Title: Extruded sheet material and apparatus and method for making same
IPC: B29C48/08
Filed: 1964-04-29
Abstract: 996,432. Extruding coloured thermoplastic sheets. ROWLAND PRODUCTS Inc. April 29, 1964 [May 13, 1963], No. 17706/64. Heading B5A. Synthetic thermoplastic sheet material having a differentially coloured band therein is made by injecting into a main stream of the material a smaller second stream of differentially coloured material whilst reciprocating the discharge portion of the injection means transversely of said main stream to provide a composite stream having the second stream encased therein, and extruding said composite stream to form the sheet containing a longitudinally extending differentially coloured band with a transverse directional component. Differentially coloured materials include those of different colour or lacking in colour, or of different optical properties. The process may be used for manufacturing cellulose acetate or cellulose acetate-butyrate sheets incorporating dyes or pigments for use in making two-toned spectacle frames. The main thermoplastic material is fed by worm 46 from hopper 50 through conduit 40 in which it is plasticized by heaters 39, to the die block assembly 22. The secondary coloured thermoplastic material is similarly fed from hopper 70 to the die block assembly 22 to be extruded as the undulating coloured stream 6 encased in the main sheet 2. The die block assembly 22 has a cylindrical chamber 30 communicating with die orifice 32 and via duct 38 with the mainstream thermoplastic conduit 40. Located coaxially within the chamber 30 so that the main stream thermoplastic material may flow all round it is the hollow cylindrical inner portion 74 of the conduit for the colouring material, having a longitudinal T-shaped slot to allow communication between its interior and the die orifice 92. In this T slot is mounted a slider nozzle 94 which is reciprocatably driven by crank unit 112 and motor 114 to vary the position of injection of the colouring material into the main stream to produce an undulating coloured band within the mainstream of thermoplastic material. In various embodiments, different shaped aperture nozzles may be used to provide a variety of undulating patterns.

Title: Improvement in the Process of Casting Pottery and other like Articles.
Inventor: ALLEN BERNARD JAMES
IPC: B28B1/26
Filed: 1916-12-11
Abstract: 110,649. Allen, B. J., and Ames, R. Y. Dec. 11, 1916. Moulds; processes.-Relates to the casting of articles from slip mixtures in plaster, porous pottery, or other absorbent moulds and consists in applying a vacuum to augment deposition. The moulds may be encased wholly or partly by a vacuum jacket. For small articles such as insulators, the mould is formed of porous pottery with the outer face glazed to form the vacuum chamber. In the production of articles of varying thickness, the thickness is exaggerated and coned deposition by saturating thin parts with water or by applying to the thick parts perforated or porous vessels filled with calcium chloride conveniently mixed with asbestos; or the mould a may be surrounded by a cast-iron jacket e in which it is supported by studs g so arranged as to facilitate exhaustion from the thick parts of the article and to retard it from the thin parts. Where it is necessary to remove superfluous slip, air is admitted to the vacuum chamber during such removal. For articles such as plumbago crucibles or fireclay glass-house pots, outside and inside moulds are used, the inside mould being removed immediately the cast material is sufficiently hard. To prevent bursting, the moulds may be strengthened with steel bars and wire or expanded metal and the mould parts clamped together by metal bands fitted with tension screws.

Patent GB-847727-A (GB)
Title: Motor-driven constant-force support hangers
IPC: F16L3/215
Filed: 1958-06-06
Abstract: 847,727. Automatic tension control systems. GRINNELL CORPORATION. June 6, 1958 [June 12, 1957], No. 18102/58. Class 38 (4). A constant force support hanger comprises a supported member 43 to which a load, e.g. a pipe line 10, is applied, anchor means 13 for supporting the member, means for adjusting the effective length of the hanger between the load and anchor means comprising means for converting rotary motion to straight line motion, means for actuating the length-adjusting means by providing the former with the said rotary motion, means responsive to changes in force applied to the member 43 by the load for actuating the actuating means to adjust the effective length of the hanger between the load and the anchor means to compensate for the said changes in force, and means associated with and forming part of the hanger for neutralizing and retaining within the hanger rotary force in excess of that which is converted into straight line motion whereby substantially no rotary force is transmitted externally of the hanger. As shown in Fig. 1, the hanger comprises a hollow, cylindrical frame 12 carrying on an intermediate wall 14 thereof an electric motor 16 the drive shaft 18 of which is horizontal and carries a worm-gear 20 meshing with a wormwheel 22 secured to a vertically disposed screw member 26 receiving a nut member 36 provided with depending arms 38. Secured to the latter is a rod 42 connected to a rod 43 through a motor switch and switch control mechanism 45, the mechanism allowing the rod 43 to move vertically with respect to the rod 42 with vertical movement of the pipe-line. Extending radially from the member 26 is an arm 46 carrying a roller 48 lying in a slot 50 in the frame. Movement of the pipe-line upwardly or downwardly changes the force exerted by the pipe-line on the hanger and results in relative movement of the rods 42, 43 and the mechanism 45 is actuated to supply electrical power to the motor 16 to drive the latter in one direction when the force is decreased and in the opposite direction when the force is increased. Rotation of the worm-wheel 22 rotates the member 26 and the non-rotatable nut 36 moves up or down to compensate for decrease or increase in force exerted by the pipe-line. Rotation of the member 36 is prevented by the roller 48 engaging the sides of slot 50. Alternatively, the arm 46 engages a rod forming part of the frame, or a rod extends into an aperture in the nut so that the nut is free to move vertically with relation to the rod. In modifications (a), the screw member is threadedly received in the worm-wheel and is movable vertically; (b) two screw members 122, 124, Fig. 7, journalled in the frame 106 and geared to rotate in opposite directions, are used to actuate a single nut member 139; and (c) two screw members movable vertically with respect to the frame are connected by a cross-piece adapted to carry the pipe-line. Specification 534,940 is referred to.

Title: Carriage-feed mechanism for typewriters
IPC: B41J19/48
Filed: 1936-07-03
Abstract: 465,016. Typewriters. DEUTSCH, R. July 3, 1936, No. 18552. Convention date, July 5, 1935. [Class 100 (iv)] Letter-spacing mechanism.-In a carriage feed mechanism for typewriters of the kind in which two or more rigidly interconnected detents co-operate with the feed rack of the platen carriage and are arranged side by side in the direction of motion of the platen, preferably at both sides of the point where the types strike the platen, the distance between the detents is at least of a length corresponding to the difference between the length of carriage feed and the length of the feed rack. The escapement mechanism comprises a bar 4, Fig. 3, pivoted at 11 to the machine frame and provided with teeth 3 to engage the rack 2, and a bar 6 slidably mounted by means of pins 8 and holes 7 on the bar 4 and provided with teeth 5. The length of the holes 7 is equal to the pitch of the teeth on the rack 2 plus the diameter of the pins 8. The bar 6 is biassed to the right by springs 18. The teeth 3, 5 are separated by a vertical distance less than the depth of the rack 2, so that one pair is always engaged with the rack. The rack 2 is drawn to the left by a spring and is normally engaged with the teeth 5. When the bars 4, 6 are rocked by the co-operation of a key lever with a universal bar mounted on forward extensions 9 of the bar 4, the teeth 3 engage the rack, and the bar 6 is freed to be drawn to the right by the springs 18. On release of the key the teeth 5 re-engage the rack and permit it to advance by one tooth. A slotted carriagerelease lever engages a pin 15 on the bar 6, and draws it forward for carriage release. It is returned by the springs 18. The extreme limits of the carriage movement are represented by the engagement of the space 25 on the rack with the left-hand tooth 5, and of the space 26 with right-hand tooth 5. The further the teeth 5 are spaced apart the longer can be the platen for a, given length of rack 2. Back-spacing mechanism.--Back - spacing mechanism comprises a bar 30, Fig. 7, provided with teeth 31 and slidably mounted on the machine frame 12 by means of pins 34, 35 and holes 32, 33.
