Abstract: A tool for applying grout into a recess between adjacent tile surfaces comprises a body for gripping by the user formed with an elongate, resilient channel member adapted for retaining a line of grout and delivering the grout directly into the recess by aligning and pressing of the channel member over the recess. A finishing portion can be formed on the same body or a separate body for compressing and shaping the grout after delivery into the recess. The tool of the present invention avoids wasting of grout and increases the speed of application without sacrificing the appearance or integrity of the grout joint.

Abstract: A coin collecting cart for collecting coins from parking meters. A plurality of bins are used, each bin being limited to a certain quantity of coins which quantity of coins is electronically sensed. When the first of the bins is full of coins, the coins pass to the second of the bins and so on. When the bins are full, they are individually removable from the cart and mountable within a frame located remotely from the cart. The bins are unloaded by manually rotating the frame together with the bin about an axis.

Abstract: A cutting and grinding tool for removing grout from between tiles comprises a rotatable cutting disc formed with a plurality of radially extending teeth about the circumference of the disc. A drive gear engagable with the teeth is rotated by a power drill to exert a drive force to rotate the cutting disc. The disc teeth serve a dual function of performing a cutting and grinding operation and transmitting the drive force of the drive gear to rotate to the disc. The tool is simple in construction, reliable in operation and easy to control in order to efficiently remove grout from between tiles.

Abstract: A hand held tool for the uniform compressing, forming and simultaneous cleaning of a previously applied bead of caulking or other similar fluent material from a constructed joint. The tool includes an elongated handle and triangular head with working edges, the working edges being essentially an arrow-like shaped pieced or rubber-like material fixed to and extending slightly beyond the acute isosceles triangular shaped head portion of the tool at the extremity opposite an elongated handle, the acute angle of the working edges at the extremity is slightly rounded. The head and the handle contain a continuous longitudinal cavity provided for the collection of excess material gathered during the operation of the tool and in the preferred embodiment the head and handle are essentially molded as one unit in resilient plastic material with the handle expanding in a fan-like shape the outer angles of the head.

Abstract: A saw arbor formed of a mandrel and a cylindrically apertured sleeve. Circumferentially spaced splines are provided around the mandrel's outer circumference and around the inner circumference of the sleeve aperture. The mandrel splines and the sleeve aperture splines are shaped and sized for slidable mating engagement of the mandrel splines with the aperture splines. Circumferentially spaced splines are also provided around the sleeve's outer circumference. The sleeve outer circumference splines are shaped and sized for slidable mating engagement with further splines spaced circumferentially around a saw blade eye. Equal numbers of equally spaced involute splines are preferably provided around the mandrel, around the inner circumference of the sleeve aperture and around the sleeve's outer circumference. The splines can be formed to achieve backlash tolerance engagement in the range of 0.001" to 0.

Abstract: A hand held tool for the removal of a cured bead of caulk, sealant or other previously fluent material from a joint between substantially perpendicular surfaces. The tool comprises an elongate handle with two working heads. The primary working head at one end of the longitudinal axis of the handle features a chisel-like point angled down from the upper face of the handle and extending between two symmetrical flanking planes which are acutely angled to each other and also spread from the body of the handle. The planes are bevelled to form sharp edges for scraping surfaces during an operation to remove a bead whilst the chisel-like point chisels the body of the bead from the joint. Axially opposite the primary head the second working head is essentially an angled chisel-like point extended from the upper face of the handle and is used to chisel, pick or gouge a bead from a joint.

Abstract: An apparatus secures at least two patient supports within a vehicle during transport, particularly adaptable within helicopters. Patient supports are secured to trays that are removably, telescopically connected to bases on a floor of a vehicle. The trays are telescopically, longitudinally, extended relative to the bases. Also, the trays are pivotally attached to a base for pivotal movement about an axis perpendicular to the floor, which includes an electric jack for moving the trays towards and away from the floor.

Abstract: A modular panel is described which has a flexible planar sheet form body with peripheral edges. Zippers are positioned along each of the four peripheral edges. The zippers along the peripheral edges of the body enable the peripheral edges to be mated with each other or other bodies to form articles of clothing, clothing accessories and the like.

Abstract: A method and apparatus are provided for securing medical equipment within an interior of an emergency vehicle, the apparatus including an elongated suspension bar (23) positioned within the emergency vehicle relative to a substantially planar surface (27) (25), and an equipment fastener (53) (110) for attaching thereto medical equipment (51). The equipment fastener (53) (110) for securing the medical equipment (51) to the elongated suspension bar (23) is preferably slidable along the longitudinal length of the elongated suspension bar (23). The equipment fastener (53) (110) includes a base block (77) (116) and a slider pinch block (79) (127), wherein the slider pinch block (79) (127) can be moved toward and away from the base block (77) (116) thereby releasing and securing the equipment fastener (53) (110) to the elongated suspension bar (23).

Abstract: A system for transferring patients to and from emergency medical vehicles and for securing the patients within the vehicles during transport is particularly adapted for helicopters, with at least two stations within the helicopter for securing two patients therein. The system accommodates standard stretchers or patient litters, including a first litter positioned in the first station in the rear of the aircraft approximately aligned with but above and behind the second patient station. In order to load the patients into the separate stations, interlockable trays and support plates are used. An upper tray is initially telescoped within a lower tray which, in turn, is supported on a carriage and lift assembly. The lower tray can be swung relative to the lift assembly to an oblique position pointed toward the exterior door of the helicopter. In addition, the lower tray, with the upper tray supported thereon, can be raised so that the upper tray can be slid rearward into the second station.

Abstract: A visual stimulator for light stimulation of a subject's eyes to obtain electroretinogram, electro-oculogram or visually evoked potential responses. The stimulator comprises a light directing means for directing light from a light source into the subject's eyes, attenuator means for selectably attenuating the light source, photodetector means for producing an output signal representative of the radiant energy directed into the subject's eyes and signal processing means for receiving and processing the output signal to derive therefrom further output signals representative of the radiometric or photometric characteristics of said radiant energy. A light shutter comprising first and second shutter leaves affixed to the shafts of first and second galvanometers is also provided. The shutter leaves are positioned for pivotal movement with the galvanometer shafts to attenuate light passing between the shutter leaves.
