  • Alpha-cyanoethylphthalate and preparation thereof
    Patent number: 4056550
    Abstract: This invention relates to a method for preparation of a stereo isomer mixture of crystalline alpha-cyanoethylphthalate wherein the stereo isomer mixture is separated from the reaction mixture by precipitation. More particularly, the stereo isomer mixture is initially formed by reacting lactonitrile and a phthalic acid halide in an organic liquid solution at ambient conditions and the stereo isomer mixture precipitated therefrom by adding an organic precipitant liquid to the reaction mixture. By-products and side-reaction products can be washed from the reaction mixture prior to precipitation of the stereo isomer mixture to provide an alpha-cyanoethylphthalate product having greater purity than conventionally obtained. Additionally, the present alpha-cyanoethylphthalate composition can be characterized as a mixture of the meso and dl isomers wherein one isomer has a predominant weight ratio in the mixture.

  • Process for the production of a bodied silicone resin without the use of a catalyst
    Patent number: 4056492
    Abstract: A process for the production of a bodied silicone resin without the use of a catalyst comprising first hydrolyzing the organohydrosilanes in a homogeneous hydrolysis medium composed of water and acetone, removing the acid/water layer, adding at least 10% by weight of water based on the silicone resin hydrolyzate and heating the resulting mixture to at least 130.degree. C and more preferably at a temperature range from 140.degree. C to 160.degree. C. After this bodying step, water constituting at least 10% by weight of the silicone resin hydrolyzate as well as water-immiscible organic solvent may be added to the silicone hydrolyzate and the resulting mixture heated at elevated temperatures so as to remove all the water and acetone. This procedure of adding water may be repeated until the silicone resin hydrolyzate has an acid content that does not exceed 5 parts per million.

  • High pressure sodium vapor lamp stabilized for pulse operation
    Patent number: 4052636
    Abstract: High pressure sodium vapor lamps operated on sonic frequency pulses with short duty cycle in order to raise the color temperature are subject to arc instability near the electrodes and to overheating of the end closures, particularly that at the anode end when unidirectional pulsing is used. Stability and long life is achieved and overheating is prevented by using electrodes of cross-sectional area from 0.3 to 0.4 times the envelope cross section and lengthening the distance from closure to electrode tip so that the arc gap is less than 80% of the gas column length.

  • Ground fault protection system
    Patent number: 4044395
    Abstract: A conventional residential ground fault circuit interrupting (GFCI) device is utilized to control a traditional circuit interrupter in protecting a large power distribution circuit against ground faults. The GFCI device is connected in an energization circuit for a solenoid operable to open the interrupter contacts. A sensor responds to ground faults on the distribution circuit by impressing the current signal on one side of the energization circuit, thus creating a current imbalance effective to trip the GFCI device. Interruption of the energization circuit causes the solenoid to initiate opening of the interrupter contacts. In an alternative embodiment, the GFCI device is adapted to initiate opening of the interrupter contacts upon degradation of ground circuit continuity.
