Abstract: Abstract of the Disclosure A tool-loadable biasing spring for a knob retainer plate securing a doorknob on its knob sleeve.  The plate is slidable transversely in the sleeve and has a central opening.  The biasing spring has a bight with a hook for engagement behind the linear forward border of the opening and with an axial offset for transmitting thrust to such border.  Spring legs extend unrestrained across the face of the plate into camming relation with forwardly diverging inner faces of the sleeve, so as to generate forward bias on the spring.  The legs have axial offsets with out-turned fingers to lock behind the plate.  For loading, the spring is held in resiliently contracted condition across the end of a holder tool, and the tool is inserted into the end of the sleeve until both the bight offset and leg offsets and fingers pass simultaneously through the retainer plate opening.  The spring is then released for self-movement into interlocked relation with the plate.

Abstract: ABSTRACT OF THE DISCLOSURE        Particulate dielectric material is processed by radio frequency (RF) energy while being simultaneously conveyed from an inlet to an outlet, by disposing the transmitting and receiving electrodes of an RF generator diammetrically opposite each other on the outside of a conveyor tube containing a screw conveyor, both the tube and screw being made of dielectric material.  A fiber-optic probe is located at one end to sense the temperature of the particulate material in the conveyor tube and is connected at the opposite end to an infrared sensor which provides an electric output signal proportional to the sensed temperature.  This output signal is coupled to a set point controller which provides an electric output signal representing a small temperature range above and below a selected set point temperature, and the latter output signal is coupled to a duty cycle regulator which operates to regulate the "on" time of the RF generator.

Abstract: ABSTRACT OF THE DISCLOSURE A fail-safe device is disclosed for removing power from circuitry to be controlled upon the occurrence of an undesired operating condition.  The device includes circuitry for generating a fail-safe signal that is normally within a predetermined frequency range unless there is an undesired operating condition.  It also includes power control circuitry for supplying power to the circuitry to be controlled only when the fail-safe signal is within the predetermined frequency range.  In a preferred embodiment, the circuitry for generating the fail-safe signal includes a programmable computer which regulates the circuitry to be controlled and which, unless there is an undesired operat-ing condition, such as a failure of the computer, also generates a sequence of bits in which a predetermined pattern occurs at a known frequency.  A comparator circuit compares this sequence of bits with the predetermined pattern and generates a variation in the fail-safe signal each time there is a match.  In the preferred embodiment, the power control circuitry includes an electro-mechanical relay for supplying power to the circuitry to be controlled when that relay is turned on and relay actuating circuitry for keeping the relay turned on when the fail-safe signal is within the predetermined frequency range. The power control circuitry may also include latch-out circuitry for keeping the relay off once it has been turned off and reset circuitry for enabling the relay to be selectively turned on once it has been turned off.

The phenolic foam has initial k values of less than 0.15 with sub-stantially no increase of k value over time and good density and compressive strengths.  The phenolic foam is prepared by foaming and curing a foamable phenolic resole composition containing an aqueous phenol formaldehyde resole, surfactant, fluorocarbon blowing agent, and optionally other additives with an acid foaming and curing catalyst in a substantially closed mold which exerts a restraining pressure on the foaming composition in excess of ambient atmo-spheric pressure of greater than about 3 pounds per square inch.  The aqueous phenol formaldehyde resole is essentially a phenol formaldehyde condensation polymer having a molar ratio of formaldehyde to phenol of from about 1.7:1 to 2.3:1, preferably from 1.75:1 to 2.25:1 and most preferably about 2:1. The resole has a weight average molecular weight greater than 800 and preferably from 950-1500.  The resole also has a number average molecular weight greater than about 350 and preferably from about 400 to about 600 and a dispersivity greater than about 1.7, preferably from 1.8 to 2.6.  The acid foaming and curing catalyst is an anhydrous aryl sulfonic acid having a pKa less than about 2.0 and which changes the compatibility of the phenolic resole with water.  The preferred anhydrous aryl sulfonic acid is a combination of toluene sulfonic acid and xylene sulfonic acid.
