Abstract: Abstract of the Disclosure The invention relates to a normally liquid, polyglycidyl azide product having a low polydispersity which is produced by reacting a polyepichlorohydrin product with an inorganic azide, said polyglycidyl azide product comprising predominantly secondary hydroxyl-terminated polyglycidyl azide polymer, said polyepichloro-hydrin product having a number-average molecular weight of a least 2000 and a polydispersity of less than 1.2, and comprising predominantly secondary hydroxyl-terminated polyepichlorohydrin polymer and essentially no non-hydroxyl functional cyclic ether oligomer, said polyepichlorohydrin product being made by poly-merizing epichlorohydrin in the presence of anhydrous stannic chloride catalyst, a strong carboxylic acid co-catalyst, and an alcohol as an initiator.  Polyurethanes prepared from such azide derivatives are useful as a binder for solid rocket propellants.

Abstract: Polymer-catalyst tranducers and their use for detecting one or more constituents in a sample are disclosed. Changes in conductivity of the polymercatalyst transducers as a result of electron density changes are measured to provide an indication of a particular constituent present in the sample. Such conductivity changes can be measured using a conductivity meter. The polymer-catalyst tranducers are particularly useful for the determination of glucose in whole blood.

Abstract: Unsaturated fatty acid derivatives which, besides fatty acids with two double bonds, contain fatty acids with more than two double bonds, are hydrogenated in the presence of a palladium, platinum or rhodium catalyst which has been treated with ethylenediamine or a homologue and/or a derivative thereof and at a temperature of -20 DEG to 100 DEG  C. The hydrogenation progresses very selectively while very little isomerization to trans-fatty acids occurs. For example, in the hydrogenation of soya bean oil to a linolenic acid content of 2%, the linoleic acid content only decreases to 45-52%. Under identical conditions an untreated catalyst leads to a linoleic acid content of about 35%.

Abstract: A method of and a furnace assembly for bending glass sheets. Glass sheets (6) are conveyed in bending moulds (5) supported by cars (4) along an upper transport run (2) periodically from one heating section (10) to another. In the final heating section, temperature is risen so high that a glass sheet bends by the action of heat and gravity to conform with the surface of the mould. Thereafter, a car (4) together with a bent glass sheet is lowered onto a lower run (3) and returned to the outset of a furnace (1). On cooling, the glass sheets on said lower run emit heat to the glass sheets on said upper run through the open bottom structures of cars (4). The weight and heat capacity of the cars have been made as low as possible by removing the side and back walls thereof, whereby only the front or leading walls (8) provide locking walls between sections (10) successive in the longitudinal direction of the furnace.

Abstract: A code-excited linear-predictive (CELP) coder for speech or audio transmission at compressed (e.g., 16 kb/s) data rates is adapted for low-delay (e.g., less than five ms. per vector) coding by performing spectral analysis of at least a portion of a previous frame of simulated decoded speech to determine a synthesis filter of a much higher order than conventionally used for decoding synthesis and then transmitting only the index for the vector which produces the lowest internal error signal. In other contexts, performing less critical portions of analysis on a previous frame of data has been termed "backward-adaptive". Two types of gain adaptation are used in respective implementations, both of which are backward-adaptive and one of whichis dynamic to the extent that weighting coefficients are iteration-dependent. The spectral analysis is twentieth-order to fiftieth-order linear prediction analysis. Pseudo-Gray coding is used to reduce errors induced by channel noise; and the effects of the gain and spectral analyses are taken into account in the trainingprocedures which determine the sets of vectors which are the reference or candidate excitation vectors.

Title: Injection molding manifold and nozzle having laterally clamped flanges
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/27
Filed: 1990-01-19
Granted: 1997-04-22
Abstract: A number of heated injection molding nozzles are mounted along the side surface of a melt conveying manifold.  In one embodiment of the invention, a connector collar having a tapered flange portion is bolted to the side surface of the manifold to provide each melt bore outlet.  Each nozzle has a matching flange portion with a melt bore inlet extending laterally from a side surface.          The nozzle is mounted on the manifold by securing the flange portions together by bolting a wedge clamp having two halves over the aligned flange portions.  This accurately aligns the inlet with the outlet and allows the nozzle to be rotated to a particular angular position.  In another embodiment, a melt conduit member is mounted between the manifold and each nozzle.  The melt conduit member is clamped to the manifold after being rotated to a desired angular position about a first axis.  A nozzle is clamped to the melt conduit member after being rotated to a desired angular position about a second axis which is substantially perpendicular to the first axis.  Thus, each nozzle can be located with any desired angular orientation without the melt flowing through an acute angle bend.

Abstract: A modular electronic safe arm device  (MESAD) (10) for arming and igniting an explosive is universal in application and employs a standard circuit architecture which uses application specific logic modules  (12)  and (14),  a  standard  voltage  control  module  (16),  and standard high energy firing modules (18) and (20).  In the preferred embodiment, the logic modules (12) and (14) are state machines using clocked sequential  logic and having read-only-memories.   The logic modules  (12)  and (14) generate dynamic arming signals at outputs (54) and (76)  which  cause the voltage  control  module  (16)  in conjunction with  transformer  (102),  to convert a  low voltage input (98) to a high voltage output (100).  The high  voltage  output  (100)  is  used  to  charge  firing capacitors (112) and (138) in standard high energy firing modules (18) and (20).  Logic module (14) generates two trigger signals at outputs (76) and (78) for activating the  trigger  modules  (126)  and  (148).   Charging  and triggering of the high energy firing modules  (18)  and (20) causes explosive foil initiators (108) and (134) to ignite  the  explosive.
