Publication number: 20120056376Abstract: The jigsaw puzzle has a number of cubic playing pieces. On each of the six facets of each playing piece is displayed a segment of one of six different pictures. When the facets of one such picture all face upward and the cubes are correctly arranged side by side each other, the upwardly facing segments of the picture combine to display the complete picture. Similarly, when the cubes are arranged in turn so that the segments of the other five pictures are facing upwardly, the segments combined to display in turn the five other pictures. A magnetized sheet is provided on which the cubes are placed. The cubes are attracted to the sheet and remain stationary once they are placed on it so that it is unnecessary for the cubes to interlock to remain stationary when the puzzle is being worked on.Type: ApplicationFiled: September 2, 2011Publication date: March 8, 2012Inventor: Roger Morrison

Patent number: 7402993Abstract: Methods of detecting atypical patterns of usage of electricity, determined by monitoring consumption at the primary line, permit detection of grow-ops and unusual line losses due to defective service lines. A meter having a high resolution is connected to the primary line and the data collected is compared to known consumption patterns thus identifying a potential theft or a loss. Once an atypical pattern has been found, the heat signatures of transformers fed by the primary line are measured. An unusual heat signature alerts the utility to load test the secondary lines of each residence fed from the transformer and thus locate suspect residences which may be grow-ops or to locate a line loss due to defective service lines.Type: GrantFiled: May 31, 2006Date of Patent: July 22, 2008Assignee: Dtechs EPM Ltd.Inventor: Roger Morrison

Patent number: 5993643Abstract: There is provided a hydrocracking process using a catalyst comprising a hydrogenation/dehydrogenation component, such as a noble metal, and an acidic solid component comprising a Group IVB metal oxide modified with an oxyanion of a Group VIB metal.

Patent number: 5865986Abstract: This is a process for upgrading a petroleum naphtha fraction. The naphtha is subjected to reforming and the reformate is cascaded to a benzene and toluene synthesis zone over a benzene and toluene synthesis catalyst comprising a molecular sieve of low acid activity. The preferred molecular sieve is steamed ZSM-5. The benzene and toluene synthesis zone is operated under conditions compatible with the conditions of the reformer such as pressures of above about 50 psig (446 kPa) and temperatures above about 800.degree. F. (427.degree. C). In one aspect of the invention, the benzene and toluene synthesis catalyst includes a metal hydrogenation component such as cobalt, nickel, platinum or palladium. In one mode of operation, the benzene and toluene synthesis catalyst replaces at least a portion of the catalyst of the reformer. The process produces a product containing an increased proportion of benzene and toluene, and a reduced proportion of C8 aromatics, particularly ethylbenzenes, as compared to the reformate.Type: GrantFiled: November 3, 1995Date of Patent: February 2, 1999Assignee: Mobil Oil CorporationInventors: John Scott Buchanan, Jane C. Cheng, David G. Freyman, Werner Otto Haag, Mohsen N. Harandi, Dominick N. Mazzone, Roger A. Morrison, Norman J. Rouleau, Charles M. Sorensen, Hye Kyung C. Timken, Robert Adams Ware

Patent number: 5409595Abstract: Catalytically cracked naphthas containing C.sub.9 + hydrocarbons are hydrocracked over a crystalline zeolite, typically, mildly steamed zeolite beta then subjected to reforming to achieve a gasoline product of reduced end boiling range and higher octane than the feed. A hydrogen stream from the reformer which contains a catalytic promoter, such as chlorine, is separated into a first stream and a second stream. The first stream is treated over a solid sorbent to remove the promoter and recycled promoter to the hydrocracking step while the untreated second hydrogen stream which contains promoter is recycled to the reformer.Type: GrantFiled: April 4, 1994Date of Patent: April 25, 1995Assignee: Mobil Oil CorporationInventors: Mohsen N. Harandi, Roger A. Morrison, Gerald J. Teitman

Patent number: 5397457Abstract: A hydrocarbon fraction, preferably in the kerosene boiling range containing a substantial proportion of C.sub.9 + hydrocarbons is contacted with an n-paraffin fraction, such as n-pentane, over a catalyst of acidic functionality, such as Pd/zeolite beta, under conditions of hydrocracking sufficient to convert the feed to lower boiling range materials of high octane number. The n-paraffin cofeed promotes isomerization and suppresses production of n-paraffins.Type: GrantFiled: February 25, 1994Date of Patent: March 14, 1995Assignee: Mobil Oil CorporationInventors: Mohsen N. Harandi, Roger A. Morrison

Patent number: 5396010Abstract: A fluid catalytically cracked heavy naphtha containing a substantial proportion of preferably more than 90% C.sub.9 + hydrocarbons is contacted with a reformate heavy naphtha containing a substantial proportion of C.sub.9 + hydrocarbons and, optionally, a benzene-rich stream, over a catalyst of acidic functionality, preferably unsteamed ZSM-5, under transalkylation reaction conditions of temperature and pressure to produce a gasoline boiling range product, boiling below 300.degree. F., having a reduced sulfur content and an increased octane number. In one mode of operation the reformate is cascaded from the reformer as the conditions of reaction are compatible with the conditions established in the reformer.Type: GrantFiled: August 16, 1993Date of Patent: March 7, 1995Assignee: Mobil Oil CorporationInventors: Mohsen N. Harandi, Roger A. Morrison
