IPC: B21D22/20
Filed: 1990-03-01
Abstract: ABSTRACT OF THE DISCLOSURE    A method of mechanically imparting a surface texture to a blank surface of sheet metal, especially soft aluminum, in which an adherent foil is applied at least to one surface of the sheet metal and is pressured into and against a surface by a roll so that the sheet metal is deformed and the pattern of the deformed foil is pressed into the sheet metal surface.

Title: A grid apparatus for a color cathode ray tube which eliminates vibration of the grids
Inventor: KUME HISAO
IPC: H01J31/20
Filed: 1990-04-12
Abstract: A grid apparatus which has a multiplicity of ribbon-shaped grid elements stretched in tension and attached to a frame which comprises a pair of support bars and a pair of resilient support members. Metallic members which have a larger thermal expansion coefficient than the resilient support members are connected to the reverse surfaces of the resilient support members opposite the side to which the grid-elements are attached. In the grid apparatus during heat treatment, thermal creep of the grid elements is prevented so that the tension of the grid elements will remain high when the normal temperature state is resumed.      A method of making such grid apparatus includes an additional heat treatment such as a blackening process after the reduction of the tension applied to the grid elements by the resilient support members and the support bars, hence preventing thermal creep of the grid elements to produce a high-reliability with high tension of the grid elements.

Title: Battery compartment
Inventor: DULANEY KENNETH L
IPC: H01M2/10
Filed: 1990-06-11
Abstract: BATTERY COMPARTMENT                   ABSTRACT OF THE DISCLOSURE A battery compartment for portable electrical equipment such as computers, tape recorders, VCR recorders, camera flash equipment and other such devices has an internal configuration and appropriate electrical connections to receive at least two different types of battery cells which may be of different dimensions.  These can include standard dry cell batteries and rechargeable NiCad batteries, for example.  The power pickup from the two types of cells is different, so that non-rechargeable dry cells can be isolated from charge when external power is attached to the portable device, while rechargeable cells are not isolated from the charge.  The different dimensions are accommodated by orientation of the one type of cell-receiving spaces at right angles to the other type of cell-receiving spaces so that incorrect placement of the cell types is prevented.

Filed: 1990-10-01
Abstract: Process for solubilising peptide in a water-immiscible organic solvent, consisting in bonding a lipophilic group to the terminal carboxylic group of the said peptide via an amide or ester bond; this lipophilic group is characterised in that when it is bonded to L-serine a molecule is obtained whose solubility in water at 25 DEG C is lower than 30 g/litre. This lipophilic group is chemically defined and nonpolymeric. The invention also relates to a process for the synthesis of optionally protected peptides, in liquid medium, characterised in that it starts with an amino acid or a peptide solubilised in organic medium by a lipophilic A-L group bonded to the carboxylic functional group of the starting amino acid or peptide and in that the amino acids or the peptides to be condensed, which are activated on their acidic functional group and protected on their amine functional group and optionally on their side chain, are added. The peptides originating from the synthesis are optionally employed for the synthesis of medications, vaccines and agri-foodstuffs or plant protection products.

Patent CA-2029317-A1 (CA)
Title: Flame detection
Inventor: BAKER PETER D
IPC: F23N5/08
Filed: 1990-11-05
Abstract: ABSTRACT OF THE INVENTION       The presence or absence of a flame in an engine combustion chamber is detected by monitoring the level of radiation at two different wavelengths.  One wavelength is between 470nm and 530nm whereas the other wavelength is about 670nm.  The ratio of the level of radiation at one wavelength to that at the longer wavelength is measured.          When the ratio is between about 0.1 and 1.0, this indicates the presence of a flame.  When the ratio is outside this range this indicates absence of a flame and causes a signal to be supplied to an igniter control unit.

IPC: D07B3/00
Filed: 1991-02-07
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus winds multiple strand ends on a bobbin, strands of the ends forming a band.  A pair of metering wheels accept said plurality of strand ends from tensioned supply spools and equalize their lengths.  The metering wheels are rotatable on angularly inclined axes such that the band proceeds on a helical path.  A rotation sensor on the metering wheels senses the speed of the band.  A threading assist clamp is mounted for helical displacement on a threaded crank arm for placing the strands on the metering wheels as a group, the clamp being removable from the crank arm to accomplish threading downstream of the metering wheels.  A traversing mechanism and bobbin drive wind the band on the bobbin, the traversing mechanism having a compensating pulley and a reciprocating pulley driven by distinct thread pitch areas along a common shaft.  A processor senses rotation of the metering wheels and controls both a bobbin drive motor and a reversing servo motor for rotating and reversing the common shaft.  The processor can be responsive to an operator interface for winding bobbins under direction from the operator interface, and can produce management reports.

Title: Opposed arm web accumulator
Inventor: MEYER THOMAS C
IPC: B65H20/34
Filed: 1991-09-24
Abstract: Abstract of the Disclosure In one embodiment of a web accumulator, at least one pneumatic cylinder actuator has a chain loop connected to opposite ends of its piston rod.  Trans-lation of the chain in response to pressurizing the cylinder causes the chain to drive two spaced apart axle shafts in the same rotational direction.  An arm is fastened to each axle shaft and there is a row of rollers on each arm and a roller on each axle shaft. Web is threaded in loops back and forth between roll-ers on the respective arms.  When the web infeed rate to the accumulator and the outfeed or rate at which the web is drawn out by a web consuming device are equal,  the regulated air pressure to the actuator drives the arms apart to thereby accumulate a long length of web.  When web infeed is interrupted while outfeed or draw persists, the arms are pulled toward each other and they pay out the stored length of web. In one embodiment, web tension may vary with the an-gles of the arms on each side of an imaginary center line to which the axes of the axle shafts are perpen-dicular.  Compensation for such variance may be made by varying the air pressure in accordance with such angle.  In the other embodiment, the chain drives the axle shafts through a lever whose radius varies along its profile, providing constant tension throughout the range of angular motion.
