Title: Improvements in and relating to the manufacture of articles from plastic sheets
IPC: B44C1/00
Filed: 1943-09-01
Abstract: 566,474. Printing on artificial resins. BRIGGS MANUFACTURING CO. Sept. 1, 1943, No. 14261. Convention date, Sept. 17, 1942, [Class 100 (ii)] [Also in Group V] Sheet material made partly or wholly of synthetic resin is printed with a design while the resin is in a partially cured condition and is then subjected to heat and pressure to complete the curing of the resin and to form a film of resin over the design. The sheet material may consist of a foundation layer 10, comprising about 40 per cent by volume of a thermo-setting resin and 60 per cent of a fibrous filler, and an upper layer 11 of the resin containing only about 30 per cent to 35 per cent of filler which is of finer texture than the fibres of the layer 10. The upper surface of the layer 11 is provided with a printed design while the resin is in a partially cured state, but sufficiently hard to receive the print. The combined sheet is then pressed between heated members 12, 13, which may be dies for forming the sheet into an instrument panel for a motor car. The heat and pressure causes a film 14 of liquid resin to form momentarily on the surface of the layer 11, submerging but not distorting the inked design, immediately after which the resin hardens to its final form. The surface of the die 12 may be etched to modify the appearance of the surface of the sheet, e.g. to represent pores if the design printed represents wood grain.

Title: Improved process and apparatus for manufacturing horse-shoe nails
IPC: B21G3/28
Filed: 1928-05-15
Abstract: 301,703. Wade, H., (Mustad & Son, 0.). May 15, 1928. Forging nails; dies.-In the manufacture of horseshoe nails by means of a four die press wherein the wire is fed to protrude in front of the press dies so that the material for the head is left on the end of the wire a strong spring acts on the feed lever positively to pull the wire oppositely to the feeding direction during the pressing operation. The wire a is fed through the press dies b, b<1> by the feed lever e pivoted at v and actuated by a cam h bearing against a roller e<1>. The lever carries a gripper f operated by a cam i, lever k, rod l, lever p, and spring q. During the first pressing operation, Fig. 2, the wire a is pulled to the right in the direction of the arrow y by the action of the spring g bearing on the feed lever. When the press dies move apart the wire is again moved to the right to bring the pyramidal neck m<1> of the head m closer into the dies so that on the second pressing operation, Fig. 4, the neck is brought to form m<2> and the shank n lengthened as at n<2>, the pull on the wire to the right being continued during this second pressing. For the formation of the nail point from the pyramid o by the die corners c<2> the wire is advanced in two stages for further pressing operations, Fig. 5, 6, during which a pushing action is exerted on the wire to form the point close to the crown of the next nail head. The wire is then moved forward and the finished nail severed by a hammer or cutting tool.

Abstract: 738,053. Coke-oven doors. KOPPERS GES., H. May 21, 1953 [May 29, 1952], No. 14378/53. Class 55 (1). In apparatus for handling coke-oven doors, a fluid pressure motor is connected through thrust means with the door-engaging and -lifting members, the said thrust means including means which may, in the event of failure of the fluid pressure motor, be operated mechanically or manually to lift the door. The reciprocating rod 21 of the fluid pressure motor is connected to the extension 23 of a sleeve 22, and is revoluble but fixed axially relatively thereto. The sleeve is internally threaded to screw on to the rod 18 which, through linkage, operates the door-lifting claws. The sleeve is externally splined to be driven by a worm wheel 26, but is slidable therein, so that manual or mechanical rotation of the wheel 26 by the worm 27 adjusts the effective length of combined push-pull rod assembly 18, 22, 21 to compensate for displacements of the door caused, e.g. by settlement of the ovens. This adjustment is effected whilst the apparatus is arranged for fluid-pressure operation, i.e. with an adjuster 34 which is threaded in an internal screw 39 in the casing 19, raised, as shown in Fig. 3, to give a clearance for the sliding motion of the sleeve 22 in the worm wheel 26. When the apparatus is arranged for mechanical or manual operation, the adjuster 34 is screwed down as shown in Fig. 2, to present a thrust ball race 35 to the top of the sleeve, the door lifting operation being then entirely effected by the sleeve 22 being screwed on and off the rod 18. Specification 699,399 is referred to.
