Abstract: For vial samples of milk collected along a route of dairy farms, a sample vials tray is provided of foldable mode that can be readily accommodated within the limited-volume ice chest of the route agent's truck. At the agent's milk processing plant, the same tray, and with the sample vials undisturbed therein, can be employed in the non-folded and latched condition required for automated laboratory analysis of milk samples contained in the tray-housed vials. A multi-prongs type holder holds each vial in a secure condition during the vehicular journey from dairy farm to milk processing plant. The foldable tray utilizes a special hinge that is relegated to a non-obtrusive location that does not interfere with the tray's usage in concert with automated laboratory analytical equipment.

Abstract: Leverage lifting cart, utilizeable along two distinct and generally horizontal planes, has a longitudinal cargo receiving bed attached to a pair of laterally extending and preferably wheeled axles including a fixed-elevational rear-axle and a front-axle carried by a vertically controllably movable carriage extending pivotably and medially downwardly from the cargo bed. The vertical distance between the carriage supported front-axle and the cargo bed is remotely controllable by an operator nearby the cargo bed front-end. Specially contoured bridges connect the rear-axle to the front-axle. By virtue of this basic structure, and which can be desireably augmented with other novel structural features, the operator can leverage cargo loads between disparate planes and can safely, reliably, and conveniently maneuver the loaded cargo along the available expanse of one or more planes.

Abstract: Power-transmission sheaves conventionally include a centrally-open and shaft-engageable hub portion surrounding a directionally transversely extending hub-axis and together with at least one grooved belt-training portion that is surroundably connected to the hub portion and that provides a grooved outward periphery for the sheave. The at least one belt-training portion includes transversely separated flanged sides for the belt-training groove. Such conventional power-transmission sheaves are given enhanced belt engagement by providing one, or preferably both, of the flanged sides with a plurality of transversely extending openings therethrough.

Abstract: For cantilever mounting to and slidable positioning along upright channel members, there is disclosed retailing display brackets including a conventional display or hanger bar that is connected to a novel anchor-member. The anchor-member has triangular wings including a rearward prong and also leaf-spring which together normally bear against the channel rear-face and effect a cantilever mounting for the elongate bar. With such prongs and leaf-spring combination, specially contoured or perforate channel rear-faces are unnecessary. For slideable height adjustment of the anchor-member along the upright channel, the operator briefly maintains the elongate bar in an inclined condition which de-activates the wing prong and the leaf-spring during the height adjustment process.

Abstract: For use in combination along the transversely extending horizontal rear-end of a pickup truck or other overland vehicle, there is described an upright end-gate that is also alternatively employable as a ramp or as a trailer whenever panels of the end-gate are freed from their upright gating condition.

Abstract: The retailing display assembly is of the upright channel and slidably positionable and releasably anchorable type. The upright channel has an upright rear-wall provided with two columnar arrays of rearwardly struck lanced openings therethrough. The bracket includes a conventional horizontal hanger bar extending rigidly forwardly from an upright web member. The web member is provided with a pair of forwardly extending wings abuttable against the channel member front-walls and is further provided with a pair of downwardly and rearwardly extending tabs that are releasably anchorably protrudable through selectable co-elevational openings of the channel rear-wall.

Abstract: For use with an overland motor vehicle including therewithin a traversal-recording odometer that is actuatably connectable to the vehicular transmission, there is disclosed an odometer disabling system for disabling the odometer during time periods when the motor vehicle is being towed and during which it is inappropriate to record overland traversal of the towed vehicle.There is a novel electrically-disengageable spring-actuated clutch intervening between the vehicular odometer and transmission and co-acting with and along the flexible-shaft connection between the odometer and transmission. The clutch has the capability of maintaining the traversal-recording integrity of the odometer only so long as electrical current is not being fed into the electrically powerable coil of the clutch.

Abstract: Steering sulkies of the present invention are based upon the "crank/steering-rod" mechanical principle but provide profound refinements thereover. Cranking is provided at first and at second stations. At the first cranking station, preferably overlapping left-link and right-link effect simultaneous rotation of the two sulky wheels about their transversely separated vertical axes in response to towing vehicle steering; such first crank is contingently abuttable against blocking stops to prevent sulky jackknifing. The second crank, which is co-rotatable with the first crank, is connected to the rearward end of elongate steering-rod that herein intersects the frame longitudinal-axis before being terminally connected to a frontal hitch. A preferred hitch provides a convenient, reliable, and multi-directional flexural connection between a lawn-mower or other towing vehicle and the trailing self-steering sulky.

Abstract: Conventional retailing display brackets having a single-offset-anchor portion are self-secureable to internally horizontally slotted upright panels. To adapt such brackets for similar self-secureable engagement to latticed panels, the present invention provides a height-extender adapter clip that is securely slideably mountable to the bracket's single-offset-anchor portion. The height-extender adapter is fabricated by strategically joining a laminar front-plate to a hooked rear-plate, and which plates are specially contoured for slideably bearing against selected areas of the bracket's single-offset-anchor portion.

Abstract: A limb supporting device for reclining persons has a tri-segments pillow having a volumetrically predominate and apexial central-segment flanked by hingedly associated lower secondary-segments for uprightly stabilizing the limb supporting device upon a bed-like reclining surface. An elongate girth strap gives selectable contour and resiliency to the pillow central-segment according to the limb cradling needs of specific reclining persons.

Abstract: Rotary toothbrush utilizes a longitudinally extending hollow barrel having a fore-end and a rear-end. Longitudinally extending and reciprocatable strokearm mechanism is predominately located within the hollow barrel but includes a forward-portion always located forwardly of the barrel. A pair of transversely separated, upright rotary brushes are positioned wholly forwardly of the barrel and there eccentrically journal crankshafts carried by the strokearm mechanism forward-portion so that strokearm reciprocations cause the two brushes to move together in alternating angular directions. The strokearm mechanism forward-portion might be provided with auxiliary bristles for simultaneously brushing the dental occlusial surfaces as the rotary brushes treat the bucal and lingual surfaces.

Abstract: Prop-like positioning devices for hemiside reclining persons and including: a bolster or other lofty pillowy structure extending along a longitudinal-axis and being in longitudinally extending attached relationship to a flexible apron member extending lengthwise along a lateral-axis. The apron member is superimposable upon a bed-like reclining surface directly beneath a longitudinally extending body torso. Plural pockets exist on both lateral sides of the pillowy structure and for receiving selectable therapeutic devices for the reclining person, and preferably a pair of vertically open pockets on both lateral sides. Other permissible optional features render the positioning device usable by reclining persons not having constant nursing or attendant care.

Abstract: Robbery alarm switch having two independently manually engageable plungers that must be substantially simultaneously moved by a cashiering accostee to actuate a summoning alarm. The robbery alarm switch includes at least one internally housed reedswitch connected in electrically intervening relationship to the summoning alarm. The two independently manually engageable plungers are respectively provideable with an addendum source of magnetic flux (e.g. a permanent magnet) so that, when the two plungers are together independently moved teamwise from normal first-station to second-station, the two magnetic flux sources act in concert to change the distance between the reeds of every electrically intervening reedswitch and thereby actuate the summoning alarm. Included among various optional features are: a supervisorily releasable housed latch extending between the two plungers; attaching the housed reedswitch to one of the two teamwise plungers; etc.

Abstract: Readily erectable, operationally reliable, and nestably transportable ice fishing tip-up apparatus includes three structurally interchangeable and uniquely apertured channel members alternatively designatable as alpha-member, beta-member, and gamma-member. The alpha-member and beta-member are adjustably pivotably joined in parallel horizontal planes, and the gamma-member is pivotably joined in an angularly inclinable relationship to the beta-member. An omega-shaped prop member, which is pivotably attached to the beta-member, can engage an underlying stop member of the inclined gamma-member. A fishing line reel is attached in flanking relationship to the gamma-member with an axle that can also function as the stop member. An elongate lever, which medially surrounds a fulcrum terminus of the gamma-member, includes a relatively shorter and slidably weighted leadward-arm that abruptly falls whenever a fish is caught at the fishing line.

Abstract: A monolithic block, preferably singularly constructed of moderately resiliently compressible and flexible resinous material, has a generally horizontal base surface, two angular ends including a left-wedge of about 30.degree. to 40.degree. and a right-wedge of about 10.degree. to 20.degree., and an upper-medial surface terminating at fulcrums alternatively abuttable against an automobile door pane. Selectable employment of an angular end will wedge sufficient space between the transparent fragile pane and the opaque casing of an automobile door to permit insertion of some conventional locksmith's probing tool for unlocking the automobile door, and without appreciable danger of cracking or damaging the fragile door pane.

Abstract: Apparatus and method utilize an open-top hopper having an upper cascade-zone and a lower pool-zone. Crude snow-debris is intermittently dumped into the hopper open-top and there operationally admixed with low-temperature water; this admixture is converted by cascade-zone comminution drums into a rough-slurry that pools at the pool-zone. Within the pool-zone, the rough-slurry is agitated, preferably with a revolvable bladed shaft, into a smoothly flowable-slurry that is dischargeable through an apparatus outlet to a remote disposal site which might be a municipal sewerline. Preferably, the apparatus takes the form of a wheeled vehicle, has a lengthily agitated pool-zone extending beyond the hopper, and is equippable with other desireable optional structural features.
