Abstract: An on-demand replay (“ODR”) system comprises a plurality of devices configured for automatically merging multi-angle video clips of an event. The devices can be configured to remotely start and stop recording of an event by a plurality of connected video cameras. Merged video clips may be transferred to a portable computing device.

Abstract: A training halter has a nose loop configured to encircle the nose of a horse, a head loop configured to encircle the head of the horse from the poll to the chin groove and a right strap, a left strap, and a chin strap that connect the nose loop and the head loop. A preferred embodiment of the training halter has a selectably removable band of multiple pressure protrusions positioned to apply pressure to a horse's nose and/or poll when the halter is pulled down and/or backward. A training halter having a nose loop with pressure protrusions and/or a head loop with pressure protrusions is more effective for training a horse not to pull away from a post.

Abstract: Embodiments of the present invention include a flexible rope insert having an elasticized central portion that is capable of stretching. This stretchable rope insert allows for limited stretching of the rope when an animal is roped. The flexible rope insert cushions the shock load on a steer or other animal that is stopped too abruptly with a rope.

Abstract: A mechanical gate opener is used to activate an opening mechanism for a livestock chute. The gate opener includes a weight, an elevating mechanism for lifting the weight to a set height, and a delay mechanism for extending the time from when the weight is released from the set height to when the weight strikes an actuator for the gate opening mechanism. One embodiment of the gate opener includes a diverter for diverting the released weight to prevent the weight from striking the actuator and initiating the gate opening.

Abstract: A simple flexible coiled tubing connector couples the ends of two separate sections of tubing so that mutual axial tensile forces can be transferred between the two sections. The tubing connector is intended for use with tubing which may be coiled on a storage reel and freely run through a coiled tubing straightener or tensioning device. The tubing connector is not required to contain pressure, transfer compressive axial loads, torsion, or loads transverse to the axes of the tubes.

Abstract: A livestock chute insert that adapts a livestock chute for use with smaller livestock. One embodiment of the insert reversibly modifies existing gated livestock chutes to prevent smaller livestock from turning around in the chute or jumping up and hurting themselves.

Abstract: One embodiment of a remotely controlled apparatus for selectably admitting a large animal into and then selectably releasing the animal from a livestock chute uses the weight of the animal as its primary energy source for opening and closing the entry and exit gates. The livestock chute has a linking mechanism for communicating with the entry gate, the exit gate, a moveable floor, and a biasing force wherein the weight of the animal is used to overcome the biasing force to open the entry gate and to store energy that can be selectively activated to open the exit gate on the livestock chute.

Abstract: A simple mechanical height adjustment device adjusts the ground clearance of a trailer. The trailer, having the height adjustment device can selectably and reversibly increase its ground clearance. The trailer, having an adjustable ground clearance, can minimize its load height when operating on improved roads in order to meet local and state height regulation, but can increase its ground clearance on uneven roads.

Abstract: A mobile coiled tubing rig for the drilling and workover of wells is designed to have a control room for the coiled tubing rig positioned within a tank at the forward end of the rig during transport. The control room, stored in the empty tank during transit, is selectably elevated out of the tank to its working position during rig operation. When the control room is elevated, the operator or operators of the coiled tubing rig can see the coiled tubing storage wheel and the coiled tubing injector.

Abstract: A selectably elevatable coiled tubing injector is described that is suitable for a mobile self-contained unitized coil tubing rig for the drilling and workover of petroleum wells. The selectably elevatable coiled tubing injector includes a mechanism for positioning a trailer mounted coiled tubing injector either in a first stowed position on the deck of the transport trailer or in a second position resting on an elevated rig floor of a drilling rig. Furthermore, the selectably elevatable coiled tubing injector includes a further mechanism for selectably elevating the injector above its second position on the rig floor while clamping the tubing in order to provide additional tension on the tubing string or to raise the tubing deployed within a well.

Abstract: A device for applying tension to a string of coiled tubing for the purpose of its insertion into or withdrawal from a wellbore. Specifically, the device is used with a wheel-type tensioner, which contacts and supports the tubing over an arc length of less than 180°. The device enhances the tractive ability of the tensioner by applying forces normal to the tubing to press it into more intimate contact with the surface of the wheel, thereby increasing the normal force and attendant frictional force between the tubing and the wheel.

Abstract: The invention contemplates a selectably operable hydraulic means for laterally shifting one end of a non-moving vehicle in order to provide a desired alignment. The present invention is particularly applicable to vehicle-mounted equipment which has an invariant lateral mounting position on the vehicle and which must be laterally aligned with a stationary workpiece axis. An example of such a need occurs with mobile workover rigs used in well maintenance.
