Title: Multivalent hepatitis b virus vaccine
Inventor: KNISKERN PETER J
IPC: C12P21/02
Filed: 1992-09-16
Abstract: TITLE OF THE INVENTION A MULTIVALENT HEPATITIS B VIRUS VACCINE          ABSTRACT OF THE INVENTION     In order to produce a mixture of different serotypes of hepatitis B virus (HBV) surface proteins in the form of particles, DNA encoding two or more HBV proteins were expressed by a single recombinant yea8t host.  These HBV proteins display the antigenic sites genetically encoded by the S domain (including the preS domain) of the HBV virion envelope open reading frame and when expressed in a yeast host deficient in its ability to glycosylate, contain substantially reduced levels of entrapped carbohydrate when compared with HBsAg particles produced in yeast cells which are "wild-type" for glycosylation.  These particles are useful as a vaccine for both the active and passive treatment or prevention of disease and/or infection caused by HBV or other agents serologically related to HBV including antigenic variants in the immunodominant epitopes of the surface protein, and are also uæeful as antigens and immunogens for development of diagnostic tests for such diseases or infections.

Abstract: METHOD FOR MANUFACTURING A SACK OR BAG WITH AN END BEING RECTANGULAR IN THE FILLED STATE AND WITH A HANDLE, AND A SACK OR BAG MANUFACTURED IN ACCORDANCE               WITH SAID METHOD                       Abstract The present invention refers to a method for manufacturing a sack or bag with an end being rectangular in the filled state and with a handle piece, and sacks or bags manufactured according to said method.  For the solution of the object to simplify already known methods, at the end of a tube section with side folds, three parallel, pregrooved fold lines extending transversely to the side edges are formed.   Then the end is pulled open and a rectangular cover sheet provided with glue at its circumference is pasted thereinto,  at which a flap is formed by folding, wherein the fold edge of the flap lies approximately on one of the two fold lines.  After the application of a glued area, the section of the end above one of the two upper fold edges and the flap, the glued surface is glued to the opposite part of the end. Then the grip hole is cut by punching in the glued section between the fold edge and the outer end.  After the filling of the sack or bag the open end is sealed in a conventional manner.

Filed: 1992-11-30
Abstract: In this command and signal apparatus a cap (2) which comprises a shoulder carrying an annular diaphragm (3) at the side of the user appears through an opening of a cover plate (1). Displaceable arranged in the cap (2) is an acknowledgement element (4) with a hollow-cylindrical head part, a first guide, a second guide and a push rod. A sleeve (13) can be advanced, by way of a thread (12) extending at the circumference of a switch carrier (11), so far until this, together with the shoulder of the cap (2), forms a firm seat with the cover plate (1). Provided at the rearward end of the switch carrier (11) are board holders (14), which carry a second circuitboard (15) on which is arranged a microswitch (16) actuated by the pushrod. Arranged in the head part of the acknowledgement element (4) is an annular light conductor (18), which stands in connection with a first circuitboard (17) and which conducts the light from light-emitting semi-conductors integrated on the first circuitboard (17) to the underside of a glass pane closing off the command and signal apparatus at the front side. The light-emitting semiconductors are regulated by means of photo semiconductors in dependence on the ambient light, so that the light ring visible on the glass pane (19) lights up brighter the brighter the ambient light is. A flexible mufti-wire line (21) connects the first circuitboard (17) with the second circuitboard (15) by way of solder points (22) and plug contacts (23).

Abstract: An automatic frequency control circuit mounted on a mobile station in mobile communication.  The automatic frequency control circuit performs feedback control of an oscillation frequency of a local oscillator used in conversion of a reception frequency to an intermediate frequency signal in response to the count result of the frequency of the intermediate frequency signal.  If a receiver is not in the hand-off state, counting is performed for comparatively long time, if in the hand-off state, counting is performed for comparatively short time conforming to required stabilization performance at hand off.  Occurrence of variations in count values caused by fading is detected, and only the count values worthy of trust are used as a base of control.  A level drop caused by fading is compensated by self-oscillation.

Title: Support base for maintaining elongate posts in a substantially vertical position
Inventor: KRICKHAHN UWE
IPC: E01F9/60
Filed: 1994-02-08
Abstract: It is common during the installation of upright posts such as are typically used with traffic signs and the like to construct forms within the excavation to facilitate the pouring of concrete around the post, thus setting the post permanently in the ground. In the event a post becomes damaged it is thus necessary to re-excavate the site and set a new post. An alternate method utilizes a pre-formed base of rigid material with upward and inwardly tapering walls contained within which base is a vertically disposed hollow cylinder with a support and drainage means attached. An open end of the hollow cylinder protrudes above the upper surface of the base and is accessible for the insertion of one end of an upright post. Once inserted into the cylinder, the post is held in place by means of through bolts. Excavation of the site is thus required only once and the necessity for on-site concrete pouring eliminated. In addition replacement of damaged posts requires no re-excavation but rather the simple process of removing the damaged post from the cylinder housing and installation of a new post
