Abstract: An apparatus and methods for detection of estrus and optimal time for embryo transfer or artificial insemination in animals. An arched polycarbonate housing is attached to an animal. A circuit board is disposed within the housing. A rechargeable battery mounted on the circuit board provides power to the apparatus. A switch mounted on the circuit board is actuated when a breeding behavior occurs. A controller mounted on the circuit board detects actuations of the switch to generate data indicative of breeding behavior. A transmitter transmits data indicative of breeding behavior to a remote receiver.

Abstract: Apparatus and method for detecting when an animal is in heat is provided. The apparatus includes a logic controller, a power source, a clock, an actuator, and a presentation interface such as an array of LEDs (Light-Emitting Diodes) that records breeding behavior in animals and presents corresponding data in a manner that can readily be observed from a distance. The method includes, according to some embodiments, receiving a first stimulus, validating that the first stimulus was received incident to a first mating-behavior event, receiving a second stimulus incident to a second mating-behavior event; and storing the occurrence of the first stimulus along with a time indicator for future retrieval and display on a presentation interface, wherein the presentation interface includes an LED array.

Abstract: A multiple blade centrifugal cutting machine having a planetary gear system for coordinating the motion of the blades so that the blades move into the work at the same speed to an equal depth to either sever the work element or strip away one or more layers of coating from the core of the work element.

Abstract: A controlled release agricultural composition comprising an aqueous dispersion of: 1) a water insoluble matrix comprising a viscous oil (i.e., a hydrocarbon crude oil or post-refining residual oil) selected from the group consisting of bitumen, abietic acid, ester derivatives of abietic acid, carboxylic acid containing materials, and carboxylic acid ester containing materials, and 2) at least one active ingredient, which has a melting point of less than 140.degree. C. and is soluble in the viscous oil matrix, selected from the group consisting of herbicides, insecticides, fungicides, and nematicides.

Abstract: A process for preparing ferrous picrate comprising reacting picric acid in solution in a straight- or a branched-chain aliphatic alcohol with an iron carbonyl at a temperature between 10.degree. C. and 120.degree. C.

Abstract: A program-controlled knitting machine provides a method of knitting circular knit elasticized tubular goods, e.g., compressive stockings, in which the size of the goods and the amount of compression asserted when worn are controlled according to the specific size and needs of the individual using the goods.

Abstract: An improved support stocking exhibits a compression profile customized to the patient's needs and corresponding to a computer program determined profile.

Abstract: A drive is disclosed utilizing at least two units of which one may be an auxiliary. Each unit is positionable in a relatively deep body of water and has upper and lower sprockets about which a chain is trained which carries a series of receptacles that open in the trailing direction. The chain courses of the conveyors that are to travel upwardly are close together and air under pressure is delivered into the receptacles of at least one unit as they reach the lower end of its upwardly travelling course to render the receptacles of those courses buoyant. At least one receptacle of each unit is positioned to receive air escaping from or bypassing a receptacle of the other unit. At the upper end of the downwardly travelling courses, the receptacles become weighted as they fill with water.

Abstract: There is disclosed a motorized reclining chair. All motions are controlled by a single reversible motor, the cost of the motor being offset by the relatively low cost of the linkages which are employed. The chair offers numerous advantages, including: (1) leg-rest motion takes place without set/back motion until the leg rest is raised to an intermediate position, following which the leg rest and seat move together, (2) three-way operation, in which the back tilts relative to the seat, can be provided at minimum additional cost, simply by pivoting the back to the seat and adding a single link on each side of the chair, and (3) in moving to the fully reclined position, the entire seat rises, with the front edge rising more than the rear edge, as contrasted with prior art reclining chairs in which the rear of the seat drops down. The motive force is provided by an upwardly thrusting shaft controlled by the motor.
