Abstract: Containers for use in a dispersal with the containers enabling a fluid mixing stream to separately and controllably disperse two different water treatment materials into a water treatment system.

Abstract: Nestable canisters for use in a dispersal valve that normally holds only a single canister with the nestable canisters suitable for replacing single canisters to enable a fluid mixing stream to be bifurcated and simultaneously but separately treat the water with different materials. The fluid mixing stream which normally flows through the set of ports that are used for dispensing only one solid chemical into the liquid stream flowing through the dispersal valve is bifurcated to provide for both dispersant type bacteria killing as well as in situ bacteria killing. In addition the nestable canisters are provided with an improved bactericide and algaecide for killing algae in the water and absorbing acids that might be generated by use of chlorine in the dispersal valve.

Abstract: A soil aeration tine having a nose or apex end for soil penetration with a set of soil fracture faces carried thereon to fracture a portion of the soil in engagement with the soil aeration tine and a cutting tube positioned on the soil aeration tine with the soil cutting tube cutting a soil plug free of a further portion of the soil with the soil penetration tine having a lateral face for scooping out soil as the soil aeration tine is removed from the soil.

Abstract: An apparatus and method for pressure casting a battery part wherein the state of molten lead is monitored so that when the molten lead enters a liquid-to-solid transformation stage, the volume of the mold available for the lead to solidify therein is quickly reduced through a volume contraction step to thereby cause the molten lead to flow into the remaining volume at the same time one maintains pressure on the molten lead. As the molten lead solidifies under the reduced volume and high pressure it produces a battery part that is substantially free of both tears and cracks. In an alternate method, the lead is allowed to solidify and at least a portion of the lead is mechanically deformed through a volume contraction step to cause cracks or tears in the battery part to be eliminated thereby providing a battery part free of cracks or tears.

Abstract: A hollow tap having an axially outward extending cutting tooth so that when the cutting tooth is brought into rotational pressure engagement with a resilient tubing the cutting tooth cuts a hole partially through the resilient tubing leaving a coupon hingedly but securely attached to the resilient tubing to maintain the coupon in an out-of-the-way condition within the resilient tubing. Continued rotation of the tap within a saddle brings a sealing surface on the cutting tube into fluid tight seal with the resilient tubing to provide a branch outlet to the resilient tubing though the tap.

Abstract: The present invention is directed to a one piece sinker reversibly attachable to a fishing line. The sinker is a streamlined, truncated cone shape having a line accepting passage along the center line thereof. The sinker includes line centering surfaces to prevent line twist as the sinker is drawn though water, and a elongated thumb slot for inserting a tool having a length longer than the sinker to allow a user to manually opening the sinker. Also disclosed is a method of making the sinker employing a unique core blade punch for forming the line accepting passage with the sinker jaws having discontinuous but mateable line engaging surfaces.

Abstract: A method of connecting pipes in a fluid-tight end-to-end relationship and a universal pipe coupler that maintain the pipe ends proximate one another as the coupler simultaneously aligns the ends of the pipes and draws the pipes into a fluid tight sealing relationship with the universal pipe coupler colorable with frictional engaging collars or fixedly engaging collars to hold the pipe in position.

Abstract: A water purification device, method and system with the water purification device having a container for holding a water purification material therein with the water purification device including a shroud extending in a direction generally normal to a flow of debris laden water with the shroud inhibiting direct flow of debris into a water inlet in the water purification device by directing water and debris over the shroud and around the water purification device while a portion of the water can be directed laterally into the water purification material within the water purification device to thereby purify the water that flows over the water purification materials with the water purification device including multiple spaced and positioned water inlets so that the likelihood of the water inlet being completely obstructed is remote.

Abstract: A cord holder having a body member with cord retaining regions on each end with the body member having a temporally securable closure member on each end to allow quick passage of a cord into the cord retaining regions with the securable closure members securable to each other to hold the cord on the body member and the body member having an integral flexible member for securing and end of a cord to be wound thereon as one begins to wind the cord around the cord holder.

Abstract: There is an information registration apparatus for registering patrons entering a club or other commercial use. The apparatus comprises a housing (1) with a top panel (3) and sign-in window (4). A form (14A) is displayed in the window (4) for handwritten entry of information by a patron. The information is then photographed from the underside by means of a camera (9) and image reversing reflective mirror (10) and stored or transmitted to a viewing station.

Abstract: A dispenser apparatus for cantileverly mounting in an off-line condition in an axially component of a water system with the dispenser apparatus carrying a water treatment composition therein that can be released into a water system with one embodiment of the dispenser apparatus including a pair of replaceable containers for holding a water treatment composition with the containers serially located so that the water flowing into one container flows into the second container with the second container removable from the first container so that the second water treatment composition can be replenished without having to replenish the water treatment composition in the first container.

Abstract: A boat seat is mounted on two sets of slidably engaged members for slidably adjusting the location of the boat seat front and back with a locking mechanism for holding the seat at its adjusted location comprising a locking pin for engaging detent holes controlled by a lever arm extending out the front of and below the boat seat.

Abstract: A coaxial drop cable safety device is used for cable television, data and telephony applications. The device is used on buried drop cable where 60 Hz powering voltages applied to the drop cable exceed low voltage safety limits and where the drop cable is buried at depths which is less than the minimum required to meet electrical safety codes. Tap end and premise end units are connected to the drop cable. The tap end unit applies a DC voltage to the center conductor of the drop cable. A monitoring circuit in the tap end unit monitors the DC current in the center conductor. The tap unit will immediately remove the powering voltage in the event of either an open or faulted condition on the center conductor along the entire length of the drop cable. Additionally, while providing fault protection for the low frequency powering circuit due to tampering or damage to the cable, the fault monitoring circuit allows the high frequency television, data and telephony signals to pass with little or no impediment.

Abstract: A method of generation of smoothly shaped, non-circular, curves by formation of multiple circular arcs. In the method, one draws a first circular arc which passes through two points and is tangent to a first line extending from a first point in the indicated direction. Next, one repeats the process by drawing a second circular arc which passes through one of the aforementioned two points and a third point and is tangent to an extending line. By utilizing of a common point for each of the two circular arcs one can generate a smooth, non-circular, curve from the end blending of the two circular arcs. By moving or deleting points, or by adding points, or by changing the defined directed tangent line, or by defining a directed tangent line at a different point, one can reconfigure the curve into the desired final curve. Several curves can be combined to generate a desired figure.
