Abstract: A weighing apparatus for a vehicle (15) having tines (16) in which a ramp (60) is mounted on each tine (16) in front of and in spaced relation to a weighing load bearing plates (40). The ramp (60) and the confronting weighing load bearing plates (40) are not mechanically joined. Below each weighing load bearing plates (40) are load cells (21) for emitting changes in signals representative of the weight of a load on the weighing load bearing plates (40). As the load advances toward the weighing load bearing plates (40), the ramps (60) attenuate excessive forces and shock resulting from the load advancing onto the weighing load bearing plates (40). As a consequence thereof, the load cells (21) are not subject to the excessive shocks or forces of an advancing load.

Abstract: A torque-generating steering device is provided for use with a pump (19) having a pressure compensator (23) for varying the output of the pump. The device includes a gerotor displacement means (43) which provides a relatively high-torque output to an output shaft (29) in response to the flow of fluid through the gerotor. A spool valve (73) and sleeve valve (75) define a fluid path (119) from an inlet port (13) through the gerotor to an outlet port (15). The fluid path includes a main variable flow control orifice (121) in series flow between the inlet and the gerotor, the orifice having a zero flow area when the spool and sleeve are in their neutral position, and a maximum flow area when the spool and sleeve are in an operating position. The device defines a load-sensing port (115) communicating with the pressure compensator (23) and with the fluid path (119), downstream of the orifice (121).

Abstract: Broadband amplifier stages with field effect transistors as the amplifying element, whose amplification is varied with the aid of the drain current with a fixed drain-to-source voltage UDS, require above-average operating voltages in order to be able to maintain the condition UDS = constant. The DC amplification of the amplifying element is generally not adequate to maintain the drain-to-source voltage constant with low currents. According to the invention, a higher-amplification operational amplifier is inserted into the feedback branch in order to stabilise the drain-to-source voltage. The voltage source -U1 for setting the gate bias voltage then drives a constant current through the voltage divider to set the gate bias voltage, which produces a constant drain-to-source voltage UDS.

Abstract: In the improvement to a locking device (3) of this invention, a slider (11) is mounted for sliding by a card key with tumblers (21 - 25) being pushed in the sliding direction by the card key. In addition, since the tumblers (21 - 25) are pushed into the slider (11), the slider (11) does not prevent the card key from sliding. Consequently, unlocking or locking operations can be attained by sliding the card key along the tips of the tumblers (21 - 25) without stopping of the card key by a step portion. Therefore, the improvement to a locking device (3) of the invention effects smoother unlocking or locking operation than a conventional locking device.
