Abstract: A portable contact lens and fluid storage kit comprising a generally conventional lens case adapted to receive a quick-detachable key ring attachment device so that the case may be carried with a set of keys or similar object worn or carried about a person in a convenient and hard to forget fashion. The key chain attachment device is easily detached so that the case may be separated from the keys and rested on a flat surface during contact lens insertion and removal.

Abstract: A crimp on flange tool of the type used to crimp door seals to vehicle door frames, comprising a handheld tool connected by a flexible drive coupling to a remote, separate drive unit whose weight is not added to the weight of the handheld tool when used by a human operator. The invention further includes a novel operator handle arrangement for the handheld tool, in which a handle is on-axis with the crimping rollers. Another aspect of the invention is a novel roller arrangement comprising two sets of parallel rollers, with a first set being spaced more widely to function as guide rollers and a second, downstream set being spaced more narrowly to crimp a seal fed to them by the guide rollers.

Abstract: An eyelet terminal for use in a vehicle junction box or power center to connect a bus bar to an electrical wire or cable. The terminal assembly is formed as a flat metal blank with bendable portions defining a nut-trapping lock ring, an anti-rotation tab, and wire crimping tabs. One end of the terminal includes an eyelet portion having an aperture for a bolt or threaded stud, and a surface for rotatably supporting a flanged nut over the aperture. The lock ring is formed at the end of a leg or arm extending from the eyelet portion and adapted to be bent over a radius to a nut-trapping position over the nut flange and aligned with the eyelet portion. A bendable anti-rotation tab extending from the lock ring is bent from an initial flat position to a right-angled position in which it extends through a suitable aperture in the terminal when the lock ring is in the nut-trapping position.

Abstract: A spring contact for a female wire harness terminal, the spring contact having a sacrificial ramp which a mating terminal wipes on insertion. The sacrificial ramp includes an aperture below which a failsafe contact connected to a spring portion of the ramp rests until the mating terminal nears full insertion, at which point the spring portion forces the failsafe contact upwardly through the aperture into electrical engagement with the mated terminal. The ramp bears the brunt of the sacrificial wiping; the failsafe contact remains out of wiping contact with the mating terminal until a point at or near the end of terminal insertion, thereby preserving the mating conductive portions of the failsafe leg and the mating terminal from sacrificial wear. This protected, end-of-insertion failsafe connection allows the female spring contact to maintain good electrical connection with the mating terminal over many cycles in high cycle applications.

Abstract: A watthour meter mounting apparatus, such as a socket, socket adapter and the like, has a safety shield completely enclosing the jaw contacts of the apparatus. Slots are formed in the safety shield to allow the insertion of a watthour meter blade terminal therethrough into connection with the jaw contacts. In one embodiment, a socket adapter housing includes front and back plates which are joined together and form a cavity therebetween in which the jaw terminals and the electrical conductors are disposed. Raised receptacles formed in the first plate loosely receive the jaw contacts mounted on one end of the conductors. In another embodiment, an insulating housing is mounted over the jaw contacts in a socket or socket adapter, with slots formed in the housing to allow the insertion of a watthour meter blade terminal therethrough into a jaw contact disposed within the housing.

Abstract: A probe holder non-rotatingly mountable in a support bracket releasibly receives a scanning microscope probe. Guide rods extend outward from the probe holder on the scan head and engage bores formed in the other of the probe holder and the scan head during closure of the scan head with the probe holder to co-axially align the probe with a probe receiver in the scan head. Transversely extending arms on a spindle attached to a scan head slide along ramp surfaces in the scan head to a fixed stop to rotationally position the scan head. Complementary surfaces on the spindle and a stationarily affixed sleeve co-axially center the scan head with the scan head support structure and the probe holder. A method of co-axially and rotationally aligning a probe for exchange between a scan head and a probe holder is disclosed using the guide rods and guide bores, the spindle arms, ramp and stop surfaces and the complementary surfaces on the spindle and the stationary sleeve, and a non-rotatable probe holder mount.

Abstract: A close loop thermoplastic recycling process includes the step of testing particulated processed plastic material to determine the properties thereof. The tested properties are compared with targeted near virgin properties of the processed plastic material to determine any difference(s) therebetween. Additives based on the property differences determined during testing are admixed with the particulates in a twin screw extruder. During extruding, volatile constituents are simultaneously withdrawn from the fused particulates. The twin screws of the extruder are provided with a number of screw sections, each having a thread with predetermined degrees of chamfer and pitch length. Kneading blocks are mounted on certain screw sections prior to a vacuum vent port disposed along the feed path of the melt stream in the extruder. The extruded material is tested to determine if any property differences exist.

Abstract: A polycrystalline compact cutting element for use in operations that require high impact and abrasion resistance. The compact includes a substrate formed of tungsten carbide or other hard material with a diamond or cubic boron nitride layer bonded to a mounting surface on the substrate. The interface between the layers is defined by a three-dimensional topography formed with a plurality of surface irregularities in an arrangement whereby a straight line or a constant radii accurate line does not connect a series of adjacent surface irregularities.

Abstract: An iceboat includes a hull and a perpendicular extending plank attached to the rear end of the hull. Side struts extend from outer ends of the plank to the forward portion of the hull. A mast is mounted on each side strut at a position rearward of the occupant cockpit in the hull and supports a sail. Skates are attached to the front end of the hull and to the outer ends of the plank.
