Title: Bottle cap sorting machine - has rotating plate with control passages and supply conveyor and removal channel with outlet
Inventor: BAER KARL HEINZ
IPC: B65G47/14
Filed: 1977-12-06
Abstract: The machine to sort small parts the diameter of which varies between the main surfaces such as corks or screw closures for bottles, wing nuts etc. receives the unsorted parts from a feed conveyor. A horizontal, driven plate (14) below the conveyor has control passages (17) positioned in a circle along one edge area of the rotating plate which rotate largely in the same direction as the plate. The visible profile of the passages largely corresponds to the side profile of the small parts on the rotating plate. There is a ring shaped removal channel radially outside the control passages for those parts positioned correctly on their side and passing through the control passages. This has at least one outlet and at least one turn-over device for those small parts retained by the control passages which lie on the wrong side on the rotating plate.

Title: Speech coding with increased protection against unauthorised decoding - involves continued generation of random numbers until suitable coding number is generated or limit is reached
Inventor: ROHM PETER DIPL ING
IPC: H04K1/06
Filed: 1978-03-07
Abstract: Speech coding is controlled by random numbers from a random generator. Each random number is tested for its suitability before using it for codings that passages of straightforward speech do not occur. When an unsuitable random number appears, the random generator delivers new random numbers until a suitable number appears or the number of numbers delivered by the generator reaches an upper limit. When this happens the delivered random number is used irrespective of its suitability for coding.

Title: Multiple glazed unit - using adhesive cleats to secure panes in spaced relation
Inventor: MAZZONI RENATO JOSEPH
IPC: C03C27/12
Filed: 1979-11-21
Abstract: Spacer is mounted between panes to provide an air space there between using an adhesive cleat having a shear property >40 lbs/sq. inch (2.8 kg/sq. cm).
