Abstract: 872,026. Shutters. PERKIN-ELMER CORPORATION. Feb. 12, 1960 [Feb. 13, 1959], No. 5087/60. Class 98(1) A shutter of the louvre type for controlling the passage of radiant energy is characterised by each blade being resilient and being fixedly supported at both ends, all the supports lying substantially in a common plane, and all the blades being controlled by means formed with two sets of teeth, associated with opposite halves of the blades, each tooth lying between two adjacent blades, and being arranged so that relative movement between the control means and the blades perpendicular to the longitudinal axis of the blades in a plane parallel to the plane of the supports will cause the teeth to engage the blades and twist them between an opened and a closed position. As shown (Fig. 5), the apparatus comprises an apertured base plate 10 and two apertured actuating plates 24, 26 which have sets of teeth 32 and are adapted to slide up and down in the base plate under the control of rotatable cardioid cams 36, 38 driven by means of shaft 40. In the spaces left between teeth 32 there are arranged shutter blades 14, only two of which are shown in Fig. 5, and each of which is clamped to the frame 10 in a nonlight-blocking position by means of its ends 16 (Fig. 2). On relative movement between plates 24, 26, the broad central portions of blades 14 become engaged by the rounded portions of teeth 32 and the narrow neck portions of the blades become twisted so that the blades occupy a light-blocking position. The complete cycle of shutter opening and closing may consist of a movement of the central portions of the blades through 90 degrees and back to their original positions, or if both sides of teeth 32 are rounded, of a single movement through 180 degrees.

Title: Impact-resistant rubbery graft polymers and blends
IPC: C08F279/04
Filed: 1960-02-15
Abstract: A dimensionally stable rubbery graft polymer is made by forming a resinous acrylonitrile polymer in the presence of a rubbery polymer of a minor amount of a vinyl aromatic monomer, e.g. styrene, a major amount of a conjugated diene monomer, e.g. butadiene, and acrylonitrile in an amount of 5 to 15 parts per 100 parts of total monomer used in the rubbery polymer.  The resinous polymer preferably comprises 60 to 80 parts of styrene and 40 to 20 parts of acrylonitrile.  The rubbery backbone polymer may contain a small quantity of a cross-linking monomer such as divinyl benzene.  The graft polymer may be made by first preparing the rubbery polymer in an aqueous emulsion system followed by the addition of the monomeric material which forms the resinous polymer.  The graft polymer products may be used in blends with other polymeric materials such as nitrile rubbers, polybutadiene, butadiene-styrene copolymers, polystyrene, styrene-acrylonitrile copolymers, polyvinyl chloride and polyacrylate esters.  In the examples the following blends are described:-(9-16) graft polymer +styrene-acrylonitrile copolymer+rubbery butadiene-acrylonitrile copolymer; (17) graft polymer+polyvinyl chloride+styrene-acrylonitrile copolymer+rubbery butadiene-acrylonitrile copolymer+a polyester resin plasticizer; and (22-27) graft polymer+styrene-acrylonitrile copolymer.

Title: Improvements in methods of and apparatus for producing shell moulds
Inventor: TAYLOR GEORGE WILLIAM
IPC: B22C23/00
Filed: 1953-02-26
Abstract: 748,085. Moulding-machines and processes. POLYGRAM CASTING CO., Ltd. April 24, 1953 [Feb. 26, 1953], No. 5432/53. Class 83 (1). In a method of making a shell mould, the two half moulds are placed together, with the shaped portions thereof in registration and with an adhesive between the mating portions, and pressure is exerted on the outer surfaces of the half moulds through the intermediary of a gas or a liquid until the adhesive has set. The apparatus comprises lower and upper casings 1, 2, Fig. 1, hinged together by a pin 3. A flexible diaphragm 7 of rubber is attached by its edges to the periphery of the lower casing 1 and a second diaphragm 8 is likewise attached to the periphery of the upper casing. Each of the casings is provided with an air port at each side. The port 20 to the lower casing communicates with an air supplypipe 21 and has a branch 22 leading to a conical seating 23 with which a connector-piece 26 in the upper casing engages to admit air to the upper casing through a port 25. Air may thus be admitted simultaneously to the spaces between the casings and diaphragms so that the halves of a shell mould, initially placed between the diaphragms in correct alignment, may be held until the adhesive used to join the halves is set. A handle 31, Fig. 3, connected to a campiece 27, is turned to lock the upper and lower casing-parts together. A spindle, also connected to the handle, operates through a cam to open a valve 33 to admit air to the device towards the end of the clamping movement. The handle is locked against movement, with the valve in the closed position, when the casing- parts are open. A plunger 41a enables the air to be exhausted when pressure on the mould halves has remained for a sufficient time. In an alternative method, air is evacuated from the flexible envelope within which the mould halves are contained and the latter are held together by atmospheric pressure until the adhesive is set. An adhesive of synthetic resin such as phenol-formaldehyde may be applied to one half mould and a hardener applied to the other half mould. Specification 674,421 is referred to.
