Title: Cooling continuous casting having high degree of axial symmetry - by more intense cooling of separate axially symmetric surface regions
Inventor: BIRAT JEAN-PIERRE
IPC: B22D11/124
Filed: 1980-02-12
Abstract: In the sec. cooling of a continuously cast metal prod. part of the periphery of the prod. is subjected to a higher degree of cooling, this part comprising two non-consecutive regions which are symmetrical wrt. the axis of the prod. In the case of a prod. with an approx. square cross-section, the regions are two opposite side faces of the prod. The method is esp. useful in the cooling of continuously cast steel ingots . The non-uniform cooling results in a more diffuse region of high segregation and internal porosity, which is similar to that obtained in castings having a low degree of axial symmetry.

Inventor: DETRIER STEPHANE
IPC: B65G59/10
Filed: 1980-03-18
Abstract: The invention relates to a device for distributing bottle caps having a chain, which is composed of successive shapes, starting with a chute in which the said caps are stacked. The object of the invention is to improve a distributing device in such a way that it satisfies the various practical requirements more effectively than has been the case hitherto. The object is achieved in that the device includes a rotating drum with arms, the ends of which are set in such a way that they are able to pick up and deposit a bottle cap, and also means for moving each arm so that its end can remove a bottle cap from the stack and move it in accordance with its geometrical axis, further means for modifying the positions of the arms so that the bottle caps can be easily inserted into the shapes and yet other means which are provided to ensure that a bottle cap cannot be deposited in a shape which still contains another cap which has not been placed on a bottle.

Title: Composite insulated structural panels for building dwellings - having foam or mineral wool between layers of cement and plasterboard
IPC: E04C2/288
Filed: 1980-07-11
Abstract: Composite panels for domestic buildings include a strong, weatherproof surface, a layer of thermal insulation and a smooth internal surface where the external layer is of resin-bonded concrete and the insulating layer is of mineral wool or foamed rigid or semi-rigid resin superficially impregnated by the cement on one face. The resin bonded cement is cast in a shallow mould and overlaid with the insulating material prior to setting (by e.g. stoving at 60 deg.C for 20 mins.). Opt. such a cement/foam combination is inverted on to another layer of cast cement to partly impregnate and coat the opposite face of the insulation; alternatively the insulation may previously have been bonded on one face to a layer of plasterboard covered with a base or decorative paper on its opposite face. The prefabricated structure eliminates need for sectional assembly on site, esp. skilled hand lay-up of impermeable surface layers or introduction of insulation into narrow cavities. Combines fire resistance with thermal and acoustic insulation and integral decoration. Tolerant of minor spatial shifts between the two solid layers.

Patent FR-2480558-A1 (FR)
Inventor: BARKER MALCOLM
IPC: A01D78/12
Filed: 1981-04-15
Abstract: A haymaking machine with at least one raking head, rotatable about an essentially vertical axis, possesses a control mechanism, by means of which the position of the rake tines can be varied during a revolution of the rake head. An improved control mechanism contains an eccentrically arranged rotatable ring (26) which carries connecting rods (28) extending radially outwards. These connecting rods are coupled to arms (35) at the inner ends of the tine carriers (23). This coupling is made via a connecting system (30) having a pivoting connection (31), pivotable about a fixed point (32), and a connecting rod (34) which extends between the pivoting connection (31) and the arm (35). The connecting system (30) converts a smooth and continuous rotational movement, which is derived from the ring (26), into a virtually intermittent movement, as a result of which the tines on the one hand have a longer dwell time in the vicinity of the ground and on the other hand are lifted off from the ground more suddenly than would occur in a pure sinusoidal movement exerted, without any further change, directly on the tines. The ring (26) can be rotated about a collar (25) which is itself adjustable in order to vary the eccentricity of the ring in relation to the axis of rotation of the head.

Title: Valve arrester protecting AC, DC power network from overvoltage - has arcing horns between turns of single helical blade forming walls of arc extinction chamber
Inventor: ASINOVSKY ERIK IVANOVICH
IPC: H01T1/04
Filed: 1981-05-29
Abstract: The valve arrester comprises a serial arrangement which includes at least one nonlinear resistor and spark gaps implemented as arcing horns which are housed in slit-type arc extinction chambers whose walls are made of an electric insulation material. The walls are implemented in the form of a single helical blade arranged on a centra cylindrical member and adapted to produce a single helical arc which is formed from arcs struck in the spark gaps during the arrester breakdown. The arcs being joined together during their movement. The arcing horns are situated between the turns of the helical blade, assuming a helical space orientation, and being affixed to the surface of the central cylindrical member. The nonlinear resistor should be inserted between the adjacent spark gaps and is shunted at the point in time when a single arc is formed, thus providing for an increase in the arrester carrying capacity.
