Abstract: MULTI-TUMOR (SAUSAGE) TISSUE SLICES AND METHODS OF PRODUCING SUCH SLICES AND OF TESTING THE TISSUES IN SUCH SLICES                     Abstract of the Disclosure A plurality of tissue rods have a relatively great length (e.g., 10 mm) and a relatively small cross-sectional area (e.g., 1 mm2) in a transverse, preferably perpendicular, plane.  The rods may constitute (1) an array of well characterized neoplasms of varying histogenesis and degrees of differentiation and a spectrum of normal tissues, (2) groups of tissues with related types of tumors and/or normal tissues, (3) tissue groups of defined classes and/or tissue groups as control samples and/or (4) representative tissue samples from defined patient populations.  The rods are disposed in substantially parallel relationship in a casing having suitable dimensions (e.g., 2 cm x 3 cm).  The casing may be formed from a suitable material such as portions of small intestines of small animals such as rabbits and may be stretched, preserved and stored.  The casing may be tightly wrapped around the rods and bound as by a fine thread.  The ends of the rods and the casing may be trimmed to insure that the rod ends are exposed.  When the rods are disposed in groups in the casing, septums in the casing may separate the different groups.  The thread is removed and the combination is embedded as in paraffin.  The paraffin block is then sectioned to produce one thousand (1000) or more substantially identical slides.  A single drop of a suitable material such as a hybridoma supernatant which may contain a monoclonal antibody may then be applied to individual ones of the slides to immuno react with the sectioned rods in the slides.  The staining intensity of each rod section indicates the relative amount of the immuno reaction between the hybridoma supernatant and such rod section.

A connection layer for attaching an external electrical conductor is deposited on the isolation layer.  The connection layer may be aluminum, chromium or a layer of copper, provided a copper layer is covered with one of silver, aluminum or a thin layer of nickel, preferably covered with aluminum.

Abstract: LINK-TYPE ROTARY COUPLING                        ABSTRACT           A link-type rotary coupling for use in a coupling for transmitting torque between rotatable drive and driven means while accommodating angular misalignment between their rotational axes, including a plurality of links interconnect-ing the drive and driven elements.  The improvement resides in that the link comprises an axially stiff body adapted to accept both tensile and compressive loads applied tangentially between the drive and driven elements.  A first elastomeric bearing is provided for connecting a first end of the body to the drive element to permit the body to pivot about at least one axis while undergoing elastic compression during application of tension to the body.  A second elastomeric bearing is also provided for connecting a second end of the body to the driven element to permit pivotal movement of the body about a second axis parallel to the previous said one axis.  At least a selected one of the first and second elastomeric bearings also permit pivotal movemnt of the body about a third axis orthgonal to either the first or second axis.  The selected elastomeric bearing is adapted to undergo elastic shearing during the pivotal motion about both the orthogonal axes and to undergo elastic compression when the body is subjected to tension while rotating about misaligned axes to accommodate the link motion necessary to effect a substantially constant velocity connection between the rotatable members.

Title: Method and apparatus for priming an ink jet pen
Inventor: NEVAREZ RUBEN
IPC: B41J2/175
Filed: 1988-02-26
Granted: 1992-04-28
Abstract: ABSTRACT    A method and apparatus for priming a thermal ink jet pen is disclosed.  Using an ink reservoir fabricated of a foam material, forced air pressure applied to the foam causes ink therein to flow through the foam and into the printhead.  A holder for a rubber air bladder operates in conjunction with a pen cartridge holder whereby an air hole in the reservoir container is aligned with the bladder.  Manually pushing the cartridge against a spring results in a squeezing of the bladder, causing air to exert a compression-like pressure directly on the foam reservoir.

Title: Method for restraining vibration of a floor and apparatus therefor
Inventor: SATO TAKANORI
IPC: E04B1/98
Filed: 1988-04-26
Granted: 1992-05-26
Abstract: Abstract The present invention provides a method of restraining vibration of a floor and an apparatus therefor.  According to the method, a reservoir is attached to the floor which is supported from structural members of a floor structure and fluid is put in the reservoir.  Geometry of the reservoir and depth of the fluid is determined so that sloshing natural frequency of the fluid coincides with a natural  frequency of the  floor in a  same direction.  The vibration restraining apparatus according to the present  invention  is  provided  with  a  reservoir  wherein  a prescribed amount of  liquid  is retained.  Natural  sloshing frequency of the liquid in the reservoir is generally equal to a natural  frequency of the floor structure.   As the  floor vibrates  because  of  vibration  of  the  floor  structure  or vibrational source on the floor, vibrational energy of the floor is  transmitted  to the  liquid  and  causes  sloshing  thereto.          Because the sloshing natural frequency is generally equal to the natural frequency of the floor, vibrational energy of the floor is almost totally transmitted to the liquid.   Consequently, vibration of the floor is restrained.

Abstract: CENTRIFUGAL STARTER SWITCH APPARATUS  Abstract Of The Present Invention A centrifugal actuator for an induction motor mounted on a motor shaft for operating a switch in the start winding circuit.  A U-shaped base member is secured to the shaft with an elongated base extended diametrically of the shaft and with side members extending parallel to the shaft.  A pair of oppositely disposed U-shaped weights are pivoted in hinges on the side members creating linkage and aligned pivot arms projecting around the hub body portion.  The arms pivot on each other within confining walls of the hub.  The weights under centrifugal force move the hub and actuate the switch.  Springs on the opposite sides of the hub are secured to one end to the side members and at the other end to the hinges and extending diametrically over the body of the hub, said springs extended with movement of the weights to move toward the pivot point of the arms.  The springs reset the actuator at a specified speed when the motor is de-energized.  The plastic hub is subject to wear in use.  Stop members located on the weights and/or bracket prevent the pivot point of the arms from moving past the linkage over center line.

Abstract: Abstract of the Disclosure AIRCRAFT RUNWAY WITH GROOVED SURFACE     A manner of providing grooves in the surface of an aircraft runway is described.  The grooves are of skewed Y-shape in cross-section, having a steeply-sloping face and a gently-sloping face.  The grooves face in opposite directions at the two ends of the runway, each groove is orientated so that the gently-sloping face is toward the adjacent end of the runway.  A benefit of the arrangement is to combine a resistance to aqua-planing upon landing at high speeds on a wet runway, at one end of the runway, with a good friction grip between the and runway for emergency braking at the other end of the runway.  This benefit is present when the runway is used in either direction.
