Abstract: An apparatus for evaporating liquid samples contained in sample holders mounted within a chamber and by rotated by the rotor during an evaporation process in which the pressure in the chamber is reduced below atmospheric and the sample holders are rotated at high speed so as to exert centrifugal force on the contents of the holders. Heat is supplied to elevate the temperature of the liquid component of the samples to assist in the evaporation process. The temperature of the sample material is continuously or regularly monitored during the evaporation process and temperature signals are transmitted to a remote computing means which is programmed to generate a control signal for controlling the supply of heat to the samples and controlling the evaporation process. The temperature may be sensed by a probe in a sample holder containing an evaporating liquid sample, or in an adjoining sample holder containing a buffer liquid. The rotational speed is also sensed and a speed signal conveyed to the computing means.

Abstract: A disposable glove dispenser bracket includes a back panel with a magnetic pad attached thereto for supporting the dispenser and lateral side panels with flanges to grip and hold a glove dispenser box. A biasing spring maintains the glove dispenser box appropriately positioned within the dispenser bracket.

Abstract: A lottery number selector is provided and consists of a set of numbered cards so that a series of numbers can be selected at random for a state lottery drawing. A dispenser device can be used to hold at least one set of randomly mixed numbered cards so that a person can remove the top cards one at a time. The dispenser device is rotatable about its base and has a mechanism for recording the numbers selected when each card is removed.

Abstract: A card dealer wheel assembly having a rotatable adjustable extension arm is provided which is selectively adapted for use on various sizes of card tables so as to selectively deliver cards proximate to card players positioned around the perimeter of a card table. The elongate rotatable adjustable extension arm is provided with a plurality of spaced-apart adjustment holds therethrough which extend longitudinally therealong from one end thereof. A card holder and dispensing assembly is fixedly mounted at the end of the adjustable extension arm opposite the adjustment holes provided therethrough. A central support base member is provided for selective rotatable supporting engagement with the elongate adjustable extension arm so as to permit selective incremental rotation of the card holder and dispensing assembly between card player positions around the perimeter of a card table.

Abstract: A mini-card rotary file structure and system which includes a rotor support and a rotor spanning the support with a plurality of card tray support fins arranged in intersecting chordal planes on the rotor and slidably removable mini-card holder and transfer trays engaging the fins and wherein the trays are provided with tracks to engage recesses in mini-cards to be slidably captivated by the tracks on the trays for rotation with the rotor into and out of a generally tilted and horizontal attitude and wherein a base or several bases may be provided to support mini file card holder and transfer trays removed from the rotor for convenient arrangement of one or several trays at one or several work stations.
