Title: Telecommunication scrambler - permutates transmission wavebands and sequence, pseudo random number sequence makes unauthorised unscrambling very difficult
Inventor: RIEGER HEINZ DIPL-ING
IPC: H04K1/00
Filed: 1973-08-06
Abstract: A telecommunication information scrambling and corresponding unscrambling network is presented, in which both wavebands and information sequence are scrambled. The time scrambling system consists of an analogue to digital converter which feeds two shifting registers of information, so that one register information is transmitted, after scrambling, while the other is being filled. A pseudo random number generator chooses the order of elements of the buffer to supply the transmission information. The speed of transmission is doubled to accommodate the system. The waveband scrambler has a number of mixers to which the information is applied, and suitable bandpass filters. The mixing frequencies are fixed but are applied to the mixers according to a pseudo random output. In both cases the sequencing information is transmitted as part of the message.

Title: Lumps of dough depositing conveyor - retracted by chain drive in intermittent steps by inductive and capacitive proximity switches
Inventor: SCHNEE WALTER
IPC: A21C9/08
Filed: 1974-11-02
Abstract: Lumps of dough, carried along by an endless conveyor, are deposited in dough raising tins on a table under the conveyor by a chain drive which moves the return pulleys of the endless conveyor in carriages in intermittent steps. The chain drive moves the discharge pulley carriage against the direction of the endless conveyor until an inductive proximity switch stops it. When an approaching lump of dough is being deposited, a capacitive proximity switch initiates the next step motion. This requires no trailing cables which would have to be a screened type of low mechanical strength. No sensitive switchgear is exposed to mechanical stressed which would lead to premature breakdown. The device is simple and saves operating expenses.
