Abstract: SPECIFICATION          E. BERT W. GALER            INJECTION MOLD FOR MOLDING INTERNALLY THREADED PLASTIC ARTICLE     ABSTRACT OF THE DISCLOSURE         A core for the injection molding of plastic articles having internal threads, provides a means for readily releasing the article from the mold.  The core has a non-rotating, water-cooled center section to hold the molded article against rotary motion and a driven, water-cooled ring section for molding threads in the article.  Rotation of the ring section coupled with the holding action of the stationary center section releases the molded thread and ejects the article from the core by the axial force of the thread of the core bearing against the molded thread of the article.

Abstract: DRIVE TRAIN AND TRANSMISSION FOR FORAGE HARVESTER     ABSTRACT OF THE DISCLOSURE         A belt transmission has a clutch that keeps both belts moving in the same direction when the transmission is in the forward mode and slackens only one of the belts during the usually brief interval that the transmission is placed in its reverse mode with the other belt moving in the reverse direction.  Both belts share a common actuating lever having a lost motion coupling with one of the belts so that the lever can be placed in a neutral position in which neither of the belts is driven, even though power continues to be delivered to the transmission.          The drive train that supplies such power accomplishes a substantially right-angle drive from the swingable tongue of the machine without a gearbox by connecting a number of universal joints in a series that cuts across the corner between the swingable tongue and the main driven shaft of the transmission.

Abstract: ABSTRACT OF THE DISCLOSURE           Cells or multicell batteries are provided with vents comprising fiber-filled plastic tubes.  The plastic tube walls are formed of a hydrogen-permeable, liquid-impermeable, plastic material and the fibers which fill the interior of the tube serve to maintain an open gas diffusion passage through the tube.  The vents extend through seals between battery components into electrochemically active regions of the battery, into gas permeable regions of the battery outside of the electrochemically active regions, or both.  The fiber filled tube can terminate in the cell interior when the end positioned within the cell is sealed with a hydrogen-permeable, liquid-impermeable, plastic layer, or the tube can extend across the battery length or width.  At least one end of the tube is open to the atmosphere.

Abstract: ABSTRACT OF THE DISCLOSURE           A continuous process is disclosed for direct esterification of terephthalic acid with ethylene glycol to form low molecular weight polyester with recovery of excess glycol from reaction off-gases.  The terephthalic acid is mixed with an excess of glycol, the mixture is reacted at 280°-315°C in reaction product circulated from a reactor through an external heater and back to the reactor, and reaction product is withdrawn from the reactor for polymerization to high molecular weight polyester.  Vapor formed in the reactor are fed into the bottom of a rectification column where the excess glycol is recovered for direct reuse. The vapor feed is sprayed with condensate at 140-195°C in the bottom of the column to remove solids and maintain conditions suitable for obtaining less than 0.05 percent glycol in overhead distillate and 0.3 to 10 percent water in glycol condensate.

This disclosure presents an arrangement for automatically processing a coin box removal signal from a coin telephone station to the central office so that a determination can be made of the exact numbers and types of coins in the coin box at the time of its removal from the coin phone for collection. Each station is equipped with memories for three different types of coins and a coin box removal memory.  Flip-flop and logic gating control circuitry is responsive to interrogate and coin collect signals received from a central office for sequentially interrogating the memories and frequency shift keying the stored information to the central office.  Coin processor and memory circuitry in the central office interrogate the memories for initial and overtime deposits and coin box removal data and then store and accumulate the actual coin denominations for correlation in connection with coin box fill determinations and collection scheduling as well as the ascertaining of the exact numbers and types of coins in the coin box at the time of its removal from the phone.

Abstract: 21                  48,098 ABSTRACT OF THE DISCLOSURE         A single pair of headlamps that each contain a single on-focus light source and produce different but com-plementary beam patterns are mounted on a motor vehicle to provide a composite beam of intense non-glare light that is used for city, rural and turnpike driving and thus remains "fixed" and constant for all driving conditions.  The use of  a  single  light source in each headlamp improves the optical efficiency of the lighting system and provides both long range and short range illumination of the roadway with a minimum amount  of energy and drain on the electrical system of the vehicle.  The headlamps are not interchange-able  and must be mounted in proper relationship on the vehicle.  However, they can be of circular or rectangular shape  and  have  reflector  and  lens components  that  are preferably hermetically sealed to one another to provide sealed-beam type lamps, or which can be separated and thus form  housings  that can  be  opened  to permit  the  light sources to be removed and replaced.  When the headlamps are of sealed-beam construction, a coiled wire filament or a compact halogen-cycle type incandescent lamp can be used as the light source.  Standard compact incandescent lamps or 22              48,098 halogen-cycle incandescent lamps are employed in headlamps that are not hermetically sealed.

Abstract: Abstract of the Disclosure Techniques for a broad band high frequency acoustic investigation of a subsurface formation around a borehole are described utilizing a range of acoustic frequencies selected to produce detectable acoustic backscatter from grains within the subsurface formation.  The acoustic backscatter is detected and a spectrum thereof is produced and averaged over adjacent subsurface formation regions.  A subsurface formation parameter such as the frequency dependency of the attenuation of the backscatter is determined from an analysis of the spectrum to provide an indication of the granularity property of the subsurface formation.  Use of a broad range of frequencies enables a determination of the subsurface formation parameter over a large range of grain sizes.  In another technique the spectrum of the detected backscatter is modified to remove the effect of the frequency response of the system with which the investigation is made.  The modified spectrum may then be used to derive an indication of the granularity property of the subsurface earth formation such as its mean grain size or grain size distribution.
