Title: Improvements in or relating to the distillation of tar and like hydrocarbon oils
IPC: C10C1/04
Filed: 1934-11-27
Abstract: <PICT:0452710/IV/1> Tar acids are selectively distilled from tars, tarry oils and like without removal of hydrocarbon fractions of similar boiling point by heating the tar to 125 DEG  C. or higher and then treating it with inert gases or vapours mixed with hydrocarbon vapours, the vapours evolved being preferably passed through a phenol absorber to recover the tar acids and preferably recycled to the distillation stage.  Tar from a tank 1 is preheated in a coil 4 and sprayed into a packed tower 7 to the bottom of which inert gases and vapours are supplied by a pump 10.  The vapours evolved pass to a scrubber 15 in which they are treated with caustic soda solution supplied through a line 17 and circulated by a pump 21 through the scrubber and a heater 23.  The gases and vapours leave through a line 16 and are recirculated in part through a line 29 by the pump 10. The phenolate solution is drawn off through a line 18 and the tar through a line 8.  British Specification 448,109 and U.S.A. Specification 1,956,597 are referred to.ALSO:Tar acids are selectively distilled from tars, tarry oils, and like without removal of hydrocarbon fractions of similar boiling point by heating the tar to 125 DEG  C. or higher and then treating it with inert gases or vapours, mixed with hydrocarbon vapours, the vapours evolved being preferably passed through a phenol absorber to recover the tar acids and re-cycled to the distillation stage.

Title: A method of pressing compact shaped bodies from plastic substances, particularly ceramic pastes, such as roofing tiles, pantiles or the like
IPC: B28B13/06
Filed: 1954-11-26
Abstract: 801,313. Making tiles &c. from ceramic pastes, &c. BUHLER, GEB. Nov. 26, 1954 [Dec. 2, 1953], No. 34283/54. Class 87(2). Tiles are pressed from ceramic paste between two electrically conductive surfaces which are insulated from each other and to which direct current electrical potentials are applied in such manner that the surfaces are in turn, once during each pressing operation, subjected to a negative potential with respect to the pressed article. The potential loosens the article from the surface and the Specification briefly discusses this phenomenon. A die c is carried by, but electrically insulated from, a reciprocable member d and a series of co-operating dies b1-b5 are brought in succession opposite the die c by the intermittent rotation of a drum a on which they are mounted. A cam n operates a reversing switch whereby D.C. negative potential is applied to the die c and to a co-operating die b alternately during each pressing operation. The drum a is indexed to its next position, where a knife carried by a frame r trims the pressing. Negative electrical potential is utilized to free the knife from the trimmed material, for which purpose the knife frame is insulated and permanently connected to the negative pole of a D.C. source k. The source k is separate from the source m, since it requires to be of such a nature that the short-circuit current resulting from contact between the knife blade and drum is limited : thus it may be a transformer and rectifier (not a battery as diagrammatcally shown), the transformer having a large leakage reactance. The source m may also be a transformer and rectifier. In a modification, Fig. 2, the drum a is connected to a central tapping  S  of the D.C. source, the negative pole of which is permanently connected to the reciprocable, insulated die c. Within the knife frame h<SP>i</SP> is a plate p complementary in shape to the mould b and forming an electrode connected to the positive pole of the D.C. source. At the trimming position the knife makes contact with the mould b and acquires the same potential as the drum, i.e. negative with respect to the plate p and therefore the pressing, whereby the trimming knife is loosened from the material.

Abstract: 1,129,884. Supply -systems for arc furnaces. G.W.B. FURNACES Ltd. 10 Nov., 1965 [21 Aug., 1964], No. 34298/64. Heading H2H. The heavy current connections between the electrodes 2 of an arc or reduction furnace and a three-phase transformer 6 are each in the form of two physically -adjacent conductors comprising.a "go" and a "return." Thus the delta connections of the secondary windings 7 of the supply transformer are made at the furnace electrodes and the reactance of the heavy current connections is minimized. The connections comprise water-cooled insulated cables, the cooling water flowing along each cable being controlled by a valve 19 situated between a tank 11 and a sump 12, a pump 13 being used to restore the water -to the tank from the sump. The valve 19 is controlled by a control unit 16 to which are fed signals from a current transformer 17 responsive to the current supply to an electrode 2, thermo-couples 14 monitoring the temperature of the furnace roof, thermo-couples 15 responsive to the temperature of the furnace wall and a thermo-couple 18 responsive to the temperature of the water in the cable, so as to control the temperature and hence the resistance of the cable whereby enhanced balancing of the electrode currents may be obtained.

Abstract: 398,817. Helical springs. CHATILLON & SONS, J., 85, Cliff Street, New York, U.S.A.-(Assignees of Wasson, R. B. ; Riverview Apartments, Riverside Drive, Cranford, New Jersey, U.S.A.) Dec. 14, 1931, No. 34620. Convention date, Dec. 20, 1930. [Class 108 (iii).] Cylindrical helical springs particularly for use in force resisting systems such as weighing machines are made of wire of uniform elliptical or rectangular cross-section arranged so that, respectively, the minor axis b or breadth b is transverse to the axis of the coil the crosssections being such that for elliptical crosssections the ratio of the minor axis b to the major axis a is, substantially, a = 3À87b and for rectangular cross - sections the ratio of the breadth b to the depth d is, substantially, d = 1À66b, the object being to obtain uniform rate of deflection with respect to load. In a modification the dimensions of a spring of rectangular or elliptical cross-section are so chosen that (3-2<GJ>/EI)= a minus quantity not exceeding - 0À2 (where G = modulus of elasticity in shear or torsion ; J = coefficient used in torsional deflection formula; E = modulus of elasticity in tension and I = moment of inertia of section about a substantially vertical axis) and such a spring is combined with a cylindrical helical spring of circular cross-section and a calibrating device. In one form, a weighing machine includes springs 4 of rectangular cross-section dimensioned as above, dashpots 7, and load transmitting bar 6 carrying racks 12 operating pointers which move over front and rear dials. The rectangular or elliptical cross-sectioned springs and the circular cross-sectioned may be arranged in series or parallel and in one form the calibrating device used in conjunction therewith has a thread of non-uniform thickness engaging between the coils of the spring. The Specification contains a mathematical investigation for determining the deviation of springs from uniform rate of deflection with respect to load. The Specification as open to inspection under Sect. 91 describes other constructions for achieving the object of the invention these include, combining helical springs of circular cross-section with cantilever-spring-hooks and calibrators ; employing an arcuate rack or quadrants and weighted levers between the load transmitting bar and the pointer ; and bending the bottom end of a spring of circular crosssection up into the coils. This subject-matter does not appear in the Specification as accepted.

A branch current of compressed unsaturated hot gas is supplied via conduit 21 to a regenerative zone 13 of apparatus 9 in which said branch current gas takes up moisture absorbed from the main current gas, thus restoring the drying properties of the apparatus. The drying member of apparatus 9 is a rotor 10 and portions thereof alternately pass through the drying and regenerative zones 10, 13. The rotor is formed by folded asbestos sheeting impregnated with lithium chloride and reinforced by metal wire. After performing its regenerative function the branch gas is passed through a return conduit 23 with cooler 24 to the suction side of ejector 8 and from there joins the main current to the drying zone 14. The dried gas is discharged through conduit 20.
