Abstract: ABSTRACT OF THE DISCLOSURE     Alkoxides of transition metals, selected from the group consisting of tetravalent Ti, tetravalent and pentavalent V, tetravalent Cr and tetravalent Zr, are reduced to corre-sponding alkoxides of lower valency by reacting such higher valency metal alkoxides, in liquid phase, with vapors of at least one metal selected from the group consisting of alkaline earth, group III and group IV metals, and manganese.     Very efficient polymerization catalysts for the polymeriza-tion of unsaturated compounds are thus obtained.

Granted: 1982-05-25
Abstract: ABSTRACT      An air cooling arrangement for a column of integrated circuit modules is provided in which a pair of air moving devices are included, one located at the top and one at the bottom of the column each pulling air through the column.  A heat sink having opposite side air outlets is attached to each of the modules and extends from the top side thereof.  A cover plate having openings therein indexed with each of the heat sinks allows air to pass through the openings into the heat sinks.  An air flow guide is located at each air outlet side of each heat sink and extends from the cover plate vertically into each heat sink to approximately the half way point to provide a vertical impinging air flow pattern which yields a high heat transfer coefficient.  Air distri-bution ducts are arranged on opposite sides of the heat sinks parallel to the column and connected to the opposite side of air outlets of the heat sinks via air passages thereby providing a dividing of the flow across each heat sink.

Abstract: ABSTRACT OF THE INVENTION         The invention has for its object to provide a control unit for the air choke in an oil burning installation which affords good fuel economy and is simple in construction, while being at the same time easy to mount and adjust. The control unit is composed of a piston cylinder (14) the pressure side of which is connected to the pressure side of the fuel pump (22) of the plant in such a manner that its piston (24) performs a working stroke when the pump starts and returns to the starting position when the pump stops. The piston rod (18) of the piston cylinder unit is coupled to a throttle which opens as a result of said working stroke and closes on the return movement. The piston cylinder unit is provided with a mobile end position abutment which consists of a secondary piston (29) which is slidably mounted in a secondary cylinder housing (30) which communicates with a sensing device (33) disposed in or adjacent the flue gas duct of the burning plant, which sensing device encloses an expansion liquid, the degree of expansion of which depending upon temperature determines the displacement position of the secondary piston and thus of the end position abutment, and also the reduction of the degree of opening of the throttle on increased flue gas temperature, and vice-versa.

Abstract: ABSTRACT OF THE DISCLOSURE          The specification of the present application discloses an apparatus and method for dividing the multiple parallel output of a multi-lane container packaging machine to allow bulk packaging of a number of containers independent of the number of containers in one parallel output.  This is accomplished by changing the parallel container output into a series output in which the container spacing and position relative to other containers is determined by the output rate of the multi-lane packaging machine and the speed of a second conveyor positioned at the discharge of the machine to change the parallel input of containers to a series format.  A segmenting means is associated with the indexing of the multi-lane packaging machine and divides the time between successive indexes into divisions representative of the number and spacing of containers on the second conveyor.          These divisions are then used to determine when a specified number of containers have been bulk packaged, at which time the series output of containers is interrupted in preparation for loading another bulk container.
