Abstract: An interface arrangement (SSE) is provided for the transmission of communication cells which occur at a specific transmission bit rate on a feeding line (ZL) and which are associated with different virtual links or virtual paths via inputs of an ATM communications arrangement (ATM-K) designed for a lower transmission bit rate. This interface arrangement has a plurality of handling arrangements (MBHE, SBHE1, ..., SBHE3) which are connected to the feeder line and in each case on the output side to at least one of the aforementioned inputs. Under the control of one of the handling arrangements acting as the master handling arrangement (MBHE), the communication cells are cyclically distributed among all the handling arrangements and subsequently forwarded to the ATM communications arrangement with the addition of a sequential number which is currently valid for the respective virtual link or path. <IMAGE>

Abstract: The piston (17) of a reciprocating hydraulic actuator (10) carries a pump (23) which is driven by an electric motor (25) and which supplies oil from the low pressure chamber (15) of a cylinder to the high pressure chamber (16) thereof in order to advance the piston. An exhaust valve (30) in the piston (17) is normally held in a closed position by magnetic force created by energizing a coil (50) and when closed, enables pressurization of the high pressure chamber (16) of the cylinder. When a second coil (70) is energized, the magnetic field of the first coil is negated and the valve (30) is opened by a spring to permit oil to exhaust from the high pressure chamber (16) to the low pressure chamber (15) and permit a second spring (21) to retract the piston (17). If both the pump motor (25) and the second coil (70) are de-energized, the first coil (50) keeps the valve (30) closed and causes the piston to remain in a commanded position. The actuator may be controlled by a floating single pole, double throw switch and its piston (17) is automatically shifted to its fully retracted position by the second spring (21) if electrical power to the actuator is lost.

Abstract: A groove (36) is formed in a lower chamber insert (12). The groove (36) has a bottom surface (32) and side surfaces (34) extending upwardly from opposite side edges of the groove bottom surface (32). The groove side surfaces (34) prevent injected fuel from flowing around a connecting hole (26) to the rear thereof. Further, the inside surface (30) of the lower chamber insert (12) where the fuel collides with it, is inclined so that the geometric axis of reflection (38) thereat is positioned downstream of the injection axis (28) in the direction of the swirling flow (40). Due to this inclination, the fuel is directed by the inertial force of the injected fuel, towards the connecting hole (26), so that the injected fuel flows smoothly into the connecting hole (26).

Abstract: Process for controlled dissolving of quartz and its application to the chemical machining of the thickness or of the shape of quartz laminae intended to form resonators. The dissolving solvents employed until now (hydrofluoric acid and ammonium bifluoride) are not satisfactory because they deteriorate the surface quality of the laminae. According to the invention it has been found that it is particularly advantageous to employ baths in which the main solvent is an alkali metal (lithium, potassium or sodium) fluoride or hydroxide or an ammonium hydroxide or a mixture of these compounds.
