Patent DE-2023337-A1 (DE)
Title: Nuclear reactor - with chain type control rods stowed in curved tubes - within the pressure vessel
IPC: G21C7/14
Filed: 1970-05-13
Abstract: The control rods are stowed in curved tubes within the periphery of a space at the bottom of the pressure vessel whence they are expelled by actuators into straight guide tubes running upwards through the core and into which, conversely, they can be withdrawn from the core using the thrust/pull forces between the links. The storage and guide tubes and the actuators are all within the space through which the coolant flows to the core. As well as height reduction, the technique simplifies the construction of the pressure vessel.
Patent DE-2052134-A1 (DE)
Title: Thermoplastic netting made from heat shrunk - slit film
IPC: B32B27/00
Filed: 1970-10-23
Abstract: Oriented thermoplastic film is cut with a pattern of slits and subsequently relaxed, while gripped to prevent overall contraction so that those slits which are oblique or especially transverse to the principal axis of orientation are opened up to form a series of (hexagonal) pores due to contraction of the intervening material. Where the resulting flat foraminous films are required for lamination with others, e.g. for construction of filter elements, the films are subsequently passed over rolls coated with adhesive resins at a viscosity which results in gobs of adhesive being retained in the pores in the passing net.

Title: Sugar cane extraction - using multistage pressing with counter flow o extraction liquid
IPC: C13B10/04
Filed: 1971-07-12
Abstract: A process for extraction of soluble substances from fibrous material by pressing and macerating, suitable for extraction of sugar from cane, consists of preparing an uncompacted layer of the material; pressing it between two surfaces, one o which is perforated, to remove he extracted liquid through the openings; relieving the pressure and wetting the material rapidly as it re-expands so that the voids of the layer become filled; conveying the layer to a succeeding station, where this liquid is extracted and recycled in contra-flow to the advancing direction of the layer, to be used as the wetting liquid in an earlier station. This process is repeated a number of times between successive pairs of pressing rollers, the extraction liquid moving in contraflow to the fibres layer.

Title: Reverse flow block - operated by shaft through screw press for duroplastic injection
Inventor: DEERBERG ROLF
IPC: B29C45/52
Filed: 1972-03-30
Abstract: At the end of the screw press, the thread flank extends in a line parallel to the axis of the screw, before turning round to define a passage. This passage is exposed when the lock on its internal shaft is turned into the open position, rotation of the shaft bringing the lock round to block this passage on the injection phase.

Title: A:D converter circuit with reduced channel capacity - detects nonperiodicity in voiced component and converts corresponding voice signals into min. number of binary signals
Inventor: FELLBAUM KLAUS DIPL ING
IPC: H03M1/00
Filed: 1972-04-15
Abstract: The A/D converter converts voice signals into a minimum number of binary signals and thereby reduces channel capacity. Periodicity in the voiced component is detected where this periodicity is absent, voiceless components are assumed to be present and a given sequence is used instead of the period. Each signal sample is used to produce a binary signal. Signal parameters are determined for each binary signal. The difference between these parameters for consecutive periods or sequences is determined, coded and released.

Title: Thin layer chromatography plates - using polymeric acrylate or methacrylate esters of polyhydric alcohols as binders
Inventor: SHIOZAWA AKIYASU
IPC: G01N30/93

Abstract: The TLC plates consist of a flexible inert carrier, coated with an adsorbent layer contg. as binder a homo-co-or graft polymer of a monoacrylate or mono-methacrylate ester of a polyhydric aliphatic alcohol. The binder gives a good bond to the carrier and between the adsorbent particles, and is resistant to conc. H2SO4 used for revealing colourless substances. When water is used as developing solvent, the adsorbent layer is not loosened from the plate. Sepn. and concn. of individual substances during use is better than with plates using known polymer binders.
Patent DE-2302965-A1 (DE)
Title: Regulating level in extruder reservoirs - by controlling the rate of operation of the extruder
Inventor: GOELDNER HORST DIPL-ING
IPC: B29C48/92
Filed: 1973-01-22
Abstract: In a device for regulating the level of a discontinuously charged storage vessel of an extruder to a predetermined mean level by controlling the rate of operation of the extruder, a corrosion (DELTA n) to a basic rate of operation of the extruder is calculated from the difference (hs-hi) between the predetermined mean level (hs) and the measured level (hi) between charging operations and this correction is applied continuously or when beginning a new charging operation to alter the rate of operation (ns) of the extruder, the rate then being kept constant between charging operations. Advantageously the extruder is operated at a rate which is directly proportional to the measured level in the storage vessel, so that the predetermined mean level can be arranged to give a known rate of operation of the extruder.

Title: Pipe or ball mill lining - has adjacent buckle plates forming dish with axially facing bulge on side(s)
Inventor: SCHNEIDER GERT
IPC: B02C17/22
Filed: 1973-09-06
Abstract: Lining for pipe or ball mills consists of axially and peripherally adjacent buckle plates, forming a dish. Each plate has a bulge on at least one side facing axially, and the wall thickness of the plates increased in the axial direction, and preferably reaching the height of a bulge. The dish is assembled from four plates; the pitch of the plates arranged axially of the mill and forming a dish is different. Milling fineness and yield are increased. The former is produced by the varying diameter of the chamber of the pipe mill from input to output. The latter is produced by the increasing thickness of the walls of the plates creating a fan shaped broadening of the floor of the basin to the outlet of the mill. Milling surface is thus increased.
