Title: Process for the production of sound and picture records
IPC: G03B31/00
Filed: 1929-11-15
Abstract: 343,910. Associated kinematograph and sound records. NAAMLOOZE VENNOOTSCHAP KœCHENMEISTER'S INTERNATIONALE MAATSCHAPPIJ VOOR SPREKENDE FILMS, AMSTERDAM-BERLIN, 43, Mauerstrasse, Berlin. Nov. 15, 1929, No. 35007. Convention date, Nov. 16, 1928. [Class 40 (ii).] Relates to the production of associated kinematographic and sound records by a process in which the original records are produced on carriers run at different speeds. In order to adapt the picture record accurately to the sound record, so that if required both may be combined on a single film, the number or sequence of images on the picture film is altered during the printing of a positive from the negative picture film by using an apparatus in which the negative and positive films are moved together by a periodically moved conveyer, and the relative movement of the two films can be altered as required. For example, in the case where the sound record has been made on a film run at a greater speed than the associated picture film, individual pictures may be copied more than once, during the printing process, so that a picture film having the same length as the sound film may be obtained. The invention may be applied to processes in which the sound is recorded otherwise than on a film, for example on a plate or wire. Reference has been directed by the Comptroller to Specification 134,357, [Class 40 (ii), Phonographs &c.].

Title: A process for producing germanium monoxide
IPC: C01G17/02
Filed: 1953-12-22
Abstract: Germanium monoxide is obtained from a non-volatile material containing metallic germanium by heating at 900 to 1100 DEG C. in the presence of a flow of a gas mixture comprising an oxidizing gas and an inert gas at a pressure of 2 to 40 mm. Hg below atmospheric and cooling the resulting gas to deposit the monoxide.  A suitable starting material is germanium chips contaminated with silicon carbide and iron and the gas mixture may be air or a mixture of oxygen and nitrogen having more oxygen than air.  According to a typical example the material was placed in a silica boat in a silica reaction tube from which the air was displaced by a mixture of 8.5 parts by volume of nitrogen and 1.5 parts of oxygen.  The tube and contents were then heated to a 1000 DEG C. in an electric furnace and heating was continued for 2 hours in a flow of the gas mixture whilst the pressure within the tube was regulated to 2 to 3 mm. Hg below atmospheric, by which time the temperature had reached 1100 DEG C. Germanium monoxide deposited on the cooled parts of the tube or in a cooled insert.  The deposited monoxide may be converted to germanium tetrachloride by heating the tube to 400 DEG C. whilst passing chlorine through.  Further examples relate to treatment of the material with air.

Abstract: 356,582. Slicing-machines. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ TOT VERVAARDIGING VAN SNIJMACHINES VOLGENS VAN BERKEL'S PATENT EN VAN ANDERE WERKTUIGEN, and BERKEL, W. A. V., 33, Boezemsingel, Rotterdam, Holland. Nov. 28, 1930, No. 35816. [Class 28 (ii).] A slice-stacker, used with a slicing-machine having a reciprocating table, has a slice-conveyer driven from the machine and associated with separate mechanical means which modify the speed of the conveyer to conform with the varying speed of the reciprocating table during the slicing operation, thereby avoiding the tearing of the slices as they are impaled on the conveyer. As shown in plan in the Figure, the slice-conveyer 6 is mounted on a shaft 7 driven by chain and bevel gearing from the hand-wheel shaft 5. The conveyer 6 is not secured rigidly to the shaft 7 but is connected thereto by a compression spring device, so that when the conveyer 6 is temporarily retarded the spring is compressed and when the conveyer is again released the spring accelerates the conveyer until it reaches its normal position on the shaft 7. The retardation is effected by a flexible wire 22 connected at one end 22a to the reciprocating table and at the other end to a spring 23 connected to the other side of the reciprocating table. The spring 23 maintains the wire in tension, the wire being trained over pulleys 24, 26, 28 .. 33, 35, so that between the pulleys 29, 30 it contacts with a grooved segment 21 attached to the top of the conveyer 6 and rotatable therewith. The wire 22 travels at the same speed as the table and frictionally constrains the sliceconveyer 6 to move at that speed during the slicing operation. The discharge fly 16 is actuated by a compression spring which acts when a roller associated with the fly reaches a sudden drop in a cam fast on the shaft 7. The fall of the fly is braked by a brake shoe connected by a link to the fly and moving on a vertical friction surface Specification 353,445 is referred to.

Abstract: 920,942. Stud and socket fastenings; circlips. DEUTSCHE FASTENER CORPORATION. Oct. 22, 1959 [Nov. 3, 1958], No. 35847/59. Classes 44 and 89 (2). A fastener for detachably securing a first sheet 2 to another sheet 3, comprises a resilient retaining member 17 mounted on the first sheet 2 and adapted to engage and retain a movable member 27 mounted on sheet 3, the retaining member abutting against a shoulder 16 on the movable member, and a release member 30 loosely attached to the movable member and adapted to move the resilient member 17 to a position where it is disengaged from the movable member and to hold it in this position. The movable member 27, having a bead 12 attached to end 9, is mounted in a receptable member 6, which is held to the sheet 3 by a snap ring 7. Depressing pushbutton 13 against the spring 14 causes a collar 28 to lift the release member 30 and thereby spread the leaf spring elements 21, 22. The resilience of these elements holds the member 30 in place, while the head 12 is disengaged from the upper ends 23, 24 of the elements (see Fig. 3). The sheets may then be separated, refastening being effected merely by depressing pushbutton 13 again. In another embodiment the movable member contains a bore into which a tool may be pushed to lift a release member having a pin extending aorosa the bore. An alternative method of fastening a receptacle member to a sheet is to use a C-shaped circlip 37 (Fig. 5) which is mounted above the sheet and has ends which co-operate with tapered slots 39 in the receptacle member to press the sheet against a collar 35 on the base of the member.

Abstract: 894,940. Automatic firearms. VOGLER, H., and KRAUSSER, H. Oct. 24, 1959, No. 36101/59. Class 119. An automatic firearm has in combination on a stock a feeding and firing mechanism with a forwardly disposed barrel, the mechanism comprising a casing 27 in which a spring-motor 2 rotates a rotor 1 fixed on to a shaft 9 and having cam surfaces 14 which engage with cam surfaces 15 on a non-rotating slider member 4; the cam surfaces can cock the slider 4 against a spring 5 to co-operate with firing means 18-19 when a latch 21-22 is operated to release it from the cocked position; releasable locking means 12-13 limit the rotation of the rotor 1 except in the firing position, which is shown in Fig. 1. A knob 10 serves to rotate the shaft 9 toward the spring 2 in its fixed casing 3, or to withdraw the shaft to permit removal from the casing 27 for reloading of a multi-chambered drum 8 carried on the front end of the shaft. In the firing position, as well as striking the striker 18, the front face 17 of the slider 4 disengages the detent 13 from the rotor cam 11 so as to allow the spring 2 to rotate the drum 8. On recoil of the slider the detent re-engages the cam 11 to align a newly advanced chamber with the barrel. Fig. 3 (not shown) illustrates an alternative assembly with a removable barrel aligned with the lowest chamber position of the drum 8. The rotor may propel and operate a cartridge belt or tape instead of a drum.
