IPC: B01F1/00
Filed: 1994-07-25
Abstract: An apparatus (10) and a method for mixing or dissolving a particulate solid such as a granular chemical (12) in a liquid such as water (14) to form a liquid solution (16) of substantially homogeneous concentration. The apparatus (10) comprises a vessel (18) having an inlet (34) in fluid communication with an outlet (32). A conical frustum (24) is formed at its largest diameter end with the outlet (32). The smallest diameter end of the conical frustum (24) is downstream of the largest diameter end of the conical frustum (24). A suction line (26) connected at one end to the smallest diameter end of the conical frustum (24) is connected at an opposite end to a pump (28). A discharge line (30) is plumbed downstream from the pump (28) and connected to the vessel (18) at the inlet (34). The water (14) or solution (16) can be pumped from the outlet (32) through the conical frustum (24) and the suction line (26), by the pump (28), and discharged through the discharge line (30) to the inlet (34) and returned to the vessel (18) through a flow nozzle (22). The flow nozzle (22) comprises a tube formed in the shape of an elbow and is connected at one end to the vessel (18) at the inlet (34). The flow nozzle (22) is shaped to direct the water (14) or solution (16) in a direction which is substantially parallel to an inside surface of the vessel (18) adjacent the inlet (34) such that the water (14) or solution (16) is given a substantially circular flow (36). The method comprises recirculating water (14) through the vessel (18) via the conical frustum (24), the suction line (26), the pump (28) and the discharge line (30). The combined action of recirculation and the substantially circular flow created by the flow nozzle (22) and conical frustum (24) mixes or dissolves the granular chemical (12), for example, added to the water (14).

IPC: C12P21/08
Filed: 1994-08-05
Abstract: A monoclonal antibody which selectively binds to all forms of thymidine kinase, including TK2, active and inactive forms of TK1, and monomeric and multimeric forms of TK1, is described. Also described ate monoclonal antibodies which selectively bind only to active or tetrameric TK1 and to TK2, respectively.

Inventor: PASAD DILIP
IPC: D06F58/30
Filed: 1995-02-15
Abstract: An apparatus and method for applying textile treatment finishing agents to garments or garment work pieces is provided.  The apparatus includes a rotating drum (32) and a nozzle (15) for generating a fine mist or fog of textile treatment agents inside the rotating  drum (32).  The apparatus  can  be constructed as a dedicated  processing  machine, or a conventional,  industrial washer or dryer  can  be fitted with an appropriate nozzle (15) and feed lines (16, 19)  to  provide a dual  purpose machine which can be used for  its  originally intended  purpose, and can be selectively used for  applying  textile treatment agents.  Uniform coverage of the  surface of the garment is assured  by tumbling the garments through the fog  created by the nozzle means (15). By controlling the size of the  droplets, and the time during which mist  or fog is  generated, the amount of chemical agent  absorbed by the garments can be controlled.  The use of the finely divided, air dispersed liquid agent avoids wasted processing chemicals and permits the use of more  concentrated chemical agents.
