Title: Improvements in or relating to the treatment of food substances
IPC: A23L3/26
Filed: 1953-12-31
Abstract: For increasing the shelf life of foods having a rind, skin, shell or like partially protective covering, decay-causing organisms are inactivated in only a small fraction of the food including all the exterior surface by bombardment with penetrating ionizing radiation such as high velocity electrons.  The food may before such bombardment be enclosed in a film which is impervious to the passage of micro-organisms but pervious to the radiation, e.g. oranges may be sealed in plastic sacks or may be lacquered.  Energy levels of 500,000-1,000,000 electron volts, and electron doses of 50,000-700,000 rep (1 rep is the equivalent of 100 erg./g.), preferably administered at 20,000 rep/sec., are referred to. Specification 657,295 is referred to.ALSO:For increasing the shelf life of foods having a rind, skin, shell, or like partially protective covering, exemplified by most fruits, vegetables and fish, eggs, nuts, seeds, and animal carcasses, decay-causing organisms are inactivated in only a small fraction of the food including all the exterior surface by bombardment with penetrating ionizing radiation such as high velocity electrons produced by a cyclotron.

Title: Improvements in or relating to low temperature gas mixture separation processes
Inventor: DENTON WILLIAM HAVELOCK
IPC: B01D7/02
Filed: 1957-11-25
Abstract: 893,057. Cold separation of gas mixtures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 12, 1958 [Nov. 25, 1957], No. 36616/57. Class 8(2) In a process for separating deuterium from a crude hydrogen mixture by rectification following freezing out nitrogen and carbon monoxide in a line 2, Fig. 2a, of aheat exchanger 1 having counterflowing pure hydrogen line 3 or in a line 5 of a heat exchanger 4 having a counterflow pure hydrogen line 6 in the event of line 2 of exchanger 1 being derimed, deriming is effected by passing pure outflow hydrogen through the congested line of the offstream exchanger in the direction of feed and allowing said line to warm up to the temperature at which feed mixture normally enters the line. In operation and assuming exchanger 1 to be or stream and exchanger 4 to be in process of being derimed, crude mixture at 51‹K enters line A, traverses an open valve 9, line 2, open valves 17, 18 and is discharged at 22À5‹K through a line B to the rectification column from which outflow hydrogen passes into a line D at 21À5‹K, through an open valve 19, the line 3, a valve 8 at 50‹K leading to a discharge line C. This outflow hydrogen is warmed by heat from a turbo-expander (not shown), and is fed to a line K and through a valve 15 to the warm end of line 5 to effect vaporization of congealed nitrogen and carbon monoxide, and the contaminated outflow hydrogen traverses a valve 20 and is discharged through a line J. Immediately prior to switching the feed mixture from line 2 to the derimed line 4 the latter is cooled by a reverse flow of cold purified feed mixture leaving line 2 and being directed through a valve 21, Fig. 2b (the valve 18 being closed), the line 5, a valve 14 and a line leading to an open valve 22 and to the line B. Line 5 having been cooled, feed mixture is directed therethrough by opening valves 13, 18, Fig. 2C, and closing valves 9, 22 whilst outflow hydrogen is directed through line 6 in counterflow to the feed mixture by opening valves 23, 12 and closing valves 19, 8. The so-wormed outflow hydrogen leaves by line C and after having been further warmed in the turbo expander enters line K and is directed through line 2 by opening valves 11, 16 and closing valves 17, 20; the contaminated outflow hydrogen leaving through line J. Specification 869,412 is referred to.

Filed: 1956-11-30
Abstract: 799,945. Digital electric calculating-apparatus; electric digital-data-storage apparatus. STANDARD TELEPHONES & CABLES, Ltd. Nov. 30, 1956 [Dec. 6, 1955], No. 36680/56. Class 106 (1). A data processing system wherein information is read from any storage position on a rotary storage device such as a magnetic drum, processed and the processed information is entered into the said storage position, is characterized by an intermediate storage system comprising two storage devices controlled by an electronic switch to receive processed information alternately so that in one rotation of the drum the processed information is entered into one storage device and the information processed during the previous rotation of the drum and stored in the other storage device is transferred to that position on the drum from which the corresponding unprocessed information was taken. Information is read from a magnetic drum 1 by the read/write head 3, processed in the arithmetic unit 4 and, according to the position of the electronic switch 5 which reverses once each rotation of the drum, the processed information is stored in one or the other of the two intermediate storage devices 6, 7. The processed information is transferred during the next rotation of the drum to the position from which the original information was read. When the same storage position is to be scanned in two successive drum rotations means are provided to transfer the once processed information directly to the arithmetic unit for further processing instead of to the drum. These means comprise an electronic switch 11 actuated by a comparator device (Fig. 2, not shown), which compares every two successive addresses which are to be scanned on the drum, and is adapted to actuate the switch 11 whenever these two addresses are the same.

Title: Improvements relating to apparatus for detecting infra-red radiation
IPC: B61K9/06
Filed: 1955-12-22
Abstract: 793,208. Detecting infra-red radiation. GENERAL ELECTRIC CO. Dec. 22, 1955 [Dec. 30, 1954], No. 36732/55. Drawings to Specification. Class 40 (3). Apparatus for detecting infra-red radiation, of use for example for detecting the passing of a railway vehicle having a hot or overheated journal box, is arranged not to be influenced by the sun's radiation by the inclusion of a filter to eliminate radiation of a wavelength shorter than 5 microns. The filter may be of the silver chloride type. A second filter comprised of silicon monoxide is also included to eliminate radiation from the sun having wavelengths in the 9-11 micron region. In practice a lens constructed of arsenic trisulphide having a spectral passband extending from 1-13 microns is also included so that the overall response is restricted to wavelengths in the bands 5-9 and 11-13 microns. The second filter may be formed as a thin coating of silicon monoxide on the lens. The detector element comprises a conventional bolometer connected in a normally-balanced bridge circuit, the output from which extends via a transformer to an amplifier and suitable indicating or recording devices. The transformer serves to block the standing D.C. output from the bridge but transmits the pulse produced when a hot object passes within range of the apparatus and causes the bolometer to unbalance the bridge.

Title: Improvements in or relating to Radio Direction Finders
IPC: G01S3/74
Filed: 1962-09-27
Abstract: 1,178,111. Radio direction finding. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 27 Sept., 1963 [28 Sept., 1961], No. 36805/62. Heading F4D. In a radio direction finder, for receiving and displaying simultaneously pulse signals from several transmitters, the signals from a selected transmitter may be analysed in respect of pulse length, or pulse repetition frequency. Each transmitter is represented by a spot on a CRT screen, the radial distance of the spot from the screen centre being a measure of the signal strength, the spot angular position representing the signal direction. A second, or strobing, spot is produced which is moved until it coincides with a spot corresponding to the transmitter, the signal from which is to be investigated. The deflecting voltages from both spots are applied to a switching system which automatically supplies the signals, from the selected transmitter only, to the analysing circuit when the voltages are equal. In the case of moving transmitters, the analysis of the received signals may be performed when the transmitter and strobe spots on the CRT screen are not coincident. In this case, the analysis is made when the spot deflecting voltages fall within specified limits. The received signals are displayed on the double beam tube 18 and the strobing signals are applied from the unit, 23. The comparison circuits 31, 32 provide output signals to render the gate, 36, conductive when the received signal on lead 19 is within predetermined limits of the corresponding strobing voltage. Similarly, the compression circuits 33, 34 operate similarly in response to the received signals at 20 and when both gates 36, 38 are conductive the signals to be analysed are applied to 27.

Each row of data (control, &c., and character), termed a "pseudo video scan line" comprises a self-contained packet of digital information which is transmitted in the time of one conventional television line, the information being sufficient to provide for the display of thirty-two characters in each row, sixteen such rows forming one "page". The information in each "pseudo video scan line" controls the display of between eleven and thirteen actual television scan lines on which the characters are produced in a 7 x 9 dot matrix form. Also, in addition to synchronizing, control and address data, error check information and "permission' information, i.e. information allowing the terminals to receive one or more selected groups of information, is included. The character information may be of any conventional type, e.g. news, weather, stock market, advertizing &c. and an override condition is included which allows emergency information, e.g. a civil defence warning, to be displayed at all terminals. The displays may be in colour..

A method of bonding ferrous articles to magnesium or magnesium base alloy articles in the solid state, e.g. to make composite sheets or strips, comprises providing the ferrous article with a thin surface of a coating metal which is soluble in magnesium, e.g. nickel, copper, silver, cadmium, aluminium, tin, zinc, berylium, cobalt, lead or silicon, placing a solid article of magnesium against the surface of said ferrous article having said coating metal, heating said assembly to cause the coating metal to diffuse into the magnesium in an atmosphere of an inert gas, e.g. helium, neon, argon, crypton, zenon or mixtures thereof and at a temperature below the melting-point of magnesium and urging the articles together to achieve solid phase bonding at the interface. The surface of the ferrous article is cleaned by wire brushing, sandblasting or pickling by dipping in a 15% aqueous solution of hydrochloric acid. The metal coating is applied by an electroplating step and the thickness of the coating may range from 0.0001 to 0.0010 inches. The magnesium article is cleaned by dipping in hydrochloric acid, washing in water and air drying and its surface is scratched with a wire brush. In an example a sheet of steel is degreased and plated with copper to a depth of 0.0002 inches by immersion for 10 minutes in a copper cyanide solution. A sheet of magnesium cleaned and scratched is placed against the copper coating. The sheets are clamped together and heated in a chamber containing an inert gas to a temperature within the range 600‹ to 1200‹ F. The assembly is allowed to cool within the chamber. The method may be carried out continuously in which case the articles are passed between rolls in an inert atmosphere at a temperature within the above range.

Title: Improvements in or relating to the manufacture of polymeric materials
Inventor: GUDGEON HERBERT
IPC: C08G18/60
Filed: 1955-12-30
Abstract: A process for the manufacture of polymeric materials by the catalytic interaction of polyesters or polyesteramides and polyisocyanates is characterized in that there is used as catalyst a quaternary ammonium salt.  Preferred salts are those wherein no aryl radical is directly attached to the quaternary nitrogen atom. Suitable are N - benzyl - N - ethylpiperidinium chloride, N : N - dibenzyl piperidinium chloride, carbethoxymethyl - triethylammonium chloride, N - benzyl - N - ethylpiperidinium bromide and N - benzyltriethylammonium bromide. Internal salts, for example betaines can also be used.  The catalysts can be used in the two-stage process described in Specification 767,578, or a similar process employing adducts of polyisocyanates with, for example, esters, phenols, tertiary alcohols or secondary amines. During the second stage there may also be added (as proposed in Specification 785,882), a substance which will react with a polyisocyanate to form a thermolabile adduct.  The quaternary salt can be added at any stage of the process.  In examples: (1) to (3) a polyester from adipic acid and ethylene glycol is heated with (1) 1 : 5-naphthylene diisocyanate in the presence of N-ethyl-N-benzyl-piperidinium chloride and phosphoric acid at 110 DEG C. and subsequently in a mould at 150 DEG  C. to effect curing; (2) p-phenylene diisocyanate in the presence of benzyl-triethylammonium bromide and salicylic acid; (3) 3 : 31-dimethyldiphenyl-4 : 41-diisocyanate in the presence of N - benzyl - N - ethylpiperidinium bromide and salicylic acid.  In Examples (4) and (5) a "raw rubber" by interaction of a polyethylene adipate and naphthylene-1 : 5-diisocyanate and having a Williams Plasticity Number of 443 is cured by heating under pressure with 1 : 5-naphthylene diisocyanate in the presence of (4) N-ethyl-N-benzyl-piperidinium chloride, and (5) cetyl trimethylammonium bromide.

Title: Improvements in or relating to methods of forming insulating coatings on conducting members
IPC: H01J9/08
Filed: 1957-12-02
Abstract: To form an adherent insulating coating on a conductive member, such as a heating filament of an indirectly heated incandescent cathode of an electron discharge device, the member has first deposited on it a coating of aluminium oxide, as by electrophoresis from a dispersion in alcohol, and is then placed in a mist of a solution in a volatile solvent, e.g. methanol, of an insulating substance which lowers the sintering temperature of aluminium oxide, e.g. aluminium nitrate, and firing the member, e.g. at 100 DEG  to 200 DEG C., to cause the insulating substance to diffuse through the aluminium oxide.  One or more further applications of aluminium nitrate may be made to the fired member, e.g. by immersion in or spraying with a solution in methanol of aluminium nitrate, the member being fired at 350 DEG  to 450 DEG C. after each additional application.
