Abstract: The invention describes the preparation and use of fluorescent stains for nucleic acids derived from unsymmetrical cyanine dyes comprising a substituted benzazolium ring system linked by a methine bridge to a pyridinium or quinolinium ring system having at least one substituent that is a saturated or unsaturated cyclic substituent. Superior fluorescent characteristics when complexed with nucleic acids give the dyes utility for the detection of oligonucleotides and nucleic acids in cells, gels, and solutions. The presence of the cyclic substituent results in improved permeability in a wide range of cells and gels, resulting in improved detection of nucleic acids. Combination with additional dyes permits analysis of cell membrane integrity, Gram sign, or cell structure and function.

Abstract: A hybrid type power source control system controls the output of a fuel cell, with disregard of the operation of the vehicle accelerator pedal, responsive to the detected amount of residual charge of the battery, which amount fluctuates as the vehicle travels. For example, the output of the fuel cell system 3 might be 3 kW when the residual charge is from 70% to 90%, 5 kW when the residual charge is from 70% to 60% and 10 kW when the residual charge is below 60%. Consequently, the fuel cell system 3 can generate power with an efficiency of from 30% to 33% and can charge the battery 1 effectively. Because the output of the fuel cell is fixed for each of the rather broad ranges of residual battery charge, thermal fatigue of the fuel cell is prevented because of little output fluctuation. When the electric motor is continuously operated, the fuel cell continuously charges the battery to maintain a fully charged stated, optionally with some allowance for fluctuation thereof. When a fixed charge time is manually input, the output of the fuel cell is selected to fully charge (90%) the battery during the time selected.

Abstract: A frequency synthesizer (107) utilizes a variable oscillator (114) the output of which is used as the frequency synthesizer output (115) and is fed to a digital divider (108). The output of the digital divider (108) feeds one input of a phase comparator (109). The other input of the phase comparator (109) is fed from a reference oscillator (116). A phase comparator (109) output controls the variable oscillator (114). The digital divider (108) has a division ratio that is varied with time by a multi accumulator fractional N  division system (112) such that the effective division ratio may be varied by non-integer steps. Due to the time varying division sequence applied to the digital divider (108) there is a residual spurious level on the output signal (115). A second digital sequence from the multiple accumulator fractional N  division system (112) is generated to reduce this spurious level and is applied to the output of the phase comparator (109).

Title: A low nitrogen oxide combustion apparatus and method
Inventor: NAKAMACHI ICHIRO
IPC: F23D14/66
Filed: 1995-07-27
Granted: 2000-10-03
Abstract: The present invention relates to a low nitrogen oxygen regenerative burner, a regenerative burner system and a regenerative burning method. The low nitrogen oxide regenerative burner is comprised of one or more pairs of regenerators having a regenerating section inside and air supply and exhaust ports which open directly into a furnace; and one or more fuel injection nozzles for each of the air supply and exhaust ports, which also open directly into the furnace at locations apart from the corresponding air supply and exhaust port. The regenerative burner system consists of a furnace body, the low nitrogen oxide regenerative burner and a control means. The regenerative burning method is the process whereby air is preheated in the regenerator, injected from the air supply and exhaust ports of the regenerators into the furnace, fuel from the fuel injection nozzles located apart from the air supply and exhaust ports, is injected. The air and fuel form respectively independent jets, and suck large amounts of the inert gas filling the furnace as the combustion product, to be mixed with it, before they are mixed with each other to initiate burning. After the air and fuel have been sufficiently diluted by the inert gas, they are mixed with each other for burning. Slow burning occurs at a low oxygen concentration, and the existence of a large amount of the inert gas can keep the flame temperature low, all of which effectively inibit the formation of thermal NOx.

Title: Modified plastic bottle injection blow-molding apparatus and process
Inventor: SALEMI TONY
IPC: B29C33/30
Filed: 1995-09-26
Granted: 2006-05-16
Abstract: In an injection blow-molding process the preform is purposely formed as a smooth walled tube closed at one end and without any thread or other cap attachment configuration about the mouth of the preform. The preform is moved to the bottle mold which completely forms the cap attachment configuration with the bottle in the blow-molding step. A processing dome is also formed from the preform in the blow-molding step to provide means to transfer the bottle to the trimmer which removes the dome. By using the smooth walled preform (without threads or any other cap fastening features), the bottle mold may utilize only a portion of the vertical height of the preform for the bottle. Bottle molds for a variety of bottle volumes and heights may employ the same preform and preform injection mold. The smooth walled preform also permits bottle molds with a variety of mouth diameters to be employed with the same preform injection mold. Since the bottle mold provides the specific cap attachment configuration of the bottle such as threads or lugs, the same preform and preform injection mold may be employed for a variety of cap attachment configurations, by using a common preform only the bottle mold need be manufactured for each new bottle configuration thereby saving the cost of a dedicated preform injection mold and the cost of set-up time for the preform injection mold. The bottle molds can comprise sets of modular mold parts for exchangeability. For an injection blow-molding machine that is to be employed to manufacture several different bottle configurations on a batch basis each year the savings in tooling cost are considerable and the savings in set-up costs, processing time and minimum product rejects with the new process and apparatus can also be considerable.      The new smooth-walled preform and preform injection mold apparatus and process is also applicable to the injection, stretch and blow-molding process for making bottles.
