Title: Improved Means for Reducing the Reflex Action at the Points of Connection of Electrical Conductors or Circuits Differing in the Values of their Electrical Properties.
Filed: 1906-04-19
Granted: 1906-08-09
Abstract: 9273. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. April 19. Telephone systems. - In transformer apparatus employed, as in telephone systems, at the points of connexion of alternating-current circuits of different electrical properties, arrangements are made to allow the passage of continuous current between the circuits while preventing its passage from one side to the other of the same circuit, one side of each circuit being in metallic connexion through a part of the transformer or auto-transformer coils with the corresponding side of the other circuit, while the condensers, polarization cells or the like are inserted between the parts of the transformer windings. In Fig. 1, each half a of the divided transformer in one circuit is connected by a wire to each respective half b of the transformer in the other circuit, and a condenser separates the halves. Fig. 2 shows an analogous arrangement with an auto-transformer. In Fig. 3, separate condensers c, c are employed, and the connexions are made through choking-coils d, d. In the arrangement of Fig. 4, applicable to a central battery telephone installation, the connexions are made through the battery on one side and a plain wire on the other. The transformers may have separate or common cores, forming open or closed magnetic circuits, or they may be coreless.

Title: Improvements in or relating to Type-casting Machines.
Inventor: BOULT ALFRED JULIUS
Filed: 1906-08-14
Granted: 1907-05-02
Abstract: 18,231. Boult, A. J., [Lanston Monotype Machine Co.]. Aug. 14. Type; type, setting &c.-A device for casting low quads or spaces in monotype machines by means of a divided mould blade is shown applied to the machine described in Specification No. 8633, A.D. 1899. The device is actuated by the matrixclamping mechanism and serves to close the mould should a matrix be imperfectly centred. Part of the device may serve to reinforce the centring- plunger spring when a larger mould is required, as in casting sorts. The mould blade comprises a lower or main section 2, Fig. 14, and an upper section 3, Fig. 13. The blade is actuated by the usual cross-pin, which passes through an opening 22 in the lower blade and through a recess 23 in the upper blade. A projection 18 on the upper blade enters an opening 19 in the lower blade, and a fixed stop 20 passes through the opening 19 and through an opening 21 in the upper blade. The projection 18 co-operates with the stop 20, to aline the casting-faces of the blades when the lower blade advances to eject the space. The stop 20 is vertically adjustable to enable it to form a top guide for the blades. Pivoted to the upper blade is a latch 24 having a bevelled shoulder 25. A spring 29 holds the shoulder 25 against a bevelled face 26 on the lower blade and locks the blades together. The upper blade is advanced independently of the lower blade by a lever 39 which engages an arm 27 on the latch 24. The latch is first rocked to disconnect the two blades, and then further motion of the lever 39 advances the blade to close the top of the mould. When the lower blade advances to eject the space, the latch reengages it and the two blades return together. The matrix-centring plunger 8 is actuated by a lever 9 through a spring 12 located between two heads 29, 30. To the heads 29, 30 are pivoted, respectively, pairs of levers 31, 32 which are connected by links 34. The levers 31 are pivoted to a cross-head 35 connected by a rod 41 with a lever 40, which acts on the lever 39 and advances the upper mould blade. The levers 32 are connected by links 37 with a cross-head 36 which is supported by a spring 38. When the relative motion of the heads 29, 30 exceeds a certain amount, owing to premature arrest of the centring- plunger 8, the cross-head 35 rises and causes the lever 39 to advance the upper mould blade. This effect may be obtained by the use of matrix blocks having centring-cavities of less than normal depth. The same result is produced if a matrix is imperfectly centred and the plunger 8 engages the die-case. To throw the device out of action, the cross-head 36 is depressed against its spring and is there held by shoulders 49 on a rotatable stopplate 48. The cross-head 35 is thereby depressed and the lever 40 moved away from the lever 39. When a larger mould is employed, as in casting sorts, the spring 38 is caused to reinforce the spring 12. To effect this, a recessed head 47 is rotated so that shoulders thereon prevent the rise of the cross-head 35.

Abstract: 29,109. Mocomble, C. C. de. Dec. 23, 1905, [date applied for under Patents Act, 1901]. Railways for recreation.-Moving platforms running upon electrically-actuated friction rollers as described in Specification No. 9258, A.D. 1899 [Abridgment Class Railway &c. vehicles], are provided with electric circuits which connect up the motor as a braking-generator in circuit with an adjustable resistance and the solenoid of an electro-magnetic skid brake whenever any section meets an obstruction. Under normal circumstances, the motor is connected across the mains by a switch I<1>, held closed by a solenoid S' in a circuit 2<1>. The circuit 2<1> has a switch P which is opened should the circuit 3<1> of a solenoid S<2> regulating this switch be earthed. A spring r<1> then throws over the switch I<1>, and the motor is connected up as a braking-generator with the circuit 4<1> containing the solenoid R of the electro-magnet E and the resistance R'. The circuit 3<1> is in connexion with a lead 3<2> which passes through articulated frames such as m, n, o, p, Fig. 11, mounted on the platforms and connected to earth. The frames m, n, o, p are adjusted to allow a certain play to the vehicles, but should this be exceeded the frames contact with the lead 3<2> and the circuit 3<1> is completed. As described in the prior Specification, the friction driving-wheels 1, Fig. 6, supporting the platforms are carried by a frame 4 mounted at one end on a pivot 9 and supported at the other upon a leaf spring suspended by links from the main framework. The pole shoes 2 of the electro-magnet E, which act as a skid upon the platform during braking, are slidably mounted upon a standard 3 carried on the frame 4 and are linked by rods 8 either to a pin 10 on the main framework or to the pivot 9. In a modification, Fig. 10, the rods 8 are connected by a link 12 to a leaf spring 13 on the main frame. The portion of the standard 3 upon which the electro-magnet rests is inclined in such a manner that, underthe control of the rod 8, the pole shoes 2 are always maintained the same distance from the platform. The braking effect is increased by the friction between the platform and its supporting-rollers.
