Title: Voice coding/decoding system having selected coders and entropy coders
IPC: G10L19/18
Filed: 1990-06-28
Abstract: VOICE CODING/DECODING SYSTEM HAVING SELECTED          CODERS AND ENTROPY CODERS                  ABSTRACT OF THE DISCLOSURE    Disclosed  is a voice  coding/decoding  system having  a transmitting part for transmitting a coded signal of an input voice signal at a bit rate lower than a predetermined trans-mission bit rate and a receiving part for receiving and decoding the coded signal transmitted from the transmission part.   To enable the coding and transmitting of an input voice signal in an optimum state without passing through a buffer memory and without having a negative influence on the coder, the transmit-ting part provides coders for coding the input voice signal and groups of entropy coders.  The inputs of the entropy coders in each group are connected to the output of one of the plurality of coders.  The transmitting part further provides an evaluation part for evaluating the characteristics of the outputs of the coders and the entropy coders.   The evaluation part extracts those entropy coders having output bit rates lower than the transmission bit rate and extracts from the coders connected to the extracted entropy coders, a coder having the best output characteristic.  Then, the evaluation part outputs a selecting signal indicating the combination of the selected coder and an entropy coder from the extracted entropy coders.  The transmit-ting part further provides a selecting part for selecting, in response to the selecting signal, the codeword passed through the combination of the coder and the entropy coder to be transmitted.

Title: Rapid change die assembly
Inventor: MILLER WILLIAM H
IPC: B29C48/49
Filed: 1990-09-17
Abstract: Abstract An assembly for configuring extrudate flow having a die  assembly  and  an  extruder  switching  assembly  for conveniently changing the profile and extrudate material of the extrusion being manufactured.  The die assembly includes a die head having a feed member passage for movably supporting a feed member in the die head, and first and second die head passages, and corresponding first and second die surfaces which are located intermediate the die surfaces and feed passage.  The feed member includes a feed passage and a feed opening for supplying extrudate to the die head.  Addition-ally, the feed opening has a first central axis, and the first and second die head passages have second and third central axes, respectively.  The first central axis and second central axis are movable with respect to one another upon movement of the feed opening or first die head passage with respect to the other of the feed opening or first die head passage, respec-tively.  The first central axis and third central axis are also movable with respect to one another upon movement of the feed opening or second die head passage with respect to the other of the feed opening or second die head passage, respec-tively.  Movement of the axes correspondingly configures extrudate exiting a die head passage when the feed opening is in communication with the respective die head passage.  The extruder switching assembly includes a housing and an extruder switch member having extrudate supply passages.  The housing supports the extruder switch member for movement between positions in which the die assembly is supplied with extrudate material from either a first or second extruder.

Patent CA-2048061-A1 (CA)
Inventor: GULOTTA JOSEPH A
IPC: C03C4/02
Filed: 1991-07-29
Abstract: A green tinted, ultraviolet absorbing glass is obtained by the addition of colorant to a standard soda-lime-silica base glass composition and a colorant includes less than 0.5 weight percent of cerium oxide (CeO2), greater than 0.85 weight percent of total iron expressed as Fe2O3 and a ratio of ferric iron expressed as FeO to total iron of less than 0.275. The glass has a low ultraviolet transmittance, viz., no greater than 31 percent over the wavelength range of 300 to 390 nanometers at a reference glass thickness of 3.9 millimeters. An advantage of the glass of this invention over competing ultraviolet absorbing glass is the use of larger amounts of total iron and smaller proportions of iron in the ferrous state to obtain the low ultraviolet transmittance. In this manner, the amounts of cerium oxide which is expensive is reduced.

Title: Vaccine and immune serum against drugs of abuse
Inventor: CERNY ERICH H
IPC: A61K39/385
Filed: 1991-01-17
Abstract: Addictive drugs like cocaine, heroin or amphetamines are spreading in an epidemic manner in the western world and are an important factor in the spread of the acquired immune deficiency syndrome AIDS(multiple use of infected needles among drug addicts). The present invention describes a vaccine and immune serum against drugs. The vaccine contains the drug bound to a carrier protein in order to produce antibodies against the drugs in the affected person. The use of the drug in the presence of the antibodies deactivates the drug. The desired drug effect is thus eliminated and the vicious circle between stimulation and application is broken.

Abstract: ABSTRACT     The  system  of  this  invention uses  both  a process  and  apparatus  for  printing  an  image  on  a removable thicker dielectric layer than conventionally used  in other systems.   The dielectric layer is at least 0.2 mils thick and is removed from  the system after  it  is imaged,  developed  and  fixed.   Several alternate  ways  are  used  to imagewise  charge  the dielectric   layer.      The   toner   used   preferably incorporates a resin of the said family resin as used in the dielectric layer or layers.  The imaged layer may be attached to a base such as a tile or wallpaper support  structure.   The  base  support  substantially strengthens the dielectric  layer which is  important for shipping, storage, ultimate use and durability.
