IPC: B01D29/27
Filed: 1989-09-21
Abstract: A filtration method has the step of feeding liquid to be filtered into a filter medium (1) between a fixed plate (2) and a movable plate (4); and reducing capacity of a filter chamber (80) formed by the medium (1) by moving the movable plate (4) in a direction in which the movable plate (4) presses the fixed plate (2) through the medium (1) so as to perform expressing filtration of the liquid and to produce cake (49). The reducing step has the step of alternately repeating at least one time an expressing pressure-increasing process for increasing pressure in the liquid in the medium (1) by a specified increment in the filtration of the liquid, and an expressing pressure-main­taining process for maintaining the pressure constant during a specified period, so that the filtration is performed under a specified pressure corresponding to a desired water content of the cake (49) to produce the cake (49). 
     A filter press (3) for employing the method has the medium (1) arranged between the fixed plate (2) and the movable plate (4) capable of approaching and moving away from the fixed plate (2). The press (3) has a driving device for driving the movable plate (4) to approach and move away from the fixed plate (2); a pressure sensor (60) arranged at one of the movable plate (4) and the fixed plate (2) and measuring pressure in the chamber (80); and a control unit (61) for controlling the expressing filtration   of the liquid by control of drive of the driving device on the basis of a signal outputted from the sensor (60).

Abstract: A device (1) for jaw-orthodontic tooth treatment. It is especially suitable for displacement (distalisation) of molars (M) in the jaw and has contact points (3) engaging on the side teeth to be treated and also an abutment splint (6) engaging on teeth. In this case the contact points (3) and the abutment or abutments (6) for displacement of the side teeth are tensioned against one another and/or pressed apart by means of a clamping device (5) or similar spacing device. The invention is characterised in that the abutment is designed as an abutment splint (6) surrounding an area of the row of teeth of the jaw to be treated at least partially in a form-adapted fashion. Such a device (1) can be accommodated almost completely in the mouth of the patient, and the distalisation force required for treatment can be generated exclusively intraorally. Also, sizable parts of the device (1) can be removed from the mouth by the patient himself and inserted there again, so that cleaning of the teeth and of the device is simple.

Abstract: Elements for making butt splices in optical fibers are simplified when formed of a deformable material and formed to define three surfaces (18,23,30) for contacting the fibers to be spliced. The surfaces are formed between two legs (20,21) of an element such that when the legs are closed onto the fibers the surfaces center the fibers and afford a resilient spring compression reserve force on the aligned fibers to maintain them in contact and the fibers are depressed into the surfaces slightly to center the fiber cores. 
     Should one fiber be larger than another, the surfaces will deform sufficiently to clamp onto both fiber ends and be deformed even by the smallest of the two fibers. Thus, the splice element 11 will center the cores of the optical fibers such that in aligned position 90% or better of the surfaces of the core portions be aligned.

Abstract: A drive arrangement comprises an a.c. induction motor (M1) having a rotary output shaft, and a drive control (Figure 2), by which the speed of rotation of the shaft is controlled. The drive control comprises a signalling arrangement (e.g. a transducer (T) supplying an analogue signal converted by an analogue-to-digital converter (ADC) or a direct digital signalling arrangement) for supplying a digital signal having a value corresponding to the desired speed of rotation of the motor shaft, together with a processor (CPU) which receives the digital signal and at least one other input and processes the digital signal in accordance therewith. The processor supplies a corresponding, but modified, digital output signal to a digital-to-analogue converter (DAC) which converts the digital output signal to an analogue control signal and supplies it to an inverter which, in response thereto, drives the a.c. induction motor. An encoder (E) is operatively connected to the output shaft of the motor and supplies monitoring signals to the processor which processes them to provide a comparison value (representing actual rotation speed of the shaft) for comparison with a value corresponding to the signal from the signalling arrangement (representing the desired rotation speed). In the event of a discrepency between the two values, the digital output signal to the DAC is modified accordingly. A further input is provided by setting means (SS7) for setting a maximum speed of rotation of the shaft as a proportion of the "basic speed" of the motor, said setting means also supplying a signal to the processor (CPU) whereby the output digital signal is modified by a corresponding reduction factor.

Abstract: A temperature-based, rate-modulated cardiac pacemaker having means for variably controlling the stimulation rate of the heart according to multiple temperature characteristics of the blood referenced to multiple moving baseline temperatures. A target rate is periodically calculated by obtaining a weighted sum of the following rate components: (1) the magnitude of a decrease in temperature below resting temperature, a first moving baseline, (2] the magnitude of an increase in temperature above a local minimum temperature, a second moving baseline, (3) the magnitude of an increase in the resting baseline above a daily minimum temperature, a third moving baseline, and (4) the absolute value of the rate of change of temperature. The resting temperature is preferably calculated over a longer interval than the local minimum temperature but a much shorter interval than the daily minimum temperature. A positive rate of change of temperature is distinguished from a negative rate of change of temperature and is used differently in the calculation of target rate. The target rate is not directly applied as the new pacing rate but is instead averaged with the previous rate in order to provide smoother transitions between pacing rates. An intermediate rate limit is included in addition to lower and upper rate limits, and rank filtering is employed in the determination of rate components.

Abstract: A coin sorter comprises a rotatable disc having a resilient surface for receiving mixed denomination coins and imparting rotational movement to the coins, and a drive motor for rotating the disc. A stationary guide plate having a contoured surface is spaced slightly away from and generally parallel to the resilient surface of said rotatable disc; the guide plate includes an area for queuing the coins on the disc into a single file of coins, and a guiding edge which engages selected edges of the coins in the single file and guides the coins along a prescribed path where the positions of the engaged edges of the coins are determined by the diameters of the respective coins. A sorting area discriminates among coins of different denominations and selects coins of different denominations for discharge from the rotating disc at different locations around the periphery of the guide plate. The sorting area includes at least two different selectors for a prescribed coin denomination for discharging coins of that prescribed denomination at two different locations around the periphery of the guide plate. A controllably actuatable shunt is associated with the first of the two different selectors for shunting coins of the prescribed denomination past the first of the two different selectors to the second of the two different selectors so that the coins are discharged at the second of the two different locations.

Abstract: An electronic switching device is shown and described, namely an inductive proximity switch, comprising a presence indicator which can be influenced from the outside, namely an oscillator (1), with a switching amplifier (2) following the oscillator (1), with an electronic switch, not shown, which can be controlled by the oscillator (1) via the switching amplifier (2), for example a transistor, a thyristor or a triac, and with a state indicator, the oscillator (1) changing the switching state of the electronic switch when the state of influence on the oscillator (1) exceeds or drops below a predetermined response threshold, the state indicator indicating different states of influence on the oscillator (1) or different switching states of the electronic switch. In the inductive proximity switch according to the invention, the problem of "unreliable range due to environmental influences" can be taken into consideration during installation and in the adjustment, due to the fact that a further state indicator (6) indicates whether the state of influence on the oscillator (1) is within a "safe range" when a metal part has approached to a predetermined switching distance or has moved away from a predetermined switching distance. <IMAGE>

Abstract: In secure data networks in half-duplex mode (e.g. telex networks), in order to avoid a loss of the code phase the half-duplex section is treated as two simplex sections for synchronisation. When data traffic is started, the transmitting generator (KGS) of the coding device (SG1) of the transmitting station synchronises the receiving generator (KG-E) of the coding device (SG2) of the receiving station by means of a message code. The two generators then synchronise their partner generator of the same coding device. For this purpose, they form a synchronising message code themselves from the message code by using a synchronising algorithm. <IMAGE>
