Title: Method for separating dispersed matter from a fluid mediu
IPC: B03C3/40
Filed: 1975-08-19
Abstract: 1527103 Electrostatic separation G C YEH 19 Aug 1975 [19 Aug 1974] 34396/75 Heading B2J [Also in Division H1] In the separation of dispersed matter from a fluid the mixture is subjected to the field of a dense and uniform corona discharge produced by an electrically conductive filter-like separating electrode 20, Fig. 1, which is pervious to the passage of the fluid and at least a major portion of the dispersed matter, whereby the dispersed matter having an electrostatic charge of the same polarity as the separating electrode is selectively repelled therefrom while the fluid containing a reduced concentration of dispersed matter is passed through the separating electrode. The dispersed matter in the fluid may comprise finely-divided particles including microorganisms such as bacteria and viruses or any ionizable chemical species such as molecules, atoms and radicals, and may be ionized or electrostatically charged either by the field of the corona discharge from separating electrode 20 or before it is introduced into this field. As shown, the separating electrode 20, comprising a filter of fine wire mesh, coil, felt or cloth or a porous metal plate having pointed exterior surfaces, is disposed in an enclosure 10 to divide the chamber 15 therein into two zones A and B. The enclosure 10 may be formed entirely of insulating material or, as shown, may have one wall 30 forming an earthed collecting electrode, with the separating electrode 20 being connected to an electrostatic charge generator 25 having an output in the range +60Kv. Particulate matter or molecular species in chamber 15A having the same electrostatic charge or ionization polarity as the separator electrode 20 are repelled therefrom and are withdrawn from fluid outlet 14, the remainder being withdrawn from fluid outlet 13 in chamber 15B. In an alternative arrangement the separating electrode may be moved through stationary fluid. A number of separating electrodes may be arranged in series in an enclosure, Fig. 3 (not shown), with the disposed matter being separated from the fluid in a stage-wise fractionation, and it is stated that fractionation of a mixture of various molecular species can be accomplished and a mass spectra of disposed matter determined. In an alternative embodiment, Fig. 2, the separating electrode consists of a combination of a conductive coil 50 and a fine mesh conductive screen 52 both mounted on a hollow glass spool 51 and the enclosure 40 also acts as a collecting electrode 60. Fluid containing dispersed matter enters chamber 46 through tangentially disposed inlet 41, the dispersed matter being withdrawn through outlet 44 and the remaining fluid through outlet 43 communicating with the hollow interior of the spool 51. Numerous examples are given and factors influencing the efficiency of the separation are discussed.

Abstract: 1,210,350. Spark chamber detectors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 9 July, 1969 [1 Aug., 1968], No. 34553/69. Addition to 1,089,018. Heading H1D. The anode of the spark chamber detector (Fig. 1, not shown) of the parent Specification consisting of a continuous layer of tin oxide on a glass plate is divided into a plurality of elements 20 electrically separated from one another, having substantially equal areas, and connected individually to the positive pole of a high-tension source. Each element 20 is connected to a conductive ring 16 by way of a resistor in the form of tin oxide deposited on thin glass cemented to the opposite face of the glass plate from that supporting the elements 20 and connected to an element 20 by a conductive adhesive. The individual elements 20 have a lower inter-electrode capacitance to the grid of the chamber than the prior large anode, thus reducing the time required for recharging after a spark occurs. Furthermore, during the dead time of a portion of the detector corresponding to one anode element, portions corresponding to the remaining anode elements can still operate.

Abstract: 172,222. Wellman Smith Owen Engineering Corporation, Ltd., and Thompson, F. W. Dec. 7, 1920. Castings, extracting. - Means for forcing an ingot out of its mould, and thereafter raising the mould clear of the ingot, comprises an overhead trolly (not shown) carrying a hoisting gear and supporting a cage 2 within which a platform 3 can move. To the underside of the platform a plunger 6 is secured by a spring to allow some relative movement. Below the platform is a crosshead 7 carrying hooks 8 to engage lugs 12 on the mould and two sets of sheaves 10. The hoisting rope is passed from the hoisting-drum on the trolly round a sheave 10 on the cross-head and then round a number of similar sheaves on the platform and cross-head. The platform is prevented from rising when the dogs 13 are in engagement with the racks 14 carried by the cage 2 as shown in Fig. 1. Bars 11 secured to the cross-head pass up through the platform and have enlargements 11<a> which in the position shown bear on rollers 15 to hold the dogs 13 in engagement with the racks. When hoisting begins the mould rises while the ingot is held by the plunger so that the mould is freed from the ingot. When the cross-head has risen sufficiently to raise the parts 11<a> clear of the rollers 15, a weight 22 frees the dogs from the racks and rotates cams 18 to grip the bars 11 between them and the rollers 21. The cross-head and platform then are raised together until the mould is clear of the ingot. As the cross-head begins to rise, a pedal 34 is depressed to put a brake on the rod 31 and close the hooks 8 into engagement with the lugs on the mould. When the mould has been lowered on to the ground a weight 29 opens the hooks clear of the lugs. Other means of connecting the platform and cross-head are described and shown.

Title: Improvements relating to a method for regulating the supply of gas from a reservoir to an internal combustion engine and to apparatus therefor
Filed: 1937-12-20
Abstract: 490,117. Regulating. ZAN, T. Dec. 20, 1937, No. 35216. Convention date, June 2. [Class 7 (vi)] Gas supplied at 15 to a reservoir 1 passes through a connection 17 to a chamber 18 closed by a valve 19 in the induction pipe, the inlet 15 to the reservoir being controlled by a spring-closed valve 12 connected by a spindle 6 to a diaphragm 4 at the top of the reservoir. The valve 19 is also closed by a spring 26, and the two springs are so adjusted that when the gas pressure in the reservoir is sufficient to lift the diaphragm 4 to close the valve 12, the gas pressure is just sufficient also to open the valve 19. The suction of air past the valve 19 then causes it to open to admit gas to mix therewith. This air suction acts upon the head 20 of the valve 19. At starting, the spindle 6 may be depressed by hand to cause an outflow of gas past the valve 19. The reservoir 1 and chamber 18 may be made in the form of a single chamber with a dividing wall.
