Abstract: A jumpsuit with a dropseat panel concealed by a folded pocket panel. When the dropseat is opened, the upper free edge of the pocket has a length selected such that it controls movement of the dropseat panel and its attached waistband, maintaining the waistband in contact with the wearer's body whereby the waistband cannot fall into a toilet.

Abstract: A topstitch guide for a sewing machine comprises a guide member positioned immediately prior to the presser foot and extending from the right side of the axis along which the topstitch is to be applied to a composite fabric to the left side of the axis. The composite fabric is folded along the principal seamline uniting the individual fabric components. The tip of the guide fits within the fold and engages the principal seamline so as to guide the composite fabric during the topstitching process.

Abstract: A capo for simultaneously adjusting the pitch of a stringed musical instrument. A worm-and-sector gear provides for adjusting the pressure exerted on the strings of the instrument.

Abstract: A pair of wire electrodes in an electrostatic precipitator is replaced by a single rigid discharge electrode. Shrouds on the upper end of the rigid discharge electrode cooperate with the original supporting and locating means on the upper high voltage frame to suspend the rigid discharge electrode midway between the vertical grounded electrodes. Suspending means on the lower end of the rigid discharge electrode provide for suspending the weights originally suspended from the bottoms of the wire electrodes from the rigid discharge electrode in their original positions.

Abstract: A remote indicator system for determining at a remote location when incoming mail is present in a mailbox. A light port in the mailbox admits outside ambient light onto a first photodetector on the bottom of the mailbox. When no mail is present, the first photodetector produces a first signal indicating that no mail is present. When incoming mail is present, the light to the first photodetector is interrupted, causing the first photodetector to produce a second signal, indicating that mail is present. A second photodetector positioned outside of the mailbox disables the first signal when the outside ambient light is below a given intensity, and a switching means associated with the manually operable flag disables the first signal to distinguish between incoming and outgoing mail.

Abstract: In gas chromatography wherein only the more volatile components of a multi-component sample are of interest, the sample is injected into a hot vaporization chamber containing a packing material. An inert carrier gas sweeps the resulting vaporized gases through a second packed column at a lower temperature than the vaporization chamber. After the more volatile components of interest have passed an intermediate conduit, a backflushing stream is fed sequentially through the second column and the vaporization chamber, exhausting through a vent. Simultaneously with opening of the vent, and beginning of the backflushing, a further stream continues to drive the portion of the first stream containing the more volatile components toward and through a chromatographic analytic column.

Abstract: A protective device for use when changing the diaper of a male infant. The device comprises a transparent shield suspended between the user's face and the infant, the shield being supported by straps or the like engaging the user's neck or shoulders.

Abstract: The new free end formed when a portion of flexible sheet material is severed from a roll contained in a box is prevented from retracting into the box by frictional engagement between the free end and a strip of abrasive material near the cutting edge mounted on the box. A portion of the box closure resiliently urges the free end into contact with the abrasive material.

Abstract: An oil-impermeable curtain is sealed to a vessel's hull at the top and lateral sides around a rupture, the bottom of the curtain being not sealed to the hull. This forms an open downwardly-facing pocket for containing oil leaking from the rupture.

Abstract: A miniature strobe-type flashing safety light source, to be worn by a person or pet after dark. A plurality of high-intensity LED's producing a total of at least 6 candelas when energized are surrounded by a striated refracting lens, the axes of the intense light cones being oriented between 20 and 40 degrees above the horizontal plane and impinging on the striations. The LED's are periodically and simultaneously energized.

Abstract: In an accumulator in a warping process, a plurality of tension sensors are mounted on a common support member such that adjustment of the support member simultaneously adjusts the release tension of all the tension sensors.

Abstract: A container for dispensing and storing carbonated beverages, having an outer rigid bottle and an inner collapsible non-elastomeric pouch. A valve mechanism admit air to an air space between the outer bottle and the inner pouch when liquid is dispensed, and seals the air space when the bottle is closed.

Abstract: An adapter assembly for the New Process Model 203 transfer case for four-wheel drive vehicles. The adapter assembly includes a first disc member mountable on the front surface of the forward wall of the principal housing. The first disc comprises a rearwardly extending bearing housing in the plane of the forward wall replacing the original forward bearing for the transfer shaft. A replacement bearing is mounted within the bearing housing on a new axis parallel to and displaced from the original axis of the transfer shaft, permitting continued usage of the chain after the chain would have to have been replaced according to prior practice.

Abstract: An improved partially-oriented nylon 66 (PON) spinning process and product are provided by increasing the molecular weight well above the levels customary for apparel end uses.

Abstract: A restraining block engages the valve stem of a safety valve, holding the valve open. The block is selectively rotatable within an auxiliary housing from a locked to a released position wherein both block and stem are free to move along the stem axis, permitting the valve to close.

Abstract: A rigid frame attachment for resisting tampering with an electrical meter. Angle irons enframe the meter face, with frame portions extending rearwardly along a lateral wall of the meter housing to rear frame portions engaging the rear wall of the housing. The front of the frame is attached, as by a lock, to the meter front wall at a point spaced from the side walls of the housing.

Abstract: A weftless warp of yarns being drawn and wound on a beam is fed through a tension detector, located prior to the drawing step and responsive to tension in any of the yarns equalling a predetermined non-zero level, for stopping the process. This prevents damage to or breakage of a yarn which might have become snagged in the warp source.

Abstract: Random doffing of a multiple-position winding machine is permitted by beginning yarn package formation at a high mean yarn traverse frequency provided by a first inverter, then shifting to a low mean modulated traverse frequency provided by a second inverter for further package formation. The output frequencies of the two inverters are controlled to be substantially identical at the time of transfer.

Abstract: A multi-filament splittable conjugate yarn wherein the filaments have the same denier and are splittable into different numbers of sub-filaments.

Abstract: In monitoring of yarn finish levels by conductivity, the yarn is grounded prior to the measurement, thus eliminating the effect of static electricity.
