Abstract: A device for encapsulating seeds in a gel. A nozzle with dual vertical, rectilinear, concentric tubes--i.e., an inner tube and an outer tube--is supplied with gel that is fed into the outer tube. The gel goes down the outer tube to an outlet from the inner tube, so that a meniscus of gel is stretched across the outlet. Singulated seeds are fed into an inlet of the inner tube, so that each seed--and only one--drops down upon a meniscus of gel. A slight puff of air is caused to pass down the inner tube and slightly inflate the meniscus upon which a seed has dropped. More gel is fed, to cause the meniscus to separate from the outlet and form a drop of gel with a seed inside, which drops down into a fixative bath that causes the gel to set.

Abstract: The device herein described is an automatic hydraulic transmission characterized by a minimum of servo-control apparatus.The provision hereof contemplates the extension of the torque multiplying range of a given hydrodynamic (or hydrostatic) unit by means of a fluid driven member thereof variably, differentially and continuously underdriving and overdriving the transmission's output shaft through a series of gear set-ups, in such manner that the speed ratio between fluid driven and driving members of said hydrodynamic unit is continuously varied along with the transmission's speed ratio throughout its operating range.

Abstract: An integrated-circuit one-way isolation-coupler for a controlling electrical circuit and a controlled electrical circuit and improvements in carrier-domain magnetometers and other applications thereof. In the isolator a magnetic-field source, such as a flat coil, produces a magnetic field from current applied from the controlling circuit, while a detector such as a carrier-domain-magnetometer detects the magnetic field so produced and produces a signal therefrom. A dielectric medium, such as silicon dioxide or silicon nitride separates the source from the detector. The source, the detector, and the dielectric medium, are all incorporated on a single IC chip, such as silicon, or gallium arsenide, or semi-conductor material. An amplifier may also be incorporated and may deliver the amplified signal to the controlled circuit. Preferably there are two carrier domain-magnetometers located so that they are symmetrical with respect to the flat coil.

Abstract: A constant voltage inductive power coupling for magnetically transferring electrical power from a power source through an air gap to a load comprising a first electromagnetic inductor connected to a power source to generate a shaped alternating magnetic field, a said inductor with a saturable core separated by an air gap from the first inductor and magnetically coupled thereto to receive the shaped magnetic field, the core being responsive to the field to enter a state of magnetic saturation. A coil is electromagnetically coupled to the saturable core and has output leads connected to the load. A capacitor is in electrical communication with the coil to form a tuned circuit that is below resonance at the coupling operating frequency. The magnetic field induced by the first inductor to the second inductor causes voltage in the coil, whose magnitude is determined by the amount of magnetic flux in the core.

Abstract: A body-protective article comprising matched portions of a rigid, non-shattering, high-impact resistant polymer, interiorly lined with an adherent high-impact absorbing elastomer. A protective body suit may comprise a series of interconnected segments providing a unitary suit, made up of such matched portions. The polymer is chosen from the group consisting of polyvinyl chloride, polyethylene, polypropylene, nylon, and polyester, and each of a sufficient molecular weight to make it rigid and non-shattering. The elastomer comprises flexible polyurethane of essentially linear structure containing unsatisfied hydroxyl groups, and having a compression set less than 15%, an elongation at break of at least 500% and a recovery which is delayed after compression by at least 0.7 sec. The matched portions have fixed adjacent interlocking edges that enable the user to enclose a body portion therein. Closures hold the matched portions together. Adjacent segments are usually connected together.

Abstract: An impeller shoe for a centrifugal rock crushing machine comprises an elongated body of wear resistant alloy material having a generally trapeziform shape with a back bearing surface on one side and a working front face extending longitudinally on its other side. The front face has a plurality of adjacent exterior surfaces, each surface forming a different acute angle with respect to the back bearing surface. The impeller shoe is adapted to be retained by a bracket on a horizontal turntable of the rock crushing machine to propel aggregate striking the front face to an anvil spaced outwardly from the turntable. The multiple exterior sections of the working front face in use produces a progressively wear pattern along its length that is substantial uniform in depth.

Abstract: A miniature diaphragm pressure transducer. A thin diaphragm of silicon nitride has an upper face covered by a zinc-oxide piezoelectric film encapsulated in chemical vapor deposited silicon dioxide. A series of annular, basically concentric, polysilicon electrodes are provided in the silicon dioxide between the piezoelectric film and the diaphragm and in contact with the piezoelectric film. A series of annular, basically concentric, aluminum electrodes are on the opposite side of the piezoelectric film from the polysilicon electrodes and are aligned with the polysilicon electrodes; they lie over the silicon dioxide, and are in contact with the piezoelectric film.

Abstract: A device for simultaneously performing multiple biochemical or immunological reactions. A manifold plate rests atop a waste fluid collection chamber or receptacle suitable for attachment to a vacuum pump. The manifold contains a series of wells that serve as reaction vessels. The sides of each well are fluid-impermeable, and its lower end provides a planar, annular base. A hydrophobic membrane is sealed to the lower surface of the base of each well. The membrane is formed of a material through which fluid can be drawn upon application of vacuum while retaining the fluid within the well in the absence of vacuum. By placement of a solid-phase support for binding biological coreactants atop the membrane prior to initiation of the reaction, solid-phase reaction products can be collected when vacuum is applied and can then be freely withdrawn from its well.

Abstract: A method for detecting the presence of antibody or antigen in a liquid sample suspected of containing the antibody or antigen. To a test panel comprising a nitrocellulose carrier having stably bonded thereto a microsized spot consisting of either a primary ligand for that antibody or an antibody for that antigen, is added sufficient liquid containing non-specific globulin for the material of the spot, to block adjacent binding sites. Then a small liquid drop of the sample suspected of containing the antibody or antigen is added. After incubation of the panel, in tests for detecting an antibody, a drop of liquid containing labeled antiglobulin, which is an anti-immunoglobulin for that antibody, is added. In tests for detecting an antigen, the specific antibody-enzyme conjugate is added. After further incubation wash solution is added to the spot, and the test panel is assayed for presence of the label.

Abstract: A safety device for mounting on a beam section including a body comprising two articulated portions having projections which produce a wedging effect on the beam section when under the pull of a load.

Abstract: A caliper brake for wide-tire mountain bicycles. Each caliper arm is pivotally mounted to a stationary pivot post of the bicycle frame via a cylindrical bushing to which the arm is press fitted. A return spring is retained around the pivot post in a normally stationary portion enabling purposeful adjustment. A brake shoe holder is mounted on one end of the caliper arm, and a roller-mounting post is secured to the other end. A cam roller is mounted rotatably on the roller mounting post by a low-friction bearing and has a circumferential groove engaging a cammed edge of a cam plate, to which a brake-actuating cable is secured. The brake shoe holder is preferably asymmetrical and is mounted for adjustment lengthwise of the caliper arm and for rotation around it and is also made adjustable as to the spacing from the caliper arm and as to the rotational position around an axis perpendicular to that arm.

Abstract: Continuous process for the manufacture of disposable diapers having an absorbent pad fixed inside a moisture-impermeable envelope. There are front and back transverse margins and a central crotch zone provided with lateral cut-outs to let the legs through. An elastic strand is fixed to the impermeable envelope by adhesion, at least in the crotch zone, and brought into contact with the inner face of the impermeable envelope while continuously driven by a smooth-surfaced rotary drum. The elastic strands are coated with adhesive throughout their length, and the tension exerted on them at the points of contact with the impermeable envelope is made to vary between a value approaching zero, corresponding to the portions of the elastic strands adhered onto the front and back transverse margins, and a maximum value corresponding to the portions of the elastic strands adhered onto the central crotch zone.

Abstract: A tire shredder. A housing has a vertical passage therein leading to a series of transversely disposed cutter wheels on adjacent parallel shafts. The shafts are rotated at different speeds, such as at 28 r.p.m. for one shaft and 34 r.p.m. for the other. The cutter wheels have flat side walls that partially overlap, so that rotation results in a scissors action reducing the rubber tires into manageable and disposable pieces. Preferably each cutter wheel has at least one tooth for engaging tires and pulling them into the shredder.
