Abstract: 1245339 Super-conductors SIEMENS AG 3 Sept 1969 [4 Sept 1968] 43694/69 Headings H1A A5 and A4D A super-conductor comprises a layer of Nb 3 Sn containing C on a support. The layer is deposited on a strip-form support 12 in the apparatus shown by passing Cl 2  gas over heated sources 5 and 7 of Nb and Sn to produce NbCl 4  and SnCl 4  respectively which are mixed in tube 25 and reacted with H 2  entering through tube 17 at the surface of substrate 12 which is heated by passing an electric current through it. CCl 4  from source 22 is also added to the atmosphere surrounding substrate 12 to incorporate 0À25 to 1À3 wt per cent C in the deposited Nb 3 Sn layer. It is stated that the C may form a finely divided precipitate in the layer or may possibly form a NbC precipitate. The substrate may be a strip, wire or hollow cylinder of a metal alloy or may be quartz or ceramic. The C may also be introduced in the form of CO and the Nb and Sn chlorides may be replaced by the corresponding bromides or iodides. Gaseous HCl may be added to the H 2  flow to reduce deposition on the walls of the furnace. The C content increases the critical current (jc) of the layer and hence the H.jc product.

[Also in Division B8] Apparatus comprising conveyer means and transfer means which presents a stayed box and a gummed blank therefor to a wrapping-machine is made as a self-contained unit so that it can be used with a number of different wrapping machines. A gummed blank W has a box B placed thereon by hand or automatically at station S1, a conveyer 11 comprising a perforated belt on which the box assembly is held by suction carries the assembly to an intermediate station S2 and subsequently to a transfer station S3 where jaws 63, 64 hold the box assembly by suction and present it beyond the end of the belt to a position beneath the ram of the wrapping machine 16. The jaws 63, 64 are adjustable to accommodate boxes of various sizes. The machine 16 has a rotating shaft 43 carrying cams 44-47 which trip switches LS3 -LS6 in the electrical circuits controlling the various movements of the apparatus. To commence the cycle, an arm 230 drops on completion of the previous cycle and closes a switch LS1 (Fig. 1), a motor 42 on the wrapping machine is started and shaft 43 rotates and a clutch thereby operated by cam 45 so that a cam-shaft 15b (Fig. 13) rotates. A cam 15c on shaft 15b operates the wrapper feed means 15f via link 16e so that a wrapper is fed to a gumming roller 15a and on to the conveyer 11. Next, the cam 47 operates switch LS6 whereby a solenoid 129 causes a clutch 24-26 to connect crank mechanism 21-23 (Fig. 3) to a motor 17 whereby the jaws 63, 64 are returned from beneath the wrapping machine ram to grip the box assembly. Rotation of shaft 20 on which the crank mechanism is mounted also causes a cam 34 to rotate and lower stops 40a behind an advanced box. The crank mechanism is then de-clutched. A peg 25a now operates a switch LS2 whereby an air valve is changed over and suction applied to the jaws 63, 64. Cam 45 again trips switch LS4 on next operation of the wrapping machine to commence another cycle and also to re-engage clutch 24-26 whereby the crank mechanism makes the second half of its revolution and the jaws 63, 64 present the box assembly beneath the wrapping machine. A dwell occurs while the wrapping machine operates. A foot pedal may control starting of the wrapping machine or control the conveyer and transfer apparatus.

Title: Improvement to Control Devices for Direct-Viewing Memory Tubes
IPC: G11C11/23
Filed: 1967-09-28
Abstract: 1,191,292. Cathode-ray tube circuits. THOMSON-CSF. 28 Sept., 1967 [4 Oct., 1966], No. 44313/67. Heading H4T. In an arrangement for controlling the potential of the storage electrode of a direct-viewing storage tube of the kind utilizing a writing beam and a holding beam by the application of erasing pulses to the storage electrode the duration of such pulses is made dependent on the state of the electrode. As shown in Fig. 2, the state, i.e. the potential, of the storage electrode 41 is derived as an amplitude modulation of a 20 kc/s. carrier signal supplied from source 6 to the holding gun 30, 31 (formed as four parallel connected elementary guns). The amplitude modulated signal is fed via an amplifier 10 to a synchronous detector 11 the output of which is filtered in 12 to provide a D.C. signal voltage for amplification by a differential amplifier 15 supplied with an adjustable reference voltage input 150. The output from 15 is then utilized as a trigger for the erasing pulse generator 16 which produces a pulse having a duration proportional to the amplitude of the input trigger from amplifier 15. The erasing pulses at output 161 of generator 16 are supplied to the storage electrode 41 via switch 92 which together with ganged switches 91 and 93 are changed over from the positions shown by means of an operating device 9 controlled by pulses from output 160 of generator 16. The switching arrangement, which may in practice comprise equivalent electronic means, operates, in addition to connecting the erasing pulses to electrode 41 via contact 92, to short-circuit the input to amplifier 10 via contact 91 and to remove the H.V. supply 13 from the luminescent screen 40 via contact 93. The synchronous detector and filter may be replaced by an amplitude detector. A signal indicative of the state of the storage electrode may be derived from the collector grid or from the supplementary grid (Fig. 1, not shown) instead of from the storage electrode itself.

Abstract: 1,188,746. Nut-runners; screwdrivers. GARDNER-DENVER CO. 23 Sept., 1968 [16 May, 1968], No. 45176/68. Heading B3N. [Also in Division F2] A fluid-operated nut-runner or screwdriver has a motor 18, connected to a drive spindle 50 and an exhaust fluid passage consisting of annular areas 96 and 110, conduits 102 and space 104 leading to a head portion (not shown), and thence to the exterior of the tool, the tool comprises a unitary clutch and valve between the motor and the spindle 50, which is operable in response to a predetermined torque to disengage the motor from the spindle, and shut off the flow of fluid in the passage. Operation is by a rotor shaft 20 driving a clutch hub 28, which has an annular member 34 press-fitted on to it, this member 34 has dental teeth 36 which drive a member 42 via teeth (44), Fig. 2 (not shown), member 42 being keyed by ball keys 48 to the driver's spindle 50. Teeth 36 and (44) are designed such that they force themselves apart. Opposing this force is a biasing spring 64 and a torque control mechanism which comprises a cylindrical race 56, having a bevelled circumferential groove 70, in which balls 72 are retained by springs 76. As the torque required increases, the axial force increases, until the balls 72 are forced up sloping walls 92 of the groove 70 thus allowing axial movement of member 42 and disengagement of the teeth 36 and (44). A plate 106 is attached to the member 42, which moves axially until the plate engages a surface 98, thus closing the exhaust passage, and thereby choking off the motor fluid flow. The position of member 42 is maintained by fluid pressure build up in area 96 until when the supply of fluid to the motor is stopped, the fluid in area 96 bleeds out through a passage 116 relieving the pressure as surface 114 and allowing the bias spring 64 to force the teeth 36 and (44) into re-engagement. A ring 78 has spiral cam surfaces 80 whereby the torque necessary for disengagement of the drive can be varied. The ring 78 is retained in a given position by a spring 84 biased into a groove 86.

Abstract: <PICT:1023698/C6-C7/1> In the continuous production of potable spirits, alcoholic liquids or mashes obtained by fermentation of fruits containing sugar or starch are vaporized, the resulting vapour is passed upwardly through a fractionating column having at least three means for discharging different fractions and a first fraction having a high alcohol content is combined with a second fraction having a low alcohol content, these two fractions being removed from the fractionating column through first and second discharges respectively above and below an intermediate third discharge. Referring to the drawing, vapours from which the alcohol is to be removed are supplied through pipe 1 and enter into fractionating column 2.  The distillate forming at a distillation attachment 3 is cooled by a condenser 4 and collected in a vessel 5; this distillate forms the main quantity of the recovered product and is blended with the product of low alcohol content withdrawn from the bottom end 6 of the column.  The fraction containing fusel oil is removed at an intermediate point 9 through a line 10, while a distillate containing undesirable constituents forming at distillation attachment 11 is discharged into an auxiliary collecting vessel 14 and thus is excluded from the final product. Substances condensing in the upper part of the column may be added to the product in vessel 5 or discharged to the auxiliary collecting vessel 14.  The apparatus should be made of glass or ceramic material to avoid spoiling the taste of the final product caused by metal corrosion.
