Abstract: The present invention relates to biotechnology and genetic engineering, particularly the expression of proteins of viral origin in microorganisms through their fusion, by applying the recombinant DNA technology, to bacterial peptides. The present invention provides an efficient process for the expression in Escherichia coli of heterologous proteins as fusion polypeptides with a view to obtaining them with a high degree of purity, in commercially useful amounts, and in an appropriate form for their inclusion in vaccine preparations intended to human use. To this effect, what is essentially used is a stabilizing sequence derived from the first 47 amino acids of the antigen P64k of Neisseria meningitidis B:4:P1.15. In particular, use is made of a recombinant plasmid containing said sequence, under the control of the tryptophane promotor of E.

Abstract: A combination trowel and screwdriver is provided wherein the trowel handle houses and removably retains a tool bit drive assembly which houses a plurality of tool bit or screw drives. The user pivots the tool bit drive assembly housing away from the handle to a position extending in the proximate direction from the handle. The user then selects the desired tool bit drive for insertion at the proximate end of the assembly and with the proximate end of the handle screws the screw into a recessed position in a wallboard construction. The user then retracts or repivots the tool bit drive assembly into the handle, and then with the trowel end putties or spreads a wallboard plastic or finishing material over the recessed screw head to finish the wall.

Abstract: A DC power source device in which the voltage dividing ratio of a voltage dividing circuit of an error detecting circuit is changed from a reference value to a value smaller than the reference value thereby to decrease the voltages of DC outputs. In the device, a bleeder circuit in which the connection and disconnection of a bleeder resistor are switchable, is connected to a reference DC output among the above DC outputs which is to be subjected to error detecting. After the voltage dividing ratio is changed to the smaller value, the bleeder resistor is connected to the reference DC output for a predetermined period of time.

Abstract: This invention was devised in order to create a favorable playing environment in a video game by automatically providing an optimum viewpoint without placing a burden on the player.

Abstract: A plurality of sensing units are buried at suitable intervals in an area of ground or a snow accumulation section to be observed. Each of the sensing units includes a gyro-sensor for, when external force acts on it as a result of the displacement of the ground or the snow accumulation section, sensing impulsive acceleration from the magnitude and direction of the displacement and the inclination of the sensing unit itself, and a transmission section for transmitting the sense data by radio. A base station acquires the sense data transferred from the sensing units, processes the sense data for each measuring point in real time, determines the movement of the ground and/or the snow accumulation section, and judges a state of the ground and/or the snow accumulation section on the basis of the movement.

Abstract: A spacesaver product display hanger system includes long and short elongated members having different horizontally spaced information displays, and each product display has a hook for displaying and hanging product packages in a space saving manner while permitting conventionally sized and readable bar code product information on the product information displays. The display members or hangers are mounted with two long information display members immediately juxtaposed to each other with a short information display member disposed between and behind the two long information display members, so that the three hookloads of such product packages are disposed within the transverse horizontal space occupied by the two long information display members. The present system provides conventionally sized bar codes and other product description and pricing information, while providing three product displays in the space normally needed for at most two product package displays.

Abstract: A drive tool has a handle with a hexagonal sleeve for holding a plurality of tool bits. The sleeve is pivotally connected to the handle from an extended operable position to a stored inoperable position within the handle. The drive tool is provided with cross-holes for providing torque to the hexagonal sleeve or the drive bits using the handle as a lever.

Abstract: The invention relates to an extruder apparatus for the extrusion of caoutchouc mixtures and plastics, having a gear extruder consisting of a housing in which a pair of gears that mesh with one another, and two intake rollers, are housed, and there is also provided in the apparatus two intake channels and one extrusion channel. It is the task of the invention, by simple means, and in a simple manner, to improve material intake and to better fill the tooth spaces with the material to be extruded, and by doing so, to reduce inclusions of air that are brought along as well. The invention resides in the fact that one pushes in the material to be processed, as far as possible into the tooth spaces of the gears by means of the intake rollers, which are arranged at a point at which the teeth of the gears constitute, together with the inner wall of the housing, an intake slot, and in so doing, one expels, at least in part, the air that is situated in the tooth spaces.

Abstract: A driver bit tool having an elongate handle that has a central channel through which a predetermined length portion of the bit driver can be inserted. The driver bit is retained within the handle by any suitable means and one or more relatively thin magnets having high energy products are arranged on the side of the handle in close proximity to the driver bit receiving channel for generating a magnetic field which is substantially normal to the handle axis, the field created by the magnet being coupled to the driver bit. The position of the magnets and annular sleeves of magnetizable material are preferably used to optimize coupling of the field to the driver bit to optimize the amount of magnetic field that passes through the accessible operative tip of the driver bit so as to effectively magnetize the exposed driver tip of the bit driver.

Abstract: A master control system for conserving water used by sprinkler systems within a predetermined geographical region includes a plurality of sprinkler systems each of which is assigned an identifying indicia. A transmitting station is arranged for transmitting control signals receivable at any location within the geographical region. A valve connects each sprinkler system to a water source for selectively feeding water to an associated sprinkler system when the valve is open and for precluding water from being fed to the associated sprinkler system when the valve is closed. A receiver is provided for each sprinkler system within the region connected to an associated valve for receiving the control signals and generating a disabling signal for causing only said valves for the sprinkler systems assigned said identifying indicia to open independently of their status.

Abstract: A printer system includes a printer on which color and monochromatic print cartridges are mounted, and a personal computer to output bit map data to the printer. The kinds of these ink cartridges are memorized as status information within a RAM so that the personal computer can detect a cartridge mounted position based on the status information. In the case that the color and/or monochromatic print cartridge is mounted incorrect, the personal computer detects an amount of a difference from a normal mount position to cause print data to shift depending upon the difference, thus creating bit map data.

Abstract: An automatically braking mechanism for a rolling door system is used in connection with en elongate support shaft for selectively rolling up or lowering the rolling door formed of a series of connected slats. A driven wheel is fixed on the support shaft and a motor drive is provided for driving a chain drive sprocket wheel and a continuous roller chain couples the drive and driven sprocket wheels. The roller chain normally moves along a predetermined path prior to failure of the roller chain when the roller chain is under tension. A braking mechanism includes a first elongate sensing arm pivotally mounted at one end and carries a follower roller at the other end which is normally in direct contact wit the roller chain. A second elongate actuator arm is integrally formed with the sensing arm so as to be pivotally mounted for sharing common angular movements with the sensing arm.
