Abstract: An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations. The arm support includes an armrest pivotally mounted on a slide or a shroud for sliding the armrest to and away from a base which is secured to a table or chair. The slide or shroud is pivotally mounted in the base such that the armrest, which is pivotal relative to the slide or shroud and slidable to and away from the base, is also rotatable about the base to provide for a wide range of fluid motion for the forearm. The armrest further includes a plurality of roller bearing arrangements for facilitation of the slide or shroud and arm support. The roller bearing arrangements engage the slide or shroud proximate to the housing to provide for the fluid movement of the slide or shroud. A shroud may also be provided for enclosure of the roller bearing slide arrangement to prevent inadvertent engagement between an individual and/or the individual's clothes and the slide.

Abstract: A method and apparatus for playing duplicate card games such as blackjack and poker. In operation, after shuffling an appropriately sized deck, each player is supplied with an identical first hand. From there, each player plays against the dealer or house directly and against each other indirectly. To ensure parity, the shuffled deck is duplicated in its exact order for each player so that each player uses the same identically ordered cards when playing against the dealer or house. Depending on how each player plays, the initially dealt cards (e.g., call, hold, etc.), the relative skill level between players may be measured. After each round played, the deck is reshuffled. A running total for all participants is maintained and each player may wager against the dealer or house in the normal fashion. The apparatus includes a processing unit connected to a plurality of displays each of which includes associated control buttons.

The lock has at least one flexible finger and a plurality of movable sleeves that allow one hand operation to selectively lock and release the jaws without substantial lateral displacement of the object. A plurality of locking stops is provided so that the jaws may be held closed at a variety to tensions, to accommodate a variety of objects.

Abstract: A constant light output ballast circuit capable of regulating lamp current to a substantially constant level independent of the number of fluorescent lamps on load. The circuit incorporates a power factor control circuit and an electronic ballast circuit having a secondary winding on its output transformer. The voltage on the secondary winding, which is proportional to the ballast circuit's output voltage, is fed back to the power factor control circuit to regulate the DC output voltage supplied to the electronic ballast circuit and thereby maintain a constant lamp current.

Abstract: A modular tubing support and constrainment device for supporting and constraining tubing comprising a plurality of modular support trays, a module connector portion and a clamping portion. The modular support trays each incorporate a bottom portion for supporting the tubing and side constrainment portions to significantly constrain the amount of snaking by the tubing. The modular support trays further incorporate a plurality of apertures which are used by the module connector portions to connect and join the modular support trays into a continuous single unit. The apertures are also used by the clamping portion so that the clamping block may be secured to the modular support tray. The clamping block has an arcuate bore therethrough that is sized to fit snugly about and constrain the tubing. The bore may be lined with an elastomeric material to provide extra tube gripping potential.

The containment vessel and slab with suspended tank being formed remote from the site of installation.

Abstract: A rotary spray fluid apparatus anchorable to a car wash structure which has an elongate body portion with a side inlet and a rotatable hollow shaft extending therethrough defining an annular space with fluid transfer region, a pair of sealing regions and a pair of bearing regions. The shaft has a port adjacent the side inlet extending into an axial passageway in the shaft to flow to a spray head. Each sealing region has a pair of sealing rings. One ring of each pair of sealing rings is sealed to the body portion and the other is sealed to the rotatable shaft. A spring positioned in the fluid transfer region of the annular space provides an axial compressive force to maintain engaging faces of the sealing rings together as the shaft is rotated thereby sealing the annular space relative to the fluid flowing to the spray head.

Abstract: A filter element for an air cleaner including a filter medium which has a plurality of basic filter units and is integrally formed of a porous sintered material produced by sintering powdered synthetic resin.

Abstract: An ergonomic arm support for supporting the forearm during typing, keying, or assembly operations.

Abstract: A process for measuring the vapor transmission rate characteristics of a test material by first measuring the vapor transmission through a test chamber and sample material and subsequently repeating the measurement with the test material adjacent the sample material. By subtracting the first measured transmission rate reciprocal from the second measured transmission rate reciprocal, a value is determined which is the reciprocal of the vapor transmission rate characteristic of the test material.
