Title: Electronic memory with continuous braille text input - using preliminary memory with small storage capacity with associated blanks for reduced delays
Inventor: RAUPACH RAINER ING GRAD
IPC: B41J3/32
Filed: 1979-04-23
Abstract: The method of continuously in putting braille text into an electronic memory enables the elimination of delays high hither to experience because of the organization of the data recording and output by lines and pages. The braille text is initially written into a preliminary memory of small storage capacity where it is corrected as necessary. Each character is followed by a blank. When the preliminary memory is full its contents are automatically transferred word for word into a line by line organized main memory. The transfer is performed so as to prevent word fragmentation. Storage locations remaining at the end of each main memory line are filled with blanks. When the main memory is full, its contents are transferred to a further memory for further use and the page counter incremented.

Title: Motor unit for stirred pressure vessel agitators - having split-tube motor operating under pressure to ensure minimum pressure difference on shaft seal
Inventor: KRAEMER ROLAND DR
IPC: B01J3/00
Filed: 1979-08-08
Abstract: Motor unit for agitator consists of a high pressure split tube motor which is maintained at a pressure close to that of the vessel being agitated. The motor shaft and the agitator shaft are co-axial although an orbital reducing gear unit can be used between them, giving a speed reduction of 10, 14 or 30. The motor is filled with oil which is recirculated through an external cooler and maintained at the vessel pressure. The agitator shaft has a mechanical ring seal but the pressure difference across it is low. The unit is for use on stirred pressure vessels such as high autoclaves operating up to 500 deg.C. The system gives leak free operation at high temp. and pressure and is therefore esp. useful on toxic gases and vapours and other environmentally damaging materials.

Title: Draw=off system for liquor from centrifuge - using flat plate with grooves cut in it leading to run=off passage to reduce friction in liquid layer
Inventor: HOVSTADIUS GUNNAR
IPC: B04B1/08
Filed: 1979-09-05
Abstract: Liquid is drawn off from a rotating housing using a stationary draw off device. The liquid layer rotates with the housing forming an annular layer. a circular plate is mounted at the end of the housing the edges of which protrude into the liquid layer. The plate has quadrant shaped grooves into which the liquid is pushed by the rotational motion. This motion causes the liquid to flow along a passage which is parallel to the surface of the plate and out of an outlet parallel to the axis. The area of stationary plate in contact with the liquid is reduced and this reduces the frictional drag on the liquid.

Title: Sheet asphalt prepn. plant - charges aggregate fractions from hot silo pockets directly or through superheater in mixers
Inventor: STEINHORST HELMUT
IPC: E01C19/05
Filed: 1980-05-14
Abstract: Asphalt cement is prepared by storing the dried aggregates in separate compartments for each size range in a hot silo at a temp. of 160-200 deg.C. They are passed in metered batches through a superheater for raising the temp. to 220-380 deg.C and into the mixer. A bituminous binder, filler and any other required admixtures are added at this stage. This facilitates the conversion from asphaltic concrete with voids which needs compacting, to sheet asphalt which is free from voids, and saves time. It reduces the heat losses and the wear to a min.

Title: Measuring distance between float magnet and reference object - uses magnetic elevation track with coils embedded in core
Inventor: BREZINA WALTER
IPC: G01B7/02
Filed: 1980-07-04
Abstract: The arrangement for measuring the distance between a front magnet and a reference object with an electrically conducting surface is applicable to magnetic elevation tracks where the object is the support or guide rail. The arrangement can be placed in a magnetic core without significantly altering the effective air gap between the floating magnet and reference object.
