Abstract: The present invention is directed to an animal actuated drinking apparatus allowing animals to obtain liquid therefrom.      The invention is directed to an apparatus, a kit, and a method of providing for an animal actuated drinking apparatus. The animal actuated drinking apparatus of the present invention includes a tubular body having a fluid passageway therethrough; an annular valve seat positioned within the fluid passageway, and an o-ring of resilient material seating against the annular valve seat. A valve actuator stem is adapted to seat against said o-ring and in sealing engagement therewith. An elongated, generally cylindrical, elastomeric compression biasing sleeve of resilient material being in pressure contact with the valve actuator and maintaining the actuator in a neutral position. Displacement of the actuator stem from the neutral position causes fluid to flow through the apparatus. The replacement kits may be fitted with one or two piece actuators.      The method of the present invention includes replacing a conventional spring biasing member and associated actuator in a conventional animal actuated drinking apparatus with a valve actuator stem having a transverse slot therein, and an elastomeric compression biasing sleeve of resilient material having a fluid passage therethrough.

Abstract: Method and apparatus for workpiece grinding comprising rough grinding using an abrasive wheel and finish grinding by means of an abrasive belt wherein the workpiece remains within the grinding station throughout the grinding process. The apparatus consists of a grinding wheel (10) and an abrasive belt (26) whereby the wheel and belt are movable towards and away from the workpiece so as to allow for rough and finish grinding without removal of the workpiece. In an alternative embodiment a grinding wheel (50) is mounted on a wheelhead (92) together with a belt grinding facility and rotation of the wheelhead (92) about an axis (108) causes the grinding belt (72) or the wheelhead (50) to be presented to the workpiece. Another embodiment allows for a grinding belt and wheel to be adjacent, alternative wheel and belt operation being achieved by use of a supporting arm (116) which alters the belt position. A final embodiment allows for a belt (120) and wheel (122) on separate supports (124 and 126), on opposite sides of the workpiece and independently movable from opposite sides thereof into contact with the workpiece.

Abstract: The invention provides a method and an arrangement for selecting a free link for a requested connection from among a plurality of available links coordinated to form a route in accordance with the particular resource requirement of the requested connection and in dependence on the current resource seizure of connections that have already been established on utilized links, wherein the requested connection and the connections that already have been established have the same or different resource requirements. The current resource seizure for each link resulting from the established connection or connections is stored in a memory. Each link is sorted in the memory in one of a plurality of link-allocated memory sites which correspond to the current resource seizure of the link or the free or unused resource capacity of the link. The memory sites are ordered in the memory in accordance with a link capacity associated with each memory site. Upon occurrence of a requested connection having a particular resource requirement, a memory site is chosen depending on the particular resource requirement. Whether the chosen memory site and a link associated therewith has free capacity for the particular resource requirement then is evaluated.

Abstract: A replaceable pick-up tooth assembly for a crop pick-up comprises a plurality of pick-up teeth integrally molded to and with a substantially C-shaped flexible mounting unit. The pick-up teeth have a greater height dimension in the direction of rotation of the raking pick-up, and taper in height dimension from a base end at the mounting unit and a tip opposite the base end. The thickness of the teeth in the lateral direction perpendicular to the direction of rotation is much smaller than the height dimension at the base end. This provides added strength in the direction of rotation yet permits flexibility in the lateral direction along the axis of rotation. The pick-up teeth rotate in a plane perpendicular to the axis of rotation and parallel to the direction of rotation, and are concave in the direction of rotation with a large radius of curvature to provide added efficiency and accuracy in pushing up crops. The C-shaped mounting unit snaps onto a mounting bar of a crop pick-up.

Abstract: A conformable, self-aligning, high extraction efficiency tea filter pack (1) capable of flavor extraction efficiencies comparable to those obtained using an identical quantity of bulk tea leaves and a paper filter under identical brewing conditions, but which exhibits s ubstantially consistent pot-to-pot brew strength for any given automatic drip coffee make r. The preferred filter pack is formed from two layers ( 10, 20) of flexible material which are secured to one another about their outerm ost periphery with a predetermined quantity of tea leave s (50) housed within a brew chamber (40) formed between the two layers (10, 20). Th e brew chamber (40) exhibits a maximum volume between about 100 percent and about 400 percent greater than the volume of the dry t ea leaves contained therein. The discharge flow rate (F3 ) from the brew chamber is slower than the inlet flow rate (F1) into the brew chamber to permit a buildup of water and flooding of the brew chamber (40). The flexible conformable side wall surrounding the brew chambe r (40) extends upwardly a vertical distance which is at least sufficient to capture enough hot water to totally immerse the brew cha mber (40) when the brew chamber (40) is in its fully exp anded condition. This causes the tea leaves (50) within the chamber (40) to expand andfloat throughout the remaining portions of the brew cycle, thereby establishing a steady state brewing condition which is highly effect ive in maximizing tea/water contact as the hot water pas ses through the brew chamber (40) on its way to the pot.
