Abstract: A burglar-proof protector for locks mounted on doors having a cover enshrouding the lock and secured to the door with an opening in the center of the cover for receiving a key to permit actuation of the lock. A plate member is secured to the jamb of the doorway adjacent the cover to prevent manipulation of a tool between the cover and the jamb whereby the jamb may be damaged and the bolt retracted without the use of a key.

Abstract: A burglar-proof guard for electric bulbs positioned in a socket having a peripheral shoulder consisting of a pivoted frame member mounted on the top portion of the bulb and a second pivoted frame member extending about the socket with three rods and a threaded bolt extending therebetween. Each of the pivoted frame members consist of a pair of semi-circular members with bores at the ends and at a mid-portion and the rods and bolt extending through the bores. The bolt is provided with a nut and a bore for receiving a lock preventing the removal of the guard from the light bulb without a key for the lock.

Abstract: An ultraviolet water purifier having a plurality of ultraviolet lamps mounted in a cover extending over the purifier and above the water in the purifier with a parabolic reflector directing the rays of the lamps toward the body of water. The purifier is provided with a water inlet and a baffle adjacent thereto having an opening at its base to compel the water entering the purifier to flow directly downwardly and then to flow through a plurality of filter. Air bubbles are trapped by a second baffle extending downwardly from the cover to below the water level.

Abstract: A dynamically balanced apparatus for water borne instruments such as current direction and velocity meters having a stand off support rotatably secured to a cable whose lower end is anchored and its upper end attached to a buoy. A swivelled connector extends from the free end of the stand off to the mid-portion of an elongated cylindrical housing, the latter being rotatably mounted to the connector and weighted along its lower portion whereby the housing assumes a normal predetermined horizontal position at all times. A duct symmetrically disposed at each end of the housing and a water velocity and direction member mounted in each of the ducts. A pair of rudders extending rearwardly of the connector whereby the housing is constantly maintained in a direction facing the current and the ducts in a horizontal position for recording the direction and velocity of the current accurately.

Abstract: Facing structures for buildings simulating brick, stone, shingle and the like consisting of rectangular shaped panels of identical construction that interlock, overlap and abut with each other, each panel having a flange extending along its top and a first side edge that terminates in a wedge shaped edge portion that is received by a mating slot portion formed along the bottom and other side edge. The top and first side flanges are provided with openings for receiving rails that are overlapped by the edges of the adjoining panels along the slotted portions; the portion of these flanges along the tops of the panels not overlapped by the adjoining panels form a continuous mortar line while the portion of the flanges along the sides of the panels not overlapped form interrupted mortar lines.

Abstract: A roller assembly for sliding doors having a pair of housings one within the other with a coil spring yieldingly urging the inner housing in a direction away from the outer housing, the inner housing supporting a wheel that extends beyond the housing. Tabs are struck on the side walls of the outer housing limiting the outer movement of the inner housing and for the securing of the assembly in a sliding door frame.

Abstract: A precision cut-off weighing apparatus having a balance type weighing device on which a desired weight is placed on one side and a bag to be filled with a fluid such as blood on the other. A magnet is mounted on the arm of the balance on which the bag is placed and a reed switch in a circuit mounted in proximity of the magnet to be influenced to close the circuit when the arm swings to the balanced position and bag has been filled to substantially the exact weight desired. The circuit is connected to a lever mounted on a support through which a tube extends to the bag whereby when the reed switch has been actuated, the lever swings to compress the tube and thereby prevent any further flow of fluid to the bag.

Abstract: A disposable mouth to mouth resuscitation device consisting of a pair of tubular members cemented together in end to end relation with a pair of valve discs in contact with each other interposed therebetween; one of the valve discs being rigid and the other flexible. Upon the person performing the resuscitation breathes into the tubular member having the rigid valve disc adjacent thereto, the flexible valve disc is made to flex away from the rigid valve disc and permit the air to pass through the second tubular member and into the person's mouth being resuscitated. Each exhalation of air and any vomit emitted by the person being resuscitated cause the flexible valve disc to seal against the rigid valve disc and be discharged to the atmosphere through openings formed in the side of the second tubular member.

Abstract: A water current force measuring apparatus consisting of a pliable rope or line suspended in the water with its lower end anchored to the bottom while the length of the line is subjected to the forces of the current. The upper end of the line is secured to a tensiometer or strain gauge, which in turn is connected to a float or a series of interconnected buoys or floats. Those floats that submerge, balance the total horizontal current-generated force or drag on the line, which is recorded on the tensiometer. These readings are a measure of the total current forces acting on the line by the surface and subsurface currents to permit the ready determination of the total kinetic energy of the currents. Upon obtaining continuous readings of the strain gauge over a definite period, wave heights and lengths, as well as tidal and other cyclic and non-cyclic water movements of the body of water can be ascertained.

Abstract: A bowstring release mechanism and, more particularly, a mechanism which incorporates an adjustable trigger. The trigger allows the trigger mechanism to be adjusted to a degree of sensitivity that will permit a spring mounted sear to releasably hold a rotatable bow string release member when the trigger mechanism has been actuated and has been removed from engagement with the sear.

Abstract: An apparatus for sensing the orientation of an inclinometer in both direction and magnitude for determining the velocity and direction of currents in a body of water having a magnetic north seeking sphere buoyantly supported in a housing. Implanted on the sphere is a plurality of tuned circuits of different resonant frequencies set at right angles to each other and a sense-drive winding or coil mounted about the housing. Upon applying a series of pulses of voltage to the sense-drive coil, the tuned circuits will oscillate with decaying amplitude at their resonant frequencies in the intervals between the pulses of voltage. The mean voltage across each of the tuned circuits is a measure of the amount and direction of tilt of the housing caused by the currents. The sense-drive coil senses these voltages across the tuned circuits and between the induced pulses of voltages, will transmit them to conventional recording equipment whereby a continuous determination of the currents velocity and direction are obtained.
