Title: Data processing system with improved subsystem communication
IPC: G06F5/06
Filed: 1967-05-23
Abstract: 1,142,290. Computers. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23867/67. Heading G4A. A processor uses a command and address to obtain a word from memory, the word then being sent to a device specified by a portion of the word. Access to a plurality of memories by " functional units ", viz. processors and input-output-devices controllers, is via memory controllers, one for each memory. Each inputoutput-devices controller is associated with a particular memory controller, by a manual or programme-controlled switch, for data transfer, and each memory controller is similarly associated with a particular processor to receive CONNECT commands. When a memory controller accepts a CONNECT command, which is accompanied by an address, from its associated processor, decoding of this command causes the address to be used to access a word from the attached memory, and the word to be gated to one of the " functional units " above along a respective bus, as selected by (say) three bits of the word, decoded to a 1-out-ofselection. The buses may be used for other types of transfer. The 1 bit of the 1-out-of-8 selection accompanies the word. The word may be data, or it may cause generation of a second address and carrying out further operations in accordance with information stored at the second address. In the case where the destination is an input-output-devices controller the word may alternatively be a command word selecting, and causing operations within, a particular input-output-device linked to that controller. The command word may cause address generation and processing in the destination controller.

Title: Improvements relating to tipping or dumping wagons
IPC: B61D9/02
Filed: 1920-08-16
Abstract: 171,753. Westinghouse Brake Co., Ltd., (Oppermann, G.). Aug. 16, 1920. Hopper wagons.- The discharge doors of hopper wagons are actuated by means of compressed air or vacuum in connection with a train pipe independent of the brake system of the train, a reservoir capable of being charged from the train pipe being provided on each vehicle for use when the wagons are to be discharged independently. Each vehicle carries a cylinder A fitted with a piston which is moved in the directions indicated by the arrows X, Y respectively to close or open the discharge doors, and a reservoir B, connected as shown by pipes S, M, K, L, cocks C1, C2, E, Fig. 1, and non-return valve D to the train pipes H, J, which may be isolated on each vehicle by cocks F, G. If the doors are to be operated simultaneously, compressed air is admitted to the train pipe J from which it passes by way of the pipe L, the cock C2 set in the, position I, Fig. 2, and pipe N, to the cylinder A to open the door. To close the door, the pipe J is opened to the atmosphere and compressed air is admitted to the pipe H, which, acting through the pipe K, valve C1 set in position I, and pipe M, moves the piston in the direction X. To operate the doors individually, the reservoir B is charged with compressed air from the train pipe H by way of the valve E, non-return valve D, and pipe S, compressed air at the same time passing by way of the pipe K, cock C1, and pipe M to the cylinder A to close the door. Both train pipes H, J are then opened to the atmosphere on the locomotive or on each vehicle. To open the door, the, cock C2 is placed in position II, whereby the left-hand end of the cylinder A is placed in communication with the reservoir B. On returning the cock C2 to position I, the cylinder A is opened to the atmosphere. To close the door, the cock C1 is turned into position II, placing the right-hand end of the cylinder A in communication with the reservoir B, whereby the piston is moved in the direction Y. The reservoir B is of sufficient capacity to actuate the doors several times. The system may be actuated by vacuum instead of compressed air, in which case the non-return valve D is reversed, or if the doors are to be actuated in one direction by a spring, one train pipe with its connections may be dispensed with.

Patent GB-480117-A (GB)
Title: Improvements in the manufacture and production of products having wetting, emulsifying and like properties
IPC: C09K23/00
Filed: 1936-09-02
Abstract: Mixtures containing polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols and/or carboxylic acids containing at least 6 carbon atoms in the molecule and impurities such as high molecular hydrocarbons, aldehydes, ketones or esters are freed from the latter by an extraction process whereby the wetting, washing and emulsifying properties of the products are improved. The mixtures are dissolved in an organic water insoluble solvent, a water soluble organic solvent of low molecular weight is added and two layers then produced by the addition of the requisite amount of water.  The polyglycol ether derivatives are then separated from the solution in the low molecular solvent. Advantageously, the major portion of the highly oxyalkylated constituents are first separated from the other constituents by treating with aliphatic or cycloaliphatic hydrocarbons, ethylether or acetone.  The initial materials may be obtained by treating the higher alcohols or carboxylic acids with alkylene oxides such as propylene oxide, glycide, epichlorhydrin or di- or tri-ethyleneglycol in the presence of sodium or potassium ethylate, soda, sodium acetate, bleaching earth or active carbon. Suitable higher alcohols or carboxylic acids are obtained by the oxidation of paraffin wax, paraffinic or naphthenic oils, hydrogenation products of coals, tars or carbon oxides.  The products of the oxidation may be freed from saponifiable constituents and subjected to reduction.  The saponification products of fats, oils and waxes and reduction products thereof may also be subjected to alkoxylation.  In examples: (1) hydrogenated unsaponifiable products of oxidized hard paraffin wax are reacted with ethylene oxide and the resulting alkoxylated mixture is treated with benzine; the residue which is soluble in water has emulsifying power and disperses calcium soaps; the benzine layer is mixed with ethyl alcohol and water, and the aqueous layer, after further extraction with benzine is evaporated to give a product which has washing properties; (2) the starting material used in example 1 is subjected to a similar purification process but ethyl ether is used instead of benzine; the product has foaming properties; (3) an acid product obtained by oxidation of hard paraffin wax with air is distilled and the first fraction reacted with ethyleneoxide; the product is subjected to a similar purification process to that used in example 1. Specification 367,003 is referred to.
