Abstract: Docket 2449 METHOD AND APPARATUS FOR PUMPING       BLOOD WITHIN A VESSEL                          Abstract of the Disclosure A dynamically augmenting pump system incorporates a sealed liquid-filled catheter which is inserted into a vessel such as an artery, and the pump system is operated in timed relation with the heart to aid the heart during episodes of impairment or failure of cardiac function by producing higher frequency pulsation or pressure waves within the blood during diastole and during the isometric contraction period of the heart. This frequency of pulsation is adjusted to the dynamic transmission characteristics of a selected circulatory subsystem, such as the coronary vascular system, to assure the transmission of a maximum of pulsatile energy into the subsystem. The catheter provides energy to maintain adequate blood flow through the healthy part of the myocardium and has a passage for injecting successive quantities of medication into the coronary arteries. The pump system also functions to penetrate the ischemic myocardial tissue with arterial blood and medication. The pump system may also be used to provide enhanced perfusion for other parts of the systemic circulatory system, for example, to prevent such detrimental effects as renal failure. Any one or combination of the functions may be used depending on the special medical conditions of the patient.

Abstract: Abstract of the Disclosure A two input flip- lop circuit is successively triggered to alternate states by two series of electrical signal pulses, each of which corresponds to one of two rotating members and is of a frequency proportional to the rotational speed of the corresponding rotating member.  The flip-flop circuit output signals are applied to an averaging filter circuit that produces an output ramp signal that increases substantially linearly in amplitude as a function of change of phase displacement of the pulses of the two series of electrical signal pulses and remains at a constant value when the phase displacement of the pulses of the two series of electrical signal pulses remains constant thereby indicating an equality of the rotational speeds of the two rotating members.

Vesiculated fibrils of crosslinked polyester resin of length 50 µm - 5 cm, diameter 1 µm - 2mm and aspect ratio of 10-50 are prepared by pouring into water with stirring a selected solution in unsaturated monomer of a carboxylated unsaturated polyester resin of acid value 10-90 mg KOH per g., the water containing both a base having a pKb value of 8 maximum and a dispersion stabiliser, and initiating polymerisation.  The polyester solution is selected for suitability for fibril formation by means of a buoyancy test.    The fibrils are useful in a number of applications, for example, as fillers for paints and putties, viscosity modifiers in liquids and replacements in some applications for fibrous mineral extenders such as asbestos.

Abstract: Abstract of the Disclosure An apparatus and method of using the same to separate a heavy crude oil emulsion into gas, brine and oil, as the emulsion flows longitudinally through first, second, and third elongate zones.  The crude oil emulsion is heated while in the first and second zone allowing the free brine and gas to separate therefrom,  The heated crude oil contain-ing the remaining emulsified brine flows to the third zone to be subjected to a high potential electrical field which coalesces the droplets of brine remaining therein into drops.          These larger drops of brine flow downwardly by gravity to the bottom of the third zone,  Oil substantially free of brine now in the top layers flows from the third zone over a wall into a reservoir, with the wall serving the dual function of maintaining the liquid level in the third zone at an elevation where the electrodes that supply the high potential electrical field are at all times immersed in the oil, and also prevent-ing brine-free oil in the reservoir from comingling with oil that is being treated in the third zone.  Gas separating from the emulsion accumulates in the upper portion of the first, second and third zones and water in the lower portion of the zones, The gas and brine that so accumulate are withdrawn therefrom to desired external location as the treating operation proceeds.  Oil may be intermittently or contin-uously discharged from the reservoir without effecting the liquid level in the third zone.
