Abstract: 1376735 Fire-operated doors and windows TELEFLEX Ltd 18 July 1972 [23 July 1971] 34794/71 Heading A5A [Also in Divisions F2 and G1] A temperature sensitive actuator 16 for automaticaly operating a door or window installation 11 in the event of a fire comprises two rotary members 24, 25 (Fig. 3) separated by an energy storage spring 28 and an epicyclic year train, the rotary members 24, 25 and spring 28 being assembled to be rotatable conjointly except in the event of a fire when the rotary members 24, 25 are caused to rotate relative to one another by the action of the spring 28. As shown, the actuator 16 is inserted in a drive cable 10, 17 to a window installation 11 from a manually operable window opening and closing mechanism 12 in such a way as to provide a direct drive between the mechanism 12 and installation 11 except in the event of a fire when the actuator 16 automatically causes the window to close. The cable lengths 10, 17 which each comprise a relatively movable core and casing are connected respectively to an input wheel 24 and output wheel 25 of the actuator 16, the input wheel 24 being integral with a gear ring 27 which meshes with planet gears 31 carried by the output wheel 25. A spiral spring 28 which is fixed to the wheel 24 at its outer end is attached at its inner end to a spindle 29 which supports a sun wheel 30 meshing with the gears 31. The spindle is so connected by fusible plugs 34 to a tube 33 carrying the output wheel 25 that under normal temperature conditions the wheels 24, 25 are rotatable conjointly and maintain the spring in an energy stored condition. When, however, the plugs 34 fuse upon being subjected to an elevated temperature either directly by the action of a fire or by a heater 36 operatively connected to a smoke detector, the spring 28 releases its stored energy to cause the wheel 25 to rotate relative to the input wheel 24 and thereby close the windows 11.

Title: Shaping tyre rough to toroidal form - with differential motion between ends of bellows and beadings permitting bellows to slide inside rough
Inventor: MENELL HANS
IPC: B29D30/36
Filed: 1972-09-07
Abstract: A method of making a tyre rough by curving a cylindrical carcass to a toroidal shape fitting inside the treated band utilises an inflatable cylindrical bellows or tube; its ends are clamped in discs which are moved axially towards each other by an amt. exceeding the approach of the beadings, so that the bellows, axially longer than the width of the carcass, can slide into the carcass. After the curved shape has been reached, the beadings are brought still further together, while the bellows slide still further relative to the rough, permitting the beadings to rotate about their cores to form a torus.

Title: Digital display of data given in alphanumeric symbols - with fail-safe features, avoids false figures being exhibited
Inventor: LOGEMANN WALTER
IPC: B61L25/08
Filed: 1973-06-28
Abstract: The displaying of figures by illuminating various combinations of segments to form the desired number can lead to false numbers being exhibited if some segments fail to light up due to electrical faults. Where it is essential that false numerical information not be displayed due to electrical faults such as in railway signals and in weighing machines then the use of an eight or nine segment unit is required which utilizes the diagonal in both the upper and lower boxes to form figures. If any segment fails to light up, a meaningless combination of segments remains. This is recommended to replace bulky expensive numerical projection systems.
Patent DE-2333429-A1 (DE)
Title: Thyristor with four zones of alternating type conductivity - has steep concentration gradient of doping material in anode zone
Inventor: SCHLANGENOTTO HEINRICH DR RER
IPC: H01L29/00
Filed: 1973-06-30
Abstract: The thyristor has a conduction zone on the anode side operating as an emitter which normally has a flat concentration gradient of doping element. In this case the concentration gradient becomes very steep near the surface bordering the next inner zone. hence the doping in this conduction zone on the anode side is homogeneous with an abrupt fall at the junction. The thickness of this conduction zone is made smaller than in the conventional structure i.e. about five times the diffusion length of the minority carriers in the zone. This amounts to between five and twenty microns.
