Title: Improvements in or relating to wheel brakes for vehicles
IPC: B60T11/04
Filed: 1925-09-18
Abstract: 262,201. Pugh, J. V. Sept. 18, 1925. Force - transmitting mechanism. - In a braking system for a vehicle, the application of power to a pedal causes the front and rear wheel. brakes to be at first applied equally with a rapidly increasing predominance of the braking force on the front brakes, until the force on the back brakes reaches a maximum when about one half the final braking power has been applied, and the force on the back brakes then diminishes until the final braking force is applied to the front wheel brakes only. The brake pedal f<1>, Fig. 4, turns a shaft f on which are mounted a cam f<2> which coacts with a projection h<1> on a shaft carrying levers h<2> operating the front wheel brakes and a cam f<3> which coacts with a projection i<1> on a shaft carrying levers i<2> operating the rear wheel brakes. The cam f<3> is so formed that the levers i<2> are carried through their total range of movement during the first half of the total movement of the pedal f and then returned to the position of rest, and the cam f<2> is so formed that the levers h<2> are moved continuously through the total range of movement of the pedal f. Rods j, k connecting the levers h<2>, i<2> to the front and rear wheel brakes contain resilient devices. The resilient devices in the rods j to the front wheel brakes are capable of a considerably greater deflection than the resilient devices in the rods k to the rear wheel brakes. The resilient devices comprise a spring enclosing one part of the brake rod and bearing on a nut screwed on the end of the rod and on the inturned flange of a tube enclosing the spring, the tube being screwed on the other part of the brake rod. The cams may be duplicated and placed at the ends of the pedal shaft to operate directly on projections on the levers. Cranks may be used in place of cams as shown in Fig. 5 in which the crank e operating a front wheel brake should be nearly at right angles to the rod b<4> which it operates when at its mid position of operation, and the crank e<1> operating a rear wheel brake should be in line with the rod b<5> which it operates when at its mid position. In a construction in which the crank e<1> is on the opposite side to that shown in Fig. 5, this crank is connected to the brakes through a spring device comprising two telescoping tubes having flanges between which is a spring.

Title: Data processing system with improved memory

Abstract: 1,137,784. Memories; computers. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23866/67. Headings G4A and G4C. Sections of a register in a data processing system are loaded from a memory or another source depending on the states of respective zone storage devices. "Information sources", viz. input-output-device controllers and a processor, can each communicate on a priority basis with either of two memory systems, each constituted as follows. 36-bit words in a core memory may consist of six 6-bit characters, or four 9-bit characters, or may consist of either. Each character position in a memory register is set with the correspondingly-positioned character in a word from the core memory addressed by the "information source" or from the correspondingly - positioned character in a word supplied by the "information source", depending on the settings of one or more corresponding flip-flops of a zone register controlled by the information source. The contents of the memory register are rewritten into the core memory and sent to the "information source". If the 36-bit word can only have 6-bit characters six zone flip-flops are needed, one for each character position. Similarly four zone flip-flops are needed, one for each character position. Similarly four zone flip-flops are needed in the case of 9-bit characters. If either character size is possible, eight zone flip-flops are needed. Double-length words, read-out in two stages, may be used.
