Abstract: A circuit for detecting and verifying a presence of a terminating device for a high speed data transmission line.  The circuit contains a first cable detector which generates a first signal if a first cable is present.  A second cable detector generates a second signal if a second cable is present.  The terminating device is contained in a plurality of resistor packs, each of the which contains an extra resistor.  A terminating device detector senses the extra resistor presence, thereby detecting the presence of the resistor packs.  The terminating device detector generates an ALL-EQUIPPED signal and a NON-EQUIPPED signal, the ALL-EQUIPPED signal is generated when all of the plurality of resistor packs are present, the NON-EQUIPPED signal is generated when all of the plurality of resistor packs are absent. Finally, a verifier circuit receives the first signal, the second signal, the ALL-EQUIPPED signal and the NON-EQUIPPED signal. The verifier circuit verifies that if the ALL-EQUIPPED signal is present then only one of the first signal or the second signal is present, or, if the NON-EQUIPPED signal is present both the first signal and the second signal are present.

Title: Evaluative means for detecting inflammatory reactivity and for predicting response to stress
Inventor: STERNBERG ESTHER M
IPC: A61K38/095
Filed: 1990-09-25
Abstract: The present invention relates to a diagnostic test for testing susceptibility of individuals to inflammatory diseases such as rheumatoid arthritis and to means to evaluate potential treatment of arthritis with therapeutic agents directed at the central nervous system (CNS), designed to by-pass the CNS defect. The invention also provides means for evaluating and predicting response to stress in individuals. A counter-regulatory feedback loop exists between the immune and central nervous systems, in which the immune or pro-inflammatory mediators stimulate corticotropin-releasing hormone (CRH) activation of the hypothalamic-pituitary-adrenal (HPA) axis hormonal cascade. The resultant increase in plasma glucocorticoids serves to restrain and limit the intensity of the inflammatory-immune response, through the potent immunosuppressive/anti-inflammatory actions of the glucocorticoids.

Abstract: The problem of recycling scrap radial tires is addressed by providing many uses for a laminate made by bonding two or more belt sections of a radial tire, the sidewalls of which have been cut away, the tire then cut open, and de-treaded. The result is a multi-ply structure (11, 13) which is sensibly rigid in all three directions because each belt ply in a belt is reinforced with cords (12, 14) at an angle, the cord angle in one belt ply being opposed to the angle in the other. A slat, bar, or beam, formed with plural belts is essentially rigid in a direction at right angles to its longitudinal axis, because for bending to occur, one belt must be in tension and the other in compression. Neither condition is favored because of the opposed cord angles and belt geometry.  Though essentially rigid because of the cord geometry, the amount of rubber (16) in the laminate allows it to be deformable relative to wood or steel having the same thickness. The result is a laminate which has anisotropic properties but may also be used to absorb impact. Belts reinforced with steel wire cords are preferred.  Various configurations, such as arcuate slats, bars or beams may be formed, as well as mats and annular bodies.

Title: Oxy-fuel cutting tip having swaged gas outlet passages
Inventor: GOULET RICHARD
IPC: F23D14/42
Filed: 1992-08-28
Abstract: ABSTRACT OF THE DISCLOSURE    A multi-part oxy-fuel cutting tip has mixture outlet passages formed by swaging the tip skirt to form grooves.  The grooves then cooperate with the tip core to form the outlet passages when the skirt is placed over the lip core.          Oppositely directed circumferential inlet passages for the preheat oxygen and fuel promote rapid mixing while producing a non-rotating mixture flow.  In addition, the sectional areas of the outlet passages decrease in the flow direction.  These features promote the rapid creation of a laminar mixture flow.
Patent CA-2077818-A1 (CA)
Inventor: CORONA STEPHEN C
IPC: H04N1/29
Filed: 1992-09-09
Abstract: An image bar recording system, which, in a preferred embodiment, utilizes a plurality of LED image bars to provide a plurality of latent images which may subsequently be developed in different colors.     The print bars are initially aligned so that each color image is precisely registered at the same relative position along the exposed area of a photoreceptor belt. The alignment is accomplished by adding non-image fiduciary pixels to the ends of each print bar and by forming a pair of opposed alignment apertures in the surface of the belt. Y-axis alignment of the print bars is accomplished by detecting edge locations of a first pixel and using this location to select a centrally located fiduciary pixel. The X-axis alignment is then obtained by rotating the print bar to bring a second selected image pixel into alignment as sensed through a second aperture.      Once the initial X and Y-axis alignments are complete, subsequent alignment is maintained through subsequent passes by checking the positions of the previously identified pixels as they advance past additional lead edge apertures formed in the process direction along the belt surface.

Title: Spraying apparatus
Inventor: CZECH MANUEL
IPC: B65D83/58
Filed: 1992-10-02
Abstract: Abstract In conventional spraying apparatus, material disposed within a material container is kept by means of propellants at an increased pressure with respect to the ambient pressure. The material to be sprayed is dispensed with the aid of a dispensing valve to be operated in a manual way. To avoid the use of propellants which are harmful to the environment, the present invention suggests a spraying apparatus comprising a supply chamber which contains the material to be sprayed and includes a pressure chamber of variable volume. This pressure chamber of variable volume is connected to an actuating means which is provided for increasing the volume of the pressure chamber and thus for sucking material from the supply chamber into the pressure chamber. Since the material within the pressure chamber is kept under pressure by a pressurizing means, a nonreturn valve is disposed in the suction conduit leading to the supply chamber. Material can be sprayed with the aid of said spraying apparatus without any harmful effects on the environment, the use of conventional spraying heads being here possible.
