Abstract: A device for producing alternating electric current of high frequency for power consumers such as fluorescent tubes (Ly1, Ly2) comprises a transformer with a winding (n3) connected in series with an output terminal (e) and active electronic components such as transistors (T1, T2) controlling the output current, the transistors being controlled by electric voltages produced by inductive feedback in feedback windings (n11, n12). Magnetic saturation is utilized to modify the inductive relationship in such a way that the transistors (T1, T2) cyclically change the direction of the output current. The feedback takes place in two magnetic cores (Tr1, Tr2) of the transformer, each core being provided with at least one further electric magnetization winding designated a command winding (n5, n6) as electric current is fed through the command windings to control magnetic saturation of the magnetic cores (Tr1, Tr2). As a result, combined control of the frequency and of the active electric power in the fluorescent tubes (Ly1, Ly2) is possible so that the luminous power may be controlled over a wide range while suitably high voltages can be maintained to ignite the tubes properly.

Abstract: The invention relates to a process for manufacturing a multi-layer, preferable twin-layer composite of a polystyrene foam film and a coextruded unfoamed film, especially for further processing into labels or mouldings making use of the shrinking capacity of the films, in which a polystyrene material is extruded together with nitrogen as the blowing agent and a pore former from the nozzle (16) of an extruder (2) and the extruded material is blown below the softening point before cooling. In order to produce polystyrene foam film which is as aging-resistant and easily printed as possible with the greatest possible saving in material and as reliably as possible, the invention proposes that 1/30 to 1/50 nitrogen (measured in NL) of the weight of the film (expressed in grams per square metre) be used as the blowing agent per kilogram of foam film, together with a powdered mixture of sodium bicarbonate and citric acid, and that the rigidity/surface quality of the film be controlled by the blowing ratio.

Abstract: A method for producing fibrous monocrystals, i.e. whiskers, of high-temperature superconductive ceramics in their best superconductive crystal directions, thereby in the main avoiding the production of non-superconductive fibres and also the effect which decreases the superconductivity due to relatively weak superconductive crystal directions. Whiskers are produced by means of physical gas-phase coatings (physical vapour deposition = PVD), for example using radiofrequency magnetron sputtering (RF magnetron sputtering) or by means of chemical gas-phase coatings (chemical vapour deposition = CVD). The growth underlayer, i.e. the substrate, employed is a ceramic monocrystal surface in accordance with the (100) orientation, a ceramically coated metal surface or a smoothed or polished metal surface. It is typical of the latter alternative that the coating which is formed on the metal surface initially grows in a relatively weak superconductive crystal direction but then alters its growth to the best superconductive crystal direction and is at the same time transformed into whiskers.

Abstract: A retention device (10), particularly useful for drainage tubes and the like, having a pad (11) for adhesive attachment to a patient's skin at the exit/entry site for a post-surgical drainage tube. The device includes a retainer body (13) secured to the pad and provided with a strap (14) to be looped and tightened about the drainage tube for immobilizing that tube. A passage in the body receives the free end of the strap and a latching mechanism (28) prevents retraction of the strap unless a pair of side flanges (26) of the body are squeezed towards each other to alter the configuration of the body's top wall (27) and cause upward disengagement of a restraining pawl from the ratchet teeth of the strap. In one form of the invention, the strap is oriented horizontally and the passage is spaced well above the pad so that the horizontal plane of the passage substantially bisects the loop along its axis, thereby allowing portions of the loop to be located above and below the entrance to the passage. In another embodiment, the strap is oriented in a vertical plane and the pawl is cammed laterally and upwardly to disengage the strap when the side flanges are squeezed towards each other. <IMAGE>

Abstract: 157,152. Hiorth, K. A. F. July 2, 1915, [Convention date]. Effecting chemical reaction between gases under pressure; ammonia, catalytic synthesis of; catalytic apparatus.-For gas reactions which require high pressure, e.g. the catalytic synthesis of ammonia, a valveless reaction chamber is employed, into which the gases are compressed by utilizing the inertia of a flowing liquid. The reaction chamber C, provided with valved inlet and outlet pipes F, G for the gases, communicates through a pipe D having a non-return valve E with the tube A, in which liquid flowing to the outlet B can be checked by closing the valve H. In operating the apparatus, the reaction gases are admitted by pipe F to the chamber C; the valve H is then closed, whereby the liquid is forced into the chamber C to a level which covers the gas inlet and outlet pipes F, G; finally, the valve J is opened after the reaction is completed for the removal of the products, and valve I is opened for the admission of fresh quantities of the reacting gas. If desired, the gases may be compressed to a certain extent before introduction into the chamber C, such compression being produced, for instance, by means of a turbine driven by the liquid discharge from the tube A.

Title: Method of and apparatus for forming a workpiece
IPC: B21K1/46
Filed: 1975-12-09
Abstract: 1493671 Forging PLESSEY CO Ltd 9 Dec 1975 [10 Jan 1975] 1045/75 Heading B3H A method of hot forming an elongate metal workpiece comprises engaging the workpiece with a pair of dies 2, 4 and 36 or 73, passing a pulsating electric heating current through the workpiece, discontinuing the supply of current to the workpiece when it has reached at least the forming temperature, and moving the dies relatively to each other or to one or more other dies so as to carry out the hot forming. A workpiece is released from a hopper (not shown) into a shoot from which it passes to a work area 74. A block 54 is lowered until a roll 58 rests on a flat portion 60 of the block so that a die 73 is moved up to the workpiece and acts as a backstop for it. The workpiece is pressed on a die 36 which is held in position by a roll 26 bearing on a flat portion 29 of a block 22. A pulsating current is then passed through the dies 2, 4 and 73, which are all grounded and act as one pole, and the die 36, which acts as the other pole. The current may be controlled by ignitions interrupting the primary circuit of a transformer and the die 36 should be firmly in contact with the workpiece before applying the current. When the required temperature has been reached, the current is interrupted and the die 36 moved away. The workpiece is allowed to heat soak to attain an even temperature and the heating process is repeated as necessary. The dies are water cooled and may create cold spots. When the workpiece is at the required temperature, the block 22 is lowered, moving the die 36 towards the workpiece and forming its head in a forming aperture 38. After forming, the dies 36, 73 are retracted, the die parts 2, 4 separated and the formed workpiece ejected into an outlet shoot. In an alternative arrangement a single piston and cylinder arrangement may be provided to move both blocks 22, 54.

Title: Self-adjusting cushioned vehicle coupler arrangement
IPC: B61G9/16

Abstract: 1,083,721. Combined buffing and draw gear. J. KIRSCH. Jan. 11, 1965 [Jan. 15, 1964], No. 1095/65. Heading B7T. A centre sill 12, Fig. 1, cut off at 16 and cut away at the sides 18, has a part 44 to which is welded along ribs 61 a housing 20 so as to close off the top. The housing, which is provided with a bottom plate 28, is shaped to provide limit stops and guide an adapter 24 slidable therein and mounting a coupler 26. An hydraulic shock-absorber 32 secured by blocks 114 to the side walls 46 and supported with the plate 28 on beams 118, Fig. 3, is actuated by a rod 30 mounted at each end in spherical bearings in the adapter and a piston within the cylinder 116, Fig. 2 (not shown). The rear end of the cylinder 116 has an outlet port 140, Fig. 3, connecting with a conduit 34 which is flanged to a hydro-pneumatic accumulator 38 and is throttled at 150. The accumulator 38 comprises a free piston 170 movable against high pressure nitrogen charged into the chamber 166, and bolted beneath 38 is a valve unit 42 containing a slide valve 244 and a free piston 192 moving against a low pressure gas in chamber 198. The slide valve has equal oil pressure areas 268 and 266, and an end area 270 which is acted upon by oil in 196 when the valve is closed, Fig. 6. The duets 206, 210, 208, 212 and the chambers 172, 196 are all filled with oil. In operation, on low impact as, say, in coupling up, the adapter 24, the rod 30 and piston 132 are moved rearwardly to force oil out of the chamber 136 into the pipe 34 and the passage 148 where it is throttled by the restriction 150. This metered oil flow absorbs energy and a difference of pressure is created on opposite sides of the restriction 150. This difference of pressure acts to move the slide valve 244 to the right so that the valve head 254 engages the valve seat 264 and closes off the passages 208, 212 from the chamber 196. The piston 170, however, is not moved on light impact. As the impact force reduces, an oil pressure balance is created in the passages 148, 152 and in the passages 206, 210, 208, 212 so that equal forces on the piston areas 266, 268 balance each other. Under these conditions the low oil pressure on the piston area 270 lifts the valve off its seat 264, thus again opening up the chamber 196. On low impact the energy is absorbed as described above, the valve remains off its seat and the piston 192 pressed by low gas pressure causes a return flow of oil. On high impact forces, the operation is as described above but when the valve is moved off its seat a pressure differential is re-created and the valve is caused to close again and then hunt until the energy has been absorbed, the piston 172 being pushed back to delay hunting and causing oil to pulse into chamber 196 and push piston 192 back in steps. If at any time the pressure in the unit 32 reaches danger level then a pressure relief valve (182), Fig. 4 (not shown), operates to allow the high pressure oil to flow into a duct 184 (see also Fig. 6) and into the chamber 196.

Abstract: 867,001. Liquid piston engines. SHAUGHNESSY, T. W. Sept. 25, 1959 [Jan. 12, 1959], No. 1131/59. Classes 7(2) and 7(6). [Also in Group XXVI] In a fluid drive engine the hollow pistons 7 force hydraulic fluid through a drive shaft 2 to the interior of a turbine wheel 3, the escape of the fluid from which through outlets 14 causes rotation of the wheel 3 and shaft 2. The hydraulic fluid escaping from the wheel 3 returns through passage 4 and is returned to the spaces beneath the pistons 7 by a screw pump formed on the shaft 2. The pistons 7 are hollow so that gas is trapped therein above the surface of the hydraulic fluid, which gas is compressed on the downstroke of the pistons and assists their return on the upstroke. The cylinder inlets 9 and outlets 8 are controlled by a sleeve 18 which is moved downwards by the piston and upwards by the hydraulic fluid.

Abstract: 1528642 Bobbin changing in open-end spinning W REINERS VERWALTUNGS-GmbH 13 Jan 1976 [17 Jan 1975] 01168/76 Headings DID and D1J In a multi station open end spinning machine when a full take up bobbin is produced a travelling bobbin changer 35 is signalled and the work station 11 is stopped, the bobbin changer being provided with a joining bobbin 68, 138 from which a thread end is carried by a guiding element 57 to the spinning device 12 which is then re-started, the newly spun thread being fixed to an empty bobbin tube supplied by the bobbin changer and the thread from the joining bobbin 68, 138 being separated. As shown in Fig. 1, the changer 35 is stopped by a rod 38 which operates a switch 40 on the changer when extended by a signal from a bobbin size sensor 119. The bobbin carrying arms 25 are released and the bobbin is pushed by arm 53 onto a surface 112 down which it rolls to a conveyor 113. An empty bobbin tube 133 is then carried to the arms 25 by an arm 95. The guide arm 57 then carries the joining thread end retained by a clamp 60 to the spinning device 12 by drawing thread from a large thread store 70. At the same time a small thread store 71 accumulates a short thread length which is subsequently released to be sucked into the spinning rotor 13 and re-start spinning. As new thread is spun, guide arm 57 returns carrying the new thread past the empty bobbin tube end where it is clamped by the carrying arms 25 and returning most of the joining thread to the large store 70. Meanwhile a guide 47 has been extended and deflects the new thread to a thread catching end of the empty bobbin tube. Cutters 106 and 101 now separate the joined section of yarn which is removed by a suction nozzle 121. In an alternative embodiment. Fig. 6, a smaller thread joining bobbin 138 is employed which is mounted on the thread guide arm 141. This dispenses with the need for the large thread store. The small thread store 142 is provided by an arm. 144 which cooperates with two guides 139, 140 on the thread guide arm 141.
