Abstract: The invention relates to a chair, in particular a work or office chair, having a seat (16), which can be swivelled in the front region about a horizontal swivel axis (12) and can be altered in inclination, and having a backrest (15), which can be altered inevitably overproportionally in inclination in dependence on the alteration of the inclination of the seat, in which, with increasing inclination of the seat, the backrest executes an additional relative movement in relation to the end of the seat facing it, in which swivel levers (13) are attached on both sides of the seat on supporting arms of the seat frame, the free ends of which swivel levers are mounted fixedly and non-rotatably on the backrest (15) and support the latter, and in which the seat (16) is connected rotatably in its central region to the swivel levers (13). The desired relative movements between the seat, the backrest and the chair frame can only be implemented and varied by the coupling between the seat, the backrest, swivel levers constructed as arm supports or armrests and the chair frame by the fact that, in the region of its front edge offset upwards in relation to the attachment axis of the swivel levers, the seat is mounted rotatably on extensions of the supporting arms so as to be non- adjustable or limitedly adjustable, and that the axis of rotation between the swivel levers and the seat is limitedly adjustable or non- adjustable. <IMAGE>

Abstract: A noncontacting method for sensing torque based on the principle of magnetostriction which induces a primary magnetic flux in a shaft (20) and obtains a torque dependent secondary signal which is a function of a secondary flux is characterized by obtaining an auxiliary signal via such means as an auxiliary core/coil (48/50) and using that signal with appropriate electric circuitry to eliminate non-torque induced variations in the secondary signal. The first embodiment (Figures 5A and 5B) uses the auxiliary signal to maintain the primary magnetic flux at effectively constant amplitude. The second embodiment (Figures 6A and 6B) divides the secondary signal by the auxiliary signal. A third embodiment (Figure 7) employs a plurality of sensors (66A/66B) strategically located around the shaft (20) to eliminate spurious signals which are due to bending stress and shaft misalignment.

Abstract: Mécanisme d'alimentation en feuille de papier à partir d'une pile de feuilles de papier (10) placée sur un plateau (11), les feuilles ayant un revêtement souple ou sensible à la pression. Le mécanisme d'alimentation en feuille comprend un appareil (20a, 72A) d'engagement des feuilles qui distribue la charge sur une surface de la feuille de manière à réguler la pression exercée sur la feuille. L'appareil est déplacé dans une direction pour provoquer le gondolement de la feuille exposée ou première feuille, pour la séparer de la pile et l'enlever. Un mode de réalisation de l'invention utilise une paire de roues d'alimentation (20a), et l'autre mode de réalisation utilise un patin plat (72A) d'engagement des feuilles. Les roues d'alimentation ou le patin sont déplacés, suite au contact avec la feuille exposée, dans une direction parallèle au plan de la feuille pour provoquer la séparation de la feuille supérieure (10a). L'empreinte de chargement n'est pas confinée à une zone spécifique, par rapport aux feuilles se trouvant en-dessous, ce qui évite de marquer ou d'abîmer la feuille se trouvant immédiatement sous la première feuille enlevée par le mécanisme d'alimentation.

Title: Method and composition for decreasing emissions of sulfur oxides and nitrogen oxides.
Inventor: KINDIG JAMES KELLY
IPC: C10L9/10
Filed: 1988-11-30
Abstract: A method and composition are provided for decreasing emissions of sulfur oxides and nitrogen oxides upon combustion of carbonaceous fuel material. In particular, the composition comprises a refined coal, having low ash-forming material and inorganic sulfur content, a sulfur sorbent, a sulfation promoter, and a catalyst for the reaction of sulfur dioxide to sulfur trioxide. Reduced emissions of sulfur oxides are achieved by combusting the composition in an oxygen restricted burner to lessen the effect of sorbent sintering while obtaining other advantages associated with mixing a sulfur sorbent with the carbonaceous material prior to combustion. Nitrogen oxides emissions are reduced by use of an oxygen restricted burner which lowers the flame temperature. Nitrogen oxides emissions are also reduced by lower flame temperatures resulting from endothermic reactions which are undergone by the sulfur sorbent and promoter.

Title: Ultrasonic testing method.
Inventor: FERREIRA NICHOLAS C
IPC: G01N29/22
Filed: 1989-02-22
Abstract: An ultrasonic sound echography technique is disclosed in which echo-masked zones of the workpiece are reduced by utilizing particular orientations of the beam of ultrasonic sound relative to formations in the workpiece. Echo-masked zones result from formations in the workpiece which reflect the ultrasonic sound waves back to the probe and therefore mask the much smaller echoes from anomalies, if any, in the workpiece. Instead of the conventional orientation of the beam, in which the scanning plane in which the beam lies is oriented perpendicularly to formations, the scanning planes are selected so as to be non-perpendicular with respect to such formations and to minimize the amount of masking echoes from the formations.

Abstract: A method for making preforms by vapour phase soot deposition processes is disclosed, whereby an oxidizing atmosphere is used during at least part of the deposition process; e.g. during the deposition of the centre portion of the preform. The oxidizing atmosphere results from supplying oxygen, available to react with the fuel, in an amount which is stoichiometrically in excess of that required to fully oxidize the fuel. This results in enhanced dopant capture, reduced axial inhomogeneities (e.g. of dopant) in the consolidated preform and finished fibre, and an overall stabilization of the deposition process. 
     A method for selecting burner flow rates which optimize the deposition process is also disclosed. 
     The reaction deposition burner used to carry out the process has:- a first passageway (13) and second passageway (15), both of which carry at least oxygen but no fuel; a third passageway (17) to carry at least fuel and oxygen; and optionally a fourth passageway (19) to carry at least oxygen but no fuel, for shaping the flame.
