  • Patent number: 6076904
    Abstract: A dispensing cabinet has a rear panel, left and right transverse side panels that define a front access opening for the cabinet and a bottom access opening for the cabinet. At least one door is provided to selectively close the front access opening but the bottom access opening remains open. A longitudinally extending rail is mounted on the rear panel and, in a preferred embodiment, extends horizontally to slidably support at least one dispenser in an operative position which is adjacent to the bottom access opening. The dispenser has a bottom opening for dispensing selected articles and these are accessible for use through the bottom access opening. Normally, the door covering the front access opening will be shut and the dispensers are hidden from view. The dispensers are removable from the rail so that selected dispensers may be used according to the nature of the dispensed articles which are required.

  • Patent number: 5997297
    Abstract: A method of mounting tools used in dentistry, the tools having flexible tubes associated with instruments remote from the tools, in which a redirector bar is mounted to a bottom surface of a bench top between tool receiving brackets and the instruments so as to support the tubes and define a forward loop and a rearward loop. The tubes in the rearward loop are parallel while the tubes in the forward loop converge when they are extended to the mouth of a patient. Preferably, the tool receiving brackets are supported on the forward edge of a bench top which is slidably mounted for movement in a direction which is parallel to the rearward loop.
