Title: An improved process for the conversion by destructive hydrogenation of solid carbonaceous materials into valuable liquid products, especially benzines
IPC: C10G1/00
Filed: 1931-10-05
Abstract: <PICT:0380615/III/1> In the destructive hydrogenation of solid distillable carbonaceous materials in two or more stages, a smaller amount of hydrogen relative to the amount of carbonaceous material present is used in the second stage than in the first stage, the reduction being greater than that due to the consumption of hydrogen in the first stage.  The quantities of hydrogen are preferably 4-20 and 1-4 cubic metres per kilogram of material in the first and second stages respectively.  The materials may be preheated, made into pastes with heavy oils, and mixed with pulverulent catalysts, e.g. oxide or sulphides of groups 6 and 8 or solutions of catalytic salts. The amount of hydrogen in the second stage is reduced by withdrawing part of the hydrogen used in the first stage or by increasing the amount of carbonaceous materials or by using a separate circulation of hydrogen.  A constant level of liquid is maintained in the second stage by withdrawal and recirculation of the materials.  The second stage may be followed by further stages with further reduction of hydrogen or the products may be destructively hydrogenated in the vapour phase.  Finely divided pit coal impregnated with ammonium molybdate is fed from a charger W through a reaction vessel B by revolving plate members. Hydrogen is passed in counterflow from a heater A and the products are passed through a dust trap X to a separator C from which vapours and gases pass through a cooler E to a high pressure separator F where benzines and middle oils are condensed, while the hydrogen is separated and passed through a purifier G and then is divided into two parts one being returned to the heater A while the remainder is mixed with the products from the separator C and the mixture re-treated in a heater J and reaction vessel K which is supplied through a pipe L with a colloidal catalyst comprising 80 parts of molybdic acid, zinc oxide, and magnesia and 20 parts of tungsten sulphide made into a paste with heavy oil and is heated to 460 DEG  C.  The products are fractionated in a column O where they are separated into heavy oils removed through the bottom of the column, middle oils removed through a pipe R and benzines which are passed through a cooler P to a receiver Q.  The middle oils may be further treated by passing them with additional hydrogen through a heater S to a reaction tower T containing tungsten sulphide, the resultant products being cooled and collected in receivers U, V.  Specifications 359,945 and 379,335 are referred to in the Provisional Specification.

Title: Improvements in or relating to automatic speed regulation of rotating machinery
IPC: H02P7/06
Filed: 1934-10-01
Abstract: 444,823. Automatic control of speed. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and STEWART, C., 49, Mansfield Road, Luton. Oct. 1, 1934, No. 28067. [Class 38 (iv)] When a master relay 1, subject to the speed of a rotating machine, energizes a contactor A to cause a reversible motor 21 to effect a speed correction by any suitable means, an operating relay 5, also subject to the said speed, energizes a contactor X to cause a reversible motor 30 to change the setting of the operating relay, which thus opens in advance of the completion of correction, whereupon the contactor X causes the motor 30 to change the setting of the operating relay in the reverse direction to cause resumption of the correcting action of the motor 21, and the process is repeated until the speed is fully corrected and the relays 1, 5 are restored to equilibrium. These effects are obtained by the connections shown in Fig. 1, the contacts of the relays and of contactors A, B and X, Y being shown in the positions they occupy in normal speed conditions. Any function of speed may be used to actuate the relays, e.g. a voltage from a pilot generator, or magnetic drag on a disc ; centrifugal relays of mechanical or hydraulic type may be used. Where the machine is capable of direct electrical control, as in the case of a shunt wound motor the speed of which is controlled by varying resistance in its field circuit, the relays X, Y may have additional contacts X4, Y4, to accelerate the correction by operating, for example, on the field 41 in the manner indicated in Fig. 2 or its equivalent. The setting of the operating relay may be changed, e.g. when the relays are responsive to the voltage of a tachometric generator, by causing the motor 30 to act upon a, resistance in series with the relay coil. A modification of the arrangement shown in Fig. 1, and illustrated in Fig. 4 (not shown), employs a single relay subject to tachometer voltage and controlling the relays A, B, the setting of which is changed in this way by an element operated by the motor 30, which also operates a contact co-operating with two fixed contacts controlling the respective contactors X, Y. A time delay may be introduced into the correcting action of the motor 21 by providing the contactors X, Y, Fig. 1, with additional normally -closed contacts in the circuits of the motor 21 and making the contacts X, Y, normally-closed ; the motor 21 then operates only after the first action of the motor 30. A similar time delay may be provided in the arrangement according to Fig. 4. All the arrangements described have provision H for manual control of the speed, and resistances in the motor circuits to determine the speed of their actions ; these resistances may provide for different speeds in opposite directions. Reference has been directed by the Comptroller to Specifications 307,046, [Class 38 (iv)], 349,478, and 405,665.

A tubular assembly, particularly for tent poles, comprises two tubes and a connecting piece consisting of a front part 3, and a rear part 2 divided by a shoulder 1. The rear part may have a recess 4 for weight reducing purposes and has an axial groove 5. The front part 3 has an axial groove 6 opening into a depression formed by axially sloping sides 8 and a surface 7 of cylindrical shape arranged eccentrically on the connecting piece to define a sloping surface to act as a cam. The first tube has an internal protrusion adapted to be received in groove 6 and to engage surfaces 7, 8 when the tube and connecting piece are relatively rotated, thus locking the tube in position. The second tube has an internal welded lip received in groove 5 and is a force fit on the rear part 2 of the connecting piece. The first tube may have a larger internal diameter than the external diameter of the connecting piece since the camming surface 7 acts to bring the tube inner surface into contact with the connecting piece.
