Abstract: 1,101,033. Moulding lipsticks and the like. KOLMAR COSMETICS (EUROPA) A.G. 19 March, 1965 [27 March, 1964], No. 11762/65. Heading B5A. In a method of moulding material that shrinks on setting e.g. lipstick, in which the molten material is cast into an open mould and cooled, the free surface layer of the material is kept in the fluid state by local radiation heating during at least part of the mould cooling time. This prevents shrinkage holes in the moulded article. The heating may be carried out towards the end of the solidification process and the mould may form a packing case for the article. Moulds (10) containing molten material are carried on a conveyer belt (40) through a cooling zone A where the material cools to room temperature, then below a heating ramp (42) consisting of infra-red radiation to locally heat the surface of the material and then through a final cooling zone (44).

Title: Improvements relating to rectifying detectors for high frequency alternating electric currents
IPC: H01L21/00
Filed: 1942-08-26
Abstract: 579,322. Crystal detectors. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., THOMPSON, L. E., and JENKINS, A. Aug. 26, 1942, No. 12019. [Class 40 (v)] [Also in Group III] A crystal detector element is formed of lead sulphide which is precipitated in a crystalline condition and subsequently ground, the resulting powder being compressed and used in.conjunction with a cat's whisker or counter electrode. The precipitate is formed by adding an excess of a solution of sodium sulphide to a solution of lead acetate. After washing, the precipitate is mixed to a paste with a little sodium sulphide solution and heated to 600- 700‹ C. The cooled residue after grinding and mixing with flowers of sulphur is heated to 900-1000‹ C. to burn off the sulphur. The resulting powder is then pressed into a pellet by means of a weighted plunger and the pellet, after heating in a bunsen flame and cooling, is burnished with thallium metal. The new surface is then burnished with paper and annealed at a temperature not exceeding red heat. The characteristics may be improved by the addition of a suitable chloride to the lead acetate solution before precipitation and small quantities of iron salts and thallium salts may be added at various stages in the process. For use as a detector, the pellet is mounted in a conducting bush screwed into an outer casing which holds the cat's whisker in the form of a spring steel wire, the casing being filled with a mineral jelly. The element may be passed on to a roughened metal base, or it may have an electrode surface of metal or colloidal graphite applied as by cathode sputtering, plating or spraying.

Abstract: 1,208,729. Stamping; working at specified temperatures; making dies. PRESSED STEEL FISHER Ltd. 18 Dec., 1967 [23 Dec., 1966; 8 March, 1967; 15 March, 1967], Nos. 57753/66, 10802/67 and 12067/67. Headings B3A, B3Q and B3V. A method of forming a superplastic alloy plate or sheet 44 in a die 19 comprises subjecting one face of the sheet to a liquid 43 that has been heated to within, or above, that range of temperatures at which the alloy becomes superplastic until the sheet has been heated to within this range, and then applying sufficient pressure to the liquid to so sorce the sheet towards the die that the sheet is formed at a strain rate below the critical rate while subjecting the heated liquid and hence the sheet or plate to highfrequency vibrations. Examples of alloys which are superplastic below a certain critical strain rate are the eutectoid alloy of aluminiun and zinc, and the eutectic alloy of silicon and aluminium. The heating liquid 43 may be a molten low-melting-point alloy, an acid or a salt. The sheet may be pre-stretched in a separate operation by vacuum or press forming, or it may be pre-stretched after heating within the superplastic range by pressure applied to the hot liquid with the die 19 retracted, or the sheet may be stretched by a male die. Apparatus for performing the method includes a concrete die 19 with embedded electric heating coils 22, controlled by a thermocouple responsive to temperatures adjacent the forming surface 20, and compressed-air passages for cooling and ejecting the formed sheet, as described in Specification 1,208,730. The die is operated by a pneumatic cylinder 15. A concrete block 24 supports a steel chamber 25 connected by a conduit 31 to a reservoir 32 for the liquid 43. The top of the reservoir is connected, through a regulating valve 37, to a supply 39 of compressed-air and also to a metering valve 40, a metering pump 41 and a pressure release valve 42. Heating coils 26, 33 and 35 are provided controlled by thermocouples 27, 34. A high-frequency signal generator 28 for subjecting the sheet to vibrations above 10 kc./sec. and producing an air bearing between the sheet and die has a horn 29 projecting into the chamber 25. Working at specified temperatures.-The molten alloy and the die-surface 20 are maintained at 260‹ C., the sheet being loosely held between the die and base 24 until contacted by the liquid and raised to 260‹ C. The die is then firmly clamped, the generator 28 energized and highpressure air supplied to the reservoir 32 for effecting the forming operation.

Title: Improvements in the manufacture and production of lubricating oils
IPC: C10M107/00
Filed: 1938-04-25
Abstract: A process for the production of lubricating-oils consists in polymerizing or condensing liquid or solid unsaturated hydrocarbons of the aliphatic, aromatic and heterocyclic series by the aid of A1C13, in reaction vessels constructed of materials which do not exert an unfavourable catalytic influence on the reaction.  Reaction vessels of Cr-coated iron, chromium, Cr-alloyed steels or Cr-Ni-alloyed steels are preferred. A1C13 containing less than 5 per cent of unsublimable residue is also preferred.  In an example, 100 parts of the liquid mixture of olefines resulting from the cracking of soft paraffin wax in the gas phase at 530 DEG  C. are placed in a vessel of steel containing 6 per cent of chromium, with 8 parts of A1C13. 200 Parts of a fraction of German crude mineral oil with a boiling point about 350 DEG  C. which has been pretreated with a little A1C13 are then added and the mixture vigorously stirred at about 45 DEG  C. for 2 hours.  The reaction mixture is poured into an NaC1 solution to destroy double compounds of A1C13 and hydrocarbons and, after removing the salt solution and sludge, the oil is washed, dried and fractionally distilled under a pressure of 1 mm. of mercury.  In addition to 15 parts of first runnings, 255 parts of a good quality lubricating oil suitable for motor cars, is obtained. By removing the oil boiling up to 285 DEG  C. by distillation, a residual oil of high flash point suitable for hot steam cylinder oil is obtained.  Aromatic hydrocarbons may be similarly treated.ALSO:A process for the production of lubricating oils consists in polymerizing or condensing liquid or solid unsaturated hydrocarbons of the aliphatic, aromatic or heterocyclic series by the aid of AlCl3 in reaction vessels constructed of materials which do not exert an unfavourable catalytic influence on the reaction.

Abstract: 1389486 Reciprocating pumps ARO CORP 16 March 1972 12472/72 Heading F1A A pump assembly for delivering a smooth continuous flow comprises a plurality of pumps 14, 16 with pistons 18, 36 continuously biased on their return strokes, and each selectively movable on their discharge strokes in response to the other or at least one of the others reaching a predetermined position on its working stroke. In the arrangement shown, pistons 18, 36 are actuated by air motor pistons 102, 104 continuously biased to the left by air-pressure from source 118 which also is connected to inlet ports 134, 148 of NOT logic elements 126, 140. In operation, during the discharge stroke of piston 36, the step between piston-rod portions 110, 112 actuates valve 156 to connect an accummulator 124 to exhaust via ports 128, 160, 164, line 176 and ports 174, 172. This causes logic element 126 to connect piston 102 to air-pressure for its discharge stroke and the air-pressure also is connected via restrictor 152 to accummulator 138 which, after a period determined by restrictor 152, charges to a sufficient pressure to actuate element 140 to cutoff air-pressure to piston 104 to permit its return stroke, during which valve 156 is reversed. Piston 18 then continues on its discharge stroke until valve 166 is actuated, resulting in actuation of piston 36. The connection of valves 156 and 166 by line 176 prevents stalling. Each pump 14, 16 has a piston-controlled inlet port 34, 50 connected to a supply reservoir, Fig. 2 (not shown), and a spring-loaded delivery ball valve 26, 42 opening into an outlet manifold 52. The motor pistons alternatively may be return-biased by springs.
