Title: Improvements in or relating to Automatic Friction Clutches
IPC: F16D43/10
Filed: 1968-03-01
Abstract: 1,175,473. Friction clutches. S. MORONE, and G. LINO, [trading as ADIGE SOC.]. 1 March, 1968 [3 March, 1967], No. 10117/68. Heading F2C. An automatic friction clutch comprises centrifugally-acting masses (14), Fig. 3 (not shown), which apply an axial thrust to engage cooperating annular surfaces on driving and driven clutch members, the masses being mounted on levers 10, Fig. 1, pivoted to turn about pivots parallel to the clutch axis and carrying wedging members 11 which during outward movement of the masses co-operate with inclined surfaces 5<SP>1</SP>, 6<SP>1</SP> to provide the axial thrust. The centrifugal force on masses (14), pivots the levers 10 to force the rollers 11 inwardly between the inclined surfaces 5<SP>1</SP>, 6<SP>1</SP> thereby moving clutch plates 5 and 6 away from each other so that friction facing 12 engages casing 1 and clutch plate 7 is clamped between the friction facing 12 on clutch plate 6 and on cover 8. In modifications the gear-wheel 2 is replaced by a sprocket or pulley and clutch plate 7 may be omitted.

Title: Flexible conduit and method of manufacture
IPC: F16L11/115
Filed: 1963-03-14
Abstract: 987,321. Flexible tubes. DAYCO CORPORATION. March 14, 1963 [April 17, 1962], No. 10209/63. Heading F2P. A flexible relatively inextensible externally corrugated conduit comprises an internal reinforcement having axially spaced turns, an elastomeric member embracing the reinforcement and a relatively non-stretchable formedin-place braided fabric cover which embraces said member and exerts a radially inward force against said reinforcement unifying the resulting assembly, the elastomeric member and cover partially surrounding said turns and extending inwardly therebetween. As shown in Fig. 1, elastomeric material 14 is forced from a tube-extruder 13 around a coil 11 of reinforcing material, e.g. rubber-covered metal or plastic, or wholly thermoplastic, and forms the elastomeric tube 16 around a coil 11 driven in the direction of the arrow by known means. The reinforced tube is then led to a braiding machine 17 (the 90 degrees here shown has no special significance) and films, e.g. nylon, cotton &c., wound from spools 18, 19 which are mounted on a rotating ring. Braiding 22 is thus applied to the tube with a compressive force that forces the elastomeric material between the turns of the coil and so produces corrugations. The reinforcement may be helical, as shown, or may be a series of separate rings around a compressible mandrel. Instead of the tube 16 being formed by extrusion an existing tube 26, Fig. 3, may be placed in a vacuum chamber 25, embracing a reinforcing coil 23 on a compressible mandrel 24, and collapsed on the coil, thereby becoming corrugated. As shown in Fig. 6, the ends 30 of two hollow cylinders 27, preferably of the same material as the tube 26, may be inserted in the ends of the reinforcing coil 23 and vacuum applied, after which the tube, so corrugated, and the cylinders 27 are braided, Fig. 7. The product is cut into lengths by severing the cylinders in the middle by a cutter 31. The surface may then be sprayed, from a nozzle 34, with rubber or other plastic material. The inner and outer surfaces of the product may be coated with elastomeric material by dipping, for example. Specifications 761,212, 782,541, 813,700 and 867,836 are referred to.

Title: Improvements in or relating to electron tubes for detecting infra-red radiation
IPC: H01J29/45
Filed: 1964-03-12
Abstract: 1,005,482. Cathode-ray tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 12, 1964 [March 15, 1963], No. 10404/64. Heading H1D. An electron tube for detecting infra-red radiation has a target screen 8 sensitive to infrared radiation and comprising a thin layer 9 of a material having a temperature-dependent electrical resistance supported by a support 10 and provided with an electrode 11, layer 9 being in the form of a film or foil of a polymerized material of low thermal conductivity, the specific electrical resistance (#) of the material being between 10<SP>6</SP> ohm/cm, and 10<SP>16</SP> ohm/cm., and the thermal electrical resistance variation   (1/p #p/#T) per ‹C. being at least 5 per cent in a temperature range between 0‹ C. and 100‹ C. As shown, glass envelope 1 with window 2 contains an electron gun 3 and electrode system 4 terminated by a grid 5. The tube is surrounded by focusing and deflating coils (not shown) for electron beam 7 emitted from cathode 6 of gun 3 and scanning screen 8. Electrode 11 is connected to metal ring 12, signal resistor 13 and direct voltage source 14. During operation of the tube, infra-red radiation 15 is projected through window 2 on to screen 8, and by absorption in either electrode 11 or layer 9 or both is converted into heat. As a result the temperature of layer 9 is locally increased and hence the electrical resistance of layer 9 in the direction of thickness is reduced. When layer 9 is scanned by electron beam 7 the local reduction of its resistance shows itself as a corresponding electric signal across resistor 13. Layer 9 may be of polyacrylonitrile, polyvinyl acetate, polyvinyl cyanurate, polyphosphonitrile chloride or a polychelate. Layer 9 may also contain a filler material which absorbs infra-red radiation and/or is electrically conductive. Electrode 11 may be of aluminium, gold or silver and it may be coated on its side remote from layer 9 with a thin layer which absorbs infra-red radiation and may be a silicate.

Casting.s other than metal; treatment of castings.-Deposits of silicon or mixtures thereof, including alloys and silicides, are sprayed on to surfaces to form a non-electrolytic, anticorrosive coating. The spraying apparatus may be of known type, such as gas blow-pipe, or electric arc or furnace, with or without air blast. The silicon &c. may be projected at high velocity under high pressure, when the particles thereof may be in solid form; if lower velocities and pressures are used, the silicon &c. is heated to a pasty or molten state. The surface to be coated may require cleaning as by sand-blasting and may also be locally heated during coating. When the high velocity and high pressure method is not used, a reducing atmosphere such as nitrogen or carbon-monoxide is preferably used instead of air-blast. When the surface to be treated is unsuitable for direct deposit, a deposit of other material such as lead, tin, copper or aluminium may be first applied, or a flux, such as an alkaline metal or its halide, aluminate, borate, oxide or hydroxide, or aluminium or zinc halide, may be incorporated with the silicon &c. The deposits may be detached from the surfaces coated and form articles per se.

The frequency radiated is about 19, 20, 22 or 24 KHz and is determined by choice of the element 20. Several adjacent units as described may be provided and different frequencies in adjacent units produce beat frequencies having high peak powers. Different frequencies at independently controlled rates are particularly effective. The timing of the on/off square wave is determined by the value of resistor 42. A neon lamp 72 in parallel with the piezoelectric element 20 is illuminated by power from the resonant circuit and also indicates failure of the apparatus.  The apparatus is suspended by a wire 10 from the ceiling. A cylindrical housing 12 contains circuit components and supports a reflector dish 14 having a guard grille 16.
