Title: Improvements in methods for the production of joints between two tubular members on a projection welding machine
IPC: B23K11/14
Filed: 1961-08-10
Abstract: 1,013,731. Welding by pressure. F. PEDLEY. July 24, 1962 [Aug. 10, 1961], No. 28909/61. Heading B3R.  In projection welding together two tubes, the end of a first tube is machined to form a saddle to fit the other tube, the tubes are arranged at right angles with pointed projections on one tube engaging the other tube in point contact or with rods or wires between the tubes and current is supplied to melt the projections or the rods or wires to form spot welds. In joining tubes b, b<SP>1</SP> for furniture, the tube b<SP>1</SP> is supported in a jaw a<SP>1</SP> of a welding machine and the tube b machined to form a saddle provided with pyramidal projections b<SP>2</SP> is mounted in an upper jaw a. The tube b is lowered by a cylinder a<SP>5</SP> into contact with tube b<SP>1</SP> for, say, 5 cycles of a 50-cycle supply and current is supplied to melt the projection and a final pressure lasting, say, 20 cycles is applied. A hole may be formed in the tube b<SP>1</SP>, the saddle being welded around the sides thereof. In a modification, rods or wires c, Fig. 6, on a tape c<SP>1</SP> may be inserted between the surfaces to be welded to form the initial contact.

Title: Gas-material separator
IPC: B01D46/04
Filed: 1962-07-27
Abstract: 962,934. Filters. FULLER CO. July 27, 1962 [Sept. 1, 1961], No. 28972/62. Heading BIT. A separator for separating gas and material carried in suspension in the gas, comprises a casing 2 having an inlet 5 and outlets 6 for the gas, the outlets being surrounded by filters 22 which include filter members 25 of resilient porous sheet material, e.g. a synthetic plastic material such as flexible urethane foam, and the outlets are respectively connected to an exhauster 10 by means of ducts 7 and 8 having lateral extensions 14 and 15 open to atmosphere, the ducts and the extensions being provided with valves so that the outlets may be connected to the exhauster for filtering of the gas or to the atmosphere for cleaning the filters by gas flow in the reverse direction. The lower end of the casing 2 may be in the form of a hopper with a dust-discharge valve. The inlet 5 is tangential to the wall of the casing and may be separated from the outlets 6 by deflectors. The filter members 25 are provided with wire cage supports 23. In operation, the reverse flow of gas when the filter is being cleaned balloons out the filter members 25 which tend to flutter to and from the position B shown chain-dotted in Fig. 1, and this tendency may be enhanced by pulsating the reverse air flow, for example by means of a timing valve. In a modification (not shown) the gas is fed to the separator inlet under pressure, the exhauster 10 being dispensed with and extensions 14 and 15 being open to gas under a pressure which is higher than that of the gas being filtered. Specification 951,020 is referred to.

Abstract: 802,250. Making bags. ROSE BROS. (GAINSBOROUGH), Ltd. Oct. 15, 1956 [Oct. 13, 1955], No. 29128/55. Class 94(2). A machine for producing flat bags by folding a web to tubular form about a flat former and folding over onto the tube, the end portion thereof to close the bag bottom, comprises a thin blade 19 along the former 12, a folder 32 movable transversely across the end of the former, and a folder 37 movable along the former 12. The web 11 is pulled past known tubing means by reciprocating grippers 16 to leave a portion projecting beyond the end of the former. This end portion is folded across the ends of the former and the blade 19 and through an aperture 42 in the folder 37 by the folder 32. The folder 37 then moves to lay the portion along the blade 19. The blade 19 retracts and a T-shaped sealer 43 heat seals the longitudinal seam and also seals the end portion to the adjacent tube wall. The sealer 43 is cut away at 44 to accommodate the retracted members 19, 37, the longitudinal seam beneath this cut away part having been previously sealed by a portion of the sealer extending beyond the actual bag length, during sealing of the preceding bag. The closed bag end is engaged by the grippers 16, the former 12 having end notches to permit this, and the bag is severed from the web by cutters 18.

Abstract: 641,271. Indicators for switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 31, 1947, No. 29133. Convention date, Nov. 2, 1946. [Class 38(v)] [Also in Group XI] An electric range has a heating circuit with multi-position switch controlling different degrees of heat and having a manually-operated knob 13 behind which is a stationary dial 16 divided into sectors a of different colours indicating different heat output positions; and a disc 18 moving with the knob masks the dial 16 except through a peripheral recess 19 in the disc, so that a different colour is exposed for each position of the switch. Word indicia on the disc 18 corresponding to the colours are brought opposite a single position, e.g. the top of the switch, as the switch is moved. The knob 13, is elongated diametrically of the disc, which is mounted on a switch-operating shaft 14 projecting through a wall 12. In a modification, the word indicia are placed on the colour sectors. Several such switches are mounted on the vertical rear splash board of a range. Specification 457,062 is referred to.

Filed: 1945-11-02
Abstract: 602,642. Valve relay circuits. SCOLES, G. J., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Nov. 2, 1945, No. 29205. [Class 40 (vi)] In a valve relay circuit producing a time delay, a pentode valve having no feedback resistance in the cathode circuit is arranged in a '"Miller" circuit and has the-relay in the screen-grid circuit so that operation occurs when anode current transfers to the screen-grid after a predetermined time interval. Operation is initiated by closing a contact to complete the screen-grid circuit and the relay may be arranged to break the circuit again subsequently by means of an auxiliary relay. Fig. 2 shows two relay circuits arranged to be operated alternately with time delays depending on the settings of potentiometers R3, R6 respectively. The screen-grid circuit of valve V2 is completed after the first time delay by the operation of relay A which remains energized via back contact A1 and normally closed contact B1. After the second time delay, relay B operates to release relay A and complete the screen-grid circuit of valve V1 again, when the cycle is repeated.

Abstract: 599,299. Two-way transmission. SOC. ANON. DE TELECOMMUNICATIONS. Nov. 6, 1945, No. 29589. Convention date, Sept. 23, 1942. [Class 40 (iv)] [Also in Group XL] In an equalizer 7 for telephonic repeaters, in which a tapped resistance 8 enables the attenuation to be adjusted for lines of different lengths, the same setting of the resistance 8 can be used for heavily loaded as for lightly loaded lines. To this end the resistance 8 is formed as a series of T-sections between terminals 14, 20, Fig. 2, and a switch 15 is closed or open according as the line to be equalized is loaded with 88 or 177 mH per 1800 metres. The resistances are so calculated that the settings of the wiper 16 are the same in both cases for the same lengths of time. In this way, the repeater is equalized for frequencies above the resonant frequency, 800 c/s., of the network. If distortion results at the lower frequencies, a similar resistance 18 with shunt condenser 19 is inserted in series.

To produce a thermopile of the kind in which a set of thermoelectric semi-conductor bodies are sandwiched between a pair of plates which provide appropriate contact bridges between the bodies, the bodies are attached, e.g. by soldering, to plates made in the following manner. A metal support is coated with an insulant such as aluminium oxide or a glass fibre reinforced plastic and a metal plate is secured by adhesive to the insulant. This plate is then covered with photo-sensitive etch-resistant lacquer which is treated by light exposure to provide a surface mask, through which parts of the underlying metal plate are etched away. This leaves a required pattern of contact bridges such that a set of semi-conductor bodies soldered between two such plates constitutes a thermoelectric battery.
