Title: Method of depositing diamond-like carbon film onto a substrate having a low melting temperature
Inventor: CUMBO MICHAEL J
IPC: G02B1/10
Filed: 1991-01-03
Abstract: METHOD OF DEPOSITING DIAMOND-LIKE CARBON FILM ONTO A SUBSTRATE HAVING A LOW MELTING TEMPERATURE                 ABSTRACT OF THE INVENTION      A diamond-like carbon film is deposited on an insulating substrate using a solid carbon source evaporated by an electron beam so as to maintain the substrate temperature below about 150° C in a differentially evacuated chamber containing a selective etchant gas such as hydrogen.  In order to bombard the substrate with positively charged ions while preventing accumulation of a repulsive surface charge, a radio frequency (RF) electric field is applied to a rotating fixture holding the substrate.  The differentially evacuated chamber maintains the atmospheric pressure around the solid carbon source at one end of the chamber at a sufficiently low pressure to prevent loss of electron beam energy and thereby enable vaporization of the carbon while maintaining the substrate at the other end of the chamber at a higher pressure which enables the RF electric field to excite an ion gas plasma around the substrate and thereby facilitate deposition of the diamond-like carbon film.  In the preferred embodiment, the differentially evacuated chamber has a bypass manifold connected between the two ends of the chamber. A control system responding to pressure sensing apparatus inside the chamber governs the position of a butterfly valve in the bypass manifold to regulate the differential pressure in the chamber.  In order to keep the substrate temperature below about 150°, the rotating fixture holding the substrate is water-cooled.

Title: A process for large-scale production of antimicrobial peptide in high purity
Inventor: TOMITA MAMORU
IPC: A61P31/04
Filed: 1992-06-09
Abstract: Lactoferricin (Trade Mark), also called LFCIN (Trade Mark), a potent antimicrobial peptide, is produced by contacting an enzymatic hydrolysate of bovine lactoferrin or any mixture of peptides containing lactoferricin preferably with a butyl moiety-containing hydrophobic interaction chromatography medium, or alternatively with a carboxymethyl moiety-containing cation-exchange chromatography medium, rinsing the medium to remove unbound peptides, desorbing the lactoferricin solution at constant pH, and desalting the desorbed solution. The utility of the process is illustrated, for example, as follows. An enzymatic hydrolysate of bovine lactoferrin (600 g) was contacted with 3000 ml of BUTYL-TOYOPEARL 650 M, the medium was rinsed with water, and then with McIlvaine (citric acid-sodium phosphate) buffer at pH 7Ø, and lactoferricin was desorbed with Mcllvaine buffer at pH 5Ø The desorbed material was desalted by contacting it with BUTYL-TOYOPEARL 650 M, rinsing the medium with water to remove the buffer salts, and desorbing the lactoferricin with 10 mM HCl. A yield of 10.5 g of 99% purity was obtained. The product has applications as a safe and effective antimicrobial agent for use in oral hygiene products, cosmetics, clinical foods, etc.

Abstract: Apparatus for deheading and cleansing shrimp in a continuous-flow product transport system for more efficient storage or peeling.          The apparatus transports  food product having weakly  attached appendages,  such  as  crustaceans  and  especially  shrimp,  along conduits in a fluid medium at a flow rate as controlled by a food pump.  Upstream conduit defines a flow channel having a certain cross-sectional area; downstream conduit defines a flow channel having a cross-sectional area less than that of the upstream conduit.   The narrowing of the flow channel in an intermediate conduit-connecting region causes an increase in the speed of the product-laden fluid in that region.  The ratio of the downstream speed to the upstream speed is inversely proportional to the ratio of the cross-sectional area of the downstream channel to the upstream  channel.    The  abruptness  of  the  speed  increase  is determined by the nature of the intermediate region.  A relatively abrupt narrowing of the flow channel in the intermediate region causes an abrupt speed increase, which creates hydrodynamic forces that tend to detach,  in the case of shrimp,  heads from the desirable tail meat.  An abrupt speed increase of about four to one is preferable.   In the higher-speed downstream flow channel, further cleansing of the shrimp of sand, dirt, and visceral fluids occurs.  The tails and detached heads are strained from the dirty transport fluid prior to the segregation of tails and detached heads.  Detached heads are discarded, and cleansed, headless tails are made available for efficient storage or peeling.
