Abstract: A method for providing a continuous binary coded output measurement of an unknown input frequency or pulse rate. The unknown pulse rate is compared against a first known frequency and an output is obtained in binary coded form which is functionally related to the approximate ratio of the unknown pulse rate to the known pulse rate. A second unknown pulse rate equal to the difference between the unknown pulse rate and the ratio times the known pulse rate is generated. The unknown input pulse rate or the second unknown pulse rate is then transferred to a second stage when the ratio is less than one or greater than one respectively. A series of such comparisons are made to obtain an approximate value for the unknown pulse rate to a predetermined resolution.Apparatus is provided for receiving and continuously providing an output measurement for an unknown input frequency. A clock circuit provides a plurality of known frequencies having a predetermined interrelationship.

Abstract: A deformation detector for use with IV needles or catheters inserted into the human body is disclosed. Swelling and deformation attributal to other sources is also detectable. The apparatus in particular has a preferred embodiment which comprises a generally rectangular body enclosing an air chamber. The chamber is rectangular and is open on one face thereof, a thin diaphragm is attached. The body has an encircling lip which is joined by a suitable adhesive to the body adjacent to a IV needle or catheter. In the event of swelling as a result of improper operation of the injection which swelling, while hardly visible to the eye, is detected by protrusion of the body into the chamber to increase air pressure in the chamber. Swelling or edema from other sources is similarly detectable. The swelling decreases the internal volume of the chamber and thereby forms a pneumatic signal supplied through a tubing to a transducer or recording device. This is used to form a signal of swelling or edema.

Abstract: In one exemplary embodiment, a construction clip for rigidly interconnecting and uniformly spacing a pair of ceiling inverted-tee support members defining an air conditioning air-slot through the ceiling is provided. Further, the clip provides support for the air conditioning ducts which carry air from the main air conditioning ducts to the air-slot. The clip, which is preferably formed of a high grade spring steel, includes an elongated body member having at each extremity a pair of legs extending normally upward from the body member and into a generally U-shaped configuration for securely gripping the vertical portion of the inverted-tee support members. The extremities of each leg are inwardly bent to form clasping hook ends for tightly gripping the tee member vertical portion in a sliding relation. Each pair of legs defines a slot therebetween which extends from the body member to the extremities of the legs to enable the clip to be positioned over intersecting tee members.

Abstract: A method of providing a protective coating for a metallic object required to retain lubricity notwithstanding prolonged submersion in a deleterious environment such as salt water. The object is first plated with a preselected corrosion-resistant metal. Next, the plating on the object is phosphatized or otherwise processed to improve its bonding capability, and then the object is coated with a fluorocarbon polymer to impart lubricity to the object sought to be protected.In an alternative form of the process, wherein the object is electroplated or otherwise coated with a metal incapable of being phosphatized, the bonding capability of the electroplating is improved by providing it with a matte surface, as by sandblasting or the like, in preparation for the fluorocarbon polymer outer coating.

Abstract: A light fixture support is provided comprising a support bar having slots at the extremities which cooperate with inverted "T" members forming the framework for a conventional suspended ceiling to adjustably locate and secure a light fixture within the framework. The slot configuration defined by the light fixture support permits the enlarged extremity of the upstanding portion of the "T" member to be rotated for insertion within the slot, returned to a vertical position, and retained within the slot. If desired, an adjustable support may be provided for accommodating a variety of "T" member spacings or for compact packaging with a light fixture.

Abstract: A rotary-type lawn mower is provided with cutting means comprised of a rotatable disc-like member having a plurality of flexible non-metallic cords projecting radially from its perimeter. The disc-like member is rotated within the cutting plane by a suitable power source such as a conventional gasoline-driven engine, and at a velocity such that the projecting cords function to sever the grass in a substantially conventional manner. The cords are therefore of a length and diameter which are functionally related to effective cutting and are mounted within the disc-like member in brackets formed to support the cords against vertical as well as lateral deflection resulting from contact with the grass sought to be cut.

Abstract: A porous pipe primarily of rubber and synthetic rubber reclaimed from rubber tires, ground to a relatively small granular size, with metal removed; such as, for example, would pass through a 30-mesh screen, process-mixed through a pipe extruder, with a much smaller binder mix of primarily polyethylene, along with vinyl, ABS binder, and a trace of attaclay. The resulting product is useful as a subsurface irrigation buried pipe, having high structural integrity effectively resisting soil-loading pipe collapse, and it even resists collapse from moderately large rocks in the soil, and yet has a high degree of flexibility along its length. A pipe is provided with cross sectional area of pipe wall more than twice the cross sectional area of the pipe opening.
