Abstract: This invention is a blade guide to allow the angle that the blade addresses a sharpening rod to be repeatedly and accurately re-established. This is accomplished through the provision of a guide plate outwardly projecting from the sharpening rod with a guide arm thereon. When the blade is placed with the back of the blade at the juncture between the guide plate and the guide arm, and the cutting edge of the blade against the sharpening rod the angle the blade addresses the sharpener can repeatedly be re-established before each sharpening stroke of such blade against the sharpener. Once this correct angle is established, it can be maintained even through the blade is no longer engaged with the guide. By making the guide arms adjustable longitudinally along the guide plate, the optimum angle can be set for an infinite number of different sizes of blades. Also indicia is provided on the guide plate so that the proper location of the guide arm can be readily determined by reference to such indicia.

Abstract: This invention is a relatively simple and yet highly efficient disabling mine that is approximately the size of a tube of lip balm or a 20 gauge shotgun shell. A detonator and its associated detonator pin is adapted to fire a detonator cap in the end of a charge chamber. The charge chamber is filled with magnesium except for the area immediately adjacent the detonator cap which is gunpowder that is used as a magnesium igniter. When the mine of the present invention is ignited, it will burn fiercely at a temperature in excess of 3000 Fahrenheit for a period of 5 to 6 seconds which will disable personnel as well as vehicles and other enemy equipment coming in contact therewith. Because of the relatively small size of the mines of the present invention, at least 50 of the same can be carried by a single soldier in a bandolier.

Abstract: An automatic controller utilizes a pulse oximeter signal to regulate the oxygen mixture output, peak expiratory end pressure, and inspiratory ventilation time from a positive pressure respiratory assist ventilator. The pulse oximeter senses a patient's hemoglobin saturation and pulse rate by an optical sensor to develop a signal which is used by calculator to determine the patient's corresponding partial pressure of arterial blood. The calculated partial pressure of arterial blood is then used by the calculator in determining the level of inspired oxygen, peak expiratory end pressure, and inspiratory ventilation time provided to the patient. The calculator generates a signal to control the level of inspired oxygen, expiratory end pressure, and inspiratory ventilation time output from a positive pressure respiratory assist ventilator.

Contrast material is provided at the apex of the arch and in each of the leg portions such that the x, y, and z axes can be shown in three-dimensional images of the patient.

Abstract: This invention is a combination pickup device and tine cleaner having an elongated sleeve with an actuating shaft mounted therein. A tine head is mounted on one end of the sleeve and a handle on the other end. A plurality of tines outwardly project from the tine head on the opposite side from the sleeve. A cleaning plate, with openings in axial alignment with the tines, is mounted on the end of the actuating shaft adjacent the tine head. An actuating knob is mounted on the opposite end of the shaft so that as debris is picked up by the tines, the plate will be pushed up adjacent to the tine head causing the actuating knob to move out of the sleeve adjacent the handle. By pushing on the knob, the shaft can be forced back into the sleeve adjacent the handle which will cause the cleaning plate to move down the tines to clean the same. A height adjustable handle provided in a modification. Also, a pin to lock the device with the tips of the tines covered by the cleaning plate is provided.

Abstract: This invention is a drop-lock adjustment used on automatic feeders to adjust the feed gates either up or down and includes shielded drop locks connected to control rods that pass through a channel. An adaptor plate mounted on the channel has a downwardly projecting flange spaced from the channel with an elongated slot in the plate to prevent the animals being fed from tripping the lock to cause either more or less feed to be dispensed.

Abstract: This invention relates to traffic control means for emergency-type vehicles including an on-board plotter screen having a diagram of streets, roads, highways and the like displayed thereon. A light pen is used to draw the preferred route which is then either accepted or rejected in part or as a whole by a computer based on a current street condition program. Once the route has been accepted a traffic signal map program can be activated that will automatically control traffic along the route to the destination of the emergency vehicle.
