A combination gravimetric and volumetric fluid dispenser is disclosed which includes a scale linked to a controller. The controller is linked to a plurality of two stage valves which control the dispensing of large quantities of base materials. The controller is also linked to a plurality of nutating pumps which together with the controller controls the dispensing of smaller quantities of additive materials. The dispensing system disclosed is particularly useful for paints or other liquid formulations where larger quantities of base materials are added and which can be added by weight and whereby precise measurements of the larger base materials is not particularly required. However, the incorporation of nutating pumps and the addition of smaller amounts of additives by volume using the nutating pumps enables precise dispensing of the additives, such as colorants for paint. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus. The dispensing apparatus is also preferably designed with a modular configuration as shown and described. For viscous materials, an improved dispensing method is disclosed whereby viscous base material is added to the container first followed by smaller amounts of additives followed by additional dispensing of viscous base materials. By sandwiching the smaller amounts of additives between layers of base materials, an improved mix ability results for viscous materials such as base materials of paints and colorants.

A gravity bolus feeding device having a cylindrical body with and intake valve to control or prevent flow of fluid through the feeding device. The device also has a check valve to receive fluids expelled from the patient back into the feeding device. The check valve allows such fluids to rejoin the fluid path and be re-fed to the patient, while allowing air to vent. A burp baffle for use with this or another feeding device to prevent spillage or splashing, while taking in or venting air. The burp baffle has a bottom section which snugly fits into the device, with a notch or opening near its outer periphery, allowing fluid to pass. A center section connected to the bottom section allows fluid to flow around it and into an opening generally opposite the notch. A top section covers the feeding device, and has a hole that allows fluid to vent out the top of the feeding device.

However, the incorporation of nutating pumps and the addition of smaller amounts of additives by volume using the nutating pumps enables precise dispensing of the additives, such as colorants for paint. The base material dispensing valves include stepper motor actuators having multiple steps per revolution. The stepper motor actuators are under the control of an analog signal from a controller. The base material dispensing valve is opened or closed via a rod that is slidably raised or lowered upon rotation of the drive shaft of the stepper motor actuator. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus. The dispensing apparatus is also preferably designed with a modular configuration as shown and described.

A fluid sample collection system includes a vial, a plunger and a fluid sample collection device having an absorbent for absorbing and retaining a fluid sample therein. The plunger includes an elongated handle portion and a plunger head portion detachably connected to the handle portion. The plunger also includes a splash guard supported on the handle portion. During the sample collection process, the saturated absorbent from the sample collection device is placed into the vial and the plunger is then advanced toward a closed end of the vial to express the fluid sample from the absorbent. The plunger head portion is retained within the vial with the absorbent in a generally compressed state and the handle portion is detached and removed from the vial.

A gutter cover which can be more easily installed over a gutter without the use of siding breaks or other clamping tools. The gutter cover comprises a generally planar first section adapted to be installed under or over a row of shingles on a roof; a generally planar second section adapted to overlie the open end of a gutter; and a bend between the first and second sections. The bend is shaped and configured to permit the angle of the first section to be easily adjusted relative to the second section without the use of tools and to slow the flow of water from the roof through capillary action. The bend is generally V-shaped in cross section and includes a first leg that depends from one edge of the first section and a second leg that depends from one edge of the second section. The two legs are joined at the bottom to form a crevice that slows the flow of water over the gutter cover.

A method and apparatus for polishing a substrate with a polishing pad and slurry entails washing polishing-pollutants produced by the polishing operation off of the pad in such a way that the pollutants are not splashed onto components of the polishing apparatus. A washing solution for removing the pollutants is directed onto the polishing pad as at least one free-flowing vertical stream. Because the washing solution flows freely and vertically as it impinges the polishing pad, the washing solution does not rebound from the pad and flows from the surface of the polishing pad without causing the pollutants on the pad to be splashed up from the surface of the pad.

A urinal uses a sloped interior back wall to create a specific angle between an incoming urine stream and the back wall to effect an anti-splash phenomenon which involves the contact angle hysteresis and the coanda effect, thereby at least to minimize urine splashing. The contact angle hysteresis deals with the perpendicular angles at which the urine stream comes into contact with the back wall of the urinal bowl, that is the amount of angle degrees between the angle of surface of the bowl and the angle of the urine stream at the point of contact. This angle takes advantage of the Coanda effect so as to cause the fluid (urine) to run down the surface of the back wall to the bottom of the urinal, rather than splashing back. The Coanda effect is the tendency of a fluid jet to stay attached to an adjacent curved surface that is very well shaped. In one embodiment, the interior back wall is vertically sloped towards the user, at an angle greater than 20° from the vertical (e.g., 30° to accommodate a 60° urine stream), and the back wall may be further curved from side to side. In an other embodiment, the interior back wall has a undulated top-to-bottom or vertical contour.
