Title: A process and apparatus for acid-free descaling
Inventor: KERTI JOZSEF
IPC: C23G1/02
Filed: 1985-09-18
Abstract: Water mixed with pressurised carbon dioxide is passed through the object and then the pressure is reduced while the water containing removed scale is passed into a tank separated from the object. The scale is contained in the discharged water in the form of a slurry which is separated from the water in the tank and is intermittently discharged. In this way the equilibrium between calcium bicarbonate and calcium carbonate is controlled by a programmed variation of the partial pressure of carbon dioxide.

Title: Fluid density measuring apparatus
Inventor: HATSCHEK DR RUDOLF
IPC: G01N9/00
Filed: 1987-02-19
Abstract: Fluid density measuring apparatus comprises a mechanical oscillator (45), which is formed by a portion of a bent tube (43) held at two places by a holder (31). An oscillation detector (51) and an oscillation exciter (53) are arranged in the proximity of these places and each comprises at least one respective piezo-electric element, which stands in effective connection with the oscillator (45). The detector (51) is electrically connected with the exciter (53) by way of a charge amplifier, an integrator and a correction phase shifter of an electronic device (61). When the oscillator (45), which is filled with the liquid of which the density is to be determined, is brought into oscillation, the integrator additionally to a voltage amplification effects a phase shift through a phase angle of about 90 DEG  and an attenuation of alternating voltages at high frequencies. The piezo-electric elements of the detector (51) and exciter (53) are insensitive to external magnetic fields, cause practically no frequency-dependent and/or temperature-dependent phase shifts and can be arranged near to the places at which the oscillator (45) is held in the holder (31), so that they hardly disturb the oscillations. <IMAGE>

Patent GB-2187913-A (GB)
Title: Measurement of film unsteadiness in a video signal
Inventor: MINAKOVIC KARINA LYN
IPC: H04N7/26
Filed: 1987-04-03
Abstract: Unsteadiness in a video signal derived from cine film is corrected by using a motion vector measurement circuit 14 to derive from the input video signal displacement signals which represent the horizontal and vertical displacement of successive frames. A two-dimensional interpolator 18 forms an output video signal by interpolation from the input video signal under the control of a control circuit 16 in dependence upon the displacement signals. An exception detector 22 can detect pans, zooms and shot changes and inhibit the interpolation control when such occur. The motion vector measurement is made by determining the differences between adjacent pixels on the same line, corresponding pixels on adjacent lines, and corresponding pixels on adjacent frames, and combining the resultants in accordance with expressions (3) and (4) herein, which are based on a first-order-truncated Taylor expansion. <IMAGE>
Patent GB-2208257-A (GB)
Title: Overvoltage protector
Inventor: PATHAK VIJAY KUMAR
IPC: H01L29/87
Filed: 1987-07-16
Abstract: An overvoltage protector consists of a 4-layer diode having a buried region (16) located adjacent to the central junction of the diode and of greater impurity concentration than the layer (1) of the same conductivity type adjacent to it, so that the current through the diode preferentially flows through the buried region. The buried region is of smaller area than the emitter junction, so that avalanche multiplication in the buried region determines the breakover current of the diode. The holding current of the diode is set by parts of the second layer (2) which perforate the first, or emitter, layer (3) thereby forming a resistive path in parallel with the emitter junction. A device for protecting against voltages of different polarities is described comprising two such diodes formed in parallel and connected in opposite senses with a common third layer. <IMAGE>

Title: A short-circuit and ground fault detecting apparatus for automotive electromagnetic clutches
Inventor: MIMURA MUNEHIKO
IPC: F16D48/06
Filed: 1990-07-02
Abstract: A short-circuit and ground fault detecting apparatus for an automotive electromagnetic clutch (4) consists of a clutch current calculating means (2), a clutch current control means (1), and a clutch output circuit operation detecting means (5). The clutch current control means has two output transistors (11 and 12) on the positive and negative side of the clutch (4), serving as switches connected to current supply mechanisms of the clutch. The clutch is energized and de-energized by turning on and off the transistors. The voltages (Va), (Vb) at the transistors are sent to the detecting means (5), where they are removed of ripples and converted into digital signals and fed back to the current calculating means (2), which in turn checks the digitized voltages for any fault. In the event of a failure of the clutch current control means (1) owing to a short- circuit or ground fault, the clutch current calculating means (2) takes the resultant abnormal voltages as an indication of the fault and takes necessary actions to turn off the two transistors, thereby releasing the clutch and protecting the transistors from damage. <IMAGE>
