Patent GB-972651-A (GB)
Abstract: 972, 651. Cash registers. G. H. GLEDHILL & SONS Ltd. Nov.30, 1960 [Dec. 1, 1959], No. 40713/59. Heading G4T. In a key set and operated cash register of the type described in Specification 368,785 connections comprising link mechanisms are pivotally connected between the key coupler and the re-setting bar. This is done in order that the transmission of reciprocating movements to the re-setting bar can be made more smoothly and with lighter pressure on the keys than with the connecting mechanisms usually employed. As a key A is pressed a common key coupler F moves upwards raising a pivoted cam plate 15 so that a slot 21 rides over a fixed roller 22, the motion being slowed down at each end by virtue of the shape of the slot. Thus when the key coupler F is approaching either the upper or lower end of its movement, the motion imparted, via links 14, 13 and crank arm 12, to the re-setting bar C, is slowed down. Initial adjustments may be made to vary the angular disposition of the link 13, by altering the position of an extension 18 to the link 14 on the plate 15 by means of a screw 16 and slot 17.

Title: Increasing an output impedance of a transmit amplifier during receive mode of a two-way communication unit
Inventor: LEIZEROVICH GUSTAVO D
IPC: H04B1/52
Filed: 1999-02-25
Abstract: The communication unit 200 includes a transmit amplifying device 201, an antenna 209 and a signal receiver 211. During the receive mode the transmit amplifier remains coupled to the antenna but a bias 225 is applied to the amplifying device to increase the output impedance (Zout) of the transmit amplifier such that the transmit amplifier does not significantly load the received signals. This means that no switch is necessary to disconnect the transmit amplifier from the antenna during reception. A supply voltage 223 may also be applied to the transmit amplifier in addition to the bias voltage in order to achieve a high receive mode output impedance. The bias applied when in the receive mode may be greater than the bias applied to the transmit amplifier when in the transmit mode. The transmit amplifying device may be a depletion mode GaAs FET device.
