Abstract: A device for assaying biological fluids for molecules contained therein comprising a container, material situated in the container for absorbing fluid and in communication with an antibody or antigen impregnated matrix, wherein the matrix is accessible to the exterior of the container through a funnel-shaped aperture in the roof of the container.  Further features include a chemical drying agent associated with the container for absorbing moisture, thereby preventing inactivation of the assay reagents, and a filter situated above the antibody or antigen impregnated matrix, and in communication with the matrix through the aperture in the roof of the container.  The filter removes interfering substances present in the biological fluids, and provides protein blocking agents to the matrix material for decreasing the background of the assay.

Abstract: : When blanks for producing (cigarette) packs are made in the region of the packaging machine itself, especially by being severed from a web of material (12), the blank production must be matched to the performance of the packaging machine. For severing blanks (10, 11) from a web of material (12) having stampings, perforations, etc. drawing rollers (25, 26) and conveying rollers (33, 34), on the one hand, and tearing rollers (27, 28 and 35, 36) running at a higher speed, on the other hand are used. The blanks (10, 11) are torn off as a result of the difference in the conveying speed. In the simultaneous processing of two blanks (10, 11), units (23) comprising two blanks (10, 11) are first severed from the web of material (12) and these are then divided into individual blanks (10, 11) which are conveyed further, especially fed to a folding turret (20).

Title: Spontaneous reporting of remotely generated data
Inventor: BENNETT CHRISTOPHER J
IPC: H04M11/00
Filed: 1988-10-26
Granted: 1995-01-10
Abstract: A device for spontaneously reporting remotely stored data is coupled to a descrambler in an impulse pay-per-view television system for storing and reporting data pertaining to subject matter descrambled by the descrambler, suchas identification of each impulse pay-per-view program that is descrambled.  Thedescrambler receives scrambled television programs over a data link from a central station.  The reporting device is coupled to the central station by telephone lines for reporting the stored data to the central station.  The reporting device includes a memory at the remote location for storing the generated data; and a control unit for causing the stored data to be spontaneously reported in response to the storage of at least a predetermined minimum amount of data, independently of responding to an interrogation signal requesting the report.  The control unit includes a clock for indicating elapsed time; and the control unit processes theelapsed time indication to define time slots within which to make the reports, with predetermined time slots for the reporting of the stored data following the storage of at least the predetermined minimum amount of data being assigned by the control means in accordance with stored predetermined criteria.  The control unit monitors whether the stored data was successfully reported to the central station; and tries again to report the stored data when the stored data was not successfully reported to the central station.  Upon trying again the control unit causes the stored data to be reported in a different predetermined time slot than that used for the last previous unsuccessful report.

Title: Network and intelligent cell for providing sensing, bidirectional communications and control
Inventor: MARKKULA ARMAS C
IPC: G08C15/00
Filed: 1988-11-02
Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE              A network for providing sensing, communications and control is described.  A plurality of intelligent cells each of which comprises an integrated circuit having a processor and input/output section are coupled to the network.  Each of the programmable cells received when manufactured a unique identification number (48 bits) which remains permanently within the cell.  The cells can be coupled to different media such as power lines, twisted pair, radio frequency, infrared ultrasonic, optical coaxial, etc., to form a network.  networks are distinguished from one another by system identification numbers (IDs).  Groups of cells within each network are formed to perform particular functions and are identified by group IDs.   Communications occur within the network through use of the system, group and cell IDs.  Some cells (announcers) are assigned the task of sensing, for example, the condition of a switch, and others (listeners) the task of controlling, such as controlling a light.  Cells can perform multiple tasks and be members of multiple groups, and, for example, can act as a repeater for one group and a listener in another group.  When manufactured, the cells are identical except for the cell ID; they are programmed to perform specific tasks for a particular group or groups.  The network protocol provides great flexibility, and allows groups to be formed and/or changed after the cells are in place.

Title: Method of removing water soluble organics from oil process water
Inventor: BELLOS THOMAS J
IPC: B01D17/05
Filed: 1988-11-08
Granted: 1994-06-28
Abstract: ABSTRACT Oil well production fluid composed of oil and water and containing in excess of 100 ppm water soluble petroleum carboxylates in anionic form dissolved in the water is treated by acidifying the fluid to a pH of 6.0 or lower with a strong acid and then is intimately mixed. The oil and water are separated one from the other.  The content of the water soluble organics in the water is thereby substantially transferred to the oil phase.  In a second aspect of the invention, water used to extract corrosive compounds to render the oil suitable for fueling gas turbine power plants is acidified to a pH of 6.0 or lower and is thereafter intimately mixed with fuel oil.

Abstract: ABSTRACT          Apparatus is provided for the lifting of articles, especially tray packs.  The lifting and transportation of sensitive articles incapable of bearing a mechanical load, without manual involvement, presents special difficulties in packaging technology.  This applies, above all, to tray packs in which articles are arranged standing on a bottom part of small height, without any additional anchoring. For grasping and lifting articles of this type, there is provided a raisable and lowerable suction box which, with dimensions equal in a closed position to those of the pack, is placed over the pack in the manner of a bell.  By the generation of a vacuum within the suction box, the tray of the tray pack is held gently so that the pack can be lifted by means of the suction box.  Side walls of the suction box are pivotally actuated by means on top of the suction box, to make  it easier  to place the  suction box  onto the article,  and have flexible extension to enable them to reach down to and form a seal with the tray.
