Title: Flush control valve
Inventor: NESTICH R FRANK
IPC: F16K21/16
Filed: 1989-03-20
Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE A flush control valve (10) for metering a predetermined amount of flush fluid, or other liquid, to a facility, such as a urinal, to be flushed. The flush control valve (10) has a push button cap (166) that is actuated to cause the primary valve assembly (33) to open and distribute the flush fluid from the inlet chamber (35) of the flush control valve (10) to the outlet chamber (36) of the flush control valve (10). Depressing the push button cap (166) activates a timing assembly (109), the interior working components of which do not come in contact with the flush fluid controlled by the flush control valve (10), thereby eliminating corrosion to that critical portion of the valve (10). The timing assembly (109) is pneumatically operated and is effective through a diaphragm (108) to actuate a pilot valve assembly (83) which controls the opening and closing of the primary valve assembly (33). By virtue of the interaction between the diaphragm (108) and the stem valve element (79) in the pilot valve assembly (83) and the pressure of the flush fluid within the valve (10), and the control effected by a bleeder sub-assembly (130) in metering the flow of pneumatic fluid from a timing chamber(115) to an energizing chamber (120), the timing assembly (109) is returned to the unactuated disposition at a rate sensitive to the pressure of the flush fluid sothat a substantially constant volume of flush fluid is delivered by the flush control valve (10) over a wide range of flush fluid pressures.

Abstract: ABSTRACT OF THE INVENTION         This potentiometer presents a parallelepiped casing having a quadrangular plan and is provided with recesses for the coupling of the connecting terminals which are definitely joined by plastic deformation of the pivots of the casing.    It also incorporates by-pass holes for the terminals towards the ends of the resistive plate,  as well  as recesses  for securing the collector by deformable flanges existing at the edges of the collector.   The central hole of the collector is  flanged, constituting a bearing for the rotor-actuated cursor,  which incorporates  at  diametrically  opposed  areas  thereof,  as contacting elements with the resistive plate and the collector, pairs  of  countersunks  determining  rounded  supports  on  the elements.    These  elements  are  assembled  automatically  and continuously. The terminals form a part of a continuous band on which they are duly stamped, as occurs with the cursors and the collectors.  Each terminal-casing-resistive plate subassembly, on the one hand, and each rotor-cursor-collector subassembly, on the other, is firstly mounted, maintaining the continuity through the bands. Finally, one subassembly is secured to the other and the bands which maintained the continuity thereof are eliminated. The  resistive  plate  is obtained  from  an  electroisolating substrate on which a resistive paint is firstly applied and then a silver glaze, with intermediate drying phases in respective furnaces.

Abstract: MONOLITHIC COMPOUND-CERAMIC CAPACITOR                   Abstract of the Disclosure A green ceramic cake is formed having a center layer of fine-ceramic particles sandwiched between two outer layers of relatively coarse-ceramic particles.   The chemical compositions of the center and outer layers are all essentially the same.  The center layer contains a stack of spaced-apart patterns of electroding ink.  This cake is separated into many individual green monolithic ceramic capacitors each with electrodes extending conventionally to opposite ends thereof.  These capacitors are sintered to mature the ceramic, and conductive terminations are formed at the opposite ends in contact with the buried electrodes. The finer start powder of the center layer is relatively expensive, but the resulting fine grain homogenous grain structure in the finished capacitor permits closely spaced buried electrodes and generally a higher quality dielectric due to greater density and more homogenous composition than is achieved in the cheaper outer layer material.

Title: Self regulating temperature heater as an integral part of a printed circuit board
Inventor: HENSCHEN HOMER E
IPC: B23K3/04
Filed: 1989-09-25
Granted: 1992-01-14
Abstract: ABSTRACT:    A heater is secured to or embedded in a circuit board and is selectively energizable by current to melt solder in a connection or disconnection operation.  The heater is spaced from circuit board contact pads by circuit board structure material that transmits the generated thermal energy to the contact pads to melt solder or other fusible material.  The heater is preferably a self-regulating heater in the form of a copper substrate having a thin surface layer of magnetically permeable, high resistance material.  An alternating current of constant amplitude and high frequency is passed through the heater and concentrated in the surface layer at temperatures below the surface layer Curie temperature.  At higher temperatures the current is distributed through the lower resistance substrate to limit further heating.  A current return path or bus is disposed in closely-spaced parallel relation to the surface layer and establishes an electric field between the substrate and the return bus to bias current in the substrate toward the surface layer.          The return bus may be embedded in the circuit board or provided as part of external tooling employed to deliver energizing current.

Abstract: A backing for an absorptive device such as a disposable diaper or a sanitary napkin, said backing comprising a combination of two layers. The first layer which does not contact the wearer's skin is preferably comprised of a liquid-impervious layer of polymeric film or the like. The second layer is also preferably comprised of a polymeric film which has been made pervious to liquid by providing a multiplicity of relatively small proturberances, each ending in an aperture, substantially across its entire surface. The apertured protuberances, which resemble a tiny volcano in cross-section, exhibit a soft, highly consumer preferred tactile impression which is sometimes characterized as «silky». In backsheets of the present invention, the second layer is oriented so that the tiny volcano-like cusps of the second layer constitute the exposed portion of the backsheet. This minimizes the area of contact between the backsheet and the wearer's skin. In a particularly preferred embodiment of the present invention, the second layer is macroscopically expanded to provide a three-dimensional pattern in its surface, thereby increasing the amount of stand-off between the wearer's skin and the liquid impermeable first layer of the composite backsheet. The tiny apertures in the second layer substantially prevent occlusion of the wearer's skin by providing circulation of air between the first liquid impervious layer of the backsheet and the wearer's skin. This effect is enhanced even further when the first layer is macroscopically expanded to enhance the amount of stand-off between the wearer's skin and the liquid impervious first layer. The reduced contact area and the enhanced air circulation between the backsheet and the wearer's skin reduce the tendency toward perspiration and sticking of the backsheet to the wearer's skin.
