Title: Engine support
Inventor: HAMAEKERS ARNO
IPC: F16F9/34
Filed: 1990-02-28
Granted: 1994-10-04
Abstract: A hydraulically dampened engine support includes two working chambers which are, each at least partly defined by an elastic body, filled with a hydraulic liquid and communicate through a damping passage.  At least one of these working chambers further communicates with a compensation chamber through a compensation passage.  The compensation chamber is, at least partly, defined by a flexible, substantially non-elastic wall providing a pressure-free uptake of liquid.  The compensation passage has a substantially higher flow-through resistance than the damping passage.  Such an engine support provides a good damping of vibrations due to road unevenness and a good insulation of acoustically prominent high frequency vibrations transmitted by the engine, even when employed in enclosed, sound proof engine compartments of motor vehicles.  The pressure of the liquid in the working chambers is held substantially constant which provides for an extended service life of the engine support.

Granted: 1994-03-15
Abstract: LINT FILTER SIGNAL FOR AUTOMATIC CLOTHES DRYER          ABSTRACT OF THE DISCLOSURE A microprocessor controlled clothes dryer wherein the posture of a switch in the lint filter system is monitored and a signal to CHECK FILTER is displayed if the switch posture has not changed.  The switch is a reed switch mounted stationary on the lint filter assembly and a magnet operator is attached to the removable filter screen. Movement of the filter screen into and out of filtering position in the lint filter assembly of the exhaust duct changes the posture of the magnet operated reed switch. Change of posture of the switch through its cycle impresses a change of voltage on the microprocessor.  The microprocessor effects control over the CHECK FILTER signal that is visually illuminated on a VFD tube: such that, if the microprocessor sees the cycling of the switch the CHECK FILTER signal is extinguished.

Title: Method and apparatus for preventing local bunching of cars in an elevator group with variable traffic flow
Inventor: MACDONALD ROBERT
IPC: B66B1/18
Filed: 1992-03-11
Granted: 2003-11-18
Abstract: A method of minimizing car bunching at any traffic flow level allocates closely adjacent stops to a given car which is favored by a variable, readjustable distributor bonus. The estimated lost time costs of all passengers are computed for each elevator and for each hall call, these costs are reduced by a variable distributor bonus concentrating adjacent stops in one car, and a hall call is then allocated for service to that elevator which displays the lowest, reduced estimated lost time costs.      In order to assure the function of this method equally at high and low traffic levels, the variable distributer bonus (Bvn) is readjusted to the traffic flow level (Va) which serves as a tracking parameter by means of a tracking function according to the relationship Bvn =      Bv.cndot.F(Va) and the readjusted variable distributor bonus is defined thereby. The tracking function F(Va) is determined by one of artificial intelligence methods and expert programs. By the dependence of the distributor bonus on traffic flow, the desired small local bunching of elevator cars is an optimum for every traffic level. This method is applicable to a plurality of different allocation criteria, service requests and tracking parameters.
