Title: Suitcase with double walled moulded shells - replaceable band hinge between top and bottom
Inventor: HOFBAUER FRANZ
IPC: A45C13/00
Filed: 1975-04-10
Abstract: A suitcase consists of two double walled shells (1, 2) hinged by a band hinge (3) fitted in rabbets (7) in each shell so that a broken shell or hinge can easily be replaced. Round the edge of the upper shell is a stepped fitting edge which corresponds with an opposing fitting edge on the lower shell so that the shells hold together without sliding when the case is closed. Each shell has a rabbet (7) along one side of the outer wall into which is fitted the hinge band, which can be made of any durable plastic material. The hinge band has each edge thickened to double thickness so that when the band is pushed into the rabbet the thickened edge of the band is held behind a shoulder inside the rabbet. In an alternative form the hinge band is held in the rabbet by means of screws countersunk into the top of the shell edge.

Title: Electronic device to evaluate an optimum - uses diode or other function generator to investigate physical relationships having nonlinear characteristics
Inventor: SCHAEFER ECKEHARD
IPC: G01N25/64
Filed: 1975-11-07
Abstract: The electronic circuit includes a function generator (2), typically for moisture content or other physical variable, in parallel with a triangular waveform generator (3) with outputs leading to a comparator (4). From the latter signals proceed to precision rectifiers (7, 8) which also process input from temperature function generators (5, 6). Top and bottom boundary zones of the family of characteristics may then be evaluated, and can also be represented as voltages or currents by a diode or another function generator within required limits of accuracy. The generator delivering the voltage of a specified waveform determines the percent contribution of the function generator to the output test value and of the test value to be determined. The final stage is an integrator (9).

Title: Decay heat removal from pebble-bed nuclear reactor - uses auxiliary heat exchangers with gas flow reversed to natural convection
Inventor: WEICHT ULRICH DIPL ING
IPC: G21C15/18
Filed: 1976-09-10
Abstract: A method of removing the shutdown heat (decay heat) from a nuclear power plant, where the reactor is of the pebble-bed type with downwards gas flow through the core and heat exchangers incorporated in the concrete pressure vessel each with its own supply and return duct and gas circulator, makes use of auxiliary heat exchangers also incorporated in the concrete pressure vessel. These auxiliary heat exchangers are each connected in parallel or bypass flow with a main heat exchanger i.e., a steam generator. Each auxiliary heat exchanger has a communicating passage with the upper part of the reactor core vault. This communicating passage is closed during normal operation but, when shutdown heat has to be removed, is opened; this results in gas circulation upwards through the core and downwards through the auxiliary heat exchangers by natural convection. Used for any reactor in which the core is composed of a series of spherical elements, i.e., a pebble bed reactor. No auxiliary blowers or main blowers are required to maintain the removal of shutdown heat and keep the core down to the necessary temperature level.
