Patent GB-1125166-A (GB)
Title: Form no. 3
IPC: H01R13/68
Filed: 1966-04-26
Abstract: 1,125,166. Cam-operated switches. CLANG. Ltd., H. E. AUSTEN, and C. D. HARWOOD. 26 April, 1967 [26 April, 1966], No. 18191/66. Heading H1N. [Also in Division H2] A retainer for a replaceable cartridge fuse comprises a cylindrical member 7 rotatable in an insulating body and having a journal at each end eccentric with respect to the axis of the member so that, when rotated the member acts as a cam which, at its position of minimum displacement towards contacts 15, 17 permits insertion and removal of the fuse and which, at its position of maximum displacement towards the contacts forces an inserted fuse into engagement with the contacts. The contacts 15, 17 are spring clips. Contact 15 is mounted by means of a bevelled spigot 15A to a line terminal lug 14, while contact 17 is clamped by a screw 18 between the body and the line pin 2.

Title: Heat shrinkable components with meltable liner
Inventor: BARTHELL FRANK E
IPC: B65D75/26
Filed: 1969-04-09
Abstract: 1,262,978. Laminate for heat-shrunk-packaging. ELECTRONIZED CHEMICALS CORP. 9 April, 1969, No. 18200/69. Heading B8C. [Also in Divisions F2 and H2] A polymer laminate, used for instance for skin tight packaging and as end caps for tubes and wires, comprises a hollow body 11 of flexible orientated thermoplastic having a heat actuable memory therein, said memory being activable at a temperature above room temperature (78‹ F.) to induce a major shrinkage in said body, and a non-heat shrinkable, unorientated, cross-linkable, thermoplastic, insert disposed within said body said insert having a portion 12 thereof adapted to melt in the presence of the deforming heat and having another portion 14 thereof cross-linked to substantially prevent the melting of said other portion at least at the heat deformable temperature used to activate the memory of said body. As shown, in an end cap 10 for covering and insulating the bared ends of spliced electrical wires the outer shell 11, of modified polyethylene having added thereto a flame retardant, an anti-oxidant, a vinyl stabilizer and an inert inorganic carrier, is extruded in tubular form and is moulded to form the closed end of the cap the shell 11, while being shaped, being treated by electron beam irradiation to provide dimensional stability at elevated temperatures by cross-linking. The cap 11 is then heated and expanded up to not more than 200% of its original diameter, by applying internal air pressure to expand the cap against an external mould, whereupon it is cooled to below, e.g. 275‹ F., so that it sets in its expanded condition. The inner meltable liner 12 is extruded, at the same time, from a thermoplastics material, e.g. a modified polyolefine, which melts at a temperature between room temperature, i.e. 78‹ F., and the shrinking temperature of the material 11. The material of the liner 12 is cross-linkable so that a portion, e.g. 14, Fig. 2, can be cross-linked by high energy ionizing radiation. In use, when the cap is placed over the bared ends of spliced wires, and heated to shrink the outer jacket 11, the portion of the liner 12 not irradiated melts and moulds itself around the wire ends, and the irradiated portion 14, which does not melt, collapses under the compressive force of the outer jacket 11 and forms a dam which prevents extrusion of any melted material out from the cap. The laminate may be in the form of an open ended tube in which case a portion of the inner liner 12 is irradiated at each end. Copolymers particularly suitable for use as the liner 12 are stated to be selected polyolefines, polyvinylhalides, polyacrylates, polysilastic rubbers, polybutadiene rubbers, ethylene ethyl acrylate. The liner may contain a small portion of non cross-linkable materials, e.g. atactic polypropylene. The materials of the tubular laminate may also include colours, anti-blocking agents &c. Other polymers mentioned for the outer jacket 11 are fluorinated ethylene propylene, and polyethylene terephthalate.

Title: Apparatus for Controlling the Consistency of a Mixture
Inventor: EASON DENNIS EDWARD
IPC: G05D11/13
Filed: 1966-04-26
Abstract: 1,157,111. Automatic density control. J. LYONS & CO. Ltd. April 26, 1967 [April 26, 1966], No.18201/66. Heading G3R. Ionizing radiation transmitted through a product being conveyed from a mixer influences a detector to cause variation of the constitution of the product in the mixer in one sense when detector output rises above a predetermined limit, and in the opposite sense when detector output falls below a lower limit. As described, ingredients are mixed to form an aerated cake batter and its density is examined by passing through it ionizing radiation, e.g. from a radio-active strontium source, as it travels along a channel. The electrical output of the ionization detector is applied through a feedback type chopper amplifier and a variable time constant circuit to biased transistor relays 21, 22, Fig. 3, one or other of which operates if the density gets beyond upper or lower limits respectively. This causes a corresponding relay 31 or 32 to actuate an electromagnetically operated stepping motor 42 in the appropriate sense to restore the density between the predetermined limits by adjusting a valve in the air supply to the batter or otherwise varying the supply of one of the ingredients. A continuously running motor 39 operates contacts 33, 34 to cause intermittent operation of stepping motor 42 at intervals equal to the time which elapses before an adjustment is detected by the ionization gauge.

Abstract: 1281607 Welding by pressure CATERPILLAR TRACTOR CO 16 April 1970 [21 April 1969] 18241/70 Heading B3R In a process for friction welding aluminium to copper the workpieces are first treated mechanically or chemically to remove oxides from the weld surfaces and are then urged together while undergoing relative rotation at surface speeds of from 700 to 3300 feet per minute peripherally; the pressure applied may be constant and within the range 12,000 to 21,000 lbs. per sq. inch or alternatively may be applied in two steps, the range initially being 1000 to 10,000 lbs. per sq. inch and subsequently (when the surface velocity has fallen to about 200 ft. per min.) 16,000 to 25,000 lbs. per sq. inch. The energy transfer is in the range 2500-20,000 ft. lbs. per sq. inch and welding may be effected by the inertia welding process. In apparatus for performing the invention the first workpiece WP1 is driven from motor 26 through an hydraulic transmission 28 including a pump 30 of variable output and a motor 32. The second workpiece does not rotate but is axially movable by means of hydraulic ram 20.

Abstract: 1,002,117. Endless conveyers. GEO. J. MEYER MANUFACTURING CO. May 4, 1964 [Dec. 3, 1963], No. 18350/64. Heading B8A. Bottles being fed from a conveyer F via conveyers D, B, and 10 to a labelling machine R are maintained in the smooth flow condition shown in Fig. 4, in a convergent section C and are prevented from assuming a jammed condition (Fig. 3) by stopping the flow of bottles in the section C by the action of a detecting finger 49 whenever a normal rate of feed of bottles from the conveyer F drops below a predetermined amount. The finger 49 may operate a switch S1 (Fig. 12) so as to deenergize a solenoid and so project a stop 45 into the path of the bottles. Alternatively, the operation of the finger 49 may result in stopping the conveyer 10. When the flow of bottles in the section C has been stopped, the accumulating bottles actuate a feeler 59 which results in stopping the conveyer D. This acts as a friction brake on the flow of bottles advancing on the conveyer F. There may be a series of conveyers fed from a single or double inlet and themselves feeding a series of respective labelling machines (Figs. 5-11, not shown).
