Title: Improvements in or relating to combustion apparatus
IPC: F23C3/00
Filed: 1954-07-02
Abstract: 776,932. Cyclone furnaces; generating combustion, products under pressure. BABCOCK & WILCOX, Ltd. July 2, 1954 [July 2, 1953], No. 19459/54. Addition to 763,014. Class 51 (1). Combustion apparatus for fluent fuel comprises primary combustion chambers 1, 2, Fig. 2, each supplied with a stream of fuel, e.g. pulverized fuel entrained in a stream of air, and a stream of combustion air and means, upstream of the point at which the air and fuel streams mix, to effect pulsations in the streams, whereby resonance may be produced in the chambers which. discharge into a cyclone combustion chamber 4 associated with the combustion chamber of a water-tube boiler of the kind described in Specification 598,142. The pulsations produced in the chambers 1 and 2 are 180 degrees out of phase with each other so that the gases entering the cyclone chamber 4 are substantially free from vibration. In operation, combustion air under pressure passes from a duct 17 into an annular duct 16 having a nozzle ring 18 into which opens a ring 19 communicating with a distributer ring 20 to which air-borne fuel is fed through a duct 21. The frequency at which resonance occurs in the chamber 1 is controlled by adjustment of a piston 23 in an extension of the chamber. The combustion chambers are cooled by water tubes 25 embedded in refractory material. In a modification, the primary combustion chambers 1, 2, Fig. 3, discharge tangentially and independently into a vertical cyclone chamber 34 from which the combustion products pass to a radiation chamber 36, while molten slag discharges through an aperture 37. In this modification, the gases entering the chamber 34 from the chambers 1, 2 whirl in the same direction, but in another arrangement, the directions of whirl are opposite. The means for supplying the pulsating streams of fuel to the primary combustion chambers comprise a hopper 50, Fig. 7, containing pulverized fuel which is fed by a screw 51 to a mixing valve 52 supplied with entraining air by a fan 53 connected to a heater 55 heated by the waste gases from the watertube boiler with which the apparatus is associated, and from which air passes to the mixing valve. From the valve, the fuel stream flows through a duct 57 and branch ducts to the distributer rings 20 of the chambers 1, 2. The out-of-phase pulsations are impressed on the fuel streams by dampers 60, 61 in the branch ducts rotated through a coupling from a synchronous A.C. motor. The combustion air streams are supplied to the annular ducts 16 of the chambers 1, 2 by a fan 65 which supplies air to a heater 67 from which the air flows through branch ducts having rotary pulsationproducing dampers 70, 71. Specification 598,142 is referred to.

Title: Improvements in or relating to electric resistance welding machines
Inventor: GORDON SAMUAL HUNTER
IPC: B23K11/00
Filed: 1957-06-21
Abstract: 832,271. Welding by pressure. RESISTANCE WELDERS Ltd. June 11, 1958 [June 21, 1957], No. 19678/57. Class 83 (4). In an electric resistance welding machine for welding lengths of rail, the clamping means 32, 33 for gripping the rail lengths include lower clamping members and upper clamping members movable vertically relatively to the lower members, the machine frame being movable bodily such that the lower clamping members move upwardly and downwardly without movement relative to the frame. In an embodiment a frame 10, Figs. 1, 3, is supported by pairs of rollers 11, 12 at its ends on rails 13 and is movable along the rails by a piston and cylinder device 16, 14. The rollers 12 are mounted eccentrically on a shaft 21 so that rocking of the frame about the rollers 11 is caused by rotation of the shaft effected by a piston and cylinder device 23, 24 coupled to an arm 22 fixed to the shaft. An electric motor-driven pump 28 draws liquid from a tank 31 and supplies it to the cylinders 14, 24. Clamp unit 32 is fixed to the frame and clamp unit 33 is carried on a movable head on the frame, the jaws of the units being movable by fluid pressure. With the shaft 21 rotated to lower the frame, Fig. 1, and the jaws open, the rail 37 last welded is moved to the left and a new rail 38 is fed from the right to meet the length 37. The frame is then moved to bring the meeting ends between the clamp, the shaft is rotated to raise the frame, the jaws are closed, Fig. 3, and welding is effected. The arm 22 may be connected to the piston-rod of a substantially vertical compressed air cylinder, the arrangement being such that as the piston is raised to cause lowering of the frame it engages a stem in the cylinder which moves to compress a spring to assist in taking the weight of the frame. The frame alternatively has at one end a shaft 51, Fig. 6, rotatable in blocks 52 on the floor and is supported at the other end by leaf springs 53. A toggle link 54 is connected to a block 55 on the floor and another link 56 is connected to the frame, the common point 58 of the links being connected to a piston-rod 59 of a liquid or air pressure cylinder 61 on the frame. Movement of the piston effects rocking of the frame.

Title: Improvements in yarn feeding devices for knitting machines
IPC: D04B15/48
Filed: 1948-07-23
Abstract: 655,858. Knitting-machines. HEMPHILL CO. July 23, 1948, No. 19745. Convention date, Nov. 28, 1947. [Class 74 (ii)] Yarn from a supply, wound round a cylindrical cage 1 which is rotatably driven to feed the yarn to the needles of a knitting-machine, is engaged by a take-up arm or take-up arms 54, 55 which in the event of the yarn becoming slack, due to the withdrawal from the supply of more yarn than is required by the needles, decreases or decrease the length of yarn in engagement with the cage to reduce the frictional contact between the cage and yarn and thereby lessen the amount of yarn withdrawn. The cage is driven by a belt 13 engaging a pulley 8 on the cage and a pulley 14 on a driving-shaft 15 rendered operative and inoperative through clutch mechanism adapted to be operated by a cam drum, The take-up arms 54, 55 may be gravity-operated or spring- influenced and are positioned adjacent the cage so that the yarn extends round the cage and outside the arms. The movement of the arms is substantially tangential to the cage so that, they tend to swing towards each other when the yarn is taken by the needles. A cage for each yarn may be individually operated or two cages may be driven from the same shaft 15. Specification 596,351 is referred to.

Title: Digital circuit module test system
IPC: G06F11/273
Filed: 1975-05-12
Abstract: 1498125 Testing digital circuit modules XEROX CORP 12 May 1975 [1 July 1974] 19870/75 Heading G1U A computer controlled test system, particularly for testing a logic integrated circuit of the type that includes triggers which, under the control of a signal on a special pin, can be switched together to form a shift-register into which, and from which, data can be shifted without either affecting, or being affected by, the other combinational logic elements in the i.c., is characterised in that it includes a test circuit able to transfer data between the i.c. under test and a data register within the test system selectively either in parallel or in serial form. The Specification describes, in outline, a system for testing a large i.c. of the type defined above. In principle the test method is as follows. With the appropriate program in the computer, and the appropriate connections made to the i.c. first all the triggers in the i.c. are caused to switch themselves into a shift register. This register is then tested by stepping a pattern through it. Next, having checked that the triggers all function properly, part of a test pattern is shifted into them, then they are caused to resume their normal connections with the remainder of the i.c., and the remainder of the test pattern is applied, in parallel, to the appropriate pins of the i.c. Thus, in effect, the triggers of the i.c. have become an accessory for the test system, in that they store part of the test pattern that is applied to the combinational gating elements of the i.c. Finally, the output from the i.c. resulting from the test pattern is transferred to the computer, the triggers are caused to reform a shift register and their contents are shifted into the computer, and after analysis of the results by the computer the process is repeated for the next test pattern.

Title: Cinematorgraphic film projectors
IPC: H04N3/40
Filed: 1972-04-28
Abstract: 1411441 Television DECCA Ltd 4 April 1973 [28 April 1972] 19932/72 Heading H4F In an arrangement in which a television camera scans intermittently moving cinematographic film to generate corresponding television signals a source of field synchronizing pulses controls the camera scan and means are provided for selecting different cyclic sets of the pulses to control the film traversing mechanism. The invention is concerned with generating television signals corresponding to standard 24 frame-per-second cinematographic film the signals having either the 625 line, 50 field standard or the 525 line 60 field standard, the former standard being produced by advancing the film at 25 frames-per-second and scanning each frame twice whilst the latter standard is produced by advancing the film at 24 framesper-second and scanning alternate frames twice and intervening frames three times. In the latter case the time for which the film is stationary is different for successive frames and when the arrangement is operated at a slow speed such as 1 or 2 frames per second, one of the cyclic sets of pulses derived from the field synchronizing pulses is employed to control the film advance mechanism in such a manner that an accumulating phase error due to this is avoided. Fig. 2, shows the general arrangement in which a two-way switch 12 connects the output of the field synchronizing pulse source 10, selectively, to a 625/50 pulse selection circuit 14, or to a 525/60 pulse selection circuit 12, the outputs from both circuits being supplied to the film advance control mechanism in the film projector 6. Circuit 14 comprises a divide-bytwo logic unit which enables the frame of the film (now advanced at 25 frames-per-second) to be scanned twice and circuit 13 comprises an arrangement, shown in Fig. 1, which from the input field pulses, produces the output cyclic pulse order shown so that with the film being advanced at 24 frames-per-second, alternate frames are scanned twice (525 lines) and intervening frames three-times (787¢) lines. The film is advanced by operating a Geneva star and pin wheel arrangement by a driving motor which is driven continuously when 24 or 25 frame-per-second operation is required. When slow speed operation, e.g. 1 or 2 framesper-second, is required in respect of the 525 line 60 field standard accumulating phase errors are prevented from occurring by means of a logic circuit (not shown) controlled by a photo-cell and lamp arrangement the cell being "shuttered" periodically by means of a semicircular opaque member mounted on the motor drive shaft (Fig. 3, not shown).
