Abstract: 1314859 Purifying I. C. engine exhaust gases ESSO RESEARCH & ENG CO 30 June 1970 [12 Feb 1970] 31540/70 Heading F1B A pulse of secondary air is injected into the or each exhaust port 4 of the engine 10 when the exhaust valve is open in an amount in the range of 10 to 30% by volume of the total volume of exhaust gas discharged. The air from a pump 30 passes through an engine-driven distributer 40 and conduits 43. Exhaust gas may be recirculated to the engine intake between the carburetter fuel inlet 11 and the throttle valve 8 through a valvecontrolled conduit 22. The control valve 21 is opened by intake manifold vacuum acting on a diaphragm 20 and the vacuum is substantially eliminated to close the valve when the choke valve 7 is closed and a valve 26 opens the vacuum conduit 27 to atmosphere and when the throttle valve 8 is set below 10 and above 90% full throttle. A valve 16 linked to the throttle valve opens the vacuum conduit 17 to atmosphere. To prevent overheating of the insulated exhaust manifold reactor 2, e. g. above 1800C., air from the pump 30 is supplied to the intake manifold 1 through a valve 52 when the exhaust gas pressure acting on the diaphragm 51 exceeds a predetermined value. The distributer 40 comprises an apertured plate (44), Fig. 2 (not shown), rotated by a shaft 46 from the engine cam-shaft or crank-shaft via a belt 41 or gear, the plate aperture (45) registering with ports 42 in the distributer casing.

Title: Holographic systems
IPC: G02F1/13
Filed: 1971-07-07
Abstract: 1353812 Holography; modulating light SIEMENS AG 7 July 1971 [16 July 1970] 31790/71 Headings H4D and H4F [Also in Division G2] A visible image of an object irradiated with sound is obtained from the resulting acoustic interference field (acoustic hologram) by scanning the field to form electrical signals representing the sound intensity pattern in the field, applying the signals to an electrically controllable nematic liquid crystal layer in a screen assembly to form an optical hologram, and directing a beam of coherent light on to the screen assembly to reconstruct an optical image of the object. In the Fig. 1 embodiment the screen assembly comprises the liquid crystal layer sandwiched between orthogonal sets of electrodes 6, 7 carried by glass plates. The serial electrical signals are applied to the electrodes so that the liquid crystal exhibits a light-scattering effect at the points of intersection of the energized electrodes. Preferably the recording time of the entire hologram is equal to or less than the relaxation time of the liquid crystal scattering state, so that the reconstructed image resolution is not degraded. Image 12 is formed by diffraction of a convergent laser beam 8 passed through the screen assembly, the scattered light and conjugate image 11 being occluded by apertured mask 10. In an alternative embodiment (Fig. 3, not shown) the electrode sets 6, 7 are omitted, the serial electrical signals are applied to the liquid crystal layer by modulating an electron beam directed at and scanned over the layer, and the laser light is directed through the layer to an aluminium backing layer and reflected from the backing layer to form the image.

Title: Improvements in or relating to rotary internal combustion motors
IPC: F02B53/00
Filed: 1945-11-26
Abstract: 602,647. Rotary engines. STEVENS, A. H. (Reynolds Metals Co.). Nov. 26, 1045, No. 31808. [Class 110 (ii)] A rotary internalcombustion engine of the rotary abutment type comprises compressor chambers 5 and engine cylinders 5<1>, all piston rotors 12, 11 being keyed to a shaft 7 and the abutment rotors 19 being supported on stub shafts 21. The latter are hollow to allow passage of cooling water, supplied by a pump, through the abutments which contain fins 20. Branch pipes 53 feed in cooling water from an external radiator. The water passes through spaces 2x and out through pipes 52. The interior of each piston 11x also has cooling passages with an inlet 60 and an outlet 61, the water being led into each piston from the hollow shaft 7, by means of a plug p. Fig. 10 shows how each piston is secured to its rotor. Packing bars 14, Fig. 27, are pivoted in each piston and pressed into sealing position by springs 15. The bars are placed in the piston tips and sides in an interlocking manner. Fuel gas from a carburetter 61<1> enters a port 63 which is closed by a flat end face of an abutment 17, which is recessed. The , gases pass into a chamber 5 and are compressed between the piston and the abutment rotor and forced through ports 67 leading to a combustion chamber. After being fired the gases drive a piston 11x and are exhausted by side ports, controlled by the abutment rotor. The shafts 25, 7 are coupled together by gears 26, 27. A water pump 35 is driven by a pulley drive 33, 34 and an ignition distributer, at the other end of the engine, by gearing. Other pumps, for oil and water, are driven by gearing, the lubricating oil being filtered. The firing of the charges occurs 180 degrees apart for balancing purposes.

Title: Improvements in or relating to electrical signal gating circuits
IPC: H03K17/52
Filed: 1954-11-03
Abstract: 782,910. Electronic counting apparatus. GENERAL ELECTRIC CO., Ltd., and BEESLEY, J. H. Oct. 27, 1955 [Nov. 3, 1954], No. 31835/54. Class 106 (1). [Also in Group XL (c)] The Figure shows a chain of gas tubes 22, 23, 24 connected in a closed ring with an interstage coupling between them comprising a coincidence gate of the type described in connection with Fig. 1 (not shown) (see Group XL (c)), the firing of any one gas tube extinguishing the others by the drop across the common anode resistor 38. Thus if gas tube 23 is fired the rise in voltage at its cathode cuts off rectifier 54 so that the voltage at the junction of resistor 41 and capacitor 44 rises to a sufficient extent so that tube 24 is fired. In the interstage coupling between tubes 22 and 23, however, the capacitor 43 is shunted by two parallel paths so that for tube 23 to be fired it is necessary not only that tube 22 should have fired but that a positive pulse should be applied to terminal 53 simultaneously. Terminal 53 may be connected to the cathode of a particular tube in a counting chain such as that described in Specification 734,875, [Group XL (c)], thus only when that particular tube of the chain is fired will the terminal 53 have a positive pulse applied to it so that when tube 22 also fires tube 23 will be triggered.

Filed: 1945-11-27
Abstract: <PICT:0604567/III/1> <PICT:0604567/III/2> <PICT:0604567/III/3> <PICT:0604567/III/4> An apparatus for coating a series of articles with liquid coating material including evaporating solvent capable of producing explosive gases, comprises means for applying liquid coating to the articles, an electrode, means for setting up an electrostatic field between the articles and electrode, a conveyer for carrying the articles into the field past the electrode and in predetermined spaced relation thereto, and means controlled by the position of one of the articles relative to the electrode before entering the field for rendering the apparatus inoperative when the article upon entering the field would so closely approach the electrode as to induce a spark therebetween.  Referring to the drawings, Fig. 1 shows a dipping trough 10 containing coating liquid through which groups of articles 11 are submerged and drawn.  The articles may be shell casings carried in groups suspended from a conveyer by hangers 12 and hooks 13.  The hangers are carried by bars 14 with ends supported by conveyer chains 15 running in tracks 16. The articles pass from the trough through an electrostatic field comprised by a high voltage electrode in the form of a wire mesh screen 20 surrounded by protective fence 21.  The screen is negatively charged through power line 20a from power pack 22 and is suspended by insulators 23 from the tracks 16.  These tracks and the other terminal of the pack are earthed. A control member such as a trip bar 25 is fixed across entrance gates 26 of fence 21 and activates switch 28 which is normally closed and opens if an article 11 strikes the bar 25, so breaking the main driving circuit and stopping the apparatus.  The switch 28 may be actuated by other known means such as a contact wire or electric eye.  Immediately below the articles 11 is an apertured air duct 32 with a blower 33, the apparatus being so arranged as to direct a forced draught of air upwards so removing any accumulation of gases given off by the solvent.  Fig. 5 illustrates an arrangement whereby a natural draught is created by passing the articles through a hood 40 open at the bottom and terminating at the top in a restricted passage 41. Specification 570,522, [Group XII], is referred to.
