Abstract: A fluid coupling assembly particularly adapted for connecting hydraulic conduits to the ports of a fluid manifold. The coupling comprises a male member (44) which is threadedly connected to the port and which includes tapered locking surfaces (64,62) on the male and female members, respectively, that are in tight frictional engagement when the male member is threaded into the female member (34). An O-ring (60) is positioned in a pocket (58) and disposed between the threads and the tapered locking surfaces to isolate the locking surfaces from hydraulic fluid, thereby ensuring a dry, frictional wedge lock. The O-ring is of a size that permits it to move axially in the pocket. In a modified embodiment of the coupling, there is provided an adjustable fitting which includes a lock nut (76) having a skirt portion (84) that is wedged into the tapered O-ring pocket (86).

Abstract: An acoustic fresh air ventilator is formed in a box (1) in which one or more fans (8, 10) are located. The box is designed to be mounted to a wall (5) with an inlet and/or outlet ducting element (42, 44) extending from the box through the wall. The ducting elements are so arranged as to occupy a minimal space for reducing the size of the hole (70). The box is packed with acoustic packing materials suitably in pieces or bags (30, 32, 36, 38, 40). Conduits (20, 22, 24, 26) between the fan(s) and box sides are preferably formed by the packing material. The fan(s) is/are held in free floating suspension in the acoustic material.

Abstract: The method for boring a tunnel consists in placing an excavation tool (6) at a point of the extrados of the tunnel and in excavating a cavity (13) by imparting the tool an advancement movement having divergent direction with respect to the axis (A) of the tunnel. While the cavity is being filled with concrete, a further cavity is excavated in another point of the extrados and is then also filled with concrete. These operations are repeated until a plurality of voussoirs (14) is obtained which are arranged adjacent to one another along the extrados and give rise to a frustum-shaped vault (15). The soil inside the vault is then excavated for a depth which is smaller than the axial extension of the vault itself, and a subsequent vault (15 min ) is formed having a narrower initial portion internal to the wider terminal portion of the previously executed vault (15).

Abstract: Covering a rigid or hard but pliable, smooth surface with a multilayer masking film having a smooth side and an embossed side is disclosed. The smooth side of the masking film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the masking film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when drop of water is placed between two sheets of glass. The embossed side of the masking film forms microscopic air pockets when rolled upon itself which prevents blocking. This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.

Abstract: A roller (10) used as support, backing or driven roller in winding devices, is composed of an outer cylindrical roller element (24), on which an elastic, flexible intermediate layer (26) of elastomeric material is applied. On the intermediate layer (26), an external roller mantle (33) of thin-wall spring steel is provided that can be deformed in a plane perpendicular to the axis due to the contact pressure of the roll (2) and can be pressed against the outer perimeter of the roll (2). A broad contact region is created, which leads to a lower specific nip pressure and to a smaller package hardness. Channels (27, 28) in the intermediate layer (26) serve to increase the flexibility and cooling.

Abstract: A digital time code (50) is printed in an area (10) of a motion picture film, between the normal analog optical sound track (58) and the picture frames (8), that is exposed along with the sound track (58) from the picture frames (8). Digital audio for the motion picture is stored in a large capacity high integrity archival digital storage system (76). The time codes corresponding to known locations on the film are read as the film is played, and in an anticipatory pass the digital audio signals for these frames are transferred to a fast access data storage buffer (86) which temporarily stores the data before it is converted to analog format for theater play. The time code is read with light that is absorbed by the film dyes produced when the film is developed. Temporary storage of the digital audio signal in the buffer memory (86) accommodates breaks in the film, projector changeover and various time code validation schemes, and allows the digital data source (76) in which the digital audio data is stored to be a relatively slow access high data reliability device such as a digital tape. <IMAGE>

Abstract: The present invention concerns a polymerization catalyst of olefins, said catalyst containing an active chromium compound on an inorganic support. The catalyst in accordance with the invention is prepared by vapourizing a precursor of chromium oxide such as chromyl chloride and allowing the chromium oxide vapour to react with the surface of, e.g., silica gel support material at 160...500 DEG C. A selective binding of the chromium oxide to the support material is achieved by keeping the vapour pressure sufficiently high and the duration of interaction with the support sufficiently long so as to maintain an excess of the chromium compound in relation to the number of available binding sites on the support material. The activity of a catalyst in accordance with the invention even with a very low content of catalytic metal is as high as the activity of a catalyst of an appreciably higher metal content that has been prepared by the methods of the conventional technology.

Abstract: In the method of the present invention for making a non-fat cream cheese product, a fermented skim milk retentate is introduced into a mixing tank provided with agitation means. The skim milk retentate is agitated and transferred through a recirculating loop as dry cottage cheese curd and an emulsifying salt are added to the mixing tank. Agitation and recirculation are continued for a period of time sufficient to provide a dispersion of the dry cottage cheese curd and emulsifying salt homogeneously throughout the retentate. Heating of the dispersion is then started by injecting steam into the dispersion as it passes through the recirculating loop. While the temperature of the dispersion is within the range of from about 70 DEG F to about 150 DEG F (about 21.1 DEG C to about 65.6 DEG C), non-fat dry milk is added to the dispersion. Agitation and heating is continued until the dispersion temperature is within the range of from about 140 DEG F to about 165 DEG F (about 60 DEG C to about 73.9 DEG C). Xanthan gum, as the first gum of a stabilizing system, is then added to the mixing tank. Agitation and heating is continued until the dispersion temperature is in the range of from about 165 DEG F to about 190 DEG F (73.9 DEG C to about 87.8 DEG C). The steam is shut off and salt, sugar and carrageenan, as the second gum of a stabilizer system, are added to the mixing tank. Agitation is continued for a period of from about 1 to about 4 minutes to provide a non-fat cream cheese mix. The cream cheese mix is then homogenized to provide a non-fat cream cheese product.
