Title: Apparatus for demonstrating gravitational attraction of mass - comprises torsion balance with its gravitational masses heated in centre
Inventor: SCHNEIDER JOSEF
IPC: G09B23/10
Filed: 1974-02-18
Abstract: In order to demonstrate the attraction of mass or of the field of gravity it has hitherto been necessary to use comparatively heavy masses which effect a gravitational pull on the smaller masses of a torsion balance. The alternate appratus for demonstrating gravitational attraction has a device for heating the centrs of the masses exerting the gravitational force. For technical reasons, measuring masses in the central area and the large masses may have other than a globular shape e.g. they may be cylindrical. Pref. heating is effected by electrical elements. Movement of electrons may be caused by the heating.

Title: Centrifugal compressor for gases and vapours - has highly elastic thin blades of steel or plastic
Inventor: MUGELE KURT WILLY DIPL ING
IPC: F04D23/00
Filed: 1974-02-07
Abstract: The compressor is of a centrifugal spiral type in which multiple acceleration produces a pressure ratio 10 to 15 times higher than can be achieved in a radial blower of similar dimensions. To reduce noise the product of the number of blades and the rotary speed is chosen to give the oscillation of the fluid at the inlet and discharge openings a frequency above the highest frequency discernible by the human ear. At low speeds this requires a large number of blades which is made possible by the use of very thin and highly elastic blades of steel or plastic which are either cast into slots in the hub or attached to the hub by adhesives.

Title: AC circuit for parallel switching - switches in second generator to reduce loading of first when generators in phase
Inventor: GULDENAAR NAPOLEON
IPC: H02J3/42
Filed: 1975-01-22
Abstract: The switching circuit switches a second a.c. generator in parallel with a first a.c. generator when the load becomes two great for the latter alone. To determine the point at which the second generator should be switched in, the time between the point at which the two a.c. voltages last had the same phase and the point at which the switch-in must occur is measured, i.e. the time equivalent of the beat frequency is measured. The constant switch-in time is then subtracted from this measured time to give the point at which switch-in must occur if the generators are to have the same phase.

Title: Programmable time control for logic circuits - has counter dividing elementary clock signals and coupled to ROM
Inventor: CALCAGNO PIERO
IPC: G06F1/04
Filed: 1975-05-30
Abstract: The programmable time control, for logic circuits, simultaneously generates elementary clock signals (7) of arbitrary complexity. The bit configuration is stored and read out according to a given programmed sequence. The read-out is addressed by a signal (3) derived from a clock signal. A counter frequency divides the clock signal and produces periodic signals with progressively increasing period. A read only memory stores the various configurations of signal bits and redundance bits. A correction circuit (CP) uses the redundance bits to perform a test check on the elementary clock signals. A synchronisation circuit (RU, LT) ensures the sync. parallel emission of the elementary clock signals at given time intervals.

Title: Plastic staircase or verandah balustrade hand rail fixture - is made of integral soft foam and polyurethane with adhesive worked in for unheated fitting
Inventor: HERZHAUSER HANS JOSEF
IPC: E04F11/18
Filed: 1975-07-23
Abstract: The handrail is for staircase or verandah balustrades, or similar. It is made of plastic, but not of PVC, which normally needs to be heated before or during installation, to provide the flexibility needed for drawing over the balustrade, and for following curves. Here polyurethane with integral soft foaming is used, permitting installation without heating, by virtue of its elasticity. The adhesion between the structural handrail and the chord of the balustrade is provided by an adhesive, inseparably worked in during the foaming process. This has not set hard at this stage, and permits any amount of corrective action necessary during mounting, following removal of a protective polyethylene foil (4). There is no welding at the joints.
