Granted: 2005-06-30
Abstract: A method for the regulation of combustion air when wood is burned in a heat-storing fireplace in which all combustion air (1) is supplied from below a grate (2) into a firebox. When a wood charge (4) is being ignited, a substantial proportion of the combustion air (1) is supplied as auxiliary primary air (5) through the middle area of the grate (2) under the wood charge and some of the combustion air is supplied into the firebox as secondary air (6). After the wood charge has been kindled or when more wood (7) is added on top of glowing embers (8), the amount of auxiliary primary air is limited, some of the combustion air is directed as main primary air (9) under the wood charge mainly to the edge areas of the wood charge while most of the combustion air is supplied as secondary air (10) into the firebox. <IMAGE>

IPC: B25D9/26
Filed: 1987-08-06
Abstract: A hydraulic percussion device comprises a housing defining a longitudinal cylinder, a piston longitudinally reciprocal in the cylinder and subdividing same into a front compartment and a rear compartment, and a tool engageable longitudinally with the piston at the front compartment. The compartments are alternately and oppositely hydraulically pressurized to move the piston forward to strike the tool while traveling at an end speed and to move the piston backward away from the tool, the rate of alternation being a frequency parameter and the speed being a force parameter. A controller varies at least one of the parameters by detecting how much the piston rebounds from the tool after striking same and operating the control means in accordance with how much rebound is detected. How much the piston rebounds can be detected by sensing the pressure in one of the compartments immediately after the piston strikes the tool. As rebound increases the pressure in the rear compartment increases relative to a set point or pressure in the front compartment decreases relative to a set point, and vice versa. Rebound can also be detected by sensing the pressure in one of the compartments and at one of the sides of the source and operating the control means in accordance with the differential between these sensed pressures.

Title: Semiconductor device wherein a first flat surface of a semiconductor chip is jointed to a second plat surface of a heat sink by a fusible bonding material
Inventor: STOECKERT A J
IPC: B23K1/20
Filed: 1974-09-09
Abstract: A flat surface of a semiconductor chip is soldered to a relatively larger flat surface of a heat sink by forming a plurality of closely spaced grooves in the flat surface of the heat sink, coating the flat surfaces of the chip and the heat sink with nickel, disposing solder between the coated surfaces of the chip and the heat sink, and heating the surfaces until the solder melts. The grooves in the heat sink prevent the entrapment of gas bubbles between the chip and the heat sink, thereby providing good thermal conductivity and a relatively low electrical resistance between the chip and the heat sink.
