Patent DE-2407247-A1 (DE)
Title: Ejector for granular material - has small seating for ejector disc and narrow and continuous contact surface
Inventor: MATZKE RUDOLF
IPC: B65G31/04
Filed: 1974-02-15
Abstract: The support flange and the ejector disc with its ejector paths fit neatly together. The ejector disc is made of highly wear-resistant material. The seating surfaces are kept narrow and restricted in number. The contact surface is continuous but narrow so that it may be ground easily and rapidly, so that no granular material may penetrate inside the support flange cavity. The safety disc is fixed by means of a cap and screw, inserted from inside to give a smooth surface in the middle of the ejector. The axle is hollow to take the screw.

Title: Gear wheel made from roller chain - has spring loaded clamp ring for set torque transmission
Inventor: STEGHERR RUDOLF DIPL ING
IPC: F16H55/10
Filed: 1974-03-27
Abstract: To produce internal or external gears, roller chains or tooth belts can be used. A flanged circular plate provides the gear body. The chain is clamped against the plate flange by a clamp ring, spring washers and screws. This enables the chain to slip if a set torque is exceeded. Tooth belts can be bonded to internal or external locations to achieve the same function. The chain could instead be positioned by projections on the plate periphery extending between adjacent rollers or by side plates receiving the roller cross pin to provide a rigid coupling. Chains positioned side by side are held by extensions of the roller pins and spacers between.
Patent DE-2416784-A1 (DE)
Title: Line monitoring system for unearthed networks detects shorts - and breaks by monitoring volts across phase lines and earth and monitoring lines
IPC: H02H3/17
Filed: 1974-04-06
Abstract: The line monitoring system, for unearthed networks, has a first monitor monitoring the voltage difference across the two power-carrying lines, and a second monitor monitoring the voltage across the earth line and the monitoring line. Each monitor has its own operational amplifier acting as a trigger comparator and controlling warning lights etc. The advantage of the monitoring system lies in its being able to indicate failures in the earth and monitoring lines separately from the condition of the power lines, and therefore does not automatically break the power circuit on earth line failure.

Title: Uniform continuous aeration of sewage in pits - of non-circular shape or with eccentric mounting of aerator
Inventor: EISELE FRANZ
IPC: B01F7/02
Filed: 1974-11-22
Abstract: The parent specification describes a device for aeration of sewage in pits comprising a propeller driven by a submersible motor mounted ona carrier pipe and having an air inlet near the propeller. According to the present specification, the motor, which revolves about a vertical axis to face different parts of the pit, is so controlled that its position in relation to the wall of the pit which it faces determines the length of time for which it faces that wall. Thus, for the purposes of enrichment with O2 of the sewage, the greater the distance to the pit wall, the longer the residence time of the motor when facing that wall.

Title: Continuous heat sterilising process for fluid, etc. containers - has pressure compensating, gas layer preventing zonal heat transfer
Inventor: NEISS OSKAR ING GRAD
IPC: A23L3/02
Filed: 1975-12-31
Abstract: A process for the heat sterilisation of fluids or solid materials such as infused solns., biological solns., preserves for foodstuffs, in sealed containers, is carried out continuously in one passage. In the heating zone the containers pass through compressed, satd. steam, and they are transferred from this zone through an atmos. of non-condensing gas, such as hot air, which being specifically lighter, separates the steam in the hot zone from the cooling agent in the cool zone, and serves to compensate the pressure difference between the two. The process is carried out in a continuous run through a plant which prevents mixing of the sterilising and cooling media with each other or the compensating gas. No sluice is required inside installation.
