Abstract: 803,499. Cable insulation. RHEE ELASTIC THREAD CORPORATION. July 27, 1956 [Jan. 3, 1956], No. 23218/56. Drawings to Specification. Class 36. [Also in Group IX] An electric conductor is insulated by a covering thread which, even when decomposed by heat, will leave an effective dielectric residue. The thread comprises a continuous core of one or more filaments of a silicone rubber, e.g. cured polydimethyl siloxane, and a sheath therefor of glass fibres. The sheath may comprise one or more glass threads wound, wrapped or braided about the core, e.g. two glass threads are wound helically around the core in opposite directions, one over the other. The glass fibre may be coated with abrasive-resistant materials such as a silicone, polyurethane resin, polytetrafluoroethylene or polytrifluorochloroethylene and/or the finished sheath may be so coated. One or more covering threads may be applied to a conductor by winding, wrapping or braiding, e.g. a conductor of tinned copper, iron, nichrome, aluminium, silver, or platinum has a flexible insulation covering formed by helically wrapping two threads thereon, one over the other and in opposite directions. The threads may be applied to a conductor before or after other wrapped or extruded sheaths or coatings of insulating materials such as varnish, rubber or synthetic resin.

Abstract: 704,799. Thermally-actuated valves. ROBERTSHAW-FULTON CONTROLS CO. Oct. 10, 1951, No. 23638/51. Class 135 A combined temperature and pilot flame failure control apparatus for fluid-fuel burning appliances is similar to that described and claimed in Specification 703,454, but the thermal diaphragm moves on an axis normal to the valve axis. By rotating a plug cock 18 to open a pilot fuel supply and depressing the handle 22, Figs. 4, 5, a pilot valve 54 is opened by a rod 30 and lever 68. On igniting the pilot jet heating a phial connected to a diaphragm 122, Fig. 13, the diaphragm through a bell-crank 128 and an override spring 138, depresses a lever 140 to a stop 70 and holds the pilot valve open which allows the handle 22 to be released and the cock turned full on. The lever 140 also pivots a lever 102 about, or brings it into contact with, the end of a rod and tube thermal element 98, 100, responsive to the temperature of the heated medium which may then operate the fuel control valve 78 biased to close by turning the lever 102 and a contacting lever 104 pivoting on the head 112 of a temperature-setting screw 114 and acting on a valve head 90 and snap-acting mechanism 84-86, Should the pilot flame fail, the diaphragm contracts and allows the valves 54, 78 to close.

Presses; l i m i t i n g stroke of press; relief and safety devices for; ram retracting-devices; pressure-producing apparatus; working valves.- A press ram or head 21, Fig. 1, is caused to perform its working stroke by means of a piston 24 operated from a cam, crank, eccentric, &c., and working in an hydraulic cylinder formed in the ram, ports 28, 29 being closed by a valve 30. When the ports are opened, the piston reciprocates idly in the ram, which is retained at the top of its stroke by springs or b a 1 a n c e weights, the top position being determined by an adjustable stop 44. The valve-operating mechanism comprises a pedal-operated lever 40 carrying set-screws 42, 43 and levers 37, 32. In the event of excessive pressure, a spring controlled plunger 50 opens the valve by means of collars 531. In a modified form, the hydraulic cylinder is closed by a cover constituting an oil reservoir 551, Fig. 10, a safety valve 73 is provided, and the valve 30 is disposed in the ram. During the upstroke the valve is opened by a lever 37 contacting with a trip 60 carried by the adjustable stop 44, being afterwards closed in the top position by a finger 631 on a cam-operated lever 63. The lever passes through a slidable rod 64, which may be withdrawn from the cam by a pedaloperated lever 70 so that the valve remains open. In a further modification, the ram 21 is arranged in a fixed cylinder 77, Fig. 18, communicating with the cylinder of the piston 24.

Abstract: 1493453 Extrusion-slow moulding D E M OSSBERGER [trading as OSSBERGER TURBINENFABRIK] 30 May 1975 [1 June 1974] 23673/75 Heading B5A In a method of moulding a hollow article, thermoplastics material is extruded from a tubular die against a draw-off device which is removed from the die as extrusion continues to form a tubular preform which is then inflated within a mould. The wall thickness of the moulded article is dependent on three apparatus variables, namely the discharge rate of the plastics material from the die, the cross-section of the tubular die and the rate at which the draw-off device recedes from the tubular die and two of the said three variables are simultaneously altered during the production of the preform in accordance with the desired contours and/or wall thickness changes of the hollow article.

A passage (or passages) 26 leads from the huddling chamber 22 to a back pressure chamber comprising the interior of the extension 13a and an upper chamber 9 between the cover 10 and the cover of the extension 13a. In the closed position of the valve, a cylindrical enlargement 28 on the spindle 12 closes the orifice 11 but in the full open position, a shoulder 27 on said enlargement occupies the orifice 11 and pressure fluid can escape through the passage then available, said passage being constricted and pressure built up in the back pressure chamber when the valve commences to return to its seat. The lower abutment 18 of a spring 19 engages a shoulder 16 on the spindle 12. The upper abutment 20 is adjusted by an externally threaded sleeve 20a held in the yoke 7.
