Title: Optical disk case assembly
Inventor: RAYNER ADRIEN P
IPC: G11B23/03
Filed: 1990-04-04
Abstract: ABSTRACT            OPTICAL DISK CASE ASSEMBLY      An optical disk case assembly comprises A-side and B-side case parts (10,11).  Each case part has a central opening (28) and a radially extending window (29).  Metal shutters (12) and (17) are mounted for sliding movement on the case parts (10,11).  A slide member (13) made from a plastics material is slidably mounted on the case part (10) and held in position by shutter (12).  A slide member made from a plastics material is also mounted on the case part (11) and held in position by shutter (17).  The slide member on the case part (11) engages the slide member (13) so that the two slide members together with shutters (12 and 17) move together. The slide member (13) has an operating tab (72) which engages a projection in a cartridge compartment so that the shutters (12 and 17) are cuased to open during insertion of the case assembly into such a compartment).  The case part (10) is also provided with a locking lever (15).  The components associated respectively with the case parts (10,11) may be secured in position prior to inserting an optical disk. Consequently, in order to insert an optical disk, it is only necessary to place the optical disk in position and secure the two case parts (10,11) together with self-tapping screws (39).

Title: Hot melt inks for colored ink jet images
Inventor: CREAGH LINDA T
IPC: C09D11/00
Filed: 1991-01-22
Abstract: Hot Melt Inks for Colored Ink Jet Images Abstract In the particular embodiments described in the specification, hot melt inks (110,120) for colored ink jet images are described which have relatively narrow melting ranges while at the same time inhibiting crys-tallinity upon quenching to reduce attenuation of transmitted light.  In addition, the inks (110,120) intended for application to the same substrate have matched surface tensions at the temperature at which they are maintained above their melting point on the substrate to avoid mingling of different inks at their interfaces.  Furthermore, the inks have an elongation of at least 3%, and preferably about 5-10%, so as to avoid delamination from a transparent substrate de-spite relatively low adhesive strength of the ink to the substrate.

Filed: 1991-03-27
Abstract: A spring powered roll type fiberglass window screen has side edges received in guide channels in which locking bars are pivotally and slidably received.  In closing the screen, the locking bars are longitudinally slidable by a screen actuator which in turn causes the locking bars to be pivoted into engagement with the screen by action of a guide actuator tab engaging a cam surface on the locking bar.  In opening the screen, the screen actuator moves the locking bar upwardly until it is pivoted out of engagement therewith by a guide cam surface on the guide channel whereupon the screen is free to move to a fully raised position, leaving behind the locking bar.

Title: Bleach-fix regeneration kit and use thereof in photographic processing
Inventor: LONG JOHN J
IPC: G03C7/44
Filed: 1990-01-29
Abstract: A three-part bleach-fix regeneration kit is utilized to restore the capability of a spent bleach-fix solution to function as a working solution in photographic processing. The first part, which is an aqueous alkaline solution containing a buffering agent and an aminopolycarboxylic acid, is added to the spent bleach-fix solution prior to electrolytic recovery of silver therefrom. The second and third parts, which are aqueous acidic solutions containing, respectively, an iron salt and a thiosulfate fixing agent, are added after electrolytic recovery of silver. The first part functions to increase the pH of the spent bleach-fix solution to a level at which electrolytic silver recovery is optimized, while the second and third parts function to lower the pH to an optimum level for use in photographic processing. In addition to providing the necessary pH changes, addition of the three parts in this manner restores all necessary components to their proper concentration. Reaction of the aminopolycarboxylic acid and the iron salt brings about in situ generation of the complex which functions as the bleaching agent.
