IPC: G11C11/06
Filed: 1960-05-20
Abstract: 910,973. Magnetic matrix stores. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 5, 1961 [May 20, 1960], No. 17975/60. Class 40 (9). A magnetic store comprises a matrix of magnetic elements C1 interlinked with digit conductors D1 and word conductors W1, and a series chain of equal resistances R1, one for each digit conductor, connected to a constant current source, a separate switch being provided in series with each digit conductor to connect the conductor across the corresponding resistor. The constant current source consists of a transistor QC whose emitter is connected to the earth point of a voltage source P through a variable resistor VR, and whose base is held at - 3V. The switches preferably consist of transistors Q1 each having a transformer secondary winding T1 connected between its emitter and base. Variable resistor VR is initially adjusted so that with all the switches open the current through resistors R1 is approximately equal to the half-write current. To write a word into the store a word wire W is energized with a half-write current, and pulses are fed to the appropriate transformers T1 to cause certain of the transistors Q1 to conduct. Read-out is achieved by applying a " negative write current " to a word wire to give an output in certain of the output wires (not shown). Transistor Q1 may be replaced by diode gates, transistor QC by a constant current valve circuit, and the magnetic cores by thin magnetic films.

Title: Themo-electric devices
Inventor: WILKINS FREDERICK JOHN
IPC: G01K7/02
Filed: 1963-05-10
Abstract: 1,089,781. Thermoelectric devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 8, 1964 [May 10, 1963], No. 18699/63. Heading H1K. [Also in Division G1] A multi-junction thermoelectric converter comprises at least one helix wound from a continuous length of electrically conductive wire, the same part of the length of each turn of the helix being coated with a material of substantially higher conductivity than the continuous length of wire so that thermo-junctions are formed between the coating and the wire at the ends of each coated length, the cross-section of the helix having at least one apex and one row of junctions being located at this apex, and the helix being supported by at least two rod-like supports, one constituting an electric heater extending along the helix at the apex and another extending along the helix at a position remote from the apex. Preferably the wire is a nickel copper alloy (constantan) and the coatings are of silver, copper, or iron. In one embodiment (Fig. 1) two interleaved helices are wound about a common electric heater 11 and respective copper bars 13, 14, the hot junctions A 1  ... A n  being located on the heater at the apices of the respective helices and the cold junctions B being adjacent the copper bars, from which they are separated by thin paper insulators 15, 16. The whole is mounted in a shielding box 26 made of copper blackened on the inside, and is preferably placed in an evacuated enclosure. In an alternative embodiment (Fig. 8, not shown) a single helix is employed, the cold junctions being embedded in a groove in the base of an evacuated copper housing. If a differential converter is required the helix is supported on two heaters, one adjacent each row of junctions. The heater or heaters may each comprise a single wire or may be of bifilar construction, and the converter may be employed for measuring A.C. currents at audio or high frequencies or in high frequency watt meters. The methods used for making the helices, involving the steps of winding constantan wire on polystyrene formers which are subsequently dissolved away, masking the coiled wire during the application of the copper coating and inserting the supports, are described in detail in the Specification.

Title: Re-liquefaction of gas evolved from a cryogenic tank
IPC: F17C9/04
Filed: 1974-04-29
Abstract: 1413456 Liquefying gas LUMMUS CO 29 April 1974 [27 April 1973] 18710/74 Heading F4P A process for re-liquefying the gas evolved from liquefied ethylene stored in a cryogenic tank T (LE)  at about atmospheric pressure, comprises passing the gas to a fractionating condenser 46 where it is brought into indirect heat transfer relationship with gas evolved from LNG which has a lower boiling point than ethylene, stored in at least one further tank. During transport in a ship (Fig. 1, not shown), gas evolved in tank T (LE)  is led via lines 34, 38, 40 to condenser 46, whilst gas from the LNG tanks is passed to condenser 46 via lines 68, 66, 70. After passing through heat exchange tubing 74 in condenser 74, the natural gas is passed via line 76 and compressor 80 to a line 82 leading to the ship propulsion unit. Ethylene which is re-liquefied and forms at the bottom of condenser 46 is passed by pump 122 back to the tank T (LE)  via lines 120, 124. Conversion from ethylene storage to LNG storage.-After all the tanks have been emptied it might be necessary to convert the tank from one which stores ethylene to one which stores LNG. In this case, residual vapour in line 66 from the LNG tanks is divided into two parts, one small part being passed via lines 112, 110 to tank T (LE) , and the rest passing to condenser 46 via line 70. Due to ethylene being heavier than natural gas, the ethylene vapours are displaced to the bottom of tank T (LE)  and are withdrawn via lines 154, 156 and passed to condenser 46 via lines 34, 38, 40. Condensed ethylene is collected from the bottom of condenser 46 and passes to a liquefied ethylene holding tank 132 via lines 120, 126. Trace impurities are collected overhead and passed to the propulsion unit via lines 84, 88, 90, 76. When the tank T (LE)  has 75% natural gas, the stream taken from line 154 is passed through lines 34, 38 and 58 to a reboiler 63 where the methane is stripped off before the ethylene gas passes to line 40 and back into condenser 40. Conversion from LNG to ethylene storage.-If tank T (LE)  has been used for LNG storage and residual natural gas is left therein, then liquefied ethylene from holding tank 132 is passed via lines 138, 148 to vaporizer 160, and thence via line 162 to tank T (LE)  where it is liquefied due to the cold generated by the natural gas. As pressure increases, gases are withdrawn via lines 34, 38, 40 to condenser 46. Minor quantities of ethylene in such gases are returned via lines 120, 124 to tank T (LE)  while the major overhead portion passes to the propulsion unit. When - 170‹ F. is reached supply of ethylene vapour ceases and the tank is allowed to warm to - 1.50‹ F. whereupon the remaining liquid ethylene in tank 132 is passed by pump 140 via lines 146, 154 into tank T (LE) . In all cases the gases from tank T (LE)  and the other tanks may, if their pressure is not high enough, be passed to the condenser 46 via compressors 52 and 98 respectively.
