A catalyst may be added to the silicone rubber resin before the conductive particles are added, and the mixture then cured in a mould, under compression if conductive pads are required. The connector may be made from a strip of beryllium copper with fingers 7 along one edge and finger (8) Fig. 3 (not shown) along the opposite edge, and the strip then bent into a U-shape. Alternatively it may be a planar connector with tapering fingers (12) Fig. 4 (not shown) fixed to the substrate by an acrylic adhesive.
Patent GB-550552-A (GB)
Title: Improvements in or relating to circuits including instrument type relays
IPC: H01H47/36
Filed: 1941-09-18
Abstract: 550,552. Electromagnetic relays; photo-electric circuits. SANGAMO WESTON, Ltd. (Weston Electrical Instrument Corporation). Sept. 18, 1941, No. 11959. [Class 38 (v)] [Also in Group XL] A sensitive instrument - type relay controlled by current from a source 2 is adapted, when its magnetic contacts 4, 5 engage, not only to complete a circuit from a source 7 to a load 8 but also to complete or prepare a resetting circuit 9. In the form shown in Fig. 1, the strong resetting current is in parallel with the load and immediately passes through the coil of the relay to forcibly open the contacts. This breaks the circults from the source 7 so that the contacts reclose and an intermittent action ensues so long as the control current 2 tends to close the contacts. In a modification, Fig. 3 (not shown), the relay pointer moves between two contacts and there are two sources for sending resetting currents in opposite directions through the relay coil. In another modification, Fig. 2 (not shown), to avoid the resetting current passing through the control source 2, the relay has two coils one for the control current and one for the resetting current. Isolation of control and resetting currents may also be effected by a bridge arrangement and Fig. 6 shows two relays arranged in series in a bridge in a system operated by variations in light intensity. The relays are such that one tends to " open " when the other " closes." Closure of a relay prepares a resetting circuit which is completed when the other relay also closes. The resetting current then flows through both relays and resets them both. As darkness approaches, current from a photo-electric cell 2' diminishes and relay 3 closes its contacts. This completes a circuit from source 7 to relay 8a which turns on artificial illumination and also produces a voltage drop across a resistance 21. When daylight approaches, relay 3<SP>1</SP> closes allowing the voltage across the resistance 21 to send a large current through both relays as shown by the dotted arrows and opens them. This cuts off the large current and relay 3 remains open while 3<SP>1</SP> recloses. A similar action occurs when darkness approaches again, relay 3<SP>1</SP> remaining closed until relay 3 also closes.

Title: Method and apparatus for the production of Tubular Film
IPC: B29C48/10
Filed: 1968-03-12
Abstract: 1,190,472. Producing tubular films. MITSUBISHI PETROCHEMICAL CO. Ltd. 12 March, 1968 [15 March, 1967; 11 Sept., 1967], No. 12039/68. Heading B5B. In an apparatus for producing a tubular film by melt extruding a synthetic organic thermoplastic polymeric material through an annular die 2 to form a tubular film 3 (Figs. 2 and 3) and inflating it to a predetermined diameter as shown at 17 by the introduction of a gas at superatmospheric pressure into the interior of the film, the freshly extruded film 3 is cooled in two stages with a gaseous coolant discharged on to the film from an annular cooling device which surrounds the film and is coaxial therewith. The cooling device 5 comprises a coolant feed pipe 18, an annular coolant chamber 11 provided with coolant slots 10 through which the gaseous coolant is blown against extruded film 3 in a direction between the horizontal and at most a 30 degree angle of elevation. The film 3 is thereby preliminarily cooled down to a temperature near the softening point of the film material but not to a temperature below the softening point of the material. The cooling device 5 also comprises a second coolant chamber 15 (Fig. 2) fed with coolant from the supply pipe 18 and provided with slots 14 through which the gaseous coolant is discharged at high speed in the direction of travel of the tubular film, the path of travel of the coolant discharged from slots 14 being between a direction parallel to the axis of the tubular film and at most 30 degrees of inclination towards the axis of the film. An annular film expanding chamber 13 (Figs. 2 and 5) is located between annular chambers 11 and 15 and is maintained at a reduced pressure by suction produced by the discharge of gaseous coolant through the slots 14 of the chamber 15. As a result a preliminary expansion is imparted to the portion of the film passing through the chamber 13. The preliminarily inflated tubular film is then cooled rapidly with the gaseous coolant discharged from the slots 14 of the coolant chamber 15 to a temperature below the softening point of the film material while the film is simultaneously further inflated to a predetermined extent by a pressurized gas confined within the tubular film. As shown in Fig. 4, which is a plan view of the device shown in Fig. 2 and in Fig. 5, which is a sectional view of Fig. 4 at line A-A, the film expanding chamber 13 is provided with a number of air inlet tubes 19 each provided with a valve 20. The thermoplastic polymeric material of which the film is formed may be polyethylene, polypropylene, polyvinyl chloride, polystyrene, a polyamide, or a polyester.
