Title: Bearing assembly and supporting method
IPC: F16C33/10

Abstract: 1455500 Bearings; fluid magnetic springs LITTON INDUSTRIES Inc 28 Nov 1974 [7 Jan 1974] 51665/74 Headings F2A and F2S A support assembly comprises an element 12 and an element 14 having respective surfaces 36, 16 which define a substantially closed zone 30 containing a magnetizable fluid 26 which is maintained within the zone by a magnetic field established at a sealing gap 31 by a permanent magnet 18 with associated polepieces 19, 20 and which is pressurized by the action of a moving magnetic field produced by electromagnetic coils 33 and (22) Fig. 1 (not shown). The pressure generated in the fluid is sufficient to counteract the weight or other pressures imparted by element 12 on element 14 or vice-versa, and also offers shock absorbing characteristics. If there is to be significant relative rotary movement between the elements 12 and 14, as in a bearing assembly, the coils (22), 23 are arranged to produce a field rotating about the axis 24 of the assembly rotor, and at least one of the surfaces 16 and 36 is provided with guide portions, e.g. pockets, spiral grooves, or an eccentric rotor/stator mounting arrangement (Figs. 1, 3, 4, 5 and 7, not shown), which orientate the pressure in a direction having a component towards the centre of rotation 24. A journal bearing arrangement is described with reference to Fig. 6 (not shown). In another embodiment the coils are located around a conduit leading to the zone between the elements and are energized in a manner such that the magnetized fluid is urged into the zone through the conduit thereby pressurizing the zone as required (Fig. 8, not shown).

Abstract: 1391927 Warp knitting machines W REINERS VERWALTUNGS-GmbH 9 Nov 1972 [12 Nov 1971 28 April 1972] 51884/72 Heading D1C A warp knitting machine has a device for incorporating unknitted weft threads which includes a pneumatically actuated projectile, guided in a tube, for drawing thread from a supply across the machine. A single tube, or several arranged in a circle and rotatable about a central axis, may be provided. In an embodiment of the latter type several tubes 11 extend between rotatable discs 38, 38'. They communicate with a central air tube 8 via sleeves 9 and tubes 10. A closefitting projectile 12 is provided in each tube and has an extension 13 carrying thread holders 14. The extension passes through a slot 28 extending the length of the tube and closed by a seal 29. The projectile is drawn along the tube 11 by applying suction at the tube 10 towards the far end of tube 11. Once the projectile has passed the tube opening it is braked by the still continuing suction. At one end the holder jaws are opened to take yarn, which is cut when the projectile reaches the other end. The thread is then placed in the needle hooks by feeders 19. In an alternate embodiment, Figure 16, a single projectile 107, entraining four yarns 111-114 is drawn along a stationary tube 125. Braking at the end of the traverse is assisted by a mechanical brake 163, 164. Insertion hooks 155-158 place the yarns on disc stores 101, 101' which carry the yarns towards the needles. The yarns are held adjacent the discs, while the projectile traverses, by levers 150.

Title: Strip temperature control system

Filed: 1974-12-11
Abstract: 1492578 Cooling rolled strip GENERAL ELECTRIC CO 11 Dec 1974 [11 Dec 19731 53579/74 Heading B3M A rolled strip is cooled at a predetermined rate as it passes from the finishing train 22 of a rolling mill to a coiler 26 by controlling the number and distribution of sprays 32 which act on the strip. Since the sprays each produce a constant output, their cooling effect on the strip is controlled by regulating the number and positions of the sprays which are operative at any moment. A computer 40 selectively makes them operative according to the inputs from pyrometers 42, 44 and 46 and a pulse tachometer 54 (indicating strip speed). The pyrometer 42 serves to indicate an initial spray pattern, whereas the pyrometers 44 and 46 provide feedback signals to generate the desired strip cooling rate and coiling temperature.

Title: Regulator with balancing piston
IPC: G05D16/06
Filed: 1966-11-30
Abstract: 1,139,058. Fluid pressure control valves &c. AMERCON CORP. 30 Nov., 1966 [18 Aug., 1966], No. 53698/66. Heading F2V. An apparatus for regulating and controlling the gas pressure in a pipe comprises an inlet chamber 12 and, separated from it by a wall 15, an outlet chamber 14, there being disposed within an aperture 72 connecting these two chambers a valve closure member 21. A rubberlike diaghragm, contained within a housing 25, is on one side acted upon by a spring 43 whose compression may be varied as by nut 46, and on the other side is connected through a hollow shaft 22 to the closure member 21. Disposed below the outlet chamber, and connected to it, by means of aperture 88 and channel 18, is a syphon chamber 16, with a balancing piston 85, extending from the lower end of shaft 22, engaging by its lateral walls 87 a gas permeable felt sealing ring 89 disposed within the aperture 88. If no gas is discharged from outlet duct 13 the pressure within it builds up and this is transmitted through the channel 18, syphon chamber 16 and hollow shaft 22 to the underside of diaphragm 30 so overcoming the force due to the spring. As a result the diaphragm and shaft rise thereby bringing the closure member into contact with its seat 73. As pressure within duct 13 is reduced so the upward force on the diaphragm is reduced and consequently, the valve member 21 is lowered and the inlet and outlet chambers are brought into communication with one another. The force of the spring acting on the diaphragm 30 does not decrease linearly with the lowering in position of the closure member and this is compensated for by a gradually increasing downward force acting on piston 85, the increase in this force being a consequence of an increase in gas speed flowing past channel 18.

Title: Semiconductor electroluminescent devices and to methods of making them
IPC: H01L23/482
Filed: 1972-12-01
Abstract: 1398006 Electroluminescence WESTERN ELECTRIC CO Inc 1 Dec 1972 [2 Dec 1971] 55498/72 Heading C4S [Also in Division H1] The PN junction of an electroluminescent diode is passivated by an insulating layer formed by proton bombardment of the semi-conductor surface, the layer also acting to bond overlying beam leads to the semi-conductor surface. The first step in making a typical diode is to deposit a tellurium doped N-type GaP layer 50 Á thick by liquid epitaxy on a high resistivity GaP substrate. A hole is etched in the layer to a depth of 25 Á using a mixture of hydrogen peroxide and sulphuric acid and a layer of zinc doped P-type GaP epitaxially grown to fill the hole, after which the surface is etched or polished to remove this layer from around the hole. Alternatively a P region is formed by ion implantation or masked diffusion. Metal contacts consisting of gold doped with beryllium and silicon respectively are vapour deposited or sputtered via masking on the P region and N- type layer and heated to 600 C. for 5 minutes to establish ohmic contact. These contacts mask the underlying material in a subsequent bombardment with 300 keV protons at a dosage of 4 x 10<SP>14</SP>/cm.<SP>2</SP> which produces an insulating layer of 8 x 10<SP>13</SP> ohm cm resistivity. If heavier dosages are used the body is subsequently annealed to render it transparent again. Beam leads are next formed by masked deposition of chromium which is electroplated with gold to a thickness of 10 Á Alternatively thin layers of chromium and gold are deposited overall and holes etched in them to accommodate the metal contacts. Gold is electroplated on after bombardment and unwanted parts of the thin layers removed by etching. The wafer is then trimmed to shape by cutting with a slurry saw and etching. The device may be one of an integrated array of devices formed from a common wafer and interconnected by beam leads. In an alternative form the PN junction is situated in a mesa.
