Patent GB-297324-A (GB)
Abstract: 297,324. Muller, J. Sept. 15, 1927, [Convention date]. Piston apparatus for discharging receptacles.- The supply of lubricant under pressure to and the delivery from a piston pump are controlled by a rotary independently-operated multiple-way valve 47, and a shaft connected through rack-and-pinion gearing with the pump piston carries a handle for indicating the position of the piston and is adapted to be locked, so as to arrest the piston in any position when desired, by means such as a pawl adapted to engage a pinion on the shaft or a cam adapted to be jammed against a wheel on the shaft. As shown in Fig. 1, the discharge stroke of the piston 6 is effected by a spring. In the position shown, the supply pipe 46 is in communication with a pipe 45 leading to the cylinder 3 through a passage 51 in the valve, the delivery pipe 26 being cut off from the cylinder. By turning the valve through 90‹, the pipe 46 is cut off and the pipe 26 is put into communication with the pipe 45 through a passage 50 in the valve and a passage 52 in the valve casing. As shown in Figs. 2, 3, wherein the cylinder contains a double piston, the valve 47 is so arranged that the movement of the piston produced by the charging of either end of the 'cylinder causes delivery from the other end. In the position shown, the end 3 of the cylinder is in communication with the supply pipe 46 through a right-angled passage 51 in the valve and a pipe 45, while the end 3<1> is in communication with the delivery pipe 26 through a pipe 45<1> and a right-angled passage 50 in the valve. By turning the valve through 90‹, the end 3<1> is charged through passage 51, an axial passage 54 in valve casing, and pipe 45', while end 3 is being discharged through pipe 45, an arcuate passage 53 in valve casing, and passage 50. The Specification as open to inspection under Sect. 91 (3) (a) referred to Specification 279,083, [Class 102 (i), Pumps &c.], but this reference does not appear in the Specification as accepted.

Filed: 1924-12-11
Abstract: 238,439. Poole, A. M. M., and Poole, H. C. Dec. 11, 1924. Inductances. - A tuning coil of the kind wound upon a former provided with radial pins j disposed in parallel planes and on which the wire k passes outside one or more pins in one plane across to the other plane, and outside one or more pins of that plane is characterized in that in passing from one outside series to the other the wire passes between a pin on one series and a pin on the other series before it passes outside a pin on the outside series. The pins in the series, of which there may be two or three, need not be opposite to one another and may be inclined towards a medial plane.

Title: Improvements in or relating to journal-boxes or bearing sleeves
IPC: B64C11/00
Filed: 1932-10-25
Abstract: 409,299. Bearings. VEREINIGTE KUGELLAGERFABRIKEN AKT. - GES., Schweinfurt, Bavaria, Germany. Oct. 25, 1932, No. 29818. Convention date, Nov. 21, 1931. [Class 12 (i).] In journal bearings of the type having a sleeve 1 which is pressed against a casing 2 by a coil spring 5, an intermediate sleeve 7 surrounds the sleeve 1 and has a slot 10 for engagement with a stop 9 on the sleeve 1 and a stop 8 on the casing. Before inserting the sleeve 1 into the casing the spring is compressed between nuts 6 and the sleeve 7, the upper edge of which engages the stop 9. The sleeves 1, 7, and the spring are then put into the casing and the screw 8 is turned to engage the slot 10 to prevent rotation of the sleeve 7. The sleeve 1 is then turned until the stop 9 engages the slot, when the sleeve 7 rises and the screw 8 engages the bottom of the slot. The Figures show the application to a spinning spindle 15. If the sleeve 7 be slotted as shown in Fig. 8 a fixed stop 8 may be used, the successive positions of which a, b, c, during insertion of the device in the casing are shown by dotted lines. In a further modification, the upper and lower parts of the sleeve are separated and connected by a tension spring inside the sleeve 7, which is elongated to abut on the nuts 6. A form of sleeve 7 which will ensure the automatic passing of the stop 9 into the groove 10 if this be omitted by the mechanic is shown in Fig. 7. Here the top of the sleeve is cut away along an inclined plane passing near the bottom of the slot 10. The vibrations of the machine will cause the stop to move off the small flat 18 on to one of the inclines 17 and into the slot which is of shorter length.

Abstract: 508,468. Coloured stereoscopic pictures. I. G. FARBENINDUSTRIE AKT.-GES. Nov. 1, 1937, No. 29832. Convention date, Oct. 30, 1936. [Classes 97 (i) and 98 (ii)] For the production of stereoscopic colour pictures, use is made of a lenticular film of the kind carrying a multi-layer emulsion for the production of a coloured image, the left and right eye views being recorded separately by the action of the lenticles. According to the invention, the pictures are projected on to a metallic surface by using a polarization filter having two areas which polarize in different directions so arranged in relation to the film that the separate stereoscopic components are projected through different areas, the projected picture being viewed through two polarization filters corresponding to the two areas of projection filter.

Patent GB-829092-A (GB)
Title: Carbonates of octavalent uranium and alkali metals or ammonium
IPC: C01G43/00
Filed: 1945-11-10
Abstract: Water-soluble octavalent uranium alkali carbonate of general formula UO2(AlkCO3)x(OAlk)4-x where "Alk" is alkali metal or ammonium and x is 3 or 4, are prepared by reacting uranium peroxide with an aqueous alkali metal carbonate solution at a pH between 7.6 and 10.8.  The uranium alkali carbonate formed in solution may be reconverted to uranium peroxide by acidifying to a pH between 2 and 5, preferably in the presence of hydrogen peroxide whereby uranium peroxide free from impurity is precipitated.  The uranium peroxide may be treated with the alkali carbonate solution at temperatures from 60 DEG  to 90 DEG C., the amount of carbonate solution preferably being 10 to 20 times the weight of the uranium peroxide.  The alkali carbonate employed is preferably sodium carbonate and from 4 to 5 atoms of sodium per atom of uranium are preferably present.  After reaction with the peroxide the uranium alkali carbonate solution may be separated from the insolubles by filtration and the residue may be washed with fresh carbonate solution which can then be employed for treating the next batch of peroxide.  If uranium peroxide is to be reprecipitated a temperature between 30 DEG  and 65 DEG  C. is preferred. Acidification to a pH between 2.5 and 3.5 may be effected by adding the alkaline solution to a mineral acid preferably sulphuric acid. According to an example, uranium peroxide filter cake contaminated with fluorine was mixed with filtered bicarbonate solution at 60 DEG C., the pH being 8.3.  The resulting solution was filtered from the insoluble residue and the filtrate heated to 40 DEG  to 45 DEG  C., whereupon strong sulphuric acid was added to reduce the pH to 2.  A small quantity of aqueous hydrogen peroxide was added and the pH adjusted to three by the addition of aqueous sodium hydroxide.  The precipitated uranium peroxide was substantially free from fluorine. Specification 829,088 is referred to.

Title: Improvements in or relating to decorative rubber compositions for floors, walls, ceilings or other surfaces
IPC: B44F11/04
Filed: 1931-11-02
Abstract: A method of making coatings or coverings for floors, walls, ceilings or other surfaces consists in adding to rubber latex powdered filling material to form a paste which finally hardens, spreading the paste on the surface to be coated, and pressing into the paste pieces of decorative material.  The decorative material may be one or more of the following materials:-pieces of vulcanized rubber sheeting, hard wood, leather, porcelain or earthenware tiles, and marble slabs.  The latex is preferably stabilized by the addition of a stabilizing agent, for example, cold water glue having a casein base.  There may also be added to the latex vulcanizing ingredients, such as, for example, powdered sulphur, together with accelerators.  To prevent deterioration of the coating an anti-oxidant may be added to the latex.  Suitable fillers for the latex are one or more of the following:-china clay, asbestos, carbon black, barium sulphate, zinc oxide, powdered silica, powdered slate and alumina, or where rapid hardening is desired, filling material of a hygroscopic character such as silica, alumina or an hydraulic cement.
