Title: Improvements in or relating to clutches
IPC: F16D13/64
Filed: 1936-08-01
Abstract: 473,378. Friction clutches. BORG & BECK CO., Ltd., and HIGGS, C. W. Aug. 1, 1936, No. 21365. [Class 80 (ii)] In a clutch plate comprising a disc carrying a facing at each side, wherein at least one facing is mounted on one set of resilient tongues struck out from or secured to the disc and, after a predetermined amount of compression, it coacts with another set of tongues so as to give a two-stage action, the tongues of each set are identical in shape and size, are offset by equal amounts from the plane of the disc, and are distributed across the radial width of the facing, so that the latter tends at all times to remain parallel with the disc. As shown in Fig. 1, the disc 10 is formed at intervals with gaps so shaped that each provides a group of four tongues 16 .. 19 of identical shape and size. The tongues are deflected laterally, the diagonally-opposite tongues 16, 18 being deflected to a greater extent than the tongues 17, 19, and one facing 11 is attached to the tongues 16 by rivets 21. The tongues 16, 17 are interchanged in successive groups, and the tongues of each group may all converge on a single point. The other facing may be rigidly secured to the disc by rivets 13, or the groups of tongues may be bent alternately to opposite sides of the disc so as to afford a two-stage resilient mounting for both facings. As shown in Fig. 8, the disc 10 is cut so as to provide groups of six tongues 27 ... 32, of which the tongues 27 .. 30 are equally deflected while the tongues 31, 32 are deflected to a less extent. The facing 11 is secured by rivets 25, 26 to the tongues 27, 28. Specification 434,019 is referred to.

Title: Improvements in the decomposition of phosphates
IPC: C05B11/06
Filed: 1937-08-04
Abstract: In a process of decomposing water-insoluble phosphates with nitric acid and recovering solid calcium nitrate from the reaction liquid, temperatures not exceeding 25 DEG  C. are maintained during the decomposition using nitric acid of medium strength, so that the calcium nitrate separates at least in part by the time decomposition is completed.  Nitric acid of 55-65 per cent by weight may be used, and by using a predetermined excess thereof and neutralizing the mother liquor comprising phosphoric and nitric acids with ammonia mixed fertilizers having a predetermined N2 : P2O5 ratio may be obtained.  For example, by using 20 per cent excess of 60 per cent nitric acid, a fertilizer having a 1 : 1 ratio of N2 to P2O5 may be produced.  The calcium nitrate obtained may include an acid salt of the formula 3Ca(NO3)2.12H2O.HNO3, and when 63 per cent acid is used this salt is exclusively produced.

Abstract: 521,687. Cracking hydrocarbons. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges. July 21, 1938, Nos. 21679 and 23365. [Class 32] Non-knocking motor fuel is obtained by cracking a hydrocarbon oil, especially a heavy benzine or middle oil obtained by the reduction of carbon monoxide, by passing the oil in liquid or vapour phase at cracking temperature and at an initial pressure of 1-100 atmospheres through a reaction zone containing a cracking catalyst and increasing the pressure in the reaction zone continuously or step-wise by at least 5 atmospheres, preferably 10 atmospheres or more, while the catalyst is acting on the oil, without interruption of this process. The temperature may also be increased by at least 10‹C. In an example, a paraffinic middle oil is fed, at a temperature of 460‹C. and at atmospheric pressure, into a reaction chamber filled with pieces of bleaching earth and the pressure is gradually increased to 30 atmospheres over 90 minutes. The reaction product is cooled, first with water and then with solid carbon dioxide, the permanent gases being collected in a holder ; the condensate contains 35 per cent. benzine. In a second, similar, example the temperature is also increased to 480‹C., the benzine yield being 40 per cent.

Abstract: 1,183,961. Xerographic plate. RANK XEROX Ltd. 10 May, 1967 [13 May, 1966], No. 21765/67. Heading H1K. [Also in Division C1] A xerographic plate of improved humidity stability incorporating a glass binder, is made by exposing the surface of the plate to selenium at an elevated temperature. The plate may be dipped in molten selenium, exposed to selenium vapour with or without helium as a carrier gas, or the vapour sprayed on to the surface. The plate may be treated near the glass softening point and after treatment washed and scrubbed to remove any iridescent film. The treatment is said to replace surface oxygen by selenium and thereby inhibit ionization of surfaceabsorbed water. The glass binder may be made from a selection of the oxides of Si, P, Ti, B, Al, Sb, As, Na, Ca, Li, K, Mg, Ba, Pb, Zn and Cd and NaF and preferably incorporates as a photoconductor CdS, Cd 2 SSe, CdSe or Zn 2 SSe but other photoconductors are specified. The binder incorporating the photoconductor may be coated on a plate of Al, brass, stainless steel Cu, Ni or Zn or conductively coated glass to give a xerographic plate.

[Also in Divisions A5 and D2] An absorbent article for absorbing body wastes, for example a disposable napkin for a baby, comprises a core of highly absorbent material covered with a surface layer of internally-plasticized wet-strength paper. The paper is plasticized with a non- migratory plasticizer in an amount sufficient to reduce the hard and rattliness of the paper but insufficient for there to be loss of plasticizer from the paper when the paper is kept at a temperature of 120F. for three days. The plasticizer may be a polyethylene glycol and the amount of glycol added to the unplasticized paper preferably is from 5% to 50% by weight based on the weight of the plasticized paper; the glycol may be applied to the paper by saturating the paper with an aqueous solution of glycol and thereafter evaporating the water. Alternatively, or additionally, the plasticizer may be a non- crystallizing sorbitol or sorbitol ether, for example a lower hydroxyalkyl ether of sorbitol such as hydroxypropyl sorbitol. A blend of plasticizers may be used. The paper may be made of bleached cellulose stock obtained from either softwood or hardwood pulp; alternatively, the paper may be made of fibres other than wood fibres, for example hemp fibres. The paper may include a water-insoluble bonding agent, for example a synthetic resin or preferably glue or regenerated cellulose; - when the fibres of the paper are bonded by a proteinaceous bonding agent, the paper may include an inhibitor, for example ethylenediaminetetraacetic acid in an amount of from 0.01% to 0.1% by weight based on the weight of the paper, to prevent enzyme action on the paper. The paper also may include migratory plasticizers (for example glycerine), perfumes (for example of the coconut extractsynthetic vanillin type) and bacteriostatic agents (for example a quaternary ammonium compound such as para-diisobutylphenoxy ethoxyethyl dimethyl benzyl ammonium chloride). The absorbent core, which may be a mass of cellulose fibres having substantially no wet-strength, may be made of water-leaf multi-ply crepe wadding or sulphite cellulose fluff, or a defibred flock of bleached soft-wood Kraft fibres, or degreased cotton linters, or combinations thereof. Figs. 1 and 2 illustrate a disposable napkin for a baby in which napkin an absorbent core, formed by a mass of wood fluff 2 enclosed in a layer of no-wet-strength tissue paper 4, is disposed between two cover layers 5 and 6 of the internally-plasticized wet-strength paper, the layers being overlapped as shown and being spot bonded to the tissue paper at 7 and 8, respectively.
