In Coulter type apparatus, fluid from a single source is drawn through a number of apertures of the same or different sizes, a single common electrode being arranged in the source of fluid and individual electrodes being arranged in the steams of fluid flowing through the apertures. In one embodiment, Fig.5 (not shown), a number of conventional aperture tubes (52), (53), (54) are immersed in the fluid (63), together with a common electrode (65). The tubes are connected to fittings (58), (59), (60) of a barrel (61) of a stop cock (62). In a second embodiment of a two aperture apparatus, Figs.1-4, Fig.1 (shown), a tube 10 is divided by a central partition 11, its upper end being bi-furcated to form two branches having the necessary outlets and each provided with an electrode, e.g. 24. Apertures 34, 35 are formed in wafers 38, 39 of glass or sapphire which are set in a flattened face 40 or faces (51, 52, Fig.4 not shown), at the lower end of the tube which is immersed in the fluid 31 under investigation together with one electrode 32. In a further embodiment, (Figs .10-12) Fig. 11, (shown), six wafers e.g. 129, having apertures e.g. 128, are mounted at varying heights in the side wall of a vessel 166 containing the fluid 146 and a common electrode 139. Inlet and outlet conduits, e.g. 133, 134, are mounted over the apertures each including an electrode e.g. 135. The bottom of the vessel is provided with an outlet and stop cock for drainage purposes. In another embodiment for investigating a flowing fluid, Figs.6-9 Fig.6 (shown), wafers 94, 95, 96 having apertures 91, 92, 93 are mounted on a plate 90 engaged in a seat 88 in the side of a conduit 86 through which the fluid is flowing.

Abstract: 1356528 Chucks CARL ZEISS JENA VEB 15 Nov 1972 52688/72 Heading B3B [Also in Division H1] A magnetic chuck for clamping and centring a workpiece in a machine tool comprises a body 1, a magnetic coil 2, magnetizable pole collars 3, 4 and a further magnetizable collar 5 for closing the magnetic circuit. The body carries a clamping cylinder 7 at one end having longitudinal equiangularly spaced longitudinal slits 6 dividing it into independently expansible resilient strips 8 carrying clamping teeth 11, 12 at alternate ends to engage the workpiece. Cylinder 7 and the magnetic system fit into cap 9 and are secured by disc 10 while the cap is screwed onto body 1. On energization of coil 2, magnetic flux flows over collars 3, 4, 5, air gaps 15, 16 and strips 8; the latter being outwardly expanded by the flux in air gaps 15, 16 to permit insertion of a workpiece 13. On deenergization the strips are restored to grip and centre the workpiece over stops 11, 12. In a mandrel operating similarly, the slotted clamping cylinder is attached to the base, and within it is positioned a magnetic coil and armature which is energizable to inwardly expand the strips of the cylinder to which stops are fitted outwardly. An apertured workpiece can be placed over the mandrel to be gripped inwardly by the strips on de-energization of the coil (Fig. 3, not shown).

Abstract: 532,440. Thermal-switches. SANGAMO WESTON, Ltd. Aug. 31, 1939, No. 25000. Convention date, March 30. [Class 38 (v)] (Also in Group XXXVI and XIII] A thermostat comprises a thermallyresponsive element adapted to be heated, and a heating element which in response to changes in ambient temperature is variably posmonea relatively thereto. An active bi-metallic element 1 and an opposing bi-metallic element 2 exposed only to ambient temperature are clamped in one plane between separable portions of a post 3 rotatable by an adjusting pinion 4. A third bimetallic element 5 is clamped by the post 3 parallel to the active element 1 and spaced therefrom. The free ends of the elements 1, 2 are connected by insulating strips 6, to which is secured an operating arm 7. A control spring strip 8 is also clamped by the post 3 in a plane parallel with the element 5, its free end being connected with the free end of the element 5 by an insulating strip 9. Both elements 1, 5 may constitute resistance heaters and current may be passed through them either in series or in parallel. Both elements move in the same direction when heated, the heat received by the element 1 by radiation from the element 5 compensating for the greater radiation loss at high temperatures. The compensation may be adjusted by shunting either of the elements 1, 5. In Fig. 4. the opposed bi-metallic elements 10, 11are of spiral form and mounted on a spindle 12. The active element 10 is heated by an external resistance 15. A compensating heater 18 is carried by an arm 17 moved by a bi-metallic strip 16 so arranged that increase of ambient temperature causes the heater 18 to move nearer to the element 10 so as to compensate for increase in radiation. Alternatively the heater may be arranged to heat the compensating element 11 and to be moved further away from it on increase of ambient temperature. The element 16 may be adjusted by a screw 21, and restraining and assisting springs 22, 23 may operate on the arm 17 and be adjusted by screws 24.

Abstract: 1,171,141. Ion pumps. ULTEK CORP. 29 Nov., 1966 [3 Dec., 1965], No. 53307/66. Heading H1D. In an electronic vacuum pump including a pump chamber 11, at least one anode 21 and two cathodes, one associated with each side of the anode, disposed in said chamber, and means 44 for applying a voltage between said cathodes and said anode, said cathodes are formed from materials having different sputtering rates, and at least one of said cathodes is formed from a material selected from Ti, V, Zr, Mo, W, Th, Hf, Nd, Ta and their alloys. The latter materials are reactive and are thus effective in pumping active gases such as nitrogen and oxygen. The net transfer of material from one cathode to the other improves the pumping of inert gases by preventing the re-emission of inert gas atoms from the cathode which gains material. One cathode may be made of a metal having a high sputter yield, e.g. Zn, Cd, Au, Ag, Cu and their alloys. Preferred metals are Ti for one cathode and Ta or Cu for the other. In the pump shown each anode is multicellular and forms with its associated cathodes an assembly which is mounted in a pocket 19 forming part of the chamber 11. Magnetic fields are provided by ferrite bar magnets 22 with polepieces 23.
