Title: Joint for plastics coated metal pipes - has socket end radially deformed to compress thermoplastic joint ring
Inventor: VAHLBRAUK KARL HEINZ
IPC: F16L58/18
Filed: 1976-06-18
Abstract: The end of the plastic coated pipe (1) is enlarged to form the socket (3) and the extreme end (3a) is rolled over to retain the O ring (4). The end edge of the pipe is split into a number of small tongues (3c). The mating pipe (2) is also plastic coated and is provided with a tapered sleeve (5) made of a thermo-plastic elastomer which resists hydrolysis. The pipe (2) is inserted into the socket end (3) of the pipe (1) and then radially deformed by a hydraulically powered tool as shown on the right-hand side of the diagram. The tapered sleeve (5) thus forms a firm bond between the pipes.

Title: Determining of spherical graphite elements - from perturbation produced in reactivity by presence of element
Inventor: DAOUD HASSAN DIPL PHYS
IPC: G21C17/112
Filed: 1976-10-23
Abstract: Determn. of the temp. of graphite elements, esp. spherical elements is effected using a measuring (calibrating) reactor; the graphite elements are each continuously conducted through a central duct of the reactor, thus passing through zones in which neutron-scattering or neutron-moderating material has a max. influence upon the reactivity of the reactor. The effect of this is to produce a position-dependent reactivity perturbation as each graphite element passes through. The dependence of the reactivity perturbation (em), which is produced at the position (m) of maximum neutron flux, upon the temp. (T) of a graphite element is first used to calibrate the measuring reactor by the measurement of a graphite elements of known temp. The reactivity perturbation (em) which occurs at position (m) as a graphite element under investigation passes this point is then measured. Using this value, the temp. of the graphite element is then calculated using the equation: em(T) = A + AlT + A2T2, (where the constants A, Al and A2 are known from the calibration measurements). Uses is made of the fact that, if a curve of reactivity perturbation is plotted against distance of travel through the core, a min. occurs at the position of max. neutron flux, and that a functional relationship exists between the value of the reactivity perturbation at this point and temp. of the graphite element which produces the perturbation.

Title: (alpha)alumina catalyst carrier prodn. - by impregnating active alumina with metal salts and firing
Inventor: BUNDA TSUCHIO
IPC: B01J21/00
Filed: 1976-11-18
Abstract: Alumina-base catalyst carrier is produced by impregnating an active alumina variety (X, O, delta u or gamma-form) with a slat capable of reacting with alumina to form a spinel structure, and firing to convert the alumina into the alpha-form. The salt is pref. a nitrate, sulphate, or chloride of Mg, Ni, Co, Mn or Zn. The catalyst carrier acquires the toughness and refractivess of alpha-alumina whilst retaining the large pore volume and specific surface area of the active alumina. The product is not brittle, even when kept under water for a prolonged period of time (in contrast to the conventional alpha-alumina). The product can also withstand prolonged vibrations when used as a 'petrol-reforming' catalyst for internal combustion engines.

Title: Two-for-one twisting spindle assembly - has permanent magnets at end of pivoted holding arm and in spool sleeve
Inventor: HEMALA ZDENEK
IPC: D01H7/86
Filed: 1977-01-11
Abstract: In a two-for-one twister, the spindle has permanent magnets to hold the spool carrier at rest. An initial set of permanent magnets is located at the upper end of the spool carrier, at the opposite end from the disc, or inserted as a keyed unit in the spool sleeve. A holding arm above the ballooning limit shroud carries a second set of permanent magnets. The holding arm is mounted on a pivot axis so that it is attached to a fixed section of the machine, but can also swing clear above the ballooning limit shroud. The design gives a two-for-one yarn twisting spindle which can be mfd. economically for feed spools of large dia., uses metal for all the load-bearing parts, allows high spindle speeds and which gives a long useful life.

Title: Mechanical watering of farm fields - using rotary sprinkler system with rotating arm transported along centre line of field
IPC: B05B3/02
Filed: 1977-02-18
Abstract: The mechanical watering of farm fields is achieved by transporting a rotary sprinkler system with a rotating spray arm on a centre line of the field at a spacing from the field longitudinal edge corresponding to the thrower radius. The sprinkling on one of the field transverse edges with a sprinkler set to semi-Circle sprinkling is limited to sprinkling of a semi-circle in the transport direction. After passing through a section corresponding to the thrower radius it is automatically changed over to full circle sprinkling. After running on the centre line, before reaching the other field transverse edge, at a distance from this corresponding to the thrower radius, it is automatically re-set to half circle sprinkling for sprinkling the semi-circle opposite to the transport direction.

The contaminated rinsing water is pref. fed into the metal treatment bath via d istn. plant which concentrates the liq. No contaminated rinsing water leaves the system, e.g. no drain water arises which could cause environmental pollution; and only a small amt. of fresh water is required.
Patent DE-2729311-A1 (DE)
Title: Gearwheel-turbine power plant - has pressurised fluid from reactor expanded by fluid immersed meshing gears
Inventor: BREUHAMMER HORST
IPC: F02B45/00
Filed: 1977-06-29
Abstract: The power plant uses energy obtained from a cracking reactor, which is passed through a catalyser to a fluid-immersed gearwheel turbine. After expansion in the turbine, the flow is diverted from the reservoir in which the turbine is immersed to a regenerator unit. The fluid is supplied through pipes to a point at which the gears are fully meshed. The fluid moves radially outward from each gearwheel hub to ports in the gearwheel which are opened in succession as the gear turns. The fluid is expanded as the gears move out of mesh, producing useful work. Fluid under pressure is additionally fed to side ports in the rotor casing from an integrator unit. The fluid is exhausted to the reservoir through ports in the casing wall.

Title: Centrally-controlled telephone PBX - has special growth buttons allowing more line groups to be introduced without modification
Inventor: SEHR WERNER ING GRAD
IPC: H04Q3/62
Filed: 1978-02-27
Abstract: The telephone private branch exchange makes use of existing centrallised devices to alter the number of line groups that can be reached. Different numbers of line groups can be selected from the operator's console by operating a special button.

Title: Engine for large model aeroplane - has two standard two=stroke engines joined in opposed unit by output gearbox
Inventor: BUSCHER ALFRED
IPC: F02B75/34
Filed: 1978-04-04
Abstract: Two standard two stroke engines for models are mounted in line opposite each other. A T-shaped connecting piece between them contains a gear wheel train. The crank-shaft of each engine turns a gear wheel and both of these wheels drive a common central gear. This in turn drives a gear on the shaft of the propeller of the model aeroplane. The two engines give two firing strokes per revolution and thus produce a more even turning moment. The gears increase the propeller speed and this reduces propeller vibrations.
