Title: Solar-powered boiler - has counterweights on baseplate so that it follows sun's movement,driven by fluid heated in cylinders
Inventor: EFUNE MICHAIL
IPC: F24S50/20
Filed: 1992-03-16
Abstract: A solar-powered boiler has a baseplate and a flat container for a zigzag pipe matrix, with a glass disk covering the sky-facing surface. The baseplate is supported underneath by a universal joint. At right angles to each other on the baseplate are two fluid-filled control cylinders whose piston rods carry a counterweight at each end. Near each cylinder, there is a pivoted lens holder, the neutral position of the lens being above the piston. The holders carry counterweights below the cylinder level and are connected to the piston counterweights by strings under tension. Solar radiation heats up the cylinder fluids via the lenses and the counterweights move the baseplate so that the boiler "follows" the sun. ADVANTAGE Achieves maximum utilisation of solar power through whole of day .

Title: FRP mouldings are bonded together to produce hollow articles - by wet=on=wet process using basically two dished parts which are vacuum preformed and then bonded together round rims by blow=up pressing.
Inventor: ZIMMERMANN JOCHEN
IPC: B29C51/10
Filed: 1992-11-04
Abstract: An FRP moulding consists of at least two cured dished members bonded together to form a tube and/or container; they are bonded on one or both rims or on the peripheral rim of one, pressed and joined with a cured overlap.

Patent DE-4238760-A1 (DE)
Title: Gear relaxation on stoppage - using counter control on reverse motion through belt drives to block relaxation or allow only controlled drift
Inventor: WAGNER HORST
IPC: B21C1/12
Filed: 1992-11-10
Abstract: To relax gearings on a machine stoppage within motor-driven and speed controlled gearing sections with belt drives, to drive rollers, the reverse rotation of the gearing section (4) acts on an actual value transmitter through the drive motor (6) with a speed control (10). In the absence of a nominal value, for the stoppage of the drive motor (6), at the start of the reverse rotation the negative direction of the actual value is changed to a positive direction for a positive value to set the speed control (10) so that the drive motor (6) is operated by the power unit in the original direction, so that it does not relax or only relaxes very slowly through a controlled drift. USE/ADVANTAGE - The method is for gearings with belt drives in machines with rollers to carry materials such as wires, films or paper which are sensitive to reverse rotation on a stoppage. The system prevents damage or shearing of the material on a stoppage, by taking up the torque and controlling any tendency to reverse.

Abstract: The method is performed without adding material which must be subsequential removed. The air gap is formed by a gate produced separately from the production of the FET base structure. A chemically sensitive surface can be optionally added to the gate which is applied to the base structure as a hybrid with an air gap height resulting from the height difference between the channel (6) and field (3) isolators. USE/ADVANTAGE - For producing SGFET with freely accessible space between gate electrode and channel isolator, e.g. for use in ion concentration analysers. High purity and low surface roughness can be achieved.

Title: Method for isolating and using guanylate cyclase-activating peptide I (GAP-I)
Inventor: FORSSMANN WOLF-GEORG PROF DR M
IPC: C07K14/47
Filed: 1993-03-26
Abstract: The invention relates to a peptide from human blood, GAP-I (guanylate cyclase-activating peptide), whose structure has been elucidated for the purpose of diagnostic, medical and commercial use as pharmaceutical. The isolation of this peptide GAP-I proves the existence of GAP-I. Deletion of certain amino acids from GAP-I reduces its biological activity. The GAP-I circulating in the blood is identical to the synthetic reference substance synthetic GAP-I but not to other peptides or its fragments. The molecular form of GAP-I has been proved by mass spectrometry. Differences in biological activity and differences in the spatial peptide structure of GAP-I compared with other GAP-I fragments prove that this GAP-I fragment represents the preferred natural peptide of the family of a peptide group which should be used for the treatment of numerous diseases associated with disorders of electrolyte transport into the cells. Furthermore, GAP-I (guanylate cyclase-activating peptide) can be used in one form or as natural crude extract for commercial purposes in research into new cell functions.

Title: Process for producing a multilayered conduit
Inventor: ZIEMEK GERHARD DR ING
IPC: B23K26/08
Filed: 1993-07-16
Abstract: A description is given of a process for producing a multilayered conduit, in which an inner tube of plastic is extruded, a longitudinally running-in metal band is formed around the inner tube to give a slit tube of a larger diameter than the inner tube in such a way that a gap remains between the inner tube and the slit tube in the region of the longitudinal slit, that the slit tube is welded by means of a laser welding device, that the welded metal tube is reduced onto the inner tube and an outer tube of plastic is extruded onto the welded metal tube. In this operation, the metal tube is adhesively bonded both to the inner tube and to the outer tube. The inner tube is surrounded by a metal band coated on both sides with a copolymer, and the adhesive bonding of the welded metal tube to the inner tube and the outer tube takes place via the copolymer layers by the extrusion heat of the outer tube.
