Abstract: 1289146 Light guides; dew point hygrometers A K AMELKIN N S NIKOLAEV and M M SERGEEV 7 Oct 1969 49274/69 Heading G2J [Also in Division G1] A dew point hygrometer Fig. 1 comprises a sensitive optical element 1 mounted on a backing 6 in turn mounted on a support 5, there being means 2 for projecting a light flux through the element and means 4 for sensing the flux reflected by the element. The optical element is a fibre optic light guide and means are provided for varying and measuring 7, 8, 9, 10, 11 the temperature of a working zone of the element when said zone is placed in a gaseous medium whose humidity is to be measured. The backing 6 has a refractive index less than that of the light guide to enable efficient total internal reflection through the guide, and the support 5 has a refractive index greater than that of a condensate of the gaseous medium formed in the working zone. In operation, the means 2 e.g. a lamp and diaphragm 3 are initiated to project light through the guide to the sensing means 4 e.g. a photo-cell powered from a unit 11, this actuates through amplifier 9 a switch of a thermoelectric cooler 10 provided under the support 5. Drops of condensate formed on the light guide, backing and support intercommunicate the guide and support due to their favourable relative refractive indices which results in a sharp change in the flux reaching photo-cell 4, which accordingly switches off the cooler 10, the process being repeated until the support temperature is stabilized whereby the humidity is read off from the appropriately calibrated thermometer 7. In an alternative embodiment Fig. 2 (not shown) the light guide 1 is made discontinuous in the working zone, the two light guide sections (1<SP>1</SP> and 1<SP>11</SP>) being communicated by droplets of condensate, in operation, so as to give a sharp change in the signal received by photo-cell 4. A similar switching and cooling circuit is also used. The hygrometer is useful for measuring the humidity of dust loaded gases.

Resilient portions 50, 54 of front and rear walls 42, 43 contact the roller and during rotation of the roller; the resilient portion 50 limits the quantity of toner carried by each groove and the free edge of the resilient portion 54 is oscillated by the roller and sweeps the surface 62 of each groove prior to that groove being filled with toner. A seal is formed between the ends of the portions and the end walls 41 by pads 56 e.g. of polyurathane foam. The front and rear walls are adjustable relative to. the end walls. The portions are preferably rectangular pieces of spring steel of À012 inch thick. A shaft 70 extending the front and rear walls rigidly carries a paddle 68, and a counterweighted arm 73 and a magnetic switch actuator 72 are also secured to the shaft. With an adequate amount of toner in the hopper the paddle and arm will remain as shown. However upon a drop in the level of toner below a minimum amount the counterweight will cause the shaft and paddle to rotate and a reed switch 76 in an electric circuit for indicating the absence of toner will be actuated by movement of the actuator. A latch 77 is provided for preventing pivoting of the shaft under bias of counterweight during filling of the hopper.

When the handle 85 is suspended in a bracket 87 on the frame 11, a plunger switch 84 is maintained depressed by a lug 88 so as to close an electric circuit to energize the drive means for the frame 11. The position of the lug 88 is adjustable to sequently the speed of the drive means. The electric circuit includes a variable potentiometer (72), Fig. 4 (not shown), located within the alter the position of the switch 84 and conhandle 85 and which is operatively connected to the switch 84 so that variations in the depression of the switch create corresponding variable speeds in the drive means. An electrical brake 45 for automatically stopping the movement of the frame 11 upon actuation of a switch at a reversing station at each end of the fabric lay to reverse the frame 11 is provided. The brake 45 may be de-energized by manual depression of a switch (146), Fig. 4 (not shown), in the handle 85.

Abstract: 1321571 Processing animal carcases ITT INDUSTRIES Inc (International Telephone & Telegraph Corp) 12 Jan 1972 1446/72 Heading A2U An animal carcase is bled whilst it is suspended by at least one hind leg, and is subsequently inverted to a position with the hindquarters lowermost so that meat tends to drift or settle towards the hindquarters before rigor mortis sets in. As shown, a previously bled, deheaded, eviscerated, and longitudinally split carcase comprises two halves 10, 12 suspended by the hindquarters from a gambrel 40 carried by a hanger 38, which has a lost-motion connection with a roller chain (not shown) by which it is driven along a conveyer rail 14. As the hanger approaches a region where the rail 14 is directed downwardly to cross a pair of rails 22, 24 directed upwardly, the forequarters are attached by cords to hangers 38 on the rails 22, 24 or are engaged by pronged tongs carried by the hangers. These hangers are also driven through lost-motion connections by chains (not shown) but at a higher speed than the hanger on the rail 14 so that the two carcase halves are inverted in the cross-over region, the hind legs being detached from the gambrel during the inversion, and the inverted carcase halves are conveyed by the rails 22, 24 to a cooler or other destination. Another apparatus for reversing carcases comprises a turntable on to which a carcase, suspended by its hind legs, is lowered by a descending portion of a conveyer, the carcase being detached from the conveyer, the turntable rotated through 180‹, and the carcase then being attached by its forequarters to the conveyer to be picked up and removed. Settling of the meat towards the hindquarters may be assisted by subjecting the hangers to repetitive vertical movements, or by using centrifugal force in an arrangement in which the carcases are hung from the smaller end of a truncated conical rotor.

Abstract: 1334238 Measuring liquid level electrically JOSEPH LUCAS (INDUSTRIES) Ltd 19 April 1971 [14 April 1970] 17559/70 Heading G1N A vehicle fuel gauge circuit includes a warning lamp 27 which flashes, under the control of a voltage regulator, when the level of the fuel in the fuel tank falls to a predetermined value. Variable resistance 17 mounted in the fuel tank and whose resistance is determined by the amount of fuel in the tank, is connected in series with a bi-metallic strip fuel gauge 16 and contact 14 of thermally operable voltage regulator 15 across the vehicle battery 11. A bridge network constituted by gauge 16, variable resistance 17 and resistors 29, 30 is supplied via contact 14 and the unbalance voltage applied to the bases of transistors 21, 22 connected as a long-tail pair differential amplifier. If the level of the fuel is above the predetermined level transistor 21 is switched on whenever contact 14 is closed and transistors 22, 26 off, lamp 27 remaining unenergized. When the level is reached transistor 22 becomes conductive and due to feedback via resistor 28 transistor 26 becomes bottomed and lamp 27 energized during the period contact 14 is closed. The lamp thus flashes on and off in synchronism with the closing and opening of contact 14. Transistor 26 may be bridged by a further switch 31 which is closed when the choke is in use or the handbrake on to continuously energize lamp 27. Further switches may be connected in the base circuit of transistor 26.
