Abstract: JET VELOCITY MEASURING  APPARATUS                  ABSTRACT OF THE DISCLOSURE      A jet velocity measuring apparatus is disclosed for measuring the velocity of a fluid stream.  The apparatus (10) measures the time delay between primary electronic signals generated by a first photosensitive device (32) is a result of a first beam of light from a light source (34) being re-flected by a portion of the surface (S) of the stream (24) and secondary electronic signals generated by a second photo-sensitive device (36) as a result of a second beam of light from a light source (38) being reflected downstream by sub-stantailly the same portion of the surface of the stream (24).          The apparatus includes a housing (22) disposed parallel to the plane (P2) of the surface of the stream.  A first and a second fiberoptic bundle (42, 44) transmit light from the light source (34, 38) to the surface of the stream (24) and back respectively to the photosensitive devices (32, 36).          Debris-deflecting slots (88, 90) are disposed adjacent to the housing (22) for deflecting debris therefrom.

Title: Method and means of skinning meat
Inventor: TOWNSEND RAY T
IPC: A22C25/17
Filed: 1987-01-19
Granted: 1991-07-02
Abstract: ABSTRACT OF THE INVENTION    A meat skinning machine is disclosed including a frame, a meat supporting surface on the frame, and a powered cylindrical gripping roll with a plurality of teeth on the outer surface rotatably mounted on the frame.  A blade holding device is mounted adjacent the gripping roll and maintains a cutting blade closely adjacent the teeth of the gripping roll.   A shelf device is mounted on the machine between the meat supporting surface and the cutting edge of the blade just-beyond the periphery of the teeth of the gripping roll.   The shelf device of a first embodiment comprises a skin stripping element having a base portion and an arcuate open hook portion having a peripheral edge with the hook portion being received into an annular groove cut in the gripping roll.  A meat supporting edge extends radially beyond the outer surface of the hook portion.  The shelf device is created when a plurality of the stripper elements are placed in a plurality of annular grooves in the gripper roll.  Adjustment means interconnect the frame and the stripper elements to adjust the distance between the blade and the meat supporting edges.   A first alternate form of the shelf means comprises an elongated member dwelling in the space between the meat support ing surface and the cutting blade.  A plurality of fingers extend from the elongated member, with the lower portions thereof dwelling in annular grooves in the gripping roll and the upper portions extending beyond the periphery of the gripping roll to create a meat supporting surface.   A second alternate form of the invention involves a similar elongated member with either protruding fingers or of solid construction but which completely extends over the periphery of the gripping roll to permit the gripping roll to be of continuous construction.    A method of skinning meat is disclosed comprising the supporting of the meat product immediately adjacent the cutting edge of the blade at a position radially beyond the periphery of the gripping roll to support the meat product until just prior to the time that the meat product moves into contact with the cutting edge to permit the meat product to move in an angular direction towards the gripping roll and into contact with the cutting edge to permit the blade to separate the membrane from the meat product.  The separated membrane will then engage the teeth and be pulled away from the cutting edge by the teeth in a path between the cutting blade and the teeth.

Title: Low energy, low water consumption warewasher
Inventor: NOREN TORE H
IPC: A47L15/00
Filed: 1987-01-30
Granted: 1992-02-04
Abstract: Docket HMS 005 P2 Abstract of the Disclosure A commercial warewasher is disclosed, in which racks of soiled ware, such as dishes, are consecutively washed through a machine cycle which includes recirculating wash water over the ware followed by a fresh water spray rinse.  A portion of the wash water is drained and a second portion is retained in the machine after each rack of dishes is washed, and combined with subsequent fresh rinse water spray to provide a volume of water sufficient for pumped wash recirculation for the next rack without cavitation.        When a drain valve is opened, water pressure to the wash arm system is reduced, flow through it decreases, and when the pump stops the wash system will drain by gravity to the lowest point in the wash system plumbing.          In the meantime the pump discharges wash water until the level of water in the sump and/or its associated outlet pipe reaches the level of the pump impeller eye.  The pump begins to cavitate and effectively ceases to pump water.        The pump and its drive motor are mounted outside the perimeter of the cabinet, with the pump impeller inverted and the drive motor extending vertically above the pump.  This, together with the plumbing lines being located adjacent the bottom wall of the cabinet, leaves a substantial open space between the supporting floor and the underside of the machine, providing for ease of cleaning and maintenance in a crowded kitchen environment.

Granted: 1993-03-30
Abstract: ABSTRACT         A METHOD OF DISINFECTING HARD SURFACES      Hard surfaces are disinfected using alcoholic microbiocidal compositions which contain reduced alcohol and anti-microbial concentrations.  The compositions comprise an aqueous solution of a lower alcohol, an acid and an anti-microbially effective amount of an amino- or ammonium- based microbiocide, the pH of the total composition not exceeding 5.  The reduced alcohol and microbiocide levels improve safety of handling and suitability for use on surfaces which contact food.  The compositions demonstrate both disinfectant and preservative properties.

Title: Steerable keel
Inventor: COHEN DANIEL L
IPC: B63B41/00
Filed: 1987-03-10
Granted: 1991-10-29
Abstract: A STEERABLE KEEL                  ABSTRACT     A steerable keel (10) comprising, in a first embodiment, a stationary section (12) and a rotatable section (14) and in a second embodiment, a stationary section (30) and two rotatable sections (32)  (34).  In either embodiment, the steerable keel (10) is designed with an aerodynamic fin cross-section and extends downwardly in a vertical direction from the hull of a sail boat (50).  The rotatable sections (12) or (32) (34) are in independently controlled by a tiller(s) located above the boat deck.  The keel (10) in operation is fixed.  However, a means is provided to retract the keel to allow the boat to dock and navigate through shallow waters.  The steerable keel (10) is designed to equalize the wind force and its below water keel counter force by providing a controlled below water lifting force that is produced by selectively adjusting the arc travel of the rotatable keel(s).  Thus, the boat beam is maintained in a relatively horizontal plane which, in turn, allows a greater speed to be achieved.
