Title: Separation of solid adulterants from regularly-shaped particulate solids in a carrier gas
IPC: B65G53/60
Filed: 1968-02-15
Abstract: 1,211,292. Pneumatic separation. E. I. DU PONT DE NEMOURS & CO. 15 FFeb., 1968 [17. Feb., 1967], No. 7556/68. Heading B2H. A gas-entrained mixture of regularly-shaped particulate solids and particulate adulterants flowing, through a conveyor line 10, 10a is separated into its components by a separator inserted in the conveyor line and comprising a first expansion chamber 11 in which the gas velocity is reduced below the minimum floating velocity of the adulterants a second expansion chamber 12 in which the gas velocity is reduced below the minimum floating velocities of both adulterants and particulate solids and which is of greater cross-section than the first chamber and of such a length that, when the gas-entrained mixture enters it, the adulterants are separated out from the gas stream and fall into a trap 16 at the bottom of the chamber whereas the particulate solids due to their inertia are carried towards the outlet end of the chamber, and a double-coned member 20 which deflects the gas stream to effect final separation of any entrained adulterants and which defines with a reducer 17 at the outlet end of the chamber a flow-acceleration passage for the particulate solids leaving the chamber 12 with the gas stream. The reducer 17 may be connected to the section 10a of the conveyor line either directly or, as shown, via a duct 18. The gas velocity in the different parts of the apparatus, and hence the degree of separation, is adjusted, by a manually operable gas flow regulating valve 24 incorporated in a by-pass line 23 connected between the conveyor line portion 10 and the outlet end of duct 18.

Title: Improvements in or relating to condenser electrodes for short-wave and ultra-short-wave therapy and method for storing the same
IPC: A61N1/06
Filed: 1935-03-12
Abstract: 431,672. Electromedical appliances. HIRSCHLAND, L., 5, Bismarckplatz, Wiesbaden, and SCHMIDT, G., 14, Am Rosengarten, Mainz, both in Germany. March 12, 1935, Nos. 7613 and 7614. Convention dates, March 13, 1934 and June 6, 1934. [Class 81 (ii)] Condenser electrodes for short-wave and ultra shortwave therapy are characterised by the provision of a dielectric layer c of mouldable non-elastic substance retaining the shape imparted to it; preferably a substance mouldable on warming such as paraffin wax is employed. The dielectric layer is mounted upon a metal plate connected to a conducting rod b or upon a layer d of material having a higher dielectric constant such as hard rubber or artificial resin, the layer d being covered by a metallic layer e, made of foil or produced by spraying. In use the electrodes are stored in a heated enclosure, or on heated plates of corresponding shape, and are moulded to the part to be treated before application thereto ; the moulding may include the production of a cavity c<1> when boils or the like are to be treated. In a further modification the mouldable layer is mounted on a glass container enclosing a metal plate, movable towards and away from the body, to adjust the capacity of the electrode, by a stem passing through the container cover.

Title: Improvements in electric regulators of the carbon pile type
IPC: H02P9/22
Filed: 1942-06-08
Abstract: 558,622. Automatic regulators. STONE & CO., Ltd., J., and NIXON, L. R. June 8, 1942, No. 7798. [Class 38 (iv)] In a carbon pile regulator a presser device for the pile is flexibly connected to the operating magnet armature and guided for movement axially of the pile to avoid application of any unbalanced or tilting force. A clapper plate d carries the armature c having two blades entering air gaps in the magnetic circuit of the regulator magnet, which blades are contoured to effect a balance between characteristics of armature traction and compression spring. The plate d turns about the crossing of two blade springs c, f by which it is mounted on the regulator frame and is connected by lugs d<SP>2</SP> to compression springs (not shown) and by drop arms d<SP>3</SP> to flexible metal strips or tapes m, m' secured to a presser ring j. This ring is secured to a rigid bar k which is supported by bow springs l, l<SP>1</SP> on the frame to which it is secured by lugs k<SP>1</SP>, k<SP>2</SP> so that it is constrained to move parallel to the axis of the pile h. The drop arms produce a reduction in the mechanical advantage of the spring pressure as the clapper plate tilts under magnetic traction. As applied to a regulator with rotary armature a rigid bar 4, Fig. 3, is connected to two diaphragms 5, 6 whereby it is guided parallel to the axis of the piles 14 to which it is connected through a pin joint 9 and balancing plate 11 to presser means 13, Fig. 5. The rotor n is connected to a sector p and flexible strip q whereby the tension of a spring r is applied and to an arm s which is connected to the pressed means by a lever y, y<SP>1</SP> and flexible strips w, 3. The strip w is indirectly connected to the arm y through an arm w, spring 2 and a screw 1 whereby the pressure applied to the piles may be adjusted. When the rotor n turns in a direction to relieve the pressure an abutment u carried by the arm w contacts the screw 1. Specification 558,621 is referred to.

[Also in Group IV (a)] The invention comprises new epoxide compounds of the formula in which R 1  to R 9  and R<SP>1</SP> 1  to R 9 <SP>1</SP> represent monovalent substituents such as halogen atoms or alkoxy groups or aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon residues, preferably C 1  to C 4  alkyl radicals, or represent hydrogen atoms and R 1  and R 5  together, or R 1 <SP>1</SP> and R 5 <SP>1</SP> together, may also represent an alkylene group, such as a methylene group; Z represents an aliphatic, cycloaliphatic, araliphatic or aromatic residue which may contain hydroxyl, ether, sulphide, carboxyl, carboxylic ester, keto or acetal groups or more than two 3,4-epoxycyclohexylmethyl carbonate groups; and n=1 or 2. The novel compounds may be made by treating the corresponding unsaturated carbonate ester with an epoxidising agent, preferably a peracid, such as peracetic, perbenzoic, peradipic or monoperphthalic acid. Alternatively, the epoxidation may be effected by treatment with hypochlorous acid and dehydrochlorination with a strong alkali. The bis(#<SP>3</SP>-tetrahydrobenzyl) carbonates may be made by reacting at least two moles of a #<SP>3</SP>-tetrahydrobenzyl alcohol or of a mixture of two or more such alcohols, with 1 mol of phosgene or 1 mol of a carbonic ester. The organo - bis (#<SP>3</SP> - tetrahydrobenzyl carbonates) wherein the organo radical is Z as defined above, are made by reacting 1 mol of a #<SP>3</SP>-tetrahydrobenzyl alcohol with 1 mol of phosgene to form the chloroformic acid ester and reacting this with a polyhydroxy compound. Alternatively, the polyhydroxy compound may be reacted with phosgene to form a polychloroformic ester which is then condensed with the #<SP>3</SP>-tetrahydrobenzyl alcohol. Many dihydric and polyhydric alcohols, phenols and sugars are specified. The novel polyepoxy compounds can be hardened in conventional manner (see Group IV (a) ).
