Title: Improvements in or relating to hand electric steering gear for dirigible crafts
IPC: G05D1/02
Filed: 1932-08-12
Abstract: 390,051. Control of motors. SPERRY GYROSCOPE CO., Inc., Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.- (Assignees of Hodgman, F. S.; 111, Valley Road, Glen Rock, New Jersey, U.S.A.) Aug. 12, 1932, No. 22686. Convention date, March 26. [Class 38 (iii).] A combined hand and electric steering-gear for ships and aircraft is arranged with a lost motion connection between the engine control and the wheel, whereby the wheel on initial hand turning can bring the engine into operation whilst a followback connection normally stops the engine when the wheel is stationary. The hand-wheel 1 is adapted to move a shaft 9 which is geared to the shaft 16 operating the cable drum 18 and cable 19 which actuates a rudder 20. The drum 18 is also adapted to be operated by gears through a magnetic clutch 42 from an electric motor 21. In the pedestal 2 the drive from the wheel is by gear-wheels 4, 5 to a shaft 6 carrying a dog clutch 7. An intermediary dog clutch 10 gears in turn with a dog clutch 14 secured to the shaft 9. These dog clutches are provided with spaces which give a lost motion and may be faced with felt to reduce noise. In the ordinary way hand steering would be effected through these dog clutches. The dog members 7 and 14 however each carry spur-wheels 22, 25 engaging nuts 23, 26 respectively in which operate a rod 28 which screws into the lower nut 26 and is slidingly splined in the upper nut 23. This rod 28 has a collar engaged by a pivoted member 32, the end 34 of which is adapted to make contact with contact points 35, 36 in the electric motor circuit. On the turning of the hand-wheel therefore, there will be a relative motion of the spur-wheels 22, 25 which will result in a longitudinal motion of the rod 8 whereby contact will be made and the motor started. At the same time the magnetic clutch 42 is energized and the motor will rotate the cable drum 18. For the follow-up mechanism, spur wheels 45 are employed. In order that the hand wheel need not be continuously rotated in order to produce rudder motions, relays may be imposed in the motor circuit, the magnetic relays 49, 50 completing the circuit between contacts 51, 151, 52 and 152 to send a current through the motor armature 53 in the required direction and also through the series field 54. When the respective relays are de-energized, they establish back-contacts 55, 55<1>, and cause dynamic braking by shortcircuiting the armature through resistance 56. Limit switches 57, 57<1> are provided to limit the throw of the rudder in each direction. In addition to dynamic braking an electromechanical brake 61 is also provided for the motor shaft. In order that continuance of the operation may be ensured, one of the members 11 of the dog 10 is provided with springs 66 having roller ends 69 which are adapted to snap into and out of engagement with the faces 8 and one of the other dog members.

Title: Linearizing circuit
Inventor: LEY ANTHONY JOHN
IPC: H03K7/00
Filed: 1970-05-12
Abstract: 1294489 Measuring frequency non-linearly SOLARTRON ELECTRONIC GROUP Ltd 29 April 1971 [12 May 1970] 23001/70 Heading G1U [Also in Division H4] In order to produce a signal which varies linearly with a physical variable from the output of a transducer that produces a pulse train whose frequency varies non-linearly with the physical variable, every Nth pulse from the transducer 12, Fig.1, both sets a trigger 18 'on' causing its Q output to go high, see Fig. 3, and resets a counter 10 to zero, the trigger 18 remaining 'on' for a fixed duration To until a preset number of pulses from a reference oscillator 11 has been counted, whereupon it is set 'off' by a comparator 16, and the whole process is repeated indefinitely producing waveforms Q and Q, Fig. 3, having the stated mark/period ratios, which waveforms are applied to a circuit Fig. 4 so designed that its effective gain varies in such a way as to produce an output signal whose amplitude varies linearly with the physical variable. In the example considered, the period of the pulse train from the transducer is denoted by T, N is taken as unity and the particular transducer characteristic is assumed to be such that the desired output voltage will be proportional to #T/To (1 + To/T), where T = To + #T and To is constant. The waveforms shown in Fig. 3 are applied as indicated to gates 20, 23 and 27, Fig.4. Thus for the amplifier 21, Fig.4 the mark/period ratios #T/T and To/T effectively determine its input and feedback resistances, and hence its output signal is #T/T¸To/T = #T/To. This signal is applied to an amplifier 30 directly over a resistor 29, and via a path including an amplifier 25, where it is divided by the signal To/T, so that the resulting output from the amplifier 30 is proportional to #T/To + T#T/To<SP>2</SP> = #T/To (1 + To/T). Optionally, especially when this signal represents fluid density, it may be converted into a corresponding mark/space ratio (Fig. 5 not shown) for gating with pulses derived from a flow meter in order to determine mass flow, or Fig. 6 (not shown) the reference voltage source 15, Fig. 4 may be replaced by an appropriate analogue flow meter. In a second embodiment Figs. 7, 8, 9 (not shown) a circuit is described for linearizing a transducer having a slightly different characteristic.

Title: Improvements in or relating to transmission gearing for vehicles
IPC: A01B61/00
Filed: 1935-08-16
Abstract: 451,158. Motor vehicles and tractors. WILKENS, F. W., 50, Kaiserring, Mannheim, Germany. Aug. 16, 1935, No. 23050. Convention date, Aug. 21, 1934. [Class 79 (ii)] [See also Group XXXII] In an elastic or yielding driving- gear comprising a driving pinion e gearing with a toothed wheel f on the road wheel a, the axles b, d of the wheels f, e being connected by a spring-loaded arm c which resists the driving torque, the arm c is controlled by a pneumatic spring s. Thus, especially when a vehicle or implement is being towed, any excessive resistance to motion of the vehicle will cause the pinion e to roll on the wheel f and the arm c to rotate against the action of the spring, and thus avoid stalling the engine. In the construction shown, the pinions e are fixed on the ends of the driving shafts of an ordinary vehicle axle d after the road wheels have been removed. The arms c are journalled on the ends of the axle d and the road wheels are mounted on the ends of the arms. The vehicle body is mounted in the usual way on the axle d. Counter-clockwise movement of the arms c is limited by stops k. Each arm c has a projection h connected to a piston i working in a cylinder p formed in a casing or frame m. The two casings m are pivoted at n to the chassis frame and their rear ends are connected together by the axle d and a member o. The axle d. arms c, casings m and the road wheels form a detachable unit. Liquid is trapped between each piston i and another piston r which works in an air cylinder formed at the front end of the casing m. Thus, when piston i is moved to the left by the arm c it acts through the liquid on piston r and thereby compresses the air behind the latter piston. An auxiliary spring x may also act on the piston r. The effect of the air cylinder may be adjusted by varying the initial air pressure or by the use of auxiliary reservoirs y in communication with the cylinders through valves z. Liquid leakage past the piston i is prevented by a small pump continuously driven by an eccentric u, but only operative when the liquid in the sump m<1> rises sufficiently to lift a float v and thereby allow the suction valve of the pump to close. The pump delivers the liquid to the space q through a bore w.
