Title: Joint separation of acetylene and ethylene from cracked gases
IPC: F25J3/02
Filed: 1967-08-11
Abstract: Joint separation of acetylene and ethylene together with some methane and ethane from cracked gas obtained by a flame burning beneath the surface of petroleum and containing carbon monoxide, hydrogen, oxygen nitrogen, C 3 to C 5 hydrocarbons together with carbon oxysulphide and carbon disulphide is effected by drying and compressing the cracked gas at 2, 4 condensing part of the methane and the whole of the remaining hydrocarbons, C5 2 and COS in a heat exchanger 9, separating them at 10, 11 vaporizing the separated condensate in said heat exchanger 9, compressing the vapour at 15 and thereafter passing said separated fraction under pressure through lines 12, 12b, 19 into a rectification column 6 from which product ethylene and acetylene vapour containing methane and ethane is withdrawn through a line 25 whilst liquid bottoms containing the whole of the C 3 to C 5 hydrocarbons, C5 2 and COS are withdrawn through a line 27. Said liquid bottoms may be returned through a line 29 to the burner of the cracking plant or is vaporized at 28 and returned to the feed line 8 of heat exchanger 9 which latter is cooled by a return flow of uncondensed gases from separators 10, 11 after expansion in a turbine 14. The concentration of acetylene in column 6 is maintained below a predetermined safe level by adding a mixture of methane, ethylene and ethane in a line 20 to the feed in line 19. Exchanger 9 is cooled by vapour withdrawn from separator 10 and expanded in a turbine 14.

Title: A Coupling for Providing a Hermetic Connection.
IPC: F16L59/18
Filed: 1958-11-19
Abstract: A hermetic coupling in a liquid gas transfer line comprises inner and outer duct sections 1, 2, 3, 4 bounding vacuum spaces with the inner ducts 1, 3 inter-engaged and bearing first and second sealing members 5, 7, sealing means 18 between first and second flanges 10, 11 disposed respectively at the end of outer duct 2 and on a sleeve 12 fixed to outer duct 4, bellows 13, 15 bounding spaces communicating respectively with the spaces between the inner and outer duct sections and means co-operating with the first and second sealing members 5, 7 to bound a first chamber 9 communicating with a second chamber 17 disposed between the first and second bellows. When a liquid gas, e.g. helium, starts flowing a slight initial leakage into chamber 9 is evaporated on contact with the walls of the latter and any leakage between the sealing members 5, 7 expands in chamber 17. The pressure rises in chamber 17 and an equilibrium is established between the pressures in ducts 1, 3, chamber 9 and chamber 17. The union elements are of metal joined by welding and the duct sections are of stainless steel.
Patent ES-349481-A1 (ES)
Title: High modulus carbonaceous material and apparatus and methods for making the same
IPC: D01F9/16
Filed: 1968-01-18
Abstract: Carbon fibres having a high modulus of elasticity are prepared by resistively electrically heating to above 2000 C. a short span of a moving continuous strand or web of conductive, amorphous carbon fibres for up to 10 seconds in an inert atmosphere, and simultaneously stretching the fibres in the strand by 10 to 50% of their original length. Non-conductive fibres are preheated to between 400 and 1900 C. in an inert atmosphere either radiantly or resistively electrically, in order to render them conductive. The electrical heating is effected by passing the strand over electrodes, which are preferably of the roller type, so as to complete an electric circuit with the short span of strand or web. Additional systems of rollers are used to stretch the fibres during heating. The stretching may either be effected by applying to the yarn a constant force, or providing a constant stretch.

Title: Film advancing and rewinding mechanism
IPC: G03B19/04
Filed: 1968-01-26
Abstract: In a photographic camera, transport means for winding a strip of film from a supply member past an exposure station to a take up member, and for subsequent re-winding, include an operating member driving a power transmitting element, movable between two positions to wind or rewind the film. As shown in Fig.1, in the winding position, clockwise rotation of a winding knob 42, rotates a shaft 33, and film 14 is wound, from a supply cassette 16 past an exposure position 15, on to a take up core 27 rotated by the engagement of a stud 48, on a gear 46 on shaft 33, with a pin 49 on the core. In the rewinding position Fig.2 (not shown) axial movement of knob 42 away from the camera case 11, disengages the stud and pin, but engages gear 46 with gear 24, so that a further clockwise rotation of the knob rotates cassette 16 anti-clockwise, through gear train 46, 24, 23, 19, to rewind the film. The shaft 33 is maintained in either axial position by the engagement of spring-loaded detent balls 38 in groove 39 or 41 in bore 37 of core 27. The winding knob may be replaced by a lever, or the operating member may be power-operated. A sprocket, driven by the operating member may directly move the film.

Title: Frequency-measuring apparatus for the indication of momentary values of the frequency of a series of impulses,especially for medical purposes
IPC: A61B5/024
Filed: 1968-05-03
Abstract: Apparatus for measuring the instantaneous frequency of electrical pulses representing for example heart beat frequency includes an amplifier circuit 2 (see Division H3) delivering a constant amplitude output pulse for each input pulse, the first pulse enabling a gate 13 to pass clock pulses at, e.g. 1 kc/s. to a first counter 17, the second pulse closing gate 13 and enabling a gate 14 to pass clock pulses at e.g. 100 kc/s. to a second counter 18, the outputs of the counter being compared and a pulse fed to decade counter 27 at equality. This pulse resets counter 18 and the process is repeated until a predetermined number of pulses, e.g. 60,000 have been fed via gate 14, a counter-29 also receiving these pulses then closing gate 14. The number of times counter 18 is reset, i.e. the count in counter 27, represents the instantaneous frequency. This count is preferably displayed. Measurements are commenced and terminated by push-buttons 53, 78 respectively controlling a NAND gate 3 connected to the output of amplifier 2. A simulator button 58 enables a gate 50 so that pulses at a variable frequency may be applied from a simulator 52. Circuitry 64 returns the system to its standby condition if, for example, the second input pulse does not arrive within a predetermined time of the first.

Title: Method of Manufacturing a Rotor Blade.
IPC: B29C70/54
Filed: 1968-08-08
Abstract: A rotor blade comprising a glass reinforced plastics shell and a rigid expanded plastics core is moulded in a two part mould 4, 5 employing half shells 1, 2 of synthetic resin impregnated fabric or roving and an expanded core preform 3 which is of oversize dimensions, in the width and height directions whereby, on closing the two mould halves 4, 5 together whilst heating by electric elements 9, the surface layers of the core preform 3 soften under the mould closing pressure and an even and continuous pressure is applied by the preform 3 to press the shells 1, 2 against the mould cavity. A reinforcement layer 7, of synthetic resin impregnated fabric, may be applied to the loading end 8 of the core preform 3 prior to the insertion thereof between the shells 1, 2. A lead rod 6 is incorporated in the moulding to provide correction for the axis of gravity of the blade. Excess shrinkage of the preform 3 during the moulding process may be avoided by pro-shrinkage thereof.

Patent ES-368478-A1 (ES)
Title: Dampering systems
IPC: F23L11/02
Filed: 1969-06-18
Abstract: Chimney draught is controlled by directing a stream of air centrally downwards into the chimney and deflecting gases rising adjacent the chimney wall towards the centre of the chimney to produce a recirculation of the chimney gases. In a chimney 21 leading from a recuperator 22 in the waste gas off-take of a glass furnace 19, a nozzle directs air downwardly at the centre of the chimney top. An inturned lip on the chimney deflects the rising gases inwardly, and the air delivered from a fan 24 is controlled in accordance with the pressure above the glass in the furnace. A sensor 29 compensates for changes in the ambient atmospheric pressure. The top of the chimney may be surrounded by a wind shield, and the nozzle may be spaced from the plane of the chimney top so long as the stream of control air penetrates beyond the lip at the chimney top.
