Abstract: A log feed roll for displacing a log has a roll which may be rotated around a rotary axis, flutes for propelling the log, and removable flute attachments fastened to the flutes for contacting the log during engagement of the log in the feed roll. The flutes have flute apertures extending through side walls thereof. The attachments have a top attachment section from which generally opposed side braces extend. The attachments are fastened to the flutes by bolts extending through the brace apertures on one side brace, the flute apertures and the brace apertures on the opposing side brace, and nuts engaged on the bolts on the opposing side brace. The side walls are situated between the side braces, in abutment therewith when the attachment is fastened to the flute.

Abstract: A nasal cannula is supported on the crossbar of a generally U-shaped frame having bows adapted to extend rearwardly along the sides of a patient's head and adapted to rest on the patient's ears. Clips on the crossbar and the bows support flexible tubes for supplying oxygen to the cannula. A strap is connected to the bows and contracts around the rear and sides of the patient's head to help hold the frame in place.

Abstract: A spanner wrench is clamped to one component of a conventional pair of pliers and is prevented from turning relative to that component by the same pivot element which pivotably connects the two plier components to one another.

Abstract: A relatively large water bottle is blow molded from thermoplastic material and includes a generally cylindrical body, a generally frustoconical top breast at the upper end of the body, and a filling and dispensing neck extending upwardly from the central portion of the top breast. Angularly spaced reinforcing ribs are formed on the inner side of the top breast to increase the column strength thereof. The ribs are formed as an incident to blow molding the bottle from a preform having angularly spaced external ribs on a frustoconical portion of the preform, the external ribs being converted into internal ribs during the blow molding operation.

Abstract: The tap includes a lower body adapted to slide radially onto the neck of a container and lock beneath a lip on the neck. Connected pivotally to the lower body is an upper body having means for opening valves in the neck when the upper body is swung downwardly relative to the lower body to a tapping position. A releasable latch is carried by a handle on the upper body and automatically latches the upper body downwardly against the lower body when the upper body reaches its tapping position.

Abstract: A preform injection molded from PET includes a frustoconical section whose outer surface is formed with a series of angularly spaced ribs. When the preform is converted into a bottle by a blow molding operation, the frustoconical section of the preform is converted to a frustoconical top breast for the bottle while the external ribs of the preform are converted into internal ribs which are spaced angularly around the inner side of the top breast to increase the column strength thereof.

Abstract: A beverage tap includes a probe with a cylindrical upper section and a reduced-diameter cylindrical lower section. In order to seal the probe with respect to a Sankey-type keg fitting, an elastomeric seal includes a tubular body attached to the upper section of the probe and formed with a downwardly flaring sealing fin on its lower end. An apertured sealing disc is attached to the lower section of the probe and is located within the tubular body. Angularly spaced webs are molded integrally with the body and the disc and join the two together as a single unit.

Abstract: A closure for a container such as a container of draft beer includes two sealing plugs having bores for receiving the gas and beer tubes of a tapping unit. Initially, the bores of the plugs are sealed by rubber membranes which are adapted to be pierced by the tubes as an incident to tapping the container. The bores and the membranes are constructed so as (A) to effect piercing of the membranes with a controlled tear so as to avoid punched-out rubber slugs, (B) to eliminate the need of flappers for re-sealing the bores, and (C) to reseal the container at moderate pressures while enabling venting of the container at extremely low and high pressures.

Abstract: A tap for use with a container closure of the type having a pair of resilient sealing plugs. The tap includes a body which supports spaced product and gas tubes adapted to be thrust through the resilient sealing plugs of the closure. When the tap is removed from the container, the gas tube separates from the tap body and remains in the respective sealing plug so as to vent pressure in the container safely to atmosphere. Stabilizing fins extend downwardly from the tap body and engage the top of the closure to help hold the tap in a secure vertical position on the container.

Abstract: A tap for a beer keg having a Sankey-type fitting with radially inwardly extending lugs which normally are used to hold a conventional tap in a locked position on the keg. To prevent the locking lugs of the fitting from being damaged or to permit use of the keg after the lugs have become worn or damaged, the present tap includes a radially expandable and contractible collar adapted to lock onto the external lip of the fitting. The collar is formed by two camming clamps connected to swing about a hinge and adapted to float angularly relative to the body of the tap in order to permit the clamps to center themselves on the fitting. As the clamps are closed, they cam against the external lip of the fitting and force the tap downwardly to open the valves of the fitting.

Abstract: A fitting for a container of draft beer or the like includes a first valve for permitting pressurized gas to be injected into the container and a second valve for permitting beer to be dispensed from the container. Both valves are urged to their closed positions by inexpensive elastomeric springs which also serve to hold certain components of the fitting in assembled relation. A coupler attaches the fitting to the container and enables the container to be used with Sankey-type taps.

Abstract: A combined pump and tap assembly for a beverage container includes a cylinder for a hand pump and a gas tube projecting downwardly from the bottom wall of the cylinder and communicating with the interior of the latter. A hollow boss rigid with the bottom wall provides a connection for a downwardly projecting draw tube and a fitting for a dispensing hose is rigid with the boss and communicates with the draw tube through the boss. The cylinder, its bottom wall, the boss and the fitting are made as an integral unitary part so as to effectively preclude the user from disabling the hand pump and connecting the gas tube to another pressure source which may be unregulated and cause the container to explode.

Abstract: A hand-operated pump includes a cylinder and a reciprocating plunger. The plunger is made from plastic and includes a piston, a stem and an enlarged hand grip which are all molded integrally with one another so as to form a one-piece unit. The end of the cylinder is closed by a pair of separable caps which are adapted to be slipped sidewise onto the plunger and attached to the cylinder after the plunger has been assembled with the cylinder.

Abstract: The closure is an improvement over that shown in our U.S. Pat. No. 3,592,351 in that the present closure is capable of accommodating a tap with non-coaxial gas and draw tubes which make the tap effective for use in series tapping systems.
