Patent GB-729449-A (GB)
Title: Method of forming composite metal coatings on refractory metal
IPC: C23C8/64
Filed: 1952-03-21
Abstract: A process for producing a carbide layer on a core of refractory metal comprises applying a layer of a hydride of a second refractory material, firing to convert the hydride to a refractory coating, applying a layer of carbon onto the coating and firing to produce a carbide of the interface portions of the base and coating.  The process is applicable to the production of a non-emissive electrode, in which case the carbide acts as a barrier layer onto which a non-emissive substance such as carbon or platinum may be applied. Suitable base metals are tantalum, columbrium, molybdenum, tungsten and their alloys; suitable hydrides are. those of zirconium, silicon and tantalum.  Firing temperatures of 1400-2000 DEG  C. are referred to, and the coating with hydride is preferably effected by cataphoresis. Specification 660,076 is referred to.

Title: Improvements in or relating to registering methods employed in photo-mechanical colour printing
IPC: G03F3/04
Filed: 1931-03-10
Abstract: 374,878. Photomechanical printing- surfaces. BRESLAUER, M., 45, Fichtestrasse, Leipsic, Germany. March 10, 1931, No. 7411. Drawings to Specification. [Class 98 (ii).] In the preparation of colour printing surfaces, registration of the colour component records, which are to be photographically reproduced on the printing surfaces, is facilitated by the employment of mounting plates coated with bichromated colloid upon which contact prints have been made from a selected colour component record, preferably that showing the greatest number of characteristic features of the original, and dyeing the prints with a dyestuff offering little resistance to the passage of actinic rays. The prints may he either negatives or diapositives. Negative prints may be prepared from an intermediate print on a glass plate coated with a bichromated colloid, the print being dyed with a dyestuff resisting the passage of light through the dyed parts of the plate. Diapositive prints may be prepared directly from the negative colour component record, laterally inverted to ensure lateral inversion of the images on the final mounting plates. Supplementary register marks may be provided on the original for use in addition to the image of the selected colour component record.

Title: Improvements in or relating to mechanically interlocked push-button electric switches
Inventor: SIMPSON ARTHUR IAN FORBES
IPC: H01H63/22
Filed: 1957-03-08
Abstract: 821,474. Keyboard switches. MODERN TELEPHONES (GREAT BRITAIN) Ltd. March 10, 1958 [March 8, 1957], No. 7787/57. Class 38 (5). A set of mechanically interlocked latching push-buttons 11 are arranged in a circle around the axis of a disc-like latching member 14 which has projections 18 extending between the rectangular-section shafts 19 of buttons 11. The member 14 is spring-loaded to tend to rotate in the direction of the arrow A, and the projections 18 engage cam projections 32 on the shafts 19 of depressed buttons, such as 40 in Fig. 3. Depression of an unoperated button, such as 41, normally moves the member 14 to unlatch a button such as 40, but to ensure this action each shaft 19 is provided with a second larger cam 34 which on depression of a button beyond the latched position moves the member 14 through greater angular displacement. Depression of a button operates switch contacts (not shown) to establish, for example, a telephone speech circuit, whilst the further depression may operate further switch contacts in, for example, a ringing circuit. The hookswitch of a telephone may be arranged to rotate the member 14 and release any latched pushbutton.

IPC: H04N1/04
Filed: 1964-02-25
Abstract: 1,033,631. Copying by scanning. CROSFIELD ELECTRONICS Ltd. Jan. 26, 1965 [Feb. 25, 1964], No. 7817/64. Heading H4F. An original 1 to be copied and a lightsensitive medium 13 on which the copy is to be reproduced are supported by a drum 2 which is subjected to rotational and axial displacements with respect to analysing and reproducing light sources 4 and 11, the arrangement being characterized by the use for the light sources of cathode-ray tubes which are subjected to deflection in the direction of the drum axis and in the direction perpendicular thereto so as to prevent premature fatiguing to the phosphors. The first deflection is controlled by a sine-wave generator 14 mounted on the drum shaft so as to be synchronous with the rotation, whereby the scanning lines traced on the drum surface, although not straight, remain parallel. The second deflection is controlled by a sawtooth generator 15 which is synchronized with the drum axial displacement so as to make one cycle during a complete scan of the original 1 and medium 13. In a typical arrangement, the scanned areas on the cathode-ray tube phosphors are seven inches square and are reduced to one half-inch square on the drum surface by optical systems 5 and 12. The illustrated arrangement is adapted for colour reproductions by the use of three photomultipliers 8 with associated colour filters 7. The signals are applied to a computer 9 from which an output signal is derived to modulate cathode-ray tube 11. In a modification, medium 13 is exposed in contact with original 1 with the use of only one cathode-ray tube which is modulated by the signal from the computer.

Title: An improved device for lifting the wheels of motor cars and other vehicles
IPC: B60S9/06

Abstract: 350,933. Jacking attachments on vehicles. LEDOGARD, R., 17, Rue Thiers, Pontoise, Seine-et-Oise, France. March 11, 1930, No. 7892. Convention date, March 11, 1929. [Class 79 (iii).] A wheel-jacking attachment on a vehicle comprises a lever 15 with a pivoted foot 26, constrained by a pivoted tie rod 17 and actuated at its upper end by means imparting movement in a predetermined path so that the axis of the pivotal connection 25 to the foot 26 rises or falls in a vertical plane. The parts are carried by a frame or casing comprising a pair of side-plates 1 connected by spacing and other bolts 2, 3, &c., and having lugs 4, 5 attached to pins 6, 7 passing through eyelets 9, 10 on a plate 8 clamped between the wheel axle 11 and its associated suspension spring 12. A vertical straight-line motion of the lower end 25 of the lever 15 is obtained by the constraint of rollers 22 at the upper end in suitably designed guide slots 23 in the side plates 1. The main jacking-lever 15 is of channel formation with side extensions at the ends for the pivotal connections. The upper end of the tie-rod 17 is forked and pivoted to the side-plates 1 by pins 19 giving central clearance for the actuating means. As shown, the upper end of the lever 15 carries a pivoted nut 28 threaded on a screwed rod 29 journalled at one end in a pivoted bearing 30 and provided with an extension 32 for rotation by a spanner &c. The free end of the threaded rod is protected by a lubricant-containing casing 33 retained upon a sleeve extension of the nut 28 by a bayonet point 35 in conjunction with a spring 36. The load on the thread in the initial movements may be relieved by a spring between the nut 28 and the bearing 30 ; alternatively the trunnions of the bearing 30 may be mounted in slots in the side-plates and connected by a link to a point on the lever 15 below the pivotal connection 16. Plates 24 cover the slots 23 upon the outside whilst, when the device is raised and out of action, the side cheeks of the lever 15 close the slots 23 on the inside to exclude dirt &c. Other actuating means may be employed. For instance, the screw 29 may be replaced by a piston operating in a pump cylinder replacing the sleeve or casing 33. The foot 26 may be perforated as at 27 to enable a sole plate or packing piece to be attached.
