Patent GB-602106-A (GB)
Title: Improvements in or relating to control systems for electric resistance welding
IPC: B23K11/24
Filed: 1945-06-12
Abstract: 602,106. Control systems for resistance welding. BUDD MANUFACTURING CO., E. G. June 12, 1945, No. 14839. Convention date, June 23, 1944. [Class 38 (iv)] A resistance spot welding system includes means sensitive to physical changes in the work piece during a welding operation to terminate the flow of welding current upon the attainment of a " normal " weld. The system may also include means for preventing a weld when a preceding weld has been abnormal. In the system shown, the change in amplitude of supersonic vibrations received by a Rochelle salt crystal 35, after transmission through the work-piece 4 from a similar crystal 36 excited by an oscillator 37, is utilized to terminate the weld at the correct instant. The crystals are mounted in the welding electrodes 1, 2 which are supplied from a source 6 through transformer 11 and ignitrons 8, 9 having excitation circuits 16 controlled by a timer 23 and phase shifter D. The pick-up by crystal 35, after amplification at 38, controls an elliptical and normally obscured trace on an oscilloscope screen 41. Upon the attainment of a normal weld the increase in attenuation of the supersonic vibrations traversing the work piece reduces tye input to the oscilloscope and a portion of the trace becomes visible, the emitted light actuating a photo-electrically controlled relay 53 which closes contacts 57 in the phase shifter to render the ignitrons 8, 9 non-conducting. If, due to inadequate or excessive welding current, the oscilloscope trace does not become visible, relay 53 remains de-energized and a gong 79 sounds continuously. Contacts 73 of a relay 61, which normally drops out upon pick up of 53, also remain open and render the initiating switch 71 ineffective to re-energize relay 72, which has normally open contacts 77 in the timing circuit 23. A resetting switch 91 must be operated manually before a further weld can be effected. Specification 602,095, [Group XXXVI], is referred to.

Convention date, May 17, 1929. Addition to 314,895, [Class 80 (iii), Linkwork &c.]. [Class 99 (i).] Two hose &c. pipes 20, 21, Fig. 1, are coupled by end members 22, 23, the flanges 1, 2 of which are pressed together, with the interposition of packing 2a, by a pressure-applying device mounted looselv on the member 22 and formed at its lower end with a U-shaped flange 3b, or projections, to receive the flange 1, or projections on the member 23. The said pressure device is formed of two parts 3, 6 which are mounted on either side of the flange 2 and are screw-threaded together. The parts 3, 6 grip a flat ring 7 which is formed with a series of slots 11, Fig. 3, each accommodating a ball 12 bearing on the flange 2, and a series of balls 10 are disposed on the ring to abut against the part 6. The axial distance l between the balls 10, 12 is normally less than the combined radii thereof, but this distance can be increased to apply pressure between the members 22, 23, when the latter are coupled, by a screw 14 which is disposed in the part 6 and is adapted to force the balls 10 against the balls 12. In a modification, Fig. 6, each pipe section is provided with pressure-producing means actuated by a hooked lever 29, 29a through a cam 27, 27a, and the hooks 30, 30a of said levers are adapted mutually to lock in the clamping position.

Title: Improvements in or relating to the combustion of solid fuel
IPC: F23L1/00
Filed: 1942-10-28
Abstract: 579,324. Controlling combustion in stoves &c. C.U.R.A. PATENTS, Ltd., BANGHAM, D. H., BENNETT, J. G., MAYORCAS, R., THRING, M. W., and PIRANI, M. Oct. 28, 1942, No. 15129. [Class 126] [Also in Group XII] In a method of burning solid carbonaceous fuel the rate of heat release and the composition of the combustion gases are independently and simultaneously controllable at will by controlling the rate of air supply for combustion delivered in the form of a jet on to the free surface of a stable bed of fuel arranged and supported to ensure emergence of the combustion gases from the free surface and by so controlling the mean penetration of the jet into the fuel bed that the desired composition of the combustion gases at or near the fuel surface is secured for the desired rate of air supply. The combustion may be controlled so as to produce oxidizing, reducing or neutral gases. The method of combustion is applicable to furnaces of all kinds and to domestic fireplaces and stoves. Fig. 2 shows a crucible furnace to which the method of combustion is applied. The crucible is placed on a support 10 within a chamber 11 through which gases pass from fireplaces on either side of the outlet flue 12. Fuel supplied by hoppers 14, 15 rests upon floor 24, 30 with free surfaces 25, 31 between the floors and depending walls 23, 29. Jets of air are delivered on to the free surfaces of the fuel beds through flared openings 33 in the walls 23, 29. The penetration of air jets into the fuel bed may be varied by varying the velocity of the air jet or by varying the angle at which the jet is directed on to the fuel bed. The walls 23, 29 are provided with horizontal passages 32 in which are arranged rotatable nozzles each having an axial air supply passage terminating in a nozzle opening 36 inclined at an angle of 45 to the axial passage. The nozzle openings 36 deliver through the flared openings 33 and by rotating the nozzles the angle at which the jets strike the fuel surfaces may be varied to vary the degree of penetration into the fuel bed. Fig. 5 shows a continuous muffle furnace in which combustion is effected in a bed of fuel 53 by delivering a jet of air on to the free surface of the fuel from a conduit 61 provided with an elongated air delivery opening controlled by a valve 65 to vary the velocity of the air jet the pressure of the supply of air being maintained constant. The gases of combustion pass through the chamber 52 to the muffle chamber 54. Liquefied ash passes along the channel 71 to a water cooled ashdischarge outlet 72. Specification 579,321, [Group III], is referred to.

Title: Improvements in or relating to the irradiation treatment of products of synthetic linear polyamides
IPC: B29D7/00
Filed: 1957-05-13
Abstract: Fibres and films of synthetic linear polymerization or polycondensation products, e.g. polyamides, polyurethanes, polyesters, polyethylene and vinyl polymers, are brought into a slightly swollen condition and thereafter (before or after drying) subjected to ionizing radiation, e.g. with electrons, neutrons or gamma rays.  By this means heat-shrinkage is reduced without a substantial reduction in strength.  "Slightly swollen" means that the material swollen contains not more than 25% of the swelling agent. The irradiation may take place at normal or elevated temperature, preferably with the material under tension just less than that required for permanent deformation, and preferably after the material has been subjected to any final stretching.  In an example a thread of nylon (840 denier) is swollen in water for 24 hours at 20 DEG C. and then led around two non-parallel rollers in a helical path at 4 metres/minute and under a tension of 50 grams while being subjected to a dose of 5 X 106 rep. by an electron beam.  The shrinking tension and loss of strength of the treated product are compared with those of products (a) irradiated but not swollen; (b) swollen but not irradiated; (c) not treated.ALSO:Products made from synthetic linear polymerization or polycondensation products, e.g. fibres and films of polyamides, polymethanes, polyesters, polyethylene and vinyl polymers, bottles and gear wheels are brought into a slightly swollen condition and thereafter (before or after drying) subjected to ionizing radiation e.g. electrons, neutrons, g  rays.

Abstract: 544,679. Vibration-dampers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 18, 1940, No. 15432. Convention date, Nov. 7, 1939. [Class 108 (iii)] [Also in Group VIII] In washing machines in which a clothes container is rotatable about a horizontal or inclined axis at a slow speed for washing and at a higher speed for fluid extraction, the container and associated parts are supported by two spring systems one of which is only fully effective during washing when the weight is increased by the washing fluid while damping elements which exert a stronger damping effect during washing are also provided. The clothes are placed in a perforated basket 17 having baffles 24 and mounted for rotation on a shaft 25 carried by the non-rotatable tub 11. The basket is driven by a belt 29 from an electric motor supported by the tub. An opening in the front of the basket connects with a glazed cover 15 in the tub 11. The assembly consisting of the foregoing main parts, is supported by springs within an outer casing 46 having a cover 49 giving access to the interior of the tub and basket. The first or main suspension system consists of three tension springs, two springs 51, 52 being arranged at the sides and one spring 53 at the back. The second spring system, which is only fully effective when the weight of the assembly is increased by the washing water, consists of an upper plate spring 91 and two lower plate springs 84, 86 associated with two of the friction dampers which oppose horizontal movement. The upper spring 91 is secured to the upper part of the tub and its ends carry ball connections to frictional rubbing pieces 97 which bear on brackets 95 carried by the outer casing. A similar ball joint and frictional element are arranged between a bracket 82 on the lower end of the tub and springs 84, 86. Spring 86, which is stiffer than spring 84, is entirely out of action when drying. Two. similar friction dampers carried by plate springs 61, 62 are located at the sides of the tub to damp vertical movements. The friction pad 83 is riveted to a closed socket 72 playing on the spherical head 76 of a bolt 75.which secures it to its spring 84. A pair of stabilizers are secured in suitable positions near the wall 12 of the tub 11 spaced appropriately with the motor so as to equalize nearly as possible the natural periods of vibration about several axes through the centre of insertion. The spring support gives an average natural period of vibration of about 86 cycles per minute when the tub is devoid of water, and 107 cycles per minute during washing periods, the spring 86 becoming effective when the tub is charged for washing.

Abstract: 531,391. Valves. SPERRY GYROSCOPE CO., Inc. May 25, 1939, No. 15545. Convention date, June 1, 1938. [Class 135] A control valve for a servomotor particularly of gyroscopic apparatus is a cylindrical member having two semi-cylindrical extensions each of which differentially control a pair of ports on rotation of the valve. Figs. 1 and 4 show the application of the invention to the gyro vertical of an automatic pilot for aircraft. The gyroscope rotor turns on a vertical axis in a case 3 pivoted in a gimbal ring 5 in turn pivoted on a fixed support. An indicating pointer 8<SP>1</SP> visible through a window 9 is pivoted to the ring 5 at 12 and is moved up and down to indicate pitching by a crank pin on one trunnion of the case 3. Tilting of the gimbal ring causes the pointer to turn to indicate the roll or bank of the craft. Tilting of the gimbal ring is also transmitted through meshing gear wheels 15 to a spindle 14 turning in ball-bearings 19, 20 and carrying a control valve 22. This valve has two semi-cylindrical parts 13, 13<SP>1</SP> displaced axially as shown in Fig. 4 of which the part 13 controls differentially the connection between a port 27 leading to a vacuum pump and ports 23, 24 while the other part controls the connections between ports 25, 26 and a port 28 leading to atmosphere. Ports 23, 25 are connected to a pipe 23<SP>1</SP> and to the ports 24, 26 to a pipe 24<SP>1</SP> which pipes lead to the diaphragm chambers 29, 30 of a relay valve 31 controlling the operation of a servomotor 35 actuating the ailerons. To provide a follow-up action the valve casing is rotatably mounted in a bearing 21 and is turned to follow the movement of the valve by a diaphragm 32 subject to the pressures in the pipes 23<SP>1</SP>, 24<SP>1</SP>. The valve controlling the elevator is actuated by a rock shaft 40 actuated by the pointer and comprises a piston valve having two lands 37, 37<SP>1</SP> controlling the connections between the main pump port 48, exhaust ports 51 and ports 46, 47, 49, 50 leading to the relay valve. In this case the follow-up device comprises a ported liner 44 coupled directly to the diaphragm. Specifications 416,813, [Group XX], and 531,388 are referred to.
