Patent GB-600800-A (GB)
Title: Improvements in or relating to the production of compositions containing synthetic resins for use as cements, coatings or the like
IPC: C08L21/00
Filed: 1947-06-18
Abstract: In a process for preparing a base for a coating or adhesive composition according to Specification 600,763, the non-heat-reactive phenol aldehyde resin contains up to 20 per cent of a heat-reactive phenol aldehyde resin (both resins being prepared from a phenol having an aliphatic substituent of at least 3 carbon atoms in the para-position), and the rubber is first blended with a major proportion of the nonheat-reaction resin containing all the heat-reactive resin, the blend being then incorporated in a heated solution of the remainder of the phenolic resin in the drying oil and the whole then being heated until the cooled mass has a desired consistency.  In the example, rubber reclaim is blended with an acid catalysed nonheat-reactive resin and a heat-reactive resin both prepared from p-tertiary amyl phenol, the resins being added gradually to the rubber on a roller mill.  The product is sheeted, broken up and treated with talc or soap solution to prevent sticking. The remainder of the nonheat-reactive resin is dissolved in dehydrated castor oil at about 270 DEG  F., the rubber-resin blend added and the whole heated at about 500 DEG  F. with stirring.  The mass is then cooled to about 300 DEG  F. dissolved in xylene, a portion of the solution worked up with titanium dioxide, blanc-fixe and china clay in a mill to a putty-like mass.  The balance of the solution is added together with a xylene solution of cobalt naphthenate and manganese naphthenate, and wood flour is incorporated into the mass.

Patent GB-1100963-A (GB)
Title: Stabilized polyalkylene oxides and process for preparing them
IPC: C08K5/00
Filed: 1965-04-20
Abstract: Polyalkylene oxides are stabilized by a mixture of the following compounds <FORM:1100963/C3/1> <FORM:1100963/C3/2> and (c) R4SnR5, in which K is a substituted, or unsubstituted benzene or naphthalene radical, R is a hydrogen atom or an alkyl, aryl or heterocyclic radical, R1 is an alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, A is -CH2- or -S-, R2 and R3 are alkyl radicals of 1 to 4 carbon atoms, n is 1 to 4 and R4, R5 are alkyl radicals or -(CH2)mCOOR6, in which R6 is an alkyl radical and m is 1 to 4. Suitable polyalkylene oxides are those obtained by polymerizing saturated alkylene oxides, halo-substituted epoxides, including epichlorohydrin, cycloaliphatic epoxides or epoxyethers, including glycidyl ethers, or by copolymerizing saturated epoxides with unsaturated epoxides, e.g. glycidyl acrylate. Typical examples of compound (a) have K as a benzene ring, R is methyl on the carbonyl group and hydrogen on the nitrogen, and R1 is the heptadecyl, benzthiazole, 1,2,4-triazole, benzotriazoles or imidazole radical. Typical examples of compounds (b) are bis (4 - hydroxy - 2 - methyl - 5 - t - butyl - phenyl)methane, and bis (4-hydroxy-2,5-di-t-butyl-phenyl)sulphide. Typical examples of compounds (c) are di(dodecyl)sulphide, di(octadecyl)trisulphide, and trisulphide (diacetic acid octadecyl ester).  The stabilizer may be added as a solid or in a solution.  The stabilized polymers may be dissolved or caused to swell, and may be cross-linked.  Swelling agents or solvents include: -dimethyl formamide, tetramethylene sulphone, dioxan, methanol, benzene, and chlorinated hydrocarbons. Soots, fillers, dyes or pigments, extender oils or lubricants may also be added.  The example describes the stabilization of a methanolic solution of a propylene oxide-allyl glycidyl ether copolymer, thiourea, silicic acid, zinc oxide, dipentamethylene thiuram tetrasulphide, 2-mercaptobenzothiazole, and titanium dioxide with a mixture of 2% the compounds (a) which have K as benzene, R on the carbonyl is methyl, R on the nitrogen is hydrogen, and R1 is heptadecyl or benzothiazole, 0.5% of bis(4-hydroxy-5 - t - butyl - 2 - methyl - phenyl) sulphide and 0.5% of di(octadecyl) disulphide, the percentages being based on the weight of copolymer. The resulting copolymer was spun and the filaments cross-linked.

Title: Method and apparatus for crushing and separating scrap material
IPC: B02C23/20
Filed: 1975-04-22
Abstract: 1466491 Dry separating AIR PRODUCTS & CHEMICALS INC 22 April 1975 [20 May. 1974 14 Aug 1974] 16615/75 Heading B2H Scrap material, having components such as ferrous metals which are rendered brittle by freezing, is passed through a cryogenic freezer to make these components non-ductile. The cooled scrap is then crushed in a mill 5 and thereafter sorted by a first air separator 7 into a "dust" fraction, a light fraction which is fed to a second crusher 13, and a heavy fraction which is fed to a magnetic separator 10. The magnetic fraction from the separator 10 is collected at 12, whilst the non-magnetic fraction is combined with the aforesaid light fraction for recycling through the crusher 13. The output from the crusher 13 is similarly treated by an air separator 16 and a magnetic separator 20, the light fraction from separator 16 being fed to a third crusher 23. After further magnetic separation and size reduction, at 26 to 35, non-magnetic values are collected at 37. The various magnetic fractions are also recovered, as at 12, whilst the "dusts" collected from the crushers and air separators may also be subject to the recovery of the metallic and non-metallic components thereof.  The non-magnetic fractions resulting from the above process may be treated by further apparatus to segregate e.g. aluminium copper, other metals, and non-metals. Such further apparatus may include a chopper to reduce the material to a uniform size; a multi-deck screen of progressively reduced screen size each screen having an oscillatory or reciprocating motion; gravity separators of the type having an inclined vibrating deck through which air is passed so that lighter material passes down the deck whilst heavier material moves uphill; and gravity tables comprising a meshed deck screen inclined in two directions, material on the screen being stratified into fluidised. layers of density by the passage of air through the screen and the resulting different fractions being recovered by the suitable placement of dividers.

Title: A new or improved device for sharpening safety razors

Filed: 1919-07-02
Abstract: 138,265. Roots, J. D., (SpecialitÚs et NouveautÚs Soc. Anon.). July 2, 1919. Stropping - apparatus &c.-A holder 32, Fig. 3, for a safetyrazor blade, is mounted on a carriage 20, which is reciprocated by means of a handle 24 to present the blade edge to a reversible stropping or honing surface 15 set at an angle to the path of the carriage, the upper fortion forming a strop whilst the lower surface is a hone. According as the blade is to be stropped or honed, the blade-holder is carried by one or the other of two pairs of bell-crank levers 26, 27, Fig. 2, pivoted at 23 on the carriage 20. Disks 35 at each end of the holder bear upon lateral guides, and the friction of these, combined with the pull of springs 30 on the levers 26, presses the bladeedge against the stropping-surface. At the outward end of the stroke, the blade leaves the strop, passes over a roller 42, and drops into the vertical position shown in Fig. 2 under the action of friction and of the spring 30. Flattened portions on the disks 35 determine this position. On the reverse stroke, the other side of the same edge is presented to the surface 15. On the commencement of a new stroke, the friction disks 35 reverse the blade and present its opposite edge to the strop. A stop 43 normally prevents the carriage from leaving the frame, but can be displaced, as shown in Fig. 2, to allow the carriage to move forward sufficiently to give access to the blade-holder for inserting or removing the blade.
