Abstract: RAILROAD CAR WHEEL BEARING HEAT    SIGNAL PROCESSING CIRCUIT            ABSTRACT OF THE DISCLOSURE           An improved method and circuit is provided for processing waveforms from a railway car heat signal to eliminate spurious signals and to differentiate between roller bearings and friction bearings in a railroad hot box detector system.  The waveforms generated by passing bearings are discretely sampled and spurious signals are eliminated by considering only those signals that fall within the crossing points of a threshold value.  Discrimination between roller bearings and friction bearings is obtained by determining the ratio of the sum of the discrete values of the amplitude of the waveform within a first set of samples between the crossing points to the sum of the discrete values of the amplitude of the waveform within a second set of samples between the crossing points.

The auto focusing system as herein described provides a zoom lens system in which the zoom lens is adjustable to change from a normal focal length to a longer focal length and in which a subject may be brought into focus by axial movement of at least one lens component of the zoom lens system.  The zoom lens is located in front of a screen in the camera and the zoom lens system is arranged to focus the viewing subject thereon.  An auto focus system herein described comprises a pick-up lens including a zoom system, a distance measuring light source and a distance measuring light receiving portion, said pick-up lens having a focus adjusting mechanism, the distance measuring light source being illuminated, and a detecting device for detecting the angle of the reflected light beam emitted from said light source and reflected by the subject, the focus adjusting mechanism being driven in accordance with the detected distance determined by the measurement output and either of the distance measurements.

Abstract: - 14 -                   Case 4391 ABSTRACT OF THE DISCLOSURE       A co-ordinate measuring system for determining the relative measurements of an object is disclosed.  The system utilizes a probe which has a plurality of faces which are interconnected so as to form two parallel "X" co-ordinate probe surfaces (12) and two parallel "Y" co-ordinate probe surfaces (14).  At the instant the probe contacts a surface on the object being measured, an electrical circuit is completed through the probe to ground potential via the object, causing the measurement to be displayed on a visual display device (20 or 22). In this manner, measurements along the "X" and "Y" co-ordinates can be made and recorded at the instant the probe contacts the respective surfaces.  An automatic unlatching feature is provided wherein the probe must be a predetermined distance from both the "X" and "Y" surfaces before the system automatically resets.

The flattened tube then travels through a metering device made up of wipers in the form of doctor blades or rollers, which retain the major quantity of the coating liquid which is present on the inside surface of the tubing so that a thin, uniform film of the coating liquid is formed.  The tubing is thereafter dried to remove the volatile constituents of the coating llquid, and is subsquently wound up.

Abstract: A method at delignification of cellulose pulp A B S T R A C T        When using oxygen gas and alkali to delignify and bleach chemical cellulose pulp, it is not possible to remove more than approximately half the amount of lignin remaining in the cellulose pulp after the cook, due to the risk of intensive and uncontrollable de-gradation of the carbohydrates in the cellulose pulp. By means of the invention it is now possible to remove three quarters of the amount of residual lignin while maintaining good pulp qualities, and the invention relates to a method for delignifying chemical cellulose pulp, in which the pulp is brought into contact in an activating stage with a gas phase containing NO2, and oxygen gas is supplied to the activating stage so that the intermediary nitric oxide formed is utilized for activating the pulp, and the activating stage is carried out under drastic conditions. The method is characterized in that the pulp is then subjected to an oxygen gas-alkali-treatment process in a pulp-water mixture, the partial pressure of the oxygen gas during the oxygen gas-alkali-treatment process being held at 0.005-0.18 MPa; and in that the partial pressure of the oxygen gas does not fall beneath the lower partial pressure limit during any part of the treatment process.

Abstract: MAGNETICALLY SENSITIVE TRANSISTORS UTILIZING   LORENTZ FIELD POTENTIAL MODULATION OF            CARRIER INJECTION                           Abstract Magnetically sensitive transistors utilizing a newly discovered transduction mechanism are described. The transduction mechanism is Lorentz field potential modulation of carrier injection at the emitter-base junction.  Either avalanching or non-avalanching collectors are utilized in a structure having a single emitter and at least one but preferably two collectors.  The emitter-base junction is forward biased to inject carriers and the collector-base junctions are reverse biased to collect carriers. Carrier injection is modulated by a Lorentz field. The Lorentz field is produced across the injecting surface of the emitter by interaction between the moving injected carriers by intersection with a magnetic field according to the Lorentz principle. The Lorentz field biases a portion of the emissive surface to inject more heavily and biases the re-maining portion to inject less heavily.  The carriers streaming toward the separate collectors are thus more heavily concentrated for one collector than the other.  For maximum sensitivity, it is important to configure the positions and dimensions of the emitter and collector or collectors such that the maximum Lorentz potential, and hence the maximum biasing modulation, is applied to the predominant injection area of the emitter.  Since the maximum Lorentz potential can be developed across the longest physical dimension of the emitter, the preferred arrangement of emitter and collector is with the collector located to one side or the other (or both sides where two collectors are employed) of an imaginary plane bisecting the maximum Lorentz contour.  The Lorentz potential can be developed on one geometrical axis and electrically coupled to a primary injection area elsewhere or on another axis for maximum effect.
