Abstract: A simple device for automatically filling a plurality of open containers, such as bottles, to permit a plurality of such containers to be sequentially filled, when connected to a constant source of liquid, without possibility of running over. A common header receiving the liquid has a plurality of depending traps, each connected thereto with an inlet tube which is shorter than the distance the traps outlet tube extends into the container, whereby the entrance of the liquid is automatically cut off when the liquid level in the container rises sufficiently to cover the lower end of the outlet tube and the hydrostatic pressure thereat equals that of the inlet tube.

Abstract: A portable rotary snow thrower is disclosed. The housing of the snow thrower is baffled to cause the snow to be thrown to one side for a particular direction of rotation of the rotor. The rotor may also be rotated in the opposite direction to throw the snow to the opposite side of the snow thrower through the same opening without repositioning of baffles or other mechanical elements.

Abstract: A heat-exchanging system having an upright water tube in a water tank with an open upper end and connected at each end to a surrounding tube of larger diameter which forms a spaced jacket therearound and a centrally arranged tube connected at its lower end to the discharge of a compressor of a refrigerating system and extending upwardly within the water tube and connected at its upper end with the space between the water tube and its surrounding tube. The latter has an outlet connected to the return inlet of the condenser and hence the compressor of the refrigerating system. The water tank has a hot water outlet at its upper end connected with the supply inlet of a conventional hot water heater, and a cold water outlet adjacent its lower end, the latter being connected to the inlet of the water tube and to a source of pressurized cold water.

Abstract: The battery system includes a metallic anode, a cathode/electrolyte comprising a liquid inorganic solvent containing a mixture of an interhalogen having a discharge potential higher than the solvent and a soluble salt of the anode metal, and a high-surface-area cathode current collector means coupled with the cathode/electrolyte.

Abstract: A readily adjustable machine which continuously produces corrugated flexible metal tubing from very light gauge metal and of various diameters. A warping ring receives therewithin a longitudinally corrugated narrow strip of formable metal of light gauge and warps the same helically to produce convolutions by means of a helical warping surface which extends into one of the longitudinal corrugations. The size of the tube produced can be varied by merely substituting a warping ring of a different size. A uniquely shaped pair of die-forming rollers have lock-seam forming surfaces which are adjustable relative to each other to provide variation in the degree to which the seam will permit and withstand axial torque. The lock seam is constructed to be symmetrical about the neutral axis of the corrugation and about the slope line of the common corrugation leg of adjacent convolutions which it constitutes.

Abstract: An improved body implantable electrical stimulator assembly of the type having interconnected electrical components housed within a preformed enclosure. A cup is provided in which the components are finally assembled, the cup being configured to fit within the enclosure. Preferably, the enclosure is formed of a plurality of members at least one of which has a main wall and a side wall joined at a radius. The cup is similarly formed of a main wall and a side wall, the main wall being generally coextensive with at least a major portion of the enclosure member main wall. The cup engages the enclosure in a manner such that its movement within the enclosure is limited. Movement of the components within the cup is restrained.

Abstract: An improved photographic printer of the type wherein photosensitive photographic material is automatically advanced through an exposure area and is marked intermediate adjacent exposures to facilitate the separation or cutting of the different exposures. The improvement consists of a marking system having elements movable in and out of the exposure area to mark the photographic material while it is in the exposure area but without obstructing the photographic material while it is being exposed. In a preferred embodiment, the marking system includes a punch carried by a rotatable eccentric member, the punch being carried in and out of the exposure area on rotation of the eccentric member. The eccentric member is biased to maintain the punch out of the exposure area and is provided with a camming surface engagable by a reciprocal member, cooperation between the reciprocal member and camming surface causing rotation of the eccentric member.

Abstract: The invention relates to a simplified wire snap formed of a bent piece of wire made of a high tensile steel material. The wire snap is formed by bending a length of wire at its extremities so that the bends face back toward one another and on a central body of the wire therebetween. The extremities of the bent wire have hooks therein and the hooks are directed in opposite directions with offsetting or angular bends therein to permit the wires to be readily bent and fit around the main body portion to secure to the same. The hook extremity of one bend portion overlies or extends beyond the hook extremity of the opposite bent portion to significantly increase the tensile strength of the wire snap.

Abstract: One-piece type-carrier elements made by etching.

Abstract: This invention relates to automatic dual mode battery charging circuit which includes rectifying means and an adjustable voltage rectifier energized by the rectifying means and providing an output to a battery to be charged. The circuit includes a voltage controller connected to the voltage regulator means to set the level of voltage output from the voltage regulator and hence the charging current to the battery. The voltage regulating means provides two modes of operation, namely, a fast charge and a float mode of operation. A current detector connecting in series circuit with the voltage regulator and the battery provides a means for detecting current flow through the battery and controls the operation of the voltage controller, to change the output of the voltage regulating means between the two modes of operation.

A dual state device responds to the charge level of the energy storage device and changes state in response to predetermined changes in the energy storage device charge level. The charging rate is alterable to alter the duration of the driving pulse.

Abstract: The invention relates to an apparatus for preventing or limiting water damage caused by leakage from pipes or appliances in which a sensing element in the form of a pair of conductors having current applied thereto is positioned in an area to sense accumulation of water from leakage. The sensing element is connected to a resettable relay to operate the same when current flows between conductors of the sensing element. The relay is bi-stable and resettable and operates to disconnect the sensing element after initial conduction and to further apply heat through the heating element to a thermostatic valve to operate the thermostatic valve in a direction to close off water flow to piping or apparatus in which leakage occurs.

Abstract: A heart valve having a base with a passage and a free-floating pivoting disc for controlling the flow of blood through the passage. Inwardly directed proximal and distal pivots control the pivoting movement of the disc. The pivots are offset from the diameter of the disc so that the disc pivots between its open and closed positions between its center and an outer peripheral edge of the disc. The disc is held in free-floating assembled relation with the pivots and base with a curved retaining rod having a curved end projected through a central hole in the disc. In one form of the valve a permanent magnet in the disc assists the closing of the disc in response to a drop in the pressure of blood moving through the valve passage. A suture collar surrounds and is mounted on the outer portions of the base. A low friction sleeve interposed between the base and the collar permits rotation of the valve relative to the suturing collar after the collar has been attached to the heart tissue.
