Abstract: A retaining system for several items includes several group retaining structures, each group retaining structure having an item holding structure for retaining a group of related items; a collective mounting structure including mounting rails having fasteners for fastening to a mounting surface and having rail engaging structures for releasibly engaging and supporting several of the group retaining structures so that items retained on the group retaining structures are collectively displayed and individually accessible; and a group retaining structure carrier having carrier engaging structures for releasibly engaging and supporting at least one group retaining structure, the group retaining structure carrier having a carrier handle permitting a user to grasp and carry the group retaining structure carrier and any attached group retaining structure.

Abstract: An improved medical slide holder for use in medical procedures including automated microscopy. The slide holder comprises a rectangular frame adapted for receiving slides of differing thicknesses. Compensation for differing thicknesses is achieved through the disposition of two fastening caps, one for each end of the slides, the caps having resilient extending fingers which contact upper surfaces of the slides near their ends. Precision positioning of the slides within the holder is facilitated through provision of slide-supporting ledges having partitions to define positions of the slides; and precision positioning of the holder frame is facilitated through the provision of angled corners and notches each having a right angle and an obtuse angle. The slide holder has a recessed indentation in both the upper and lower locking caps to facilitate their removal once engaged to the frame, thus allowing slide specimens to be removed from the slide carrier for archiving purposes.

Abstract: A manifold for use with an inflatable article such as a life raft, life vest, and other articles used in aircraft and marine safety and the like, an improved puncture pin and dual cam drive system for positive control of the puncture pin, an improved means for positioning the cam lever arm, an improved positive dynamic seal of the puncture pin, and an emergency bleed system in case of puncture failure. The manifold body is preferably an integral molding of strong and impact resistant plastic material with a continuous passage within the molded plastic that provides a path for the compressed gas of the attached cartridge to flow to the desired article to be inflated, eliminating any possible areas of leakage.

Abstract: An object of this invention is to provide an emergency drain for units such as air conditioners and the like, operative to collect fluid and shut off the unit when the primary drain for the unit becomes obstructed, thus protecting against damage due to overflow of the fluid, and wherein a low pressure is produced in the drain for evacuating fluid from the drain pan of the unit. Another object is to provide a one-way valve in the drain from an air conditioner or other appliance, whereby reverse flow of air or other fluid from the drain to the unit is prevented. The emergency drain comprises a fitting (11) mounted in the drain pan (14), with a primary drain opening (16) and a secondary or emergency drain opening (17) for draining away fluid accumulated in the pan when the primary drain becomes blocked.

Abstract: A multiple-unit dispenser is disclosed including two side-by-side containers having mouths at their upper ends and openings at their lower ends, with a valve at each of the openings for controlling the dispensing of liquid products. A single unitary lid covers both the mouths at the tops of the containers. The containers are both parts of a single, unitary housing which is mounted on a wall bracket. Preferably, the wall bracket has upper and lower fingers which grasp the housing, and the lid has a downwardly extending projection which retains the upper finger of the bracket so that the upper finger cannot be released without removing the lid, thereby locking the housing on the wall bracket.
