Abstract: ABSTRACT OF THE DISCLOSURE              In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by projecting a series of two-dimensional views of an object field onto a lenticular screen. Substantially uninterrupted and non-overlapping condensed, or lineiform, images of the two-dimensional views are formed beneath each lenticule of the lenticular screen by setting the number M of these images in the image band beneath each lenticule, and hence the total number of two-dimensional views projected, equal to wm, where w is the lenticule width and m is the width of each condensed image. In order to project the required number M of two-dimensional views while avoiding gaps between adjacent condensed images, the projection lenses and the associated film frames are positioned along a plurality of adjacent, parallel, straight lines in a manner such that the apertures of the lenses are effectively in edge-to-edge contiguous relation.

Abstract: ABSTRACT OF THE DISCLOSURE      This operating means comprises a circuit-breaker closing spring, a rotatable spring-controller mounted for rotation between first and second dead-center positions with respect to said spring, and means for transmitting charging forces to the spring in response to rotation of the spring-controller in a forward direction from said second toward said first dead-center position.  The spring acts to dis-charge and thereby further rotate said spring-controller in a forward direction when the spring-controller has been rotated in a forward direction past said first dead-center position.  Discharge of the spring drives the spring-controller into said second dead-center position, following which the spring-controller oscillates about said second dead-center position to dissipate excess energy then remaining in the parts.      Means is provided for closing the circuit breaker in response to said forward rotation of the spring-controller into said second dead-center position, and this means comprises: a mechanically trip-free operating mechanism coupled to the movable contact of the circuit breaker and a linkage interconnecting said spring-controller and said operating mechanism through a pin and slot coupling.  The pin and slot coupling (i) transmits closing force between the spring controller and the operating mechanism during spring-discharge, (ii) allows the spring-controller to oscillate about said second dead-center position without actuating the operating mechanism, and (iii) allows the spring-controller to be moved from said second to said first dead-center position during spring-charging without act-uating said operating mechanism.

Abstract: Abstract of the Disclosure A manually-operable tool is provided for insertion between the inboard and outboard caliper-mounted disc brake pads for the purpose of spreading the pads to facilitate placement over the rotor.  The tool employs a screw having an elongated partially-threaded shank and a handle at the rearward end for manually rotating the screw about its axis.  Supported on a non-threaded portion of the screw shank is a pivot-stud body having pivot studs extending laterally in opposite directions.  Supported on the pivot studs, on each side of the screw shank, is a pair of scissor-like jaw levers or spreaders.  Supported for sliding movement on the screw shank rearward of the pivot-stud body, i.e., between the pivot-stud and the shoulder of the handle, is a shoulder-stud body having camming studs extending laterally in opposite directions into the rearward jaw openings of the scissor-like spreaders.  Threaded on the screw shank forward of the pivot-stud body is a shoulder-nut body having camming studs extending laterally in opposite directions into the forward jaw openings of the spreaders.  When the screw is turned in a proper direction, the forward and rearward sets of camming studs are moved toward each other into the crotches of the scissor-like spreaders to spread both pairs of spreaders, thereby to spread, or to maintain at spaced separations, the inboard and outboard disc brake pads.

Abstract: ABSTRACT OF THE DISCLOSURE The disclosure relates to an advantageous process for the production of seamless tubular products with mill equipment requiring minimum capital expenditure. The starting material for the process typically is a short, square billet derived from a continuous casting process. The billet is first processed in a piercing press, in a manner to provide a generally circular outer contour and also to pierce the billet axially substantially through-out its length. After the piercing press, the billet is processed in a piercing-type alongator, which may be of either two-roll or three-roll configuration and serves to effect a substantial (e.g., about three or even four to one) elongation of the billet, and also a significant reduction of its wall thickness. The elongated billet is then processed in a multiple stand mandrel mill, which serves to further elongate the workpiece, by a factor of around three to one, and further reduce both its wall thickness and its outside diameter. At this stage, it may be desirable to further process the tubular shell in which case the tubular shell is re-heated and processed in a more or less conventional manner in a stretch reducing mill. In mills where the starting billets are available in cylindrical form, the piercing press may be eliminated, and the billet may be both pierced and elongated in the piercing-type elongator. Significant to the invention is the utilization of a piercing-type elongator to achieve a significant degree of elongation, in conjunction with a mandrel mill, which may be, if desired, utilized at significantly less than its maximum theoreti-cal elongation capability.

Abstract: ABSTRACT OF THE DISCLOSURE          Method and apparatus for desalinizing water.  Salt water in an evaporation zone is provided with heat of vaporization by a heat pump which transfers heat to the water from a thermal sink.  The evaporation zone is maintained at subatmospheric pressure so that the salt water boils at a temperature at least about 10 degrees above the ambient dew point.  The pressure in the evaporation zone is maintained at a low level by a vacuum pump and by condensing the vapor in a condensation zone from which fresh water is collected.  The heat of condensation is dissipated into a "cold" sink if available or by a heat dissipat-ing means such as an evaporative cooling apparatus.  Energy efficiency results from the ability of the heat pump or pumps in the system to operate at a high coefficient of performance.
