Title: Support assembly with a column and an articulated arm mounted thereon
IPC: F16M11/04
Filed: 1987-12-15
Abstract: A support assembly is provided which is intended to be capable of use particularly for supporting equipment used in medical technology. Such support assemblies are subject to the problem that sensitive supply lines must be guided through the parts of the support assembly which can move relative to one another. The design of the supporting assembly is complicated to avoid damaging these lines. Furthermore, springs and, if necessary, a brake are provided to compensate for weights. In order that the supply lines are guided in a protected manner and, at the same time, that the compensating springs and, if required, brake, are easily accessible from the outside as replaceable parts, the support assembly has a hollow space for carrying the supply lines and a compression spring for mass compensation. One bearing for the compression spring is connected to the outside of the support assembly arm and the other is connected to the moving part, such that the spring is arranged outside the hollow space. <IMAGE>

Title: Test device and method of assaying for proteins
IPC: G01N33/68
Filed: 1989-09-16
Abstract: A new and improved test device and 
method of determining the presence and concentra­
tion of proteins, such as albumin or Bence Jones 
proteins, in a test sample. The test device in­
cludes a carrier matrix incorporating a reactant 
system capable of interacting with proteins to 
produce a visually or instrumentally detectable 
and/or measurable response. The carrier matrix 
of the device can include commonly used bibulous 
matrices, such as filter paper, or a new and 
improved nonbibulous protein-permeable strip, 
membrane or layer of a polymerized urethane­
containing composition. In addition, a new and 
improved reactant system, comprising a dual indi­
cator reagent system, such as bromophenol blue, 
methyl orange and, if necessary, a suitable buf­
fer, is incorporated into the carrier matrix to 
provide improved color resolution and increased 
sensitivity to proteins, thereby affording a 
more accurate and trustworthy protein assay of 
test samples, such as urine. Furthermore, by 
incorporating the dual indicator reagent system 
into a carrier matrix comprising a polymerized 
urethane-containing composition, a dry phase 
assay for low molecular weight proteins, such as 
Bence Jones proteins, can be performed on a liquid 
test sample.

Patent EP-0363863-A3 (EP)
Title: Method and apparatus for fault recovery in a digital computing system
IPC: G06F11/14
Filed: 1989-10-07
Abstract: A method and apparatus for allowing fault recovery in a 
digital computer based control system whereby system upsets 
induced by external transient noise conditions can be 
recovered from is disclosed. A CPU (10) is coupled to its 
main memory (20) and its I/O interfaces (16) by a common 
address/data bus (22), these three elements being susceptible 
to having data thereon or therein corrupted by transient 
noise. Also coupled to the bus, but in a hardened 
environment, are first and second supplemental memories (34, 
36) which, under memory control (38), operate on alternating 
even and odd computational frames defined by the CPU's 
real-time clock to store the same words as are then being 
entered into the CPU's main memory (20). As computational 
frames are entered into one or the other of these two 
memories (34, 36) by eaves-dropping on the common bus (22), 
the other supplemental memory is transferring its contents to 
a backup memory (30) which is also housed in the noise-immune 
environment. The backup memory is connected in a read-only 
mode to the address/data bus and, because of the manner of 
operation, always contains the computational frame that is 
delayed one cycle of the CPU's real-time clock from the frame 
in progress. Should a transient upset occur, it may be 
followed by a transfer of the information from the backup 
memory (30) into the computer's main memory (20) such that 
computations can then continue with data that is uncorrupted.

Patent EP-0379693-A3 (EP)
IPC: G11C16/14
Filed: 1989-12-13
Abstract: In a method of applying a voltage pulse for 
injecting/extracting electrons into/from a non-volatile 
semiconductor memory in which high and low levels of a 
threshold voltage corresponding to presence and absence 
of storage of electrons are caused to correspond to 
binary information, the method includes the steps of 
generating a plurality of voltage pulses each having an 
ability of injecting or extracting only a portion of all 
electrons to be stored, and applying the plurality of 
voltage pulses to the non-volatile semiconductor memory 
to thereby carry out injection/extraction of all the 
electrons.  
     Since the pulse of a Fowler-Nordheim current 
flowing through the tunnel insulating film by one voltage 
pulse is short, the density of holes produced in the 
tunnel insulating film by such a current pulse is 
extremely low. As a result, the number of holes trapped 
by a plurality of Fowler-Nordheim current pulses caused 
to flow by a plurality of voltage pulses is reduced, so 
the life time of the tunnel insulating film is prolonged.

Patent EP-0375130-A3 (EP)
Title: Fuel injection nozzle
IPC: F02M45/08
Filed: 1989-11-02
Abstract: An inwardly opening fuel injection nozzle has a valve 
member which is biased into contact with a seating (15) by 
a spring (30). The force of the spring is transmitted to 
the valve member by a piston (22) slidable in a cylinder (21) 
formed in the valve member. A restrictor (27) communicates 
fuel under pressure from an inlet (26) to act on a surface 
(20) of the valve member to lift the valve member from the 
seating to allow the fuel flowing through the restrictor 
to flow through an outlet orifice (17). The piston (22) is 
also subject to the pressure downstream of the restrictor 
and when the pressure attains a predetermined value the 
piston moves relative to the valve member to uncover a 
port (28) which by-passes the restrictor to allow 
unrestricted flow of fuel through the outlet orifice.
