Abstract: A static mixer comprising a group of deflector elements distributed within a conduit through which a fluid flows in a direction generally parallel to an axis of the conduit. Each deflector element defines a surface which is inclined to the conduit axis such that fluid is deflected by the surface in a direction transverse to that axis. The deflector elements are positioned so as to generate an asymmetric vortex flow such that the intensities of adjacent vortices are different. The deflection elements may be in the form of, for example, asymmetric pairs of tabs, for example spaced apart pairs of tabs of different lengths. The angle of inclination of the tabs to the conduit axis may be adjustable.

Abstract: A self-powered circuit interrupter arrangement for interrupting current in a circuit path uses a current-blocking component to ensure that an insufficient amount of accumulated power for actuating and completing interruption of the circuit path is not misused in an unwarranted attempt to interrupt the current path. The arrangement includes a current inducer circuit for providing a current signal having a magnitude corresponding to the current in the circuit path and a power supply operating from the current signal to provide a voltage signal of a predetermined value relative to common. A trip command circuit, in response to a fault detected in the circuit path, sends an electrical signal commanding that the circuit path be interrupted by using the voltage signal. The electrical signal is sent to an electrical latch located electrically in series with a coil of a solenoid mechanism.

Abstract: A sheet material support system includes a floating box having upwardly extending leading edges defining a plane extending parallel to said base in which sheet material is caused to conform to by applying downward pressure to it and causing the sheet material to become tautly drawn over the box upper edges. The system includes a locating block and clamps which allow frames to be located uniformly along X and Y coordinate axes so that successive frames can be loaded in uniform registration in the system.

Abstract: An isolator assembly is disclosed for supporting internal component inside a pneumatic underground piercing tool having an axial body propelled by impact forces of a striker responsive to the application of compressed air. The isolator assembly is comprised of an isolator housing mounted to the body of the piercing tool in a manner that allows relative axial movement between the body and the isolator housing. The internal components to be protected from the impact forces are mounted on the isolator housing. An elastomeric member is positioned to permit the isolator housing and internal components mounted thereon to move resiliently in the axial direction relative to the body of the piercing tool during each impact of the striker.

Abstract: A guard for attachment to the end of a cylinder of compressed gas comprises a cylindrical portion of diameter approximating the diameter of the intended cylinder and a pair of flanges extending outwardly from the cylindrical portion and contiguous therewith and defining between the flanges a space through which access can be obtained to the interior of the guard for observing and operating upon the valve arrangement of the cylinder. The cylindrical portion is clamped around the cylinder by drawing together the flanges by a pair of bolts extending across the flanges with spaces for defining the minimum space between the flanges. Openings in the cylindrical portion provide handles and access to the interior. The end of the cylindrical portion is open. A chain for supporting the guard and cylinder is attached to the guard and hooks are mounted on the flanges for receiving the hose from the cylinder.

Abstract: A pipe plugging tool for use in cutting and then soldering a fitting to a pipe includes a shaft, sleeve, compressible plug and nut arranged so that the nut can be rotated to axially compress the plug so that it radially expands into contact with the inner surface of the pipe. A stop member can be removably and adjustably positioned on the sleeve to set the location of the plug relative to the end of the pipe so that the nut is exposed when the fitting has been completed and so that the plug is spaced from the soldering heat sufficient distance to prevent degradation of the plug. A bag including a zipper and hook loop connecting fabric can be wrapped around the pipe prior to cutting. The bag has sleeves through which the hands of the operator can pass so that the cutting and plugging can be completed inside the bag and any escaping water collected at the bottom of the bag.

Abstract: This invention relates to an improved handle for attachment of a pair of control cables to a model airplane for control of the latter during flight. The handle consists of a gripping portion which has adjustable parallel bolts extending perpendicularly to the longitudinal axis of the gripping portion. Connected between the parallel bolts is a crossbar to which is attached a pair of slidable nylon guide blocks. Through the adjustment of the guide blocks along the crossbar, the cables to the airplane may be varied in length to properly stablize the plane during flight.

Abstract: Roasted and ground coffee is contacted with steam and the evolved vapors are condensed and partitioned in two separate and successive operations with liquid glyceride material such as a vegetable oil. By the use of appropriate partitioning parameters both the second glyceride and water phases have been found to have a smooth, buttery flavor useful for enhancing soluble coffee. The second glyceride phase may be combined with natural grinder gas, added to liquid coffee extract and then dried to produce an aromatized soluble coffee product.
