Title: Improvements in electric discharge tubes
IPC: H01J19/28
Filed: 1935-10-31
Abstract: 446,956. Discharge apparatus. SOC. FRANCAISE RADIO - ELECTRIQUE, 79, Boulevard Haussman, Paris. Oct. 31, 1935, No. 30126. Convention date, Nov. 16, 1934. [Class 39 (i)] In a discharge device having an externally cooled hollow anode 3, one end of which is closed, and a cathode 1 adapted to be heated and enclosed within the said hollow anode, a plurality of grooves or strictions 5 is provided on the interior wall of the hollow anode and arranged so as to reflect the heat variation from the cathode towards the closed end of the hollow anode. The closed end of the anode has similar grooves or striations to diffuse the reflected heat rays. The other end of anode is closed by a glass portion 4, and baffle plates 11, 12 arranged on the cathode leads screen the glass from direct heat rays such as 9, 10. Further screens 13, 14 are attached to the anode. The device is particularly suitable for use on short waves as the spacing of the electrodes can be made large and their mutual capacities small, while at the same time dangerous heating of the glass and consequent dielectric losses are avoided.

Oct. 31, 1933, No. 30240. Convention date, Nov. 2, 1932. [Class 135.] The flow of liquid refrigerant from the condenser to the evaporator is controlled by a tube, the internal diameter of which is such that the refrigerant passes through the tube with turbulent flow at approximately its critical velocity at the lowest working pressure difference between the condenser and the evaporator. Further, the length of the tube is such that the desired rate of flow is secured. The diameter and the length of the tube can be calculated from the known characteristics of the refrigerant and the required rate of flow, and in the case of a machine using methyl formates as the refrigerant may be 0À0137 and 3À56 inches respectively. The tube 21 may be secured in an outer tube 15 enlarged at its upper end to accommodate a filter 24.

Title: Apparatus for channelling sole blanks
IPC: A43D43/02
Filed: 1920-10-27
Abstract: 153,028. Ehresmann, A., and Streibel, L. Oct. 27, 1919, [Convention date]. Vertical-cutter type.-In a machine for channelling sole blanks, the knife is automatically adjusted so that the depth of the incision, instead of being constant, varies in definite proportion with any variation in the thickness of the sole. The sole blank l is pressed up against the feedwheel d by the action of the spring c on the bracket b. The knife i is carried by a lever e which is pivoted at f to the bracket b, while its other end works by a slot over a pin g on the fixed frame a of the machine. If the sole is thin at any place, the bracket b rises an equivalent distance, but the knife only rises an amount represented by the ratio of the distance h, f, to the distance g, f. The sole is pressed against the fence k which is capable of adjustment. The pin g may be formed as an eccentric to adjust the knife relatively to the bracket b.

Abstract: 647,869. Ratchet gearing. A. P. V. CO., Ltd. Nov. 26, 1948, No. 30715. [Class 80(iii)] [Also in Group XXIII] A ratchet device for spanners, jacks, tube expanders &c. comprises two relatively rotatable elements: a pawl-carrying driven element 10 and a driving element 26 having an internal annular. series of teeth 31. The two elements are held together, axially by a ring 27 screwed on a flange 14 of the element 10. An annular block 17 is retained in a recess 16 in the element 10 by a bolt 24, and carries a pivoted pawl 19. The pawl is normally held by a spring 21 against the end 23a of a slot 23 in the part 15 of the element 10. In a modification a reversible drive is obtained by forming the radial hole 25, in which lies the bolt 24, as an annular slot corresponding to the slot 23. The block 17 may then be turned in the recess 16 to bring the pawl against either end of the slot 23, and may be retained in either position by the engagement of a spring-pressed ball, carried by the block 17, with a depression in the annular face of the recess 16. Alternatively the pin 24 may be axially spring-loaded.

Title: Improvements relating to the synthesis of condensable hydrocarbons
Inventor: SECORD CAMPBELL HERBERT
IPC: C01B3/22
Filed: 1953-11-06
Abstract: <PICT:0802145/IV (b)/1> A process for obtaining liquid hydrocarbons comprises subjecting coal or other carbonaceous solid material or gaseous or liquid fuel in a gas-producer to a hot blast medium comprising preheated air and the gases produced are subjected to catalytic synthesis, the products of which are separated by condensation into liquid or solid hydrocarbons and residual or tail gases which are burnt in air and the resultant heat is utilized in a heat exchanger to preheat air which is used to form the blast medium. Lime and iron ore may be added to the coal in the gas producer so as to absorb a high proportion of the sulphur that may be present and at the same time causing the smelting of the iron ore.  The condensed hydrocarbons may be cracked to form petrol and oil fractions.  In a preferred system a stream of air and steam enters the main inlet flow path at A, is compressed to 10 to 50 atmospheres in a compressor 1 and enters a regenerator 2.  The greater part of the gas stream enters a liquid-slagging fixed-bed gas producer 3 as blast air and coal and limestone are added at B.  The gaseous products after passing through a sulphur and dust cleaning means 5 are supplied to a catalytic synthesis reactor 6 in which hydrocarbons of the paraffin series are synthesized.  The products are treated in a condenser 7 and the condensable hydrocarbons removed through D.  The tail gases proceed through a booster 8 to bring the pressure up to 10-50 atmospheres and is then burnt together with air to provide heat in heat exchange for the regenerator 2.  The exhaust combustion gases at a temperature of 600-700 DEG  C. are expanded through a turbine 9 which is arranged to drive an alternator 10 to produce electricity. Compressor 1 is driven by a steam turbine 11 which in turn is supplied with steam produced in the reactor 6.  Alternatively compressor 1 is driven by gas turbine 9 using as a working fluid the combustion products of residual gas and air.

Title: Improvements in or relating to molasses treatment
Filed: 1956-10-11
Abstract: In extracting glutamic acid from sugar-beet molasses, the molasses is diluted with water or baryta water so that it contains between 40 and 70%, by weight of dry substance, excluding barium compounds, and is then treated with at least 60%, preferably between 65 and 85%, based on the weight of sugar in the molasses, of barium oxide or its equivalent of barium hydroxide, preferably in the form of an aqueous slurry, at a temperature between 50 DEG  and 85 DEG  C., for a period of one-half to five hours, varying inversely as the temperature, to precipitate the sugar as barium saccharate and hydrolyse glutamic-acid-producing compounds, such as glutamine and pyrrolidone-carboxylic acid, in the mother liquor.  The latter is then separated from the barium saccharate, e.g. by filtration. Barium ions remaining in the mother liquor are precipitated in the form of barium carbonate by treating it with sodium or potassium carbonate or by passing a gas containing carbon dioxide through the mother liquor until its pH value lies between 8 and 10, preferably after having added to the mother liquor between 0.4 and 3% of its weight of sodium or potassium hydroxide or carbonate. The precipitate is separated, e.g. by filtration, from the mother liquor which is then concentrated to contain 50 to 60% of solid matter, acidified, e.g. with hydrochloric acid, to bring its pH value between 5 and 6, and concentrated to effect the separation, by fractional crystallization, of glutamic acid from inorganic salts.ALSO:In extracting sugar from sugar-beet molasses, the molasses is diluted with water or baryta water so that it contains between 40 and 70%, by weight, of dry substance, excluding barium compounds, and is then treated with at least 60%, preferably between 65 and 85%, based on the weight of sugar in the molasses, of barium oxide or its equivalent of barium hydroxide, preferably in the form of an aqueous slurry, at a temperature between 50 DEG  and 85 DEG  C., for a period of one half to five hours varying inversely as the temperature, to precipitate the sugar as barium saccharate.  The precipitate is separated from the mother liquor, e.g. by filtration.  The separated barium saccharate, e.g. after having been washed with baryta water, is slurried in water and a gas containing carbon dioxide is passed through the resulting slurry to precipitate substantially all the barium as barium carbonate; liberated sugar being retained in solution.  The solution is separated from the barium carbonate by filtration and sugar is crystallized from the filtrate.  The barium carbonate may be calcined to produce barium oxide.
