Abstract: This invention relates to a packaging container, and a preform therefor, which finds particular application in the packaging and protection of relatively soft products, such as fresh produce. The container comprises a pair of end web plates (12) formed with peripherally extending projections (20). A cover sheet (10) is wrapped about the peripheries of the web plates (12). The cover sheet (10) is folded along fold lines (16) and is formed with slots (18) through which the projections (20) on the web plates (12) may extend when the cover sheet (10) is wrapped about the web plates (12). The web plates (12) are formed with locking slots (26) into which the longitudinal edges (28) of the cover sheet (10) may be clipped to retain the cover sheet (10) in position.

Abstract: An aquarium heating system utilizes a conductive coating on an aquarium glass viewing window to heat the aquarium water. The conductive coating is transparent and is disposed on the surface of at least one viewing window. A voltage is supplied to the conductive coating under control of a power supply which operates to maintain the water at a constant temperature.

Abstract: A knock-down box produced by injection mold process comprises: a multiplicity of sides and a bottom, a multiplicity of male trapezoidal segments along an edge of the side, an alternating sequence of multiplicity of rectangular tracks and a multiplicity of female trapezoidal segments contiguous and in-line with each other parallel to an edge of the bottom, a dimensioning of the male trapezoidal segments to permit insertion into the rectangular tracks alternately in-line with the female trapezoidal sections, the dimensioning designed to assure a friction slip of the male trapezoid segments along the rectangular track into a captive engagement in female trapezoidal segment assuring a rigid construction of the bottom.

Abstract: A device is described particularly suited for the bathing of pet cats and small dogs. Research has indicated that a cat bath which is made of transparent material and so dimensioned and designed to permit the cat to grasp an upper section of said bath with its forepaws tends to pacify the animal. In addition, the bath has variable size patterns which serves as a aperture through which the cat can put its head but not its shoulders. The bathing container has an agitator and a ring spray which keeps the water in motion about the animal. Research has indicated that the width and breadth of said cat bath must be less than the length of the average cat and the height of the container approximately the length of an average cat. When the animal is placed into the container and liquid admitted, the animal stands on its rear paws with its forepaws grasping the upper section of the bath and its head out of the aperture.

Abstract: A bicycle which sounds an audible signal on motion of the bicycle is described. The alarm system is totally self contained and appropriately attached to the frame of the bicycle. It contains critical delay circuits which gives the bicycle rider the opportunity to arm and disarm the alarm by a key switch without tripping the audible alarm. Additional circuitry prevents the audible alarm from remaining in an on state indefinitely after the alarm is tripped, thereby conserving battery power. Said bicycle includes a motion detection switching means, alarm timer means, limit means and oscillator means all conveniently contained in a compact package. Recent progress in the development of energy efficient audible alarms assures a loud signal on the impermissible motion of the bike.

Abstract: A spear gun assembly for propelling a sharpened spear in an underwater hunting environment. The assembly includes a holding bar rigidly attached to the gun which engages a hole in the spear. A trigger assembly is actuatable to pivot a lifter for lifting the spear from the holding bar, thereby releasing the spear from the gun. The trigger assembly is provided with a safety mechanism for preventing the lifter from pivoting and a lanyard which is disengaged as the trigger is actuated.

Abstract: An adjustable sheet for a windsurfing harness on a boom of an articulated mast of a windsurfing board comprising an elastic element, one end of which is secured to the boom; a sheet which is attached to the other end of the elastic element; a dual-action clamp through which the sheet is routed; and a quick release element to disengage the dual action clamp such that the sheet is disengaged from the dual-action clamp and the sheet may be elongated or shortened.

Abstract: A baffle for filtering cigarette smoke is described. The baffle is inserted into commonly available cigarette holders. The cleansing and filtering action of the baffle system is augmented by the throttling of the smoke in successive chambers which were created by the walls of the baffle and the interior of the cigarette holder. The successive chambers are interconnected by orifices.

Abstract: A Beach Mat with built-in Adjustable Sun Shade is described. The head of the mat contains elastic stays. These elastic stays permit the head of the mat to be shaped into an arc with the help of strings. Said arc becomes a sun shade. On relief of the tension of the stays by releasing the strings, the mat may be rolled into a small cylinder for transportation and storage.

Abstract: A buckle is described which is to be attached to the lineman's safety belt, the buckle has a multiplicity of short and long rows claws on the front side of a plate and these claws penetrate into the wooden pole the lineman is climbing, on the backside of the plate, there is a lock for keeping, locking, and pining the buckle to the safety belt, the multiplicity of rows of claws are designed so as to drive the claws into the pole and pivoting the buckle around some of the claws if the lineman experiences a fall.

Abstract: The invention describes a method for determining the assay of gold alloy. It utilizes a dynamic electrochemical process. The specimen gold is wetted by a described electrolyte, and a small current anodizes the surface of the specimen for a metered period of time. A potential sensing device is then applied to the charged surface, and a potential decay is observed. The potential decay information is compared with empirical data and by interpolating said potential decay with the empirical data a determination of the karat quality of the gold alloy may be determined. This same method may be used for other precious metals, employing different electrolytes, empirical standards, and potentiometers.

Abstract: The principal of total internal reflection is utilized in sounding an alarm in a medical fluid infusion system when a downstream blockage occurs. A miniature prism is mounted in a cavity in a rigid exterior tube. The infusing fluid flows in a plastic tubing along the central channel of the rigid tube. The plastic tubing in the interior of this exterior rigid tube is diametrically expansive with an unpressurized outside diameter which is less than the inside diameter of said rigid exterior tube. A light source and light detector is positioned adjacent to the equilateral planes of the prism mounted in the rigid tube.

Abstract: A device is described which is used to ground power distribution subterranean cables. A grounding module may be positioned over a connector to the power cables. A remote trigger then fires a probe through an insulating cap on the connector to make a ground circuit from the cable through the connector and probe to a grounding clamp.

Abstract: A spacer system for concrete forms is described for composite concrete constructions walls which permits the forming materials to remain intact with the concrete poured into the forms. The forming materials then become the exterior surfaces of the mold, saving considerable time and money usually expended in finishing or molding a design into the exterior surfaces.

Abstract: A chamber of a peristaltic pump is described wherein a segment of the stator is removed so that said chamber containing the rotor and resilient tube may be stored with the resilient tube not pinched by the eccentric rotor. When the chamber is to be used, a cap is snapped over the chamber which completes the missing segment of the stator and the rotor is engaged to the motor shaft. When the rotor turns in the stator with all segments snapped together, liquid is conducted from inlet to outlet ports.
