Title: Image intensifier with photocathode transmitting layer - has sections linked via high resistance and voltage drop preventing screen overload
Inventor: LIEB ALBERT DIPL ING
IPC: H01J31/50
Filed: 1976-03-13
Abstract: Image intensifier has a photo-cathode layer and a cathode electrode on the inner surface of a light transmitting photo-cathode mount. One ring shaped section of the cathode is connected to the photocathode layer and the other ring shaped section is connected to the negative pole of a direct voltage source. The second electrode section (4) is connected to the first electrode section (3) interleaved with a ring shaped insulated section (5). The surface of the first electrode section has a smaller surface area than the second. Its electrical connection to the second section is via a high resistance (R2). The other end of the first ring shaped section is connected to the negative pole of the voltage source (10) via a high cathode resistance (R1). The intense optical radiation will cause a voltage drop necessary to prevent the energy falling on the light screen (8) from exceeding its loading capacity.

Title: Fire resistant sliding steel doorway - has screws as sole connection for rebated plate joints with insulating battens
Inventor: ERNSTING UWE ING GRAD
IPC: E06B5/16
Filed: 1977-07-09
Abstract: The large steel sliding fire-retarding door comprises one or more load bearing frames together with insulating panels covering this, themselves covered by sealing plates which are made from sheet metal plates folded together.

Title: Dimensionally stable and wear-resistant nozzle - for spraying liq. agricultural soil additives, is made of glass-fibre- or glass-bead-reinforced polybutylene terephthalate!
Inventor: GRAEF STEFFEN
IPC: B05B15/00
Filed: 1977-08-03
Abstract: Injection-mould spray nozzle for spraying e.g., manure, fertiliser, plant protectives, is made of polybutylene terephthalate. The polybutylene terephthalate contains a glass-fibre or glass-microsphere filler. The body of the nozzle has a moulded-on, annular sealing lip on that side nearest the bottom of the filler of the spraying unit. The filter is associated with the nozzle body and has also a sealing lip. The filler in the plastics matrix not only improves its mechanical strength and abrasion resistance but usefully reduces the coefft. of thermal expansion. The prod. is considerably less expensive than prior art brass or stainless steel nozzles yet more corrosion-resistant than the former and more accurate dimensionally than the latter which are difficult to machine and hence not amenable to mass prodn.

Title: Polygonal pin in door lock operating handle - has stop bolt moved into long hole in catch by outside tool
Inventor: JAEGER HORST
IPC: E05B3/02
Filed: 1978-02-15
Abstract: The polygonal, and esp. square, lock pin is for insertion in a matching hole in a lock and setting on a door handle. There is a vertically extending blind channel in one end, housing a catch, resiliently pressed downward, with a guide piece and a blocking piece. The latter snaps into a matching counter hole on a door handle. The catch(12) incorporates a continuous lengthways hole.
