Title: Laminated printing plate apparatus and method
Inventor: DALTON EDWARD L JR
IPC: B41C1/00
Filed: 1987-06-18
Granted: 1990-11-20
Abstract: LAMINATED PRINTING PLATE   APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE            A photoengravable,  laminated printing plate comprises a sheet  of  tempered,  cold rolled steel in the order  of 0.005 to 0.015 inch thick,  a sheet of magnesium in  the order  of 0.020 to 0.030 inch thick,  and an  interposed layer of adhesive which consists of an homogeneous layer of  bubble-free  cured  epoxy.   The  thickness  of  the magnesium  is  at least as great as the desired  relief, when  photoengraved.   The  adhesive  is  free  of  non-compressible materials. The plate is produced in a press by  mating  the  sheets  with  the  adhesive   uniformly dispersed between them, and removing the assembled plate from the press after the adhesive has cured.

Title: Multi-cpu interlock
Inventor: COLLINS RICHARD M
IPC: H04L29/00
Filed: 1987-07-27
Granted: 1991-09-03
Abstract: ABSTRACT     A multi-CPU  interlock mechanism  is  disclosed which permits the simultaneous servicing of two or more CPUs when an  input/output  (I/O)  order  is  issued from  each  of  these CPUs. When two CPUs issue simultaneous input/output orders which  typically  have  function code  pairs,  such  as  for example,  FC=09/OD,  each  of  these  orders  being  individual orders  but  with  the  second  OD  order  having  no  source identifier,  the invention permits both of these CPUs to be serviced by causing a negative acknowledge (NAK) signal to be issued to the second CPU until  the first IOLD orders have been  serviced,  thus  preventing  ambiguous  cycles  and  an inability of the CPUs to be serviced.

Title: Storage rack for magnetic tape cartridges
Inventor: HATCHER DAVID O
IPC: G11B23/023
Filed: 1987-11-17
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE A storage rack for magnetic tape cartridges includes a plurality of shelves for supporting a plurality of cartridges in an upstanding side-by-side relationship and side supports for supporting the shelves in a spaced superposed relationship.  Each shelf includes a planar platform for cartridges operatively positioned thereon and a planar back for the shelf.  The planar platform defines a substantially linear forward edge opposite the back of the shelf which underlies a tape cartridge operatively positioned upon the shelf and supports the tape cartridge so that the overlying cartridge edge defines an angle within the range of about ten to twenty degrees with the horizontal.  The platform of one shelf is spaced above the platform of the underlying shelf a distance which is substantially no greater than the vertical height of a cartridge when positioned upon the underlying shelf plus an amount providing finger clearance between the underside of the platform of the one shelf and the upper edge of a cartridge when positioned upon the underlying shelf so that an index finger of one hand can be positioned atop a cartridge stored upon the underlying shelf at a location on the cartridge adjacent the upper forward corner of the cartridge and the cartridge pivoted forwardly with the index finger relative to the underlying shelf about the corresponding forward edge from a stored condition to a forwardly-tilted condition in relationship to adjacent cartridges so that the opposite sides of the cartridge can be grasped between the thumb and remaining fingers of the one hand for purposes of withdrawing the cartridge from the underlying shelf.

Title: Pulp souring process enhancing conservation of specific bleaching agent residuals
Inventor: LACHAPELLE RAYMOND C
IPC: D21C9/14
Filed: 1988-01-21
Granted: 1991-09-17
Abstract: ABSTRACT OF THE DISCLOSURE     There is disclosed a process for souring chemical or mechanical cellulosic pulp using carbon dioxide to obtain proper acidification of the pulp slurry. The souring is performed after a single or a multistage bleaching sequence ending with sodium hypochlorite, calcium hypochlorite or hydrogen peroxide or the like in a common process for the preparation of paper pulp. The use of CO2 permits bleaching to continue because CO2 does not destroy the bleaching residuals remaining from the single or last bleaching stages.

Abstract: Abstract of the Disclosure In a method for Liquid Phase Epitaxy (LPE) of semi-insulating InP, a solution of P, Ti and a p-type dopant in molten In is cooled in a non-oxidizing ambient at a surface of a substrate to grow an epitaxial layer of doped InP on the surface.  The concentration of p-type dopant in the solution is such as to provide a concentration of p-type dopant in the grown epitaxial layer greater than the aggregate concentration of any residual contaminants in the grown epitaxial layer, and the concentration of Ti in the solution is such as to provide a concentration of Ti in the grown epitaxial layer greater than the concentration of p-type dopant in the grown epitaxial layer.  The required melt concentrations are determined empirically.  The method can be performed at temperatures below 650 degrees Celsius and is particularly suited to the LPE growth of semi-insulating InP to isolate InP-InGaAsP buried heterostructure lasers.                             - i -

Title: Apparatus for keeping a rain water well unfrozen
Inventor: ARMANTO HEIKKI
IPC: E03F5/04
Filed: 1988-09-13
Granted: 1992-05-05
Abstract: Abstract The invention relates to an apparatus for keeping a rain water well unfrozen.  The apparatus comprises a cover (12), walls (13) and an outlet (15), which de-fines an air space (16) of the well above the outlet and a water space (17) of the well below the outlet. According to the present practice, the whole surface area of the water in a rain water well is in contact with open air, which results in that the well freezes relatively easily under the joint influence of wind and frost. This problem is solved according to the in-vention in such a way that the apparatus comprises a funnel (1) positioned under the cover (12) of the well and a flow tube (5), the cross section of which is substantially smaller than the diameter of the well and which tube extends from the lower part of the fun-nel (1) under the water surface of the well.

Abstract: ABSTRACT OF THE DISCLOSURE         A potential of a reference potential measure section is set to a desired value of a potential of a drum surface (charge receptive surface) such that a potential of the reference potential measure section and a potential of the charge receptive surface are detected by a surface potential detect device during a rotation of the drum to obtain a difference between the values of the measured potential, so that an operation of a charger is controlled to be reduced to zero, thereby changing the potential of the charge receptive surface.  This enables the surface potential to be precisely controlled without necessitating a frequent calibration of the surface potential detect device.  In addition, the potential of the reference potential measure section is appropriately set depending on a develop condition so as to prevent a toner, when the portion passes a developer at a position over a circum-ferential area of the drum, from being fixed thereonto.          Moreover, a potential of the reference potential detect section and a potential of the charge receptive surface are detected by use of the surface potential detect device so as to examine a difference therebetween and a distribu-tion thereof, which enables a change as well as an irregular variation of the potential due to deterioration of the charge receptive surface to be analyzed.  based on the analysis, it is possible to detect the deterioration of the photoconductive body as the charge receptive surface so as to evaluate the life thereof.  Furthermore, when an information processing system is configured by combining a computer with an electrostatic recording apparatus according to the present invention, there can be provided a picture quality control system effecting a precise control depending on a characteristic of the photoconductive body.
