Patent HR-P20020578-B1 (HR)
Inventor: DUERINGER MARKUS
IPC: B29C49/32
Filed: 2002-07-05
Abstract: An apparatus for producing hollow bodies, in particular bottles and similar containers provided with an evacuation opening, of thermoplastic includes a lower machine part and a beamlike upper machine part. The lower machine part is equipped with at least two blow molds, each provided with a cavity. A number of blowing and calibration mandrels corresponding to the number of blow molds is disposed on the beamlike upper machine part disposed above the lower machine part. One blow mold is assigned to each blowing and calibration mandrel. The blowing and calibration mandrels can be axially fed jointly toward the blow molds and can be moved with their calibration region into an orifice of the cavity until an annular shoulder of the blowing and calibration mandrels comes into contact with a counterpart face on the associated blow mold. The blowing and calibration mandrels are retained axially freely movably, within predeterminable limits, in the upper machine part. Upon joint feeding of the blowing and calibration mandrels toward the blow molds, the blowing and calibration mandrels are automatically adjustable in height relative to their outset position, counter to the resistance of a coupling medium.

Granted: 1988-05-11
Abstract: Raw water is fed into a water tank (19) to the water level (A) from a manual valve (V3) by closing a manual valve (V4) and opening automatic valves (V1) and (V2).  Next, the valve (V2) is closed and the valves (V1) and (V4) are opened.  As the water level in the tank (19) is lowered by discharging the water in the tank (19) rapidly from a sucking and discharing pipe (23), air in a siphon pipe (5) for backwashing is sucked into the tank (19) through a communicating pipe (20).

Title: Acousto-optic frequency shifter utilizing multi-turn optical fiber
Inventor: FESLER KENETH A
IPC: G02F1/01
Filed: 1986-02-07
Granted: 1994-03-11
Abstract: A fiber optic frequency shifter comprises an optical fiber (200) having an acoustic conducting medium (202) for propagation of an acoustic signal. The acoustic medium is preferably shaped as a rod, and the acoustic signal propagates longitudinally down the rod. The optical fiber is wound around the rod with plural turns such that the axis of the fiber is at an angle relative to the wave fronts of the acoustic signal. As the acoustic signal propagates through the rod, it causes stress on the portions of the fiber in contact with the rod. The stress on the fiber caused by the acoustic wave causes optical energy to be transferred between two propagation modes of the fiber. This transferred energy is shifted in frequency by the frequency of the acoustic signal. By tightly winding the turns of the fiber, high frequency shifts can be obtained.
