Abstract: A multi-function sensor is disclosed for measuring the conditions within a container, such as fluid level, turbidity, temperature and pressure. The sensor incorporates a fluid level sensor module, a turbidity sensor module, a temperature sensor module and a pressure sensor module. The fluid level sensor module utilizes a plurality of thermocouple junctions grouped in pairs with the pairs being spaced along a line extending generally in the direction in which the liquid level may vary. The thermocouple junctions are connected in series and produce a signal indicative of the level along the sensor. Turbidity, temperature, and pressure sensor modules may also be incorporated in the multi-function sensor. Alternatively, a fluid flow rate sensor module may be included in place of the liquid level sensor module.

Abstract: A high temperature PTC device comprising a polymeric conductive composition that includes nylon-11 and a carbon-based particulate conductive filler has a switching temperature greater than 150.degree. C., preferably between about 160.degree. C. and 200.degree. C. The composition demonstrates a high PTC effect (at least 10.sup.3, and more typically 10.sup.4 to 10.sup.5 or greater) and a resistivity at 25.degree. C. of 100 .OMEGA.cm or less, preferably 10 .OMEGA.cm or less. High temperature PTC devices that comprise nylon-11 or nylon-12 compositions and that are manufactured by extrusion/lamination demonstrate good thermal and electrical stability compared with those manufactured by compression molding and do not require composition crosslinking for stability, although crosslinking may be used to further improve stability. The use of a high temperature solder for attaching electrical terminals to the device improves the PTC properties of the device.

Abstract: A barcode module for an automated data storage libary is described. More particularly, a barcode module capable of being manipulated by a picker and easily retrofitted to existing data storage libraries is described. The barcode module may be equipped with a network interface capable of receiving high-level commands over a control network from a central control unit and converting the high-level commands into low-level commands used to control the barcode module.

Abstract: A disc golf target includes a center post, a chain rack supported by the post, and a lower basket supported by the post opposite the chain rack. The chain rack has a hub mounted to the post, a plurality of spokes radially extending from the hub for supporting the circumference of the chain rack in concentric alignment with the hub, and a plurality of attachment points concentrically disposed between the hub and the circumference of the chain rack. A plurality of outer chains having first and second ends has the first end supported by the chain rack and the second end attached to an outer chain ring disposed about the post near the basket. A plurality of inner chains having first and second ends has each end supported by a respective attachment point wherein the inner chains vertically hand downward from the attachment points in an overlapping fashion to define an inner envelope for catching a disc.

Abstract: A flying disc, such as used for catching and/or throwing, constructed in a single piece structure integrally molded from flexible plastic material having a central flight plate section, an outer rim, and a shoulder section connecting the central flight plate section to the outer rim, the top surface of the outer rim having a raised ridge which provides a gripping surface and which gives the appearance of a rear spoiler which is believed to act as a rear control or deflection surface on the trailing edge of the disc.

Abstract: An entrapment assembly suitable for use as a "hole" in, e.g., a flying disc golf game, is disclosed. The assembly consists of a top portion operatively connected to a nest bottom portion, wherein at least one deflection member is operatively connected to said top portion and descends therefrom to form a "caged" target area for a flying disc or other object. In a preferred embodiment of the assembly, the caged target area is operatively connected to a pedestal and the deflection member or members are a series of tubular shaped impact absorbing members, curved slightly inward, pivotally attached to said top portion and descending into the nest.

Abstract: A method for refinishing rigid data storage discs for recoating including the steps of removing a magnetically alterable coating and its sub-interfacing material from rigid data storage discs to expose disc substrates, inspecting the substrate for surface discontinuities, measuring the thickness and flatness of the substrates, resurfacing the surfaces of the substrates to remove surface unevenness and surface discontinuities, polishing the surfaces of the substrates to produce a visually mar-free flat substrates, and rinsing and drying the substrate before recoating.

Abstract: The driving member of this torsional impulse damper is a disc-like plate, coaxially securable at its peripheral portions to an engine flywheel. The driven member comprises two carrier elements, at opposite sides of the driving member, rigidly connected at bosses that are spaced from the rotational axis and extend through larger holes in the driving member. Friction surfaces on inner faces of the carrier elements engage the opposite flat faces of the driving member. Cooperating with the friction surfaces to maintain the driving and driven members coaxial is a coaxial trunnion on one carrier element projecting into a bearing fitted in a central hole in the driving member. The carrier elements cooperate to enclose springs that react between the driving and driven members. A universal joint at one end of a drive shaft is directly connected to one of the carrier elements.

Abstract: Methods and apparatus for making picture records whereby records of a high quality may be mass produced at a faster rate. In accordance with the method, a thin layer of plastic is first laminated over sheets containing the pictures desired. The laminated pictures are then cut from the sheets, preferably to have a diameter slightly smaller than the diameter of the desired finished record. Thereafter, the laminated pictures are placed in the record press two at a time, each with the picutre and plastic lamination thereover facing the adjacent die half. A biscuit, or alternatively a sheet of appropriate size is placed therebetween and the die is closed to press the record, with trimming, etc. proceeding in accordance with prior art techniques. Apparatus for practicing the method on an automatic record press is disclosed, though alternatively the method may be practiced to advantage on manual presses also.

Abstract: A motor overload protector or the like is disclosed in which a bimetal snap disc is centrally supported by a stud which is press fitted into a bore within the body. The stud is knurled to provide axially extending teeth having a root diameter at least substantially equal to the diameter of the body stud receiving bore prior to the insertion of the stud so that sufficient friction is provided to maintain the stud in the calibrated position. Additional locking is provided where necessary by forming the stud with annular ribs which interlock with a potting material applied after assembly of the stud within the body. The device is calibrated by maintaining the disc at the desired operating temperature as the stud is pressed into the body stud receiving bore until the disc operates.
