Abstract: ABSTRACT           Apparatus for treatment of humans with ultraviolet rays has one or more mercury lamps, Xenon lamps or other radiation sources and associated re-flectors which establish a high-density radiation field in close proximity to the exit opening or openings.  The radiation is filtered so that the body of a person located in the region of the high-density field is exposed only to rays in the range of 315 to 400 nanometers.  The heat energy output of the radiation source or sources is sufficiently low to enable a person to stand long periods of uninterrupted exposure to radiation in the range of 315 to 400 nm so that a tanning effect can be achieved as a result of a single con-tinuous exposure for a requisite interval of time.  Alternatively, the appa-ratus is equipped with suitable heat absorbing and intercepting means, es-pecially if the radiation source or sources are high-pressure mercury lamps or Xenon lamps.  The apparatus can constitute a table model, a floor model, a ceiling model, a wall model or a combination of these.

Abstract: Abstract of the Disclosure Various improvement in a clarifier having inclined flow passages, the clarifier being capable of reversible operation wherein liquid to be clarified may be selectively caused to flow either upwardly or downwardly through the flow passages. The clarifier has channels adjacent the tops of the flow passages for collecting a relatively low density phase and a unique flow control trough simultaneously regulating liquid flow through a manifold above the flow passages while also forming an outlet passage for the low density phase.  A vertical flow manifold with an overflow arrangement regulates flow between the lower ends of the flow passages and a flow conduit external of the clarifer.  Means at either end of the flow channels may collect multiple phases, an intermediate phase preferably being recycled to improve either the rate or quality of clarification.  Finally, the clarifier includes a combined support structure and floccu-lating chamber as well as a seal arrangement for facilitating mounting of the inclined plates within the housing.  The clarifier is operable in a downflow mode with one or more low density phases being removed at the tops of the inclined passages.

Abstract: SKIPPED STITCH DETECTOR FOR CHAIN STITCH SEWING MACHINES            Abstract of the Disclosure The disclosure is directed to a method and means for detecting a skipped stitch, in the absence of a thread break, on a chain stitch sewing machine or the like.  The detector system includes a secondary thread tension system which functions to provide lateral pressure against an unbroken thread in the region between the primary thread tension means and the sewing needle.  Whenever  during the course of the sewing operation, there occurs a momentary malfunction in the chain stitch operation a momentary variation in tension in the unbroken thread occurs in the region between the needle and the primary tension device. This momentary reduction in tension enables a yieldable member to momentarily displace or deflect the thread.  The sensing de-vice detects such momentary deflection of the thread and initiates an appropriate control function.  A particularly advantageous such control function is the marking of the fabric in the area of the skipped stitch so that the defect may be easily observed and repaired in a subsequent inspection operation.  Appropriate for this purpose is the use of one-shot pulse control, in con-junction with an extendable marking device.  When a momentary loss of tension is detected, the marking device is momentarily actuated to imprint a mark on the fabric which can be easily detected later on by an inspector.

Abstract: Docket No. 5102 PREPARATION OF ALIPHATIC AND HETEROCYCLIC              ALPHA-KETO CARBOXYLIC ACIDS         Abstract of the Disclosure A crude alkali metal salt of an aliphatic or hetero-cyclic alpha-keto carboxylic acid is prepared by hydrolyzing a 5-alkylidene hydantoin or a hydantoin having the formula   in which R1 is a heterocyclic moiety in an aqueous solution of an alkali metal hydroxide.  The crude alkali metal salt of the alpha-keto carboxylic acid can be separated and recovered (e.g., by evaporating water therefrom to form a mixture of said salt and an alkali metal carbonate).  Alter-natively, the crude alpha-keto carboxylic acid can be con-verted to the corresponding free alpha-keto carboxylic acid by treatment with a strong acid.  The resulting alpha-keto carboxylic acid can then be recovered (e.g., by extracting with ether and evaporating the ether therefrom).  The alpha-keto carboxylic acids have many uses which may include use as starting materials for amino acid synthesis, use as pharmaceut-icals against uremia, use as catalylitic materials in the co-polymerization of unsaturated monomers and as hair treating agents.

Abstract: ABSTRACT         In the float process for flat glass manufacture, on a molten metal bath there is forward flow of molten metal entrained by accelerating glass over an upstream return flow of cooler molten metal which is received in a deepened region of the bath.  Contact of the cooler molten metal with molten metal in the deepened region heats the cooler molten metal and local temperature variations in the molten metal are minimised.          Upstream molten metal flows are drawn from that deepened region to replenish the molten metal entrained by the accelerating ribbon of glass, so that the risk of local temperature variations in the molten metal supporting the accelerating ribbon is reduced and distortion in the undersurface of the ribbon is minimised.

Abstract: Campe 1 CURRENT CONTROL SYSTEM FOR A STEPPING MOTOR                 ABSTRACT OF THE DISCLOSURE     A conventional stepping motor has an optical disk connected to its rotor,  Optically generated pulses from the disk are used to generate a signal indicating the speed of the rotor.  A code converter converts the speed signals into a binary-encoded power-required signal for feedback to control the power delivered to the coils of the stepping motor so as to maintain a constant step-ping speed.  The encoded power-required signal is delivered to a binary comparator which delivers an output pulse of one binary sense or the other.  A clock driving a counter generates a binary count having the same number of binary levels as the encoded power-required signal fed to the comparator.  The output of the counter is also fed to the comparator.  The comparator delivers an output of one binary sense when the clock count is less than the binary-encoded power-required signal and an output of the other binary sense when the counter output is greater than the power-required signal,  Therefore, the output of the comparator is essentially a square wave having a frequency equal to the frequency of the clock delivered to the counter divided by the count modulus of the counter,  The output of the comparator is used to gate the drive signals of the step-ping motor at a rate substantially higher than the normal stepping rate of the stepping motor and higher than the normal maximum audible frequency.  Therefore, the stepping motor drive pulses are effectively chopped by the output of the comparator,  The duty cycle of the chopped signal controls the ON versus OFF ratio and thus the power sup-plied to the stepping motor coils.

Abstract: ABSTRACT:              A microwave antenna comprises a ground conduc-tor and a dielectric sheet supporting both an array of antenna elements and feeder lines to which the elements are connected in shunt and which are at angles to  the direction of polari-zation of the antenna.   The elements may be fed from a common central feed point.  A suitable pattern of feeder lines com-prises a plurality of parallel regularly-spaced lines enclos-ing a given n angle to the direction of polarization and inter-sected by a single feeder line enclosing the mirror-inverted angle to the direction of polarization.  The feeder lines are suitably of much higher impedance than the elements.  Power tapering across the antenna apertures giving good polar diagrams is readily obtainable.

Abstract: Abstract of the Disclosure A process for producing fire-refined metallic copper, copper-nickel, or cobalt nickel from their sulfides.  A molten substantially iron-free metal sulfide bath is established in a tiltable non-rotary sealed refractory-lined converter.  Oxygen in gas concentrations and amounts effective to achieve bath temperature levels required for high reaction rates is directed upwardly into said molten bath through several subsurface injectors until the overall quantity of oxygen reacted there-with is about the stoichiometric amount required to convert substantially all of the sulfur present in the bath to sulfur dioxide, and sulfur dioxide is introduced through said sub-surface injectors as shielding fluid surrounding the oxygen in regulated amounts effective for protecting the injectors and surrounding refractories until the sulfur content of the molten bath is reduced to less than about 5 percent, at which time the sulfur dioxide is replaced with hydrocarbon fluid.
