Title: Improvements in or relating to control apparatus for fluid-pressure operated motors of mining and other machines
IPC: F15B21/00
Filed: 1958-02-14
Abstract: 876,236. Mineral-mining machines. EICKHOFF, MASCHINENFABRIK UND EISENGIESSEREI GEB. Feb. 14, 1958 [Feb. 19, 1957], No. 4834/58. Class 68(1). [Also in Group XXIX] A valve suitable for controlling min ing machinery such as a fluid-pres sure motor 3 driv ing a cutting too and a fluid-pressure motor 5 driving a haulage device comprises a mov able member 2 con trolling the connec tion of either of the motors 3, 5 with a pump 1 and having biasing means 12 which urge it to a central position it which both of the motors are isolated from the pump and means for rendering the biasing means ineffective so that the member 2 may be moved manually or by other means to positions in which either of the motors is energised. The biasing springs 12 are compressed to free the member 2 by the application to plungers 11 of pressure in a control circuit fed by an auxiliary pump 9 which shares a common drive with the pump 1. Although the drive may be reversed to change the direction of operation of the motors 3, 5, the output from the pump 9 is made unidirectional by the provision of check valves 16. When the pumps 1, 9, are started up the output from the pump 9 lifts a spring-loaded valve 10 to obtain access to the inner sides of the plungers 11 to remove the biasing forces. Should either of the motors 3, 5 become overloaded the consequent rise of pressure in the delivery conduit from the pump 1 opens either of a pair of spring-loaded valves 18, 18<SP>1</SP> to enable pressure fluid to act upon a spring-load valve 20 which thereupon connects the conduit leading to the inner sides of the plungers 11 to sump causing the member 2 to be centred and the overloaded motor to be stopped. Due to the centring of the member 2 the pressure acting on the valve 20 is removed and the biasing forces of the springs 12 are again removed to permit manual operation of the member 2. A valve 14 bleeds fluid from the high pressure side of the pump 1 and this bleed is made up by a supply through valves 15 from the pump 9. This prevents overheating of the fluid in the main circuit. Valves 22 prevent overloading of the motors 3, 5 should the member .2 be moved suddenly to the central position.

Title: Manufacture and application of agents for improving textiles
IPC: D06M13/432
Filed: 1938-02-17
Abstract: 511,441. Delustring ; dyeing; biguanide derivatives. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Feb. 17, 1938, No. 4958. [Classes 2 (iii) and 15 (ii)] Oxyalkylated biguanides, prepared by treating an alkyl biguanide in which, the alkyl residue contains at least 10 carbon atoms with an alkylene oxide, are used for treating textiles for delustring, softening, levelling and in dyeing. The compounds may be used in the form of the soluble salts which they form with organic carboxylic or sulphonic acids, e.g., salicylates, glycollates and lactates. In examples, (1) Octadecyl biguanide (obtained by reaction of octadecylamine with dicyandiamide) is trated at raised temperature with ethylene oxide whilst stirring, and the base formed converted to salicylate; the resulting salicylate -of polyoxyethylated octadecyl biguanide imparts a soft feel to viscose and copper silk. Substantive dyeings are unaffected. (2) Zinc sulphide or titanium dioxide is made into a paste with water or alcohol and the product of example 1 ; the paste is dried and the 'resulting' powder makes a stable emulsion which delustres and softens artificial silk ; dyeings are unaffected. Other examples produce similar results employing other salts such as the hydroculoride, laurate and salicylate. Enhanced effects are obtained by adding an alcohol of at least'10 carbon atoms in which the carbon chain may be interrupted by one or more hetero-atom groups, e.g., - 0-, -CO.O- and -CO.NR-, including, fatty alcohols and their esters and ethers containing free OH groups, also esters and amides of soapforming fatty acids containing OH groups. Dyeing and matting may be etfected simultaneously, e.g., a pigment and a salt of the oxyalkylated biguanide is introduced into the dyeing bath.. The following acids form watersoluble salts with the oxyalkylated biguanideswhich do not alter the shade of dyed fabrics :- toluene-sulphonic-acid, di-isobutyl-naphthalene sulphonic acid, octadecyl-sulphonic acid, oleylmethylauride dodecyl sulphuric acid ester, tartaric acid, benzoic acid and naphthenic acid. Natural silk, wool, cotton, and other natural fibres as well as regenerated cellulose and cellulose organic derivatives may be treated according to the invention.

Filed: 1973-02-01
Abstract: 1367058 Capacitive memory cells INTERNATIONAL BUSINESS MACHINES CORP 1 Feb 1973 [20 March 1972] 5028/73 Heading H3T A capacitor data storage cell CS is refreshed during a read operation by a latch circuit 9. Data is read from CS by a F.E.T. Q1 in response to a low voltage on the word line 4. If a high level (1) is stored, a transistor 7 conducts to raise the bit line 5, and this triggers the latch 9 which is an SCR in Fig. 1. The latch acts to raise the voltage on line 5 above that which was necessary to initiate triggering, and this raised voltage is fed through another transistor 6 to refresh the storage cell CS. The capacitance of the line 5 is discharged by a transistor 12 which is turned on at the beginning of a read operation, but turned off before the word line 4 voltage is lowered to effect reading. Transistors 12 and Q1 are turned on together, however, if it is desired to write a "0" (i.e. CS is earthed). To write a "1" a further transistor 13 is turned on to raise bit line 5 to +V while word line 4 turns on Q1. Instead of the SCR 9, an emitter coupled pair (16, 17, Fig. 2, not shown) with a positive feedback emitter follower 20, may be used; this has to be reset by a transistor inverter 25. The collector load in the emitter coupled pair may be either a resistor, or (Fig. 3, not shown) a F.E.T. (31) with a gate-source capacitor which is precharged by a further F.E.T. 29 and which boosts conduction of the load F.E.T. (31). The load F.E.T. (31) is fed with a pulsed power supply which is high during a read (refresh) operation, but goes low thereafter and resets the latch by way of the feedback transistor (30).
