Title: Intruder resistant roller shutter securing mechanism - has L=sectioned bars with retainer plates providing locking in any position
Inventor: GLAS FRANZ
IPC: E06B9/80
Filed: 1977-08-04
Abstract: Rail-type security bars press the blind sheet firmly against the outside shanks of laterally mounted shutter guide rails. The security rail is L-shaped in cross section (5). For pressing it agains the shutter sheet (3), outwards from the interior of the building, it has swivelling pressure members (6), fastened to the L-shaped rail by a retainer plate (62), while a further retainer plate (61) fastens them to a window frame stock (2). The security rails may be extruded from aluminium or tough plastics, with both shanks of the same height. This enables the shutter to be secured in any position, whether closed or partially open for ventilation.

Title: Device for irradiation of body cavities - includes a series of radioactive and neutral balls locked in tube by larger ball and recycled automatically
Inventor: HOOFT ERIC VAN T
IPC: G21F5/02
Filed: 1977-08-12
Abstract: Device for irradiating an internal cavity of the body comprises a distributor for putting together a row of balls including radioactive and neutral balls; >=1 applicator tube to be inserted into the cavity; and a pneumatic feeder with which a row of balls can be loaded into an applicator tube and discharged from it. The applicator tube has an enlarge section leading down over a shoulder to a section of reduced dia. the length of which conforms to that of a row of balls, and the row of balls is locaked in by a ball of larger dia. which cannot pass the shoulder and rests against it making a seal. A sorting, storing and distributing arrangement has magazines for radioactive and for neutral balls connected to the distributor by valves, and a sorter allocating the returned balls to the magazines. Each applicator has an intermediate magazine in which the row of balls is set up and to which they are returned after use. The channel connecting the intermediate magazine to the sorter is so small in dia. that the locking ball cannot pass, but remains in the intermediate magazine. The device ensures that the radioactive and the neutral balls are maintained in position correctly for as long as is necessary. Leakages and the use of large amts. of air are eliminated.

Title: Fuel system for IC engine - has mixture of compressed air and fuel under pressure injected into cylinder to reduce exhaust pollutants
Inventor: MIXICH KASIMIR
IPC: F02M69/08
Filed: 1978-11-10
Abstract: The engine has a piston reciprocating in a cylinder. There is a sparking plug in the cylinder head and an exhaust valve which opens on the upstroke of the piston. An injector in the cylinder head introduces a mixture of air and fuel into the cylinder. The air is previously compressed and the fuel is delivered under pressure by a pump.

Filed: 1979-05-11
Abstract: The dishwasher includes several support frames (13) which have upwardly aligned spikes (19) to hold the articles (20) to be washed whereupon the supports can be pushed into the wash chamber (3) one above the other. Each support frame (13) has a downwardly projecting connecting pipe (22) and an upwardly projecting connector (50, 60). The system ensures that when each support frame is pushed into the wash chamber (3) and is located in the operative position each connecting pipe (22) can be brought into engagement with the connector of the support frame below or with the fixedly installed connector (10) so that a complete pipe system is produced ensuring the water reaches the water outlet nozzles (21) provided on the holder spikes (19). At least the connectors (50, 60) of the uppermost support frame (13) in the wash chamber (3) can be closed to ensure the water circuit is complete. It is preferable however if all the connectors have an automatically closing seal wherein the flow cross-section must be open when the support frame above is in the operative position.
