Abstract: 977,446. Control of A.C. motors. LOEWE OPTA A.G. Dec. 10, 1962 [Dec. 12, 1961], No. 46442/62. Heading H2J. An unpolarized synchronous motor 1, driving a rotary head assembly associated with equipment for recording and reproducing television signals, is coupled with disc 4 having aperture 5 so that light from source 7 activates photocell 8 once per revolution of the motor. The cell is supplied with pulses from A.C. source 2 through transformer 9 and half-wave rectifier 10. When the half-wave pulses and light pulses coincide, relay 12 is energized to close contact 13 and short-circuit resistor 14 in the motor circuit. If the pulses do not coincide, the relay is de-energized and the motor speed is reduced until the in-phase condition is restored. This arrangement enables the motor to rotate with its rotor locked in a selected one of two possible phase-positions with regard to the rotating field. In another embodiment, a mirror fixed to the motor shaft directs light on to the photocell only when the shaft is in a definite angular position.

Abstract: 1478915 Thermocouples THERMO-COUPLE PRODUCTS CO Inc 4 Nov 1974 [4 March 1974] 47523/74 Heading H1K The surface temperature of a heat-exchanger tube 38 is monitored by a thermocouple assembly welded thereto, the assembly comprising a pair of conductors 51 held in spaced relationship inside a metal sheath 52 by insulating material 53 and forming a fusion weld hot junction 50 where they extend into a side opening in the sheath. The sheath has at this point a welded pad 56 with a knife edge 58 for contacting the tube 38. As shown, the assembly is welded to the tube by fillets along the surfaces forming the knife edge 58. The pad 56 is formed by welding a filler rod (85 or 100, Figs. 24, 26, 29 not shown) along the sheath and the pad is built-up with further weld fillets (Fig. 8 not shown) which are then machined to form the knife edge 58. The filler rod (85 or 100) may have transverse holes to receive the thermocouple conductors 51 thus allowing the hot junction to be made closer to the knife edge (Fig. 31 not shown). The side opening in the sheath is of keyhole shape and the conductors are located therein by a ceramic plug with a fusion weld forming a bridge between the conductors outside the ceramic plug. The hot junction is separated from the tube surface 38 by less than half, and preferably less than a quarter, of the distance from the hot junction to the outside surface of the assembly. The padded sheath may be straight, in an alternative arrangement, when it is welded along the tube 38 parallel to the axis. The thermocouple materials are Fe-constantan and Cr-alumel with a compacted particulate metal oxide insulator.

Abstract: 1407176 Pretreatment of gasifier feed AIR PRODUCTS & CHEMICALS Inc 11 Oct 1973 [12 Oct 1972] 47604/73 Heading C5E A method of feeding carbonaceous particles to a gasifier operating at elevated temperature and pressure includes the steps of providing a slurry of solid carbonaceous particles in water, introducing the slurry into a drying chamber maintained substantially at or above the operating pressure of the gasifier wherein it is mixed with hot gaseous effluent from the gasifier so that the carbonaceous particles without substantial reaction are dried and entrained in the gaseous effluent, substantially immediately separating the dried carbonaceous particles from the gaseous effluent, and introducing the separated carbonaceous particles into the gasifier. The slurry may be preheated, e.g. by heat exchange with steam, hot condensate, or hot gas from the gasifier or independent gas heater, prior to entering the drying chamber. Water used to form the slurry may be fresh water, condensed steam from the gasifier process or boiler feed water. Steam may be added to control the humidity of the gaseous effluent used to dry the slurry. At least one holding tank may be used to provide a reservoir of slurry to be introduced into the drying chamber. A feed stream of the slurry may be provided and the pressure of the feed stream may be raised to above the operating pressure of the gasifier before introduction into the drying chamber. The feed stream of slurry may contain at least 40% by wt. solid carbonaceous material in the form of coal, coke, char, or mixtures thereof in water prepared in a mixing tank or a slurry in water prepared by wet grinding. The gas consisting essentially of water vapour, carbon monoxide and hydrogen, separated from the solid carbonaceous material may be subsequently subjected to a shift step wherein carbon dioxide and hydrogen are produced. The separated carbonaceous particles may be introduced into the gasifier by entrainment in a stream of reactant being fed to the gasifier.
