Title: Apparatus for the separation of solid or liquid particles from gases, vapours or smoke
IPC: B01D45/08
Filed: 1935-06-11
Abstract: 461,180. Separating dust from gases. ZANDER, M. June 11, 1935, No. 16849. [Class 8 (ii)] [Also in Group XII] In apparatus for separating dust from gases and vapours, the dust laden gas is passed through a chamber provided with sets of oppositely - disposed inclined baffles 2a-2e. The gas is thus caused to follow a zigzag path so that at the end of each inclined surface, the dust particles are projected on to the opposing wall of the chamber and the top side of the succeeding inclined surface. Curved plates 5 screening the undersurface of the baffles promote the production of eddy currents and assist in the deposition of dust. The distance between the edges of the baffles and the adjacent wall may be diminished in the direction of gas-flow. In a modification, the gas flows through oppositely directed channels Ql, Q2, Fig. 4, separated by a chamber bounded internally by the curved wall 5. Dust is deposited on the substantially vertical surfaces k which are irrigated by liquid supplied by a pipe a. The irrigated surface on which the dust is deposited is profiled by corrugations &c. to facilitate the adhesion of the dust-particles. The irrigating liquid is guided from a reservoir between the edge of the vertically adjustable surface 2 and the spacing wall 10. The spent liquid is collected in the sump 13 the roof of which is defined by the bent-in edge 14<a> of the bottom 14 of the main chamber.

Abstract: 1491153 Tape transport control SHARP KK 24 April 1975 [24 April 1974] 17083/75 Heading G5R Magnetic tape apparatus has a magnetic head 12 arranged to scan the tape 10 during fast forward and fast rewind operations thereof, a detector 16 connected to the output of head 12 and producing a detection signal X when a portion of tape exceeding a predetermined length with no information recorded thereon is sensed, means 18 producing a control signal Y when a presettable number of said detection signals X have been produced by the detector, means 20 for presetting said number to any selected one of a plurality of values, and a tape drive control 24 responsive to the control signal Y to discontinue the fast transport operation. Whenever during fast forward winding or rewinding the replay head 12 senses a silent period on tape 10 longer than a time set by an R-C timing circuit (163), Fig. 2 (not shown), in detector 16, the latter gives the silence detection signal X whereby a decade counter 18 counts down by one, its current count being indicated by a unit 26, such as an LED display. The control signal Y is produced when counter 18 reaches zero. The control 24 receives the control signal Y to change the state of the tape player from the fast forward or rewind state to the stop or normal playback state, display 26 being blanked and the count down input of counter 18 blocked when signal Y is produced. The initial count, representing the number of programmes on tape 10 to be skipped over, is entered into counter 18 by a keyboard 20 via a converter 22, keyboard 20 including a CLEAR key to set the counter 18 to zero, and an auto-clear circuit (185), Fig. 2, being provided to set counter 18 to zero when a power switch of the tape player is closed. The control 24 is a so-called "plunger control" of the type disclosed in Specification 1,448,738 which includes an electromagnetic device effecting the transport mode change when energized. The control 24 responds to the control Y to change modes only when the control signal Y is produced in response to a blank portion of tape after the control signal Y has not been produced in response to a preceding recorded portion of tape.

Abstract: 529,928. Welding panels. BUDD MANUFACTURING CO., E. G. June 12, 1939, No. 17152. Convention date, June 25, 1938. [Classes 83 (ii) and 83 (iv)] In connecting a pair of metal plates to an intervening metal spacer by successive welding of fractional areas thereof each of the successive welded fractional areas is substantially coextensive with one dimension of the assembly. The fractional areas may extend the full width of the assembly and adjoin only along parallel straight lines extending throughout this width so as to avoid warping and buckling during welding. The spacers consist of sinuous strips 12, Fig. 14, provided with triangular spuds 13 which are welded to the cover plates 10, 11 to form a double-walled sheet metal panelling. The length of the welding electrodes 15, 16 corresponds to the width of the cover plates and is wide enough to cover three spuds of the spacer strips. The welding electrodes are pressed into engagement with the work by adjustable springs or by air or hydraulic motors 17, 18, which may be operated in both directions through a control valve by a pump. The electrodes are electrically connected to a set of four transformers. The operation of removing the electrodes from contact with the work is effected mechanically against the fluid pressure in the cylinders. For this purpose the end pieces 86, Fig. 7, carrying the electrode 15 rest on nuts 87 mounted on rack bars 85 on yokes 84 which may be raised by cams 22 on a shaft 60 driven from an electric motor through spur and chain gear. The rack bars engage idler pinions 24 co-operating with central racks 21 so that at the same time the lower electrode is lowered from the work. When the electrode 15 is to be raised to a higher level than that effected by the cams as in initial loading of the machine this may be effected by reversing the fluid pressure motors 17, 18 which carries the end pieces 86 from the supporting nuts 87 independently of the rack bars 85 and at the same time moves the lower electrode downwards, which through the racks 21 carries the side racks 20 and rollers 23 away from the cams. The cover plates 10, 11 are fed from rolls 38, 40 over guides 45, 46 for maintaining them out of contact with the spacer strips 12, by rolls 41, 42 and 43, 44 driven by gearing from a shaft 72 which is driven'by a chain 71 from a shaft 67 intermittently rotated by ratchet mechanism 66, 64, 63, 62 from a cam 61 on the shaft 60. The spacer strips are fed by sinnously grooved rolls 48, 50 connected by spur gears to the driving mechanism of the other rolls. The welded panel is fed from the electrodes by rolls 19 driven from the shaft 67 by chain gear 68 and spur gear through a shaft 70. This shaft 70 also drives chain conveyers 52. The welded panel passes thence between lower and upper feed beds 51, 112. The frame 112 which carries the upper roll 19 is connected at one end by spring pressed bolts to, the main frame and at the other end is adjustable by bolts 106. Specification 504,146 is referred to.
