20130125666 | VARIABLE TORQUE RATE TEST JOINT - In a variable torque rate test joint, screw-threaded first and second elements are rotated relative to one another by a tool under test. At least one spring beam is cantilevered over a pivot point to exert an axial force between the first and second elements and the torque rate of the test joint can be varied by moving the pivot point to change the axial force. The first element may be a shaft that is fixed during testing and the second element is a nut rotatably mounted on the shaft, whereby the element rotated by the tool has a minimal moment of inertia. Whichever of the first and second elements is held stationary during the test may be mounted in a hub that is locked during the test but can be rotated at the end of the test to reset the test joint. Measurements may be made of the torque and the rotation angle to derive an actual torque rate of the joint, which allows correction of errors by moving the pivot point. | 05-23-2013 |

20160049790 | ELECTRICAL ENERGY STORAGE DEVICE AND SYSTEM - An electrical energy storage device comprises an electrical connection arranged to detachably connect to a power distribution system on a site; an energy store having an input arranged selectively to charge the energy store from the distribution system, and an output arranged selectively to discharge the energy store to the distribution system; a processor arranged to monitor at least one condition relating to the site, and to monitor at least one condition relating to the energy store, and to control the energy store to charge or to discharge dependent upon the monitored conditions; and preferably a communication interface for the processor. Such a device could be provided in a domestic site, in particular a site having a generation capacity such as PV panels, in order for the energy consumer at the site to obtain an electrical energy supply more efficiently or more cheaply, and in order to smooth out fluctuations in energy supply and/or demand from the site. | 02-18-2016 |

20110144516 | RELATIVE CONTRIBUTION OF THORACIC MUSCLES TO BREATHING - A method and apparatus for evaluating the relative contribution of the diaphragm versus other thoracic muscles to breathing by obtaining measurements of parameters that correlate with changes in thoracic cavity and intra-abdominal cavity pressures over identical time increments and organizing the measurement data in manner that reveals whether the pressures changes are characteristic of the pattern of contemporaneous pressure changes in those cavities that accompany contraction and/or relaxation of the diaphragm muscles or whether the pressure changes are characteristic of the pattern of contemporaneous pressure changes in those cavities that accompany contraction and/or relaxation of the intercostal muscles. | 06-16-2011 |
20120215124 | NON-INVASIVE ARTERIAL BLOOD GAS DETERMINATION - A breathing circuit for use in conjunction with a ventilator serving a mechanically-ventilated patient includes an expiratory gas airflow pathway; an inspiratory gas airflow pathway; and a gas mixing mechanism operable to mix inspiratory gas and expiratory gas in an amount sufficient to equilibrate the patient's P | 08-23-2012 |

20120324809 | INSULATED ROOF WINDOW - A roof window frame comprising at least four elongate frame members joined about their ends forming a quadrangular shaped frame defining a central aperture. Each frame member has a main aperture facing surface and a main roof facing surface, the two main surfaces facing in opposite directions with the thickness of the frame member being defined between these main surfaces. The frame members have a reduced thickness base member and an integral insulation member carried on the main roof facing surface of the reduced thickness base member so that the overall size and shape of the reduced thickness base member and the integral insulation member is the same as an unaltered frame member for the same specification of roof window. | 12-27-2012 |
