Abstract: 1,159,230. Injection moulding. GENERAL MOTORS CORP. 8 Aug., 1968 [25 Aug., 1967], No. 37822/68. Heading B5A. A method of injection moulding a fibre reinforced synthetic resin article comprises the discharging of short length fibres in a continuous and uniform stream from a vibrated bowl and mixing the stream with a continuous and uniform stream of heat plasticizable resin powder fed from a second feed bowl, passing the mixture to a plasticizer from which it is injected into a mould. In Fig. 2 glass fibres are fed to a trough 46 of a vibrated bowl 42 and fall as a stream into a shoot 48 where they mix with a stream of polystyrene powder fed from a trough 60 of a vibratory bowl 56, and the mixture passes to an inlet 50 of a plasticizer 52. In a modification the two materials are fed from inner and outer vibrated bowls and pass upwardly therefrom along helical paths to separate outlets from which they flow as streams to an inclined shoot and from which the material falls to a plasticizer inlet. The fibres may alternatively be of nylon, rayon, sisal, hemp or jute, and the powder of polyurethane, polypropylene, polyesters, nylon, or styrene-acrylonitrile copolymer.

Title: Process and apparatus for the production of inert gases
IPC: C01B21/04
Filed: 1962-10-12
Abstract: Inert gas substantially free from oxygen and oxides of nitrogen is produced by burning substantially completely a vaporous or gaseous hydrocarbon with air at a temperature of less than 800 DEG C., cooling the burnt gas, and recycling the major proportion thereof to the combustion zone in admixture with the air for combustion. The hydrocarbon may be propane or butane.  The burnt gas may be cooled to 400 DEG C.  Two-thirds of the burnt gas may be recycled. The pressure in the combustion zone <PICT:0964846/C1/1> <PICT:0964846/C1/2> may be maintained constant by a pressure valve in the burnt gas outlet conduit.  The hydrocarbon and air may be fed to the combustion chamber at the same temperature.  The combustion chamber may comprise a gas burner (Fig. 1) or a bed of oxidation catalyst (Fig. 3, not shown).  In the former case, residual oxygen may be removed from the burnt gas by oxidation of residual and/or added hydrocarbon by catalysis.  Preheating before catalytic reaction may be effected by an auxiliary burner or a heating element.  As shown, air is forced by a fan 1 through a temperature equaliser 3, annular passage 7, and slits 4a into a combustion chamber 6 where it burns hydrocarbon admitted via pressure reducer 2, temperature equalizer 3, and gas ring 4.  Cooling of the burnt gas is effected by a water-cooled coil 9.  Most of the burnt gas is recycled via valve 11, fan 10 and annular passage 7.  The remainder is mixed with a secondary stream of hydrocarbon through a line 12 and is passed through a catalytic reaction chamber 13 and a pressure control valve 16.  Substantially pure nitrogen may be produced by removing water vapour and carbon dioxide from the inert gas.

Title: Method fo treating oil-impregnated bearings

Abstract: 1,017,658. Bearings. BOUND BROOK BEARING CORPORATION OF AMERICA. Sept. 30, 1964 [March 31, 1964], No. 39886/64. Heading F2A. In a method of treating oil-impregnated sintered bearings to render them noiseless, the bearings are immersed in a liquid medium of low viscosity, high volatility and low solvency, all with reference to the oil with which said bearings are impregnated, and are then subjected to the action of ultrasonic impulses to remove interstitial free particles of metal powder from which the bearings are formed. The medium is a petroleum aliphatic solvent having a Kauri Butanol value within the range of 25 to 50 and an A.S.T.M. distillation range of no more than 40 F., is continuously being filtered and may have an immersion temperature of 150 F. The ultrasonic impulses were within a range of 30,000 to 35,000 cycles per second for a period of three to five minutes. Filtering was by passing the solvent through a 10-micron filter, the bearings were dried by evaporating the solvent therefrom at ambient temperature, the drying time being from five to ten minutes.

Title: An electrical angle measuring instrument
IPC: G08C19/48
Filed: 1963-10-11
Abstract: 1,058,646. Phase angle measurements. E. RICE and S. HANDELMAN. Oct. 11, 1963, No. 40316/63. Heading G1U. An instrument for measuring the electrical angle of a rotating transformer such as a synchro 36 having a primary winding 38 and secondary windings 40, 42, 44 incorporates a bridge 10 having impedance arms 53, 54, 56 and input terminals 58, 60, 62 to which the outputs of the secondary windings of the synchro are connected. A pair of contacts 64, 68 are connected to the bridge arms, and at least one of these, 68, may be stepped along the bridge arms by equal increments to obtain an approximate null in the output voltage of the bridge taken between the contacts 64, 68, the position of the contact 68 being indicated by its control 74. The bridge output voltage is taken from a potentiometer 12 and compared with a reference, which may be varied by means of a potentiometer 18. Arrangements are provided so that the full voltage across the potentiometer 18 may be adjusted to correspond to the change in output voltage taken from the potentiometer 12 as the contact 68 advances one step (not through the null). The comparison between the bridge output voltage and the reference is performed in a transformer 16 whose secondary output voltage is fed to a filter 26 and phase detecter 28 where it is compared with the input voltage to the reference potentiometer. The wiper 18a is adjusted by means of the control 78 so that a balance is indicated on the meter 34. The sum of the readings on the controls 74 and 78 then indicates the required phase angle. A particular electrical angle # at which the synchro rotor may be set is transmitted from the stator windings as a particular combination of three voltages whose phases depend on #. These voltages are approximately balanced in the bridge 10, the setting just below balance being found by observing the meter 34. The bridge output voltage in this position is proportional to the angular difference between the balance point and the setting of the bridge, and this output voltage is measured by comparison with a reference, as outlined above. The resistors 70 which differ in value are included in the bridge output lead so that by adjustment thereof the bridge output voltage at the point 76 may be adjusted to be the same for the same angular change represented by a given movement of the wiper 68 over different parts of the tapped resistor 54. Detailed calibration and setting up arrangements are described in the Specification, and the invention may be applied to resistors and other electrical devices having different numbers of secondary windings, by adjusting the number of bridge arms to correspond.

A parallax panoramagram is produced by taking a series of separate pictures with a camera which is moved so that its optical axis is kept directed at the centre of interest of the scene while the light-sensitive material is moved along a straight line, and then projecting the pictures in turn on to a sheet of photosensitive material placed behind a lenticulated screen by means of a projector which is moved along a line parallel to the screen while its optical axis is kept trained at the same point. As shown in Fig. 1, the camera 1 is movable along a base 6 on which is adjustably mounted a rod 14 on a pivot 15. By engagement with the rod 14, a pin 13 on a wedge 11 arranged for movement along a guide 12 as the camera is displaced laterally causes the camera lens holder 7 to be displaced along a guide 8 so that the camera axis is displaced relatively to the film 2. Alternatively the wedge device may be replaced by a pivoted lever having a pin 13 on one arm engaging the rod 14 and on the other arm a gear sector engaging a rack on the lens holder or a pin and slot connection with the lens holder. Other arrangements are also described employing racks and threaded members for effecting the displacement of the camera axis so that it is always directed at the same point. In a further arrangement (Fig. 10, not shown), the camera is supported on a carriage movable along rails perpendicular to the central direction of the camera axis and the camera is pivoted so as to be directed always at the object by a rod pin- and-slot connected to the camera and having a roller which engages an inclined ramp. Similar arrangements to those used for taking are employed for projection printing the pictures on to a light-sensitive surface covered by a lenticular screen.
