Abstract: An apparatus which dispenses a static centerflow rolled sheet product. The rolled product is disposed within a housing defined by a front side, back side, and side walls. The front side includes an opening through which an end of the rolled sheet product is pulled. A protrusion is defined, for example, on the back side member and extends towards the front side within the housing. The protrusion is disposed and has a length so as to extend into the rolled sheet product center void a sufficient distance to prevent the rolled product from collapsing on itself as the sheet product is withdrawn.

Abstract: Adapters for solid or coreless rolls of material dispensed in a roll dispenser, which may have slots defined on the side walls thereof. The adapters may have a base body with a first side disposable adjacent to the roll and a second side disposable adjacent to the side walls of the dispenser. A protrusion may extend substantially transverse from the first side and may have a shape and length so as to extend at least partially into a recess or divot formed in the vertical sides of the rolls. An engaging member may extend substantially transverse from the second side of the body member and may have a shape and a length so as to be insertable into and slidable along slots disposed in the dispenser. A pair of the adapters may engage and hold the roll therebetween within the dispenser and may allow for the roll to move along the slots defined in the dispenser to a dispensing position.

Abstract: Disclosed is a theft deterring countertop mounted fluid dispensing system for dispensing liquid soap using a liquid soap dispenser which can be disposable. The system includes a base unit or module adapted to be permanently affixed to a countertop. The base unit includes a locking mechanism and at least one lug orifice. The base unit is used in conjunction with the fluid dispensing unit or module which includes a bottle for storing the liquid soap and a lug extending from the bottle, The lug is receivable in the lug orifice of the base unit and releasably engaged by the locking mechanism therein. A key or series of movements which are not readily obvious to a casual user of the product are required in order to remove the fluid dispensing unit from the base unit.

Abstract: A centerflow dispenser for dispensing a rolled paper product which includes a device for varying the diameter of the dispensing orifice to accommodate rolled paper products of various weights, widths, bulks and tensile strengths. The dispenser includes a rear housing, a front housing pivotally attached to the rear housing, the rear housing having extending therefrom a support member or bottom housing upon which a rolled paper product is placed. In one embodiment, the support member has attached thereto a rotatable disk with a plurality of a different diameter orifices disposed in the periphery thereof. The disk can be rotated such that each orifice in turn comes in at a vertical overlapping relationship with an exit port in the support member. In such manner, the desired orifice can be selected for the particular paper product being dispensed.In a second embodiment, interchangeable U-shaped members are supplied, each having a different diameter orifice therein.

Abstract: Disclosed is a theft deterring countertop mounted fluid dispensing system for dispensing liquid soap or other ruscous fluid using a liquid soap dispenser which can be disposable. The system includes a base unit or module which is to be permanently affixed to a countertop. The base unit includes a locking mechanism and at least one lug orifice. The base unit is used in conjunction with the fluid dispensing unit or module which includes a bottle for storing the liquid soap and a lug extending from the bottle. The lug is adapted to be received in the lug orifice of the base unit and releasably engaged by the locking mechanism therein. A key or series of movements which are not readily obvious to a casual user of the product are required in order to remove the fluid dispensing unit from the base unit.

Abstract: A contact assembly and method for vapor liquid contact towers employing a round aperture cover secured above a contact tray by integral depending legs, the upstream leg being of greater width than the downstream leg.

Abstract: A valve-tray assembly for vapor liquid contact towers. The active area of the tray beneath an upper downcomer is constructed with directional thrust valves facilitating oriented vapor flow therethrough and improving mass transfer efficiency. The valves include first and second support legs oriented into the liquid flow with the first leg having a wider surface area presented to the flow for diverting the flow therearound. The width of the first leg is less than the diameter of the valve aperture, about which the liquid is induced to flow into engagement with the vapor passing therethrough. The valve assembly is used in conjunction with, and outwardly of, a raised active inlet area to further control initially directed liquid flow from the perforated inlet area beneath the downcomer.

Abstract: A cabinet for dispensing a sheet of paper from a stack of paper sheets in the cabinet. Means are provided in the cabinet for restricting the length of the stack of paper that can be placed in the cabinet when the cabinet is open. The restricting means is movable to a pressure relieving position when the cabinet is closed.

Abstract: The present invention relates to a computer system having a sequence controller for allowing direct memory access devices to access peripheral devices. The sequence controller allows the peripheral devices access to a global bus by providing access in a round-robin fashion. A microprocessor associated with the sequence controller and direct memory access has access to the global bus after each direct memory access. The amount of data allowed to be transferred in each direct memory access is restricted so that each device is equally serviced.

Abstract: A universal peripheral controller is disclosed which uses DMA devices to provide access between a plurality of peripheral devices and other circuits within a computer system. A processor in the computer system recognizes a request from the controller to connect a peripheral via the system bus to another circuit connected thereto and establishes the connection. The processor then passes information to the controller and leaves the task of controlling the transfer of information to the DMA circuitry in the controller. The controller has a sequencer which examines each of the plurality of peripherals connected to it in a round robin operation to determine which peripherals are requesting a connection via the computer system bus to transfer information. The sequencer limits the time each peripheral can be connected to the system bus before servicing another peripheral request in order that all peripherals have equal access to the system bus.

Abstract: In a computer system having at least a bus with at least one central processing unit (CPU), one random access memory (RAM), and a first configuration of a plurality of different types of peripheral units (e.g. tape drives, disk drives, diskette drives, printers, unit record peripherals, etc.) coupled to the bus, an apparatus for controlling the first configuration and also capable of controlling a predetermined number of other configurations of different types of peripheral units when any of that predetermined number of configurations of peripheral units is coupled to the bus.

Abstract: A dental handpiece is disclosed having at least two connectable portions and having a substantially rigid connection between the two connectable portions, there being resilient means forming a portion of the substantially rigid connection. The resilient means inhibits transfer of vibration from one of the connectable portions which contains a gas-driven motor to the other connectable portion which provides a hand-grippable surface.

Abstract: An air driven dental handpiece comprising a handle and a turbine housing mounted at one end thereof. The turbine housing includes a rotor having rotor blades and ball bearings for rotatably mounting the rotor. A port is formed in the handle, which is in fluid communication with the interior of the turbine housing. A lubricant is injected into the turbine housing through the port. Removable sealing means cover the port to prevent any foreign matter from entering the turbine housing and to prevent air from leaving the port.
