Abstract: 1315316 Semi-conductors RCA CORPORATION 21 Aug 1970 [29 Aug 1969] 40379/70 Heading H1K A thin film hetero junction diode comprises a n-electrode 32 of a high work function metal, e.g. gold, silver, nickel, chromium, copper, bismuth on an insulant substrate 34, e.g. glass, alumina, beryllia. A thin tellurium film 36 is disposed on electrode 32 and substrate surface 33 leaving exposed a bond pad 38. A crystalline selenium layer 40 is deposited on the tellurium film and a crystalline semi-conductor layer 42 having lattice constant and crystal structure matching that of selenium is deposited thereon. This may be any N-type compound including a Group VI element; e.g. selenides, sulphides or tellurides of cadmium or zinc or the selenides of antimony or arsenic. A superincumbent metal electrode 44 comprises a film of indium 46 covered by aluminium layer 48; a portion of electrode 44 being disposed on a portion of surface 33 to provide a bond pad 50.  The selenium layer is formed by amorphous vapur deposition and crystallization by heating; repeated several times. Alternatively the tellurium film may be omitted and the selenium layer deposited direct on an electrode of nickel, chromium, silver, or bismuth having hexagonal crystal structure. The diode I-V characteristic is given (Fig. 3, not shown).

Film strips are conveyed in and out of a sequence of processing baths formed of a single continuous sheet 11 in switchback configuration, as shown, by an endless belt 12 having a series of magnets 17 spaced along it, the belt being constrained to move against the underside of sheet 11 with the magnets in contact therewith; the separate film strips 21 are each clipped to a block of magnetisable material 19, each block 19 being conveyed along the upper side of the sheet 11 by the influence of a magnet below it. Thus the film strips are conveyed successively through the developer bath 23, the fixer bath 28, and the wash bath 31b, and may pass through a further drying section. The belt is kept in contact with the underside of sheet 11 by passing it over a series of idler pulleys 13. Guides 14 may be provided underneath each bath.

A conveyer system has trucks propelled along a floor by a member 84 of a towline engaging a pin 24 on the truck, the pin having two positions the upper one of which being normally not engageable by member 84; a bumper 70 having arms 71 pivoted at 73 to truck brackets 72, Fig. 3, has two members 76, 77 each with a lower cam surface 78, Fig. 5, co-operating with rollers 80, 81 on a housing 26 which carries pin 24, Fig. 6; the pin is slidably mounted in a sleeve 38 fixed by members 39, 37 to the housing 26; a tube 40 carrying extensions 44 surrounds tube 38 and is slotted to accommodate member 39. The housing 26 is pivoted at 36 to parts 29, 30 of the truck and is biased by a spring 66 to raise pin 24, the fixed sleeve 38 engaging a collar 47 on the pin 24; in this raised position (dotted line, Fig. 5) the pin is clear of pushing member 84 but does not leave the floor slot 85. Rearward movement of the bumper on striking an object allows the rollers 80, 81 to ride up cam surfaces 78. Normally with the bumper in its extended position portions 82 of members 76, 77 engage rollers 80, 81 to hold the housing 26 and hence the pin 24 in its lower position. When a truck is employed to push another truck into an unpowered branch line, the driven tow line is raised at the junction so that the pin 24 remains in engagement with pushing member 84 on rearward movement of bumper 70 which engages rollers 87 on the rear of the leading truck. The pin 24 can be raised by handle 53 having a rod 50 with a yoke, Fig. 2 (not shown), at its lower end co-operating with a collar 48 on the drive pin. A wayside stop 46, Fig. 5, engages extension 44 on tube 40 to raise the pin 24 through collar 47 to stop the truck. In Fig. 12, not shown, the bumper is pivoted to the truck body through upwardly extending arms and is connected to a brake actuating rod.

A vehicle is provided with a mechanically powered refrigeration unit located above and separated from the vehicle propulsion unit, and drive means, including a belt drive, are provided to transmit drive from the propulsion to the refrigeration unit. As shown, the rearmounted propulsion unit is connected through a centrifugal clutch 1, a belt drive and an electromagnetic clutch 7 to an electric motor 6, the latter being connected by a further belt drive to the compressor 2 of the refrigerating system. Thus the propulsion unit drives compressor 2 while the vehicle is in motion and the electric motor 6, which may be connected to an external power supply, performs this function while the vehicle is stationary and the centrifugal clutch 1 disengaged. Thermostatic control may be effected in dependence on the temperature of storage cabinets 9 or of an icecream dispenser 4 by either operation of clutch 7 when the compressor is powered by the propulsion unit or by cutting in or out the electric motor 6 when this is the source of power. Alternatively a thermostatic expansion valve may be incorporated in the refrigerating system. The ice-cream dispenser is powered by the vehicle propulsion unit through a belt drive, a constant speed unit 3 and a flexible drive shaft 5. A sink unit 10 is provided and has a hot water supply heated by the refrigeration system. In a second embodiment the electromagnetic clutch and ice-cream dispenser are omitted and a generator driven by the propulsion unit is provided, while in a third embodiment both clutches are omitted. In the latter embodiment a fan is provided for cooling the refrigerating unit and the separate storage compartments are maintained at different temperatures by the provision of two thermostatic expansion valves in the refrigerating system.

Abstract: 1327531 Treating water MINES DE POTASSE D'ALSACE SA 7 Sept 1971 [8 Sept 1970] 41749/71 Heading C1C A process for sanitizing water comprises continuously maintaining in the water a predetermined minimum concentration of bromide (e.g. Na, Br) and oxidizing the bromide while in the water by hypochlorite ions which are added to, or formed in, the water at a rate necessary to maintain a required antiseptic action in the water, the rate being in response to the continuous measurement of active bromine in the water. The water (e.g. swimming pool, refrigerating system water) may be in a circulating system, part of the water being passed through an amperometric cell which delivers an electric current the intensity of which is proportional to the concentration of active bromine in the water. The electric current is amplified and actuates through an electronic system, means (e.g. a pump or valve) for controlling the injection of hypochlorite, chlorine, gas, chlorinated water or N-chlorinated compound to the water.
