Title: Adhesion of latex coatings to polymeric surfaces
Inventor: KAN CHARLES S
IPC: C08J7/043
Filed: 1986-09-18
Granted: 1991-12-17
Abstract: ABSTRACT             A process for adhering a latex film to a polymeric substrate through the formation of covalent bonds at the interface of the polymeric substrate and the latex film.  The covalent bonds are formed through the reaction of a cyclic imino ether group, 2-alkenyl--2-oxazoline, and a coreactive group, active hydrogen, epoxy or anhydride group, one of which is present in the polymeric substrate and the other of which is present in the latex.  A product prepared from the improved method of adhering a latex film to a polymeric substrate is also included.

Abstract: SUMMARY          A printing machine (1) with at least one printing unit (4-7) is proposed, featuring a number of sensors for monitoring the printing procedure and a number of control elements for setting, for example, the ink profile, the fluid profile, the paper feed and other similar functions. The entire processing of the sensor signals, their interlinking and the output of control signals, as well as the output of display signals takes place in an overall electronic control (11) which is linked via data lines (21,22) with the printing machine, or the sensors and the control elements in the printing machine (1).          Furthermore, assigned to the overall electronic control circuitry (11) are measuring devices such as a printing plate reader (12) or a quality monitor (13), whereby the measured signals are correspondingly processed also to facilitate setting of the printing machine. monitoring of the printing process and any interventions in the control of the printing machine which may be necessary are facilitated by a control desk (15) which is assigned to the overall electronic control circuitry (11) via a data line (26). The printing machine itself contains no additional electronic or electrical control devices but, apart from the sensors and control elements, only the displays and control facilities necessary for monitoring the printing procedure.

Abstract: ABSTRACT OF THE DISCLOSURE         Leu-3- cells surviving infection with the AIDS retrovirus can be induced with IUdR to express infectious virus.   A  cellular  clone  (8E5),  isolated  by  limiting dilution of a mass culture of survivor cells, was found to contain a single,  integrated,  defective provirus that was constitutively expressed.  Although IUdR treatment of 8E5 cells failed to induce infectious virus,  cocultiva-tion  with  Leu-3+  cells generated  the  characteristic syncytia  associated  with  acute AIDS  retrovirus  infec-tion.  The single integrated copy of proviral DNA directs the  synthesis  of  all  major  viral  structural  proteins except p64 and p34 as monitored by immunoblotting.  Diag-nostic reagents and kits in accordance with the present invention are also described.

Title: Method of and apparatus for supplying coating agent to coating robot
Inventor: NOZAKI HIROYOSHI
IPC: B05C11/10
Filed: 1987-04-23
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE              A supply line for supplying a sealant from a sealant supply source to a sealing robot has pressure sensors and is coupled to relief valves through branch lines.  If the pressure in the supply line excessively rises or drops, then the relief valves are opened to release the pressure from the supply line and the supply pump is inactivated.  The pipes, devices, and pump on the supply line are therefore protected from damage.  The sealing robot has an sealant applicator gun movable with respect to an article to which the sealant is to be applied by the sealing robot.  A pump driving device is controlled to vary the rate at which the sealant is discharged from the pump as a function of the speed of relative movement of the sealant applicator gun with respect to the article.

Title: Automatic focusing circuit
Inventor: MURASHIMA HIROTSUGU
IPC: H04N5/232
Filed: 1987-06-09
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE    An automatic focusing circuit in a video camera separates a high frequency component from the video signal obtained in an image sensing circuit 4 for every field.          After the separated high frequency component is integrated in an integration circuit 10, the result is converted into a digital value by an A/D converter 11 and is applied to a holding circuit 12 as a focus evaluating value.  The holding circuit 12, which comprises first to fifth memories coupled in series, always holds the newest successive five focus evaluating values.  The largest focus evaluating value is detected by the maximum value detecting circuit 18 for every field and is applied to a memory 19.  The maximum value is compared with the maximum value one field before held in a memory 20 in a comparator circuit 21.  If the newest maximum value in the memory 19 is decreased, a focusing motor control circuit 22 inverts the rotational direction of the focusing motor 3.  Thus, since the focusing ring is slightly vibrated in the maximal point of the maximum value of the detected focus evaluating value, a focusing lens can be held in the in-focus position.

Title: Process and apparatus for manufacturing a high strength rail
Inventor: ECONOMOPOULOS MARIOS
IPC: C21D9/04
Filed: 1987-07-09
Granted: 1992-09-22
Abstract: ABSTRACT OF THE DISCLOSURE          Starting from a temperature at or above the A3 transformation point of the steel of the rail, the head of the rail is cooled to a temperature not lower than the Ms point at a rate lower than the critical quenching rate so that the head acquires a fine perlitic structure.  Simultaneously the web is superficially cooled to the Ms point or below, at a rate greater than the head, so as to obtain a surface layer of martensite and/or bainite, and the surface cooling is controlled so that, at the end of controlled cooling, internal portions of the web not transformed to martensite and/or bainite retain sufficient heat to temper the surface layer during subsequent cooling to ambient temperature.          At the same time the flange of the rail is cooled at a rate ensuring straightness of the rail.

Abstract: ABSTRACT OF THE DISCLOSURE      A mechanism for determining when the contents of a block in a cache memory have been rendered stale by DMA activity external to a processor and for marking the block stale in response to a positive determination.  The commanding unit in the DMA transfer, prior to transmitting an address, asserts a cache control signal which conditions the processor to receive the address and determine whether there is a correpondence to the contents of the cache.  If there is a correspondence, the processor marks the contents of that cache location for which there is a correspondence stale.

Abstract: ABSTRACT: "Optically readable record carrier for recording information, method and apparatus for manufacturing such a record carrier, apparatus for recording information on such a record carrier, and apparatus for reading information recorded on such a record carrier."         A record carrier (40) comprises a radiation-sensitive layer (43) upon a disc-shaped substrate (42) and is provided with an information-recording area arranged in accordance with a spiral-shaped or concentric pattern of preformed tracks (41). The track exhibits a track modulation in the form of a radial wobble whose frequency is modulated with a position-information signal (Ip). Further, an apparatus (1) is disclosed fox forming the track pattern during the manufacture of the record carrier (40). When an information signal (Vi) is recorded on the record carrier (40) and the recorded signal is read an FM demodulation device (60) recovers the position-information signal Ip from the variations in the scanning beam (54, 54a) produced by the track modulation. Moreover, a clock signal for the purpose of scanning-velocity control is recovered from these variations in the scanning beam. (Figure 4.)
