Title: High efficiency continuous separation process
IPC: B01D53/04
Filed: 1983-08-11
Abstract: An extract component is separated from a raffinate component contained in a feed mixture by a process in which a unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates. A component concentration distribution is established within the system of units and divided into specific zones. Feed and displacement fluid are passed into the inlets of two of the units and extract and raffinate are taken as the entire streams from outlets of two of the units all at appropriate points on the component concentration distribution. Other inlets and outlets of the various units lying in the same zone are interconnected. At the appropriate times the inlets and outlets are shifted so as to simulate movement of the units in a direction co-current with the fluid flow and thereby enable the inlets and outlets to continually lie in the appropriate zones. Zones may be combined as zone pairs, each such pair thereupon being considered a single continuous zone.

Patent EP-0141194-A3 (EP)
Title: Circuit arrangement for frame and phase synchronisation of a sampling clock at the receiving end
IPC: H04L7/04
Filed: 1984-09-13
Abstract: With such a circuit arrangement, the sampling clock is synchronized to the frame position and the phase of the characters of a received character stream containing a "unique word" at regular intervals. In a digital correlator (1), a crosscorrelation function is generated from a unique word stored therein and from the received, sampled character stream, and a frane detection circuit (2) derives a frame clock (RT1) from those maxima of the crosscorrelation function recurring at intervals of one frame period. To achieve synchronization at any polarity of the received character stream (i.e., even if the tip and ring wires of the subscriber line are interchanged), a second frame detection circuit (3) derives a second frame clock (RT2) from those minima of the crosscorrelation function recurring at intervals of one frame period. A clock selection circuit (8) determines which of the two frame clocks is received within a limited time interval. From this frame clock, control information for representing the phase of the sampling clock (AT) is derived in a phase synchronization circuit (10).

Abstract: A transportable apparatus for controlling the production of a 
mixture of a fluid (supplied at 32) and a plurality of additives (from 
tanks e.g. 44, 46) utilizes a unified control panel (on an operator's 
platform 54) having all of the necessary controls compactly

achieved through a software controlled algorithm by which errors 
are only incrementally, rather than totally, applied to prior drive 
signals at any one time.

Patent EP-0178474-A3 (EP)
Title: Method and arrangement for the detector identification of a hazard detection system
IPC: G08B26/00
Filed: 1985-09-17
Abstract: Several two-wire signalling lines (ML) with in each case several detectors (M1, M2, ...) are connected to a central station (Z). An alarm-triggering detector causes a voltage dip (ULA ML) in the relevant line voltage (UL) and thus an alarm signal (AL ML). Using an addressing chip (AB) which is in each case allocated to one detector (M1, M2, ...), the voltage dip (ULA ML) is first generated time- limited (TV) on the signalling line (ML) and then the line voltage (UL) is disconnected for a short time (RSIP) from the signalling line (ML) by the central station (Z) and then interrogation pulses (AFIP) are output to the signalling line (ML). From the pulse sequence of the interrogation pulses (AFIP), the addressing chip (AB) determines the address of its associated detector, in which process the alarm-triggering detectors (Mi) successively cause a detector alarm (AL Mi) in the form of an abrupt rise in the line current (ILA Mi) when the detector address set is coincident with the determined address. From this, the central station (Z) determines the respective alarm-signalling detectors (Mi) with the corresponding detector address and indicates this. The associated display (MA) at the detector is activated by means of the detector alarm (AL Mi) of the relevant detector (Mi) (Figure 1). <IMAGE>
