Abstract: ABSTRACT OF THE DISCLOSURE           An oil pressure switch comprising a housing having an inlet end connectable to an oil pressure line to admit oil from the line within the housing.  A flexible membrane is secured in the housing and having opposed surfaces.  One of these opposed surfaces is in contact with the oil admitted to the housing whilst the other of the surfaces is in engagement with a spring biased electrical contact.  The spring biased electrical contact is in abutting engagement with a stationary electrical contact.  Connection means is provided for each of the electrical contacts.  The membrane is displaced by pressure in the oil line whereby the spring biased contact is caused to be displaced against its spring biased direction to cause dis-engagement with the stationary electrical contact.  The flexible membrane is a flat member of flexible impervious material having a peripheral ridge of larger thickness than the major portion of the flat member.  The ridge is clamped in a continuous cavity which is of larger cross-sectional area than the cross section of the ridge. The ridge is oval in cross-section with the long central axis of the oval extending transversely of the planar axis of the flat member.

Abstract: A METHOD AND DEVICE FOR THE NONDESTRUCTIVE TESTING    OF MATERIALS BY MEANS OF ULTRASONIC WAVES              Abstract of the Disclosure An incident beam of ultrasonic waves is directed onto the surface of a test piece for nondestructive testing and especially for measuring the case-hardening depth of steels.  The method consists in subjecting the beam to a uniform displacement at a constant angle of incidence, in detecting the ultrasonic waves back-scattered from the test piece, then in visualizing on a receiver the energies of the successive waves which are back-scattered during at least a predetermined fraction of the beam travel.

Abstract: ABSTRACT OF THE DISCLOSURE     A window shade roller including a main body, a motor shaft received within one end of the main body, and a tip shaft received within the other end of the main body.  The motor shaft is drivingly coupled to the main body so that the motor shaft can rotate the main body.          However, this driving connection does not prevent adjust-ment in the axial position of the motor shaft within the main body nor does it prevent complete withdrawal of the motor shaft from the main body.  The axial position of the tip shaft within the main body is also adjustable so that the overall length of the window shade roller can be ad-justed.  An insert within the main body limits the amount to which the tip shaft can be inserted within the main body.

Abstract: APPLICATION OF WILLIAM T. QUARTON         FOR      METHOD AND APPARATUS FOR MAKING HARD COPY  RECORDS OF CURVES INCLUDING CURVES WHICH ARE MATHEMATICALLY DESCRIBED AS MULTI-FUNCTIONS      FROM PERIODICALLY SAMPLED DATA POINTS       ABSTRACT OF THE DISCLOSURE A line scan cathode ray tube (CRT) recorder generates a hard copy record of a curve from stored data represent-ing the X-Y coordinates of a series of a sample points along the curve.  The curve may be described mathemati-cally by a multi-valued function.  One pass of the recording media past a linear sweeping CRT beam records the entire curve in a predetermined number of recording sweeps.  The distance (.DELTA. X and .DELTA. Y, respectively) between each and every Xn, Yn and the next successive stored sample point  Xn+1, Yn+1 is determined prior to each recording sweep of the beam and these distances, .DELTA. X and .DELTA. Y, are divided by a predetermined number to give a factor interpolating the distance between successively stored data points (Xn and Xn+1 and Yn and Yn+1). Each recording sweep of the beam represents a band (in the X-axis direction, for example) on the recording media of finite width extending from one recording sweep position up to, but not including, the next recording sweep position.  The X-Y coordinates of each sample point are successively incremented by the interpolative value   and  , respectively, where "n" equals the number of interpolative steps.  The Y-axis coordinate positions of the interpolative value    are stored correspond-ing to the interpolative X-axis coordinate    positions within the finite band to be recorded.  As the beam sweeps along a given X-axis position, it records a short line for each stored Y-axis position.    Subject matter disclosed in this application but not claimed herein is disclosed and claimed in my prior application bearing Serial No. 627,794, filed October 31, 1975.

Abstract: ABSTRACT OF THE DISCLOSURE          A hydrodynamic bearing capable of transmitting radial, thrust and moment loads between an inner load applying or supporting member rotatably connected to the bearing utilizes at least a pair of cylindrical groups of bearing pads disposed about a longitudinal axis of rotation, the pads having movable face portions with compound curved bearing surfaces symmetrically disposed about and along the longitudinal axis, the curved surfaces mating with similar curved bearing surfaces on a load applying or supporting member.  The face portions of the bearing pads are supported so that they are swingable about "swing points" located between the axis of rotation of the bearing and the face portions thereof under the combined influences of friction and load forces exerted thereagainst by the load applying or supporting member, so that through hydrodynamic action wedge-shaped lubricant films are generated between the relatively moving bearing surfaces to maintain the surfaces apart while the motion is occurring.  Radial,  thrust and moment loads between the load applying or supporting member and the bearing pads are all effectively transmitted by the bearing by reason of the particular relationship between the bearing surfaces, without adversely affecting the hydrodynamic action of the bearing.
