Title: Electric liquid level meter
IPC: G01F23/24
Filed: 1967-01-26
Abstract: 1,126,294. Measuring liquid level electrically. PRZEDSIEBIORSTWO HYDROGEOLOGICZNE W WARSZAWIE. Jan. 26, 1967 [Feb. 4, 1966; June 11, 1966], No.3952/67. Heading G1N. In a liquid-level indicating system of the follow up type in which a probe electrode is automatically maintained in contact with the liquid by a reversible electric motor control signals for the motor are transmitted from a sensing head carrying the probe electrode at three discrete frequencies to indicate "raise", "lower" or "stop". The sensing head, Fig. 2, which is lowered into a bore-hole by a cable 12 comprises of a transistor oscillator 2 with a power amplifier 7 which transmits signals back to the surface through the cable 12 and also energizes relays 5 and 6 when their associated probe electrodes 8 and 9 complete a circuit through the water to an immersed electrode 11. The sensing head is lowered until probe electrode 8 contacts the water when relay 5 opens (or closes) contacts 3 to change the frequency of the oscillator to the "stop" frequency. If the water level rises to contact probe electrode 9, relay 6 operates contacts 4 to change the oscillator to the "raise" frequency. At the surface, Fig. 1 (not shown) a pair of motor reversing relays are selectively energized by a frequency discriminator in accordance with the frequency of the signals received from the sensing head. The motor drives both a winch for the cable which supports the sensing head and a position indicator. In another embodiment Fig. 3 (not shown) the signals are transmitted from the sensing head to the surface acoustically.

Abstract: 413,403. Riveting. A.T.S. CO., Ltd., and WYLIE, H. N., 5, Clement's Inn, Strand, London. Feb. 9, 1933, No. 3960. [Class 83 (iv).] A device for drawing and holding together metal sheets, especially sheets to be riveted through lapped joints, comprises a body, and a stem passing through holes in the sheets and comprising two or more members one or more of which may be drawn forcibly inwards to the body, the end of the stem remote from the body being capable of expansion or contraction by operation from the body end of one or more of the stem members. A partially split sleeve 3, Fig. 1, having a collar 5 and an enlarged head 6 is pressed downwards by a light spring 8 and is allowed to contract to be passed through a hole in the work when pressure is applied to a disc 11. On releasing the disc, a strong spring 12 raises the mandrel so that its head 9 expands the split sleeve and then draws the mandrel and sleeve upward together to clamp the lower metal sheet against the upper one. The disc and spring may be replaced by a nut engaging the upper surface of the casing and screwed on a threaded portion of the mandrel. A split sleeve 15, Fig. 3, is carried by a tubular member 15b, which is in screw threaded engagement with the mandrel supporting member 16. On rotation of the mandrel by a bar 21 the sleeve 15 is raised and is first expanded and then clamps the workpieces together. A modification of this form is described in which the screw-thread mechanism is replaced by a spring. In a further modification a portion of the mandrel and of the sleeve are elliptical the sleeve being expanded upon rotation of the mandrel and thereafter raised by spring action. The stem may comprise members 42, 43, Fig. 9, having eccentric projections 42a, 43a, the members 42, 43 being rotatable to bring the projections to the inner or outer position shown in Fig. 10. Cam, lever, or like means may be provided to compress the spring where employed.

IPC: C08J5/22
Filed: 1961-02-06
Abstract: Aquagel structures having ion-exchanging properties are made by casting or spinning solutions containing a film- or fibre-forming polymer and an ion-exchanging resin dispersed therein into aquagel structures, e.g. films and filaments.  The film- or fibre-forming polymer is preferably one containing at least 80% of acrylonitrile, e.g. polyacrylonitrile and copolymers of acrylonitrile with other ethylenic monomers, e.g. esters, amides, acids, alcohols, nitriles and pyridines.  The ion-exchanging resin may be an anion or cation exchanger or a mixture thereof, a chelating resin or an ion retardation resin, e.g. a sulphonated styrene/divinyl benzene copolymer.  In the preferred procedure the ion-exchange resin is dispersed in a water-miscible solvent for the acrylonitrile polymer and then mixed into a solution of the acrylonitrile polymer in the same solvent, e.g. dimethyl formamide, dimethyl sulphoxide, butyrolactone, ethylene carbonate and concentrated aqueous zinc chloride, the resulting mixture being coagulated in water or a dilute aqueous solution of a salt, alcohol or glycerol.

Title: Improvements relating to ingot casting machines
Inventor: WORSWICK ALAN
IPC: B22D5/02
Filed: 1961-02-07
Abstract: 937,513. Ingot casting-machines. ALAN WORSWICK (ENGINEERING) Ltd. May 2, 1962 [Feb. 7, 1961], No. 4502/61. Classes 83 (1) and 83 (4).  An ingot casting machine comprises moulds arranged radially about an axis around which they are continuously rotatable, and means for ejecting each ingot at a position immediately before that at which pouring is effected, each mould incorporating water cooling means comprising a steel tube embedded in its lower part through which cooling water flows. The moulds 12 are mounted on a turntable 4 rotated by a friction-wheel 7 driven by a motor 9, the moulds being supported by trunnions 11, 13. Cooling water flows through the hollow turntable shaft 3 to a header tank 18 from whence it flows through steel pipes embedded in the moulds and returns to a header tank 24 and an outflow 27. The moulds are filled by a pump 29 which delivers to a pivoted launder 32 having an arm 34 which, by engagement with a peg 35 on the table, constrains it to follow the mould during pouring until the arm slips from the peg and is spring-returned to engage the next peg 35 for filling the next mould. The end of the launder is supported on a roller path 37. The pump is immersed in molten metal and when pouring is initiated by a cam on the turntable when a mould is in position, compressed air closes an inlet valve 41 and also forces molten metal to the launder 32. Movement of a float 88 adjusts a reducing valve 83 to give a discharge air pressure dependent on the level of the melt in which the pump is immersed and, by-means of a limit switch, 89, cutting off the compressed air supply when the level falls to a lower limit. A float 93, Fig. 5, is lifted by the melt in the mould and closes an air nozzle 49 when the mould is filled, thereby stopping pouring. Alternatively the level of the metal in the mould may be sensed by a probe to stop pouring or to start a timing clock which will stop pouring after a predetermined time. The roller path 37 is carried by a piston 94 and spring loaded so that the launder and float are raised clear from the mould when not pouring, and lowered for pouring. At the ejection position B a cam and gearing arrangement turns the mould through 180 degrees to drop the ingot on to a conveyer 61, and turn the mould back again for recharging. Stamping castings.-As soon as the ingot has just solidified it is marked by a device comprising a type wheel 68 which is carried by a shaft 67 mounted in a block 66 which is pivoted at 65. The wheel is brought into contact with the ingot by actuation of a cylinder 77 by a valve 78 actuated by a mould as it comes into position, continued movement of the mould rotating the wheel until a pin 69 operates a valve 71 to cause the cylinder 77 to raise the wheel from the ingot and a cylinder 73 to rotate the drum 68 back to its initial position.
