Title: Up-and-over garage door with spring protection
Inventor: DOERING ERICH
IPC: E05F5/00
Filed: 1981-03-31
Abstract: A garage door, with a lifting linkage having lateral lever arms, to the force arm of which are connected expanded tension springs which are fastened to the frame of the door and which are relaxed during the opening of the door and can keep the door leaf in the approximately horizontal opening position, possesses, over each tension spring, a tubular protective casing which encloses the latter completely and the length of which is greater than that of the tension spring in the fully expanded state. To make mounting easier in the case of thicker springs or double springs which are inserted one into the other, and to increase the effectiveness of the spring protection, provision is made for the protective casing to be designed, parallel to its longitudinal axis, in two parts consisting of a lower part receiving the tension spring and of a cover placed thereon. A snap-on rebate is preferably provided for retention. To increase safety in the event of a spring break, one embodiment provides for each tension spring to be retained by a closed steel retaining shackle which extends axis-parallel inside and outside the tension spring and which, in the expanded state, encloses it without constraint. <IMAGE>

Title: Process for producing concrete pipes provided with an interior lining of plastic or the like and device for carrying out the process
Inventor: STEENWEG HEINZ
IPC: B28B21/94
Filed: 1981-04-22
Abstract: In a process and a device for producing concrete pipes provided with an interior lining of plastic or the like, it is provided first for a concrete pipe to be produced and hardened in a manner known per se and then for the plastic for forming the interior lining to be applied in flowable form, from the interior of the concrete pipe, onto the inside thereof by means of a preparation and application cylinder, smoothed off to form a thin layer by means of a following drawing head and cured to form the interior lining. The external diameter of the preparation and application cylinder and of the drawing head is less than the internal diameter of the concrete pipe so that they are axially movable relative thereto, and the external diameter of the drawing head additionally forms, with the inside of the concrete pipe, an annular gap determining the thickness of the interior lining. The production of such concrete pipes is considerably simplified in this manner. In particular, the work effort associated with the production of the interior lining is reduced, avoiding undesirable dependency on the concrete pre-casting plant.

Title: Process for recovery of gaseous oxygen under elevated pressure
Inventor: SKOLAUDE WERNER DIPL ING
IPC: F25J3/04
Filed: 1982-05-03
Abstract: In a process for recovery of gaseous oxygen under elevated pressure by means of low temperature rectification of air in a pressure stage (7) and a low pressure stage (15), the air is compressed, cleaned, at least partially cooled in a first heat exchange device (6) in heat exchange with separation product and conducted into the pressure stage.

Title: Device for economically controlling main line trains
Inventor: TEICH MANFRED
IPC: B61L3/00
Filed: 1982-05-24
Abstract: In a device for economically controlling main line trains, the travel and brake control device (AB) present on each train is fed on the one hand control signals upstream of devices (ST) which ensure safety and subordinate control characteristics (SK1) which are interrogated in a location-dependent manner from a memory (SP2) and serve to optimise travel in terms of energy. For journeys outside the normal operation, control characteristics (SK2) are determined separately from case to case for travel which is optimised in terms of energy and are activated in place of the aforesaid control characteristics (SK1). The advantage of the device lies inter alia in the fact that in the case of new situations arising during operation due to deviations from the timetable it can be tested, in a departure from the first control characteristics (SK1) which are permanently prescribed for normal operation, whether or not it is appropriate to adopt a speed profile with respect to the required energy and an achievable gain in travel time, and accordingly to feed the corresponding second control characteristics (SK2) to the travel and brake control (AB) of the train. <IMAGE>
