Patent GB-858833-A (GB)
Title: Double-billet extrusion presses
IPC: B30B15/24
Filed: 1957-05-02
Abstract: 858,833. Extruding. SCHLOEMANN A.G. May 2, 1957 [May 19, 1956], No. 14002/57. Class 83 (4). In the simultaneous extrusion of a pair of billets by means of a pair of rams 6, equal pressures are initially exerted on the two billets and subsequently the positions of the two rams are synchronized for equalizing the size of billets in the two containers 2. The two rams 6 are actuated by pistons 7 working in cylinders 8 whose pressure spaces may be connected together directly by pipes 9 through a valve 10. The pressure spaces are also connected through pipes 27a, 27b to a synchronizing slide valve 14 whose valve element 22 is coupled by a rod 21 and links 19, 17 with a mechanism 15, 16 responsive to the positions of the two rams, and also with an indicator 24, 26. The exhaust from valve 14 is connected through a throttle valve 31 having a hand lever 32. Initially the valve 10 is opened by an electromagnet 11 energized by switch 35 which is closed by lever 32 when throttle-valve 31 is closed. Pressure liquid is then admitted from an accumulator to the pressure spaces 8a through pipe 36, control device 37, pipes 40a, 40b and adjustable valves 41. After the billets, which may be of aluminium, have been compressed against the residue of the preceding billets to become welded thereto, high-pressure liquid to effect the extrusion is then supplied to the cylinder spaces 8a through pipes 12 and non-return valves 13, and if the indicator 24 shows a difference in ram positions, the valve 31 is gradually opened whereby the synchronizing valve slowly equalizes the piston positions and hence the container contents. When the valve 31 is fully open extrusion proceeds through die 5 under the control of the synchronizing valve. The highpressure liquid may be supplied by separate sets of identical pumps as described in Specification 802,615.

Title: Improvements in electric discharge tubes and circuit arrangements incorporating such tubes
IPC: H01J43/02
Filed: 1938-05-11
Abstract: 500,090. Discharge apparatus; electron beam valves and circuits therefor. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 11, 1938, No. 14041. Convention date, May 14, 1937. [Classes 39 (i) and 40 (v)] In a discharge tube, such as a mixer tube for superheterodynes, employing double control over an electron system, the electrons from an indirectly-heated cathode 17, Fig. 3, pass through a control grid 18 and a screen grid. 19 and are formed by electrodes 21, at cathode or negative potential, into beams which pass along curved paths 22 to other electrodes collecting primary or secondary electrons, all the electrodes being surrounded by a control electrode 30 of solid material; the first control is exerted by control grid 18 adjacent the cathode and the second control by electrode 30 acting in a part of the discharge space from which electrons cannot substantially return to the first control electrode, the paths over which the electrons are affected by the second control electrode being considerably longer than the paths over which they are affected by the first control electrode. The electrodes 21 may bo replaced by solid portions of the control grid, which may be entirely of rods. The beam may be deflected to strike one or the other of the two electrodes 25, 29; the output circuit may be connected between these electrodes or to one of them. Alternatively the electrode 25 may be coated with secondaryelectron-emissive material and provided with apertures 26, behind which is a positive collector electrode 27. The deflected electron beam either strikes the electrode 25, dislodging secondary electrons which pass to anode, 29, or passes through apertures 26 to electrode 27. In a modification, the electrode 27, Fig. 3, is kept at cathode or negative potential so that electrons passing through the apertures 26 are driven back to the electrode 25. In this case the valve may be used as a self-oscillator, as shown in Fig. 6, in which the control electrode 30 and the electrode 25 form the oscillator section, the output circuit being connected to electrode 29. Magnetic or electrostatic fields may be employed to assist the second control electrode to deflect the electrons into curved paths. The Specification as open to inspection under Sect. 91 includes also a modification, Fig. 4 (Cancelled), in which four beams issue from the cathode and pass to two gauze electrodes 29 behind which are secondary-emissive electrodes 25. The beams either pass through the apertures in anode 29 to the electrode 25, from which secondary-electrons are returned, or strike the support rods 27 of the anode 29. The focusing electrodes 21 are, in this case, outside the screen grid. This 'subject-matter does not appear in the Specification as accepted.

Title: Reciprocated suction feeder for sheets
IPC: B65H3/12
Filed: 1964-04-06
Abstract: 1,042,653. Feeding sheets. A. F. SHIELDS. April 6, 1964 [April 12, 1963], No. 14041/64. Heading B6B. In apparatus for feeding sheets or blanks to a machine, such as a paper box-making machine, a stack of sheets is supported in a magazine 15 between front and rear inclined guides 27, 17 and side guides 31, which are all adjustable, and rests on a front slat or table 25 which can be reciprocated horizontally and has a number of apertures in the front top surface communicating with a source of vacuum. The front guides 27 can be adjusted vertically to allow only one sheet at a time to be separated from the bottom of the stack by the table 25, and the separated sheet is then gripped between feed rollers 33, 34, which are both positively driven, and fed to the machine. The table 25 is secured to a pair of carriages 24 having rollers 23 which run in guides 21 of frames 20, and the carriages are reciprocated from a rocking shaft 60 by arms 63 and links 65. The table 25 is hollow and made of an aluminium alloy, and has four equally spaced front fingers 105-108, Fig. 6, which have conical suction apertures in their upper surfaces. A suction inlet 98 in the base of the table communicates with each of the hollow fingers 105-108 through passages created by inserts 101-104 of balsa wood or other light-weight material arranged within the table. When narrow sheets are stacked in the magazine 15, one or both of the outer fingers 105, 108 may be sealed from the source of suction by gates 120 which are operated by rack-and-pinion means 122 from a tool inserted through apertures in the upper face of the table 25. A pipe 95, Fig. 6, fixed over the suction inlet 98 of the table fits slidingly within a fixed pipe 93 which leads to a valve 56, a pipe 71 connected to a suction pump driven continuously by a motor. The valve 56 is opened to atmosphere, or allows suction to be established at the table 25, on the operation of a rod 81 which can be reciprocated through flexible couplings 83, 85 from a face cam on a constantly rotating shaft 55. The feed roller 34 comprises spaced rollers 34a, 34b, 34c which allow the passage of the suction fingers 105-108 on the table 25. In operation, with the table 25 in its most rearward position, the valve 56 allows suction to be established at the table to grip the bottom sheet of the stack. As the table 25 moves forward, a portion of the pipe 95 is withdrawn from the fixed pipe 93, thereby increasing the volume between the valve 56 and the table 25, thus creating a greater suction effect rapidly. The table carries the bottom sheet beneath the guides 27 to the nip of the feed rollers 33, 34, whereupon the valve 56 is opened to atmosphere. In a modification (Fig. 10, not shown), separation of each sheet by the reciprocating suction table 25 is assisted by a mechanical means comprising a resiliently mounted transverse gauge which is reciprocated and abuts the rear end of the sheet.

Title: Improvements in or relating to maximum demand indicators
IPC: G01R11/56
Filed: 1930-05-08
Abstract: 353,562. Supply meters. ARON ELECTRICITY METER, Ltd. and HILL, E. W., 80, Salusbury Road, Kilburn, London. May 8, 1930, No. 14192. [Class 37.] The invention relates to maximum demand indicators of the type wherein the indicating-pointer driving member is driven by an electric mechanism which is periodically energized by means controlled from an associated registering meter, the said driving member being automatically disconnected at intervals from its driving means and returned to zero, and consists in forming the electric mechanism as an A.C. magnet having a pivoted armature engaging a toothed wheel, the armature being mechanically disconnected from the wheel when the magnet is energized. A toothed wheel 71<A> is secured to the rotating spindle of an integrating meter the maximum rate of registration of which is to be indicated. As the wheel 71 rotates spring contacts 73, 75 are momentarily closed to shortcircuit an A.C. magnet 13 an armature 17 of which then rocks under the action of a spring 19. An extension 23 of the armature comes into the path of a weighted rod secured to a shaft 33 carrying a two-armed lever 31 having pins 35 engaging a star wheel 37, the lever 31 being rocked to cause the lower pin 35 to move the star wheel forward. The re-energization of the magnet 13 causes the extension 23 to move away from the rod 39 whereupon a weight 41 rocks the upper pin into engagement with the star wheel. The motion of the star wheel is transmitted to a pinion 43 gearing with a wheel 51 which carries a rod 5 bearing a short pointer 7. The rod 5 engages a pointer 3 frictionally mounted on an annulus 9 and settable to zero by hand. The spindle of the pinion 43 is carried by an arm 45 which is rocked by predetermined intervals (e.g. every 30 minutes) by the contacting of a pin 69 with a tail 71, whereupon the wheel 51 and rod 5 are returned to their zero position by a spring 53. The pin 69 is secured to a disc 67 driven through gearing from a constantspeed shaded pole electric motor.

Abstract: 577,128. Automatic control systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., ROSEBY, P. N., and HAIGH, R. D. July 26, 1944, No. 14234. [Class 38 (iv)] Temperature.- In a control arrangement for an electric hotplate employing a heating element embedded in refractory cement, the variation of the cement resistance with changes of temperature is arranged to operate a relay device controlling the circuit of the heating element. As shown the heating element 10 is enclosed in a metal container 11 and a plate 13 is separated from the element by a thin layer of cement. When the temperature reaches a predetermined value the leakage current through the cement between the heater 10 and plate 13 operates a relay 14 which controls a normally closed switch 15, the relay being either of the thermal or electromagnetic type. When an' electromagnetic relay is used, the switch 15 is connected in the neutral conductor N. The relay may be arranged to light a lamp or operate a signal. For operating the hotplates in series another plate similar to plate 13 is used. One plate is connected through the relay to the neutral conductor, the other plate being connected to the line. The temperature at which the relay will operate can be varied by including aÀ variable resistance in circuit with the relay.

IPC: B65B53/02
Filed: 1968-03-26
Abstract: 1,220,188. Coating apparatus. G. LOUDA. 26 March, 1968 [11 Nov., 1967], No. 14421/68. Heading B2L. [Also in Division B8] In a machine for applying molten plastics beadings to shrink-wrapped packages, the beading material, which can be a mixture of polyethylene and bitumen at a temperature of 150‹C-200‹C, is extruded from nozzles onto the package as it is moved past the nozzles, so that the material bonds with the wrapping e.g. also polyethylene. A preferred package has two plastics beadings 2 adjacent each of for edges Fig. 1, however the beadings can also be circumferential Fig. 4. A machine, Fig. 5, to produce a package of the former type, but with just one beading along each of the four edges Fig. 2 (not shown), has a table 18 onto which the shrink wrapped packages 12 are fed by a conveyor 10. The packages 12 are positioned on this table by rams 34, 22, (24) Fig. 6 (not shown). The table then descends simultaneously with with molten plastics material being extruded from four nozzles 38, one extruding onto each vertical edge. The nozzles can be screw, or piston and cylinder fed, and are stopped extruding by a switch or photo-cell 40, responding to the package. A further photocell 42 of adjustable height sends a signal via a relay 46 when it is cleared by the package, to operate the discharge conveyor 44. A switch 54 operated by the incoming package or by flights 52 of the conveyor 10 may initiate the machine cycle. Another embodiment, Fig. 7, is a machine for extruding the beading circumferentially around the package, in which the package 60 is gripped between plates 62, 64 and rotated about the axis of shafts 66, 68 below, at least, one nozzle 98, adjustable vertically and parallel to the shafts. To maintain the same distance between the nozzle and the package during extrusion, in the case of polygonal-section packages, the shafts 66, 68 are maintained on a carriage 72 which is raised and lowered by cranks 90 and 92, see also Fig. 8 (not shown), or other means (not detailed) producing vertical motion.

Abstract: 235,391. Ellis, W. J. June 17, 1924. Embossing-surfaces.-Dies for embossed printing are produced by providing both sides of a sheet of paper with registering impressions, coating the impressions with powdered resinous or other self-hardening material, and then heating to cause the resin to swell up and harden. Several such sheets may be superposed to obtain the desired elevation of design, and a female die to co-operate therewith is provided by impressing the die into a soft or pliable substance placed or coated on a block which will harden after receiving the impression. An imprint of the type &c. is first made, as indicated at 11<1>, Fig. 3, on the bed 11 of a press which carries the usual gauges, so that an imprint on the upper face of a sheet of paper laid on the bed against the gauges will register exactly with that on the bed below the sheet. The imprint on the bed is transferred to the lower face of the sheet at the same time as the upper face is printed. Dusting of the impressions with resin, and then heating, results in a sheet 10 with raised designs 14, 15 on each side, as shown in Fig. 8. The complete die, shown in Fig. 9, comprises three of these sheets 16, 17, 18, with their raised parts 19, 20 superposed.
