Title: Device for intergranular exposure of test papers and the like
IPC: G01J1/42
Filed: 1946-04-30
Abstract: <PICT:0611376/III/1> A holder for exposing test papers, or like sheet materials sensitive to relative humidity or to changes in gaseous composition, to the atmosphere between stored cereal grains, comprises a case 1 slotted to receive the holder, one plate 2 of which is larger than the other 3 and the lower part of which fits slidably within the case.  Rod 5 in a tubular stem 4 is provided with a knob 6 and enables the holder to be moved relative to the case. Knob 6 is so positioned that, when in contact with the end of the stem 4, the plates 2 and 3 are in their projected positions, but still contained within the holder 1.  Screwing back the knob 6 against the stop 7 permits further projection of the holder so that the plate 3 is clear of the case and may be removed for the insertion of the test paper between plates 2 and 3. Apertures 2a and 3a in these plates are placed centre to centre with their principal axes at right angles so that the paper enclosed between them is exposed on both sides only in the square over which the apertures overlap. Cover members 11 and 12 lodged and remaining in apertures in the case 1 are pressed inwards by springs 13 and 14 and will lodge also in the apertures 2a and 3a when the paper holder is in the enclosed position, thus sealing the paper from further atmospheric changes on withdrawal.  The edges of either or both the cover members and the holder apertures must be bevelled to enable the holder to move between the covers when it is to be projected.  Cover member 11 is transparent and 12 may be transparent or translucent.  In a modification, the case 1 is provided overall with a thin metal cover or shroud, with an aperture for viewing the test paper through the inner aperture 11.

Title: Improvements relating to electron discharge devices
IPC: H01J19/42
Filed: 1956-04-27
Abstract: 825,217. Thermionic valves. GENERAL ELECTRIC CO. April 27, 1956 [April 29, 955], No. 13000/56. Class 39(1). The electrode system of a discharge tube forms two concentric groups, each group being supported by separate insulators ; the outer group is supported by insulators having a central aperture across which the insulators of the inner group extend, the two sets of insulators being secured together. As shown, the electrode structure is held at each end by a two-part supporting member. One part is a disc 26 of mica or other insulating material, having a central aperture of hexagonal or other shape providing long opposed side edges 30. The other part is a mica strip 34 narrower than the said aperture, so that it may lie across disc 26 with a separating slot on each side. The two parts may be eyeletted together directly or with separating spacers 43, Fig. 4. The high-voltage electrode is supported by tabs passing through slots 31 in disc 26, and the low voltage electrodes are supported from the strip 34. Thus the high and low voltage electrode supports are separated physically and electrically. The high voltage support 26 has a coating of some substance such as sodium or potassium silicate which is slightly conductive at high potentials, so as to prevent the build-up of a charge of arcing magnitufe at any one point. The low potential support 34 has a coating of oxide of aluminium, magnesium, zirconium, or other insulating material, to reduce inter-electrode leakage.

Title: Improved apparatus for dispensing beer and like beverages
IPC: B67D1/14
Filed: 1938-05-07
Abstract: 499,934. Plug cocks. REID, J. May 7, 1938, No. 13645. [Class 135] [Also in Group XVIII] A beverage-dispensing apparatus of the kind in which a selectively-operable dispensing nozzle can dispense the liquid direct from bulk supply, or divert some of the liquid from the bulk supply into a settling vessel, is provided with means permitting the supply of the liquid direct from the bulk supply to the upper part of the settling vessel above the level of the liquid therein while the liquid is being drawn off from the bottom of the vessel. In the apparatus shown, which is a modification of that described in Specification 403,692, a dispensing nozzle 7 combined with a four-way tap 8 is mounted at the end of an arm 6 formed with three passages 9, 10, 11, the settling vessel 5 being mounted at the other end of the arm. The upper passage 9 communicates with a vertical tube 12 extending along the axis of the vessel 5 and in the upper portion of which holes 24 are provided, while the middle passage 10 communicates with the bulk supply by means of a vertical passage in the column 17 by which the apparatus is mounted on the counter, and the lower passage 11 is in communication with an opening 26 at the bottom of the settling vessel. The apparatus operates as follows: (1) On turning the tap 8 through 90‹ in an anticlockwise direction from the closed position shown, the passages 9. and 10 are connected by a recess 27 in the valve plug and the passage 11 is connected with the nozzle 7 by a port 16 in the valve. Liquid passes from the bulk supply, through the passages 10, 9, to the tube 12, from which it passes into the vessel 5 via the holes 24, and at the same time liquid passes through the opening 26 and along the passage 11 to the nozzle 7. The passage 11 is larger than the passages 9, 10, and consequently the vessel 5 will be emptied if liquid is drawn off continuously, but atmospheric air cannot enter the vessel. (2) On turning the tap through 90‹ in a clockwise direction from the position shown, the passages 9, 11 remain closed and the passage 10 communicates with a port 14 in the valve, so that liquid is delivered to the nozzle 7 direct from bulk supply. (3) On turning the tap through 180‹ from the closed position, passages 10 and 11 are connected by a recess 25 in the valve and the passage 9 is put into communication with the nozzle 7 by a port 15, so that liquid passes from bulk supply through the passages 10, 11 to the bottom of the vessel 5, while air and gas pass through the holes 24 in the tube 12 to the nozzle 7. The apparatus may be modified by mounting the settling vessel 5 below the tap level instead of above the tap level as shown.

Title: Improvements in or relating to the treatment of textile material to render the same water-repellent
IPC: D06M11/46
Filed: 1949-05-23
Abstract: 669,772. Waterproofing textile fabrics. STEVENS, A. H. (National Lead Co.). May 23, 1949, No. 13677/49. Class 140. Textile materials are made water-repellent by impregnating the material with an aqueous solution of a zirconium compound of a watersoluble fatty acid and then treating the impregnated material to form a water-insoluble compound. The impregnation may be carried out at a temperature below the decomposition point of the compound and the temperature of the impregnated material then raised above the decomposition point whereby the compound is changed to a water insoluble compound, or the impregnated material may be treated to raise the pH of the solution therein, whereby the compound is changed to a water-insoluble compound. In example (I) a textile material of cotton, artificial silk whose chief ingredient is cellulose or one of its derivatives, wool, or silk is saturated with a 1 per cent solution of the acetic acid co-ordination compound of basic zirconyl acetate (ZrO(OH) (CH 3 COO)CH 3 COOH) at a temperature below 40‹ C. Excess liquid is removed by centrifuging or wringing and then the temperature of the material is raised to 80‹ C. in a steam chest to cause hydrolysis of the zirconium compound. The material may then be dried at 100-105‹ C. or washed in warm water prior to drying. According to example (II) the textile material impregnated as in example (I) is introduced into a dilute solution of borax, or other alkaline salt containing a negative ion which does not form an insoluble compound with zirconium, in order to raise the pH of solution and precipitate the basic zirconyl acetate ZrO(OH) (CH 3 COO) within and upon the surface of the fibres of the material. In other examples the processes of examples (I) and (II) are repeated using a 1 per cent solution of the sodium acetate co-ordination compound of basic zirconyl acetate, and the formic acid co-ordination compound of basic zirconyl formate ZrO(OH) (COOH)HCOOH. A textile material of cellulose, regenerated cellulose, artificial silk whose chief ingredient is cellulose or one of its derivatives, may be treated with a solution of the acetic acid co-ordination compound of basic zirconyl acetate or the formic acid co-ordination compound of basic zirconyl formate at a temperature below 40‹ C. Excess solution is removed and the sample dried slowly to allow the acetic acid portion of the molecule to react with the cellulose.
