Title: Process for preparing an alpha-copper phthalocyanine pigment
IPC: C09B67/12
Filed: 1975-04-24
Abstract: 1492224 Copper phthalocyanine pigments HOECHST AG 24 April 1975 [6 May 1974] 17046/75 Heading C4P Highly pure unsubstituted α-copper phthalocyanine pigment is produced by after-treating an α-copper phthalocyanine regenerated from its sulphate in an aqueous medium containing a polar aliphatic, cycloaliphatic or heterocyclic organic compound having up to 8 carbon atoms in the molecule, which is entirely or partly water-soluble or liquid under the conditions of the after-treatment. The after-treatment is preferably effected at temperatures from 15 to 80 C. The polar compound may be an alcohol, ketone, ether, carboxylic acid, ester, nitrile, amide lactone or lactam. A preferred product comprises an α-copper phthalocyanine having a specific surface area of 50 to 80 m<SP>2</SP>/g and a ratio of the intensity differences between the maxima at 12À1  and 13  respectively and the minimum at 12À6  in its X-ray diffraction spectrum diagram of from 1 : 10 to 1 : 4. The pure α-copper phthalocyanine may be used for pigmenting colourless material, e.g. plastics, particularly polyvinyl chloride and for the preparation of dyeing compositions. The copper phthalocyanine used for the after-treatment is preferably obtained by converting CuPc by means of 70-100% sulphuric into a salt which is subsequently hydrolysed in water and the resulting CuPc is suction filtered and finely divided in an aqueous suspension by means of a kneading device, high-speed stirrer having a grinding effect, a vibratory mill, ball mill, bead mill or other mill. Reference has been directed by the Comptroller to Specification 1,459,427.

Title: Improvements in devices for controlling the positioning of movable machine parts, such as the work-tables of machine tools
Inventor: PEGARD PIERRE
IPC: B23Q5/52
Filed: 1950-07-11
Abstract: 673,299. Machine-tool details. SOC. ANON. DES ATELIERS G.S.P. GUILLEMIN-SERGOT & PEGARD. July 11, 1950, No. 17326/50. Class 83 (iii). For controlling the positioning of a machinetool table, a rotatable grooved drum d is fitted on the table and carries stops k which are located by means of gauges l interposed between said stops and a fixed reference part at one end of the drum. A drum d, indexable by a hand wheel vb and pawl cb is mounted on each of the lead-screw-operated compound tables of a radial-arm drilling-machine and the shouldered stops k are located by gauge-rods l housed in the drum grooves. The shoulder on each stop is so related to the total length that, when reversed in the slot, the distance z is equal to the width of the stop-switch feeler n and the stop can be used to arrest the traverse at the same position regardless of the direction of traverse. For each indexed setting of each drum, the appropriate stop first contacts the sloping end of either a feeler m<SP>1</SP> or mll, according to the direction of traverse, and operates a switch q<SP>1</SP> or qll to slow down the traverse motor; more than one slow-down feeler may be provided on each side of the stop feeler n in order to slow down the traverse by degrees. Finally, the stop moves the feeler n and plate n<SP>1</SP> sideways to open one of the stop switches r<SP>1</SP> and r<SP>11</SP>. For reversing the direction of traverse, if required, after indexing the drum from one position to the next, stops i<SP>3</SP> may be fitted as required in holes in the drum and they operate a feeler i<SP>2</SP> to close a switch i<SP>1</SP> in a reversing circuit.

Title: Process for finishing artificial silk
IPC: D01D10/04
Filed: 1934-06-13
Abstract: In a process for finishing viscose artificial silk which has been de-acidified or de-acidified and after-treated on the spool, and then dried, the threads are thoroughly wetted and subjected p  to a twisting operation from which they are received in the form of a self-supporting winding or in the form of a cake and in this form are after-treated if they have not been after-treated on the spool.  The twisted threads may be received in a centrifugal box or on a rotating plate which also has a reciprocating movement or a component which is a reciprocating movement, e.g. as described in Specifications 6356/05, [Class 2], 414,991, and 434,881.  When the thread is received in a centrifugal box it may be doubly twisted by rotating the twisting spindle and the box so that they both twist in the same sense.  In an example viscose silk on spools is de-acidified, freed from sulphur by a suction washing treatment, bleached, soaped and dried.  The spool is mounted on a twisting spindle and the thread is drawn off overhead or over a galette or draft device consisting of a number of rollers, thoroughly wetted on or behind the drawing device by a wet sponge or thread guide kept wet and is deposited on a plate disc driven by planet gearing as described in Specification 434,881. The plate may have a central upwardly projecting piece in the form of a truncated cone.  The after-treatment may be performed on the windings after twisting by sucking forcing liquids through them, the windings being advantageously secured by binding with threads or covered with permeable cloths.  In another example the thread after wetting with water or soap solution is collected in a light centrifugal box, e.g. of sheet aluminium, driven by a belt, and of such diameter that a thick conical pin may be inserted within the cake produced to transfer it to a manufacturing machine.

Abstract: 713,763. Change-speed gear. WILLYS MOTORS, Inc. July 24, 1951 [Aug. 19, 1950], No. 17522/51. Class 80 (2) [Also in Group XXXI] Relates to a vehicle power take-off mechanism (see Group XXXI) in which the power take-off unit is connected to the engine through a planetary gear mechanism. The input and output shafts 74, 88 of the usual vehicle changespeed gear are hollow to accommodate a shaft 150 connected to the engine crankshaft 63 at its front end and at its rear end engaging a sleeve 153 carrying the sun gear 154 of the planetary gear, the planet gears 163 of which are carried by a member 160 connected by a shaft 157 to the power take-off shaft 53. The annulus of the gear is carried by a drum 165 having a sleeve-like extension 167. The drum 165 is adapted to be engaged by brake shoes 180 which are operated by rotating a plate through a link 191 by a hand lever 176 which also controls through a member 174 a clutch member 172 which can connect the extension 167 to the output shaft 88. The arrangement is such that the brake and clutch are not operative together and a third position of the lever 176 leaves the annulus of the gear free so as to disconnect the power take-off unit from the engine operation of the brake causing the planetary gear to operate as a reduction, gear and operation of the clutch causing a direct drive of the shaft 53 from the engine if the shafts 150. 88 are rotating in unison. Specification 617,972, [Group XXXI], is referred to.

Abstract: Carboxyl-bearing compounds are separated from the residual liquid obtained in the desugarization of molasses or formed as vinasse in the fermentation of carbohydrate-containing liquids by concentrating said liquid, diluting the mass thus obtained with an organic liquid or mixture of organic liquids miscible therewith, which liquid or mixture may or may not be diluted with water, adding, either in admixture with said organic liquid or separately, an acid whose salts with the cations present in molasses are difficultly soluble or insoluble in the liquid medium, separating the resulting precipitate, evaporating the organic liquid, and passing the remainder through one or more ion exchangers.  The residual liquid is preferably concentrated to a water content of 40-25 per cent by volume. Preferably 0.6 to 2 kg. of organic liquid is added per kg. of concentrated residual liquid, specified organic liquids being methanol, ethanol and acetone.  The quantity of acid used is preferably such that the pH is between 3.5 and 1, specified acids being sulphuric, sulphurous and phosphoric.  The precipitate of insoluble salts is preferably caused to form at a temperature above that of the surroundings or, alternatively, solution and precipitate are preferably heated to a temperature above that of the surroundings (temperatures between 35 DEG  and 80 DEG  C. are preferred in both cases), the whole in each case being subsequently cooled to room temperature and the precipitate and liquid separated.  The remainder after evaporation of the organic liquid is preferably passed through an anion exchanger and subsequently, if desired, through a cation exchanger.
