Abstract: 1,078,573. Electro-erosion. TSENTRALJNAJA NAUCHNO - ISSLEDOVATELJSKAJA LABORATORIJA ELEKTRICHESKOI OBRABOTKI MATERIALOV. July 14, 1964, No. 15330/64. Heading B3V. [Also in Division G3] An electro-erosion apparatus has a templatecontrolled mechanism for effecting relative longitudinal and transverse movement of a continuously moving wire electrode 9 and workpiece 6. The wire electrode 9 is fed by pressure rollers 23, 24, Fig. 5 (not shown), from a feed spool 29 to a take-up spool 19. A braking torque is applied to the feed spool 29 by a twophase induction motor and the take-up spool 19 is driven through a friction clutch 21, Fig. 4 (not shown). The workpiece 6, which may be made of a carbide, is mounted on a longitudinally movable table within a liquid bath 10, Fig. 1 (not shown); the electrode assembly is carried by a transversely movable head 7, Fig. 1 (not shown). The longitudinal and transverse movements are produced by electric motors 142, 143, Fig. 7 (not shown), which transmit their drives through floating couplings 32, Fig. 6 (not shown). The motors are controlled by means 48, 49 which receive signals through relays 51, 52 from a measuring means 50. This in turn receives signals from automatic regulators 45, 46. Regulator 45 is responsive to conditions such as voltage, current or pulse frequency, in the spark gap between the electrode 9 and workpiece 6. Regulator 46 is responsive to similar conditions in a copying gap between the electrode 9 and a current carrying template 47 separated from the workpiece by insulation 112; a low voltage is applied to the copying gap between the template and the electrode. A plurality of workpieces 6, 267, 268, 269 may be eroded simultaneously by interconnected heads carrying wire electrodes 9, 264, 265, 266 controlled froma common template 47. Alternatively a plurality of similar profiles may be cut simultaneously from a single workpiece. The electrodes are supplied with spark pulses from individual high frequency generators 42, 270, 271, 272. An electrical control circuit is described.

Abstract: 151,335. Murray, R. L., and Telephone Manufacturing Co. June 18, 1919. Manual exchange systems and apparatus.-In a telephone system, particularly for connecting two or more divers' telephones to an exchange situated in a boat, the calling current trips a combined annunciator and relay which connects the calling party to the operator's telephone. A diver B calls the operator E by depressing the switch P with his chin. Current flows from the battery F via contacts B<6>, B<5>, and wires 2, 1, through the coil B<1>, thus tripping the lever B<3> and closing a speaking circuit between the telephones B, E, through contacts B<5>, B<7>, and wires 2, 3, in the manner shown at A. The operator cuts in any other diver bv manually operating the appropriate relay, and he can cut in all the divers at once by pressing the button H. The relay B', shown in detail in Fig. 2, is designed to prevent actuation when the boat rolls, and comprises an iron-clad pot magnet having a brass stem J which moves axially and bears a disk-shaped armature B<8> at one end and at the other end a latch B<4> which, on rising, trips the lever B', whereupon contact is broken at B<6> and made at B<7>, and a disk B<9> exposes an annunciator-disk. To re-set the device, a bellcrank B<12> is moved clockwise by the handle B", and to trip the device manually the bell-crank is moved in the opposite direction so that the arm B<13> engages the armature B<8>. The transmitter and receiver at each station are in parallel and have a common battery G in series with an impedance G<1>. According to the Provisional Specification, the bell-cranks B<12>, B<13> &c. may be replaced by pairs of finger-pushes which have respectively a pivotal and a sliding movement.

Title: Improvements in or relating to continuous rod cigarette-making machines
IPC: A24C5/18
Filed: 1958-05-15
Abstract: 895,733. Cigarette - making machines. USINES DECOUFLE. May 15, 1958 [Oct. 28, 1957], No. 15705/58. Class 130. [Also in Group XXVIII] Cut tobacco thrown by a picker 34, Fig. 1, past a rotating perforated cylinder 46 is caused by air passing into the cylinder to follow an arcuate path therearound at at least undiminished speed into a duct 53 where it is accelerated and carried to form a filler on the under-surface of a perforated nickel conveyer band 58 by an air stream passing therethrough to a suction chamber 59. The air movements are caused by low and high pressure fans 76, 80, Fig. 3, having suction conduits 75, 79, connected to the members 46, 59, and delivery conduits 61, 60, deflector grids 77, 81 and cyclones 78, 82, discharging to the conduit 79 and to atmosphere respectively, being provided to eliminate dust. The conduit 60 has a perforated exit flap 65 of expanded aluminium with orifices shaped to direct the air flow to the right. The conduit 61 has an exit 63. The air from both conduits passes through a perforated wall 67 adjustably covered by a pivoting shutter 69. Air and dust passing into the cylinder 46 move past stationary guides 47, 48 and out into three curved ducts 43 . . . 45, Fig. 2, leading in parallel to the conduit 75. Air passes upwardly between a guide 38 and a carded picker feed drum 31 to prevent shorts passing down therebetween. The drum 31 has a refuser roller 32 and comb 36 coating therewith. A scraper 56 removes tobacco from the cylinder 46. A receptacle 68 receives stem portions which are undeflected by the air movement. Vanes 73 and walls 74 of the duct 53 give the air stream a component of movement in the feed direction of the band 58 approximately equal to the band speed. The cylinder 46 so rotates that its surface presented to the tobacco moves therewith but at a faster speed. In Fig. 13 (not shown), the wall 67 is replaced by a conveyer band on to which the picked tobacco falls and which carries it into the range of action of the perforated cylinder 46, on the surface of which some of the tobacco may travel. The filler formed on the band 58 may be continuous but in Fig. 14 double-length filter plugs are taken by pushers 202 of a wheel 201 from a fluted drum 203 and transferred with the aid of a stripper 206 to the band 58 on which tobacco is subsequently deposited therebetween to form a composite filler. The Specification also describes the means disclosed in Specification 895,735 for transferring the tobacco on the band 58 to a continuous cigarette paper web. Specification 895,734 also is referred to.
