Patent EP-0298414-A3 (EP)
IPC: C12N9/52
Filed: 1988-07-05
Abstract: The present invention concerns a method of 
purifying acid protease which comprises contacting 
a substantially salt-free aqueous solution of acid 
protease with a weakly basic ion exchange resin by use 
of substantially salt-free water and eluting the 
thus-adsorbed acid protease with an aqueous solution 
containing an inorganic salt.  
     The purification method of the present invention 
assures a high degree of purification without use of a 
concentrated salt solution or an organic solvent and 
can be used with advantage for commercial purification 
of acid protease.
Patent EP-0324912-A3 (EP)
IPC: C12P19/60
Filed: 1988-11-10
Abstract: A method for preparing chromogenic α-amylase 
substrate compounds at substantially high 
preparative yields in a relatively short period of 
time by the transglucosylation of a chromogenic 
glucoside compound to a maltooligosaccharide chain. 
The concentration of the maltooligosaccharide 
compound is greater than about 3 times the 
concentration of the chromogenic glucoside compound 
to result in at least about 50% of the chromogenic 
glucoside compound being converted to the desired 
chromogenic α-amylase substrate compound.

Filed: 1988-12-08
Abstract: Bei Anhängern besteht die große Gefahr, daß diese beim 
Bremsen des Zugfahrzeugs ins Schleudern kommen und dann nur 
noch sehr schwierig abzufangen sind. Bekannte Auflaufbremsein­
richtungen können hier nur in sehr begrenztem Maß Abhilfe schaf­
fen.  
     Diesem Nachteil wird durch die Erfindung dadurch abgehol­
fen, daß das Gespann Zugfahrzeug (10) - Anhänger (14) entweder 
beim Betätigen der Fußbremseinrichtung oder durch einen Hand­
schalter (22) auseinandergezogen wird. Hierzu ist von dem elek­
trischen Stromkreis des Zugfahrzeugs (10), in den die Brems­
rückleuchten (24) geschaltet sind, eine Steuerleitung (62) abge­
zweigt, die von dem Bremslichtschalter (20) des Fußbremshebels 
(18) und/oder dem Handschalter (22) mit Strom versorgt werden 
kann, um dann über ein Betätigungsglied, z.B. ein Elektromagnet­
ventil eines pneumatischen Arbeitszylinders (52) die Radbremsen 
des Anhängers (14) einzurücken.

Title: Microcomputer with built-in eprom
IPC: G06F11/267
Filed: 1988-01-05
Abstract: A single chip microcomputer has a memory formed by an 
EPROM, which stores the program which controls the 
microprocessor of the microcomputer. The EPROM has a 
memory containing an array of memory elements (M-ARY), 
which are addressed by word and data lines controlled by 
address signals from corresponding decodes (X DCR, Y DCR). 
In addition, the memory has dummy word and data lines for 
addressing dummy elements (DMY, DMX). By selecting the 
dummy (word or data) line, and having the other lines (word 
or data) deselected, the dummy elements can be tested, 
thereby permitting testing of the memory even though the 
other memory elements are not erasable.
