Title: Vehicle brake control system
IPC: B60T8/72
Filed: 1973-01-12
Abstract: 1383732 Aritiskid braking systems KELSEYHAYES CO 12 Jan 1973 [17 Jan 1972] 1854/73 Heading F2F An antiskid braking system comprises means for providing a signal of magnitude representative of the velocity of one wheel signal generating means providing a control signal having a magnitude which is a preselected proportion of the velocity signal, said signal generating means being responsive to the control signal attaining a predetermined time rate of change for causing the signal to decrease at a selected time rate of change less than the predetermined rate of change whereby the magnitude of the velocity signal and the control signal approach each other, a comparator for comparing the magnitudes of the velocity signal and the control signal and providing an output signal, when the velocity and control signals have attained a predetermined relationship, to cause the brakes to be released by modulating means. A sensor 28 supplies a signal, whose frequency varies with wheel angular velocity, to an integrator circuit 40 which provides an output signal whose amplitude varies with wheel speed. This signal is amplified by an amplifier 42 and transmitted to a clamp reference circuit 43, and thence to amplifiers 47, 49 the output B of amplifier 49 being a proportion of output A of amplifier 47. Signals A and B are fed to a comparator 44 whose output, amplified by an amplifier 54 controls the solenoid 58 of a modulating valve 24. Amplifier 49 is operated on a variable bleed and hold circuit 48 which generates the preprogrammed vehicle control ramp. When signal 6 exceeds signal A an output is generated to operate the valve 24 and relieve brake pressure. If there is failure of the control module 26 the battery of the power supply is connected directly to ground via a fuse which will blow to open the circuit and de-energize the module and permit normal braking. A failure warning light may also be included.

Filed: 1967-01-13
Abstract: 1,176,882. Moulding tyres. RUBBERFABRIEK VREDESTEIN N.V. 13 Jan., 1967 [17 Jan., 1966], No. 1875/67. Heading B5A. A method of moulding a tyre comprises preshaping a tyre carcass with a bladder, introducing a core comprising a number of segments into the bladder, completing shaping of the carcass during closing of the mould, and then injecting outer covering material into the closed mould and then curing the material and carcass. In apparatus for carrying out the method, a press is opened, after a shaping and curing process, to raise upper mould part 15 a short distance. Cylinders 10 are then primed to move core segments 11 upwardly, the lower half of the tyre then being raised from mould part 14, a predetermined pressure of air being maintained in chamber 4 such that plate 18 follows the part 15 upwardly. Thereafter the segments 11 are first withdrawn from bladder 17 by the action of piston and rods 12, 13 and then withdrawn into the position shown in dotdash lines in chamber 4. Plate 18 is then moved further upwardly by plate 22 and pistonrod 21 as the press is opened further to stretch the bladder, Fig. 3. The tyre now being free of the segments and bladder and resting freely on part 14, is removed therefrom. Chamber 4 may be evacuated prior to or during the continued upward movement of plate 18 to facilitate shaping of the bladder to receive a tyre carcass 24. Air under pressure is then introduced into the chamber 4 to flex the bladder into contact with the carcass prior to lowering platen 3 of the press, whereon the closing of the mould in reverse sequence is effected. Curing is effected by heating the core segments and mould parts electrically and by steam respectively and may be effected in the press or in separate apparatus.

Abstract: 224,417. Hoare, C. J., and Allday, N. Jan. 23, 1924. Stud and socket fastenings. - In fastenings wherein a headed stud is engaged in the socket by a spring-pressed claw-carrying member movable longitudinally of the socket, the said member is in the form of a continuous sleeve carrying the claws at the inner end and a knob or cap at the end which protrudes from the cover of the socket, and is directly engaged by the spring. In the form shown in Figs. 1 and 3, the socket-member 6 carries the sliding sleeve 20 with claws 22 at one end and a knob at the other. When the stud 21 is inserted into the socket and the sleeve pushed inwards, the claws travel down the conical shaped part of the plate 25 and engage the stud. Two arms 8 of a spring 7 slide down the inclined slots 12 in the sleeve to press the sleeve into engaging position. When the sleeve is pulled outwards, it first releases the claws from the stud. The knob is attached by forcing its rim into an annular recess 17 in the sleeve. The spring is retained between the cover 9 and the plate 25. In the form shown in Fig. 4, the claw end 32 of the sleeve 30 is enlarged and engages a spiral spring 41 which keeps the sleeve in engaging position. The knob in this case is riveted at 39 to the end of the sleeve and has a cylindrical part 40 engaging over a prolongation 29 of the socket cover for guiding the sleeve.
