Title: Improvements in and relating to a method and machine for trimming and cutting paper articles, sheet piles and the like, e.g. exercise books
IPC: B26D1/08
Filed: 1956-06-14
Abstract: 834,667. Trimming &c. books &c. BIEL, H. June 14, 1956 [Nov. 5, 1955], No. 18387/56. Class 31 (1). A method of trimming and cutting paper articles, sheet piles and the like, e.g. exercise books, comprises trimming the work along a long edge in a first direction of feed and performing subsequent trimming operations in a direction of feed angularly displaced from the first direction of feed, the trimming operations being effected by trimming means constantly located with respect to the part of the work to be trimmed. In the machine shown, material A mounted on work-tables A<SP>1</SP> is fed along leg 1, e.g. by means of a conveyer, and trimmed along one longitudinal edge by cutter 3. The material is then fed on another conveyer along leg 2 and while being displaced against a limit stop 4<SP>1</SP> is trimmed along one lateral edge by cutter 4. After displacing the material slightly to the left, by means of a movable stop 5<SP>2</SP>, against a limit stop 5<SP>1</SP>, it is fed under cutter 5 which trims it along the opposite lateral edge. The material is then re-positioned to the right, by means of a movable stop 6<SP>2</SP>, against a limit stop 6<SP>1</SP>, and cut into two sections B by a cutter 6. In the next operation, the corners of the sections B are rounded at 7 by means of punching tools. Finally, the finished products are piled into two bundles, each consisting of five pieces. The round-cornering operation may be omitted.

Title: Method of and apparatus for plating surfaces with tungsten, chromium or molybdenum
IPC: C23C16/16
Filed: 1944-09-26
Abstract: 589,966. Coating metals. WESTERN ELECTRIC CO., Inc. Sept. 26, 1944, No. 18412. Convention date, Sept. 30, 1943. [Class 82 (ii)] In a method of plating metals with tungsten, chromium or molybdenum by decomposition of their carbonyls under reduced pressure, a total gaseous pressure of not more than three mm. of mercury is maintained during the process. As shown, the metallic carbonyls are led by U-tubes 15 and 16 into and out of a water-jacketed tube 10 having one end permanently closed and the other having a removable plug 14, the whole apparatus being mounted for heating in a high frequency coil 23. The outer tube 16 is attached to a vacuum pump and hydrogen may be passed into the tube 10 by a pipe 17b or through the pipe 15. The article 20 to be plated may be supported in the tube 10 by wedge-shaped pieces 21. A vessel 24 surrounding the U-tube 15 contains solid CO 2  during the evacuation of the tube 10 to a pressure of 0.1 to 0.2 mm. of mercury and when plating is started it is replaced by one containing warm water to volatilise the carbonyls. In a modification, 'Fig. 2, not shown, the interior of the tube may be the surface to be coated in which case it becomes the tube 10 and has one end connected to an end piece carrying the carbonyl tube and the other to an end piece attached to the vacuum pump either by cement or by flanges and gaskets, Figs. 3 and 4, not shown. In order to obtain even plating along the inner surface of a tube the carbonyl may be passed through a tube containing inlet and outlet holes and which may itself be water cooled, Fig. 5, not shown. An alloy of the coating metals may be applied by mixing their carbonyls in the U-tube. The Specification as open to inspection under Sect. 91 comprises also the deposition of carbides of the metals from the carbonyls. This subjectmatter does not appear in the Specification as accepted.

Title: Receiver for time modulated electric pulses
IPC: H03K9/00
Filed: 1945-07-19
Abstract: 596,106. Modulated pulse receivers. LORD, A. V., COPE, J. E., and PYE, Ltd. July 19, 1945, No. 18492. Drawings to Specification. [Class 40 (v)] Modulated pulses are de-modulated by applying them to synchronise a relaxation oscillator, which has a natural frequency simply related to the pulse recurrence frequency, and feeding the output to an integrating circuit followed by a low pass filter which cuts off at the highest modulation frequency required. The relaxation oscillator may be operated at a harmonic of the recurrence frequency for ease in filtering, and may comprise a blocking oscillator synchronised by cathode injection and including a parallel capacitor and series resistor as the integrating circuit. The modulated pulses may be separated from other intelligence of lower amplitude on the input waveform, by arranging the oscillator to operate with trigger amplitudes above a certain level only. Specification 564,511 is referred to.

Abstract: 889,465. Nuclear fusion reactors. UNITED STATES ATOMIC ENERGY COMMISSION. June 1. 1959 [June 19, 1958], No. 18549/59. Class 39(4) A thermonuclear reactor comprises an elongated gas-tight insulating chamber filled with deuterium and/or tritium, a conductive shell surrounding the chamber, a first electrical means for providing a first axial magnetic field in the chamber, second electrical means connected to the conductive shell for successively ionising the gas to a plasma and compressing and heating the plasma, and a third electrical means for providing a second axial magnetic field in a direction opposed to the first axial magnetic field. The reactor may be toroidal, as shown in the part sectional view of Fig. 4, and comprises an insulating envelope 115 surrounded by a conductive shell 116 made in two halves of semicircular cross - section separated by insulators, of which one 132 is shown in Fig. 4; the shell 116 does not extend right round the toms but has a gap, terminals being attached to the shell at each side of the gap. The shell is surrounded by a cooling jacket supplied with distilled water and by a coil 120 which produces an axial magnetic field; the coil 120 may be a tube through which a coolant is circulated. Inside the envelope 115 is a coil 135 shaped to screen the envelope from the discharge and cooled by distilled water flowing through it; this coil may be short-circuited or connected to an electrical supply, but in either case serves to produce an axial magnetic field in opposition to that produced by coil 120. The reactor may be surrounded by a lithium blanket to produce tritium or by a sub-critical fission reactor. Fig. 8 shows a circuit for operating the reactor. The gas in the reactor is initially ionised by a radio-frequency supply (not shown) applied to diametrically opposed electrodes (not shown) within the toms and circuit 121 is operated to discharge condensers 190 through coil 120. When the current through coil 120 nears its maximum, stage I circuit fires and discharges condensers 200 through shell 116; thereafter in succession stages II, III and IV operate to discharge condensers through the shell to compress and heat the plasma. In the early stages coil 135 (not shown in Fig. 8) is short-circuited and the currents induced in it promote stability of the discharge, but in the final stage the coil is open-circuited; in this final stage the plasma delivers to the circuit energy which may be used to recharge the condensers of stages III and IV. The cycle may last 0.1 second and be repeated at 1 second intervals.

Title: Continuous injection moulding
IPC: B29C39/26
Filed: 1978-05-10
Abstract: In the process, an endless, flexible metal strip (12), which encircles a casting mould wheel (10) and rotates therewith, engages in the casting mould wheel. The casting mould cavities, closing between the metal strip (12) and the casting mould wheel (10) at an engaging location (14) and opening at a releasing location (20), are filled with plastic via an injection shoe (16) through openings in the metal strip (12). After the releasing location (20), the components are removed from the casting mould cavities, the metal strip at the same time engages in the casting mould wheel (10) along an arc having a central angle (22) of less than 180 DEG , for example 110 DEG , and a large radius of curvature. This permits the use of a metal strip in which casting mould cavities are likewise formed, and which has a thickness which is many times greater than 0.001 times the casting mould wheel, without the metal strip (12) suffering from fatigue and breaking. The process is suitable in particular for producing slide fastener strips. For this purpose, carrier strips (28, 30) are introduced into corresponding recesses, for example in the casting mould wheel, are encapsulated and drawn off with the slide fastener elements from the casting mould wheel (10). <IMAGE>

Title: Improvements in or relating to carburetters for internal combustion engines
IPC: F02M17/14
Filed: 1933-07-03
Abstract: 406,557. Carburetters. LORENZEN, C., 16, Wusterhauserstrasse, Berlin. July 3, 1933, No. 18801. [Class 7 (iii).] A combined spray and surface carburetter is provided with a hollow disc-like spring-pressed valve having within it a fuel-metering needle, and, during the first part of its stroke, the valve closes the main air passage in piston fashion, but opens the fuel nozzle and an air passage disposed in the interior of the valve, to cause the carburetter to act as a surface carburetter, the valve being provided with transverse walls upon which the fuel is spread out and evaporated by the passing air. Within a casing a is mounted an adjustable choke ring g formed with a tapering interior which merges into a parallel portion adapted to house a piston valve b. The valve b comprises a hollow disc supporting a needle valve d which controls the outlet of fuel from a supply passage k. Engine suction acting past a throttle valve r draws down the air valve b, allowing fuel to flow over its ribbed upper side and air to be drawn in through ports l in the valve stem, which is adapted to slide on the fuel supply pipe k. At starting and during idling, all the mixture enters thus, but when the suction draws the valve b beyond the narrow portion of the choke tube, fuel, unvaporized on the top of the valve, is sprayed into air drawn past its edges. A diaphragm m, at the top of the carburetter, associated with a piston t, controls the supply of fuel to the fuel nozzle. The choke tube g is formed with outstanding pins engaging in inclined slots in the casing a, rotation of the tube either raising it to produce a lean mixture for fast running, or lowering it to provide a rich mixture for acceleration. The rotation may be effected barometrically. The valve b may be depressed at starting by a rod o to flood the carburetter, or the throttle lever may be adapted, when it is fully opened, to depress an arm in the air inlet for the same purpose. The metering-needle d is of straight conical form to provide relatively more fuel during the first part of the valve stroke than during the second part thereof.

Abstract: 979, 402. Web coating apparatus. ALGEMENE KUNSTZIJDE UNIE N.V. May 13, 1963 [May 18, 1962], No. 18814/63. Heading D1L. Apparatus for coating plans with lacquer comprises a lacquer tank having a vertical drying shaft connected thereto, means for transporting the film through the lacquer tank and the drying shaft, means for collecting the film, and a system for the circulation of warm air in the drying shaft, a blowing chamber, connected to a circulating system for cooling air, being provided at the top of the drying shaft below the exit guiding roller, passage of air from the blowing chamber being regulated by an adjustable constriction in the upper wall of the chamber. In one embodiment, a film 3 of regenerated cellulose is guided by rollers 4 and 9 through slit 6 in the wall of tank 7 filled with lacquer 10. The film is passed upwardly through shaft 5, past doctor rollers 11, through slit 15, and adjustable slit 14 and is removed at 13. Hot air, which enters the shaft at 16 via fan 18 is maintained at e.g. 120‹C. by circulation, at intervals down the shaft through heat exchangers 20, 23. Air is discharged at 25. Between slits 14 and 15, cooling air is blown in at 28 via heat exchange 29. From the space adjustable slit 14, air is extracted by fan 31, through line 30 and is partly blown through line for recirculation through line 28. By regulating the recirculation of air by means of valve 34 and by adjustment of slit 14, the blowing chamber formed between slits 14 and 15 is maintained at above atmospheric pressure. This enables the pressure in the shaft below slit 15 to be maintained at at least atmospheric and so prevents leakage in of cold air on to the film.
