Title: Improvements in and relating to typographic line-casting mechanism
IPC: B41B11/88
Filed: 1929-10-29
Abstract: 338,333. Cachemaille, H., (Intertype Corporation). Oct. 29, 1929. Metal pots and pumps. - In order to reduce the volume of air present in the injecting- throat of the metal-pot, a number of pumps are arranged horizontally in the pot with their discharge mouths located immediately above the normal level of the metal in the pot, and the pot is movably mounted above a stationary supply pot, from which metal is delivered at intervals to the casting-pot, so as to maintain a constant level therein. The upper or casting-pot 2, Fig. 3, is movably supported above the supply pot 1, Fig. 4, by parallel links 6. The supply pot is heated by a gas burner 10 or by electric heating-coils, and the casting-pot may be provided with heating-coils 17. The metal-injecting pumps are arranged side by side in the casting-pot, and each comprises a cylinder 19, fitting at one end into a mouthpiece 20, and resting at the other end on a curved seat 25 so that the cylinder can be readily removed. The cylinder is cut away at one end to permit of insertion and removal of the plunger 23. Each plunger is operated by a reciprocating bar 27, which is actuated by a lever 43 and a spfing 45 of adjustable tension, under the control of a cam 56. The bar 27 is normally held in retracted position by a latch 60, which is tripped by a block 59 on the cam 56, in order to allow the bar to be driven forwards by the spring 45. The casting-pot is moved up to the mould by cams, and is retracted by the pull of the springs 45, an additional positive withdrawing action being furnished by flanges on the cams. One or more of the casting- pumps may be locked out of action by means of hand-operated latches 65, according to the length of slug to be cast. Metal is supplied to the casting-pot from the supply pot 1 by a plunger 68 operated by a spring 76 under the control of a cam 69. The surplus metal returns to the pot 1 through an overflow pipe, the top of which is located slightly below level of the orifices of the casting-pumps, so that a minimum of air is contained in the mouthpieces. The casting- mechanism forms a self-contained unit, adapted to be coupled with a matrix-setting machine, or to cast from matrix lines composed by hand. Specification 14582/90 is referred to.

Title: Method and apparatus for the induction heating of billets and the like
IPC: H05B6/06
Filed: 1957-10-22
Abstract: 835,825. Forging; extruding. AJAX MAGNETHERMIC CORPORATION, [formerly MAGNETHERMIC CORPORATION]. Oct. 22, 1957 [Oct. 29, 1956], No. 32904/57. Drawings to Specification. Class 83 (4). [Also in Group XXXV] In order to evenly heat a thick metal billet (especially aluminium), in an induction furnace prior to forging or extruding, the furnace is automatically controlled (see Group XXXV) in two stages. In the first stage, full power is applied until the surface temperature of the billet reaches an upper limit (482‹ C.). This is higher than the temperature required for subsequent working, but not so high as to damage the billet. The surface temperature is then automatically maintained between this limit and a slightly lower temperature (474‹ C.) by intermittent energization of the furnace. This stage continues until the temperature difference between the centre and the surface of the billet falls to a first set value (28‹ C.) whereupon the datum setting of the automatic temperature control is shifted so as to maintain the surface temperature between a new top limit (465‹ C.) and the working temperature (460‹ C.). This second stage is terminated when the centre/ surface temperature difference falls to a second set value (3‹ C.). The billet is then automatically ejected from the furnace as soon as the intermittent heating allows the surface temperature to drop to the working value (460‹ C.). Specification 742,856 is referred to.

Title: Improvements relating to magnetos
IPC: H02K35/06
Filed: 1929-10-30
Abstract: 337,596. M-L Magneto Syndicate, Ltd., and Watson, E. A. Oct. 30, 1929. Inductor machines; reciprocating machines.- The magnetic circuit of a magneto comprises two parts in parallel, one part consisting of a permanent magnet, pole-pieces, and a movable armature, whilst the other consists of a member separated from the first part by one or more air gaps, windings being arranged on both parts, the arrangement being such that changes of flux occur in the second part when the armature is moved relatively to the pole-pieces. In the form shown, the pole-pieces b arranged at the end of the permanent magnet a carry coils f and co-operate with the armature c which is reciprocated between the position shown by the full and dotted lines in Fig. 1. The other part of the magnetic system comprises a core d which bears a primary winding g connected to the coils f in the manner indicated in Fig. 5 and a secondary winding h. When the armature is moved to increase the reluctance of the system, the contact breaker is opened as the armature approaches the end of its stroke and the current generated in the coils f during the armature stroke then passes to the winding g and thus induces the required voltage in the coil h. The breaker contacts i and m, Figs. 1 and 2, are separated by the engagement of a shoulder s on the plunger n, which is spring mounted in the stem p attached to the armature, with a shoulder q on the stem. An alternative type of contact breaker, Fig. 4, comprises a moving contact m, mounted on an auxiliary armature u, engaging with the fixed contact i. The armature u cooperates with auxiliary pole-pieces t which project from the main pole-pieces b. When the main armature c is in contact with the pole-pieces b the contacts are pressed together by the spring o, but when the armature is moved, the flux is diverted to the parts t, u which are attracted together, thus separating the contacts i and m. Instead of being reciprocated, the armature may be rotated; also, the winding f may be arranged on the armature instead of on the pole-pieces.

Title: Arrangements for controlling electric circuit breaker groups having two or more poles
IPC: H01H33/30
Filed: 1949-12-23
Abstract: 672,312. Fluid-blast circuit-breakers. AKT.- GES. BROWN, BOVERI, & CIE. Dec. 23, 1949. [Dec. 24, 1948] No. 33013/49. Class 38(v). In a gas-blast or other circuit-breaker wherein each pole is separately actuated by electrically remote-controlled valves b1... b3, the poles .are additionally coupled by a pneumatic system which ensures the opening of all poles, if one or more fails to open or close. The main valves b1 ... b3 each supply operating and arc-extinguishing gas, and are operated by control valves d1 ... d3 having operating solenoids p1 ... p3. Pipes f1 ... f3 connect the contact chambers a1 ... a3 or the contact sides of valves d1 ... d3 to a control apparatus g, which has three valves i1 ... i3 normally spring-biased to the upper position. If an opening order is given but the pole a, fails to open, the pressure in pipes f1, f2 keeps valves i1, i2, in their upper position but the gas moves valve f3 to its lower position, Fig. 3. Gas thus passes into pipe h and to pistons e1 ... e3 so as to open the control valve of the faulty pole. Gas also passes through a pipe n' to the left-hand side of a piston k1, and through an opening o to the right-hand side of a piston k11 so that an indicator m is moved to the "faulty" position F. When all the poles are open, the indicator is in position A, and when all are closed, it is in position E. A time element q in the pipe h delays the opening of the poles to allow for a single-phase fault causing the opening of one pole clearing on reclosure. One or more of the contacts of each pole may be hollow, and liquid may be used instead of gas. The supply of gas to valves i1 ... i3 may be controlled by valves located on the switch poles and controlled in dependence on the, contact position.

Title: Improvements in or relating to loud speaking telephone sets
IPC: H04B1/46
Filed: 1961-09-21
Abstract: 916,545. Loud-speaking telephones. WESTERN ELECTRIC CO. Inc. Sept. 21, 1961 [Oct. 4, 1960], No. 33785/61. Class 40 (4). In a loud-speaking telephone set in which the gains of the transmitting and receiving channels are differentially adjusted automatically in accordance with the energy propagating through the channels, the sensitivity of the differential switching device is controlled by the slowly varying ambient noise signal picked up by the transmitter. The Figure shows a loudspeaking telephone set comprising a transmitting channel 1 and a receiving channel 2 connected via a hybrid network 3 to a line 4. The transmitter channel includes a variable impedance device 9 comprising series diodes 12 and 13 which in the absence of D.C. bias current present a high loss to the transmitted signal while the receive channel includes a variable impedance device 23 comprising shunt diodes 28 to 31 which in the absence of D.C. bias present a low loss to the received signal, the two variable impedance networks being differentially switched to their opposite loss conditions by current from the control circuit. This control current is derived from the speech signal in the transmit channel which is conveyed to amplifier 41, via capacitor 50 and resistor 51, rectified at 42 then fed, via diode 45, to the two variable impedance circuits, the diodes of which are connected serially by connection 46. The level at which the switching takes place may be modified in accordance with the ambient noise level picked up by the transmitter microphone by passing the transmitter channel signal through circuit 52 which includes a rectifier circuit which charges capacitors 58 and 72, the charging circuit having a long charge time and a short discharge time, due to diode 59, which thus produces a potential which is dependent on the slowly varying ambient noise level around the transmitter microphone but largely independent of speech signals, this potential produces a current through diode 68 to lower its impedance, therefore a bigger transmitter signal is required to effect the change over from the receive to the transmit condition. A further rectifier circuit is connected to de-energize the control signal by passing a current derived from the received signal fed to the loud-speaker 21 through diode 68 to maintain the apparatus in the receive condition whilst a message is being received. Switch 70 is provided which connects capacitor 72 to a source of positive potential when the loud-speaking facility is not in use, the charge on this capacitor ensuring that the apparatus is not switched to its transmit condition by a high ambient noise level immediately the apparatus is switched on.
