Patent GB-2441633-A (GB)
Title: Control valve to prevent backflow in gas lift applications
Inventor: LEMBCKE JEFFREY JOHN
IPC: E21B34/08
Filed: 2007-08-29
Abstract: A control valve 100 is used in conjunction with a gas lift valve downhole for selectively closing a flow path through a wellbore in a first direction to prevent backflow of gas or fluid from production tubing to an annulus. The control valve comprises a flapper check valve 150 which is allowed to close when a flow tube 155 is shifted against the bias of a spring 130 by a force acting against a piston surface 125 attached to the flow tube 155. The force is created by back pressure acting on closed hinged flaps 120 of the piston surface 125 when the force of a gas pressure which acts to open them is less than a biasing force to close them.

Title: A method of dicing wafers to give high die strength
Inventor: BOYLE ADRIAN
IPC: H01L21/78
Filed: 2008-04-18
Abstract: A semiconductor wafer, having a first face including active devices and a back face opposed to the first face, is mounted on a tape 2 supported by a wafer carrier 5 with the back face of the wafer accessible. The wafer is thinned by removing material from the back face to form a thinned wafer. A back face of the thinned wafer is etched with a spontaneous etchant such as XeF 2 while the wafer is still on the wafer carrier, at least to reduce defects generated in thinning the wafer, to produce an etched wafer 12. The etched wafer is diced while still on the wafer carrier to form dies with a high flexural strength. Spontaneous etchants which may be used include those consisting of a noble gas (for example neon, xenon and krypton) and a halogen (for example fluorine, chlorine and bromine), or interhalogens.

Patent GB-699284-A (GB)
Title: A method of de'gumming fatty oils
IPC: C11B3/06
Filed: 1952-04-23
Abstract: Fatty oils containing a large proportion of gums are de-gummed by treating the oil with a 5 to 25 per cent soap solution.  The soap entrains the gums into the aqueous phase which is separated off, e.g. in a centrifuge.  The treatment is preferably carried out at a temperature of 70 DEG  to 95 DEG  C. so as to avoid emulsification and to reduce the viscosity of the mixture. Emulsification may also be avoided by using a soap solution containing an electrolyte, such as sodium sulphate, sodium chloride or soda.  Either a ready soap solution may be added to the crude oil or the soap solution may be formed in the oil itself by adding alkali lye to it which reacts with the free fatty acids and thereby produces soap.  In the latter case the lye is of 0.1 to 0.5 normal strength, which produces a soap solution of the specified strength.  In using a ready soap solution, there may be used the soap obtained in refining fatty oils with lye after suitable dilution with water.  Fatty oils treated may comprise soya oil, peanut oil, and particularly hot-pressed linseed oil. The soaps specified comprise palm oil soap, linseed oil soap, and coconut oil soap.

Abstract: 1,033,891. Landing and launching platforms for aircraft. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. June 17, 1963 [March 16, 1962], No. 10281/62. Heading B7G. A vehicle for launching and landing an aircraft 33 comprises a launching beam 6 pivoted at the rear end of a truck chassis and movable from a horizontal to an inclined position by a jack 10. Two pairs of arms 16, 18, pivotally mounted at their lower ends on the chassis support therebetween flexible bands 24, 26 serving as landing cradles. The cradle ends are connected to cables 28 passing over pulleys 31 on the arms and controlled by winches 30. The aircraft 33 is jet-propelled, the jet nozzles being rotatable to deflect the jet, and is radiocontrolled as disclosed in Specification 10283/62 to permit it to be accurately landed on the vehicle. For a landing operation, the beam 6 is in its lower position, Fig. 1, and the winches 30 tightly stretch the cradles 24, 26. The aircraft is brought to a position a little distance above the cradles and is then lowered slowly on to them, the shock being taken by absorbers (Fig. 4, not shown), permitting an inwardly swinging of the arms 16, 18. The winches are operated to pay-out the cables 28 and lower the aircraft towards the beam 6. After the aircraft is supported by the beam through the interposition of launching shoes 38 the cradles are withdrawn and the beam may be raised (Fig. 2, not shown), for a further launching of the aircraft.

Abstract: 1466573 Automatic control of film processing chemicals LOGETRONICS Inc 7 March 1974 10365/74 Heading G3N A film processor includes a control circuit for controlling the supply of fresh developer to the processor in accordance with the total area of image processed and its density. In the apparatus shown in Fig. 1 a photo-electric arrangement senses the area and density of black on the film as it passes from the wash tank to the drier and an integrator in the control circuit integrates this signal either until it reaches a predetermined level or for a given time and the valve 1 is opened to supply fresh chemical to the developer tank. The circuit shown in Fig. 4 allows the sensor signal to be integrated for a time determined by timer 22 and then the control relay 24 operates to additionally connect the reference supply 25 to the integrator which causes the integrator output to fall until the outputs of level detectors 16, 20 are the same so relay 18 operates to short circuit the integrating capacitor which zeroes the integrator and resets the system. The control relay 24 also operates contacts 28 to operate valve 1 controlling the supply of fresh chemical. In the operation of this control circuit the control relay will be closed for a time which depends on the level of integrator output when the set time expires and is extended when there is a sensed signal present.

[Also in Division F4] In making a heat exchanger element having two metal plates spaced apart by one or more metal spacing members, the member or members is bonded to the plates by continuous uniform metal to metal bonds produced by detonating an explosive layer on one of the plates. Metal plates 1, 2 are spaced by C-shaped members 3 which contain deformation resisting steel members 7 and plate 2 is spaced at least 0À001 inch from members 3 by metal particles 6 or by projections on the plates or members. A layer of polystyrene is placed between the plate 2 and an explosive layer 9 and the latter is initiated by a line wave generator 10, the detonation proceeding through the layer to result in continuous uninterrupted metal to metal bonds between the plates and members 3. The explosive should have a detonation velocity not greater than 120% of the velocity of sound in the metal layer having the highest sonic velocity and must be at least 1200 metres per second. The spacing members may be of Z- or I-section or may be formed by a ridged continuous member or by C-section bars back to back. The heat exchangers may be of the following metals, aluminium, steel, iron, titanium, niobium, chromium, cobalt, nickel, beryllium, magnesium, molybdenum, tungsten, tantalum, vanadium, zirconium, silver, platinum, copper or gold, each layer may be of single metal or alloy of individual metals or either layer may be composed of two or more layers. The two plates may be bonded simultaneously to the spacing members. Specification 878,196 is referred to.
