Title: Method of and apparatus for testing a wire rope
Inventor: VAN DER WALT NICOLAAS T
IPC: G01N27/82
Filed: 1987-03-19
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE            A wire rope tester which can detect broken wires, area reductions, or wire contact irregularities. The tester includes two permanent magnetic stacks which produce axial adjacent and opposed DC magnetic fields which magnetise the rope. Broken wires are indicated by flux variations when the flux density is at saturation; area reductions are related to flux variations; also at saturation flux density; and wire contact pattern changes produce detectable eddy current flux variations when the flux density gradient is constant.

Title: Elements with opening
Inventor: SCHEIWILLER ROLF
IPC: E02D27/00
Filed: 1987-11-16
Granted: 1992-05-26
Abstract: ABSTRACT            The elements with opening are preferably combined into a lawn plate with openings, whereby these elements with opening are impressed. The plate comprises in its longitu-dinal direction an indentation whereby a bulge is provided on one side and a narrowing on the other side with a width corresponding to the one of the element with opening, resp. of the paving stone.            The individual elements with opening correspond in their dimension and their configuration to paving stones so that these paving stones can be seamlessly adjoined to the element with opening. When the elements are laid without adjoining paving stones there exists on the one hand an interlocking of the plates as well as a pleasant configura-tion of the latter, whereby the arrangement of the indivi-dual elements with opening having different dimension can vary within large limits.            In another example of execution in which elements with opening are laid round a tree, the element with opening is in two parts connected together by a traverse having a smaller thickness. The two lower, lateral edges of the lower part form part of a sector and a distance piece is provided at the upper edge on both sides of the upper part, the outer edges of this distance piece enclo-sing the same angle than the lower, lateral edges. These elements with opening can be laid in a straight configuration or in a circle round a tree.            Both elements provide for pleasant configurations and they render possible a seamless transition to a pavement having  corresponding configuration  and  dimension.

Title: Sealing and dynamic operation of a liquid ring pump
Inventor: SOMARAKIS JOHN
IPC: F04C19/00
Filed: 1988-03-15
Granted: 1993-08-10
Abstract: ABSTRACT     Improvements  in  the  sealing  area  and  dynamic operation  of  liquid  ring  pumps.    The  sealing improvement  involves  providing  aspirating  means between the cone inlet and the fluid adjacent the shaft on the inboard or high pressure side of the sealing area.  In operation, the high pressure fluid that would tend to leak past the seal in prior art to contaminate  the  bearings  or  create  a  potentially dangerous gas explosion is harmlessly aspirated off into the gas being drawn into the pump.  Further, in doing so, the sealing properties of the pump seal are enhanced.    The  dynamic  improvement  is  directed particularly to duplex liquid ring pumps and calls for the rotor blades on one side of the central partition to be offset or out  of phase  from the mirror-image rotor blades on the other side of the partition.   In this manner, the offset rotor blades in  the  adjacent  pump  chambers  have  a  counter balancing effect to improve the operation of the pump be reducing the amplitude of the dynamic pulsations resulting  in  a  pump  with  smoother  operation  and longer life.

Title: Self-blunting needle assembly and device including the same
Inventor: SAHI CARL R
IPC: A61M5/178
Filed: 1988-09-23
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE        A self-blunting needle assembly comprises a hollow needle, which may be of conventional construction having a needle mouth and a needle shank terminating in a puncture tip, has mounted within it a blunting member including an elongate probe which slidably fits within the bore of the needle shank.  The probe terminates in a distal tip which is initially positioned short of the puncture tip of the needle so as not to interfere with injection of the needle either into a patient or into a connecting device.  After injec-tion, the blunting member is advanced to an extended posi-tion in which its distal tip protrudes beyond the puncture tip, thereby effectively blunting the needle. This protrud-ing probe disables the needle from a re-use and blunts it sufficiently to prevent or greatly reduce accidental needle-stick wounds.  A mechanical extension member, such as a pin or fluid flowing through the needle may be used to advance the blunting member to its extended position.

Abstract: ABSTRACT      In an air cooled overhead valve internal combustion engine, a metal gasket plate is disposed between the cylinder portion and the cylinder head.  The metal gasket plate includes apertures for receiving the push rods therethrough and guide tabs disposed on opposite sides of the push rod for controlling lateral displacement of the push rods.  The metal gasket plate includes adjacent annular stepped portions extending alternately in opposite directions out of the plane of the gasket plate adjacent the periphery of the aperture.  Cylinder head bolts are received through the cylinder head and threadedly received in the cylinder portion and pass through the metal gasket plate.          Dish shaped spring washers are provided between the cylinder head and the underside of the head portion of the cylinder head bolts.  The cylinder head bolts are tightened into the cylinder portion sufficiently to partially compress the spring washers such that the spring washers maintain substantially constant compressive force between the cylinder head and the cylinder portion on the metal gasket plate throughout thermal cycling of the engine.  Leakage of the cylinder head gasket which might otherwise occur as a result of temperature induced expansion and contraction of the engine is thereby avoided.

Granted: 1996-01-30
Abstract: Composites of materials in which the matrix material does not spontaneously or readily wet the disperse phase and in which the volume fraction of the disperse phase is less than that formed in a packed bed of dispersate particles can be made effectively by an indirect method of infiltrating a packed bed of dispersate particles, using pressure or other mechanical force as needed to overcome poor wetting and form an intermediate concentrated composite.   The concentrated composite  is  then mixed with  additional  matrix-forming material to produce the finally desired composite.   The technique  is  particularly valuable  for  composites  with ceramic dispersates and metal or alloy matrixes.

Abstract: POWER TAKE-OFF CONTROL APPARATUS             Abstract Power take-off control apparatus which automatically shifts a vehicle speed range transmission into neutral whenever a power take-off mechanism is engaged to prevent accidental engagement of a drive gear while the power take-off mechanism is in use.  A piston is moved in response to fluid pressure to shift the speed range transmission between high and low speed gear ranges.  The power take-off mechanism is engaged in response to fluid pressure from a control valve. Whenever fluid pressure is applied to engage the power take-off mechanism, the fluid pressure moves the piston to an intermediate neutral position to disengage the vehicle drive.
