Abstract: A device for insuring that the striking surface of a sports implement is properly oriented prior to the initiation and completion of a contact swing. Two position orientation sensors are affixed to the shaft of the sports implement. One sensor senses the roll position of the striking surface, and the second sensor senses the pitch position of the striking surface. When both of these sensors indicate that the striking surface is properly oriented, an audible signal is generated. This signal is maintained for as long as the striking surface is properly oriented.

Abstract: A method of controlling the aging or maturing of edible material such as meats, fish, dairy products, cereals, etc. by keeping the edible material in the presence of a freezing point depressing agent and an extract from the edible material at a temperature ranging from 0.degree. C. to the freezing point of the material whereby the resultant flavor and/or taste of the edible material is improved.

Abstract: A detonator net weapon for use primarily in anti-submarine warfare. The weapon comprises spaced, interwoven alternating lengths of nylon rope and detonator cord, and the detonator cord is ignited by conventional battery-powered target contact detectors. Floats at the top of the net control the buoyancy of the net and thus regulate its rate of descent through the water. The net weapon is stored in a compact container, and may be deployed from an airplane or from a ship into the path of a submarine, hydrofoil, torpedo, missile, or the like. The detonator cord, upon ignition, will explode with sufficient force to damage any object in contact thereof. The detonator net weapon is versatile and may be used against special types of surface ships, torpedoes, etc., and may, with minor revisions, be used in land warfare against tanks and infantry. In addition, the net weapon may be configured for use against anti-armor and/or sea-skimmer missiles.

Abstract: A solar-powered beacon comprises a water-tight caisson housing a battery for storing electricity produced by solar cells atop the beacon.

Abstract: A combination slicing and storing device for food products in block form wherein the food product is caused to descend by gravity within a tubular member mounted on a base such that a portion of the food product projects through an opening in the base and is supported on a recessed food support provided on a slice holder plate. The slice holder plate is operatively associated with a trigger member mounted on the base, being adapted for sliding movement with respect to the base upon manual actuation of the trigger member by a user of the device. Actuation of the trigger member causes a cutting member on the slice holder plate to be drawn through the projecting portion of food so as to create a slice of food product of uniform thickness. The slice is allowed to fall away from the device and onto a serving dish or plate by virtue of the fact that the food support has moved out of position beneath the food product.

Abstract: A child resistant dispensing closure of the type having a cap and a spout mounted thereon for rotation about a substantially horizontal axis. The upper surface of the cap is provided with a pattern of ribs. The upper surface of the spout is provided with a plurality of ribs, each of which has a distinct energy plane. All but one of the energy planes fails to allow sufficient purchase on their respective ribs and fails to produce the proper force vector required in order to initiate rotation of the spout when a manual force is applied to the latter energy planes. Only one of the energy planes is adapted so as to allow sufficient purchase and to produce the proper force vector required in order to initiate rotation of the spout when a manual force is applied to said one plane.
