Filed: 1927-06-17
Abstract: 300,974. Brecknell, Munro, & Rogers, Ltd., and Dolman, H. J. June 17. 1927. Delivery of articles stored in piles. -The bottom article of a pile 3, Fig. 5, in a magazine 4 is delivered by a push-bar 10 carried by a plunger 8 which is provided with an operating knob 9. The plunger, normally locked in its inner position, is, after it is freed by prepayment, first pulled out to allow the bottom article to drop to a shelf 5. and then pushed in to push the article to a delivery shoot 27 extending beneath the magazine. The plunger 8 may be connected by side plates 35 with an end plate 36, so that, when the plunger is pulled out, the plate 36 covers the gap at the back of the magazine and prevents fraudulent abstraction of articles through the shoot 27. The plate 36 has a sloping portion 37 which forms part of the shoot 27. Coin action, with stationary coin forming abutments.-A coin inserted through a shoot 19, Fig. 2, moves aside a weighted pawl 31 and rests on a shoulder 33 formed on the arm 18 of a bellcrank 17, 18. The pawl 31 returning prevents the coin from being moved upwards. The lever 17, 18 is pivoted on a pin 14 extending laterally from a side plate 13 carried by the bar 10, and the nose 21 of the arm 17 engages a rack 22 to lock the plunger 8 in its inner position. When the plunger is pulled out, the arm 18 strikes the coin and the lever 17, 18 is turned against the action of a spring 25 until a lateral pin 23 engages an upper rack 24, which ensures a full outward stroke of the plunger.

Title: Power unit
IPC: F02D41/00
Filed: 1976-04-21
Abstract: 1528069 Controlling supercharged IC engine power-plant FRANCE ARMED FORCESMINISTER OF 21 April 1976 [24 April 1975] 16210/76 Heading F1B In a power-plant comprising a diesel engine 10 with a turbocharger 11, 12 and an engine by-pass conduit 22, a throttle 25 is provided downstream of the junction of the by-pass 22 and engine intake pipe. Control means operate the throttle 25 to automatically limit the air-flow rate to engine 10 when the plant is delivering a fraction of its maximum rated power. The plant is started by turning the turbocharger 11, 12 (by motor 15) and supplying fuel to an auxiliary combustion chamber 19 whilst biasing springs 41, 44 maintain the throttle 25 closed and hot gases pass along duct 26 and into engine inlet manifold 18 and out through valve 54 see Fig. 4, to warm the inlet manifold 18. The engine 10 is cranked so that an oil pump 28 pressurizes line 30 to close valve 54 and seal the manifold. The oil pump 28 supplies oil at a pressure proportional to the square of engine speed, to move piston 43 gradually leftwards opening the throttle 25 yet ensuring that sufficient air-flow is maintained in duct 22 to supply the auxiliary combustion chamber 19. The ratio of throttle opening rate/engine speed is modified in accordance with ambient temperature by bleeding oil through a constant throttle 33 and a variable throttle 35, to counter-pressure chamber 42, the variable throttle 35 being regulated by a capsule 37. When supercharger pressure reaches a level determined by a spring 47 acting against piston 46, a slide valve 45 is closed shutting the bleed 33 to move piston 43 to its extreme left position thus over-riding the engine speed dependant control of the throttle 25. This pressure level can be varied with temperature by providing an ambient temperature dependant throttle assembly 49, 50 in the line (chain-dotted) connecting piston 46 to the intake pipe 18.

Title: Haemoglobin preparation
IPC: A61K38/16
Filed: 1977-04-22
Abstract: Human erythrocytes are washed several times with alkaline wash solution, then haemolysed and treated with a cation exchanger in the H<+> form up to pH 5.0 - 5.5, then freed from resin and precipitated stroma material by cold centrifugation and diluted with water. Adjustment to pH 7 - 9 is then carried out using sodium hydroxide solution. The electrolytes are made up to a concentration analogous to blood plasma by additions of salt. After addition of glucose monohydrate, stirring is carried out in vacuo and the oxygen is displaced by nitrogen. The solution obtained is treated with pyridoxal-5-phosphate, with further stirring under nitrogen, then it is rendered weakly alkaline with dilute sodium hydroxide solution and finally sterile filtered. By means of the additional process steps of treatment of the preparation, before making up to the electrolyte concentration of blood plasma and before the addition of glucose monohydrate, with sodium borohydride and then with a dialdehyde and salting out or separation of uncrosslinked haemoglobin by ultrafiltration, the residence time of the preparation in the bloodstream can be increased to 4 - 9 h. The preparation obtained is suitable for intravenous injection and does not cause any pyrogenic reaction.

Abstract: 958,459. Thermal switches; control circuits for heating apparatus. KING-SEELEY THERMOS CO. May 3, 1962 [Jan. 3, 1962], No. 16971/62. Headings H2B and H2H. [Also in Division F4] The supply circuit for an electrically heated oven (see Division F4) includes an on-off switch 26, a switch 27 for selecting either the baking element 16 or the broiling element 17, and a thermally operable switch 28. Rapid preheating prior to baking may be produced by manual closure of switch 51, which is retained closed thereafter by solenoid 52, and which connects the two elements in parallel. Solenoid 52 is de-energized when thermostat switch 28 opens for the first time, allowing switch 51 to revert to its normally open position, in which it remains independent of subsequent making and breaking of the switch 28. Switch 28 includes one contact 33, the fixed position of which is adjustable by rotation of cam 42, and a contact 32 which is displaceable by bimetal 30 and is in series with a resistor 31 mechanically secured to, but electrically insulated from, the bimetal 30. The switch is operated by the combined effect of the ambient temperature, which is related to the oven temperature, and of heat from resistor 31, which latter elongates with rise of temperature to increase the contact pressure until the contacts part, whereafter its subsequent contraction increases the contact clearance.

Title: Improvements in or relating to methods of making barriers in semiconductors
IPC: C30B15/00
Filed: 1953-06-19
Abstract: 744,929. Semi-conductor devices. SYLVANIA ELECTRIC PRODUCTS, Inc. Juno 19,1953 [June 19, 1952], No. 16999/53. Class 37. An electrical translating device comprises a PN junction produced by bringing a semiconductor body of one conductivity type, into contact with a heated mixture containing the semi-conductor to saturation point and an impurity of the opposite conductivity type, the mixture having a melting point below that of the solid semi-conductor. In Fig. 2, pure germanium is added to pure antimony liquid 12 until the molten mixture is saturated, and a small additional quantity of germanium 14 is added to ensure the melt remains saturated with germanium. The respective proportions of antimony and germanium may then be controlled by controlling the temperature of the melt. A slab of P-type germanium 10 is introduced into the melt, so that the donor impurity antimony diffuses into the solid germanium to convert part of it to N-type. The extent of diffusion can be accurately controlled by varying the time and temperature. In an alternative process, the melt is cooled during the treatment so that N-type germanium material heavily doped with antimony forms on the surface of the P-type germanium body. Fig. 3 shows the germanium body after diffusion treatment having P and N portions of material. The body may then be used as a rectifier, or if the ends and edges are cut away, as a junction transistor having collector and emitter electrodes 16 and 20, and base electrode 18. Silicon may be used instead of germanium. Aluminium, gallium and indium are specified as suitable acceptor impurities, and phosphorus, arsenic and nitrogen as donors. Tin may be used in conjunction with a small amount of boron or other donor or acceptor impurity, to decrease the melting point of the mixture without involving excess concentrations of impurity in the resulting material. The mixture may be applied to the surface of the semi-conductor as a pellet, alloy or as powders and then heated. Photo-electric effects are referred to.
