Title: Method and an arrangement for distance measurement using the pulse transit time principle
Inventor: ELLE ANDRE
IPC: G01S7/52
Filed: 1993-06-01
Abstract: For the measurement of distance using the pulse transit time principle the received signal produced after each trans-mission of a pulse is stored as an echo profile and the effective echo is determined from the stored echo profile. In order to suppress recurrent interfering signals a stationary threshold profile adapted to the measurement environment is formed and employed for each evaluation of a stored echo profile. In order to take into account fluctuations in the properties of the received echo profile rapidly without necessitating a modification in the stationary threshold profile for this, from a stored echo profile a floating threshold profile is generated in the form of a monotonously descending curve. From the mutually corresponding values of the floating threshold profile and of the stationary threshold profile the respectively larger value is utilized for the formation of a resulting threshold profile, which is employed for each evaluation of stored echo profiles.

Title: Method and apparatus for determining turbine blade deformation
Inventor: FERLEGER JUREK
IPC: F01D5/06
Filed: 1993-07-05
Abstract: 57,270 ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for determining the amount and type of permanent deformation experienced by a turbomachine blade.  According to the invention, small holes are drilled in at least three blades of the blade row.  One hole is drilled in the inlet face of the blade shroud and another hole is drilled in the inlet face of the blade root. In addition, third and fourth holes are drilled in the exit face of the shroud and a sixth hole is drilled in the exit face of the root.  Measurements are taken between the shroud holes on the middle blade and the root holes on the outer blades in the row on both the inlet and exit faces.   The measurements are use to form triangles indicating the blade geometry.  By comparing the changes in these triangles after substantial operating time,  both the type and amount of permanent deformation can be determined.

The monomers have the formula:   wherein n is 1 to 5, m is 1, R is hydrogen or alkyl having from 1 to 4 carbons; and R f is linear or branched chain perfluorinated alkyl having from 1 to 20 carbons, or an oxaperfluorinated polyether, having from 4 to about 60 carbons, and the resultant prepolymers have the formula:   wherein n is 1 to 5, m is 1, R is hydrogen or alkyl having from 1 to 4 carbons, R1 is alkylene or isoalkylene having 2 to about 5 carbons, R f is linear or branched chain perfluorinated alkyl having from 1 to 20 carbons, or an oxa-perfluorinated polyether, having from 4 to about 60 carbons; and x is 2 to about 250. The monomers are prepared by the reaction of fluorinated alkoxides with aryl sulfonate derivatives of 3--hydroxyalkyl oxetanes, e.g., the p-toluene sulfonate derivative of 3-hydroxymethyl-3-methyl oxetane or of 3,3-bis(hydroxymethyl)oxetane. A high yield of the oxetanes having pendant perfluorinated alkoxy side chains is obtained. The fluorinated alkoxy oxetane monomers of this invention can be readily polymerized in the presence of Lewis acid catalysts and polyhydroxy aliphatics to obtain high yields of hydroxyterminated prepolymers having molecular weights from 1,000 to about 30,000, and a polymer backbone resulting from the opening of the oxetane ring.

Title: Fluid distribution device
Inventor: SEGURA SALVADOR SILVIA B
IPC: F15B21/0423
Filed: 1993-07-22
Abstract: ABSTRACT         The device comprises a block provided with two ducts, each of which is designed to act either as the intake or outlet duct for the pressurised fluid coming from or going to the brake motor.  Each of these ducts is connected to two one-way valves of which two of the valves permit passage of the fluid coming through the corresponding duct, and convey it to a pressure valve which is controlled by a valve.  The fluid emerges from the latter valve through a duct, and after having passed through an external cooler, the fluid then returns via another duct which communicates the supply pressure to a valve.  This latter duct communicates at its outlet with another duct connecting the one-way valves.  These valves do not permit the passage of the fluid obtained from the ducts respectively.

Alternatively, the electron emitting element includes an electron emitting portion connected to a voltage supply through a thermally cut-off member, and an electron emitting portion forming film which includes a thermally connecting member. In this case, after cutting off the electrical connection in that electron emitting portion on which the electron emission characteristic has been found not normal, the electron emitting portion forming film is connected to the voltage supply for forming another electron emitting portion in the film.

Title: Filling unit preventing the overfilling of small tanks or the like
Inventor: TYREE LEWIS JR
IPC: B67C11/02
Filed: 1991-12-23
Abstract: Filling units (11) for supplying small tanks or the like with gasoline, kerosene, or other flowable materials which attach to an inlet to such a tank (13). When the filling unit is in a fill position, a displacer section (21) occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level (62) in a funnel portion (19) of the filler. Thereafter, manipulation of the displacer section (21) vertically within the tank, as for example by sliding a section of the overall unit upward, accommodates all the liquid remaining in the funnel up to such predetermined level within the tank by occupying the volume previously occupied by the displacer section and thereby completing the filling of the tank to a full condition without any spillage. The overall unit may be such that it is intended to be removed from the tank after each filling operation, or it may be designed to fit permanently within a wide-mouth tank inlet (89) and to be movable downward to a storage orientation which allows the unit (87) to remain mounted in the tank inlet and covered by the protective cap (117) that normally screws onto the inlet opening to close it.
