Title: Improvements in or relating to process and apparatus for the elimination of foreign particles from gases
IPC: B03C3/16
Filed: 1957-08-28
Abstract: 838,730. Electrostatic precipitation. VICARD, P. G. Aug. 28, 1957 [Nov. 2, 1956 ; Feb. 1, 1957], No. 27090/57. Class 39(1). [Also in Group XII] In a method of removing foreign particles suspended in a gas the gas to be treated is sprayed with a liquid, e.g. water, at 3 to saturate the gas with the vapour of the liquid and at 4 with a mist of the liquid to supersaturate the gas before entering the throat 5 of a Venturi-tube where condensation of the liquid on the foreign particles occurs, the gas then being submitted to an ionizing electric field before the liquid condensed on the foreign particles has evaporated and ionized foreign particles being separated from the gas. In the apparatus shown in Fig. 1, the ionization of the wetted foreign particles is effected in an insulated chamber 7 which is joined to the outlet of the Venturi-tube and in which there is created an intense electric field between one or more wires or high voltage electrodes 8 and earthed surfaces 9. The ionized wetted foreign particles collect on the earthed surfaces 9 and run off through an outlet 10. The ionizing electrode may also be formed of a plurality of wires disposed normally to the gas stream. In the apparatus of Fig. 2, the electrode or electrode system 8 is extended into and through the throat of the Venturi-tube, earthed surfaces 11 and 12 being arranged as shown. The surface 11 may be perforated and precipitating surfaces 13 are provided in the insulated chamber 7. Removal of the ionized wetted foreign particles may be effected by an electrostatic precipitator, a centrifugal separator, a filter or a scrubber. In a modification a Venturitube having a succession of convergent-divergent sections is employed.

Title: Improvements in or relating to riveting machines
IPC: B21J15/10
Filed: 1938-09-19
Abstract: 519,535. Punching; riveting. HEINKEL, E. Sept. 19, 1938, No. 27299. [Class 83 (iv)] A machine for riveting together thin imperforate parts 3, 4 of metal or other material by means of countersunk rivets comprises a reciprocable stamp 6, means 12 for supporting a rivet in suitable position for being struck by said stamp through the work 3, 4 while supported by a countersunk bolster 16 and a die 19, Fig. 2, for forming a closure head on the rivet while this is engaged by the stamp. The bolster 16 and die 19 are held down by springs 18 in a slide 14 which is laterally moved by a lever 15a and an oscillating eccentric 51, Fig. 3, in timed relation with the stamp 6, to bring these tools 16, 19 alternately into position between the rivet and a slide 22 which is reciprocated vertically by a link 23 and the eccentric to raise the tools 16, 19 alternately into the guide 5. The work is clamped to the guide 5 by a sleeve 12 and a spring-pressed sleeve 7. To prevent the wads punched from the work, which normally fall out through a bore 17, from sticking to the rivet, the bolster or a sleeve 40, Fig. 5, carried thereby may have a slotted extremity adapted to grip the wads 41 when engaged in the guide 5 but to release them when withdrawn. In a modification the rivet is placed by hand or feeding mechanism between spring-pressed jaws 30, Fig. 4. As the stamp 6 comes down a collar 38 strikes levers 37 and withdraws the jaws 30 and the rivet engages the work 3, 4 resting on a spring-supported guide 5 and forces these parts down until the work is arrested by the stationary bolster 16 and the rivet passes through it. The stamp 6 then rises enough to allow.the guide À5 to return to the position shown and a spindle 21 is raised to engage the bolster and form with it a die which heads the rivet when the stamp moves down again. If desired the rivets may be fed, by mechanism not shown, through an opening 43, Fig. 6, to a guide tube 42 having three spring-pressed centring levers 47 and also, if desired, three spring-pressed balls 44.

Title: Method and device for producing rubber profiles
Inventor: EGGER GEORG MICHAEL
IPC: H02P5/50
Filed: 1970-06-06
Abstract: 1,273,130. Controlling extrudate take-up speed. G. M. EGGER. 6 June, 1970, No. 27488/70. Heading B5A. [Also in Division G3] A solid or sponge rubber profile is extruded from a nozzle and conducted through a bath of heating liquid for vulcanization thereof which is provided with vacuum means 11 for removing gases, the liquid having a specific gravity in the order of that of rubber. At the exit of the treating vessel, the vulcanized profile passes over rollers to a unit for washing, drying, applying powder to the profile, and for winding it on to take-up reels. Automatic control is provided for  continuous co-ordination of the extrusion speed  and the exit speed whereby the cross-section of the profile is kept constant, and profiles of  different size are produced by adjusting the speed-ratio. In one arrangement, the two speeds are detected by respective D.C. tachometer generators whose signals are compared in an amplifier which supplies the field winding of a motor driving an exit roller. The signal derived from the tachometer generator which is driven by the exit roller is generally reduced by a potentiometer before application to the ampliefier so that the exit speed is greater than the extrusion speed, Fig. 3 (not shown). In another embodiment, the tachometer generators 25, 26 are of the three-phase type connected to a phase indicator 27 which turns in a direction determined by the faster generator. Finger 28 engages contact 29 or 29<SP>1</SP> associated with field windings 22, 22<SP>1</SP> of motor 20. The latter drives the exit roller 17, and is coupled to the tachometer generator 26 through variable gear 33.

Title: An improved process or method of and apparatus for levelling flattening or straightening sheet metal or metal sheets
IPC: B21D1/00
Filed: 1924-11-20
Abstract: 239,402. Sjolander, C. G. L. Nov. 20, 1924. Straightening; dies.-Sheet metal, particularly of thickness up to 2 mm. and breadth up to 1.5 m., is levelled, flattened, or straightened by feeding intermittently and bending at each step alternatively in opposite directions, each successive bend being of less proportions than the preceding bend, and in each step causing each successive bend to overlap a portion of the previous bend so that the bends diminish progressively and are ultimately eliminated. The small buckles and surface strains are thus eliminated in addition to the large buckles. The sheet is fed step by step by rolls 16 between a pair of relatively movable dies 1, 2, which are respectively provided with swells 3-8 and 9-15, the swells on one die engaging with the grooves on the other die. The swells 3-6 and 10-13 progressively decrease in height and width and distance between successive swells, whereas the swells 7, 8 have an equal height and the swells 13, 14, 15 have an equal height and are separated from each other by a progressively increasing distance to neutralize the effects of smaller differences of thickness in the sheet. The sheet is fed forward by regular steps which do not coincide with the distances between the bending parts of the dies.
