Title: Improvements in or relating to gas cleaning
Inventor: HEINRICH DIETER OTTO
IPC: B01D46/04
Filed: 1964-06-27
Abstract: 1,098,189. Electrostatic separators. LODGE-COTTRELL Ltd. June 18, 1965 [June 27 1964], No. 26705/64. Heading B2J. Gas cleaning apparatus for use in an electrolytic aluminium manufactory comprises gas filter units 22, Fig. 1, and a carriage 24 with collecting means and rappers 21 which travels to collect filtered material from the units in a sequence. As described, banks 20 of electro static filters 22 are provided wherein the particles are charged to a high potential in the first stage, and in a second stage are caused to migrate to a collecting surface. The filter units 22 are arranged for upward air flow in straight horizontal rows. The filtered dust is collected simultaneously from the filter units of a set which comprises one unit of each row. The carriage 24, which has magnetic disc brakes, is driven along rails 32 by an electric motor 33, and comprises three hopper sections 34 with lower portions 37 each closed by a slide valve which is operable to empty dust into a stationary storage hopper 26. The carriage also includes in each hopper section opposed motor driven doors 48 Fig. 3, which are closed when the carriage is travelling, and when opened also operate telescopic mouthpieces 36 of an upper portion 35 of the hopper sections 34. The rapping mechanism 21 comprises three sets of reciprocatory hammers 62 spaced along a spindle 64 which is reciprocated by linkage and a cam device 90 driven by an electric motor 107, Fig. 4. In operation, manual operation of a pushbutton releases the disc brakes and starts the carriage drive motor 33. so that the carriage travels past the filter units until it reaches an end stop, whereupon the brakes are applied and the drive stopped. The carriage is then returned by an automatic circuit until it energises a striker which stops the motor, applies the brakes, opens the doors 48, raises mouthpieces 36 of the hoppers into engagement with the filters, cuts off the power to the filter units and operates the rapping mechanism. After a preset time, the rapping unit stops, and the units 22 are reconnected to power, with five power pulses applied to prevent sparking. The doors are then closed, the mouthpieces lowered, the brakes released and the carriage moves until it engages another striker at the next position. The process is repeated until all the banks of units have been emptied, when the load is delivered to the storage hopper 26, by manual operation of slide valves in the hopper sections 34. The apparatus remains in its rest position until manually restarted. In modifications, all controls may be manual, and the rappers may be replaced by brushes, scrapers, or air blasts; gas flow may be horizontal, or inclined; and sealing of the mouthpieces may be by an inflated tubing, inside the mouthpiece, or by arranging for the doors to move against the side walls of a filter unit directly with the remaining sides sealed by a partition wall with a rubber seal on top.

Title: Improvements in or relating to spark plugs and method of making same
IPC: C04B37/02
Filed: 1949-10-18
Abstract: 674,002. Uniting metals to ceramic materials. STACKPOLE CARBON CO. Oct. 18, 1949 [Dec. 8, 1948], No. 26727/49. Class 36. [Also in Group XXVII] A method of making a sparking plug comprises applying titanium hydride to predetermined areas of the inner and/or outer surfaces of a tubular ceramic insulator 1 near its inner end and then soldering the centre electrode 9 to the inner surface of the insulator and/or the plug casing 4 to the outer surface of the insulator, depending upon which surface or surfaces has or have been coated with titanium hydride; the plug may embody titanium hydride soldered bonds 16, 17, joining the insulator to both the electrode 9 and casing 4, respectively; the insulator 1 may also have an internal shoulder 3 to which a head 11 on the electrode is joined by the titanium hydride soldered bonds. The insulator 1 has a stepped through bore 2 in which is formed the shoulder 3 that supports the head 11 of the centre electrode 9; the upper bore part contains a suppressor and a coil spring in order to connect the centre electrode to a terminal in the outer end of the insulator. Titanium hydride 16, either in the form of powder or paste is deposited on the surfaces to be joined after which silver or copper based solder or pure silver or copper is then applied to the titanium hydride coatings and the plug is subjected to a temperature of approximately 1000‹ C. to firmly unite the parts so coated. The solder may be mixed with the titanium hydride and the mixture applied in one operation to the several surfaces; the heating is effected in a furnace either filled with hydrogen or in which a vacuum has been created. When hydrogen is used the moisture content of the furnace is reduced to a minimum by use of a drying agent, such as aluminium oxide, and the hydrogen is passed through a palladium catalyst in order to change its oxygen content to water. Different plugs may have different areas of bonding in order to vary the heat transfer from the plug to the engine cylinder block. Specifications 625,371 and 626,992 are referred to.

Abstract: 1,029,655. Binaural systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 25, 1962 [July 25, 1961], No. 26813/61. Headings H4J and H4R. A circuit arrangement comprises two audiofrequency signal channels X, Y (Fig. 2), one of which has two identical non-interacting attenuating circuits A1, A2 and each of which includes a phase-shifting network P or Q. The phaseshift of signals passing through channel X is substantially identical with the phase-shift of signals passing through channel Y. The signals are stereophonically related audio-frequency signals, " difference " signals being fed to channel X while " sum " signals are fed to channel Y. Attenuators A1, A2 and phaseshifting network P are isolated from one another by buffer amplifiers B and identical amplifiers B are provided in channel Y. Attenuators Al, A2 may attenuate either high or low frequency components. Thus signals above 700 cycles per second may be attenuated in order to improve the apparent location of a sound source when the signals are applied to spaced loud-speakers. Alternatively, lowfrequency attenuation may be used in stereophonic disc-cutting equipment in order to reduce the vertical excursion of the cutter stylus.

The open ends of each tube are flattened and sealed. A baffle 8 of V-section is disposed inside each tube and has holes 9 which increase in size with distance from the point of gas entry and which are arranged equidistant from adjacent burner orifices 2. The Provisional Specification states that a round burner is formed from a circular sheet of metal. The U-ridge is formed by cold drawing to approximate dimensions, the burner orifices are then punched or drilled and finally the ridge is formed to exact dimensions. The Provisional Specification also states that in a burner of ovoid shape the ridge may be formed by hydraulic pressure. U.S.A. Specification 2,015,822 is referred to.
