Title: Rocket motor extendible nozzle exit cone
Inventor: SINGER VICTOR
IPC: B64G1/40
Filed: 1986-08-05
Abstract: An exit cone 10 for the nozzle 14 of a rocket motor 12 is made by folding a sheet stock, preferably metal, arcuate membrane in such manner that the aft or larger diameter region of the membrane may be collapsed for stowage with vastly reduced overall length, reduced maximum diameter, and with substantially increased rigidity in comparison with the fully deployed cone. In the stowed condition, shown in Fig. 2, the material comprising the aft portion of the membrane is situated in multiple layers within the forward portion so that deployment, shown in Fig. 6, is induced by forward-to-aft gas flow of the rocket motor within the cone. A press is used to form fold lines in the membrane prior to folding of the aft portion. <IMAGE>

Title: High temperature continuous viscometry coupled with analytic temperature rising elution fractionation for evaluating crystalline and semi-crystalline polymers
Inventor: HAZLITT LONNIE GENE
IPC: G01N25/14
Filed: 1986-11-27
Abstract: A method and apparatus analyzes a polymer sample to determine the instantaneous intrinsic viscosity and the instantaneous viscosity average molecular weight of the various fractions of the continuous stream of fractionated polymer sample solution. The polymer sample is first precipitated over a cooling temperature gradient to produce a precipitated polymer sample, which is precipitated as a function of its crystallinity, branching configuration or density. The precipitated polymer sample is then eluted over a heating temperature gradient to produce a fractionated polymer sample solution, which is successively measured to produce raw mass detector data and differential pressure data, which data can be stored for subsequent computer analysis. The raw mass detector data is used to produce instantaneous concentration data, and the differential pressure data is used to produce instantaneous specific viscosity data. The instantaneous specific viscosity data for the various fractions is produced using the instantaneous concentration data and the instantaneous specific viscosity data. The instantaneous specific viscosity data is used to produce the instantaneous viscosity average molecular weight of the various fraction.

Title: Detection of faults in diesel fuel injectors by obtaining their vibration velocity signatures
Inventor: HALLIWELL NEIL ANTHONY
IPC: G01H9/00
Filed: 1987-10-05
Abstract: Faults or wear in diesel engine fuel injectors are detected by measuring the vibrational velocity of an external surface of the injector body during one or more injection cycles. The measured velocity values are then compared with a reference value to give an indication of abnormal vibration characteristic. Preferably, the velocity is measured using a non-contact method, for example, using a laser-doppler vibrometer although a conventional accelerometer may be used. The method enables the detection of such faults as blocked or enlarged valve opening, a broken valve spring or a needle that is stuck. <IMAGE>

Inventor: GILL BERNARD WILLIAM
IPC: G06F12/02
Filed: 1989-02-16
Abstract: Data processing apparatus includes a processor 14 and a memory 10 operable in page mode. Each row address from the processor is compared 15, with the preceding row address, held in a register 11.

Title: Adjusting a nominal value of a dimension of an actuator

IPC: H01F21/08
Filed: 1991-02-21
Abstract: An actuator 1.1, the longitudinal dimension of which can be changed by applying an external electromagnetic or electrostatic field, has a soft magnetic and highly magnetoelastic layer 1.6 connected to it. When the longitudinal dimension of the actuator changes, the change in mechanical stress in the layer produces a change in the value of an inductance 1.7. The mechanical stress in the layer is inferred from the magnitude of the inductance 1.7 in sensor electronics 2.3 and the longitudinal dimension of the actuator is inferred from the mechanical stress in the layers. The longitudinal dimension of the actuator is compared with a predetermined nominal value in a comparison device 2.4 and a correcting variable is output by a control device 2.5 when a difference is detected, the correcting variable being predetermined in such a manner that the detected difference disappears. <IMAGE>
