Title: Flexible roller shutter cover for swimming baths - is formed of hollow, extruded PVC sections linked along long edges and having ends sealed by rib removal and pressing faces together
Inventor: FISCHER HELMUT DIPL ING
IPC: E04H4/08
Filed: 1991-03-12
Abstract: A roller-shutter type cover consists of extruded hollow PVC sections which have flexible joints along the long edges and are divided into separate chambers by ribs. The section ends are sealed to form watertight chambers allowing the cover to float on water. End sealing is achieved by tapering the inner ribs (3,4) and side pieces (5,6) and pressing upper and lower surfaces of the profile .together. The faces are then welded or bonded together to form the water-tight lip which can be bent out of the main plane as desired. USE/ADVANTAGE - The connected sections can be linked along the long edges to form a floating, flexible cover for swimming baths.

Title: Cyclic automated assembly machine - uses single drive motor to operate all functions via worm drive and cams
Inventor: ECCARD HERBERT
IPC: B23P21/00
Filed: 1991-04-09

Title: Automatic umbrella locking mechanism -  releases separate spring-loaded slides for folding and unfolding
Inventor: LIU FU-TIAN
IPC: A45B25/14
Filed: 1991-06-11
Abstract: The umbrella comprises a stem with handle (1) and crown (4) at opposite ends. A slide (5) travelling along the stem acts on struts (3) between it and the crown, these being unfolded and folded by extension (10) and return (15) springs. A locking slide (13) travelling on the stem is coupled to the first slide by a cord (12) reeved round a guide (11) at the top end of the stem, and a locking mechanism (9,14) at the handle engages separately with the two slides, holding both in the ready position when the extension spring is under load with the struts folded. To unfold, it merely releases the first slide. It releases the locking slide so that the return spring can fold the struts. USE/ADVANTAGE - Locking device prevents inadvertent openings of umbrella and risk of injury.

Title: Roll crusher for granular foodstuff - esp. for crushing grain to flakes
Inventor: DESAGA HANS DR MED HABIL
IPC: B02C4/08
Filed: 1991-06-22
Abstract: A processing device, esp. for crushing granular foodstuff (e.g. grain) to flakes, has two or more parallel rolls journalled at one or both ends, the novelty being that the rolls (6,7) have rough cylinder surfaces with a finite spacing. Both rolls may have granular surfaces or one roll may have recesses of width similar to the length of the grain being processed, while the other roll has groups of at least two adjacent projections which, during rotation of the rolls, cooperate with the recesses to form a gap between each recess and each group of projections. USE/ADVANTAGE - The device is useful for prodn. of wholemeal flakes for domestic prodn. of bread, pasta, oatflakes, uncooked foods (e.g. muesli) and the like. It provides reliable entry of grain into the roll gap without uncrushed grain passage and without cuts in the grain husks.

Title: Vision improving appts., partic. for vehicles - has reception optic forming differential image signals from video signals of identical impingement sense.
Inventor: WEIDEL EDGAR DIPL PHYS
IPC: G01S17/88
Filed: 1991-09-09
Abstract: The appts. has an illuminating optic, radiating a light beam widened in one plane, and another narrow focussed beam perpendicular to the first one. It scans a preset spatial angle by swivelling towards the narrow focussed beam. A reception optic is arranged offset from the above plane w.r.t the illuminating optic.

Title: Pressure limiting pneumatic valve for commercial vehicle brakes - has spring biased piston with poppet valve and unloading valve element built into end sections
Inventor: GASSMANN HEINER
IPC: G05D16/10
Filed: 1992-05-16
Abstract: A pneumatic pressure limiting valve has a main poppet stage (17) that controls the flow from a supply (14) to a load (16). The poppet is formed in a cylindrical piston (4) that is subjected to a spring force on one side and pneumatic pressure on the other. A second valve stage (38) is formed at the end of the piston and has a section (12) that locates against a seal (40) set into the read. A small piston (31) provides a safety relief function. When the pressure limit is reached the main poppet closes. Unloading is provided by the small piston valve. ADVANTAGE - As soon as it leaves its normal position, the piston immediately changes over to the closing position of the first seat valve, the effective surface of the piston part additionally coming into operation. Undesired intermediate positions of the piston in the closing path are avoided. Upon return of the piston to the normal position, the safety valve is used without hindrance to change the effective surface of the piston part without exerting pressure. The piston is then ready for the next accelerated switching movement.
