Abstract: A tamper proof security door track and position means such as a door closer or door position indicator wherein the track is fully enclosed in the door closed position and protected by a slide closure in the open position to prevent debris from entering the track.

Abstract: A fastener particularly adapted for securing an end of a cord in an opening in an object comprises a cylindrical shaped body. Extending through the fastener body is a passageway to hold an end of the cord, for example. In practice, the fastener preferably is made of plastic allowing the fastener to be molded onto the cord. Projecting outwardly on an angle from an inner end of the fastener body is an ear. Because the cord, the fastener ear, or both are flexible, the fastener ear and cord may be pressed into alignment. Once aligned, the fastener and cord end may be threaded through the opening in the object with the ear then returning to its prior nonaligned position. The cord is prohibited from being drawn back through the opening by an interference fit between the fastener ear and the object.

Abstract: A fishing rod holder is disclosed, the primary members of which are a wedge shaped base and a holding tube including a flange. When utilizing two rod holders, one wedge shaped base can be inverted. This allows two rod holders to be used on one side of a boat without the lines interfering with each other. An arcuate slot is provided on the wedge shaped base which allows the rod holder to assume the same positions whether mounted with the wedge shape angled up or down.

Abstract: The invention provides a device useful for measuring water temperature at a certain depth. The device includes a temperature sensing part embedded in an insulating matrix part which provides a useful heat flow pattern. After being exposed to water of a certain temperature the temperature sensing part wil thermally equilibrate to that temperature after a period of time. The device will then hold this temperature reading even while being briefly exposed to mediums of different temperatures, such as exposing the device to air or water of varying temperature, and will allow accurate readings of the original temperature. The device appears to exploit the difference in thermal conductivities of air versus other media, such as water or slurries.

Abstract: A technique is disclosed for achieving reduced residues on a circuit board (10) following soldering of each conductive member (18) of a component (20) to each corresponding metallized area (12) on the board. At the outset, a layer (22) of low solids solder paste is applied to the metallized areas (12) on the board. Thereafter, an acid is applied to the paste layers (22). Finally, the low solids paste is reflowed while the circuit board (10) is immersed in the inert atmosphere to bond the conductive members (18) of the component (20) to the metallized areas (12) on the circuit board (10).

Abstract: A caster with an installation base comprises a shaft to be secured to a leg or bottom of a machine or instrument, a frame rotatably mounted on the shaft, movement wheels supported on the frame, an installation base arranged unrotatably and vertically movable on the frame, and a handle member for vertically moving the installation base. The frame comprises a connecting portion rotatably mounted on the shaft and an axle supporting portion for supporting an axle of the movement wheels. The installation base comprises a first portion arranged in the periphery of the connecting portion of the frame and formed in the outer peripheral surface with an external thread and a second portion positioned below the shaft to come into contact with an installation surface.

Abstract: Two parts of a case hinge are detachably interconnected, i.e. the hinge pin of one part and the hollow cylinder of the other part can be disengaged by axial displacement. Moreover, the hinge pin is rotatably and axially displaceably mounted on the associated hinge part and is pretensioned in an axially resilient manner. It is provided on its free end with a rotation preventer, which engages in non-rotary and axially detachable manner with the other hinge part. On opening and closing the case the hinge pin consequently necessarily performs a rotary movement. In its bearing-side portion, the hinge pin is provided with a radial stop pin, which locks in a bearing-side indentation under a predetermined angle as a result of spring tension and consequently detachably secures the two hinge parts under a predetermined opening angle.

Abstract: A toilet seat handle assembly which may be readily and easily repositioned on toilet seats of a large range of widths without tools is described. The assembly has two facing clamps spanned by a bolt. The bolt threads into one of the clamps, but passes through the other clamp in such a manner that it slides upon the middle of the bolt. A handle threads onto the opposite end of the bolt, such that the second clamp slides over the bolt between the first clamp and the handle. With the clamps in position on the underside of a conventional toilet seat, bridging the inner and outer margins of one side of the seat ring, the handle may be conventionally rotated to tighten the clamps to affix the assembly. Thus, the handle serves the dual purpose of the installing and removal mechanism, as well as the handle for raising and lowering the toilet seat without the need for touching the seat itself.
