Title: Method for continuously and automatically monitoring the electrical efficiency and control consistency in a liquid crystal display unit
Inventor: PRINCIPE FRANCESCO
IPC: G09G3/00
Filed: 1988-07-21
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE:            A method for continuously and automatically monitoring the electrical efficiency and control consistency in a liquid crystal display unit consisting of determining the discharge or charge time of the capacitor having as its plates each segment and the backplane or return electrode of the display unit when the feed to said segment has been disconnected, said time being determined by a binary counter which commences at the moment of disconnection of said feed and stops when the capacitive discharge or charge voltage of said capacitor, converted into digital, differs from the segment feed wave.  The method also comprises monitoring the control consistency and the presence of the capacitive effect by direct comparison.

Title: Soft thermo-plastic polyurethane for blown film application
Inventor: HALL DALE R
IPC: C08L75/06
Filed: 1988-08-30
Granted: 1995-05-16
Abstract: Soft linear thermoplastic polyurethanes, which have low permanent set, high tear propagation resistance, and low blocking, and which are extrud-able by blown film techniques, are prepared by reacting one mole of a hydroxyl terminated poly-ester having a molecular weight from about 1800 to about 3600, from about 0.5 to about 2.0 moles of an aromatic glycol chain extender, and an organic diioscyanate in molar quantities substantially equal to the sum of the molar quantities of poly-ester and chain extender.  The polyester is a mixed polyester prepared by reacting at least two dif-ferent alaphatic glycols with one or more organic dicarboxcylic acids or at least one alaphatic glycol with two or more organic dicarboxcylic acids.  The aliphatic glycol may have from 2 to about 10 carbon atoms.  The organic dicarboxcylic acid may be either aliphatic or aromatic and may have from 2 to about 12 carbon atoms.  The pre-ferred chain extender is hydroquinone bis(beta-hydroxyethyl)ether.  Polymers of this invention are useful as elastic tapes, and in particular as leg bands in diapers and adult incon-tinence garments.  They may be used for other items of form-fitting apparel, such as ladies swim suits.

Abstract: ABSTRACT     In a dumb terminal to which an auxiliary device may be attached, improvements in display definition, in the transfer of data between a host computer and the terminal or an auxiliary device, and in character generation memory.  In the area of display definition, pages may be mapped onto the terminal's display memory and viewports may be mapped onto pages.  Page and viewport definition are independent of each other and settable modes permit a viewport to follow the active position.  In the area of transfer of data, the source of data for the host computer and the destination of data from the host computer may be specified independently.  Improvements in flow control ensure that the host computer can always change the destination of data and gain control of the terminal.  Improvements in access control ensure that neither the terminal nor the auxiliary device can monopolize transfer between it and the host.  Moreover, transfer can proceed transparently even when non-ASCII 8-bit codes or a 7-bit host-terminal link are involved.          Finally, a protocol permits one portion of character generation memory to be copied to another portion thereof.

Abstract: Method for the operation of a couple (MB3a, MB3b) of memory blocks working in parallel. At least one processor (BP, IOC) reads and writes information into the two blocks (MB3a, MB3b) in a normal operating time with read-write operation, the first block (MB3) respectively storing under one of its addresses the same information as the second block (MB3b) does under the same address. The first and second blocks (MB3a, MB3b) can be switched off in order to block access in a special operating time, at least during reading from said switched-off block (MB3b), in which case only the first block (MB3a) is operated completely in read-write operation. During the special operating time, an address generator (e.g. in IOC1) can systematically produce all the addresses of the blocks (MB3) sequentially, at least in stages. At the end of the special operating time, upon transition to the normal operating time, for the purpose of updating the information to be stored in the switched-off block (MB3b) during writing into the first block (MB3a), the same information is written into the second block under the same address. The address generator gradually supplies all the addresses of the pair (MB3) of blocks, for example during a pause in the read-write operation, the information read out in this process from the first block (MB3a) being written into the second block (MB3b) under the same address. Thereafter, both blocks (MB3) can once again be operated in parallel. <IMAGE>

Inventor: MCDANIEL MAX PAUL
IPC: C01B33/152
Filed: 1981-05-20
Abstract: A method comprising combining a silicate ester and water under hydrolysis conditions in the presence of a sufficient amount of solvent that the reaction mixture remains as a single phase, adding sufficient acid neutralizing agent to form a gel and separating solvent and water from the resulting silica. In a preferred embodiment, the ester and water are added to a very small amount of solvent, the addition of water being sufficiently slow that it is added at about the rate it is used up in the hydrolysis reaction. The resulting silica does not require the washing step to remove alkali metal ions since it is not made from sodium silicate, and it has large pore structure because it can be made in a relatively concentrated solution because of the use of only a minimum amount of solvent and also because the hydrolysis is carried out under conditions wherein only a single phase is produced. The resulting silica is suitable for chromatographic columns and fillers in rubber and plastics but is of primary utility as a base for a chromium oxide catalyst because of its simplicity in production and inherent large pore volume.
