Title: Matrix storage device
IPC: G11C7/04
Filed: 1969-04-08
Abstract: 1,264,033. Magnetic storage arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 April, 1969 [10 April, 1968], No. 17893/69. Heading H3B. In a word ordered matrix storage device, information is stored in a word row H 1 -H 3  either direct or inverted dependent on the state of a random noise driven bi-stable trigger FF 1  connected to input gates B 1 -B 4 , and at least one auxiliary core K 1ta , K 1tb  ... is provided in each row to record the form of storage. The matrix uses two cores K 11a , K 11b  ... per bit, the cores of each pair being arranged in opposite magnetic senses with respect to the information conductors V 1-4 , so that coincident word and information pulses produce a higher partially switched magnetization in one core than in the other. As trigger FF 1  is, on average in time, as many times in one state as the other, each core of a pair is, on average, in the higher magnetization state as often as the other core and hence temperature differences between the pair due to repetitive response to the same digit are eliminated. Trigger FF 1  is connected to the auxiliary cores by a conductor V t , and during read-out the signal from the auxiliary cores is fed through read amplifier RA t  to drive a trigger FF 2  into a state corresponding to that of FF 1  when the information was recorded. Output gates D 1-4  are connected to trigger FF 2  so that information through read amplifiers RA 1 -RA 4  invariably appears non-inverted at output conductors E 1-4 . The cores are only partially switched to enhance working speed.

Title: Process for the preparation of artificial resins and oleoresins
IPC: C08G8/30
Filed: 1922-06-29
Abstract: Artificial resins and oleo-resins are prepared by heating phenols or naphthols with terpene hydrocarbons in the presence of a catalyst. Suitable catalysts are (1) strong acids, e.g. hydrochloric, hydrobromic, hydriodic, hydrofluoric, sulphuric, nitric, phosphoric and its anhydride, oxalic and sulphonic, particularly p-toluene sulphonic, acids; (2) salts, viz. anhydrous aluminium, ferric and zinc chlorides, silicated or siliceous earths; (3) chlorine, bromine and iodine.  The products comprise mixtures of phenol ethers, terpene phenols, i.e. phenols with terpene radicles substituted in the nucleus, and polymerization products of terpenes; but in certain cases it is stated to be possible to prepare individual substances. Examples are given of the preparation of a phenolic ether by heating carvene and b -naphthol in the presence of a little p-toluene sulphonic acid to a temperature below 160 DEG  C., and of the preparation of a terpene phenol by maintaining a mixture of carvene and phenol at about 105 DEG  C. in the presence of p-toluene sulphonic acid.  Examples are also given of the preparation of resinous bodies by heating phenol and carvene in the presence of zinc chloride or bromine.  In all cases, the products are steam distilled and then purified.ALSO:Artificial resins and oleo-resins are prepared by heating phenols or naphthols with terpene hydrocarbons in the presence of a catalyst.  These resins can be readily emulsified with water in the presence of alkalies or alkali carbonates and give stable emulsions, even when resin solvents such as toluene are present, which are useful for degreasing and cleaning purposes.

Title: Rocket motor
Inventor: BRAGG STEPHEN LAWRENCE
IPC: F02K9/56
Filed: 1959-05-28
Abstract: 906,840. Rocket propulsion. ROLLS-ROYCE Ltd. May 20, 1960 [May 28, 1959], No. 18209/59. Class 110 (3). A rocket motor comprises a thrust chamber, a gas-containing chamber, means for ensuring that the pressure in the gas-containing chamber depends on the pressure in the thrust chamber and on the acceleration of the rocket, a source of reference pressure, means for comparing the pressures in the gas - containing chamber and the source of reference pressure, and thrust control means controlled by the pressure-comparing means. Fig. 4 shows two thrust chambers each with its own control system and also a means of balancing the thrusts. Each thrust chamber, Fig. 1, communicates via a restriction 16 with a chamber 20 normally vented to atmosphere; the restriction is also connected to a cylinder containing a piston 19 on the other side of which is connected a bottle 26 of nitrogen. Movement of the piston controls the flow of oxidant to a gas generator 11 where gas is generated to drive turbine pumps supplying fuel and oxidant to the thrust chamber. Acceleration of the rocket causes a beam 23a, Fig. 4, to move against a spring to close the vents 21, thus increasing the pressure at 16 and reducing the oxidant flow to the combustion chamber. The pressures in the thrust chambers also act on the beam by way of opposed pistons 42, 43, so that the pressures are kept equal. A barrier gas may be used to prevent gases spreading from the thrust chamber throughout the system. In another embodiment, Fig. 5, Me or Nz is supplied at constant pressure via a regulator 58<SP>1</SP> and is exhausted to the thrust chamber via an acceleration-sensitive valve in a chamber 20c and a constriction; acceleration opens the valve and the increased gas pressure in line 15d reduces oxidant flow to the gas generator, a reference pressure being provided at 25a; the reference pressure may be obtained by letting gas from 58<SP>1</SP> flow to atmosphere through a line tapped between two restrictions by line 25a.
