Abstract: ABSTRACT OF THE DISCLOSURE      In a pivotally mounted rock drill boom and feed bar apparatus the boom and the feed bar positioner include angle sensors comprising cam actuated fluid pressure regulating valves.  The pressure regulating valves are disposed in a control circuit which includes a pilot pressure fluid actuated control valve which senses an unbalanced pressure signal gener-ated by one of the sensors in response to pivotal movement of the boom.  The control valve responds to the unbalanced pressure condition by valving pressure fluid to the feed bar positioner actuator to maintain the feed bar in a predetermined directional attitude.  The angle sensor responsive to pivotal movement of the boom may be adjusted independent of movement of the boom to cause a change in the directional attitude of the feed bar as desired.

Abstract: ABSTRACT      Reflected light from the record in a optical disk player is directed at a string of photo sensitive diodes. Two adjacent diodes of this string of diodes receive light from a selected portion of the track on the disk. The outputs of these two adjacent diodes are summed together to generate the output signal for the optical disk player.  The outputs of the two diodes are also subtracted from one another to generate a differ-ential signal for tracking purposes.  The magnitude of this differential signal is a measure of the relative magnitudes of the signals on the two adjacent diodes and therefore is one indication of how much of the light from the selected portion of the track reaches each of the diodes.  When this differential output becomes larger than a preselected value, decode circuitry responds by changing the combination of adjacent diodes in the string to generate the video output signal and the difference signals.

Abstract: ABSTRACT An automatic swimming pool cleaner comprised of a car adapted to travel underwater along a random path on the pool vessel surface for dislodg-ing debris therefrom.  The car wheels are driven by a water powered turbine to propel the car in a forward direction, along the vessel surface.  In order to prevent the car from being driven into a position, as for example against a vertical wall, from which it cannot emerge, a wheel geometry is employed which, upon contact, develops a horizontal force component parallel to the vertical wall, to thus enable the car to spin off.  Alternatively, or in combination, a water flow produced reaction force can produce a torque to turn the car with respect to the engaged wheel to enable the car to spin off. The car is designed with a low center of gravity and a relatively buoyant top portion so as to produce a torque which maintains the car correct side up when on the pool bottom.  Means are provided on the car for producing a water flow having a force component perpendicular to the vessel surface to provide good traction between the car wheels and the vessel surface.  Further, a water flow produced suction is created adjacent to the vessel surface for collecting debris into a basket carried by the car.  In addition, one or more hoses is pulled by the car and whipped by water flow to sweep dirt from the vessel surface.

The height "S" of each spacer is greater than the sum of (1) the difference between the unloaded height and the loaded height of the isolator and (2) the minimum height of a jack suitable for loading the isolator in place so that the isolator can be inserted in position on the pedestal under the inertia block in unloaded condition and loaded using the jack and the spacer (or spacers) installed while the inertia block and forging hammer are temporarily supported on piers which include removable spacers that are taken out after the isolators are installed.

The secondary windings are divided into winding stages and there are provided lines and switches, by means of which these winding stages can be selectively connected in series.  Since the phase angle of the voltage in each winding stage coincides with the angle of the corres-ponding winding, it is possible to vectorially add in this manner partial voltages with different phase angles, so that at the output terminal of one winding there appears a composite voltage whose phase angle is aligned in the same direction as said one winding or, in relation to such direction, is shifted through a predetermined angle value in clockwise direction or in counterclockwise direction.

Abstract: PROCESS FOR ANNEALING STEELS     ABSTRACT OF THE DISCLOSURE           A process for the annealing of hypoeutectoid steels wherein a steel is rapidly heated to a temperature above the upper transformation temperature of the steel to convert the steel to austenite and carbides, followed by cooling of the steel.  The rate of heating of the steel is such as to cause dissolution of most of the carbides in the austenite thus formed, thereby leaving small particles of undissolved carbide in an amount sufficient to serve as nuclei for the precipitation of upper transformation products on cooling.  Steels processed in accordance with the process of this invention are characterized by improved ductility and toughness as well as good machinability characteristics.
