Abstract: ABSTRACT OF THE DISCLOSURE An improved circuit-interrupting device of the type which includes an arcing rod which is moved away from a stationary contact in response to an overcurrent through the device. The device includes a container of pressurized dielectric fluid having a port from which the fluid is directed at an elongating arc formed between the moving arcing rod and the stationary contact. The device also includes a diaphragm normally con-tacted by the arcing rod which normally closes the port and restrains arcing rod movement. The improvement includes a pattern of reduced thickness in the diaphragm about the point of contact between the diaphragm and the arcing rod. The pattern may be circular or star-shaped and may be produced by pressing, dieing, stamping, scoring, forming, etching, or coating. Depending on the specific construction of the device, the diaphragm either fuses or melts along the pattern or is ruptured or torn by arcing rod movement following an overcurrent through the device. The pattern ensures that a large opening is formed in the diaphragm to permit the escape from the container of sufficient dielectric fluid to ensure extinguishment of the arc.

Abstract: PBElder 6 ULTRAVIOLET LIGHT CONTROL II            ABSTRACT OF THE DISCLOSURE      An apparatus designed for monitoring the administering of ultraviolet therapy, particularly for portable use such as at the beach, has a control system adapted to monitor the instantaneous intensity of the ultraviolet light received by a subject being treated, wherein the instantaneous intensity is integrated by means of a rechargeable electrochemical cell to measure the total ultraviolet energy per unit area re-ceived by the subject during a given time.  The apparatus is so controlled that when the total energy received by the subject as measured by the apparatus reaches a predetermined preset value as determined by the discharged state of the electrochemical cell, a warning signal either visible or audible is given to the subject.  In an improved embodiment an electronic means is used to subtract the energy measured at one wavelength from the energy measured at other wavelengths, thereby providing a low cost filter means for selecting the desired wavelength  to be measured.

Abstract: TITLE:  FLOATING TOY                   ABSTRACT         A floating toy which is capable of propelling itself through a body of water has a body to which is attached a propelling member.  The propelling member is pivotally mounted to the body at its center and moves backward and forward in an oscillating motion. The member includes a ridge having an essentially triangular shape in cross section which is located at the leading edge of the member.  The ridge is able to cut through the water to move in a forward direction but meets with fluid resistance when moved in a rear-ward direction.  The resistance against the ridge propels the toy through the water.  The toy includes a head pivotally mounted to the body which is capable of moving in what can best be described as a nodding motion with respect to the body.  A float is located in the head such that when the toy floats on the surface of the body of water the head assumes the position wherein it is tilted back toward the back of the body and when the toy is removed from the body of water the head is capable of tilting toward the front of the toy.

Abstract: ABSTRACT OF THE DISCLOSURE Nowadays, solar energy is going to play a prominent part in our future.  Even solar radiation is not the only alternative among the renewable energy sources; others include wind, tridal and biomass (for example, firewood) energy.  Solar energy is, however, regarded as the most promising; its radiation has been helping us for many years, and, because of this, various systems of solar collectors are being used.  The most common ones are comprised of an assemblage of round pipes, interconnected by several prefabricated elbows.  In this invention, connected elbows are substituted by pairs of pipes which have, through-out their length, several apertures, separated by watertight bulkheads.  A series of other pipes having a flattened elliptical shape that increases the exposed area for catching solar radiation is adapted to the said apertures.  Such a new assemblage allows, on the one hand, the elimination of several elbows, and on the other hand, permits, with the flattened pipes, a larger area that can collect more solar radiation than the round pipes.

Abstract: ABSTRACT OF THE DISCLOSURE       Panel framework for supporting panel sheeting used in concrete forming structures, such as structures for supporting poured concrete in forming floors and walls.  The framework comprises a perimeter frame of spaced parallel siderails and endcap rails with a plurality of spaced rigid cross-members within the frame.  The endcap rails and cross-members are mechcanically secured to the siderails to provide for replacement of components of the framework.  The cross-members, as mechanically secured to the siderails, support the panel sheeting when affixed the the framework and used in forming concrete.  In assembling panels for forming walls, tie member panels may be used where the wall form panels are connectable to one another and to the tie member panels.  The panels are all of the same depth and have uninterrupted abutting edges, thus when interconnected, provide a substantially planar continuous frontwall face against which concrete may be poured without concrete leaking through the connections.  The rear edges of the panel rails also all lie in substantially the same plane.  Tie members span the opposing tie member panels and are arranged and so connected to the opposing wall arrangements to hold them in their predetermined spaced-apart relationship after concrete is poured between the wall arrangements.  Reinforcing members may be used with the tie members and clamped against the panel rear edges to reinforce the wall arrangements.

The bottom plate of C2 is electrically connected to the output of a voltage follower that has its input terminal connected to the second node.  A first switch means periodically connects the top plates of C1 and C2 to the first and second nodes at a prescribed rate.  When the first node is connected to a voltage source and the bottom plate of C1 is connected to either ground or the first node, the circuit simulates a source resistor across the nodes.  When the first node and bottom plate of C1 are connected to ground, the circuit simulates a grounded resistor.  In alternate embodiments, the capacitances of C1 and/or C3 may be zero valued for presenting an open circuit across the terminals thereof.  In yet another embodiment where C1 and C3 are zero valued and the first node is connected to ground, a second switch means essentially operating 180° out of phase with respect to the first switch means is located in the electrical connection of the bottom plate of C2 and the output terminal of the voltage follower for periodically connecting the bottom plate of C2 to the first node and the output of the voltage follower for causing the circuit to simulate a bilinear grounded resistor.  In an alternate embodiment of this structure, the first node is connected to the output of a voltage source for simulating a bilinear source resistor.

Abstract: ABSTRACT OF THE DISCLOSURE     A weapon firing system including weapon interrogation means is disclosed wherein a weapon control computer (8) provides a signal (at 27) for closing a normally open switch (16) and signals (at 29, 29A, 29B, 29N) for connecting one of a plurality of weapon select relays (18, 18A, 18B, 18N) to the switch.  During weapon interrogation, a low level interrogation signal (from 20) is applied through the closed switch and the one relay to a weapon igniter (12, 12A, 12B, 12N) connected to a corresponding weapon (2, 2A, 2B, 2N) to interrogate the availability of the weapon for firing.  The  igniter provides an impedance indicative of said availability which is sensed by a sensor (28) for  providing a signal (EL) which is applied to the computer for mission programming and display purposes. During weapon firing a fire signal (from 32) is applied through the closed switch and one of the relays  connected to the  switch to fire the weapon connected to the relay in a firing sequence depending on the  availability of the weapons.
