Patent GB-367102-A (GB)
Title: A manufacture of combinations of polyvinyl esters and fatty oils
IPC: C08F218/04
Filed: 1930-12-31
Abstract: Vinyl esters are polymerized in presence of a "low disperse phase" of a fatty oil, that is to say a polymerization product of a fatty oil which may be used as a whole, or the polymerization product may be first separated by the aid of solvents from the unchanged or less polymerized products.  Suitable solvents for separating the "low disperse phase" are aliphatic alcohols containing more than three carbon atoms, e.g. amyl alcohol or esters of aliphatic acids with monohydric alcohols, such as ethyl malonate, or mixtures of such an alcohol with such an ester.  Thus the polymerized oil may be dissolved completely by heating with the solvent, and on cooling the "low pressure phase" separates out; or the polymerized oil may be treated with acetone, the "low disperse phase" being insoluble in this solvent.  The polymerization of linseed, soya bean, perilla, and poppy reed oils is referred to.  Specification 15271/14, [Class 2 (iii), Dyes &c.], is referred to.ALSO:Vinyl esters are polymerized in presence of a "low disperse phase" of a fatty oil, that is to say, a polymerization product of a fatty oil which may be used as a whole, or the polymerization product may be first separated by the aid of solvents from the unchanged or less polymerized products. Suitable solvents for separating the "low disperse phase" are aliphatic alcohols containing more than three carbon atoms or esters of aliphatic acids with monohydric alcohols, such as ethyl malonate, or mixtures of such an alcohol with such an ester.  Thus the polymerized oil may be dissolved completely by heating with the solvent, and on cooling the "low disperse phase" separates out; or the polymerized oil may be treated with acetone, the "low disperse phase" being insoluble in this solvent.  The polymerization of the vinyl ester containing the "low disperse phase" oil may be effected in any manner, for instance by catalysis, pressure, illumination or the like, or by the process of German Patent No. 490,041.  Suitable additional substances may also be present, such as a resin, softening agent or solvent.  The proportions of ester and oil may vary widely and the proportion of oil may be as much as 95 per cent.  the products are suitable for the production of oil varnishes, coating compositions, adhesives, and plastics.  In the examples (1) vinyl acetate is mixed with "low disperse phase" linseed oil and the mixture is caused to react with benzoyl peroxide with heating; the polymerization is stopped when the mass becomes viscous by rapid cooling, the product being soluble in turpentine, sanquinaria oil, and tetrahydronaphthalene; (2) if the polymerization is carried further, an insoluble plastic product is obtained; (3) a mixture of vinyl acetate, vinyl butyrate, and "low disperse" soya oil is treated with benzoyl peroxide and polymerized by heat; (4) a mixture of vinyl butyrate, "low disperse" linseed oil, and benzoyl peroxide, is polymerized by heat.  Specification 15271/14, [Class 2 (iii), Dyes &c.], is referred to.

Abstract: 1314373 Valves ASTRO CONTROLS Inc 19 Aug 1970 [4 Sept 1969] 39978/70 Heading F2V A rotatable ball valve has the valve member, mounted between bearing seat rings 32, 32A e.g. of resin-bonded graphite, and adjacent the inner side of one of these rings is a flexible sealing ring 64, e.g. of P.T.F.E. which engages and can follow the valve member as it moves on to the downstream seat in closed position, so as to effect sealing irrespective of the flow direction through the valve. The sealing ring 64 is chevron-shaped, with the concave face thereof toward the adjacent seat ring, and is backed on the inside by a support ring 58 having a corresponding chevron-shaped recess. Thus the opening in the sealing ring 64 can contract radially under fluid pressure coming from the remote side of the valve member, so as to maintain sealing engagement with the valve member under this condition. The seat rings 32, 32A are slidable axially in grooves and backed by wavy springs (28) and 28A.

Class 100(4) A sensing device for a record controlled typewriter comprises, a guide platform adapted to accommodate both tape and punched cards and which is pivotally mounted for manual movement, from a loading position in which the tape or cards are aligned in the device, to a sensing position where the tape or cards are in engagement with feeding wheels. The guide platform comprises. a plate 13 and a spaced upper guide late 25 pivotally mounted on a shaft 15 on main castings 11, 12 and has at its front end a depending arm 16 carrying a pin 17 engaged by an over-centre spring 18. This retains the plate in either the lower sensing position where the tape or card is in engagement with feed wheel 33, or the loading position where the plate 13 is in its upper position and is engaged by a projection 20. The card is sideways inserted between the plates 13 and 25 until aligned along its edge by a spacer 14 interconnecting the two plates, and longitudinally by engagement with the projection 20 on the arm 21. A spring' finger 27 fixed on the plate 25 extends through an aperture 28 of the latter and includes a ball-point, member 29 which engages the drive holes of the card to act as a detent device while the guide platform is being moved from one position to the other. To load a tape into the device, a knob 22 is shifted from the position shown in Fig 4, used for card loading, to the other end of a slot 26 where a bar 30, moved by the knob 22 engages an upwardly turned lip of the guide 25 to move the plate just away from the projection 20 so that a tape can be sideways inserted. Sensing of punched holes in the records is by pins 53, Fig. 5, pivotally connected to arms 55 whidh are allowed to move upwardly once each cycle by an electromagnet and a cam mechanism 65, 66. Specification 750,454 also is referred to.

Abstract: 1,020,523. Shearing. WELLMAN ENGINEERING CORPORATION Ltd. Oct. 21, 1964 [Oct. 23, 1963], No. 41837/63. Headings B3Q and B3W. [Also in Division B5] An apparatus for working on rods, bars or tubes comprises means for feeding the material in a given direction and a tool for operating on the material during the feeding displacement of the latter, the tool being displaceable in said given direction at a speed which bears a predetermined relationship to the speed of feeding displacement, the feeding means and means for displacing the tool each comprising an hydraulic piston and cylinder assembly and the assemblies being linked together by a common hydraulic system. Feeding means.-The work material passes through the hollow piston rods 6 and 7 of two coaxial assemblies 1 and 2, and is gripped on the forward stroke (from left to right in the Figure) by self-engaging grippers 1a and 2a respectively. Forward movement of the pistons 8 and 9 is effected by high-pressure fluid from a pump, not shown. Return movement of the pistons is effected by a low-pressure fluid from a pump 10 which is connected to the forward end of each cylinder through non- return valves 12 and 13. Fluid exhausted from the assemblies 1 and 2 on the forward stroke passes via non-return valves 14 and 15, a relief valve 16, a flow control valve 17 and a solenoidoperated valve 18, to the left-hand end of a third cylinder assembly 3. The high-pressure fluid supply to the assemblies 1 and 2 is controlled by valves, not shown, so that the pistons 8 and 9 move forward alternately, the forward movement of one piston begins just before the other piston reaches the end of its stroke, so that for a short time both pistons are moving forward together. Displacement of tool.-The tool 5, which is described as a mechanically-operated shear, but may also be a rotary disc cutter, a saw or a stamping or notching device, is mounted on the hollow piston rod 4, through which the work material passes. The leading end of the material operates an electric switch, positioned a desired distance beyond the assembly 3, which energizes the solenoid a of the valve 18 to admit fluid to the left-hand end of the assembly 3. The piston 19 is then driven forward by fluid displaced from the assemblies 1 and 2 and the tool 5 operates during the forward stroke. At the end of the stroke of the piston 19, the valve 18 is reversed and the piston 19 makes its return stroke. The areas of the faces 8a, 9a and 19a of the pistons 8, 9 and 19 are the same so that the piston 19 moves at the same speed as the pistons 8 and 9. The feed means may also be used to draw work material through a die.
