Abstract: ASSEMBLY FOR COUPLING SWITCH HANDLES     Abstract of the Disclosure A switch coupling assembly for coupling at least a pair of switched having respective spaced apart actuator handles is provided in order to permit simultaneous switching of the separate switches.          Generally tubular spacers fit between each pair of switch handles.  At least one tubular spacer is dimensioned with sufficient clearance so that one end of the spacer abuts one of the switch handles while the other end of the spacer is spaced apart from the other switch handle.  The switch handles are each provided with alignable openings and a tie rod is dimensioned to extend through the aligned openings in the switch handles and the spacers to couple the switch handles together.  The tie rod has a groove alignable in the clearance between the spacer and the adjacent switch handle.  A snap ring snugly fits in the clearance to hold the spacer in position and engages the groove on the tie rod to prevent relative movement of the tie rod.  The switch handles are thereby coupled together to enable simultaneous movement of the handles.

Title: Process for the production of block copolymer of propylene
Inventor: ASANUMA TADASHI
IPC: B23Q39/02
Filed: 1986-12-10
Granted: 1990-11-13
Abstract: Abstract of the Disclosure A block copolymer of propylene is produced by using propylene itself as a liquid medium, conducting continuous polymerization (former-stage polymerization) of propylene alone or propylene and a small amount of ethylene at first and then conducting batchwise copolymerization (latter-stage polymerization) of ethylene and propylene.  The amount of an activity improver to be added to a polymerization tank for the latter-stage polymerization and/or the polymerization time of the latter-stage polymerization are controlled in accordance with the amount of a slurry transferred from a polymerization tank for the former-stage polymerization to the polymerization tank for the latter-stage polymerization so as to maintain the ratio of the amount of the polymer polymerized by the former-stage polymerization to the amount of the polymer polymerized by the latter-stage polymerization constant in the block copolymer.     By practicing the process of this invention, a propylene copolymer of reduced quality variations and excellent stiffness and impact resistance can be obtained.

Title: Microwavable shaped rice and grain product
Inventor: ZUKERMAN HAROLD W
IPC: A23L7/196
Filed: 1987-03-27
Granted: 1992-05-12
Abstract: Abstract A  microwavable  shaped  rice  product  made  with limited amounts of water, producing cooked rice grains with centers that are not fully hydrated.   These shaped rice products are held in frozen storage and prior to serving they are reheated in a microwave oven.  When the shaped rice products are microwave reheated from the frozen state, a portion of their water that was originally bound with the rice grain structure is released.   During this microwave reheating,  this  released water becomes very hot,  both cooking and being absorbed by the not fully hydrated rice grain centers.  When microwavable shaped rice products are later served, they have a crust and their overall inner texture is soft and firm, but not soggy.

Abstract: ACID CATALYSTS AND METHODS OF USE ABSTRACT Compositions containing sulfuric acid and one or more of certain chalcogen-containing compounds in which the chalcogen compound/H2SO4 molar ratio is below 2 contain the mono-adduct of sulfuric acid which is catalytically active for promoting organic chemical reactions. Suitable chalcogen-containing compounds have the empirical formula: wherein X is a chalcogen, each of R1 and R2 is independently selected from hydrogen, NR3R4, and NR5, at least one of Rl and R2 is other than hydrogen, each of R3 and R4 is hydrogen or a monovalent organic radical, and R5 is a divalent organic radical. Such compositions are useful for catalyzing organic reactions such as oxidation, oxidative addition, reduction, reductive addition, esterification, transesterification, hydrogenation, isomerization (including racemization of optical isomers), alkylation, polymerization, demetallization of organometallics, nitration, Friedel-Crafts reactions, and hydrolysis. Novel catalysts are disclosed which involve combinations of the chalcogen compound-sulfuric compositions with one or more transition metal halides and/or with one or more surfactants. The surfactant-containing compositions are particularly useful for the treatment of materials containing lipophilic substances.

Abstract: ABSTRACT       Specific radial-type or branched rubbers are used to prepare rubber-reinforced monovinylidene aromatic polymer resins.  It has been found that such rubbers wherein the solution viscosity is less than 60 cps, the Mooney viscosity is relatively low and the ratio of Mooney viscosity to solution viscosity falls within certain ranges can be used to prepare improved ABS- and  HIPS-type resins.  The rubbers should have Mooney and solution viscosities such that the ratio of the Mooney to solution viscosities is at least 0.7 for the ABS-type resins and at least 1.1 for the HIPS-type resins.  The use of these rubbers also provides improved mass-type polymerization processes wherein higher rubber concentrations can be acheived at the same time that improved products are obtained. 35,795-F
