Abstract: ABSTRACT     Milking machine methods and apparatus facilitating automatic attachment to the dairy cow's udder incorporate upstanding thin-walled flexible conical teat cup entrance portals, with the four teat cups preferably positioned upright in a trapezoidal configuration, free for lateral and longitudinal movement horizontally, while resisting vertical displacement. Leaf-spring retainer arms positioned vertically edgewise provide resilient adjustable teat cup positioning. A claw manifold guides milk received from the teat cups in laminar flow streams, minimizing foaming turbulence. A robotic manipulator may be used to attach these milking machines to the udders of a plurality of dairy cows.

Abstract: ABSTRACT OF THE DISCLOSURE          FEEDER FOR ANIMALS        A  feeder  for  cylindrical  bales  is of  the tombstone  type  that  is  it  includes  a  lower  circular  band defined by hoops and an upstanding sheet of material forming a skirt.  U-shaped frames or tombstones are then attached to the outer frame and extend upwardly therefrom with the animal able to reach between the tombstones for grasping feed from a bale confined within the feeder. In accordance with the improvement of the present invention, the tombstones are bent inwardly and upwardly so that the animals front legs ace confined outwardly away from the bale while the animal can reach over the inclined portion of the tombstone and through the vertical portion of the tombstone to the bale.   The animal is encouraged to feed within the outer frame and thus any waste is deposited within the outer frame and cannot be trampled or spoiled.  The animal is inhibited from pressing its shoulders against the frame thus reducing  damage  or  breakage  and  excessive  movement  of  the feeder.

Abstract: Abstract A  unique  housing  (104  and  600)  of  a portable radio transceiver (100) is described that takes advantage of the heat sinking, electrical shielding and structural  characteristics  of  a  battery.   The unique electronic circuitry housing  (104  and 600)  includes a battery  as  a  structural  element  thereof.    In  one illustrated  housing  (104),  a  stick  battery  (210)  is attached to the side of a transmitter printed circuit panel (213).  A logic printed circuit panel (212) and a receiver printed circuit panel (214) are positioned above and below the transmitter printed circuit panel  (213), respectively, and are held together by interlocking side rails  (206,  207). In  a  second  illustrated ;housing (600), a flat battery (602) is attached to the sides of a first U-shaped printed circuit panel (604).  A second U-shaped printed circuit panel (606) is positioned between the battery and the first panel (604).  Heat dissipated by the electrical components on the second panel (606) is conducted away by the flat battery (602).  The electronic circuitry housing  of  the  present  invention  may  be advantageously  utilized  in  a  variety  of  applications where electronic circuitry is operated form a battery.

Title: Electronic ballast for fluorescent lamps
Inventor: KRUMMEL PETER
IPC: H05B41/24
Filed: 1989-07-25
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE    Electronic ballasts are essentially composed of a series connection of a harmonic filter that has its input side connected to the AC  line,  a rectifier  and  an inverter to which is connected at least one load circuit composed of a  series circuit of  an inductor and a parallel circuit composed of a fluorescent tube and a capacitor.  When a high electric tolerance is required of such a ballast in view of a desired increase in the power  factor,  standard  circuit  designs  required  a relatively expensive storage capacitor that smooths the AC rectified line voltage.  In order to be able to use a storage capacitor that has a lower electric tolerance in comparison to the required voltage tolerance of the ballast, a storage capacitor is incorporated into one of the two capacitor branches of the inverter which is composed of a switch bridge arrangement having two switch branches  and  two  capacitor  branches,  this  storage capacitor being connected in series with the actual load.

Abstract: A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14). The cam ring and sector gear are rotatable in a substantially constant axial position. A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens. The zoom lens is movable between an extreme telephoto position and an extreme wide angle position, as well a into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position. When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge (4e) is pivoted into the path between a light receiver (4) and a light emitter (3e). A single cam plate (53) is provided to move the finder assembly and the strobe assembly. The photographic aperture (22b) can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position. A light intercepting assembly (210) is provided for preventing light from entering the photographic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.

Abstract: A battery cap having threads and bleeding means for controlled bleeding of generated gasses, comprise a threaded portion of the cap being radially devided into a plurality of equal parts (2, 3) the plurality thereby being a multiple of 4 and the threads of one part being axially offset by 1/2 lead in relation to the threads of the adjacent part. The battery cap according to the invention furthermore comprises a lip (7) being biassed against the underside of the cap flange (12), an annular chamber (15) thereby being created between the lip (7) and the underside of the cap flange (12). Furthermore a plurality of passages (6) extending from the annular chamber (15) to the interior of the cap. When the cap is presses into a hole in a battery cover, the parts (2, 3) of the threaded portion will give after successively until the cap is pressed down in such a way that the shoulder (16) is abutting against the battery cover. Hereby the threads of one part will mesh in the corresponding threads of the cover, whereas the tips of the threads in the other part, will be pressed against the tips of the threads in the cover. The cap thereby is retained in the battery cover. By generation of gasses from the inside of the cap, the increased pressure of the internal will be conducted through the passages (6) to the annular chamber (15) and the lip (7) will open at a predetermined pressure. The lip (7) avoids dust and water in penetrating into the cap interior and the lip together with the passages (6), which have a minimum cross section, will make the battery cap fire retardent.
