Title: Improvements relating to gas control mechanism for gas fires, stoves and the like
IPC: F16K5/12
Filed: 1944-08-17
Abstract: 593,138. Igniting gas burners. EVERED & CO., Ltd., RADIATION, Ltd., and PINKESS, L. H. Aug. 17, 1944, No. 15691. [Class 75 (iii)] [Also in Group XXIX] A gas-control fitting for gasheated appliances comprises as a unitary structure, a main body or block adapted for connection to the burner of the appliance and to a gas-supply pipe, the said block housing a valve which controls the flow of gas to and from a gas governor and being formed with a passage leading to a pilot jet ignited by spark-affording mechanism of the friction or abrasive wheel type also mounted on the block and operated by the same handle which controls the valve. As shown, the fitting comprises a body or block 5 containing a plug valve 8 and having a chamber 5f in which the operative parts of the gas governor are assembled, (see Group XXIX). A pilot jet nozzle 19 is screwed into boss 5l on the block 5 and is supplied with gas by a passage not shown, when the plug is turned beyond the fully open position. The plug 8 and the spark-affording mechanism are operated by a single handle 20 mounted on the plug spindle 8g. The sparking mechanism comprises an abrasive wheel 22 on a spindle 23 mounted in lugs 24 in a bracket 24a supported on an extension 10b of a cover-plate 10, closing the plug bore 5b. The wheel 22 engages a flint carried in a tubular member 26, itself supported by a double-armed coil spring 29 on the bracket 24a. The abrasive wheel 22 has a ratchet-toothed part 22a engaged by the pawl or bent end 30a of a spring strip 30 mounted on the inner face of a bracket 31 pivotal about the spindle 23 by means of lugs 31a. The pivotal movement of the bracket in one direction is caused by a coil spring 32 and limited by a stop 24b on the bracket 24a. The movement of the bracket 31 in the other direction is effected by a box-like member 33 non-rotatably mounted on the spindle 8g. The member 33 has a channel-shaped extension 33a in which is pivotally mounted a rockable member 35 pressed by a blade. spring 36 against the cross edge of the extension 33a. The rockable member 35 moves the bracket 31 and so stresses the spring 32, whilst the pawl 30a moves freely over the ratchet teeth 22a. When the plug is moved beyond the fully open position, the bracket 31 can slip past the rockable member 35 under the action of the spring 32, the pawl 30a then engaging the ratchet teeth 22a and so causing the abrasive wheel to rotate against its flint.
Patent GB-808841-A (GB)
Title: Improvements relating to light projecting systems
IPC: H04N9/16
Filed: 1955-06-01
Abstract: 808,841. Colour television light modulating. GENERAL ELECTRIC CO. June 1, 1955 [June 1, 1954], No. 15740/55. Class 40 (3). [Also in Groups XX and XL (a)] In apparatus for producing coloured images in accordance with colour television signals, polychromatic light from a source 22 illuminates a bar and slit system 23, the slits of which are imaged on to the bars of a second system 27, and a light modulating medium 25 included in the light path between systems 23 and 27 is controlled so that each elemental area of its surface function as a diffraction grating, the arrangement being such that each elemental diffraction grating diffracts the light that passes therethrough into a spectrum having such an intensity and diffraction angle that only light of the required intensity and colour is passed by the corresponding elemental portion of the second bar and slit system 27 to form an image on screen 29. As illustrated, the medium is deformed in thickness electrostatically under the control of an electron beam from source 30, the beam being scanned in a conventional television raster by coils 35 and being additionally deflected in the line direction to produce a pattern of grating lines by a high-frequency sine wave oscillation applied to plates 34. By varying the frequency of the oscillation the spacing of the grating lines may be varied to alter the angle of diffraction whereby the spectrum shifts in relation to the slits in system 27 and a different wavelength of light passes. In Fig. 4 fixed oscillations at 14, 17 and 20 Mc/s. are produced by oscillators 40, 41 and 42 to produce gratings passing respectively red, green and blue light. The oscillations are individually modulated in amplitude by corresponding component colour television signals from sources 37, 38, 39 whereby the peak to trough amplitudes of the resulting gratings are varied so as to control correspondingly the amounts of transmitted light. Reference is made generally to the use of heat and sound to control the medium. The medium may comprise silicone oil in a liquid or gelatinous form. The medium may be controlled to exhibit the three grating patterns either simultaneously or in a sequence at field frequency. In a modified system, Fig. 6, the deformable medium is carried by a spherical mirror 44, the light from a source 53 being deflected to the mirror and returned to the projection axis to screen 55 by prisms 49 and 48 which carry the slit systems 51 and 50 on their lower faces. The electron beam deflected at 46 by signal modulated highfrequency oscillations from 57 projects through a central hole 56 and scans the mirror 44 under the control of coils 52. The Specification gives suitable dimensions for the bar and slit systems and discusses the theory of the modulation process.

Title: Improvements in and relating to Electric Precipitators and the Removal of Particle Accumulations therefrom
IPC: B03C3/76
Filed: 1968-04-02
Abstract: 1,183,432. Control systems for electrostatic precipitators. GOLD FIELDS MINING & INDUSTRIAL Ltd. 2 April, 1968 [2 May, 1967], No. 15774/68. Heading H2H. In order to maintain the operation of an electrostatic precipitator in an optimum condition the electrodes thereof are periodically vibrated to remove the accumulations of particles thereon, the intensity of vibration being made responsive to the power input to the precipitator. An electrostatic precipitator 14, provided with emitter and collector electrodes 16, 18 respectively, is supplied from an A.C. supply 10 by way of a transformerrectifier unit 12. To remove the particles, the emitter and collector are provided with vibrators 20, 24 respectively, the operations of which are controlled by thyristor devices 60E, 60C, each of which is energized from power sources 58E, 58C for predetermined time intervals by means of timers 62E, 62C. A signal representing the input power to the precipitator is derived by means of a current transformer 32, rectified and filtered by units 34. 36 respectively. The signal thus obtained is amplified by amplifiers 40E, 40C, and provides energization for windings 52E, 52C of magnetic amplifiers 50E, 50C, these amplifiers further being provided with bias windings 54E, 54C. The outputs of the magnetic amplifiers are used to gate the thyristor devices and so control the intensity of vibration of the emitter and collector electrodes. The windings 52E and 54E are arranged to oppose one another whilst the windings 52C and 54C assist each other. Thus the intensity of vibration of the emitter is inversely proportional to the input power to the precipitator whilst that of the collector is directly proportional thereto. The control systems are each provided with limit and gain controls whereby to limit the intensity of vibration of the electrodes and to control the rate of change of such intensity with given changes in input power to the precipitator.

Title: Catalytic cracking process
Filed: 1941-12-17
Abstract: 570,327. Cracking oils. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. Dec. 17, 1941, Nos. 16298 and 16299. Convention dates, Dec. 17, 1940, and Sept. 12, 1941. [Class 32] Heavy oils boiling in the range of gas oils are cracked by fractionating the oil into a light gas oil, i.e., an oil at least 90 per cent. of which distils below 700‹F. and a higher boiling fraction and subjecting the fractions separately to catalytic conversion the heavier fraction being heated to at least 30-75‹F. higher than the light gas oil fraction which is treated at a lower feed rate per volume of catalyst than the heavier oil. The cracked products are fractionated in a common fractioning tower to separate light and heavy fractions which are recycled to the corresponding conversion zones. The light oil is preferably heated to 850‹F. and the heavy oil to 900 ‹F. Catalysts may be used in suspensions or as stationary beds. A heavy crude oil is preheated in coil 14 and passed into a fractionating tower 24 where it is fractionated into (a) gasoline taken overhead through line 34 (b) a light gas oil collected on tray 32 (c) a heavy gas oil collected on tray 28. The light gas oil is fed through line 111 and heating coil 102 to catalytic conversion chambers 118, 145 while the heavy oil is similarly fed through vaporising coil 56 to conversion chambers 66, 130. The products from these conversions are passed to fractionating tower 76 from which gasoline is recovered overhead while light and heavy fractions are collected on trays 94 and 82 respectively and recycled to the corresponding heating coils 102, 56. The duplicate cracking chambers are used alternatively so that one may be regenerated in the usual manner while the other is on stream.

Title: Anti-skid device, particularly for fluid pressure operated aircraft brakes
IPC: B64C25/46
Filed: 1958-05-21
Abstract: 831,703. Anti-skid brake control. BENDIX AVIATION CORPORATION. May 21, 1958 [June 26, 1957], No. 16364/58. Addition to 780,025. Class 103 (1).  In an anti-skid device for controlling fluid pressure operated aircraft brakes of the kind described in the parent Specification, the flywheel 16 is driven through shaft 14 by a wheel 12 adapted to contact the rim of an airplane wheel. The drive is through a collar 24, attached to shaft 14 by screws 25, drive pins 26 and driven plates 28. It is arranged that the coupling between collar 24 and driven plate 28 is dependent on the engagement of the hook end 60 of a pivoted latch member 52 engaging a latch pin 62 on the member 24. By an arrangement of springs 34 and 50 and fly-arms 48, it is provided that if the speed of rotation of the aircraft wheel is below a predetermined rate, the latch member engages with pin 62 so as to prevent angular movement of the fly-wheel 16 with respect to shaft 14. In this way, if for instance, the aircraft does a bounce landing and the wheels tend to lock, due to the brake pressure applied, the wheel deceleration will require the anti-skid device to cycle and reduce the brake pressure. During this time a priority valve 98 maintains sufficient pressure in chambers 92 connected to the brake cylinder, to ensure a certain amount of deceleration of the wheels while it is airborne. As the wheel speed drops, the fly-bars 48 and latch 52 return to a position which prevents the fly-wheel 36 closing. .The rotary brake releases valve 18 which controls the passage of fluid out through reservoir return port 106.
