Patent EP-0290359-A2 (EP)
Inventor: SCHICK MARTIN FREDERICK
IPC: C08L67/00
Filed: 1988-05-04
Abstract: Compositions useful as printing inks or as dry or wet concentrates for the preparation of inks, comprising substantially homogenous blends of from about 0.1 to about 50.0 wt. % water dispersible polyurethane, and conversely from about 99.9 to about 50.0 wt. % water dispersible polyester, and preferably containing from about 1.0 to about 95.0 wt. % of a solvent system comprising water or water admixed with cosolvent, the cosolvent comprising up to about 30.0 wt. % of the solvent system. These blends show exceptionally marked improvements in certain physical properties such as: stability of viscosity to ambient and process conditions; linearity of viscosity change with water dilution; consistency of viscosity for a great variety of pigments; and greatly improved shelf-life (no significant polymer segregation or layering). Such properties greatly enhance the utility of these blends for use in pigmented or dyed printing inks and in other substrate coating formulations which may or may not contain colorants. Also disclosed is a process useful for the preparation of such compositions.

Inventor: FAZIO JAMES ANTHONY SR
IPC: H03K4/69
Filed: 1988-09-27
Abstract: A method and apparatus for the fast retrace of the electron beam in a cathode ray tube are disclosed. A deflection signal is presented to a cathode ray tube deflection system upon the detection of the end of the retrace period of the deflection signal so that a cathode ray tube electron beam can scan across the screen of the cathode ray tube. Upon detecting the beginning of the retrace period of the deflection signal, a forcing signal is presented to the cathode ray tube deflection system. The presenting of the forcing signal to the deflection system quickly reverses the direction of the current flow through the deflection system and allows for the electron beam to slew to its initial position and settle before the end of the normal retrace period.

Abstract: In a switching apparatus for movable parts of a railway point in the diverging region of a point, in particular tongue rails (3), monorail deflection devices or movable stock rails, in which the movable rails (3) can be moved to bear against rigid point parts (1, 2), the movable rails (3) are supported in their bearing position by means of supporting bars (4) which run in the longitudinal direction of the rails and are guided displaceably on the sleepers or baseplates in the longitudinal direction of the rails. In this arrangement, the supporting bars (4) are designed as an actuating member for the switching and comprise thrust supports (7) which interact with thrust supports (10) of the movable rails (3) for the purpose of displacing the rails, at least one of the interacting surfaces of the thrust supports (7, 10) of the rail (3) and/or supporting bar (4) being formed by a wedge surface (8) which merges into a supporting surface (9) which is essentially parallel to the longitudinal direction of the supporting bar (4), which supporting surface (9) interacts with the thrust support (10) of the rail (3) in the bearing position of said rail. As a result, a reliable and exact switching for points, in particular high-speed points having a large radius of curvature, is made possible in a simple manner (Fig. 1).

IPC: G03C3/00
Filed: 1989-03-22
Abstract: In a film cassette (1), a film spool (5) is rotatable independently of a pair of coaxially spaced disks (51, 53). The two disks (51, 53) have respective annular circumferential lips (59, 61) which prevent the outermost leader convolution (47) of a film roll (37) wound on the spool core (23) from clock-springing into contact with the cassette shell (3). When the spool core (23) is initially rotated, the disks (51, 53) can remain substantially stationary and the film roll (37), since its inner end (39) is secured to the spool core, tends to expand radially to ensure a non-slipping relation between the outermost leader convolution (47) and the circumferential lips (59, 61). Then, rotation of the spool core (23) must rotate the disks (51, 53) and stationary internal spreaders (65, 67) will deflect successive portions (59′, 61′) of the lips (59, 61) to an axial dimension exceeding the film width, thereby allowing corresponding portions of the outermost leader convolution (47) to exit from the radial confinement of the lips. Stationary internal guides (73, 75) direct the freed forward end (45) of the outermost leader convolution (47) to the cassette opening (25). Sufficient film thrust is provided by the spool core (23) as it is rotated, to thread the film leader (43) along a predetermined path from the cassette opening (25), to the outside of the cassette shell (3).

Abstract: A High Speed Charge-Coupled Sampler and Rate Reduction Circuit is disclosed. The present invention allows measurement of high frequency input signals while reducing actual data rates for a series of accurately interleaved sampler data streams. The Charge-Coupled Sampler [10] includes a source means [12] for providing a steady supply of charge and a sampling gate means [14] adjacent to the source means [12] for dividing the charge stream into discrete charge packets separated uniformly in time. An input gate means [16], adjacent to the sampling gate means [14], modulates the discrete charge packets, such that size of each charge packet is directly proportional to the instantaneous voltage applied to the input gate means [16]. A plurality of sequential charge output means [17], or injectors, in turn surround and are adjacent to the input signal gate means [16]. Each sequential charge output means [17] comprises a transfer gate [18] and a storage gate [20] for transferring and storing the charge packet modulated by the input gate means [16]. Once a charge packet is stored by storage gate [20], it is available for further processing as part of that particular data stream. By interleaving the data streams from all sequential charge output means [17], the original input signal may be reconstructed. The High Speed Charge-Coupled Sampler and Rate Reduction Circuit disclosed and claimed in this patent application provides an advanced, highly accurate and compact instrument for high frequency data acquisition and processing.
