Abstract: SONIC APPARATUS AND METHOD FOR DETECTING THE PRESENCE OF A GASEOUS SUBSTANCE IN A CLOSED SPACE               ABSTRACT OF THE DISCLOSURE   A method and apparatus for detecting the presence of a gaseous substance within a space bounded by an enclosure utilizes the fact that sound is not transmitted through a vacuum and is transmitted through the material of the enclosure. A sonic wave transmitter and a sonic wave receiver are engaged with the material of the enclosure and separated by the space. Using the calculated arrival times and/or amplitudes for the soundwave portions through the space and through the material of the enclosure, it can be determined whether a soundwave portion has passed through the space and thus a leakage of gaseous substance into the space above a threshold amount has taken place.

Abstract: Abstract of the Disclosure An apparatus is disclosed for forming an intermittent stream of fluid which is directed onto a target.  Pressurized fluid from a manifold passes through a bore or similar stream-forming device which faces the target. Extending over the stream path, in cantilevered fashion, is a resilient reed which is operably associated with a plunger.  When the plunger is in a retracted position, the cantilevered reed does not interfer with passage of the stream.  When the plunger is extended, however, the free end portion of the cantilevered reed is urged into the path of the stream and prevents the stream from striking the target.  A barrier is provided for containing the disrupted stream.

Abstract: ABSTRACT OF THE DISCLOSURE         An expansion dowel assembly is made up of an axially elongated generally cylindrically-shaped dowel body and at least one wedge-shaped expansion member formed monolithically with the dowel body.  The dowel body has a first or leading end which is inserted first into a borehole within which the dowel body is to be anchored and an opposite second end.  A severable web connects the expansion member to the first end of the dowel body.  Before insertion into a borehole, the expansion member projects outwardly from the exterior surface of the dowel body.  When the expansion dowel assembly is inserted into a borehole, the web is broken and the expansion member, now separated from the dowel body, is displaced away from the first end within a wedge-shaped recess in the exterior surface of the dowel body.  When a load is attached to the trailing end of the dowel body tending to move it opposite to the insertion direction, the expansion member becomes wedged between the borehole surface and the base of the recess in the dowel body.

Abstract: ABSTRACT     A protective propane tank valve housing assembly for motor vehicle propane fuel tanks, has an elongated propane fuel tank with a set of controls disposed on the tank and spaced apart in a direction lengthwise thereon.  A casing has side and end panels, which define a side opening of the casing.  A casing cover is pivotal connected at a first end panel, and swingable between a closed position in which the casing cover lies adjacent, and covers, the side opening of the casing, and an open position outwardly pivoted from the closed position.  The casing cover further has a first flange extending from a second end of it.  A second flange extends from the second end panel of the casing, and mates with first flange when the casing cover is closed.  Such an arrangement allows a lock to extend between the first and second flanges, to lock the casing cover in the closed position.  In a typical installation, the casing is already provided on the fuel tank, and the casing cover and the second flange, are mounted on brackets which are connected to the casing.

Abstract: Abstract of the Disclosure Disclosed is a process for the preparation of a printed draw-formed body having a printed image on the side wall thereof by subjecting a prior-printed blank to draw-forming, which comprises converting an image of an original to be printed to a digital image element signal on a rectangular coordinate, converting the image element signal on the rectangular coordinate to an image signal or image signals on a corresponding conversion coordinate formed by developing the rectangular coordinate to an annular plane having an area substantially equal to the area of said rectangle, reading image element signals on the conversion coordinate in order of the coordinate, photo-electrically converting the read image element signals to a printing plate for the blank and printing the blank by using the formed printing plate.     According to this process, since digital coordinate conversion is performed while compensating anisotropy of the elongation of the metal blank, an improved printing precision can be obtained in a draw-formed body.
