20150144053 | PRESSURE DIFFERENTIAL INDICATOR - A pressure differential indicator that eliminates the risk of providing a false positive due to fluid contamination. The invention has an electrically insulated barrier between the “hot” pin and the grounded housing without the need for a hermetic seal. The indicator can be manufactured at a greater efficiency and lower cost than is found with prior art pressure differential indicators. It has a piston that can be easily oriented to yield either a normally closed or normally open position. The indicator has at least one protrusion on a plastic overmold to engage the swage collar and resist axial rotation of the pin. A pressure seal interrupting the plastic overmold sections and exposing the underlying metal to allow for an O-ring seal with no potential leak path between plastic and metal. Finally, the pressure differential indicator has all moving components contained within a single cavity. | 05-28-2015 |
20150132429 | PLASTIC PUMP HOUSING AND MANUFACTURE THEREOF - A method of making a pump housing that is net-molded and immediately assumes its final shape and design specification without requiring more than de minimis secondary machining processes. The method utilizes molds and cores configured such that none of the fluid ports of the housing produced using the molds and cores have any intersecting geometry. | 05-14-2015 |
20140329672 | Method and Apparatus for Applying Particulate - A particulate feeding apparatus for applying particulate, such as super-absorbent materials, to a substrate, such as a fibrous web. A feeder tube for the powder and a rotary gate valve, including one or more holes is provided. This structure may then intermittently feed particulate to an eductor or venturi nozzle. The rotary valve provides an intermittent supply of particulate to a relatively low-pressure zone at the nozzle formed by the venturi action of the passing air stream and the particulate may be distributed precisely where desired. A process for delivering powder to a substrate in precise amounts and distribution patterns is also disclosed. | 11-06-2014 |
20140318382 | QUICK HEATING QUARTZ TOASTER - A commercial toaster apparatus having a “quick start” feature that nearly instantly changes from a “stand-by” mode to a “toasting” mode. The “quick start” mode is provided by changing the circuitry of some of the quartz heating elements from a series configuration to a parallel one wherein a higher voltage can be applied for a controlled amount of time to regulate the quartz heaters without adversely affecting the life span of the heating elements. Temperature probes are used to adjust the duty cycle of the apparatus to enable a uniform toast color as the cavity chamber temperature of the toaster changes over time. A sensor is also provided that determines when a last product is placed on the conveyer and the duty cycle has been completed such that the unit will automatically switch to a “stand-by” mode, thus reducing the energy requirements of the toaster. | 10-30-2014 |
20140205459 | HIGH OUTPUT FAN WHEEL - A high output bent fin type of fan wheel for use in appliances such as but not limited to microwave ovens.

Unique to fan wheel is the large fan blade surface area in relation to the total area of the metal used in wheel. | 07-24-2014 |
20140203652 | CURRENT DETECING AND SWITCHING APPARATUS - A current detecting and switching apparatus that provides automatic coupling of internal components of an appliance to varying supply voltage sources to prevent components from operating at something other than their intended power rating. The switching apparatus provides automatic coupling to multi-rated internal components of the appliance instead of providing a voltage specific appliance pre-wiring of specific connections of a multi-voltage component. | 07-24-2014 |
20140202444 | VORTEX SHEDDING HEAT TRANSFER METHOD AND APPARATUS - A heating transfer method and apparatus that has a fixed physical obstruction placed in the air path causing the airflow to cause the airflow to shed into alternating patterns. A column is placed perpendicular to the airflow path to provide an obstruction to the airflow. The cross-section of the column can be round, square or another multi-sided design. The obstruction will affect the velocity and intensity at which the shedding occurs thus, causing motion of the jets to deliver a more uniform cook on the product surface. | 07-24-2014 |
20140197163 | MICROWAVE MODE STIRRER APPARATUS - A mode stirrer apparatus that enables a more effective heating pattern in the food that is to be cooked. Two mode stirrers located in opposite walls of the oven. Each mode stirrer is independently driven by a small gear motor that causes the mode stirrer to rotate in only one direction. The result of this mounting configuration is that the mode stirrers rotate in a counter-rotating fashion in relation to the food being cooked. The mode stirrer in this invention has a combination of radiating slots (which behave like a rod shaped dipole antenna) and large areas of angled/displaced metal. | 07-17-2014 |
20140197161 | DOOR SWITCH APPARATUS FOR MICROWAVE OVENS - A door switch apparatus for a microwave oven that disables the microwave system while not requiring any separate “fingers” or tongs on the door face to reach into the main body of the oven to activate a switch. The switch uses stackable switches activated by a single switch lever. The switch lever is preferably made from a solid piece of ultra-high molecular weight polyethylene (UHMV to keep the accuracy of the angular dimensions between the surfaces contacting the door hinge arm and the arm of switch to remain fixed. | 07-17-2014 |
20140076138 | BALLISTIC PANEL APPARATUS - A ballistic panel composed of multiple layers. An outer layer is preferably metal. An inner layer is provided that can serve as decorative, if desired. Adhered to the outer layer is a layer of ballistic material, preferably KEVLAR or other synthetic ballistic fiber. Foamed in place is a layer of foam, preferably urethane. Also, featured is a plurality of cam locks with each cam lock having a male and a corresponding female part such that the adjacent panels can be easily and quickly locked together to form a safe enclosure. | 03-20-2014 |
20140021650 | Plastic Pump Housing and Manufacture Thereof - A method of making a pump housing that is net-molded and immediately assumes its final shape and design specification without requiring more than de minimis secondary machining processes. The method utilizes molds and cores configured such that none of the fluid ports of the housing produced using the molds and cores have any intersecting geometry. The net-molded pump housing may also include a cross-tube insert providing flow communication between a fluid inlet port and a pressure relief port. | 01-23-2014 |
20130167582 | FREEZER EVAPORATOR APPARATUS - An ultra low temperature freezer evaporator (ULT) apparatus that has a triple feed capillary tube system.
