Title: Method for manufacturing glass bottles
Inventor: NAKAGAWA MANABU
IPC: B65G47/82
Filed: 1993-06-15
Granted: 2000-02-22
Abstract: The problem of unevenness of bottle temperatures at the entry of slow annealing furnace due to the variation of time periods necessary for respective bottles discharged from an IS bottle manufacturing machine to reach the annealing furnace has been solved by an equalization of said time periods. For this purpose, the bottle discharging order from the IS bottle manufacturing machine is controlled and use is made of two conveyors having different running speeds and/or direction of running. As a result, a precise temperature control in the Hot-End-Coating apparatus provided upstream from the annealing furnace can be carried out owing to the equalized temperatures of bottles entering into the annealing furnace.

Title: Telecontrollable communication system having a remote transmission module
Inventor: KLEIN JOSEF
IPC: H04Q11/04
Filed: 1994-06-24
Granted: 2002-02-05
Abstract: A communication system equipped with a central computer means is connected to a service central via a communication network, for example, a telephone network of ISDN network, for telecontrol thereof. For the information exchange between the service central and the communication system, a teletransmission module is arranged in the latter, this telecommunication module being connected to the central computer means via a computer/bus interface and via a PCM-oriented system/bus interface. An information transmission via different communication networks, preferably via the telephone network or via the ISDN network, can be set using the teletransmission module. Due to the central arrangement of the teletransmission module with different information transmission procedures for different communication networks and due to the control of the call setup and cleardown for different communication networks by the central computer means that is possible as a result thereof, externally connectable transmission equipment (for example, modems) including a call setup and cleardown controller provided for this purpose can be eliminated.

Title: Apparatus and method of treating process condensate
Inventor: HOLIDAY ALLAN D
IPC: B01D3/38
Filed: 1994-07-12
Granted: 2000-01-04
Abstract: An apparatus and method for treating chemical production plant process condensate such that a contaminant-rich stream and a relatively pure aqueous stream is separately recoverable from the condensate, wherein the contaminants are substantially removed from the condensate by steam stripping and subsequent rectification in a relatively low pressure stripping/rectification tower. The tower overhead is then condensed with a portion of the condensed overhead being returned to the tap of the rectification section of the tower as reflux and the balance being withdrawn as a concentrated stream for reuse in the plant. In a second embodiment, separate stripping and rectification towers operate in series whereby the overhead of the stripping tower is delivered to the lower section of the rectification tower and the rectification bottoms are returned to the top of the stripping tower. The overhead from the rectification tower is then condensed with a portion returned at its top for reflux and the remainder being withdrawn as a highly concentrated stream for recycling to the ammonia plant. The mass flow to the ammonia plant is low enough because of high concentration that ammonia plant modifications are not needed nor is there significant thermal impact. The apparatus may be used in conjunction with existing low pressure equipment, avoiding costly major modifications.

Title: Methods and compositions for gene, tumor, and viral infection therapy, and prevention of programmed cell death (apoptosis)
Inventor: ROIZMAN BERNARD
IPC: A61K48/00
Filed: 1993-02-26
Granted: 2003-12-30
Abstract: The present invention relates to methods of treatment of programmed cell death (apoptosis) through the use of the HSV-1 gene  .gamma.1 34.5 or the product of its expression, ICP34.5. The gene and its expression have been demonstrated to be required for HSV-1 neurovirulence, and in particular, to act as an inhibitor of neuronal programmed cell death which allows for viral replication. Use of the gene therapy, or the protein itself, can be expected to result in inhibition of programmed cell death in various neurodegenerative diseases. This invention also relates to novel vectors for gene therapy, including modified herpes virus. Methods are presented for conducting assays for substances capable of mimicing, potentiating or inhibiting the expression of .gamma.1 34.5 or the activity of ICP34.5. Also, methods are disclosed for the treatment of tumorogenic diseases, including cancer, and for treatment of herpes and other viral infections using inhibitors of .gamma.1 34.5 expression or ICP34.5 activity.

Title: Anti-drainback/pressure-relieved filter cartridges for lubricating oil
Inventor: COVINGTON EDWARD A
IPC: B01D27/10
Filed: 1995-02-22
Granted: 2004-08-03
Abstract: Filter cartridges having annular filter elements retained within housings include a cylindrical valve support on which an annular valve is mounted. The annular valve has a valve skirt and a valve sleeve. During normal operation, the valve skirt deflects, allowing lubricating oil to flow to and through the filter element. When the filter element clogs, the valve sleeve deflects, uncovering openings through the valve support which the valve sleeve normally blocks. Lubricating oil then flows through the openings in the valve support bypassing the clogged filter. In accordance with one embodiment of the filter cartridge, the filter element, valve and valve support are held in axial abutment within the filter housing by a coil spring.    In accordance with preferred embodiment of the filter cartridge, the filter element valve and valve support are retained in the filter housing by adhesive.

Abstract: Oxygenated acetyl compounds ethylidene diacetate, acetic acid, acetic anhydride, acetaldehyde, and methyl acetate are produced directly from synthesis gas and dimethyl ether in a catalyzed liquid phase reaction system.  The inclusion of carbon dioxide in the synthesis gas in selected amounts increases the overall yield of oxygenated acetyl compounds from the reactant dimethyl ether.  When methanol is included in the reactor feed, the addition of carbon dioxide significantly improves the molar selectivity to ethylidene diacetate.

Title: Variable security level encryption
Inventor: ALANARA SEPPO
IPC: H04L9/06
Filed: 1996-02-02
Granted: 2005-06-28
Abstract: A method and apparatus for digital cellular telephone encryption includes a switch when a choice between compatibility security and a higher security is required.      Plaintext is converted into ciphertext using a three-stage transformation process. In a first stage, the plaintext is transformed using a secret key to control encrypting by an invertible transformation process. In a second stage, the output of the first stage is transformed by an involutory transformation, which is unkeyed when the compatibility switch is in a compatibility setting and keyed when the compatibility switch is in a secure setting. In a third stage, the output of the second stage is transformed by the inverse of the transformation performed in the first stage. The compatibility switch is used to toggle between compatibility with a less secure encryption standard and a key-based secure encryption.
