Title: Oil-soluble polymer composition
Inventor: AGIUS PETER JOSEPH VERMONT JAM
IPC: C08F220/16
Filed: 1955-05-04
Abstract: Improved detergency properties are conferred upon lubricating oils, particularly animal, vegetable or mineral oils, by the addition thereto of an oil-soluble composition obtained by the polymerization of a mixture of an anil and an unsaturated monomer containing a single unsaturated double bond.  Suitable unsaturated monomers of this type are alkyl esters of acrylic, methacrylic, maleic and fumaric acids wherein the alkyl group preferably contains 8 to 18 carbon atoms (e.g. lauryl methacrylate), styrene, alkylated styrenes, unsaturated ethers, halides and sulphides, and esters of unsaturated alcohols.  The anils are obtained by the reaction of an amine with an aldehyde or ketone; the anil used may be either saturated, e.g. benzanil, or unsaturated, e.g. the reaction product of laurylamine, butylamine or aniline with acrolein or crotonaldehyde.  The polymeric product is preferably added to lubricating oils in a proportion of less than 30 per cent by weight.ALSO:Oil-soluble polymer compositions are obtained by the polymerization of an anil and an unsaturated comonomer containing a single unsaturated double bond, e.g. alkyl esters of acrylic, methacrylic, maleic and fumaric acids wherein the alkyl group preferably contains 8 to 18 carbon atoms, such as lauryl methacrylate, styrene, and alkylated styrenes, and unsaturated ethers, halides, sulphides and esters of unsaturated alcohols. The anils are obtained by the reaction of an amine with an aldehyde; the anil used may be either saturated, e.g. benzanil, or unsaturated, e.g. the reaction product of laurylamine, butylamine or aniline with acrolein or crotonaldehyde.  Polymerization may be initiated with the aid of catalysts, such as tert.-butyl hydroperoxide, benzoyl peroxide, 1-hydroxycyclohexyl hydroperoxide, sodiomalonic ester, sodium ethoxide, sodium ethyl magnesium bromide, stannic chloride, ferric chloride, sulphuric acid and azodiisobutyronitrile, or by means of ultra-violet or beta- or gamma-radiation.  In an example lauryl methacrylate is polymerized in bulk in the presence of benzanil, and optionally in the presence of lauryl alcohol as a modifier, which gives a product more readily soluble in oil.

Title: Mass-coloration of linear polyesters
Inventor: COOPER ALBERT CHARLES
IPC: C07D471/04
Filed: 1965-03-26
Abstract: Linear polyesters are mass-coloured with dyestuffs of formula <FORM:1094528/C4-C5/1> where one of A and B represents a 1:2-phenylene radical and the other of A and B represents a 1:2-phenylene, 1:2-naphthylene, 2:3-naphthylene, 1:8-naphthylene or 5:6-acenaphthylene radical, and the said radicals together contain at least one group of formula <FORM:1094528/C4-C5/2> where R represents a hydrogen atom or an alkyl, hydroxyalkyl or alkoxyalkyl radical, X represents an alkylene or phenylene radical, n represents 1 or 2, and A and B optionally contain further substituents other than sulphonic acid groups.  Specified further substituents are chlorine, bromine, lower alkyl, nitro and cyano.  The dyestuffs may be made by condensing a diamine of formula <FORM:1094528/C4-C5/3> with an anhydride of a dicarboxylic acid of formula <FORM:1094528/C4-C5/4> the compounds containing between them one or two -(CO-X-)n-1COOR groups.  They may also be made by reacting conventional phthaloperinone or naphthoylene benziminazole dyestuffs with a dicarboxylic acid in a FriedelCrafts reaction.  Dyestuffs containing a carboxylic ester group may be obtained by esterifying the corresponding dyestuff containing a carboxylic acid group in conventional manner.ALSO:Dyes used to mass colour linear polyesters have the general formula <FORM:1094528/C3/1> where one of A or B represents a 1:2-phenylene radical and the other of A and B represents a 1 : 2-phenylene, 1 : 2-naphthylene, 2 : 3-naphthylene, 1 : 8-naphthylene or 5 : 6-acenaphthylene radical, and the said radicals together contain at least one group of formula -(CO-X-)n- 1-COOR where R represents a hydrogen atom or an alkyl, hydroxyalkyl or alkoxyalkyl radical, X represents an alkylene or phenylene radical, n represents 1 or 2, and A and B optionally contain further substituents other than sulphonic acid groups.  Specified further substituents are chlorine, bromine, lower alkyl, lower alkoxy, nitro and cyano. The dyestuffs may be tumbled with chips of the polyester which are subsequently melted and melt spun or the dyestuffs may be added during the preparation of the polyesters.  Dyestuffs containing carboxyl groups may be used in the form of their ammonium salts which give rise to the free acids during the heat treatment required to melt the polyesters.  The preferred polyesters are those of terephthalic acid and glycols of formula HO-(CH2)x-OH where x is 2-10 or 1 : 4-di(hydroxymethyl)cyclohexane. In the Examples, the dyestuffs were added to preformed polyethylene terephthalate or during the ester-interchange or polycondensation reaction used in preparing this polyester from dimethyl terephthalate and ethylene glycol.

Abstract: 835,182. Valves. SOC. TECHNIQUE ET COMMERCIALE D'INSTALLATIONS INDUSTRIELLES LUCEAT. April 23, 1958 [April 23, 1957], No. 12963/58. Class 135. A valve comprises an apertured plate 30 mounted on a shaft 25 and a sleeve 37 which may be pressed against the plate by a transversely-movable wedge 41 which is at one side guided in a cap 23 and at the other side connected to an actuating screw 19 carried in a cap 13. The wedge has an aperture to register with the flow passage through the valve and is connected by dovetail tongues (not shown) with the sleeve 37 so that the latter is positively withdrawn from engagement with the plate 30 when the wedge is raised. The sleeve 37 is sealed by an 0-ring 38 held in place by a screwed ring 39. Each side of the plate 30 has a pair of grooves to receive sealing-rings 32, 33 which coact with the end of the sleeve 37 and with the end of a sleeve 34 screwed into the valve housing when the plate is in the open and closed positions. The plate is enclosed by a pair of detachable caps 8, 9 of which the latter is fitted with a valve 7 for detecting leakage. The plate is keyed to the shaft 25 in such manner that it may move axially and not bind on the end of the sleeve 34. The operating arm 27 for the shaft 25 is formed with a ring 28 at its outer extremity so that its position may be readily seen at a distance. The wedge 41 may be made of bronze and the bearing surfaces of the sleeves 34, 37 chromium-plated. In a modification, for higher pressures, the arcuate edge of the plate 30 remote from the shaft 25 is guided by balls or rollers, the arrangement being such that when the sleeve 37 is withdrawn from engagement with the plate spring loaded balls or rollers on the same side of the plate as the fixed sleeve 34 urge the plate into engagement with fixed balls or rollers on the other side. A compression spring encircling the shaft 25 also urges the plate in the same direction. In cases where high pressures may act on both faces of the plate 30 movable sleeves 37 and wedges 41 may be provided on each side of the plate in which case fixed rollers on each side of the plate are provided. The actuating lever 27 may carry near its outer end a nut mounted on trunnions for engagement by a screw-threaded actuating spindle carrying a hand wheel.

Title: Hose nozzle
IPC: A62C31/02
Filed: 1945-05-24
Abstract: 597,416. Spray producers ; rotary cylindrical valves. NIELSEN, A. May 24, 1945, No. 13036. [Classes 69 (iii) and 135] A hose nozzle, particularly for fire-extinguishing apparatus in which a jet or annular spray or a combination of both may be produced, includes a valve chamber 15 disposed between a coupling connection 12 and a nozzle barrel 14, the latter having a central nozzle tube 19 communicating at one end with the chamber 15 by means of a primary port 17 and terminating at the other end in a discharge nozzle 20, a venturi nozzle 21 being mounted concentrically in the tube by means of radial ribs 22. An annular passage 23 between the tube and the nozzle barrel terminates in an annular conical spray orifice 27 formed in an adjustable sleeve 25 rotatably mounted on the end of the nozzle barrel, and communicates with the chamber 15 by a secondary port 18. Rotatably mounted in the chamber 15 is a valve yoke 28 having a central aperture and carrying valves A, B slidable in slots 35 in the yoke and urged outwardly against the wall of chamber 15 by springs 38. Valves A, B are so shaped and positioned that rotation of the yoke by means of a handle 39 from the position shown in which valve B covers both ports 17, 18, first causes valve B to uncover port 18, thereby producing a conical spray from orifice 27. Further rotation of the handle uncovers both ports and produces both a solid jet from orifice 20 in addition to the conical spray. A subsequent rotation of the handle to its rearmost position causes valve A to cover port 17 so that only the solid jet issues from orifice 20.

Title: Improvements in or relating to friction clutches
IPC: F16D25/062
Filed: 1956-04-28
Abstract: 825,709. Friction clutches. MONKS, H. June 18, 1957 [April 28, 1956], No. 13080/56. Class 80 (2). In a fluid pressure operated friction clutch a main pressure space 11 is formed between an axially movable clutch disc 6 and a carrier 1 carrying a clutch member 5, an initial pressure space 19 is also formed between the carrier and the disc, and valve means are provided whereby pressure is first admitted to the initial pressure space for light engagement and then to the main pressure space for full engagement, the initial pressure space being closed at one side by an internal annular flange 7 on the clutch disc sliding on a sleeve 8. Two clutches according to the invention are mounted on a shaft 2 to provide alternate drives to gears 9 of a twospeed gear. Each gear 9 has a sleeve 8 with teeth 14 engaged by teeth 13 on the clutch discs 6 which are urged to the disengaged position by springs 15 until the discs abut a spring ring 12. Fluid pressure is fed from bores 20 in the shaft 2 to passages 22 in the carrier 1, and by passages 23 to the initial pressure space 19 which is sealed by the flange 7 to the sleeve 8 and by an annular surface 18 and a spigot 3 on the carrier. On initial engagement the clutch surfaces 16, 17 engage, after which pressure builds up in the passage 22 to open a spring-loaded valve 25, housed in a counterbore 24 in the carrier, to allow pressure to enter the main pressure space 11 through a passage 30 for full clutch engagement. The valve 25 comprises a roller in a square passage 31 the passage being tangential to a circle concentric with the carrier 1 to obviate the effects of centrifugal force, though the passage may be given a slight inclination if it is desired to aid or oppose the spring 26. When the valve 25 is closed the space 11 is vented through a passage 29.
