Abstract: A line of longitudinal rows of passenger compartments are swingingly connected between upstanding pairs of hydraulically rotatable screws by means of internally threaded roll-nuts. The line can be raised or lowered with the compartments disposed mutually level and/or axially tilted, by joint rotation of the screws. Each row can also be axially rotated, all in programmed sequence. Seat-restrained passengers are thus exposed to varied and unexpected motion which challenges normal equilibrium feelings. Basic assembly can be permanently mounted on flatbed trailer for highway or rail movement to successive carnival locations upon disassembly of segmented screws and telescopic support towers which hold up the assembled screws.

Abstract: A portable starting block assembly for a track runner wherein the central alignment bar is formed in half-length segments for side-by-side lodgment during traveling, plus quick coupling means to fasten together the pieces during use. Also carries holding means for each anchorage pin against a block during non-use. The underface of the bar is formed with a lengthwise channel to receive an electric cable connecting an electronic reception unit at the rear with a front-end audio unit such as a start-signal microphone.

Abstract: A runner's starting block such as is attachable, one on each side of a longitudinal alignment frame, in staggered relation, so as to position each foot of a runner at a selected position for the start of a race. The block can have the tilt of its foot contact plate minutely adjusted to the liking of each particular runner, by interacting screw and nut elements terminally pivoted to move the rear of the foot contact plate, which setting is readable in degrees and accordingly reproducible on other similar blocks. Block also has extension plate adjustable to support heel or instep of runner's shoe as desired.

Abstract: A connector unit and a terminal box containing such units for individually coupling a plurality of closely grouped electrical cables to circuit breakers in the box in such manner that the cables can take off in a different direction without bending the cables. Unit consists of metal elbow with insertion lance at one end and cable coupling means at other end. May have second 90.degree. bend and also be shrink sheath insulated after installation.

Abstract: A rack for holding a quantity of record albums, each in a display position of at least partial visibility so as to be individually identifiable for selection by the user. An upstanding backing support which may be hung vertically against a wall or alternately back-tilted when floor supported, has vertically separated transverse ledges, each of which can support the lower edges of several upstanding albums (laterally overlapping). The backing support and its rows of upstanding albums is loosely overlaid lengthwise (vertically) by a restraining member such as a cord or chain which thus holds the total albums in place while allowing any individual album to be manually withdrawn and replaced laterally.

Abstract: A thermocouple assembly wherein the transition fitting has a separable nose piece which may be brazed to the probe casing before the transition fitting is coupled thereto, thus avoiding the previous occuring spread of brazing heat through the body of the fitting such as might damage contained wires and their soldered connections.

Abstract: A dental press or jig for rigidly positioning during a short curing period, a matching pair of dentures held in occlusal alignment with one or both having a contacting layer of relining material pressed against a respective model of the patient's mouth, all clamped together by the press within a body of plaster of Paris. The laterally-open press is formed of a pair of annular plates or disks, vertically spaced apart a constant distance by three, upstanding, peripheral posts which are thus tensioned against opposite faces of the composite workpiece. Each plate is formed with plaster escape-channels leading to catch basins on the outer faces, the basins being defined by a reinforcing pattern of diametric ribs within a peripheral rim which render the plates unbendable under pressure. The assembly may be molded of glass-reinforced terephthalate resin for high tensile and flex resistant properties.

Abstract: Cabinet useable for dispensing any tear-off length of a variety of rolled sheet material ranging from paper towels or toilet tissue to bandages or wrapping material. Following each selected withdrawal/severance from outlet mouth, sheet advance mechanism comprising gear driven contact roller is manually activated by reciprocation of thrust-inserted row of rack teeth so as to effect advance of fresh leading edge of sheet between it and supporting free roller. Latter includes fixed tangential fingers to insure non-clinging of sheet to free roller.

Abstract: Programmable electric and hydraulic machine for shaping laps such as are used to form or polish opthalmic lenses, comprises vertically oscillatable, longitudinally displaceable arm carrying a point cutter which is functionally engageable by radially extensible, rotating lap carried by upstanding spindle. Alternately, spindle is operable by oscillating drive when lap is radially retracted. Toroidal or spherical laps having a large range of variance in two dimensions, i.e. curvatures, are thus obtained by using relevant cutter and lap locations, as well as appropriate drive settings. Concave laps are produced by exchanging locations of lap and cutter so workpiece is carried by vertical-moving arm.

Abstract: Entirely mechanical assembly attachable to accelerator pedal of motor vehicle for selective setting of fuel flow. Chosen setting can be instantly overridden by pedal depression or be completely cancelled by tapping brake pedal. Set position is determined by longitudinal series of transverse slots on lengthwise-reciprocable control shaft, which slots are engagable by unidirectional latch; latter is disengaged by small rotation of shaft to bring smooth surface of shaft to sliding registration with latch. Cable connection between brake pedal and control shaft converts vertical movement of pedal to rotational movement of shaft.

Abstract: Provides a self-cleaning conic reaction chamber having specific multiple conduit connections, sealable closure, internal mixer, external vibrators and dependent sludge accumulator which chamber can be flow connected to readily available handling units to form a stepwise acid/iron/alkali assembly for treating contaminated liquid such as sewage or other waste water so as to obtain uncontaminated liquid and sterile sludge. Stepwise flow can be automated by adding stepping timer and electronic controller responsive to pH probes and pressure-, liquid level- and turbidity-sensors plus remote controlled valves, pumps, blowers and metering devices.

Abstract: Apparatus for step-wise purification treatment of contaminated polar liquid, such as water, by the procedure of U.S. Pat. No. 4,224,148, comprising successive flow-connected container units, electrically insulated from the ground, the sequential units providing: (a) macerating/distributing means for producing suspension of selected small-particle-size contaminant which will accept a galvanic charge, (b) means for maintaining acidic pH of 2 to 2.5 in presence of gaseous oxidizing agent, (c) source of soluble metal ions adapted to impart a galvanic charge on the small particles, plus subsequent aeration means, (d) means for introducing alkaline reagent while air blowing to restrain precipitation, (e) means for alkaline flocculation of separable particles, including pH control means and switch means for electrically grounding the liquid medium.

Abstract: A guitar having a split level top of its sound box which thus is formed at two different (vertically separated) levels and connected by an angular cross bridge to which one end of the strings is anchored so as to directly vibrate the chamber. The result is an increased sound volume and resonance persistance which is achieved without the distortion that may result from electronic amplification when applied to conventional guitars or other stringed musical instruments.

Abstract: Cylindrical open-top container houses generally annular slide track having diametric unidirectional stretch, the tracks being bordered by laterally extending guide rails which engage restricted necks of a row of individual holders which are each slidable along the track. Each holder supports a removable, outward-projecting hair tube, having a tensioning plug to yieldably retain a cluster of hair inserted therein. A pair of centrally pattern-apertured guide disks surround the outer edge of the track and are shiftable in unison 180.degree. in either direction so as to move successive holders from exit position of stretch to entry position at opposite end thereof, the shift being manually directed (by radially projecting lever) alternately clockwise and counterclockwise along the annular track so as thereby to braid together clusters of hair as they extend progressively from the respective trio of tubes thus carried by the slidable holders.
