Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to an auger and to a plow including such auger.  This specification discloses an auger which when suitably mounted, is suitable for use even at the difficult terrain encountered in typical reforestation operations.  An auger in accordance with this disclosure has its axis extending in the direction of movement of the plow and is arranged to rotate in a direction opposing the forward movement of the plow.  The auger has a plurality of generally helical turns.  Sections of the ground engaging portions around the periphery of the turns have an angle of attack in a plane at a selected angle to the axis of the auger and other sections have angles of attack in planes at a different angle.  These ground engaging sections of the periphery are preferably teeth which because of the difference in angles discussed above attack the ground at different cutting angles.  The dislodged earth will as is normal with an auger be flung sideways as a furrough is formed, but it will also have a component of motion which is either forward or backwards in relation to the direction of travel of the plow. When, as previously explained the auger is rotating to oppose the direction of the plow, this forward or backward component of motion will depend on the rate of forward movement of the plow less the rearward displacement of particles caused by the auger.  The motion will be forward if the result is positive and backward if the net result is negative.

Abstract: IMPROVED CONTROL VALVE                  ABSTRACT OF THE DISCLOSURE      A temperature-responsive valve for controlling the flow of fluid substantially without being affected by the pressure of or the turbulence generated by said fluid, comprises a housing having a chamber therein, an inlet port communicating with said outlet port communi-cating with said chamber, a temperature deflectable partition having an aperture and a tube.  The tube extends from said inlet port past said aperture when the deflectable partition is in the position permitting a full flow of fluid.  When the temperature of the fluid transmitted to said partition reaches a first predetermined value, the deflectable partition snaps to restrict with its surface the flow of fluid into said outlet port and remains in that position until the temperature of said fluid transmitted to said partition reaches a second predetermined value.  The deflectable partition then snaps to permit the full flow of fluid into said outlet port.  The tube substantially eliminates the effect of the pressure and the turbu-lence of the fluid upon temperature at which the deflectable partition snaps to restrict the flow of fluid.  The temperature-responsive valve is especially useful in showers for protecting users from discomfort or scalding in the event the temperature of the shower water rises above the desired value.

Abstract: ABSTRACT OF THE DISCLOSURE The method for demodulating a frequency-modulated signal comprises considering the signal as being the projection, on an axis Ox, of a rotating vector rotating about a point O in a coordinate Oxy in such a way that the frequency variations of the signal correspond to the rotary speed variations of this rotating vector. After sampling the signal at a rhythm equal to 4 times a frequency F' in the frequency band of the signal, using an appropriate calculation, the position of the rotating vector is determined by means of two successive samples of the signal. The frequency variation of the signal between two times spaced by a cycle    is then deduced from the position of the rotating vector at these times.

Abstract: Multiple Transfer of Tacky Image Areas Using Prolonged Tack Toners Abstract of the Invention A surface having tacky image areas and nontacky background areas can be color developed by applying to the tacky image areas a prolonged tack toner, heating the toned image to a temperature sufficient to make the toner tacky, reducing the temperature of the tackified toned image below the tackifying temperature, the toner remaining tacky, and repeating the toner application, heating and cooling steps at least once.  The prolonged tack toned image can be used in single or multiple transfers to an image receptor.  The transferred image can also be toned with prolonged tack toner to generate an image of higher optical density.

Abstract: ABSTRACT         A "molecular p-n junction" is formed by an organic compound which has a molecule susceptible of electron donation and another molecule susceptible of electron acceptance, each of these two molecules within the same compound or molecule. Thus the compound consists of three molecular parts which may in other environments exist as separate molecules.  The electron donation molecule and electron acceptance molecule are separated by an intramolecular linkage or chain so that the three form one composite molecule.  The donor and acceptor molecules, if the intermolecular linkage is adequate and generally in the preferred range of 15 .ANG. to 25 .ANG., or generally between 10 .ANG. to 40 .ANG., is susceptible, under the influence of light, of donating an electron to the acceptor.  As such, the compound functions as a "molecular p-n junction".

Abstract: ABSTRACT          Disclosed is an improvement of scissors type and vetical feed type band saws wherein a rotatable subframe carries the movable head and is itself connected by a vertical pivot to the saw base.  Selective rotation of the rotatable subframe causes rotation of the cutting plane of the saw band with respect to the saw base and the workpiece vise jaws which are mounted on the base.  In this way selectively angled cuts can be made without reorienting the workpiece.

Abstract: MINIATURE DUAL-MODE, DIELEC-TRIC-LOADED CAVITY FILTER            Slawomir Jerzy Fiedziuszko, Inventor ABSTRACT OF THE DISCLOSURE A ceramic resonator element having high Q, high die-lectric constant, and a low temperature coefficient of reso-nant frequency is enclosed within a cavity to form a compos-ite microwave resonator having reduced dimensions and weight as compared to a simple cavity resonator.  A pair of tuning screws extend into the cavity along orthogonal axes to tune the structure to resonance along these axes at frequencies near the fundamental resonance of the ceramic element.  Sev-eral such cavities can be formed in a short length of wave-guide by the use of transverse partitions at spaced intervals and coupling between cavities can be accomplished by using simple slot, cross or circular irises.  In each cavity, a mode-perturbing screw is positioned along an axis 45° from each of the orthogonal tuning screws, such that resonance along either of the orthogonal axes is coupled to excite resonance also along the other.  The realization of complex filter functions requiring cross couplings is feasible by means of coupling separately to only one of the two orthog-onal resonant modes in the cavities.
