Abstract: Speed bumps for mounting across roadway lanes to encourage vehicle drivers to slow down are formed of laminated layers of elongated flexible rubber strips secured together to form a speed bump unit. Typical bump heights of three inches are obtained from six laminated half-inch layers. in one embodiment, layers not exceeding five inch widths cut from treads of discarded vehicle tires between opposing shoulders have a propensity to lie flatly upon a road surface, and are pyramided upwardly by a plurality of stepped layers of decreasing widths thus presenting inclined leading and trailing edges for intercepting the tires of oncoming moving vehicles. In another embodiment curved layers of tire tread strips form ingress and egress edges inclined gradually downward from an uppermost crown to the roadway surface for intercepting the oncoming moving vehicle tires.
Abstract: A flexible impact energy absorption resilient and flexible rubber strip accessory has an adhesive layer for affixing it to an exterior curved automobile body surface. An inexpensive preferred embodiment is formed using tire tread strips cut from the carcasses of discarded automobile tires. Thus, steel belted tires provide embedded reinforcement for absorbing higher levels of impact energy without any visible damage to the tread strip or the adjacent car body surface upon which it is affixed. This accessory has an adhesive layer for attachment to a car surface having a manually protective paper or plastic cover so that it may be retrofit upon an exterior surface of an automobile without requiring any special tools. The accessory is universally adaptable to a large range of automobile body styles.
Abstract: This invention provides integrated knuckle drive link conveyor belt systems with improved long wear-high load bearing link coupling joints of a universal joint nature for permitting the belts to travel on straight or curvaceous paths which also feature expedited insertion of spindle rods extending through the knuckles, diverse sprocket drive capabilities and replaceable load conveying platform accessories of the plug-in or snap-in variety. A cylindrical knuckle, when the loaded belt is under tension, has a substantially semi-cylindrical high wear contact surface that handles heavy peak loads. That knuckle is installed expeditiously at a joint between end-to-end connected links constituting a special interfitted jig comprising a seat in the nose end of a link resting the knuckle in a registered operational position to receive the connecting spindle rod through trailing edge bifurcated arms of a leading modular link without a concurrent manual orientation of the knuckle.

Abstract: A chain link conveyor belt carries lateral slats extending from the chain links, upon which are formed integral ribbed finger load carrying platform structure that interdigitates and overlaps their ribbed fingers with leading and trailing chain links in a conveyor belt. Wider belts are feasible when a parallel pair of spaced chains support the lateral slats extending horizontally from the chain links to the belt edges. The chain links are Y-shaped with elongated pivot rod slots in the leg to permit flexibility for laterally pivoting the belt around curved paths. Specially shaped structure on the slats near the belt edges supports long finger tip ribs of adjacent slats, thereby to strengthen the edge portions of the belt. The outermost fingers are reinforced to slide on guide rails. The trailing ribbed fingers diverge inwardly from the belt edges to avoid interference and fracture.
Abstract: An accessory is provided for mounting flags, typically favorite team pennants or insignia, on the rooftops of vehicles provided upwardly extending bars such as luggage racks by means of a clamping mechanism that orients a flagstaff vertically a predetermined distance above the rooftop, and thus provide high visibility without interfering with driver vision or damaging the exterior surface of the automobile. The flag vertically extends at a height that serves as a car finding signal in crowded stadium parking lots.
Abstract: A roll-up screen door appliance for drawing a screen panel horizontally across the span of a door frame, which advantageously may be stably positioned in a partly open position for permitting persons to pass through with a minimum opening, thereby reducing the opening size for entry of insects. The screen panel is rolled up on a spring-biassed, vertically-oriented supply roller and is withdrawn by a manually moved pull rod clamped to the distal end of the screen panel. The pull rod is frictionally held in a stable position across the span of the accompanying door frame as it is withdrawn and the friction is overcome manually as the screen is retracted upon the storage roller by a spring biassed mechanism.
Abstract: This invention provides a device which facilitates electrical wiring and equipment costs for electricians installing disconnect boxes, typically in the vicinity of an outside air conditioner unit. Thus, an improved disconnect box for protection of an electrician who is servicing an electrical appliance such as an outside air conditioner is provided which incorporates an integrally mounted auxiliary electric socket accessory giving the electrician a source of power for use while the electrician is safely assured that there is no power connected to the electrical appliance being serviced. The auxiliary electrical socket accessory may optionally be connected to a power line source as a full time electric plug outlet or one only accessible when the disconnect box is conditioned to disconnect power from the electrical appliance. Provisions are made for protection of the electrical socket accessory with fusing or circuit breaker protection and ground fault protected electrical input wiring to the electrical socket.
Abstract: A modularized electric box system provides a minimum of modular elements, typically two or three from which a basic anchor box may be formed with protruding members for support by a building body, and from which gangable extensions thereto may be fashioned. The modules may constitute a basic open front electrical box frame having at least one open side with interlocking structure for receiving and supporting either a sidewall panel or a gangable U-shaped extension box module. An anchoring box may be formed with anchoring structure integrally protruding from end panels thereof adapted for attachment to a building body. Thus minimally a basic U-shaped box frame module without sidewalls interlockable with a similar module and a removable sidewall module interlockable upon a U-shaped box frame at the open sidewalls will form a gangable box system. Interlocking channelwork permits unimpeded insertion and removal of modules by sliding movement perpendicular to the open box fronts.
Abstract: This invention solves the problem of removing undamaged inflated dunnage bags from a cargo space by using a high pressure air source to both open the dunnage bag inflation valve and to suck air out of the bag by discharging the high pressure air through a venturi system. Thus large dunnage bags may be deflated in about one minute. The deflation valves provided by this invention also serve as inflation valves by simply disabling the venturi system.
Abstract: A multipurpose two piece soap dispenser is provided with an ornamental water impervious hollow reservoir body portion with a coin-type slot therethrough for inserting and retaining soap chips. The reservoir body portion has a lowermost opening covered by a water absorbent body, typically a synthetic sponge. Thus, the primary function is for lathering and scrubbing the body either at a sink, wash basin or in a bathtub or shower. A secondary function is the thrift and savings to be realized with the reservoir body constituting a piggy bank for retaining soap chips coming from almost spent soap bars fed into the slot. A third function is that the soap dispenser may be in the ornamental format of a toy, sports item or other novelty. The construction provides advantages as a readily manufactured item formed from two basic pieces secured together.
Abstract: The present invention refers to a tubular escape system for buildings consisting of a combination of a platform, multiple uprights located around the perimeter of the platform to support the railings, a door connecting the building interior on that floor with each platform, a opening in each platform measuring 1.00 meter in diameter, two tubes that perpendicularly cross each platform and are connected to a water tank that can manually or automatically fill the tubes with water, an extension tube that remains fixed and inserted within the tube while the escape is not in use, a bolt that passes through the extension tube and so fixes it inside the extension tube, a sponge base to be found on each platform at the bottom of the section of tube on that platform, a cover attached to the base of the extension tube, an auxiliary ladder attached to the platform railings, an extension inside the tube that prevents anybody from entering by means of the opening on the lower platform.
Abstract: This invention provides for painting a second coat upon a set of parallel striped lines in exact registration in one pass of a motorized painting vehicle for such applications as painting aircraft taxi stripes at airports. Beads are also registered on one of the lines in the same pass. Provisions are made for maintaining registration about curved lines by steering around curves with a shortened wheelbase vehicle and by extending paint nozzles for striping a plurality of parallel lines, typically a center twelve inch wide yellow line between two six inch wide black lines, outboard from one side of the painting vehicle. The vehicle comprises two four wheeled units articulated together by a universal articulation joint permitting vertical articulation so that the leading and trailing wheels may be lifted off the ground to reduce the wheelbase for steering around curves.
Abstract: A rotary resolver having a stator housing with electromagnetic coils and a permanent magnetic rotor rotatable therein is improved to provide a resolver system with more precise angular rotor position readings. Interacting system features include a ring of soft magnetic material interposed between north and south magnetic pole structure on the rotor, which is enhanced in performance by a particular one of the soft magnetic materials RSi 24, RNi 8 and RNi 5. Adjustable compensation coil structure in the stator housing interacting with the rotor flux pattern obtains more precise angular readings in different working locations. A digital control system dynamically processes flux compensation information. Resolver units may be positioned at an end of a rotating shaft in a working position for detecting the angular rotation position of the shaft.
Abstract: This invention relates to a Neurological Stabilizer Device and is directed particularly to provide to the human organism a flux of electric current with the purpose of regulating, in certain cases and circumstances, the natural electric impulses of the human organism, in order to maintain them in a regular average with the objective to stabilize the general condition of the human. This body treatment device has an electrically conductive casing with an internal battery holder compartment arranged for extending conductive wire leads from positive and negative terminals of an internal battery in a manner adapted to contact the skin of a human body and conduct battery current through the body skin. One wire lead forms a latch to hold a battery removably within the compartment. The leads preferably are parallel wires spaced approximately three centimeters apart. A binding harness attaches the device to the body with the wire leads in contact with the skin to conduct battery current.
Abstract: A rear-drive, ride-on tractor propulsion unit is provided for articulation with manually steerable utility vehicles wherein a hydrostatic trans-axle transmission couples a gasoline motor to individual ones of two drive wheels about which the propulsion unit framework is pivoted. The drive wheels rotate about fixed axially aligned non-rotatable axles, and are independently driven by belts from the two axles of the transmission. In this manner, equal torque drive to the respective wheels is applied in one drive mode to maintain a preferred straight line drive path for the propulsion unit. For manual steering over a curved path the tractor unit permits a steerable three or four wheel utility vehicle to be pivoted about its rear wheels. A hydrostatic trans-axle transmission drive provides forward and reverse gears and braking. A low center of gravity provided by small wheels is made feasible by faster rotation speeds than the transaxle speeds afford.
Abstract: The mounting and stretching of a fabric cloth at a distance from a base proceeds by utilization of mounting bodies made of cardboard mounted adhesively onto the base. The cloth is stretched over the upper edges of the mounting bodies and is temporarily mounted by pins.
Abstract: A decorative ball display rack is formed of alphabetic characters, shaped and assembled in a self supporting array visibly displaying an abbreviated indicia identifying an institution sponsoring an athletic team, or the like, to present at least three upper receptacle tips formed by the letters and spaced to form a cradle for nestling and supporting a ball, typically a basketball, soccer ball or football.
