Title: Crystalline dihydrochloride of cephalosporin derivative and a method for preparation thereof
IPC: A61K31/545
Filed: 1989-10-05
Abstract: The crystalline dihydrochloride of a specific 
cephalosporin derivative is stable to heat and retains its 
antibacterial activity even after storage over long periods at high 
temperature. The crystalline dihydrochloride can be obtained by 
removing protective groups from the cephalosporin derivative wherein 
the amino group and carboxy groups are protected and then 
crystallizing the cephalosporin derivative from a hydrochloric acid 
aqueous solution. The crystalline dihydrochloride is useful for 
pharmaceutical preparations.

Abstract: Eine Anordnung zur Anreicherung von Probensubstanz für 
spektrosfopische Zwecke bei der Fließinjektions - 
Analyse mit einer Ionenaustauschersäule (48) enthält eine 
Ionenaustäuschersäule mit einem Trichter (54) der mit 
einem körnigen Ionenaustauscher (56) gefüllt ist. Die 
Ionenaustauschersäule (46) wird zur Anreicherung der Probe 
von dem spitzen, ersten Ende 46 her von Probenflüssigkeit 
durchströmt. Die angereicherten Elemente werden dann vom 
breiteren, zweiten Ende 52 her wieder durch eine 
eluierende Flüssigkeit eluiert. Es ergibt sich dabei eine 
sehr geringe Dispersion des eluierten Probenpfropfes. 
Damit kann bei hoher Analysenfrequenz eine erhebliche 
Erhöhung der Empfindlichkeit erzielt werden.

Title: An armour-piercing projectile with spiculating core
IPC: F42B12/74
Filed: 1989-12-27
Abstract: The device is employed in connection with armour-piercing 
projectiles so as to improve penetration into armour. A slender, 
firmly anchored core of a hard material (2) is inserted under the

Title: Discriminating information from noise in a communication signal
IPC: H04M9/08
Filed: 1991-08-06
Abstract: An apparatus for discriminating information signals from noise signals within a communication signal. The preferred embodiment comprises a first signal level detector, a second signal level detector, and a comparing circuit. Each of the signal level detectors comprises a digital low pass filter which employs a comparator for comparing current signal samples with previous samples and generating a representative comparator output. Each low pass filter has an attack time and a decay time, each of which characteristics is determined by an operational coefficient, the coefficient being responsive to the comparator output. The first signal level detector receives the communications signal as an input and generates a detection signal as an output; the second signal level detector receives the detection signal as an input and generates a noise detection signal as an output. The comparing circuit compares the detection signal and the noise detection signal and produces a speech burst detection signal. The operational coefficient is valued in the first signal level detector to establish a fast attack time and a slow decay time, and the coefficient is valued in the second signal level detector to establish a slow attack time and a fast decay time.
