Title: Improvements in electrostatic gas filters
IPC: B03C3/74
Filed: 1963-09-26
Abstract: 1,047,756. Electrostatic precipitators. A. RAMMELMEYER. Sept. 26, 1963 [Sept. 26, 1962], No. 37952/63. Heading B2J. An electrostatic gas filter has precipitation electrodes 1 which can be arranged to rotate or reciprocate continuously or periodically and scrapers 2 disposed inside a dust extractor duct 3, the side walls of which shield the scrapers from the gas stream while allowing the electrodes to pass therethrough. As shown, perforated precipitation electrode plates 1 are mounted on a shaft 11 in a vertical-flow gas filter and arranged to be rotated through the duct 3 preferably of heat-resistant plastics material in the direction of the arrow in Fig. 2, the scrapers 2 serving to heap up the dust and pass it through the perforations to the compartment 4 below; alternatively the scrapers may be attached to the opposite wall of the duct but still pointing in the same direction and the direction of rotation reversed. The scrapers, preferably of steel, bronze or heat-resistant plastics material, are made individually adjustable towards and away from the plates by rods 21 which project through a cover plate 5 and operate between stops 23, 24, 25 for moving tapered members 26, 27.

Title: Hydraulic vavles
IPC: F16K35/00
Filed: 1974-08-30
Abstract: 1437747 Valves CATERPILLAR TRACTOR CO 30 Aug 1974 [4 Sept 1973] 38076/74 Heading F2V [Also in Division F1] A pilot spool valve 36 for controlling an hydraulic jack 11, via a main control valve 18, has a spring centring mechanism 39 and fluid pressure operated detent mechanism 52 to hold the spool 37 in the selected position until the jack has completed its travel. The detent mechanism comprises a pair of detents 57 which engage depressions 58, 59 in an extension of the spool. Axial depressions 61 run between the depressions 58, 59 and serve to provide fluid pressure to the inner faces of the detents and also to prevent rotation of the spool. Pilot fluid for operating the main control valve 18 is also fed to the outer ends of the radial bores 53, 54 in which the detents 57 slide. If the spool valve has been displaced fully from the centred rest position the detents engage in the depressions 68 or 69 and lock the spool in this position until the jack 11 reaches the end of its travel. In this position one or other of two cams 31, 32 on an arm 29 attached to the jack rod 14 engage a lever 69 on a valve 33 or 34 to rotate it to a position in which fluid pressure from the pilot pump is fed via a conduit 71 or 73, and a radial bore 72 or 74 to the axial depressions 61. In this condition pressure on the ends of the detents 57 is balanced and the spool will return to the central rest position under the influence of the springs 39. At all times the lateral forces acting on the spool through the detents are balanced. In an alternative embodiment, Fig. 2 (not shown), the facility for automatic withdrawal of the lock is restricted to the upwardly shifted position of the spool only. Any tendency for fluid pressure to build up against the inner ends of the detents, as a result of leakage along the spool, is prevented by an axial groove (101) in the spool leading to a chamber (102) at the end of the spool connected to exhaust.

The casing 3 may be formed of a plastics material and the transparent lid is attached to it by a hinge 7. The treatment liquid is placed on the base plate through the shoot 22. When the heating element which comprises a mica plate-type electric coil heater 20 is energized the heat produced is conducted to the base plate 15 and the posts 12 by a heat conducting plate 19. The plates 15, 19 are held in close contact by flanges 16 at the base of each post. The base plate is held out of contact with the sides of the casing 3 by a supporting member 25. The base plate has a detachable baffle 27 with apertures to pass over the posts to allow the vapourized liquid to pass through. A baffle 30 directs any condensed vapour back on to the base plate. The temperature attained by the heating element 20 is controlled by a thermostat 35. The operating temperature of the heater is varied by shielding the thermostat by an L-shaped aluminium arm 38. A slide assembly 40 allows the arm 38 to be moved to cover a variable amount of the thermostat. The greater the area covered the higher the operating temperature will be. The cabinet may be used without a heating liquid and separate heaters may be provided to heat the liquid and the posts. The posts which are received by internal tubular sleeves 14 of the rollers, may be heated by circulating the heated liquid through them. The cabinet is provided with compartments to hold the mains connecting cable and the hair clips used with the rollers. The lid may be provided with downwardly - pointing pyramidal projections above each of the mounting posts, the rollers having corresponding upwardly directed conical ends.

The path along which the letter travels is divided into sections 11 of such a length that they can contain only one letter at a time. A photocell 12 is arranged at the beginning of each section and is associated with a register 15. As a photocell detects a letter the sorting data relating to the letter is moved into the register 15 associated with the photocell. The path is divided into several branches and deflectors 10 are arranged to move the letter to the correct branch, the deflectors being arranged a suitable distance after a photocell to allow time for the deflector to operate. The sorter is controlled by a data processor which controls the motors, checks on the contents of the pigeon holes and determines whether jamming has occurred, e.g. by determining the time during which a photocell is not covered after the trailing edge of one letter has passed and before the leading edge of the following letter arrives and checks the correct operation of the sorting switches.
