Title: Improvements in or relating to skiving or splitting machines
IPC: C14B1/20
Filed: 1933-03-07
Abstract: 416,352. Skiving-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., WOODCOCK, R. B., and BOOTHROYD, H., Union Works, Belgrave Road, Leicester. March 7, 1933, No. 6845. [Class 31 (i).] A skiving or splitting machine of the kind described in Specification 379,732 and comprising a rotary disced knife, a yielding feed roll 4, and an unyielding edge guide or presser 2, is provided with a single sliding cam 52 which, when actuated in either direction; will move the edge guide bodily towards or from the knife and also tilt it angularly, or the adjustments may be made independently. The treadle 96, Fig. 1, returned by a spring 104 operates a crank 84 engaging a pin 90 on the cam frame 52, Figs. 9 and 10, and the narrow part 54 of the cam is thus shifted to engage either of a pair of blocks 48, 50 on bell crank levers 40, 42 below the cam, and either of blocks 80, 82 on levers 76, 78 above the cam. The levers are mounted on axles 44, 46 secured in the swinging frame 6, Fig. 1. The lower levers control the up-and-down adjustment of the guide 2 and are connected to the part 12 carrying the guide 2 by blocks such as 36, adjustable screwed sleeves 32, 34, rods 24 with pin-joints 31 and T-heads sliding in a bar 18, an inclined slot 17, block 14, and pin 16. The upper levers 76, 78 control the angular adjustment of the guide 2 on the rounded edge 10 by similar connections to a bar 64 which engages a segment 60 by a block and slide 62. In operation, the cam 52 is slidden right or left, and the lever of each pair which has an end in the narrow part 54 of the cam is inactive ; the other levers are rotated by the inclines of the cam until engaged by the narrow part 54, thus operating the bars 18, 64. The angular movement of the yielding feed roll 4 relatively to the lower bevel face of the knife is varied by mounting the block 100, Fig. 4, in a member 103, the stem 105 of which is rotatable in a bracket 106 laterally adjustable on the machine. The block 100 is clamped by a screw 111, and the upward movement of the roll about the pivot 101 is limited by a bolt 112. The feed roll bearing and spring plunger adjustment 110 are described in Specification 24178/07, [Class 31]. Specification 23850/11, [Class 31 (i)], also is referred to.

Title: Submarine cable system
IPC: H04B1/58
Filed: 1931-03-05
Abstract: 374,131. Two - way transmission. PUTNAM, R. E. A., Mountain Lakes, New Jersey, and INTERNATIONAL COMMUNICATIONS LABORATORIES, Inc., 67, Broad Street, New York, both in U.S.A. March 5, 1931, No. 6847. [Class 40 (iv).] A submarine cable is forked, at a point remote from the shore, into two branches for transmitted and received signals respectively, the two branches being joined at the shore end by a delay network which passes a portion of the transmitted signals suitably attenuated and with reversed polarity into the receiving channel to balance the signals reflected into the receiving circuit at the cable junction. Telephone signals pass from the transmitter 1 through filter 3 and telegraph signals pass from 5 through filter 7, these two circuits uniting and joining the transmission lead 9. Some of the currents pass into delay network 14 and are reversed in polarity, phase, &c. so that they reach 13 at the same time as signals reflected at the cable junction 10 and as these signals balance one another the receiving apparatus 18, 19 are not affected. Received signals also branch at 10 and a portion of these passing via 9 and 14 create an echo at 13 but this is not disturbing if the cable junction is 100 nautical miles or so out at sea. If shorter shore end cables are provided the embodiment shown in Fig. 3 is provided in which one-way devices 38, 39 block the received signals from the delay network. The land and sea sections may be transformer coupled, separate windings being provided for feeding the cable and the delay network.

IPC: G08C13/02
Filed: 1926-03-12
Abstract: 250,552. Landis et Gyr Soc. Anon. April 9, 1925, [Convention date]. Counters actuated by electric and magnetic means.-A device for the distant transmission of the registration of one or more counting mechanisms, or electricity or other meters, comprises one or more relays and a continuous and intermittently rotated shaft which upon the energization of one of the relays actuates another shaft driving the distant counting mechanism. As shown applied to an electricity meter, the meter spindle 1, Fig. 2, through gearing 3, 5 drives a disc 6, Fig. 1, having a pin 7 co-operating with a tilting weight 8 adapted to close momentarily the contacts 10, 11, in the circuit of an electromagnet 15. The armature 16 of the electromagnet 15 is loosely mounted on a shaft 17 and carries a spring pawl 19 for actuating a ratchet wheel 18 secured to the shaft 17. The ratchet wheel 18 is advanced on the restoration of the armature to actuate, through a ratchet wheel 27, pawl 28 and gearing 29, 30, the pointer 32, Fig. 3, of the totals counter 31. Withdrawal of the armature 16 is effected by a projection 17<1> on a disc 21 loosely mounted on a shaft 20 driven through gearing 34 from a Ferraris motor 35, the disc 21 being resiliently coupled to the shaft 20 by means of a spring 25 and a pin 26 on the disc engaging a slot 23 in a disc 22 secured to the shaft. If the sum of the readings of the several meters is to be registered each meter has associated with it a unit comprising the parts 15, 16, 18, 19, 21, 22, 24, 25 mounted on the two shafts 17, 20 the respective discs 21 being so mounted that the projections 17<1> are in staggered relation to prevent simultaneous actuation of the shaft 17.

Title: Improvements in or relating to ion-getter pumps
IPC: H01J41/16
Filed: 1958-03-04
Abstract: 873,906. Ion-getter pumps. VAKUTRONIK VEB. March 4, 1958 [Oct. 12, 1957], No. 6982/58. Class 39(1). An ion-getter pump comprises an electrode consisting of high melting-point 'metal and arranged for being heated by foulean heat, means being provided for feeding getter metal intermittently or continuously in the form of powder or wire to a vaporizing surface of the said electrode for the evaporation of the getter metal, the said electrode being, at the same time, the cathode for the pump. The pump shown comprises a metal housing 1 closed at the lower end by a flange 2 and connected directly at the upper end to the container to be evacuated. A side connection 3 leads to a roughing pump which produces an initial vacuum of the order of 10<SP>-2</SP> mm. of mercury. Vaporization of the getter metal, e.g. titanium, is effected by a plate 5 forming part of a slotted cylinder 4 of sheet metal, e.g. tungsten or tantalum, which is connected to an alternating current heating supply. A resiliently suspended hopper 9 containing titanium powder 10 is vibrated by a hammer 8 carried on the armature 7 of an electro-magnet 6 connected to an alternating current supply. The powder drops through a funnel 11 and a baffle 12 on to the plate 5 and is vaporized to form a layer on the wall of the housing 1 which may be covered by a plate 13 to facilitate cleaning the housing and recovering the getter metal. The getter metal may alternatively be in the form of a wire which is fed to the vaporizer by a suitable mechanism. Electrons emitted by the cathode cylinder 4 are accelerated by a wire grid 15 e.g. of tungsten and are reflected by a plate 16, which is at approximately cathode potential, into an ionization space bounded by a grid 14 which is integral with the grid 15 and is maintained at a potential of 800 volts positive with respect to the cathode. The electron paths are lengthened by a magnetic field extending between iron pole shoes 17 and 18 energized by permanent magnets 19 and 20 which may be in the vacuum space as shown or outside. Alternatively the electron paths may be lengthened by employing a high-frequency voltage to produce oscillations. The electrons ionize any residual gas, the resulting ions passing through the grid 14 and being trapped on the plate 13. Pressures as low as 10<SP>-7</SP> to 10<SP>-8</SP> mm. of mercury may be reached provided the metal parts of the apparatus are cooled and that sealing means having a low vapour pressure are employed.
