Abstract: This invention relates to a phenolic resin composition comprising a phenolic resin admixed with and/or modified by one or more functionalized organosulfur compounds. This invention also relates to a rubber composition comprising (i) a natural rubber, a synthetic rubber, or a mixture thereof; (ii) one or more phenolic resins; and (iii) one or more functionalized organosulfur compounds. The interaction between the component (i) and the components (ii) and (iii) reduces the hysteresis increase compared to a rubber composition without the component (iii), upon curing the rubber composition. The invention also relates to a process for preparing the phenolic resin composition, a process for preparing the rubber composition, and a process for reducing the hysteresis increase caused in a rubber composition when a phenolic resin is added to a rubber composition.

Abstract: This invention relates to a process of mixing a phenolic resin and one or more functionalized organosulfur compounds into a rubber composition comprising a rubber component. The interaction between the phenolic resin component and the functionalized organosulfur compound component with the rubber component reduces the hysteresis increase compared to a rubber composition without the functionalized organosulfur compound component, upon curing the rubber composition. The invention also relates to a rubber composition prepared according to this process and a rubber product formed from the rubber composition.

Abstract: Condensation curable poly(fluoroorgano)siloxane-poly(silarylene)siloxane block copolymer compositions having a glass transition temperature not exceeding about −54° C. and excellent solvent resistance have been found useful as sealants. Polyalkoxysilylorgano compounds, such as 1,4-bis[trimethoxysilyl(ethyl)]benzene have been found to be effective as cross-linkers.

Abstract: A fluorosilicone crosslinker and method for making is provided. Reaction is effected between a silanol terminated polyfluoroalkyl silicone fluid and a polyalkoxysilane in the presence of a Platinum Group Metal catalyst. The fluorosilicone crosslinker can be used in combination with a silanol terminated fluoroalkyl substituted polydiorganosiloxane to formulate a neutral, condensation curable, solvent resistant sealant.

Abstract: An electrical switch assembly includes a snap action switch which is actuated from one to another conduction state by a snap action interface mechanism moved by an external actuation element between first and second corresponding positions. The snap action interface mechanism prevents the snap action switch from operating improperly when the external actuation element is of the type which provides a slowly moving, low actuation force. A preferred embodiment has as a part of the interface mechanism, a lever having a ferromagnetic portion which snaps between the first and second positions under the influence of at least one magnet. The switch assembly is particularly suitable for actuation by the bimetal coil strip which commonly forms the temperature responsive element in a thermostat.

Abstract: In an electronic thermostatic circuit, a resistive bridge network is employed to sense the level of the ambient temperature. The bridge includes three legs having fixed resistors and one leg having a temperature sensitive resistor as well as a serially connected adjustable potentiometer. The adjustable potentiometer is adjustable to provide a selected set point for the operation of the thermostat within a given range of temperatures. The adjustable potentiometer is provided with a shaft to which an adjusting knob having a pointer thereon is secured by means of a slip fastener. Calibration of the assembly is accomplished by turning the knob with its pointer pointed in a preferred direction then holding the knob while adjusting the shaft and the associated potentiometer until the bridge output corresponds with the value indicated by knob pointer.

Abstract: A room thermostat having an electronic circuit board mounted in a cover and attached to a base member. A space is provided between the back side of the circuit board and the front of the thermostat cover whereby air can pass along the back side of the circuit board to "air wash" for removing heat which is generated by the electrical components mounted on the front side of the circuit board. The front side of the circuit board has a cover over the electrical components for shielding the heat from the components from a temperature responsive element. The temperature responsive element is mounted in a channel provided by the thermostat cover and shield to allow air flow past the temperature responsive means through a channel which includes the space between the thermostat cover and the base.

Abstract: A clock thermostat apparatus adapted for controlling temperature conditioning apparatus maintains a normal control temperature in a space and during certain selected time periods deviating from the normal temperature control by resetting the normal temperature control to some lower temperature for comfort and energy conservation. The clock thermostat apparatus has a manual temperature selection means and a manual temperature deviation selection means for selecting the normal control temperature and the amount of reset or deviation during the selected time period. A connection means is provided between the temperature selecting means and the temperature deviation selection means to turn the temperature deviation selection means to a lower value when the temperature selection means is moved to some predetermined low temperature.

Abstract: A thermostat adapted for controlling heating and cooling apparatuses has a temperature control point adjustment means connected to a changeover switch means whereby upon the adjustment of the temperature control point adjustment means in a first range to select a cooling control point, the changeover switch means only connects the thermostat to the cooling apparatus and when the temperature control point adjustment means is in the heating range, the changeover switch means only connects the thermostat to the heating apparatus. The limited range of temperature selection in the first and second range is an energy conservation feature of the thermostat.

Abstract: An adapter wall plate for mounting a replacement thermostat on a wall wherein the adapter wall plate attaches to the existing wall plate of the thermostat being replaced thereby eliminating the necessity of disconnecting the wires leading from the existing wall plate to the remote control apparatus.
