Inventor: MCELROY PHILIP J R
IPC: A41D13/06
Filed: 1989-10-31
Granted: 1996-12-03
Abstract: A unique protective knee pad is disclosed which is comprised of one-piece molded resilient polyurethane foam. The pad has a special U-shaped sole with a transverse bar through the middle portion and a transverse bar at the rear. Two cavities are created by the transverse bars which are adapted to entrap air when the wearer is in the operative kneeling position thereby cushioning the delicate parts of the patella and upper shin, by preventing the outwardly extending portion of the knee from coming into contact with the ground.

Abstract: IMPROVED DRIVE AND SUPPORT FOR MIXER DRUM                 ABSTRACT OF THE DISCLOSURE      Certain improvements are provided to the mechanical aspects of a tilt mixer which  include a novel boggy,  adjustable  roller arrangement  on  the  drum  track  which  produces  an  improved distribution of the stresses produced by the extremely heavy rotating drum which reduces the wear on both individual rollers and on the track.   An unique dual staggered tooth gear drive  is provided having two spaced sets of teeth each addressed by a pair of motor shaft mounted drive gears on each of a pair of flanking motors in which the teeth of the two sets are staggered or offset by one-half of the gear pitch.  This produces a tighter, quieter drive wihch has been found to reduce gear wear. In addition, a unique torque tube system wihch possess a great deal more strength than previous drum tilt axles is provided to support the pivotal action of the drum thereby enabling the tilt point of the drum to be moved forward toward the discharge end of the mixers.  This, in turn, reduces the amount of clearance height necessary beneath the drum upon discharge of the drum contents.

Title: Voice recognition dialing unit
Inventor: SHIMADA KEIKO
IPC: H04M1/274
Filed: 1990-06-19
Granted: 1994-10-25
Abstract: ABSTRACT OF THE DISCLOSURE           A voice recognition dialing unit of a telephone mounted on a vehicle or similar mobile body and which allows a call to be originated with ease.  When the user of the telephone enters a voice command on a voice inputting section, the dialing unit originates a call automatically and thereby connects the other party to the telephone line. In a call origination procedure, the operations for call origination and verification are performed between the user and the unit in an interactive sequence.  In a preferred embodiment,  the unit has a particular call origination procedure in which, when the other party recognized by the unit  is  incorrect,  as  determined  by  the  user  by verification, lower-place candidates for the other party are called up in repones to a particular voice command.  In an alternative embodiment, the unit indicates the other party by uttering a name for verification purposes.  This alternative embodiment has means for selecting and storing only the name of the other party in response to an entered voice  signal  and,   in  the event  of  response  for verification, combining the name having been stored in this means and response information stored beforehand to produce a composite voice response.

Title: Apparatus for filleting fish
Inventor: EVERS REINHARD
IPC: A22C25/16
Filed: 1990-08-29
Granted: 1994-09-13
Abstract: An apparatus for severing the fillets from fish rumps comprises cutting tools each composed of pairs of circular knives for cutting free the belly spokes, the back spokes and the ribs or vertebral appendages, respectively.  The last mentioned cut-ting tool has a double function which consists in that each circular knife of this tool is associated with a guiding element, which, in its rest position, lies against the inner face of the circular knife with its guiding face.  The guiding edges of the guiding elements support the vertebrae of the verte-bral column and can be displaced within the cutting planes of the circular knives and can be controlled, in their displaced position, into a position in which a gap for the passage of the ribs or the ver-tebral appendages is opened between the inner face of the circular knives and the guiding face.  The displacement of the guiding elements occurs by the effect of transporting disks, which support the ver-tebrae of the vertebral column on the opposing side.

Title: Method and apparatus for describing data to be exchanged between processes
Inventor: DEMERS RICHARD A
IPC: G06F12/00
Filed: 1991-01-24
Granted: 1995-03-14
Abstract: The invention establishes the context in which data exchanged between dissimilar relational database management systems  can  be  mutually  understood  and  preserved.   The invention  accomplishes  this  by  establishing  layers  of descriptive     information    which     isolate     machine characteristics, levels of support software, and user data descriptions.    Optimized   processing   is   achieved   by processing  the  different  descriptor  levels  at  different times during the development and execution of the database management  systems.   Minimal  descriptive  information  is exchanged  between  the  cooperating  database  management systems.   For  systems  which  match,  data  conversion  is completely avoided.  For systems which do not match, data conversion is minimized.

Title: Method for locating sub-terranean geological aggregate deposits
Inventor: ROWE DOUGLAS J
IPC: G01V5/02
Filed: 1992-06-01
Granted: 2001-02-20
Abstract: This invention relates to the field of prospecting to locate mineral deposits particularly gravel and clay deposits. The method of prospecting to locate these mineral deposits includes the steps of traversing an area of the earth's surface and obtaining measurements of gamma radiation corresponding to the presence of uranium, potassium and thorium at spaced points along the traverse .      The data collected are used to determine an area mean value for the gamma radiation measurements obtained. The mineral location is obtained by noting areas within the area traversed in which the variations of the measurements of gamma radiation corresponding to each of uranium, potassium and thorium relating to the respective area mean values are indicative of the particular mineral being located. It has been found that aggregates may be located by looking for areas in which the gamma radiation corresponding to uranium is approximately equal to the area mean value while the measurements corresponding to potassium are low relative to the area mean and the measurements corresponding to thorium are low relative to the are mean. Clay may be located by noting areas in which the measurements corresponding to uranium are relatively high compared to the area mean value, the measurements corresponding to potassium are high relative to the area mean and the measurements of thorium are high relative to the area mean respectively.

Granted: 1998-06-30
Abstract: The method of this invention relates to preparing a bone to secure a prosthesis thereto by improving the mechanical interdigitation of bone cement and the bone and faciliting hemostasis of the bone. First, the bone is mechanically shaped to expose cancellous bone in a desired configuration for reception of a joint prosthesis. A pressurized jet of dry-flowing gas is then applied to the exposed bone, to clean and dry the trabecular interstices of the exposed cancellous bone. To further withdraw debris and liquids dislodged from the interstices of the prepared bone by the pressurized jet of dry-flowing gas, suction is applied to the bone concurrently with the application of the pressurized jet of dry-flowing gas. Bone cement in liquid form is then applied to the bone, with cement penetration into the cleaned and dried interstices of the bone.

Granted: 1997-03-04
Abstract: A process is presented for minimizing oxidative degradation of whole wheat flour in the production of whole wheat pasta.  A sweet nutty flavor is preserved and off-flavors are avoided by whole milling without removing the germ, not fine grinding the wheat, and immediately mixing the freshly-ground whole wheat flour with water to produce a dough or alimentary paste.  This minimizes the exposure of oils and other components to enzymatic and other degradative processes.
