Title: Modular system for spectacles
Inventor: ERNST HANS-HELLMUT ING GRAD
IPC: G02C13/00
Filed: 1981-02-10
Abstract: The invention relates to a modular system for spectacles. Optical lenses and/or tinted lenses in a spectacle frame are used to correct eye defects or to provide protection for the eyes against an excessively high light intensity. In order to permit the spectacle wearers more flexibility with respect to concepts of fashion or to the type of spectacle desired at any instant, this modular system as provided by the invention for spectacles was conceived. It is distinguished in that it is possible due to ease of interchange to use a plurality of spectacle frames (2) differing in shape and colour for the benefit of one pair of spectacle lenses (1). <IMAGE>
Patent DE-3106486-A1 (DE)
IPC: E02D29/02
Filed: 1981-02-21
Abstract: Structural components for constructing a retaining wall, a noise barrier or similar structure are made up of a pair of horizontally extending generally parallel runner elements and connecting elements joining the runner elements together. The downwardly facing lower surface of each runner element has a concave curvature. The concave curvature is made up of a stepped surface which is higher at the outer side of the runner elements than at the inner side. Lines normal to the individual stepped surfaces intersect below the concave surface at a point. The structure components can be stacked one on the other to form a wall backfilled with earth or other material. Sound waves striking against the stepped surfaces are reflected into the slopes of the backfilled material between the individual components.

Patent DE-3214252-A1 (DE)
Title: Method and device for identifying the position of a workpiece surface or the like
Inventor: WILDER JOSEPH
IPC: G01B11/02
Filed: 1982-04-17
Abstract: The invention relates to a method and a device for identifying the position of a workpiece surface relative to a reference by means of contactless measurement. A beam is used to produce on the workpiece surface an illuminating spot which moves relative to the reference in the measuring direction along the workpiece surface with the motion of this surface. A field scanning detector determines without physically touching the workpiece the illumination in a multiplicity of small regions of the workpiece surface and generates corresponding signals. These signals are converted into a test signal which is a function of the difference in the total illumination between relatively large regions of the workpiece surface. A reference signal is generated and stored for two known positions of a workpiece surface. The test signal and the reference signal are combined with one another in order to generate a measurement signal which specifies the position of the workpiece surface relative to the reference.

Title: Process for producing a building material mix for floor screed and building material mix produced thereby
Inventor: GLASS KURT
IPC: C04B28/02
Filed: 1982-07-22
Abstract: A building material mix according to the invention for a floor screed both for the construction of dwellings and for industrial floors contains sand as the basic constituent and a binder as well as water. To enhance its sliding ability, a small quantity of talc is added to this building material mix. In addition to talc, a melamine resin, in particular a modified melamine resin, can also be added as a flow agent. By means of these additives, good flowability and hence processability of the screed mortar can be achieved with, at the same time, a lower proportion of water. The reduced proportion of water has, furthermore, also the advantage that the specific strength of the screed is increased.

Patent DE-3229861-A1 (DE)
Title: Lubricating device for a cylinder of a reciprocating-piston internal combustion engine
Inventor: LONKAI GABOR DIPL ING
IPC: F01M1/08
Filed: 1982-08-11
Abstract: In a lubricating device for a cylinder of a reciprocating-piston internal combustion engine, lubricating oil is fed to the cylinder by a supply device via feed lines and introduced under pressure into at least one lubricating oil distributor groove, arranged in the inner wall of the cylinder, through nozzle bores. The nozzle bores extend approximately tangentially to the inner wall of the cylinder and their longitudinal axes extend in the direction of the section of the lubricating oil distributor groove which is to be supplied, and an oil quantity/air stroke/feed control device is provided. Inserted into each feed line is a buffer store continuously supplied with oil at a certain pressure and holding a certain quantity of oil. Each buffer store is bounded on the oil inflow and oil outflow side by in each case one non-return valve, of which the valve on the inflow side prevents oil from flowing back into the feed line from the buffer store and the valve on the outflow side, which is situated as close as possible in front of the nozzle bores, prevents the entry of combustion gases into the buffer store but allows flow in the opposite direction. Each buffer store is furthermore connected to a compressed air source, via a compressed air feed line into which a solenoid valve is inserted. Each solenoid valve is connected to a control device and, for driving out the oil quantity stored in a buffer store, can be moved in each case from the shut-off position into the open position in a cyclically controlled manner by the control device by means of control signals triggered as a function of the running of the engine.
Patent DE-3230572-A1 (DE)
Title: Fishing-rod roller
Inventor: SUGIMOTO TATSUO
IPC: A01K89/015
Filed: 1982-08-17
Abstract: The invention relates to a fishing-rod roller with a pair of side plates, a bobbin shaft which is carried at both ends by the side plates, a drive mechanism, and a bobbin fitted to the shaft. A pair of concentric rings consisting of ferromagnetic material are fitted to one of the side plates and form an annular gap opening towards the inner side of the side plate. A magnetic body is attached to one of these rings and forms a radial gap. An annular flange of conducting, non-magnetic material, which is either fitted to the bobbin or forms a part of the bobbin, extends into the gap in order to form an eddy current rotor. The magnetic body has a series of individual permanent magnets which extend along it. Each magnet has one pole associated with the gap and the eddy current rotor, while the opposite, other pole is located in the immediate vicinity of the magnetic ring. The permanent magnets alternate in their pole direction or polarity, so that narrowly bounded, small magnetic loss currents (leakage of the magnetic flux) arise.
