Abstract: An external skeletal fixator for treating an injured mammalian limb, such as a horse's foreleg, includes a plurality of transfixation pins which transfix the bone at separated sites along the limb proximal the injury and terminate beyond the limb; means, exemplified by an organic polymer, for rigidly connecting pin terminii to a weight bearing member carried beneath the foot of the limb; together with means, e.g., affixing said weight bearing member to the foot of the limb, for immobilizing the limb distal the injury, whereby the weight of the mammal is transferred from the limb proximal the injury to the weight bearing member, permitting the mammal to ambulate while the injury heals.
Abstract: A hand-held snuffer for extinguishing a fire in a vessel, such as a kitchen pan, which includes a soft, compressible, resilient, nonflammable mat, means to support the mat to present a substantially flat, flame-contacting face, and means for grasping the supported mat and laying it on the flaming vessel.
Abstract: A water sterilization system includes a sterilizer having a plastic housing and a sheath inside the housing which transmits untraviolet light from an enclosed lamp. The housing is protected from uv degradation by means of a reflective liner. A fail-safe control mechanism is provided which includes a normally closed water valve held open by a stallable electric motor electrically in series with a photoresistor which senses the ultraviolet light.
Abstract: A delivery system for therapeutic fluids including an implantable fluid receptacle and means to anchor a transcutaneous fluid delivery conduit on the surface of the body, together with a method of using the system for the long-term administration of fluids to selected sites in the body.
Abstract: Apparatus is provided for mooring a water-borne boat to a dock. The apparatus includes a pair of spring wires extending from the dock and over the water to brackets supporting a horizontal roller to be engaged by a boat-mounted latch.
Abstract: A kit for making a three-dimensional picture includes a frame encircling a three-dimensional window into which may be inserted a plurality of substantially planar decorated scenes. The depth of a scene in the window in determined by bending backward resilient hinges carried at the edges of the scene. The scenes are removably anchored in the window by frictional engagement between the hinges and the inner sides of the frame. Cut out regions in the scenes permit more remote scenes to be viewed, creating a three-dimensional effect. Including replicas of scenes allows more than one picture to be created with the kit.
Abstract: [1,1'-Biphenyl]-3-ylmethyl pyrethroid esters, as well as processes, uses, and intermediates thereto, are disclosed. The [1,1'-biphenyl]-3-ylmethyl pyrethroid esters control a broad spectrum of insects as well as acarids.
Abstract: .alpha.-cyano esters are prepared by reacting an acyl halide with an aldehyde in a homogeneous mixture of substantially water-miscible aprotic solvent and an aqueous solution of water-soluble cyanide salt.
Abstract: Lactones of the formula ##STR1## wherein R is hydrogen or a CX.sub.3 group, and each X is a chlorine or bromine atom, are converted to the known cis-3-(2,2-dihalovinyl)-2,2-dimethylcyclopropanecarboxylic acids or lower alkyl esters, from which pyrethroid insecticides are obtained.
Abstract: Insecticidal compositions containing N-aminosulfenyl derivatives of carbofuran are stabilized against spontaneous decomposition by incorporating an epoxide compound therein.
Abstract: Compositions comprising, in combination, the insecticides endosulfan and 2-dihalovinyl-3,3-dimethylcyclopropanecarboxylates exhibit synergistic insecticidal activity. The novel compositions are exemplified and their use for controlling insects is demonstrated.
Abstract: Compositions comprising, in combination, the insecticides methomyl and 2-dihalovinyl-3,3-dimethylcyclopropanecarboxylates exhibit synergistic insecticidal activity. The novel compositions are exemplified and their use for controlling insects is demonstrated.
Abstract: Sulfur dioxide is removed from a gas stream by contacting the gas with an aqueous solution containing sulfite anion, magnesium cation, and one or more other cations whose sulfite salts are more soluble than magnesium sulfite. The contacting solution is regenerated with magnesium oxide or hydroxide and then recycled.
Abstract: Optically active 1-Trichloromethyl-3-methyl-2-butenyl acetoacetate is prepared by resolving the racemic ester via a crystalline enamine derivative.
Abstract: Certain alpha-cyano esters are prepared by reacting an acyl halide with an aldehyde in a substantially water-immiscible aprotic solvent and an aqueous solution of water-soluble cyanide salt in the presence of an amphoteric surfactant rate-promoting agent.

Abstract: Certain alpha-cyano esters are prepared by reacting an acyl halide with an aldehyde in a substantially water-immiscible aprotic solvent and an aqueous solution of water-soluble cyanide salt in the presence of a rate-promoting agent selected from acid salts of tertiary amines.
Abstract: Certain alpha-cyano esters are prepared by reacting an acyl halide with an aldehyde in a substantially water-immiscible aprotic solvent and an aqueous solution of water-soluble cyanide salt in the presence of an amine or cryptate rate-promoting agent.
