Abstract: An attachment to a fence, such as a chain link fence, used to confine a dog, prevents the dog from climbing the fence or using the top of the fence to assist himself in escaping over the fence. The attachment creates a region of instability, superjacent the top of the fence, which will not support the dog's weight and thus does not allow the dog to cling to or push off of the top rail of the fence. The region of instability is created by a freely rotatable roller attachment or a flexible panel attachment, both of which yield under the weight of the canine.

The present invention provides a novel method for manufacturing the aforesaid lath panel wherein the marginal ribs are formed concurrently with the formation of the strands, wherein a punch press commonly used to form the strands is fitted with forming surfaces which progressively bend and fold at least one lateral edge of the lath panel to form at least one marginal rib in sequence with the formation of the strands.

Abstract: An improved drain trap assembly which is designed to allow for disposal of sediment with reduced mess and uncleanliness. The improvement comprises a valve which is attached to a drain trap and a compressible container attached subjacent to the valve which collects the sediment. The container when compressed forces residual fluid through the valve such that the valve can be closed to prevent flow of residual fluid back into the container; thereby, the volume of residual fluid in container is reduced prior to removal of container from drain trap. The container is then removed and the sediment is either discharged from the container or the disposable container is discarded. A reduction in discharge of unclean residual fluid into the surrounding area is accomplished by the improvement.

Abstract: An apparatus to be used in field studies of varying fish populations allowing visual display and photographing of live specimens without the excessive handling or undue stress normally accompanying such examination. The apparatus is made of a substantially rigid transparent material in the form of a V-shaped or W-shaped tank. This design allows a specimen to be wedged into position between converging viewing plates without exerting undue pressure to the specimen's body. The tank includes side plates which are fused with the viewing plates with a non-toxic adhesive material allowing the tank to be filled with water. A base plate is attached to the bottom of the V-shaped tank so that it may stand on its own. The W-shaped tank does not include a base plate so that all three troughs may be utilized.
