Patent CA-2006678-A1 (CA)
Inventor: KIMURA SADAO
IPC: B21D7/024
Filed: 1989-12-27
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention provides a device for bending thin metallic pipes suitably used as a fuel supply pipe, brake pipe and the like of an automobile, which are bent at a plurality of portions thereof not in the same direction but in three-dimensional directions.  The device according to the invention includes a station-ary mold form having a first and a second bending section to the shapes of which a metallic pipe is bent and a guide member erected upright on the mold form at the second bending section, a bending member arranged outside the mold form and movable toward the latter for bending the metallic pipe, a rotor for rotating the bending member and an actuator for operating the rotor through a wire.     The advantages of the invention are that unlike the con-ventional device, the bending member located outside the mold form is attached to the rotor which is rotated by the actu-ator through the wire, the interference of the actuator with the metallic pipe or other parts of the device or with another actuator is prevented and the structure of the device is sim-plified.

Title: Electrical cord transition assembly for the juncture of a work surface and an upright wall panel
Inventor: QUINN GAIL M
IPC: A47B21/00
Filed: 1990-02-12
Abstract: 55,011 ABSTRACT OF THE DISCLOSURE         A desk having a desk top defining a work surface, an adjoining upright wall panel along at least one edge of the desk top,  and an electrical cord transition assembly for a slot in the at least one edge of the desk top, at the juncture between the desk top and wall panel.  The transi-tion assembly includes a grommet which snugly lines the slot,  and a grommet cover which is pivotally attached to the  slot  via  a  substantially vertically oriented pivot axis.  The grommet cover may be easily assembled with the grommet,  even  when  the  grommet  is  individually  pre-assembled with the slot, but difficult to remove without removing the assembly from the slot.  Cooperative elements of the grommet and grommet cover form a tactile detent when the grommet cover is in a position which closes the grommet and associated slot.

Title: Method to improve directional survey accuracy
Inventor: COLES MARK
IPC: E21B47/022
Filed: 1990-02-20
Abstract: METHOD TO IMPROVE DIRECTIONAL SURVEY ACCURACY                     Abstract A method is proposed for better determining the azimuth and inclination of a borehole in which a priori information regarding the magnitude of the earth's gravitational field strength, it magnetic field strength and direction are utilized to constrain the measured components of the earth's gravitational and magnetic field vectors.  The constrained fit method adjusts the accelerometer and the magnetometer tri-axis measurement to optimize agreement between the measure data and the a priori magnetic and gravity field strengths and the magnetic dip angle.  The adjustment that is selected is that which produces the least increase in the statistical measure X2.

Abstract: ABSTRACT "Connection Device for Blasting Signal Transmission Tubing"     A connection device for blasting signal transmission tubing comprises a housing consisting of first and second hinged sections provided with cooperating arcuate raised portions and grooves which, when the housing is closed, define first and second arcuate, circular-section channels, interconnected by a further channel.  In use, first and second lengths of transmission tube are located in the arcuate channels and are partially cut by a blade mounted in the connecting channel to form apertures therein, whereby a portion of a blasting signal entering the connector via one of the tubes will spill out of that tube, traverse the connecting channel, and initiate a signal in each arm of the other tube.

IPC: H04B1/16
Filed: 1990-10-31
Abstract: In a communications system, a base station has a memory for storing interval control values representative of time-varying traffic pattern of the communications system. A time-keeping circuit recalls a stored interval control value from the memory according to different time of day and a battery-saving command signal is sent from the base station at variable intervals as a function of the value recalled from the memory. Power supplies of a remote station are interrupted for a constant brief interval in response to the battery-saving signal, so that the remote station is powered for a shorter interval during a light traffic period and for a longer interval during a heavy traffic period. In a preferred embodiment, traffic data is automatically collected from the communications system and the stored interval control values are updated according to the collected traffic data.

Abstract: An impression cylinder provided with a replaceable sleevelike impression cylinder shell is movably and releasably mounted in a printing press by means of a bearing in such a manner that the im-pression cylinder adjacent to its one stub shaft is adapted to protrude freely from the machine frame so as to permit a replacement of the impression cylinder shell. In order to permit a particularly simple re-placement of the impression cylinder shell, the bearings consist of hinged bearings having bearing shell sections which can be swung off to a position in which they permit the impression cylinder to be swung out in a horizontal plane. The impression cylinder is provided at one end with a stub shaft, which extends beyond the associated hinged bearing and which at the top of its end portion supports a supporting shell section, which is axially immovably mounted in the machine frame for rotation about a vertical axis. A movable horizontal supporting rail or slideway is provided, which is movable from below into engagement with the impression cylinder, or with a shaft portion connected to said cylinder, at a location between the bearings, and is adapted to be fixed in position, so that the impression cylinder which is held between the supporting shell section and the supporting rail can be pivotally moved out of the opened hinged bearings about the vertical pivot for the supporting shell section.

Title: Permeable, porous body for the treatment of gases and/or vapors and/or liquids and method of producing it
Inventor: ROEHLIG RAINER
IPC: F01N3/022
Filed: 1990-07-10
Abstract: Abstract 1.   Permeable, porous body for the treatment of gases and/or vapors and/or liquids and method of producing it.     2.1  For catalysts and filters for the treatment of gases, vapors of liquids, for example the exhaust gases of internal combustion engines, porous ceramic bodies have been used in the past.  These bodies are sensitive to shocks and, because of the poor thermal conductivity of the ceramic material, are in danger of overheating up to thermal destruc-tion when the soot deposits burn away.     2.2  By employing a body made of a permeable, porous sintered metal which may at least in part include the catalytically active components, there not only results increased strength which offers structural advantages but also improved operating characteristics.  If, for example, the bodies are employed as soot filters, the ignition process begins earlier due to their better thermal conductivity compared to the ceramic material. Thus the soot deposits burn off more uniformly.     3.   Figure 1

Title: Synthesis and elucidation of azamitosene and iminoazamitosene
Inventor: SKIBO EDWARD B
IPC: C07D487/04
Filed: 1991-02-27
Abstract: The synthesis of 2,3-dihydro-1H-pyrrolo[1,2-a] benzimidazole-5,8-diones (azamitosenes) (I) was carried out in conjunction with the design of potential DNA crosslinkers activated by reduction (reductive alkylation). These quinones resemble mitosene antitumor agents, but are based on the benzimidazole nucleus rather than the indole nucleus. Preliminary results indicate the azamitosenes are potent antitumor agents. Iminoquinone derivatives of azamitosenes (iminoazamitosenes) (II) were synthesized as reductive alkylating agents exhibiting low oxygen toxicity. The iminoazamitosenes are hydrolytically stable in neutral buffers and undergo buffer catalyzed syn/anti isomerization at the imino center. Electrochemical and oxygen reactivity studies in aqueous buffers indicate the change from quinone to iminoquinone is accompanied by an increase in reduction potential and a decrease in oxygen reactivity of the corresponding reduced species. <IMAGE>
