Abstract: Disclosed are methods of repartitioning nutrients in ruminants. Serum concentrations of serum insulin, serum urea nitrogen, serum glucose, and serum growth hormone in ruminants were varied by feeding specific protein supplements and an otherwise negative energy diet. Improvement in body condition and body weight was concomitant with reduced milk production and calf weight.

Abstract: A heat sink and retainer clip for use in conjunction with an electronic integrated circuit, such as a semiconductor device, to provide cooling of the device, the device being mounted on a rectangular socket with opposing sidewalls and at least two of the sidewalls having lugs projecting laterally outward. The heat sink has a flat plate and a plurality of fins projecting upward from the top surface, except over the central portion of the plate. The retainer clip is constructed of two pieces. One piece is an elongated strap having a bent portion that bears down on the heat sink to force it into a heat conducting relationship with the device and also includes an opening that is hooked on the one of the lugs. The strap lies in the central portion of the sink. The second piece is rotatably mounted on the end of the first piece and when forced down and rotated inward, an opening will hook on the other lug.

Abstract: A lockout device to prevent tampering with the manually set position of a valve or regulator or other device having a rotatable shaft for adjusting, for example, the flow of fluid through the device, from a position initially set to some other position. The lockout device is usable with a wide range of standard valves and regulators which have a drive stem and includes a drive gear that engages the drive stem and a key locking device mounted in a generally cylindrical handle of the lockout device and being selectively movable from a first position in which the handle free-wheels relative to the drive stem of the valve so as to prevent unauthorized moving of the rotational position of the valve stem by any person not having a key to an engaging position in which the handle is locked to the drive stem to permit ordinary rotational movement and setting of the valve stem position.

Abstract: A message or note board that is also a holder for mail constructed of recycled plastic material and assembled from several different types of plastic but easily disassembled with common hand tools so that after final use, the parts may be segregated for further recycling. The noteboard has a flat plastic backing or plate that can be attached to a wall or a door on a refrigerator. Attached to the front surface is a transparent sheet that can be written on with a dry-erasable pen. A sheet of paper may be inserted between the transparent sheet and the backing plate and contains information. The lower end of the plate has an L-shaped tray or ledge that supports mail.

Abstract: A method and the apparatus (hereinafter referred to as the environmental monitoring system or EMS") designed to sample, detect, measure, and report, in real time, the presence of contaminants and thereby provide users with the ability to continually monitor conformance of water with established health and safety standards. When integrated with a user operated process control system, the EMS enables users to control the monitored process and to thereby ensure that the sampled water complies with established health and safety standards.

Abstract: A temporary barrier system particularly adapted for use in or around a home in which children who are learning to walk are provided with wheeled vehicles that may be propelled by the child and run or bumped into furniture or other valuable objects. The protection system includes two elements: an elongated bar and a stanchion or supporting member. The stanchions are provided with some means for resisting movement from the position in which they are initially placed. The stanchion has a plurality of openings or slots which are designed to support the ends of the elongated bars. At least two of the openings are perpendicular to one another; others are formed at acute angles to the perpendicularly disposed openings. The cross section of the slot and the elongated bar are designed so that the bar fits tightly in the slot providing some rigidity to the assembly. By placing elongated members of different length in slots at different angles, a variety of shapes may be formed.

Abstract: An improvement in a magnetic tape playback apparatus for determining the location of any portion of the magnetic tape as it passes the tape reading head including optically readable indicia means printed on the magnetic tape representing encoded information and means for optically reading the indicia including a light source and detector both mounted on one side of the tape. The improvement is compatible with existing magnetic tape playback devices and magnetic tape cassettes.

Abstract: A hydraulically operated toothbrush in which the flow of water from a faucet through the toothbrush handle and into the head produces rotation of a plurality of bristles mounted in the head, the bristles also being mounted for limited axially movement, and including a device for regulating the water pressure within the head to thereby assure the proper rotation of the bristles. The toothbrush may also include a siphoning tube operated by the suction created when water passes into the toothbrush, one end of the tube being inserted into the user's mouth and the other in a discharge basin. The siphoning tube may also be fitted with a mouth rinse fluid cup to introduce small amounts of fluid into the user's mouth during the brushing.
