Title: Electro magnetic chucking device
IPC: B23Q3/154
Filed: 1920-07-07
Abstract: 147,141. Krupp Akt.-Ges., F. June 18,1919, [Convention date]. Electro-magnetic chucks.-An electro-magnetic chucking-device has an anti-flashing resistance B<7> in parallel with the magnetizing-coils A' and, by means of a switch b<3>, current may be so sent through the coils A<1> as to give a weakened holding-on flux or to annul the residual flux in the plate. The normal working position of the switch is on contacts b<5>, b<6> when current flows through conductors D, E to the coils A<1> and resistance B<7> in parallel, as shown by the arrows x. With the switch on contacts b<8>, b<9>, current flows through a conductor to the mid-point a<5> of the coils A<1>, where it divides and returns, as shown by arrows y, z, to a point b<10> and conductor J to the supply. As the point b<10> is not at the centre of the resistance B<7>, the current is greater than the current z and the residual flux due to the current x is destroyed. The point b<10> may be movable on the resistance to allow regulation of the demagnetizing-current or allow a weakened magnetizing current to be produced. The chuck is connected by a cable and plug to a separate switch, which is connected to the mains by a plug and socket.

Title: Improvements in or relating to driving gear for apparatus for casting stereotype plates
IPC: B41D3/00
Filed: 1926-08-06
Abstract: 256,958. Maschinenfabrih Augsburg- N³rnberg Akt.-Ges. Aug. 17, 1925, [Convention date]. Stereotype, casting. The shafts controlling the opening and closing of the mould and the metal valve in a stereotype casting-apparatus are carried by cranks oscillated from a main driving-shaft, the cranks acting on the controlling shafts by means of ratchet gearing. The main driving-shaft l, Fig. 1, is adapted to be connected to a motor by means of an operating-handle n, and to be disconnected automatically. A crank k on the shaft l is connected by links i, q to cranks g, p on shafts d, o controlling the movements of the mould and valve respectively. When the shaft l is rotated the parts g, i are moved from the positions shown in Figs. 1 and 2, which are their positions when the mould is open, to those shown in Fig. 3. A projection r on the crank g engages a shoulder s on a ratchet hub t fixed to the shaft d and so rotates the shaft to effect the closing of the mould. During the return movement of the crank g, a spring-pressed pawl h slides over the peripheries of the hub t and of a ratchet ring u loose on the shaft d until it reaches a recess w in the hub and engages a tooth 1 in the ring. The ring is thus rotated until the tooth 1 occupies the position previously occupied bv the tooth O. This action is continued until, after the sixth oscillation of the crank g, the tooth O on the ring u coincides with the shoulder C on the hub t. The pawl h then engages the shoulder C and turns the shaft d back into the position shown in Fig. 2, and so reopens the mould. At this point the shaft l is disconnected from the motor. When the shaft l and associated parts begin to move from the positions shown in Fig. 1, the crank p assumes the position shown in Fig. 6, wherein a shoulder A on a ratchet hub z, fast on the shaft o, and a tooth I on a ratchet ring a', loose on the shaft, coincide. As the crank moves into the position of Fig. 7, the arm b<1> of a two-armed pawl engages the shoulder and rotates the shaft o to open the valve. A tooth d<1> on the hub engages the pawl as the crank returns, and moves it into position wherein the arm c<1> is in position to engage the teeth in the ring a<1> when the arm reaches a recess e<1> in the hub. Continued oscillation of the crank finally brings the tooth 4 on the ring a<1> into the position occupied by the tooth O in Fig. 7 when the shoulder B on the ring and the 'tooth 1I on the hub coincide. On the next oscillation of the crank, the arm c<1> turns the shaft o and closes the valve. The two-armed pawl is again reversed by the tooth d<1>, and during the following two oscillations of the crank the ring is turned to bring the shoulder A and tooth I into coincidence again as in Fig. 6.

Abstract: 147,759. Latour, M. June 25, 1915, [Convention date]. Induction, preventing and minimizing; thermionic relays and repeaters.-Disturbance on telephone lines is reduced by connecting the microphone circuit to a thermionic relay the output circuit of which is connected to the line bv a transformer, and a large impedance is inserted in the line so as to reduce the disturbing currents whilst allowing the amplified microphonic voltage to maintain clearness of speech at the receiver. As shown in Fig. 2, the microphone circuit M<1> is coupled through a transformer B<1> to the grid circuit of the valve. The plate circuit comprises a battery 3 and a transformer primary coil T' coupled to the line L, in which are inserted the receivers E<1>, E<2> and impedances R<1>, R<2>. The Specification as open to inspection under Sect. 91 (3) (a) states that if it is desired to arrange the valves at a central station, the number of wires for each subscriber may be reduced by the arrangement shown in Fig. 3 (Cancelled), in which the receiver E is placed between the grid G and filament F, and the terminals of the line L are connected respectively to the grid G and filament F, the secondary of the transformer T being connected in the line. In another arrangement shown in Fig. 4 (Cancelled), the relay action is increased by arranging the plate circuit to react on the grid circuit through the coils T, T<1>. An intermediate point on the secondary coil in the line L is earthed, but the line L is not conductively connected to the valve circuits. In all forms, a condenser may be shunted across the coil in the plate circuit. Negative-resistance valves without grids may be employed. The filament circuit of the valve may be controlled by a switch which is closed only when the line L is connected up at the central station. The impedances R<1>, R<2> may comprise resistances, inductance coils, or capacities or combinations thereof. The output transformer of the valves preferably has a ratio greater than unity. The grid circuits of the valves may include a series or shunt capacity or a battery. This subjectmatter does not appear in the Specification as accepted.
