Abstract: 1449503 Valves D C MALONE 14 Nov 1973 [15 Nov 1972 25 Oct 1973] 52825/73 Heading F2V [Also in Division Fl] In a dispenser of the type in which liquid in a container is discharged by air pressure generated by an integral pump and passing through a check valve into the container manually actuable means are provided for unseating the cheek valve to release the pressure in the container. A valve is also provided to limit the pressure generated by the pump. As shown in Fig. 2 the pump has an outlet check valve 228 and an inlet valve 242 in the piston. A member 252 passes through the hollow piston-rod 232 and carries a normally closed valve 250 which may be raised by the actuator 252 to release pressure in the pump barrel and on further movement to lift the valve 228 to relieve pressure in the container, as shown in Fig. 12. At a given pressure the valve 250 snaps through the slot to relieve the pressure in the barrel as shown in Fig. 11.

Sodium from the reactor 81 is pumped into the distillation chamber, 1, where it fills the containers, 23, which are then heated electrically. The sodium in 23 evaporates, leaving solid impurities which may be examined in the compartment 6 by raising the cover, 13, which supports 23.

Title: Improvements in and relating to the manufacture of integrated circuit devices
IPC: H01L21/00
Filed: 1969-10-30
Abstract: 1281933 Integrated circuit manufacture INTERNATIONAL BUSINESS MACHINES CORP 30 Oct 1969 [19 Nov 1968 (4)] 53126/69 Heading H1K In a method of manufacturing an array of integrated circuits on a common semi-conductor wafer involving the use of masks in successive processing steps, a group of masks is made for each step, the location of faults on individual masks determined, and a set of masks selected with reference to this information to provide an optimum yield of good circuits from the method as a whole. Selection is made in such a way that the random faults occurring in the various masks are as far as possible in corresponding positions but it takes account, by weighting, of the fact that manufacturing defects not attributable to mask defects have a higher incidence at the periphery of the wafer than at its centre. Where the masks for the different steps vary in complexity and hence in the average number of faults per mask, this average is determined experimentally. The number of masks of the most complex group needed to give a required yield of good circuits is calculated, and then the correspondingly smaller number of the less complex masks to maintain this yield. Selection is made with the aid of a computer into which fault location and weighting information is fed, or optically by superimposition of transparent sheets with blocked-out areas corresponding to faulty areas in individual masks. In the latter case comparison may be made visually or with the aid of photo-cells. Optimum results are achieved by comparing all possible mask combinations at the outset but only marginally worse results can be obtained with far less expenditure of time by taking the best mask from the first group, selecting the mask of the second group which combines with it to give the best result, then choosing the mask of the third group combining best with the selected first and second masks and so on. When using this sequential technique the mask for a given step need only be chosen on completion of the preceding step, at which time more and possibly technically superior masks may have become available for selection. In the embodiment the masks are used for exposing photoresist in the formation of diffusion and electrode etching masks.

Abstract: 532,700. Wetting &c. agents. I. G. FARBENINDUSTRIE AKT.-GES., and STANDARD OIL DEVELOPMENT CO. July 26, 1939, No. 21758. Convention date, July 27, 1938. [Classes 2 (iii) and 15 (ii)] The oxygen containing non-alcoholic compounds present in the products obtained by the oxidation of high molecular hydrocarbons are reduced to alcohols and the constituents containing less than eleven carbon atoms in the molecule are removed; Products having wetting, washing, cleansing and foaming properties are obtained by sulphonating the alcoholic mixture thus produced. The high molecular fractions of crude oil, naphthenic hydrocarbons, sweater oil, products obtained by the hydrogenation of carbon oxides, crude scale wax and refined wax may be used as starting materials. The desired alcoholic mixture may be obtained from the oxidized products by fractional distillation, selective extraction, sweating, pressing or centrifuging. In an example, crude scale wax is blown with air in the presence of a manganese catalyst, the mixture treated with alkali and the resulting soap extracted. The remaining mixture of oxidized hydrocarbons is treated with methanol to separate the bulk of the unattached hydrocarbons and the oxidation products, after removal of the solvent reduced by means of hydrogen and a nickel catalyst. Low boiling alcohols are separated by fractional distillation and the remaining alcoholic mixture is sulphonatea. Specification 489,863 is referred to.

[Also in Division C3] Acrylonitrile polymer fibres have dispersed throughout their cross-sections 0À05 to 3% by weight of a salt of a partial ester of orthophosphoric acid with a monoalkyl ether of a polyoxyalkylene glycol. The salt may be the sodium salt. The monoalkyl group may contain at least 10 carbon atoms. The salt may be a sodium salt of a lauryloxypoly(ethyleneoxy) acid phosphate having the formula wherein n is 1 or 2 and x is about 4. The acrylonitrile polymer may comprise at least 85% by weight acrylonitrile and up to 15% by weight of a monoethylenically unsaturated monomer copolymerizable with acrylonitrile. A mixture of aliphatic hydrocarbons having an average chain length at least corresponding to that of a mineral oil or a paraffin wax may be dispersed as an extender throughout the crosssection of the fibre together with the salt. The salt may be in the form of rod-shaped globules with their longitudinal axes extending in the direction of the fibre length. The fibres of the invention may be made by dry or wet-spinning a solution of the polymer and the salt in an appropriate solvent such as N,N-dimethyl formamide. The spinning solution may contain the salt and the mixture of aliphatic hydrocarbons in the form of an aqueous emulsion. In an example, an N,N-dimethylformamide solution containing 31% by weight of total solids is provided by dissolving in the solvent a terpolymer consisting of 93À6% acrylonitrile, 6% methyl acrylate and 0À4% sodium styrenesulphonate; 0À4% TiO 2 , based on polymer weight; and 0À25%, based on polymer weight, of a mixture of 40% paraffin wax and 60% of the sodium salt of a mixture of mono- and di-esters of orthophosphoric acid and an alcohol prepared by condensing lauryl alcohol with 4 mols. of ethylene oxide.

A signal on lead 103d is then fed to the digital indicator 27 to correctly position the decimal point. The time interval TP may also be adjustable for different sizes of vehicle wheels and toothed gears.
