Abstract: CENTRAL DESK AIR CONDITIONING         CONTROL SYSTEM               ABSTRACT OF THE DISCLOSURE            A central desk air conditioning control system wherein each individual room unit is connoted to a central desk location by a pair of control conductors.  At the central desk location a SPST switch is connected across each pair of control conductors and effective, when closed, to place the connected individual room unit in a low energy mode.  In the low energy mode, power relay drivers for major energy-consuming load  such as refrigerant compressors and electrical resistance heaters are disabled, while other loads, such as fans and control circuitry, remain energized. For the event that voltages are inadvertantly connected to the control conductors, a protective network is included in each individual room unit to prevent damage to its circuitry.  The control circuitry for each individual room unit includes "Freeze Sentinel" circuitry for energizing a heating load when required to ensure that room temperature does not fall below 40°F regardless of user control settings.  In the low energy mode the Freeze Sentinel circuitry continues to operate manually.

Abstract: PUSH BUTTON SWITCH WITH SPIRAL              ABSTRACT OF THE INVENTION      The conventional push button switch which is generally found on lamps and appliances is constructed so that depressing the push-button causes a rotary switch motion within the body or the switch.  The components which convert the linear motion of the push-button have consisted of a metal spiral stem and a cooperating metal pushbutton.  In addition the spiral stem has been provided with a washer at its lower extremity.    The present invention provides for the spiral stem and washer to be molded as a single plastic component.          The cooperating push button is provided as a plastic component or as a metal component with a plastic insert.          The improvement described serves to reduce the number of component parts in a pushbutton switch as well as isolating the operator of the push button from the internal electrical components.

Abstract: ABSTRACT     The  invention  is an  improved  thermoelement which comprises a graphite/boron carbide thermocouple, the arms of which are constructed as a tube and a rod, arranged con-centrically inside the tube, which are electrically connected at one end.   One of the arms of  the thermocouple consists essentially of boron carbide formed from self bonding boron carbide by pressureless sintering.  Prefabricated sleeves of high-purity, boron-oxide-free  hexagonal  boron  nitride  are used between the arms of the thermocouple as spacers.   Only the end of the arm of the thermocouple constructed as a rod is secured in an electrically conductive connecting piece and the arm is freely mobile in the direction towards the cold junction.  As the material for the arm of the thermocouple constructed as a rod, there can be used, for example, boron carbide having a coarse-grained structure and a density of from 60 to 80% TD, which has been manufactured from boron carbide powder having bimodal particle size distribution by means of  extrusion,  followed  by pressureless  sintering  at from 2000 to 2250°C.         The thermoelement can also be manufactured in one operation by means of pressureless sintering of  the boron carbide powder in situ.  Such a thermoelement comprises, for example, a flexible graphite cord for the arm of the thermo-couple constructed as a rod, a boron-nitride envelope and a boron carbide casing,  the  envelope  and  casing  having  been formed from powders sintered in situ without pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           Here is disclosed a waist band for diaper to con-nect the front and rear waists at each side.  In contrast with the pressure-sensitive and adhesive tape of prior art which necessarily forms an overlapping portion of said front and rear waists at each side of the diaper when the latter is put on the user, this waist band has not only a function to adjust a circumferential dimension of the waist but also the fastening function of the conventional adhesive tape.          The waist band disclosed herein has a relatively large length including an area of low rigidity (or high flexibility) serving for said adjusting function and another area of high rigidity serving for said fastening function.  Furthermore, this waist band is made of basic material consisting of non-woven fabric having high flexibility and plastic film which is at least partially melted into said nonwoven fabric inte-grally therewith so that said area serving for fastening function may have a desired high rigidity.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a low cost flexural mechanism upon which tracking mirrors and the like used in optical systems may be mounted.  The flexural mechanism is made from a single sheet of metal by placing a desired shape or pattern in the metal.  The resulting shape is then formed into a base, mounting surface, and flex arms.  The mechanism is stiff in directions other than rotation, has low noise, has low thermal sensitivity,  and can be made in any practical size.  The flexural mechanism can be designed to place the pivot axis at the center of gravity of the mass being rotated, even when the center of gravity is outside the flexural mechanism.

Abstract: ABSTRACT OF THE DISCLOSURE     A low inertia springless check valve suitable for opera-tion at high frequencies in a hot environment against a high cyclic back pressure with a relatively constant low input pressure, such as in an automotive engine exhaust air induction system.  The valve has a circular elastomeric diaphragm mounted on a supporting frame by means of a retainer disk, a fastener and a diaphragm limiter.          A central portion of the diaphragm is compressed between the disk and limiter to cause the originally flat diaphragm to become dished and biased towards the valve seat.  The limiter is designed to stabilize, in the flow direction, a portion of the diaphragm extend-ing along the entire length of an adjacent diameter of the diaphragm.          The retainer disk also functions in part as a diaphragm motion limiter in the check direction.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to improved drag reduction agents for aqueous solutions which comprises a polymeric complex which is a terpolymer of acrylamide/metal styrene sulfonate/methacrylamidopro-pyltrimethyl ammonium chloride.            The metal styrene sulfonate is an anionic monomer, while MAPTAC is cationically charged. These acrylamide-based polyampholytes have approximately 1 to about 50 mole % of the anionic monomer and approxi-mately 1 to about 50 mole % of the cationic moiety present within the macromolecular structure. These groups are not necessarily present in an equimolar charge ratio. The excess undissociated charge allows for facile dispensability or solubility of the poly-ampholytes into fresh water.
