Abstract: Respirator of the mask-type covering the nose and mouth of a wearer to protect him from environments containing air-borne obnoxious particles and gases having a combination of a compressed air inlet regulator on the face of the mask, internal baffling which directs inlet air downwardly past the nose of the wearer, and spaces at the mask's sides in the wearer's cheek area and below his mouth to effect an air flow through and out of the mask in a downward direction with little annoyance to the wearer, to assist in exhausting exhaled breath from the mask, and to form an "air-curtain" at the mask's outlet spaces that prevents entry into the mask of obnoxious particles and gases. The mask is further adapted for quick coupling and uncoupling to and from supply lines of air under pressure and for use with air supply lines of widely varying supply pressures.

Abstract: Self-contained device for attachment to rural mailboxes which automatically signals when the mailbox door has been opened, including a channel support member, a signal flag pivotally connected to the channel support, a trigger element pivotally connected to the signal flag and shaped to cooperate with the channel support in setting the trigger mechanism, and separate biasing means for the signal flag and trigger element which allow the trigger mechanism to be easily set by a simple rotation of the signal flag and to be automatically released by an opening of the door of a mailbox upon which the device is mounted.

Abstract: Animal waste conversion into animal feed in a process and system including an electrochemical cell in which cell electrolytic conditions are controlled to promote growth of waste aerobic bacteria, without forming oxygen bubbles, and to produce hydrogen bubbles which are collected in the cell and then, in a fuel cell, converted into D.C. electricity that is utilized to supply the major portion of the electricity employed in the conversion cell. The system and process utilizes relatively concentrated waste liquor feeds to the conversion cell, e.g., from about 15% to about 10% total solids, and is adapted for continuous operations, e.g., as a supplemental feed-producing compliment to livestock-raising operations.

Abstract: Link unit of the U-shaped type for use in making continuous chains by interfitting connection with pintles of the base segment of the unit between and to the spaced leg segments of a preceding unit in the chain wherein the leg segments of the units are provided at their ends with slotted bosses for receiving a connecting pintle, the boss slots are adapted to receive plug welds to rigidly weld and attach a connecting pintle to the bosses, and outwardly extending arms are positioned on the leg segments of the link unit forward of and adjacent to the leg segment bosses. In preferred embodiments the plug weld slots are positioned on the rear faces of the leg segment bosses to minimize shear on the plug weld. The link is interchangeable with links in existing chain systems and has improved investment and operating cost characteristics and improved strength and wear properties.
