Abstract: DISPENSING NOZZLE                     Abstract of the Disclosure A two-piece nozzle for use on hand actuated pump dis-pensers is disclosed.  The nozzle features a tubular member, which may be a part of the main body of the pump, having a circular, planar face at its terminal end.  A hollow bore extending through the tubular member and the hollow face is in liquid passage com-munication with a recess in the planar face.  A cap is rotatably mounted to the tubular member and has an end wall with a planar inside surface which will form an interface with the circular planar face of the tubular member.   Radially displaced from the center axis of the circular skirt is a dispensing orifice which is registerable with the recess present in the planar face of the tubular member.  A sealing boss surrounds the dispensing orifice and bore to provide a liquid-tight seal with the planar face when the orifice is not in registration with the recess.  Mounting structure is provided on the cap and tubular member for achieving a rotating mount of the cap to the tubular member.

Abstract: TITLE High Efficiency Heater for Air or Water ABSTRACT OF THE DISCLOSURE A high efficiency heater for air or water is disclosed in which the combustion products from a flame are forced through water in a contacting device in a manner to transfer almost all of the useable heat of the combustion products to the water, and to heat the water to a temperature of about 120 to 185°F.  The cooled waste gases are vented to the atmosphere, and the heated water is passed through a heat exchanger to heat air or water such as for a home heating system.  As the heated water passed from the contacting device to the heat exchanger is at a temperature below the normal boiling point of water, a plastic heat exchanger can be used, which is low enough in cost to permit using a large unit for maximum heat utilization.

Abstract: ABSTRACT         A ring of cells for analytical devices operating on the centrifugal principle and photometrically measuring a sample for analysis, the system comprising a number of individual cells disposed in a circle and made of thermoplastics, each cell having three interconnected chambers, i.e. a sample chamber, a reagent chamber and a photometric measuring chamber, the major axes of the sample chamber and the reagent chamber being at right angles to the plane of rotation and the major axis of the measuring chamber coinciding with the plane of rotation. In order to simplify and thus reduce the cost of the ring of cells, each cell at its upper edge has a laterally projecting tongue which completely or partly overlaps the adjacent cell and is secured thereto.  The above ring of cells is primarily intended for use in a centrifugal analyser for clinical chemistry.

Abstract: FISH STICK CUTTING METHOD AND APPARATUS     Abstract of the Disclosure A number of pairs of frozen fish slabs are arranged vertically in an equal number of laterally spaced vertical tubes or chutes constituting a magazine, each tube or chute having a partition dividing it into two open-ended compart-ments with a slab being slidably contained in each compartment.          A cutter assembly comprising a blade carrier and a vertically adjustable table move as a unit at an acute angle beneath the magazine.  The carrier has fixedly mounted at another acute angle thereon a plurality of flat blades equal in number to the number of tubes or chutes, each blade having a knife edge ex-tending along opposite sides thereof so that when the cutter assembly is advanced in one direction the lower end of one of the slabs of each pair of slabs is severed and when retracted the lower end of the other of the slabs of each pair is severed to form individual fish sticks having a thickness de-termined by the distance the table is spaced below the plane in which the blades move.  Whereas the thickness of the fish sticks is determined by the height of the table, the length and width thereof are determined by the cross section of the frozen slabs.  The table has appropriately located openings therein so that the fish sticks gravitationally drop into angled troughs after they have been severed from the slabs.          The fish sticks are then pushed from the angled troughs onto a conveyer in a uniformly-oriented manner suitable for food processing operations, such as breading and battering.

Abstract: ANIMAL FEEDER            Abstract of the Disclosure An animal feeder is disclosed which comprises a feed trough and a hopper mounted above the trough for automatically feeding stored food into the feed trough as it is consumed by animals feeding therein.  Flow of food from the hopper into the feed trough is controlled by an agitator or butt plate located within the trough and spaced a predetermined distance from the bottom of the trough.  A wire grid extends from the butt plate upwardly into the hopper such that agitation or movement of the butt plate by animals feeding within the trough causes corres-ponding movement of the wire grid.  To control the flow of food from the hopper into the trough, the butt plate is adjust-able relative to the trough so as to vary the size of the opening through which the food must flow in order to become accessible to animals feeding in the trough.  This adjustment is effected by a pivoted lever which is controlled from a handle located in the open top of the hopper.

Title: Rotor thermal protection relay
Inventor: HAMILTON MALCOLM W

Granted: 1983-04-12
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a circuit for the protection of a dynamoelectric machine.  The device is particularly directed to the protection of a rotor from thermal overloads.  The circuit basically produces two signals; proportional to the positive sequence currents flowing in the rotor and the second proportional to the negative sequence currents flowing in the rotor.  These two signals are injected into solid state logic circuitry such that each signal is squared; the negative sequence signal multiplied by a proportionality constant; and the two signals are then summed and fed into a thermal analog device which provides an indication of the rotor temperature at any particular interval of time.  A level detector is supplied to the thermal analog device to sense the signal corresponding to the temperature of the rotor in the thermal analog device and when this signal is of a predetermined magnitude, corrective action may be taken to shut down or unload the dynamoelectric machine.

Abstract: ABSTRACT The device required to produce the desires effect of this invention idea consist of a stretch type spring, of appropriate size, with attaching brackets for each end.  Attached to the lower portion of a sectional overhead door supporting cable, in a prescribed manner, the device acts on a potential problem in an already installed, shaft operated door of this type.  It provides a secondary, opposing tension to a portion of the cable, which tension will, in effect, absorb potentially dangerous cable slack when it occurs.  The simplicity of the device provides for low cost, relatively easy installation and no requirement for lubrication.

Abstract: ABSTRACT OF THE DISCLOSURE       The actuation of a flow regulating valve at the intake side of a compressor and of a downstream blow-off valve is controlled by a pressure-operated controller so arranged that on increase of the post-compression pressure within a range below a threshold pressure opening the blow-off valve, the flow regulating valve reduces the flow of the medium to be compressed.  The controller operates with a first duct connected to the discharge end of the compressor, with a second duct disposed at the secution side but downstream of the regulating valve, and with an intermediate duct connecting the first two.          Flow constriction means at each end of the intermediate duct maintain the pressure at a level between the pre- and post-compression valve.  The arrangement provides a more consistent regulating behaviour than the known controllers whose operation is governed by the instant value of the discharge pressure resulting in the tendancy to over-control the operation in response to short-term pressure fluctuations.
