IPC: B62D11/08
Abstract: 1,037,523. Clutch control, friction clutches. S.A. FRANCAISE DU FERODO. Jan. 27, 1964 [Feb. 2, 1963], No. 3438/64. Headings F2C and F2L. A control for sequentially disengaging two clutches 24, 24<SP>1</SP>in a selected order comprises two pedals 11, 11<SP>1</SP>respectively connected to clutch release forks 34, 34<SP>1</SP>,through linkages 36, 40, 41, 42; 36<SP>1</SP>,40<SP>1</SP>,411, 421 and connected to each other through a lost motion coupling 13 so that depression of one pedal 11 (or 11<SP>1</SP>) initially acts on its release fork 34 (or 34<SP>1</SP>) to disengage the associated clutch 24 (or 24<SP>1</SP>) and takes up the lost motion in the coupling 13 whereafter further movement of the pedal 11 (or 11<SP>1</SP>) acts through the coupling 13 to disengage the other clutch 24<SP>1</SP>(or 24). As shown the linkages comprise a cam plate 40 fast with the pedal 11 which plate co-operates with a follower 41 on a lever 42 connected through a rod 45 with the release fork 33. The cam plate 40 has an inclined portion BC which effects clutch disengagement and an arcuate portion CD which retains the fork 33 in the clutch disengage position during further movement of the pedal. The clutch pedals 11, 11<SP>1</SP>and levers 42, 42<SP>1</SP>are biased towards the clutch engaged position by springs 35, 44. The clutches 23, 24<SP>1</SP> which connect an engine-driven input flywheel 22 to two concentric output shafts 21. 21<SP>1</SP> respectively driving a tractor mains transmission and power take-off comprise driven discs 24, 24<SP>1</SP> splined to the output shafts 21, 21<SP>1</SP> and clamped between the flywheel 22 and presser plates 23, 23<SP>1</SP>by diaphragm springs 28, 28<SP>1</SP>.The clutch release forks 33, 33<SP>1</SP> act through thrust bearings 32, 32<SP>1</SP>on inner fingers 30, 30<SP>1</SP>of the springs. In Figs. 7-9 (not shown) the cam and follower are replaced by springs which transmit the initial pedal movement to the release fork whereafter the spring abuts a stop so that subsequent movement of the pedal compresses the spring. The lost motion coupling 13 may be arranged so that disengagement of the second clutch commences simultaneous with, prior to or after completion of disengagement of the first clutch.

Abstract: 1,050,642. Polyesters, foamed polyurethanes. FARBENFABRIKEN BAYER A.G. Jan. 8, 1964 [Jan. 11, 1963], No. 922/64. Headings C3C and C3R. A polyester containing OH groups is derived from a polyhydric alcohol and a polycarboxylic acid obtained by reacting a cracked petroleum fraction with an α,#-unsaturated dicarboxylic acid or anhydride. The cracked petroleum fraction may contain saturated hydrocarbons, olefines, dienes, cyclohexene, and cyclopentadienes and may have a density of 0À76-0À81 g./ml., a boiling range between 40‹ and 200‹ C. and a bromine number of 50-80 g./100 ml. Unsaturated acids and anhydrides specified are maleic, fumaric, itaconic, citraconic and methylene malonic acids and maleic anhydride. The addition reaction may be at 130-250‹ C. and optionally at superatmospheric pressure. If free radical initiators are present, e.g. dicumene and cumyl-tert.-butyl peroxides and azodiisobutyronitrile, the unsaturated carboxylic acids are simultaneously polymerized. Polyols specified for polyester formation are: mono-, di- and tri-ethylene glycol, propane-1,2-diol, butane diol, hexane diol, hexane triol, trimethylol propane monoallyl ether and their ethoxylation and propoxylation products. Other dicarboxylic acids may also be used, e.g. adipic, isophthalic and terephthalic acids and phthalic anhydride. The polyesters should have an OH number of 40-600 and an acid number below 50. Polyurethanes may be produced by reacting, the polyesters with polyisocyanates, e.g. tolylene diisocyanate, m- and p-phenylene diisocyanate, diphenyl-methane diisocyanate and adducts of tolylene diisocyanate with trimethylol propane and hexamethylene diisocyanate and diphenyl methane diisocyanate with water. Masked isocyanates can also be used. Other reactants which may be present are: blowing agents, e.g. water, and low boiling organic solvents such as CCl 3 F, polyamines, alkanolamines, e.g. tetrapropoxylated ethylene diamine, polyols, other polyesters and polyethers. The reaction may be in one or more steps. The products may be used as lacquers or may be moulded. In examples the following materials are also present during polyurethane formation: a polysiloxane/ polyalkylene glycol copolymer, permethylated N,N<SP>1</SP>-bis-aminoethyl piperazine, and a 50% aqueous solution of sodium castor oil sulphonate.

Photo-conductive copy-sheets of increased spectral sensitivity are obtained by incorporating a 4 - amino - naphthal - 1,8 - imide in the photo-conductive layer of the copysheet. Photoconductors such as ZnO or In 2 O 3 , together with insulating binders such as a butadiene-styrene polymer are ground in toluene and a dispersion of the 4-amino-naphthal-1,8-imide in a solvent such as methanol, dimethyl formamide, toluene, methyl-isobutyl ketone, ethanol or triethylaminea dded thereto. Alternatively, the sensitizer may be added in the solid state and ground in. The composition may be coated on an aluminium foil or aluminium paper laminate. Other sensitizers may also be used, e.g. Patent Blue, Phloxine B and Setoflavine. The 4-aminonaphthal-1,8-imides which are preferably used are those of formula where Z 1  and Z 2  are H or SO 3 M (M being H or a cation such as Na<SP>+</SP> or (C 2 H 5 ) 3 HN<SP>+</SP>); R 1  and R 2  are H, alkyl e.g. CH 3  aryl or aralkyl; Y is H, NH 3 , phenylamino, sulfoethyl, isopropyl, p-tolyl, pyridyl, diethylaminophenyl, 4-hydroxy - 3 - carboxyphenyl, tetradecyl; other substituent groups are also exemplified. The sensitizers may be used in amounts 0À005- 2,000 parts per 40,000 parts of photoconductor. A yellow 4-aminonaphthal-1,8-imide may be used to increase sensitivity to blue light.

IPC: B01D29/11
Abstract: 1,052,157. Automatically-cleaned filters for liquids. BRASCO S.A. April 14, 1965 [April 17, 1964], No. 15986/65. Heading B1D. Unfiltered liquid introduced at 5 passes outwards through a perforate screen 6 into a common admission chamber 3 and passes thence through annular passages 12a &c., each surrounding a tubular member 10a &c., acting as a holder for a porous filter element 11a &c., depending into a sector-shaped cell 1a &c. From all but one cell the liquid filters inwards through the element to reach a common exit chamber 4 having an outlet 7. One element at a time (e.g. 11a, as shown) is cleaned by engagement of a rotating cam 16 with the stem 15a of a valve 14a permitting communication between cell 1a and a common discharge chamber 8 having an outlet 9. The cam is so shaped that the valve is first suddenly opened to its maximum extent and for a short time only, then suddenly partially closed, being maintained in this partially closed position for an appreciably longer time, and then closed for the remainder of the cycle. In the first of these stages, a transient pressure-reversal occurs across the filter element, sufficient to dislodge the cake without much loss of filtered liquid; in the second stage the extent of valve opening ensures pressure-equalisation across the element, so that the element is washed by flow of unfiltered liquid along it from annular passage 12. In the third stage normal filtering occurs, so that where twelve elements are provided the first two stages together occupy only one twelfth of the cycle for any one element. A more complex embodiment is described, its main differences from Fig. 1 being (a) the provision of several (e.g. seven) filter elements per cell; (b) the provision of a woven sheath on each element as actual filtering surface, of such a size that it has one or more folds under inlet pressure, and blows out to break up the cake on pressure reversal; (c) the provision of a resilient disc, with a central hole, in the upper end of each tubular member, so arranged that the hole is enlarged by liquid flow in the "backflush" stage only, to provide greater backflow. Where a granular filter adjuvant is used, the outlet 9 may be connected to a hydrocyclone or similar device, (Fig. 10, not shown), from which a "residue" fraction and an "adjuvant" fraction are discharged separately, the latter preferably being re-circulated by a pump to inlet 5. Further cams may be provided to effect simultaneous cleaning of several cells.

Abstract: 1,084,333. Acrylonitrile polymer filaments. COURTAULDS Ltd. June 12, 1964 [June 13, 1963], No. 23572/63. Heading B5B. [Also in Division C3] Crimped or crimpable fibres in the form of staple fibres, spun yarns, or continuous filaments or threads are derived from copolymers containing a major proportion of acrylonitrile units and from 7 to 20 mol per cent of units of an N-methylol-ethylenically unsaturated acid amide, e.g. N-methylol-acrylamide or -methacrylamide, or a latent derivative of such an N-methylol compound, e.g. one where the methylol group is etherified or replaced by an aminomethyl group. The copolymer may optionally contain units of an additional component, e.g. acrylamide and/or methallylsulphonic acid or a salt thereof. The fibres may be obtained by wet- or dry-spinning methods; the preferred method comprises extruding an aqueous sodium thiocyanate solution of the copolymer into water or a dilute sodium thiocyanate solution, and stretching the fibres obtained by at least 500% in hot water or steam. The fibres may be dried under tension or, having been dried when relaxed, may be strained by stretching again. The stretch-strained fibres develop crimp on being heated to above their second order transistion point (always below 100‹C.); fibres dried under little or no tension can be crimped directly. The crimp can be set by cross-linking the methylol-amide or latent-methylol amide groups in the copolymer, cross-linking being catalysed by acids, e.g. H 3 PO 4 , and certain salts, e.g. MgCl 2 , or by the presence of units of an acidic monomer (e.g. the aforementioned methallyl-sulphonic compounds) in the copolymer. Heating can effect simultaneous crimping and cross-linking.
