Abstract: An apparatus for removing grease from a compartmental grease trap that has water provided therewithin so that grease forms a layer atop the water in the trap. The apparatus has a mounting portion that is securable to the grease trap and a housing portion pivotally connected to the mounting portion. A filter media is then secured by the housing portion. The housing portion is preferably constructed from a framing structure and an inner structure. The framing structure has two sets of opposed sidewalls and a perforated or mesh bottom sheet that allows water to pass therethrough. The inner structure is separably secured to the framing structure, such as by pivotal connection and the filter media is preferably held between the inner structure and the framing structure. The inner structure is capable of being locked into position with respect to the framing structure by a locking device.

Abstract: An apparatus is provided for moving a movable switch point a selected distance as a result of the throw of a switch machine. The apparatus includes an operating rod connected to and movable by the switch machine and a switch point adjuster mounted directly to the switch point and movable by the operating rod. The switch point adjuster has an elongated housing with a bore provided therethrough, in which the operating rod is disposed through the housing bore. The switch point adjuster also has first and second adjusting nuts that are adjustably secured to the operating rod on opposed sides of the housing, preferably by mated threading. The operating rod is movable bidirectionally through the housing until one of the adjusting nuts contacts the housing. In this way, lost motion of the switch machine may be compensated for. The adjusting nuts preferably have a head portion and a body portion, in which the head portion has a width greater than the width of the body portion.

Abstract: An adjustable golf shaft for a golf club which allows a child to use the same set of golf clubs during childhood and into his or her teen years. The golf shaft has a first shaft member, a second shaft member telescopically positioned within the first shaft member, and a compression fitting which fixedly attaches the first shaft member to the second shaft member at a desired golf shaft length. As the child grows, the compression fitting can be loosened, the second shaft member can be expanded outward from the first shaft member lengthening the golf shaft, and the compression fitting can be tightened fixing the first shaft member relative to the second shaft member.

Abstract: The present invention provides a method and device for ascertaining flow rate of a fluid based on measured values of the upstream fluid total-pressure and static-pressure measured downstream the entrance of a flow constricting member, such as an orifice plate, a flow nozzle or a venturi. According to principles set forth herein, this parameter allows simplification of flow rate determinations for both compressible and incompressible fluids. As a result, significant computational advantages may be achieved in comparison with the prior art. In presently preferred embodiments, a first pressure sensor means for detecting the upstream total fluid pressure includes a pitot-tube fluid-pressure sensor. In order to determine fluid density, a temperature probe may be provided to detect total temperature at the stagnation point created by the pitot tube. A second pressure sensor is also provided to detect the desired downstream static fluid pressure.
