Title: Improvements in or relating to a Method of Joining Metal-Sheets by Automatic Welding and Apparatus for Carrying Out Said Method
IPC: B23K9/02
Filed: 1967-04-03
Abstract: 1,188,681. Welding by fusion. TECHNIGAZ. 3 April, 1967 [6 April, 1966], No. 15056/67. Heading B3R. In welding apparatus for seam welding a lap joint between sheets, the welding torch is guided by means engaging the surface of one sheet to maintain the torch at a constant distance from such surface and by means engaging the edge of that sheet to align the torch with the edge. Metal sheets are lapwelded by first tack-welding and then continuously seam-welding without the use of filler metal. Sheets of thickness 0À012-0À158 in. may be so welded using a torch of the plasma arc or inert gas shielded non-consumable electrode type. The continuous welding of the tack-welded sheets 26, 27, Fig. 2, is effected by a torch mounted on a carriage 3 slidable on rods 8, 9 of a frame having four feet 21, 22, the front pair of which abut against the edge 43 of the upper sheet 26. A pinion 25 driven by a motor 4 on the carriage 3 engages a rack 16 on the frame to traverse the welding torch. At the end of the weld the rack 16 is rotated out of engagement with the pinion 25 and the carriage 3 is returned manually. The torch is carried in a holder 48 adjustably mounted on a bracket 5 pivotable about a shaft 28 mounted in the carriage 3 so as to be axially slidable and non-rotatable. A spring 38 presses the bracket 5 against a shoulder on the shaft 28. Rollers 56 or a slider carried by the lower end of the shaft engage the surface of the upper sheet 26 and so maintain the torch at a constant vertical distance from the sheet 26. The bracket 5 supports rigidly a rod 41 carrying a spring- loaded feeler 42 engaging the edge 43 and pivoting the bracket against the action of a spring 46b so that the torch follows a path corresponding to irregularities in the edge 43.

Title: Improvements in or relating to amplifiers
IPC: G11C11/06
Filed: 1961-04-26
Abstract: 953,395. Transistor pulse-amplifying circuits. SIEMENS & HALSKE A.G. April 26, 1961 [April 27, 1960], No. 15080/61. Heading H3T In a transistor amplifier in which input signals derived from a matrix storage unit are applied differentially between input terminals E to the base electrodes of transistors Trl, Tr2 and the resultant potentials appearing at the collectors of these transistors are directed through rectifiers D3-D6 to the bases of transistors Tr4 and Tr5 so that that of transistor Tr4, which is normally conducting, is sent positive to cut transistor Tr4 off while that of transistor Tr5, which is normally non-conducting is sent negative to switch transistor Tr5 on and produce an output signal at its collector, the differential operation of the amplifier reduces the effects of in-phase interference signals at the input terminals, the effects of such interference signals being further reduced by gating the amplifier to be operative only during the periods when input signals are applied to the input terminals by means of gating pulses applied to render normally conductive transistor Tr3, connected in the emitter circuits of transistors Trl, Tr2, non-conductive. When transistor Tr3, whose conductivity type is different from that of the other transistors, conducts, diodes D1, D2 prevent the bases of transistors Tr1, Tr2 from going negative with respect to their emitters and hence prevent conduction in these transistors. When transistor Tr3 is switched off by a gating pulse, transistors Tr1, Tr2 become effectively connected between supply voltages -U2, +U3 and the transistors conduct. Diodes D7, D8 prevent the collectors of transistors Tr1, Tr2 from going negative with respect to supply voltage - U1.

Title: Automatic carton closing machine
IPC: H04B10/00
Filed: 1963-04-18
Abstract: 1,046,121. Packaging-machines; endless conveyers. LOVESHAW CORPORATION. April 18, 1963 [Aug. 24, 1962], No. 15266/63. Headings B8A and B8C. General.-The top flaps of previously filled cartons are closed and sealed in a machine to which the cartons are supplied on a roller conveyer 9, admitted one at a time on to a continuously moving endless conveyer 27, clamped between transversely movable rails 80, 180, and released to the control of an intermittently operated chain conveyer 59, 159, the flaps being folded by a vertically movable head 142 before gummed tape is applied by wiper arms B, C. The machine deals with cartons of random size but, after the first carton has pre-set the flap-closing mechanism, a pressbutton may be operated to set the machine to close cartons of uniform size, the conveyer 59, 159 then moving continuously. Detailed operation.-The leading carton on the conveyer 9 crosses a lowered gate 12 and breaks the beam of a photo-electric device 138, 139, thereby raising the gate 12 which cuts off the next carton. The first carton carried by the conveyer 27, is arrested by a stop 164 on the currently stationary conveyer 59, 159. A second photo-electric device 140, 141 also operated by the carton, causes the rails 80, 180 to close on the carton which is held between the arm 116 of a sensing device 115 on the rail 180 and a flange 81 of the rail 80. The rails 80, 180 are operated by a pneumatic cylinder 87 through chains passing round sprockets 90-94. The chains are attached to slides 84 184, movable on rods 82, 83, the rails being mounted on the slides. The device 140, 141 also initiates drive to the folding head 142, and the front flap of the carton is folded back by a pivoted arm 146. A switch 149, operated by the arm 146, halts the downward movement of the head 142, energizes the drive to the conveyer 59, 159, and co-operates with a carton width sensing switch 128 to cause an arm 161 to pivot down and fold the rear flap of the carton forwards. The arm 161 is operated when a sensing arm 129 of the switch 128 is released as the carton moves forward. A lug 66-1, on the now moving conveyer 59, 159 trips a switch 135 to apply a clamp 104, holding the rails 80, 180 at their inward position, and release the arm 116 of the device 115, thereby freeing the carton. The next following flight bar 64 of the conveyer 59, 159 carries the carton forward, the rails 80, 180 now serving as guides. As the carton continues, ploughs, e.g. 233, turn over the side flaps and tape from a reel D is applied by the members B, C. The conveyer 59, 159 is stopped when the lug 66-2 trips the switch 135, and the various members of the machine are thereby re-set. The machine operates automatically by means of electricallycontrolled pneumatic circuits.

Title: Improvements in or relating to a load carrying and release device
IPC: B66C1/38
Filed: 1946-05-22
Abstract: 626,465. Automatic release hooks ; hook fastenings. FRIEDER, L. P. May 22, 1946, No. 15481. Convention date, July 20, 1945. [Classes 44 and 89 (ii)] [Also in Groups XXX and XXXIII] An automatic release hook is contained within a telescopic casing which is extended by the weight of the load to tension a spring which subsequently tilts the hook to release the load when the weight of the load is relieved therefrom. As described, a tubular casing 11, Fig. 1, telescopically engages an outer casing 10 having load engaging means 14. The casing 10 carries a pin 17, Fig. 2, which engages slots 20, 21 in the casing 11 and slots 24, 25 formed in bars 22, 23 secured within the casing 11 by a sleeve and pin 28, 29, and pins 26, 27. A hook 30 having a slot 31 engaging the pin 29 has a projection 32 engaging the wall of the casing 10 through a slot 34 in casing 11. A spring 39 is connected between the hook and the casing at 45. Application of the load to the device causes the hook to slide upwards until pin 29 engages the bottom of slot 31, the spring 39 being coupled by loops 42, 43 to allow such motion without tensioning the spring. Continued application of the load produces telescopic extension of the casings 10, 11 and tensioning of spring 39 which tends to tilt the hook out of engagement with the ring 35 but which is prevented from so doing during the initial stage of the extension by engagement between the projection 32 and the casing 10. In the later stage of extension disengagement of the hook is prevented by the strip 37 of the casing 10. The casings are maintained fully extended by a spring catch 46, Fig. 4 Upon being relieved of the load the spring 39 pulls the hook downwards out of engagement with the strip 37 and tilts it to release the ring 35. To reset the device, the ring is attached to the hook and the casings retracted by releasing the catch 46.

Class 120(2) In a machine for processing continuously running yarn, a suction device is disposed near the path of one or more yarns and comprises a tube 18, connected to suction means, extending across the path of the yarn or yarns with an inlet hole 22 for each yarn, a sleeve 21 or sleeves being slidable on the tube so as to cover or uncover an inlet hole or holes. The machine may be one for contracting or stretching yarn under heat, or as in Fig. 1, for applying crimp by false twisting under heat, in which case it includes a delivery package 11, a heating device 15, a false twister 16 and a take up package 20, the suction device being at 18. At doffing, the operative uncovers the appropriate hole 22, severs the yarn below the suction device and inserts the running end into the uncovered hole where it is received until the full package 20 is replaced by an empty one; the operative then cuts the yarn and quickly applies the end to the empty package support. A similar procedure may be used when starting up the machine. Suction is applied to the tube 18 by an air pump comprising a container 25, a fan 23 and a filter 26 which prevents the yarn entering the fan blade. Fumes produced by the heating device may be drawn away by providing another tube between the device and the air pump.

Patent GB-705470-A (GB)
Title: Improvements in the production of sulphonic acids
IPC: C07B45/02
Filed: 1951-08-29
Abstract: Sulphonic acids are prepared by oxidizing the corresponding thiols by means of hydrogen peroxide, or a substance yielding hydrogen peroxide under the reaction conditions, in solution in a lower fatty acid of high concentration.  A "lower fatty acid" is one containing not more than 3 carbon atoms, and "high concentration" means a concentration of at least 70 per cent. based solely on the water and acid present. Preferably the hydrogen peroxide is employed in glacial acetic acid solution and the thiol is added to the solution at a rate which enables the temperature of the mixture to be maintained between 80 and 115 DEG C. The hydrogen peroxide is added in excess.  The excess hydrogen peroxide remaining after the oxidation is complete is decomposed, for example, by a catalyst such as platinized charcoal, manganese dioxide or aqueous formaldehyde.  Disulphonic acids made in this way may be used as intermediates in the production of polysulphonamides as described in Specification 705,427, [Group IV (a)].  In the examples pentamethylene diol is treated with excess aqueous hydrogen peroxide in a solution of glacial acetic acid, the excess hydrogen peroxide is decomposed and pentamethylene disulphonic acid is separated from the reaction mixture.
