Title: Mixing an additive into a liquid supply
Inventor: MCLACHLAN WALTER S
IPC: G05D11/00
Filed: 1990-04-04
Abstract: MIXING AN ADDITIVE INTO A LIQUID SUPPLY          ABSTRACT OF THE DISCLOSURE         A dispensing system for introducing an additive into a liquid supply comprises a T-fitting which can be connected into the liquid supply line.  The T-fitting has at the bottom end of the leg of the T a female screw cap for attachment to the upper end of a plastic bottle con-taining an additive preferably in paste  form.   A dam member extends across the T-fitting so as to divert some or  all  of  the  liquid running  through  the  horizontal channel downwardly through the neck of the bottle for injection into the bottle so as to cause a dissolving action with the additive within the bottle.  The channel includes the first portion for injecting the liquid down-ward into the bottle and the second portion on the other side of the dam member for returning the liquid to the channel of the T-fitting downstream of the dam.   The second portion includes openings adjacent to the top of the container.  This system provides a simple yet effec-tive technique for applying an additive such as fertiliz-er into a liquid such as water supply for spraying of the mixture for example in lawn care systems.

Title: Synthetic equivalent test circuit of circuit breaker
Inventor: SATOH MINORI
IPC: G01R31/327
Filed: 1990-09-19
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a synthetic equivalent test circuit that can generate a 4-parameter TRV, for verifying a large current breaking performance of a power circuit breaker.  An inherent current source current is supplied to the testing circuit breaker to be tested and an auxiliary circuit breaker.  A small current, relative to the current source current is supplied to the first and second auxiliary switches from a power source.  In a state in which the small current from the current source or the resonance circuit flows, the first auxiliary switch is opened almost simultaneously with the auxiliary circuit breaker, the testing circuit breaker, and the like and operates so as to break the current at the time point of the final zero point of the current source current.          Therefore, the connection of the voltage source circuit just before the final zero point of the current source current, that is, the current supply of the voltage source current and the breaking of a capacitor circuit current by the first auxiliary switch to generate a 4-parameter TRV after that can be also easily accomplished.  Since a large current is not supplied to the first auxiliary switch, its electrodes and the like are consumed at a reduced rate.          Thus, the extremely stable operation can be continued for a long time without any inspection and maintenance.

Title: Pyridine-containing alkoxysilanes bonded to inorganic supports and processes of using the same for removing and concentrating desired ions from solutions
Inventor: BRADSHAW JERALD S
IPC: C07F7/18
Filed: 1990-10-31
Abstract: A method is disclosed for removal and concentration of desired transition metal ions from a source solution which may contain larger concentrations of other metal and H+ ions. The method comprises bringing the source solution into contact with a compound comprising a pyridine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The pyridine portion(s) of the compound has an affinity for the desired metal ions to form a complex thereby removing the desired metal ions from the source solution. The desired metal ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired metal ions than does the pyridine ligand portion of the compound. The concentrated metal ions thus removed may be recovered by known methods. The process is useful in removing unwanted metal ions from water streams and in the treatment of waste streams such as those containing metal ions from emulsions found in the treatment of photographic and x-ray films. The invention is also drawn to novel intermediates comprising pyridine containing ligands covalently bonded through a spacer grouping to a silane and to the final compounds formed by reacting the intermediates with a hydrophilic inorganic solid support material.

IPC: G03G15/32
Filed: 1991-04-15
Abstract: ABSTRACT        This invention involves both a process and apparatus for printing an image on a removable thicker dielectric layer  than  conventionally  used  in other  systems.   The process and apparatus can have one or more image-toning stations on a conductive substrate.  When multiple stations having  separate  imaging  and  toning  means  are  used, complicated image registration structures are avoided.  The dielectric layer used is at least 0.2 mils thick and is removed  from  the  system  after  it  is imaged,  developed, fixed and laminated or overcoated with a layer of the same family resin as used in the dielectric layer or layers.          The  imaged  and overcoated  layer  may  be  attached  to substrate such as a tile or wallpaper base, either before or after the process of this invention is completed.  The overcoating substantially strengthens the dielectric layer in addition to overcoating the image.   The final colored image  (or  monochrome)   is  removed  from  the  printing apparatus after the overcoating is laminated thereon.

Abstract: A plasma arc cutting torch 10, particularly one operating in the 0-200 ampere range, has a shield 38 mounted at its lower end adjacent a workpiece 26 to block splattered molten metal 26a from reaching a nozzle 16 of the torch.  The shield 38 is electrically insulated, preferably by mounting it on an insulating ring 22 that is itself secured on a cap 20 screwed onto the torch body 12.  A secondary gas flow 48 through the torch passes through the space 40 between the nozzle 16 and the shield 38 to provide cooling. Bleed ports 44,44' in the shield allow an enhanced flow rate with the remaining flow being at a rate, in conjunction with the size of an exit orifice 42 in the shield, to stabilize the plasma arc.  The bleed ports 44,44' are outwardly angled away from the arc.  Canted ports in the secondary gas flow path, but before the bleed ports, produce a swirling of the gas flow which enhances the quality of the cut.  A flow control system 60, preferably one utilizing parallel branch conduits and control valves, allows the selection of flow rates for the secondary gas depending on the cutting conditions.
