Title: A communication switching system
Inventor: BRILEY BRUCE EDWIN
IPC: H04Q3/54
Filed: 1969-06-05
Abstract: 1,270,827. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. 5 June, 1969 [11 June, 1968], No. 28441/69. Heading H4K. In a telecommunication system, dial pulse information from a progressive exchange, e.g. step by step, can be sent to an exchange which stores the information prior to using it, e.g. No. 1 ESS, by providing on each trunk line a network which delays all the incoming pulses by a predetermined time. An off-hook condition at an originating office OR is sensed by trunk scanner S1 and causes central control CC to cause the line to be connected to an idle dial pulse receiver DPR through trunk link network TLN and junction WJ. If the OR is an electronic exchange, CC arranges for the incoming trunk circuit ITCI to be put into a by-pass condition and a ready signal sent to the originating office. The ferrod scanner is maintained in an energized state while the DPR is detecting dial pulses and storing them in the call store CS. When the number is complete, the central control CC acts on the information to set up the necessary conditions. In the case where the OR is of the step-bystep type the dial pulses are delayed at the incoming trunk circuit ITCI for sufficient time to ensure that the output of the trunk circuit is connected to the dial pulse receiver. As shown in Fig. 3, a dial pulse relay P applies a signal to the C or S input of the first stage of a shift register STG 1-n which is advanced by applying pulses from oscillator OSC 1 to the toggle input 1 of the register. The delay time is determined by the number of register stages and the shifting frequency used and since the time required to make the necessary connections depends on the traffic load of the exchange, a second oscillator OSC2 having a lower frequency output may replace oscillator OSC1. The output from the multistage register is switched on by transistor TR and the pulses pass to the DPR from the output of ITCI to set up a call connection in the usual way.

Title: Friction welding
IPC: B23K20/12
Filed: 1975-05-14
Abstract: 1481215 Joining glass CLARKE CHAPMAN Ltd 14 May 1975 [27 June 1974] 28480/74 Heading ClM [Also in Divisions B3 and B5] A method of friction welding in which two workpieces 10, 12 are pressed together and orbital translatory motion is applied to both workpieces in the same rotary sense, and preferably at the same speed, to generate heat for welding. When the workpieces are ready for welding either the amplitudes of the orbital motions are reduced (Fig. 2, not shown), the phase difference between the motions is reduced (Fig. 3, not shown), the motions are reduced in speed, or where the orbital motions occur about spaced axes the distance between the axes are reduced and the amplitudes or the phase differences are/is reduced in order that the workpieces are arranged in a required alignment, and then weld pressure can be applied. The orbital motions may be about the same axes (e.g. 20, Fig. 1), or different axes, the orbits being either circular or elliptical. In apparatus for performing the method two workholders 218, 232, mounted on two eccentrics 216, 230 and held from rotating by restraints 220, 234 are translated by two motors one in a fixed head 202 the other in a sliding head 204 the phase difference on being maintained and adjusted by a shaft 206 and in gear system 20. The shaft 206, geared to the motor 204, is connected to a planet gear carrier 240 carrying two planet gears 242, 244 which mesh with internal teeth of a fixed ring gear 246 and a sun gear 248. A shaft 210, geared to the motor 202, is connected to a planet gear carrier 250 having planet gears 252, 254 meshing with a rotatable ring gear 256 and the sun gear 248. If the ring gear 256 is fixed during operation then the two workholders will orbit at a constant phase difference, however the ring gear 256 is rotated then the phase difference can be made to approach zero, at which time welding can be effected. In an alternative (Fig. 9, not shown), the workholders are mounted on two in-phase eccentrics, no restraint 220, 234 being required. A single motor may be connected to shaft 206 instead of using two separate motors. The sliding head 204 may be moved by a hydraulic ram. The method and apparatus may be applied to joining different or the same materials, the materials being metals, plastics, glass or ceramics. Both heads may be slidably mounted on the base.
