Patent DE-4024280-A1 (DE)
Title: Flexible for use when tanker is damaged barrier - is lowered into sea to form enclosure for oil or other cargo between ship sides and barrier if hull damage causes cargo spillage
Inventor: GERKE GERWIN DR
IPC: E02B15/06
Filed: 1990-07-31
Abstract: The barrier, for carriage by oil tankers or other liq. cargo carriers, is intended to enclose cargo spilled from damage to the ship. When the barrier is lowered into the sea, its top is above the surface of the water, while its lower part is drawn downwards by weights to form the enclosure between the barrier and the ships' sides. The barrier is foldable and flexible, and is tension-resistant, impermeable and transportable. It is stowed along the top of the ships' sides, and if oil or other liq. cargo (5) escapes from the ships' tanks the barrier is lowered into the water to form, around the damaged hull (1), a second "hull" of adequate depth and distance from the ships' sides, that enclosues the leaking liq. USE/ADVANTAGE - The barrier is primarily for use when a tanker is badly damaged, in particular by contact with an underwater object, while the ship maintains for some time enough buoyancy for the barrier to be used. The retained oil (or other liquid cargo) is later removed by other means, but even when the spread of the oil is reduced, and delayed rather than prevented, the use of the barrier is justified.

Title: Aid for laying flagstones or tiles -  is shaped as cross with fifth arm at right angles to plane of cross
Inventor: VENDEL KARL-HEINZ
IPC: E04F21/00
Filed: 1990-08-27
Abstract: The aid for laying flagstones or tiles with uniform spacing and correct alignment, consists of a cross made of plastics (1). The cross has four arms which lie in a common plane and are spaced at 90 deg to each other. A fifth arm is attached to the centre of the cross and extends at right angles to the plane of the cross. The cross is inserted at the junction of four tiles or flagstones with the fifth arm projecting upwards. The fifth arm then serves as a handle to facilitate removal of the cross. The idea can be adapted for positioning stone blocks when building a wall. USE/ADVANTAGE - Correct positioning of flagstones and tiles.

Title: Detecting angles produced when flat sheet is bent
Inventor: SARTORIO FRANCO
IPC: B21D5/02
Filed: 1990-11-14

Patent DE-4114820-A1 (DE)
Inventor: DIMTER REINHARD
IPC: B27G11/00
Filed: 1991-05-07
Abstract: All finger jointing presses and finger jointing milling, gluing and pressing installations on the market are limited in their output because the pieces of timber pushed in one after the other have to cover lengthwise too long a transporting path until the individual positions, readying for longitudinal transport, for threading in and for pressing or for working, are reached. The subsequent setting time of the glue is too great, since there must be intermediate stops prior to selling or working, corresponding to at least one day's production.  An increase in output and reduced setting time is required. This is remedied by an invention where the boards or pieces of timber are widthwise laterally ahead of the pressing or processing position and the glue and hardener is specified in the heated state. The installations may advantageously also be heatable. <IMAGE>
Patent DE-4116683-A1 (DE)
Title: Wind sifter for separate removal of coarse and fine materials - has preliminary jet pipe and high-speed gas jet for initial dispersal of material
Inventor: NIED ROLAND DR ING
IPC: B07B7/083
Filed: 1991-05-22
Abstract: The jet pipe (25) which forms the material inlet (9) for the sifter opens tangentially into the winder sifter housing and contains a coaxial air inlet nozzle (26) through which the high speed gas jet is introduced into the pipe. The material is supplied into the jet pipe through a conveyor (28). The material mixture is thereby dispersed before entering the actual wind sifter (5) so that any pipe particles clinging together which could be treated as coarse particles are now dispersed. USE/ADVANTAGE - A high degree of separation resulting in less dust or fine materials in the end yield of coarse particles.
Patent DE-4121334-A1 (DE)
Inventor: STROEDTER WILHELM
IPC: B66C23/00
Filed: 1991-06-25
Abstract: The proposal is for a lifting device for manually moving a load on a pivoting jib in which the inherent weight and load moments are reliably compensated by a counterweight and a pressure-operated fluid cylinder with the aid of an electronic-pneumatic control and regulating system for the momentarily necessary working pressure in the cylinder. The lifting device can be balanced sensitively and accurately with reference value transmitters with the aid of an electronic-pneumatic valve and an electronic processor coupled to a zero-point regulator and a slope controller as well as an electronic balance. The system is completed to form an ideal whole by the addition of various safety circuits to detect the actual load and movement situation.
