Abstract: 1345429 Micro-biological testing COMPAGNIE GENERALE D'AUTOMATISME 11 Aug 1971 [11 Aug 1970] 37697/71 Heading C6F Aerobic and anaerobic investigations of a bacterial culture are conducted in a plastics receptacle of circular or elongated configuration consisting essentially of a first plate 10, Figs, 1 to 3, provided with cells 11 and a second plate 20 carrying annular platelets 22 of an absorbent  material (specified) impregnated with substrate or colouring agent. The second plate and platelets have corresponding apertures 21. In use the plate 20 is placed over plate 10 as shown and with the aid of a series of punches, the platelets and associated plastics material of the plate 20 are cut out. A suspension of bacteria is injected into each of the cells 11. The apertured platelets float on the surface of the bacterial suspension thereby affording both aerobic and anaerobic conditions of growth. When using the device depicted in Fig. 2, the cells 23 of the plate 20 may be floated on the suspension so that punching out is rendered unnecessary. The device may include a third plastics plate 30, Fig. 3.

Convention date, Dec. 8, 1928. [Class 34 (i).] In an air-heated apparatus for lacquering and drying &c. several heating chambers through which the wire &c. is passed are arranged around an air-heating oven. Preferably the air from the heating chambers is passed through a preheater in which it warms the fresh air. The heating chambers may be vacuum jacketed, and the inner surfaces thereof polished to form reflectors. The heating chambers c, Fig. 2, are arranged around the oven a to which fresh air is supplied by a fan through the pipe b. The heated air from the oven a passes into the chambers c through pipes d, and passes out of the chambers through pipes f which pass through a preheater e in close contact with the air supply pipe b. The air may circulate in a closed circuit. The chambers c are constructed with an inner chamber h, Fig. 3, through which the wire is passed in known manner, surrounded by a tube i, the inner face of which is provided with a reflecting surface. A vacuum is maintained between the tube i and the outer tube k. The wire, after passing through a bath of lacquer, is passed several times through a chamber c, and then passes round a pulley o, Fig. 2, and thence to a reel. All the pulleys o are driven by rollers n in contact with a disc m, forming a variable speed mechanism.

Heading H1D A cathode-ray tube as described in the parent Specification wherein a plurality of dynodes in the form of glass plates with aligned apertures are sandwiched between an extended area cathode and a target electrode to define a number of electron paths which can be controlled by potentials applied to electrodes on the faces of the dynodes, is characterized in that each dynode carries on one face a single electrode at a fixed potential and on the other face a pair of interdigitated electrodes which can be selectively connected alternatively to a blanking or to a forward bias potential. The single electrode of each dynode may be connected to an appropriate tap on a potential divider extending from cathode to anode; each interdigitated electrode of a dynode may be connectible by a switch (transistor) to either one of a pair of oppositely poled batteries, the other terminal of which is connected to the same potential as the single electrode. With the interdigitated electrodes oppositely biased on each dynode, a single electron path is opened, as in parent Specification, if all the interdigitated electrodes are forward biased, all the electron paths are opened to give the effect of a flooding beam which could provide an " erase-read " operation, and intermediate conditions may also be utilized to provide selective flooding.

Abstract: 1,072,480. Filler valves for gas lighters. S. KITABAYASHI. Sept. 23, 1964 [Sept. 26, 1963], No. 38786/64. Heading F4F. A filler valve for a liquefied gas lighter comprises a porous elastic sponge 3 normally urged by the flange 7 of a spring - loaded plunger 2 against an annular portion 8 of a member 1 which is fixable to a wall (not shown) of the lighter fuel reservoir, so that as the plunger 2 is moved downwards (as shown) by a fuel supply container 6, the flange 7 disengages from the sponge 3 which expands and allows the exhaust therethrough of residual gas but not of liquefied gas from the reservoir to the atmosphere, when the pressure in the fuel reservoir becomes excessive. The plunger 2 has an axial passage 4 and a transverse passage 12 through which liquefied gas from the supply container 6 is discharged into the lighter reservoir. In the closed position of the valve, the compressed sponge 3 seals off the residual gas passage, and the liquefied gas passage 12 is above the sponge 3. In another embodiment, Figs. 3, 4 (not shown), as the plunger 2 is depressed by a limited amount, the sponge 3 is initially decompressed but then a tapered section of the shaft of the plunger 2 compresses the sponge 3 so that the porosity of the sponge is decreased. The sponge 3 passes residual gas when a certain pressure is reached in the reservoir.

[Also in Group XXIV] A compressor drive-shaft arrangement for a gas turbine power plant comprises at least three bearings and two shaft portions, for the turbine and compressor rotors, respectively, which are centred one through the other and are coupled together as regards rotation and which, on the final assembly of the shaft, are releasably connected together axially on the compressor side and accessibly from the outside. A hollow compressor shaft portion V 2  receives an extension T 2 <SP>1</SP> of a turbine shaft portion T 2 , which extension is provided with an internal thread into which is screwed a bolt 25 by means of a long box spanner. The bolt has a collar 25<SP>1</SP> which tightens a disc 26 against a step 23 in the hollow shaft portion and the end face of the extension to provide an axial abutment. A locking sleeve 27, is pressed against the collar 25<SP>1</SP> by a short bolt or plug 28 screwed into an internal thread in the end of the compressor shaft portion. The turbine and compressor shaft portions are splined together at 20<SP>1</SP> and are centred at 21. During operation, a thrust exerted on the shaft portion T 2  in the direction of arrow Y is transmitted by way of abutment 23, 26 to the shaft portion V 2  which is subjected to a larger thrust in the direction of arrow X. The thrust difference is taken by a bearing 11. In an alternative embodiment, the extension projects right through the hollow shaft portion. An externally threaded portion on the end of the extension protrudes from the hollow shaft portion and is provided with a nut which tightens a flanged sleeve against a shoulder on the extension and the end face of the hollow shaft portion, to provide the abutment. The extension is provided with an intermediate expansible portion of reduced area.

The hammer 50 is biased toward a cam 51 by means of a spring-46 and in its operative position as shown, the hammer actuates the cam to reset a seconds hand. When the user depresses a button (not shown), and thus displaces the member 33 against the force of a spring 34 to index the wheel 40, the projection 43 is forced out of a recess 42<SP>1</SP> and the hammer 50 becomes spaced from the cam 51. A further depression of the button restores the mechanism to the position shown.
