Patent DE-3931662-A1 (DE)
Inventor: MOLL PHILIPP
IPC: B65G47/68
Filed: 1989-09-22
Abstract: Process and device for aligning and joint processing of limp workpiece layers (4, 104). The workpiece layers (4, 104) to be processed jointly are brought together suspended from endless conveyors (1, 101). In a scanning and aligning station (10) located in the path of the two endless conveyors (1, 101), at least one workpiece layer is removed temporarily from the corresponding endless conveyor, aligned with the other workpiece layer and returned to the endless conveyor in the aligned position. The associated workpiece layers then leave the scanning and aligning station (10) together. The invention makes it easier to fasten clamps (16, 17; 116, 117) for the workpiece layers to the endless conveyors, where they are held by permanent magnets (14; 114) whose magnetic field is temporarily suppressed in the scanning and aligning station (10). Alignment is therefore carried out with minimal friction.

Title: Aerodynamic leading edge section - powers Darrieus vertical turbine or is used on aeroplane or land vehicle turbine or is used on aeroplane or land vehicle for speed
IPC: B64C3/14
Filed: 1990-03-21
Abstract: The use of the aerofoil in the region of the aerodynamic tip of the land vehicle, starkly reduces the resistance factor of the air, by the deflection of the air, to allow higher speeds, without the necessity of a slender profile. With the wind turbine it facilitates the use of a larger torque and self starting with high running r.p.m. The distance of the leading edge section (e.g. 11) can be altered so that, by altering the distance the flow relationships reach favourable values. A lateral movement of the leading edge section can create a braking effect, and the number of revolutions can increase. The carrier of the leading section or itself is spring mounted. USE/ADVANTAGE - Profile increased to give higher torque and leading section introduced to reduce friction of air.

Patent DE-4013871-A1 (DE)
Inventor: ROSA WALTER DIPL ING
IPC: C04B28/02
Filed: 1990-04-30
Abstract: In a process in which pulverulent fine cement, plasticiser, swelling agent, quartz powder and water are mixed to give a cement suspension, it is desirable that, in crevices, and in particular also in crevices of very much smaller width, the cement suspension gives crevice-grouting of more compact consistency, improved cohesive force and frictional bonding. This is achieved by first adding water-retaining polyethylene oxide of a molecular weight of at least 40,000 to the water, 0.040 - 0.090 parts by weight of polyethylene oxide being added per 100 parts by weight of fine cement, by providing the fine cement and the quartz powder in a grain size of < 40  mu m and adding only 1.5 - 3.2 parts by weight of quartz powder per 100 parts by weight of fine cement, and by adding the swelling agent only to the mixture of the cement suspension. This gives crevice-grouting of improved consistency even in the case of relatively fine crevices.

Title: Spray valve for nozzle bank in rolling mill stand -  is controlled by electromagnet bolt which when (de)activated forces ball to left or right for fluid flow or evacuation in chamber
Inventor: KRIEGER MATTHIAS
IPC: B21B45/02
Filed: 1990-09-26
Abstract: Device consists of an electro-magnetically (7) operated bolt (10) which normally is spring-biased (9) in a forward position which forces ball (17) towards the left, thereby blocking the passage of pressurised fluid from entry channel (23) to depressurising channel (24) and causing the fluid to flow via channel (25) to chamber (26) where it acts with spring (27) to force piston towards the left and close spray opening (31).  When the electromagnet is activated, the bolt is withdrawn towards the right, thereby releasing ball (17) which moves towards the right to block channel (23). The fluid in chamber (26) is evacuated via channels (25, 24) and the piston forced to the right against the spring pressure (27) by fluid entering (32) under pressure. This fluid is then released from spray opening (31). ADVANTAGE - Device has small dimensions and is easy to construct and dismount. Parts can easily be exchanged, thereby reducing costly down-time.

Title: Solar radiation collector unit, is small for convenience - is shaped to absorb radiation on small area, and has foam plastics plus thin metal heat exchanger
IPC: F24S23/70
Filed: 1990-12-11
Abstract: A solar heat collector consists of a number of small units which are disposed to take diffuse bundles of radiation. The product pref. uses foam styrene polymer in its structure. The prod. is made up of e.g. polyurethane foam, an inner aluminium heat exchanger and a covering window. The shape enables it to absorb max. solar radiation at noon as well as more from the sides during the afternoon. Optimal radiation intensity thus reaches the tubes inside after reflection from the sidewalls. These tubes are the heat exchanger. The design can be made to blend in with e.g. roofs in residential areas. ADVANTAGE - The size of prod. allows it to incorporate e.g. foam mouldings. The conventional thickness of internal parts allows them to be set obliquely and catch solar radiation over a wide area. The design allows a large irradiated area to act on a smaller absorbing area. The small size allows e.g. the window to be injection moulded with webs, and the heat exchanger to be cheap thin aluminium sheet (or copper) electrically welded and inflated to form e.g. worm flow ducts or simi
