IPC: C07K16/08
Filed: 1986-10-02
Abstract: This invention relates to a polypeptide exhibiting 
hepatitis B virus e antigenicity produced by a 
microorganism; a recombinant DNA comprising a DNA fragment 
coding for a polypeptide exhibiting hepatitis B virus e 
antigenicity; a recombinant DNA comprising a DNA fragment 
coding for a polypeptide exhibiting hepatitis B virus c 
antigenicity, wherein the nucleotide sequence between the 
SD sequence of the promoter and the translational 
initiation codon is ATCGGGC; and a method of preparing 
polypeptides exhibiting hepatitis B virus e and c 
antigenicity respectively, which comprises cultivating 
transformants containing above-described recombinant DNAs 
respectively.  
     The thus obtained polypeptide exhibiting HBc or 
HBe antigenicity may be used as a diagnostic reagent for 
HBV infection and a defensive (preventing) agent against HBV 
infection.  
     A recombinant DNA having a base sequence of ATCGGGC 
between the SD sequence of its promoter region and the 
translational initiation codon affords a gene product 
having HBc or HBe antigenicity with a high yield and is 
advantageously used for the production of HBc or HBe 
antigen.

Title: Apparatus and process for the biological purification of exhaust air and waste water
IPC: B08B9/00
Filed: 1987-06-10
Abstract: The outgoing gas or waste water is conveyed through a gas-liquid contact apparatus in which biological purification takes place. A bubble plate-type column (2) is used as gas-liquid contact apparatus. The biomass is distributed over the plates (3) in the form of an aqueous suspension with a layer height corresponding to a liquid content per plate greater than 0.07 m3/m2, preferably greater than 0.15 m3/m2 of column cross-section. During the biological purification of gas, the gas to be purified is supplied at the lower end of the bubble plate-type column (2). It then flows through the plates (3) and issues again as purified gas at the top of the plate column (2). When the plate column is used for purifying waste water, the waste water to be purified is conveyed from top to bottom through the plate column (2) and is traversed by air, oxygen or oxygen-containing gas. At the same time, a proportion of the biomass is separated from the purified waste water and re-circulated into the entering waste water or into the column. The waste water to be purified flows successively over the plates (3) to the liquid outlet (11). From here, the clarified waste water flows out through the overflow (13). This process is suitable, in particular, for highly charged waste water, particularly if a compact structure is required during construction of the apparatus.

Abstract: A wedge connector for securing the horizontal 
cross beams of a storage rack to the hollow upright 
posts of the system. Two ear-supporting members extend 
laterally from an elongated shank, each of which 
members carried an upwardly extending wedging ear. 
The wedge connector has a shape and carefully 
controlled dimensions that make it possible to insert 
the elongated shank and upper wedging ear into the 
lower slot of a pair of elongated slots in the upright 
post of the storage rack. The elongated shank is 
then pivoted up within the interior of the hollow post 
into a position where the upper wedging ear can be 
moved back out of the upper elongated slot of the 
pair of slots, to place the wedge connector in its 
operative position. The dimensions of the lower wedging 
ear of the wedge connector are controlled so that the 
lower ear can not be inserted in the lower elongated 
slot in the upright post.

Abstract: Microwave thermography apparatus comprises a signalreceiving aerial (2) which is sensitive to microwave radiation emanating from a body having a mean body temperature. A reference load (1) capable of being maintained at a chosen temperature (TO) and of emitting a thermal noise signal at microwave frequency corresponding to temperature TO, is connected to a receiver (3) the input impedance of which is matched to the impedance of reference load (1) by way of a 3-port non-reciprocal circulator (5). Aerial (2) is connected via a single-throw on/off microwave switch (6) to the input of receiver (3) through the other port of circulator (5). The connections to circulator (5), taken in circulation order, are reference load (1), aerial (2), receiver (3). Aerial (2) is preferentially designed to incorporate a tubular metallic waveguide (10) of circular cross-section dimensioned to support TE11 wave mode and the lower order mode, the signal output from the aerial (2) being taken by a coaxial line and the aerial (2) incorporating a broad band waveguide coaxial line mode transformer (11,12) which is arranged to select only the TE11 mode for delivery to the coaxial line. The waveguide (10) is filled with a low-loss dielectric material (13) in order to provide the aerial (2) with an impedance close to the mean body tissue impedance (about 80 ohms).

lenslets by exposing a photoresist material which has been 
formed over the array to ultraviolet light for a 
predetermined time sufficient to expose the photoresist 
material to sufficient radiation in the area between the 
lenslets, but not over the lenslets because the flux density 
there is less than between the lenslets and thereafter 
forming light blocking material between the lenslets.
