Patent GB-1303998-A (GB)
IPC: B60T7/04
Filed: 1970-11-10
Abstract: 1303998 Controlling motor vehicles A A LA CHIUSA 30 April 1970 [21 May 1969] 53478/69 Heading B7H A foot operable control for actuating brakes and throttle of a vehicle comprises a brake lever 22 to which is pivotally mounted an accelerator lever 21 having a foot pedal 23 thereon, the arrangement being such that relative pivotal movement between the levers 21, 22 will control the throttle and concurrent movement of the levers 21, 22 will control the brakes. Brake lever 22 is pivoted about a shaft 32 and has a stop 45 engageable by the accelerator lever. The accelerator lever 21 is connected to a throttle control-rod 87 via a link 121 having a slot in which a roller 76 on the lever moves, the lever 21 being pivoted on the brake lever at 46. By such an arrangement, with a surface 65 of accelerator lever in contact with the stop 45 concurrent movement of both levers 21, 22 results in braking of the vehicle while the throttle is in an "engine-idling" position. Upon releasing pressure on the pedal the brakes are released and as the accelerator lever pivots upwardly relative to the brake lever the throttle is progressively opened. Total absence of pressure on the pedal, however, causes the throttle to be placed automatically in the "engine-idling" position. This is achieved as follows:- Tlie accelerator lever 21 comprises a lower portion 58, 58<SP>1</SP> and an upper portion 67 normally retained in engagement by a pin 70 on portion 67 engaging slot 72 in shaft 66 of arm 58<SP>1</SP>. The pin is movable under the action of a solenoid 68 in circuit with a switch 91 in arm 58. Pedal 23 is pivoted to lever 21 such that in the position shown in Fig. 1, in which pedal plate 112 and lever plate 108 are out of contact, switch 91 is closed to actuate solenoid 68 which withdraws the pin 70 from slot 72. Upper portion 67 is thus released from portion 58, 58<SP>1</SP> and under the action of spring 84 is urged to place the throttle in the "engine idling" position. Following release of the upper and lower portions a further switch 77, 79 is opened to re-activate solenoid 68 to re-extend pin 70 so that when pressure is later exerted on the pedal the lower and upper portions reconnect by snap-action. Means are provided for preventing the brake lever moving to apply the brakes while the throttle is open. Such means comprise a rotatable cam member 48 on the brake lever, a stop 56 on a fixed mounting and a roller 57 on the accelerator lever. Normally one cam surface of cam member 48 will abut the stop while the throttle is open to prevent application of the brakes, but as the throttle is closed roller 57  rotates cam member 48 to a position in which stop 56 will ride over another surface of the cam member so that the brake lever can be moved to apply the brakes.

First and second diodes may be shunted across the whole tuned circuit, the second diode being in series with a resistor (Fig. 2, not shown) or a single diode in series with a variable resistor may be used (Fig. 3, not shown). A diode may alternatively be connected in series with the inductor of the tuned circuit, being shunted with a variable resistor (Fig. 4, not shown). In the case of a series resonant circuit the diode may be placed across the inductor, the capacitor, or both (Figs. 5-7, not shown) or may be placed in series with the circuit, being shunted by a variable resistor (Fig. 8, not shown).

PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 Nov., 1968 [28 Nov., 1967], No. 55814/68. Headings H3T and H4R. In a television community aerial system a repeater amplifier is provided which comprises a normal amplifier (1, Fig. 1, not shown), and a standby amplifier (4, Fig. 1) the output of the normal amplifier being monitored and compared with its input and the standby amplifier switched into circuit if the normal amplifier fails. An oscillator (Fig. 4, not shown) is also connected to the circuit and energized with the standby amplifier to provide an indication of the normal amplifiers failure. A pilot signal may be transmitted from the central station of the system to provide a signal for the amplifier failure detector, the pilot signal being derived from a generator (Fig. 5, not shown) including a normal oscillator and a standby oscillator brought into operation if the normal oscillator fails. Both the amplifier and oscillator changeover are effected by bi-stable circuits which when triggered to energize the standby circuits remain in that condition until the power supply is interrupted for a short time, when they switch to the normal operation state. The monitoring of the input and output is effected by comparison of D.C. voltages derived by rectifying the respective signals, the comparison result operating the bi-stable to effect switching of the power supply to the amplifiers.
