Abstract: ABSTRACT OF THE DISCLOSURE         An adjustless V-belt having a compressive rubber layer made of heatproof rubber or coldproof rubber and an ad-hesion rubber layer laminated on the upper surface of said compressive rubber layer.  A group of first cogs protrude from the adhesion rubber and have a predetermined depth and arranged at a predetermined pitch   A cover canvas is stretchable in the longitudinal direction of the V-belt, and covers the first cogs and roots between the first cogs.  Rope tensile members are embedded between the adhesion rubber layer and the group of first cogs with a regular pitch line in such a manner that the tensile members form a cylinder and parts of the tensile members are in contact with the cover canvas.  The rope tensile members have a thermal contraction stress of at least 3.5 g/denier, the difference between the thermal contraction stress at 100°C and that at room temperature.  Short fibers are embedded laterally in the compressive rubber layer and a group of second cogs are formed on the lower surface of the compressive rubber layer.  The method comprises the steps of (1) winding a longitudinally stretchable cover canvas around a metal mold on the outer wall of which strip-like protrusions and grooves are alternately provided; (2) spirally winding rope tensile members subjected t-thermal elongation around the cover canvas; (3) winding an adhesion rubber sheet on the rope tensile members;  (4) winding a compressive rubber sheet containing short fibers laterally arranged, around the adhesion rubber sheet, thereby to form a molded belt blank; (5) placing a cylindrical mold in the inner wall of which a group of cogs are formed over the molded belt blank; and (6) heating and pressurizing the molded belt blank to permit a part of the adhesion rubber sheet to flaw to fill the grooves of the metal mold, and to permit a part of the compressive rubber sheet to flow to fill the grooves of the cylindrical mold, to either form two groups of cogs on the upper and lower surfaces of the molded belt blank, respectively or, a group of cogs covered with the cover canvas on the surface of the compressive rubber layer.

Abstract: POWER SUPPLY FOR A HIGH INTENSITY DISCHARGE OR FLUORESCENT LAMP                  ABSTRACT OF THE DISCLOSURE           This power supply for a high intensity gas discharge or fluorescent lamp exhibits near unity power factor with no third harmonic distortion, and facilitates highly efficient lamp operation with dimming capability. This is achieved by using an inverter to drive a resonant network that includes the lamp load.  A feedback circuit adjusts the switching rate of the inverter to equal the resonant frequency of the network. Sinusoidal output voltage is achieved, together with voltage multiplication to a level sufficient to ignite the lamp and keep it lit during dimming.  The inverter is driven by a switching regulator that is supplied with unfiltered, rectified ac power.  A filter capacitor, connected across the regulator output, is sufficiently large so as to filter at the frequency of the rectified ac input.  The regulator switching duty cycle is controlled in response to the average dc level across this filter capacitor. Lamp dimming is achieved either by adjusting the switching regulator dc output level or by varying the duty cycle of the inverter.  The high power factor low distortion regulator concept may also be applied in other applications where direct current power is derived from an ac line.

Abstract: ABSTRACT In a regenerative rotodynamic compressor, a portion of a disc-like impeller adjacent the impeller periphery extends radially through an annular chamber in the compressor casing concentric with the impeller, thereby dividing said chamber into two annular side channels, one on each side of the impeller,  The portion of the impeller lying in the annular chamber has scooped out annular cavities or recesses in its sides in which are disposed rings of aerodynamic blades, and fluid flow passing around the annular chamber from an inlet to an outlet  is caused to circulate repeatedly, flowing radially outward through the blading in the impeller cavities and radially  inward in the annular side channels alongside the impeller outside the impeller cavities.  Shroud rings at the blade tips form cores around which this circulation takes place.  The blades are cast integrally with the impeller disc or with the shroud rings.  The aerodynamic blades are designed so that the angle between the entry and exit flows of each blade is greater than 90°.

Abstract: BRIDGE FOR STRINGED INSTRUMENTS                           ABSTRACT          The present invention relates to a bridge for stringed instruments.  While the bridges of the prior art are effective in reducing the ability of the drums to vibrate, substantially increasing the tone sustaining capabilities of each string over that obtainable thereto-fore, it has been found, in practice, to be inconvenient to construct a bridge assembly to conduct the strings into contact with the bolts connecting the drums to the base member.  It is an object of the present invention to overcome the shortcomings encountered with such bridges. In accordance with the present invention, there is pro-vided an improved bridge for stringed instruments of the type including a base member, a plurality of drums, and means connecting the drums to the base member in end-to-end relationship for independent lateral movement in two orthogonal directions to separately adjust the length and height of each string.  The strings are conducted into engagement with the drums so as to apply an axial force to each of the drums to urge all of the drums axially into contact with each other and the first drum into contact with a fixed abutment on the base member.

Abstract: ABSTRACT OF THE DISCLOSURE A combination microwave and electric oven includes a damper mechanism for selectively and automatically introducing a forced air flow into an oven cavity.  A timer is provided for determining a microwave cooking period, wherein a magnetron is energized to perform the microwave cooking operation.  The damper mechanism is associated with the timer so that the damper is automatically placed in a first position wherein the forced air flow is introduced into the oven cavity when the timer is wound up to select a preferred microwave cooking period.  When the preselected time period has been counted by the timer, micro-wavegenerating is terminated and the damper automatically assumes a second position wherein the forced air flow is prevented from entering the oven cavity.  The damper is placed in the second position when electric cooking operations are performed so that the interior of the oven cavity can be maintained at high temperatures without excessive energy consumption.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention describes a pressurized three-compartment membrane cell for electrolyzing aqueous alkali metal halide solutions at low cell voltages and high cathodic current efficiencies.  Unitary electrode-electrolyte structures, in the form of electro-chemically active electrodes physically bonded to ion-exchange permselective membranes, divide the cell into anode, cathode and buffer compartments.  The buffer compartment feed is pressurized to maintain a positive pressure differential with respect to the anode and cathode compartment feeds.  The flexible unitary electrode-electrolyte structures are forced outwardly against electronically-conductive anode and cathode current collectors to provide uniform, constant and controllable contact between the bonded electrodes and their corresponding current collectors and thereby minimizing ohmic losses.  A three-compartment cell operated in this fashion not only minimizes the voltage required to electrolyze the halide solution, but also increases the cathodic current efficiency at high caustic concentrations by providing multiple hydroxide rejection stages in a single cell process.         The improvement in cathodic current efficiency is realized by forming a lower caustic concentration in the buffer compartment than in the cathode compartment, thereby reducing backmigration of OH- ions into the anode compartment.

Abstract: COSURFACTANT BLENDS FOR OIL RECOVERY SURFACTANT SYSTEM         Abstract of the Disclosure A first and second series of aqueous surfactant-cosurfactant-electrolyte systems are prepared at varying electrolyte concentrations using, respectively, a relatively water insoluble cosurfactant and a relatively water soluble cosurfactant.  The resulting systems are mixed with oil to be displaced or its equivalent and allowed to equilibrate so as to determine the salinity at which the microemulsion phases formed on said equilibration have approximately equal volumes of oil and water, thus giving the optimal salinity concentration for each surfactant-cosurfactant combination.  Similar equilibrations are made using at least one surfactant system which employs a cosurfactant of intermediate water solubility.  These systems are then used under the same or similar conditions to displace oil at the optimal salinity for each system and the resulting oil recovery percentage is plotted versus the salinity. Thereafter using the relationship that increasing the more water soluble component of the cosurfactant increases the optimum salinity value and vice versa, a cosurfactant blend is prepared so as to give a system which has  an optimum salinity essentially corresponding to the unique salinity.
