Abstract: A latex article such as a glove or girdle having a halogenated outside surface to a first degree and a halogenated inside surface to a second degree thereby providing different slippery coefficient surfaces on the outside and the inside of the article without the need of powders, resins or exterior finishes.

Abstract: A positioner for holding and supporting an infant in either a prone or supine position consisting of a wedge having a first plane at a given angle of at least 30 degrees that is contiguous with a second plane having an angle that is less than the angle of the first plane. A bifurcated U-shaped member is located over the first plane and the extending tapered arms of the bifurcated U-shaped member contact both portions of the first plane and the second plane thereby preventing movement of the infant in a vertical direction or in a lateral direction while at the same time allowing the infant to move in a safe and unrestrained manner.

Abstract: A system and method for use in a supermarket utilizing code reading machine scanning equipment to verify compliance of coded redemption coupons and sale vouchers submitted by the public. All documents contain machine readable coded information defining the terms and conditions of redemption and a scanning verification system is provided that indicates directly to the checkout clerk and customer whether all coded conditions on the redemption coupon have been satisfied prior to approving the discount offered by the coupon.

Abstract: An improved cartridge magazine constructed of high impact nylon resin and in which a spring urged follower pushes cartridges into a rifle into which the casing is inserted. The follower is attached to the spring which prevents fore and aft movement of the follower and the spring is curved to physically contact the bottommost portion of the follower to prevent the follower from pivoting about the spring contact. A removable floor plate is removably attached to the casing by means of a pair of resilient latches. The floor plate is symmetrical and has no preferred orientation, thereby simplifying loading of the cartridges.

Abstract: This invention relates to a battery controlled vehicle having a long operating time between battery recharging cycles. The vehicle is hydraulically operated and controlled by means of a variable displacement control and at constant pressure. A battery operated driving motor mechanically drives the hydraulic pumps to maintain the constant pressure while the operator controls the variable displacement valves to control the functions of the vehicle. The life of the battery is extended by means of a hydraulically driven generator that continuously recharges the battery controlling the driving motor. The battery operated motor is always operating at full speed and hence the need for a controller is eliminated, thereby simplifying the electrical controls.

Abstract: Video information obtained in real time is clocked and digitized according to light intensity. Changing light intensities are adaptively determined to vary the threshold level for determining black and white signals. The scene to be used as a reference is first recorded in a fine format and then in a coarse format. In the search mode the coarse stored information is compared in real time with coarse information from the field of view and convolved to generate a correlation number indicating the percentage of match. The location coordinates in the X and Y dimension for the best match is determined at the location of the highest correlation number. A fine search is then made around the coarse location previously determined by convolving in two dimensions previously stored information against information in real time from the scene under investigation to again determine the highest correlation as a measure of the location where the best possible match can be determined.
