Patent EP-0210710-A3 (EP)
IPC: A47C5/02
Filed: 1986-02-13
Abstract: This invention is related to a kind of novel structure for bind­
ing the inlaid rattan network for the rattan seating furnitures, es­
pecially provides a kind of simple and ready method for doing the job 
of binding the rattan network. And, no matter whether in flat surface 
or curved surface, the rattan network bound on it will be in a flat 
and tight binding condition. It is only necessary to make an outer 
frame and an inner ring according to the size and shape of the inte­
gral outer appearance of the seat, or seat back, or the integrated 
seat and back in one piece of the seating furniture to be bound with 
the rattan network, with a rattan network of the size a little larger 
than seat surface, seat back, or the integrated seat surface and back 
in one piece to be placed on the top of the inner ring; then, with the 
help of such machinery as punching machine or the like, the outer frame 
is placed on the rattan network covered inner ring and punched and 
pressed tightly, or further, filled or painted with viscous gum or 
melting liquid for further tightening combination. Thus, a rattan net­
work type seat surface, seat back, or integrated seat surface and back 
in one piece is finished up, and can be conveniently matched with plas­
tics, metals, or materials other than wood and rattan to form the novel 
structure of inlaid rattan network part to be assembled to various 
types of seating furnitures such as chairs, stools, and couches, etc. 
through integrated operation of total automation.

IPC: G01N33/542
Filed: 1986-03-04
Abstract: Light generated by one or more chemical reactions in a dis­
crete array is determined, both as to emissions per reaction and 
as to relative location of the reactions, e.g. using a system com­
prising:  
a sample carrier having spaced-apart discrete areas each 
containing a reactant capable of emitting light photons if a 
reaction takes place;  
a photon receiver, for receiving photons emitted from each 
reaction simultaneously; and  
a signal generator coupled to the photon receiver, for 
generating a signal representing the x-y location of each reac­
tion.  
     The signal generator may be a photomultiplier, charge-­
coupled device or vidicon tube. The invention is particularly 
suited to the determination of reactions and non-reactions, e.g. 
between an array of labelled antibodies and a specimen poten­
tially containing one or more complementary antigens, in an im­
munoassay.

Patent EP-0234374-A3 (EP)
IPC: B01D29/01
Filed: 1987-02-07
Abstract: Bei Behandlungsbädern, z. B. von Stahl oder Blechen, ist 
es bekannt, deren Konzentration ständig zu überwachen. 
Hierzu muß ein vom Badschlamm gereinigter Flüssig­
keitsstrom zu der Überwachungsapparatur geführt werden. 
Bisher hat man dies dadurch erreicht, daß ein Volumenstrom 
dem Bad entnommen wurde, über ein vertikal stehendes Fil­
ter geleitet und der benötigte Flüssigkeitsstrom zur 
Untersuchung auf der einen Seite des Filters abgenommen 
wurde. Aufgrund der Anordnung des Filters setzte sich dies 
sehr schnell zu. Erfindungsgemäß wird dies dadurch ver­
hindert, daß das Filter horizontal liegend angeordnet ist und 
der Flüssigkeitsstrom entgegen der Schwerkraft geführt wird 
und daß nur noch ein wesentlich geringerer Teil als bisher 
das Filterelement durchströmt. Die durchströmte Menge ist 
abhängig von der benötigten zu untersuchenden 
Flüssigkeitsmenge.

Title: Security fuse circuit for programmable logic array
IPC: H03K19/177
Filed: 1988-04-13
Abstract: One of the programmable elements of the array (20) is designated as a security element (22), and its output is coupled to a latching mechanism (30). The output of the latching mechanism (30) is coupled to a mechanism (36) for disabling the read output of the array (20). The latching mechanism (30) is enabled for a short time by a pulse when power is applied to the circuit. Thus, when power is first applied, the security fuse (22) has not been set and the latch output will allow data to be read. While power is applied, all of the programmable elements can be set, including the security element (22). All the elements, including the security fuse (22), can then be verified by reading them out. When power is turned off and subsequently reapplied, the latch (30) will then be enabled and the set security fuse level will appear at the latch output, thereby disabling the reading out of the program data. The present invention thus allows verification of the setting of the security fuse (22) and verification of the other programmable elements after the security fuse (22) has been set.

Title: A variable speed transmission unit
IPC: F16H9/12
Filed: 1988-08-19
Abstract: A variable speed transmission assembly comprising a 
variator (3) connected between main power input and output 
shafts (1 and 4). A power split differential gear 
assembly (2) splits power from the input between the 
output and the variator. The variator output is connected 
to a ratio spread differential (5), one output of which is 
connected to the main power output shaft, the other output 
also feeding the variator input. The main advantage is 
that the variator handles less than one half of the total 
power. Secondly, the variator input runs at a speed which 
is inversely proportional to the output speed. In this 
way, the variator is better able to handle its power 
through put.

Title: Method to signal the free and occupied state of track sections in railway shunt arrangements, and device to perform this method
IPC: B61L17/00
Filed: 1989-04-24
Abstract: During shunting, it occasionally occurs that a points-circuit zone is prematurely reported as free below an unusually long vehicle by the associated track free report device. Special measures then have to be taken in order to prevent the points turning below this unusually long vehicle. For this purpose, the invention provides for the free report signal of the track free report device (GFAW) only to be evaluated as a free report of the associated track section if it has been ensured that all the axles of a vehicle (FZ) or a group of vehicles travelling over the section have previously travelled into the section. For the first section in the driving direction of a track system, this is determined by an indicator (EL) which detects the completion of the passing of the vehicle or of the group of vehicles. The indicator signal (EFWA) which occurs earlier in time is connected to the free report signal (GFWA &uarr& ) of the track free report device to form a vehicle end code (FEZA) which indicates that the vehicle or the group of vehicles has left the first track section. This vehicle end code (FEZA) is connected, as the vehicle or group of vehicles advances further, to the free report signal (GFZA &uarr& ) of the track free report device of the following track section to form a new vehicle end code (FEWB) for this section which indicates that the second section is completely cleared. This process continues as the vehicle or group of vehicles advances from section to section. <IMAGE>

noise superposed, for instance, on a power supply line 
is supplied through the first and second photoelectric 
converting circuits to the first and second input 
terminals of the differential amplifier with the same 
phase as each other, so that the noises are cancelled 
in the differential amplifier.
