Title: Non-clogging ventilation inlay for shoe soles - has non-return valve to force out damp air away from incoming air
Inventor: DEHM GEBHARD
IPC: A43B17/08
Filed: 1978-11-02
Abstract: The resilient inlay is completely impermeable to air on the underneath. It is only partly impermeable on the upper side and has a cavity (4, 5) extending over its entire length with air inlet openings in the heel area and air outlet openings (16) over the remaining area. At least one non-return valve (6) is mounted between the two parts of the cavity on the inlay (1) to open in the direction of the air outlet openings (16) so that when treading on the heel the air inlet openings are closed and the air in the cavity into which these inlets open is forced through the non-return valve to the air outlets. As the foot rolls over the ball area the air at the front cannot flow back because of the non-return valve so that it all escapes via the outlet openings. In this way all damp air is removed and cannot return to mix with the pumped in fresh air.

Title: Detection system sensing people on moving staircase - uses light source, parallel reflecting strips and photodetector, preventing restart after emergency stop
IPC: G01V8/14
Filed: 1979-03-24
Abstract: The detection system has two parallel reflecting strips located one each side of the stair treads just above their surface. A light source at, e.g. the bottom of the staircase, directs light at an angle onto one reflecting strip. This light is reflected alternately from one strip to the other, zig-zagging across the staircase, finally being received by a photodetector located at the top of the staircase. Any person on the staircase interrupts the light beam and causes the photodetector's output to change. The system prevents the staircase being started after an emergency stop. The staircase cannot be restarted if a person is on it and therefore likely to be in danger.

Title: Safety vent for vehicle fuel tank - has lateral buffer chambers with air blockage when vehicle overturned
Inventor: SCHEURENBRAND DIETER
IPC: B60K15/035
Filed: 1980-04-19
Abstract: The safety vent prevents fuel from escaping if the vehicle is turned over. A venting chamber (13) under the top of the tank is linked to the tank by two venting lines (9,10) and to the atmosphere by a third venting line. The two internal venting lines are taken in loops to each side of the tank and looped around widened buffer chambers (4,3) which connect each vent line to the tank. The loops are widened to form the buffer chambers and to break up any column of fuel when the vehicle is tilted to prevent a siphoning effect. This safety feature can be applied to most vehicle fuel tanks and provides a simple and safe protection without interfering with normal venting.
