Abstract: 644,366. Brackets. G. B.-KALEE, Ltd., and BELL, C. H. Jan. 31, 1947, No. 3044. [Class 52 (v)] In theatre chairs of the kind having tip-up seats mounted on side standards fixed to the floor in rows the seat 12 is provided with stub shafts 60 the spherical ends of which bear in bearings 76 in the standards 20 the stub shafts 60 being axially movable in relation to the seat preferably automatically by the aid of springs 66 housed in a tube 64 and bearing upon the ends of the stub shafts 60. This permits the distance between the side standards 20 to be varied and also to permit removal of the seats: 12 without dismantling the side standards. As shown the side standards 20 are provided with two sets of bearings 76 to permit alternative heights of the seat 12. In place of the springs 66 positive means may be provided for holding the stub shafts in adjusted position. The abutment against which the seat bears when in seating position is preferably mounted on the back 14 and in the case of a seat which is adjustable in height the abutment comprises attachment plates secured to the back 14 by bolts 94 and having a crossbar 92 out of alignment with the bolts 94 so that the reversal of the abutment gives a different height to the operative crossbar 92 of the abutment. The spherical shape of the cooperative bearings permits the side standards to be fixed to the floor so that a curved row of chairs is obtained.. The back 14 is secured to the side standards by means of bolts passing through slots to accommodate for the variable distances between the side standards. Specification 638,508 is referred to.

Title: Improvements in the production of carbon
IPC: C01B31/00
Filed: 1927-02-04
Abstract: 286,845. Johnson, J. Y., (I. G. Farhenindustrie Akt.-Ges.). Feb. 4, 1927. Carbon.-Carbon is obtained from carbon monoxide or a gas containing it by decomposing the carbon monoxide into carbon and carbon dioxide by heating to a high temperature with the addition of a small amount of an organic compound or a carbonyl of a metal which catalytically accelerates the decomposition. Organic compounds, for example the acetyl-acetone compounds, of iron, nickel, and cobalt may be used. The catalyst may be added continuously or at intetrvals. The organic compounds may be dissolved in organic solvents, and sprayed into the gas. In an example, carbon monoxide containing iron carbonyl is passed through a high pressure furnace at a temperature of 400‹ C. and a pressure of 100 atmospheres. The residual gas is washed free of carbon dioxide and, after addition of further carbonyl, is introduced into another furnaces. The carbon obtained contains 2 per cent of iron.

Title: Process and apparatus for cracking hydrocarbons
IPC: C10G9/02
Filed: 1921-01-26
Abstract: 180,719. Davis, C. S. Jan. 26, 1921. Hydrocarbons, cracking.-In a process for cracking petroleum oils in the vapour phase to produce gasoline, benzene, toluene, &c., provision is made for maintaining the feed to the retort, and the temperature and pressure in the retort constant. The oil is fed under air pressure from a tank 1, through a pipe 3, and a preheating coil 53, to an atomizer 4. near the base of a conical retort 2 heated by gas or oil burners 23. An additional material such as superheated steam or oil vapour may be fed from a generator 37, and superheated coil 57 to an opposed atomizer 33. The retort contains a hollow tapering drum 58 adapted to be rotated and to carry scrapers which remove carbon &c. from the inner surface of the retort. The carbon falls into a carbon-pot 96 through valves 99, 98 normally open. When the pot is to he emptied the valves are closed, and the door 97 of the pot is opened. Provision is made to prevent the valve 98 or the door 97 from being opened unless the other is closed. The vapours generated in the retort rise through the space between the retort and the drum 58. The light vapours from the upper part of the retort are drawn down a pipe 122 surrounding the feedpipe 3, and heavy vapours are drawn through the open lower end of the drum by the aspirating action of the atomizer 4. Vapours are withdrawn at an intermediate level by a pipe 13 to a condenser. Pressure is maintained in the retort by a valve 14 whicb may be placed at the inlet or outlet of the condenser. The feed of oil to the retort is maintained constant by controlling the supply of steam to the air-compressing pump 5 through a valve 8 regulated by a diaphragm 9 acted upon at one side by the pressure in the retort and at the other by the compressed air in the pipe 7. The supply of fuel to the burners 29 is regulated by a thermostat 18 through a diaphragm valve 20. The supply of steam to the atomizer 33 is maintained uniform by maintaining a definite level of water in the generator 37 and regulating the supply of fuel to the heaters according to the pressure in the generator. Valves 116 in the oil supply pipe 3 and in the air-supply pipe 7<a> are adapted to be maintained open by the pressure in the retort 2 and to close if the pressure in the retort falls. In a modification the valve 14 controlling the discharge of vapour controls also the supply of oil through the pipe 3.

Abstract: 791,224. Phonographs. INDUSTRIES MUSICALES ET ELECTRIQUES PATHE MARCONI. Feb. 2, 1956 [March 3, 1955], No. 3346/56. Class 40 (2). In a record player having automatic and semiautomatic operation and adaptable with the aid of a centring, record-changing element 7 to play records with a large centre hole, there being a tubular record-distribution control member 10 coaxial with the turntable 4 and means for selecting whether the operation is to be automatic or semi-automatic, an auxiliary stop mechanism includes a device which co-operates with the element 7 and acts in dependence upon the presence or absence of records centred thereby through a mechanical linkage passing through the member 10 to control rocking of a balance beam 19, 20 which is biased so as to render the automatic operation inoperative and the semi-automatic operation operative and when permitted by the actuation of the said device in the absence of a record or records. As shown, slidably disposed within the member 9 which controls the record-distributing system are a pair of push-rods 11, 12, the upper rod 11 being formed with a T-shaped head engaging in elongated slots in identical and diametrically-opposed feelers 15 articulated at 16 on brackets 17 secured to the spindle 7. A balance beam 19, 20 pivotally mounted on a fixed axis 21 exerts by means of the heavier arm 20 thereof an upward thrust on the rods to maintain the latter in end-to-end contact, and at least one record 8 is sufficient to prevent the feelers from projecting externally of the spindle 7. When the last record of a stack has been deposited on the turntable the beam pivots about the axis 21 so that the arm 20 prevents a member 22 from returning to the position which determines the automatic cycle and the cycle becomes a semi-automatic one wherein the pickup arm is lowered to the rest position to switch off the motor of the record player.

Title: Improvements in or relating to the smelting of copper
IPC: C22B15/14
Filed: 1933-02-03
Abstract: To lower the bismuth content of copper matte molten metallic copper is agitated with the molten copper matte and then allowed to settle out: the molten copper collects the bismuth from the matte.  In a method of carrying out the process a molten matte is charged into a converter and blown until a portion of the contents is converted into metallic copper, thorough agitation taking place during the operation.  Blowing is then discontinued and the molten copper allowed to settle carrying the bismuth with it.  The purified matte is poured into a second converter and blown to metallic copper.  In modified methods molten metallic copper or a proportion of copper oxide may be added to the matte; cuprous sulphide reacts with the oxide producing metallic copper. Specification 15222/02, [Class 82 (i)], is referred to.
