Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to blood pumps for use, for example, in cardiopulmonary bypass procedures, left ventricle assist procedures and hemodialysis.  In its most elementary form, the blood pump comprises an elongated driver balloon and a similar blood pumping balloon positioned side by side in a rigid housing preferably having a one-way air valve that permits only air flow out of the housing.  Alternatively, the air valve may be replaced by an open vent.  Sloping end portions of the balloons terminate in ports offset from the balloon axes and minimize folding and/or rubbing during use.          The driver balloon is provided with one port for coupling to a pressure-vacuum source, and the blood pumping balloon is provided with an inlet port and an outlet port.  Both balloons are of such a cross-sectional size and construction as to provide non-occlusive action by the blood pumping balloon.         When the balloons are used to assist a conventional roller pump, one-way valves in or associated with the blood pumping balloon are not necessary.  The one-way air valve in the housing permits the reduction of deflation time of the driver balloon when it is coupled to a vacuum source, facilitates counterpulsation, prevents the introduction of gas into the blood stream in the event of a failure of the blood pumping balloon and prevents actuation of the blood pumping balloon in the event of failure of the driver balloon.

Abstract: ABSTRACT OF THE DISCLOSURE         The electronic tone ringer of the present invention comprises a rectifier circuit connected across the tip and ring leads of a telephone loop to provide a d.c. voltage.  The d.c. voltage is connected through a timing circuit to the inputs of a sounding device.  The timing circuit includes a timing network, which is connected across the d.c. voltage for establishing a predetermined time delay.  The timing network controls a first transistor which in turns controls a second transistor.  The second transistor is connected across the input of the sounding device so that prior to the expiration of the predetermined time delay, the second transistor shunts the inputs of the sounding device to assure that the sounding device is not erroneously activated by a short duration transient voltage across the tip and ring leads.

Abstract: ABSTRACT            It is known the dynamic membrane process in which dynamic membrane formation and further rejection of the dissolved substances and/or fine particle separation from a solution are made on a motionless porous support at the transmembrane pressure in the range of 400-I000 psig.Frequently,in addition to this high transmembrane pressure, a high velocity circulating cross-flow  feed stream is used in order to achieve high permeate flux.To carry out this feed circulation an additio-nal energy consumption is required. In this invention the dynamic membrane formation and further rejection and/or particle separation by previously formed dynamic membrane are carried out on a rotating porous support  that allows to achieve both dynamic membrane formation and further rejection of dissolved substances and/or fine particle separation from solution by previously formed membrane  at forty- to hundredfold  lower transmembrane pressure(7-20psig. and without or  under very low cross-flow stream of the feed solution. By this,the permeate flux,i.e. specific productivity of the dynamic membrane,is in the same range as for high transmembrane pressure and high velocity cross-flow feed stream dynamic membrane process carried out on a motionless porous support.

Abstract: HEAT EXTRACTOR                 ABSTRACT OF THE DISCLOSURE           A method and apparatus for efficiently recovering heat from a gas stream such as discharged flue gas.  The gas stream is countercurrently contacted with a liquid medium in two stages.  A first countercurrent contact stage is between a partially cooled gas stream and cold liquid medium in a bed of packing through which the cold liquid medium flows downwards and the partially cooled gas stream flows upwards, so that a warmed liquid medium and fully cooled gas stream are pro-duced.  The second countercurrent contact stage is between the warmed liquid medium derived from the first contact stage and the hot initial gas stream in a plurality of parallel vertically oriented passages.  The warmed liquid medium flows downward on the inner walls of the vertically oriented pas-sages as a thin liquid film, while the hot initial gas stream flows upwards within the vertically oriented passages, so that a fully heated liquid medium and the partially cooled gas stream are produced.  The second contact stage accomplishes high direct contact heat transfer with low mass transfer, so that minimal heat is lost as heat of vaporization of liquid medium evaporated into the gas stream.  The fully heated liquid medium is passed in indirect heat exchange with a fluid, so that the liquid medium is cooled and the fluid, which may be water, air, or a process fluid stream, is heated.

Abstract: ABSTRACT OF THE DISCLOSURE     A buoyancy system for large scale underwater risers is provided, comprising a plurality of canisters. Each of the canisters extends partially around the circumference of a riser -- usually, two  canisters and the support structure surround a riser -- and a plurality of canisters is associated with each riser section.  Air is injected into the lowermost  canister or canisters, at a pressure sufficient to displace the contained water within the canister; and when the water level within a canister is lowered sufficiently that a port in a cross connected tube is uncovered, the compressed air enters the tube and travels upwardly to the next canister above, where the unwatering sequence is repeated.  Because very great depth can be accommodated --3,000 meters or more -- provision is made for reflooding the canisters in the event of an emergency.  Additionally, because of pneumatic considerations, different  configurations of cross tube are provided for installation in the canisters at varying depths.  The support structure for the canisters, and the plastics materials of which the canisters are made -- cross linked polyethylene is preferred -- preclude permanent deformation and damage to the canisters during storage or upon impact with an unyielding body or surface.
