Title: Improvements in or relating to inflatable body-attachments for marine lifesaving
Inventor: SMITH REX STANLEY
IPC: B63C9/125
Filed: 1959-02-17
Abstract: 870,877. Inflatable life-jackets. FRANKENSTEIN & SONS (MANCHESTER) Ltd., P. Feb. 11, 1960 [Feb. 17, 1959], No. 5424/59. Class 77. An inflatable marine life-saving appliance, Figs. 2 and 3, having a neck opening 13 and adapted to be attached to the wearer's chest by means of a waist-encircling tape or tapes 29, is characterized in that the tape or tapes is or are normally anchored to, but capable when tensioned of sliding along, a loop of flexible material 32 whose ends are secured to patches 33 cemented to the opposite faces 10 and 11 of the appliance, at the lower part thereof. As shown in Fig. 4, the single length tape 29 has its central portion gathered into a small bight 30 by means of an attached strip 31 the resultant eye encircling the loop 32. When the appliance is deflated a press fastener element 34, within the eye of the tape, is connected to the other element 35 of the fastener, secured to the mid point of the loop. The loop 32 straightens out when the appliance is inflated but as soon as any pull is transmitted to the tape 29 by the press fastener 34, 35 the latter at once gives way and the loop 32 thereafter draws freely through the eye 30, 31 of the tape 29 which thus acquires no appreciable extra tension due to the expansion of the appliance. Thus if the appliance is worn back to front the tape will still position the lower end of the appliance without tightening the tape. The appliance is inflated from a gas bottle 17 operable by a toggle 19 and has oral inflation tubes 21, 22, and a lamp 25 connected by a cable 26 to a water-activated battery 27, The main buoyancy chamber 15 is divided into two compartments by a diaphragm 16. In another embodiment the appliance has a key-hole shaped neck opening and lifting beckets on either side thereof. The gas bottle is carried within the chamber 15 and operable by a pull knob disposed at the bottom of the appliance. A single long oral inflation tube is provided medially of the panel which normally faces outwardly of the wearer, so that if the appliance is worn back to front the tube can extend through the neck opening. The invention can also be applied to a "split-stole" jacket having permanentlyconnected front lobes and provided with a waist-attachment tape or tapes. Specification 673,035 is referred to.

Title: Method of and system for controlling air to fuel ratio for an internal combustion engine
IPC: F01N3/38
Filed: 1973-02-06
Abstract: 1453312 Regulating IC engine fuel injection; spray carburetters GKN TRANSMISSIONS Ltd 30 Jan 1974 [31 Jan 1973 6 Feb 1973] 1988/74 and 5760/73 Divided out of 1453311 Headings F1B and F1H In a fuel injection apparatus or carburetter heat is derived from the burning of a sample of exhaust gas and sensed to provide a signal for controlling the air/fuel ratio. In a fuel injection apparatus as described in 4764/73 the sample is withdrawn from the exhaust pipe 34a and sampling pipe 37a by maintaining a lower pressure in a combustion chamber 37 by virtue of a connection 38 to the inlet manifold 16. The sample is mixed with air from an inlet 39 and ignited by a glow plug 40. A temperature responsive element 57 responds to the change in temperature and operates the control means 29.  The combustion chamber may be located remote from the apparatus Fig. 3 (not shown). The resistances of the glow elements (141a, 141b) change as a function of their temperature, one element being shielded from the combustion. A comparator (170) compares the resistances of the glow elements and an amplifier applies the amplified difference to a heating winding (172) in a heat relationship with a thermostat (157) thereby controlling the air/fuel ratio. The invention as applied to a carburetter includes a thermostat 220, Fig. 5, and a heating winding 221 which cause axial movement of an orifice surrounding a needle 218 according to the heat produced on combustion of the exhaust gas sample.

Title: Method of extracting from solids by means of liquids
IPC: B01D11/02
Filed: 1958-02-24
Abstract: 827,494. Extracting solids with liquids. REYMERSHOLMS GAMLA INDUSTRI A.B. Feb. 24, 1958 [March 1, 1957], No. 5883/58. Class 81 (1). [Also in Group II] Soluble constituents are extracted from finely divided solids by placing the solid in a vessel containing a solvent of low dissolving power which is then passed upwards through the vessel and replaced by solvents of increasing dissolving power as the leaching progresses, solid being added to the vessel during leaching and the supply of solvent being so controlled that the solution leaving the top of the vessel remains at a constant strength. As described, the process is applied to the leaching of roasted clay with sulphuric acid to recover the alumina content as aluminium sulphate and is preferably worked using a series of identical tanks. Each tank has a capacity of about 50 cubic metres and six are employed in the example quoted, two, E and D, being shown the other four being arranged in pairs F, A and B, C behind tanks E and D respectively, the top of one tank being connected to the bottom of the preceding tank. The leaching is preferably carried out at elevated temperature (e.g. 95 C.) and at the start of a cycle of operations, two adjacent tanks, A and F for example, are empty, the tanks E, D, C and B containing the solid in increasing order of content of soluble constituents and 30-50% aqueous sulphuric acid is pumped by pump 28 from inlet pipe 12 upwards through the roasted clay supported on a perforated shelf 2 and overflows into receiver 22 via the valve 20 and thence into the inlet 12<SP>1</SP> of vessel D. This procedure is repeated in each of the tanks D, C and B and when 15 cubic metres of solution almost free from sulphuric acid have passed into tank A, 15 tons of granulated roasted clay are added by a shake-board 4, hopper 3 and feed pipes 5. The pumping of solution continues and a solution practically free from sulphuric acid passes from the overflow 16 of tank A to receiver 21 and pipe 24 to be treated for recovery of aluminium sulphate. Each time the content of free acid in the solution passing from tank A tends to increase, 5 ton portions of clay are added until tank A contains 45 tons of clay after which solution containing free acid is pumped to tank F which serves in place of tank A in the next cycle. The leached material in tank E is washed with water, the washings being used to make up the acid solution, and the solid is removed from the tank through the openings 31 on to conveyer belts 34 and 35 and the liquid is drawn off from outlet 15. The process is then repeated with the tank positions interchanged, i.e. D is operated as E, C as D, &c. Fumes generated during the extraction are removed through hoods 6, pipes 7 and extractor fans 9.

Abstract: 1491524 Programme interruption COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE CII HONEYWELL BULL 12 Feb 1975 [13 Feb 1974] 6007/75 Heading G4A When the execution of a programme stored in an area P of a main memory 10 of a dataprocessing unit is interrupted, the contents of registers used by the programme and data stored in the main memory 10 are transferred to a reserved area of a memory, the data transferred to the reserved area being able to be examined and/or altered if necessary by an operator by means of a control unit 30, the data in the reserved area then being retransferred to main memory 10, with all of these steps being controlled by microprogrammes. In the illustrated embodiment, these microprogrammes are stored in an area p of the main memory 10, and the reserved area is located in an auxiliary memory 20, but the microprogrammes may alternatively be stored in an auxiliary memory, and the reserved area may be located in the main memory 10. The control unit 30 incorporates a maintenance panel on which the address of a desired data item may be set, this address being checked in a comparator 31 to determine whether it is less than the maximum address limits of main memory 10 and auxiliary memory 20; if this is so the value of the data item read from memory (10 or 20) or the value of the data item written into memory is displayed on the maintenance panel. The interrupted or "stopped" state is initiated at the end of execution of a programme instruction when a "stop" order is present at the control unit 30. A rotary switch on the maintenance panel determines which one of three modes of initiation of the "stopped" state shall be employed, each resulting in the generation of a "stop" order at the control unit 30: (1) initiation by actuation of a "stop" button on the maintenance panel; (2) initiation following the execution of each instruction, or (3) initiation following the execution of an instruction whose address is set on the maintenance panel. A further rotary switch on the maintenance panel determines the operation to be performed on the selected data item, viz. read or write from or into the main memory 10 or a register. Following any desired examination or alteration of the data item, actuation of a "resume" button on the maintenance panel causes retransfer of the data to their initial addresses in main memory 10 or in the registers, the programme resuming execution at a point determined by the stored value of an instruction counter. Should resumption of the programme be attempted in mode (3) of initiation of the "stopped" state, i.e. with an address set on the maintenance panel, this is prevented unless the set address is valid, i.e. unless it is less than the maximum address limits of the memories.

Abstract: 546,225. Rubber-covered retractile cord; electric cables. STANDARD TELEPHONES & CABLES, Ltd. May 9, 1941, No. 6022. Convention date, June 5, 1940. [Class 70] [Also in Group XXXVI] A rubber-covered rectractile cord is made by applying a vulcanizable composition to a conductor and partially vulcanizing it continuously in extended form, winding the cord thus made into helical form and completing the vulcanization so as to set the cord in the wound form. The first stage of vulcanization may be effected, in an elongated tube through which the cord travels immediately after being formed at the extrusion head, by steam at 60 lbs. per square inch and is to such an extent that the rubber is not readily distorted, and adjacent convolutions do not adhere together, when the cord is wound on a mandrel 29 on which it is held by clips 31. The vulcanization is completed e.g. at 60 lbs. per square inch for 10 minutes in a chamber which may contain a number of wound lengths. The retractibility may be enhanced by leaving spaces between adjacent convolutions and inverting the cord by drawing one end through the helix after final vulcanization.
