Title: Oil filter for IC engines - with concentric inflow and outflow pipes which cannot run dry
Inventor: HOYER UWE ING GRAD
IPC: B01D35/14
Filed: 1979-05-17
Abstract: A filter for liqs., specially for lubricants of internal combustion engines, has a central inlet pipe for the oil which ascends to just below the lid. After passing radially inward through the filter element, a coaxial standpipe receives the clean oil at an inlet just below the top flange of the filter element; the outflow for the clean oil is also at the bottom. The filter thus can never run dry, even when the oil supply is interrupted, without requiring any non-return valve (which may fail if dirt collects on the valve seat).

Title: Automatic sorting of rectangular components - using code disc that generates pulse sequence with photoelectric sensing to allow orientation to be determined
Inventor: TRENKLER GERHARD PROF DR ING
IPC: G06K7/10
Filed: 1980-03-15
Abstract: An automatic sorting process for rectangular profiled components uses a code marking that is machine read and interpreted in order to decide the orientation. Each rectangular component has a bar code marking that consists of dark segments that are based on a common centre. The segments are of two widths: a wide segment indicating a '1' state and a narrow segment indicating a '0' state. An extra wide segment indicates a start of the code sequence and an outer ring provides initial identification. A photoelectric scanner locks onto the code disc and a pulse train is generated that is amplified and is passed to a processor module. The processor assesses the code marking to determine the initial position and so fix the orientation of the component.

Title: Thermoplastics screw caps moulded from sheet - on revolving pref. square drum with mould cores on each face passing through successive stations
Inventor: PETROV ZAFIR DIPL KFM
IPC: B29C51/22
Filed: 1980-03-20
Abstract: Appts. for making internally threaded thermoplastics caps for bottles etc. operates with a revolving drum, of polygonal, esp. square cross-section, having a number of core moulds, each corresponding to the internal form of a threaded cap, projecting outwards from its flat surfaces; a continuously moving thermoplastics sheet passes around this revolving drum so that the regions around each projecting core mould initially receive the basic shape of a cap. As the drum continues to revolve its sides pass through the successive moulding stations and the portions of sheet remaining on each core mould are subjected to the succeeding moulding operations required for their completion. Pref., the next moulding station cuts or punches out the sheet around each core mould; after that a knurled edge, an imprint etc. may be produced in further stations. Used for the prodn. of thermoplastics caps for bottles and similar articles. The appts. operates simply and efficiently in an economical manner. All the devices required for the various moulding operations are centered around the revolving, polygonal drum in a restricted space and in each working cycle of the machine the various tools execute different operations simultaneously.

Title: Rock drill tool joint - is shrunk sleeve joining rod end to shank end
Inventor: WEHRMANN KARLHEINZ ING GRAD
IPC: E21B17/02
Filed: 1980-03-22
Abstract: A tool joint between the shank end for a rock drill and an extension drill rod consists of a sleeve which has been shrunk both to the shank end and to the drill rod. The bore for the former is pref. smaller than that for the latter. Both face ends are kept in close contact with each other. This eliminates the power losses in the conventional threaded tool joints, transmits the impact energy better to the drill bit and has a longer service life. The steadier drilling also results in lesser wear to the drill chuck bushes.
Patent DE-3018528-A1 (DE)
Inventor: MEHNERT WALTER DIPL ING DR ING
IPC: G01P3/481
Filed: 1980-05-14
Abstract: The instantaneous angular velocity of a rotating shaft or the like is translated from the relative rotation of a mark carrier, having a scale of marks, and a sensing device. A series of signals are produced and processed in a calibrating run and thereafter in a series of operating runs. In the calibrating run, the time distance of the sensed signals between at least one pair of the marks is measured and from it a calibrating value is calculated corresponding to the absolute angular distance between the marks and thereafter stored. During the operation runs, the instantaneous time distance of the sensed signals between the marks is measured and the instantaneous velocity is obtained by comparing it with the stored calibrating value.

Title: Ring spinning-twisting process - uses ring round spindle without travellers
Inventor: MAIDEL HERMANN
IPC: D01H1/06
Filed: 1980-07-11
Abstract: The yarn runs from the outer surface of the ring, away from the centre point, and is then deflected to slide over and through the ring for winding. Pref. in operation the ring has an axial stroke movement, without rotation, but it can be given an intermittent rotation round its axis against the direction of spindle rotation, or the ring can rotate freely round its axis, being turned by the yarn. Pref. the yarn passes at least a times over the upper surface of a lower ring, coaxial with the ring, in its path from the ring to the spindle. The system produces a yarn with the characteristics of a conventionally ring-spun or ring-twisted yarn, without the use of travellers.
