Abstract: A flexible coupling for flexibly joining two shafts includes a unitary solid cylindrical body having a first end, a second end, and therebetween having one or more longitudinally spaced circular disks spaced by asymmetric slot pairs; a radially offset beam formed between a first slot and a second slot of each asymmetric slot pair, such that the radially offset beam is parallel to a diameter of the cylindrical body and is offset from the parallel diameter by a radial beam offset distance R1; each beam being rotationally offset from longitudinally adjacent beams; and hub means at the first end for coaxially connecting the first end to a first one of the two shafts, and hub means at the second end for coaxially connecting the second end to a second one of the two shafts.

Abstract: A shaker apparatus having a platform for carrying a load, a supporting base disposed beneath said platform, drive means carried by the base and operatively connected with the platform to provide horizontal shaking of the platform in an orbital motion with respect to the base, eccentric idler devices connecting the base to the platform for maintaining the platform in a substantially planar orbit substantially parallel to the base during the horizontal shaking of the platform and to eliminate backlash, and alignment elements associated with the eccentric idler devices to prevent the transmission of rigid, non-yielding force loadings between the platform and the base through one of the eccentric idler devices when the force loadings are generated at another of the eccentric idler devices or by the drive means. A second embodiment includes alignment and support structure to prevent transmission of rigid, non-yielding force loadings and to support the platform.

Abstract: Construction and method of making a decorative cracked glass laminate in tile, panel, sheet, plate, veneer or in situ form. It comprises three layers laminated together, an inner backing layer, a substantially light-transparent outer layer, and a decoratively cracked glass intermediate layer sandwiched between the inner and outer layers. The intermediate layer, preferably a mirror, is made of tempered glass and the outer layer is made of annealed glass. The laminate is made by laminating the inner and outer layers to the intermediate layer while it is in uncracked condition, and then causing it to crack in situ as by cutting into an exposed edge. Alternatively, the two glass layers may be laminated together and then laid in a backing material such as plastics which then forms the backing layer of the two-glass laminate.

Abstract: A word game playing piece having at least one gravity-stable playing position, at least one gravity-unstable playing position, and a holder that supports the playing piece in its gravity-unstable position. The playing piece is provided with word game indicia, concealed when the playing piece is in its gravity-stable playing position, and revealed when the playing piece is supported in its gravity-unstable playing position by the holder. The player piece is automatically self-righting from gravity-unstable to gravity-stable position to minimize the exposure of its indicia to view.

Abstract: A glass microscope slide made of low annealing temperature glass and having an opaque, porous, ceramic marking surface permanently fused thereto, and a method for making same. The ceramic marking surface may be formed on one side or on both sides of the glass microscope slide and at either end on either side. Different ceramic colors may be used for color coding the slide.

Abstract: A motorcycle bumper system having at least two non-confining bumpers, one on each side of a motorcycle, the bumpers being located adjacent the normal riding position of the rider's legs, and being matched to the vertical dimension and height from the ground of conventional automobile bumpers to provide primary protection against a sideward impact in an automobile-motorcycle collision, the motorcycle bumpers being secured to the motorcycle frame by straight-line bumper supports oriented to point substantially squarely at the colliding automobile bumper and enabling the motorcycle bumpers to meet the impact of the automobile bumper head-on, further protection being provided by a cam-faced rigid bumper configuration adapted to cam the colliding automobile and motorcycle bumpers apart, and an energy-absorbing covering on said bumper.

Abstract: The purpose of this patent is to permit the use of diesel fuel for spark-ignition engines, whatever the type, e.g. two- or four-stroke piston engines (Rochas-Otto cycle); rotary (all types, including Wankel) by spraying diesel fuel onto a hot exhaust manifold to vaporize the fuel within an intake manifold.

Abstract: A construction of an element adapted to provide fire-resistant support for a relatively fragile and relatively heavy decorative glass member, the construction converting that element into a structural element having in bonded combination a water-felted mineral fiberboard panel, a glass mirror, and a latex-, rubber-base or epoxy waterproof adhesive, the combination being edge-supported on a hung gridwork.

Abstract: Retaining means and method for use with multi-leaf spring clamps used to secure culture flasks, bottles or the like during imposed orbital, reciprocating or vibratory motion, a resilient encircling member which has adjustable engagement with the leaves of the spring clamp to prevent relative movement between the flask and the clamp. The resilient encircling member is provided with internal annular ribs or threads to engage the spring clamp leaves and may have a deformation-resistant annular flange for insertion and removal of the encircling member and for control of engagement pressure and holding power.

Abstract: A dual expansion and non-expansion anchor comprising a pair of inner and outer expansion fasteners connected to each other by means of a screw-threaded connecting tie, said expansion fasteners being adjustable on the connecting tie to adjust to the spaced positions of an inner supporting structure and an outer supported wall. Insertion limiting means is provided to limit insertion of the inner fastener into the inner supporting structure in order to fix the position of said inner fastener in said supporting structure. Torque applying means applied to the connecting tie inserts and sets the inner fastener. Torque applying means applied to a nut on the connecting tie expands the outer expansion fastener.

Abstract: Apparatus and method for drying fresh printed web material such as vinyl by reduction in ambient air pressure surrounding the web by forming the web into an air foil and passing warm dry air thereover.

Abstract: For use primarily in high-speed collating of multiple sheet inserts for mailing pieces, a series of rotary feed station means each having a plurality of gripping means are located above collating insert conveyor means. Each feed station feeds an insert, usually a single folded sheet, onto the conveyor at timed intervals such that the second feed deposits its insert onto the first insert, the third is deposited onto the first and second, etc., until all desired sheets are collected for inserting into an envelope.
