Abstract: A package for an elongated object such as a flashlight consists of a front panel and a rear panel, with two or more spaced V-shaped ribs being formed in the front panel. One end of the object is engaged with a first one of the ribs, and the opposite end of the object is engaged by the second one of the ribs in a manner such that the portion of the object between the ribs is ex-posed. Openings are formed in the walls of the front panel defining the ribs, and are configured in a manner so as to positively retain both ends of the object in position relative to the ribs once the front and rear panels are secured together. The package further includes a third rib spaced from one of the first or second ribs. Openings are formed in the third rib and the adjacent rib so as to receive end package objects such as batteries for the flashlight in a manner such that a portion of the length of the batteries is exposed between the ribs.

Title: Circuit for driving the excitation coil of an electromagnetically driven reciprocating pump
Inventor: HEIMBERG WOLFGANG
IPC: F02N19/00
Filed: 1993-03-04
Granted: 1999-06-29
Abstract: The invention pertains to a fuel injection device operating according to the solid-state energy storage principle, whereby a rotor element carried in a pump housing of an electromagnetically driven reciprocating pump is accelerated almost without resistance, whereby the rotor element stores kinetic energy and impacts on a piston element, so that a pressure impulse is generated in the fuelcontained in a closed pressure chamber before the piston element due to the fact that the stored kinetic energy of the rotor element is transferred via the piston element to the fuel in the pressure chamber and whereby the pressure impulse is used for the injection of fuel through a nozzle and whereby the rotorelement is carried form-locking on the piston element and the two elements are mutually spring-mounted.

Title: Transfer mechanism for web winding device
Inventor: KREMAR DJURO
IPC: B65H19/22
Filed: 1995-02-24
Granted: 2005-04-26
Abstract: There is disclosed a web winding device for winding a substantially continuous web onto a rotating reel bar. The winding device includes a driving drum having an axis about which the drum is rotated. The driving drum maintains a nip driving engagement with the reel bar to rotate the reel bar and transfer the web passing over a surface of the driving drum onto the reel bar. The winding device further includes a transfer mechanism for moving the reel bar from a primary winding position where the web is initially wound onto the reel bar to a secondary winding position while maintaining the reel bar in nip driving engagement with the driving drum. The transfer mechanism includes rotating transfer arms mounted to rotate about an axis aligned to the axis of the driving drum. The rotating transfer arms support movable supporting jaws adapted to secure the reel bar and support the reel bar as it moves from the primary winding position to the secondary winding position. The transfer mechanism further includes actuator apparatus comprising movable linkage and rotator apparatus. The movable linkage interconnects the rotator apparatus to the rotating transfer arms. The rotator apparatus rotates a predetermined angular amount at a predetermined rotational velocity to cause the linkage to move and control the rotation of the rotating transfer arm about the axis of the driving drum. By providing linkage and a rotating machine of limited rotation, the present invention eliminates the use of a gear wheel rack and pinion and the associated problems that occur as the teeth in the gears wear out.

Abstract: In a method for detecting leakage in a pipetting apparatus, the inner pressure of the pump connected to the nozzle tip is measured to discriminate the presence of leakage objectively.        In step 202, distilled water 90 is aspirated.      When the inner pressure P1 of the pump after aspiration is roughly equal to the atmospheric pressure, a leakage is determined. Further, in step 203, after the inner pressure P1 of the pump has been measured after aspiration in step 202, the tip 36 is kept stopped for 30 sec, for instance without raising the tip, and the inner pressure P2 of the pump is measured again by the pressure sensor. When this inner pressure P2 is different from the inner pressure P1 previously measured, a determination that there is a leakage is made. Further, in step 204, aspirated distilled water 90 is dispensed into the same test tube 62. The inner pressure of the pump is kept monitored by the pressure sensor. In this case, when the pressure changes abruptly, a determination that there is a leakage is made.     The leakage detection is completed at the time whenever the leakage is detected.

Abstract: An electrophoretic display (10) includes a laminated triple pane construction with an    electrophoretic fluid-containing  envelope (24) formed between the first and second panes (12, 14) and an ionizable gas-containing envelope (26) between the second and third panes (14, 16). A transparent reference electrode (20) coats the first pane internal to the fluid envelope. A matrix of discrete pixels are disposed upon the second pane (14) within the fluid envelope (24). Each pixel has a probe (30) extending therefrom through the second pane (14) and into the gas envelope (26). A plurality of row electrodes (32) are disposed upon the second pane (14) in the gas envelope (26) in close proximity to corresponding rows of probes (30). A plurality of column electrodes (28) disposed upon the third pane (16) within the gas envelope (26) perpendicular to the row lines (32) establishing an addressable X-Y matrix.  By impressing a sufficient voltage differential at selected intersections of the matrix, a local ionization of gas biases a proximate probe to the ionization potential. The probe potential is shared by the corresponding pixel, setting up an electrostatic field relative to the reference electrode (20) for controlling the movement of pigment within the fluid.

Abstract: L'invention concerne des verres d'halogénure particulièrement utiles en tant qu'hôtes de métaux de terres rares de manière à produire une amplification optique par activité laser. Lesdits verres se caractérisent par une teneur en métal similaire à celles des verres ZBLAN, avec la différence, toutefois, que le remplacement d'Al par Y et In et l'utilisation de plus d'un fluorure de métal alcalin tel que NaF, CsF et LiF leurs confèrent des propriétés synergiques. Ces propriétés synergiques se manifestent par de bonnes performances de lasage (grâce à la faible teneur en aluminium) et de stabilité (malgré la faible teneur en aluminium). Pr3+ constitue une bonne espèce de lasage pour l'amplification de signaux de télécommunications de 1300 nm avec un rayonnement pompé à 1020 nm.
