Patent number: 5388541Abstract: A tanker ship has upper and lower tanks for carrying cargo. The upper and lower tanks are separated from each other by an intermediate deck. The lower tank is filled with cargo to the intermediate deck such that the cargo is slightly pressurized and there is no ullage space. As the tanker sails, the cargo in the lower tank is likely to change pressure due to temperature changes. These pressure changes are detected by a pipe extending from the lower tank through the intermediate deck up to an ullage space in the corresponding upper tank. A siphon is used to transfer cargo between the upper and lower tanks to equalize the pressures. In the event that the lower tank is breached, sensors are used to detect the resulting drop in pressure from the lower tank cargo. The sensor system provides a warning to the crew, closes the siphon to prevent cargo transfer from the upper tank to the lower tank and opens an auxiliary pipe located in the upper portion of the lower tank.Type: GrantFiled: September 15, 1992Date of Patent: February 14, 1995Inventors: Allen E.

Patent number: 5388572Abstract: A dry powder inhalator for delivering a precise dose of a medicament contains a mesh disc impregnated with a series of spaced, medicament doses about the disc periphery. The inhalator is armed by manually retracting a finger pull extending downwardly from the bottom of the inhalator housing or rotating the bottom of the housing. The user inserts a mouthpiece on the housing into the mouth and inhales. This causes a chamber in the housing under a diaphragm to evacuate, thereby pulling the diaphragm down onto a knock out lever. The pivoting of the lever enables release of a piston into a cylinder which first compresses, and then dispenses a reduced volume of air at high pressure in a burst up through the medicament disc. When the burst of air hits the impregnated disc, the dose is forced out of the mesh's interstices, producing a cloud of the drug in its powdered form, which is inhaled by the user.Type: GrantFiled: October 26, 1993Date of Patent: February 14, 1995Assignee: Tenax Corporation (a Connecticut Corp.)Inventors: Paul Mulhauser, Jeffrey Karg, Thomas Foxen, Christopher J.

Patent number: 5388575Abstract: An automatic controller utilizes a pulse oximeter signal to regulate the oxygen mixture output, peak expiratory end pressure, and inspiratory ventilation time from a positive pressure respiratory assist ventilator. The pulse oximeter senses a patient's hemoglobin saturation and pulse rate by an optical sensor to develop a signal which is used by calculator to determine the patient's corresponding partial pressure of arterial blood. The calculated partial pressure of arterial blood is then used by the calculator in determining the level of inspired oxygen, peak expiratory end pressure, and inspiratory ventilation time provided to the patient. The calculator generates a signal to control the level of inspired oxygen, expiratory end pressure, and inspiratory ventilation time output from a positive pressure respiratory assist ventilator.Type: GrantFiled: September 25, 1992Date of Patent: February 14, 1995Inventor: John C.

Patent number: 5388576Abstract: A pulmonary resuscitator is set forth of the type having a compressible bladder to be depressed to supply air to a mask. Both the compressible bladder and mask have integral therewith a network of inflatable tubes which when pressurized resiliently rigidify the bladder and mask to establish nominal erected bladder and mask shapes. The bladder has an inlet check valve and the mask has an outlet check valve where the outlet check valve utilizes a flapper valve for permitting flow of fluid into the mask upon depression of the bladder. Exhaust ports are located adjacent the flapper valve and are closed by the flapper valve when the bladder is depressed. The exhaust ports are opened when the flapper valve closes as the bladder returns to its nominal shape after being depressed. An air spring contained within the bladder chamber is in fluid communication with the network of inflatable tubes and through limiting orifices controls the rate at which the bladder returns to its nominal shape after depression.Type: GrantFiled: August 13, 1993Date of Patent: February 14, 1995Assignee: Grayco, Inc.Inventor: Thomas C.

Patent number: 5388579Abstract: A fetal electrode product for transmitting signals indicative of fetal heart rate from a fetus to a monitor. A drive mechanism slides and rotates a holder--to which are attached, at opposite ends, a fetal spiral electrode (FSE) and a reference electrode--to secure the FSE to the fetus. The drive mechanism has a solid drive rod, with at least two regions of different diameter defining the torque versus angular deflection characteristics of the drive rods and a clutch connected to the drive rod and imparting translation and rotation to the holder. The clutch is sufficiently pliable to slip over the reference electrode when the holder resists rotation. The drive rod, a handle, and the clutch are integrally molded together to form the drive mechanism and each has a channel transporting a twisted wire strand, which includes an untwisted length to facilitate removal of the FSE from the fetus, from the electrodes to a connector.Type: GrantFiled: September 23, 1993Date of Patent: February 14, 1995Assignee: Graphic Controls CorporationInventors: Edward Dowd, Joseph O'Neill, David M.
