Abstract: In a piece of equipment that attaches to a tractor for the purpose of doing farm related chores and material handling.      It is known to have one attachment for a single purpose and many attachments are needed to do the different chores in farming ie) material handling. In this invention only one attachment is needed and consists of a frame that is attached to the loader or three point hitch assemblies of the tractor, using common mounting methods and from this frame is attached a blade that pivots in the center of the frame and is moved from one side to the other by use of hydraulics. To the top of the blade is mounted a hook assembly which is used for grabbing and locking material. To the bottom of the blade is mounted a spear like assembly that can be used for many different functions in farm related material handling ie) manure, hay, wood, stumps, stones, etc. This spear like assembly can also be detached which will enable the unit to be used for plowing snow, grating, liquid manure, etc. Endcaps can also be added to the blade portion so as the blade can be used as a bucket. Other devices can also be added ie) hoist, boom, graffel or winch, etc.

Title: Data compression system
Inventor: SHAPIRO JEROME MARK
IPC: H03M7/30
Filed: 1992-10-01
Granted: 2002-08-13
Abstract: A data processing system augments compression of non-zero values of significant coefficients by coding (1410, 1412) en-tries of a significance map independently of coding the values of significant non-zero coefficients. A dedicated symbol represents a zerotret structure encompassing a related association of insignificant coefficients within the tree structure, thereby compactly representing each tree of insignificant coefficients. The zerotree symbol represents that neither a root coefficient of the zerotree structure nor any descendant of the root coefficient has a magnitude greater than a given reference level. The zerotree structure is disclosed in the content of a pyramid-type image subband processor (1408) together with successive refinement quantization and entropy coding (1418) to facilitate data compression.

Patent CA-2174660-C (CA)
Inventor: LO FREDERICK YIP-KWAI
IPC: C08F4/42
Filed: 1994-11-15
Granted: 2005-10-04
Abstract: An ethylene polymerization catalyst comprising two tran- sition metal components on a support with one of the two tran- sition metals in the form of a metallocene. An aluminum alkyl activator for the non-metallocene transition metal component is also present. The support is an anhydrous material prepared by reacting (i) a silanol-containing silica impregnated with a mag- nesium alkyl with (ii) an alcohol. The catalyst produces ethylene copolymer in a single reactor with a bimodal molecular weight distribution. The polymerization is practiced in a reactor (10) comprising a reaction zone (12), a velocity reduction zone (14) and a distributor plate (20). The reaction zone (12) comprises a bed of growing polymer particles and a minor amount of cata- lyst particles fluidized by the continuous flow of polymerizable and modifying gaseous components. The distribution plate dif- fuses the recycle gas. The recycle gas is separated in the cy- clone separator (22) from the catalyst particles, passes through the cooler (24), and is further compressed in compressor (25), passes through a heat exchanger (26), combines with a fresh feed and enters the reaction zone (12) through the distributor plate (20). When a desirable degree of polymerization has been ac- complished the polymer particles with bimodal molecular weight distribution are recovered from the reactor.
