Patent GB-521230-A (GB)
Title: Improvements in and relating to carburation devices for internal combustion engines
IPC: F02M7/133
Filed: 1938-11-14
Abstract: 521,230. Spray carburetters. SOC. ANON. SOLEX. Nov. 14, 1938, Nos. 33052 and 33053. Convention dates, Dec. 6, 1937 and Sept. 17, 1938. [Class 7 (iii)] In a carburetter provided with an enriching and pick-up device operating'as a function of the suction prevailing downstream of -the throttle and comprising a feed chamber open to the atmosphere and communicating with a constant-level fuel chamber, the fuel chamber communicates with the mixing chamber through an orifice controlled by a stop-valve which is activated by the suction in the inlet pipe. Fuel from a float chamber 3 flows through a calibrated orifice 6 to a nozzle 4 provided with aeration passages 7 and through a restricted orifice 12 to a chamber separated by another restricted orifice 22 from a fuel well 10 open to the atmosphere. A passage 13 leading from the chamber beneath the well to the nozzle 6 or a separate nozzle is controlled by a stop valve 14 connected to a pair of spring-pressed diaphragms 15a, 15b exposed on the face remote from the valve to the suction above the throttle valve 2, the stop valve 14 being thus opened when sudden opening of the throttle valve 2 causes a rise in the pressure above it. The diaphragms may be large enough to act as a force pump. The well 10 may communicate with the atmosphere through a simple restricted orifice or the orifice may be disposed in a tube 23 to reduce the quantity of fuel stored in the well, the tube being adjustable in the well either manually by a screw thread or automatically by a heat sensitive device and the adjustment also serving to vary the size of the orifice which is controlled by a fixed needle valve. In a modification, the relative adjustment of the orifice and the fuel content has two positions only, the well being divided by a partition into well 10a, 10b, Fig. 8, both of which may be open to the atmosphere through an orifice 11a when a valve 29 is set as shown or one, 10a, be open to the atmosphere through two orifices 11a, 11b and the other 10b sealed ; the change-over may' be effected through a heat sensitive strip actuating a valve which closes alternatively an orifice open to the atmosphere or an opening between the two wells. In another modification, the height of the orifice 22 may be adjusted. As shown in Fig. 14, a slide 44 is disposed between the diaphragms 15a, 15b and their operating spring 19 and has a lost motion connection with a hand-control 47, the device functioning normally in the position shown but the valve 14 being maintained open or closed when the slide is displaced to the left or right. In another form, a valve 39, Fig. 12, on the throttle spindle cuts off the suction from the diaphragms when the throttle is closed or nearly so, any reduction in pressure being communicated to them through a bye-pass 43 having a selfclosing valve 41.

Title: Magnetic deflection yoke circuitry
IPC: H04N3/16
Filed: 1974-07-26
Abstract: 1472266 Cathode-ray tube circuits INTERNATIONAL BUSINESS MACHINES CORP 26 July 1974 [7 Sept 1973] 33054/74 Heading H4T Cross-talk between the horizontal and vertical deflection coils of a magnetic deflection yoke is eliminated by means of a suppressor circuit connected in the horizontal deflection circuit. The circuit 11 comprises a trifilar wound toroidal transformer 36, (Fig. 5), the winding 39 of which is connected between the horizontal amplifier 46 (of relatively low frequency) and one end of the horizontal deflection coil 2 (having distributed capacitance 47) the other end of which is connected via winding 37 to the grounded end of the vertical deflection coil 3 (having distributed capacitance 32) the other end of which is supplied from the vertical amplifier 30 (of relatively high frequency). In operation, since the windings 37 and 39 are balanced and opposed no resultant common mode current flows in the third winding 41. However during the occurrence of vertical retrace pulses 25 (Fig. 4), the capacitance 50 between the coils 2 and 3 causes ringing in coil 2, producing "blips" such as 23 (Fig. 3), in the horizontal sweep 22 and this ringing also causes a transfer back to coil 3 via the capacitance 50 which produces oscillations such as 27 (Fig. 4), in the vertical sweep 26, such oscillations being normally damped out before the end of the waveform as shown at 28. The cross-talk thus affects both the horizontal and vertical deflections and the currents due to this and which flow in windings 37, 39 produces a resultant current in the third winding 41. Adjustment of resistor 43 to critically damp the yoke resonance then prevents ringing and provides undistorted vertical and horizontal sweep waveforms.

Title: Improvements in and relating to the incorporation of pigments and the like in latex
IPC: C08L7/02
Filed: 1930-12-18
Abstract: Powders, pigments, &c. are rendered suitable for homogeneous incorporation in rubber and like latices by subjecting them to the action of steam under pressure before grinding with the latex. There may be in addition to steam, ammonia gas; the vapours of fatty or aromatic amines, substituted or not, such as methylamine, di-ethylamine, aniline or benzidine; carbon bisulphide vapour; or various atomized oils which cannot vaporize without decomposition, such as palm oil or castor oil.  The latex may be concentrated or dilute, or latex serum may be used.  A suitable method of incorporation of the fillers &c. is to place the powders in linen bags, or to form them into briquettes ready for introducing into the autoclave.  In an example 100 parts of 60 per cent latex is mixed with 45 parts carbon black, 10 parts of zinc oxide, 3 parts magnesia, 2,5 parts sulphur, by compressing the fillers (except the sulphur which is added in colloidal form) into briquettes under 200 kgs. pressure.  The briquettes are introduced into an autoclave, a stream of steam is passed until temperature equilibrium is reached, when the autoclave is closed, and the pressure raised to 3 kilograms per sq. centimetre, by injecting steam plus ammonia.  The pressure is then reduced, the briquettes are powdered and introduced into latex.

Abstract: 506,798. Cathode - ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and MYERS, L. M. Dec. 1, 1937, No. 33250. [Class 39 (i)] An incandescent screen comprises a layer of material, such as lamp black, molybdenum or magnesia, thoria or other refractory oxide, of sufficiently poor heat conductivity to prevent lateral spreading of the heat but of large gas content, and this layer is carried on or mounted in close proximity to a tantalum or other metal heater through which current is passed during the degassing operation. The layer carries tungsten or tantalum powder becoming incandescent during operation. A carrier plate CS of tantalum, roughened in caustic potash and slit alternately from either edge so as to provide a zigzag current path between tabs CS3, is clamped by insulated bolts or rivets between windowed plates MP, of mica, and windowed plates NP, of nickel. It is then blackened, preferably in a controlled benzine flame, and tungsten or tantalum powder is shaken on through a muslin sieve. The screen is then mounted in the tube and baked under vacuum; a current is then passed through the plate CS, sufficient to heat it to 2000 K. for a few hours and, when most of the gas from the lamp black has been removed, the degassing is completed by electron bombardment. The lamp black layer may be 25 mm. or less thick, and the tungsten layer j ust thick enough to cover it. In a modification, a molybdenum sheet carrying tungsten powder is mounted against an insulated tungsten wire heater supported on a molybdenum carrier.
