Lamps forming a line of light; lantern doors and screens.-The framework of batten lights or footlights is built up of frames 4 and a pair of angle-irons 1, 2 forming a channel in which the supports 6 for the reflectors and electric-lamp holders are slidably mounted, and sheet metal covers 13 are hinged on rods 12 extending between the legs of the end frames, the covers 13 enclosing the whole of the sides and top and being held in the closed position by hinged clips 14. The supports 6 are provided with bridgepieces carrying terminal blocks 5 and bolted to the angle-irons. The reflectors 8 are of prismatic glassware and are cut off vertically so as to allow of the spread of light along the length of the batten. Illuminating units are preferably in pairs giving a definite colour with an opaque division between different coloured pairs. Colour effects are obtained by coloured gelatine screens sliding in frames resting on a tray 23 hinged to the batten and held in position by pins passing through legs on the tray and holes in the frame 4. The opaque screens 20 may be carried by cross members adjustably bolted to the tray. The first Provisional Specification describes a batten comprising longitudinal angle-irons, transverse T-pieces bolted thereto, and iron stays fixed at intervals along the batten and secured by tie-rods to the T-pieces. The terminals of each lamp holder are mounted on an insulating block on a cross-strap bolted to the angle-irons, and the lamp holder can be withdrawn through the bottom of a reflector gallery and the reflector on releasing thumb-screws. A cover for the framework of the batten is detachable in sections so that the whole of the batten, including the wiring trough, is open to inspection.

Title: Improvements in and relating to presses for vulcanizing a rubber article such as a pneumatic tire
IPC: B29D30/06
Filed: 1939-03-24
Abstract: 526,659. Moulding and vulcanizing tyres &c. McNEIL MACHINE & ENGINEERING CO. March 24, 1939, Nos. 9295 and 9296. Convention dates, April 1, 1938 and Sept. 21, 1938. [Classes 70 and 87 (ii)] A rubber article such as a pneumatic tyre is stripped from the two co-operating parts or sections of a vulcanizing mould by causing one part to be moved across the other to compress the article and thereafter causing the mould parts or sections to open while maintaining the article in its compressed condition. 'The lower section 1, Fig. 1, is fixed on a base 15 having a fixed shaft 16 whereon is pivoted links 18 pivotally connected at 19 to rocking arms 20 pivoted at 21 to a platen 22 carrying the upper section 2. The arms 20 are connected by a web 24 and their upper ends are connected to operating links 34 which are pivoted at 36 to plates 38 fixed to gears 39 mounted on a drive shaft 40. The platen is provided with wings 55 having forked extensions 57 carrying rollers 58, 59 engaging cams 60, 61 on the shaft 40. In operation, in the opening of the mould the cams 60 lift the rollers 58 and thus the section 2 rises slightly so that bevelled surfaces 10, 11 on the sections are cleared. The links 34 operate to tilt and lift the section 2 and the cams 61 move the rollers 59 to drag the section 2 laterally of the section 1. On closing the mould, the concentric surfaces of the cams 61 engage straight sides of the forks 57 such that the final closing movement is in a straight line with the mould sections parallel. The section 2 is secured to the platen 22 by screws 26 in adjustable bushings 28. Insulation 29 may be provided between the mould and the platen. In another form, Fig. 17, the movements are controlled by fluid-pressure cylinders. The upper mould section 110 is pivoted at 148 to arms 147 connected intermediately of their ends to a piston roa 153 of a cylinder 154. The lower ends of the arms 147 carry rollers 149 engaging inclined tracks 150. The cylinder 154 is pivotally mounted on arms 156, 157. The section 110 is also pivoted by ears 161 through slotted connections 163 to arms 164 pivoted to a fixed bracket 133. In operation, the rear side of the section 110 is lifted slightly to clear a flange 117 on the section 111 and it is then moved across the section 111, tilted and pivoted about the roller 149. The section 111 may be lowered by toggles 120, 121 operated by a piston 139 from a cylinder 138 and by arms 143 pivotally connected to the cylinder 138 which is mounted pivotally on arms 140. The upper position of the section 111 is adjusted by moving a casting 122 to which the toggle arms and the arms 157 are connected. The casting 122 is adjusted by screws 131 and is secured in position on a central pillar 119 by nuts 127, 128. The mould sections are locked together when closed by rotating the pillar 119 so that the head 183 thereof engages projections 186 on the section 110. The pillar is rotated by gearing 167 operated from a fluid-pressure cylinder.

Title: Method of preventing oscillations in travelling wave tubes
IPC: H01J23/30
Filed: 1948-04-02
Abstract: 660,793. Travelling-wave tubes. STANDARD TELEPHONES & CABLES, Ltd. April 2, 1948 [July 3, 1947], No. 9305/48. Class 39 (i). In a travelling wave amplifier in which an electromagnetic wave travels along a helix 5, Fig. 1, with a velocity slightly less than the beam velocity and is continuously amplified as it travels, it is found that even when the product of the gain of the forward wave and of the attenuation of the reflected wave is much less than unity the device still tends to oscillate; this is stated to be due to the simultaneous presence of a wave in a fast mode travelling along the helix with approximately light velocity, and consequently means must be provided for preferentially damping out the wave in the fast mode while leaving the slow mode substantially unaffected. It is shown graphically that the electric field intensity of the slow mode falls off more quickly in a radial direction than that of the fast mode so that by placing lossy material 26 where the field. of the slow mode is almost zero while the field of the fast mode is still considerable, the desired preferential damping effect is achieved. The lossy material may be a self-supporting cylinder 26 of granulated carbon in a binder, or a thin carbon or metal coating, whose thickness is small compared with the skin depth, on the outside or inside of the tube wall, Figs. 3, 4 (not shown). The helix 5 is coupled to input and output rectangular wave-guides 21, 23 by stubs 19, 20 attached to metal collars 17, 18 fitting the tube wall. The electron gun comprises indirectly heated annular cathode 2 and focusing electrodes 3, 4. A focusing coil 25 is provided. Specification 652,155 is referred to.

Filed: 1966-03-03
Abstract: 1,128,512. Luminescent materials and uses thereof. GENERAL ELECTRIC CO. Ltd. 3 March, 1967 [3 March, 1966], No. 9377/66. Heading C4S. A luminescent material, excitable by U.V. above or below 3000 Š, cathode-rays or X-rays, consists of yttrium vanadate, Y 2 O 3 V 2 O 5 , activated by bismuth; the yttrium may be wholly or partially replaced by gadolinium. The preferred percentage by weight of bismuth is 0À5 to 10, particularly 1 to 4. The departure from stoichiometry should not be more than 0À04 mole excess either way. In preparations described, starting materials include Y 2 O 3 , V 2 O 5 , Bi 2 O 3 , NH 4 VO 3  and Gd 2 O 3 which may be heated to at least 800‹ C. in an oxidizing atmosphere, and subsequently heated to 1000‹ to 1250‹ C., for example 1 hour at 800‹ C. in air, followed, after crushing, by heating at 1100‹ C. in air for 1 hour, or heat cycles of 2 hours at 1000‹ C.; the addition of suitable alkali metals such as carbonates, nitrates, or chlorides (sodium chloride to give 0À1% by wt. of Na for instance) reduces the temperatures required. Yellow emission under 2537 Š and 3650 Š excitation is mentioned, uses including high and low pressure mercury lamps, cathode-ray tubes and X-ray screens.

Title: Improvements in or relating to work-clamping devices for electric welding machines
IPC: B23K37/04
Filed: 1944-05-18
Abstract: 583,910. Welding. WOODHOUSE & MITCHELL, Ltd., and FORBES, L. May 18, 1944, No. 9526. [Class-83 (iv)] The work clamping jaws of an electric welding machine are first closed on the work by manual operation, other manual means then bringing into play hydraulic clamping pressure, unclamping being effected by manual means. which first relieves the hydraulic pressure and then opens the movable jaw clear of the work. The movable jaw b is carried by a slide c operated by a rack g and pinion f on a handrotated shaft e. The shaft is screw-threaded at e<1> between collars i, i<1> and engages the threaded boss of a hand wheel h. The back of the slide carries a ram d<2> in a cylinder d<1> connected through a spring-closed valve m with a reservoir n and through a pipe p with a cylinder p<1> containing a hand-operated pump piston p<2>. In order to clamp the work, the hand wheel is rotated so as to move outwards. It first moves away from a rod j connected by a rocker k to the valve which is thus closed by its spring m<1>. When the hand wheel engages the collar i, further rotation rotates the shaft e and causes the jaw b to move down to grip the work, fluid from the reservoir being drawn into the cylinder through the valve m. The piston p2 which is spring controlled is then pushed forward by a hand-operated eccentric r to push oil from the cylinder p<1> through a non- return valve p<4> and pipe p into the cylinder d<1> to apply the hydraulic clamping pressure. On returning the eccentric, the piston p<2> is pushed back by its spring r<1> and oil is drawn into the cylinder p<1> from the reservoir through the non- return valve p<3>. In order to release the work, the hand wheel is rotated in the other direction, which first causes the rod to be pushed upward by the chamfered end h<2> of the boss so as to open the valve m and then causes' the shaft e to rotate to raise the jaw b.

Abstract: 663,469. Wire strainers. DISTILLERS CO., Ltd., and HART, K. C. E. April 4, 1950 [April 8, 1949], No. 9552/49. Class 45 A wire tensioning tool comprises two levers 1, 2, pivoted together on a common pin 7 to form two handle members 3, 5, and two jaw members 4, 6 arranged so that compression of the handle members forces the jaw members apart, one of the jaw members 4 having a guide hole 20 through which the wire may pass, the lever 2 having the handle 5 and jaw 6 independently pivoted on the pin 7, a link member 10 connecting the jaw member 6 and the handle 5 so that a gap is provided between the link 10 and the jaw 6 through which the wire may pass when the handles 3, 5, are in open position and which gap is constrained when the handles are forced together. The handles are held in their open position by a spring 9 and in this position the jaw 6 is urged against the jaw 4 by a spring 8 which is weaker than the spring 9. When the handles are forced together the spring 9 forces the upper parts of the jaw 6 and link 10 together to close the gap between them to grip the wire and further movement of the handles tensions the wire. A cutter 18 is slidably mounted on the inside of jaw 4 adjacent the aperture 20. A pivoted lever 14 having a cam at its end, moves the cutter across the aperture to cut the wire.

Filed: 1962-03-13
Abstract: 932,004. Stacking sheets. S. D. WARREN CO. March 13, 1962 [March 13, 1961], No. 9614/62. Class 100 (1). Sheets 93 are delivered from a paper-cutting machine at a high speed by a tape delivery system of the kind described in Specification 932,003 and are retarded by a suction roller 72, which rotates in an anticlockwise direction, Fig. 2, at a peripheral speed less than the delivery speed of the sheets, before being stacked on a platform 91. 49 and 63 are the end rollers of the tape delivery system and a guide plate 94 directs the delivered sheets into peripheral contact with the suction roller 72. The roller 72 slows the sheets down so that they are not damaged when their leading edges come into contact with an end stop 71. The platform 91 is supported at each corner by a chain 92 and is vertically movable within a framework by means of an hydraulic ram 90. The ram 90 is actuated by means of a photo-cell 97 via a control device 98. The photo-cell 97 is disposed in the same horizontal plane as the axis of the roller 72 and emits a signal when the stop 83 of the stack of sheets on the platform reaches the level of the photo-cell; this signal causes the ram 90 to lower the platform. The suction roller 72 is hollow and has portions 70 and 81 of respectively lesser and greater diameter. Suction ports 82 are formed in the greater diameter portions 81. Fingers 73 carried by a shaft 80 disposed below and parallel to the roller 72 are movable, by oscillation of the shaft 80, between the full-line position of Fig. 2, in which they lie adjacent to the lesser diameter portions 70 of the roller 72, and the dotted-line position in which they engage the rear edge of the stack of sheets for knocking-up the stack. Perforated plates 85 are mounted on oscillating shaft 87 at each side of the stack and effect side-jogging. The positions of the shafts 87 and the end stop 71 are adjustable so as to accommodate sheets of different sizes. A photo-electrically operated counter, not shown, is stationed in the path of the incoming sheets and controls means for inserting a ticket in the stack of sheets to divide the stack into counted batches.

Abstract: 417,385. Toy figures. BANNISTER, G. A., Oakdene, Plumpton, near Lewes, Sussex. March 30, 1933, No. 9649. [Class 132 (iii).] A device for use in the construction of bendable washable woollen toys comprises a shaped frame or frames having a longitudinal internal aperture over which are wound windings of textile materials and through either end of which can be passed a flexible wire member which is joined at its ends to form a binding for the windings. As shown in Fig. 3 wool 4 is wound round the frame 5 of wood, vulcanite or metal, slotted at 6 and grooved on each longitudinal edge 7. A length of wire 1 is passed through the uncovered ends of the slot 6 and around the wool windings 4, the ends of the wire being joined. The wire 1 is then sewn to the windings 4 by wool 9 and the wool windings 4 are cut by passing a thin edged tool, e.g. a safety razor blade, knife or thin scissors, along the grooves 7. The member thus formed is removed from the frame 5 and by twisting the wire 1 into helical form a cylindrical brush-like member 10, Fig. 6, is obtained. Two members 10 can be laid across a frame 11, Fig. 6, in the shape of the body and head of a toy figure, the wire 2 being passed over the members 10 and the stitching 14 securing the windings 13 and the members 10 to the wire 2. The members 10 form the legs of the figure and a member 8 smaller than 10 can be provided for the tail. The ears of the figure can be crocheted and sewn to the toy and the eyes can comprise small buttons or sequins or the ends of a knotted thread. Wools of different colours are employed, e.g. to produce a black face or black paws.
