Abstract: Abstract of the Invention A one-piece T-shaped carton blank is disclosed which is utilized to form a rectangular cross-sectional container having its top and bottom end panels sealed in a plane substantially perpendicular to its sidewalls.  The carton blank is formed having a definite dimensional relationship between its end panels and side panels to provide improved nesting of multiple carton blanks upon paperboard sheet stock in an alternating inserted side-by-side relationship.  A pair of end sealing tabs extend along the top and bottom edges of the blank side panels.  One of the end sealing tabs is separated from the top end panel and from a side sealing tab to prevent tearing and to permit the complete welding of the side sealing tab up onto the top end closure panel of the carton blank.  This separation of the end sealing tab in combination with displacement of the hinge line of the top end closure panel downward provides a liquid-tight corner seal for the carbon.  Further, an improved method of scoring and bending of the carton blank is provided.

The system includes a chamber housing first and second electrodes disposed facing each other and spaced apart, each electrode extending substantially parallel to an optical axis of the chamber. A pulse producing circuit connected across the electrodes and has a switch device which, when connected across a voltage source, can be actuated to produce high voltage pulses between the electrodes. The system also includes a microstrip capacitor comprising coatings and a die-electric layer between the coatings, the coatings and dielectric layer extending substantially normally to the optical axis of the chamber and being stacked in a direction substantially parallel to the optical axis. The first electrode is connected to earth potential and the second electrode, facing the first electrode, is connected to one of the coatings of the microstrip capacitor. At least one of the coatings is provided with cut-away portions which increase the length of the current flow path for the discharge current which flows when the switch device is actuated.

Abstract: A B S T R A C T      Microbiological conversions of cyclodextrins are intensified by adding to the reaction mixture 0.2 to 3 moles of .alpha.-, .beta.- or .gamma. cyclodextrin or an optional mixture thereof pro mole of the steroid substrate, before, at the beginning or during the conversion.  The cyclodextrin if desired, can be recovered after the reaction.  In this way the reaction velocity can be increased, the reaction time is reduced, the substrate concentration in the solution, i.e. its solubility is increased or the so called product inhibition may be avoided.  In certain cases of more alternatives the desired reaction can be catalysed and in this manner the selectivity is increased.

Abstract: VERTICAL DRIP SEPARATOR APPARATUS AND METHOD                     A B S T R A C T         A system for preventing freezing of liquids during separation of liquids from natural gas at a natural gas well head comprising an elongated tank mounted in a vertical attitude with a lowermost portion buried in the ground below the frost line and an uppermost portion extending above the ground.  A divider plate separates the tank into an upper compartment and a lower compart-ment.  Each compartment has a liquid reservoir at the bottom thereof.  An underground natural gas supply line is connected to a mid-portion of the lower compartment whereby material gas including liquids such as water and hydrocarbons flows into the lower compartment.  The bottom reservoir portion of the lower compartment is connected to the bottom reservoir portion of the upper compartment by a vertical tube therewithin whereby liquids which accumu-late in the lower compartment reservoir are lifted through the tube to the upper compartment reservoir by pressure of the natural gas whenever the lower inlet end of the tube is covered by liquids in the lower compartment reservoir.  A heater device operated by the natural gas supplies heat to a housing surrounding the upper com-partment reservoir to prevent freezing of liquids therein which are periodically automatically removed therefrom whenever a predetermined maximum volume of liquids are accumulated therein.

Abstract: PHB. 32.960                   11 ABSTRACT:     In digitally encoded data transmission systems such as paging systems using a code word format, such as POCSAG, each code word includes a number of bits collec-tively termed the cyclic redundancy check bits.  In a paging receiver the cyclic redundancy check bits are used to determine if there are errors in the received message code words.  If an error is detected then one bit random error correction is generally applied because it has a more acceptable falsing rate compared to say two bit random error correction or four bit burst error correction.  In a POCSAG paging system deseribed as an example the option of one bit random error correction or 4 bit burst error correc-tion with additional protection against falsing is given. The additional protection is to include error detection check bits in the entire message which is transmitted by the base station without deteriorating the calling rate performance.  At the receiver any errors in the message code words are subjected to four bit burst error correction and thereafter the entire "corrected" message is subjected to a further check using the error detection check bits. Whether or not error detection check bits have been included in the message is indicated by preconditioning the message, for example by using predetermined ones of the plurality of addresses allocated to each pager for different purposes.

Abstract: ABSTRACT          The device comprises at least one nozzle (T), in combination with a regulating valve (VR).         A detector (135) measures the  flowrate  of  the fluid in the nozzle and controls a distributor (109)  for selecting a static pressure take-off orifice from amongst a plurality of regularly staged orifices in a  convergent section (101).         The orifice is brought into communication with a chamber (127) of the  regulating  valve to  control  the position of a closure member (119) which  uncovers  to  a varying degree the orifices of a cage (117).         The displacement of a distributor (121) from one position (R)  to  another  (S)  converts  the  regulating function into a shut-off function by pressure effect,  by applying a high pressure to the chamber (127).         The  total  immersion  of  the  closure   member obviates the disadvantages of the rod and packing  system of conventional valves, as well as those  resulting  from the radiation-sensitivity  of  the  prior  art  pneumatic servomechanisms.
