Abstract: 1,176,688. Brazing. BORG-WARNER CORP. 9 Feb., 1967 [14 March, 1966], No. 6308/67. Heading B3R. [Also in Division C7] In bonding two aluminium and/or aluminium alloy parts an aluminium-silicon brazing alloy and a bond-promoting metal selected from nickel, cobalt, iron, arsenic and silver are provided between the parts, the parts are arranged in a protective atmosphere, the temperature of the parts is increased so that a fused bonding material having as its constituents the brazing alloy and bond-promoting metal bonds together the parts, the temperature of the parts is reduced to about 100‹ F. below the melting point of the bonding material, and the parts are removed from the protective atmosphere at this temperature. An aluminium alloy (at least 99%) heat exchanger comprising fins, tubes and headers is bonded by using aluminium-10% silicon alloy shim stock coated with nickel. Shims are placed around tubes fitted in holes in the headers and at other surfaces to be joined and the assembly is heated in a nitrogen furnace to 1000‹ F. within ten minutes and to 1100‹ F. in 1¢ minutes. The assembly is held at 1100‹ F. for ¢ minute, the heater being then turned off and the assembly cooled to 1000‹ F. within two minutes and removed. In another example a heat exchanger comprises aluminium alloy (1À2% mg.) tubes clad externally with aluminium-10% silicon alloy, the same aluminium alloy headers clad on both sides with the aluminium-silicon alloy and pins of aluminium alloy (at least 99%) without cladding. The tubes and headers are electroless plated with nickel and the parts are assembled and heated in nitrogen to the same temperatures as before. The bond-promoting metal maybe included in the bonding alloy and the protective atmosphere may be of argon, helium, hydrogen or vacuum. The bond-promoting metal may be applied as a coating deposited by vacuum or thermal deposition.

Abstract: 1,005,481. Coiling; rolling. P.U.POULSEN. Feb. 18, 1964 [Feb. 19, 1963], No. 19, 1963], No. 6688/64. Headings B3E and B3M. [Also in Division H1] A method of winding a ribbon electrical conductor on edge comprises rolling the conductor between tapering rollers which are spaced one from the other so that the major diameter of the rollers exerts pressure thereon to deform the conductor into a trapezoidal cross-sectional shape, thereby increasing the length of the outer edge thereof to an extent corresponding to the amount of decrease of the thickness of the outer edge, thereby to enable the conductor to be wound on edge without any stress thereon. The conductor ribbon e.g. 15 mm. x 0À25 mm. is drawn by a driven mandrel mounted on an axle 1, which may be driven by a torque motor, and wound thereon. The ribbon passes between a pair of motor-driven, adjustable, tapered rollers 2, 3 which deform it into a trapezoidal crosssection, Fig. 5. The ribbon is preferably initially produced by rolling flat, circular section material. Coils of a non-circular section may be formed, the rollers being brought together, e.g. by cam means to deform the conductor as it passes around a radiused portion of the mandrel. The roller head moves in a plane perpendicular to the width of the ribbon. When the ribbon has a width considerably greater than its thickness more than one set of rollers may be used.

Title: Film transport apparatus
IPC: H04N3/36
Filed: 1971-03-15
Abstract: 1379905 EVR recording system RANK ORGANISATION Ltd 8 March 1972 [15 March 1971] 6867/71 Heading H4F  In a storage and retrieval system of the type described in Specification 1,379,904, e.g. an EVR system, apparent changes in the picture height due to variations in drive speed of the film are reduced by deriving control signals from signals representative of the phase relationship between field pulses reproduced from the film on line 22 and a periodic reference signal on line 10, e.g. a 50 Hz mains signal. This phase relationship is detected in phase detector 30 which gives a short duration output during the field blanking period which represents in polarity and magnitude the extent of any phase error representative of film speed error. This short duration output is stored, e.g. in a box-car lengthener 32, and the resulting signal in addition to being applied as additional field deflection to the flying spot scanner tube of the film reader as in the above referred to Specification to vary the scanning raster position from frame to frame, is also differentiated, 34, 36, and fed via a temporary store 41 similar to store 32 to control a constant current source 38 whose output is connected together with the output of the field rate circuit 40 (controlled by the reference mains signal) to the scan circuit 16 which effects the field scanning of the flying spot scanner. The effect is to vary the field sync. pulse generation and thereby correct the picture height. Field sync pulses for the EVR output are derived, 18, from the reference mains signal, and conventional film transport drive synchronization is effected by phase comparison, 20, of the retrieved field pulses and the reference signal.

Abstract: 352,007. Copying telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Ranger, R. H. ; .574, Parker Street, Newark, New Jersey, and Smith, S. B. ; 355, Lenox Road, Brooklyn, New York, both in U.S.A.) March 3, 1930, No. 6988. Convention date, March 1, 1929. [Class 40 (iii).] In copying telegraphy, a system for transmitting coloured pictures comprises transmitting signals in accordance with the intensities of elemental areas of the picture, illuminated sequentially with light of different colours, the signals at the receiver controlling recording devices to produce record markings corresponding to the individual colour intensities in the picture transmitted. Transmitter. The picture 3, Fig. 1, is mounted on a cylinder 1 rotated and fed forward on a shaft 5. Light from annular sources 7 is reflected from the picture surface through tubes 9, suitable lens systems 11 and falls on the light sensitive cells 15. Diaphragms 13 adjust the width of line transmitted. The cells 15 are brought into action successively by rotating shutters ABC, Fig. 3, provided with filters of the primary colours, so that each cell 15 is exposed in turn to light that is wholly blue, red or yellow. These shutters are rotated at one-third the speed of the cylinder by suitable gearing 29 from the shaft 5. In a modification, only one cell 15 is used and a shutter composed of equal portions of red, yellow and blue transparencies is rotated before it and again two complementary colours and two cells may be used. When three cells are used, the successive scanning paths are spaced apart as illustrated in Fig. 5 in which the numerals denote the order of scanning the lines and the letters the colour with which they are scanned. Receiver. The drum 45, Fig. 2, is rotated synchronously with the drum 1 and the signals are fed to three recorders A<1>, B<1>, C<1> through a commutator 63. This commutator is rotated at one-third the speed of the shaft 43 through reducing gear from this shaft and puts each of the recorders A<1>, B<1>, C<1> in turn into the circuit of the incoming signals, so that each recorder records its own colour, as transmitted. The recorders, Fig. 4, consist of two plates 87, 89 which are charged by the signals and through which is driven a jet of suitably coloured ink (red, yellow or blue). A valve 101 allows the ink to flow on charging the plates 87 and the stream is deflected according to the charge on the plates 87, any ink falling into the trough 99 being returned to the reservoir. The Specification as open to inspection under Sect. 91 (3) (a) describes as known a method of colour copying telegraphy in which the picture is transmitted several times while using a different colour screen at the transmitter for each transmission, the records at the receiver being superimposed. This subject-matter does not appear in the Specification as accepted.
