Abstract: The invention includes improvements to a security holster including protective ridges for use around the release mechanism and the locking mechanism. Also included is a mortise and tenon arrangement for securing the holster body to a belt attachment plate.

Abstract: A prefabricated roof truss which includes a bottom plate which attaches to the bottom chord of the roof truss in such a way that the bottom plate does not lift away from the top plate of an interior wall despite the vertical movement of the bottom chord of the roof truss.

Abstract: A pivoting frame assembly for use with a pitching machine. The pitching machine for pitching balls. The pivoting frame assembly for supporting the pitching machine above a ground surface. The pivoting frame assembly having a first portion for supporting the pitching machine and a second portion configured for contacting a ground surface, these first and second portions pivotally connected to one another.

Abstract: The bird decoy, which expands into a fully three dimensional figure of a bird and may be compressed into a flat or nearly flat package. The decoy body is hollow and covers a coiled spring which may expand to display the three dimensional body of the bird and which can be compressed into a flat storage configuration. The coiled spring is covered by a fabric bird body, which has a head, tail, coloration and features all resembling a bird.

Abstract: An animal stanchion having fixed stanchion structure and a pivotal release stanchion laterally spaced apart to define a head opening. The animal stanchion further comprises an upper top control rail which is configured to interact with a latch to selectively hold and release various portions of the pivot rod from connection with the latch. This device further comprises a plurality of individual locking brackets which are configured to interact with handle catch devices so as to hold various devices within their designated location within the device.

Abstract: The invention is BURROWING PEST CONTROL DEVICE, while mixing together oxygen and a flammable gas and injecting it into an underground burrow. The device includes the feature of being operated from a remote position, a vortex injection of the gases, and a device for generating a shockwave to propagate combustion throughout the stream of mixed gases.

Abstract: A rudder mechanism for use upon a sailboat is capable of being raised or lowered at the discretion of the boater using a single connected cable operating system, so that the system may be called a “one-pull” system for both raising and for lowering the rudder. The rudder is preferably pivotal, using the cable operating system, greater than 90 degrees, and more preferably, about 180 degrees. A self-contained gas cylinder may aid in the raising and lowering operation and to dampen and smooth the vertical, pivotal movement of the rudder. The cylinder also may be utilized to retain the rudder in a raised or lowered position, once the boater/sailor has purposely placed the rudder in that position, and to return the rudder to the fully-lowered position after grounding has temporarily “kicked-up” the rudder.

Abstract: A cable handling device for use in the deployment and/or retrieval of a cable comprises a drum which provides mounting for a number of grooved rings, the rings receiving a cable thereabout. The drum forms an inner bearing race with each ring forming an outer bearing race such that the rings are independently and rotatably coupled to the drum. A second drum having one or more grooved ring is provided and the cable can be wound around the first and second drums. In use, one or both of the drums is rotated and the device is adapted to control the tension in the cable and/or to mitigate distortion in the cable caused by slippage between the cable and the device.

Abstract: A system for directly connecting multiple printed circuit boards (PCB) circuits without the need for peripheral connectors. Multiple PCBs are electrically and mechanically interfaced with one or more plated holes or tabs on at least one first PCB and one or more plated tabs or holes on at least one second PCB. The plated tab(s)/hole(s) from said second PCB mate with the corresponding plated tab(s)/hole(s) from said first PCB to form a mechanical and electrical interconnect.

Abstract: An ergonomic duty belt having a pliable outer covering, a semi-rigid frame member configured to form a semi-conically shaped section when placed about the waist of a user and to conform to the shape of a user's body. This semi conical shape provides for increased ergonomic comfort and decreased pain and discomfort to the wearer of the belt. This duty belt also has an accessory attachment system comprised of generally horizontally extending track portions as well as generally vertically oriented vertical plates. A variety of attachments having attachment portions configured to attach to the track sections and to these vertically oriented plates as well as to a traditional duty belt connect accessories to the duty belt.

Abstract: The invention is a window safety harness which can be clamped to the frame of a window and which provides a solid anchor point for a person working around the window. The device includes a bar for placement inside the window, a bar for placement outside the window, and a connecting piece which holds the bars in rigid, spaced apart relation to each other. Each end of both the inside and the outside bar have contact pads which are configured to contact the window frame. They also include a tightening mechanism which tightens the contact pads against the window frame and secures the device in the window frame. An anchor point allows a worker to attach himself to the anchor point for work outside the window, or to anchor a line to the window frame.

Abstract: Disclosed is a laser guidance system for diamond wire stone cutting apparatus. The laser guidance system includes a targeting laser light source that is fitted to one of two wire guide wheels between which the cutting wire extends and travels. A photo sensor with laser beam detectors is attached to the other wire guide wheel. During ideal operation of the cutting apparatus, the laser beam shines through the kerf in the stone being cut. When the kerf is linearly straight, as intended, the laser beam will be clearly detected by the laser beam detectors. When the kerf is not straight, the laser beam will be at least partially obscured across the cutting span, and the laser beam detectors will detect the lack of full intensity and report this to a controller so as to indicate that adjustments are necessary to re-straighten the kerf.

Abstract: A double-acting jar comprises an inner mandrel and an outer housing. The inner mandrel is disposed telescopically within the outer housing to define a fluid chamber in between. There is an uphole restriction and a downhole restriction spaced from one another within the fluid chamber. An uphole valve is disposed within the fluid chamber, the uphole valve having a first seating surface engageable with an uphole facing sealing shoulder in the fluid chamber. There is a downhole valve disposed within the fluid chamber, the downhole valve having a second seating surface engageable with a downhole facing sealing shoulder in the fluid chamber.
