Title: Aspiration device
Inventor: ARNOLD PAUL
IPC: A61M1/00
Filed: 1983-07-08
Abstract: A device for attachment to a disposable syringe to provide an aspiration device is described. The device includes a body member (2) which is clamped to the flange (4) at the free end of the barrel (6) of a disposable or other syringe. A latching part (12) is pivoted to the body member (2) and includes a latching bar (14) which engages over the flange at the top of the syringe plunger and latches this in the closed position. The syringe plunger is attached to a plunger clamping member (22) which is mounted to the distal end of a mounting post (20) by means of a spring (24). Once the latching bar is pivoted away from the plunger flange the spring automatically draws the plunger into its fully withdrawn position to apply a constant suction to a lesion to be aspirated. <IMAGE>

Patent GB-832272-A (GB)
Abstract: 832,272. Turning gear. BENDIX AVIATION CORPORATION. June 21, 1957 [June 27, 1956], No. 19681/57. Class 7(5) An engine starter drive comprises a pinion 2 and sleeve 4 assembly slidably journalled on a power shaft 1 for movement into and out of mesh with the engine gear 3 and driven by a traversing member having splined connections, one at least of which is inclined with the sleeve 4 and a barrel 11 secured at one end thereof to the shaft 1 and provided at the other end with a stop determining the mesh position of the pinion 2, yielding means being provided for biasing the traversing member towards its normal position in the barrel. As shown, the barrel 11 is rigidly mounted on a driving head 7 fixed on the shaft 1 and has an inturned flange 13 against which a flange 14 on the sleeve 4 abuts when the pinion is engaged, the flanges 13, 14 with a ring 15 therebetween also forming a friction clutch to transmit torque from the barrel 11 to the pinion 2 during starting. A pin 19 mounted in an annular collar 16 slidable in the barrel 11 projects into a helical slot 17 in the sleeve 4 and into an axial slot 18 in the barrel. An annular block 21 of rubber is located in the barrel between the driving head 7 and the sleeve 4. Upon rotation of the shaft 1 the pinion 2 is traversed to the right by the pin 19 engaging the helical slot 17 until the flange 14 engages the flange 13; the collar 16 is then moved back against the pressure of the block 21 whereby the clutch is made to operate. When the engine starts, the over-running of the pinion causes the pin 19 to return it to the idle position, as shown, where it is maintained by a spring-pressed detent mounted in the collar 16 and bearing in a groove in the sleeve 4.

Title: Process for magnetic separation of metals from aqueous media
Inventor: GIBBS DUDLEY FRANCES
IPC: G21F9/18
Filed: 1984-12-19
Abstract: Paramagnetic metals are separated from aqueous media containing them in low concentration by first fixing the metals on bacterial yeast or other cells so as to render the cells magnetic, and then recovering the cells by a high gradient magnetic separation technique. The metal and the cells are contacted in the presence of a compound which is converted by the cells into a product which interacts with the metal and causes it to become bound to the cells. The process is particularly useful for removing low concentrations of highly toxic metals, e.g. uranium, from industrial effluents containing them.

Title: Preparation of calcium fluosilicate for use in obtaining calcium fluoride and pure fluosilicic acid
Inventor: SEIGNEURIN LAURENT
IPC: C01B33/10
Filed: 1986-07-25
Abstract: A fluosilicic acid liquor obtained as by-product of the acid treatment of phosphorus ores, and containing in excess of 10% by weight fluosilicic acid, is brought into contact with anhydrous calcium chloride in a quantity such that there is present one to ten moles of CaCl2 per mole of H2SiF6, at a temperature not exceeding 50 DEG C,whereby calcium fluosilicate dihydrate CaSiF6.2H2O is precipitated almost quantitatively, and the latter is dried at a temperature of 120 to 140 DEG C, to convert it into anhydrous calcium fluosilicate CaSiF6. This can be easily decomposed in air at 250 DEG C to 400 DEG C to form solid CaF2 and volatile SiF4, the SiF4 being hydrolysable in the presence of water to give a purified acid solution and silica. 
<??>For concentrations of H2SiF6 in excess of 25% by weight and using 2 to 5 moles of CaCl2 per mole of H2SiF6, the yields of the anhydrous calcium fluosilicate obtained are greater than 94%.

Patent GB-864986-A (GB)
Abstract: 864,986. Spraying fusible materials. METCO Inc. Jan. 30, 1959 [March 28, 1958], No. 3462/59. Class 69 (3). A spray gun for heat fusible materials is combined with an automatic gas control valve system whereby in one position of the valves gas flow is prevented, in another position the flow is metered, and in a further position the full operational flow is permitted. The arrangement is such that to initiate a spraying operation a full flow is provided to purge the gun of combustible mixture, a metered flow then follows for lighting the gun, followed by full operational flow. In Fig. 1 the gun has conduits 3, 4 and 14 for combustion supporting gas, combustion gas, and blast gas respectively, the feed therethrough being controlled by pairs of valves 24-25, 26-27, and 28-29 respectively. Fusible material is fed through conduit 2, combustion gases pass from passages 23 and blast gas is delivered about the nozzle 20. Each of the valves 24, 26 and 28, Fig. 2, is normally held closed by a spring 45 and is opened by a solenoid 48. Valves 25, 27 and 29 are almost identical, but when their solenoids are not energized they do not close completely but allow a metering gas flow to the gun. A switching system is described, driven by a timer motor and comprising six cam-operated switches, one for each valve, and operated so that firstly all the valves are open, secondly valves 24, 26 and 28 are fully open and valves 25, 27 and 29 are closed to their metering position, and finally all the valves are fully open. When spraying articles moving past the gun on a conveyer, switches may be automatically operated to operate the valves to provide the metering flow when no article is in the spraying position. In a modification a single solenoid-operated dual valve replaces each pair of valves. In Fig. 7 each gas conduit 9b has two branches in parallel with valves 24b, 25b and metering orifices 103b, 105b. The valves are identical with those of Fig. 2, and by suitable operation thereof a gas flow as previously described is obtained. In a further embodiment each gas conduit has three parallel branches each with a valve and metering orifice. Hydraulically, mechanically or pneumatically operated valves may, alternatively, be used. A camoperated switch may be included in the system to provide a spark for ignition purposes adjacent the gun nozzle. An electric circuit providing automatic control of the valve system is described whereby the wire feed to the gun is stopped when the gas flow is prevented or reduced.

Title: Gas-fired water heater
Inventor: SCHMEJA BERND
IPC: F23N1/08
Filed: 1987-02-18
Abstract: A gas valve 5 supplying the burner 3 of a water heater is opened in response to water flowing through a venturi 19, the reduced pressure at the venturi acting on a diaphragm 16 coupled to a valve operating rod 18. Opening of the valve is modified by a throttling assembly 11 arranged between the venturi and diaphragm. The assembly (Fig. 2) contains a valve element 22 coupled to a diaphragm 26 and to a spring- biassed piston 24. The valve element closes when low pressure acts on the diaphragm, to allow an initial rapid opening of the gas valve 5 (appropriate for ignition of the burner). A bypass opening 25 then operates to provide a slower subsequent rate of supply. <IMAGE>
