Title: Anti drilling plate for walls of safe - has layer of rotable balls for absorbing energy of rotating drilling tool
Inventor: DANZER JOSEF-HELMUT
IPC: F41H5/04
Filed: 1975-06-10
Abstract: The hole-drilling prevention plate element is especially used for protecting safes against breaking in. The protecting system resists drilling with high quality tools by using relatively cheap materials in the safe wall. Safe walls are made of plates which have under their outside skin a layer of cheap steel alloy balls arranged so that these balls are able to rotate. These balls are embedded into plastics, pref. into a thermosetting plastics. In another version the balls are held in a plate with blind holes whose dia. is slightly larger than that of the balls. The blind holes are covered with a plate with blind holes. On drilling the tool meets the balls and these balls begin to rotate which absorbs the kinetic energy of the rotating tool so that the layers below are protected.

Title: Safety pressure regulator for sub atmospheric glove box - closes supply if pressure rises and vents discharge if it falls
Inventor: GUENTHER ELMAR
IPC: G21F7/04
Filed: 1975-07-09
Abstract: A safety device is used for adjusting and maintaining a predetermined slightly sub-atmos. press. in a closed space (e.g. a remote-handling glove box), which is supplied with inert gas from a pressurised source and is continuously, slowly evacuated by an extract fan (extract line 4). The extract line is fitted with a vent valve; if the inert gas supply fails and the extract fan continues to operate, this vent valve opens to permit entry of atmospheric air. The inert gas feed line (2) contains a cut-off valve (14); if the extract fan fails and the inert gas supply continues, this cut-off valve is closed. Used esp. for glove boxes for remote handling of contaminated or radioactive articles, e.g. pyrophoric carbide fuel, using an inert e.g. He-Ar atmosphere. The system reliably prevents (a) an excessive pressure drop leading to an inflow of air, with accompanying risk of fire, and (b) an excessive pressure rise, leading to an outflow of contaminated inert gas.

Title: Burner valve for bulb operated lighter - has hollow bulb piercing needle with radial gas inlet port
Inventor: MOHR WALTER ING GRAD
IPC: F23Q2/173
Filed: 1976-06-04
Abstract: The burner and valve assembly for a lighter using disposable bulbs, is improved in such a way that the needle penetrating the bulb closure is shaped to allow a repeated withdrawal and subsequent insertion of the bulb into the lighter without loss of fuel. The relevant part of the neddle is its tip, which is solid, while the upper part of the needle is hollow. The tip produces on the resilient bulb closure a point-like perforation and the radial gas inlet port connecting to the axial bore of the needle is located at a point, where it is safely within the gas area of the bulb. The elastic material of the bulb closure yields during the penetration of the needle and when the bulb is removed the hole closes again without loss of fuel. The bulb is sufficiently guided to allow piercing at the same point every time. In addition the rotational shape of the needle ensures that during the penetration it does not give way sideways.
