Abstract: ABSTRACT OF THE DISCLOSURE An automatic web splice control system determines when an expiring roll of web of indeterminate caliper reaches a preselected splice radius by sensing when the web roll has diminished to preset first and second radii and measuring the web length resulting from that diminishment to determine web caliper.  Then the system computes the roll cross-sectional area between the second radius and the preselected splice radius divided by that caliper to determine in advance the web length that will be drawn from a roll as the roll size diminishes from the second radius to the splice radius.  Commencing at the second radius, the system then measures the amount of web drawn from the roll and when that amount equals the precomputed web length, the system generates a splice signal indicating that the roll has diminished to the preselected splice radius.

Abstract: PUN,8248 18.11.76 ABSTRACT:                  Digital signal processing arrangement provided with a  wave digital filter which comprises quantizing means for limiting the signal waves present in this filter to a predetermined word length by means of "controlled rounding".  By controlled rounding a limit cycle free output signal is obtained when a constant input signal is present.  When the outgoing signal waves from the N-port adapter are equal to bo(j,k) and the signal waves applied to the adapter are equal to a(j,k), when b(j,k) is equal to the desired and quantized value of bo(j,k), wherein j represents the number of the port, then by means of controlled rounding bo(j,k) is now quantized in such a way that   Herein c(i,j) represent constants and r the plurality of independent information signal waves.

Abstract: VARIABLE RADIUS SPRINGBACK WAVY SEAL                     ABSTRACT OF THE DISCLOSURE         A variable radius labyrinth seal arrangement for use in a steam turbine apparatus is characterized by a flexible strip member having mounted substantially perpen-dicular thereto a series of corrugated uprights.  The strip is received within a circumferential groove provided in the turbine casing and is flexible to conform to the curvature of the groove, thus permitting seal use in a variety of turbine sizes.  The amplitude of the corrugations, or wavi-ness, of the uprights varies in acccrdance to the magnitude of the flexure of the strip necessary for the strip to conform to the groove curvature.  The strip is movably biased within the groove and responds to forces generated by contacts between the uprights and rotating turbine elements by displacing radially outward from that contact.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a process for humidifying an artificial sausage casing on a shirring machine wherein a moisture-providing fluid is contacted with the inside wall of the unshirred casing and the casing is subsequently shirred.          The moisture-providing fluid is a mixture of water and from about 0.5-5% of a surfactant having lubricating properties.          The fluid is applied to the casing in a proportion to provide from about 0.015 to 0.15 mg. surfactant per square inch of casing.  In this manner artificial sausage casings are produced with fewer defects in terms of damage on the shirring mandrel and fewer pinholes and greater elasticity to prevent breakage during stuffing.

Abstract: Abstract of the Disclosure A programmable control unit for use in small and medium size switching systems such as telephone exchanges is disclosed.  The unit makes use of a special register for generating the store addresses in the memory reference instructions by means of which more than half of the register loading instructions required for the setting of the full addresses can be eliminated.  The special register comprises two parts each separately addressable both for reading and writing operations so that during the per-formance of telephone-type functions, a significant spare in store capacity can be attained with respect to the required great number of transfer in-structions.  A microprogrammed control block uses only a part of the outputs of the special register which comprises only operational codes.  The volume of the microprogram store can be reduced significantly by suitable coding of the instructions.

Abstract: ABSTRACT OF THE DISCLOSURE      A power supply provides a low-level DC voltage to DC load circuits by first rectifying the standard AC voltage and thereafter reducing the rectified AC voltage to the low-level DC voltage.  The reduction of the rectified AC voltage to the low-level DC voltage is accomplished by a power transformer which is switched on or off by a pair of switching transistors.  The switching transistors are operated in a "push-pull" mode by a pair of control transformers operating in combination with a control circuit.  The control circuit produces various pulse conditions in the control transformers which turn their respective switching transistors on and off in a prescribed manner.  An overcurrent sensing and control device prevents damage to components.  The power on/fail circuit signals the load as to the status of the regulated load voltage and guarantees power for orderly shutdown after an input power outage.
