Patent NO-159863-C (NO)
Inventor: GRAHAM RICHARD S
IPC: C12N7/00
Filed: 1980-12-15
Abstract: A recombinant bacteriophage, a method for producing and selecting the recombinant bacteriophage and a method for heterologous cloning of DNA are disclosed. The recombinant bacteriophage is produced by ligating genetic fragments encoding a desired genetic trait with DNA from a bacteriophage, incubating with DNA from a second Bacillus microorganism prototrophic for a growth requirement, incubating with a host Bacillus auxotrophic for the growth requirement. Transformed host Bacillus are selected by growing the mixture on a growth medium which does not contain the growth requirement and determining the presence of the genetic trait. The recombinant bacteriophage containing the desired genetic trait is recovered from the host Bacillus by induction. Heterologous cloning can be accomplished by incubating a host Bacillus with the recombinant bacteriophage.

Abstract: Located below an aircraft is a support rod (1) provided with female engagement members (10). Standard missile launcher modules are provided on their flat upper wall with counterpart male engagement members (20). The engagement members (10 and 20) cooperate in the manner of dovetails and for each module location, they are separated from each other according to the same geometric progression along the support rod (1) and the upper wall of the module (2). A device comprising a cam (27) and lever (273) makes it possible to ensure at the same time the translation necessary for locking of the dovetail, as well as the making of contact between the electrical connector members.

Abstract: The invention relates to a method for producing reinforcement intended for concrete members, preferably concrete piles. Through internal means acting as strut members or compression members in the form of diagonally, or otherwise, acting struts, the longitudinally extending reinforcing bars 20 within an elongated coil are brought into place against the inside of the coil with a predetermined force, thereby stabilizing the coil. The struts can be arranged as diagonally acting elements in a reinforcement having four bars forming a square seen in cross-section or the struts can contact all or certain of the reinforcing bars, but preferably in such a way that the struts mutual orientation is changed as the supporting operation proceeds along the elongated coil. <IMAGE>

Title: Programming signal source and calibration data for a speedometer/tachometer with calibration switches
Inventor: DANNENBERG ROBERT D
IPC: G01P21/02
Filed: 1989-12-15
Granted: 1999-05-04
Abstract: A  speedometer/tachometer  assembly  for  an  automotive vehicle, such as a heavy truck, has a ten section DIP switch for  calibrating  the  speedometer  and  a  like  switch  for calibrating the tachometer.   When set to all  "0's",  each switch causes the corresponding meter  to be driven by a variable frequency signal from a corresponding sensor,  as calibrated by a corresponding calibration factor that has been   preloaded   in   the   non-volatile   memory   of   a microprocessor that operates the meters.   When set to all "l's",  each switch causes  the corresponding meter  to be operated from pre-calibrated data appearing on a data link. When set to any other setting, the setting determines the calibration  factor  that  is  applied  to  the  uncalibrated signal, and this is used to drive the corresponding meter.

Title: Three-way valve
Inventor: GATTOLLIAT ANDRE
IPC: F16K31/06
Filed: 1990-07-24
Granted: 2000-11-14
Abstract: The three-way valve has a chamber in the body which is adapted to provide a connection from an outlet passage to both inlet passages. One inlet passage is closed by a valve lid which bears on a valve seat and which functions as an automatic outlet valve when the armatures moves into a top position. The other valve lid moves independently in dependence on the inlet pressure of the second inlet passage and the pressure in the outlet passage. In the illustrated rest position, the armature acts by way of a convex closure member to press the lower valve lid onto a valve seat about the second inlet passage.

Granted: 1995-05-02
Abstract: A tubular arrangement the front end of which defines a fastener outlet is extendably and contractably mounted to a fastener driver body.  A drive bit is mounted within the tubular arrangement. A fastener feeder is mounted to the tubular arrangement and contains a pair of fastener guiding plates opposite each other with a predetermined distance sufficient to pass a strapped fastener assembly.

Title: Method for making image conversions with error diffusion
Inventor: ESCHBACH REINER
IPC: H04N1/387
Filed: 1991-08-16
Granted: 1999-03-16
Abstract: A method of image conversion takes an original print ready image at a first resolution scaling and orientation, and simulates printing that image by creating a representation of a page at the particular resolution, scaling and orientation. The image is then periodically sampled through the page with an aperture that corresponds to the desired output. Because the resolution, scaling and/or orientation of the "print" and "scan" are distinct, the aperture "sees" areas which may correspond to more than a single pixel on the original image, and thereby may derive a signal that is gray, i.e., the aperture may see an area that is neither completely black or white, and the image data derived will be considered gray. The gray image data, which may be definable at several bits per pixel, is then made print-ready by reducing the number of bits defining each pixel to a valid output state (0, 1 for a typical binary printer, 0, 1, 2, 3 for a quaternary printer, etc.). The reduction step is accomplished through error diffusion methods that maintain the local area gray density level. In color applications, each of the bitmaps representing a color separation, be it 2, 3, 4 or any other number, is treated independently with the same method.
