Abstract: A distributed balanced frequency multiplier 11 has a transmission line 25 that is configured using lumped elements having connection points 29 for inputting signals. Connected to each connection point is the output from a non-inverting amplifier 19 which amplifies a signal applied thereto. A second transmission line 27 is configured also using lumped element 13 techniques and has connection points 42 for receiving an inverted amplified signal whose odd harmonics are 180° to the non-inverting amplified signals. The signal that is to be amplified is carried to both the non-inverting and the inverting amplifier by a third transmission line 29 that also uses lumped elements 13 distribution techniques to create a transmission line. The output of the first transmission line and the second transmission lines are tied together so that the odd harmonics due to the inverting amplification stages cancel and the even harmonics are additive, thereby achieving an effective multiplication of the input signal.

Abstract: In the process, the energy exchange between warm space air and cold air takes place by self-convection of the air by means of a chute arranged in the space, which has cooling surfaces in its upper part, on which the warm space air entering cools down and flows downwards because of the specific weight difference. The cooled air leaves the chute at the lower end in a laminar flow and then spreads out in the space in a continuous cooling layer. The air leaving the chute can also be diverted into a hollow floor. It is possible to add to the cooled air flow moved by gravity disturbance air produced by a fan, which then results in turbulence.

Abstract: Corn kernels packaged within an elongate bag (10) can be popped with microwaves and served in the bag. During popping, part of the bag's longitudinally-extending back seal opens and permits vapors to vent from the bag. After the kernels are popped, the back seal (28) is fully opened to transform the bag (10) into a serving bowl having an opening defined by the edges of bag material previously forming the back seal (28). The bag (10) is made from a laminate of two paper layers (38,40) with a susceptor (36) between the two paper layers (38,40) at a location where the bag (10) will contact the floor of the microwave oven. Alternatively, instead of using two layers of paper, a single layer of paper surrounding a layer of polymeric barrier material can be employed. The back seal (28) is formed from side edges of a web (30,32) of the laminate either by bonding the inner layers of the web edges together or by bonding the inner layer of one web edge to the outer layer of the other web edge. If the innermost layer of the bag is made of a polymeric barrier material, the back seal can be formed by pressing the web edges together under heat and pressure. If the innermost layer is paper, an adhesive must be applied to the web edges before they are pressed together, usually at elevated temperatures. A method of preparing the package of corn kernels is also disclosed.

Abstract: Geothermal energy may be recovered through an underground well drilled to a depth approaching the earth's magma by circulation of injected heat transfer fluids flowing along separate parallel paths within closed loops (24, 35; 40, 42) extending into the well (12). One or more of the injected fluids may be conducted by a heat transfer portion of the loop establishing a lower heat absorbing zone (22) within the well exposed to superheating conditions at ultra-deep depths. Circulation of the fluid within said heat transfer portion may be prolonged to efficiently absorb heat and heat loss may be minimized by heat exchange relationships between the paralle flow paths above the lower heat absorbing zone.
