Patent DE-2549159-A1 (DE)
Inventor: BONDYBEY VLADIMIR EDMUND
IPC: B29C65/02
Filed: 1975-11-03
Abstract: A cylindrical strand with a thermoplastic outer shell (e.g., plastic insulated wire) is bonded along its length to a similar or different cylindrical strand by laser heating. The strands are brought into contact with one another at a contact point. A laser beam of selected power and wavelength is directed at the contact point in a direction approximately parallel to the axis of the strands as the strands are carried past this point. Absorption of the light by the plastic causes melting sufficient to produce bonding. The depth of penetration of the thermal energy into the plastic is controlled by selection of the wavelength of the laser radiation relative to the absorption spectrum of the thermoplastic material. The laser power level is adjusted to control the total energy input in accordance with the strand feed rate.

Title: Internally coating plastics or similar thin tube - involves maintaining liquid column at constant level inside ascending tube length
Inventor: ROSSMEISSL RUDOLF DIPL ING
IPC: B05C7/04
Filed: 1975-12-22
Abstract: A method of maintaining constant the level of coating liquid inside a continuously moving tube of plastics or similar material is used for a vertical length of tube travelling upwards along its own axis. A rhythmical cycle of pressure is applied to the sides of the tube comprising three stages: (1) opposite sides of the tube are squeezed inwards towards its axis with a simultaneous forward movement in the same direction as the tube; (2) when the sides have been pressed together, the forward movement is continued, the sides being kept squeezed together; (3) the squeezing pressure is released while the forward movement of the pressure point still continues to travel with the tube. Used esp. for coating cellulsoe hydrate tubes. Process results in uniform application of drying heat to the coated.

Patent DE-2606402-A1 (DE)
Title: Biological investigation of particles suspended in culture medium - with variable flow rate to avoid filter clogging
Inventor: GRONOW GERNOT DR
IPC: C12M1/12
Filed: 1976-02-18
Abstract: An experimental and culture vessel for biological particles, e.g., cell constituents, cells or aggregates of cells, has filters of defined pore size on the inlet and outlet sides and is traversed vertically, contrary to the direction of gravity, by liquid culture medium. The cross-section of the interior of the vessel varies between these filters such that in steady-state flow the speed of flow of the soln. through the entire area of the inlet filter exceeds the relative sinking speed of the particles w.r.t. the medium, whereas the corresponding flow rate through the outlet filter is smaller than this relative sinking speed. Heavier particles are prevented from settling on the bottom filter and lighter particles from accumulating beneath the top filter; in this way clogging of the filters and progressive growth of particles adjacent to them is avoided. The particles, even over a wide range of size and thus of sinking speed, remain basically suspended in the upward-flowing medium.
Patent DE-2607368-A1 (DE)
Title: Line transformer for TV receiver - avoids mechanical adjustment by having inner and outer parts of HV winding wound in given way on LV winding

Title: Infinitely variable gear transmission - has plastics insert between steel and aluminium components, to compensate for differential expansion
Inventor: KREUZER HUBERT DIPL ING
IPC: F16H57/022
Filed: 1976-12-24
Abstract: The infinitely variable gearing has spherical rolling members (10) between confronting surfaces of driving and driven members. The axial loads on these members, which are made of steel, are taken through a bearing to an aluminium casing. The differential expansion of the steel and aluminium components is compensated for by a plastics ring (5) inserted between the bearing and the casing. The high coefft. of expansion of the plastics avoids changes in transmission ratio during changes from cold starting to warm running. The plastics ring may be seated in a recess in the casing so that the overall size of the gearing is unchanged.
