Abstract: PCT No. PCT/FI91/00406 Sec. 371 Date Aug. 20, 1992 Sec. 102(e) Date Aug. 20, 1992 PCT Filed Dec. 20, 1991 PCT Pub. No. WO92/12182 PCT Pub. Date Jul. 23, 1992.The invention concerns a multi-stage process for producing polyethylene having a bimodal and/or broad molecular weight distribution in the presence of an ethylene polymerizing catalyst system in a multistep reaction sequence, in which the first reaction step is a liquid phase polymerization step and the second reaction step is formed by one or more gas-phase polymerization steps. According to the process of the invention in the first reaction step ethylene is polymerized in a loop reactor (10) in an inert low-boiling hydrocarbon medium the residence time being at least 10 minutes, reaction mixture is discharged from the loop reactor (10) and at least a substantial part of the inert hydrocarbon mixture is separated and the polymer is transferred into one or more gas-phase reactors (30), where the polymerization is completed in the presence of ethylene and optionally hydrogen and a comonomer. As an inert hydrocarbon medium in the loop reactor (10) propane can be used and the polymerization can be carried out also so that the mixture of inert hydrocarbon, monomer, hydrogen and optional comonomer is under supercritical conditions.

Title: Heat conducting interface for electric module
Inventor: WENKE GERHARD
IPC: B64D13/00
Filed: 1990-03-05
Granted: 1993-08-17
Abstract: ABSTRACT OF THE DISCLOSURE          A  heat  conducting  interface  unit  for  use  in mounting  an  electronic  module  between  cooling  plates, includes  an  elongated  flexible,  U-shaped,  highly  heat conductive  metallic  heat  exchange  member  adapted  to receive a condensor end of the electronic module.   The heat exchange member is located within a housing which provides liquid coolant chambers on the outside walls of the heat exchange member. The coolant is supplied under pressure through inlets in the housing from corresponding ports in the cooling plates.  The pressure in the coolant chamber urges the flexible metallic heat exchange member into  increased  contact  pressure  with  the  condensor portion of the  electronic module,  reducing the thermal resistance across the contact interface,  increasing the rate of heat transfer to the cold plate, and clamping the module in position.  The heat exchange member covers the entire  surface  of  the  condensor  to  maximize  heat transfer.  It also provides  a  simple  structure and  a short thermal path to the coolant.

Title: Transport refrigeration system having means for enhancing the capacity of a heating cycle
Inventor: RENKEN DAVID JON
IPC: F25B47/02
Filed: 1990-03-08
Granted: 1999-11-30
Abstract: A transport refrigeration system which includes a compressor, a condenser, a receiver, an evaporator, an accumulator, and a control valve which selectively initiates heating and cooling cycles. The heating capacity of a heating cycle is enhanced by connecting the outlet of the receiver to the inlet of the accumulator just prior to each heating cycle, while maintaining the control valve in a cooling position for a predetermined time delay. This forces any liquid refrigerant trapped in the condenser to flow into the receiver, while lower pressure in the accumulator causes liquid refrigerant in the receiver to flow into the accumulator, to provide additional liquid refrigerant in the accumulator at the start of the heating cycle, which is initiated at the end of the predetermined time delay.

Title: A method for the modification of catalysts intended for the polymerization of olefins
Inventor: GAROFF THOMAS
IPC: C08F4/654
Filed: 1991-11-28
Granted: 2000-10-31
Abstract: When asymmetric olefins or a monomer mixture containing asymmetric monomers is polymerized by a catalyst composition containing esters of carboxylic acid e.g. as a so-called donor, and alcohol the ester group can be transesterified with the alcohol to an ester containing another alkyl group during the preparation and/or polymerization of the catalyst. This is advantageous particularly when an adduct of a so-called spray-crystallized Mg-halide and alcohol is used as the catalyst carrier, because the alkoxy group of the alcohol of the carrier and the alcoxy group of the ester of the donor can be transesterified and thus obtain the preferable effects of both esters on the run of the polymerization reaction. Hereby, a solvent having a high boiling point should be used as the intermediate agent, so that the transesterification reaction can take place. Most preferable have been found hydrocarbons having high boiling points, especially nonane and decane.

A control circuit is coupled to the balance output for providing feedback signals as functions of the balance output for periodically charging and discharging the storage capacitance, whereby a first sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference within a first set of limits when a first capacitive magnitude is selected in the storage circuit, and whereby a second sequence of charge packets is provided on the charge output for driving the accumulation of charge toward the reference charge within a second set of limits when a second capacitive magnitude is selected in the storage circuit. A calculation circuit is coupled to the feedback circuit for counting the number of charged packets generated in a measurement cycle.
