Patent EP-0296735-A2 (EP)
Inventor: AUGUST HENRY
IPC: F42B10/42
Filed: 1988-06-09
Abstract: The overall drag upon a missile body after launch can be reduced and hence the range and average speed of the missile increased by reducing the aerodynamic drag at supersonic velocities attributable to missile hooks (10) which are normally used to attach and launch the missile body from a launcher assembly. After launch a pair of splitter plates (20, 22) are popped up into a position next to each missile hook (10). One splitter plate (20) is positioned in front of the missile hook (10) and a second splitter plate (22) positioned behind the missile hook. The splitter plates are generally planar and arranged so that their planar surfaces are approximately parallel to the fore and aft direction of the missile body (34). In the illustrated embodiment, the splitter plates are erected into an operative configuration with respect to their missile hooks by rotating each splitter plate about a hinge line (36). The splitter plate is biased to assume the erect configuration by means of a torsion spring (42). An electromechanical latch (58) maintains the splitter plates (20, 22) in a folded configuration against the missile body (34) until the missile body has cleared the launch assembly. Thereafter the latch (58) releases the splitter plates (20, 22) allowing the   torsional spring (42) to rotate each splitter plate (20, 22) into an operative configuration. Upon full erection of each splitter plate, each splitter plate is mechanically locked into the erect configuration. In one embodiment a fifty percent reduction in the drag coefficient is realized at supersonic velocities as a result of the splitter plates.

Abstract: A pressure sensor (10) includes a three part package including a main housing member (12) defining two spaced-apart chambers (20,22), a bottom closure member (18) providing the bottom wall of one of the chambers, and a top cover member (14) hermetically sealing the two chambers from one another and including a port (34) for admission of gases into one of the chambers. A pressure sensing element (32) is disposed in the chamber having the port and mounted on the bottom closure member, and a signal processing element (36) is mounted in the other chamber. Electrical connections between the two elements are by means of leads (47) which extend into each chamber and pass through an inner wall (30) separating the chambers. A low temperature differential between the two elements is provided by extending (47a) one of the leads from the one chamber to a position directly underlying and in intimate contact with the bottom surface of the signal processing element in the other chamber. 
Additionally, the bottom closure member is of a high thermal conductivity material and extends along the bottom of the main housing member to beneath the other chamber.

Abstract: Process for fractionating phosphatide mixtures into two or more fractions which are enriched in one or more of phosphatidyl choline (PC), phosphatidyl ethanolamine (PE), phosphatidyl inositol (PI) and phosphatidic acid (PA) by carrying out extraction steps using alcoholic solvent in which the solubilities of PC, PE and PA are controlled by suitably adjusting the acidity of the solvent, the pH being adjusted to above 8 for solubi­lizing PC and PE and to below 5 for solubilizing PA. PI is substantially insoluble in the solvent used in the process and thus is mainly recovered in the extraction residue. Further parameters influencing the solubility of the components of the phosphatide mixtures to be frac­tionated are water content of the alcoholic solvent, temperature and choice of bases and acids for adjusting the pH. For further separating fractions rich in PC and PE di- or trivalent metal salt solutions are used.

Abstract: A catheter assembly (1d) and method for catheterization provides a means by which the curved configuration at the distal portion (14) of a catheter can be varied while the catheter system remains in the patient. The catheter, having a predetermined curve at its distal end is received within a sheath (28) that can be advanced over the distal end to tend to straighten the curve in the distal end of the catheter. The extent to which the sheath is advanced over the curved distal portion of the catheter controls the degree to which the catheter is straightened. The position of the sheath relative to the catheter can be adjusted while the catheter is in the patient, thereby enabling change in catheter shape without requiring catheter exchanges. For example, the system enables right and left coronary angiographic procedures to be performed without changing catheters. Left ventricular studies also can be made without catheter exchanges.
