Title: Fitting elastomer seal onto flanged rim - by feeding length of channel section strip into robotic device which bends it, presses it onto rim and moves round periphery of rim
Inventor: GOEDDERZ DIETER
IPC: B25B27/00
Filed: 1989-12-15
Abstract: A channel-section elastic strip is fixed on to a flange or similar by a procedure where the strip is fed on the flange across its length; the start of the strip is forced to follow a curved path with the part of the strip immediately after its start aligning its channel with but separated from the flange; the strip is then moved in so that it engages the flange; finally the strip length is moved further and pressed round the flange. ADVANTAGE - The method and the equipment used are better than earlier systems and they provide an effective seamless joint between the start and end of the applied strip (e.g.  a door edge seal).

Title: Shelling crab without damaging flesh - by longitudinal cutting to depth controlled by crab thickness scanner
Inventor: FRIEDHOFF WILFRIED
IPC: A22C29/00
Filed: 1990-01-17
Abstract: Crabs (10) stored in similar positions, esp. tail-first in a magazine (12) are delivered one by one to a rotary cutter (13) whose blade (20) is moved vertically through a distance determined by a scanner (27) monitoring the crab thickness, and thus ensuring that only the shell itself is cut through, without affecting the flesh (229.

Title: Valve for oil flow control for burner - opens only when pressure insufficiently high to maintain steady flow
Inventor: NEUMANN FRANK ING GRAD
IPC: F23D11/38
Filed: 1990-09-13
Abstract: The flow of oil to the atomiser nozzle of an oil fired burner is controlled by a valve which has a chamber (3) with an outlet (6) which can be closed by the small dia. end (15) of the piston (10).

Title: Short electrical filter for cleaning a particle-laden gas flow - has octagonal pipe outlet superimposed on square pipe inlet
Inventor: DAUM KARL-HEINZ
IPC: B03C3/06
Filed: 1990-12-27
Abstract: In an electrical filter for cleaning a particle-laden gas flow, gas pipes function as deposite electrodes with an axially-arranged spray electrode in each pipe, with pipes formed by sheet metal panels arranged in parallel and sepd. by flat spacers to give each pipe a regular polygonal cross-section inlet and an octagonal outlet. The novelty is that the pipe inlet is square and that the outlet is octagonal and superimposed upon the square inlet. A suitable arrangement incorporates a pipe (1) assembly with square inlets (E) and an octagonal outlet (A) with four opposite sides in line with the inlet (E). The pipe faces (4,11,12) are of roughly equal length. The pipe sides and corner-members are of equal length. The metal panels and spray electrodes are longer than are the corner members in the direction of gas flow, so the electro-filter formed by the tubes is effectively preceded by a plate electro filter. There is a gradual transition in the pipe cross-section between the inlet and the outlet. The transition begins after one third of the distance from the inlet. USE/ADVANTAGE - The arrangement provides for an efficient filter of short length requiring less materials and providing cost savings.

Title: Extinguishing oil well fires - using large, sand-filled flexible bag which is dropped onto the fire to smother the flames
Inventor: KABADAYI SELAHITTIN
IPC: E21B35/00
Filed: 1991-05-02
Abstract: Extinguishing oil well or similar erupting fires, comprises dowsing of the fire by a large volume of sand or earth, delivered suddenly from a large bag lifted over the flame source. The bag is made from flexible, fire and tear proof material. The size of the bag is sufficiently large to carry a volume of extinguishing material which will envelope the fire. The bag is attached to a ring with eye bolts, which allow a lifting block to be attached. The fill substance, sand, etc., will become molten from the heat of the fire, and form a solid, air tight block over the when cooled again. A further development for larger fire areas, has a firm flattened dome container, with a screwed lid. The lid may be removed once the fire has cooled and allows the well to be brought back into service. ADVANTAGE - Uses locally available dowsing materials. More predictable than explosive means of de-oxygenating a fire. Overcomes the difficulty of uneven ground allowing fresh air into the area, when using bell housing extinguishers.
Patent DE-4116601-A1 (DE)
Title: Flood-water seal for e.g. doors or windows - consists of fabric-reinforced soft PVC sheet fitted with edge chambers which are placed into guides and inflated when flood danger arises
Inventor: KARWATH ARNO DIPL ING
IPC: E06B9/00
Filed: 1991-05-22
Abstract: A seal for openings, e.g. doors and windows in particular in buildings to prevent ingress of floods uses fabric-reinforced unplasticised PVC sheeting which is only activated when risk of flooding arises. The sheet is set into guides arranged round the opening and is made to act as seal by pumping up chambers which are in the sheeting by the guides. Pref. the guides (2) are box-section hollow components which are placed inside the opening (3) in a building and which have a longitudinal slot in the inner side. The seal against flood-water is normally kept rolled up but when the danger of flood arises it is unrolled and inserted through the slot.  Air holders (4) are located in the sheeting where it it inserted into the guides (2). When the sheeting has been unrolled these holders (4) are inflated. The action can be made automatic by having a moisture sensor beneath the opening and causing this to energise the inflation process. When installed on the ground floor of a building the product can replace rolling shutters. ADVANTAGE - The invention prevents any damage from occurring by flood entry through doors and windows (as conventional seals are only effective against air draughts).
