Title: Improvements in or relating to the manufacture of cellulose
IPC: D21C3/02
Filed: 1935-07-11
Abstract: To obtain from wood, straw, grass and other lignin-containing cellulosic materials, a cellulose suitable for the manufacture of cellulose derivatives, artificial silks, and high grade paper, the cellulosic material is extracted with caustic alkali of 2\ba1/2\be--10 per cent concentration, at temperatures rising, either continuously or in stages, from 120 to 180 DEG  C., the treatment being an uninterrupted one, that is to say, throughout the treatment the whole of the material is in contact with the charge of alkali. As a further modification, or as an alternative, while maintaining the rising temperature conditions, the treatment is carried out either uninterruptedly or in stages, and with a considerable increase of the concentration of caustic alkali, the concentrations being however maintained within the limits 2\ba1/2\be--10 per cent.  In examples of treatment of poplar and spruce chips with 7\ba1/2\be per cent caustic soda, the following temperature steps are employed, (a) 130--140 DEG  C., 140--150 DEG  C., 150--160 DEG  C., 160--165 DEG C., and (b) 140--150 DEG  C., 150--160 DEG  C., 160--165 DEG  C. After the above alkali treatment, the material may be subjected to further purification as by treatment with cold concentrated alkali, a dilute alkali boil, or a bleaching operation with chlorine water, bleaching powder or hypochlorite.  Sodium sulphide, sodium sulphite, sodium chloride &c. may be added to the caustic alkali solution, in particular in the later stages of the treatment.  Specifications 263,938 and 312,098, [both in Class 2 (ii)], are referred to. According to the Provisional Specification, the caustic alkali may be replaced partly or wholly by sodium sulphide, sodium sulphite, sodium chloride, &c.

Abstract: 999, 158. Electrolytic testing apparatus. VARTA A.G. May 23, 1962, No. 19914/62. Heading G1N. The pores of a hydrogen diffusion electrode, used for determining the pH value of a solution, are initially purged with the solution whose pH is to be measured. Electrode 4 forms one wall of a gas space, within body 5, to which hydrogen is supplied through tubes 1, 2. With cocks 3, 7 adjusted to isolate container 8 from tube 1 and electrode 4, solution is admitted through gastight cover 10, and when the cocks are subsequently turned to the positions shown solution is forced through the pores of the electrode. Cock 7 may be replaced by a valve, or both cocks may be dispensed with if solution is injected into container 8 from a pump. A second method consists of reducing the hydrogen pressure so that solution is drawn in through the pores of the electrode. Electrode 4 consists of a fine-pored layer adjacent space 12 and a coursepored layer in contact with the solution to be examined.

Title: Improvements in or relating to hydraulic unloading valves
Inventor: PRICE WILLIAM RICHARDS
IPC: F16K17/08
Filed: 1961-06-02
Abstract: 940,674. Valves. FORD MOTOR CO. Ltd. April 19, 1962 [June 2, 1961], No. 20022/61. Heading F2V. When the pressure of a pump, connected to a port 38, exceeds a given level a relief valve 8 is lifted against a spring 9 and allows oil to pass across a seat 7 to a sump via passages 12, 14, a restricted orifice 17, a port 22, and a port 26 in a cylinder 2; the orifice 17 creates a back pressure in the passage 12 so that some oil passes through the metering orifice 28 in a one-way restrictor valve 27 and commences to slowly lift a spring- loaded piston 23 in the cylinder 2. When the latter has been raised sufficiently to cover the port 22, the oil in passage 14 can only escape by a restricted bore 20 and a port 21 so that pressure builds up beneath the valve 8 and lifts it further until a land 40 on the valve uncovers exhaust ports 13 whereupon the pressure will fall to a value depending upon the ratio of the areas of the land 40 and seat 7 and so unload the pump. Upon the pressure falling below the given level the valve 8 is reseated and the oil below the piston 23 unseats the valve 27 and slowly escapes through holes 29, the restricted bore 20 and port 21 until the piston 23 has descended far enough to uncover the port 22 whereupon the oil is then enabled to escape at a faster rate. The spring 9, which is pre-loaded by a distance piece 11, is enclosed in a chamber 4 across which oil from bore 20 flows to port 21; to provide stability of operation the valve 8 has a collar 41 slidable in the chamber 4, which collar has a small passage 42 therethrough to enable the fluid in chamber 4 to act on both sides thereof and so damp movement of the valve 8.

Filed: 1957-06-25
Abstract: 812,100. Sewing machines. PFAFF A.G., G.M. June 25, 1957 [June 30, 1956], No. 20033/57. Addition to 770,811. Class 112 The control arrangement of the parent Specification is modified to provide a time delay, after the foot-operated control switch has been depressed, before the solenoid actuating the belt-shift lever is energized to start the machine. As in the parent Specification, solenoid 19 is normally energized, to raise the work clamp, via main switch 17, rectifier 18, foot-operated control switch 23 and saftey switch 24. Solenoid 20, controlling the belt-shift lever, has interposed in its circuit a pair of normally open contacts 43, 45 of a relay 46. The coil 53 of the latter is connected to a transformer 56 via a rectifier 57, the normally open contacts 35, 37 of switch 23 and variable resistor 58. Coil 53 is shunted by a capacitor 59 via terminals 49, 50 of relay 46 normally closed by a movable contact 52. Capacitor 59 is shunted by a resistor 60 via the normally open terminals 47, 48 of the relay. When movable contact 38 of switch 23 is depressed to a position between the respective pairs of contacts 34, 36 and 35, 37, solenoid 19 is de-energized to allow lowering of the work clamp, and switch 24 is automatically opened. When contact 38 is fully depressed to close contacts 35, 37, coil 53 is energized after a time delay determined by the set valve of resistor 58. A movable contact 44 then closes contacts 43, 45 to energize solenoid 20 for starting the machine, contacts 49, 50 are opened to isolate capacitor 59 from coil 53, and a movable contact 51 closes contacts 47, 48 to connect resistor 60 in series with capacitor 59 for discharging the latter.

Abstract: 1513575 Stabilizing condensation products of phosphorus oxyacid esters STAUFFER CHEMICAL CO 13 May 1975 [28 May 1974] 20087/75 Heading C2P [Also in Division C3] A stabilized condensation product of one or more pentavalent phosphorus oxyacid esters at least one of which is a #-haloalkyl phosphate or a B-haloalkyl ester of an organic phosphonic acid is obtained by treating the product at elevated temperature with an amount of alkylene oxide or other oxirane compound for a period of time after residual acidity has been neutralized, the said amount and period of time being effective to open labile groups present and to neutralize the thus formed groups. Specified condensation products are the homocondensation product of tris(2-chloroethyl, phosphate, the co-condensation product of bis(2-chloroethyl)vinyl phosphonate and dimethyl methyl phosphonate or trimethyl phosphate, the homocondensation product of bis(2-chloroethyl)vinyl phosphonate and the co-condensation product of tris(2-chloroethyl)phosphate and dimethyl methyl phosphonate. After the residual acidity has been reduced, e.g. by treatment with an alkylene oxide, e.g. ethylene oxide for 1 to 4 hours, the further treatment with an alkylene oxide or other oxirane compound to effect the neutralization is generally effected at 90 to 140 C. and usually for a period of 2 to 12 hours. Examples are given for the stabilization product obtained by heating (ClCH 2 CH 2 O) 3 P(O) in the presence of a small amount of Na 2 CO 3  at 180 C. using ethylene oxide for removing the residual acidity and for the further neutralization treatment. The stabilized products are useful as flame-retardants and may be incorporated in a polyurethane-foam forming formulation.
