Abstract: ABSTRACT       A wheel support for a amall boat is described.  This wheel support comprises a bracket secured to the central portion of a boat transom, and an inverted Y shape frame carrying a pair of wheels at its wider end and pivoted to the bracket at its narrower end.  With the wheels on the ground and supporting the rear end of the boat, a person can not only easily move a boat by supporting the bow and, but also swing the boat about its longitudinal axis between  an upside up position and an upside down position, since the pivotal axis is arranged close to the center of gravity of the boat.  The devise is thus particularly useful for the consecutive operation of unloading the boat from a vehicle top carrier, the boat being in upside down position when loaded, of transporting the boat between the vehicle end the body of water, and of launching from the shore, the boat being then in upside up position.  The reverse operations are also easily effected and the frame can be detached from the boat when loaded on the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE Fluid operating mechanism providing stationary and rotary companion parts of a fluid coupling having in the rotary part a cylinder with a piston defining therein opposite chuck closing and opening cylinder ends, and ports in both coupling parts which, together with two fixed conduits, form fluid passages to the opposite cylinder ends, with each passage having an interposed check valve and an associated plunger, of which the check valve in either passage will open to admit fluid into, but will normally close to block fluid flow from, the assoc-iated cylinder end, and the plunger associated with the check valve in either pass-age will open this valve on being subjected to the pressure of fluid in the other passage. At least the plunger associated with the check valve for the chuck-closing, cylinder end is a stepped plunger with opposite larger and smaller faces, of which the larger face is subjected to the pressure of fluid in the chuck-opening c cylinder end and the smaller face is subjected to the pressure of fluid in the passage to the chuck-closing cylinder end ahead of the check valve therein, so that this check valve can be opened for blending the fluid in the chuck-closing cylinder end with fluid of a lower control pressure applied to the passage to this cylinder end ahead of the check valve therein on admission to the chuck-open-ing cylinder end of fluid lower than the control pressure. There is also provided a system of control valves in association with the mechanism for operating the same for high-low operation of an associated chuck requiring the latter to exert a heavy grip on work for an initial part of a machining operation thereon, followed by a lighter grip on the work for the final part of the machining operation.

Abstract: ABSTRACT OF THE DISCLOSURE      EtOH-H2O binary mixtures to serve as raw feed liquids for distillation and vapor treatment systems intended for the production of substantially anhydrous ethyl alcohol are desirably derived from the fermentation or enzymatic conversion of sugars.  A preferred source of sugars is honey which may be produced in massive volumes in environmental controlled structures containing vegetation, hives and bees which are associated with automated means for emptying the hives of their accumulated honey.  In one system, the honey is produced on honeycombs which are removed from the hives and emptied by immersion in hot water.  Honey is recovered from a water solution thereof by separation of melted wax and fermented to a 6-12% beer suitable for use as a raw feed liquid.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus is disclosed for controlling the sampling of a composite analog color video signal so that the analog signal is sampled at precise locations relative to the phase of the color subcarrier of the color video signal in the absence of modulation.  The invention thereby enables a digitized signal having a constant phase relationship relative to the unmodulated subcarrier phase to be provided which can be advantageously used in magnetic recording and reproducing apparatus.  Since the constancy of the location of the samples relative to the phase of the color burst is maintained prior to recording, there is no phase error that would pose a problem during reproducing of the signal.  The apparatus stores a set of reference samples of a selected number of cycles of the color burst interval of the color video signal and generates an output clock signal that is phase synchronized with the reference samples, subsequently stores sets of comparison samples of color burst cycles from subsequent horizontal video lines using the generated clock signal and detects any error in the phase location thereof.    The apparatus adjusts the phase of the generated output clock signal in response to any detected error signal and stores a new set of reference samples in the event that the error detected is beyond predetermined limits.

Abstract: RCA 74,738 Abstract of the Disclosure A composite filter in a color television receiver includes a bridged-T network and a chrominance bandpass filter for mutually separating the luminance and chrominance components of a color television signal.  In the bridged-T network, first and second signal paths are coupled between an input source of television signals and an output, the second path including a first reactance. A third signal path including a second reactance is coupled between an intermediate point in the second path and the input of the bandpass filter.  The first and second reactances are tuned to the frequency of the color subcarrier signal of the chrominance component.  A fourth, resistive signal path is coupled between the input of the bandpass filter and a reference potential.  The four signal paths form a first filter for attenuating the chrominance component at the output of the bridged-T network to provide a separated luminance component at the output of the bridged-T network.  The bridged-T filter and the bandpass filter cooperate to produce a double-tuned chrominance passband response for selectively passing signal frequencies of the chrominance component to yield a separated chrominance component at the output of the bandpass filter.

Abstract: FOCUS DETECTOR ABSTRACT OF THE DISCLOSURE Electro-optical focus detection apparatus for providing a signal indicative of the magnitude and polarity of focus error in a light beam impinging on a surface, such as a recording surface in a recording or playback system.  The detector includes a beam splitter for dividing the beam reflected from the recording surface into two reflected beams of equal power, and includes an aperture placed in the path of the two reflected beams.  The first reflected beam converges at a focal point before encountering the aperture and the second reflected beam converges at a focal point after encountering  the  aperture,  both  beams  thereafter impinging upon separate photodetector  elements.   The aperture reduces the light incident on the photodetec-tors from both reflected beams, and the apparatus is so configured that the powers of the reflected beams incident on the photodetector elements are  identical when the original  beam is in focus on the recording surface.  When the original beam moves out of focus with  the  recording  surface,  both focal  points of the reflected beams move in the same direction, to provide an increase in the light falling on one of the photodetector elements and a decrease in light falling on the other, such that the differential output derived from the photodetector elements provides a signal indicative of the magnitude and polarity of the focus error.

Abstract: Abstract:       A central processing unit for use in an electronic system is designed for executing instructions of variable length in which an operand specifier, i.e. an instruction for specifying the addressing mode of an operand, is independent of an operation code for determining the kind of an operation and the number of operands.  Each operand specifier is formed of one or more data bytes, and has a stop bit flag indicating whether or not the particular operand specifier is the last operand specifier.  By adding the stop bit flag, the operand specifier can be shared, and different processing car be executed with an identical operation code.  In a case where, when operation code decoding means has provided an output indicative of the last operand, the stop bit flag is not detected in the corresponding operand specifier, the corresponding instruction is detected as an error.
