Abstract: A flight simulator arrangement wherein a conventional, movable base flight trainer is combined with a visual cue display surface spaced a predetermined distance from an eye position within the trainer. Thus, three degrees of motive freedom (roll, pitch and crab) are provided for a visual proprioceptive, and vestibular cue system by the trainer while the remaining geometric visual cue image alterations are developed by a video system. A geometric approach to computing runway image eliminates a need to electronically compute trigonometric functions, while utilization of a line generator and designated vanishing point at the video system raster permits facile development of the images of the longitudinal edges of the runway.

Abstract: Disclosed is a combination of a frame, a mount, and a boom, wherein the boom retains a workpiece, such as a mower, about its free end and is rotationally attached to a pivotal mount at its other end. The pivotal mount or rocker arm is attached to the frame and permits the boom and workpiece to be centered over the frame for transport. The entire assembly preferably is mounted on the back bed area of a truck or tractor.

Abstract: A roof-drilling system for use in subterranean mining applications and the like in which the drill head of a roof drilling machine is arranged such that the receiving cavity of its chuck is configured having a lost motion association with the drive-in portion of starter and driver drill steel rods. The lower surface of a retainer fixed to the drill head and having a non-circular aperture formed therein serves to define one bearing surface for utilizing the drill head itself to pull the assemblage of drill steel from a completed bore. To remove the drill steel driver component from the drill head chuck, the miner grasps the lowermost portion and rotates it a relatively small amount, for example about 1/8 turn. To provide for interlocking of the various components of the drill steel, i.e.

Abstract: Disclosed is an air pressure release assembly, which preferably is a valve, for attachment to a grease gun to release air pressure within the gun which air pressure retards dispensing of grease from the grease gun.

Abstract: A lighting system for bicycles and the like which incorporates forwardly and rearwardly mounted lighting assemblies. Each of these assemblies includes right and left turn indicator lamps mounted within housings each having an outwardly directed lenticulated lens, the discrete facets of which protrude in a direction outwardly from an associated lamp. These lenses are utilized in conjunction with lower energy level inputs to the lamps in which an oscillatory circuit to optimize the consumption of energy from a bicycle mounted battery power supply. The batteries of this supply as well as impedance and oscillatory logic circuitry in addition to a recharging circuit are mounted in a unitary housing which is readily removable from the frame of the bicycle for purposes of leaving it unattended. Through the use of a harness incorporating a releasable electrical coupling, this more elaborate and expensive component of the bicycle may be retained for safe keeping when the bicycle is stored or parked.

Abstract: A stirring rod for use in a heating vessel which includes a contractable generally circular upper portion which is joined to a generally hooked shaped lower portion by a vertically extending rod section.

Abstract: Modified hormones or fragments of hormones are useful in producing antibodies when administered to an animal. Said antibodies in turn cause neutralization of endogenous natural protein hormones. The modification may be accomplished by attaching various kinds of modifying groups to the hormone or fragment. Modification may, for example, be achieved by chemically coupling diazosulfanilic acid groups to the hormone or fragment. The protein hormones to which this procedure can be applied are mammalian protein reproductive hormones such as, for example, Follicle Stimulating Hormone (FSH), or Human Chorionic Gonadotropin (HGG). These modified hormone or fragment may be administered to animals for the purpose of contraception, abortion, or treatment of hormone related disease states and disorders.

Abstract: An improved tactile control component for aircraft in which a tactile slide is positively driven through a box rack and pinion system from two oppositely disposed d.c. servo-motor assemblies. These assemblies include a relatively high RPM motor associated with a high gear reduction to achieve a positive and compelling tactile sensation at the hand of the pilot. Signals to the device are derived from the computer component of a flight director system or the like. To assure pilot tactile perception of the commands asserted through the apparatus, an emphasis is electronically inserted into command signals to accelerate the initial movement of the tactile slide at the inception of any given flight command. Through the relative positioning of the box racks in a mutually orthogonal disposition, the movement of the tactile slide may be along resultant vectors providing omnidirectional information particularly useful in controlling such components as the cyclic on rotary wing aircraft.

The apparatus for Quick Repair comprises an auxiliary assembly having means for securing it resiliently and quickly to a defective relay and having (1) an electrical coil; (2) a member movable by electrically created force in the coil to bear upon an operative movable member of the defective relay; and (3) electrical connections from the electrical coil to be connected to the means for normally supplying electrical current to the relay.

Abstract: An electronic siren wherein push-pull output transistor stages are used to drive an inductive load for producing an audible signal. Thermally induced base leakage currents are diverted from the transistor stages through the use of a control network which alternately removes a constantly asserted forward biasing signal therefrom. A current diverting network operating in conjuction with a series connected common emitter resistor serves to limit excess current flow at the output transistor stages and a shutdown network responding to a non-saturated on condition at either transistor stage serves to shut the circuit down in the event of short circuits and the like.

Abstract: Process and catalyst for curing resins (e.g. furans) comprising concentrated aqueous solutions of perchloric acid (about 45-72%) and the cured resins obtained using said catalyst. Improved catalyst combinations for curing resins in a process employing same and the cured resin produced thereby comprising concentrated perchloric acid, a small amount of phosphoric acid and/or a small amount of boric acid.

Abstract: Method and apparatus for sorting objects exhibiting identifiable dynamic response to vibrational phenomena, such objects including potatoes, onions, tomatoes and other comestibles. The system utilizes an elongate sorting zone incorporating a surface which oscillates at a predetermined frequency and amplitude which varies from a minimum at the input of the zone to a maximum value at the output thereof. The objects to be sorted move along the zone supported from two positions for a coding interval promoting their dynamic reaction with the oscillatory surface. Objects with higher resilience characteristic are rejected from the zone, while those exhibiting a lesser resilence are transported therethrough. The oscillatory surface is dynamically balanced and readily mounted upon field harvesting devices. By adjustment of frequency of the sorting zone oscillatory surfaces, a multi-stage sorting system is made available.

Abstract: This invention relates in general to improved containers for the growth of plants which provide a better environment for the plant roots, and hence improved plant growth, by providing a better balance between the water and gaseous contents of the growing media. This is achieved through the use of indentations in the bottom and/or side(s) of the container, thereby, (1) increasing the surface area of the part of the container in contact with the growing media, (2) reducing the average distance a molecule must diffuse in the growing media from roots before encountering a media-air interface (and vice versa) and (3) reducing th proportion of relatively water saturated growing media in the container.

Innoculation is carried out before the animals are subjected to stress factors, including weaning and transportation to feedlots. Also described is a method for preparing the vaccine by incubation of P. hemolytica within an infusion broth.
