Abstract: An accumulating apparatus for a sheet-like negative film holder fed from a feeding section. The film holder is capable of holding a plurality of negative film strips as arranged along the lengths thereof. The apparatus includes a retaining section for retaining the film holder in a suspended state and having a pair of retainer units disposed adjacent the feeding section and arranged one after another in a direction of transporting the film holder for retaining a rear end of the film holder respecting its transporting direction, and a retaining section driver unit for selectively driving the pair of retainer units to a retaining position or to a non-retaining position. When the retaining section is about to receive the film holder from the feeding section, the retaining section drive means drives only one of the retainer units to the non-retaining position. Whereas, when the retaining section has received the film holder, the retaining section drive means switches over the one retainer unit from the non-retaining position to the retaining position and also switches over the other retainer unit from the retaining position to the non-retaining position.

IPC: B61F1/10
Filed: 1996-04-30
Granted: 2004-01-20
Abstract: An end structure for a railroad freight car having longitudinally extending and spaced apart side structures. Each of the side structures provide top and bottom longitudinally disposed structural members which are spaced apart and connected to the end structure. Each of the top and bottom members have a terminal end portion. The bottom member is shorter in length than the top member to define an overhanging relationship between the top and bottom members in an area of the end structure outboard of the terminal end portion of the bottom member. The end structure comprises a planar sidewall extending between the top and bottom members. The sidewall has top and bottom edges. The top edge is joined to the top structural member. The bottom edge consists of an inboard straightedge portion, an intermediate curved portion and an outboard straightedge portion. The inboard portion is joined along its length to the bottom structural member. The curved portion extends upwardly from the inboard portion adjacent the terminal end portion of the bottom structural member and merges with the outboard portion of the bottom edge of the sidewall. The curved portion defines a curved edge having a positive slope of constantly decreasing value when measured from the inboard portion to the outboard portion. Theend structure further comprises a one-piece curved flange connected to the terminal end of the bottom structural member and to the curved portion of the bottom edge of the sidewall along the entire length thereof. The sidewall consists of a single web in the area of the end structure outboard of the terminal end portion of the bottom structural member and inboard of the terminal end portion of the top structural member. The continuous curvature of the flange is designed to reduce stress risers associated with geometric discontinuity, to enhance fatigue resistance of the flange itself and the end structure, and to facilitate access by an operator to a truck supporting the end structure.

IPC: B29C43/00
Filed: 1996-12-24
Granted: 2006-03-21
Abstract: A rotational indexing base curve deposition array for assembling contact lens base curves and front curves with a prescribed and programmable angular orientation to produce a contact lens having a selected axis placement therein, such as a toric axis for a toric contact lens. An array of front curve molds are arranged in a support pallet with a dosed amount of monomer mixture deposited into each of the front curve molds. An array of deposition tubes, positioned in a support plate and coupled to a vacuum source, is used to pick up and support an array of base curve molds. Each of the deposition tubes is then angularly rotated in to the support plate to a selected angularly indexed position therein. A common angular rotational drive is coupled to each of the deposition tubes in the array to angular index each of the deposition tubes to a precise angular position in the support plate. The common angular rotational drive is driven by a stepper motor which can be controlled in a programmable manner to change the selected angularly indexed position. The stepper motor drives moveable racks, which drive pinion gears around the deposition gears. The angularly indexed array of base curve molds is then assembled over the array of front curve molds to produce toric lenses having first and second optical surfaces which are precisely angularly indexed relative to each other.

Patent CA-2206619-C (CA)
Inventor: RICE CHRISTOPHER W
IPC: H03G3/30
Filed: 1997-05-30
Granted: 2000-04-04
Abstract: A dual loop feed forward amplifier and method of amplification. The dual loop feed forward amplifier contains at least two amplification stages thatintroduce unwanted intermodulation products into the output signal. A spreading tone is introduced to the RF signal in between the first and second amplification stages. The spreading tone is created by a bi-phase modulator that spreads an input tone in accordance with a spread PN- code. After the spreading tone is amplified by the subsequent stages of the feed forward amplifier, the spreading tone is despread by the same spread PN-code. The resulting output tone is mixed with the originalinput tone. The output of the mixer is then filtered to remove the unwanted spurious products produced by the mixer. The feed forward amplifier is then actively adjusted by a computer controller to reduce any difference between input tone and the output tone until a desired signal-to-interference ration is obtained.

Title: Method of optimizing neighbor set during soft handoff of a mobile unit in a cdma cellular environment
Inventor: CHHEDA ASHVIN
IPC: H04W48/20
Filed: 1997-10-27
Granted: 2002-03-26
Abstract: System and method for optimally updating a neighbor set for use by a mobile unit during soft handoff of the mobile unit in a CDMA cellular telephone environment is disclosed. A two-step process is used to ensure that the individual neighbor sets of active set members are combined in a manner such that only pilots representing the more important sectors are included in the updated neighbor set and pilots representing the less important sectors are excluded therefrom. In the first step, active set members whose RTD is more than twice as great as an OWD threshold are eliminated from consideration. In the second step, the neighbor set of the mobile unit is updated using the sectors included in the individual neighbor sets of the active set members that were not excluded by the first step, wherein those sectors are included in the updated neighbor set according to the number of individual sets in which they are found and their priority within those sets. In an alternative embodiment, a combined carrier-to-interference ratio for each of the individual neighbor set members is also used in updating the neighbor set. In an alternative embodiment, the individual neighbor set of the active set member having the shortest RTD is used as the updated neighbor set.
