Title: Apparatus for controlling gas pressure
Inventor: REDSTONE REUBEN
IPC: H01J17/26
Filed: 1958-01-24
Abstract: 850,950. Discharge apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 15, 1959 [Jan. 24, 1958], No. 2543/58. Class 39(1). In apparatus, for regulating the pressure of hydrogen, deuterium or tritium in a chamber, of the kind including temperature-sensitive storage material, capable of holding the gas, and a heater for increasing the temperature thereof, the storage material consists of a spongy body of sintered nickel iron, silicon or aluminium powder, forming a porous mass of large surface area, impregnated or interspersed with a hydride in powder form of titanium. zirconium, uranium, thorium, vanadium or tantalum. Such replenishers are particularly suitable for ion sources in which a pressure of about 0À005 mm. of Hg or less is required. As shown, the replensiher comprises a fine nickel tube A on to which is sintered a coarse nickel powder forming a porous mass B. A suspension of titanium hydride powder in ethyl alcohol is painted thereon. When the ethyl alcohol has evaporated the hydride adhering to the outside of the nickel is washed off. This unit together with a heater C is supported in a glass envelope E by means of two mica discs D and the pinch wires G. Alternatively, the porous mass B may be formed on the outer end of a hollow cap containing the heater or on the inside of a metal cup or a valve envelope which is externally heated. The replenisher is sealed to the system on which it is required and heated until all the hydrogen is pumped away ; very pure hydrogen is then introduced into the system until the replenisher is fully saturated with hydrogen. The replenisher is kept in this state during all other processes on the system after which it is again fully outgassed and a known quantity of hydrogen is introduced into the system, this quantity being such as to give an atomic ratio of hydrogen to titanium of 0À2 to 1 so that a large excess of free titanium metal is available as a getter. The replenisher may be operated at 0À020 mm. of Hg pressure.

Title: Improvements relating to temperature control of electric stove ovens
IPC: H05B1/02
Filed: 1941-02-25
Abstract: 541,677. Automatic temperature control. HADDAN, R. (Moffats, Ltd.). Feb. 25, 1941, No. 2562. [Class 38 (iv)] [Also in Group XXXVII] In the temperature control of an electric oven, a multi-position switch 32 having, say, four positions "High," "Bake," Grill and "Off" is moved by hand into the " High position thereby turning on the maximum number of heaters for the oven so that this heats up rapidly; when a predetermined temperature is reached a thermal element such as a bi-metallic coil 3 trips the switch 32, which was latched in the " High position, so that the switch 32 returns to the " Bake"  position. Simultaneously with the tripping a main switch 29 of the telling mercury type in series with the switch 32 is moved into its " Off " position thereby cutting off the current to the heaters, and a bell is sounded to indicate that food may be placed in the oven. When the temperature falls below the pre-determined value, the switch 29 will close again and the temperature will thus be maintained by say one heater at the bottom of the oven instead of by two heaters one at the bottom and one at the top. The switch 32 may be moved at any time into the " Grill position in which the heater at the top of the oven replaces the one at the bottom, or passes the " Bake " position a lug, Fig. 5, engages into the " off " position. The switch 32 is operated by rotation of the handle 32 and when it a forked member 36 moving this against a spring 37 till the "High" position is reached and the switch arm 34 is held by a latch 24. The bimetal coil 3 rotates a spindle 4 carrying a cam 8 which engages, at the pre-determined temperature, a roller 20 on a lever 19 which raises a lever 21 carrying the latch 24 and an end portion 25 which tilts the mercury switch 29. The lever 19 is pivoted on an arm 17 which is rotatable about the axis 4 for temperature setting. When the latch 24 is moved the spring 37 moves the member 36 and with it the switch arm 34 and the member 36 also actuates a striker 39 for the bell 38.

Title: Improvements in and relating to the manufacture of threads, filaments, films and thelike from alginates
IPC: D01F9/04
Filed: 1943-02-19
Abstract: Artificial filaments, threads, films and the like are obtained by spinning a solution of sodium alginate into a bath containing a salt of an alkaline earth, a small amount of a cation-active compound and a small amount of an organic acid in the substantial absence of free mineral acid and oil.  The proportion of organic acid may be 0.1-5.0 per cent, e.g. of acetic acid.  It should not be so great that any substantial quantity of alginic acid is present in the free state in the coagulated filaments or other products.  The cation-active compound may be present to the extent of 0.01-0.1 per cent of the coagulating liquid.  In an example, a solution of sodium alginate is extruded into an aqueous solution of calcium chloride containing acetic acid and cetyl pyridinium chloride.  The thread produced is stretched by passing it over two godets and it is collected in a spinning box.  It is formed into skeins, treated with a hot, very dilute solution of calcium chloride, and then dried.  The dry yarn is free from stuck filaments.  In another example, the cation-active substance used is undecyl glyoxaline hydrochloride.  If the liquid used for washing the thread contains traces of alkali-metal or magnesium salts, a small proportion of a cation-active substance should be added to the washing liquid.

Abstract: 541,233. Fluid-pressure servomotors; brakes. CLAYTON DEWANDRE CO., Ltd., TWEMLOW, E., and EDGE, S. H. Feb. 14, 1940, No. 2823. [Class 135] [Also in Group XXXIV] A fluid-pressure servomotor is described in connection with operating a brake for automobiles comprises a reservoir 1 in which oil is contained and which is put into circulation by a pump connected to an inlet pipe 18 and outlet pipe 19. The oil under pressure enters a cylinder 6 and operates a piston 9 or not according as the hollow stem 7 of the piston 9 is closed by a valve 14 or not. This valve is opened by a spring 16 and is closed by a pedal 13, or by hand levers or cranks, and the pressure per unit area on the piston is equal to the pressure per unit area on the valve, so that the pressure exerted on the brake is proportional to the pressure exerted by the pedal, and the brake is operated in part by the mechanical pressure. A spring 11 returns the piston to inoperative position when the pedal is released. The pressure on the piston is limited by a relief valve 22 which returns the oil to the reservoir 1 at a predetermined pressure.

Title: Improvements in delivery mechanisms for printing machines
IPC: B41F21/10
Filed: 1920-02-04
Abstract: 162,786. Barker, R. W., (American Bank Note Co.). Feb. 4, 1920. Delivery apparatus; gripper mechanism.-In a sheet delivery apparatus for rotary intaglio plate printing-machines in which the sheets are stripped from the printing-plate by a set of pivoted grippers on a rotating delivery member, the grippers are so constructed that when opened they yieldingly engage the plate so that each gripper adapts itself to any inequality in the surface of the plate, and means are provided to retard, stop, or reverse momentarily the movement of the delivery member while the sheets are being taken and to accelerate it after the sheet is delivered. As shown, the delivery member comprises a series of discs c with gripping-surfaces c<3> for the gripping-fingers f. Tapes c<1> passing round the discs c co-operate with tapes c<2> to deliver the sheets. The gripper fingers f are loose upon a rock-shaft d operated by a fixed grooved cam d' and have stops f<1> normally held in contact with stops e<2> on members e fixed to the shaft d, by springs g arranged between the fingers f and members e. As the fingers approach the sheet-taking position shown they are opened by the cam d<1>, and owing to the springs g bear resiliently on the printing plate a<1>. Spring metal tongues h secured to the fingers also ensure close contact with the plate a<1> and serve to guide the sheets on to the fingers. The delivery member is retarded, stopped, or reversed momentarily while the sheet is being taken, and to effect this the shaft b of the discs c is driven from the gear i by a pin i<1> on which is a bellcrank j, one arm of which is connected by a link k to an arm b<1> fixed to the shaft b, and the other arm of which has a roller j<1> bearing in a camgroove in a fixed member m. The cam-groove has two concentric parts of different diameters connected by a rise m<1> and fall m<2>. While the roller j' is moving in the concentric parts the speed of the shaft b is the same as that of the pin i', but as the roller j<1> moves along the rise m<1>, which occurs when the grippers f are opened to take a sheet, the link k receives a backward thrust to retard stop or reverse the movement of the shaft b. When the roller j<1> moves down the fall m<2>, the shaft is correspondingly accelerated, and this occurs after the delivery of the sheet to the tapes c<1>, c<2>.
