Title: Electronic switch arrangement
IPC: H03K17/693
Filed: 1988-11-09
Abstract: An electronic switching arrangement for use in 
e.g. a frequency-hopping radar system, for selectively 
switching one of several oscillators to an output. A 
signal input (IN) is connected to a signal output (OUT) by 
a series signal path which includes a field-effect 
transistor (FET 1), another field-effect transistor (FET 
2) being connected in shunt on the signal path, and 
respective switches (T1,T2) controlling the field-effect 
transistors (FET 1, FET 2) to turn one on whilst the other 
is turned off and vice versa. Preferably the arrangement 
includes a plurality of stages (S1,S2,S3) each comprising 
the series and shunt FET'S and their controlling switches 
(T1,T2). The switching arrangement provides a very high 
degree of isolation between its input and output when in 
the "off" condition.

Patent EP-0326100-A3 (EP)
Title: Ion-capture assays and devices
IPC: G01N33/543
Filed: 1989-01-25
Abstract: This invention presents novel separation and assay procedures which allows both the 
indicator and the capture reagents to be in solution to avoid problems of slowed 
immunoreaction kinetics. The separation procedure involves an analyte-specific soluble 
capture reagent, that is conjugated to a charged substance, and an insoluble solid phase 
material that is oppositely charged. A fluid sample suspected of containing the analyte is 
mixed with the capture reagent in solution to form a charged capture reagent/analyte 
complex. When binding is complete, the solution is contacted to the oppositely charged 
solid phase material to attract, attach, and separate the capture reagent/analyte complex 
from the fluid sample. With the appropriate indicator reagent, i.e., a second analyte-­
specific binding substance which is conjugated to a label capable of producing a 
detectable signal, both sandwich and competitive assays can be performed. The assay 
reaction complex can be separated from the solution by contact with the oppositely 
charged solid phase material, and the presence or amount of analyte is monitored by 
detecting the label of the indicator reagent.

Abstract: A photographic developing apparatus (10) of the type in which 
development is effected by passing exposed sensitive material 
(principally one for printing such as photographic paper) 
successively through a developing vessel (P₁), a bleaching/fixing 
vessel (P₂), and a rinsing vessel (W₁-W₃). The bleaching/fixing vessel is 
replenished with a mixture of concentrated processing liquid

amount of processing liquid discharged from the rinsing vessel 
as overflow is reduced, thereby alleviating the burden of 
waste liquid disposal.  
     When the exposed sensitive material to be processed is 
principally one for photographing such as negative film or 
reversal film, the material is successively passed through a 
developing vessel, a bleaching vessel, a fixing vessel, and a 
rinsing vessel, or through a developing vessel, a bleaching 
vessel, a bleaching/fixing vessel, and a rinsing vessel, so 
that concentrated processing liquid and liquid extracted from 
the rinsing vessel are supplied to the fixing vessel or the 
bleaching/fixing vessel which is immediately before the 
rinsing vessel.

Patent EP-0372974-A3 (EP)
Title: Optical disk apparatus
IPC: G11B7/095
Filed: 1989-12-07
Abstract: An optical disk apparatus comprises a light emission 
detection circuit which converts a light emission from a 
light source into an electric signal and releases it as a 
light emission signal, a photo detector which releases an 
output signal upon reception of a reflected light from a 
disk and/or stray lights, a correction signal generating 
circuit which adjusts a prescribed gain in accordance with 
the amount of stray light, and generates a correction 
signal by attenuating the light emission signal based on 
this gain, a subtracter in which the correction signal is 
subtracted from the output signal of the photo detector, 
and disk discharging means for discharging the disk from 
the optical disk apparatus, when the disk is present in 
the optical disk apparatus during the adjustment of the 
above-mentioned gain. The optical disk apparatus is 
arranged such that an optimum gain may be obtained even 
when the disk is present inside the optical disk 
apparatus, since the disk is discharged from the optical 
disk apparatus by the disk discharging means during the 
adjustment of the gain. Thereby, an accurate tracking 
error signal and focus error signal may be obtained by 
correcting the output signal of the photo detector.

Title: An erosion-controlled release system for active agents and a process for its preparation
Inventor: WENZEL UDO PROF DR
IPC: A01N25/18
Filed: 1990-01-31
Abstract: The invention relates to a system for preferably peroral 
administration with erosion-controlled active agent release 
and a process for its preparation from which preferably low 
solubility active agents are released with delay, and in a 
possible combination of suitable, high solubility active 
agents the latter are released rapidly and with only slight 
delay. The active agent(s) is (are) fabricated in the usual 
manner with adjuvants capable of swelling, e.g. micro­
crystalline cellulose or starch, with adjuvants which have 
higher affinity to water and function as swelling con­
trollers (e.g. polyethylene glycols, strongly hydrating in­
organic compounds) and optionally with additional adjuvants.  
     The pharmaceutical preparations prepared in this manner con­
tribute significantly to improving the therapy of various 
illnesses, for when suitable and preferably low solubility 
active agents are incorporated, the adjustment and main­
tenance of therapeutically effective concentrations of 
active agent are ensured.
