Abstract: 449,550. Obtaining high vacua. M-O VALVE CO., Ltd., Electra House, Victoria Embankment, London, and WRIGHT, D. A., c/o General Electric Co., Ltd., Wembley, Middlesex. Dec. 28, 1934, No. 37216. [Class 8 (i)] [See also Group XL] A method of removing residual gases from an evacuated sealed vessel by the provision within it of a surface (not a cathode) coated with an alkaline earth oxide, comprises the step of heating the surface during the evacuation to a temperature of at least 1000‹ C. whereby a coating on the surface, if not already consisting of alkaline earth oxide, is converted into alkaline earth oxide. The oxide is preferably calcium oxide, but barium or strontium oxides or mixtures of these may be used. In an example, a thermionic valve is provided with a nickel gettering disc, 1-2 sq. cms. in area, coated with alkaline earth carbonate; an annulus or short cylinder bent from strip may also be employed. After preliminary evacuation, the carbonate is heated to at least 1000‹ C. and thus converted into oxide. During the process of degassing the electrodes the oxide may absorb gas and be partially converted into hydroxide or carbonate ; it may be reconverted to oxide by a second heating, preferably, but not necessarily, as high as 1000‹ C. The vessel is then sealed off and the oxide absorbs residual gases in the manner of an ordinary getter. Specifications 211,149 and 241,556, [both in Class 39 (i)], are referred to.

Abstract: 1,025,714. Tubular films. NATIONAL DISTILLERS & CHEMICAL CORPORATION. Oct. 10, 1962 [Oct. 10, 1961], No. 38406/62. Heading B5B. Tubular thermoplastic film is made by extruding a molten thermoplastic material through a die orifice formed by two parallel slits interconnected at each end and opposing sides of the tube are held apart for separate cooling by permitting air to enter the tube through the portion of the die which is between the two slits. Both the flat sheet portion and interconnecting bead portions of the tube may be of a substantially uniform guage, or one of the flat sheet portions may be of a gauge greater than that of the other, or the bead portions may be of a gaugesubstantially greater than that of either of the flat sheet portions. In apparatus as shown, the molten thermoplastic material passes through the extruder barrel 2 into the extrusion head 1 by way of conduit 51, and into the passageway 52. Thence the flow is divided by the fluid conduit element 68, to pass upwardly around the air blade 9 (Fig. 2, not shown) and outwardly from the continuous orifice formed by the air blade 9, die. lips 5 and 6, and deckle plates 61. Air blade 9 comprises two parallel sides 9a and 9b, each having semi-circular recesses at intervals therein, the recesses in the two sides being opposite each other so as to form a series of cylindrical air blade passageways 70 (Fig. 2, not shown). A chilled fluid, e.g. refrigerated air, is introduced into the conduit element 68 and is discharged by way of the air blade passageways 70 between the two sides of the film, so as to keep them apart and urge them into surface contact with the chill rolls 25. Rolls 25 are chilled by circulation of a refrigerated liquid, e.g. water, through the conduit system 35, 24, 36 and driven by motor 31 through the chain and sprocket system 28, the film passing between the rolls 25 to the nip rolls 41, 42. By means of bolts 62, 65, die lips 5 and 6 may be moved laterally to adjust the width of either side of the film. By means of bolts 84 (Fig. 2, not shown), the deckle plate elements 61 (Fig. 2, not shown) may be moved laterally to adjust the width of either end-portion of the film.

A floor truck cable tow conveyer system comprises, a channelled guide rail 1, Figs. 1, 2 and 3 embedded within a floor and an endless wire cable 2 movable along the rail, the cable 2 having secured thereto at predetermined intervals pusher lugs 9, to engage and propel a tow pin 3 depending from a floor truck, which pin presses through a guide slot 11 of the rail, a joint lug or lugs 8, for connecting cable ends and intermediate spacer lugs 10, which together with the lugs 9, 8 are arranged so as to be received in mating recesses in driving, tensioning and cable direction deviating wheels of the system. The lugs slidably engage a slide strip 13, Fig. 4, secured along the interior bottom wall of the rail, the strip being located by pins 14 on the strip engaging holes 15 in the rail bottom wall. Each pusher lug is described in detail with reference to Figs. 8 to 11 (not shown) and as shown in Fig. 4, has a transverse slot to receive the pin 3 bordered by projections 26, 25. The projections are inclined downwardly to the rear and front of the lug in the direction of movement of the cable. The pin 3 can move up and down in known manner relative to such inclined portions when engaged thereby. The cable passes through a hole in the lug and is gripped by screws threaded into the lug. The hole may be plain, or grooved to increase the grip as desribed in modifications. Feet 29 on the lug engage the strip 13. The or each joint lug 8 is described with reference to Figs. 12 to 14 (not shown), and consists of a framework with a top cover sloping rearwardly and forwardly, housing two abutting and opposed tapered sockets to receive cable ends. Each intermediate lug has a grooved through hole with a central enlargement and threaded and/or plain holes, which threaded holes receive gripping screws, as described with reference to Figs. 34 to 37 (not shown). Horizontal chain deviating wheels are arranged in pits formed in the floor and provided with covers slotted to receive the pins 3. The cover is secured to the top of the wheel shaft and the wheel has rectangular recesses spaced therearound at the same spacing as the lugs on the cable. The latter is received in a V-groove in the wheel. A driving wheel for the cable is horizontally arranged in a floor pit and the slotted cover therefore engages rollers carried by the wheel which is driven by bevel gears from a horizontally arranged motor. A tensioning device comprising a pair of longitudinally spaced and laterally offset vertical wheels, one of which has its axis adjustable by a bolt, is described with reference to Figs. 22 to 24 (not shown). Switch devices for tow pins moving along a main line to a branch line or vice versa are described with reference to Figs. 25 and 28 (not shown). In the first instance the switch plate is power operated and in the other it is not, and then works in conjunction with a known detector means to prevent two trucks entering the main line simultaneously.

Abstract: 965,674. Waveguide switches. NIPPON ELECTRIC CO. Ltd. Oct. 27, 1961 [Dec. 5, 1960], No. 38567/61. Heading H1W. A microwave switch comprises a length 31 of waveguide of rectangular or other section, a coaxial ferrite rod 15 and a metal plate or a pair of metal plates 35, 36 arranged in an axial plane contiguous to the rod. As shown, the plates are about the same length as the rod and extend the full distance from the rod to the short sides of the waveguide. If an axial magnetic field is applied to the ferrite rod by means of a coil 40, the transmitted wave suffers an attenuation which varies with the coil current I in the manner indicated by curve S. This attenuation is mainly caused by reflection. Curve # shows the phase-change undergone by the transmitted wave, this wave being very small in amplitude and of rapidly varying phase in the region of maximum attenuation. In the switching circuit of Fig. 4, two switches are arranged in similar waveguides 53, 54 connecting the symmetrical arms of two magic-T junctions 51, 52, one switch being one quarterwavelength nearer the junction 51 than the other switch. When no current is applied to the switch coils, energy is transmitted from the E-arm 20 to the E-arm 25 without attenuation. If currents IA, IB are applied to the coils, most of the input energy is reflected by the switches (see Fig. 3) and, because of the path difference of a half-wavelength, the reflected waves combine in the H-arm 26 where they are absorbed by a dummy load. The transmitted waves are of very small amplitude and suffer a differential phase-change of a half-wavelength on passing through the switches (see Fig. 3). They combine in the H-arm 26<SP>1</SP> and are absorbed by a dummy load. In a modification (Fig. 5, not shown), the dummy load in the H-arm 26<SP>1</SP> is replaced by a second transmitter. This normally functions as a stand-by, its output being absorbed by the load in arm 26. When the switch is actuated, the output of the stand-by is reflected into the arm 25. Specification 733,486 is referred to.

Abstract: 868,295. Winding webs. HARNDEN Ltd., C. A. Oct.. 19, 1959 [Nov. 29, 1958], No. 38571/58. Class 100(1) A machine for winding web material has a winding shaft 14 driven through a steplessly variable speed gear 21 which is adjusted to vary the input/ output rates in accordance with the diameter of the roll being wound. As shown, the web is rewound, after slitting, on shafts 13 and 14. An input shaft 20 of the variable speed gear 21 is driven by a shaft 16 through pulleys 17, 19 and a belt 18, whilst an output shaft 22 drives the shafts 13, 14 by a belt 24. An electric motor 27 drives a speed adjusting shaft 31 of the gear 21 and a sprocket 33 on a worm shaft 34 which drives a speed adjusting cam 35 engaged by a cam follower roller 37 on a bell-crank lever 38. The bell-crank lever 38 is connected to a bell-crank lever 40 by a link 39, the bell-crank lever 40 being connected to a link 41 having an arm 42, Fig. 3, carrying a switch 44 having a pivoted operating arm 45. A switch operating lever 46 is rocked about a pivot 43 by an arm 47 and a link 48 connected to an arm 49 of a bell-crank lever having a second arm 50 sensing the diameter of the roll being wound on the shaft 14, Fig. 1. As the roll being wound increases in diameter the lever 46 recedes from the switch 44, thereby causing energisation of the motor 27 which . drives the speed-adjusting shaft 31 to reduce the speed of the output shaft 22 and thus the speed of the shaft 14. The cam 35 is also driven to rock the follower 37 away from the axis of the cam 35, thereby displacing the arm 42 towards the lever 46 to de-energise the motor 27. This sequence is repeated until a cam 36 engages a switch 53 to switch off the motor 27. The variable speed gear 21 is reset by a motor 56 prior to a further winding operation.
