Abstract: LEAK DETECTOR AND LOCATOR UTILIZING TIME    DOMAIN REFLECTOMETRY AND SAMPLING TECHNIQUES             Abstract of the Disclosure A leak detector and locator utilizes an electrical cable disposed in proximity to fluid carry-ing pipes or other area wherein a leak may occur. Pulses are applied to the cable and the reflected waveform is analyzed to detect changes in the charac-teristic impedance of the cable caused by fluid pene-trating the insulation of the cable.  A different portion of the waveform corresponding to a different point on the cable is sampled after each pulse is generated and stored until the entire waveform has been sampled and stored.  Subsequent samples of the waveform are compared with the stored waveform and a leak is indicated if the subsequently sampled waveform differs from the stored waveform by a predetermined amount.

Title: Method for filtering a heat-softened stream of plastics material, and a filtering apparatus for executing the method
Inventor: PETSCHNER GOETZ
IPC: B29C48/03
Filed: 1988-10-28
Granted: 1994-04-05
Abstract: ABSTRACT OF THE DISCLOSURE In a filtering apparatus for extrusion machines, a stream of heat-softened plastics material arrives, via a flow conduit in a filter housing, at an outlet, and thereby permeates replaceable filters which are carried by a slide which is temporarily slid out of the stream of plastics material. For this, the slide comprises two chambers, forming flow conduit sections and arranged spaced in tandem in the direction of displacement, both of which are closed by filter plates; the flow conduit sections being, at a specified position of the slide in the filter housing, internally in flow connection via, in each case, a port, with the outlet conduit in the filter housing and, externally, via the filter plates, with the inlet conduit or with a backflow conduit in the filter housing. As a result of these steps, apart from a filter replacement, a reestablishment of the specified through-flowability of the filter means by a backflow flushing is possible without thereby having to interrupt the flow of heat-softened plastics material either in the one or in the other case.

Abstract: ALL WELDED SOUND ISOLATION FLEXIBLE CONNECTION     ABSTRACT A flexible pipe joint having an annular housing with a central cavity in which a nipple is partially submerged.  The nipple has a flared end on the submerged portion thereof.  An elastomeric ring, internally contoured spherically with reference to a common center point spaced from the flared end and located on the longitudinal axis of the point is adhered about its outer surface to the inner surface of the flared end. An elastomeric body having an assembly of embedded concentric spherical rings is adhered to the outer surface of the flared end.  The spherical rings are contoured and positioned symmetrically with respect to the common center point.  A flange (42 or 144, 146) is welded to the nipple at the end opposite the flared end.

Abstract: Abstract of the disclosure Moldings  composed  of  cordierite  and  a  process  for producing them For producing moldings composed of cordierite, a batch, which gives the composition of cordierite and contains clay and/or kaolin as well as soapstone and/or talc and also water and an organic aid, is subjected to shear mixing. For this purpose, the batch is placed between 2 bodies, which are at a small distance and move relative to one another, and at the same time the batch is sub-jected to a shear stress.  Preferably,  the batch is filled  into  the  gap  formed  by  2  almost  touching cylindrical shear rollers which rotate at different speeds or run in opposite directions. The batch is then deformed to give a molding, and the molding is fired until the cordierite phase is formed.          Cordierite bodies of very low coefficients of thermal expansion (for example at most 1.1 x 10-6/°C in all three spatial directions) can be obtained.

Abstract: DIGITAL VISUAL AND SENSOR SIMULATION SYSTEM FOR GENERATING REALISTIC SCENES ABSTRACT OF THE DISCLOSURE A system using a ray-tracing algorithm and a hierarchy of volume elements (called voxels) to process only the visible surfaces in a field of view. In this arrangement, a dense, three-dimensional voxel data base is developed from the objects, their shadows and other features recorded, for example, in two-dimensional aerial photography. The rays are grouped into subimages and the subimages are executed as parallel tasks on a multiple instruction stream and multiple data stream computer (MIMD). The use of a three-dimensional voxel data base formed by combining three-dimensional digital terrain elevation data with two-dimensional plan view and oblique view aerial photography permits the development of a realistic and cost-effective data base. Hidden surfaces are not processed. By processing only visible surfaces, displays can now be produced depicting the nap-of-the-earth as seen in low flight of aircraft or as viewed from ground vehicles. The approach employed here is a highly-parallel data processing system solution to the nap-of-the-earth flight simulation through a high level of detail data base. The components of the system are the display algorithm and data structure, the software which implements the algorithm and data structure and creates the data base, and the hardware which executes the software. The algorithm processes only visible surfaces so that the occulting overload management problem is eliminated at the design level. The algorithm decomposes the image into subimages and processes the subimages independently.

Abstract: 7.  ABSTRACT OF THE DISCLOSURE:    A rotary compressor is disclosed which is equipped with a bypass hole for bypassing a fluid under compression to the intake side and the capacity thereof is controlled through opening and closing of the bypass hole with a piston which is operated via a control valve, whereby the bypass hole is opened at or in the vicinity of a discharge port of the compressor and the capacity of the compressor is made to be controllable in the range of one hundred to substantially zero percent.  By the application of such a rotary compressor to the compressor for an air conditioner, capacity control in the range of about zero to 100% of discharge quantity can be accomplished so that. it becomes possible to obtain cooling capability which is in response to the heat load.
