Abstract: ABSTRACT OF THE DISCLOSURE:         The sphygmomanometer comprises an arm band having an inflatable cuff and a microphone, and an instrument connected to the arm band, which contains the necessary pneumatic and electronics elements. By means of the micro-phone and an amplifier, electrical signals corresponding to the Korotkoff sounds are generated during the decompres-sion phase, and are applied to a discriminator. At the appearance of the first and the last signals, corresponding to the Korotkoff sounds, and each having an amplitude at least equal to a-threshold value, the pressure in the cuff is measured and stored in memory as the systolic pressure and diastolic pressure, respectively. During the decompres-sion phase, the threshold value is first decreasing like a value proportional to the pressure in the cuff; then it increases at appearance of each signal corresponding to a Korotkoff sound and exceeding the instananeous value of the threshold level, after which it decreases again. This varia-tion of the threshold value allows an exact determination of the blood pressure, eliminating in the optimum manner the parasite signals over a large range of pressures and in a large domain of Korotkoff sound intensities.

Abstract: ABSTRACT            A versatile filter structure adaptable for use in differently ported configurations includes accommodation for variations of bypass and shutoff valving and for filter element replace-ment from either end or centrally of the structure.  A head casting is secured to a tubular housing and either may be the mounting device for the filter.  A funnel shaped diverter having an oblique edge is removably mounted in the head casting and provides separation between inlet and outlet portions of the filter structure by means of an eliptical o-ring seal at the edge which engages the interior of the head casting.  The diverter provides a smooth transition for fluid flow to the interior of the filter, supports one end of the filter element in the tubular housing, optionally houses a shutoff valve operative automatically upon filter element removal, and further houses a bypass valve for safe-guarding against filter element blockage.  The remote end of the housing which also supports the filter element consists in the different configurations of a welded-closed or removable end assembly, with or without a port and shutoff valving.  An indicator mounted on the head casting is in fluid communication with opposite sides of the o-ring seal to monitor inlet and outlet pressure differentials.  Dual diaphragms actuate and isolate a sensing piston in the indicator and a dual spring arrangement biases the piston for normal operation and to provide an indication of lack of filter element in the housing.

Abstract: ABSTRACT     In an overhead conductor in which an optical fibre is loosely housed in the bore of a circumferentially rigid central metal core the optical fibre is secured to the central core at each of a plurality of longitudinally spaced positions along the length of the conductor by a local deposit of resin.  The part of the optical fibre extending between any two local deposits of resin is loosely housed in, and of a length substantially greater than that of, that part of the bore.  Risk that the excess length of the optical fibre will accumulate at the lowest point of the bore of a suspended conductor is thereby reduced.

Abstract: ABSTRACT OF THE DISCLOSURE        A  fibre web is supported by a fabric or between two fabrics and passes through a press nip formed by two press rollers to be de-watered by pressing.  An elastic compression mat or plurality of mats thicker than the fabrics also pass through the press nip.  The mater-ial and/or structure of the mat or mats is selected so that, based on the phenomenon of hysteresis, a retardation is obtained for the restor-ation of the thickness of the mat, occurring after the median line of the nip, such that the compression pressure in the nip is reduced rela-tively steeply, as compared with a symmetric distribution of the nip pressure, and due to the retardation the fabric or fabrics may be sep-arated very soon after the median line of the nip, so that rewetting of the web is reduced.

Abstract: ABSTRACT   A way of enhancing spectator enjoyment of football.  Each referee has a holder for the flag.  When an off-side, clipping, backfield in motion, etc., is observed, the referee drops the flag to signal a rules infraction.  The holder senses the removal of the flag. By means of a radio link, the sensing of the flag re-moval is relayed as to a receiving station.  In turn, a signal flashes on the stadium scoreboard and on the televised transmission as viewed on a television re-ceiver screen.  By virtue of this arrangement, the spectators know that the play may be called back, even though the players themselves may not be aware that a flag has been dropped to signal a rules infraction and will continue to play.

Abstract: OUTRIGGER ARM DISPLACEMENT CONTROL MECHANISM     Abstract of the Disclosure As the outrigger arms of a borehole logging tool are flexed inwardly and outwardly according to the diameter of the borehole opening through which they pass, the corresponding axial displacements of the ends of the arms are controlled to determine the axial positions of the arms relative to the tool.          Specifically, as the arm ends move, they are caused to rotate by a cam mechanism.  The stiffness of the arms causes the arm ends to rotate in unison, and the exact positions of the arms on the tool are then controlled by the differential movements of the arm ends in the cams.

Abstract: Abstract of the Disclosure An apparatus  for compacting granular molding materials, particularly foundry molding materials, by a surge of  pressure  from a gaseous medium has  a valve arrangement  which  opens  rapidly  due  to  priming  or prestressing of the valve plate by the pressure in the pressure chamber.  When the valve is closed, pressure, built up in the pressure chamber space closed by the valve,  applies  a  force  to  the  valve  member  in  the direction of its open position.  The valve member is held closed  by   a   holder   arrangement.    Following   the development of a predetermined pressure in the pressure chamber, the holder arrangement releases the valve member such that the pressure in the pressure chamber forces the valve member to its open position opening the pressure chamber passage and permitting the pressure medium to surge onto the surface of the molding material.  This apparatus is suitable for all high-stressed gases which must be released suddenly.
