Title: Method and apparatus for audio editing of midi files
Inventor: LISLE RONALD J
IPC: G10H1/00
Filed: 1991-10-04
Granted: 1994-03-15
Abstract: ABSTRACT OF THE DISCLOSURE     METHOD AND APPARATUS FOR AUDIO EDITING OF MIDI FILES          A method and apparatus are disclosed for the audio editing  of  MIDI  (Musical  Instrument  Digital  Interface) files.  MIDI files make it possible to exchange information such as: musical notes, program changes, expression control and  channel  information  between  musical  instruments, sequencers,  computers,  lighting  controllers  and  mixers. MIDI files generally consist of serially listed channel and system  messages  which  include  at  least  program  status messages and matching note on and note off messages.  The method  and  apparatus  of  the  present  invention  may  be utilized to ensure the integrity of a source file, a copied or  lifted  section  or  a  target  file  by  automatically inserting matching note on or note off messages into a file or file section to correct inconsistencies created by such editing. Additionally, program status messages are automatically inserted into source files, copied or lifted sections, or target files to yield results which are consistent with the results which may be obtained by editing digital audio data. Timing information is selectively added or maintained such that MIDI files may be selectively edited without requiring a user to learn a complex MIDI sequencer.

Title: Intaglio printing machine
Inventor: BLASS ERNST ANTON
IPC: B41F9/08
Filed: 1992-07-06
Granted: 2004-09-14
Abstract: The invention relates to an intaglio printing machine having a plate cylinder, and an impression cylinder which is equipped with an actuator for engagement and disengagement and can be adjusted by means of this actuator between an operating position resting on the plate cylinder and a position of rest removed from the latter. A wiping device has a wiping cylinder which interacts with the plate cylinder, and likewise can be adjusted by means of an actuator between an operating position, in which it rests on the plate cylinder with predetermined pressure, and a position of rest removed from the plate cylinder. The wiping cylinder is mounted in eccentric bushes and can be coarsely adjusted by means of hydraulic cylinders, by which the eccentric. bushes can be rotated, between its operating position resting on the plate cylinder and a position of rest removed from the latter. Additionally, a fine adjustment is provided, by which the change in spacing between the axles of the plate cylinder and the wiping cylinder, as a result of deflection of the plate cylinder occurring during the engagement of the impression cylinder, can be compensated. For this purpose, the hydraulic cylinders are each attached to a worm wheel which can be rotated by a worm spindle. Providing the fine adjustment of the worm spindle is a stepping motor, which is adjusted simultaneously with the engagement and disengagement of the impression cylinder in each case by a preselectable amount in either direction.

Title: Adjustable-speed alternating current motor
Inventor: VASILE POP F
IPC: H02K16/02
Filed: 1992-07-03
Granted: 1997-01-28
Abstract: In an induction motor, which  may be squirrel-cage or wound-rotor, it  is known  that the  speed of the  motor depends  o the power supply  frequency and the number of stator poles.  Although the speed of  a wound-rotor  type can be  controlled by  external resistors, the speed depends mainly on the load.    In this invention  the speed  of an induction  motor can  be fully controlled -  independent of the load - by  applying a very small  amount of  direct current  on the  motor's field  windings which interact with an intermediate rotor, without any alteration or change in the power supply.

Title: Transmission parking brake
Inventor: JOLLIFF NORMAN E
IPC: F16H63/48
Filed: 1993-01-07

Title: Preparation and polymerization of perfluoroalkoxy alkylene oxides to prepare hydrophobic polyethers
Inventor: MALIK ASLAM

Abstract: Oxetane monomers having perfluorinated alkoxy side chains; a method for their preparation; a method for their polymerization; and the resultant prepolymers are disclosed. The monomers have the formula:   wherein n is 1 to 5, m is 1, R is hydrogen or alkyl having from 1 to 4 carbons; and R f is linear or branched chain perfluorinated alkyl having from 1 to 20 carbons, or an oxaperfluorinated polyether, having from 4 to about 60 carbons, and the resultant prepolymers have the formula:   wherein n is 1 to 5, m is 1, R is hydrogen or alkyl having from 1 to 4 carbons, R1 is alkylene or isoalkylene having 2 to about 5 carbons, R f is linear or branched chain perfluorinated alkyl having from 1 to 20 carbons, or an oxa-perfluorinated polyether, having from 4 to about 60 carbons; and x is 2 to about 250. The monomers are prepared by the reaction of fluorinated alkoxides with aryl sulfonate derivatives of 3--hydroxyalkyl oxetanes, e.g., the p-toluene sulfonate derivative of 3-hydroxymethyl-3-methyl oxetane or of 3,3-bis(hydroxymethyl)oxetane. A high yield of the oxetanes having pendant perfluorinated alkoxy side chains is obtained. The fluorinated alkoxy oxetane monomers of this invention can be readily polymerized in the presence of Lewis acid catalysts and polyhydroxy aliphatics to obtain high yields of hydroxyterminated prepolymers having molecular weights from 1,000 to about 30,000, and a polymer backbone resulting from the opening of the oxetane ring.

Title: Dynamic axial splint
Inventor: FACCIOLI GIOVANNI
IPC: A61B17/60
Filed: 1993-07-27
Granted: 1996-08-13
Abstract: A dynamic external axial splint for use in rehabilitating a fractured bone comprises a pair of spaced clamps for bone screws or bolts anchored to the respective fragments of the fractured bone. A central body releasably and universally connects and locks these spaced clamps via ball-joints having provision for selective retention of a wide variety of angular relations, between the central body and the central axis of each of the spaced clamps. The central body comprises first and second end members and a third or intermediate member, affording on the one hand, longitudinally and adjustably fixed lap of one end member with the intermediate member, and also affording limited resiliently snubbed and axially guided displaceability as between the intermediate member and the other end member, thus rendering the two end members and the respective bone-fragment anchorages clamped to the end members subject to the same axially guided and resiliently snubbed action. The axially displaceable and resilient snubbed action is selectively neutralized by a single clamp adjustment which converts the dynamic external splint into a fixed external splint or fixator.

Abstract: A viscous damper for influencing and retarding rotation of a shaft, particularly the reel shaft of a roll-down fire door. The viscous damper unit comprises a housing having radially extending lugs, a cover for mounting to a side face of the housing, and a rotor arranged to be trapped between the cover and the housing and rotatable with respect to the housing.      The rotor provides a bore for receiving the roll-down shaft for the fire door. The housing lugs are positioned to be selectively locked with respect to the framework of the fire door to prevent rotation during down rolling of the fire door. A viscous material is applied between the housing, the cover, and the rotor which retards the rotation of the rotor with respect to the housing by sheer forces. The housing is arranged to be compatible with a plurality of damping units being axially stacked along the shaft and provides aligned apertures for pinning or bolting the plurality of the housings together. In this way, the damping influence of the assembly can be adjusted by adding or subtracting units.
