Abstract: A mold inhibitor composition that has particular utility for the preservation of animal feeds, and a method of making such composition. The composition is an aqueous solution of one or more salts or propionic acid, one or more deliquescent materials, one or more humectants, and in certain forms of the invention monosodium glutamate is included. This composition makes propionate ions available for mold control just as effectively as propionic acid, but without either the bad odor or the serious corrosive characteristics of propionic acid. The deliquescent material serves the surprising function of keeping moisture from accumulating in feed adjacent the walls of feed bins or from condensing on the walls to minimize mold in this heretofore uncontrollable region.

Abstract: A mold and dust inhibiting composition which has particular utility in connection with the use of animal litter such as poultry litter, as well as having general utility for controlling both mold and dust. The composition of the invention is an aqueous solution of one or more salts of propionic acid, one or more deliquescent substances, and also preferably one or more humectants. Propionate ions are made available for mold control by this solution just as effectively as propionic acid, but without the disadvantages of propionic acid including a bad odor, serious corrosive characteristics, and high volatility and hence short residual time. The deliquescent, and preferably also the humectant, prevent moisture from migrating toward container walls where there is a large day/night temperature differential, and also prevent dry regions from developing and producing potentially harmful dust. Addition of lecithin to the product as a lubricant provides additional protection against dust being generated.

Abstract: A test fixture operative to simulate seat belt assembly installations. An articulated arm assembly, comprising a primary arm and a secondary arm, has its primary arm lower end mounted by a dual pivot of a support base at the origin of X and Y axes of an X, Y and Z coordinate system. The anchor position of the seat belt retractor is adapted to be releasably fixed on the support base relative to the X and Y axes. The seat belt webbing pillar turning loop is pivotally and linearly adjustably supported on the secondary arm. A motorized load transducer, located on the primary arm, extracts the seat belt webbing from its stowed position on the retractor providing measurements of the forces required to perform this action. The test fixture allows various changes in vehicle seat belt system components to be measured thereby readily determining the optimum installation geometries for a seat belt system that is comfortable and easy to use.

Abstract: A package of imbricated bags is provided that is adapted for dispensing and opening such bags one at a time. The package includes a chain of adhesively imbricated bags in overlying sequence, each bag being adhesively but releasably attached to adjacent bags and having an open mouth end directed toward the leading end of the chain, and a container for the chain having an elongate, constricted opening through which the leading end of the chain is directed. The length of the opening is less than the bag chain width by a selected extent sufficient to cause the mouth of each bag to open in response to transverse constriction as the chain is advanced through the opening, provided that the width of the opening is sufficiently narrow so as to resistively confront the lower edge of the mouth of a bag being pulled through the opening. A method for making the bag package is also provided.

Abstract: A childproof protective device adapted to be secured on an electrical wall outlet. The device includes a plate having openings therethrough which are in register with the plug receptacles of the outlet when the device is mounted thereon. The plates carries a pair of slidable doors or panels which can be releasably locked in position to prevent a child from gaining access to the plug receptacles.

Abstract: A wicketed bags packet is provided that comprises a stack of flattened, flexible plastic bags having two wicket holes therethrough; wicket shanks extending through said wicket holes respectively; and elongate, flexible binding members crossed in an under-to-over pattern between said shanks and forming a handgrip for said packet, each said binding member being affixed to a shank, respectively, at the rear of said stack and extending to and being removably and reclosably affixed to the other of said shanks at the front of said stack. An associated method for dispensing wicketed bags is also provided.

Abstract: This invention relates to the key case that is adapted to be attached to a fixed location on or adjacent a door that is attached to a casing by hinges and has a lock openable with a key. The key case has a sleeve for receiving the conventional hinge pin of an interleaved hinge so that the key case is located in a readily locatable position with respect to the door. The key case has a retracting mechanism with a flexible member attached thereto and the key attached to the free end thereof. Stop means are located within the key case and define a stored position for the key wherein a portion extends through an opening in the case to be gripped by a user and retracted and moved to the lock. The retracting mechanism automatically returns the key to the stored position whenever it is dropped or released.

Abstract: A key construction comprising a pair of key shanks joined at one end to provide a unitary body portion having aligned, oppositely extending key bits each of which is adapted for use in a different lock tumbler. In one of its forms, the key shanks are secured in end-to-end relation by means of a sleeve. The sleeve desirably is provided with a pin to which an end of a key bit receiving and holding member is attached. The key bit receiving and holding member advantageously is constructed in a manner to enable only one of the key bits to be pivoted from a normally, inoperable position in the receiving and holding member to an operable, lock tumbler engaging position. Thus, one key bit can be easily and readily distinguished from the other key bit, and there can be no mistake as to which key bit is to be engaged in which lock tumbler.

Abstract: This disclosure is concerned with resolving monophonic-stereophonic signal reception indication ambiguities through the development of channel difference signals, by appropriate filtering and compression, that distinguish the stereophonic mode.
