Patent CA-2048799-A1 (CA)
Title: Propeller pitch control
Inventor: MILLER EDWIN K
IPC: B64C11/32
Filed: 1991-08-08
Abstract: ABSTRACT OF THE DISCLOSURE  The invention concerns a system for controlling an aircraft propeller.  A hydraulic motor controls pitch of the propeller blades.  The propeller blades are characterized by the absence of feather-inducing counterweights.  An overspeed governor senses when propeller speed exceeds a limit, and, in response, assumes control of the hydraulic motor and drives the blades toward a coarsened pitch position, which reduces the propeller speed.  In another form of the invention, a mechanical brake can override the hydraulic motor and mechanically retard a rotating gear, which causes the propeller blades to move toward a coarsened pitch.

Filed: 1991-08-23
Abstract: A process for preparing frozen coated potato products is disclosed.  Raw potatoes are washed, cut, blanched, and partially dehydrated.  The cut potatoes are then coated with an aqueous starch slurry.  The aqueous starch slurry is comprised of a combination of modified ungelatinized potato starch, modified ungelatinized corn starch, rice flour and other optional ingredients.  The coated potato strips are parfried in oil, then frozen.  The frozen strips are prepared for consumption by either finish frying in hot oil, or heating in an oven.  The starch coating enhances the holding quality of the ready to consume product.  It also improves the acceptability of the finished product by increasing the crispiness of the outer surface, and helping to maintain the tenderness of the interior of the cut potato.

Title: Apparatus and process for producing shaped articles from semisolid metal preforms
Inventor: BRUECKER GORDON W
IPC: B22D17/32
Filed: 1991-10-22
Abstract: ABSTRACT            Shaped metal articles are produced on a continuous basis from  semisolid  metal  preforms.   The  metal  preforms  are sequentially heated, then transferred, without substantial deformation or heat loss to a press where they are shaped in the semisolid state into shaped articles.   While in the press, a ram is employed to drive the preform into a cavity of adjacent tooling to thereby shape the article.  Prior to the forming operation, the ram is first advanced until it lightly engages the preform, then is withdrawn by a spaced distance to a first position defining the beginning of a stroke.  Then, the ram is advanced, rapidly, from the first position against the preform to a second position contiguous with the tooling, thereby defining the end of the stroke. The spaced distance is chosen so as to preclude substantial heat drain from the preform and/or forced entry of air into the cavity and/or splashing of the semisolid metal outside of the cavity.  Just before reaching the second position, the ram may be accelerated to preclude the formation of voids in the finished article.

Title: Video telephone employing pulse width modulation for data transmission
Inventor: PERELMAN FRANK M
IPC: H04N7/24
Filed: 1990-06-19
Abstract: A video telephone employing pulse width modulation (10) is implemented. Minimal components are employed and the entire circuit is comprised of digital components except for a few analog components including a comparator (98) for detecting transitions in a received pulse width modulation signal. The pulse width magnitude for each transmitted data is determined by the binary value of the data input (81). The video picture along with the synchronization signals from a video source (12) are digitized and stored in a memory (24). The video telephone (10) operates by sending and receiving via pulse width modulation both the video data and the synchronization signals. The inverse of the video is entered into a binary counter (82) in the modem (80) and the pulse width is the result of counting to a transition of a more significant bit of the counter to create a pulse width modulation transmission on the telephone lines. On receiving pulse width modulation video the binary counter (82) is loaded with all ones and counted up until a transition of a received state is detected. Then the binary counter (82) is read to recover the sent data. Provisions are included to adjust for received pulse widths longer or shorter than expected (84). The data from the video source or the received video can be displayed on a local monitor (32).

Title: Method of dissolving cholesterol-rich calculi with short chain halogenated organic solvents and cosolvents
Inventor: DEANTONIO PAUL
IPC: A61B17/22
Filed: 1990-08-23
Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a method for dissolving cholesterol-rich calculi, most preferably gallstones in vivo, comprising contacting the calculus with a fluid compound of the formula R-X, R having 2 to 4 carbon atoms with substituents consisting of hydrogen or halogen, X being halogen, and wherein if X is fluorine, at least one substituent is selected from the  group  consisting  of  hydrogen,  chlorine,  bromine,  or  iodine. Usually R-X is 2-bromo-2-chloro-1,1,1-trifluoroethane (also referred to as Halothane.)  Other compounds of particular interest are 2-chloro-1,2,-dibromo-1,1,2-trifluoroethane,     1-bromo-2-chloro-1,1,2-trifluoroethane,   2,3-dibromo-1,1,1-trifluoropropane,   2-iodo-1,1,1-trifluoroethane,   1,2-dichloro-1,1-difluoroethane,   1,1,2-trichloro-2,3,3-trifluorocyclobutane,    hexafluoro-1,1,3,4,-tetrachlorobutane, 1,1,1-trichlorotrifluoroethane, and 1,2-dibromo-tetrafluoroethane. Furthermore, Halothane and MtBE in combination effectively dissolve cholesterol-rich calculi.      Finally, dissolution can be enhanced by adding to the dissolution solvent up to about 50 percent by volume of a lower alcohol.  Usually the lower alcohol is ethanol in the amount of about 5 to 40, usually 10 to 30 and preferably about 10 percent by volume.  Most preferably in this  case,  R-X  is  Halothane  or  1,1,1-trichlorotrifluoroethane. Dissolution using previously known solvents such as MtBE is also enhanced  by  such  addition  of lower  alcohols.    In addition,  the practical use of MtBE for dissolution can be improved by the addition of the compounds described above as R-X, particularly Halothane, and usually at levels of about 5 to 50 volume percent Halothane.
