Title: Process for the Removal of Sulphur from Natural Gas and the like Gases
Inventor: DENT FREDERICK JAMES
IPC: B01D53/48
Filed: 1966-11-10
Abstract: 1,192,739. Removing sulphur-containing impurities from gas streams. GAS COUNCIL. 6 Nov., 1967 [10 Nov., 1966], No. 50514/66. Heading C1A. Sulphur compounds are removed from natural and like gases by continuously flowing the gas, preferably after admixture of hydrogen and/or steam, in contact with active iron cobalt or nickel suitably prepared by reducing a coprecipitated nickel-alumina catalyst. The active metal bed is generally maintained at 250-400‹ C., and, although the active metal is a catalyst for the decomposition of the methane present in the gas, the process is operated under such conditions that the methane is substantially unaffected. The gas to be treated generally contains no more than 6%, preferably no more than 3%, ethane or equivalent hydrocarbons higher than methane and is brought into contact with the active metal at not higher than 350‹ C. in admixture with up to 0À1 vol. steam/vol. gas. As exemplified, the sulphur compound is tetrahydrothiophene.

Abstract: 1473929 Transistor amplifiers WESTERN ELECTRIC CO Inc 21 Nov 1974 [23 Nov 1973] 50594/74 Heading H3T An amplifier 20 with a short response time for sensing the states of semi-conductor memory cells, produces an intermediate signal having differential components IS, #, and a differential output signal, and includes an output transistor, e.g. Q3, having first and second emitters E1, E2 connected to be responsive, respectively, to one of the said intermediate components IS and to an input signal DJ, such that the currents in E1 and E2 vary in phase with each other. In an embodiment a differential input DJ, DJ is applied to an emitter coupled pair Q1, Q2 which produces the intermediate components IS, IS, output transistors Q3, Q4 being cascade coupled to Q1, Q2. To obtain a short input rise time without making resistors R4, R6 so small that power dissipation becomes large, transistors Q3, Q4 are provided with third emitters E3 connected to R4, R6 so that portions R4a, R6a are of low resistance compared with portions R4b, R6b. With this arrangement the input resistances of the amplifier are relatively independent of the values of resistors R4b, R6b, so that the latter may be relatively high to limit the current to V EE . The purpose of transistors Q5, Q6 is to clamp the collectors of transistors Q3, Q4 respectively to a potential (V cc -1À5 V BE ) when Q3 or Q4 is highly conductive. Output stage 30 converts the balanced signal from amplifier 20 to an unbalanced signal at terminal TO. Circuit 30 is gated for connection to TO by a forward biasing signal on ER combined with a reverse biasing signal on #.

Abstract: 1405151 Piezoelectric elements KUREHA KAGAKU KOGYO KK 3 Nov 1972 [5 Nov 1971] 50878/72 Heading H1E [Also in Division H4] A piezoelectric electroacoustic element, which may be used to transmit or receive acoustic waves, comprises a sheet 1 (Fig. 1) of piezoelectric polymer material, preferably molecularly oriented, having on one face thereof a backing 3 of material of greater Young's modulus and mass than the sheet 1. The other face of the sheet 1 is for transmitting or receiving acoustic waves. The sheet 1 has vacuum-deposited electrodes 2, 2<SP>1</SP> of aluminium, gold, copper or graphite. Backing 3 is a plate of metal, graphite earthenware or porcelain. If the backing 3 is made of conductive material it may be attached directly to the sheet 1 (Fig. 2, not shown) or adhered by conductive epoxy resin. The polymer material is preferably polyvinylidene fluoride or a copolymer of vinylidene fluoride with tetrafluoroethylene, trifluoroethylene, vinyl chloride, chlorotrifluoroethylene, vinylidene fluorochloride or propylene hexafluoride. Electrode 2 has as small a mass as possible. Molecularly oriented piezoelectric sheet may be obtained by stretching. It may be an electret made by applying a D.C. potential of 700 KV/cm. for 30 mins. in a chamber of 90 degrees and then cooling the sheet to toom temperature while still applying the D.C. potential. High piezoelectric conversion is believed to be due to the fact that deformation of the sheet is in the direction of its thickness in use.

A force sensitive transducer consists of a stack of apertured Piezo electric discs, each of which 35, Fig. 4, generates a voltage between its plane surfaces when stressed and has metal electrodes 39, 40 deposited or coated thereon, adjacent discs being arranged so that contacting electrodes have the same polarity as one another. Each disc has at least one aperture which may be central, and the electrodes 39, 40 are respectively connected to annular metal deposits 37, 43 on the opposite face, by means of metal coatings on the wall 41 of the aperture, and on the periphery, 44 of the disc. The electrodes on each disc are insulated from one another by non- coated annular portions 38, 42.

The end-plate (52) alternatively may be insulating, and carry a coating (57) of for example gold, on its outer curved surface. Each disc, alternatively, may have two coated apertures Fig. 3 (not shown) serving as positive and negative terminals respectively, insulating non-coated annuli (6) again being provided to isolate the electrodes. The discs of the stack are held together by high vacuum welding, or by being pre-stressed and coated with silicon varnish, the discs being arranged with their axes of minimum thermal expansion coefficient in alignment.

Abstract: 1,247,705. Automatic speed control. WESTINGHOUSE ELECTRIC CORP. Nov.4, 1968 [Nov.20, 1967], No.52084/68. Heading G3R. Constant tension is maintained in wound material by energizing the winder motor with an input signal proportional to the back e.m.f. of the motor and inversely proportional to the linear speed of the material. A signal representing the linear speed of the material is derived from a tachometer 18 and applied to one input of a differential amplier A1, the output of which is fed to a reversible motor 30 driving ganged potentiometers 16, 36, 111. The other input to the amplifier is a signal representing the back e.m.f. of winder motor M but reduced according to the position of slider 24 of the first potentiometer 16. The result of this is that the motorized potentiometers take up a position representing the ratio of back e.m.f. to linear speed which, the Specification establishes, is proportional to the ratio of the diameter of the wound material, D, to the motor field flux, #. The second potentiometer 36 provides a reference signal I, proportional to D/#, to a current regulator 61 which controls the current in the armature of motor M according to the reference signal. A compensating signal IC is also applied to the regulator to alter the armature current during acceleration or deceleration of the mill. The signal IC is provided by a differentiator 60 receiving the linear speed signal from tachometer 18, a function generator 70 employing a motorized potentiometer whose position is determined by the diameter of the wound material, and the third section 111 of the first motorized potentiometer 30. The back e.m.f. signal is derived from the applied armature voltage V corrected for resistance drop IaRa. The field of the motor is normally fully energized but the field is weakened by a regulator 114 at high winding speeds.
