Abstract: PCT No. PCT/US98/02634 Sec. 371 Date Mar. 9, 1999 Sec. 102(e) Date Mar. 9, 1999 PCT Filed Feb. 10, 1998 PCT Pub. No. WO98/34633 PCT Pub. Date Aug. 13, 1998A solid phase peptide synthesis reactor system and method of operating the reactor are provided. The reactor system includes a basket rotatable about an axis within a housing and a receiver which delivers fluid to, and collects fluid from, the housing. The basket has a perforate side wall against which a resin cake for the peptide synthesis is formed. The reactor and receiver form a loop or circuit through which solutions are circulated. The circulation of the solutions prevents the reactor from flooding so that the basket will not be submerged in solution and allows for the use of less liquid. Thus greater amino acid concentrations may be used. The method includes forming a resin cake of uniform depth on the wall of the spinning basket and spraying the solutions against the resin cake while spinning the basket. The solutions will pass through the resin cake and drain to the receiver to be circulated or recycled through the system or discharged from the system. Before a subsequent solution is introduced into the reactor system, the prior solution is purged from the system to help control exposure time of the peptide to the solutions.

Title: Process for producing liquid pig iron or liquid half-finished products of steel
Inventor: KEPPLINGER LEOPOLD WERNER
IPC: C21B13/14
Filed: 1997-06-26
Abstract: In a method of producing liquid pig iron (43) or liquid steel precursors from charges consisting of iron ore (5) and fluxes, having at least in part a proportion of fines, the iron ore is reduced directly to sponge iron in two or more reduction stages (1, 2) by the fluidized-bed method. The sponge iron is then melted in a smelting-gasification zone (39), with carbonaceous materials and oxygenous gas added; a reducing gas containing CO and H2 is generated, which is introduced into the reducing zones of the reduction stages (1, 2), reacts there, is drawn off as top gas, and supplied to a consumer, where appropriate. In order to achieve uniform reduction of the iron ore with optimum utilization of the reducing gas, in a first reduction stage (1), the iron ore (5) is fractionated into two or more fractions of different grain-size distributions, with the help of the reducing gas; each fraction is reduced with the reducing gas in its own fluidized bed (6, 15); the reducing gas sustaining a first fluidized bed (6), containing the coarse-grain fraction, and separating the fine-grain fraction from it, and additional reducing gas being introduced directly into the other fluidized bed (15); reduced iron ore (5) is withdrawn from both the first and the additional fluidized beds (6, 15), and the fine-grain and coarse-grain fractions reduced in the first reduction stage (1) are reduced further in one or more additional reduction stages (2), that operate in the same way as the first reduction stage (1); from the last reduction stage (2), the fine-grain fraction is fed into the smelting-gasification zone (39) under agglomeration by addition of oxygen, and the coarse-grain fraction is gravity-fed directly into the smelting-gasification zone (39).

Title: Electronic time-measuring instrument with temperature compensation
IPC: H03L1/02
Filed: 1974-10-24
Abstract: In addition to an oscillating circuit constructed as a clock pulse generator (91) and having a temperature frequency response as low as possible, the time-measuring instrument has a further oscillating circuit (92) which has a temperature frequency response deviating therefrom and preferably higher. A counter (98) counts the pulses of this further oscillating circuit and a temperature-dependent signal is formed by arranging for the counter results to be stored in a memory during a period which is essentially determined by a time counter (912) driven essentially by the clock pulse generator (91). Said signal is transmitted periodically to a frequency converter (91) whose output signal is used to correct the signal transmitted by the clock pulse generator to a reduction mechanism (911) which drives the time counter (912). At least some of the said circuit parts consist of CMOS integrated circuits. <IMAGE>
