Patent GB-1197565-A (GB)
Title: A Continuous Flow Cryometer
Inventor: QUAYLE JOSHUA CREER
IPC: G01N25/04
Filed: 1966-09-08
Abstract: 1,197,565. Measuring liquidus points. J.C. QUAYLE. Sept. 6, 1967 [Sept. 8, 1966], No. 40172/66. Headings G1D, G1N. A continuous flow cryometer comprises a duct 4 through which there flows a liquid, the liquidus point (or temperature at which the liquid is in thermal equilibrium with its crystals) of which is to be continuously measured. The duct comprises flat plates 5, 6 and a temperature measuring device 8 such as a platinum resistance thermometer, surrounded by a thin metal sheath, is located in a space 10 filled with sample liquid from the liquid stream flowing between the plates. A thin magnetic spring strip 11 is maintained in vibration by an electromagnet 14, 15 and sweeps the sample liquid into the space 10. One or both of the plates 5, 6 is cooled until the liquid in the space 10 freezes thus preventing the vibration of the strip 11. The cessation of the vibration is detected by a pick-up coil 12 and the cooling is decreased until the vibration begins again. The temperature of the liquid around the top of the space 10 therefore hovers around the liquidus temperature. The measurement of the liquidus print gives an indication of the purity of the liquid.

Abstract: 946,091. Moulding machines; casting machines. COMPAGNIE DE PONT-A-MOUSSON. Nov. 15, 1961 [Nov. 22, 1960], No. 40907/61. Heading B3F. Apparatus for handling metal moulds or coreboxes having two parts separable on a vertical joint plane comprises a transfer mechanism for passing the mould through a succession of stations and a mould opening and closing mechanism disposed at a fixed stripping station, independent of the transfer mechanism and adapted to firmly grip each mould arriving at the station, open it, close it and return it in the closed position to the transfer mechanism. In a machine for making resin-bonded sand cores, the core-boxes M are passed on a circular path through a moulding station I, a drying oven II and a core-removal station III. Each box comprises two halves, a, b, located by dowels c on the parting plane and which may be locked together by hooked levers 14. The transfer mechanism comprises a vertical pivot 4 which is manually rotated and positively located at each station by a retractable stop D, Fig. 1. The boxes are suspended from the pivot by lugs 89 which engage over pins 6, the lower edges of the boxes abutting the edges of a plate 7 fixed to the pivot 4. At the core removal station the box opening and closing mechanism C comprises two mechanisms P, Q, each comprising a stirrup 22, 28, respectively, vertically movable by a cylinder 20, 26. The stirrups are raised to lift the box slightly by engagement of the stirrups with lugs 17 on the box, and the box halves are unclamped by actuation of the levers 14. The mechanism Q is suspended by flexible strips 25 so that it may then be moved laterally, Fig. 5, by a cylinder 39, taking the core box half b with it, and the core is removed. The box part b is then restored to part a by reverse operation of the cylinder 39, the halves clamped together, the stirrups lowered, and the pivot manually rotated through 90 degrees. The machine may be a casting machine, with two-part metal moulds which are opened and closed at the casting removal station. The transfer device may be arranged to move the moulds &c. other than in a circular path.

Title: Compacted starch and method for producing same
Inventor: KOTT ARTHUR
IPC: C08B30/06
Filed: 1960-11-29
Abstract: <PICT:0944224/C3/1> <PICT:0944224/C3/2> In a process for producing dense co-hesive flakes of starch without added binder a stream of powdered starch is forced between a pair of oppositely rotating rollers, and air is evacuated therefrom in advance of its entry into the bite between the rollers.  Powdered starch may be fed from a flash dryer to a preheater 1 in which its temperature is raised to 90 DEG F. to 180 DEG F., and from which the preheated starch passes via a distributer 2 to a pair of force-feeders 3 and thence to compacters 4 comprising pairs of compacting rolls 18.  In passing through the nip of each pair of rolls 18, the starch is pressed against a de-aerating vane 38 comprising porous plates through which air pressed from the starch passes to a vent pipe 48.  Alternatively deaerating plates are provided at the ends of the rolls.  From the rolls the starch sheets pass to breakers 5, 5, which form coarse fragments which are reduced in size in mills 6, 6.  From the mills 6, 6 the starch fragments are delivered by a belt-conveyer 7 and a bucket-elevator 8 to oscillating screens 9, 9 which deliver particles of the desired size via a conveyer 11 to a packing station 14. The fines are returned by a conveyer 13 and hopper 15, 16 to the preheater 1, whilst over-size fragments are passed via a conveyer 12 to a mill 17 and thence returned to the screens 9, 9. U.S.A.

Abstract: 1,242,062. Artificial arms. MOLINS MACHINE CO. Ltd. 13 Sept., 1968 [15 Sept., 1967], No. 42272/67. Heading A5R. [Also in Divisions G2 and G3] In a fluid pressure system controlling an artificial limb, the system fluid is pressurised by a battery-driven pump whose delivery is controlled in accordance with the system error signal to prolong the battery life. As shown, a pump delivers to passage 22 and slidable valve member 21 is positioned through fluid link 27-25 to connect one of passages 23, 24 to passage 22 and the other to exhaust, thereby positioning pistons 13A, 13B to control arm 15. Feedback to the valve member 21 is provided by cam 16, lever 29 and spring 28. The pump is driven by motor 33 in a circuit powered by battery 34. The motor speed is controlled in response to the position of valve member 21 by the wiper 41 of a centre-tapped potentiometer in the motor circuit. Thus, with the valve member 21 in the neutral position shown, the motor is stationary and the battery power is conserved. The displacement of the pump may be varied instead of its speed. When several systems are supplied by a single pump, the maximum error signal determines the pump speed or displacement. (For Figure see next page)

Abstract: 437,240. Festoons. WEISSING, H., Grimma, Saxony, Germany. April 1, 1935, No. 10096. Convention date, Jan. 22. [Class 93] [See also Group VIII] A cellular festoon is constructed by joining to opposite sides of a central strip or strips, strips which are longer than the central strip but are folded into undulating or zig-zag shape, the joints being made at the inside bends of the outside strips. The central strip prevents complete straightening of the outside strips when the festoon is suspended, thus avoiding excessive flattening of the festoon. Strips of paper b, c, Fig. 2, folded to zig-zag shape with tongues d are placed at opposite sides of a shorter strip e to which the inside tongues are joined. Fig. 5 shows a modification in which two zig-zag strips j, k are joined to a shorter central strip and slots m are made in the strips at one edge whereby that edge can stretch more readily than the other, thus enabling the festoon to hang more gracefully in a curved state. An ornamental sheet r may be suspended by tabs s. The slots m may be cut when the festoon is folded to form a block, flaps may be formed by cutting slots through the block, and the block may have a wavy outline.
