Filed: 1956-03-21
Abstract: 804,775. Motor vehicle driving gear. GLEASMAN, V. E. March 21, 1956, No. 8801/56. Class 79(2) [Also in Group XXIV] In a differential gear the casing 30 rotated by a gear 32 has pairs of worm wheels 60 mounted therein. The worm wheels of each pair carry imtermeshing spur gears 61 and gear with worms 70 fixed to the wheel axles 75. The diameter of the worms 70 is greater than that of the worm wheels. This arrangement ensures equal driving power to be transmitted to the wheel axles and prevents wheel spinning. Unequal power may be transmitted to the wheel axles by making the spur gears 61 of differing sizes or by giving the worms 70 different lead angles. As applied to a vehicle, forward and rear axle shafts 90,. 113, Fig. 10, are driven through differentials 91, 112. Differential 91 is driven from one output member of a differential 101 through gearing 92...95 and the other differential 112 is driven from the other output member 103 of the differential 101 through a universal joint 104 and gearing 107 ...110. Thus the power may be distributed between the axles either equally or unequally according to the type of differential fitted.

Title: Vertical gyro monitor system
IPC: G01C19/44
Filed: 1959-03-16
Abstract: 860,171. Gyroscopic apparatus. BENDIX CORPORATION. March 16, 1959 [March 31, 1958], No. 9040/59. Class 97(3) In an airborne system including a gyro vertical 40 and a rate-of-turn detector 132 a circuit 10 is arranged to operate a flag alarm circuit 30 and/or operate a circuit 28 to disengage the automatic pilot when the bank angle is indicated as being in excess of a prescribed threshold value and the rate-of-turn as indicated by the detector 132 is not in excess of a prescribed threshold value. Such a condition could be caused by a faulty gyro erection system or a failure of the detector 132 which normally controls the cut-in of the erection system. As shown the automatic pilot is engaged and the flag alarm put out of operation by relays 24, 26, operated by winding 22 energised through circuit 10 and source 12. Switches 14,16, 18, 20 in circuit 10 are closed during normal operation but are biased to the open position and are allowed to open when various faults develop. Switch 14 is closed by energisation of winding 32 when current is flowing from source 50 to the gyro motor 48 and switch 20 which has a bimetallic strip is closed by heater 38 fed from an amplifier 55 as long as gyro motor 48 is taking power from source 50. The heater 38 and amplifier 55 are arranged so that switch 20 closes e.g. one minute after motor 48 is energised which is long enough to ensure that the gyroscope 40 is properly erected. The time delay thermal relay 16, 34, is closed provided either switch 94 operated by coil 98 or switch 95 operated by coil 99 is closed. A bank gimbal synchro 114 has a rotor winding 116 positioned by a shaft 120 on the bank axis of the gyro and stator windings 122 connected to stator windings 111 of a synchro 109 whose rotor winding 107 is set at a predetermined position. When the bank angle is low the amplifier 103 energises winding 98 but on the bank angle exceeding a threshold valve as determined by rotor winding 107 the resulting signal applied to the amplifier 103 results in the latter cutting off the power supplied to winding 98. If under such conditions the rate-of-turn as indicated by gyro 132 is in excess of a prescribed threshold value the winding 99 is energised and switch 95 closed but if the rate-of-turn indication is less than the threshold the circuit 10 will be opened after the delay introduced by relay 16, 34. A pitch gimbal synchro 71 has its rotor winding 73 positioned by a shaft on the pitch axis of gyroscope 40 and its stator windings 77 connected to those 81 of a synchro 68 whose rotor winding 66 is positioned by a pendulum 85. Normally the amplifier 62 energises heater 36 but on the angle between the gyro spin axis and the vertical as given by pendulum 85 becoming excessive the amplifier 62 cuts off power to the heater 36 and switch 18 is opened. In a modification the automatic pilot is only disengaged upon failure of the power to gyro motor 48 or energisation for too short a time to ensure proper erection and circuit 10A is used, circuit 28B replacing circuit 28.
