Abstract: A support for positioning a milker unit beneath a cow has a shaft which is vertically movably mounted on a base. An arm on the shaft supports a milker unit beneath a cow. Air pressure is applied to the shaft to hold the shaft and arm at a desired vertical position. A control automatically adjusts the vertical position of the support so that when the milker unit is attached to a cow's teats the weight of the milker unit is applied solely to the cow's teats. The control includes a pair of valves each connected to a supply of air under pressure. A first of the valves has an open position in which the amount of pressure applied to the support decreases and the support is permitted to lower. A second of the valves has an open position in which air from the supply moves the first valve from a normally closed position to the open position thereof. The control has a lever mounted on the arm for moving the second valve to the open position thereof when the milker unit applies force to the lever.

Abstract: An improvement in a starter of the type having a housing to be attached to an internal combustion engine and structure on the housing for rotating a crank shaft on the internal combustion engine to which the housing is attached. The improvement resides in structure for intermittently operating a decompression mechanism on the internal combustion engine to which the housing is attached as an incident of the crank shaft rotating structure being operated.

Abstract: An ultrasound teat dip comprises a dip cup having a well adapted to receive a supply of a germicide and an upper opening for receiving a teat to be dipped in the germicide, in use. A sonic transducer is operatively coupled to the well to sonically vibrate the well to produce cavitation in the germicide supply. A storage vessel defines a reservoir for storing a supply of germicide. The storage vessel is secured to the dip cup. A flow tube transfers germicide stored in the reservoir to the well to refill the dip cup with germicide.

A plurality of support plates are fixed to the cable at predetermined spaced locations therealong. At least one riser pipe string extends between the wellhead and the platform and includes a plurality of riser pipes engaged end-to-end. In one embodiment of the invention, each riser pipe includes a lower bell-shaped end and an upper spigot-shaped end inserted into the bell-shaped end of the immediately adjacent riser pipe thereabove. The lower bell-shaped end of each riser pipe rests by gravity on and is supported by one of the support plates. In another embodiment of the invention, each riser pipe includes an upper bell-shaped end and a lower spigot-shaped end inserted into the bell-shaped end of the immediately adjacent riser pipe therebelow.

Abstract: Smearing of indicia (30,36) or deterioration of a label may be eliminated in a label form that provides protection for the imaging (30,36) in a construction that includes a sheet of transparent face stock (12), a layer of transparent pressure sensitive adhesive (14) on one side of the stock sheet (12) and a sheet of transparent release liner (10) releasably adhered to the one side of the face stock sheet (12) by the adhesive (14). A die cut (18) is located in the release liner sheet (10) and defines a first removable frame section (20) and a second label defining section (22). The first section (20) surrounds the second section (22) so that when removed, a pattern of the adhesive (14) will be exposed. Reverse image printing (30) is disposed on the release liner second section (22).

Abstract: A binding line having selectable pin spacing on a gathering chain includes a gathering section including the gathering chain having a plurality of spaced pusher pins for transporting gathered signatures seriatim therealong to a signature exit end. A stitcher section includes a stitcher chain having a plurality of spaced pusher pins for transporting signatures seriatim therealong from a signature entry end. A drive system provides for driving the gathering chain synchronously with the stitcher chain so that both the gathering section and stitcher section operate at a constant signature feed rate. The gathering chain pins are spaced apart a first select distance and the stitcher chain pins are spaced apart a second select distance, different from the first select distance. The drive system drives the gathering chain at a different velocity from the stitcher chain to provide the constant signature feed rate.

Abstract: A composite filament reinforced clevis includes a pair of apertured ends and a central hub area with a pair of clevis arms extending between the hub area and the apertured ends. The clevis is fabricated by winding reinforcing filaments around a pair of end mandrels and toward the central hub area. The end mandrels and the filaments wound thereon are rotated relative to the central hub area to a collinear orientation. The reinforcing filaments are cured with a bonding matrix while in the rotated orientation.

Abstract: A carton glue monitoring system includes a conveyor moving a plurality of cartons in a first direction. An encoder provides pulses at a rate proportional to conveyor line speed. A glue applicator applies a glue strip having a fluorescent material added thereto to the cartons on the conveyor. A glue check station includes a UV source for illuminating the fluorescent material in the glue and a UV sensor for sensing the fluorescent material. The glue station further includes a glue skip detector and an excess glue detector for generating a glue flag and for holding the glue flag until the carton exits the glue station. A glue shift register includes Y registers and is connected to the UV sensor and the encoder for shifting the glue flag in the Y registers. Y is proportional to the encoder rate and a distance between the rejection marking device and the glue station exit minus the carton length.

Abstract: A polymer composite contains colorant molecules dispersed therein. The colorant molecules can be dispersed in the polymer or bound to the polymer molecules. When the polymer is a polyamide, the polyamide is in a noncrystalline state due to the inhibition of crystallization imparted by the size and shape of the colorant molecules because the colorant is separated on a molecular level. A high colorant availability is obtained. A method of producing the polymer composite includes the steps of forming a metastable polymer resin layer, applying a film of colorant to the layer, stabilizing the layer, dissolving the stable layer in a solvent, aspirating the solution to remove impurities and aggregates and then removing the solvent. A polymer composition can be produced by mixing the polymer composite with a polymer.

Abstract: A growth medium that is capable of supporting plant life includes a water retention component and soil. The water retention component can be a water retaining grain polish, bran or cut, short mineral wool fibers. A method of making the growth medium includes the steps of providing the water retention component and the soil, applying the water retention component to the soil and admixing the water retention component into the soil to distribute the water retention material within the soil to improve the water retaining capabilities of the soil. Vegetation matter, especially when mixed with animal excrement, will also contribute to the water retention property of the growth medium in addition to its slow release nutrient.
