Abstract: This invention describes feed supplement, and processes which increase the amount of essential fatty acids in the milk, eggs, meat and other by-products from animals including dairy cattle, beef cattle, goats and poultry. The food supplement described herein includes specific fish meal, fish oil, algae or plant dietary supplements combined with a natural ingredient/coating mixture, which can be either talc, clay or combinations; or mixtures of talc or clay with flax sprout powder to achieve enhanced levels of the essential fatty acids in the milk, eggs, meat and processed livestock products from animals fed this dietary supplement. In ruminants, the natural ingredient/coating mixture prevents microbial degradation of the essential fatty acids in the rumen stomach of the animals fed with this composition, thus providing more of the essential fatty acids to the animal, for their use. This in turn results in improved concentrations in the milk, meat and processed products from these animals.

Abstract: A backup flight control system for controlling the flightpath of a multi-engine airplane using the main drive engines. The backup flight control system comprises an input device for generating a control command indicative of a desired flightpath, a feedback sensor for generating a feedback signal indicative of at least one of pitch rate, pitch attitude, roll rate and roll attitude, and a control device for changing the output power of at least one of the main drive engines on each side of the airplane in response to the control command and the feedback signal.

Abstract: An ignition key mounted on the steering column of a motor vehicle turns a gear wheel as the key is rotated among multiple positions. The gear wheel continually meshes with a steering column lock actuator assembly and moves the assembly according to the position of the ignition key and gear wheel. The actuator assembly defines a cam surface, which causes a pawl to pivot when the ignition key is moved to a lock position and permits the pawl to return to an unlocked state when the ignition key is moved from the lock position. The gear shift mechanism includes a tube pivotably supporting a gear shift lever at one end and a control selector lever at its opposite end. A plunger, in continual contact with the gear selector lever and control lever, is resiliently biased by a spring toward a position that brings the control lever into contact with detent surfaces on an insert. The tube defines a slot, aligned axially with a recess formed on the plunger, displaceably mounted within the tube.

Abstract: An instrument for measuring the concentration of a wide variety of important chemical and biochemical substances is provided which comprises an enzyme based voltametric sensor, and electronic circuitry for conditioning an output signal from the sensor. The instrument includes one or more aqueous oxidase enzymes mechanically coupled to a polarographic cell oxygen detector wherein the concentration of a substance is inferred from measurement of the depletion of oxygen resulting from an oxidation reaction catalyzed by the oxidase enzyme. The electronic circuitry includes current to voltage conversion, nulling an unneeded base current signal, and temperature compensation.

Abstract: A personal flotation assistance device includes a housing having an open end, a cover pivotally movable from a first position closing the open end and a second position opening that end, a container of pressurized fluid having a frangible membrane, a pin for puncturing the membrane, an expandable envelope disposed in an initially collapsed condition, and a gear assembly connecting the cover and pin. User manipulation of the cover to move the same from its first to its second position causes pin movement both rotationally about its axis and translationally along that axis into membrane puncturing abutment, thereby releasing the pressurized fluid for inflating the envelope to provide the user with flotation assistance. Cover movement to its second from its first position additionally serves to clear the housing open end thus enabling expansion of the inflating envelope outwardly from the housing interior.

Abstract: A device for opening food pouches including a spring loaded handle provided with stripping rods and a pouch cutter. The stripping rods pivotally engage one another so that a heated food pouch may be grasped by the opening device in tongs-like manner. The stripping rods include opposing smooth planar abutting surfaces for stripping food away from the end of the pouch to be opened. A cutting blade, preferably hook-shaped in configuration and mounted adjacent the free end of one of the stripping rods is operable to slit the pouch, while the pouch is still in the grasp of the stripping rods, by retraction of the device relative to the pouch.

Abstract: A subtractive photographic printer is capable of providing extremely short exposure time by coordinating the operation of a shutter and color filters. The shutter is normally positioned in the light path, and is driven out of the light path at the beginning of an exposure cycle. The exposure in each color channel is terminated by driving the color filter associated with that color channel into the light path in a direction which is essentially the same as the direction in which the shutter was driven out of the light path. In addition, the filter is driven into the light path at essentially the same rate at which the shutter was driven out of the path. The exposure time for the color channel is determined by the time delay between actuation of the shutter drive and actuation of the filter drive, since the shutter and the filter move in the same direction and at essentially the same rate.

Abstract: A neghold assembly for use in a photographic printer includes a bottom clamping surface, a pivot arm, a top clamping plate fixedly attached to the pivot arm, a solenoid upwardly engaging the pivot arm and a bias spring for upwardly engaging the pivot arm. The bottom and top clamping plates have apertures that allow light to be transmitted through the photographic film being held between the top clamping plate and the bottom clamping surface for exposing photosensitive print film. The solenoid engages the pivot arm on the side opposite of the pivot point from the top clamping plate. The solenoid pivots the top clamping plate about the pivot point to a clamping position whereby the top and bottom clamping plates are clamped together to hold the film negative. The bias spring pivots the top clamping plate upwardly from the clamping position to an open position when the solenoid is deenergized.

Abstract: A photographic printer has a punch marking system for placing cut and end-of-order marks on the photographic paper. The punch marking mechanism is adjustable to accommodate different widths of print paper. The punch marking mechanism includes guide rods which are positioned transverse to the path of the print paper. First and second carriage assemblies are movable along the guide path defined by the guide rods on opposite sides of the center line of the paper path. A lead screw moves both the first and second carriage assemblies along the guide path in an essentially symmetrical manner about the center line of the paper path. The punches or other marking devices are carried on the first and second carriage assemblies.

Abstract: A film cleaning apparatus for cleaning the photographic film prior to printing includes special guides which permit the film cleaning apparatus to be used with both first-run production and tabbed reprint production. The film cleaning apparatus is of the type having a pair of support members in opposed relationship which define a nip which is disposed transverse to the path of the photographic film. Two lengths of soft, lint-free wiping cloth extend through the nip with the opposed surfaces of the cloth at the nip defining a part of the path. The guide includes first and second generally parallel guide plates having opposing surfaces defining an opening which is part of the path. The opening defined by the guide plates has an inlet end and an outlet end, and the plates are in fixed position with respect to the film cleaning apparatus with the outlet end of the opening proximate the nip.

Abstract: A variable working distance photographic printer receives paper from a supply magazine through a first fixed opening and supplies the exposed print paper through a second fixed opening to a take-up magazine. The variable working distance is achieved with a movable paper deck within the photographic printer. Variable guides are provided between the first and second fixed openings and the movable paper deck in order to accommodate variations in the position of the movable paper deck. Variable working distances are provided, therefore, without requiring that the supply and take-up magazines be movable.
