Title: Printer having ribbon wear indicator
Inventor: SILVERMAN STANLEY
IPC: B41J29/20
Filed: 1989-05-18
Granted: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE         A dot matrix line printer is disclosed in which the amount of wear of an ink ribbon is measured by continuously compiling data representing impacting action of the printer as the printer prints.          In a first embodiment, this is accomplished by initially determining a dot count based on the length of the ribbon and representing the maximum theoretical useful life of the ink ribbon and then decreasing the initial dot count as printing thereafter commences.  The dot count remaining is continuously divided by the initial dot count to determine the percentage of ribbon life remaining. When the dot count has been decreased substantially to zero, a worn ribbon indication is provided to initiate an audible or visible alarm and to prevent further printing until the worn ribbon is replaced.  As printing occurs the dots actually printed are counted, and this count is applied to reduce the initial dot count at a rate determined by the type of printing being undertaken.  This job rate can be changed as often as desired during use of a ribbon. In an alternative embodiment the expected ribbon life is translated into a number of dot rows to be printed, and the number is reduced in accordance with the number of dot rows printed as printing thereafter commences.  When the dot row number has been reduced substantially to zero, the worn ribbon indication is provided.

Abstract: ABSTRACT OF THE DISCLOSURE         A support arrangement which allows pivoting of a non-rotatable shaft has a flexure structure and a pair of axially-displaced inner and outer hubs respectively connected to, and disposed inwardly and outwardly of, the flexure structure.  The flexure structure is composed of disk-shaped flexural elements disposed in stacked, axially spaced relation to one another and connected peripherally one to the next.          The flexural elements together define a frictionless, laterally stiff, fulcrum or pivot point about which the shaft can pivot through a predefined range of angular motion.  The inner hub is attached to an inner end one of the flexural elements at an interior peripheral edge thereof, whereas the outer hub is attached to an outer end one of the flexural elements at an exterior peripheral edge thereof.  The shaft extends axially through the bores in the hubs and an opening in the flexure structure along a common axis, and is rigidly attached to the inner hub.  The outer hub which supports the inner hub and thus the shaft, via the flexure structure, is attached to an external support structure.

Abstract: Abstract of the Disclosure The invention is a method and apparatus that comprises supplying a mixture of gases to a constricted plasma arc.  The mixture comprises a gas that will sustain the plasma arc at the lower voltages typical of electric-arc welding and in the absence of a plasma and a gas which provides good heat transfer characteristics.  The relative proportion of the gas that will sustain the plasma arc at the lower voltages present in the mixture is large enough to support the plasma arc, and the relative proportion of gas having good heat transfer characteristics present in the mixture is small enough to prevent failure of the arc at the lower voltage.  A voltage drop is maintained which is high enough to maintain the plasma arc using the gas mixture while low enough to operate at a substantially constant current using a low voltage constant current power supply.

Abstract: Process and circuit for carrying out said process for control of the transmission of PCM signals between subscriber stations of a PCM time-division multiplex communication network in a conference service by means of a central conference control circuit in which a central processing unit allots to each station involved in a connection a transmitting pulse with cyclically repeated transmission time slots occurring in sequential pulse brackets of time frames and a receiving pulse with cyclically repeated receiving time slots occurring in sequential pulse brackets. The PCM signals are algebraically summed immediately upon their receipt and temporarily stored in a manner specific to the receiving station only until the expiration of the next succeeding period of signals not relevant to the conference, at such time when they will be transmitted to their respective conference related stations and subjected to a partial summation. The invention avoids a long delay between the respective receiving and transmitting processes and further simplifies the control of the signal processing and the central conference control circuit.

Abstract: A container closure (122) comprises a cylindrical molded unitary member defining a top panel (122h) and a skirt depending from the top panel to an open end for securement to the container, the skirt being interiorly tapered (122f) at the open end. The taper begins flush with the outer surface of the skirt (122g) and ends in a first circumference extending radially of the central axis of such cylinder. The skirt further defines a bead (122d) extending radially interiorly of the skirt to a second circumference radially closer to the cylinder central axis than the first circumference. The closure provides sealing retention pressure in accordance with the radially interior extent of the bead and exhibits evidence of an initial removal from the container. In one embodiment, the bead is generally of semispherical configuration and flow passages (122d-1) may exist in the bead, preferably over less than the hemispherical extent thereof. In another embodiment; said skirt further defines front and rear locking tabs (220, 220A, 226) respectively mutually spaced perimetrically at a location above said tapered surface and a bead at a location below said top panel and said locking tabs. The method for making the closures involves the use of a stripper plate (118) to participate in part in defining a mold cavity.
