Title: A thermographic method of copying
IPC: G03C5/08
Filed: 1965-03-10
Abstract: 1,101,483. Thermograph processes. FUJI SHASHIN FILM KABUSHIKI KAISHA. March 10, 1965 [March 12, 1964], No. 10269/65. Heading G2C. A thermographic process comprises placing a material consisting of a support coated with a layer containing a material which is associated with water of crystallization which is released on heating or this material may be rubbed into the support in contact with an original, exposing to infrared radiation and developing the latent image produced with a powdered developer. Positive images are produced with a short exposure when the corresponding image areas are wetted whilst negative images are produced with a larger exposure as the water produced is evaporated from the image areas. The material may be dispersed on a binder and be coated on a polyester support or be vacuum deposited on a support. The developed image may be fixed by exposure to trichlorethylene vapour. Specified materials which are associated with water of crystallization are sodium, cobalt and lead acetate, mono-, di- and tri-sodium phosphate, sodium and ferrous sulphate, lanthanum chloride, bismuth nitrate, potassium tartrate, sodium thiosulphate, metaborate and perborate, ferrous and ferric ammonium sulphate, ammonium and potash alum, clay and bentonite.

Abstract: 436,447. Transformers. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. April 5, 1934, No. 10363. Convention date, April 5, 1933. [Class 38 (ii)] The power factor of the circuit supplying current to the transformer 10, Fig. 1 is regulated by connecting condensers 18 between the minimum voltage tapping points 15 of, and the tapping switches 16 associated with, the two secondary windings 12, 13. The load circuit 14 is connected on one side to the junction of the windings 12 13 and on the other side through circuit breakers 17 to the tapping switches 16. Increases in the secondary voltage caused by operation of the switches 16 cause corresponding increases in the leading current introduced into the transmission circuit by condensers 18. In a modification the transformer 10 has one secondary winding, an associated condenser being connected between the minimum tap of this winding and the middle point of a reactor which is connected also at its middle point to one load conductor and at its ends to the tapping switches. Alternatively the primary winding and not the secondary winding is provided with tappings and associated switches and reactor. The condenser being connected between the minimum voltage tap and the reactor. In another arrangement a tapped auto-transformer 10 is employed and a series transformer 19 is arranged with its secondary winding 20 in the load circuit 14 and has its primary winding 21 connected between the middle tap of winding 12 of transformer 10 and the middle point of the reactor 22 which is connected to tapping switches 24 through circuit breakers 23. In the position shown the transformer 19 produces a negative boost in the circuit 14, the condenser 18 being connected as shown to take a leading current which increases as the voltage in circuit 14 increases. In a modification the winding 21 is connected between the tapping switches and one side of the auto-transformer the condenser 18 being connected across a tertiary winding of the series transformer 19 or alternatively being connected across the secondary winding of the series transformer 19.

IPC: B61F17/26
Abstract: 105,861. Abbott, J. Oct. 5, 1916. Force-feed lubricators.-The rotary axles and wheel hubs of railway or tramway vehicles are lubricated by stationary apparatus which lifts the axle and injects oil into the clearance spaces in the axle bearings and wheel hubs. A pair of standards k inside the track support pumps r which are connected to a common reservoir u and are removable vertically through the ram guides. The top of each standard is inclined in such a way as to lift the axle passing over it, and the axle depresses and operates the pump. This lifting reverses the clearance space in the wheel hub b, which is free to rotate on the rotary axle d, and oil is sumultaneously injected from 'the pump nozzle z through the axle bearing j into the wheel hub. The oil in the bearing j is transferred to the axle by jolting during the travel of the vehicle. The hub b has an end wall c to retain the oil and a groove i to store it. The wheel is secured on the axle by segments g held by pins e and rotating in a groove f. The track m may be depressed at the point mearest to the pump to assist in reversing the clearance from the upper to the lower part of the wheel hub.

Abstract: 454,962. Sliding - clasp fastenings. LONGMORE, C. F., 100, Shortheath Road, Erdington, Birmingham, and LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London. April 11, 1935, No. 11289. [Class 44] A slider which can be locked at any position along a sliding-clasp fastener by a locking arm engaging the elements has the locking arm normally held in such engagement by means of a non-metallic elastic body, under some compression, such compression being further increased when the locking arm is disengaged by operation of the pull tab. For instance, a locking arm of L-shape with one limb 12 thereof received in a slot housing 11 at the head of the slider and mounted on a pivot 14 in such housing has such limb 12 urged outwardly by a solid cylindrical plug of rubber 16 whereby the other limb 13 is maintained in locking engagement with the fastener elements 18. Where the locking arm is protected by a covering bridge piece the plug may be located between the underside of the covering bridge piece and the top of the locking arm and may be held in position by adhesive or by fitting in recesses. The compressible member may be of cork, felt, or spongy rubber.

Abstract: 1476832 Spray-producers CONCAST AG 18 March 1975 [20 March 1974] 11304/75 Heading B2F [Also in Division B3] A continuously cast strand 20, whilst being supported and guided, e.g. by upper rolls 21 and paired lower rolls (not shown) is cooled by spray from nozzles 1-4, Fig. 1, or 40-42, Fig. 4, on holders 9-11 or (12), 13, (14), which are rotatable to be indexed simultaneously to positions in each of which at least one of the spray nozzles on each holder is directed perpendicularly towards the strand path for spraying the strand while the other nozzles are not so directed nor supplied with coolant. In Fig. 1 each nozzle 1, 2, 3, or 4 is capable of wetting the entire width of the strand 20 and only one nozzle on each holder 9, 10 or 11 is indexed into spraying position at one time. The axes of the holders 9-11 may extend in the direction 6 of casting instead of transversely thereof as shown. In Fig. 4 the nozzle holders are elongated and each holder (12), 13 or (14) is hexagonal in section, providing six faces each bearing at least two nozzles 40, 41 or 42 which in combination are capable of wetting the entire strand width. Each holder is rotated against a fixed block (28) or 57, Fig. 4, through which coolant is supplied, by way of a spring-loaded annular sealing member (27), Fig. 2 (not shown), to the nozzle duct which is chosen to be in register with the member (27) by indexing of the holder. One holder is indexed, by a drive such as a pneumatic stepping-cylinder 62 and ratchet lever 61, and the remainder move correspondingly since they are interconnected by a chain transmission 16, Fig. 1. Nozzles may give different distribution, discharge rates or angle 46, Fig. 4, of spray fan 7, so that, by indexing the holders, appropriate nozzles can be selected according to different casting cross-section sizes, withdrawal rates or steel quality. A valve in the pipe 58 supplying cooling water to the block 57 controls the flow to the nozzles. For inspecting nozzles which are indexed out of operating positions the block 57 may be capable of supplying water to the nozzles so positioned. Indexing of the nozzle holders is performed by electro-magnetic valves in response to signals from a control desk which has indicators to show which nozzles are operating.
