Title: Improvements relating to anti-theft apparatus for vehicles
IPC: B60R25/021
Filed: 1955-02-14
Abstract: 776,201. Vehicle locking devices. DAIMLERBENZ AKT.-GES. Feb. 14, 1955 [Feb. 13, 1954], No. 4383/55. Class 79(3). [Also in Group XXVII] Anti-theft apparatus for a diesel-enginedriven vehicle comprises, in combination with a steering lock and fuel-injection means (not shown) for the engine, an auxiliary bolt 10, a locking pin 9 movable alternatively into recesses 6, 13 in the steering lock bolt 5 and the auxiliary bolt, and mechanism including an arm 24 on the auxiliary bolt 10 engageable by an arm 22 movable with a member 16 controlling the injection means for moving the bolt 10 so that its recess 13 is brought into position for receiving the pin 9 and so permitting locking of the steering only when the injection means has been brought into the engine-stopping position. As shown a casing 1 mounted by means of a bracket 3 on the steering column houses the steering lock bolt 5 operated by a key 7 and adapted to project into a recess (not shown) in the steering shaft 4, the shaft 4 being locked when the key is in its " stop " position. When the key is in its " driving " position the recess 6 in the bolt 5 is disposed opposite a bore 8 housing the pin 9 which is urged away from the recess 6 by a spring 12 and into engagement with the bolt 10. The recess 13 in the bolt 10 permits the pin 9 to move clear of the recess 6, and the bolt 10 is axially movable through screw or cam action by rotation of the arm 24 in order that the recess 13 may be moved clear of the pin 9, thus preventing axial movement of the bolt 5 to lock the steering shaft 4. Rotation of the arm 24 is controlled by a pin 23 on the arm 22 carried by the member 16 which also carries a manually operable arm 15 and an arm 18 which is connected by a cable mechanism 21 to the engine starting -motor switch (not shown) and the fuel injection pump means, and the shaft 16 controls an engine starting ignition switch 14. In operation movement of the arm 15 from a horizontal position clockwise to its position shown in Fig. 2 causes the engine to be started, the starting ignition means to be switched on and then off, the injection means to be adjusted and the bolt 5 to be locked in its withdrawn position. When the key 7 is moved to a " garage " position the bolt 5 is adjusted to a position between the stop and driving positions, thus enabling the steering wheel to be turned, but making it impossible to start or run the engine. In a modification, Figs. 3 and 4 (not shown), the bifurcated arm 24 is replaced by a spring-urged single arm, such arm having a recess adapted to hold the manually operable lever in the stopping position.

IPC: B64C29/00
Filed: 1956-02-14
Abstract: 800,882. Automatic steering control systems. SUD-AVIATION, SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Feb. 14, 1956 [Feb. 18, 1955], No. 4624/56. Class 38 (4). [Also in Group XXXIII] An automatic aircraft steering control system is shown in Fig. 9a. A diaphragm 93 is'subjected on one side to total pressure from an aperture 37 on the aircraft, and on the other side to static pressure from an aperture 38. The diaphragm acts on a resistance strain gauge 94. Another diaphragm 96 is subjected, to pressures from apertures 88a and 88b on the lower and upper surfaces of the fuselage, and acts on a strain gauge 97. The strain gauges are each connected in series with a potentiometer 99, and their free ends are connected to an energizing source 98. A signal picked off from potentiometer 99, having components representing functions of airspeed and angle of pitch, is fed to amplifier 100 energizing a torque motor 101 acting on a rod 12 connected to an hydraulic servo 9 controlling a surface 2, and connected through a spring-box 17 to the pilot's control column 15. Strain gauges 103 and 104 are connected to a spring-balanced weight 33 sensitive to acceleration along the z-axis, and a pitchsensitive gyro 43, and the resulting signals are fed to an amplifier 105 energizing a torque motor 106 also acting on rod 12. While the pilot controls the column 15, forces exerted on rod 12 by motors 101, 106 compress the spring box, and are superimposed on the forces exerted by the pilot, and in the steady state, the force on the control column is trimmed out by an adjustable spring 50. When the pilot flies " hands off," the forces exerted by motors 101, 106 keep the aircraft on the course determined by the setting of spring 50. Similar systems are used for the roll and yaw controls, which are each subjected to a force derived from a diaphragm connected to apertures, one on each side of the aircraft, and to a force derived from roll and yaw sensitive gyros respectively.

Filed: 1936-02-17
Abstract: 470,757. Aircraft with rotary wing systems. HUTCHISON, H. H., and GIBSON, J. J. Feb. 17, 1936, No. 4724. [Class 4] A rotary-wing aircraft has the rotor mounted on the fuselage to rock about an axis located transversely with respect to the latter and also to rock about a fore and aft axis which always passes through the centre of lift of the rotor blades, the rotor being rotatably mounted on a member which is displaceable along a guide connected with and located transversely to the aircraft fuselage and the guide is so formed that the displacements of the member along the guide are executed about the centre of lift of the rotor. A rotor head 1, Fig. 2, is carried by an upstanding pin 4 integral with a bifurcated quadrantal member 5 adapted to embrace an arcuate bar 6 of rectangular crosssection. The centre of curvature of bar 6 is the centre of lift 7 of the rotor head. Member 5 engages bar 6 by means of pins 8 carrying pairs of rollers 9. Bar 6 is formed with trunnion bearings 10 journalled in rotor support member 15. Rotatably carried by trunnions 10 is a yoke 13. Bar 6 carries at each end a frame 18, Fig. 4, formed with gear teeth 19 meshing with a pinion 20 of which the axle extends through an aperture in yoke 13 and is journalled in bracket member 15, Fig. 2. Each pinion 20 also engages a rack 22 secured to yoke 13. Means for moving quadrantal member 5 laterally and for rocking bar 6 about the axis of trunnions 10 comprises a control column 27, shown diagrammatically in Fig. 1, mounted midway of its length about fore and aft pivots in yoke 13 and formed with forks at a upper end engaging pins 25 secured in the cheeks 5a of member 5. Fore and aft movement of lever 27 causes fore and aft tilting movement of the rotor head by reason of the presence of reversing pinion 20. Lateral movement of lever 27 causes corresponding lateral tilting of the rotor head.
Patent GB-889026-A (GB)
Title: Improvements in or relating to voltage regulators
IPC: H02J7/16
Filed: 1958-02-13
Abstract: 889,026. Automatic voltage-control systems. MINNEAPOLIS - HONEYWELL REGULATOR CO. Feb. 13, 1958 [Feb. 14, 1957], No. 4764/58. Class 38 (4). The output voltage of a self-excited D.C. generator for use on a motor vehicle (or, it is stated, an A.C. generator and rectifier) is stabilized, and the output current limited, by control of a bi-stable pair of transistors, one of which has the field winding as the collector load. The generator 10 supplies a battery 17 and an external load through a main rectifier 23 which replaces the conventional cut-out. The generator field 11, shunted by a rectifier 47 to reduce switching surges, forms the collector load of a transistor 26. The base of transistor 26 is directly coupled to the collector of a control transistor 27 and the two are cross-connected by a resistor 67 shunted by a capacitor 71 to form a bi-stable pair. The base of transistor 27 is connected through a Zener diode 77 to a point on a potential divider across the output terminals-the potential divider consisting of the resistors 75, 73 and the low impedance of a normally conductive transistor 30. When the portion of the output voltage tapped off the potential divider exceeds the break-down voltage of the Zener diode 77, the base of transistor 27 becomes more negative, and the resulting emitter/collector current cuts off the transistor 26. The non-linearity of the diode 43 included in the emitter circuit of the transistor 26 ensures that the transistor is cut off.. The resulting fall in output voltage reverses the above action, causing the transistor 26 to again become fully conducting and the cycle repeats. Current limiting is effected by controlling the transistor 30 in accordance with the voltage drop across a resistor 21 carrying the load current, so that as the load current increases, the transistor 30 passes less current and the regulating point of the potential divider 73, 75, 30 is lowered. Conversely, the voltage drop across the main rectifier 23 is applied via a diode 96 to the emitter of transistor 27 to increase the output voltage to compensate for the drop across the rectifier. The base of transistor 27 is also biased via a diode 91 to ensure that it is cut-off when the generator is building up. In a modification, Fig. 2 (not shown), the load current measuring resistor 21 is omitted, and the voltage drop across the rectifier 23 is applied to the emitter of the transistor 30 (now connected in a common base circuit) to adjust the regulating point of the voltage measuring circuit, which is slightly re-arranged. In a further modification, Fig. 3 (not shown), the current control transistor 30 is omitted, and a portion of the voltage drop across the rectifier 23 is applied directly to the base of transistor 27. The diode 43 in the emitter circuit of transistor 26 is replaced by a biasing potentiometer.
