Abstract: BINARY TRANSVERSAL FILTER ABSTRACT OF THE DISCLOSURE The present invention deals with a binary transversal filter which has a plurality of stages of shift registers that are driven by timing signals of a frequency which is greater by a number of times that of clock pulses being introduced, and a weighting circuit which weights outputs of shift registers of each of the stages, so that outputs of the weighting circuit can be synthesized. The charac-teristic feature of the present invention resides in the facts that NRZ signals are introduced into the shift registers, and the shift registers are driven by timing signals of a frequency which is greater by M times that of clock pulses of the NRZ signals.

Abstract: Abstract of the Disclosure A fiber glass mat making process is described which utilizes An improved method of transferring unbonded mat from a mat forming chain to a bonding station on a continuous basis.         The system involves passing the unbonded mat from a continuous conveyor surface to a roll which has on its surface a draped conveyor chain rotating around the roll but driven by the roll on which it is draped.  By permitting the draped chain to hang freely below the roll and to rotate with the roll stray strands falling between the conveyor surface and the roll are returned on the draped chain to the feed end of the bonding station.  Means are also provided to maintain the draped chain centered to insure that mat is delivered to the bonding station in a straight line from the conveyor surface.

Abstract: ERROR PERFORMANCE MONITORING FOR DIGITAL TRANSMISSION         SYSTEMS     Abstract of the Disclosure A periodically reset flip-flop is set when an error is detected in the bit stream of a digital transmission link being monitored. A counter is incremented in response to each period during which the flip-flop is set and is decremented in response to a plurality of periods during each of which the flip-flop is not set.  An alarm signal is produced if the count reaches a certain value.  In the presence of the alarm signal, the number of error-free periods which must occur to decrement the counter is increased.  The arrangement is less sensitive to error bursts causing false alarms than bit-error-rate monitoring arrangements.    - i -

Abstract: INTRALUMENAL ANASTOMOSIS SURGICAL        STAPLING INSTRUMENT ABSTRACT OF THE DISCLOSURE A disposable surgical stapling instrument for the joining together of tubular body organs such as the organs of the alimentary canal.  The instrument comprises an elongated body having a tubular housing portion and a coaxial cylindrical handle portion. The tubular housing portion supports at its free end a coaxial cylindrical casing containing at least one annular array of surgical staples.  An adjusting rod is coaxially and non-rotatively mounted within the instrument body and has a first end extending beyond the staple-containing casing.  An anvil, of improved configuration for easier removal from the anastomotic site, is removably mounted by means of an anvil nut on the first end of the adjusting rod facing the staple-containing casing.  By means of an adjustment knob at the free end of the instrument body handle portion, the anvil and the adjusting rod are shiftable axially of the instrument body between a position wherein the anvil is adjacent the staple-containing casing and a position wherein the anvil is spaced from the staple-containing casing.  The anvil has a plurality of anvil pockets formed therein to clinch the staples over a range of distances between the anvil and the staple casing constituting a working gap. The adjustment rod has a second end mounting an indicator cooperating with the adjustment knob to give both visual and tactile indications that the anvil is spaced from the staple casing within the operating gap.  A ring scale is mounted on the adjusting knob enabling accurate setting of the distance between the anvil and the staple casing, within the working gap, according to the thickness of the tissue of the tubular body organs being joined.  The instrument is also provided with a lever actuated staple driver and scalpel assembly and a slide safety lockout to prevent undesired actuation of the lever.

Abstract: Abstract of the Disclosure The invention concerns a photopolymerizable mixture of (a) acrylic monomer such as 95 parts of an alkyl acrylate and 5 parts of acrylic acid and (b) 0.01 to 2 parts by weight of a chromophore-substituted-halomethyl-s-triazine.  The invention differs from the prior art in that the s-triazine has the formula   wherein R1, R2, R3 and R4 ar independently hydrogen, alkyl or alkoxy groups, and 1 to 3 of R1, R2, R3 and R4 are hydrogen.  This s-triazine can be made by a more simple and hence more economical process than can the s-triazine of the prior art, tends to provide desirably shortened reaction times and somewhat greater tolerance to oxygen, and avoids the yellowish color encountered in the prior art.  The novel photopolymerizable mixture is primarily useful for making pressure-sensitive adhesive tapes.
