Abstract: A flexible coupling for flexibly joining two rotating or moveable members includes a unitized body having a first end and a second end coaxial to each other, and therebetween having one or more coaxial longitudinally spaced disks with center holes; two or more axial spacing portions formed from the body of each disk to provide a spacing means and joining means for unitizing the disks to each other; means for joining the unitized disks to the first and second ends; and means at the first end for coaxially connecting to a first one of the two rotating or moveable members, and means at the second end for coaxially connecting to a second one of the two rotating or moveable members.

Abstract: According to the invention, a flexible coupling for flexibly coupling two rotating or moveable members, comprising a unitized body having a first end, a second end, and therebetween having two or more longitudinally (axially) spaced discs, wherein each disc can include a body portion and one or more spacer portions, wherein the spacer portions can extend longitudinally from an upper surface or lower surface of the body portion. The spacer portions can serve to axially space the body portions from each other and can also serve to unitize the discs and to space the unitized discs from the first and second end and can further serve to join the unitized discs to the first and second end.

Abstract: A diode (20), having first and second conductive layers (24,26), a conductive pad (28), and a distributed reverse surge guard (22), provides increased protection from reverse current surges. The surge guard (22) includes an outer loop (42) of P+-type surge guard material and an inner grid (44) of linear sections (46, 48) which form a plurality of inner loops extending inside the outer loop (42). The surge guard (22) distributes any reverse current over the area of the conductive pad (28) to provide increased protection from transient threats such as electrostatic discharge (ESD) and during electrical testing.

Abstract: An anchoring arrangement is provided for anchoring a dock leg to a bottom of a body of water. A base plate has a lumber or timber receiver on its top surface and has three or more anchor legs that are attached to the base plate and that extend downwardly. At least one of the anchor legs preferably has a fluke pivotally attached to it so that when the anchor leg is pushed downwardly into a bottom of a body of water the fluke pivots into contact with the anchor leg. A subsequent attempt to pull the anchor leg upward causes the fluke to pivot into an extended position in which it provides additional resistance to the upward motion of the anchoring leg. Most small docks have legs made of conventional lumber or timbers large enough to provide a buoyant force adequate to support thsi metal anchoring apparatus.

Abstract: An avionics system for retrofitting a GPS system to work with an existing autopilot by using signal switching and conditioning in an electronic flight display to accomplish the switching without the need for logic controlled relays in the GPS to autopilot interconnect wiring.

Abstract: A combined glassrun, greenhouse trim (10) for the window opening of an automotive vehicle comprising an extruded or co-extruded, polymeric glassrun (12) and a greenhouse trim (14). The greenhouse trim (14) is injection molded from a polymeric material against a surface of a flange portion (22) of the glassrun (12). The organic materials selected for the glassrun (12) and the greenhouse trim (14) are such that the greenhouse trim (14) is adhesively joined to the glassrun (12) during the injection molding of the greenhouse trim (14).

Abstract: The front bag (12) of a supply of bags (12) stored in a magazine (250) is removed by an unloading device (252) including four linkages (254, 256, 258, 260) which are pivoted to attach suction cups (264) thereto. The unloading device (252) inserts the bag (12) between nip rollers (52, 54) including spaced wheels (56, 58) which drive the bag (12) downward until the closed end (20) rests upon an adjustable stop (72). A tucking plate (90) moves from a retracted position to an extended position generally perpendicular to the bag (12) to drive the bag (12) into a slot (46) of a fixture (32), with the bag (12) having a U-shaped configuration around the tucking plate (90). The bag (12) is prevented from moving from the slot (46) with the tucking plate (90) as the tucking plate (90) moves from the extended position to the retracted position by a compression roller (208) pivotable by a cam (214) movable with the tucking plate (90) to sandwich the side edges of the bag (12).

Abstract: A radio receiver is effective to receive a radio frequency signal and derive therefrom a standard stereo composite signal comprising a sum of channels signal having components within a first band of frequencies in the audio range and a difference of channels signal having components within a second band of frequencies above the first band of frequencies. The radio receiver is provided with a low pass filter having a high frequency roll-off characteristic within the first frequency band and a substantially flat attenuated amplitude characteristic across the second frequency band. Linear mixer apparatus mixes filtered and unfiltered stereo composite signals in controlled relative proportion responsive to a control signal to produce a modified stereo composite signal for application to stereo decoder apparatus in order to simultaneously roll-off the high frequencies in each derived channel and to attenuate the difference of channels signal in degree controlled by the control signal.
