Abstract: ABSTRACT OF THE DISCLOSURE    A self adjusting device interposed in the lever system of a friction clutch it disclosed.  The device operatively connects a threaded adjusting ring and an axially shiftable actuating collar such that wear occurring in the friction surfaces of the clutch is automatically taken up during operation of the clutch.  The self adjusting device includes a mounting bracket secured to the clutch cover.          The mounting bracket includes a central U-shaped portion and a pair of flange portions, each extending outwardly from an end of the opposing sides of the U-shaped portion.          A pin is retained in the opposing sides of the U-shaped portion of the mounting bracket.  The pin rotatable carries a pair of hub members which effect the self adjustment of the clutch to compensate for wear of the friction surfaces.          The U-shaped portion of the mounting bracket permits visual confirmation of correct installation and function of the self adjusting device.

Granted: 1990-02-06
Abstract: ABSTRACT OF THE DISCLOSURE Electrode of reversible polarity for electro-chemical applications, especially those where the electrolyte contains also calcium and magnesium.  A multilayer structure is formed that comprises a carrier (1) of a valve metal, a conductive ceramic layer (2) applied onto the carrier and an electrocatalytically active top layer (3).  This structure results, on the one hand, in protecting of the carrier (1) and, on the other hand, in the stability of the catalytic layer (3) also in cathodic operation.  A continuous charge reversal does not damage the electrode.  The equal surfaces of anodes and cathodes may be positioned parallel or substantially parallel facing each other.

Abstract: ABSTRACT     To suppress direct-current components or high energy components at different frequencies, digital signals are often transmitted in scrambled form.  At high transmission speeds, implementation of a corresponding scrambler and descrambler is expensive  and difficult.  According to the invention, a self-synchronizing descrambler is proposed which, through parallel processing of the digital signals to be descrambled, has a comparatively low operating speed and can be easily manufactured in integrated technology.

Abstract: ABSTRACT          ION-BLOCKING COATING ON GLASS      The invention relates to barrier coatings to prevent migration of alkali metal ions from a glass surface. The barrier coatings are deposited by pyrolysis of a silane gas on the glass surface above 600°C in the presence of a gaseous electron donating compound, whereby oxygen from the glass is incorporated with silicon to form a transparent barrier coating up to 50 nm thick on the glass surface. The barrier coatings are used to prevent migration of alkali metal ions into overlying layers sensitive to alkali metal ions e.g. in glass coated with electroconductive or infra red reflecting coatings, and in liquid crystal displays.

Abstract: ABSTRACT         This invention relates to the field of data recording by optical or radiation means and in particular to optical disk technology.  It provides for media configurations which can be read by systems such as those described within.  The combinations described can provide accurate track crossing count and a more accurate track following signal than previously available.  The media employs substantially parallel tracks to act as a diffraction grating, creating a push-pull signal which varies in a sine-wave fashion as the radiation spot used for reading or writing informa-tion in the tracks moves substantially perpendicularly across a group of track lengths.  This creates the track count.  The same detector and electronics which produce the count signal from the radiation beam returned from the media may be used to keep the beam on the track centerline (i.e. for following).  The push-pull signal is used to indicate the spot's deviation from the center-line of the track.  The low frequency content of the push-pull signal is corrected by combining it with a signal from a blank area.  Another method of correcting it is with information obtain-ed from a data-type signal which is produced in response to off-centered wobbled spots.

Abstract: ABSTRACT OF THE DISCLOSURE      A coupling for connecting a tool head and a tool holder.  The tool head is inserted with an at least partially conical receiving pin into a correspondingly configured receiving bore in the tool holder.  Tool head and tool holder are actuated by clamping elements so that a contact collar on the tool head rests against the counterface of the tool holder.  The clamping device is composed of a clamping slide which is movable in the longitudinal direction of the tool holder.  In the front part of the clamping slide, movable clamping jaws are provided which cooperate with a pin fixedly disposed in the tool holder in such a manner that movement of the clamping slide initiated during insertion of the receiving pin into the receiving bore causes the clamping jaws to be pushed onto the pin and to thus grip behind an annular groove in the blind bore of the tool head, thus causing the tool head to be locked to the tool holder.

Abstract: ABSTRACT OF THE DISCLOSURE A phase detecting circuit for detecting a phase differential between a reference clock and a bit timing extracted from a demodulated signal, which is derived from a modulation wave modulated by a digital signal. The circuit successfully eliminates points of discontinuity in the phase detection characteristic of a phase detector and, therefore, accurately determines a phase differential between the bit timing and the reference clock with no regard to the magnitude of the phase differential of an input. An absolute value averaging circuit is provided for averaging the absolute values of a pluality of consecutive outputs of a phase detector. A sign majority decision circuit is provided for producing one of positive and negative signs of the consecutive outputs of the phase detector which is decided by majority. Further, a multiplier is provided for multiplying an output of the absolute value averaging circuit and an output of the majority decision circuit, the resulting product being delivered as a phase differential.

Abstract: In the roof of the tank, a cylindrical pot with an upper row of relatively large holes and a lower row of smaller overflow holes is partly filled with liquid into which the bottom end of a tube communicating with atmos is dipped to form a liquid seal which is vented automatically when the internal gas pressure in the tank rises to a level such that the liquid falls below the base edge of the inner tube. This base edge is esp. sawtoothed. The valve vents inwards if the internal pressure falls below a given level at which the quantity of liquid in the shell falls due to drainage through the overflow holes. The relative height of the bottom edge of the tube and the normal liquid level in the shell is adjustable.

Abstract: The tank rests on a platform and is divided into three compartments, the walls of which are formed by plane surfaces arranged obliquely over most of their length but terminated by vertical portions. A cover is supported on rigid cross-pieces which span each compartment and carry the mixers. Compartments I and II each have a helical screw for removing the sludge. A pump transfers the sewage from the inlet pit to compartment I; after treatment and settlement; the sludge is drawn off and the water goes to compartment II. After a second treatment it is taken to III in which it is stored for subsequent sterilisation and neutralisation; it is finally evacuated through a sand filter. The plant is compact, occupies a reduced surface area and produces a clear, odourless and colourless water. It is suitable for areas with a small population and for camping sites. The sludge can be calcined in a muffle furnace for the recovery of certain treatment prods.
