A data communication apparatus applicable to an automotive vehicle is disclosed in which a transmission data having a combination of bit data of "1" and/or "0" is coded into a communication signal based on an interval of time on a rising edge and/or a falling edge and the communication signal is transmitted via at least one signal transmission line. At least one of the intervals of times at a beginning of which a predetermined rising or falling edge occurs and at an end of which the subsequent r...

In an apparatus for reducing noises in a space, signals related to noise generating conditions of a plurality of noise sources are detected, a signal component of the detected signals is selected on the basis of determination of which signal component is predominant over the other signal component in the noises in the space, and the selected signal component is filtered through adaptively determined filter coefficients to output drive signals to control sound source, the filter coefficients bein...

The invention relates to a product to permit separation of cells in the domain of immunopurification and consisting of a finely divided carrier of a density lower than that of the medium from which such cells must be extracted, such carrier being covered with macromolecules capable of being specifically fixed to the cells to be extracted to which a priviliged orientation was given to enable fixation of such macromolecules.

New medical self-polymerizable sealing cement with an acrylic polymer and/or copolymer base, applicable for prosthetic implants, which is obtained by mixing a liquid phase and a solid phase. The liquid phase, being viscous, forms a collodion of an acrylic polymer and/or copolymer in at least one monomer, while the solid phase is composed of an acrylic polymer and/or copolymer possibly containing a mineral load. The new cement is not dangerous for the patient, due to an absence of monomer exudati...

A reusable plastic rearing panel applicable to aquaculture comprises a molded plastic panel having a plurality of recesses therein for nurturing and rearing rock scallops and other filter feeding bivalve mollusks with similar habits from juvenile stages to marketable adult size. At the bottom and sides of the recesses are defined perforations for relief permitting attachment of the contained bivalve by the bivalve's cementation. The recesses in the panels are covered by mesh to contain and prote...

A machine for inserting terminal pins into a printed-circuit board under programmed control has a pin-insertion head which is charged with pins from a reciprocating shuttle that executes only one stroke in response to each pin-insertion operation. The head is charged with a pin from one of two passages in the shuttle at the end of each stroke while the other passage is being loaded with a pin ready for translation to the head to recharge it, during the next stroke. The machine further includes a...

An instantly applicable correction fluid container structure is provided with a threaded cap which can semi-automatically dispense the contents via a port on the top of the cap by pressing down the upper conical portion of a spring-biased mounted control portions therein. The structure may provide the benefits in practice of convenience and prevents the drying of the contents of the container.

A crooked cut detecting system consisting fundamentally of a sensor for sensing irregularities developed on a cut end of a material from which a section was cut away by a sawing machine, an arithmetic means for deriving as a developed crookedness the difference between the maximum and minimum values of the above irregularities, and a comparator to compare the developed crookedness with a standard value defining a maximum allowable crookedness. The operations of the above fundamental constituents...

A container of the kind (1) having an area (4) on one of its faces (5) including an articulation line (6) about which it tends to flex in order to provide an opening (3) on an adjacent face to release the contents. Locking device, consisting of a bolt (8), hold the area (4) coplanarly with the face (5) including the same in order to provide a safety closure.

Actuating piston of disk brake is provided with self-retracting 3-element control unit carried, typically, in surrounding annular piston recess with one element in frictional or tensioned registration with wall of piston chamber. Elements are (a) radially tensioned anchorage ring which frictionally abuts chamber wall at piston-extension position, (b) axially compressible/resilient co-axial ring such as elastomeric O-ring, compression spring, or corrugated metallic washer which is compressed by p...
