Patent GB-521891-A (GB)
Title: Improvements relating to the polymerization of olefinic hydrocarbons
IPC: C07C2/18
Filed: 1938-10-11
Abstract: 521,891. Polymerization of olefines. RUTHRUFF, R. F. Oct. 11, 1938, No. 29443. Addition to 518,749. [Class 2 (iii)] Olefines are polymerized by passing them at elevated temperature over a catalyst comprising as an essential ingredient, copper pyrophosphate. The copper pyrophosphate may be prepared (1) by mixing equimolar solutions of sodium pyrophosphate and of a soluble copper salt (the sodium salt being 10 per cent. in excess of the equivalent amounts), removing the precipitate and drying ; (2) by adding the sodium pyrophosphate in an amount equal to only about 90-100 per cent. of the equivalent amount and then proceeding as in (1). As an alternative method, a reduction promoter may be added to the solution of pyrophosphate-such reduction promoters as copper, zinc, the zinc-copper couple, aluminium, aluminium activated with copper, and mercury. Thus zinc dust may be added in an amount equal to 0.5 to 5 per cent. of the copper present. In an example, 111.5 grams of sodium pyrophosphate in 2,500 ccs. of water are added to 125 grams of copper sulphate in 1,375 ccs. of water, rapidly with stirring. The mixture is stirred for one hour, filtered, washed with water, and dried at 225‹F. for 24 hours. A mixture of butane and butylene containing approximately 28 mol per cent. of n-butylene and 12 mol per cent. of iso-butylene is passed over this catalyst at a rate of 35 cubic feet per pound of catalyst per hour under a pressure of 1,400 pounds per square inch. The temperature is 325‹ F. and in the first 8-hour period 2¢ weight per cent. of liquid was obtained ; during second 8-hour period 11¢ per cent. ; third 8-hour period 29 per cent. Total yield after 400 hours 99 gallons of liquid per lb. of catalyst used. An excess of copper salt over the amount equivalent to the pyrophosphate may be used, thus using reagents twice as concentrated as in the example, 10 per cent. excess of the copper sulphate may be employed. Catalysts prepared according to (1) or (2) may be used mixed together in any proportions or (2) may be used alone. It is advisable to bind the catalysts before use. Thus the powdered catalyst may be mixed with about 5 per cent. finely divided acid tar, pelletted, and baked at 600-700‹F. for 24 hours. If desired the acid tar binder may be dissolved in a suitable solvent such as chloroform or benzol to facilitate incorporation in the catalyst.

Title: Improvements in or relating to television pick-up tubes
IPC: H01J29/02
Filed: 1949-11-18
Abstract: 687,940. Cathode-ray tubes. TOWNSEND, F. H., and CATHODEON, Ltd. Nov. 9, 1950 [Nov. 18, 1949], No. 29530/49. Class 39(i) In a television pick-up tube of the high velocity scanned type having a charge storage surface capable of storing energy in the form of a charge pattern corresponding to the light distribution in an optical image, a thermionic source of electrons for emitting electrons towards the storage surface, and means for accelerating the emitted electrons towards the storage surface so as to charge the storage surface negatively, the thermionic source comprises a plurality of thermionic cathodes arranged around and in front of the storage surface, means being provided for individually adjusting the electron emission from the respective cathode, whereby the concentration of electrons directed upon different parts of the storage surface may be adjusted to obtain a predetermined selective negative charging of different parts of the storage surface. As shown the pick-up tube comprises an evacuated envelope containing a semitransparent photo-cathode 2 and a storage target spaced therefrom consisting of a mica sheet 3, which may be coated with a material to make it highly secondary emissive, backed with a conductive layer 4 forming the signal plate. Photoelectrons released from the photo-cathode 2 by an optical image projected thereon are accelerated towards the storage surface 3 by the wall coating 7 which is at a positive potential and are focused upon the storage surface by the focusing coil 8. The storage surface is scanned by a high velocity beam from the electron gun 6, and a collector electrode 9; which may be a wall coating, collects secondary electrons released from the storage surface 3. Four thermionic cathodes 10 are disposed around the area defined by the storage surface 3, being spaced in front thereof and so positioned that they do not interfere with the formation of the electron image on the surface 3, nor with the scanning by the cathode-ray beam. The collector electrode 9 is maintained positive with respect to the cathodes 10 and directs and accelerates the electrons released therefrom towards the storage surface with such velocities that the surface is negatively charged, a grid electrode 12, maintained at a positive potential also controlling the acceleration. Alternatively the electrode 9 may be omitted and its function performed by the electrode 12. The emission from the--cathode 10 is individually adjusted to obtain the desired negative charging on the storage surface. In the case of an iconoscope the electrons would irradiate the photo-sensitive mosaic target instead of the secondary emitting target of the image iconoscope.

Filed: 1963-07-26
Abstract: Granules substantially composed of carbon and suitable for use in microphones are prepared by forming a dispersion of cellulosic and/or hemicellulosic material in water, regenerating the material from the dispersion and subjecting the dried regenerated material in bulk form to heat treatment at a temperature in the range 750 DEG  to 2600 DEG C. in an inert atmosphere, the temperature being raised from ambient temperature to a temperature in the range 350 DEG  to 450 DEG  C. during a period of at least 48 hours and when the material is at least partially carbonized to such an extent that the final product will consist of granules of sizes in the range 150 to 500 m  in diameter. The aqueous dispersion is prepared as described in Specification 860,342 or Specification 889,351 and the regeneration and drying steps may be carried out as described therein or as in Specification 959,905.  The granulation of the material may be carried out in a rod melt with steel rods or in an impact mortar.  In an embodiment of the invention, the regenerated material is heated over at least 48 hours to a temperature in the range 350 DEG  to 450 DEG  C., this stage being carried out under super-atmospheric pressure if desired.  The material is cooled to ambient temperature and broken into granules which are then subjected to heat treatment in the range 750 DEG  to 2600 DEG  C., water-washed and dried.  The entire heating procedure is conveniently carried out in an inert atmosphere, e.g. N2 or A and the carbonized granules produced may be treated at 400 DEG  to 1000 DEG  C. in a CO2 atmosphere.  Microphones incorporating the granules are of particular use in telephone transmitters.

Title: Improvements in magnetic memories
IPC: G11C19/08
Filed: 1965-07-15
Abstract: 1,109,006. Circuits employing thin magnetic films. AMPEX CORPORATION. 15 July, 1965 [4 Aug., 1964], No. 30117/65. Heading H3B. A shift register comprises a series of anisotropic magnetic thin film storage sites 25, 32, 26 arranged alternately in two rows so that neighbouring sites, which may or may not be contiguous, can interact magnetically at their adjacent corners. The easy axis is transverse to the longitudinal axis of the rows. Switching in input site 25 is by domain rotation but in the other sites switching is by domain boundary movement and is possible only if the neighbouring preceding site has an opposite magnetization. A respective drive winding 22, 24 is common to all the sites of a row. The input site has a data input coil 54 and the last site (26 as shown) has a read out coil 65 and a sense coil 70, arranged as shown to minimize noise. A binary 1 or 0 may be written into input site 25 by energizing coil 54 with a pulse simultaneously with a positive or negative half cycle in winding 22. Winding 24 is energized 180 degrees out of phase with winding 24 so that information is stepped from site 25 to site 32 on the next appropriate half cycle. Read out is by energizing coil 65 with a spike pulse coincident with a positive half cycle in coil 22. The polarity of the induced signal in coil 70 is representative of the binary information read out. The invention may be formed by depositing on a glass substrate (14), Figs. 1 and 3 (not shown), successive layers of permalloy (12), SiO insulator (20) and copper or aluminium conductors (22, 24). The composition or thickness of the magnetic film may be varied at the interacting corners. An alternative form is described with reference to Fig. 8 (not shown) wherein the sites have a non- rectangular parallelogram configuration.
