Title: Production of hydrogen-rich gas
Inventor: JAHNKE FREDERICK C
IPC: C01B3/40
Filed: 1994-10-19
Abstract: This invention relates to the production of hydrogen-rich gas (92) by the partial oxidation of a saturated gaseous hydrocarbonaceous fuel (8) or a mixture of saturated gaseous hydrocarbonaceous fuel and a liquid hydrocarbonaceous fuel in a gas generator (1). In the process, a saturated gaseous hydrocarbonaceous fuel (8) from a subsequent fuel gas saturator (50) is preheated by indirect heat exchange in heat exchanger (43) with a portion of shifted process gas stream (42) from a catalytic water-gas direct shift conversion zone (38) and reacted in said partial oxidation gas generator (1). The process gas stream from the noncatalytic partial oxidation gas generator (1) is quench cooled and scrubbed with water in gas scrubbing column (24) and preheated by indirect heat exchange in heat exchanger (30) with a second portion of the process gas stream (35) from the shift conversion zone (38) prior to catalytically reacting the CO and H2O in the process gas stream in the shift conversion zone (38) to increase its H2 content. The shifted process gas stream is cooled and dewatered in heat exchanger (53) to produce shift condensate which is used to saturate the aforesaid preheated gaseous hydrocarbonaceous fuel feedstream (8) to the partial oxidation gas generator (1).

Patent CZ-321692-A3 (CZ)
Title: Stool, particularly office stool with rotatable seat
Inventor: VOLKLE ROLF
IPC: A47C9/02
Filed: 1992-10-23
Abstract: In a chair, a seat-part support (11) and a backrest support (12), which is adjustable in inclination, are connected movably to effect a synchronous adjusting movement taking place relative to the frame (10). The backrest support engages at its lower end (12a) below the seat-part support and is connected to it for simultaneous movement by means of at least one connecting element. In a transfer movement initiated by the motion of the body of the chair-user, the backrest support is lowered while the seat-part support is simultaneously moved forwards and lowered at least in its rear part (11b). Due to the fact that the backrest support (12) and the seat-part support (11, 111, 211) transmit their movement onto the connecting means and onto one another at points on the connecting means which are spaced apart and are guided on the frame despite being bound to paths which are independent of one another, the backrest support being lowered at least slightly further than the seat-part support in the connection region to the seat-part support during the transfer into the rest position, a high-quality chair is produced in a cost-effective manner, which chair can be transferred into a rest position which is as comfortable as possible. <IMAGE>

Title: Method and device for hardness measuring of materials
Inventor: PETROV DIMITAR G
IPC: G01N3/42

Abstract: The method and the tester can be used for testing and determining the physical and mechanical properties of all hard materials. Measuring hardness is carried out faster with a light portable and simple instrument with which random surfaces are measured, the measured surface considered the basic one. The method consists in applying a static load on a surface, prepared in advance, the material hardness being determined by measuring the critical force Pcr for elastic stability loss of a centrally loaded measuring bar-band on which a highly-hard end piece is hung with a spherical surface and the loading, with gradually increasing force is determined by the maximum value, after the bar-band looses its stability. The device consists of a measuring bar-band (11) with a sphere-surfaced end-piece (12), connected through a dynamometric spring (6), slid on a force-accepting element (7), with a force-assigning button (4) on which over a zero-setting micrometric nut (2) is attached a measuring clock (1).

Abstract: L'invention concerne un dispositif permettant de refroidir une boisson gazeuse stockée dans un contenant (14) et de distribuer une boisson gazeuse non moussée; et un procédé de refroidissement et de distribution d'une boisson non moussée à l'aide du dispositif. La boisson est de préférence de la bière. Le dispositif comprend un corps (16, 110) comportant plusieurs chambres. Une chambre peut éventuellement être prévue pour recevoir des tonnelets de bière. Un dispositif de pressurisation (30) est fixé à un tonnelet (14) de bière afin de maintenir la bière sous pression dans le tonnelet. Une canalisation reçue dans l'une des chambres permet une communication entre le tonnelet et un robinet (18) situé à l'extérieur du dispositif. On fait circuler un mélange refroidisseur constitué d'eau et de glace sur la canalisation (40) de ladite chambre afin de refroidir la canalisation. Un récipient perforé (50) entoure la canalisation afin de la protéger et d'empêcher que les agitateurs soient endommagés par des particules de glace. Au moins deux agitateurs (60, 62) situés dans la chambre recevant la canalisation servent à faire circuler le fluide de refroidissement sur la canalisation. Les agitateurs sont positionnés de manière à faire circuler en continu de l'eau froide sur la canalisation afin de produire un échange de chaleur maximum.
