Abstract: A "universal" end fitting for a central vacuum cleaner hose, having a reversible electrical connector body that can be reversed without being disconnected from the end fitting, and which accordingly need not be realigned after being reversed, is provided.  The connector body is permanently but rotatably affixed to the end fitting.  Because it is permanently affixed, the connector body need not be realigned after being rotated to a new position.

Granted: 1999-05-25
Abstract: An actuator and programmable amplifier is operative for use with an expanding plug gage head operated by an axially movable plunger having a tapered operating end and an opposite cross head end.  The cross head end of the plunger is releasably received and secured through a slot in a retracting lever which is pivotably mounted in the actuator/amplifier housing.   A compression spring normally urges the plunger to a fully extended position within the gage head. The retracting lever is actuatable for withdrawing the plunger from the gage head.   The actuator/amplifier device includes a transducer having a core which  is  coupled to the  crosshead end of  the plunger. The transducer is operative for measuring an axial position of the plunger within the gage head.  The programmable amplifier includes a memory for storing a plurality of sets of configuration data for a plurality of  different  gage  heads.    Each  of  the  sets  of configuration data includes a predetermined measuring dimension  of  the  gage  head,  and  a  predetermined amplification factor of the tapered operating end of the plunger of the gage head.  The amplifier further includes a key pad for inputting configuration data to the memory and for selecting one of the sets of configuration data from the memory.  A central processor is programmed to convert the sensed axial position of the plunger to a measured dimension according to the selected set of configuration data.  The measured dimension is output to a digital liquid crystal display.

Patent CA-2160443-C (CA)
Title: Booster compressor system
Inventor: KEDDIE DAVID
IPC: F04C11/00
Filed: 1995-10-12
Granted: 2002-10-01
Abstract: A  booster  compressor  system  modulates  discharge pressure with a proportional regulator in fluid communication between the compressor discharge and a servo control for a valve to the compressor inlet.  The servo control comprises a double acting piston connected to  a valve control  rod.   In  one embodiment, the proportional regulator is of a negative signal type and communicates to a side of the piston for urging the piston to a valve opening position.  A valve dosing pressure is applied by a non-relieving regulator in fluid communication between the compressor discharge and the other side of the servo control piston.   As the discharge pressure  increases,  the proportional  regulator outlet  pressure  decreases  thereby resulting in the servo control allowing the intake valve to the compressor  inlet  to  close.    This,  in  turn,  reduces  the compressor  discharge  pressure  thereby  resulting  in  the proportional regulator controlling the valve to partially open once more.  In a second embodiment, the proportional regulator is of a positive signal type and communicates to a side of the piston for urging the piston to a valve closing position.   A valve closing pressure is applied by a non-relieving regulator in fluid communication between the compressor discharge and the other side of the servo control piston.

Granted: 2000-09-26
Abstract: A pulse-based cable crosstalk measurement instrument  provides near-end cross talk (NEXT) information for characterizing the performance of local area network (LAN) cable systems. Accuracy of the cross-talk measurement is enhanced by measuring and mathematically removing the cross-talk effects of the near-end connector. Accuracy of the cross-talk measurement is further enhanced by conducting the cross-talk measurement with pulses of differing pulse widths selected to have increased pulse energy in frequency ranges of interest. A composite cross-talk response using the individual cross-talk responses of the individual pulse widths concatenated together is created and then compared with an industry-standard pass fail limit to provide a pass-fail decision on a LAN cable test system under test.

Title: Removal of noxious oxidants and carcinogenic volatile nitrosocompounds from cigarette smoke using biological substances
Inventor: STAVRIDIS IOANNIS
IPC: A24D3/16
Filed: 1994-06-27
Granted: 2007-05-22
Abstract: This invention refers to a method of withholding noxious compounds contained in cigarette smoke (NO, NOx, carcinogenic nitrosocompounds, free radicals, H2O2, CO, aldehydes, and trace elements) which were up to today insufficiently retained by conventional cigarette filters. The method described specifically refers to the enrichment of common convention filters with biological substances of the metal ions (Fe2+, Cu2+, Mg2+) complexed with porphirin ring as well as Fe2+ ions stereospecifically bound to protein molecules, either separately or in combinations. The enrichment of these conventional filters with the abovementioned biological substances alters neither the physical properties of the cigarette smoke (odor, taste and appearance) nor the physical properties of the filter itself.

Abstract: A system to enable assembly of components to create a smokable cigarette at home by a consumer includes an empty cigarette tube, usually with an attached filter, tobacco product in rod-like form in a generally rod-shaped combiner device. The tobacco product is a supply of tobacco corresponding to the empty space in the cigarette tube with the tobacco wrapped in a disposable wrapper. Only the tobacco and not the wrapper is smoked. The rod-shaped combiner device is self-supporting on a surface such as a kitchen table in a position with its general axis extending upwardly from the table. A slider mechanism on the combiner device grasps the wrapper. In order to assemble the cigarette the smoker inserts the wrapped tobacco supply into the cigarette tube and positions the assembly over the combiner device. The slider mechanism then withdraws the wrapper while holding the tobacco in place to leave a finished cigarette. The finished cigarette is substantially the same as a factory made cigarette in appearance.

Abstract: A power steering system includes first and second valve members (40 and 42) which are movable relative to each other to port fluid to a vehicle power steering motor (31) and a pump (24) for providing fluid to the first and second valve members (40 and 42) and the power steering motor.  A force transmitting member (116) is connected with the first valve member (40) and movable toward and away from the second valve member (42) for applying a force to resist relative movement between the first and second valve members.  A fluid pressure chamber (138) receives fluid from the pump (24), the pressure of which acts on the force transmitting member (116).  The first and second valve members (40 and 42) include passages for conducting fluid to the fluid pressure chamber (138).  A fixed size bleed orifice (182) conducts fluid from the pressure chamber (138) to a reservoir (32).  The orifice (182) restricts the flow of fluid from the chamber (138) to the reservoir (32).          A variable speed motor (14) which drives the pump (24) varies the flow rate of fluid to the chamber (138) as a function of vehicle speed to vary the pressure in the chamber.

Abstract: Left and right driven wheels are connected to a pair of continuously variable transmissions and independently driven. The driven wheels are increased or decreased in speed at the same rotational numbers by operation of a change lever so as to move a vehicle forward or backward. When a steering angle of a steering wheel exceeds a predetermined value, an inner wheel speed during turning of the vehicle is decreased and an outer wheel speed during turning of the vehicle is increased so as to turn the vehicle. If the steering wheel becomes greater than the predetermined value during forward running of the vehicle at a low speed, the inner driving wheels stop and the vehicle does a stationary turn. However, during forward running at a high speed or backward running of the vehicle, even if the steering wheel becomes greater than the predetermined value, the vehicle does not do a stationary turn. With this arrangement, it is possible to always obtain the optimal steering characteristic in accordance with variations of the vehicle speed or the steering wheel.
