Abstract: A storage appliance for use with tubing, pipes and similar items. A generally U-shaped member carries a peg at a distal end of each of its legs and a coupling device at their proximal end. The pegs have a first portion of a generally circular cross section and taper to a rounded point at one terminus. The coupling device has an aperture of the same general cross section as the peg first portion. A storage rack is assembled from the appliances by inserting the pegs of one appliance into the coupling devices of another, the number of appliances used being dependent upon the particular storage requirement. The distal ends of the legs of each appliance are made flat to provide a mating surface for an appliance placed thereon while the tapered pegs allow a cooperation between the pegs of one appliance and the coupling device of another even when the legs of the peg-carrying appliance are spread due to loading or otherwise.

Abstract: A transvenous lead including a conductor encased in an insulating material which is generally inert in body fluids and tissues, the conductor being connected to an exposed, electrically conductive electrode at, or adjacent to, the lead terminus. At least one tine extends from the casing adjacent the lead terminus for engaging the inner wall or trabeculae of an internal body organ or chamber to urge the electrode in a given generally transverse direction, all of such tines extending from the casing in directions which fall within an 180.degree. arc around its periphery with no tine extending in a direction less than 90.degree. from the given direction. In one preferred embodiment, the electrode forms a conductive lead tip and includes a portion skewed toward the given direction.

Abstract: A device for preventing arrhythmias such as fibrillation in which a plurality of electrodes are placed at selected points on a heart to sense depolarizations. An astable multivibrator receives the depolarization signals from the electrodes and provides an output signal to a device which in turn provides cardiac stimulation signals to all of the electrodes on the heart for the purpose of preventing the arrhythmia. The multivibrator is preferably synchronized to the QRS complex of the heart with its refractory period. In a second embodiment of the device, separate sensing and stimulation electrodes are used.

Abstract: A stackable poultry coop formed of complementary upper and lower sections and a door. The upper section has an upper wall with a central opening bounded by a plurality of upwardly extending flanges. The lower section has a lower wall formed of a flexible grid and a plurality of downwardly extending ribs adapted to engage and nest with the flanges of another coop when in stacking relation thereto. The lower wall ribs are positioned around the periphery of the lower wall to allow at least its central portion to flex and each of the upper and lower walls have a marginal wall extending generally at right angles from their periphery. The upper, lower and marginal walls are provided with a plurality of openings to provide ventilation as well as to facilitate cleaning.
