Patent EP-0287024-A3 (EP)
Title: A tubular belt conveyor
IPC: B65G15/08
Filed: 1988-04-12
Abstract: A tubular belt conveyor comprises front and rear end rollers, an endless belt movable between the two rollers and a plurality of guide frames which support the belt. The belt is rolled up into tubular form in which powdered or granular material is transported continuously without scattering. Some of the guide frames are arranged such that their axes are laterally away from the longitudinal axis of the belt. Accordingly, the conveyed material such as a long piece does not bamp against the belt wall, whereby it is prevented to damage the belt or interrupt the running.

Title: A non-stop cooling system for a computer
IPC: G06F1/20
Filed: 1988-12-02
Abstract: A non-stop cooling system is provided for a computer 
system. The cooling system uses two fans both normally 
operating at reduced capacity to cool the system. A 
failure of one fan causes the other fan to operate at full 
capacity to cool the system. Each fan forces air through 
a door which closes when the associated fan fails allowing 
the failed fan to be removed without shutting down the 
system.

Abstract: Die beschriebene Schaltungsanordnung zur Überwachung ei­
nes Binärsignals enthält zwei Flip-Flops (F1, F2), die 
von einer Steuereinheit Steuerimpulse erhalten, deren Ab­
stand mindestens so groß wie die charakteristische Warte­
zeit ist. Die charakteristische Wartezeit ist die Zeit, 
innerhalb derer im zu überwachenden Binärsignal - Normal­
betrieb vorausgesetzt - mindestens ein Pegelwechsel auf­
tritt.  
     Damit die beiden Flip-Flops vom gleichen Takt (T) getak­
tet werden können, ist jedem von ihnen eine Gatterschal­
tung (G1, G2) zugeordnet, deren Ausgang mit dem Datenein­
gang des zugeordneten Flip-Flops verbunden ist. Sendet 
die Steuereinheit einen Steuerimpuls aus, dann wird mit 
Hilfe der ersten Gatterschaltung (G1) dafür gesorgt, daß 
das erste Flip-Flop (F1) in seinen gesetzten Zuschaltzu­
stand übergehen kann, während der Schaltzustand des zwei­
ten Flip-Flops (F2), bedingt durch die Wirkung der zwei­
ten Gatterschaltung (G2), an den invertierten Schaltzu­
stand des ersten Flip-Flops (F1) angeglichen wird. Bei 
Abwesenheit von Steuerimpulsen kann das erste Flip-­
Flop (F1) nur durch eine binäre 1 im zu überwachenden Bi­
närsignal in seinen rückgesetzten Schaltzustand gebracht 
werden, während das zweite Flip-Flop (F2) seinen Schalt­
zustand nicht ändern kann.

Title: Inverter control method and apparatus
IPC: H02J3/36
Filed: 1988-02-29
Abstract: A control for an inverter operable for converting direct voltage and current to alternating voltage and current. The inverter includes a plurality of electrical valves each operable to conduct current in a single direction upon the application of a positive voltage in the forward direction and the receipt of a trigger pulse. The control provides successive trigger pulses for commutating the current between successive valves at predetermined electrical firing angles and includes a voltage-time area calculating circuit for calculating the maximum permissible firing angle which will permit successful commutation. An inverter commutation failure prevention circuit is coupled to the alternating current network for detecting abnormal voltage conditions and for producting a control signal functionally related to any deviation in the alternating voltage from the expected voltage condition. The control is responsive to the control signal for reducing the electrical angles of the trigger pulses provided to the valves.

Title: Assay and apparatus using a lateral flow, non-bibulous membrane
IPC: G01N33/558
Filed: 1988-06-01
Abstract: A method and apparatus for conducting specific binding pair assays, such as immunoassays, is described. A porous membrane capable of non-bibulous lateral flow is used as assay substrate; a member of the binding pair is affixed in an indicator zone defined in the substrate. The sample is applied at a position distant from the indicator zone and permitted to flow laterally through the zone; any analyte in the sample is complexed by the affixed specific binding member, and detected. A novel method of detection employs entrapment of observable particle in the complex. Blood is a particularly preferred sample as the red blood cells can be used as the observable particles for detection of the complex.
