Title: Vocal cord medialization prosthesis
Inventor: NETTERVILLE JAMES L
IPC: A61B17/24
Filed: 1992-09-18
Abstract: ABSTRACT OF THE DISCLOSURE A vocal cord medialization prosthesis includes a preformed and presized vocal cord engagement member.  The engagement member has a base surface and an engagement surface that is inclined a predetermined amount with respect to the base surface.  Measurement indicia is provided on the engagement member to indicate elevation of the engagement surface at predetermined points along the prosthesis.  A vocal cord medialization tool is used to measure displacement of a vocal cord to an optimum phonation and breathing position before insertion of the prosthesis.  The medialization tool provides measurements that correspond to sizing indicia on the prosthesis.  The prosthesis can thus be trimmed to eliminate elevations that are unnecessary for obtaining optimum positioning of a vocal cord.  One embodiment of the medialization tool also includes provision for measuring the thickness of a thyroid cartilage.

Title: Apparatus for compression encoding video signals
Inventor: YAMADA TAKAAKI
IPC: H04N19/65
Filed: 1992-12-24
Abstract: Apparatus for compression encoding video signals, comprising block segmenting means for segmenting a vertical interval, such as a field or frame, of video picture elements into a plurality of blocks of picture elements. An orthogonal transformation, such as discrete cosine transformation, of respective blocks is obtained, resulting in a two-dimensional array of transform coefficients of different values, the array being partitioned into respective areas. Each area is quantized with a respective quantizing value that differs for different areas. Preferably, a transform coefficient is quantized by dividing the value of the transform coefficients in an area by a divisor 2n/2, where n is an integer that differs in different areas. The areas of the two-dimensional array of transform coefficients are formed by partitioning the array in a direction substantially perpendicular to the oblique frequency axis of that array.   -i-

Title: Surface wave driven generator
Inventor: TREMBLAY PAUL J G
IPC: F03B13/18
Filed: 1993-07-06
Abstract: ABSTRACT      The development of surface water wave power, as a source of energy, has made little progress in the last fifty years, due mainly to the high cost of converting intermittent energy into a more sustainable form.  Two serious "prior art" projects, the British and the Japanese are examined in the "Disclosure".      A model of a SURFACE WAVE DRIVEN GENERATOR is proposed which uses economical small scale and presently developed technology.  Its distinguishable features from other inventions may be summarized as follows:      - the concept of this machine implicitly challenges the notion that large industrial hydroelectric type of installations offer the ideal model for a successful development of wave energy.  Instead, this is better achieved by smaller installations, which are capable of meeting the household needs of poor populations living off the coastlines of third world countries blessed with abundant, albeit unutilized wave energy.      - this invention makes full use of two devices [flywheel, compressed air] capable of storing energy in order to correct the intermittent nature of wave power.  In this respect, the most efficient energy storage device, the flywheel, plays the predominant role.      - the performance and efficiency of the compressed air process are increased through a scientifically controlled solar exposure of the walls of the compressed air container. - operational costs are substantially reduced if the sensitive and vulnerable parts of the wave driven machine are stationed ashore where they are easily accessible for repairs and surveillance.

Title: Riving knife drive mechanism for a portable circular saw
Inventor: SAUERWEIN WILLIAM D
IPC: B27G19/08
Filed: 1993-12-22
Abstract: RIVING KNIFE DRIVE MECHANISM FOR A PORTABLE CIRCULAR SAW            ABSTRACT OF THE DISCLOSURE A portable circular saw includes motor-and-gear case pivotally supported on a guide shoe by a rear pivot mechanism for rotation about a transverse rear pivot axis, thus allowing for selective adjustment of the blade cutting depth on the opposite side of the shoe. In such an arrangement, the depth of cut setting is increased and decreased when the motor-and-gear case is rotated relative to the shoe in respective first and second directions, while an upper pivotal blade guard, which is mounted on the motor-and-gear case for rotation about the spindle, rotates in opposite rotational directions in response to respective increases and decreases in the depth of cut setting. Cam and cam follower mechanisms are provided for maintaining the riving knife and the blade and shoe in the same relative angular orientation in a fore-and-aft cutting plane regardless of the depth of cut setting. Such riving knife actuation is accomplished by such mechanisms in response to the rotation of the rear-pivoted motor-and-gear case and the corresponding opposite rotation of the front-pivoted upper gear case.
