This invention is an apparatus for use in 100% leak testing of food containers used in conjunction with a tracer gas. It includes a shell with entrance and exit air locks to create a controlled atmosphere through which a series of containers is conveyed by a conveyor belt. Pressure in the shell is kept lower than that in the containers and the atmosphere is made to flow with the containers so that a tracer gas placed in the packages before sealing them will leak more readily, but the leaked tracer gas will remain associated with the leaking package as it moves through the shell. The leaks are detected with a sniffer probe in fluid communication with a gas chromatograph (GC). The GC issues a signal when it detects a leak to an ejector that eject the leaking container from the conveyor. The system is timed so that the series of containers can move continuously into and out of the shell, past the probe and the ejector, without stopping, yet each package is tested for leaks and removed if leaking.

Patent for an aromatic asphaltum and paraffin wrap to preserve, protect from air and moisture, and transport meat that will not become brittle under cold temperatures.

Patent for a new engine designed to maximize power output by using a single crank's bearing surface and increase the crank power without lengthening the piston travel.

Patent for a "locking [device] for automobile," especially "an attachment for use ... with the steering wheel and the steering columns or attachments" (lines 9-13). This device is effective as a lock, as it keeps the steering wheel from rotating and the "throttle actuating members or levers ... held against movement" (lines 14-16)

Patent for a new and useful improvement in orchard-heaters and smudge-pots to provide an improved drat flue and damper carried by a cap especially adapted for use in connection with heaters or crude oil smudge pots commonly used in various orchards during frosty weather. The invention aims to provide a draft flue and damper to withstand the most severe and erratic winds, the damper capable of being opened to suit any temperature, without impairing its efficiency in protecting the draft.

Patent for a process of making stock food from cactus. This process will produce food from spiny cactus and to be kept for a long period without decay.

Patent for a pump-plunger, concentrating on advancements in the design, particularly catering to deep well operations and environments with challenging conditions, such as oil and water wells where fluids are mixed with sand, sediment, or debris.

Patent for dipping vat used on live animals to remove insect infestation with a reduced risk of injury to the animal.

This invention relates to an improved well cleaner, and has for its principal object to provide a device of this kind adapted to be positioned in a well casing to direct a volume of air into the casing for cleaning the valves and straining elements thereof. A further object of the invention is to provide an automatic means for sealing the cleaner for holding the fluid within the well casing, against back pressure, during the cleaning operation. (Lines 8-19)

Patent for a roadway for automobiles built of rail tracks that accommodate different tire sizes, so that wheels may run along the rails inlaid on roads.

Patent for a type of monkey wrench in which the movable jaw of the wrench is mounted upon the fixed jaw so that it is easily shifted upon the disengagement of a detent for the fixed jaw. This allows the wrench to be held in any desired adjusted position with relation to the fixed jaw.
