Granted: 2000-05-16
Abstract: Disclosed is a process of producing an optical fiber preform having a step of charging a feedstock gas in an oxygen-hydrogen burner via an electrode and hydrolyzing the same in an oxygen-hydrogen flame to produce particulates containing charged glass particulates and a step of blowing the charged particulates onto a target comprised of a seed rod or a soot body formed on the seed rod so as to cause them to deposit on the target and build up as a soot body. Preferably, the process includes the further step of reducing the magnitude of the charge of the particulates in the burner along with an increase of the diameter of the target Which is formed. More preferably, the process also includes the further step of making the position facing the burner across the target an opposite polarity from the charging polarity of the particulates ejected from the burner so as to electrically attract the particulates ejected from the burner.

Abstract: A transplanting tool for the manual extraction and planting of seedlings.  The transplanting tool comprises, a digging tube,  a hollow plunger slidably contained within said digging tube, a stem and a transverse piece forming a handle, and a pair of foot bars extending from the outside surface of said digging tube, at substan-tially  opposite  direction  from  one  another.    The arrangement of the components therefrom, offers a clear line of sight at the center of the hollow plunger for placing the digging tube over a seedling without damaging the plant's foliage.   The angle of the foot bars is adapted to prevent strain on the user's leg, thereby facilitating altering between digging and walking motion. The transplanting tool is therefore especially suitable for extracting seedlings from rough terrains.

Abstract: The present invention provides a staple cartridge assembly (10) adapted for use in a surgical stapler having a cartridge ret-ention portion (12) and an anvil (40) portion which are movable between a closed position and an open position. The cartridge assembly (10) comprises: a firing assembly for firing staples which is movable between a pre-fired and a fired position; a safety member (110); a mechanism mounting the safety member on the cartridge assembly (l0) for movement between a free-movement position which affords movement of the cartridge retention portion (12) and the anvil (40) portion between the open and closed position and a blocking position which prevents the cartridge retention portion (12) and the anvil (40) portion from being moved to the closed position; and a mechanism for releasably retaining the safety member (110) in the free-movement position and for releasing the safety member (110) to afford movement of the safety member (110) toward the blocking position when the firing assembly is moved from the pre-fired to the fired position such that upon movement of the cartridge retention portion (12) and the anvil (40) portion to the open position, the safety member (110) prevents the cartridge portion (12) and the anvil (40) portion from thereafter being moved to the closed position while the stapler is loaded with the spent cartridge.

Granted: 1997-03-25
Abstract: This invention relates to a marine vessel hull form, in particular to a high speed planing boat. It describes a new and distinctive shape of hull which, unlike other hull forms developed to date, features the shape which modifies the flow of water underneath and around it in such a manner that the waves behind the hull at speed are reduced to a minimum. This hydrodynamic effect results in reduced resistance and thus increased speed and / or reduced fuel consumption. Further, it will result in reduced wash behind the boat, an effect that will enable it to operate at full speed near shores where local regulations limit crafts' speed because of shore erosion caused by waves generated by boats and ships. The hull form described in this invention offer more stability than the traditional hulls do, due primarily to higher beam to length ratio and to the stern shape, which departs from the traditional "V", which is not particularly stable at speed or stationary.

The base station has metering means (13) for metering charge units accrued during the call between the base station and the handset.  Means (14) are provided at the base station for automatically generating a new over-the-air registration sequence to be sent to the handset in response to the metering means and transmitting (16) the new over-the-air registration sequence to the handset and replacing the number stored in non-volatile memory with a new number dependent on the new over-the-air registration sequence.  The new number differs from the old number to reflect deduction of pre-paid charge units.

Granted: 1998-11-17
Abstract: Two wide dynamic range detection circuits are disclosed, which are capable of detecting low-level desired signals in the presence of nearby strong interfering signals.          Each circuit includes an attenuator scheme for attenuating the interfering signal while passing the desired signal.  The first attenuator scheme uses a YIG filter in combination with an automatic gate arrangement.  The second attenuator scheme uses a two-channel arrangement.  The first channel uses a chirp-Z processor to derive a pulse-type transform signal in response to the strong interference signal.  The second channel includes a YIG filter followed by a programmable notch filter which is controlled by the interference-signal pulse from the first channel.  Following the programmable notch filter in the second channel is a chirp-Z processor followed by a gate arrangement wherein the gates are switched "OFF" under control of the interference-signal pulse from the first channel.

Granted: 1999-03-30
Abstract: An apparatus for automatic performance of temperature cycles in a number of test tubes in which each test tube is closed by a closure and contains a predetermined volume of a liquid reaction mixture. The apparatus includes a holder, a computer-controlled automatic control system, and a device for cyclic alteration of the holder temperature. The holder has an arrangement of chambers for holding test tubes with each chamber being adapted to receive one test tube. The holder is constructed of a material of high thermal conductivity, and has an upper surface, a bottom surface and a cylindrical outer wall. Each chamber has an opening located in the upper surface of the holder. The device for cyclic alteration of the temperature of the holder is actuated by the automatic control system. By reducing the dimensions of the device and the power required to operate it, numerous advantages are realized. Such advantages are achieved through the arcuate arrangement of chambers in the holder, and the test tube closure which is piercable by a pipetting needle.

Granted: 2006-04-11
Abstract: A target-specie responsive regulation of water treatment agent feed is achieved by the monitoring of a subject target-specie indicator. A target specie in a sample taken from the system is selected as the subject target-specie indicator, or instead an incipient reagent is added to the system sample to form a subject target-specie indicator. Such a formed subject target-specie indicator comprises a combination of the incipient reagent and a target specie. The subject target-specie indicator might then monitored by fluorescence analysis of the sample to determine at least one fluorescence emission value that can be correlated to the in-system concentration of the target specie. In combination with an inert tracer, the system consumption for the target specie can be determined. A responsive adjustment of the in-system concentration of a water treatment agent can be made.
