Abstract: 407,725. Fly-papers. WALKLEY, A. R., 19, Fairmile Avenue, Streatham, London. Sept. 20, 1932, Nos. 26128/32, 31752/32, and 1345/33. [Class 5 (i).] A rotating flypaper device comprises a metal member 20 connected to a thread 3 of silk machine twist supporting a disc 26 connected to a metal rod 25 supporting a cross rod 27 at the ends of which are fly-papers 28. A rigid cross member 21 is attached to the member 20 and from this cross member hang two threads 22, 23 carrying a ring at their lower ends smaller in diameter than the disc 26, so that the device is prevented from falling should the thread 3 break. In use the members 26, 25, 27 and 28 are removed from the thread 3 and a weight in disc form is attached to the lower end thereof. The weight is then spun causing considerable twisting of the thread, after which the weight is removed and the members 26, 25, 27 and 28 reattached which will then rotate for a considerable time owing to the damping action of the fly-papers 28. The disc 26 may if desired be used as the spinning weight. Specifications 18717/91, [Class 132], and 2568/14, [Class 3 (i)], are referred to.

Title: Manipulator for Nuclear Fuel.
IPC: G21C19/105
Filed: 1967-06-06
Abstract: 1,163,641. Devices for lifting nuclear fuel elements. COMPAGNIE GENERALE D'AUTOMATISME. 6 June, 1967 [6 June, 1966], No. 26146/67. Heading B8H. [Also in Division G6] When a handling device for nuclear fuel elements is being lowered by a cable attached to a ring 18, Fig. 2, a shuttle 16 to which the ring is attached is in its upper position and an aperture 21 is opposite a tube 20, thus putting a pneumatic chamber, formed by concentric bellows 4, 5, in contact with the atmosphere. Grippers 8 are held in inoperative position by a flange 25 of the shuttle 16, and measurement of the flow rate in a conduit 3 shows that the suspension cable is under tension. When a ring 14 abuts an element further descent of the ring and a piston 13 is prevented. Subsequently the grippers abut the ring and are immobilized and with them the body 7. The shuttle 16 continues to descend until the ring 18 abuts the cover 17, which is signalled by the fall in flow rate in a conduit 12 due to movement of the piston 13. The flange 25 is now clear of the grippers 8 and inflation of the pneumatic chamber 4, 5 forces the body 7 down and pushes the grippers inwards on pivots 9 by means of pins 10. This allows the grippers to move inside the ring 14 and descend until a casing 11 abuts the ring. Supply to the pneumatic chamber is discontinued and a bell member 1 moves down pushing the grippers outwards to engage the fuel element. The device may now be lifted and in so doing the shuttle 16 moves up to machanically lock the grippers and re-connect the orifice 21 to the conduit 20. Whilst the element is held, flow in the conduit 12 should be nil. The temperature of the reactor gas can be measured by a thermocouple 22.

Title: Mixing valve for liquids having different temperatures
IPC: D06F39/08
Filed: 1949-10-13
Abstract: 675,593. Fluid-pressure servomotor-control systems; valves. ROBERTSHAW-FULTON CONTROLS CO. Oct. 13, 1949 [Nov. 5, 1948], No. 26343/49. Class 135. A constant flow mixing valve for liquids at different temperatures comprises a mixing chamber having an inlet for one liquid and an outlet, a constant flow mechanism including a flow responsive device in the chamber for maintaining a constant flow of mixed liquid to the outlet and directly connected to a valve mechanism in the inlet, and a second chamber with an inlet for a second liquid and communicating with the mixing chamber through a valve mechanism operatively connected to a thermostat subjected to the mixture temperature. As shown, cold water entering the nipple 12 passes a check valve 18, thence through the ports 27 controlled by a valve 28 connected to a flow responsive disc 30, around the edges of the disc, through a passage 78, around a thermostat 56, through a passage 84 and electromagnetic valve 99 to an outlet 80. Hot water entering the nipple 36 passes around the edges of a flow responsive disc 41, thence through the ports 45 controlled by a sleeve 42 connected to the disc, and into a chamber 21. The flow from this chamber is controlled by a valve 53 connected to the thermostat. The timing mechanism of a washing machine to which the mixing valve is applied energises a solenoid 92 which attracts an armature 95, opens a pilot valve 96 to release the pressure behind the valve 99 and allows the mixture to pass to the outlet. Should the mixture temperature decrease, the thermostat opens the valve 53 to allow more hot water to flow past the check valve 52 to the mixing chamber where the increased flow closes the valve 27, 28, and reduces the supply of cold water. Should the supply of hot water fail, the bellows 109 opens a switch 106 in the solenoid circuit so that the valve 99 cannot open. The timing mechanism can also open a valve 98 to supply hot water only to the outlet. Specification 659,424 is referred to.

Abstract: 935,862. Feeding webs. WITTON-JAMES Ltd. July 4, 1962 [July 20, 1961], No. 26349/61. Class 100 (1). In web-splicing apparatus in which a replacement reel 7 supported in a three-arm reel stand 1 is brought up to the speed of the running web 6, the dabbing brushes previously employed for splicing are replaced by means 14 provided with jets 17 through which air can be directed to impinge on the running web 6 to cause it to move into contact with the periphery of the replacement reel 7. The splicing means 14, biased against the running web by a spring 33, together with knives 15 for severing the running web 6 from the expired running reel are carried by two parallel arms 11 pivoted at 10. A guide bar 13 and the splicing means 14 presses against the running web 6 to stop it fluttering immediately before the splicing action. The surface 16 of the splicing means 14 is provided with grooves or slots 19 to accommodate tensioning belts (not illustrated). The jets 17 disposed in holes 18 are distributed over the entire length of the guide surface 16 and direct air normally or slightly upwardly to compensate for any drag which the air may produce on the running web. The jets 17 on either side of the slots 19 are angled to direct the air to points on the running web which are normally engaged by the tensioning belts. In operation, air is supplied as soon as the leading end of the replacement web, previously prepared with adhesive strip, has passed the splicing means, so that splicing takes place at the next revolution of the reel 7. The air pressure is controlled so that it is related to the tension of the running web.

Title: Improved method and apparatus for determining and controlling the moisture content of dielectric materials
IPC: G05D22/02
Filed: 1956-08-30
Abstract: 815,000. Electric tests. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. Aug. 30, 1956 [Aug. 31, 1955], No. 26588/56. Class 37. The moisture content of materials whose dielectric constant varies with frequency as well as moisture content is determined by inserting the material between the plates of a test condenser to which two different frequencies are simultaneously applied, and obtaining a voltage which is a function of the ratio of the change in the voltage drop across the condenser when the material is inserted. The invention may be applied to measuring and controlling the moisture content of textile fibres and tobacco. As shown, oscillators 1, 2 feed capacitance bridge 3 with two different frequencies. Arm 4 of the bridge is constituted by condenser 4 between the plates of which the substance to be tested is placed. Initially the bridge is balanced with the material absent. The sample is then inserted and the unbalance voltages appearing at the bridge diagonal are amplified logarithmically at 5, separated by filters 6, 7, rectified at 8, 9 and subtracted at 10, the output from which is thus a function of the log of the ratio of the voltage changes across the test condenser. This voltage may be applied to a suitably calibrated meter 15 to give either an instantaneous or continuous reading of moisture content. This output voltage may also be fed to a comparator 11 also fed with a voltage which is a function of the voltage changes when material of the desired humidity is between the condenser plates. Thus if the output of the subtractor is log V 1 /V 2  and the input from source 12 is log V 1 <SP>1</SP>/V 2 <SP>1</SP>, the output from the comparator is proportional to log (V 1  V 2 <SP>1</SP>/V 2  V 1 <SP>1</SP>) The voltage is amplified at 13 and applied to means 14 which control the drying process. In the case of loose textile materials or slivers moving through a drying zone, for example, the control means may vary the temperature of the drying zone and/or the speed at which the textile moves through the zone.
