Title: Improvements in or relating to patterning mechanism for knitting machines
IPC: D04B15/74
Filed: 1931-01-19
Abstract: 365,777. Knitting-machines. SLACK & PARR, Ltd. and SLACK, H. A., Sideley Road, Kegworth, Derby. Jan. 19, 1931, No. 1706. [Class 74 (ii).] The web-holders, sinkers, or like instruments of a circular machine are selected for patterning purposes by a device comprising a disc 1 having radially disposed jacks 7 having one or more butts 10 so that they can be depressed as desired by cams or levers 101 to engage the sinkers. The cams 11 are held inoperative by springs 16 and are actuated by segmental cams 19 or other members of a pattern disc 17. After selection by the cams 11, the jacks 7 are raised by a cam 15. The pattern disc 17 is rotated by pawl-and-ratchet mechanism 22, 23, and the disc 1 is rotated by gearing from the needle cylinder. To enable the patterning to be nullified, cams 32, 33 controlled by the main pattern drum, are provided. The cam 32, when raised to operative position, raises all depressed jacks so that none of the sinkers is actuated ; the cam 33 is raised to such height as to engage butts 40 provided only upon the jacks 7 corresponding to the needles forming the foot bottom of a stocking, so that patterning may be continued on the instep while a plain foot bottom is formed. The disc 17 may be replaced by a pattern drum having its axis arranged horizontally above the levers 11. The invention is applicable to both rotary and stationary needle cylinder machines, and to rib and plain machines.

Title: Process for drying phosgene
IPC: C01B32/80
Filed: 1954-01-20
Abstract: Moist phosgene is dried by contacting with activated carbon, preferably at room temperature when the reaction, H2O + COCl2 --> CO2 + 2HCl takes place.  The phosgene may be passed through a drying chamber, e.g. a tower, packed with activated carbon.  Alternatively the phosgene may be contacted with the activated carbon in co- or counter-current flow.  In the separation of phosgene and hydrogen chloride in mixtures such as produced in the phosgenation of amines by passing the mixture through a condenser for the phosgene and subsequently through water for the absorption of the hydrogen chloride, a tube packed with charcoal may be inserted between the condenser and absorption vessel to prevent diffusion of water vapour into the phosgene.

Abstract: 1,162,351. Revolution direction indicators. COAL INDUSTRY (PATENTS) Ltd. Jan. 13, 1967 [Jan. 14, 1966], No. 1880/66. Heading G1K. [Also in Division H2] A voltage pulse indicative of the direction of rotation of an asymmetrical disc 1 mounted on the shaft of an electric motor is induced in an electromagnetic transducer (comprising a coil 4 wound round a permanent magnet 3) when the disc 1 is rotated in proximity to the magnet. The pulse is fed from the transducer (5 Fig. 2 not shown) to a thyristor (6) controlling a protective electric circuit, Fig. 3, for the motor. The motor is started by closing a switch 14 to energize a relay 12. If the motor is properly connected to rotate in the required direction a pulse will trigger the thyristor and contacts 11 will be made in a holding circuit for the relay 12; if the motor rotates the wrong way the pulse will be incapable of triggering the thyristor, contacts 11 will remain open and, when contacts 13 open after a predetermined time delay, the relay 12 will be de-energized and the motor will stop. The circuit 50 also includes an earth leakage relay 16, overcurrent relay 17, emergency push 18, thermal switch 19 and oil level switch 20. Alternative circuits are described with reference to Fig. 4 (not shown) and in another embodiment the thyristor output is applied to actuate a signalling device.

Change-giving apparatus; coin action, mechanicab-connection; money boxes or receivers.-Relates to a change-giving mechanism for use with prepayment gas meters and like apparatus, the coins used for operating such apparatus being obtained as change after the introduction of a coin of higher value. The apparatus is of the kind in which the coin of higher value dropped into a hopper is moved by a hand-operated slide to actuate a lever and free a disc or wheel cooperating with a change-removing slide. According to the invention, the stationary part connected with the introduction and movement of the coin of higher value consists of a shallow channel shaped guide 3, Figs. 1 and 2, having an outwardly projecting groove or tubular part extending along its back within which the push device 4 for moving the coin is placed and adapted to slide. The guides 3 has a flange 3<x> along one side for securing it to a vertical plate 1 by rivets 14, It has an opening at the top registering with a hopper 2 through which the coin of higher value o is dropped. The pusher 4 is flattened on one side to fit against the plate 1 and is connected by a rod 6 to an operating knob 5. The coin o actuates a lever 7 to remove a locking-bolt 10 from a toothed wheel 11 which is operated by a change-removing slide. The coin o drops through an opening in the lower flange of the casing 3 and, when the lever 7 is moved further by a cam 17 on the wheel 11, drops to a money-box.

Title: A process for the separation of monoalkyl phosphates from dialkyl phosphates
IPC: C07F9/02
Filed: 1954-01-29
Abstract: Monoalkyl phosphates are separated from dialkyl phosphates, the alkyl groups in the compounds containing not less than 5 and not more than 18 carbon atoms, by converting the mono- and di-alkyl phosphates into their alkali metal or alkaline earth metal salts, and dissolving the salts of the dialkyl phosphates from the mixture of salts so formed by extracting the mixture with one or more polar chlorinated hydrocarbons.  The polar chlorinated hydrocarbons may be chlorinated aliphatic, -cyclo-aliphatic or -aromatic hydrocarbons, chloroform being especially suitable. With chloroform the extraction may be effected at normal temperatures but when using certain other chlorinated hydrocarbons it may be desirable to heat the mixture. The alkali metal and alkaline earth metal salts may be prepared by adding solutions of the bases derived from the metals to the products of the reaction between phosphorus pentoxide and aliphatic alcohols or in those cases in which the bases are only slightly soluble in water, salts of the monoalkyl and dialkyl phosphates may be prepared from readily soluble bases such as sodium hydroxide and the ester salts produced then reacted with salts of bases which are only slightly soluble, e.g. magnesium chloride or nitrate. The residue containing alkali metal phosphate which remains after the separation of the alkali metal salts formed by converting the phosphorus pentoxidealiphatic alcohol reaction products into the alkali metal salts may be extracted with methanol or ethanol which dissolve the alkali metal salts of the monoalkyl phosphates and leave the alkali metal phosphate as residue.  Examples describe the extraction of sodium dimonyl phosphate and sodium diheptyl phosphate respectively from a mixture of the mono- and disodium salts and sodium phosphate formed from the products obtained by reacting phosphorus pentoxide with 3,5,5-trimethyl hexanol and n-heptanol respectively.  In each case the mixture is extracted with chloroform, dichloro-1,2-ethane, and dichloro-1,1-ethane, the extraction with the dichloroethanes being carried out at elevated temperature in a Soxhlet apparatus.
