Title: Improvements in or relating to manufacture of polymer-resin granules
IPC: B29B9/00
Filed: 1952-12-30
Abstract: Granules of water-insoluble polymers of molecular weight 10,000 or higher, e.g. synthetic resins and cellulose derivatives, which have uniformly dispersed therein a water-in-soluble resin, e.g. a natural resin or a synthetic resin of molecular weight below 10,000 are made by suspending granules of the polymer in a suspension medium, e.g. water, containing a suspending agent, mixing the granules and the resin in the presence of a small p  proportion of a solvent which is a solvent for the polymer and resin but substantially insoluble in the suspension medium and recovering the polymer-resin granules.  In the case of synthetic resins the resin may be added as a step in a bead polymerization process by allowing the polymerization to proceed to the desired extent, stopping the reaction by adding the resin, and either utilizing the residual monomer as the solvent or adding an appropriate solvent.  Plasticizers may also be incorporated in the polymer with the resin.  In the case of cellulose derivatives, granules may be obtained by mixing a solution with water in the presence of a suspending agent.  Specified polymers are polyvinyl acetate, polyvinyl chloride, polyvinyl butyrate, polyvinyl formate, polymethyl methacrylate, polystyrene, a copolymer of methyl acrylate and vinylidenechloride, polyvinyl acetal, polyvinyl butyrate, ethyl cellulose, cellulose acetate, and nitrocellulose.  Resins mentioned are hydrogenated, polymerized, disproportionated or esterified, e.g. with pentaerythritol, rosins, coumarone, damar, copal, polyterpenes, e.g. alpha pinene, alkyds, resinous chlorinated diphenyls, rosin-modified phenolics, maleic rosin adduct ester, oil-soluble phenolic resins, wood resins, run Congo, run Macassar, run Kauri, Elemi gum, Manila, gum Pontianac, East India gum, and mixtures.  The suspending agent may be polyvinyl alcohol or magnesium carbonate and the plasticizer dicyclohexyl phthalate.  Solvents mentioned are ethyl acetate, chloroform, toluene, vinyl acetate, methyl acrylate and vinylidene chloride.  The polymer-resin beads may be used as adhesives, e.g. for milk cartons and book-bindings, for coatings and in moulding operations.

Title: Control valve
IPC: B60T11/34
Filed: 1973-07-12
Abstract: 1414057 Proportioning valves; differential braking; valves WAGNER ELECTRIC CORP 12 July 1973 [12 July 1972] 33179/73 Headings F2F and F2V An hydraulic proportioning valve 1 situated between the master cylinder and the front axle brakes of a vehicle hydraulic braking system has an inlet port 10 and an outlet port 18 and a proportioning piston 19 with a valve member 23 which is co-operable with a valve seating member 24 to meter the pressure in the outlet port 18 with respect to the pressure in the inlet port 10: the proportioning piston 19 has an extension 25 which extends into an atmospheric chamber 44 which also receives a drive piston 35 and the piston 35 is acted upon by the pressure in the inlet port 10 so that at a predetermined inlet pressure the piston 35 is moved to alter the metering operation of the piston 19 and at a higher predetermined inlet pressure the piston 35 abuts the piston 19 to bring about totally unrestricted communication between ports 10, 18. As shown, the seating member 24 is provided with an aperture 30 through which piston 19 extends and side 32 of the member 24 constitutes a valve seat. The seating member 24 has a peripheral lip 33 and a plurality of axially extending return flow passages 34 normally closed by the lip 33. The sealing engagement of piston extension 25 with a seal 9 defines an effective closing area A 1 , the sealing engagement of valve member 23 with seating member 24 defines an effective area A 2  and the sealing engagement of a seal 36 on the drive piston 35 defines on effective area A 3 ; A 2  is greater than A 1  and A 3 #(A 2 -A 1 ). In its inoperative position a shoulder 28 on piston 19 abuts a shoulder 17 in the housing 1 and when hydraulic pressure P is supplied to inlet port 10 a pressure P 0  is initially established at the outlet port 18 equal to pressure P. However the pressure P 0  acts over the area A 1  to tend to close the valve 23, 24 and when force P 0 A 1  (that is initially PA 1 ) exceeds the force Fc of a spring 29 the valve 23, 24 closes. Thereupon the supplied fluid pressure P acts on an area A 2 - A 1  to give a force P(A 2  - A 1 ) additive to force Fc and as pressure P increases these combined forces will cause valve 24 to open to effect an increase in pressure P 0 . The process continues to effect a proportionate increase in pressure P 0  as pressure P increases until the pressure P which also acts on the effective area A 3  of piston 35 via a passage 12 from the inlet port 10 reaches a value sufficient to urge piston 35 rightwards against the force F 3  of a spring 43 to move piston 35 into abutting engagement with piston extension 25. The net force PA 3  - F s  on piston 35 is now additive to the input force P(A 2  - A 1 ) acting on the piston 19, and the ratio of pressure P 0  to pressure P is now increased. However a pressure P is eventually reached which causes pistons 19 and 35 to move rightwardly to bring shoulder 28 into abutment with shoulder 17 to hold the valve 23, 24 in open position to allow unrestricted communication between ports 10, 18.

Title: Method of and apparatus for controlling the cooling of a hollow mandrel in a metal-extrusion press
IPC: B21C31/00
Filed: 1957-10-25
Abstract: 840,457. Extruding. SCHLOEMANN A.G. Oct. 25, 1957 [Nov. 24, 1956], No. 33351/57. Class 83 (4). The hollow mandrel of a metal extrusion press is cooled alternately by liquid and gas. The mandrel 3 is cooled during extrusion by a liquid coolant and after extrusion when the temperature has fallen below a minimum limit the liquid coolant is replaced by a gas coolant. Hot billets 31 of steel or brass are extruded by a ram 1a from a container 28 through the annular gap between the mandrel 3 and a die 29. The ram is operated by an hydraulic piston 21 and is retracted by drawback plungers 24 working in hydraulic cylinders 25 of the vertical press frame 26. During extrusion water is supplied to the mandrel through solenoid valve 48, pipe 9, throttle valve 10, flow meter 52. check valve 51, and pipes 9, 8, 7. The solenoid 49 of valve 48 is energized to open the valve during the downstroke of the ram by a crosshead 23 closing a limit switch 42 which controls the solenoid through a relay and timing box 44. After extrusion the mandrel is retracted and the crosshead 23 then closes a switch 41 which acts through relay box 44, producing a predetermined time delay of about 3 seconds, to de-energize solenoid 49 and energize solenoid 46 controlling a compressedair valve 12. Thus the water is shut off and air is admitted through pipe 11 and pipes 9, 8, 7 into the mandrel 3 to blow out the water through ducts 2a, 6. After a further time delay of about 5 seconds the air valve 12 is closed. Limit switch 41 may be omitted and the temperature of the withdrawn mandrel is then detected by a radiation responsive device 60 which controls the water and air valves through an amplifier 62, compensator 64 and the relay box 44. The supply of water and air may also be controlled manually by the valves 10, 12.

Abstract: 849,254. Colour television. ZENITH RADIO CORPORATION. Oct. 25, 1957 [Oct. 26, 1956], No. 33372/57. Class 39(1). A method of making a luminescent screen composed of a multiplicity of areas in a colour television tube of the shadow mask variety, comprises forming the screen areas by a process including the step of exposing radiation-sensitive material disposed on the screen through the mask apertures to radiation originating in an effective point source centred in one of the electron sources of the tube, the radiation being directed upon the mask through a refracting field having an axis of symmetry which lies in the plane containing the source and the tube axis and is inclined to the tube axis at an angle which is such that the axis of symmetry intersects the tube axis in e point more remote from the screen than the field and which has a tangent of the same order of magnitude but not exceeding #A /#C where #A is the maximum radial shift of the effective electron source due to convergence effects and #C is the maximum axial shift of the source due to deflection of the electrons. In Fig. 10, an optical source is shown positioned at the blue colour centre 21 for printing through a shadow mask 26 on to a screen 27 using a combination of an optically symmetrical refractive member 45 with a prismatic member 48 arranged with one of its prism surfaces parallel and in contact with a plane surface of the member 45, the axis of symmetry 49 of the member 45 passing through the source 21 and making an angle # with a line 34 parallel to the tube axis such that tan # = #A/#C. The apparent light source then follows the locus 21 41<SP>1</SP>, 42<SP>1</SP> of the effective blue electron source. In Fig. 12, the refracting field is introduced by a refractive member 45 with its centre 47 lying on a line 34 through the source 21 parallel to the tube axis 23 and with its axis of symmetry 50 making a similar angle # with the tube axis. Other refractive members e.g. a piano-concave lens a plane parallel plate or a zero curvature lens may be used. Specification 821,615 is referred to.
