Title: Improvements in or relating to resinous condensation products
IPC: C08F2/36
Filed: 1945-04-09
Abstract: Oil-soluble resins are prepared by interpolymerizing a vinyl aromatic hydrocarbon, such as styrene, vinyl naphthalene or divinyl benzene, with a methylene quinone compound in the presence of a catalyst.  The methylene quinone compound is preferably in the form of a phenolic resinous product containing more than 15 per cent by weight of methylene quinone.  Both the ortho and para forms may be used and these may be halogenated or alkyl-substituted, monomeric or polymeric.  Unless the product is to be oil-modified in situ, e.g. by reacting with tung oil, dehydrated castor oil or linseed stand oil, the reaction is preferably carried out in a volatile solvent such as carbon tetrachloride, petroleum ether or benzene.  The methylene quinones may be prepared by the action of alkali on "pseudo phenol halides," these compounds being made by halogenation of phenol alcohols or halomethylation of phenols; or when oil-soluble alkali condensed phenol-formaldehyde resins are submitted to heat polymerization.  Examples are given of styrene interpolymerized with 3,5-dimethyl-2-quinone methide, 3,5 - dibromo - 2 - quinone methide, the resinous product obtained by heating the dialcohol of p-xylenol and treated phenolic resins, using stannic chloride or borofluoroacetic acid as catalyst.  Varnishes are prepared by thinning the resin in white spirit and/or heavy naphtha.

Filed: 1973-02-23
Abstract: 1425184 Sewing machines G TOLLE 23 Feb 1973 [6 May 1972] 8912/73 Heading D1G In a sewing machine having the needle 16 below the work and the loop taker 21 above it on a bracket arm which can pivot upwards, a work clamp 30 comprises upper and lower jaws, both supported on a base plate 40 which can also pivot upwards about a pin 41. The upper jaw 73 pivots about a pin 72 carried by the lower jaw, and carries a work engaging shoe 75 which presses the work against a tray 62 on the lower jaw. To move the work clamp while sewing a buttonhole for example, a belt 94 drives a sprocket clamped to an internally threaded sleeve 92, and so moves a threaded stud shaft 91 inside it. The stud Shaft is attached via an angle bracket 90 and a resilient mounting to a block 83 which slides in a groove 84 in the base plate and is attached to a sliding plate 80. As the sliding plate moves along the base plate the lower jaw is forced to slide at an angle to it because it carries blocks which slide in diagonal slots in the base plate. If the base plate is raised the tongue 100 which pivots on a pin 101 and is accommodated in a block 103 allows the sliding plate to be raised also. The base plate normally presses down against a spring biassed stud 130. To provide a constant distance between the loop taker and work of varying thickness the bracket arm carries a sliding rod 113 to which is attached a wheel 110 which presses against a track 77 on the work clamp. When the bracket arm is lowered the rod carrying the wheel is pressed upwards until a pin 116 which it carries reaches the end of a slot 115.

Abstract: 600,241. Regulating. SPERRY GYROSCOPE CO., Inc. June 7, 1943, No. 9150. Convention date, June 6, 1942. [Class 7 (vi)] In a device for suppressing detonation and comprising a detector responsive to vibrations caused by detonations and adapted to control automatically the working conditions of the engine, the automatic control means modify the position of an engine control member which is also manually adjustable. A detonation detector 22, Fig. 1, such as that described in Specification 533,499, actuates a visual signal device 25 and, through a relay 23, excites a solenoid 37, Fig. 3, to draw in a hollow armature 48 and displace fluid past a ball valve 56 to move a piston 40 connected by a link 15 to a fuel control lever 14, the mixture being enriched to suppress the detonation. As shown, the piston 40 operates in a casing 31 filled with oil and the armature 48 pumps oil from a right-hand chamber 34 to a left-hand chamber 35 of which the piston 40 forms a wall. Oil thus transferred, leaks back to the chamber 34 through a passage 59 controlled by a screw 60 and excessive movement of the piston is prevented by a passage 61 opening into the space behind the piston by an aperture wider than the depth of the piston. The casing 3] and its parts make up a control unit 20 which is mounted on the fuel detent lever 19. Instead of actuating the fuel lever, the piston 40 may adjust the ignition timing.
