Title: Thermally activated trigger device
Inventor: HARTY RICHARD B
IPC: G21C9/033
Filed: 1986-09-05
Granted: 1990-11-06
Abstract: Abstract of the Disclosure A thermally activated trigger device 10 comprises a pressurized closed vessel 11 with a piston 12 slideably mounted in it to divide it into two compartments 14 and 16.  A fluid such as an inert gas is contained within the compartments at substantially the same pressure.  One end of one of the compartments has venting means 24, such as a normally closed pipe which vents the fluid from the compartment once the pipe becomes open by rupture of melting at an elevated temperature.  The resulting pressure difference between the compartments on venting of the fluid moves the piston which is connected to an actuator means for performing a desired control or safety shut-down function.  The trigger device is useful for performing many control and safety shut-down functions, particularly for rendering a nuclear space reactor subcritical upon reentry to the earth's atmosphere.

Title: Recombinant dna plasmid for xanthan gum synthesis
Inventor: CLEARY JOSEPH M
IPC: C12P19/06
Filed: 1987-02-06
Granted: 1991-07-16
Abstract: TITLE OF INVENTION RECOMBINANT DNA PLASMID FOR XANTHAN GUM SYNTHESIS            ABSTRACT OF THE DISCLOSURE         Described is a DNA fragment containing some essential genetic material for xanthan gum synthesis. The fragment is isolated from gum-producing Xanthomonas campestris and inserted into a cloning vector using recombinant DNA technology.  A resulting recombinant plasmid, pCHC3, restores xanthan gum synthesis to non-xanthan gum forming (non-mucoid) mutants, increases xanthan gum yield in gum-producing strains by gene augmentation, and increases the pyruvate content of the obtained xanthan gum.  The invention encompasses other DNA fragments isolated from gum-producing X. campestris and which, after appropriate manipulations, restore xanthan gum synthesis in substantially the same fashion as the fragment of pCHC3.

Filed: 1988-03-04
Granted: 1991-08-13
Abstract: Abstract A procedure and an apparatus for the autonomous, onboard determination of an inertial attitude reference (attitude angle T) for a guided projectile is so designed that it can be implemented with the least possible use of sensors and, as far as possible, independently of the instantaneous position of the projectile (12) relative to the apogee (A) of its ballistic trajectory (B).  To this end, reference is made to the trimmed-flight behaviour that is available for the control algorithm of an autopilot (13), according to which the satisfaction of the aerodynamic equations for trimmed flight--which is to say the flight state after entry into a stable flight position on the ballistic trajectory (B)--brings about a specific control-surface position (e) as a function of local conditions and this, together with the dynamic pressure (p) as a parameter results in a defined attitude angle (T) in space.  In order to take into account the variation of dynamic pressure (p) from the instantaneous flight altitude (h) and, optionally, other local conditions, a defined change in the position (e) of the control surface that is a temporary departure from the stable flight state is initiated, and the resulting change in the pitch attitude (Ts) is integrated by means of the pitch-rate gyro incorporated in the autopilot (13).  This relationship is a measure of the altitude (h) and is thus available as a parameter, in order that the inertial attitude angle (T) as a function of the instantaneously measured dynamic pressure (p) at the autopilot (13) can be read out from a characteristic curve memory (19.2) free of any influence exerted by density.

Title: Pressure regulating valve
Inventor: LOLIGER WILLI
IPC: F16K31/126
Filed: 1988-06-21
Granted: 1991-08-13
Abstract: Abstract Pressure regulating valve To regulate the pressure of a liquid, particularly in a high-temperature pasteurizer or sterilizer, the valve comprises two chambers separated by a membrane integral with a valve pin.      The pressure on the side of the liquid to be treated is always higher than that of the control air by virtue of the fact that the surface on which the compressed air acts is larger than that contacted by the liquid.  This enables the installation to be kept sterile even in the event of a leak in the membrane.      The valve is particularly suitable for ultra-high-temperature sterilizers with direct injection of steam.            Fig. 1
