Abstract: Method of utilizing process gas containing sulphur dioxide obtained from discontinuous processes, in the manufacture of sulphuric acid in a contact plant. When practicing the method according to the invention, all of the process gas, or a predetermined amount thereof, is withdrawn from the process during process operational periods, in which gas containing sulphur dioxide is generated, and the sulphur dioxide contained by the withdrawn gas is at least partially separated therefrom to form a liquid phase containing the amount of sulphur dioxide separated. The gas partially freed from sulphur dioxide, together with any non-withdrawn process gas, is passed to the contact plant for manufacturing sulphuric acid. Stored absorption liquid is utilized during those periods in which no process gases are produced or passed to the contact plant or in which the process gases contain insufficient sulphur dioxide. Sulphur dioxide is stripped from the liquid phase with the aid of a carrier gas, and the carrier gas, together with the stripped sulphur dioxide, is passed to the contact plant. This enables a required amount of gas and sulphur dioxide to be constantly supplied to the contact plant, even during those periods when the discontinuous process does not produce a sulphur-dioxide-containing gas or produce a gas having an insufficiently high sulphur-dioxide amount.

Abstract: One end of the retraction spring of a lateral-traction roller shade is fastened to an interior rod that is stationary once it has been installed. The other end of the spring is fastened to a carrier bushing that rotates on the interior rod. The shaft of the shade is attached to the bushing and one end of a retention and clamping spring that surrounds the rod is fastened inside the bushing in such a way that the spring will rotate along with it. The other end of the spring is positioned in the path traveled by a drive segment on a sheave when the shade is lowered and in front of a drive rib on the bushing that is also positioned in the path. The raising of the shade is thus facilitated by the retraction spring.

Abstract: A procedure the life of wood-cutting tools and relates to the cutting of green wood and comparable organic materials. The dulling of tools in such cutting is mainly corrosion of the cutting edge of the tool, which could be almost completely prevented under laboratory conditions by applying a high-voltage direct current. The dulling is also limited in practice in the procedure, which is based on the realization of the specific resistance of wood which is sufficient to render unnecessary the electric insulation of the tool or the wood being cut from the frame of the cutting machine. Such an operation is difficult to carry out, but was formerly believed to be indispensable. The invention, the negative terminal of a DC source is connected with the grounded frame of the machine. The current is conducted from the positive terminal of the DC source, using a suitable anode brush, into green wood acting like an electrolyte at a point close to the tool that is to be protected. The wood-cutting tool, and on its side also the means for feeding and supporting the wood, will then act as cathodes in the system and they will be protected against wear caused by corrosion.

Abstract: A single microcomputer controls the firing time determination for two independent current regulators for two six pulse AC/DC converters which are part of a twelve pulse parallel controlled current inverter (CCI) AC motor drive. A very short high priority interrupt occurs when a motor channel source converter thyristor fires. This interrupt calls a longer, low priority current regulator interrupt informing it that a master channel source converter thyristor has just been fired. The current regulator causes a count to be loaded into a master fire counter and also loads a firing mask into a hardware latch or buffer. When the master fire counter times out the next thyristor pair of the master channel source converter is fired directly out of hardware. Similarly, there is a separate slave channel fire counter loaded after the current regulator is called by a short high priority interrupt when a thyristor in the slave channel source converter fires.

Abstract: An air-pressure impact type drilling method and an apparatus for the same in which a piston of an air hammer drill is moved up and down by pressure air to produce impact energy and the impact energy of the piston is used to give impact vibrations repetitively to a drill bit. In the air-pressure impact type drilling method and the apparatus for the same, the air hammer drill is operated by the pressure air to be supplied from the ground, the air that has already been used for operation of the air hammer drill is exhausted onto the ground through an air exhaust pipe provided in a drilling pipe and communicating with an air exhaust passage formed in the air hammer drill, and substances cut out by the air hammer drill together with muddy water within the trench are discharged by means of a reverse circulation system while drilling on through the earth. As a result of this, even if the water head pressure acts on the tip end of the drill bit, the pressure of the air for operation of the piston will not be affected by such water head pressure and thus the drilling performance of the air hammer drill will not be ill affected even under the muddy water.
