Title: Improvements in or relating to Edge-Wheel Type Rotary Electrical Switches
Inventor: GLASS JERZY GEORGE
IPC: H01H9/16
Filed: 1967-06-20
Abstract: 1,154,968. Mechanical switches. TELEPHONE MFG. CO. Ltd. 29 May, 1968 [20 June, 1967], No. 28486/67. Heading H1N. A plurality of thumb-wheel switches to be fitted in an aperture in a panel 13 are mutually aligned by providing each switch with lateral extensions 6 and 7 of top and bottom walls 8 and 9, respectively, and grooves 17 and 18 on the opposite side which mate with the corresponding extensions of the adjacent switch. The switches are retained in the panel by plugging rearwardly extending edges of side plates (4, Fig. 1, not shown), which are formed as printed-circuit boards, into standard edge-connector terminal sockets (not shown). Each switch has individual pivots providing a key extension 21 at one side and a key-way slot (19, Fig. 1, not shown) at the other side, whereby the switches may be operated conjointly. If independent actuation is desired the key 21 may be broken off. If key 21 is not broken off, a thin portion 22 of the front moulding of the adjacent switch is pushed out to provide a small slot so that individual switches may in either case be readily removed from the assembly by sliding forwards when the key-way slot is orientated parallel to the grooves 17 and 18.

Abstract: 461,204. Wireless signalling. POSCHL, O., DIETRICH, A., and HABIG, P. Oct. 16, 1935, No. 28581. Convention date, Oct. 17, 1934. [Class 40 (v)] Ultra - short - wave inter - communication between two or more stations such as A, B, Fig. 1, which are not within " optical " range, is effected through a relay station C. Signals from A are received at C and demodulated at D1, Fig. 2, and the rectified signals are used to modulate at M the outgoing carrierwave from the transmitter T. 'Similarly, signals from B are demodulated at D2 and relayed by the transmitter T. The same dipole can be used for transmission and reception.

Title: Improvements in wheels with portable track members
IPC: B60B15/18
Filed: 1924-11-28
Abstract: 238,431. Mamessier, H. Nov. 28, 1924. Endless-track vehicles.-A portable-track wheel comprises radial rods a sliding in cylinders b under pneumatic or other checking action and connected by ball-joints d to shoes f having part-spherical surfaces engaging the ground either directly or through members h. The edge of the spherical face f<2> of each shoe bears against the inner cycloidal face of the side of the member h. In the construction shown each rod a is formed with a piston a' having a non-return valve a<2>, so that as the rod is pushed inwards under load air is compressed in the cylinder b. When the rod is free of load it is pushed outwards again by a spring p assisted to some extent by air pressure, while air may pass from the spring cylinder b<1> to the cylinder b through the valve a<2>. All the cylinders b communicate with each other by an annular conduit m and excessive pressure is prevented by an escape valve o. Hydraulic checking means may be provided instead of pneumatic. A single or a double row of rods and feet may be used.

Title: Keyed gain control systems in television receivers
IPC: H04N5/50
Filed: 1963-07-19
Abstract: 1,042,348. Automatic gain control. STANDARD TELEPHONES & CABLES Ltd. July 19, 1963 [July 21, 1962], No. 28629/63. Heading H3Q. In a television automatic gain control arrangement for positively modulated signals, the negativegoing video signal from the video detector 1 is passed over an R.C. coupling network 2, 3 to a phasereverser 5, the output of which is combined with the D.C. component of the video signal which is obtained by means of an R.C. filter network R, R<SP>1</SP>, C and does not undergo reversal of sign. The combined signal is applied to the grid of an amplifier 6 having as anode load resistor 7. The positive-going waveform appearing at the anode of valve 6 is applied to the grid of a gate valve 9, to the anode of which are applied line fly-back pulses from transformer 11, via capacitor 12. The negative-going pulses at the anode of valve 9 are smoothed by R.C. filter network 13 and constitute the gain control voltage. By including the D.C. component of the video signal in the waveform controlling the valve G and hence the gate valve 9, the arrangement prevents the loss of control which normally occurs with an A.G.C. circuit of the gated type, e.g. on switching on, when the video amplifier is otherwise overloaded.

The photosensitive layer is first uniformly charged either +ve or -ve, then subjected to a corona discharge which is either A.C. or of opposite polarity D.C. to the original charge immediately before or during exposure to the laser beam, and finally exposed to uniform radiation. The resultant electrostatic latent image is developed with a toner and the toner image transferred to copy paper.

Abstract: 1429501 Photographic print-out processes XEROX CORP 18 June 1973 [21 June 1972] 28833/73 Heading G2C [Also in Division C3] Negative coloured print-out images are produced by imagewise exposing a material containing an aromatic hydroxy compound and an inorganic or aliphatic nitrite in non-acidic conditions to excite the hydroxy compound and initiate the colourforming reaction. The image may be stabilized by removing the reactant(s) from the unexposed areas by solvent or by heat. The reactants may be coated as a layer (with or without a binder) on a support or may be used with a binder as a self supporting material. The material may also contain a metal salt or a primary aromatic amine to produce a deeper coloured image. Alternatively, the primary amino group may be present on the aromatic hydroxy compound. In the Examples, a paper (optionally sized with starch anthrinilate) or Al support is coated with (a) 2-naphthol, 8-amino- 1-naphthol-3, 6-di-sulphonic acid sodium salt or 2- naphthol-6-sodium sulphonate (b) sodium or isoamyl nitrite and optionally (c) polyvinyl pyrrolidone, imagewise exposed and fixed by washing with water, heating or placing a polyester layer over the image.

Title: Cable-sheathing press
IPC: B21C23/30
Filed: 1957-09-13
Abstract: 821,909. Extruding. HYDRAULIK G.m.b.H. Sept. 13, 1957 [Sept. 14, 1956], No. 28894/57. Class 83 (4). A cable sheathing extrusion press has a single receiver 1 adapted to be cut-off from the feed duct 12, 13 leading to the extrusion die, and a storage device consisting of an auxiliary ram 1a and cylinder 9 is disposed in said duct and is charged with the extrusion material from the receiver during the working stroke of the main ram 3, and upon withdrawal of the latter for re-charging the receiver, extrusion is continued from the storage device. In one embodiment the receiver 1 is stationary and has an outlet ball valve 6 which closes during retraction of the main ram 3. The latter is actuated by a piston 4 in a main cylinder 5. The auxiliary ram 1a is integral with the receiver and operates in a cylinder 9 formed in a member 11 attached to or integral with the press-head 10 through which the cable 14 passes. The press-head is supported on an hydraulic piston 15 working in a cylinder 16 supplied with pressure water through pipe 22 and having an outlet 21 controlled by a throttle valve 20. During extrusion of an ingot in the receiver, the piston 10 is forced into the cylinder 16 whereby the storage cylinder 9 is filled and upon subsequent withdrawal of ram 3 pressure water is admitted to cylinder 16 which raises the presshead and member 11; valve 6 is thereby closed and extrusion continues from cylinder 9. In another embodiment, Figs. 3, 4 (not shown), the press-head is stationary and the receiver 1 carrying the auxiliary ram 1a is movable by hydraulic pressure. Instead of the valve 6 a conical feed duct tapering towards the extrusion die may be used to prevent back flow of material during operation of the auxiliary ram.

The brake may be operated by a foot or hand control connected to either end of a compensating bar connected to a sliding block 19 in a connection 18. Movement of either control moves the piston 15, to which the connection 18 is attached by an extension 17 and connects the brake cylinders 1 to vacuum by pipes 12, 40.
