Abstract: A catalytic combustion chamber is provided with at least two catalytic combustion zones arranged in flow series. In a first mode of operation fuel is supplied from first fuel injectors, positioned upstream of the first catalytic combustion zone, into the catalytic combustion chamber and is burnt in the first catalytic combustion zone in order to preheat the subsequent catalytic combustion zones. In the second mode of operation the supply of fuel to the first fuel injectors is reduced and fuel is supplied from second fuel injectors positioned between the first catalytic combustion zone and the second catalytic combustion zone into the space between the first catalytic combustion zone and the second catalytic combustion zone. This prevents the first catalytic zone becoming overheated, and reduces the possibility of the second and third catalytic combustion zones becoming overheated and allows the optimum catalyst to be selected for the first catalytic combustion zone.

Abstract: A detonation cycle gas turbine engine includes a turbine rotor contained within a housing. Exhaust ports of respective valveless combustion chambers on opposite sides of the rotor direct combustion gases toward the turbine. The chambers are connected by a valveless manifold fed with fuel and oxidizer. When combustible gases are detonated by an igniter in one of the combustion chambers, the back pressure from the detonation shuts off the fuel and oxidizer flow to that chamber and redirects the fuel and oxidizer to the opposite chamber, where detonation occurs, the process repeats cyclically. Power is taken off the rotor shaft mechanically or electrically.

Abstract: A reverse cycle defrost or water defrost type ice-maker refrigeration system includes a programmable controller which initiates a freezing cycle in which water is pumped for application to the chilled surface of an evaporator for freezing. All water that fails to be frozen absorbs minerals from the frozen water and is returned to the sump. The programmable controller terminates replenishment of water removed from the sump substantially prior to completion of the freezing cycle so that the sump level falls and the mineral content of water in the sump increases substantially. The ice is harvested at the end of the freezing cycle by hot refrigerant gas from the compressor directed to the evaporator or warm water while the sump is being drained and subsequently refilled prior to the initiation of a subsequent cycle of operation. The operation is energy efficient since water is saved and a reduced amount of water is used and a reduced amount of previously refrigerated water is disposed of by drainage of the sump.

Abstract: In a CO.sub.2 refrigerant cycle, a lubricating oil for a compressor has a compatibility relative to CO.sub.2 refrigerant, and the compatibility of the lubricating oil relative to the CO.sub.2 refrigerant at a pressure lower than a critical pressure of the CO.sub.2 refrigerant is lower than that at a pressure higher than the critical pressure of the CO.sub.2 refrigerant. Thus, in a low-pressure side such as an accumulator of the CO.sub.2 refrigerant cycle, because a liquid lubricating oil is separated with a liquid CO.sub.2 refrigerant, only the lubricating oil can be readily introduced into a suction side of the compressor, and it can prevent the liquid CO.sub.2 refrigerant from being sucked into the compressor. As a result, it can prevent a damage to the compressor while preventing deterioration of coefficient of performance of the CO.sub.2 refrigerant cycle.

Abstract: A process for effectively bonding arbitrary size or shape substrates. The process incorporates vacuum pull down techniques to ensure uniform surface contact during the bonding process. The essence of the process for bonding substrates, such as glass, plastic, or alloys, etc., which have a moderate melting point with a gradual softening point curve, involves the application of an active vacuum source to evacuate interstices between the substrates while at the same time providing a positive force to hold the parts to be bonded in contact. This enables increasing the temperature of the bonding process to ensure that the softening point has been reached and small void areas are filled and come in contact with the opposing substrate. The process is most effective where at least one of the two plates or substrates contain channels or grooves that can be used to apply vacuum between the plates or substrates during the thermal bonding cycle.
