  • Patent number: 4241519
    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.

  • Patent number: 4226290
    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.

  • Patent number: 4201770
    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.

  • Patent number: 4195802
    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.

  • Patent number: 4180809
    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.

  • Patent number: 4176750
    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.

  • Patent number: 4173097
    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.

  • Patent number: 4168563
    Abstract: A system, and apparatus for cleaning carpet and textile floor coverings which provides for a first detergent spraying followed by a second jet spraying with a liquid incorporating a cationic surfactant accompanied by a substantially simultaneous suctioning off of the deposited second liquid. The apparatus of the system includes a mobile frame arrangement with two adjacent tanks, one carrying cleaning solution and the other carrying the noted surfactant. Solenoid actuated valves control the delivery of these liquids through a wand to the carpet being cleaned. The apparatus includes a power conserving feature providing for a direct coupling between the motor of the apparatus and a suction blower and a simultaneous belt drive coupling to a liquid pump. The design of the apparatus is such as to minimize the physical effort required during its use.

  • Patent number: RE30904
    Abstract: An improved gamma camera arrangement of a variety utilizing a solid state detector, preferably formed of high purity germanium. The central arrangement of the camera operates to effect the carrying out of a trapezoidal filtering operation over antisymmetrically summed spatial signals through gated integration procedures utilizing idealized integrating intervals. By simultaneously carrying out peak energy evaluation of the input signals, a desirable control over pulse pile-up phenomena is achieved. Additionally, through the use of the time derivative of incoming pulse or signal energy information to initially enable the control system, a low level information evaluation is provided serving to enhance the signal processing efficiency of the camera.
