Patent FI-86866-C (FI)
Inventor: GAROFF THOMAS
IPC: C08F4/60
Filed: 1990-12-19
Granted: 1992-10-26
Abstract: When asymmetric olefins or a monomer mixture containing asymmetric monomers is polymerized by a catalyst composition containing esters of carboxylic acid e.g. as a so-called donor, and alcohol the ester group can be transesterificated with the alcohol to an ester containing another alkyl group during the preparation and/or polymerization of the catalyst. This is advantageous particularly when an adduct of a so-called spray-crystallized Mg-halide and alcohol is used as the catalyst carrier, because the alcoxy group of the alcohol of the carrier and the alcoxy group of the ester of the donor can be transesterificated and thus obtain the preferable effects of both esters on the run of the polymerization reaction. Hereby, a solvent having a high boiling point should be used as the intermediate agent, so that the transesterification reaction can take place. Most preferable have been found hydrocarbons having high boiling points, especially nonane and decane.

Title: Diesel engine timing apparatus and method
Inventor: THEOFANOUS THEOS E
IPC: F02P17/12
Filed: 1989-11-14
Granted: 1995-10-31
Abstract: A diesel engine timing apparatus comprising a luminosity probe including a photocell which in response to light generated by combustion of fuel in a selected chamber of the diesel engine generates an on or off signal depending on the respective presence or absence of light.  Electronic circuitry elements process the on or off signal to produce an amplified output signal which is transmitted to light-generating elements disposed externally of the engine, e.g. a conventional inductive pick-up strobe-type tlmlng light.  A pulsed visible light signal is thereby generated which may be employed to adjust the engine timing to a selected value in a conventional manner, by aligning of fixed and adjustable timing marks on stationary and motive portions of the diesel engine.  The disclosed system is devoid of any magnetic probe or magnetic sensing structure.

Title: Spread spectrum signal demodulator
Inventor: VAN DRIEST HANS
IPC: H04B1/707
Filed: 1990-01-29
Granted: 2000-06-13
Abstract: In a digital data receiver (80) for demodulating a direct sequence spread spectrum differential phase shift keyed data signal, the signal is applied to the input transducer (140) of a SAW device (100) which has first and second output transducers (142, 144) spaced apart on the SAW substrate (130) so as to produce first and second output signals on output lines (102, 104), which are relatively delayed by a time corresponding to a symbol period. The output transducers are of identical construction and are matched to the spread spectrum code utilized in the data signal. Thus, a single SAW device (100) effects both correlation and delay. The output signals on the output lines (102, 104) are processed by a circuit including multipliers (106, 110) and a phase shifter (108) to produce output data signals representing the received data.

Title: Circuit implementation of block matching algorithm with fractional precision
Inventor: YANG KUN-MIN
IPC: G06T7/20
Filed: 1990-04-18
Granted: 1994-11-01
Abstract: A circuit for carrying out a full search block matching algorithm with fractional pixel precision comprises a first subcircuit for obtaining displacement vectors with integer pixel value precision and a second subcircuit for correcting the displacement vectors obtained by the first subcircuit so that the displacement vectors have fractional pixel value precision.  To obtain a displacement vector with integer pixel value precision for a block of pixels of a current video frame in a search area of a previous video frame, the first subcircuit finds a first specific position of the block with the smallest error out of a first plurality of positions defined by integer pixel values in the search area. The second subcircuit interpolates the integer pixel values of the first specific position to obtain fractional pixel values which define a second plurality of positions in the search area. The second subcircuit then determines which position of the block in the second plurality of positions has the smallest error, thereby providing a correction with fractional pixel precision for the displacement vector.
