Patent DE-2720026-A1 (DE)
Title: Automatic loader for pressing film-faced boards - in which the stack is deposited horizontally on platen by lifting system and controls
Inventor: BRUESSEL RICHARD ING GRAD
IPC: B27N3/22
Filed: 1977-05-04
Abstract: A stack consisting of synthetic resin/carrier or films on top and below a core is loaded into a hot press using a longitudinal loader and dropping its whole area simultaneously on to the heated platen by withdrawing the loader. The stack is made up with the leading edge projecting beyond the edge of the loader. When the press is open a withdrawing carriage with clamp enters the press. The clamp grips the leading edge of the loader while withdrawing and lifting the previous press load. The leader and carriage are connected and moved into/out of the press and stopped. The loader returns, the load being positioned over the bottom platen. The stack is released from the loader, the clamp opens and moves towards the carriage, and the whole area of the stack is deposited simultaneously on to the platen. Quick press loading is obtd. with no localised pre-cure or slippage of cauls or stack materials.
Patent DE-2729421-A1 (DE)
Title: Polyamide prodn. from adipic acid and hexa:methylene:di:amine - using aq. monomeric nylon salt soln. made using recycle condensate from the autoclave and evapn. stages
Inventor: SIEKMANN ARTHUR ADOLF DR
IPC: C08G69/28
Filed: 1977-06-29
Abstract: Water is added during the salt-forming stage from the diamine and acid, so that the monomeric salt is obtd. as an aq. soln. The aq. soln., together with the usual additives, is concd,in an evapn. stage and the concd. soln. is then subjected to polycondensation under heat and pressure. All the vapours recovered during the concn. and polycondensation stages are condensed and the whole of the condensate from teh polycondensation is mixed with part fo the condensate from the pre-evapn. stage. The combined condensate is then used in the salt-forming stage inplace of fresh water. Process allows recycling of vapours resulting from polycondensation and concn. stages, which contain a number of environmental pollutants, which can no longer legally be released into the atmosphere or drains. These substances are difficult and expensive to remove from theffluent. The process overcomes this problem by recycling these pollutants to the reaction mixt., which has no deleterious effect on the polyamide prod.

Title: Fuel economy system for vehicle - automatically stops or restarts engine by accelerator pedal dependent switches
Inventor: KORF OTTO
IPC: F02N11/06
Filed: 1977-08-11
Abstract: The ignition current flow from the ignition switch lock to the ignition primary coil is interrupted by a switch actuated by the accelerator pedal. The starter motor relay is actuated by the accelerator so that when the pedal is depressed, the starter is activated and the ignition circuit is closed. The starter is deactivated as soon as the engine fires. There is a considerable redn. in exhaust gas emission in heavy traffic conditions. The system is applicable for both diesel and petrol engines. The system could be used with a freewheel system in the transmission to facilitate freewheeling with the engine stopped.

Title: Automatic threshold control for data readers - adjusts sensitivity of optical detector according to background level
Inventor: KUGLER ROLAND
IPC: G06K7/10
Filed: 1977-08-12
Abstract: The scanning system comprises a light source focussed onto a moving band (2) which carries a series of marks (1). The signals from a detector (7) are amplified and pass to an amplitude detector (10) and are also rectified (11). The rectified signal can be stored in alternative polarities in capacitors (12)(17) by means of a switching circuit (14, 15) which is controlled from a timing generator (28) and multivibrator (25). A reference timing generator (29) drives a multivibrator (30) which, in turn, operates further switches on the input and output of the second storage element (20, 21). The output signal is amplified to provide a control signal for the discriminator. Between successive markings or groups of markings, the noise voltage from the scanner is measured to provide a control signal to adjust the sensitivity of the detector.

Title: Operational technique for pressurised water cooled nuclear reactor - prevents damage to fuel elements by regulating output density
Inventor: ALEITE WERNER DIPL ING
IPC: G21C7/00
Filed: 1977-11-28
Abstract: A pressurised water reactor having a core formed by fuel rods and fitted with monitors for determining the distribution of the output over the core, has an arrangement receiving signals from the monitors, for restricting the reactor output, if threshold values for the output density are exceeded. The reactor is operated so that the threshold value of the permissible operational density of the fuel rods is approximated to the actual reactor output density when output is falling, with a time constant of days, and when output is rising, with a speed of alteration of about 5%/h to within a distance of 50 %/cm. To prevent mechanical damage to the fuel element envelopes by changes of loading due to pellet-cladding-interaction. the technique allows the envelope to flow in the elastic zone under the action of the expanding fuel tablets, without shearing.

Title: Roughened surface for handles of tools or utensils - consists of regular rows of pyramid shaped projections
Inventor: SCHMIDT HORST
IPC: A61H7/00
Filed: 1978-03-13
Abstract: The method of increasing the surface roughness of the handle of a tool or utensil consists of producing rows of pyramid shaped projections (10) separated by narrow lanes of a flat surface (20). This type of surface increases the tactile sense of the user's finger tips and is particularly useful for the manually clumsy person. The height of the tip of the projection (10) above the flat surface (20) should be between 0.66 mm and 2.5 mm for the most effective grip. The pyramids (10) may have square diamond or lozenge shaped bases.

Title: Laminated annular seal - comprises corrugated steel core ring with sharp-crest corrugations and cuttable incompressible plastics or soft metal washers on either side
Inventor: TUECKMANTEL HANS-JOACHIM DIPL
IPC: F16J15/12
Filed: 1978-06-29
Abstract: Composite ring seal comprises a corrugated metal ring coated on both sides with a sealant which is compressed and forced into the "valleys" of the corrugations under the action of sealing forces. The coatings are flat, annular discs (of washer-type) when in non-deformed condition, whose thickness is chosen so that corrugation "valleys" are filled out under compression and the discs themselves are cut through by the "crests" of the corrugations when compressive forces are applied. To facilitate this, the corrugated metal ring is provided with some corrugations having cutting crests. The ring discs are made of incompressible material which is, however, adapted to be cut (as indicated above), suitable PTFE, graphite, Al, Pb, Au, Ag. The metal ring is made of (superior alloy) steel.

Title: Two=phase synchronous motor - has permanent magnet rotor and non-uniform distance between stator poles
Inventor: DROEGE CARSTEN ING GRAD
IPC: H02K21/16
Filed: 1978-09-28
Abstract: The two phase synchronous motor has one pair of poles, or teeth, more on the stator than there are permanent magnet poles on the rotor. To improve performance characteristics, in particular the standstill position holding, with the supply off, the stator teeth are not uniformly spaced. The non-uniformity is achieved by having one stator punching and by cropping the edge of some of the teeth on at least some of the punchings so that the effective tip spacing at the air gap is changed. The whole and cropped laminations can then be assembed as required.

Patent DE-2904705-A1 (DE)
Inventor: NUSSBAUM HELMUT DIPL PHYS
IPC: C03B37/022
Filed: 1979-02-08
Abstract: Hollow glass fibres laminated materials suffer, still nowadays, from the fault of containing water and other substances. The sealing processes used up to flow still show defects which are eliminated by the invention. The hollow glass fibre receives sealing walls during the spinning operation which takes place with a protection gas comprised of an aerosol wherein the material of the tight wall is in suspension. For this purpose, small hollow glass balls are used, of which the diameter corresponds to that of the fibres. The aerosol is directed by a cooled nozzle of the hollow fibre inner diameter, so that the current speed corresponds approximately to the spinning speed (about 1 to 1.5 m/s).
