Title: Improvements in or relating to the lamination of transparent coverings onto copy sheets
IPC: B44C1/14
Filed: 1962-11-22
Abstract: 1,015,362. Laminating. W. RITZERFELD & G. RITZERFELD. Nov. 22, 1962 [Dec. 5, 1961; Dec. 8, 1961; March 19, 1962], No. 44158/62. Heading B5N. A method of laminating a transparent covering to a copy sheet comprises feeding a sheet of transparent covering material having an adhesive coating and the copy sheet between co-operating elements of a duplicating machine, the copy sheet having been moistened with a solvent for the adhesive coating by means of a moistening device of the duplicating machine, and pressing the copy sheet and the covering sheet together by means of the printing elements of the duplicating machine. Preferably the adhesive is a material soluble in alcohol. Both the adhesive coating and the copy sheet may be moistened before pressing together. The transparent sheet may include a coloured substance absorbent of ultra-violet light. In one example of a suitable duplicating machine, a printed copy sheet 26 is supported by a feed table 27 and is fed via rollers 6, 9 to a guide plate 8 where its leading end engages the leading end of the covering sheet 37 supported by feed table 32. A felt member 11 mounted on a carrier member 12 which dips into the solvent 33, is pressed against roller 9 which moistens the copy sheet 26. Movement of the copy sheet by the rollers causes it and the covering sheet 37 to move to the bight between the printing elements 1 and 4, where the sheets are laminated together. In an alternative embodiment, the covering sheet may be mounted on the printing drum 1. The felt member 11 is extended to contact the printing drum so that both the covering sheet and the copy sheet are moistened by the solvent. Lamination may also be effected with a flat bed duplicating machine (Fig. 5, not shown).

Abstract: 1,236,352. Toy railway vehicle couplings. C. K. EDWARDS and L. D. EDWARDS. 5 Sept., 1969 [13 March, 1969], No. 44174/69. Heading A6S. An automatic coupling device for toy railway vehicles, comprises a spring housing 43 having a chamber 44 with a rear wall 46 having a spring retaining projection 48. The forward, outer wall 50 of the housing has a slot 51 through which the two superposed shanks 54 and 60, project. The hook comprises a knuckle 52 on a shank 54, the knuckle having a hook portion 57 to prevent uncoupling on curves. The shank 54 also has a terminal crossbar 56 at its inner end. The retainer lip 58 is carried on a shank 60 which also has an inner terminal cross bar 62-64, the arm 64 being angled to facilitate easier pivoting in a clockwise direction. The cross-bars of shanks 54 and 60 each have a spring retaining means 66 in the form of a half cone, forming a full cone when the two shanks are superposed. The spring 18 is of the helical compression type is retained over projection 48 and projections 64 of the shanks, and maintains the latter pressing against the inside surface of wall 50, and also normally maintains a constant separation be tweenl lip 58 and hook 57. A soft iron magnetic detector is attached to shank 54 and passes through an elongate hole 78 in shank 60. The shanks are maintained in the housing and prevented from moving vertically by retainer 13 and clip 68. Detector 24 causes lateral movement of the hook, in a clockwise direction, when the vehicle is reversed over a magnet transverse to the track thus widening the gap between hook 57 and lip 58, so that when the pulling vehicle now moves forward, the hooks may be separated. The operation of the coupling in this respect is described more fully in the Spceification, with rspect to Figs. 4-7 (not shown).

Title: Push-button key assembly
IPC: H04M1/23
Filed: 1971-09-24
Abstract: 1326530 Substation apparatus INTERNATIONAL STANDARD ELECTRIC CORP 24 Sept 1971 [24 Sept 1970] 44646/71 Heading H4K [Also in Division H1] In a push-button key assembly, key guides project upwardly from a top cover of a housing and each contain means to respond to the depression of the associated key and to displace horizontally a corresponding slider, each slider causing at least one permanent magnet to rotate operating at least one reed contact unit, displacement of any slider also causing a common slider to be displaced, which via a common magnet operates a common changeover switch arrangement. Two arrangements for pushbutton telephone dialling are described. As shown key guides such as 4 project upwardly from the top cover 2 of the housing. Each key guide is integral with the plastics top cover and carries a lever 8 integral with the guide at a point 6 so as to form a hinge. When the associated key is depressed the lever pivots downwardly about the hinge against the action of a spring positioned immediately below the hinge and a nose 9 on the lever displaces a corresponding slider 10 to the right. Lugs such as 21 on the slider engage generally trapezoidal sections of a combination of transverse shafts and cause them to rotate through 90 degrees as shown by the shaft immediately below lug 21. Each shaft carries a permanent magnet which when the shaft is rotated actuates a sealed reed contact unit positioned below the shaft. Any slider when displaced engages the cross-piece 12 of a T- shaped common slider arranged to move in the same direction as the other sliders and coupled to an arcuately movable magnet carrier pivoted about a shaft 17, by means of a spring such that as the point at which the spring is connected to the slider passes the axis of the shaft 17 the arcuately movable member snaps to the position shown moving the magnet it carries from a position adjacent a reed contact unit 16 to a position adjacent a similar unit at the other end of the arc. The common slider is biased towards its original position such that when the depressed key is released the common slider and the slider 10 both return to their original positions. The arcuate member snaps back to its original position before lugs on the common slider turn the transverse magnet carrying shafts to their original positions. The base of the set is closed by a circuit board using printed or punched conductors and extends beyond the housing to allow connection to a cable and the mounting of external components such as diodes.

Title: Improvements in or relating to Multiplexing Circuits
IPC: H04J3/24
Filed: 1967-10-02
Abstract: 1,199,023. Computer input/output. INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1967 [26 Oct., 1966], No. 44712/67. Heading G4A. A communication multiplexing circuit comprises a common receiving terminal with a plurality of data stations connected to it, and a plurality of respective control circuits associated with the data stations and interconnected independently of the common receiving terminal to form a loop oscillator for repeatedly and sequentially scanning the data stations, the arrangement being such that data flow between a particular data station and the terminal can only be initiated while that station is being scanned, scanning being halted during such data flow and resumed when the data flow ceases. Input/Output stations communicate with a computer over a common data bus (or radio or light may be used). When a station requires to communicate with the computer, either because it has received its own address from the computer over the bus or of its own initiative, it applies a request signal to a control circuit respective to the station. The control circuits are permanently connected in a loop which comprises a delay in each control circuit and a single inverter. Positive-going and negativegoing wavefronts pass around the loop alternately, each wavefront being converted into the next by the inverter, the loop thus constituting a loop oscillator. When a negativegoing wavefront arrives at the control circuit which is receiving the request signal, the corresponding station is signalled that communication may commence and the negative-going wavefront is overridden. At the close of communication, the request signal ceases and the negative-going wavefront continues around the loop. A plurality of loops with a common portion may be provided, there being a number of control circuits in each non-common loop portion. A counter driven by positive-going wavefronts in the common portion gates the wavefronts to the non-common portions in turn, some non-common portions receiving more wavefronts than others (and therefore a greater share of the total time) by ORing some signals from the counter together in different-sized groups before use for gating. Specification 1,062,225 is referred to for details not peculiar to the invention.

Abstract: 1529566 "Watermarked" magnetic tape EMI Ltd 2 Oct 1975 [16 Oct 1974 21 Jan 1975] 44747/74 and 2546/75 Heading G5R Magnetic tape in which the preferred axes of magnetization of the particles forming the magnetic layer are normally aligned in the direction of tape length, is "watermarked" during manufacture by altering the orientation of the preferred axes at positions along the length of the tape. The magnetic axis of the particles is changed through an angle of about 25 degrees only whereby the resultant change in remanence at these positions is sufficiently low not to interfere with the playback of a signal recorded on the tape yet is of sufficient level to be detected. Where the "watermarked" tape has a number of tracks one of these can be used for detection purposes only or where the tape is single track an information free part of the track can be magnetized with a unidirectional field so that the watermark signal can be detected.
Patent GB-447767-A (GB)
Abstract: 447,767. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool, TAYLOR, R., 30, Oulton Road, Wavertree, Liverpool, and BAKER, G. T., Blackbrook, Caerphilly, Glamorgan. Nov. 23, 1934, No. 33752. [Class 40 (iv)] In a double - hunting group selector, the test relays HA, HB energize before the hunting movement begins and are held by earth on the test terminals until an idle line is found or until the selector reaches its eleventh position, when one or other falls back and opens the driving circuit. If two idle lines are found simultaneously, both relays fall back but a fresh circuit is completed for one of them, so that one line is given preference. The dialling relay C, which relapses to initiate the hunting movement, reoperates when either of the test relays falls back to switch through the connection and to control release. The invention is applied to a selector of the kind described in Specification 391,123 which continues its rotary movement upon release and then drops and rotates back to normal. Upon seizure, line, release and dialling relays A, B, C energize and impulses are repeated to vertical magnet VM in series with C. At the first step, relays HA, HB operate over their right-hand windings and shortcircuit the energizing winding of C, so that it relapses at the end of the impulse train and completes a self-interrupting circuit for the rotary magnet RM. Relays HB, HA are held over their right-hand windings to earth via test wipers P1, P2 as long as busy lines are encountered, and between terminals are held over their left-hand windings in parallel with RM. If wiper P1 finds an idle line, HB falls back, cutting the drive, and C reoperates, due to the removal of its short-circuit, and closes a fresh circuit for HA over its middle winding, this relay having been disconnected by HB from wiper P2. Relay C switches through to the upper set of wipers, and A, B relapse. If wiper P2 finds an idle line, that engaged by P1 being busy, HA falls back, cutting the drive and holding HB over its middle winding, and C reoperates and switches through to the lower set of wipers. If all the lines of the level are busy, 11th step springs S become operated, HB falls back so that C switches through to the upper set of wipers over which busy tone and flash are supplied via line relay A. Upon release of the connection, HA or HB falls back and disconnects C, which completes the circuit of rotary magnet RM to rotate the wipers clear of the banks, after which they drop and return to normal under spring tension. The selector is unguarded momentarily until C relapses to release the preceding switches.
