Title: Improvements relating to a Connector for Electric Welding
Inventor: BISHOP RONALD
IPC: H01R11/30
Filed: 1966-06-21
Abstract: 1,176,167. Welding by fusion. BISBELL ENG. Ltd. 22 Feb., 1967 [21 June, 1966], No. 27669/66. Heading B3R. [Also in Division H2] A connector for use in electric welding comprises a body for engagement with a ferromagnetic article to be welded, means for connecting the body to an earth line and a magnet formed of an anisotropic, non-conductive, ferrite material carried by the body to cause the latter to be attached to the article. A rectangular frame of brass or aluminium has side walls 11, 12 and end walls 14 which define an opening 15 in which is accommodated a closely fitting non-conductive ferrite magnet 16. Plates 17, 18 of mild steel are riveted to each other through the walls to contact the magnet and a boss on the frame has a blind axial bore for receiving an earth cable while a tube 22 of insulating material is secured over the boss to form a handle. In use when a tube is to be welded to an article the edges 26 of the plate 17, 18 are placed in contact with the article and the tube is brought into contact with the rounded edges 24, 25 of the plates 17, 18 which project beyond the frame as in Fig. 3. In the welding of a small diameter tube to an article the major surface of plate 17 or 18 is placed in contact with the article and the tube is located in a pair of notches 27, 28 in the edges of the plates 17, 18 as shown in Fig. 2.

Title: Throttle valve control mechanism
IPC: F02D9/00
Filed: 1957-09-03
Abstract: 863,984. Regulating. TELEVISION ASSOCIATES Inc. Sept. 3, 1957 [Sept. 10, 1956], No. 27721/57. Class 7(6). [Also in Group XXXI] A throttle valve 22, Fig. 1, actuated by an accelerator pedal 24 may be held in any preselected position by an electromagnet 36 which on energization holds stationary a sliding member 40 connected by a linkage 42 to the throttle valve lever 46, a resilient connection 50 in the linkage 42 permitting further opening of the throttle valve by the accelerator pedal when the locking device 36 is operative. The electromagnet 36 is energized by momentary closing of a button switch 117, Fig. 7, which energizes a relay 110 to close the electromagnet circuit 104, simultaneously completing a holding circuit 120, 122, 124, 114, for the relay 110 so that this relay remains energized when switch 117 is broken. Depression of the brake pedal 90, Fig. 1, causes energization of a relay 126 to break the holding circuit 120 and de-energize the electromagnet 36 to release the throttle valve and permit it to close. The electromagnet 36 may also be rendered inoperative by a manually operated switch 130 or by a relay 128 operated when the horn is operated. Green and red lights 109, 134, are lit when the locking electromagnet 36 is inoperative and operative respectively. To permit partial closing of the throttle valve when the locking mechanism 36 is in operation, the connection between the member 40 and link 42 may include a lever 70, Fig. 6, having an arm 72 connected to an armature 79 cooperating with two solenoids 80, 82. During normal operation the solenoid 82 is energized to hold armature 79 to the right as shown in Fig. 6, but depression of a switch 164, Fig. 7, breaks the circuit of solenoid 82 and completes that of solenoid 80, whereby armature 79 is pulled to the left to rotate lever 70 and move linkage 42 to close the throttle valve 22 regardless of the action of the locking mechanism 36. Release of the switch 164 restores armature 79 to its normal position and the throttle valve returns to its preselected open position.

Abstract: 1,254,442. Surface finishing. INTERNATIONAL TECHNICAL SERVICES Ltd. 12 Sept., 1969 [12 June, 1968], No. 27870/68. Heading B3D. A workpiece is treated with an abrasive or polishing substance in a reciprocating vessel 10 whose maximum vertical speed in one direction is greater than that in the other. Ceramic or metallic abrasive, rouge, etc., may be charged into the vessel 10 with a batch of workpieces, or an abrasive blast may enter the vessel 10. Wet or dry treatment may be performed, and vacuum may be applied to the vessel 10 to induce the abrasive blast and/or remove detritus, etc., while a number of separately chargeable compartments in the vessel 10 may allow separate simultaneous processes. The vessel 10 is reciprocated on guide rods 18 by means (not shown) such as a pneumatic ram connected to a ring 21, the downward velocity being greater than the upward velocity, while a rubber pad 24 on a base 23 acts as a shock absorber. The velocities may be controlled by a piston attached to the vessel 10 sliding in a hydraulic cylinder (not shown), a valve in a hydraulic by-pass allowing more rapid flow from bottom to top of the cylinder than vice versa. Alternatively, the actual path of vessel movement may be generally helical, achieved e.g. by imparting a helical form to the guide rods 18.

Title: Process for dyeing webs of textile material
IPC: B41M5/382
Filed: 1972-06-16
Abstract: 1392390 Dry dyeing and optical brightening of webs of textile material SUBLISTATIC HOLDING SA 16 June 1972 [18 June 1971 24 May 1972] 28394/72 Headings D1B and DIP A process for the continuous dyeing or optical brightening of webs of textile material made of synthetic fibres comprises dry heating the webs at 175-220C in contact with a flexible support uniformly coated or impregnated with a uniform layer of a dyestuff or optical brightening agent sublimable or vapourizable at the said temperature, either the temperature or both the temperature and the duration of the dry heating being constantly regulated to maintain level transfer of the dyestuff or optical brightener from the support onto the web. A central control mechanism is used to adjust the temperature and, when desired, the heating duration, and such a mechanism will generally have switch positions which correspond at least to the desired number of shades of colour. It is also possible gradually to alter the duration of the heating, which preferably can be repeated any number of times so that a spectrum of intensities of colour is obtained. Striped patterns may be produced in this way, and these may also be obtained by temperature variation. Level dyeings of any desired shade of colour may also be produced from only one sheet uniformly coated or impregnated with the colour. Thus a dark colour may be used to produce dark, medium and light shades. The process is preferably performed on a machine which has a rotating surface such as a roller which is permeable to air and is connected to a vacuum device. In such machines flexible supports which are either impermeable or permeable to air can be used and in the latter case it is advisable to use a device which creates sufficient vacuum to draw the pervious paper onto the textile web. In such machines the evacuated cylinder may be provided with several heaters disposed across the width of the dyeing surface. British Specification 1312529 describes one machine of this type. It is preferred that the air-permeable cylinder has a large number of perforations, preferably at least 3 per sq. cm., and a cylinder made from foam-like bronze is particularly suitable. The perforated cylinder may be provided with a heat-resistant coating e.g. made from fabric or fleece materials. The flexible support is preferably of paper or aluminium and is coated by known methods. A paper support may be coated with a varnish to make it impermeable to air. Heating may be by infra-red or high frequency irradiation. Polyamide, polyester (e.g. linear polyesters such as polyethylene terephthalate), polyacrylonitrile and polypropylene fibres may be dyed and the process is particularly suitable for dyeing knitted fabrics or tightly packed materials such as carpeting, velvet or imitation fur fabrics. 'Disperse anthraquinone and quinophthalone dyes are used in the Examples.
