Abstract: Abstract of the Disclosure.           An elongated finger-support member may be pivotally connected to the three-point hitch of a tractor or to the bed of a pickup truck.  The support finger is T-shaped in cross section and tapers to a point and includes a rearwardly facing hook on the top convex surface which supports the baled hay along its axial center.  A cross member is provided at the base of the finger for limiting penetration and supporting the baled hay when the finger is in a vertical position.  When the support finger is carried on a truck a frame is bolted to the truck bed and includes a cage extending over the hydraulic power cylinder and the cage functions as a stop for limiting the pivotal movement of the finger and fur-ther protects the cylinder from the hay.  The machine is positioned between the wheel wells of the truck such that the hay is sand-wiched therebetween when being transported.

Abstract: ABSTRACT OF THE DISCLOSURE       In rotary anodes which are journalled on two sides a problem occurs, notably as regards the bearing which is arranged on the side of the anode disc which is remote from the rotor.     The problem involves excessive discharge of heat via the shaft and the bearing.  A possibility of reducing the quantity of heat applied to the bearing consists in the increasing of the length of the anode shaft to increase the heat resistance.  However, the length of the X-ray tube is then also increased.  The invention provides a combination of smaller length, substantially free choice of the material of the anode shaft and hence overcritical speeds for the tube during operation by forming the anode shaft as a hollow rotor shaft coupled to the anode disc and a further shaft journalled at both ends to the respective bearings and connected to the hollow shaft.

Abstract: A TRACKING OSCILLATOR AND USE OF THE SAME             IN A FREQUENCY TO VOLTAGE CONVERTER                          ABSTRACT    A tracking oscillator includes an integrator and a hysteresis switch for tracking an input train of waves and providing an output train of square waves.  The output is fed back to the integrator to mark transitions between increasing and decreasing direction of integration in response to changes between a high and a low level in the output train of square waves.  The tracking oscillator is interposed between a limiter and a phase detector and is used to introduce phase delay to the output of the limiter.          The phase detector compares the output of the tracking oscillator and the output of the limiter to provide an output square wave train having a pulse width proportional to the phase delay introduced by the tracking oscillator.  A suitable circuitry, such as a low pass filter and averaging circuitry, is coupled to the output of the phase detector for converting the train of square waves into a DC output       r wherein the DC voltage is proportional to the phase delay.

Abstract: TITLE              CHANNEL, EVALUATION APPARATUS FOR POINT-TO-POINT COMMUNICATIONS SYSTEMS                         INVENTOR                Everett E. Stevens ABSTRACT OF THE DISCLOSURE A point-to-point high frequency communications system has a first set of frequency channels for transmission between a first terminal and a second terminal, and a second set of frequency channels for transmission between the second terminal and the first terminal.  The channel evaluation apparatus includes a sounding transmitter and receiver at each terminal.  These equipments operate in parallel with the regular communications system and provide the facility for real-time evaluation of all assigned channels using a sampling technique.  Each sounding transmitter periodically transmits  sounding signals in time-step sequence through its respective frequency channels to the sounding receiver at the other terminal.  The sounding signals for each channel are evaluated for transmission quality and this information is displayed.          The operator at each terminal may manually or automatically determine the desired channel of reception and this information which is then encoded on the sounding signals transmitted to the other terminal, is used by the operator at the other terminal to set the communication channel.

Abstract: ABSTRACT OF THE DISCLOSURE                A vehicle ventilating roof device or sunroof is provided.  The complexities and costs of existing types of sun-roof are greatly reduced by this invention.  A sliding reflective glass panel, located in tracks on the outside of the vehicle roof, is adapted to open or close a roof opening.  A tubular seal fixed around the opening contacts the panel, when in the closed position, to seal the opening.  A vacuum applied to the tubular seal flattens the tube to release it from contact with the panel.  This allows the panel to slide to its open position.          The simplicity of the invention facilitates ease of installation into a vehicle whilst minimizing costs.

Abstract: ABSTRACT OF THE DISCLOSURE   A mononose structure converts a pair of conventional skis into a twinski.  The mononose structure is a tip which includes a trailing portion of essentially the total width selected for, the width of the twinski and a leading portion converging forwardly in a curved nose; a right-hand pocket and a left-hand pocket separated by a central bridge section, the right-hand pocket having at least a lateral outside surface defined by a forward web section adapted to conform and butt against the outside edge of the tip of a conventional ski placed in the right-hand pocket, and having an inside edge of the central bridge section adapted to conform and butt against the inside edge of the tip of a conventional ski placed in the right-hand pocket; the left-hand pocket having at least a lateral outside surface defined by a forward web section adapted to conform and butt against the outside edge of the tip of a conventional ski placed in the left-hand pocket, and having an inside edge of the central bridge section adapted to conform and butt against the inside edge of the tip of a conventional ski placed in the left-hand pocket and means cooperating with and associated with the mononose and with the pair of conventional skis for clamping the tips of conventional skis rigidly thereto.  This provides the forward end of a twinski having an upwardly curved tip and bifurcated tail sections separated by a longitudinal slot.  The rear ends of the conventional skis are tied together by bridge means at the tails of each of the conventional skis.  This bridge means ad-justably and floatingly holds the tails of the conventional skis in a prede-termined, spaced-apart relation so that the lateral spacings are predeter-mined, but yet the tails are permitted to move vertically.  The twinski thus provided has extremely good manoeuverability, good pivot turnability, controlled turns at substantially all speeds, good support on powder snow and excellent manoeuverability in both packed and corn snow.  The four edges provide greater control and the interconnected tail section works independently.
