Title: Electroconductive layer for precision resistors - contg. carrier particles coated with metal and carbon and embedded in binder
Inventor: AMBROS PETER DIPL CHEM
IPC: H01B13/00
Filed: 1976-04-10
Abstract: Electroconductive layer contg. electroconductive particles embedded in a binder, esp. for use as a resistor, is produced by coating refractory carrier particles (20 mu) with a metal cpd.; reducing it to a metal with reducing gas at an elevated temp.; covering the metal coating with a carbon coating by pyrolysis of a carbon-contg. substance; and embedding the doubly coated particles in a non-conductive binder such that the conductivity is preserved to a predetermined degree. A fine adjustment of the conductivity can be carried out by controlled oxidn. of the coated particles (before or after carbon deposition). This material is esp. suitable for mfr. of precision resistors, because of the low temp. coefficient of the electric resistance. The carbon coating is compatible with polymers so that the latter may be used as binders. If Ag is used as a metal coating, the migration of its atoms is prevented by the carbon coating. The material is relatively inexpensive and has long service life.

Patent DE-2725917-A1 (DE)
Inventor: BRUEGGER HANS
IPC: F15B13/04
Filed: 1977-06-08
Abstract: In order to damp the hydraulic shocks which arise upon reversing the five-chamber directional control valve, the control plunger (7) has milled recesses (6, 19) with control edges (15, 20) on its end collars (23, 24). As a result, spring spaces (9, 18) are always filled with control oil from the return chambers (8, 21) in the end positions of the plunger, and, during a subsequent switching operation, the control plunger (7) must necessarily displace a volume of control oil via restrictions (16, 17). This brings about a reduction of its switching speed and a damping of the reversal shocks. The valve is of simple construction and can therefore be manufactured at a favourable cost. <IMAGE>
