Title: Register mechanisms
Inventor: DEACON LIONEL OAKLEY
IPC: G06M1/14
Filed: 1962-12-17
Abstract: 973,380. Cam mechanism; utilizing inertia to obtain movements in machinery. CHAMBERLAIN & HOOKHAM Ltd. Dec. 12, 1963 [Dec. 17, 1962], No. 47422/62. Headings F2K and F2X. In a register mechanism, each complete rotation of a drum 10 is effective to advance a second drum 11 through a predetermined angle, e.g. <SP>1</SP>/ 10  revolution, by means of cam mechanism comprising a stepped cam 15 secured to drum 10, a grooved cam formed by inner and outer cam surfaces 18, 19 formed on drum 11, and a pivoted arm 14 disposed between the drums 10, 11 and carrying a pin 16 on one side, which is adapted to engage cam 15, and carrying a pin 17 on the opposite side, which is adapted to engage the cam groove on drum 11. Cam surfaces 18, 19 comprise tooth-like projections, the crest of each projection on the inner cam surface 18 being slightly in advance of the root of the adjacent projection on the outer cam surface 19. As cam 15 rotates, its engagement with pin 16 causes outward movement of arm 14. Towards the end of the movement pin 17 abuts a portion 19c of cam 19 which causes the drum 11 to be angularly displaced slightly. When pin 16 passes over the stepped portion of cam 15, arm 14 drops, under its own weight, and pin 17 acts on a flank 18b of cam 18 to advance the drum 11 through <SP>1</SP>/ 10  revolution. The arm 14 may be biased by a light spiral spring and may be replaced by a plunger. The inner cam surface may have lost motion with respect to the outer cam surface and spring biasing means may be provided between them.

Abstract: 1,200,464. Bumpers; collapsible steering columns. NISSAN JIDOSHA K.K. 19 Oct., 1967 [24 Nov., ]966], No. 47581/67. Headings B7H and B7J. [Also in Division F2] In an impact absorbing means for a vehicle, a bellows or corrugated tubular member 1 is provided with axially spaced projections 2, each of the projections having a plurality of slits 5 extending longitudinally and substantially parallel to each other on the periphery of the projection, so that impact energy is absorbed by deformation of the corrugated tubular member when an axial compressive force is applied. As shown in Fig. 5, the invention is applied to a steering column assembly wherein the steering wheel 12 is secured to an upper column shaft 13 provided with a hollow space 17 having sufficient depth to accommodate the splined end 15 of a lower steering column shaft 16 connected to the steering box 28. Upon sudden impact the steering wheel will be forced downwardly to cause relative axial displacement between the upper steering column shaft 13 and the lower steering column shaft 16 to deform the impact absorbing member 1 and dissipate the kinetic energy. Fig. 6 shows an alternative embodiment wherein the impact absorbing members 40, 41 are inserted between the forward and/or rear portion 42 of the vehicle and a bumper 43. Reference has been directed by the Comptroller to Specification 1,127,376.

Abstract: 1,111,436. Moulding plastic materials CIBA Ltd. 25 Nov., 1965 [26 Nov., 1964], No. 50208/65. Heading B5A. A method of moulding articles, e.g. electrical insulators, bushings or housings for electrical fittings, from a resin mixture having a hardener and a particulate filler in which most of the particles have a grain size less than 160Á includes the steps of compressing the mixture in a mould, and when the compressed body has hardened sufficiently it is impregnated with a liquid mixture of synthetic resin and then cured. Before hardening and impregnation the body may be removed from the mould. The proportion of filler in the compressed mixture may lie between 65 and 98%, and may comprise aluminium oxide trihydrate, calcite, quartz flour or mica powder or mixtures thereof. Examples of resins used in the compressed mixture include vinyl chloride, polyesters and epoxy resins, and a similar or different resin may comprise the impregnant. A composite article may be formed by moulding and hardening the individual parts separately, and then assembling them and then impregnating and curing the assembly. Terminals, electrodes and capacitor coatings may be embedded in the moulded article. A bushing having capacitor coatings, Fig. 8, not shown, is formed by moulding interfitting concentric tubes (7, 8, 9) separately, the tubes having cylindrical capacitor coatings (11, 12), assembling the tubes one within the other, inserting a conductor (10) in the innermost tube, and impregnating and curing the assembly. The impregnation is effected in a container (13), Fig. 10, not shown, to which the impregnant is supplied through a passage (14), a cover (15) closing the container and being connected to a vacuum source.

In other arrangements, demodulation is effected by an auxiliary anode in one or both of the valves V1, V2. In the arrangement shown in Fig. 5, each valve has two auxiliary anodes, one pair A operating in push-pull to produce demodulated signals across a resistance R1 which are then fed to an amplifier V5, the other pair A1 providing a direct-current bias potential across resistance R2 which is employed for automatic volume control. The resistance R2 is connected to a point negative with respect to the cathodes, the resistance R3 providing a variable delay voltage.

A startup unit 70 for two steam generators No. 1 and No. 2 and which may also be used to start other generators in a steam generating plant operates as follows:- The generators comprise first heating sections 16, 26 with recirculating pump 18 and second superheating sections 30, 32, the two sections being separated by stop valves 72. Feedwater is supplied by pumps 10, 12 from the turbine condenser 48. During the initial phase of the startup of No. 1 generator valves 76, 78 of No. 2 are closed and the following numerals refer to No. 1 generator only. Valves 72, BTB and BT are closed and fluid passes from the first heating section via open valve 76, conduit 58 and valve BE to a separator 60, water being returned to the feedwater supply via valve WD and steam passes through valve SA, conduit 62, open valve 78 to the superheaters 30, 32, to initially load the turbine 38. Steam pressure control now transferred from the BE valve to the throttling valve BTB. The SA valve closes when the steam pressure in section 30 passed through BTB valve exceeds pressure in the separator. Turbine loading proceeds by increasing boiler output and with the turbine valves 36 set at a preselected minimum fixed opening the BTB valve is opened until the pressure drop becomes less than the critical valve, the BT valve is then gradually opened- When the boiler throttling valves BTB, BT are fully open, loading proceeds by turbine valves 36 and valve 72 may be opened and valves 76, 78 closed. The startup unit may then be used to start No. 2 or another generator on the plant in the same manner.
