Patent EP-0034867-A1 (EP)
Inventor: VAN DIJK WILLEM FREDERIK
IPC: G11B15/60
Filed: 1981-02-19
Abstract: A mechanical device, comprising a round, low-mass, polished, stainless steel tube or rod (1), which exerts 1 to 15 grams of pressure at, or at about, the point (7) where the tape (5) makes contact with the tape-pack onto which it is wound. The pinning down of the tape onto the tape pack prevents air entrapment at this point (air on which the tape could float) and provides a uniform, even wind. 
     The amount of pressure depends on tape width, tape tension supplied by the machine winding the tape, and tape winding speed. The tube is connected to a tube holder (2) providing means to exert pressure and a mechanism to bring the tube into working position during winding. This mechanism can be made operational by means of a clutch (10,15), or an electromagnet (17) coupled to the tapetransport command buttons of the machine.

Title: Propulsion means with two motors driven in an opposite direction for the compensation of the backlashes
Inventor: SUTER HANS-JORG
IPC: H02P5/685
Filed: 1982-05-12
Abstract: With small drive torque the motors counteract one another, with full-load output they act in the same sense upon the load, so that the backlash or play between the drive, the gearing and the load is eliminated. As the motors there are used compound motors whose armatures and shunt windings are connected in series. The series excitation currents are controlled by means of two 2-quadrant power adjustment or setting elements and the external excitation current is controlled by a 2-quadrant adjustment or setting element of small output.

Abstract: Die Erfindung bezieht sich auf das Gebiet der elektronischen Reproduktionstechnik und betrifft ein Verfahren und eine Einrichtung zur Herstellung von Farbauszügen für den Einzelfarbendruck, z. B Textil-, Dekor- oder Verpackungsdruck. Zur Gewinnung von Farbsignalen wird eine farbige Mustervorlage punkt- und zeilenweise optoelektronisch abgetastet. Aus den Farbsignalen werden Farberkennungssignale für die Vorlagenfarben und farbkorrigierte Farbauszugssignale erzeugt. Die Farbauszugssignale werden in Abhängigkeit der Farberkennungssignale von frei zugeordneten Vorlagenfarben zum Aufzeichnungsorgan für die Farbauszüge durchgeschaltet. Durch eine selektive Farbkorrektur derjenigen Vorlagenfarben, welche im Farbauszug nicht mit den vollen Dichtewerten aufgezeichnet werden sollen, und durch das gesteuerte Durchschalten von mindestens zwei Farbauszugssignalen bei der Aufzeichnung eines Farbauszuges wird die Wiedergabe des Farbverlaufs einer Vorlagenfarbe im Farbauszug verbessert. Im Farbauszug entstehen an Farbbereichsgrenzen Mischdruck-Zonen, wodurch Farbabrisse vermieden werden.

IPC: F02B31/00
Filed: 1982-06-14
Abstract: A helical intake port (16) in the cylinder head of an internal combustion engine has a long, shallow helical ramp portion (24) for producing a substantial amount of swirl of the incoming air at relatively small valve openings. The helical ramp portion extends around the valve stem (30) through an angle of say 255° and has a slope which is no greater than about 15° through at least its last 200°. The smooth flow of airfrom an upstream, back portion (18) of the port into the helical ramp portion and the subsequent swirling motion are enhanced by a diverter fence formed by a side wall of the back portion which terminates at a location adjacent and spaced apart from the valve stem and extending in a direction at the termination thereof so as to cause air travelling along the side wall to bypass the valve stem as it enters and circulates around the helical ramp portion. As the valve opening increases, the amount of swirling air introduced into the cylinder from the port is increased as large amounts of air within the port begin to bypass the helical ramp portion and flow directly into the cylinder. Such action at relatively large valve openings is enhanced by a top surface of the port opposite the cylinder head which narrows into a groove of generally V-shaped cross-section as it leaves the back portion (18) and enters the helical ramp portion (24) of the port.
