Abstract: In an air valve for mounting in floors or walls, which is designed in particular for use in ventilation installations which work according to the displacement principle, the aim was to ensure an adequate fresh air supply even under difficult conditions and moreover to ensure optimally uniform distribution of the air flow over the cross-sectional area of the air valve. An air valve which achieves this object comprises one or more grate-shaped elements 2 for mounting in an air admission opening, which elements 2 are designed with inlet and outlet openings 5 and 6 for fresh air. The air valve is characterized in that the inlet openings 5 are connected, via narrow longitudinal inflow chambers 7, to broad longitudinal chambers 8, air flow-deflecting wall parts 4'' of the element 2 being arranged directly above said narrow longitudinal inflow chambers 7 in such a manner that turbulent flows arise in said broad longitudinal chambers 8 before the air is released through the outlet openings 6 to the room. <IMAGE>

Abstract: The invention concerns an interface for a digital electronic control for a gas turbine engine. The interface allows one to gain access to random access memory in the control, wherein data of interest is stored. The data includes information about present operating conditions of the engine, such as component speeds and temperatures, as well as data concerning the health of components. The data is in digital format, but is converted into analog format within the control and transmitted from the control in analog format. The analog data is used to drive a recording device, such as a strip chart recorder, thus allowing information about the engine to be transmitted to a location remote from the engine, in real time.

Abstract: Method for manufacturing form-pressed wood fibre panels, for example door skins, and panels manufactured according to the method. The process starts from a workable, mass produced panel displaying high thermal conductance, for example a so-called MDF-board or chip board. The panel is preheated to a condition where the wood fibres and the binding agent which binds the wood fibres form a pliable or stretchable composition though still in continous panel-like condition. This preheated panel is fed to a form-pressing device where the pressure is relatively slowly increased from 0 to approximately 30 kg/cm<2> during continuing heat supply to a temperature of around 150-200 DEG C. Usually this is attained in connection with door skins after a period of approximately 1,5 minutes. Finally, a form-stable, form-pressed panel is removed from the press.

Abstract: A headbox for stock suspension for a machine for forming a web from the stock suspension. The headbox having an outlet duct formed by a relatively stationary duct wall below and a relatively movable duct wall above. The duct walls converge in the direction of suspension flow to form an outlet slot. The upper duct wall is pivoted at its upstream end to enable adjustment of the clear width, i.e. the inter-wall spacing of the outlet slot. A beam extends across the machine above the movable duct wall. A pressurizable back pressure cushion is disposed between the beam and the movable duct wall. The pressure of the cushion is adjustable for maintaining the desired pressure level exerted by the movable wall on the stock suspension in the outlet slot. A lifting appliance is connected with the beam, but not with the movable duct wall, for adjusting the height position of the beam, which adjusts the width of the pressurized outlet slot.

Abstract: A NOZZLE BOX HAVING NEGATIVE PRESSURE NOZZLES FOR TREATMENT OF MOBILE MATERIAL WEBS An arrangement of nozzles with negative pressure intended for contact-free treatment of mobile material webs (W), comprises a nozzle box provided with a foil face (16; 16, 16T) placed facing the web (W), in connection with which face there are two nozzle slots (17, 18). The nozzle box (10) has a planar carrier face (16), at one of whose edges there is a curved Coanda air-guide face (16R), in connection with which there is the first nozzle (17), at which the initial direction (S0) of its blowing is perpendicular to the plane of the web (W). The Coanda air-guide face (16R) turns the air blow (v1) that comes from the first nozzle (17) towards the direction of the carrier face (16) and of the plane of the web (W) running over the carrier face. In the lateral area of the planar carrier face (16) opposite in relation to the first nozzle (17), there is a substantially planar guide face (16) or guide wing (16T), which extends said planar carrier face (16) continuously. The guide face (16a) is parallel to the plane of the carrier face (16) or, when a guide wing (16T) is used, starting from the plane (16) of the carrier face, to some extent inclined (angle a) towards the web (W). In connection with, or at the proximity of, the outer edge (20) of said guide face (16a) or guide wing (16T) there is a second blow nozzle (18), whose direction (v2) is parallel to the guide wing (16T) of the guide face (16a).

Abstract: A method of, and a system for, selectively delivering still television video with accompanying audio to home subscribers over a cable television system for advertising, promotional or educational purposes. A maximum number of home subscribers can interactively request presentations of their own choosing to be displayed on their home television sets. Only one standard television channel is required for transmission of still video with accompanying audio to serve 300 concurrent users. No equipment is required in the subscriber's home. The video is presented as still frames from one of a number of videodisc players, transmitted over one television channel during the appropriate time interval of 1/30th (or 1/25th) of a second. Such video frames, which may also contain overlaid graphics information, are uniquely addressed to a remote storage device. Unused bandwidth is used for the transmission of up to 300 discrete audio messages. The remote storage device identifies the appropriate video still frame, stores it, combines it with the corresponding audio message and conveys both to the home subscribers' television on a pre-selected channel. By uniquely addressing video frames to the remote storage device, either 30 (or 25) different video frames per second can be conveyed on one television channel to 30 (or 25) different remote storage devices for retransmission to home subscribers. Thus, if a home subscriber sees a given still video frame for 10 seconds, his remote storage device need not be updated for those 10 seconds, enabling the system to transmit 300 (10 secondsx30/second) different video frames to 300 other remote storage devices, thereby serving 300 concurrent users.
