Filed: 1961-06-29
Abstract: 935,882. Carburetting apparatus. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES. June 29, 1961 [July 29, 1960], No. 23572/61. Classes 7(2) and 7(3). In carburetting apparatus for internalcombustion engines comprising at least two carburetters, each having an independent source of fuel, alternatively feeding a normal running circuit and a slow running circuit, in which latter a primary mixture of air and fuel is formed, the individual slow running circuits of each carburetter are fed by air mainly through a common passage 15 the section of which is adjustable by means of a single regulating member 17. The pressure losses may be identical in the various ducts connecting the single regulating member to the various carburetters. A calibrated orifice which in each carburetter delivers rich mixture is adjustable but means are provided for preventing its setting from being changed as long as the carburetter is mounted on the engine. The invention is applicable to cases where the carburetters are supplied not with liquid fuel but with a gaseous fuel. The needle valves 12 may be replaced by non- regulatable jets.

Abstract: 508,821. Automatic control systems; cut-out systems. BORMANN, O. Aug. 10, 1938, No. 23623. Convention date, Aug. 11, 1937. [Class 38 (iv)] [Also in Group XXXVII] Temperature-The vapour pressure 'in an electron-discharge vessel 1 is maintained substantially constant by automatic control of a cooling agent in accordance with temperature and load current. Thus the effect of an element 6, sensitive to wall temperature, upon a switch 8 is modified by a heating coil 11 energized in proportion to load current. The arrangement may be such that the controlled temperature is reduced with increasing loads. The switch may close contacts 9 whereby a saturating winding of a choke 23 is energized, this choke controlling the saturation current in choking coils 13 in the circuit of a fan motor 2 ; the motor circuit may be controlled with or without a relay e.g. by vacuum switches. Upon excessive load, contacts 10 may be closed to energize the opening coil 15 of a circuit breaker 4.; the material of the rod 6 may be so chosen as to determine the relationship between switching-off time and overload. Modifications are described and illustrated in which (a) the rod 6 is in part in the secondary winding of a current transformer connected in the anode circuit, (b) a bimetallic element forming a loop secondary of a.transformer lies upon the switch lever operated by the rod 6 and, carrying the switch contact, modifies by its flexure the operation of the switch, and (c) mercury contact-thermometer and Bourdon-tube type elements on or passing through the vessel wall and having their outer portion heated by a current coil.

Abstract: 1,073,224. Timed control of electric circuits. IAN NICKOLS Ltd. June 12, 1964 [June 17, 1963], No. 23981/63. Heading G3T. An electrical timed switching device comprises a cam 1 mounted on a spindle 2 so as to be rotatable by a reversible constant speed electric motor (not shown). Disposed about the spindle 2 are four micro-switches A, B, C and D, each having an arm 3 which, when struck by the cam 1 operates the switch contacts. Switch A is the starting point of the cycle, B corresponds to the shortest preselected time, C to the medium time, and D to the longest time. B6, C6 and D6 are sockets for selecting the required time delay. A relay 7 is associated with the device and has contacts 7A, B, C, D and E and arms 7F, G and H. A live contact 8 is connected to contacts A4 and arms 7F, C and H. Switches B, C and D are connected in parallel to leads 9 and 10. Contact 7A is connected to lead 10, contact 7B to "motor reverse" control, contact 7C to "motor forward" control and contact 7D to an apparatus to receive a signal, e. g. a post office type uniselector. In operation the medium contact C6 is selected, for example, and cam 1 depresses switch A breaking the lead 8 and 11. Arm 3 of switch C is undepressed and current flows from C6 through C4 to lead 9 and to 7E through 7H and 7C to drive the motor forward. Cam 1 is rotated and arms 7F, 7G and 7H are connected to terminal 8 through switch A. Cam 1 actuates switch C and current flows from C6 via C5 and lead 10 to solenoid 7J, arm 7G moves to 7B to reverse the motor, arm 7F moves to 7A and arm 7H moves to 7D to emit a signal. Cam 1 returns to switch A and de-energizes solenoid 7J and arms 7F, 7C and 7H revert to their original position to stop the emitted signal. The rotary cam 1 may be replaced by a linear striker. The switches may be moved with respect to a stationary cam. A subsidiary circuit may cause a signal to be emitted at any time intermediate the start and finish of a complete cycle.

Title: Manufacture of steel
Inventor: COOK LESLIE
IPC: C21C5/32
Filed: 1960-07-11
Abstract: A process for the manufacture of low-phosphorus, high-carbon steel from molten pig-iron comprises blowing the molten iron from above continuously or intermittently with oxygen or oxygen enriched air containing, for at least a part of the blowing time, a dephosphorising agent in suspension, and maintaining the carbon content of the melt at not less than 0.2% by one or more carburising operations in which a carbonaceous material in suspension in a carrier gas is blown in below the surface of the melt.  The dephosphorising material, e.g. lime, may all be added in the blast, or a portion may be added directly to the melt and the remainder in the blast, and the blow continued until the melt has a carbon content of 0.6% and a phosphorus content of 0.13%. The slag may then be removed and the carburisation performed by blowing graphite, anthracite, coke or coal in powder form in suspension in a carrier gas, e.g. nitrogen, or carbon dioxide or a mixture of either with air or carbon monoxide, below the surface of the metal until the carbon content is 1.2% and the phosphorus is 0.14%.  The process is completed by blowing with oxygen containing the dephosphorising material until the carbon is 0.53% and the phosphorus 0.035%.  The carbonaceous material may be added at the same time as the oxygen and dephosphorising material after deslagging but the carburising blow should finish sufficiently before the end of the process to allow a final oxidising blow.

Title: A method and machine for forming a tubular workpiece
IPC: B21J7/14
Filed: 1958-07-28
Abstract: 890,012. Forging. APPEL PROCESS Ltd. July 28, 1958 [Dec. 6, 1957], No. 24162/58. Class 83 (4). In a method of forming a tubular workpiece by feeding it incrementally through an axially fixed die throat, wherein the dies act radially upon the work and in out-of-phase relation with the feed motion, a mandrel having successive portions of different diameters and with some portions shorter in length than the corresponding portions of the workpiece is used, the workpiece being alternately fed relative to the mandrel and together with the mandrel and the dies being moved inwards progressively and radially after each incremental advance of the workpiece until such repetition of the steps completes the required form of the work. A workpiece 10, Fig. 3, is formed with a series of different diameters and tapers defined by numerals 11-14, using a mandrel 20, Fig. 2, having portions 21, 23, 25 of a length considerably less than the corresponding lengths of portions 11, 13, 15 of the work. Machines of the type disclosed in Specifications 768,834 and 797,518 may be used to swage the work and to feed the work and mandrel together relative to the dies or alternatively to feed the work relative to the dies and mandrel. The mandrel may in fact be stationary, may move forward more slowly than the work or may even move in a reverse direction. In forming the workpiece 10 the end of portion 11 is aligned with the end of portion 21 of the mandrel and both work and mandrel are incrementally and intermittently advanced in out-of-phase relation with the action of the swaging dies for a distance of about 1¢ inch, due to elongation of the workpiece about 2 inches of the portion 11 will be formed. The mandrel then stops while the work is moved incrementally on 1 inch accompanied by ¢ inch elongation. The 4 inch long portion 11 is then completed by moving mandrel and work together incrementally for ¢ inch. Portion 12 of the work is then swaged incrementally moving mandrel and work together. The remaining portions of the work are then formed either in several steps as for the portion 11 or in one step as for the portion 12. Specification 829,122 and French Specifications 1,074,439 and 1,137,761 also are referred to.

Abstract: 918,226. Fluid pressure brakes. CITROEN S.A., ANDRE. July 5, 1961 [July 5, 1960], No. 24283/61. Addition to 832,030. Class 103 (1). [Also in Group XXXVII] An anti-skid device for vehicle brake systems having an electric means for interrupting brake operation comprises a switch 16 driven with the wheel so as to close contacts not only when the wheel locks but also when the acceleration is above a predetermined value, such that braking is not restored until the wheel has again substantially achieved road speed. The system has a main accumulator 10 feeding a front brake accumulator 12 and a rear brake accumulator 2. Depression of pedal 7 causes valves 14 and 5 to put the accumulators in communication with their respective brake cylinders but an electromagnetically-controlled valve 18 (connected to the normally-open switch 16) is inserted in the supply line to the rear brake cylinders 1. The switch 16 is closed when the wheels tend to lock and the valve 18 interrupts the supply to brake cylinders 1 and puts them in communication with a discharge tank 19. This allows the wheels to accelerate causing switch 16 to close a parallel contact (see Group XXXVII) and prolong the interruption of braking.

Patent GB-730486-A (GB)
Title: A process for separating ketones from mixtures thereof with other compounds
Filed: 1952-09-29
Abstract: A ketone is separated from a mixture containing the ketone and an alcohol having a boiling point within 20 DEG  C. of that of the ketone by a process comprising passing the mixture in the vapour phase over a hydrogenation-dehydrogenation catalyst at a temperature above 220 DEG  C. and at a pressure below 110 lbs./sq. in. so that the alcohol is converted to a ketone which is different from the original ketone and any unsaturated component having a boiling point within 20 DEG  C. of the original ketone is saturated, and separating the ketones present in the resulting mixture by distillation.  The process is applicable, for example, to the mixture obtained by the Fischer-Tropsch synthesis and to the mixture obtained when a ketone is reacted with an alcohol to form a higher ketone.  These reaction mixtures may be treated in their entirety by the process or they can first be fractionally distilled and certain cuts may then be treated. Suitable hydrogenation-dehydrogenation catalysts are, for example, certain metals and metallic oxides.  Brass, i.e. any alloy of copper and zinc, is the most suitable.  The process provides a continuous method of producing a higher ketone from a lower ketone and an alcohol which comprises reacting a lower ketone with an alcohol in a first zone containing a catalyst having dehydrogenating and dehydrating properties, e.g. a copper/alumina catalyst, to produce a higher ketone and an alcohol with a boiling point within 20 DEG  C. of that of the ketone, subjecting the mixture to the process of the invention and recycling the lower boiling ketone separated by distillation to the first reaction zone.  In the examples: (a) methyl isobutyl ketone and methanol are reacted in the presence of a copper/alumina catalyst; the resulting mixture is fractionally distilled and the portion containing the C6-alcohol and C7-ketone is heated in the presence of brass to give a mixture which is distilled to give as separate fractions C7-ketone and C6-ketone; (b) methyl isobutyl ketone and methanol are reacted over a copper/alumina catalyst to give a mixture containing the C7-ketone; the mixture is fractionated to give a cut boiling between 125 DEG  and 175 DEG  C. which is heated in the presence of brass; the resulting mixture is distilled to give a cut containing C7-ketone with some C8-ketone.
