Title: Nuclear power station - combined water cooled and organic cooled reactor
IPC: G21C1/00
Filed: 1971-12-23
Abstract: Saturated steam from the water cooled reactor heat exchanger passes to the organic reactor heat exchanger where it is raised to superheat conditins. Fuel from the water cooled reactor is transferred to the organic reactor after partial burn-up. The theoretical advantage of the concept lie in lower turbine costs with improved operational performance, lower fuel investment from the maximising of fuel burn-up, low construction costs of organic reactor ensuing from its lower operating pressure.

Title: Pre- and post-coital contraception - with implantation -inhibiting steroids
Inventor: WOTIZ HERBERT H DR MED
IPC: A61K31/57
Filed: 1972-01-12
Abstract: Contraceptive agent for pre-coital use in males or post-coital use in females has an implantation-inhibiting content of oestriol, oestriol triacetate, 18-homooestriol, 16-epioestriol, 11 beta-hydroxy-oestradiol, 16 alpha-oestradiol, 6 alpha-hydroxy-oestradiol and/or 7 alpha-hydroxy-oestradiol. The named steroids (so-called inhibitory oestrogens) inhibit the endometrial growth necessary for implantation and thus prevent implantation of the fertilised ovum and therefore pregnancy. The pre-coital male contraceptive effect is considered to be due to transport of the contraceptive compound into the uterus in or with the spermatozoa, rather than to inhibition of spermatogensis.

Title: Accurate active magnetic surfaces for small cores - are produced by machining after casting core in potting mould
Inventor: LEHMANN KARL-OTTO PROF DR
IPC: H01F41/00
Filed: 1973-08-27
Abstract: Cores with accurately machined low loss and distortion free surfaces are employed, for example, in tape recorder heads. To facilitate the machining of the surfaces of the stress relieved core it is cast in a mould complete with its windings and screening can if required. The casting material is synthetic resin loaded, for example with a granular aluminium powder, to give good heat conduction. The casting resin prevents movement of the core during surface machining and conducts away the heat generated during this operation. Casting is typically done under vacuum conditions.

Title: Aesthetic fluids prepn - from water soluble resin solutions having non-Newtonian characteristics
Inventor: LEWELLEN WILLIAM B
IPC: B01F23/47
Filed: 1973-12-10
Abstract: An optically contrasting liq. suspension is produced by the introduction of discrete mass of water-soluble resin gel a second mass of a similar gel hving a different colour or other optical property so that an optical boundary is produced at the interface between the two gels. The gels both have high fluidity limits" i.e they must be subjected to a certain minimum shear stress before any flow takes place, and therefore retain their original shapes indefinitely under normal conditions. Pigments in the form of insoluble particles having a dia. between molecular size and 0.63 mm can be used to create the contrast. The suspensions are used in cosmetic preparations and advertising displays. Typical gels are produced by dissolving carboxyvinyl polymers in water and adding pigments, air bubbles, ball bearings (which will not sink) etc.
Patent DE-2405735-A1 (DE)
Title: Flushing plant sequence control - has return valves to storage tanks interlocked with inlet valve relays
IPC: G05D21/02
Filed: 1974-02-07
Abstract: A flushing plant for the successive introduction of water and of an alkaline or acidic cleansing agent into a system for the treatment of liquids is controlled by a first control section which indicates by lock-in relays which inlet valve has been opened. The valve for the other agent is automatically blocked. When a conductivity sensor has confirmed that a set conductivity is reached, a return valve is opened by another relay to return the fluid into the correct storage tank. This system is not tied to a fixed cyclic program, yet it ensures that the cleansing fluid is always returned to its own storage tank.

Abstract: 1440285 Error correction INTERNATIONAL BUSINESS MACHINES CORP 24 April 1974 [4 June 1973] 18002/74 Heading G4A Data is stored on a plurality of independently accessible storage units, e.g. magnetic tape cartridges, and check bits, each of which is a function of a corresponding bit from each data storage unit, are stored on a check unit which may be used, in the event of a catastrophic loss of data on one of the data storage units and detected by an error checking facility associated with that unit, to restore the data on that unit. Extension of the system to include more than one check unit, each of which stores the check bits for one position of a Hamming code, is also mentioned. In normal operation, one of the data storage units is selected and data thereon is updated by read before write heads 15, 21. The difference e jk  between each old bit and the corresponding new bit is EXORed with the corresponding old parity bit p k  from the check unit to update the parity bits. The parity bits are initially recorded by successively (or simultaneously) reading the data storage units to record the modulo 2 sums of the corresponding bits, and data restoration is similar reading from the good data storage units and the check unit.
