Abstract: A loop four-wave mixing phase conjugator that can be used with depolarized signal beams comprises a polarization separator (10), a polarization mixer (19), an optical diode (20), a gain medium (22) and relay optics (14, 16) that together form a unidirectional laser resonator. In operation, the polarization separator separates a signal beam (ε 1 ) into orthogonally polarized signal beam components (ε 11 ) and (ε 12 ) and directs them to a nonlinear medium (12). The components propagate through the nonlinear medium and emerge as loop beam (ε 2 ), with orthogonally polarized components (ε 21 ) and (ε 22 ). The polarization mixer mixes the energy from the two orthogonally polarized loop beam components, and relay optics direct the loop beam components back to the nonlinear medium at an angle with respect to the input beam. The loop beam components intersect and optically interfere with signal beam components (ε 11 ) and (ε 12 ) in the nonlinear medium to form gratings (18). The optical diode and gain medium are positioned in the optical loop so that an oscillation beam (ε 3 ) builds up from optical noise in the resonator and oscillates in a direction counter to the propagation direction of loop beam components (ε 21 ) and (ε 22 ). A portion of oscillation beam (ε 3 ) is transmitted by the gratings, and exits the optical loop as an output beam (ε 4 ). (ε 3 ) is phase conjugate to the input beam (ε 1 ) in both the spatial and polarization senses.

Abstract: The system is esp. for oxygen from a bottle to a respiration hose, having an electrically-operated valve controlled by a sensor for the pressure drop occurring on inhalation. The time for which the valve is open and thus the amount of gas delivered are adjustable dependent on the oxygen requirement. The values delivered by the sensor indicating frequency of respiration and thus the time interval between two successive inhalations are evaluated by a computer (8), and used to control the time for which the valve (9) is open, and if desired also the flow rate per unit of time. On starting up, the sensor data can remain unevaluated for a short time at least. The computer can be arranged to detect the steepness of the increase in depression from the sensor deflection per unit of time, so that with short inhalations the valve opens for a relatively long period.

Abstract: A cooking machine control system for controlling the
consumption of fuel by gas cooking machines, and gas flow
valves usable in such cooking machine control systems. The
cooking machine control system maintains the cooking surface
of the cooking machine at an appropriate standby temperature
when no food is being cooked, brings the cooking surface to an
appropriate temperature to cook the food, and then returns the
cooking surface to the standby gas flow rate. The system can
be returned to the standby gas flow rate either after the
cooking gas flow rate has been provided for sufficient time
for the food to have cooked or after the temperature of the
food has reached the desired level. With the cooking machine
control system in the standby mode, when food is to be cooked
a switch is actuated, applying a start signal to cause a valve
to open the cooking flow rate path to cook the food, following
which the valve returns the system to the standby mode. In
another embodiment, the cooking machine control system
includes a first gas pipe which provides gas to each burner of
the cooking machine at the standby gas flow rate and a second
gas pipe which in the standby mode is closed by a valve. When
food is to be cooked, the start signal opens the valve to
provide gas to each burner at a rate sufficient to bring the
cooking surface to the appropriate cooking temperature.
