Title: Very low temperature casting of controlled release microspheres.
Inventor: GOMBOTZ WAYNE R
IPC: A61K47/34
Filed: 1990-05-01
Abstract: A process for preparing microspheres using very cold temperatures to freeze polymer-biologically active agent mixtures into polymeric microspheres with very high retention of biological activity and material. Polymer is dissolved in a solvent together with an active agent that can be either dissolved in the solvent or dispersed in the solvent in the form of microparticles. The polymer/active agent mixture is atomized into a vessel containing a liquid non-solvent, alone or frozen and overlayed with a liquified gas, at a temperature below the freezing point of the polymer/active agent solution. The cold liquified gas or liquid immediately freezes the polymer droplets. As the droplets and non-solvent for the polymer is warmed, the solvent in the droplets thaws and is extracted into the non-solvent, resulting in hardened microspheres.

Abstract: With a device for transporting bakery goods, such as pieces of dough for rolls or the like, which is designed as an essentially rectangular shell (1) with an open top and with profiled side walls (2,3,4), whereby an insert film (14) covers the base (19) of the device, a solution is to be created which allows simple and secure stacking and de-stacking, so that the pieces of dough do not shift and become deformed during stacking or transport, and not requiring a great deal of space. It should also be possible to manipulate the bakery goods transport device automatically. This is achieved in that the upper edges (15, 17) of two opposite side walls (2,4) of the shell (1) are provided with at least one slide-on rib (5,6), which merges at both ends into a rising and a descending ramp (7,8,9,10). <IMAGE>

Abstract: The chemical reactor vessel comprises a vessel body and a separable head attached thereto wherein the means for attaching and sealing said head to said body comprises: a seal means (59), a flange means (49,57), a shield means (61) and an attachment means (69). 
     The seal means (59) functions, in compression, to prevent leakage of fluids into and from said chemical reactor vessel. The flange means (49,57) functions to impose compressive loads to the seal means to cause the seal means to prevent leakage of fluids into and from the chemical reactor vessel. The shield means (61) are integral with at least one of the flange means, which function to substantially prevent contaminants from contacting the seal means and those portions of such flange means which are adjacent to the seal means and which function to inhibit the build-up of contaminants within and adjacent to the attaching and sealing means. The attachment means (69) function to apply compressive loads to the flange means and concurrently function to removably fix the head to the body.

Abstract: An optically active device comprising an optical fiber (10), a light source (12) and an optical device (13) is disclosed. The optical fiber (10) comprises a core made of an optical functioning glass doped with Pr 3+  as an active ion and transmits light at a first wavelength. The light source (12) generates excitation light at a second wavelength shorter than the first wavelength. The optical device (13) directs the excitation light from the light source (12) into the optical fiber (10). Then, Pr 3+  in the core of the optical fiber (10) is stimulated to emit light at the second wavelength. As a result, an optical function such as optical amplification can be effected at the second wavelength.

IPC: H04B17/29
Filed: 1991-12-20
Abstract: Interference in a high speed receive signal is effectively detected in a TDMA communications system wherein a plurality of time slots is provided within a TDMA frame. A comparator (50) is arranged to receive a first signal indicative of receive signal strength and a reference level signal. The comparator compares the magnitudes of the two signals applied thereto and outputs a comparison result signal. A delay circuit (52) is supplied with a second signal indicative of a time slot which is not in use and which delays the second signal by a predetermined time using a clock which is synchronized with the time slots of the TDMA frame. A gate circuit (54), preceded by the comparator and the delay circuit, is supplied with the outputs of the comparator and the delay circuit. The gate circuit (54) outputs a third signal which changes a logic level in the event that the strength of the first signal exceeds that of the reference level signal during the time slot which is not in use.
