Patent DE-2715197-A1 (DE)
Title: Seal between centrifugal pump stator and guide plate - is made by annular membrane taking up large movements
Inventor: DUSCHA OTTO
IPC: F04D29/42
Filed: 1977-04-05
Abstract: A multi-stage centrifugal pump has a series of impellers (I, II, III) with radial blades (3, 4, 5) attached to a shaft (2). Flow is guided between each pair of stages by stator blades (7, 8, 9) and a flow guide plate (6). The guide palte (6) is sealed to the stator casing (1) by a membrane (12). The membrane is an annular irng in the radial plane and presses against the guide plate at its inner circumference (14) on the high pressure side. At its outer circumference it abuts on an annular step (11) on the inside of the stator casing (1). This provides a better seal than can be achieved by O-rings for large pumps in which the gap between guide plate and stator can attain large dimensions.

Title: Removal of ammonia from effluent water - by treating in a column with milk of lime, removing ammonia with a hot gas stream and burning the lime sludge
Inventor: HAESE EGON
IPC: C01C1/10
Filed: 1977-05-18
Abstract: In parent patent ammonia is expelled from an ammonia-contg. soln., which has been treated with milk of lime in a stripping column and from which the ammonia has been driven out with a hot gas, steam or vapours. A bottom prod. is drawn off contg. lime sludge, calcium sulphate, unused hydroxide, calcium carbonate and other calcium compounds, and passed to a settling unit in which the sludge is separated from the liquid. A pumpable sludge is withdrawn from the settling unit and passed to a combustion chamber together with fuel gas and air, and burnt under reducing conditions at 600-1200 degrees C. The resulting combustion gases are led into an immersion vessel where the resulting calcium compounds are converted into Ca(OH)2 with an aq. liquor, and the resulting vapours are used for other purposes. Pref. in the addition, combustion is at 600-900 degrees C giving Ca sulphide which reacts with the aq. liquor to give calcium hydroxide and calcium hydrosulphide.

Title: HV three=phase power transformer short circuit protection appts. - uses current input circuit with input current transformers and measuring system for comparing transformer currents
Inventor: RIJANTO HENDRO DIPL ING
IPC: H02H7/045
Filed: 1977-08-09
Abstract: A short-circuit protection appts. is for primary-side and secondary-side main current-transformer groups whose output currents are compared in a protection relay. The current input circuit comprises input current transformers and measuring system for comparing the currents of the input current transformers. The appts. is designed to protect against short-circuits and to eliminate the need for any intermediate current-transformers. Thus, the current input circuit for the discrete rotary switching groups is arranged so that it forms predetermined relationships, for comparison in the measuring system, from the interlinked transformer currents and/or difference magnitudes from the discrete transformer-phase currents and the transformer sum-current.

Title: Large perforated clay brick - has slits in adjacent rows offset in heat flow direction to assist firing
Inventor: SCHWAEGLER HELMUT
IPC: E04B2/14
Filed: 1978-04-20
Abstract: The stone or block, in the form of a large-format building brick, has holes formed by stem pieces and slits. The stems in the heat flow direction are intermediate walling sections set parallel to each other, dividing the slits, which are in a line at axial right angles, into individual rows. The slits(7) in two adjacent rows (8) are mutually offset in the direction of heat flow(A), so that the dividing cross stem pieces (10) in the block(1) are interrupted at each intermediate walling section(6), crossing over into the walling sections in the area of the slits in the adjacent row. The cross stems of one row can be aligned in the centre of the slits of the next row. This arrangement prevents fissure formation during drying or firing.

Patent DE-2828263-A1 (DE)
Inventor: BAILEY JACK H
IPC: G11B20/12
Filed: 1978-06-28
Abstract: A video recording disk is adapted to be rotated at a uniform angular velocity and to have bit positions of substantially equal length along a track, and the longer outer tracks are given more storage positions than the shorter inner tracks. Variable numbers of frames are located on each track revolution, depending on the data capacity of the track. Frames are divided into data units that correspond to a few horizontal lines, and frames on the same track are interlaced so that the data units of each frame are distributed evenly around the track revolution. The associated record player has simplified data storage requirements, particularly for freeze frame display of the television picture and for playing disks that hold video information in a data compression format.
