Title: Process for the production of hollow bodies from thermoplastic material
Inventor: KIEFER ERICH
IPC: B29C48/475
Filed: 1990-10-27
Granted: 1995-05-16
Abstract: The invention relates to a process for the production of hollow bodies from thermoplastic material by means of extrusion blow molding in which discontinuously produced preforms are expanded in a blow molding mold.        In that process, at least during a part of the filling phase which is typical of such a process, for an extrusion head, the distance covered by an  ejection piston associated with a storage chamber and the speed at which the ejection piston is displaced within the storage chamber by the plasticised material are detected and compared by a central  control  and  regulating device  to  the  respective  reference values.  On the basis of the result of the comparison operation at least one operating parameter of the process, for example the delivery output of the extruder or the extent of the emptying stroke movement of the ejection piston can then be adapted while still in the same working cycle in such a way that substantially the required preform volume is ejected.

Title: Blends of immiscible polymers having novel phase morphologies
Inventor: PUCCI MARK S
IPC: C08L77/00
Filed: 1992-03-11
Granted: 1997-01-14
Abstract: Unique phase morphologies of incompatible thermoplastic polymers, including a higher melting temperature polymer and a lower melting temperature polymer that has been sufficiently chemically compatibilized to form a stable interface in a two-phase system, are achieved by pre-melting the higher melting temperature polymer, adding the compatibilized lower melting temperature polymer in solid form thereto, and thereafter melting the lower temperature polymer with mixing. In particular, in poly(ethylene vinyl alcohol)/modified polyolefin systems, compositions containing between about 35 and about 55 wt. percent EVOH are formed in which the poly(ethylene vinyl alcohol) exists as a continuous phase and the modified polyolefin exists as discrete domains dispersed therein.  Such blended compositions have gas barrier properties comparable to homogeneous poly(ethylene vinyl alcohol).

Granted: 1999-02-02
Abstract: A system for the synchronization of encryption and decryption in a duplex cellular radio system in which an encrypted call may be switched from one cell to another. At the instant of handoff, a rapid first resynchronization means temporarily seizes the voice channel in one direction only and transmits synchronization information in such one direction. The first resynchronization means ceases to transmit the synchronization information and releases such one direction of the voice channel as soon as an indicator of successful synchronization is detected in the other direction. Transmission of speech traffic in such one direction is then resumed after such detection of successful resynchronization. To avoid occupying such one direction with continuous transmission of the synchronization information in the event successful resynchronization has occurred but has not been detected due to faulty transmission in the other direction, an upper limit is set on the length of time which the first rapid synchronization means may cease such one direction. After such timeout, resynchronization information may be provided by a second resynchronization means at a slower rate through a slow rate control channel bit stream which is multiplexed with the traffic data.
