Patent GB-2089970-A (GB)
Title: Self-heating, Single-portion Container for Foods and Beverages
IPC: A47J36/28
Filed: 1981-12-09
Abstract: A self-heating container comprises a first container 1 for beverages and foods made of synthetic material and closed at the top by a tear-off foil 9, and a second container 2, made of metal, for housing reagents to provide an exothermic reaction. The second container 2 is divided by a frangible partition 5 into a lower zone containing solid reagents and an agent for priming the reaction and an upper zone 4 containing liquid reagents with an added hygroscopic substance capable of regulating the velocity of the exothermic reaction. Pressure downwards on the container 1 ruptures the partition 5 to start the exothermic reaction. <IMAGE>

Title: Method of Firing Perforating Gun and Simultaneously Recording Downhole Pressure
IPC: E21B47/06
Filed: 1982-02-05
Abstract: A casing type jet perforating gun 28 is located downhole in a cased borehole adjacent to a hydrocarbon containing formation 16. A gun firing head 30 is connected to the uphole end of the casing gun. A capillary tubing 36 is wound on a large reel 44, and the lower end of the tubing is connected to support an apparatus 40 for actuating the gun firing head. The gun firing head, when actuated, detonates the shaped charges and perforates the casing. The upper end of the capillary tubing 36 is connected to a supply of fluids which flows at a measured pressure and flow rate. The lower end of the tubing 36 is open so that flow can occur from the fluid supply, through the entire length of the capillary tubing, and out of the lower open end of the tubing. The gun firing device 40 is lowered down through the tubing 18 of the borehole by rotating the reel 44 until the device is positioned in close proximity to the gun firing head 30. The downhole pressure is measured from the surface. The capillary tubing is next used to manipulate the gun firing device so that it contacts the gun firing head causing the charges of the gun to be detonated to thereby perforate the casing and complete the well. A surface recorder 48 monitors the downhole conditions during the completion of the well. The apparatus is left downhole until the well has been cleaned up and thereafter shut- in to enable the shut-in pressure at the formation to be measured. <IMAGE>

Title: Lift valve sealing arrangements
IPC: F16K1/34
Filed: 1982-02-08
Abstract: A lift valve has a movable valve member (1), a stationary metallic valve seat (6), and co-acting sealing surfaces thereon defined by sealing bodies (5, 6) of malleable material, with the sealing surface on the valve member inclined with respect to the motion direction of the valve member. The sealing body (5) on the valve member, which is softer than the valve seat, has the form of a body of revolution generated from a curved line. A permanent deformation of the malleable sealing body of the valve member occurs on closure of the valve which ensures that the valve member and the valve seat preserve their general sealing form despite wear of the sealing surface of the valve member. <IMAGE>

Title: Ironing board cover
Inventor: GANDER WOOLF
IPC: D06F83/00
Filed: 1982-03-09
Abstract: Laminated ironing board covers are known to comprise a woven heat resistant outer layer and a foamed inner layer. The present invention provides an arrangement whereby the coefficient of elasticity of the foamed layer is adapted to be reduced on application of heat and pressure, thereby providing means for taking out discontinuities in worn ironing board surfaces. The reduction of elasticity also enables the ready removal of worn ironing board covers so they may be periodically replaced.

Title: Electric heating device
IPC: H05B3/38
Filed: 1981-08-28
Abstract: The present invention provides a flexible continuous sheet heater having a high uniformity in heat propogation that can replace existing thin-wire and etched foil heaters at a fraction of the cost of the existing devices. It is relatively inexpensive to produce, can be used in a wet or damp environment, has a constant watt density per unit length, and is so designed that the watt density can be varied within wide limits. The heater of the present invention includes a paper or plastic substrate (12) on which is printed a semi-conductor pattern (typically a colloidal graphite ink) having (a) a pair of longitudinal stripes (14) extending parallel to and spaced apart from each other and (b) a plurality of identical bars (18) spaced apart from each other and extending between and electrically connected to the stripes. A metallic conductor (22) (typically copper stripping) overlies each of the longitudinal stripes in face-to-face engagement therewith, and the conductors are held in tight engagement with the stripes by plastic sealing layer (23) that overlies the metallic conductors and the semi-conductor pattern, and stripe associated with the particular metallic conductor, to portions of the substrate that are free from the printed semi-conductor pattern.

Title: Code reader
Inventor: ROBINSON ALAN WILLIAM
IPC: G06K7/10
Filed: 1982-07-08
Abstract: A code reader intended primarily for use in a stock control system for a bar selling liquid beverages, includes an optical sensor (2) mounted on an inverted channel member (1) for reading a code pattern of concentric rings printed on a bottle closure (3). The reader is positioned at the point of sale where the closure is to be removed from the bottle, this being carried out by sliding the bottle along the channel member (1) so that firstly the code pattern is scanned by the sensor (2), and then the closure is removed by means of a pivotable claw (4) at the end of the channel member (1). The claw (4) can be locked in a blocking position by a solenoid (11) to prevent closure removal until circuitry coupled to the sensor (2) indicates that the code pattern has been validly read.
