Abstract: 1,267,220. Controlling wheel-spin. DAIMLER-BENZ A.G. 31 Oct., 1969 [2 Nov., 1968], No. 53496/69. Heading B7H. Spinning of the driven wheels of a motor vehicle is controlled by means which detect a difference in the speed of rotation of the driven and non-driven wheels and vary the driving torque applied to the driven wheels accordingly. Associated with each driven wheel 3, 4 and non- driven wheel 1, 2 is an electric generator 5, 6, 7, 8 which produces a voltage proportional to the wheel speed. The generators 5, 7 and 6, 8 on each side of the vehicle are connected to a differential amplifier 9, 10, the generators 7, 8 through voltage dividers 11, 12 which reduce the voltage therefrom sufficiently to permit a maximum wheel-spin of 15%. When the wheelspin exceeds this value the respective amplifier 9, 10 produces a signal which causes braking of the slipping wheel or a reduction of engine torque. As shown, both amplifiers 9, 10 are connected to a combination element 21 which transmits a signal to actuating means 16 for interrupting the engine ignition or reducing the fuel supply only when receiving input signals from both amplifiers, and each amplifier 9, 10 is also connected to a respective combination element 22 connected to actuating means 17, 18 for a valve 19 which connects a pressure source to a brake 20, the elements 22 being blocked when there is an output signal from the element 21 so that slipping of one wheel causes application of the appropriate brake and slipping of both wheels causes a reduction in the engine torque but no braking. To avoid repeated brake applications it may be arranged that once a brake has been applied it is not released until the wheel-spin has been reduced to a predetermined low limit value of 5%. Communication between the brakes and a pedal-actuated master cylinder providing for normal brake control is cut-off when the brakes are applied to prevent wheel-spin. During normal applications of the brakes by means of the pedal, braking in response to wheel-spin is automatically prevented.

The pressure sensor comprises a cylinder 14 which is fixed to a casing 6, 7 defining the space, and a piston 15 which is moved by the pressure of water entering through holes 16 to compress spring 17. This movement releases plunger 22, 25 from a position locked to cylinder 14 so that the gas source 24 is punctured. The pressure of released gas forces the plunger to move against the pressure of spring 33 to a position where locking balls 21 are released, allowing a tube 10 to move. Tube 10 is then ejected by gas pressure from the casing, taking with it the recorder container 45 and the cover 3, 8. The container holds a lightweight recycling flight data recorder and a battery powered radio beacon 47 and flashing light 49. The apparatus is fitted in the tailplane of an aircraft within a fairing 1.

Abstract: 1294932 Rotary positive-displacement fluidmotors EATON CORP 27 Feb 1970 [7 Nov 1969] 9746/70 Heading F1F In a reversible hydraulic-motor of the n and n+1 lobe type a rotary valve-member 14 in a housing end-cap 11 controls the flow of working fluid between inlet and outlet openings 12, 13 and cells 51 of a gerotor set 22 comprising a planetary rotor 48 meshing with rolls 47 in a fixed plate 44, the member 14 and rotor being coupled to an output shaft 36 by splined members 59, 64. The member 14 has pressure-balancing dummy-ports 54 between ports 58 that co-operate with openings 53 in a fixed valve-plate 18. Springs 76 on pins 75 on a non-rotary axially-movable ring 70 urge the member 14 towards the plate 18. The pins 75 engage with openings 93, which inter-connect grooves 84, 86, 88 in the face of the ring abutting the member 14. Notches 82, 92 and grooves 81, 90 allow the working fluid to assist the springs 76 in pressing the member 14 towards the plate 18. To lubricate the mutually abutting faces of the member 14 and the ring 70, bearings 37, 39, 40, 41 and the members 59, 64 a proportion of the working fluid flows from the inlet opening 12 or 13 into passages 101 by way of a notch 100 in the member 14 and the grooves 84, 86, 88. Fluid that has passed between the splines of the members 59, 64 reaches said bearings through openings 102, 103. Fluid returns from the bearings to the outlet opening 13 or 12 by way of passages 106...110 and either a bore 112 containing a spring-loaded ball 111 to act as a non- return valve, and a passage 115, or a branch passage 115, or a branch passage 117 controlled by a spring-loaded ball, and a passage (122), Fig.9 (not shown). The pressure-differential between the outlet opening and the grooves 84, 86, 88 is insufficient to allow fluid to flow to this opening from these grooves by way of the notch 100. Leakage of fluid into spaces behind the ring 70 is prevented by resilient rings 94, 97 made of P.T.F.E.
