Abstract: An connection apparatus is provided for connecting a ram of a pusher vessel with a receiver installed in a stem notch of a barge, the connection head for mounting on the ram having a generally pentagonal shape and the receiver having two opposed side walls with one side wall being flat and the other side wall having projecting teeth.

Abstract: A method of using a penetrating protective sealer to mark a message onto a porous surface is provided. Once the sealer has been applied to the surface and is allowed to dry, the message will not be visible. An indicator dye can be used to aid in application of the sealer; once the sealer has fully cured, the indicator dye is no longer visible. When the marked surface becomes wet, the portion of the surface that has been treated by the sealer will repel water; the remainder of the surface will absorb water and turn dark. The contrast in color created between the darker, untreated/wet, surface and the lighter, treated/dry, surface will result in a visible message to an observer. The message can be a warning or an advertisement. A thickened penetrating sealer composition and a method of using the same is provided. The thickened sealer results in neat, clean, crisp edges for the message.

Abstract: A custom display storage system includes storage and display assemblies. The storage assembly includes an album or scrapbook containing pages for mounting graphic works and other generally planar objects. The display assembly includes a display unit joined at the edges with a backing to form a pocket. The display unit includes openings for display of custom character strings as well as graphic images. The backing includes a slot providing access to the pocket. A base sheet having a guide grid for mounting images, including a string of preprinted character units may be slid through the slot and into the pocket in alignment for display via the front display unit openings. Alternatively, the system may include a container for storing three dimensional items as well as graphic works. The custom display storage system may also comprise a kit with a selection of character units and an album or storage container with a variety of display units.

Abstract: A cream carrier is provided which has use as a cream-type carrier for topical delivery of medicaments including analgesics. The carrier comprises a mixture of: squalane NF, an emulsifier such as Tween 80, glycerin, cetyl alcohol NF, glyceryl monostearate, lecithin organogel preserved, BHT, urea USP, EDTA, water, stearic acid, simethicone USP, and ethoxy diglycol reagent. The invention also comprises a combination of the carrier, with either or both of ketamine hydrochloride and amitriptyline hydrochloride, which has use as a topically applied analgesic.

Abstract: A tire pressure monitor method enables the reassignment of tire pressure sensors to respective tire locations on the vehicle in the event that the sensors are lost or replaced with new sensors having differing identification codes. A passenger compartment monitors, that normally monitor tire pressures through broadcast transmission from the sensors, is manually put into an identification entry mode selecting a desired tire location, and when the vehicle begins travel, a motion switch in the new sensor detects vehicular motion and activates the transmission of the new identification code that is received by the monitor that then assigns the presently selected tire location to received identification code.

Abstract: An apparatus is provided for oral fluid collection from the mouth the apparatus having a fluid resistant shield adjacent one portion or side of the absorbent to support the absorbent after the absorbent is moist with oral fluid and the shield further operating to block the collection or mucosal transudate from the gum and teeth margin. A method of collection saliva while excluding the collection of mucosal transudate is provided wherein blocking of a portion of an absorbent is performed and the blocked portion of the absorbent is placed adjacent the teeth and gums to exclude any direct collection of mucosal transudate.

Abstract: A headband is provided for holding a wearer's hair in a desired position. The headband includes a top portion and two opposing side portions extending in a generally orthogonal direction from the top portion. The orthogonal shape of the headband increases the volume between the wearer's head and the headband. The increased volume provides an aesthetically pleasing, non-compressed and natural appearance for curly, thick or full-bodied hair.

Abstract: The invention comprises an openable and closable storage unit (1) adapted so as to be capable of enclosing a folded-up display unit (2), consisting of one or more stand parts and one or more information-carrying sheets, screens or the like, first and second end-wall parts (11, 12) which belong to a wall part (10), said wall part (10) being arranged to, in cross section, form a cross-sectional area following one or both said end-wall parts (11, 12). A first storage space (5) is given a circular or in any case essentially circular cross section by means of part-circular units (7) which are formed in plane wall sections (10b) or applied thereto. A second storage space (6) is given a semi-circular or in any case essentially semi-circular cross section by means of units (8) which are formed in or next to said plane wall sections or attached thereto.

Abstract: A device and method for positioning a patient at various angles of incline and decline is provided which permits patient positioning at accurate, reproducible angles of incline and decline and which allows variable speed raising and lowering of the patient and emergency lowering of the patient while permitting repositioning of the device while accounting for variations in the table mounting surface in achieving accurate and reproducible angles of incline and decline.

Abstract: An apparatus is provided for diverting sound from a direction generally rearward of a user towards the user's ears. The apparatus includes a sound reflector which can be worn by the user directly or connected to a separate mount such as a helmet. A connection between the sound reflector and the helmet may be fixed or adjustable. An adjustable connection may be removable or permanent. When a helmet mount is used, the apparatus can include a splitter positioned between two sound reflectors. The splitter directs sound to each of the two sound reflectors. The addition of buffer pads aid the sound reflectors in deflecting air around the user's ears to reduce wind noise and increase the user's ability to hear sounds originating from the rearward direction.

Abstract: A batting swing device is presented which enables a batter to determine whether or not his swing is good or bad. The device is designed for use by both baseball and softball players. It is intended to teach hitters the correct path that a bat must travel during a swing in order to most effectively hit a ball to all parts of a playing field. The device is approximately 5 inches in outer diameter and three inches in inner diameter, and shaped similar to a doughnut. The inner diameter is flat to enable the device to easily slip on and off a baseball bat. The device is made of polyethylene plastic and weighs approximately two ounces. When a batter takes a swing with the device slipped onto the bat and above the batter's hands, the direction of travel of the device will determine whether or not the batter has made a good swing. If the device travels towards the pitcher's mound, or within a 50 degree angle measured off of the pitcher's mound, the batter's swing was a correct one.

Abstract: A method of removing contaminates from ground water is provided which places a biological permeable barrier in the path of the ground water flow to contact the contaminated groundwater with encapsulated microorganisms which act to decontaminate the contacted groundwater.

Abstract: An adjustable mold is provided for vacuum assisted drawing of a thermoplastic material into the mold to form a dunnage tray, the mold being water cooled and allowing adjustment of the mold sides and surface topography to allow rapid and inexpensive user adjustment of the mold to from a variety of dunnage tray sizes and shapes as selected by a user.

Abstract: An apparatus is provided for use with a mobile air blower which allows the blower air stream to be oscillated vertically or redirected away from the work piece to avoid damage to vehicles and structure that are in the path of the air blower air stream and the apparatus provides for redirection of the air stream in forward and rearward directions.
