Granted: 1991-09-17
Abstract: SIGNAL REPEATER FOR MULTI SUBSCRIBER COMMUNICATION OVER SINGLE PAIR TELEPHONE LINE                 Abstract of the Disclosure A signal repeater for regenerating digitally encoded signals transmitted in bursts over a single pair telephone line to enable simultaneous communication be-tween a telephone central office and any one of up to four subscriber transmitter/receivers.  The repeater decouples signals from the line for regeneration thereof and recouples the regenerated signals onto the line. Clock frequency and phase information characteristic of the decoupled signals is derived in order to facilitate accurate regeneration of the signals.  The decoupled signals are decoded and then regenerated to replicate the signals originally produced by the telephone central office and subscriber transmitter/receivers respec-tively.  The regenerated signals are then re-encoded and recoupled onto the telephone line.

Title: Control for enabling flight timing of hammers during printing
Inventor: CARRINGTON JAMES E
IPC: B41J9/46
Filed: 1988-08-11
Granted: 1992-05-26
Abstract: ABSTRACT      A printer control apparatus provides a control circuit arrangement which enables flight timing to be performed during printing.  Basically, the invention achieves this by providing flight time control means activated by a print hammer operation signal. Preferably the control temporarily inhibits the continuation of print hammer operation.  Preferably the control inhibits print hammer operation subsequent to a selected print hammer by inhibiting the comparisons of print line and tape element data contained in storage devices of the print control.  Inhibiting may be for a fixed interval based on an average of the flight times of all the hammers.  Alternatively the inhibiting interval may be varied according to the individual flight times of the hammers.

Title: Epoxy resin, process for the preparation thereof and process for the production of epoxy foam
IPC: C08G59/24
Filed: 1988-10-12
Granted: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a process for the production of an epoxy resin foam, in which a polyepoxy compound having at least two epoxy groups is crosslinked and simultaneously foamed by the aid of a carbonate oligomer having terminal phenolic hydroxyl groups.          The product is highly flexible against compression, bending and warp.  The process proceeds without using a conventional foaming agent, since the carbonate oligomer releases carbon dioxide which acts as a foaming agent.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for producing the latch bearing in a latch needle for textile machines of the type in which a latch is pivotably mounted in a longitudinal slot between two cheeks of a needle shank by a hinge pin passing through mutually aligned transversely extending bores in at least one of the cheeks and a bearing portion of the latch between the cheeks.  In accordance with the method a cylindrical wire is provided with transversely extending notches at intervals corresponding to the length of a hinge pin.  The notched wire is converted by hot or cold treatment into a brittle, hard state.  Individual hinge pins are broken off from the wire at the notches, and are subsequently inserted into the bores in the cheeks and the bearing portion of the latch to be securely fixed there.  The apparatus includes a counter support and a clamping jaw respectively disposed on opposite sides of a space, for clamping a partially assembled latch needle in the space and a hole punch at the clamping jaw side of the space for passing in a hole punching direction through the cheeks and the transverse hole in the latch's bearing portion to form transverse bores therein which are axially aligned with the transverse bore in the bearing portion.  A slide bearing disposed at the counter support side of the space with the counter support being disposed between the slide bearing and the space, is provided with a counter punch to be slideably advanced toward the counter support.  A     transfer element between the slide bearing and the counter support is movable transversely to the hole punching direc-tion between a receiving position for receiving a hinge pin, and an insertion position where the hinge pin is axially aligned with the hole punch and the counter punch.  An insertion device is provided for inserting a hinge pin into the transfer element when said transfer element is in the receiving position.

Abstract: A central station (SC) is connected in series with the stations by a looped connection comprising a message loop (BM), a clock-signal loop (BH) and a state-control loop (BCE). Each station comprises an interface (I) connected to the various loops of the connection. The message loop routes messages transmitted by the central station destined for at least one interface, the responses from the interfaces, and messages transmitted by the interfaces destined for the central station. The clock-signal loop routes a clock signal transmitted by the central station and the state-control loop routes a state-control signal transmitted by the central station, this signal having a first value for a drive mode of operation and a second value for a reserve mode of operation of the interfaces; the passing from the first to the second value enables the control of a reset to zero of the interfaces. The clock and state-control signals have the same circulation sense, the messages having an inverse circulation sense.
