Title: Means for the synchronisation of broadcast wireless sounds and kinematograph films
IPC: G03B31/00
Filed: 1928-07-23
Abstract: 320,881. Verity, C. H. July 23, 1928. Divided on 318,847. Synchronizing picture-projection with sound transmitted by line or wireless. - Broadcast sounds are synchronized with kinematograph films illustrating the subject broadcast, and projected in one or more cinemas by the aid of duplicated strips on which the speech, music, &c., is marked, a copy of the strip being supplied to each cinema to be driven by the projector therein, so that the operator by means of his copy strip and the speed-regulator can adjust the picture projection to synchronize with the received sounds. The lines of the markings on the strips are numbered, and the picture film is numbered to correspond therewith so that, in case of breakage, synchronism can again be attained. When so arranged, an operator at the broadcasting station can indicate, by subdued tones or on another wave length to the operator at the cinema the number of the line of the strip in the broadcasting studio corresponding with the sound being broadcast by an individual or a sound-reproducing apparatus. Apparatus for preparing the original control strip comprises a movable frame 9, Fig. 1, supporting a camera or projector 1 driven from a motor 2 which drives intermittently, through a pin 23 on the wheel 13 and a toothed wheel 3, a sprocket drum 4 over which a paper strip is led from one roll to another, the strip being drawn past an opening 6. The sounds made by the broadcaster whilst making the picture film are marked, for example in shorthand, through the opening 6 on the strip during its intervals of rest, which may be indicated by a signal, and the lines of these markings are numbered to correspond with numbers marked on the picture film. The shorthand markings and. numbers are then transcribed by a typewriter, and a number of copies made on different strips or by photographic copying on several strips. One of these strips is supplied to each cinema and driven in conjunction with the projector so as to throw an image of the words or marks on the strip on to an auxiliary screen which can be seen by the operator who also receives by wireless and headphones an indication from the broadcasting studio of the sound being broadcast. The operator is thus enabled to adjust the drive of the projector so that the words &c. shown on his auxiliary screen coincide with those broadcast from the studio.

Title: Improvements in cap assembling apparatus
IPC: B21D51/46
Filed: 1944-04-17
Abstract: 584,855. Cap assembling apparatus. CROWN CORK & SEAL CO., Inc. April 17, 1944, No. 7110. Convention date, March 23, 1943. [Class 125 (iii)] An apparatus for providing a container closure cap shell with a cushion disk, to constitute for example a crown cap which includes a skirted metal shell and a disk of cork or cork composition, and for applying to the disk a facing or "spot" to protect the container contents from contact with the disk, is provided with means whereby the output of shell and disk assemblies from one part of the apparatus can be passed directly to the spotting apparatus or can be used to bye-pass it. Crown shells are contained in a hopper 53, Fig. 2, and cushion disks in a hopper 69. Shells pass to a feed disk 55 and thence to a step-by-step conveyer as in U.S.A. Specification 1,469,557 in which the shells rest on tracks and are moved by orbitally-moving racks. Adhesive is applied by spreaders 66, 67 and cushion disks fed from hopper 69 through a vibrated tube 70 are thrust into the shells by a plunger operated by an eccentric 74. The assemblies pass to a dial 83, Fig. 9, rotated synchronously with a vertical dial 88 to which it passes the assemblies; these are heated and held in recesses by spring plungers which keep the disks under pressure, the period of rotation of dial 88 allowing time for the adhesive to dry. From dial 88 the assemblies pass down a chute on to a disk 108 from which they are swept by mechanism 139 to a delivery conveyer 130. When, however, it is desired to apply a spot, a wall on the periphery of disk .108 is replaced by a tunnel 149 through which the assemblies pass to a disk 143 and thence to a rack conveyer 147, Fig. 9. While on this conveyer a punch on a vertical slide 157 punches a spot from a strip of adhesive spot material and deposits it on a disc which is previously heated. The assembly is then received in a pocket in a pressure dial 160 and is pressed by a reciprocable plunger 163. The assembly is then delivered by a belt to disk 108 and swept on to delivery belt 130. A device for removing assemblies through an opening in the tunnel in case of jamming by directing an air blast on them is described. A magnet may be positioned under disk 108 to prevent the shells from fluttering. The machine may be used to continuously assemble shells, disks and spots; to assemble shells and disks only; or to apply spots to shell and disk assemblies supplied independently. The machine may be in two twin parts delivering to a common delivery belt.

Title: Method and apparatus for electron beam welding
IPC: B23K15/00
Filed: 1967-02-10
Abstract: 1,114,727. Electron beam apparatus. D. SCIAKY. 15 Feb., 1967 [6 May, 1966], No. 7275/67. Heading HID. [Also in Division B3] In electron beam spot welding overlapping workpieces 38, 40 the weld zone is enlcosed by evacuated opposed tubular dies 12, 22 pressed together to seal the workpiece interface and an electron beam is directed through the passage 24 formed by one of the dies 22. The beam may be orbited within the die 22 to produce a circular, or oblong or spiral weld or a weld in the form of two concentric circles. The workpieces may be alloys of aluminium or titanium or stainless steel. To assist in the sealing of the interface the workpiece surfaces may be coated with a sealing compound, a layer of a metal, e.g., aluminium, may be interposed between the workpieces or a ring of a metal such as indium may be interposed to produce a seal when the dies 12, 22 are pressed together. Alternatively a seal may be effected by passing a current between the dies 12, 22 to soften the metal at the interface. The lower die 12 is fixedly mounted on the machine frame 10. The upper die 22 and the welding head 18 are carried by an arm 30 connected by a pivot 17 to the frame 10. A power cylinder 41 acts through a toggle linkage 43 to produce limited movement of the arm 16 and to apply pressure to the die 24. Substantial movement of the arm 16 is produced by a power cylinder 45 connected to the centre pivot of the toggle linkage. A conduit 30 connects the welding head 18 to a high vacuum pump 31. A ball valve 51 is movable to close an aperture 47 through which the beam leaves the head 18 to prevent loss of vacuum. The dies are evacuated under the control of valves 15, 26 by a pump 34. Electromagnetic devices 52, 53 serve respectively to focus and orbit the beam. During a weld the beam current may be gradually increased to welding current and gradually reduced as the weld is ended. The dies may have spherical surfaces co-acting with corresponding seatings so that the dies can adapt themselves to the workpiece surfaces.

Title: Recovery of rhodium from fission products
IPC: C22B11/00
Filed: 1960-03-02
Abstract: Rhodium is recovered from mineral acid solution of fission products by first separating ruthenium tetroxide from the solution and reducing it to a lower ruthenium valence, and thereafter storing the reduced product until the radio-active portion of the ruthenium has decayed to rhodium 103 which is then separated, and reduced to metal. The ruthenium tetroxide is preferably removed by distillation or alternatively by solvent extraction.  According to an example, an acid solution of fission product waste was evaporated to incipient dryness, hydrochloric acid added and the process repeated to destroy nitrates.  Insoluble sulphides, including rhodium were precipitated with hydrogen sulphide and taken up, after washing, in hydrochloric and nitric acids followed by evaporation and addition of sulphuric acid to remove nitrate and chloride. The resulting solution was distilled in the presence of added sodium bromate solution and the ruthenium tetroxide evolved was collected in hydrochloric acid saturated with sulphur dioxide.  Rhodium 102 remained in the residue. The distilled ruthenium tetroxide solution was treated with sodium carbonate to produce ruthenium hydroxide.  This was reduced with hydrogen at 500 DEG  C. and stored for a year to allow the Ru 103 to delay to Rh 103.  The rhodium so formed was fused with a mixture of sodium peroxide and sodium hydroxide and thereafter dissolved in water, boiled, acidified with sulphuric acid and distilled with bromate to remove ruthenium.  The rhodium residue was boiled with hydrochloric acid to destroy the bromate and the solution reduced with zinc, aluminium or sodium formate, chlorinated to yield rhodium chloride which, after purification, was reduced with hydrogen at 600 DEG  C. to form rhodium metal.  Specification 741,986 is referred to.
