Abstract: Apparatus and method for thickening a suspension of pulp in liquid employs three rolls (20, 22, 25) arranged in spaced relation with their axes defining a triangle, and a single loop of wire (30) is trained around and in wrapping relation with all three rolls. The first and third roll have a headbox (40, 45) which delivers a flow of the suspension to be thickened in such manner that it is trapped between the wire and the portion of the roll wrapped by the wire so that the trapped suspension is dewatered and concentrated by expression of liquid through the wire. The pulp deposited on the inside of the wire at each of the positions comprising a roll and headbox is collected from the surface of the second roll (22) and is transported out from within the triangular space within the wire loop. In one embodiment, the roll at each roll-headbox station has a grooved surface such that it forms separate strips of pulp on the wire, and the next roll downstream therefrom has a similar grooved surface offset axially from the preceding roll so that it causes strips of pulp to be deposited on the wire between the strips produced by the previous roll.

Abstract: A method and apparatus for performing SRT division, in which Gray coded quotient bit signals are generated during each iteration from a divisor signal having Gray coded bits, and a dividend signal. Preferably, only the two most significant bits of the divisor signal are encoded into Gray code at the start of the division process, and the Gray coded quotient bit signals are decoded after each iteration, or after the final iteration, for use in generating the final quotient. In a preferred embodiment, the invention is a circuit capable of performing both single-precision and double-precision operations, and includes a pair of alternately operating divider block circuits each for generating a pair of quotient bits during each iteration cycle. The quotient bits emerging from each divider block circuit are decoded, and then shifted into one of two divider result registers depending upon their sign until 56 quotient bits (for double-precision operation) or 28 quotient bits (for single-precision operation) are accumulated in the divider result registers. When sufficient quotient bits have been accumulated, the invention asserts the contents of the divider result registers, a remainder sum register, and a remainder carry register, as output signals which may be combined to generate a final quotient signal.

Abstract: A buried heterostructure tunable diode laser (100) or laser array and a method for making the same are disclosed. The active region layer (108) is buried between two lead salt semiconductor layers (106,110) containing europium and selenium that are of mutually opposite conductivity type and have substantially the same lattice constant as the active region layer. In addition, the europium and selenium containing lead chalcogenide layers have an energy band gap greater than that of the active buried layer and an index of refraction less than the active layer. The buried structure enhances electrical and optical confinement, reduces threshold currents, and provides a stable single mode laser. Strontium, calcium or tin may be used in place of the europium. The buried laser and array may be produced using a two-step molecular beam epitaxy method.

Abstract: There is disclosed a process for extracting diamondoid compounds from a fluid which comprises separating diamondoid compounds for a diamondoid containing fluid. The fluid typically is natural gas containing diamondoid compounds or a hydrocarbon liquid containing diamondoid compounds in solution. 
     One separation process involves: mixing the gas stream with an aromatics distillate oil; controlling temperature and pressure to maintain part of the mixture in the liquid phase; separating the mixture into a vapour stream and a diamondoid enriched aromatics stream; contacting the vapor stream with silica gel in a first sorption zone to sorb at least partially a portion of the diamondoid compounds from the vapor stream; and recovering diamondoid compounds from the silica gel in a second sorption zone by contacting silica gel with a regeneration fluid in which diamondoid compounds are at least partially soluble. 
     Three methods are disclosed in recovering diamondoid compounds from the diamondoid-enriched aromatics stream. One involves absorption in the pores of a zeolite porous solid. Another involves extraction of the aromatics component. The third involves separation by a thermal gradient diffusion process.

Abstract: An elevator information display system including an electroluminescent (EL) screen displaying elevator and building related information ( Figs. 1-5 ), one in each car and one in the lobby for each car ( Fig. 7 ). An additional remote screen, which displays the same information as the primary screen, can be mounted some distance away from the primary screen. The ELD is controlled from two sources. The elevator management/monitoring system (EMS), if it exists in the elevator system, communicates commands and data to the ELD via an appropriate communications link, and for the most part these commands cause the ELD to store and display the building related information. The ELD also receives serial display information (discrete and data) from the remote station link (RSL). This path provides the information required for the ELD to display the elevator related information. The basic display elements or components of the ELD system include - an ELD glass (screen), an ELD interface printed circuit board (PCB) mounted behind the glass, an ELD remote station interface PCB (directly connected to the ELD interface PCB), all mounted together in a common package frame ( Fig. 15 ); and an associated ELD power supply assembly. The ELD receives commands and data from the EMS, which cause it to display specific information or to receive downloaded data required for later display commands. The EL display screen displays elevator related information in the upper portion of the screen and separate, business related information in the lower portion, divided by a horizontal line displayed on the EL display screen.

Abstract: In conventional spraying methods the problem in the preparation of small carrier particles aimed for the polymerization is that the drops constituting the prestages of the particles agglomerate or form otherwise in different sizes, whereby the size distribution of the carrier particles becomes too broad. This leads due to the so-called replica phenomenon to a polymer product having also a too broad particle size distribution. In the present invention the carrier is prepared by spraying a liquid containing a carrier through a nozzle into inert gas so that its first forms small droplets, which then solidify to small carrier particles. The desired narrow particle size distribution is provided by feeding a liquid containing a carrier through a nozzle, in which or in connection with which the liquid drops by means of the standing sonic waves in the ultrasonic range into small droplets of uniform size. The droplets of uniform size solidify then into small carrier particles of equally uniform size.

Abstract: Novel acellular anti-pertussis vaccines are described, which comprises a non-toxic double mutant of pertussis toxin (PT), filamentous haemagglutinin (FHA) and the 69 kilodaltons protein (69Kd) taken alone or in combination with the diphtheria and tetanus anatoxin. The completely non-toxic double mutant of the PT is characterized by the fact that is comprises in the amino acid sequence of the S1 subunit the substitution of Glu 129 and of one of any other amino acid of the subunit, whose substitution brings about a decrease in toxicity, by natural amino acids. Moreover there are described purification methods for, and the characterisation of the FHA and the 69 Kd protein expressed by transformed  B. pertussis  W28-9K/129G strains, which produce the PT double mutant and by transformed  B. pertussis  W28-ΔTox which do not produce the PT. These proteins are particularly suitable for preparing safer and more immunogenic acellular anti-pertussis vaccine.
