Title: Servomotor system
IPC: B60T13/72
Filed: 1966-09-30
Abstract: 1,129,222. Valves; fluid pressure brakes. BENDIX CORP. 30 Sept., 1966 [11 Oct., 1965], No. 43853/66. Headings F2F and F2V. [Also in Division G3] In a vehicle braking system, an auxiliary electrically-operated control valve is provided for the conventional pedal-operated servomotor whereby, when this valve is energized, a predetermined braking effect is obtained. As shown, a conventional vacuum-suspended tandem servomotor 10 is connected by rod 86 to a master cylinder (12) and by rod 78 to a pedal (20). The two control chambers 60, 72 are connected by conduits 66, (34) and 68, (32) respectively to ports 30, 28 of auxiliary valve 14 (Fig. 3). With solenoid-operated valve 102 in the position shown, ports 28, 30 and thus chambers 60, 72 are in direct communication with each other and the servomotor responds in the normal way to pedal movement. When the solenoid 94 is energized, the valve 102 seats at 106 to interrupt communication between ports 28, 30. Port 28, however, is connected to a chamber 114, the pressure in which is maintained at a predetermined value by valve 118, 136. This pressure is thus transmitted to control chamber 72 and causes movement of the servomotor to produce a braking effort proportional to the pressure. Valve element 136 is tubular and is movable with diaphragm 116 to seat against, and unseat, valve element 118, the latter cooperating with a seat 120 carried by an adjustable hollow stem 122 whose axial position determines the pressure in chamber 114. Element 136 communicates at 38 with the vacuum manifold and stem 122 communicates at 130 with atmosphere. A further switch in the solenoid circuit is actuated by the brake pedal to de-energize the solenoid when the pedal is depressed.

Abstract: 1356205 Automatic position control R C A CORPORATION 22 Sept 1971 [24 Sept 1970] 44153/71 Heading G3R [ Also in Division G5] An element is positioned relative to a reference surface by rectroactively controlling the oscillation amplitude of a transducer, coupled to the element, to vary the thickness of a squeeze gas film between the transducer and the reference surface. In an embodiment, the position of a signal transducer relative to a magnetic memory disc is controlled through a differential amplifier 52, which compares a signal from a capacitive or inductive position sensor 50 with a reference Vref, which may be variable, to regulate the amplitude of oscillation of a Piezo-electric transducer 44 i.e. the squeeze film thickness, against an external force e.g. a spring-bias or gravity acting on the signal transducer towards the disc. The amplifier 52 may vary the amplitude of transducer oscillations by changing the gain of amplifier 54 or by varying the frequency of crystal oscillator 56 away from the resonant frequency of the Piezo-electric transducer. This transducer 44 Fig. 3, which is a half wavelength oscillator and which may be fitted with an acoustical transmission horn 49, is mounted, using a metal quarter wavelength isolator 38, on arm 30, which is radially adjusted on the disc (13) Fig. 1 (not shown) using a rack and pinion (22, 24) driven by motor (26), and biased towards the disc by a compression spring (36), a torsional spring, a gas bellows or gravity.
