Patent DE-2732807-A1 (DE)
Inventor: NAGATA SEIICHI
IPC: C30B23/04
Filed: 1977-07-20
Abstract: Three-dimensional structures having a suitable geometrical configuration are directly formed on one major surface of a substrate so that an epitaxial molecular beam may be incident on preselected regions, and the angles of incidence of epitaxial molecular beams are varied. As a result the arrival rates of molecular beams are varied from one region to another on the substrate so that a three-dimensional epitaxial layer in which the physical properties are different from one region of a submicron across to another may be grown.

Title: Oscillating segment drive esp. for printing wheels - has segment driven by crank and connecting link to set type wheel axle
Inventor: NEUMANN HELMUT
IPC: B41J7/34
Filed: 1977-09-12
Abstract: Adding and like office machine has printing wheels driven by a toothed segment engaging a pinion on the wheel axis. The segment is driven by a crank connected to the segment through a connecting link. One rotation of the crank therefore causes a full oscillation of the segment. The crank and the segment are supported in bearings in a side panel of the machine. The segment may remain in mesh with the pinion throughout the operating cycle.

Title: Rapid glow plug heating for diesel engine - supplying overcurrent to plug until glow temp. is reached and then pulsing current
Inventor: SCHMIDT ALBERT
IPC: F02P19/02
Filed: 1977-09-24
Abstract: For rapid heating of the glow igniters of diesel engines the igniters are fed with excess current until they reach their glow temperature, after which they are supplied with current intermittently. The time taken by the igniters to reach their glow temperature is shortened, and they are kept at this temperature until the engine has started. Indicating lamps light intermittently when the glow temperature has been reached. If the engine temperature is initially equal to or higher than the required starting temperature the lamps do not light up, indicating that the engine is ready for starting.

Patent DE-2747731-A1 (DE)
Title: Inductive position indicator for control rod - has bridging element with specific hole pattern moving along induction coils
Inventor: NIKOLAEV VLADIMIR PETROVITSCH
IPC: G01D5/22
Filed: 1977-10-25
Abstract: A position indicator for linearly moving objects comprises inductance coils arranged coaxially along the path of a moving bridging element of magnetic material and generally tubular or annular shape sliding outside these elements. Thus, as the magnetic bridging element moves along, it bridges coils and causes signals to be produced indicating the position of the moving element. The bridging element comprises groups of holes along its axis, each group being arranged in a ring; one of the inductance coils has >=2 pole pairs spaced axially apart, such that the distance (L) between the outermost pairs of poles is defined by L=n(a+b)-1/2(a+3b), (where a is width of hole of bridging element along its axis of movement; b is distance between successive gps. of holes; n is a whole number >2). Used for determining the position of linearly movable components in inaccessible, typically gastight vessels; more specifically for monitoring the position and movements of control rods. The new arrangement enables the position of the rod at any location along its path to be determined very accurately with relatively simple equipment.

Patent DE-2827460-A1 (DE)
Title: Reducing metal blank to multiple parallel bars - by stepwise progression through oscillating contoured rolls
Inventor: VYDRIN VLADIMIR NIKOLAEVITSCH
IPC: B21B1/42
Filed: 1978-06-22
Abstract: The rolls progressively change the cross-section of the blank to one comprising multiple parallel bars linked by webs, and at the end of the transitional zone the bars are displaced transversely to the webs whereby they are separated. The initial cross-sectional area is no less than the sum of those of the product bars, and the initial width not greater than the total width of the closed passed of the mill rolls. The stepwise advancement of the workpiece alternates with the bar separation step. There are also claims to mill rolls for the process, each roll having several grooves each of varying cross-section. The roll contour is defined by a mathematical formula involving rolling parameters. Useful for bars produced in continuous casting plant. Roll wear and energy requirements are reduced.
Patent DE-2828115-A1 (DE)
Title: Toxic refuse dump effluent - purified by precipitation and decanting in segmented circuit tank
IPC: C02F1/52
Filed: 1978-06-27
Abstract: Toxic effluent which has seeped through refuse dump heaps is treated by a pptn. reaction followed by decanting. Fe (III) salts and activated carbon are admixed as precipitant and stirring continues for an adequate reaction time. The decanted fluid can be discharged to the drainage system or to a biological sludge treatment. This results in optimum cleaning efficiency, e.g. from over 2000 mg. KMnO4 per litre to under 200 mg. The aerobic method is beneficial to a subsequent biological treatment.

Title: Protective glove of fluid-tight material with extension cuff - has outwards facing groove forming seal with outer ring
Inventor: ROLOFF PETER-MICHAEL
IPC: A41D19/00
Filed: 1978-07-22
Abstract: A cylindrical ring of elastic material is positioned close to the edge, on the inside face of the extension cuff for a protective glove of fluid tight material. The edge of the extension cuff is turned over inwards, and the then outer surface of the ring has an annular groove. When the cuff of the glove is drawn over the extension cuff, both cuffs are pulled by an elastic toroidal ring into the annular grooves. The arrangement avoids the necessity for cuffs having a large amt. of material forming overlaps, and facilitates the drawing off and on of the extension cuffs and the gloves.
Patent DE-2833106-A1 (DE)
Title: Oil remover for ship's bilge water - uses heated tank under low pressure to separate water before discharging it
Inventor: KNUDT WALTER
IPC: B63J99/00
Filed: 1978-07-28
Abstract: The oil and water mixture from the bilges is collected in a settling tank which is heated by heat exchanger coils utilising waste heat from the engine, espec. a Diesel engine. The tank is partially evacuated to aid evaporation of the water content so that the oil remains for subsequent collection and removal. The steam formed is condensed by seawater fed cooling coils and is vented into the sea. The system provides a pollution free treatment of bilge water for vessels in protected waters. The amt. of liq. in the system is automatically controlled via. overflow an liq. level sensors.

Title: Molten core catch vat - for pressurised water reactor made or uranium oxide with cooled bottom
Inventor: BAGGE ERICH PROF DR
IPC: G21C9/016
Filed: 1979-04-12
Abstract: There is a risk of a core melting in pressurised water reactors if the prim. cooling circuit or its pumps fail. Fuel element can metal mixt. may drop on the tank and fuse it.

Bottom of the vat is designed with a honeycomb structure to which an independent and additional cooling system can be applied for the dissipation of the heat. Material of the vat has pref. an admixture of neutron absorbers. This safeguards the personnel against the risk of a molten core.

Patent DE-2933034-A1 (DE)
Title: Membranes on alternate cloth-covered filters in series - with filters covered by cloth only
IPC: B01D25/12
Filed: 1979-08-16
Abstract: The aligned axial passages for the flow of media in the tightly compressed edges of membrane filter plates have branches extending obliquely to filter chambers bounded by adjacent plates. These membrane-covered plates alternate with plates covered by cloth only, and have a support plate with a thickened edges on whose two faces is a frame which grips the membrane and has filtrate exit channels. Each filter plate has axial passages at all four corners, with one of these for delivering slurry connected to the filter cake cavity by troughs in the support plate. Diagonally opposite the slurry passage is a passage supplying pressurised media for compressing the filter cake. The frame is connected to the support plate by plastic plugs. The sealing difficulties involved in known membrane presses are overcome, so high pressures, e.g. 15 bar, can be used for filtering, compressing or washing. The presses are easier to mfr. than the type with adhesively-bonded or vulcanised membranes, and the generally diagonal flow of the washing water is beneficial.
