Title: Improvements in or relating to claw clutches
IPC: F16D11/14
Filed: 1933-07-31
Abstract: 404,567. Claw clutches. MAYBACH MOTORENBAU GES., Friedrichshafen - on - Bodensee, Germany. July 31, 1933, No. 21463. Convention date, July 30, 1932. [Class 80 (ii).] The side faces of the axially-projecting claws of a claw clutch are each formed as two intersecting planes, the inner or root portion u of the face being undercut while the outer or crown portion o lies in an axial plane, as in Fig. 1, or is undercut to a less extent, as in Fig. 2. In each case, the intersecting line S of the two planes is radial, and the depth of engagement is such that the lines S of the two sets of claws are separated axially by a small amount V. The ends of the claws are bevelled so that the claws ratchet over each other until synchronism occurs.
Patent GB-1028397-A (GB)
Title: Process for making manganous carbonate
IPC: C01G45/00
Filed: 1964-05-26
Abstract: Manganous carbonate of high bulk density, e.g. at least 0.9 g./c.c. or 15 g./cu. inch, is prepared by mixing in aqueous solution a carbonate and an excess of a manganous salt, and retaining the precipitated manganous carbonate in the reaction zone until the desired bulk density develops.  The mixture may suitably be heated to a temperature between 55 DEG  C. and its boiling point.  The pH of the mixture is desirably maintained between 5.7 and 6.2 by adjusting the proportion of manganous salt. The aqueous solutions, e.g. MnCl2 and Na2CO3 should be of a concentration at least 5% by weight, preferably almost saturated.  The increase in density of the product is followed by withdrawing samples, the desired density being achieved after e.g. 1 1/2 to 5 hours.  In a continuous process, once the desired density has been reached, slurry is removed from the reaction vessel while the starting materials are continuously supplied through metered pipes. In another embodiment, portions of the slurry are removed and the precipitated manganous carbonate separated and returned to the reaction vessel.  Addition of high bulk density manganous carbonate to the metal reaction mixture reduces the time required.

Abstract: 1339248 Donning and doffing NIPPON KEORI CO Ltd 10 May 1972 [10 May 1971] 21697/72 Heading D1D A bobbin exchange apparatus comprises (i) an array of side-by-side bobbin grippers 41. 42 (as shown alternate grippers carry empty bobbins) (ii) an array of bobbin holders 21 (iii) means for reciprocally moving the bobbin grippers to and from the spindles and to and from the bobbin holders 21. Operation: Initially, the bobbin grippers are positioned below the spindle rail 13 but above the holders 21. The grippers descend to grip empty bobbins and are then raised to the position shown. The grippers then descend and pick up the full bobbins, rise, move sideways to bring the empty bobbins over the spindles and then descend and rise to donn the empty bobbins. In the final step the grippers are lowered to place the full bobbins on the holders 21 and then return to the initial position. The gripper can grip the bobbins by spring loaded studs, or by pneumatically inflatable bags. The grippers can be moved lengthwise of the frame by a pneumatic cylinder or by an electric motor.

Title: Improvements in or relating to spin stabilized smoke shells
IPC: C06D3/00
Filed: 1963-05-30
Abstract: 985,849. Smoke shells. DIRECTOR GENERAL OF FORSVARETS FABRIKSSTYRELSE. May 30, 1963 [June 13, 1962], No. 21712/63. Heading F3A. A smoke shell has an inner container holding a liquid smoke producer 11 and surrounded by a solid smoke producer 9 of plastics and oxidizer. The shell comprises an outer casing 4 fitted with a screwed attachment tube 3 which holds a cylindrical container 8, 10 filled with the smoke-producing liquid 11, such as titanium tetrachloride, except for a small air space 7. By having only part of the shell filled with liquid and disposing this liquid along the axis of the shell, spin stability is not impaired. The volume between the cylinder 8, 10 and the outer casing 4 is filled with the solid smoke producer 9 comprising 65-85% by weight potassium perchlorate, low viscosity polyester plastics and up to 10% kieselguhr. The attachment tube 3 is formed with a fuze seat 1 provided with a detonator for bursting the shell and the cylinder 8, 10, when smoke is produced at first from the plastics propellant which lasts sufficiently until the more slowly produced smoke from the liquid is able to develop the desired effect. Production of water vapour by the burning plastic propellant helps in making the smoke dense.

Abstract: 1314425 Fastener driving piston ETEM ETABS DE TECHNIQUES MODERNES 6 May 1970 [9 May 1969] 21719/70 Heading B4C A fastener driving piston or plunger for an explosively actuated fastener driving tool comprises two relatively movable parts 15, 17. The rear part 15 includes a recessed portion 16 which has a part conical surface, and a longitudinal slot 16a. The recess receives the rear end of the part 17 and includes a shoulder 16c which limits forward movement of the part 17 relative to the part 15. In use, firing of a charge 8 effects forward movement of the piston to drive a fastener 14. The conical surface 10a of the barrel bore stops the part 15 and causes the portion 16 to grip the part 17 thus braking motion of the part 17 relative to the part 15 until the motion of the part 17 is stopped by head portion 17b engaging the shoulder 16c. Relative movement of the parts may alternatively be allowed by a pin-andslot connection (Fig. 6, not shown). If the forward movement of the part 17 relative to rear part 15 is such that fracture occurs at throat 17g, the part 17 will be finally halted by engagement of surfaces 17f and 10b. Fig. 7 shows a modified plunger in which the part 217 has a threaded head 217a which is introduced into the illustrated position by passing through complementarily threaded portion 23.

Abstract: Distillation apparatus comprises an evaporation chamber 1 and a condensation chamber 2 connected by ducts to form a closed circuit around which a gas is circulated by a fan 3 so that it passes in the same direction through each chamber, as shown by the arrows; the evaporation chamber also carries tubes 4 through which a heating fluid is passed and over which distilland is distributed from a sump 8 by way of a pump 6 and distributer 5, while the condensation chamber carries tubes 12 through which a cooling fluid is <PICT:0894936/III/1> passed and over which distillate is distributed from a sump 13 by way of a pump 14 and distributer 16.  The apparatus may be applied to the distillation of sea-water, and in that case the fan 3 is caused to circulate air through the apparatus, sea-water is supplied to the sump 8, suitably at such a rate that the density of the liquid in the sump is about twice that of sea-water, low-pressure steam or water which has been used for cooling engines, e.g. a ship's engines, is passed through the tubes 4, sea-water is passed through the tubes 12, and distilled water is withdrawn from the sump 13.  The apparatus may be applied also to the distillation of spent lubricating oils, but in this case the gas circulated by the fan 3 should be an inert gas, to avoid explosion.  According to the Provisional Specification the conduits connecting the chambers 1 and 2 may contain plates, to remove entrained liquid from the circulating gas.

Provision may be made to vary. the intensity or the colour of the light emitted through the perforations, say by the employment of colour screens or coloured bulbs. If desired, a panel 20<c> of Crooks' glass may be interposed between the light spots and the eyes. Provision may be made to vary the size of the spots of light. The illuminated screen described may be replaced by other forms of screen ; or screens upon which pictures or moving objects are projected by a cinematograph projector may be employed. Instead of a single telescopic part 7, two or more such parts may be used. A graduated scale or scales to indicate the distance between the ends of the apparatus is preferably provided.
