Abstract: 1,202,817. Trimming tyres. GOODYEAR TIRE & RUBBER CO. 13 Sept., 1968 [11 Oct., 1967], No. 43584/68. Heading B5A.

Abstract: 1285512 Luminescent screens MATSUSHITA ELECTRONICS CORP 11 Sept 1970 [18 Sept 1969 (2)] 43603/70 Heading H1D In manufacturing a screen for a colour television tube of the type comprising a pattern of phosphors with interspersed opaque areas, the latter are deposited by an electro-photographic process. In one method the opaque areas are deposited before the phosphor areas using a transparent photo-conductive plate which is charged positively and then mounted between a shadow mask and a faceplate. The plate is exposed through the shadow mask simultaneously or sequentially from three point sources of light so that it is discharged in areas which correspond to positions of the phosphor dots, and after removal from the faceplate the sensitive plate is developed in known manner using as a toner a negatively charged black powder of graphite or manganese dioxide with a resin coated thereon. The sensitive plate is again mounted adjacent the faceplate and the resincoated black particles are transferred to the faceplate by applying a positive charge to the sensitive plate. Thereafter the faceplate is heated so that the resin melts and secures the powder; the phosphor dots are deposited by known photo-resist processes and subsequently the resin is vapourized and removed by heating carried out after the formation of the metal backing. In an alternative process the phosphor dots are deposited on the faceplate and a positively charged photoconductive plate is mounted within the faseplate on the shadow mask supports and exposed to light through the faceplate. The sensitive plate is developed by an inversion process, positively charged dark particles being made to stick to the exposed areas, and these particles are then transferred to the faceplate.

Title: Apparatus for measuring the inflammable gas content of air samples
IPC: G01N27/16
Filed: 1963-11-06
Abstract: 1,069,493. Gas analysis. AUERGESELLSCHAFT G. m. b. H. Nov. 6, 1963 [Nov. 7, 1962; Nov. 10, 1962], No.43766/63. Heading G1N. In an apparatus for measuring the combustible content of a gas sample, e. g. methane content of air in mines, the sample is burned in a measuring chamber (Fig. 3) and the resultant increase in resistance of a preheated resistor filament D which ignites the gas is used as a measure of the heat released when methane is burned and the change of resistance of a resistor filament K, which is preheated to a lower temperature than filament D, is used as a measure of thermal conductivity of the gas sample which value is also related to the methane content. Both filaments are located in a common chamber, are immersed in the same gas sample, and are included in adjacent arms of a bridge circuit such that an unbalance indicator 4 therein will give an indication of the percentage methane content. The combination of the two effects (thermal conductivity and heat generated) is utilized since with high percentage methane content (over 9-5%) there may not be sufficient oxygen to sustain combustion of all the methane and the meter would indicate a lower methane content than that actually present. A ballast resistor 5 mounted outside the measuring chamber is included in the bridge to accentuate unbalance due to the thermal conductivity effect on the filament K resistance. If the filaments D and K are identical then the effect of the heat of reaction may be paramount in the indicator reading and a ballast resistor 8 may be provided so that the two effects may be evenly matched. Fixed resistors 6, 7 and potentiometer 3 are not located in the measuring chamber. Instead of using the ballast resistor 5 to accentuate unbalance due to thermal conductivity a third filament Fig. 2 (not shown) may be placed in the measuring chamber and connected in the bridge circuit in place of the resistor 7 of Fig. 3.

Abstract: 1522824 Automatic current control CATERPILLAR TRACTOR CO 24 Oct 1975 [23 Dec 1974] 43834/75 Headings G3N and G3R In an arc welding apparatus a travel motor producing relative motion between a welding head and a juncture between workpieces is speedcontrolled in dependence on the welding current. As shown, a welding head 11 is moved by a motor 17 the speed of which is determined by the setting of a variable resistor 57 and of a series resistor 58 for setting a lower speed limit. The voltage across a resistor 34 in the current supply to the welding held is applied to an operational amplifier 43 the output of which is summated at a junction 46 with a pre-set reference voltage from a source 47. The summation voltage, through an amplifier 54, is applied to a motor 53 which drives the resistor 57 so as to tend to maintain the welding current, and consequently the welding electrode height, constant. The travel of a drive 63 for the resistor 57 is limited by a stop 71 and the motor 53 is of a high-resistance low-torque type which is undamaged when stalled with power applied.

Abstract: 1,245,313. Boring earth and rock; piles. TOT AANNEMING VAN WERKEN N.V. 5 Sept., 1969 [5 Sept., 1968], No. 44134/69. Headings E1F and E1H. A hole forming device comprises a pipe 1 which is vibrated into the earth to a predetermined depth, whereupon fluid is introduced through a conduit 3, inlets 2 and non- return valves 13 to remove the earth core from the pipe as a solid mass. The fluid pressure may be gradually reduced so that the core moves at a constant rate. The column is cut into sections and removed by truck. or conveyer. A suspension of bentonite may be supplied through the conduits to lubricate the pipe as it is vibrated into the earth, the pressure of the suspension being increased to remove the core. When boring permeable earth a sealing layer is formed in the lower end of the pipe above the inlets. This layer may be formed by injecting a chemical hardening medium, an emulsion or sheet like sealing elements such as polyvinylchloride sheets in a carrier liquid. In a modification, a cutting member is operable from the top of the pipe to sever the core at the level of the inlets. The pipe may have a round or rectangular cross section. To form a waterproof retaining wall a round pipe 22 is vibrated into the ground and the core removed. A second pipe 23 having rectangular section is introduced adjacent the pipe 22, Fig. 4, and the core removed. A reinforcement is arranged in the pipe 22 and concrete is poured in. The pipe 22 is removed and vibrated into the ground at the far end of the pipe 23. The pipe 23 is filled with concrete in a similar manner and removed to allow merging with the concrete in the cylindrical hole to form a waterproof joint. This procedure is repeated to give a zig-zag wall, Fig. 7 (not shown).
