Abstract: Compounds of the formula  <IMAGE>  where X is OH, NH2, SH, OR or SR (where R is alkyl of 1 to 4 carbon atoms or benzyl), R1 is H or alkyl of 1 to 8 carbon atoms, R2 is H or methyl, Y is the salt of an amine of the formula  <IMAGE>  where R3 and R4 are lower alkyl, e.g., 1 to 4 carbon atoms and n is an integer of 2 to 4 with p-acetamidobenzoic acid and where z is a number from 0 to 10 are useful as immunomodulators, as antiviral agents and in specific cases have anti-leukemic activity. The compounds and compositions where z is 1 to 10 are novel per se. When R2 is H the presence of Y enhances the immunoregulatory activity and the antiviral activity. If X is the NH2 there is immunoinhibitory activity but no immunostimulatory (immunopotentiatory) activity.

Abstract: In order to perform automatic processing on radiographic images in mammography it is shown that it is possible to correct the undesirable effects of the linearity defect of the characteristic sensitivity curve of the radiographic film which has been used for this radiography by performing a statistical study of the noise in this image. It is shown that this statistical study (17) makes it possible to directly deduce the correction elements (15). The processing is then independent of any foreknowledge which might be available of the sensitivity of the film or of the conditions in which the exposures studied have been both acquired and then subsequently developed.

Abstract: A test system is associated with a chain of circuits on a circuit board for testing the interconnections linking the circuits in the chain as well as for testing the interconnections linking them to those on other boards.  The test system includes a controller for generating a test signal and for capturing a response signal generated by the associated chain of circuits in response to the test signal. The controller also generates a flow control signal which controls a network that routes the test signals from the controller, or from a first other test system, to the associated chain of circuits.  In accordance with the flow control signal, the network also serves to route the response signal from the associated chain of circuits to the controller or to a second other test system.  By selectively routing the test and response signals, the network in each test system allows individual testing of each associated chain of circuits or, alternatively, permits the chains of circuits on several boards to be effectively interconnected for testing.

Abstract: The present invention provides a slackless rotary drawbar assembly of simple yet rugged construction. The drawbar assembly preferably consists of five parts: a rotary drawbar, a rotary drawbar support housing, a bottom support casting, a rear support block, and a slack adjustment wedge. The rotary drawbar support housing is welded into the center sill of a railroad car and supports the rotary drawbar so as to permit unrestricted universal movement of the drawbar through the range of movement required under normal operating conditions. The rotary drawbar has an enlarged truncated convex spherical end portion which mates with concave surfaces formed in the support housing arid the bottom support casting. The bottom support casting is secured to the center sill and holds the drawbar in the support housing. The truncated convex spherical end portion also mates with a concave surface formed in the rear support block. A rear tapering surface of the rear support block is engaged by a mating gravity-activated wedge which is arranged to move vertically to compensate for wear and to maintain a slackless relationship of the parts that interconnect the drawbar with the train car.

Title: Training vehicle skid simulating mechanism
Inventor: SARUWATARI MINORU
IPC: G09B9/042
Filed: 1991-12-31
Granted: 2000-10-24
Abstract: An automotive training vehicle capable of providing controlled simulated skid conditions selectable in either right or left directions by a driving instructor accompanying a student driver. The vehicle has conventional front wheel steer and a pair of rear wheels mounted for simultaneous turn about parallel, substantially vertical axes. A switch which is located in a position accessible to the driving instructor activates a control system to energize a drive cylinder connected to the rear wheels for effecting turn of the rear wheels from a straight ahead position through an infinite number of positions to a maximum steer position in either direction from the straight ahead. The control system when in a non-activated condition places the drive cylinder in a hold position preventing turn of the rear wheels from the selected position. The severity of the simulated skid and its timing are thus fully within the control of the driving instructor.

Abstract: A spinning nozzle for dry spinning a spinning solution containing a metal compound and an organic polymer compound by a blowing method. In the spinning nozzle, an air nozzle 6 has a rectangular-prism-like slit which is formed by opposing inner surfaces, extending in parallel to each other, of the projecting portion, which are formed at the front side, of a pair of cover plates 1,1, each of the projecting portion having a knife edge portion at its free end. Spinning solution supplying nozzles are composed of a plurality of linear pipes and are arranged in the air nozzle 6 in such a manner that they are in parallel to the parallel surfaces of the cover plates and are projected from the edges of the parallel surfaces. Air fed through a gas feeding port 5 and blown out as an air stream from the air nozzle 6, and streams of the spinning solution extruded from the spinning solution supplying nozzles form parallel streams. Further, the air stream in parallel to the spinning solution streams is sufficiently rectified so that it becomes contact with the spinning solution.      Accordingly, an amount of air used can be greatly reduced and fibers having excellent quality can be produced.
