Title: Caustic-free sweetening of sour hydrocarbon streams
Inventor: BRICKER JEFFERY C
IPC: B01J31/02
Filed: 1990-04-23
Granted: 1997-06-24
Abstract: The present invention deals with a process for sweetening a sour hydrocarbon fraction containing mercaptans. The process involves contacting the hydrocarbon fraction with a catalytic composite in the presence of an oxidizing agent, ammonium hydroxide and a quaternary ammonium salt other than hydroxide. The instant process does not use any strong base nor any alkali hydroxides to sweeten the sour hydrocarbon fraction and thus obviates waste disposal problems.

Title: Pentapeptide antibiotics derived from dalbaheptides
Inventor: MALABARBA ADRIANO
IPC: A61P31/04
Filed: 1990-07-17
Granted: 2001-03-06
Abstract: Pentapeptide antibiotics of the formula (see formula I) wherein W, Z, X1, X2 and T represent the relative portions of an antibiotic of the dalbaheptide group (glycopeptide antibiotics), Y represents a carboxyacid group, a functional derivative of said carboxyacid group or a hydroxymethyl group. The invention includes the salts of the above represented pentapeptide antibiotics with acids or bases as well as their inner salts.        The compounds are obtained by reductive cleavage of the peptidic band between the second and the third aminoacid of the seven aminoacid chain of dalbaheptides (glycopeptide antibiotics). The inventions concerns also the reductive cleavage process which implies using an alkali metal borohydride as the reagent. The compounds show antibacterial activity against staphylococcal and streptococcal strains.

Title: Damped binding apparatus
Inventor: SCHENK RICHARD C
IPC: B42C1/12
Filed: 1990-07-23
Granted: 1997-01-14
Abstract: An apparatus which adhesively binds a set of sheets by applying a strip having an adhesive on one surface thereof to the spine of the set.  The strip is supported on a heated platen which softens the adhesive.  The spine of the set of copy sheets is pressed into the adhesive on the strip.  The depth of penetration of the spine into the adhesive is controlled so as to form a layer of adhesive between the spine and the strip having a predetermined thickness.  As the spine of the set of copy sheets is moved into contact with the adhesive on the strip, it is damped to absorb a substantial portion of the kinetic energy of the set of sheets to reduce the deflection and distortion of the set of sheets.

Granted: 1997-11-04
Abstract: A method of and an apparatus for inspecting a bottle or the like by which presence or absence of a defect, particularly of a check, can be determined with a high degree of accuracy.  Light is irradiated upon an inspection area of an object being rotated or moved, and reflected light is photographed by means of a two-dimensional camera which includes solid-state image pickup elements.  Picture element data for a first frame are fetched at a first point of time from the two-dimensional camera and stored into a memory, and then picture element data for a second frame are fetched at a second point of time after a fixed interval of time after the first point of time.  Then, differences of the picture element data for the second frame from the picture element data for the first frame from the memory are taken and binary digitized with reference to a predetermined brightness threshold level, and a number of those of the differences which have one of two binary values is counted.  The count number is compared with a predetermined number to determine presence or absence of a defect in the object for inspection.

Granted: 1998-11-10
Abstract: A protocol is defined for mixed data/voice/multimedia communications systems to transmit and receive high-priority, real-time traffic over low-speed digital communication links by embedding such high priority traffic in low priority, non-real-time traffic. High priority, real-time packets are thus transmitted without delay by preempting low-priority packets. Low priority, non real-time packets are held during preemption, and lowpriority transmission is automatically resumed after transmission of high priority packets has been completed. A protocol is defined for communications systems to exchangeinformation, at the time that a communication link is activated, defining their link capabilities for handling high priority, real-time packets and to agree on how this high priority traffic will be transmitted on the communication link.
