Abstract: A method for protecting animal derived foodstuffs against spoilage which does not require refrigeration. The foodstuff is immersed in a stabilizer composed of a buffer solution, a proteolytic enzyme, and an antioxidant following which it may be stored at room temperature. The foodstuff can be reconstituted by rapidly reversing its pH by immersion in a hypotonic solution to kill bacteria present in the foodstuffs and then first immersing it in a hypertonic solution to eliminate the hypotonic solution and then rehydrating it. Alternatively, the foodstuff may be utilized, typically as an animal food and in meal form, without reconstituting it.

Abstract: A high frequency transformer for a wide range of frequencies and of the kind comprising a winding means attached on a core means, the winding means consisting of two parallel conductors isolated from each other, of which conductors one constitutes a primary winding, and the winding formed of the two conductors connected in series constitutes a secondary winding in a transformer coupled by economy coupling with a transforming ratio of 1:2. The conductors are wound on two parallel cores of soft magnetic materials spaced apart and connected by yokes at both ends. The winding pattern between cores lies in figure 8 patterns with opposite coils of the 8 patterns on each of the two cores.

Abstract: A process and installation for the production of powdered, surface-active, agglomeratable, calcined material, specifically calcined lime, from a material or raw material present in the form of sludge, scum or the like such as the waste materials in the sugar industry. One specific example of the process is production of calcined lime and/or usable CO.sub.2 from waste materials existing in the sugar producing industry. The installation in which the process is carried out includes a special calcining or reaction chamber which provides parallel flow paths with a turbulent vortex zone within which the raw materials are subjected for controlled periods to desired reaction temperatures.

Abstract: A liquid detergent capsule is packaged in an open-ended carton formed from a single elongate strip having transverse fold regions, the top and bottom walls of the carton being formed with wells confining the top and bottom of the capsule and there being coaxial central posts projecting centrally in the wells into adjacent recesses in the capsule.

The compounds include free acid, amide and/or ammonium salt forms of citric acid, glycolic acid, glucuronic acid, galacturonic acid, glucuronolactone, gluconolactone, .alpha.-hydroxybutyric acid, .alpha.-hydroxyisobutyric acid, lactic acid, malic acid, mandelic acid, mucic acid, pyruvic acid, methyl pyruvate, ethyl pyruvate, .beta.-phenyllactic acid, .beta.-phenylpyruvic acid, saccharic acid, tartaric acid, tartronic acid, and .beta.-hydroxybutyric acid. The therapeutic composition may include one or more of the compounds present in the total amount of from one to twenty percent.

Abstract: Packaging systems composed of one or more containers in an outer receptacle fabricated from a synthetic material. Unique features of the system make it economical, facilitate its handling, manufacturing, and assembly; make it possible to stack like assemblies into stable aggregations with a minimum of wasted space; and provide other advantages including, but not limited to, protection and positive positioning of the container(s) in the receptacle and areas for display advertising on both the container(s) and the receptacles which are visible from the exterior of the outer receptacle.

Abstract: A self-aligning ring joint of the type used for joining concrete pipes, said ring joint including a novel sealing ring which in conjunction with specially adapted ends of the concrete pipes to be joined insures that the ring joint will maintain an equilibrium position whereby it is always symmetrical to the normal plane between the two pipe ends.

Abstract: Apparatus for processing particulate solids by fluid-solids contact which includes, in the illustrated embodiment, a reactor having a shell housing a rotatable, movable assembly or rotor for supporting a bed of solids and for displacing the solids from a first location where they are introduced into the reactor to a second location where they are discharged. As the solids are displaced, a process fluid is directed upwardly through the bed in a manner which causes the solids to circulate and come into intimate and uniform contact with the process fluid. Liquid can be sprayed into the reactor and into contact with the circulating solids.

Abstract: A bag spreader in the form of a relatively rigid plastic hoop temporarily inserted into the open mouth of a flexible plastic trash bag. The hoop includes integral, external spikes adapted to be driven into the ground through the bag. Leaves are then easily raked into the bag. An incline or guide may be provided to ease the raking of the leaves into the bag. A drawstring closure may be provided on the bag for later closing after the hoop has being removed, and the bag may further have a pair of holes for receiving the spikes of the hoop.

Abstract: A fuel burning stove for holding and burning fuel to heat the surrounding atmosphere in a room where the stove is employed. The stove includes a fire box which supports the fuel and where the combustion is sustained. An air inlet is provided to the fire box allowing the inflow of air for combustion with the fuel. The air is preheated upon entry into the fire box for mixture with volatiles formed by the burning fuel directed toward the entering air by a baffle means to effect a secondary combustion. In addition, a movable damper cooperates with the baffle to direct volatiles toward the incoming heated air when the damper is in the closed position and to provide a more direct path to the chimney when in the open position.

Abstract: Methods for shaping metallic workpieces which utilize a single faced die and the use of heat and pressure to conform the article to the shape of the die surface by creep forming.

Abstract: A lightweight accelerometer in a casing or housing, having a very small base member to mechanically contact a surface, vibrations of which are to be determined; a piezoelectric element connected to the base, a seismic mass connected to the piezoelectric element, at least one thin circular diaphragm peripherically fixed to the housing, and with the base, the piezoelectric element, and the seismic mass fixed on, and axially symmetric to, the center of diaphragm and a soft pad member on the housing providing support on and dynamically isolating the housing from the vibrating surface. Several embodiments are disclosed and in each embodiment vibrations are directly transmitted from the vibrating body or surface to the piezoelectric element through the base, a very small half of a steel sphere.

Abstract: Methods of separating solids from mixtures in which they are incorporated by milling the mixture in the presence of a fluorochlorocarbon.

Abstract: A truck vehicle carried boom and hopper system for lifting, transporting, and depositing a load of particulate material such as powder, granules or seeds into storage bins in material dispensing aicraft, including a hopper boom framework having spaced apart side bars pivotally mounted on the side bars on the front end of the vehicle mounted support structure. An extensible piston-cylinder hydraulic motor system is utilized to obtain various pivotal positions of the hopper boom. A manual hopper control valve is located in the bottom of the hopper, the hopper is pivotally mounted on a horizontal axis on the extended end of the boom and a safety bar is secured to a mid-portion of the boom to enable a safety block when the boom is in the aircraft loading position. Between the boom pivotal mounting on the truck frame and the truck frame is a trussed frame support construction which enables rigid pivotal support of the boom and hopper.

Abstract: An improved valve system for obtaining access to a container of fluid. In a container of fluid, and particularly a keg for beer, a valve assembly receiving member or keg neck extends from the top of the container. A sealing mechanism is provided to secure the valve assembly in sealed relationship with the keg neck and to allow access to the fluid contained by actuation of the valves. More specifically, the valve neck has a groove in its inner surface to receive a resilient retainer ring which maintains the valve assembly in place. In addition, a safety feature is provided to prevent inadvertent expulsion of the valve assembly should the retainer ring be dislodged while the keg is pressurized. A siphon tube extends from the valve assembly to a position adjacent the bottom of the keg when the valve is secured within the keg neck.
