Abstract: The water in a closed loop geothermal system is caused to flush the system by reverse flow of water in and through the system. This provides a "well-to-well" full reversal of the water flow, thus permitting the factor of a primary receiver well to not only receive the geothermally used water from the primary well, but for that receiver well to then serve as an aquifer subsequently for causing the flow to go back to the primary well.

Abstract: Tubular frame pieces, with generally a welded construction, provide a sturdy support for mounting a heavy duty vise or other heavy-duty tool. Convenient changeability is provided from an erect working condition to a compact condition for transport or storage, even though such convenient changeability would not be expected for such heavy duty apparatus. A rear leg frame assembly and a front leg frame assembly are rotatably carried by transverse bars of a base frame. Temporary or partially-supported condition is provided for ease of erection, but a positive erection-holding feature is also provided. Extender bars are optionally provided for carrying ancillary features in addition to the mounting table for the vise. A base frame is provided with wheels, the wheels being movable to a floor-engaging position for ease of mobility, and a retracted position for maximum sturdiness.

Abstract: A hard case coin display holder advantageously universal to coin size and shape, especially useful for ancient coins and Spanish pieces-of-eight which are always of irregular size and shape, while holding the coin attractively spatially centered, by at least two flexible transparent spring tension arms, within the protective confines of a quickly and easily assemblable and disassemblable see-through hard case. The present invention leaves much more of the irregularly shaped coin visible in the display than that achieved by opaque resilient rubberlike holed cores, which are the only present universal coin display interiors.

Abstract: Apparatus and procedure for sorting mail and the like rapidly and accurately. An array of sorting modules each contain a shelf or base and a series of vertical separator panels which divide the shelf area into a plurality of bins into which individual mail items may be selectively placed. A frontal connection feature extends transversely of the shelf, holding all of the grid of panels for movability as a set upwardly away from the shelf, but also individually movable transversely to give a bin-size adjustment to individual bins automatically in accordance with respective bins' needs. The frontal connection provides for the upward rotation with respect to the shelf, from a fore-and-aft panel-position which provides the sorting bins to move to an upraised position in which the panels are freed from the sorted mail batches so that the full set of sorted mail batches may be bundled as a group of code sets.

Abstract: An outlet protector auxiliary, for a vent duct which leads exhaust substance from equipment, such as lint and moisture from a clothes dryer, for venting discharge exteriorly of a building's wall, the vent duct outlet having a movable closure flap which has a substance-discharge position and a closed position. The auxiliary is in the form of a metal framework providing a cage-like body member, having enclosure panels having openings of a restricted size such as to permit discharge of exhaust through the openings but to block entry into the duct, from the wall's exterior, of matter of any size significantly larger than the particles of exhaust substance for which the auxiliary is provided; and the cage-like body member has a peripheral flange by which it is connected to the wall.

Abstract: A foot-rest device for a motorcycle, the foot-rest having a telescopable assembly of at least two and preferably three cylindrical support bodies, whose telescoping nature provides that they may be easily adjusted to either an extended foot-rest position or to a retracted position. Screw-type and spring components releasably hold each of those conditions, providing a safe foot-rest position for the cycle's passenger, but also a retracted position not attainable by swivel-type connectors.

Abstract: A head cap having an opening on its upper central or crown portion of the cap body, the opening being for receiving a "ponytail" hair style, with the walls around the opening providing lateral support to the ponytail. A neat and trim appearance of the ponytail extending through the opening is achieved, and the attractive vertical support is given to the ponytail even though given only by lateral support. In another embodiment, at least two openings are provided, spaced laterally of the median line of the cap body, accommodating a dual ponytail style.

Abstract: A probe apparatus especially useful in probing circuit boards used in electronic equipment. Two beam support members of unequal length and in a spaced relationship to a work object having the longer beam between the shorter beam and the work-object, the two beams being attached to a moveable support at joints substantially displaced in the direction of the beams' lengths, the other end of the two beams being attached to the probe support members at joints that follow the arcs of rotation required to cause the probe tip to pass through three points of a straight line travel of the probe tip during z-axis flexing, thus maintaining the position of the probe tip in the x-y plane during z-axis flexing. The resulting motion is a rotation of the end opposite the probe tip, in the x-z plane, pivoting at the initial contact point of the probe tip, thus avoiding an x-y plane "wiping" of the probe over the contact area which may damage the work object being probed.

Abstract: A golf ball having internal parts which provide sound-emission upon the ball being struck, the sound continuing until the ball is found and the golfer releases the actuation switch, that action also cocking the device for the next golf shot which re-starts the sound-emission.The sound-emission parts are all carried internally by the ball body; and they include an electric sound-emitter, a movable carrier member, a metallic inner cap for the carrier member, and a metallic actuator member. A spring both biases them into sound-emission contact and also serves as a conductor in the sound-emitter circuit. Frictional and releasable holding means provide for establishing and maintaining a sound-silent condition, against the bias of the spring.An actuator tool is provided, having both an actuator shaft and a torque lug, for convenience of manual actuation of the device details.

Abstract: A bracket body which is easily affixed to the brake rod and clevis member of conventional brake adjustment apparatus of air-actuated braking mechanism, provides indirect measurement of brake rod travel and adjustment, by the body showing the amount of angular rotation of the brake's adjuster member, even though brake rod travel is a generally linear stroke movement. The bracket body has a central body portion from which extends two extension members, a first one of the extension members being provided with attachment for the clevis and brake rod assembly, and the central body portion with attachment to the clevis pin. The second extension member provides the visual reference by relevance to the adjuster member.

Abstract: A locking screw feature provides lockable adjustability for the slab-supporting ledge member which supports the heavy slabs used to form the face-wall of mausoleum crypts. The lockability permits the ledge member to be made to be freely slidable in its receiver slot of the hanger body which is connected to the structural concrete of the building; and the ledge-lockability is achieved by a locking screw which passes inwardly through the ledge member, and is forced against the hanger member, thus permitting the fit of the ledge member to the hanger member to be freely slidable. This combination of features not only accommodates the adjustability to be easy and precisely accurate, but also tightly locks the adjusted position. Preferably, the ledge member passage for the locking screw is provided as a inward extension of the ledge member hole which holds the screw which holds the rosette cap which conceals the junction of the slabs.

Abstract: A double basket providing separate containers for a primary substance (e.g., French fries) and an associated condiment substance (e.g., catsup in a cup). The secondary basket has a small auxiliary wall supported by the principle basket's wall panel for juxtaposition along the primary basket's wall panel, but movable to a basket-open position away from that closed position. The auxiliary wall and its support arms provide, nevertheless, that in the closed-pocket condition the pocket components pose significantly no deterrence to what is provided to be a "nestable" stackable feature of a plurality of baskets.

Abstract: A locking apparatus, particularly desirable for modifying a "push/pull" latch apparatus for a hospital door, by which it may be released from a locked condition by manual effort applied from either side of the door, thus giving an unlocking effect to a door even though its locking has been caused by a manual locking effort applied by the person on the other side of the door.The apparatus has a particularly beneficial use in a large commercial installation such as a hospital, and provides that the lock-releasability may be achieved by a manual effort applied wholly on the outside of the door, as well as the person on the inside of the door being able to either lock or unlock the door; and, although the door may be locked or unlocked from either side, the unlocking component manually operable to lock or unlock the door from the outside is provided to be of such an inconspicuous nature that it would be realistically considered to not be a component with a door-unlocking effect.

Abstract: An improvement in reduction of particle size of painting and coating particles is achieved by providing a tapered channel(s) in the cylindrical wall radially of the spray apparatus' nozzle head, which is a wall adjacent the nozzle outlet slit. Using the "Bernoulli Principle," its venturi feature achieves a movement and acceleration of ambient air to intermix with the paint particles being dispensed through the nozzle outlet slit. The tapered channel(s) extends radially inwardly from an air inlet opening on the exterior face of the wall, fully through the wall, and into a downstream air outlet opening on the interior of the wall face, the tapering of the channel being of a downstream size-reducing nature.

Abstract: A thrill-ride apparatus having as a basic concept the revolving of a rider station, whose support provides that the path of the ride will be along an inclined plane. The rider station is fixed to a support arm; and there is no counterbalance as to the weight of the support arm, rider's station, and the rider. The path of the rider is thus such that he must incrementally achieve not only the revolution with respect to the ground and the axis of the support structure, but by such oscillating incremental efforts achieve a raise from "bottom dead center" to "top dead center" as supported by the base of the apparatus.

Abstract: A basketball shooting training device, of both direct and an indirect training aid nature and benefit; i.e., it is direct in the sense that practice with it is practice for accuracy while being forced to shoot with a recommended shooting technique, and indirect in the sense that practice with it helps, and in effect practically forces, the development of that recommended shooting technique itself, thereby assuring the avoidance or breaking of a tendency or habit of using undesirable force from a one-hand shooter's other hand or from of that other hand's thumb, and thus assuring better and more consistent one-hand shooting.The device is a sort of harness-like apparatus, having a special control member which provides a rather rigid even though yieldable restriction to the user's "other" or guide hand or its guide thumb and to its or their use during the shot. The control member is a tension member, yieldable in form, and of a moderately stiff yield character of about 1.

Abstract: A gauge for indicating the setting and linear stroke movement of a brake rod of a brake assembly. Reference indicators are provided on both the brake-rod's yoke or clevis and on the arm of the brake's slack adjuster member; and the indicators cooperate, by their relative movement, showing brake rod travel and adjustment as a visual indication by the relative movement by the reference indicator of the linearly-moving clevis with respect to the angular rotation of the reference indicator on the rotating-slack adjuster arm.
