Title: Improvements in or relating to gaseous electric discharge devices and circuits including such devices
IPC: H03K29/00
Filed: 1950-12-15
Abstract: 738,792. Digital electric counting apparatus. WESTERN ELECTRIC CO., Inc. Dec. 15, 1950 [Dec. 15, 1949], No. 14472/53. Divided out of 738,732. Class 106 (1). [Also in Group XL (a)] A counting arrangement comprises a gaseous discharge device having a plurality of cathodes mounted in an array comprising rows extending in two or three co-ordinate dimensions, an anode opposite said cathodes, and means for stepping a discharge selectively from any cathode to a next adjacent one in any of said dimensions. The stepping may be obtained by the use of auxiliary electrodes of lower efficiency than the cathodes, as described in Specification 738,732, in which case the discharge can be stepped in each direction in each of the dimensions, or if stepping in only one direction in each of the dimensions is required, the stepping may be obtained by the use of auxiliary cathodes which together with the main cathodes are formed with portions of different efficiencies as described in Specification 708,424. The arrangement shown comprises a tube of the latter type (see Group XL (a)) in which each main cathode 11 has a U-shaped body portion and two tabs, and each auxiliary cathode 12 has a U-shaped body portion and a single tab. The tabs function as discharge initiating or directing elements, and are analagous in their performance to the auxiliary electrodes described in Specification 738,732. The main cathodes 10‹ to 11‹ are connected in common to a lead A, the auxiliary cathodes 12<SP>1</SP> extending in one dimension are connected to a common bias VMB, and the auxiliary cathodes 12<SP>2</SP> are connected to a second common bias HMB. The main cathodes are biased negative relative to the auxiliary cathodes by a source 17 and the anode 160 is biased positive relative to all the cathodes by a source 19. Individual pulse sources 18x and 18y are provided for the two groups of auxiliary cathodes, each effective to drive the respective group of auxiliary cathodes negative with respect to the main cathodes. A three-dimensional arrangement is obtained by providing a third tab on the main cathodes and providing additional main cathodes and an additional group of auxiliary cathodes which are connected to a third common bias.

Title: Device for use in phase separation in liquid-liquid extraction
IPC: B04B5/06
Filed: 1972-03-28
Abstract: 1345679 Centrifuge container; determination of partition coefficients KERNFORSCHUNGSANLAGE JULICH GmbH 28 March 1972 [29 March 1971] 14553/72 Headings B1X and B2P [Also in Division B8] A liquid phase separation device for use in a centrifuge comprises a container I having an opening to provide access to its interior, a locating member II which can be fitted to the opening, a tube III carried by the member II and arranged to have one of its ends adjacent, but spaced from, an inner surface of the container remote from said opening when the member II is assembled to the container I, and a closure IV for that one end of the tube, the closure being displaceable by centrifugal force to open said one end of the tube to allow liquid to enter, and be extracted through, the tube. The locating member II is in the form of a stopper having an air vent V and a central bore in which the tube III is located. The container, the stopper and the tube may be made of polyethylene and the closure or plug IV of PTFE. In a liquid-liquid extraction operation, the liquid phases are mixed by manually shaking, or by using a vibrator to vibrate, the container I containing the phases. The container is then placed in a centrifuge to separate the phases A and B. An aliquot part of the lighter phase is extracted by means of a pipette and quantitatively analysed. The container is then closed by the stopper II through which extends the tube III closed at one end by the plug IV which prevents the lighter phase entering the tube as the latter is moved through the lighter phase into the heavier phase B. A second centrifugal operation is carried out causing the plug IV to be forced out of the tube III so that the heavier phase can enter the tube from which an aliquot part can be extracted by a pipette for analysis. The device may be used for determining partition coefficients for a mixture of strontium and yttrium isotopes using a solution of hydrochloric or nitric acid as one phase with various mixtures of carbon tetrachloride and methylisobutylketone as the other phase.

Title: Apparatus for automatically delivering an orderly sequence of workpieces
Inventor: MYNARD LEONARD MAURICE
IPC: F27D3/00
Filed: 1960-01-23
Abstract: 920,561. Feeding billets to furnaces. MANSILL, BOOTH & CO. Ltd. April 24, 1961 [Jan. 23, 1960], No. 14656/61. Divided out of 902,428. Class 51 (2). [Also in Group XXX] Billet-type workpieces 1 urged along a guide track 2 are either held against further movement by a piston 6 as shown, or the leading piece 1 is transferred by the piston 6 on to a conveyer 4. The latter conveys the pieces 1 through a furnace (not shown) and a time delay mechanism is provided so as to maintain the movement of the conveyer at the end of a working shift until the furnace was sufficiently cooled. The piston is operated by air pressure from a conduit 17 and controlled by a two-way change-over valve 16. The latter is operated by impulses received from a solenoid-controlled valve 14, itself controlled by a micro-switch 13 actuated by projections 11 on a drum 10 geared to the conveyer drive roller 5. Thus the pieces 1 are transferred by piston 6 at a frequency proportional to the conveyer speed. A pin 18 carried by the drum 10 acts on pins 19 carried by a screw 21 so as intermittently to rotate the latter. A nut 24 on the screw 21 during normal working, is set at the right-hand end of the screw 21 and is thus free from engagement with a bar 26 and is free to turn, and is not constrained to move axially. A bar 26 can be swung about a pivot 26a on the mounting 23 of the screw 21. At the end of a shift when the furnace is cooling, the nut 24 is set to the lefthand end of the screw 21, a slot 25 of the nut 24 engaging a downwardly projecting portion of the bar 26 so that the nut 24 is constrained to move axially to the right. When it reaches the right-hand end of the projecting portion of bar 26, sufficient time delay has elapsed to prevent pieces being damaged in the furnace. The nut thus operates a microswitch 28 to stop the conveyer drive.

Abstract: 1,046,431. Making bag tubes. WALTER DURBECK PAPIERSACKFABRIKEN G.m.b.H. April 17, 1963, No. 15173/63. Addition to 1,031,756. Heading F2P. The apparatus differs from that of the invention of the parent Specification in that, in the first embodiment, the spaced parallel guide plates, instead of merely diverging in a longitudinal direction, are disposed, Fig. 1, so that the longitudinal axes of the spaced plates 100, 101, Fig. 1, intersect as seen in plan view with the result that, as the tubular web is drawn over and along the spaced plates it is turned about its longitudinal axis through half the width of its lateral portions, as in the parent method, but, instead of leaving the output end of the plates with inwardly creased gussets, inward folds that are made by rollers 104, at the place where the axes of the plates appear, in plan, to intersect, are only temporary for the sole purpose of tensioning the web and disappear as the tubular web advances beyond the point of intersection. Printed matter 103 which, before the tubular web passes through the apparatus is wholly on the top or bottom flat side of the tube, as shown dotted in Fig. 4, is spread, after passage through the apparatus, equally on both sides of the folds (Fig. 8, not shown). Instead of tensioning the web by pressing in the sides at the middle of its passage through the apparatus by the rollers 104, the plate supporting member, or bearer, 108 may have a longitudinal section (Fig. 3, not shown) so that the plates are not in parallel planes but diverge to a maximum spacing at the place of intersection, the increase in spacing resulting in the web being held taut. In the second embodiment, the tubular web is passed between a pair of rollers inclined to the horizontal and then over a wire spreader device, Fig. 10, as in the second embodiment of the parent invention, but instead of them passing through a folding and gusseting device the web is reflattened by rollers 111 and spread by discs 112 (Fig. 15, not shown). The angle of inclination of the initial pair of rollers is adjustable by a screw and crank handle. Instead of passing the web through an initial pair of rollers, the second embodiment may be modified by making the axle 113 of the reel of the supply roll 114 tiltable (Fig. 17, not shown), the angle being adjusted by a crank 126 which operates a worm and worm-wheel to rotate the mounting 115 of the reel, with its guide roller 116. Air under pressure may be used to inflate the tubular web and so spread it.
