Abstract: AIR DEFLECTOR FOR TRACTOR-TRAILER VEHICLE                 Abstract of the Disclosure An air deflector, which is adapted to be mounted on the roof of a cab of a tractor pulling a trailer and has a frontwardly facing totally curved air deflecting surface that is symmetrical about a vertical center plane and is forwardly convex in all horizontal and vertical cross-sectional planes, is disclosed.          To define the deflecting surface, the deflector has a central portion and a pair of symmetrical rearwardly turned wing portions at the opposite sides of the central portion and includes a top edge of substantially circular curvature and a base edge of substantially elliptical curvature. The deflector is installed for angular adjustment about a horizontal axis to a number of different positions correlated with both the height difference between the tractor cab and trailer roofs and the distance between the rear of the cab and the front of the trailer, and so that the base edge of the deflector is located at a pre-determined height above a given horizontal plane disposed below the plane of the cab roof and so that in all adjusted positions of the deflector the vertex of the included angle between the radii of curvature of the top and base edges of the deflector at the vertical center plane is located below the plane of the cab roof and on the said horizontal plane.

Abstract: ABSTRACT OF THE DISCLOSURE Train speed is controlled by propulsion train line (PTL) apparatus, which  sets a base level of propulsion effort, and by an advance train line (ATL) apparatus, which varies the propulsion effort up or down fro  the existing base level in accordance with under or over speed condition.   Each full cycle of ATL operation drive the PTL apparatus to the next high r or lower base level.  A propulsion error signal PE drive a comparator-clock network to generate clock pulses and an up/down signal to step the ATL register and this the PTL encoder to bring speed  within the desired range.   A speed control, brake error signal SCBE control normal train braking effort but is inhibited while  propulsion control remains effec-tive to reduce speed.  When the PTL encoder counts down to the rero propulsion level, the  clamp on signal SCBE is remove to activate  braking to further reduce  speed.     Station stops are controlled by a first trigger signal a preset distance in ap-proach to the station and two subsequent triggers at shorter distances to improve the  accuracy of the stop   Bach trigger signal applies a scaled value of train speed and a distance-to-go indication to an acceleration computer which continually computes the deceleration rate required to stop at the station When a comparison of the computed deceleration rate with a de-sired rate results in a preset ratio, the PTL encoder is driven down to zero to reduce speed in preparation for the station stopping action.   The apparatus finds use in rapid transit systems.   Novelty resides in the combination of apparatus to provide accurate speed control and station stopping.

Abstract: ABSTRACT OF THE DISCLOSURE           Hydraulic turbo machines including pumps and pump turbines having pivotally adjustable wicket gates are vulnerable to damage caused by the ingress of dirty water containing abrasive particles into the bushings in which the stems of the wicket gates are pivotally supported in the headcover and bottom ring.  This problem is overcome by the provision of individual seals between the end of each wicket gate and an adjoining surface portion of the headcover or bottom ring in which the bushings are located.  In addition seal water at a pressure in excess of machine operating pressure forces the seal ring into contact with the end of the wicket gate and also causes a slight flow of clean water outwardly between the seal and the respective end of the wicket gate, so as to keep the seal entry zone flushed clear of particulate material.

Abstract: VOLTAGE SUPPLY CIRCUIT FOR VOLTAGE-DEPENDENT CAPACITOR DIODE TUNING                   ABSTRACT OF THE DISCLOSURE            In a voltage supply circuit for voltage-dependent capacitor diode tuning, a d.c. voltage is produced by a.c.-d.c. conversion of an a.c. voltage which is obtained by amplifying an a.c. signal from an oscillator with the aid of a transistor amplifier of series-type feedback having an amplifying transistor having an amplification factor depending on a variable reactance coupled to an emitter of the amplifying transistor.  The variable reactance controls the amount of negative feedback to obtain the corresponding gain of the amplifier.  The degree of amplification decreases as the amount of the negative feedback increases, so that the output d.c. voltage will be stable, especially in a low voltage region.

Abstract: ABSTRACT OF THE DISCLOSURE A device is provided for converting a single-volume flushing cistern of the type having a water inlet, a water outlet, a valve mechan-ism operationally linked to a float lever for controlling the amount of water flowing into the cistern, a flush actuating means and a flushing mechanism operationally linked to the water outlet, into a selective volume flushing cistern adapted selectively to allow both partial and complete flushing.  The device comprises a hollow vessel insertable into the flushing cistern and adapted normally to rest on the bottom of the cistern and at least partially to surround the flushing mechanism and water outlet thereof.  The vessel is provided with an opening at its upper end for the entry of water therethrough and with at least one selectively openable port at its lower end.  Thus, the vessel is adapted to assume a first normally closed rest position in which the openable port remains closed for partial flushes.  At least a portion of the vessel is adapted to be pivotally displaced to assume a second displaced open position in which the openable port is opened to allow complete flushes.  The vessel is further characterized in that, upon the insertion of the device in the cistern, the opening of the openable port and the actuation of the flushing mechanism, the displaceable portion of the vessel is adapted, in its dis-placed open position, to engage and to be restrained in that position by a standard water level responsive part of the cistern.  In this way, the openable port is maintained in its open position during the entire flushing action and until the completion thereof, and whereafter the portion is released from its displaced position permitting the openable port to be closed.  This enables the conserving of flush water when the amount of waste in a toilet bowl is very small.

Abstract: ABSTRACT OF THE DISCLOSURE         Ultrasonic signals are transmitted alternately upstream and downstream in a fluent media.  A reference signal timed to occur at the estimated time of arrival of the alternate signals is used to ascertain whether the actual signals arrive earlier or later than the reference signal. Control circuitry responsive to the early and late signal generates two signal levels associated with transmission direction which adjusts the time position of the reference signal until it coincides with the actual arrival times.  One signal level is related to flow velocity.  The other signal level is related to sound velocity in the fluent media.

Abstract: METHOD OF MAKING A ROLLED METAL PISTON RING      ABSTRACT OF THE DISCLOSURE         A rolled steel oil control piston ring for internal combustion engines is of generally U-shaped cross section with a pair of opposed rigid sidewalls projecting inwardly of the ring from a central peripheral wall thereof.          A pair of flat-faced solid scraper rims formed by closed pleats rolled from the peripheral wall extend outwardly of the ring.  The ring is made by rolling flat strip steel stock through a series of profiled rollers by guiding the edges of the stock without deforming the same, while taking up dimensional variations of the stock by displacement of the central portion of the strip.  Pleats are formed in the central portion by the profiled rollers and the pleats are closed on themselves to provide the solid scraper rims.          An extrusion-like profile-reducing rolling step provides dimensional accuracy to the finished strip which is then punched to provide the vent openings in the peripheral wall, and coiled and cut to form individual piston rings.
