Title: Rocket injection head forced cooling - is ensured by propellant small-bore channels for high velocity flow
Inventor: STERNFELD HANS DIPL ING
IPC: F02K9/52
Filed: 1976-10-02
Abstract: The cooling of the bottom plate in combustion chamber of rocket engine carrying the injection head is due to high-velocity flow of one component of the propellant, such as fluorine. The injection head is formed by the sandwich of (6-8), the latter of which has a ring-type predistribution chamber (25) with inlet connector (5). The chamber communicates with the distribution chamber (22) in plate (7). The propellant component fed through line (4) passes chamber (18) to be injected into the combustion chamber through nozzles (19), while the other ccomponent supplied through connector (5) is uniformly spread by pre-distribution chamber (25) for flow into chamber (22) and then to the nozzles (19). The small cross section of lines (28) ensures that the propellant component flowing in it takes up the heat from the bottom plate (9) and thus prolongs its service life.

Title: Stochastic signal analysis system - operates by mixing test signal with standard search signal and evaluating difference frequencies produced
Inventor: THELEN PAUL
IPC: G01R23/02
Filed: 1976-10-29
Abstract: A method is used for determination of the frequencies present in a stochastic mixture. It depends on scanning the signals with a search signal of known frequency characteristics and analysing the difference frequencies produced in the scanning process. It finds particular application in the continuous monitoring of variations in the diameter or cross-section of a textile thread produced by a spinning machine. The output signal from a probe is fed to an adder (11) which also receives the output from an oscillator (15). The adder output is rectified (17) and smoothed and fed by way of a low pass filter (19) to a signal evaluator for frequency and amplitude analysis. A control signal is then produced at the output (22).

Title: Safety flooding sensor for mines - has flood damming chambers in valve inlet and-or outlet passages to brake valve sphere vibration
Inventor: HOELTER HEINZ
IPC: E21F5/18
Filed: 1977-01-07
Abstract: The safety flooding sensor is designed to counteract the dynamic loading on the springs and valve seats of flood hose release valves caused by vibration of the valve spheres. The vibrations are avoided or damped and the sphere cannot force itself down to the valve base. Flood damming chambers (10, 11) are formed in the water inlet and/or outlet passage. These chambers brake the reciprocating oscillation of the sphere with the aid of the simultaneously oscillating hydraulic column. This braking force is esp. strong just before the closing of the valve so that the valve sits softly on the surface.
