Title: Laminated plastics cover sheet - made by pressing a resin soaked fibrous sheet against a resin free fibrous sheet (BR 21.2.78)
Inventor: DEGENS ALFREDO
IPC: B32B7/02
Filed: 1978-02-17
Abstract: A flexible laminated fibre resin sheet, partic. used in surfacing fibreboard or chipboard, is made by impregnating a first fibrous sheet with a thermosetting resin and hot pressing the first sheet against a second, resin-free fibrous sheet. Pressing is effected such that resin from the first sheet partially penetrates the second sheet and bonds it to the first sheet to form a composite having one hard resinous surface, and one fibrous, resin-free surface. A sheet which is flexible enough to store and which does not exhibit strike through when bonded to the surface of a board. Also any defective sheet can be ascertained and discarded before bonding to the board. Also bonding to the board can be effected at a low temp. and pressure.

Title: Energy prodn. from earth heat in lithosphere - involves shaft insertion, positioning of steam generator at shaft base and feeding water to generator and steam to surface via shaft
IPC: F03G7/04
Filed: 1978-02-27
Abstract: The principle is aimed at obtaining continuous usable energy without derogatory effect on the environment, and involves the positioning of steam generators in the earth's lithosphere which will be activated by the heat capactiry of the planet. The generators produce steam from water or other fluids which in trun is used to drive electrical current generators. The process hinges around the production and insertion of shafts to a depth of several thousand metres, with the steam generators attached to their base, each shaft serving in opposite directions to (a) feed the generator with water and (b) to bring up to the earth's surface the produced steam for distribution.

Title: Calling station for emergency telephone - allows high gains without acoustic feedback by driving two loudspeakers in phase opposition
Inventor: SLAWIK MARTIN
IPC: H04M9/08
Filed: 1978-06-19
Abstract: The voice system has the incoming voice signals passing to two loudspeakers - one on each side of the microphone. The latter is located midway between the two loudspeakers. The two loudspeakers are connected in series in phase opposition. The advantage lies in being able to use high transmit and receive gains without producing acoustic feedback. The phase opposition prevents sound from the loudspeakers being picked up by the microphone.

Patent DE-2915223-A1 (DE)
Inventor: JAUNIN JEAN-PIERRE
IPC: G04G5/04
Filed: 1979-04-14
Abstract: To permit rapid setting of a countdown device such as a timer employing a digital display and a plurality of up/down counters 6, 22, 24, one for each digit, a single control switch 1 is provided which may be in the form of a push-button and the signal obtained therefrom acts on each counter until a predetermined count is reached and then on the succeeding counter. Thereby digital data may be rapidly introduced, precision of the set count (interval) diminishing however as its magnitude (duration) increases, as shown at the foot of Fig. 1. The by-pass circuitry is inactive during countdown so that the counters then operate in the normal way. <IMAGE>

Title: Primary aluminium alkyl prodn. from internal olefin - by reaction with aluminium hydride in presence of transition metal cpd. and aluminium alkoxide
Inventor: HAENSSLE PETER DR
IPC: C07F5/06
Filed: 1979-06-26
Abstract: Prodn. of primary Al alkyls (I) is carried out by reacting straight- and/or branched-chain internal mono-olefins (II) with cpds.

Title: Weft-bow correction roller with variable surface curvature - has surface of flexible laths controlled by adjustable spreader arms
Inventor: SCHIFFERS THEO
IPC: D06C3/06
Filed: 1979-09-18
Abstract: A roller for the correction of weft bow in a fabric has a surface composed of a series of regularly-spaced flexible laths, the ends of which are attached by hinges to a pair of circular end plates. In the middle of each lath is attached an articulated linkage connecting it to a pair of sliding bushes on the longitudinal shaft of the roller. The roller can be given a convex or concave surface of varying curvature by drawing apart, or pressing together the bushes: by moving both bushes in the same direction a sinusoidal surface is created which can rectify a double-bowed weft. The roller can be rapidly adjusted to deal with all types of bow, and eliminates the need for a series of rollers and time- consuming procedures for their exchange.

Title: Steel prodn. in converter - with introduction of carbon and oxygen below melt level to avoid foaming
Inventor: CHITIL MANFRED DR ING
IPC: C21C5/48
Filed: 1979-11-22
Abstract: Prodn. of steel from primary material in the form of scrap, sponge iron or other metallic, iron-bearing substances, comprises introducing into a converter having tuyenes in its melting zone, a column of the material in solid form and melting and superheating by burning fuel with oxygen flowing in counter current. Specifically, the charge is introduced into the converter in the side wall zone where the burners are placed above the tuyenes, so that the material is melted by the burners, when a liquid melt is formed, finely divided carbon and oxygen are injected separately into the melt via the tuyenes beneath the liquid surface. Formation of an uncontrollable foam is avoided and the need to add crude liquid cast iron is obviated.

Title: Thin shielding for epithermal neutrons - using layers of elements with nuclei of overlapping absorption resonance peaks
Inventor: SUSZKIN ANATOL
IPC: G21F1/00
Filed: 1980-02-25
Abstract: A thin shielding for epithermal neutrons in the energy range from 1-25 eV consists of a mixt. of selected chemical elements. Their atomic nuclei have high neutron absorption resonances which are chosen so that the overlap of the resonance spots of their absorption curves in the 1-25 eV energy range guarantees without any interruption a low enough transmission for neutrons. This shield for epithermal neutrons reduces both the space and the weight required for adequate protection.
