Abstract: A selective deceleration brake control system which enables the operator of an aircraft or other vehicle to preselect a rate of deceleration for the vehicle. The system produces a velocity reference signal which decreases in value at a rate indicative of the rate of vehicle deceleration selected by the operator. A signal indicative of actual wheel velocity is continuously produced and compared with the velocity reference signal to generate an error signal. The error signal is processed and used to produce a brake control signal. The system continuously controls braking effort to cause the vehicle to decelerate at the rate selected by the operator. The selective deceleration circuit cooperates with an anti-skid brake control circuit such that at any instant the circuit providing the higher brake release command will control.

Abstract: Novel salts of substituted hydroquinone sulfonic acid having the general formula: ##STR1## in which R denotes ammonium or a cation of an organic base such as alkylamines, alkanolamines, arylamines, alkylarylamines, aralkylamines and cyclamines, or a cation of an alkali or alkaline earth metal such as lithium, sodium, potassium, magnesium or calcium. The structure of course depends on the valency of R. In every case, R' denotes a linear or branched alkyl group with 1 to 6 carbon atoms. These salts are used as haemostatic agents and protective agents against capillary fragility.

Abstract: Food products, for example, hamburger patties, are rapidly cooked with reduced weight losses. A cooking appliance is provided having a plurality of parallely spaced heat transfer fins from which project an array of cooking grills on which the hamburger patty is impaled. The appliance is adapted to be passed through a cooking environment so that heat is transferred through the fins and projecting grills to the interior of the hamburger patty. In this way cooking is accomplished in a relatively short period of time, and also the amount of fat and meat juices that are melted or broiled away is minimized. A device with a handle is provided for releasably engaging the cooking appliance so that the appliance can be conveniently moved even if hot. The device is provided with an ejection system for discharging the hamburger patty from the appliance.

Abstract: Pizza sauce is applied to pizza shells by a method in which the shells are held stationary and the sauce applied in a movement thereabove. The pizza shells are transmitted along a horizontal deck to a position at which the movement is interrupted for sufficient time to apply the pizza sauce to the pizza shells. A volumetric amount of pizza sauce is drawn from a supply source and furnished to distribution nozzles that rotate above the pizza shells. The distribution nozzles deposit the pizza sauce along the radii of the pizza shells while the distribution nozzles are rotated in a circle above the pizza shells.

Abstract: An anti-skid braking system for an automobile including apparatus for sensing rotational wheel speed, reference comparison apparatus for developing a signal indicating excessive rotational deceleration incident to incipient or actual skidding of the wheel for effecting brake relaxation and reference control apparatus for controlling the reapplication of braking effort.

Abstract: A method is provided for reducing mold spoilage of partially baked pizza crusts intended to be stored in unsealed packages at normal room or ambient temperatures. This method comprises properly reducing the moisture content and water activity of the crusts, cooling the crusts to below ambient temperatures, treating the surface of the crusts with ethyl alcohol, and packaging the crusts before significant amounts of alcohol can vaporize. The shelf life of partially baked pizza crusts so treated and stored in unsealed plastic packages at room temperatures can be extended to at least about 20 weeks or more as compared to about one week without such treatment.

Abstract: The stereo-isomeric penicilloyl-polylysine conjugates having high optical dextro-rotations are useful for eliciting cutaneous responses in persons with penicillin hypersensitivity.The process for manufacturing the above-entitled stereo-specific conjugates reacts penicillin with neutralized polylysine hydrochloride in a non-aqueous polar solvent such as dimethyl sulfoxide.

Abstract: A method for making a sterile connection between fluid passage means such as a port structure for passing sterile fluids or other biological material, is disclosed. The port structure includes a flexible sleeve having a rigid thermoplastic tube secured therein. The outer surface of the sleeve has greater thermoplastic properties than the inner surface, enabling the sleeve to be heat sealed to the fluid passage means without sealing off the inner surface. The rigid tube has a free end extending outside the sleeve, having a thermoplastic diaphragm which seals off the free end. When a sterile connection between two fluid passage means incorporating the port structure is desired, the free ends of each rigid tube are aligned and softened, and each thermoplastic diaphragm is opened. The free ends of the rigid tubes are then brought into contact and held in position under a slight pressure while the thermoplastic tubes cool and solidify, thereby creating a permanent connection.

Abstract: Cup-shaped shells suitable for use as hors d'oeuvres, snacks, and the like are made from leavened dough. The shells are cut from a crust of leavened dough and then shaped by dies and heated to form a concave configuration.

Abstract: A floating liquid aerator includes an axial flow impeller rotated by an electric motor and disposed within a tubular throat to pump water from a pond upwardly through the throat and against a rotatable diffuser which slings the water outwardly for interface contact with the surrounding atmosphere. Being rotatable, the diffuser slings the water into the atmosphere with considerable turbulence thereby exposing more of the water droplets to the atmosphere and resulting in a higher transfer of oxygen to the water. The impeller comprises a series of angularly spaced blades formed with a rectangular cross-section to reduce power losses caused by drag and to increase the volume of water capable of being displaced by the impeller. Each blade is twisted longitudinally with a progressively decreasing attack angle from its root to its tip and, in addition, all of the blades are twisted identically to provide a statically, dynamically and hydrodynamically balanced impeller. .Iadd.
