Abstract: APPLICATION OF             J. R. MALLOY AND A. M. OLSEN           A METHOD OF DIGITAL PROCESS VARIABLE TRANSMITTER CALIBRATION AND A PROCESS      VARIABLE TRANSMITTER SYSTEM      UTILIZING THE SAME              ABSTRACT     A method of digital process variable transmitter calibration includes the steps of sensing the process variable (PV) to produce an analog output which is converted to a digital signal representation.  The digital signal  is corrected by a microprocessor using a characterization equation previously individually developed during a manufacturing testing of the process variable transmitter over a predetermined range of environmental stimuli to ascertain the coefficients for a polynomial  in the form of PV = Ao + A1P + A2P2 +...AiPi.        Thus, the digital computer produces a process variable representation as a modified digital output.          Subsequently, the digital output from the computer is converted to a conventional 4-20 mA analog signal for use as a process control signal.  The process variable transmitter apparatus utilizing the aforesaid method includes means for receiving an output from a process variable sensor, an analog-to-digital converter for converting the received output from the sensor to a digital representation, a digital computer, a non-volatile memory for storing an individualized correction equation determined during the manufacturing testing of the transmitter and a digital-to-analog converter for converting the computer output to an analog control signal.

Abstract: Abstract of the Disclosure A method of manufacturing hollow metal sheet con-tainers and the containers produced thereby, comprising forming an annular edge roll extending radially outward at the upper end of the container, and folding the upper end outwardly so as to form an external pocket in which the edge roll is disposed. The ends of a flexible handle are inserted into this pocket at opposite sides of the container.          This  pocket is shaped to form an upper hollow reinforcement rim having an upwardly concave recess to receive a lid rim.          The sheet metal container thereby produced comprises a partia-lly hollow looking rim projecting outward and integral with the side wall of the container body and formed by at least three folded sections. The rim has retaining lips projecting radially inwards for the retention of the periphery of a lid on the container.  These lips are bent in from a double thickness of the sheet materials the outer  side of the upwardly concave recess, between those lips, being in the form  of upstanding partial cylindrical portions.

Abstract: ABSTRACT OF THE DISCLOSURE     An electro/hydraulic system for controlling remotely located valves or other types of hydraulically powered equip-ment.  The electrical system uses multiple microprocessors to send, validate, and execute commands.  Microprocessors at the central control station constantly communicate with and monitor similar microprocessors at remote locations.  The validation of commands increases safety and reliability of the present invention as compared to direct electrical control systems.          The electrical components of the present invention greatly decrease the lapse time between initiating a command at the central location and equipment response at the remote location.          The system also monitors and displays temperature, pressure, and valve position.

Abstract: Abstract of the Disclosure -A portable machine for electric arc welding and air carbon arc gouging on vertical wall surfaces is disclosed.  A table-mounted carriage arm carrying a vertical positioning assembly for welding nozzles or a gouging torch is driven horizontally around a vertical axis of rotation while guide wheels on the carriage arm traverse the wall surface or traverse a flexible guide secured to the machine table through a system of support arms when a rough wall surface is involved.  The carriage arm is biased yieldingly toward the wall surface during its horizontal traverse and the vertical positioning assembly adjusts itself automatically on its vertical axis to maintain proper welding nozzle and gouging torch alignment with the wall surface undergoing repair.  A constant speed of movement of welding nozzles or a gouging torch across the wall surface is maintained.  The welding nozzles or gouging torch are motor-driven vertically on the positioning assembly.

Abstract: -15-ABSTRACT PROGRESSIVE SCAN TELEVISION RECEIVER WITH ADAPTIVE MEMORY ADDRESSING A video input signal (S2) is stored in a memory (24) and read twice during a line-interval to provide a processed video output signal having a doubled line rate (2FH) for display on a display device (18) having a doubled horizontal sweep rate (2FH) thereby providing a progressively scanned image having reduced visibility of line structure. The last address written in memory is used to control the starting time of the second memory read operation This reduces the tendency of visible artifacts to occur in cases where the video input signal is "non-standard" in the sense that the ratio of the color subcarrier frequency with respect to the line rate is such that there may not be a fixed number of color subcarrier cycles per line.

Abstract: ABSTRACT                  STUDS FOR FOOTWEAR      It  is  known  to  provide  studs  having  externally screw-threaded spigots (6) which are screwed into sockets (21) provided in the soles (31) of articles of footwear. In use,  lateral  forces applied to the ground-engaging portion (3) of such a stud tend to damage the associated socket,  particularly if the  socket  (21)  is made of a plastics material.  To resist radially outward expansion of  the  socket  the  invention provides  retaining means spaced outwards from the spigot.  The retaining means may consist of a retaining ring  (16) with a flared bearing surface  (17).   The presence of the retaining means may render  a  split socket  usable;  also  it may assist  in preventing an otherwise loose stud becoming inadvertently unscrewed.

Abstract: Abstract Process For Removing Electrolyte Vapor From Fuel Cell Exhaust Gas Electrolyte vapor entrained in the hot exhaust gas stream from a fuel cell is removed by passing the gas stream through a saturator, over high surface area material, in direct contact with water circulating in a loop which also passes through the saturator.  The hot gas stream evaporates a small portion of the water, resulting in cooling of the gas stream and condensing of electrolyte therein as it cools.  The electrolyte dissolves into the recirculating water.  The water is exchanged at predetermined intervals or when the concentration of electrolyte reaches a predetermined level.  At least 99% of the electrolyte can be removed from the gas stream in this manner.

Abstract: Process for the preparation of pure dimethyl-sulphoxide (I) by dissolving technical-grade (I) in a first solvent, adding a second solvent, immiscible with the first, and extracting (I) with the second solvent. Separation of the 2 phases and distillation at a max. temp. of 108 deg.C gives the purified material.

In the latter case (I) acts as a transcutaneous carrier which increases the passage of the drug through the skin. Technical and partly purified (I) contains many impurities as well as aesthetically undesirable odour. The new process removes the odour as well as most impurities and provides a pharmaceutically acceptable quality.
