Abstract: 585,925. Letter-cards. POWER, R. F. March 9, 1944, No. 4424. [Class 146 (ii)] A letter-card comprises a sheet with a tear-off marginal strip B along one edge or two parallel edges separated from the main body of the sheet by an interrupted weakened or perforated line C and so arranged that when the sheet is folded for transmission by post it is secured by sealing the overlapping parts of the strip by adhesive, the interruptions C<1>, C' in the weakened line being so located as to extend beyond each side of the fold lines about which the sheet is folded. In one form, Fig. 1, the strip B is formed at one end of the sheet A by a line of perforations C. Adhesive is applied at D' and D<2>, and the sheet is first folded along a line E<1> so that the lower edge a coincides with the line C. Transverse folds E', E' are then made, the part D<2> stuck down on to the part D<3> and the part D<1> stuck down on to the back of the part D<2>. The part A' may be tucked into the part A<1>. Further, adhesive may be applied to the part D' instead of to the part D<1> or D<2>. A printed mark F may be provided to indicate where the edge a<1> lies after folding along the line E<2>. In a second form, Fig. 3, detachable strips B are provided along two parallel margins, and adhesive preferably applied only at D' and D<2> or alternatively at D<1> and D', although it may extend over the entire length of the strips B. The sheet is folded along the lines E, E' and the margins stuck together. A folding mark F is provided as before, and instructions may be provided on the margins. The gumming as well as the perforations may stop short of the folding lines E, E<1>. The gumming may be omitted and the sheet sealed by strips of adhesive paper. The strips B may be coated with latex so as to be self-adhesive, in which case, a portion of part D' is cut away so that when fold E is made, a part of D<2> is exposed for adhesion to the part D'.

Title: An improved device for dispensing plastic or semi-liquid material in predetermined quantities
IPC: G01F11/02
Filed: 1942-04-03
Abstract: 555,075. Delivering measured quantities of semiliquid materials. SPRATT, H. HART-. April 3, 1942, No. 4472. [Class 106 (v)] The downward movement of a rod 18 projecting through the top of a cylindrical container 1 applies pressure through a spring pressed clutch member 25 to a piston 22-resting on the top of plastic or semiliquid material in the container and operates a valve 9 against the resistance of a spring 13 to close against a floating sleeve 8 mounted between the valve 9 and a perforated disc 12 on the valve stem so as to slide in a tubular member 6 at the bottom of the container 1. The continued movement of the rod 18 until it engages with a cap 11 on the member 6 moves the sleeve 8 downwards to uncover openings 7 in the member 6 through which the plastic material passes to the space above the valve 9. When the rod 18 is released the valve 9 is moved upwardly by the spring 13 and the sleeve 8 is raised by the disc 12 to close the openings 7, the material above it passing to the lower part of the tubular member 6. The rod 18 is also raised until a collar 21 abuts against an adjustable guide 19 at the top of the container 1. The measured material is extended through a nozzle aperture 4a in the container on the next operation of the rod 18. The clutch member 25 consists of an internally tapered ring which is supported by a cap 26 above a spring 27 and contains balls 28 pressed downwardly by a spring 30 against the ring and rod 18. The. spring 30 abuts against a clutch housing 2 the upward movement of which is limited by a cap 24 on the piston boss 23 so as to release any pressure on the material on the completion of the upward movement of the rod 18. A disc 33 on a sleeve 32 surrounding the rod 18 allows the balls 28 to be moved out of the gripping position when the piston is to be adjusted on the rod 18.

Abstract: 567,650. Electric discharge devices. CINEMA-TELEVISION, Ltd., and SOMMER, A. March 19, 1943, No. 4507. [Class 39 (i)] [Also in Group II] Alloys for manufacture into layers which are transparent and of good electrical conductivity consist of gold and caesium or other alkali metal, the amounts of the two metals being in accordance with the formula AuX, where X represents the alkali metal. The alloy may be deposited upon a transparent support for use in the evacuated bulbs of electron discharge devices, such as television transmitting tubes, cathode-ray tubes, or as the electron-emitting layer of a photo-electric cell. The transparent layer may be made by evaporating, in an enclosed vessel, the alkali metal on to a layer of gold white maintaining the latter at a raised temperature, e.g. 150-250‹ C., and removing any alkali metal in excess of that required to alloy with the gold in the stated proportion by evacuating the vessel while maintaining the raised temperature. The gold layer is deposited by evaporation, sputtering, or deposition from solution.

Title: Treatment of polymeric fat acids
IPC: C07C51/487
Filed: 1965-02-03
Abstract: Polymeric fat acid products containing iron and/or phosphorus as impurities are treated with a 40 to 80% by weight aqueous solution of phosphoric acid to reduce the iron and/or phosphorus content of said products.  The quantity of phosphoric acid employed is generally 1 to 3% by weight of the product to be treated and said treatment is then generally conducted immediately following the polymerization reaction in the polymerization reaction vessel at 250 DEG  to 300 DEG  F. for 1/2 to 3 hours. The treatment is of particular value when the polymeric fat acids have been prepared in the presence of clays and lithium compounds.
