Filed: 1971-08-03
Abstract: 1361619 Aritiskid braking systems KELSEY HAYES CO 3 Aug 1971 [3 Aug 1970] 36420/71 Heading F2F An antiskid braking system comprises means for sensing the acceleration of the wheel and providing a first signal representative of wheel acceleration or deceleration, means responsive to a preselected magnitude of the first signal for providing an error signal having a magnitude determined by the difference between the first signal and said preselected magnitude and brake control means for maintaining the magnitude of the first signal proximate to the preselected valve so that the wheel will decelerate at a rate close to a preselected magnitude. Signals from rear wheel sensors 48 are fed to a tachometer circuit 53 which integrates the signals to provide a D.C. output signal w, the magnitude of which is indicative of the combined rear wheel speeds, and which is fed to a slip threshold circuit 56 which in turn generates an adjusted threshold wheel velocity signal wa. This signal is compared with a simulated vehicle velocity signal Va by a comparator circuit 64 which provides an output slip signal x when Va exceeds wa, the signal Va being obtained from signal w transmitted to a ramp circuit 54 comprising a capacitor charged through a diode to a potential equal to that of signal w. When no braking occurs this potential also indicates actual vehicle velocity Vv. The circuit 54 has a discharge circuit with a time constant indicative of a selected vehicle deceleration rate. When the brakes are applied and the wheel speed signal w drops below the magnitude of the charge on the capacitor the latter will start to discharge at a selected rate and provide an output signal Va having a magnitude approximating vehicle velocity. The hydraulic system includes valves 252r, 252f for controlling pressure to the rear brakes and front brakes respectively responsive to signals from the control unit as in Specification 1,361,620. The system is arranged to provide a controlled deceleration rate of 3.5 g. the pressure being relieved by some 30% for an incipient skid condition on a surface having a high coefficient of friction.

Abstract: 1,273,734. Lubricating. RICARDO & CO. ENGS. (1927) Ltd. 22 July, 1969 [31 July, 1968], No. 36531/68. Heading F2A. [Also in Division F1] A small-end bearing of a reciprocating piston mechanism is fed with lubricant by a singleacting pump actuated by the angular swing of the connecting-rod relative to the piston, pumping being effected when the connecting-rod is moving towards its mid-angular position. In an embodiment a small-end bearing 12, Fig. 1A, is lubricated by means of a pump 13 which is carried on a connecting-rod 11 and has a plunger 15 connected by a link 17 to an arm 19 mounted on a piston 10 of the reciprocating piston mechanism. As shown, the plunger 15 is in its innermost position in its casing 14 whereas the plunger 15, Fig. 1B, is shown in its suction position and the connecting rod is no longer in its mid-angular position. In modifications a pump 13<SP>1</SP> is carried by a piston 10<SP>1</SP>, Fig. 2A (not shown) and the plunger is activated by means of cams 30, 31, Fig. 3A, and a spring 33. In another embodiment a bearing R, Fig. 5, is lubricated by means of a pump A which is attached to a lug B of a connecting-rod C and which has a plunger D driven, via a crosshead member E, by a hinged link-rod F having an end hinged to a pin H carried on a bracket J attached to a piston body K. Lubricant is supplied to the pump A via a hole C1 in the connecting-rod C, an annular groove C2, around a gudgeon pin L, passages M, M, and a port N, which is uncovered by the top edge of the plunger D at the bottom of its outstroke. Thus the plunger casing is filled with lubricant which is forced by the plunger D through a non-return valve P to the bearing R. A groove D1 and a passage D2 are provided in the plunger D, the groove D1 registering with the port N, before the plunger reaches its innermost position, in order to prevent overloading of the pump.
