Abstract: The shaft support (7) possesses a horizontal bar (14) which joins the vertical elements (15, 16) together. The vertical elements are provided with a resilient weak point (25, 26) which acts as a pivot joint and makes it possible, if the shaft (6) has to be changed, to fold out the vertical elements (15, 16) and hence to pull the locking cams (17, 18) away and outward from the upper shaft longitudinal side (13a). This provides a shaft support system which safely and reliably supports a shaft (6) without imposition of clamping forces and also makes shaft replacement possible in a very short time without the use of tools.

Abstract: Load transmitting means for electromechanical measure­ment of forces and weighing comprising a load measuring body (32) permitting horizontal and angular changes of a load car­rier supported by devices according to the invention. At each end of the measuring body having plane ends there is a trans­mitting unit (37, 38) in the form a cylindrical body with its longitudinal axis parallel to the end plane of the measuring body and with cylinder surfaces facing the measuring body and having single-curved, circular forms. 
     The longitudinal axes of the cylindrical bodies - oscil­lation pieces - are turned at an angle of 90° relatively close to one another so that they transmit movements in the plane parallel to the end plane of the measuring body in each their direction parallel to their longitudinal axis and support at the same time the measuring body transversely of their longi­tudinal axis. In this way the load measuring body can move merely parallel to its longitudinal axis, i.e. in parallel with the direction of the measuring load. Guide means for the oscillation pieces belong to the device so that they cannot slide over the surfaces as well as split washers (51, 55, 56) with a central hole. The washers can be turned aside in their plane, and in this way it is possible to take out the measur­ing body and the oscillation pieces from the transmitting de­vice even after they have been mounted below a load carrier.

Title: Electric arc generating device.
Inventor: DOOLETTE ASHLEY GRANT
IPC: B05B7/22
Filed: 1989-09-13
Abstract: An electric arc generating device including, a first electrode (1) and at least two further electrodes (2, 3, 4). A source of electrical power (11) is connectable to said electrodes so as to cause an arc to burn between the first electrode and one of the further electrodes. The distribution of power within the zone of the arc is controlled by repetitively changing the path of the arc. That is, one root of the arc may remain attached to the first electrode, whereas attachment of the other root is transferred between twor or more of the further electrodes on a repetitive basis. The timing and extent of each change may vary according to circumstances of use. The changes in arc path are due at least in part to repetitive modification of the influence of the power source on one or more of the further electrodes, but variation of the flow rate of gas/material (7, 9, 10) through the arc zone (6) can be another controlling factor.

Abstract: The invention relates to a method for measuring the concentration of a plurality of components of a gaseous mixture,   - in which the concentration of a component A exceeds the concentrations, to be measured, of other components to such an extent that the measurement of the concentration of the other components is influenced, - in which light from a light source having a continuous spectrum transilluminates a measuring gas cell which is filled with the gaseous mixture, and - in which the intensity of narrow and broad absorption lines in the light leaving the measuring cell is used to determine the concentration of the components with the aid of a spectrometer and detector, and - in which the component A has a very narrow absorption line spectrum.   It is the object of the invention to propose an improved method in which the effect of an interfering component present in high concentration is eliminated. The object is achieved according to the invention when an auxiliary gas cell which contains the component A is inserted into the beam between the light source and detector.

Abstract: Cet élément de blocage comporte une soupape de commande (1) et une soupape de distribution (2) qui ont toutes deux des positions de commande. Une des positions de commande de la soupape de distribution (2) est réglée par la pression agissant sur une surface (36) du piston de la soupape de distribution (31), cette pression dépassant une valeur prédéterminée d'une pompe basse pression (20) à fonctionnement dépendant de la vitesse du moteur. La soupape de distribution (2) n'entre en contact qu'avec le moyen de pression déplacé par la pompe à basse pression (20) et commande la grande surface frontale (40) et la surface annulaire (41) du piston (38) de la soupape de commande, qui a la forme d'un piston à gradins. Lorsque, si on a passé une grande vitesse et que la vitesse du moteur dépasse un seuil prédéterminé, on déplace la soupape de changement de vitesse (7) sur la position correspondant à une petite vitesse, la soupape de distribution (1) empêche l'activation du dispositif d'actionnement (15) pour la petite vitesse. Simultanément, le dispositif d'actionnement (16) pour la grande vitesse reste soumis à une pression de commande, de sorte que la grande vitesse reste engagée.

Abstract: A method of directly producing N-(3',4'-dimethoxycinnamoyl)anthranilic acid readily in a high yield without being accompanied by the formation of difficultly separable by-products, which comprises either reacting 3',4'-dimethoxycinnamic acid with anthranilic acid in an aprotic polar solvent in the presence of both a specified inorganic salt and an iminium salt which can be quantitatively prepared from dimethylformamide and an inexpensive acyl halide reagent, or reacting 3',4'-dimethoxycinnamic acid with the iminium salt and then with an anthranilic acid-inorganic salt complex which is a new compound not found in any literature. This method makes it possible to produce an objective compound at a high yield without the necessity for using a basic substance or an amine in a large amount sufficient for neutralizing an acid to be generated as a by-product in the condensation unlike known methods, and is scarcely accompanied by the formation of by-products, especially those which are difficult to separate.

Abstract: In a sieve drum device with, arranged on the front end, a fan (6) for creating the suction draught through the sieve drum surface, a dynamic pressure cover (13) is usually arranged in front of the sieve drum jacket (5). This dynamic pressure cover creates in the dynamic pressure space in front of the dynamic pressure cover (13) the dynamic pressure necessary for the uniform treatment of the material web (10). In order to be able optimally to treat material webs (10, 10') of different width on the sieve drum (5), the dynamic pressure cover (13) is either completely removable in the region of the narrower material width (10') or provided with an opening mechanism (22-26), or the dynamic pressure cover (13) is assigned an additional parallel sieve cover (14) which is displaceable towards the dynamic pressure cover. The holes (17, 20, 21) of the dynamic pressure cover (13) and sieve cover (14) are arranged in relation to one another in such a manner that, on displacement by approximately one hole spacing, the majority of the holes of the dynamic pressure cover can be closed by the webs of the holes of the sieve cover, in order to be able to dry the material in the remaining part.

Abstract: A two-side video disc is manufactured by laminating a top side face disc having a HDTV video signal with red color signal component recorded and a back side face disc having a HDTV video signal with blue color signal component recorded at a position corresponding to the recorded signal on the top side face. Visual end marks are formed at the respective ends of recording tracks of the top side face and back side face discs. The two discs are laminated so that the positions of the end marks coincide with each other. This minimizes deviation in timings between the reproduced signals from the two sides of the disc to reduce significantly the memory capacity of delay means.
