Abstract: ABSTRACT OF THE DISCLOSURE           Costume jewelry is manufactured through photofabrication processes form flat metal sheets to form items such as earrings and small pendants.  A standard photo-fabrication operation in-cludes covering a metal sheet with a layer of photosensitive, chemically resistive material commonly referred to as a photore-sist.  Portions of the covered sheet are exposed to light to out-line the earrings and pendants on the sheet.  The sheet is then developed and the exposed metal surface portions are chemically etched to remove excess metal and form the earrings and pendants.      Thereafter, surface treatments involve supplementary photofabric-tion operations to provide different colors and finishes on the earrings and pendants by etching, plating and staining the ex-posed metal surfaces, all of which are supplemented by the reten-tion of portion of photoresist layers of selected colors.

Abstract: ABSTRACT OF THE DISCLOSURE         Liquids and semiliquids, such as thixotropic gels, oil and greases, are delivered to a discharge means accord-ing to a method and through the use of an apparatus powered by hydraulic fluid under pressure which is controlled by a valve for passage to a hydraulic motor that is, in turn, coupled to a pump used to withdraw and pressurize the mater-ial for delivery by a conduit line to the discharge means having a discharge orifice that is either nonclosable or synchronously opened.  The material is discharged by control-led pressurization which is initiated and terminated by controlling the flow of hydraulic fluid to the hydraulic ? r in response to actuation of a trigger or switch on the discharge means.  A discharge gun and lubricator collar are two preferred forms of the discharge means.

Abstract: ELECTROLYTIC CATION EXCHANGE PROCESS FOR CONJOINT MANUFACTURE OF CHLORINE AND PHOSPHATE SALTS                          ABSTRACT Process electrolyzes hot, concentrated solutions of (1) as an anolyte, an essentially saturated aqueous solution of an alkali metal chloride and (2) as a catholyte, an aqueous solution containing 10 to 75%/wt. of phosphoric acid separated by a special high-normality cation exchange membrane producing anodic chlorine of high purity, cathodic hydrogen also of high purity and in the catholyte an alkali metal phosphate.  The process operates at temperatures of 75° to 105° at highest current efficiencies and with low power consumption.  With a KCl anolyte, potassium phosphate salts of any desired K:P atomic ratio are formed in the catholyte and which are useful in fertilizer and detergent applications.  The process requires a cation exchange membrane of normality in the range of 0.2 to 10 N or higher in which a significant proportion of the anion sites may not be covalently-bound to the material of the membrane.   Graphite electrodes are especially satisfactory in the process including specifically an anodized graphite anode and a ruthenium metal coated graphite cathode.

Abstract: ABSTRACT OF THE DISCLOSURE       This disclosure deals with a time delay cut-out circuit for the start winding of an AC electric motor. The circuit includes an electronic switch which is con-nected in series with the start winding and which may be selectively closed to energize the start winding.  Time delay means is provided which in response to current flow therethrough, provides a timing period.  An auxiliary coil is wound on the motor stator and supplies current to operate the time delay means.  The electronic switch is connected to respond to the time delay means which closes the elec-tronic switch to energize the start winding during the timing period.  The components of the circuit, except for the coil, are mounted in a capsule which may be plugged into the motor from the exterior of the stator.  The time delay means includes a heat responsive device, and the components are sized and arranged in the capsule to optimize the heat generation and dissipation properties and thereby obtain the desired operating characteristics.

Abstract: ABSTRACT OF THE DISCLOSURE        A signal generating system and an electronic organ utilizing a beam tube wherein a PWM (pulse width modulation) representation of a wave shape desired to be reproduced is stored in a memory. An oscillator activated by means such as a manual or pedal key produces frequency f, where f is the frequency of the note selected. This oscillator causes electronic emissions to sweep the pattern of the PMW representation at the fundamental frequency se-lected.      The PMW wave shape is read out repetitiously at the generated frequency and converted to an analog form by a low pass filter to produce a tonal quality having the wave shape corresponding to the wave shape stored in the memory.
