| 20100017993 | Rotational scratch-off card surface remover - A rotational remover including a body assembly and a tip drive assembly. The body assembly includes a body front containing a convoluted bearing race, a body back which fastens to the body front and a main spring housed within. The tip drive assembly includes a bearing guide having a threaded barrel at the front end which receives a tip, a center section which receives at least three ball bearings and a spring pivot. The ball bearings are housed in the tip drive assembly rolling in the bearing guide and within the convoluted race formed in the body front assembly. The spring pivot is housed in the body assembly between the main spring and the bearing guide. The depression of the body assembly in a vertical movement actuates the ball bearings within the convoluted bearing race, thereby rotating a tip with a serrated, abrasive surface received in the bearing guide in a rotational movement. The main spring provides resistance for and returns the tip drive assembly to a starting position after the body assembly is vertically depressed. | 01-28-2010 |
| 20110146019 | Scratch-off card surface remover - A scratch-off card surface remover comprised of a single body assembly. The single body assembly contains a forward extruded scraping tip wherein the tip is a half sphere shape that contains a flat plane scraping edge and of which this shape is directly centered on and extending from the forward area of an elliptical mount formed directly to a middle obtruded hollow barrel hand grip further directly formed to an aft hollow barrel section containing two oppositely correlated perforations for the insertion of a means by which to carry and store the assembly. The horizontal movement of the single body assembly as applied to the surface of a scratch-off card empowers the scraping characteristic of the scraping tip portion of the assembly. | 06-23-2011 |

| 20110244775 | APPARATUS AND METHOD FOR CONTROLLING AND DIRECTING FLOW OF CONTAMINATED AIR TO FILTERS AND FOR MONITORING FILTER LOADING IN A BIOLOGICAL SAFETY CABINET - An improved system and method for monitoring contamination loading of a filter in a biological safety cabinet comprising a housing defining a work chamber and a filtration chamber, a system for circulating air between the work chamber and the filtration chamber via a fan which draws air under negative pressure from the work chamber and delivers the air under positive pressure through the filter and into the filtration chamber. The filter monitoring system determines a pressure differential between the negative and positive air pressure at opposite sides of the fan, and evaluates the degree of contamination loading of the filter on the basis of the pressure differential. An air flow baffle is disposed within the filtration chamber adjacent the fan for dividing the pressurized air delivered by the fan and partially redirecting a portion thereof for more uniformly delivering the air to the filter. | 10-06-2011 |
| 20110281514 | APPARATUS FOR DIRECTING AIR FLOW IN A BIOLOGICAL SAFETY CABINET - A biological safety cabinet with several air flow directional control enhancements. A perforated air intake grille within the work chamber inwardly adjacent the user access opening has a forwardly facing make-up air intake surface and a rearwardly facing internal air intake surface angled in converging relation to promote a physical division between intake of ambient air and internal air into the cabinet's air recirculation system. An aerodynamic user arm rest is affixed to a support stand to extend alongside the access opening at a spacing outwardly from the housing to assist in directing make-up air to the ambient air intake opening without cross-contamination between the arm rest and the work chamber. An air transmission grille above the work chamber has a horizontal main extent terminating at a spacing from the sash and an upwardly angled extent adjacent the sash to direct increased laminar air flow downwardly along the sash. | 11-17-2011 |
| 20140260130 | DUCTLESS LABORATORY HOOD APPARATUS - A ductless laboratory hood apparatus includes a housing defining an interior work chamber, a filtration chamber, an access window opening into the work chamber from an ambient laboratory environment, and an exhaust outlet opening from the filtration chamber into the laboratory environment, a filter system disposed between the work and filtration chambers, and an air circulation system for creating and directing an airstream to flow from the laboratory environment through the access window, the work chamber, the filter system, the filtration chamber, and the exhaust outlet to return into the laboratory environment. The filter system has both a main filter whose constituent material is highly efficient but is also degradable if exposed directly to laboratory processes, and an attenuation filter disposed between the work chamber and the main filter to intercept and attenuate laboratory processes that potentially degrade the main filter, thereby preventing degradation of the main filter. | 09-18-2014 |

| 20080243299 | Machine tool control system - A machine tool controller is provided that includes a processor configured to execute a sequence of instructions in accordance with an operating program and a user program. A volatile memory temporarily stores instructions and data during execution of the sequence of instructions by the processor, and is coupled to the processor via a first interface. A first non-volatile memory stores the operating program and is coupled to the processor via a second interface. A second non-volatile memory stores the user program and is coupled to the processor via a third interface. A video controller is configured to control a user display in accordance with display data generated by the processor and is coupled to the processor via a fourth interface. A dual-port memory is coupled to the processor via a fifth interface and couples a serial bus controller configured to control communications with an external device via a serial bus to the processor. An external bus interface is configured to communicate control commands for controlling a machine tool generated by the processor via an external bus and is coupled to said processor via a sixth interface. | 10-02-2008 |
| 20090248188 | SMART MACHINE TOOL LUBRICATION SYSTEM - A smart machine tool lubrication system monitors the distance traveled by a motion component in a machine tool. A predetermined amount of lubricant is dispensed at a lubrication point of the motion component when the monitored distance exceeds a first threshold value. The smart machine tool lubrication system may further monitor the duration of time the motion component is in motion and dispense the predetermined amount of lubricant with the monitored duration of time exceeds a second threshold value. | 10-01-2009 |
| 20090248194 | CUT OPTIMIZATION SYSTEM AND METHOD - A cut optimization system controls chatter in a machine tool during a cutting operation. A microphone is configured to capture acoustic noise emitted by the machine tool during the cutting operation and to generate an AC signal corresponding to the captured acoustic noise. A filter is configured to attenuate frequencies of the AC signal outside of a frequency band and a rectifier is configured to rectify the filtered AC signal into a DC component. A controller is configured to compare the DC component with a threshold value and, if the DC component is greater than the threshold, cyclically vary the rotational speed of a spindle in the machine tool from a commanded speed. | 10-01-2009 |
