Abstract: There is disclosed a temperature controller for controlling a coolant temperature in a liquid cooling system comprising a liquid circulation circuit in which coolant for cooling a machine circulates and a refrigeration circuit for cooling the coolant. 
     More specifically, when the operating capacity of a compressor of the refrigeration circuit is variably adjusted by an inverter and when the operating condition of the machine is changed, its frequency value is varied in accordance with the change, so that it is possible to immediately correspond to the change of a liquid temperature to be generated in the future. In addition, an appropriate control can be selected as a control varying the frequency in combination with a normal feedback control, wherein the liquid temperature may converge on a set value or it may be co-changed to a room temperature or the like.

Abstract: A method and apparatus for performing a bit map search of the allocation state of memory pages in a computing system. A competitive search is accomplished by a pair of dedicated microprocessors, each of which implements a differently optimized search procedure, to find a bit indicating an un-allocated page in the memory. The first processor to find such a bit interrupts the other processor. The first processor then calculates the free page location and informs the computing system of the location. The other processor is responsible for updating the bit map and summary buffers.

Abstract: Disclosed is a method of treating a free-radical-containing, optionally room-temperature-aged, irradiated, normally solid high-molecular-weight, semi-crystalline propylene polymer material at about from 40°C to 110°C for at least about 10 minutes before being exposed to the higher temperatures that deactivate the residual free radicals therein. Treatment of the polymer at the intermediate temperature causes recombination, and better utilization, of free radicals with the production of more long-chain branching. A two-stage fluid bed process, with a first stage at the intermediate temperature for radical recombination and a second radical-deactivation stage at a higher temperature, is preferred.

Abstract: Described is a process for producing, in particu­late form, aromatic polyimides based on one or more 2,2-­bis[4-(aminophenoxy)phenyl]hexafluoropropanes. The process involves forming, heating and agitating in a medium composed of dipolar aprotic solvent and liquid aromatic hydrocarbon solvent, a homogeneous solution of a polyamic acid derived from a substantially equimolar mix­ture of (i) an aromatic tetracarboxylic dianhydride and (ii) a 2,2-bis[4-(aminophenoxy)phenyl]hexafluoropropane, such that a separate phase of particulate aromatic poly­imide is formed in such medium. The process avoids difficulties caused by the tendency of the wet polyimide polymer to agglomerate into stringy or tacky masses which can foul reactor and agitator surfaces.

Abstract: A system and method are shown for performing cool, on-column sample injection into a chromatographic device having a capillary column (14) which injection is achieved through the use of a syringe having a needle (116). The column diameter is minimized by the provision of an inlet assembly connected to the inlet end of the column, a sealing member (104) disposed in the inlet assembly, for forming a fluid tight seal in the inlet end when the sample is injected onto the column to prevent the sample from escaping and for reducing the effective length of the needle at the point of insertion of the needle into the column and a guide member (90) for reducing the effective length and for supporting the needle during insertion into the column. A temperature controller for controlling the temperature of the column in the region where the sample is injected is also disclosed. The sealing member is shown to include an elastomeric member (104) and further the system includes a mechanism for continuously cooling the elastomeric member. The elastomeric member is shown to include a septum having a bore formed therein for passage of the needle therethrough. A new sample vial closure is also shown for use in the system, which closure applies only a minimal axial force on the needle. In such a system and method the need for a long syringe is obviated. The column inner diameter can be minimized by the system and method which permits the needle of the syringe to have a minimum outer circumference.
