Abstract: -- A MIXING VALVE --Abstract A single mixing valve    has a ball-like valve plug with hot and cold water inlet ports and outlet ports and a valve housing having a valve seat face of the same form as the plug. The housing has inlet ducts for the hot and cold water to be mixed and an outlet duct for the mixed water, the ducts porting into the face. A driving part is joined with the plug and is able to be rocked therewith for changing the rate of outlet of water from the valve and to be moved for changing the mixing ratio of the hot and cold water. The driving part is limited in its rocking motion to motion about a rocking axis running through a middle point of the plug and is limited to turning about an axis of turning running through the middle point. The valve has a guide plate, which may be turned in a plane parallel to the rocking axis of the driving part, with same in relation to the housing. The plate has a slot in which the driving part is keyed while being able to be moved along the slot. with this system it is not possible for the plug to be moved into skew positions.

Abstract: Abstract of the Disclosure A floating lock mount for a seat belt retractor is provided for application in situations where the seat or seats served by the retractor is shifted forwardly or rearwardly by the user so as to accommodate the positioning of legs and other physiognomy and to adjust the seating to the user. A track is provided which generally parallels the fore and aft move-ment of the seat. The retractor is attached to the seat frame and is connected to a sleeve operably on the track. As the seat is moved, the retractor and sleeve moves and relocates on the track in accord with fore and aft movement and vertical displacement. A plurality of ratchet teeth are provided on the track and spring means bias the retractor from lock engagement against the teeth. However, under upward stress by the webbing or seat belt, as felt in a sudden deceleration or protection of the body of the user, then the retractor tilts and pawl means connected to the retractor grab the ratchet teeth and secures the retractor against any further movement. Seat belt loads are transferred to the floor of the vehicle and the vehicle frame via the track.

Abstract: ABSTRACT OF THE DISCLOSURE       The surfaces of cylinders or fabrics moving in the press or drying section of a paper machine induce layers of air to move along with them.  These layers of air produce positive and nega-tive pressures at the clefts defined by the fabric/web and by the cylinder surfaces.  These positive and negative pressures are detrimental to the mutual support contact between the web and the fabric.  A method is suggested by means of which the said de-trimental positive and negative pressures are reduced.  The pressure levels at the clefts are adjusted by blowing air in directions opposite to the direction of travel of the web/fabric from blowing means close to the web/fabric, and possibly also in directions opposite to the direction of travel of the cylinder This results in air being ejected from the pressurized clefts or from zones facing the clefts at negative pressure on the opposite side of the web/fabric.

Abstract: ELECTRICAL IGNITION SYSTEM FOR CATALYTICALLY HEATED CURLING DEVICE               ABSTRACT OF THE INVENTION A hair curler for rolling up the hair having a cylind-rical rod body containing a catalytic healing device.  The rod body is permanently affixed on a handle which is designed as a fuel tank.  A thermostatically controlled valve device, between the fuel tank and the rod body, regulates the fuel supply from the fuel tank to the catalytic heating device.  An opening allows air to enter the chamber which contains the catalyst.  An igni-tion device is situated at the free end of the cylindrical rod body.  The ignition device is activated by means of an operating key which closes an electrical circuit, to heat an incandescent filament, and thus to initiate catalytic combustion at the catal-yst.  A chamber is situated between the battery and the combus-tion chamber.  This chamber is flushed through by ambient air and inhibits heat flow.  The electrical conductors of the ignition device are conducted through this chamber.

Abstract: ABSTRACT METHOD AND APPARATUS FOR SIGNAL-EYE TRACKING IN DIGITAL TRANSMISSION SYSTEMS Signal-eye tracking is achieved by forming a sample at a regeneration sampling time (e,g., 404), a first sampling time (e.g., 401) and a second sampling time (e.g., 402).  The first and second sampling times respectively precede and succeed the signal-eyes while each regeneration sampling time occurs within the signal-eyes.  The amplitude of each sample represents the amplitude of the digital signal at the sampling time relative to a reference level (e.g., 301,302 or 303) which passes through one of the signal-eyes.  A first comparison signal is generated by comparing the  amplitudes of the samples at the regeneration and adjacent first sampling times.  Similarly, a second comparison signal is generated by comparing the amplitudes of the samples at the regeneration and adjacent second sampling times. The difference between the first and second comparison signal is then averaged to form an error signal.  The error signal varies with movement of the signal-eyes relative to the regeneration sampling time.  In one embodiment of the invention this error signal is used to align the regeneration sampling time with a predetermined position within the signal-eyes.
