Title: Improvements in or relating to methods of and apparatus for festooning materials
IPC: D05C7/08
Filed: 1933-05-27
Abstract: 420,373. Festooning webs. CARRIERROSS ENGINEERING CO., Ltd., 101, Regent Street, London, and WARD, S., Stanmar, Grosvenor Road, Orpington, Kent. May 27, 1933, No. 15398. [Class 100 (i)] A web of paper, fabric, or other material is fed between the festoon-supporting members of #, moving conveyer by a device moving laterally with the conveyer during the formation of each festoon, the feed of the web being directed and assisted by means of fluid pressure. In the form shown, the conveyer chains supported by the runways 6 carry cross-bars 5, above which is mounted a tapered duct 11, through which the web A is fed. This duct is mounted on a block connected to a rod 15 actuated by a snail cam 9 driven from the same source as the chain sprockets, and is balanced by a weight 20; or this weight may be otherwise disposed to ensure good contact of rod and cam. A spring 15<a> and buffer 16 are provided to assist the sharp return of the duct, which is arranged to travel in an inclined path. In this sharp return, the end of a festoon is wrapped over the rearward bar, and is held thereon by a curved rubber flap 21 mounted on the duct. Air from a fan is fed on to the front face of the web from a pipe 23b through a flexible connection 23<a>, a tapered pipe 23 carried by the duct, and a nozzle 24. Compressed air is forced from a pipe 25 in jets having an angle of 30‹ to the vertical on to the back face of the web. The pipe 25 may be arranged to move with the duct. The conveyer may be provided with loose bars which are fed alternately with a step-by-step movement of the conveyer. Either or both of the air supplies may be of compressed air or fan-pressed air. The snail cam may be replaced by other timing means giving reciprocation of similar character.

Abstract: 1396058 Two part couplings STAFF KG 30 March 1973 [1 April 1972] 15453/73 Heading H2E An adaptor to connect to a wiring track 31 at any point in its run is preselected to connect to the neutral N and any one of R, S, T live rails before insertion. On insertion and rotation of the adaptor body, spring loaded contact 9 mates with N rail, and contact 12<SP>1</SP> with any of R, S, T according to its position. Spring loaded earth contact 191 mates with earth rail 43. Lugs 5<SP>1</SP>, 61, 7<SP>1</SP> engage ribs on the track while projections 22 on slidable clamping plate 4<SP>1</SP> engage the opening of the track. Inward splines on plate 4<SP>1</SP> engage grooves 24<SP>1</SP> on the body to prevent relative rotation. After insertion and rotation, screwed sleeve 2<SP>1</SP> is tightened, pulling back lugs 5<SP>1</SP>, 6<SP>1</SP>, 7<SP>1</SP> to clamp the adaptor. Selection of the circuit required is made before insertion by sliding insulating ring 13<SP>1</SP> into an intermediate position in its range, when a fork or contact 12<SP>1</SP> embracing the central flat conductor rod becomes free to rotate. Alter setting the required angular position of contact 12<SP>1</SP>, ring 13<SP>1</SP> is moved to one or other end of its range, when projections engaging with the body or cap 14<SP>1</SP> prevent further rotation, cap 14<SP>1</SP> being locked to the central conductor rod. Wires from the load are soldered to the ends of the central conductor rod and to a support for neutral (N) contact 9<SP>1</SP>. In another embodiment of the adaptor the cap 14 is detachable, and ring 13 (Figs. 1-6, not shown) can be removed and inverted and/or rotated through 180 degrees before replacement of ring and cap, in order to preselect the required circuit. In a second version of the rotatable part of this embodiment the cap is captive and the contact 12 can be moved axially to two operating levels, while an intermediate level allows rotation through 180 degrees (Figs. 7 and 8, not shown) to select the circuit.

Title: Xerographic toner dispenser
IPC: G03G15/08
Filed: 1960-05-03
Abstract: 881,609. Xerographic toner dispeners. RANK-XEROX Ltd. (Haloid Co.) May 3, 1960, No. 15525/60. Class 98(2). A xerographic toner dispenser includes a rotatable cylindrical container mounted with its axis vertical above a fixed platform and wiper means mounted for oscillatory movement placed between the platform and the lower end of the container to displace the toner from the platform. In the xerographic machine described the xerographic plate comprises a photo conductive layer on a drum which is rotated past a charging station, an exposure station, a development station in which the toner is mixed with the carrier powder and transferred by a belt and a shoot to the drum, to a point where the image is transferred to a continuously fed web of film and is subsequently fixed by resin solvent vapour. The powder is then removed from the drum before the process is repeated. The xerographic powder dispenser is fixed to the machine and comprises a container 63 for the powder which is placed vertically in a rotatable support 62 with its open end adjacent a fixed dispensing platform 54. Between the platform 54 and the container 63 two wiper blades 60 are movably placed. These blades are fixed to a block 56 a pin 61 on which extends through a slot 78 on an arm 77 so that when the arm is oscillated about a screw 76 by a rotating eccentric 20, 85, the blades 60 oscillate and move the powder off the platform 56 and through a supply aperture 52. Simultaneously an oscillating tooth 79 on the arm 77 rotates a ratchet wheel 70 on the support 62 so that the container 63 is rotated. A rod 86 is fixed to platform 54 and extends into the container so that it loosens the powder therein as the container rotates. The eccentric 20 is rotated by a motor (which is controlled by a timer) a control switch of which is operated intermittently by a cam on the before mentioned drum.

Title: Process and apparatus for solidifying substances by continuous cooling
IPC: A23D9/02
Filed: 1955-05-31
Abstract: <PICT:0814803/III/1> A process for the conversion of homogeneously cooling substances such as resins, pitches, waxes and tars, from the liquid into the solid condition with an elongated strand-like shape by means of a flowing liquid cooling medium comprises introduction of the liquid substance into the cooling medium through a heated discharge nozzle arranged below the surface of the cooling medium, the substance being surrounded and moved by a stream of the cooling medium until acquiring stability of shape.  As shown the nozzle 3 is surrounded by a heated jacket 4.  A cooling medium, e.g. water, is circulated by a pump 7 through a cooling tank 11 which may be spiral or sinuous in a vertical plane or straight and which may have constricted or expanded cross-section beyond the nozzle 3 to vary the speed of the cooling medium.  The cooled substance is separated from the cooling medium at a screen 12 and may then be sprayed while on a conveyer 14.  The cooling medium is collected in a tank 13 and filtered, part is then recirculated to the cooling tank through line 19 and part through cooler 8 and line 9. The cooling medium in the tank between lines 9 and 19 is thus relatively warm and sudden cooling of the substance on leaving nozzle 3 is avoided.  The same effect is obtained by dispensing with line 9, placing the cooler 8 in line 19 and giving the heating jacket an open end next the orifice of nozzle 3. Discharged substance on issuing from nozzle 3 is then surrounded by a belt of warm cooling medium (Fig. 1, not shown).  The nozzle may be movable axially along the cooling tank.  Specification 476,361, [Group XII], is referred to.

Title: Voice controlled switching devices for telephone circuits
IPC: H04B3/20
Filed: 1939-05-26
Abstract: 529,788. Two-way repeaters. STANDARD TELEPHONES & CABLES, Ltd., and LATIMER, K. E. May 26, 1939, No. 15709. [Class 40 (iv)] In a system with a number of stations and with means for breaking in, a temporary increase in gain (or reduction of loss) is brought about in the path of the breaking in signals when they first occur. Preferably the increase of gain &c. only takes place for genuine interruptions and not after a period of silence by the other party. In one arrangement, Fig. 1, which is of the kind described in Specifications 456,827 and 465,353, the contacts b are in the condition shown for E-W speech and variable-Á valve V 1  (which is really a tetrode or pentode) is biassed to give a high gain but is ineffective because of the position of contact a. When the W-party breaks in, both contacts change over and V 1   remains in its high gain condition while the condenser in its grid circuit discharges through R 2 . In a modification, Figs. 2 and 3, in which during silence pads P 1 , P  3  are in and pads P  2 , P  4  are out whereas during speech both pads in the speech path are out and both pads in the silent path in, contact c 2  is closed by D  2  during E-W transmission and prepares a high gain condition for V 1  but contact C 1  is normally as shown and keeps the actual gain low until speech is detected by D 1 , whereupon it changes over and the valve V, assumes its high gain condition. If the E-party pauses, contact C 2  opens and the gain of V 1  is reduced by charging K 2  so that only interruptions find abnormally high gain in the transmission path. While the gain in the upper path is abnormally high the lower path is disabled at B. When the detectors D 1 , D 2  operate they control contacts d 1 , d 2 . Consequently if the W-party breaks in, relays Q and P being operated, the change-over of d, opens the lower transmission path. It also shunts out P which after an interval to let the gain of V 1  fall off re-makes the lower transmission path.

Title: Improvements in and relating to wire reinforcements, with particular reference to wire reinforcements for metal cylinders
IPC: F17C1/06
Filed: 1940-11-01
Abstract: 544,952. Storing gases under pressure. BRIDGES, W. Nov. 1, 1940, No. 15970. [Class 8 (ii)] [Also in Group XXII] In applying a helical wire reinforcement to the exterior of a body, such as in reinforcing cylinders for storing gases or liquids under pressure with high tensile wire such as piano wire to afford resistance to penetration from without by missiles such as bullets, bombs or shell splinters, the body is surrounded by a ring, such as a tinned brass or other soft metal ring at least at one end of the reinforcement area which is provided with a projection over which one end of the wire is hooked to secure it and after cooling the wire on the body the other end is secured to the first ring or to a second ring at the other end of the area. The rings 11, 12 which are a push fit on the cylinder 10 and are formed by bending and securing the ends by a soldered dovetail joint, are provided with slots 13 which are closed when the wire is coiled thereon so as to grip the cylinder and prevent slipping thereof round the cylinder during coiling which is effected under high tension. Both rings are provided with attachment lugs 14a, 14b in the event of a single layer of wire being applied, but in the event of a double layer in which both ends of the wire are secured to the same ring 11, the ring 12 may have a flange 15. To apply the wire the lugs on the starting ring are first bent upwards and the starting end of the wire is hooked round one lug and given a few turns round the cylinder, whereupon all the lugs except one are bent down over the wire so as to extend beyond the first two turns. The next few turns are coiled over the lugs and preferably soldered in position. Coiling is then continued by rotating the cylinder in a lathe between a chamfered driven sleeve 19 and a tailstock centre 18, the last turn being laid in contact with the upturned flange of the ring 12. The second layer is then coiled and the last turn is tinned and soldered in position before the tension is released and is then hooked at 21b over the lug 14b which is then bent over the last few turns of wire. The end of the coil is then severed. The turns of the reinforcement may then be soldered together and to the cylinder by rotating in a hot solder bath.
