Abstract: A spherical ball, for projection through the air to deviate from an expected trajectory, has a first hemisphere (12) and a second hemisphere (14). The surfaces (52, 54) of the first hemisphere (12) and the second hemisphere (14) are generally smooth, except for the provision of a simulated seam (53) which gives the ball the appearance of a baseball. An insert (40) of felt-like material is provided in the second hemisphere (14), with the surface of the insert (40) flush with the surface (54) of the hemisphere (14). When the ball is projected along the plane of the line (16) between the hemispheres (12, 14), it will deviate from that plane in the direction of the first hemisphere (12). The ball is manufactured by locating the insert (40) in a mould (60) and injecting polyurethane foam (64) into the mould (60) with the insert (40) bonding with the foam (64).

Abstract: In a device (12) adapted to dissuade a dog from barking, there is provided a reservoir (30) of spray material (50) associated with a collar (14) which encircles the dog's neck (16). The reservoir (30) includes at least one wall (32, 34, 36, 38) member defining an interior volume for the receipt of spray material (50) therein. The reservoir (30) includes a first dimension (i.e., a centerline) which lies within the median sagittal plane of an erect dog which is facing forward, thereby orienting one portion of the interior of the reservoir (30) vertically lowermost. An exit port (54) is provided for the transport of spray material (50) from the interior to the exterior of the reservoir (30). A semi-rigid, lengthwise substantially non-compressible, conduit (62) having a first end (64) thereof connected in fluid flow communication with the exit port (54), extends from the exit port (54) and terminates at its opposite and open end at the vertically lowermost interior portion of the reservoir (30) when the present appliance (10) is mounted at a location on the collar beneath the lower jaw (31) of the dog. The length of the conduit (62) is chosen to exceed the straight-line distance between the exit port (54) and the vertically lowermost portion of the reservoir (30) by an amount sufficient to provide for wedging of the conduit (62) against at least one interior wall of the reservoir (30) opposite the exit port (54) and preferably opposite to terminal open end of the conduit (62).

Abstract: The present invention provides methods for expanding coiled tubing within a wellbore in order to form a patch. In one aspect, an expansion assembly is run into the wellbore at the lower end of a string of coiled tubing. The expansion assembly includes a cutting tool and an expander tool. The coiled tubing is run into the wellbore such that the expander tool is adjacent a portion of surrounding casing or other tubular body to be patched. The expander tool is actuated so as to expand a selected portion of the coiled tubing into frictional engagement with the surrounding casing, thereby forming a patch within the wellbore. The cutting tool is actuated so as to sever the coiled tubing downhole above the patch. The severed coiled tubing is then pulled, thereby removing the expansion assembly from the wellbore as well.

Abstract: A web (36) of paper or the like has labels (42) defined therein by printing the web (36) followed by skip cutting (40) the web to define the label boundaries. The skip cutting (40) leaves the labels (42) connected to the remainder of the web (36) by breakable catch points (44). The labels (42) are rendered capable of being applied to product containers (16) by the web (36) having adhesive applied to the side opposite the printing, and the web (36) is rendered capable of being wound up by having an adhesive release coating, such as silicone, applied over the printing. By providing such a construction, the web can be fed through conventional applicator machinery in which, as the web passes over an applicator beak, sequentially the label leading edges of the labels protrude from web, and attach to product containers moving synchronously through the machinery, and as the application process continues, the catch points break resulting in complete removal of the labels from the web and application to the containers.

Title: Cell transport compositions and uses thereof
Inventor: GELBER COHAVA
IPC: A61K9/12
Filed: 2003-08-01
Granted: 2014-11-18
Abstract: Compositions and methods have been developed for transporting compounds across membranes with little or no toxicity and, when targeted through the appropriate routes of administration (i.e., lung, gastrointestinal (GI) tract), little or no immune stimulation. The compositions can mediate cellular delivery of compounds that would otherwise not enter cells and enhance the intracellular delivery of compounds that would otherwise enter cells inefficiently. The methods are carried out by contacting a proximal face of a lipid bilayer or membrane (e.g. the surface of an intact cell) with a complex containing a compound (e.g., a therapeutic agent) and a diketopiperazine (DKP). DKP and the compound are non-covalently associated with each other or covalently bound to each other .
