Title: Machine for closing metal boxes
IPC: B21D51/32
Filed: 1920-06-25
Abstract: 146,185. Soc. E. W. Bliss & Co. March 29, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Seaming.-A roller seaming-machine for non-circular sheet-metal boxes has one pattern cam 4, Figs. 3 and 4, corresponding in form to the boxes, two closing cams 32 for moving rollers 30 to close the seam, and differential gearing, set in operation by the box-holding mechanism, for operating the closing cams. The cam 4 and upper chuck 3 are fixed on a non-rotating spindle 2 carrying a sleeve 14 which is driven by gearing 16 and has rocking arms 25 which engage the cam 4 by their bowls 26, and shafts 34 with gears 35 in mesh with a gear 36 at one end and the cams 32 at the other. The operation of a treadle 48, Fig. 2, first raises a chuck 47 to clamp the box against the chuck 3 and then through linkwork 51, 39 raises the gear 36, which is loose on the sleeve 14 and normally rotates therewith by reason of its bowls 43, Fig. 3, engaging recesses in the sleeve. The gear 36 is thus released from the sleeve 14 and engages a clutch 42 driven at a slightly different speed by gearing 21 so that it makes half a revolution relatively to the sleeve 14 imparting one rotation to the gears 35 and cams 32 which successively operate levers 28 carrying the rollers 30 to close the seam, and then the bowls 43 fall into their recesses again. The return of the gear 36 is assisted by a spring 53 and withdraws the chuck 47, the box being freed by an ejector 9 operated by a spring 11.

Title: Improvements in and relating to television apparatus
Inventor: GERMANY LESLIE WALTER
IPC: H04N5/21
Filed: 1950-07-11
Abstract: 697,966. Television. PYE, Ltd. July 11, 1951 [July 11, 1950], No. 17361/50. Class 40 (iii). A circuit arrangement for eliminating lowfrequency interference on a television waveform comprises a circuit which produces an output corresponding to any low-frequency interference present and means for combining the output subtractively with the original television waveform. Positive-going television video signals are applied to the control grid of valve V1, the output circuit of which comprises a diode V2 and condenser-resistor network C, R. Lowfrequency interference producing a variation in the peak level of the line-synchronizing pulses will result in a corresponding signal being produced across the condenser C, this signal being applied to the control grid of valve V3. The television video signal is also applied to the control grid of valve V4 which has a common anode circuit with V3. The signal appearing in the common anode circuit consequently comprises the interference signal combined in antiphase with the video waveform whereby the interference present originally in the video waveform is substantially eliminated. This signal is satisfactory for use at a transmitter for application to a monitor; however, an improved signal is obtained for transmission by application of the signal to a valve V5 including a delay-line circuit connected to its anode to derive line-synchronizing pulses which are applied to pulse-shaper V6 and phase splitter V7, the latter delivering a pair of oppositely phased pulses which are applied respectively to the oppositely-poled diodes V9A, V9B, providing a diode-clamp circuit. The video waveform is applied to the control grid of valve V8, and lowfrequency interference is eliminated therefrom in the anode circuit of valve V8 by means of the action of the diode clamp.

Title: Improvements in or relating to colour temperature meters
IPC: G01J5/60
Filed: 1949-06-30
Abstract: 666,009. Measuring colour temperature. SANGAMO WESTON, Ltd. June 30, 1949 [Dec. 31, 1948], No. 17369/49. Class 40 (iii). In a system for measuring colour tem. perature for photographic purposes, adjustment of the relative illumination of a blue. sensitive and a redsensitive photo-cell to balance a bridge circuit of which each cell form, an arm, is effected by a shutter carried by an instrument pointer, the pointer then indicating the colour temperature directly. As shown, photo-cells BT and RT, sensitive respectively to blue and red light and each connected to a battery B, are illuminated through an aperture W by the source. Manual adjustment of a pointer P carrying the shutter O reduces the light reaching one cell and increases that to the other until balance is indicated by a galvo G connected across the cell and battery junction. If the illumination intensity is small condenser C may be charged when closing of switch S will indicate out-of-balance on the galvo. A filter F coinpensates for the greater sensitivity of the red cell to balance the circuit at a predetermined colour temperature and eliminates an output peak in the blue part of the spectrum.

Title: Continuous system for fabricating metal products
IPC: B22F3/18
Filed: 1961-05-16
Abstract: In a continuous process of forming sintered rolled strip such as Pb, Al, Cu, Nb, Ta, Mo, Ti, Zr, W, stainless steel and iron, molten metal is converted into solid particles preferably over 1000 microns in size, the particles are continuously conveyed to a heater where they are heated to above their recrystallization temperature but below their fusion point and the heated particles are then hot rolled.  As shown in Fig. 1, molten metal is poured from a ladle 11 into a granulator 10, the particles or fibres are then conveyed to a store unit 15 via conveyer 13, heated in furnace 16 in hydrogen or an inert gas and finally hot rolled at 18 and cold rolled at 20.  The furnace 16 may be vibrated and in the case of Al particles the heating may be carried out in air to form an oxide skin on the particles.  In a further embodiment the hot rolling may be carried out in two stages with an intermediate heating step. Alternatively a single reversing mill may be used for hot rolling.  The granulator may be a rotating crucible of the ceramic disc or perforated disc type.  Fig. 4 shows an arc melting type granulator for W and Mo metal in which electrodes 32 and 32a are rotated by motor 33 so that the molten metal is centrifugally dispersed as it is formed by the arc.  In a further embodiment, Fig. 5 (not <PICT:0972305/C6-C7/1> <PICT:0972305/C6-C7/2> shown), the metal from the arc electrodes is atomized by a stream of hydrogen. Specification 964,002 is referred to.

Title: Improvements in or relating to the production of artificial filaments
IPC: D01D5/04
Filed: 1946-06-13
Abstract: <PICT:0613164/IV(a)/1> Artificial filamentary materials are obtained by extruding a solution of a filament-forming material in a volatile solvent through a spinning jet into a spinning chamber, setting the filaments in a mist of droplets of an extractant liquid which dissolves the volatile solvent, and removing volatile solvent from the spinning chamber through an opening in the vicinity of the spinning jet by suction produced by a jet of aspirating liquid which is a solvent for and absorbs the volatile solvent.  Most of the solvent and extractant liquid are dissolved by the jet and removed, while the air may be returned to the spinning chamber in the vicinity of the spray device through which the mist of droplets is introduced. Spinning speeds of more than 300 metres per minute may be attained. The filament-forming material may be cellulose acetate dissolved in acetone, and the filaments may be extruded into a mist of water droplets.  The acetone vapours may be removed by an aspirating jet formed by a stream of water forced through a nozzle under pressure. The spinning solution, the water to be sprayed into the chamber, and the water forming the aspirating jet, may all be heated.  Instead of acetone, there may be used ethyl ether-alcohol mixtures, di-chlor-methane, or carbon disulphide, as the volatile solvent, and instead of water there may be used methanol or hexane as the liquid for the mist and aspirating jet.  Other cellulose esters or ethers may be used instead of cellulose acetate.  As shown in Fig. 1, artificial filaments are obtained by extrusion of spinning-solution from nozzle 10 in the closed spinning chamber 4.  The filaments 11 leave the chamber through orifice 18.  Spray nozzles 13 form a mist of water or other extractant liquid and the falling spray p  collects in a well 16.  A tapered neck 17 prevents liquid from falling through the orifice.  Solvent-laden air is aspirated from the top of the chamber through pipe 25 by means of a jet 27 which discharges water or other liquid under pressure through a constriction into pipe 29. To enable the pressure in chamber 4 to be adjusted, a pipe 30 with valve 31 connects pipe 29 to the lower end of the chamber.  Liquid from pipe 29 is removed through valve 32.  Specification 581,354 is referred to.

Abstract: 710,359. Circular looms; beat-up motions; riving shuttles. QUALITEX-SOC. DUNOD & CIE. July 27, 1951 [July 27, 1950], No. 17819/51. Class 142(2) Beat-up motion, Fig. 10. The weft 69 is beaten-up by blades 180 housed in slots in a ring 175 and pivoted about a rod 176, each blade having three teeth 180b; wheels 179, following the shuttles round the loom, rock the blades in succession against the action of springs 177. Driving shuttles, Fig. 4. Revolving arms 23 carry coils 75 energized by short pulses produced by discharging a condenser charged to 2,000 volts. Each' shuttle has armatures 77, which are conductive but non- magnetic (e.g. aluminium), and an armature 76, which is magnetic but relatively non-conductive (e.g. laminated iron). The spacing of the coils and armatures is such that attraction forces having radial and tangential components cccur on the armatures 77, and similar repulsion forces occur on the armature 76. When the shuttle is symmetrically disposed with respect to the arm 73 (as shown), the forces balance out; when the loom is running, friction causes the shuttle to lag, whereupon the radial forces still balance, but a resultant tangential force remains to propel the shuttles. Shuttle, Fig. 1. In addition to armatures on its inner side (described above) the shuttle has wheels 108b on its outer side which run against a ring 108c surrounding the reed 108a. A bobbin in a case 68 is located by a spring finger 100 engaging one of a number of grooves 100a. The weft is taken through the bore of the bobbin and laid near the apex of the shed by a tube 71.
