Abstract: The propeller drive is installed with its drive shaft inside a boat hull and its driven (propeller) shaft outside. The shafts are interconnected by a timing chain. The drive shaft position is adjustable to adjust the distance between it and the driven shaft, thus adjusting tension in the chain. The drive shaft is carried in two bearings installed in two bearing carriers. The carriers are adjustably mounted on a drive shaft casing and are structurally interconnected. The adjustments are made by mechanical adjustment of the position of the interconnecting structure relative to the casing.
Abstract: A motorcycle front wheel suspension includes a pair of suspension struts mounted in parallel with a pair of fork struts. Each fork strut and suspension strut pair are connected at a bottom end by a link. The two fork struts are connected together by a pair of crossbeams. The top ends of the suspension struts are connected by arms to a crosshead. The crosshead is mounted to the top crossbeam through a pair of pneumatic springs. An axle is mounted to the lower ends of the suspension struts. A pressure air sources is installed on the motorcycle to provide pressure air to the pneumatic springs.
Abstract: The drive transfers power from an engine driven drive shaft to a propeller shaft, through the hull (not the stern) of a boat. The power is transferred by a chain and sprockets which are fully enclosed and lubricated by oil inside the drive. The tension in the chain is adjustable without disassembling the drive. The propeller shaft is carried on bearings in the main housing of the drive which is made up of a top plate, a streamlined hollow strut and the propeller shaft pod. The drive shaft is carried in a sub housing made up of top and bottom halves. The chain is installed before the top half of the sub housing and the bearings for the drive shaft are installed. This method allows for the slack and clearance (sidewise from the chain) for connecting the ends of the chain together. When the drive is fully assembled, the gap between the main and sub housing is mechanically adjustable to adjust chain tension. A sealing system seals the variable width gap to retain the oil in the drive.
Abstract: The primary structural parts of the handle are two telescopic tubes, the smaller diameter tube being an extrusion. A rib on the smaller tube engages a notch in a fitting attached to the larger tube to prevent relative rotation of the tube. A box footplate is attached to the free end of the larger tube with two degrees of angular freedom. The two axes of angular motion are perpendicular to each other and the axis of the handle. Angular motion of the box plate about one axis is transmitted by bevel gearing to telescopic torque transmission mechanism in the handle. Rotation of this mechanism and thereby the box plate about one axis is preventable by a lever operated clamp at the end of the handle. Rotation of the box plate about the other axis is manually adjustable. The length of the handle is manually adjustable and is set at a particular length by a lever operated length lock assembly.
Abstract: Two plastic film transparencies are rotatably attached side-by-side by engagement of film portions on one transparency with at least one incision on the other. There are images on each transparency and the rotatable attachment allows relative rotation of the transparencies to overlay the images on the transparencies. The images are cooperative so that overlaid images provide cooperative images. The rotatable attachment is accomplished by film portions on one transparency engaging an incision or incisions on the other. In some embodiments of the subject invention at least one of the transparencies is essentially circular. In all embodiments of the invention the relative rotation of the transparencies is in a range of 10° to 360°.
Abstract: The diaphragm assembly includes a diaphragm adhesively attached to a rim. The rim has a C-shaped cross section with the C-shape facing inward and a membrane extending radially inward from one of the radial portions of the C-shaped portion. The diaphragm is attached to the membrane. The thickness of the membrane is about two tenths of the thickness of the section of the C-shaped portion. The groove formed by the C-shape engages a rib on a stethoscope chest piece to install the diaphragm assembly.
Abstract: The primary structural parts of the handle are two telescopic tubes, the smaller diameter tube being an extrusion. A rib on the smaller tube engages a notch in a fitting attached to the larger tube to prevent relative rotation of the tubes. A box footplate is pivotally attached to the free end of the larger tube, the axis of the pivot being perpendicular to the axis of the tubes. The footplate is connected by a connecting link to the end of a tube which slides longitudinally in the handle and fits through a clamp mechanism installed in the overlapped end of the smaller tube and is operated by a clamp mechanism operating assembly attached to the free end of the smaller tube. Operating a lever of that assembly engages the tube in the lock mechanism, preventing it from moving longitudinally and the footplate from pivoting on the handle. The length of the handle is manually adjustable and is set at a desired length by a lever operated lock assembly attached to the overlapped end of the larger tube.
Abstract: The cap snaps onto the neck of a container used on a water dispenser and has an inner cylinder, which engages a probe in the dispenser when the container is installed on a dispenser. The end of the inner cylinder is closed by a membrane which is frangible and grooved such that the probe breaks the membrane into a plurality of petals which are displaced and deformed as the probe moves through the cap. The membrane extends into the inner cylinder and is turned inside out as the probe passes through. In a preferred embodiment the membrane has an outer rim, a first frusto-conical portion, a second rim, a second, smaller frusto-conical portion extending in a direction opposite the direction of the first frusto-conical portion and a flat end.
Abstract: The tube assembly is made up of an outer, elastomeric tube, a close wound metal spring inside the outer tube and a layer of material inside the spring to provide a smooth inner surface for the assembly. The layer may be a thin-walled elastomeric plastic tube or a layer of elastomeric material applied to the inside of the spring. Also, the spring wire may be coated with elastomeric plastic.
Abstract: The subject basic method and its modifications are used to provide logs reconstituted from smaller diameter trees up to 12 inches diameter at their bases. The basic method is practiced using the following steps:
1. Cutting felled trees at cutting points into a plurality of segments which, naturally, are tapered, each segment having a length, a larger diameter end and a smaller diameter end, the length being in a range of random lengths such that the larger end diameter is in a range of 0.2 to 2.0 inches larger than the smaller end diameter, with 0.2 inch preferred;
2. selecting from the plurality of segments cut from one or more trees, a plurality of groups of segments which have smaller end diameters no more than ½ inch different;
3. joining segments from each group end-to-end to form reconstituted logs of optimum lengths for processing into wooden structural units.
In one modification of the basic method, flawed portions are removed from the logs prior to cutting them into segments.
Abstract: The mixer has a circular forward end which is attached to the exit of a jet engine, or the core of a bypass engine. The mixer has radial lobes which increase in their radial dimension with increasing distance aft of the forward end. There are corrugations, termed circumferential lobes, in the after portions of the walls of the radial lobes. These circumferential lobes increase the ratios of wetted areas to cross sectional areas of the passageways through the mixer. Also, the dimensions of these lobes are small relative to the radius of the mixer.
Abstract: A first plastic film transparency (10) is formed to include an image (14). A second plastic film transparency (12) is formed to include a complementary image (16). The transparencies (10, 12) are positioned side-by-side. The first transparency (10) is formed to include a circle of circumferentially spaced apart incisions (18) in it. The second transparency (12) includes film portions (20) that project through the incisions (18) and connect the transparencies (10, 12) together for at least some rotation, one relative to the other. One transparency (10, 12) can be rotated relative to the other to bring the images (14, 16) into a predetermined relationship, each to the other, so that the two images (14, 16) when viewed together will provide a predetermined combined image.
Abstract: The primary structural parts of the handle are two extruded telescopic tubes. A longitudinal rib on the smaller, inner tube slides in a groove in the rib on the larger, outer tube, preventing relative motion between the tubes. A box footplate is pivotally attached on a shaft to the free end of the outer tube with the axis of the shaft intersecting the long axis of the tubes and perpendicular to it. Rotation of the footplate is transferred by bevel gearing to a rod at the centers of the tubes which extends through a collet mechanism installed inside the smaller tube near its overlapped end. A lever and related linkage are attached to a fitting installed at the free end of the inner tube. The linkage connects the lever to the collect mechanism. Operation of the lever causes the collet to clamp onto the rod, thus locking the box footplate angular motion and the length of the handle. An auxiliary mechanism may be provided for locking the handle at any of a series of lengths.
Abstract: The load supporting and moving surface of the conveyor is made up of longitudinal members called slats. The slats are edge to edge with small gaps between the edges. The slats are supported on longitudinal bearing strips, one edge of each slat on one strip, the other on an adjacent strip. The bearing strips are supported on longitudinal beams, evenly spaced and running lengthwise of the cargo space of the conveyance in which the conveyor is mounted. The longitudinal beams are supported by and fastened individually to crossbeams of the conveyance. The bearing strips slide longitudinally onto the longitudinal beams and the slats slide longitudinally onto the bearing strips. Clearance is provided for fastening the longitudinal beams from above. The upper surfaces of the bearing strips have longitudinal grooves in the center of their upper surfaces. Flanged ribs on their lower surfaces engage the flanges of the longitudinal beams to hold the strips in place. The edges of the slats are over the grooves.
