Abstract: An apparatus and method which enables a weapon (usually on a test firing range) only when the weapon is aimed at a predetermined zone around a target. A transmitter subsystem comprising a strobe light, power supply and alignment scope is disposed at or near the target and oriented so as to transmit strobe light pulses of preselected pulse frequency, pulse duration and spectral content at a receiving subsystem. The receiving subsystem disposed at or near the weapon optically focuses the received strobe pulses on a detector, which provides electrical signals in accordance with the received pulses. These electrical signals are processed by detector electronics so that an enable signal is provided to the weapon only when a pair of pulses is detected within a preseslected time interval. In this way, the present invention prevents unwanted firing of the weapon when it is not properly aimed at the predetermined zone.

Abstract: A bearing for a ball-shaped gimbal ring of a gimbal system has opposing arcuate tracks mounted individually to a gimbal ring and a base of the system. In a first embodiment, a ring track is segmentally opposed by a base track. Balls are disposed within the ring track and are kept there by a cage and retainer. A second embodiment includes a gimbal ring track that is fully opposed by the base track. Caged balls partially fill these tracks so that the balls are constantly opposed by the tracks in spite of differences in track and ball speeds.

Abstract: This disclosure pertains to an electrodeposited chromium composite having ternating layers of high contraction and low contraction chromium. The laminated composite properties are enhanced because of thin layers of the same metal existing under different states of hardness, stress, orientation and microstructure. Thin layers of HC chromium are produced with a random orientation, low residual stress, and crack-free structure. The alternating LC chromium layers tend to duplicate the random structure of HC chromium through epitaxial growth. Accordingly, crack-free laminated chromium are produced having hardness values ranging from 655 to 1084 Knoop Hardness Numbers. By comparison, conventional high-contraction chromium shows hardness values between 1000 and 1100 KHN. However, the latter deposits are invariably micro-cracked.

Abstract: The present invention involves labeling monoclonal antibodies with intermediate half-life radionuclides which decay to much shorter half-life daughters with desirable high energy beta emissions. Since the daughter will be in equilibrium with the parent, it can exert an in-situ tumoricidal effect over a prolonged period in a localized fashion, essentially as an "in-vivo generator". This approach circumvents the inverse relationship between half-life and beta decay energy. Compartmental modeling was used to determine the relative distribution of dose from both parent and daughter nuclei in target and non-target tissues. Actual antibody biodistribution data have been used to fit realistic rate constants for a model containing tumor, blood, and non-tumor compartments. These rate constants were then used in a variety of simulations for two generator systems, Ba-128/Cs-128 (t.sub.1/2 =2.4d/3.6m) and Pd-112/Ag-112 (t.sub.1/2 =0.9d/192m).

The resistor is formed and annealed prior to deposition of metal, e.g. aluminum, on the substrate.

Abstract: A composite target for an X-ray tube has a graphite substrate portion and a metal portion, the two portions being bonded together by successive interspersed layers of platinum and tantalum. The platinum layer is disposed between the graphite substrate portion and the tantalum layer. The tantalum layer acts to bond the metal portion to the platinum layer and also acts as an isolator to prevent the formation of carbides by migration through the bonding layers.

Abstract: Sets of group-complementary code arrays which have the property of being ually orthogonal over a subinterval of their total cross-correlation function have been identified. These group-orthogonal arrays are generated by a multiplication operation upon a given group-complementary array using a matrix which has diagonal elements from vectors which are orthogonal. Composite code arrays are synthesized by interleaving rows from the group-orthogonal set of arrays, and applying the resulting rows of codes to bi-phase modulate pulses in bursts. The resulting composite waveform has the desirable property of temporal (zero-Doppler) sidelobe cancellation in the maximum unambiguous range interval and response cancellation over one or more multiple-time-around range intervals of an equivalent uncoded pulse sequence.

Abstract: This invention relates to a new and distinct variety of pear tree which is useful as a size-controlling rootstock. The new variety originated as a single seedling selected from a large group of pear seedlings which were grown from open-pollinated seed. This seed was collected from Old Home Pear Trees (Pyrus communis) growing in an isolated planting with Farmingdale pollinizers. Pear fruiting varieties propagated on the under stock of this new rootstock variety are approximately 80% of the size of like pear trees growing on domestic Bartlett seedling rootstocks. This "semi-dwarfing" selection is easily asexually reproduced; particularly by hardwood cuttings. It has proven to be graft compatible with all commercially grown pear varieties. It was selected for its non-rootsuckering habit, its resistance to Fireblight disease and its tolerance of Pear Decline disease. It has also proven to be hardy, early bearing and well anchored in the many areas and soil types where it was tested.

Abstract: The present invention relates to a clingstone nectarine tree and more particularly to a new and distinct variety broadly characterized by a medium size, vigorous, very productive and regular bearing tree, the fruit of which ripens approximately the last week of August. The variety has a more exceptional red blush skin coloring at picking time than most other late varieties and is of outstanding firmness. This extreme firmness allows for an extended harvest period with more opportunity for the grower to consider market developments before picking. The variety was developed from a second generation seedling of a cross of Red Diamond (U.S. Plant Pat. No. 3,165) seed parent by Autumn Free (U.S. Plant Pat. No. 2,976) pollen parent. The original seedling was transplanted in 1981 and has been asexually reproduced by budding and grafting, and such reproduction of plant and fruit characteristics were true to the original plant in all respects.

Abstract: Electrical stunning apparatus for beef cattle or other livestock uses head restraining means to hold the animal's head in place during contact by electrodes. The animal's head is prevented from moving upwardly by a pusher which contacts the top of its head or neck, while a chin lifter moves in from below the animal's head to hold it in place. An electrode on the chin lifter contacts the animal's nose allowing a stunning current to pass through the animal's head to another electrode on the pusher (for head stunning). If deep stunning is required an additional electrode may be moved into contact with the rear of the animal to apply a heart-stopping current.

Abstract: An apparatus for reducing pressed fiber bales arranged in a row is disclosed which facilitates removal of fibers from the upper surface of the bales adjacent a stationary member (28). Transversely extending rollers (18, 19) parallel to milling rollers (4, 5) are provided with blocking means (25, 26). These blocking means may be actuated to prevent rotation of rollers (18, 19). As rollers (18, 19) are carried by housing (2) so as to extend slightly beyond the housing in the direction of travel (16). Upon reaching stationary member (28), blocking means prevents rotation of roller (19). The teeth of roller (19) act as a rake to remove fibers from bale (24a) adjacent stationary member (28) as reducing means (1) starts its travel in the return direction. In this manner, the fibers from the entire upper surface of bale (24) are more totally and uniformly removed.
