US Classification:

585449, 585467

Abstract:

A process is described for producing an alkylaromatic compound, in which a first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene are introduced into a first alkylation reaction zone comprising a first alkylation catalyst. The first alkylation reaction zone is operated under conditions effective to cause alkylation of the alkylatable aromatic compound by the alkene to produce said alkylaromatic compound, the conditions being such that the alkylatable aromatic compound is at least predominantly in the vapor phase. A first effluent comprising the alkylaromatic compound and unreacted alkylatable aromatic compound is withdrawn from the first alkylation reaction zone and at least part of the unreacted alkylatable aromatic compound is treated to remove catalyst poisons therefrom and produce a treated unreacted alkylatable aromatic stream. At least part of the unreacted alkylatable aromatic compound and a third feed comprising said alkene is introduced into a second alkylation reaction zone comprising a second alkylation catalyst. The second alkylation reaction zone is operated under conditions effective to cause alkylation of the unreacted alkylatable aromatic compound by the alkene to produce said alkylaromatic compound, the conditions being such that the alkylatable aromatic compound is at least predominantly in the liquid phase.

US Classification:

340323R

Abstract:

An electronically operated game scoring apparatus in the form of a relatively small hand-held portable housing. The housing is provided with a plurality of manually actuable input keys for introducing scoring information relative to a game. The housing includes an electrical circuit means and preferably a microprocessor for generating scoring information about the game or one or more players of the game. The housing is provided with a plurality of manually operable display controlling switches which provide for the display of scoring information regarding the game or the players and scoring information regarding a total score of the game or of an event in the game. In a preferred embodiment, a plurality of display members are included on the housing for substantially simultaneously displaying scoring information about different aspects of the game.

US Classification:

84312R

Abstract:

An adapter system for a stringed musical instrument having a tuning key and a string connected to the tuning key for adjusting the pitch of sound rendered by striking the string attached to said key. A limit stop is operatively mounted on the instrument along with a,rotational stop mounted on the key for interacting with the limit stop to confine the rotational movement of the tuning key to a certain predetermined arc. The limit stop can be adjusted to selectively change the angular arc. An internal adapter cylinder is operatively mounted on the shaft of the tuning key where the tuning key shaft is of a non-circular configuration. An upper cylinder and a lower cylinder are operatively mounted with respect to the internal adapter cylinder. The adapter cylinder is provided with a recess which accommodates a cylindrical insert used when the tuning key is not provided with a shoulder portion.
