Patent GB-420976-A (GB)
Title: Improvements in connection with the moulding of bricks, tiles and the like
IPC: B28B11/16
Filed: 1933-06-07
Abstract: 420,976. Delivering and cutting bricks from extrusion machines. KNIGHT, A. E., Neacroft, Bransgore, Christchurch, Hampshire. June 7, 1933, No. 16317. [Class 87 (ii)] The column of clay from the extrusion die of a brick - making machine is cut up into lengths and transported to the drying-hacks without handling between these points. The column B emerging from the die A is received on wheeled trucks which are hooked together to form a continuous line and each have a flooring of spaced battens C. The movement of the column pushes the trucks along, a turned-up plate E forming an abutment for the column on the leading truck. As each truck is filled, the rear end of the column is cut through by a hand-operated wire (not shown), and the truck is then unhooked and transported on its two larger wheels to the cutting-apparatus shown in Fig. 2. Spaced wires T are then drawn down by hand against the action of the counterweights K to pass between the battens C and sever the column into individual bricks. The counterweights then restore the wires which return along the same path, leaving the truck free to be wheeled onwards to the drying-hacks. When a frontdelivering die is used, instead of a side-delivery die as shown, a roller table receives the column and carries it for such a distance as will allow the truck to be run in under it.

[Also in Group XI] Converting electric energy into motion of fluids by the action of magnetic fields.-Molten metal is discharged from a receptacle, e.g. a furnace or electrolytic cell, by causing it to rotate by means of a rotating magnetic field so that it rises at the sides due to centrifugal force and discharges at an outlet. As shown for a selfemptying furnace having a laminated core 1 with slot-windings 3 surrounding a crucible 7, rotation of the melt causes it to rise up and discharge at outlet 12. The core 1 carries a single-phase winding for melting the charge and additional polyphase windings for rotating it. A device for emptying furnaces is also described, in which the core has windings on its outer surface and is located inside a castiron tube with a delivery duct at the top, the metal rising up the annular space between the core and the tube.

Title: Improvements in fuses
IPC: F42C15/196
Filed: 1952-07-04
Abstract: 727,493. Projectile fuzes. VERWALTUNGSGES DER WERKZEUGMASCHINEN FABRIK OERLIKON. July 4, 1952 [July 7, 1951]. No. 16923/52. Class 9(1). Relates to ammunition projectile fuzes of the kind comprising a striker 2 which is displaced longitudinally by the action of centrifugal force on weights 4, a booster charge 14 at the rear end of the fuze casing 1, and an intermediate member 8 having a box carrying the detonator 12, this member being rotatable so that the box can be brought into line with the striker and the detonator in communication with the booster. According to the invention the striker normally locks the member 8 against rotation, and at the forward end of the fuze there is provided an element 16 which is melted by heat resulting from its passage through the air, this element serving to lock the striker against displacement until it has been melted during flight. In the construction shown the member 8 is of spherical form and has trunnions 11 which engage in slots 9a of a socket member 9. On firing, the inertia forces cause the striker to bear firmly upon the member 8, and the resulting friction between the latter and its seating opposes rotation of the member 8 to the armed position. When the element 16 melts the action of the weights 4 on surfaces 10a draws the striker forwards and thereby allows the member 8 to rotate to the armed position. The member is located in the armed position by a ball 13 which engages the rear edge of a second socket member 10. Detonation takes place on impact or when the centrifugal forces on the weights are insufficient to prevent the spring 6 from driving the striker against the detonator.
