Filed: 1960-10-25
Abstract: 919,242. Slip couplings. ROTOR TOOL CO. Oct. 25, 1960 [Aug. 22, 1960], No. 36601/60. Class 80 (2). [Also in Group XXII] An impact clutch for a pneumatically operated power tool (e.g. a wrench, screwdriver &c.) comprises a hammer 36 keyed at 37 to a driving drum 31, an anvil 57 slidably carried by a drum member 51 and means for moving the anvil into and out of the path of the hammer. For low torque demand the drum 31 drives the anvil 57 through a pin 49 and spring cam ring 42, the cam surfaces 46 of which engages a complementary surface on a shifting bolt 58 slidably carried by the anvil. On increased torque demand the cam 42 moves radially inward the bolt 58 which acts on a pin 66 fast with the anvil 57 to move the latter inward, thus permitting relative rotation of the hammer 36. During its rotation the hammer 36 engages a cam 64 on the anvil to move the latter together with the bolt 58 into a position in which its impact face 60 is in the path of the hammer. Just prior to the hammer engaging the impact face 60 of the anvil, the spring cam 42 engages the bolt 58 and is energized so that after the impact the spring 42 can relieve the force between the hammer and anvil and move the bolt 58 and anvil 57 inward in readiness for another cycle. The clutch is operable in either direction, and the drum 31 is driven by a pneumatic motor 22 operable in either direction under the control of a valve 28.

Abstract: 814,489. Continuous-casting machines. MARVALAUD Inc. Nov. 30, 1956 [June 27, 1956 (2)], No. 36643/56. Class 83 (1). [Also in Group XXIX] Metallic filaments are produced by an extrusion nozzle comprising an annular retainer 17 with a tapering bore 23 in which seats a frustoconical plug 19 provided on its periphery with circumferentially-spaced grooves 25 tapering to narrow slots 27. The grooves and slots cooperate with the bore wall to provide feed chambers leading to extrusion orifices, and in order to avoid interaction of the emitted stream, the axes of the slots are very slightly inclined with respect to radial planes of the plug. A similar inclination may be given to the grooves. The retainer is fitted within the opening 13 of an ejector tube 9, which contains molten metal under pressure, and is surrounded by a lining 16. Alternatively the grooves and slots are located in the wall of the retainer. In a further modification, grooves and slots in the retainer wall co-operate with grooves and slots in the plug periphery. As shown in Figs. 6, 8 and 9, the plug comprises separate segments 321, and grooves 325 leading to slots 327 are formed in the vertical faces of some of the segments and co-operate with the faces of adjacent segments to provide feed-chambers leading to extrusion orifices. Opposed openings 341 in the retainer allow a wrench to rotate the nozzle as a unit. In a further embodiment, each of the opposed vertical faces of adjacent segments have cooperating grooves and slots. As shown in Fig. 10, streams of molten metal from each series of orifices impinge against a chill-block 37 on a line approximately radially thereof, to provide a variety of types of filament simultaneously. By rotating the nozzle through 90 degrees from the position shown, the filaments produced from the individual streams of each series will be of substantially the same character.

Title: Improvements in or relating to modulating and demodulating apparatus for use in duplex electric carrier systems
IPC: H04Q5/24
Filed: 1955-12-30
Abstract: 800,878. Carrier transmission; party line systems. GENERAL ELECTRIC CO., Ltd., HEAD, N. E., and INGRAM, D. G. W. Dec. 18, 1956 [Dec. 30, 1955], No. 37496/55. Class 40 (4). In a party line system in which at least one party utilizes a carrier channel for two - way communication, the channel terminating equipment includes a frequency changer which operates as a modulator for currents outgoing from the party and as a demodulator for those incoming. The filter system and frequency changer shown in Fig. 2 are for a substation employing the lower side-band produced by modulating a 6 kc/s. carrier with 0 to 2.5 kc/s. as its channel. Outgoing speech. Audio signals from the telephone set (not shown) are applied via the low-pass filter 14 (cut-off 2.5 kc/s.) and hybrid coil 16 to the ring modulator 22 which is fed with 6 ke/s. carrier by the transistor oscillator 24. The resulting two side-bands are amplified by the transistor amplifier 25, whereafter the low-pass filter 26 (cut-off 6 kc/s.) selects the lower side-band and applies it to the terminals 27 of the hybrid 16. Low-pass filter 14 rejects this side-band but the combination of high-pass filter 18 (cut-off 3.5 kc/s.) and low-pass filter 17 (cut-off 6 kc/s.) passes it to line. Incoming signals from line. These arrive at terminals 13 as the lower side-band (3.5 to 6 kc/s.) and pass via the hybrid 16 to the ring modulator 22, the resulting side-bands being amplified by 25 and the lower side-band being selected by 26 as before. This side-band (0 to 2.5 kc/s.), which is the required audio-frequency signal, is rejected by filter 18 but passes via lowpass filter 14 to the telephone set. As the hybrid is not balanced for frequencies above 6 kc/s., unwanted harmonics of the carrier frequency may appear across terminals 15, but the low-pass filter 17 prevents threse being passed to line. Transistor circuits. The transistors 28 and 29 are of point contact type supplied with - 40 volts and -1.5 volts over leads 30 and 31 respectively. The latter supply may be dispensed with if the amplifier 25 is modified to provide automatic bias for transistor 29. Alternatively, amplifier 25 may be replaced by a two-stage amplifier with, if desired, negative feedback. The circuits may be modified to use junction transistors. Power supply. In the arrangement shown, local power supply (not shown) is required for the microphone of the telephone set; but, by providing a suitable network in conjunction with filter 18, the central battery supply of the exchange may be utilized for the microphone and for the transistors.
