Title: Cine-cameras
IPC: G03B21/58
Filed: 1974-04-11
Abstract: 1468339 Sound cine cameras K VOCKENHUBER and R HAUSER 11 April 1974 [14 June 1973] 04418/76 Divided out of 1467342 Heading G2E In a cinÚ camera having a sound recording head, the film is guided for transmission between a capstan and a pressure means, which can be moved together or apart, and an operating means can effect such movement. As shown, the handle of the camera 101 has at the front a release 120, and at the back a pivotable bar 171. The film F is threaded between a pinch roller 109 and a capstan 108, shown in Fig. 2A in a spaced-apart position. When the two are in contact the film is trans-  ported between them. Roller 109 is carried by a block 186 which can slide on a rod 185 attached at its lower end to a cam 177, and the block is urged upwards by a spring 187. Release 120 is mounted on a slide 173 ending in a prod 174. In the Fig. 2A position the prod abuts the cam 177, and then the release cannot be pressed. If the handle is grasped in the normal way, bar 171 is pressed, so that cam 177 is pivoted anti-clockwise into the Fig. 2B position. Rod 185 is moved upwards so that roller 109 is almost touching capstan 108, this being the "standby" position. An arm 182 of cam 177 also closes a switch 183, which completes a circuit from the batteries housed in the camera handle to the exposure meter. When release 120 is pressed, the prod 174 pivots cam 177 more clockwise still, so that roller 109 is now brought into positive engagement with capstan 108, and the film F is transported Fig. 2C, (not shown). At the same time a switch 172 is closed which energizes the film drive motor 106. If bar 171 is released while release 120 is still pressed, cam 177 cannot return to the Fig. 1 position, and the electrical circuits remain closed. In Fig. 4 (not shown), a different mechanical linkage with bar 171, which is also differently disposed in the camera, is disclosed. In Figs. (not shown) 5 and 6, movement of the pinch roller is controlled by pressure either on a forehead support or on the view-finder eye-piece.

Patent GB-912725-A (GB)
Title: Improvement in or relating to fuel injection pumps for internal combustion engines
IPC: F02M41/12
Filed: 1961-02-07
Abstract: 912,725. Fuel injection pumps. BOSCH G.m.b.H., ROBERT. Feb. 7, 1961 [Feb. 24, 1960], No. 4546/61. Class 102(1). Infuel injection pump and distributer having a reciprocating and rotating piston 7 with a slide valve-controlled spill part 53, 54 the slide valve 15 is actuated by the pressure of fuel fed to the injection pump from an enginedriven feed pump 57. The displacement of the slide valve occurs in three stages, controlled by return springs 31, 46, 42 of different rates, to provide three ranges of delivery rate of the injection pump corresponding to starting to normal running speed, normal running to maximum full-load speed and maximum fullload to maximum permissible speed, the quantity of fuel delivered within these ranges being controlled by a throttle valve 30 in the injection pump inlet. Fuel enters a pump chamber 19 from throttle 30 via passage 28 and ducts 27 in the piston. At the end of the pressure stroke the fuel passes to the injectors 26 via a valve 18, chamber 20 and radial passages 22. For starting the engine, the return springs 31, 46, 42 act to hold slide valve 15 in its maximum-effective stroke position. When the engine has started the feed pump pressure acts through passages 60, 29, 47 and 48 on slide valve 15 to move it downwardly against spring 31 until a washer 45 abuts an adjustable stop 39. In this position the idling speed is controlled by the throttle valve 30 only. On opening valve 30, the engine speed rises, slide valve 15 moving downwardly against a spring washer 46. In this range the maximum amount of fuel delivered by the pump is adapted to the maximum amount which can be burned by the engine without smoke. If the engine is not under load a further increase of speed causes the feed pump pressure to move slide valve 15 downwardly against a spring 42, thereby limiting the maximum permissible speed of the engine.

Title: Improvements in or relating to knife-edge bearings and methods of manufacture thereof
IPC: F16C32/02
Filed: 1950-02-22
Abstract: 681,020. Knife-edge bearings. GENERAL ELECTRIC CO., Ltd., and FIELDING, E. A. Feb. 8, 1951 [Feb. 22, 1950], No. 4592/50. Class 12 (i). A method of manufacturing knife-edge blocks comprises the steps of holding together two pieces of a hard material so that substantially plane surfaces of the two pieces are contiguous, grinding and polishing a first optically flat surface on the pieces of material whilst they are held together, separating the two pieces, holding them together again so that the surfaces on them which formed parts of the first optically flat surface are contiguous, grinding and polishing a second optically flat surface on the two pieces whilst held together again, which surface intersects the second-mentioned contiguous surfaces, and separating the two pieces of hard material again. The two pieces of material are preferably equal and rectangular, having a square cross-section and may be of ruby, sapphire or agate. They may be held together by a suitable adhesive or by a jig or clamp. A knife-edge bearing may be formed by such a knife-edge block co-operating with an optically flat surface of a second member of the same material.

Title: A process for colouring articles and masses obtained from phenol-aldehyde condensation products
IPC: C08L61/10
Filed: 1927-02-18
Abstract: 292,637. Petroff, G. Feb. 18, 1927. Addition to 292,636. Phenol-aldehyde condensation products. - The process of the parent Specification for colouring articles and masses, obtained from phenol-aldehyde condensation products, with solutions of colouring agents in certain organic solvents is modified in that aqueous solutions of organic colouring matters, with or without organic solvents, are used, the articles &c. being pretreated, or treated at the same time, with aqueous solutions of phenol (or its homologues), of sulphonic acids, or of sulphonated oils, with or without organic solvents. Suitable sulphonic acids are those of high molecular weight, such as octohydroanthracene sulphonic acid and isopropylnaphthalene sulphonic acid. The article may be treated subsequently with a fixing agent such as bichromate, alum, aluminium acetate, copper or iron sulphate, or tannin, and an additional fixing with formaldehyde may be effected also. In one example, a sheet of phenol-aldehyde condensation product is boiled in a dilute aqueous solution of phenol and sulphonated castor oil, and then in a dilute acetic acid solution of malachite green, the colour being fixed by further treatment with dilute bichromate solution. In another example, the treatment comprises heating in an aqueous solution containing malachite green, acetic acid and phenol, followed by fixing with bichromate solution, with or without a further treatment with formaldehyde solution.
Patent GB-879436-A (GB)
Title: Improvements in and relating to clutches adapted for use in gear-change mechanisms
IPC: F16D25/062
Filed: 1959-02-10
Abstract: 879,436. Positive clutches. WOODWARD, M. H. Feb. 2, 1960 [Feb. 10, 1959], No. 4679/59. Class 80 (2). Positive clutch members 15, 28 having engageable teeth 20, 38 may be connected by a ratchet clutch 18, the inner race 16 of which is formed with a friction synchronizing cone 21 engageable by a corresponding cone 26 on a synchronizing ring 25 in splined engagement with the clutch member 28. In the form shown, for a motor car change-speed gear including a driving gearwheel 12 and a driven shaft 11, the clutch member 15 is bolted to the gear-wheel and the clutch member 28 is in splined engagement with the shaft. To engage the clutch teeth 20, 38 when the gear-wheel 12 is rotating more slowly than the shaft 11, corresponding to changing- down the motor car gearing, liquid under pressure is admitted through a duct 36 to a space 31 within the clutch member 28, this space having a fixed reaction wall 33 fast with the shaft and also being formed in part by the synchronizing ring 25 which is splined for axial movement relatively both to the clutch member 28 and to the shaft. As the liquid under pressure is admitted to the space 31, the synchronizing ring 25 is moved leftwards to engage the friction cones 21, 26. Accordingly, the inner race 16 of the ratchet clutch 18, which is freely rotatable on the shaft 11, is accelerated relatively to the gear-wheel 12, so that the following leftward movement of the clutch member 28 allows its splines 29 to slide into engagement with splines 19 on the inner race of the ratchet clutch. Acceleration of the driving means rotating the gear-wheel 12 then allows synchronization of the speed of rotation of the clutch member 15 with the clutch member 28, so that the teeth 20, 38 can slide into mesh. To disengage the teeth 20, 38, the space 31 is vented to exhaust via the duct 36, and liquid under pressure is instead supplied through a shaft duct 37 to a space 32 on the opposite side of the fixed reaction wall 33. If the teeth 20, 38 are to be engaged when the directions of relative rotation therebetween are reversed, corresponding to changing-up in the changespeed gear, the speed of rotation of the gearwheel 12 is first reduced by throttling down the motor car engine, until it is slightly less than that required for synchronization, with the ratchet clutch 18 overrunning as before.

Patent GB-223800-A (GB)
Title: Process for the production of soluble barium salts
IPC: C01F11/00
Filed: 1924-02-27
Abstract: Barium salts such as barium chloride or nitrate are obtained by the reaction of an alkali salt upon a solution of barium sulphide incompletely saturated with sulphuretted hydrogen.  On cooling the reaction mixture impure barium chloride crystallizes out, and on evaporating the mother liquor to half its bulk a complex salt separates containing sodium, barium, chlorine, and sulphur, leaving a mother liquor of pure sodium hydrosulphide.  The impure barium chloride and the complex salt on treatment with saturated solution of barium chloride are converted into crystals of barium chloride.  The wash liquors are added to barium sulphide solution for the next operation.  Alternatively the barium chloride may be added to the barium sulphide solution containing sulphuretted hydrogen before the sodium chloride is added.  Pure barium chloride then crystallizes out on cooling, and on evaporation of the mother liquor to half its bulk the complex salt above-mentioned separates and may be added to the next batch of barium sulphide containing sulphuretted hydrogen.

Abstract: 350,516. Screwing and tapping. CRAWSHAW, L. S., Standard Screw Works, Charles Street, Halifax, Yorkshire. Feb. 15, 1930, No. 5109. [Class 83 (iii).] Yielding-drive attachments.-A screwing die, diehead, tap, &c., is attached to the turret or toolpost, &c., of an automatic lathe by means of a friction clutch which slips continuously during screwing so as to cut at a reduced speed without the use of reduction gearing. The die, tap, &c., is carried in a holder 7 which is attached to a shank 1 by means of a screw-thread 11 of opposite hand to that of the die or by a cam preferably of helical formation. The holder is rotatable on the screw 11 within the limits of adjustable stops 9, 10 and the shank 1 is rotatable within a sleeve 2 secured to the turret &c. The shank and sleeve are connected by a yielding clutch, preferably consisting of plates 3, 4 splined respectively to the sleeve 2 and a second sleeve 5 keyed at 6 to the shank. In operation the die &c. is fed against the rotating work whereupon the holder 7 is screwed partly off the cam 11, thus giving the die a lead on the work and also imposing pressure on the plate clutch. The die then screws the work but rotates with it to some extent whilst the clutch slips, the amount of slip depending on the amount by which the feed of the die is less than the pitch of the thread being cut. On unscrewing the die, the holder returns to its normal position and stops 12, 13 are brought into engagement to effect a positive withdrawal or in the case of opening-dies the return is performed by a spring, cam, &c. The die may be carried by the sleeve 2 and the shank 1 secured to the turret and the die &c. may, be rotated whilst the work remains stationary. The stops 12, 13 may be replaced by a ratchet.
