Abstract: A method of and an apparatus for rolling a rod as a starting material and producing a wire of 5mm or smaller diameter, the method and apparatus using a continuous rolling mill comprising a plurality of round-grooved four-roll stands arranged in tandem, wherein the grooved four-roll is displaced between adjacent rolling stands by 45 degrees relative to each other around the pass line and the center-to-center distance between adjacent rolling stands measured in the pass line direction is not greater than 50 times the diameter of the rod.  The front end portion of the rod is fed at slow speed into the continuous rolling mill, the front end portion being guided by a front pipe to the center of the round groove, and the front end portion is wound on a coiler.  After that, the rotation speed of the grooved rolls in each rolling stand is so set as to prevent slack in the rod passing through the continuous rolling mill, and the rod is rolled at high speed, without causing the rod to touch the leading pipe, to produce a wire.  Each of the rolling stands that constitute the continuous rolling mill is movable in a direction perpendicular to the pass line, each rolling stand being moved for connection to or disconnection from the driving source.

Patent CA-2078331-A1 (CA)
Title: System for diagnosing periodontal disease
Inventor: LOESCHE WALTER J
IPC: C12M1/34
Filed: 1991-03-15
Abstract: A colorimetric assay system for diagnosing periodontal disease utilizes a chromogenic test substance for measuring proteolytic activity in a specimen which may contain suspected periodontopathogenic bacteria. The colorimetric assay method of the present invention operates to detect the presence of proteolytic activity in a specimen of subgingival plaque, for example. A chromogenic test substance comprises a peptide substrate which is hydrolyzable by proteolytic enzymes in the plaque specimen to release the chromophore. Detection of a color change in the test substance indicates whether such proteolytic activity is present. In specific illustrative embodiment, the chromogenic test substance comprises N-benzoyl-DL-arginine-2-naphthylamide (BANA) or benzoyl-DL-arginine-p-nitroanilide (BAPNA). In the case of BANA, for example, the chromophore, .beta.-naphthylamide, is detected by the addition of a color developer, such as fast garnet. The development of a red-orange color is interpreted to indicate the presence of periodontal disease associated with anaerobic periodontopathogens, such as B.  gingivalis), T. denticola, and B. forsythus, and the development of a yellow color is interpreted to indicate the absence of periodontal disease.

Inventor: NITZBERG LEONARD R
IPC: F16L55/10
Filed: 1992-09-28
Abstract: Abstract:       A quickly-disconnecting coupling suitable for use in a fuel dispensing system reduces fluid pressure-generated axial separation forces on the coupling.  A first body member has one or more fluid passages therethrough in fluid communication with corresponding fluid passages through a second body member.  A detent is provided to couple said body members to each other in flow communication and to uncouple them when a force in excess of a predetermined level is exerted on the coupling.  The detent may be frangible or infrangible.  Means are provided to hold the first and second body members in axial juxtaposition with each other. Valving is provided for sealing fluid passages against loss of fluid when the detent releases the first and second body members front axial juxtaposition.  A hydraulic seal is so located as to prevent the pressurized liquid contained in the fluid passages from entering between the first and second body members at the axial interface thereof, thus limiting fluid pressure-generated damage to couplings, including effects of line shock.          A recouplable detent is also provided which has a spring with a contacting edge, a first annular recess in a first body member said first annular recess aligned with the second annular recess in a second body member, said second body having a camming surface, and, in the coupled position, said spring being located within the second annular recess with the contacting edge in contact with the camming surface.

Title: Selective radiation of pathological material
Inventor: CYRULNIK REUVEN A
IPC: H01J35/06
Filed: 1991-04-26
Abstract: Radiation of specific material within a subject (30) is accomplished by use of a beam (54) of x-radiation modulated at a microwave frequency. The beam (54) with its modulation is directed at the subject (30) wherein the material interacts with the beam (54) to extract a portion of the radiant energy carried by the beam (54).  In the interaction, an electric field at the modulating frequency appears at the material. By selecting the modulated frequency equal to a resonant interactive microwave frequency of the material, a photon at the microwave frequency is absorbed by the material to alter its physical and chemical properties.
