Title: Potato flavor enhancing composition and method
Inventor: WILLARD MILES J
IPC: A23L19/18
Filed: 1987-06-16
Granted: 1993-12-14
Abstract: ABSTRACT     A non-volatile potato flavor enhancing composition is added  to  processed potatoes  to provide  a natural potato flavor.  The flavor enhancer comprises a sugar component, an acidic component provided by at least one acid naturally present in the potato, a metallic flavor component provided by at least one salt of a metal naturally present in a potato, and  a bitter  flavor component provided by potato solids heated in air at a sufficiently high temperature and for a sufficient length of time to cause browning of the potatoes to the extent that a bitter flavor potato component is pro-duced.   The preferred sugar is sucrose: the preferred acid component is a combination of citric and malic acids; and the  preferred  metallic  component  is  potassium  chloride, although a phosphorus salt also can be used.  Salt such as sodium chloride is an optional flavor constituent in the flavor enhancer.  The amount of sugar in the flavor enhancer can vary depending upon the amount of sugars naturally present in the potatoes to which the flavor enhancer is added.  The flavor enhancer is used for improving the flavor of processed potatoes  such  as  dehydrated  mashed  potatoes,  fabricated potato snacks, hash brown potato patties, and the like.  The flavor enhancer can be added to the water of hydration used for reconstituting dehydrated potato pieces.   The flavor enhancer produces a complete fresh potato flavor profile in the finished product without any of the flavor constituents being evaporated or altered during subsequent processing, such as heating at elevated temperatures, frying, reconsti-tution; or during subsequent storage.

Title: Computer system architecture implementing split instruction and operand cache line-pair-state management
Inventor: WOFFINDEN GARY A
IPC: G06F12/0846
Filed: 1987-10-16
Granted: 1991-10-15
Abstract: Abstract of the Invention A computer system architecture implementing multiple central processing units, each including a split instruc-tion and operand cache, and that provides for the manage-ment  of multiple copies  (line pairs)  of  a memory  line through the use of a line pair state is described.  System-atic  management  of  memory  lines  when  transferred  with respect to  instruction and  operand data  cache  memories allows the integrity of the system to be maintained at all times.  The split cache architecture management determines whether a memory line having a first predetermined system address is present within both the instruction and operand cache memories or will be upon move-in of a memory line. Address tag line pair state information is maintained to allow determinations of whether and where the respective memory line pair members reside.  The architecture imple-ments the management of the line pairs on each transfer of a memory line to any of the split caches of the system. A line pair is allowed to exist whenever the same memory line exists in the same relative location in each of the in-struction and operand cache buffers of a single central processor.  The architecture further includes a data path selector  for  transferring  operand  data  to  either  the instruction or operand data cache buffers, or both, depend-ing on whether the operand buffer destination is a memory line that is a member of a line pair.

Patent CA-1286730-C (CA)
Inventor: MOHR GLEN R
IPC: B29C65/02
Filed: 1987-12-30
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE          This relates to an induction heating coil which is of a single turn construction and particularly configurated for inducing electrical energy into a metal foil barrier layer of a laminated container closure for effecting heat bonding of the closure to a container in a preselected seal pattern.  The seal pattern contains either one corner or the closure is provided with a projecting pull tab wherein there is a greater heating requirement and thus a requirement for the induction of higher electrical energy into the closure.  The need for the induction of a greater amount of heat  into the closure at a corner or the location of a projecting pull tab is provided for by reducing the cross section of the heating coil at the location of the greater heat requirement.  The reduction in cross section is primarily effected by forming a notch in the heating coil.  If desired, a closer control of the heating effect of the coil may be obtained by positioning in the notch a ferrite insert.

Title: Heat seal temperature control
Inventor: WEYANDT RONALD R
IPC: B29C65/18
Filed: 1988-03-16
Granted: 1993-06-08
Abstract: Heat Seal Temperature Control Abstract Method and circuitry is disclosed for controlling and stabilizing temperature of a resistance heat sealing element used in packaging operations.  Temperature of the heat sealing element is measured by monitoring its resistance by means of a current sensing resistor placed in series with the heat sealing element.  The resistivity of the heat sealing element is a function of temperature and current measurement, assuming substantially constant applied voltage, is an accurate measure of sealing element temperature.  The circuitry reduces application of electric power to the sealing element in response to current in the sealing element dropping below a predetermined level.          The circuit either continues application of electric power, or increases it, in response to the current being above the predetermined level.  Circuitry is also provided for compensating for undesirable line voltage changes to maintain the heating element at a constant temperature.          Means is provided for adjusting the predetermined temp-erature at which power cut off occurs.  The circuit and sealing element can be operated in either a continuous manner of in a "one-shot" fashion which has been deter-mined as particularly useful for making seals which bear embossed indicia.

Title: Mechanical penile prosthesis
Inventor: LEVIUS DEZSO K
IPC: A61F2/26
Filed: 1988-07-20
Granted: 1991-12-24
Abstract: P.C. 7186 MECHANICAL PENILE PROSTHESIS                       ABSTRACT A mechanical penile prosthesis includes a sleeve that encapsulates a linear assembly of cups, an actuating means and a cable.  The linear assembly of cups allows the prosthesis to be bent from an erect position to a flaccid position.  The actuating mechanism includes a biasing member, a poppet with first and second shoulders, one or more sliding rings, and a flexible tine.  Bending the prosthesis from its erect position to its flaccid position causes the poppet to move toward the distal end of the prosthesis, allowing the tines to lock behind the second shoulder.  To return the prosthesis to its erect state the prosthesis is bent further until the sliding ring separates the tines, allowing the biasing member to force the second shoulder past the tines; the tines snapping back into a position on the proximal side of the first shoulder.  A second poppet positioned at the distal end of the prosthesis or a second sliding ring that envelopes the first sliding ring may be included to allow the prosthesis to be bent into a super flaccid position, allowing easier surgical implantation of the prosthesis.
