Abstract: A tape cartridge adapted to utilize the read/write head(s) in a disc drive to read data from and/or write data onto the tape. The tape cartridge includes a portion (A) which has a size and shape which enables it to be inserted into the disc drive to locate a portion of the tape at a predetermined location suitable for transferring data with the disc drive head(s). The tape cartridge includes: tape media (20); a means (22,23,26) to register the tape media (20) with respect to the read/write head(s) of a disc drive; spool or reel means (51,52) for storing that portion of the tape media which is not contained within the portion (A) which fits into the disc drive; and a means (21) for feeding the tape media past the read/write head(s) in the disc drive. The tape cartridge includes a linkage (2,3) which enables it to utilize the disc drive spindle motor to feed the tape. The tape cartridge also includes a clutching mechanism (21C,24C) associated with each spool or reel (51,52) which is adapted to drive the spool (51,52) to wind tape (20) thereonn and which is further adapted to slip so as to allow the spool (51,52) to rotate in the opposite direction while tape (20) is being unwound.

Abstract: In wet removal of sulphur dioxide from flue gases, using an absorbent suspension containing limestone, a) sulphite is oxidised to sulphate in the bottom of an initial-stage absorption in the pH range from 4 to 5 by passing air to the suspension and coarse-grained gypsum is removed from the system as a solids-rich suspension, b) in a final-stage absorption in the pH range of about 6, the sulphur dioxide of the flue gas is bound as sulphite by the absorbent suspension and the latter is collected separately in an outlet and recycled to the absorbent suspension stock tank, c) the water losses of the initial-stage absorption are compensated by the overflow of the absorbent suspension, d) the water losses of the final-stage absorption are compensated by the washing water from downstream demisting, the final-stage absorption then being carried out spatially next to, but above the initial-stage absorption and directly above the absorbent suspension stock tank.

Abstract: A system for the control of a fluid flow control valve (14) which controls the supply of fluid to an actuator (12) to control the movement of a component such as a tractor implement hitch (10,13) in response to a selected operating parameter such as hitch position or draft force. The system enables the desired value of the selected parameter to be set (S) and this desired value is compared (P,D)with the actual sensed value of the parameter to provide a parameter error signal (E) . A start-up control function (SUC) is provided to improve the initial speed of response of the system. The start-up control function is arranged on each detection of a parameter error signal to apply a start-up signal to the valve to initiate movement of the component and, if no movement results, to increase the start-up signal until movement of the component is detected (20,25) whereupon the increase in the start-up signal is stopped and the magnitude of the signal applied to the valve is dependent on the parameter error signal so as to tend to reduce the error signal to zero.

Abstract: Pour transvaser le toner (21) d'un bac à réserve (20) dans le réservoir prévu à cet effet, on crée dans ce dernier une dépression à l'aide d'un ventilateur aspirant. Le réservoir de toner est relié via un tuyau souple à un bec aspirant insérable dans le bac de transfert. Ce bec comporte un tube intérieur (29) en communication avec la conduite souple, et un tube extérieur (31) qui enveloppe totalement avec un espacement le tube intérieur (29), est ouvert à l'air libre dans sa partie supérieure et présente dans sa partie inférieure des ouvertures d'entrée (33) du toner. L'air circulant aspire le toner à travers ces ouvertures d'entrée (33). Le réservoir de toner est lui-même divisé en un espace de dépôt et un espace d'aspiration séparés par un filtre. Sous l'effet du courant d'air circulant, le filtre se voûte. L'inversion de cette voûte fait sauter le toner (21) qui y adhérait et qui tombe alors dans l'espace de dépôt.

Abstract: The invention provides an electro-optic welding lens assembly (2) for use in a welder's helmet (1) or protective eyeshield. It includes at least one liquid crystal filter element (14) adapted to be controlled with regard to its light transmission as well as a control means (11, 12, 13) for changing the rate of light transmission of the liquid crystal filter element (14). The control means comprises a first manually adjustable control circuit (13) operating independently of the amount of light falling on the lens assembly (2) and including means to adjust the rate of light passing through the liquid crystal filter element (14). Further, there is provided a second auto­matically operated control circuit (11) operating in relation to the amount of light falling on the lens assembly (2). The second control circuit operates only within a range of light intensity above a predetermined treshold value to limit the rate of transmission of light passing through the liquid cry­stal filter element (14). Thereby, the second control circuit (11) overrides and compensates, respectively, the effect of the first control circuit (13) in the range above said treshold value of light intensity falling on the lens assembly (2), with the effect that the lens assembly can not be opened too much if harmful light rays are present in the ambient.

Abstract: In a continuously cast piece of austenitic stainless steel having a large amount of Mo, segregation of alloy elements such as Mo and Cr is caused at the center part in the thickness direction of the slab, and the σ-phase is precipitated during the step of cooling the cast piece. When a heavy plate or hot coil is prepared from this cast piece as the starting material, cracking occurs in the hot-working step and the corrosion resistance of the final product is degraded. According to the present invention, at the cast piece-­forming step, the super-heating degree of the molten steel is controlled to at least 25°C, whereby the isometric ratio is controlled to below 25%. When the heating times at the soaking and hot rolling treatments and the conditions for annealing the obtained steel sheet are controlled, the pitting resistance of the steel plate is greatly improved and cracking is prevented at the hot-working step.
