Abstract: The invention concerns a sprinkler system for refrigerated spaces and sets the task of assuring a longer minimum-time functional capacity for such devices after they have been switched to the operating state. This objective is resolved by an overdimensioning of the piping in combination with special dry sprinklers.

Abstract: An apparatus for portioning dough has a filler hopper (31) for the dough in which hopper a pre-portioning tool (51) in form of two star rollers (32) is disposed which rotate in inverse direction and are driven by a drive device if the amount of dough in a chamber (30) below decreases a predetermined value. From this chamber the dough (30) is pressed by a pusher device (25) in receiving openings (4) on the periphery of a step-wisely rotated drum (2). The volume of dough in the chamber (30) is controlled by a capacitive sensor (35) embedded into the wall (36) of the filler hopper (31) so that this sensor (35) does not interfere with the stream of the dough.

Abstract: A toy archery set comprising a bow; a barrel rigidly attached to the bow; a movable plunger which has finger grooves and is longitudinally disposed within the barrel; a spring operably coupled to the plunger and to the barrel providing a projecting force either directly or through a pneumatic cylinder; and an arrow constructed of foam having fletching, a tip designed to adhere to a target, and a means to attach the arrow to the bow.

Abstract: A method for controlling the growth of bacteria and algae in utilitarian bodies of water such as industrial cooling towers, swimming pools and hot tubs is described. The method comprises adding to the water novel trivalent silver compounds. Said compounds are light stable and can be supplied as liquid concentrates which will not precipitate any silver whatsoever from saline waters nor will the concentrates stain skin or discolor surfaces. Said compounds meet the rigid EPA standards of killing 100% of select coliforms within ten minutes and are efficacious at concentrations as low as 1-2 PPM.

Abstract: Sling or tie-down webbing in the form of a strap whose edges are provided with protective warp yarn structure made up of bicomponent fibers that include a polyester core with a sheath of a polymer with a lower melting point than the polyester, which webbing has been subjected to a heat treatment sufficient to cause melting of said sheath, but not of the core.

Abstract: An elongate length of suture is passed through holes in a first small plate (pledget) and holes in a second small plate (pledget), the suture being then tied to retain the two small plates relative to each other and to retain in use tissue between the two small plates (pledgets).

Abstract: Ornamental device having compartments formed of net-like foraminous material and containing sparkle elements which are larger than the openings in the material, but having appendages whose outer ends are smaller than the openings so as to engage therein to inhibit movement of the sparkle elements within the compartments.

Abstract: System for determining the airspeed of helicopters, having a coupled measuring device to which is supplied by the cyclic and collective control signals, the attitude angles and the rotational velocities about the axes of the helicopter. The measuring device contains two models, namely a first model of the input behaviour of the helicopter motion, on which the cyclic and collective control signals act as input, and a second model of the system behaviour of the helicopter, on which the condition parameters act as input parameters. The estimated state parameters are obtained in an integration stage by integration of the algebraic sum of the outputs of the two models and the output signal of the correction arrangement, from which the values of the the velocity components are supplied to an indication. The integration stage is connected in front of a correction arrangement for the measured parameters of the rotational velocity and the attitude angle.

Abstract: A container assembly for foods includes a container portion, a cover portion hingeably attached to the container portion along a hinge axis, a handle portion on the container portion, and a pivot tab on the cover portion. The handle portion extends outwardly from the container portion adjacent the hinge axis and it includes an outwardly extending first portion having an opening therein and a second portion which extends downwardly from the first portion. The pivot tab is attached to the cover portion so that it is operable by a user for pivoting the cover portion to an open position, and so that the pivot tab passes downwardly through the opening in the first portion of the handle portion as the cover portion is pivoted to an open position.

Abstract: A toy gun includes a barrel assembly comprising a plurality of side-by-side barrel elements, a plurality of missiles which are receivable in the barrel elements, and a firing assembly for impacting sequential missiles in order to launch them from the barrel assembly. The firing assembly includes a resiliently deflectable firing member and a deflecting mechanism for deflecting and releasing the firing member so that it is resiliently propelled into impacting engagement with sequential missiles for launching the missiles from the barrel assembly.

Abstract: A novel molecular scale device is described which is bactericidal, fungicidal and algicidal. The antipathogenic properties of the device are attributed to electron activity indigenous to diamagnetic semiconducting crystals of tetrasilver tetroxide (Ag.sub.4 O.sub.4) which contains two monovalent and two trivalent silver ions in each molecular crystal. When the crystals are activated with an oxidizing agent, they release electrons equivalent to 6.4.times.10.sup.-19 watts per molecule which in effect electrocute pathogens. A multitude of these devices are effective at such low concentrations as 0.3 PPM where they can kill 100% of 100 K/cc Streptococcus faecalis, and E. coli colonies in three minutes meeting the ten-minute EPA criteria of 100% kills within ten minutes for swimming pool and hot-tub applications. The devices can be used in utilitarian bodies of water, such as municipal and industrial water reservoirs.

Abstract: An eccentric pulley mechanism for a compound archery bow includes an inner eccentric wheel pivotally mounted on the distal end of a resilient bow limb, and an outer pulley wheel which is rotatable relative to the inner eccentric wheel. The inner and outer wheels respectively include rotationally offset detents and notches which are operative for interengaging the inner and outer rotating wheels when the bowstring is pulled to a fully drawn position. As the bowstring is being drawn, the outer pulley wheel and its notch rotate about the inner wheel until reaching a maximum draw where the detent and notch engage and the inner and outer wheels become operable for rotating as an eccentric wheel. When the bowstring is released the engaged inner and outer wheels eccentrically rotate back and impart an increased velocity to the bowstring as it propels an arrow.

Abstract: A high temperature resistant seal for a catalytic converter is made from a high temperature resistant material including between approximately 28 and 60 dry weight percent high temperature resistant ceramic fibers and between approximately 20 and 50 dry weight percent high aspect ratio vermiculite. The seal is formed by mixing the resistant ceramic fibers with an aqueous dispersion of high aspect ratio vermiculite, applying the resultant mixture to a monolithic catalyst structure of a catalytic converter and heating the mixture and the monolithic catalyst structure to evaporate the water from the mixture. The seal and the monolithic catalyst structure can then be assembled in a housing to form a catalytic converter.

Abstract: A device for attracting and destroying insect pests utilizes a pressurized canister charged with either carbon dioxide or octenol or a combination thereof, or with insect pheromones, in combination with infrared and/or ultraviolet lights to attract a variety of insects, including mosquitoes and biting flies which prey on humans. The pressurized canister and fluorescent light source are surrounded by an electrified grid which electrocutes the insects when they try to reach the source of the attractant. A motorized cam mechanism is utilized for periodically discharging the contents of the pressurized canister.
