Title: Process for the removal of carbon dioxide from gases
IPC: C10K1/16
Filed: 1962-11-28
Abstract: A process for the removal of CO2 from a gas which is free or substantially free from H2S comprises contacting the gas with a selective solvent comprising a sulphone of general formula <FORM:0957260/C3/1> wherein at least four of the groups R are hydrogen atoms and any remaining groups R are alkyl groups having from one to four carbon atoms.  The sulphone may be sulpholane (thiophene tetrahydro-1,1-dioxide), 2.3-, 2.4-, or 2.5-dimethyl cyclotetramethylene sulphone, 3-ethyl cyclotetramethylene sulphone, and 2-methyl 5 - propylcyclotetramethylene sulphone. The solvent may be modified by the addition of 1 to 10% of a low boiling liquid, e.g. hydrocarbons having 8 to 12 carbon atoms, water, or alkanolamine. The contacting pressure of the gas with the solvent is preferably greater than 7 kg./cm.2, and the temperature is preferably between 10 DEG  and 65 DEG  C.  The gas may be contacted countercurrently with the sulphone solvent under pressure in a vertical tower of trays or baffles, or in a tower constructed as a rectified contacting zone maintained with a temperature difference between the top and bottom. The treated gas leaving the tower near the top and the fat solvent leaving the tower at the bottom.  The resulting fat solution is then cooled and passed to a stripper at reduced pressure.  Suitable gases for treatment by this process include refinery and natural gases, hydrogen-containing gases, e.g. as obtained in catalytic reforming processes, or in the partial combustion of hydrocarbons with oxygen-containing gases.

Title: Fluid control valve and method for manufacturing the same
IPC: B23K20/08
Filed: 1972-09-29
Abstract: 1365452 Valves ASAHI KASEI KOGYO KK 29 Sept 1972 [1 Nov 1971] 45070/72 Heading F2V [Also in Division B3] A valve seat and/or valve member has a plate of hard alloy (primarily including Fe, Ni, Co and/or Cu) attached to it explosively so that the depth of interface is in the order of the grid spacing of the atoms. One method of making such a valve member comprises filling the recesses 25 of the member with sand &c. and providing a cover-plate 26 spaced from which is the alloy plate 23 and an explosive 27. On firing the explosive with detonator 28 the plate is brought into metallurgical adhesion with the valve member. Due to the yieldable property of the sand, the plate sheers around the recess. The alloy plate may be attached to a base-plate of the same material of the valve member and then the base-plate welded thereto. Other variations of these methods are described.

Title: Speedometer
IPC: G01P3/04
Filed: 1967-10-05
Abstract: 1,155,658. Measuring angular speed, electrically. KIENZLE APPARATE G. m. b. H. Oct. 5, 1967 [Oct. 21, 1966], No.45397/67. Headings G1K and G1N. In a tachometer, a transmitter 1 (e.g. coupled to a vehicle gear-box) produces a pulse train proportional to angular speed, which is applied to bi-stable flip-flop circuit 3 the output of which drives a step motor 4. A friction disc 28 is driven by a constant speed step motor 25 to provide a reference speed. Motor 4 drives a sun-wheel 7 of a differential gear unit 8 and a sun-wheel 9 being initially stationary, planet wheels 10 and a crosspiece pot 12 are rotated thereby, teeth 11 on the rim of pot 12 rotating a gear 13 and pinion 15 to move a rack 16. A friction wheel 23, carried by the rack is displaceably mounted in a slot 22 in a shaft 21 of the sun-wheel 9, and is moved radially across the face of the friction disc 28 as the rack is moved thus providing a steplessly adjustable gearing, the speed at which wheel 23 is rotated by the disc increasing with distance from the disc centre. As the rotation speed of wheel 23 and shaft 21 increases, the adjusting movement of rack 16 becomes slower and is finally zero when the reference speed and input speed are equal, and the indicator 17 will remain stationary. A recording arm 18 with stylus 19 is fitted to the rack 16. In an alternative embodiment Fig. 2 (not shown) the friction disc of the reference speed motor has a spherical surface which drivingly engages the friction wheel, and the said motor is pivotal about a fixed shaft by means of a link attached to the rack thereby enabling adjustment of the friction wheel speed. Also instead of the differential there is a worm and pinion transmission.

Abstract: 1306468 Multiplex radio signalling INTERNATIONAL STANDARD ELECTRIC CORP 30 Sept 1971 [3 Oct 1970] 45533/71 Addition to 1306467 Heading H4L The television transmission system disclosed in the parent Specification is modified in that a time-compressed audio signal is transmitted between the end of each frame and the start of the next frame of a colour signal as the lower sideband of the colour subcarrier frequency and the co-operating receiver includes a synchronous demodulator controlled by the subcarrier frequency. The received signal is demodulated at 1 and fed to a contact b and via amplifier 2 to a contact a of a switch 3. A counter 4, as in the parent Specification, is supplied with the horizontal and vertical deflection pulses and produces a signal which via line selector 5 controls switches 3, 6, 7 so that during the period of the line transmitting the desired time-compressed audio signal the switches are connected in the opposite position to that shown. Thus the sound signal is applied to the synchronous demodulator 8, which receives also the colour subcarrier frequency from oscillator 9, and the output of the demodulator is supplied via filter 10 to the store 11 under the control of high frequency pulses F T . At the end of this line period the switches are returned to the position shown and the sound signal is read out at the slow clock frequency f T . During the frame period of the video signal the chrominance signal is demodulated at 8 to operate the picture tube.

Title: Process for the preparation of aliphatic ªÏ-cyanocarboxylic acids
IPC: C07C/
Filed: 1964-11-13
Abstract: Aliphatic o -cyanocarboxylic acids are prepared by heating an aliphatic o -dicarboxylic acid together with an amount of ammonia equivalent to one carboxyl group or less either as free ammonia or in the form of a substance that splits off ammonia under the reaction conditions, or the monoammonium salt of an aliphatic o -dicarboxylic acid either alone or in the presence of the free acid at 140 DEG  to 220 DEG  C. until the evolution of gas ceases and then heating the reaction mixture to 240 DEG  to 350 DEG  C. until the evolution of gas which has recommenced ceases again.  The o -cyanocarboxylic acid can be recovered from the reaction mixture by dissolving said mixture in dilute ammonia, extracting the neutral substances therefrom with a water-immiscible organic solvent, subjecting the residual ammoniacal solution to steam distillation, and extracting the cyanocarboxylic acid from the remaining solution by dilution with water or extraction with a water-immiscible organic solvent.  The addition to the initial reaction mixture of 5 to 10% by weight of the o -dicarbonitrile corresponding to the o -cyanocarboxylic acid to be produced and based upon the weight of o -dicarboxylic acid present in the starting material either in the free form or as the mono-ammonium salt, is stated to practically completely eliminate the formation of the o -dicarbonitrile as by-product.
