Abstract: The invention relates to an apparatus and method for tracking energy consumption. An energy tracking system comprises at least one switching element, at least one inductor and a control block to keep the output voltage at a pre-selected level. The switching elements are configured to apply the source of energy to the inductors. The control block compares the output voltage of the energy tracking system to a reference value and controls the switching of the switched elements in order to transfer energy for the primary voltage into a secondary voltage at the output of the energy tracking system. The electronic device further comprises an ON-time and OFF-time generator and an accumulator wherein the control block is coupled to receive a signal from the ON-time and OFF-time generator and generates switching signals for the at least one switching element in the form of ON-time pulses with a constant width ON-time.

Abstract: To reduce the risk of damage to the refractory material, in particular caused by the formation of cracks and corrosion, the invention provides a unit, in particular a melting and/or refining unit and/or a distributor system and/or a channel system, for conductively heatable melts (30), in particular glass melts, which has a tank and at least one electrode (20), the electrode (20) passing through an opening in a wall (10) of the tank so as to be immersed in the conductively heatable melt (30), wherein the unit has an apparatus for reducing the local introduction of heating power into at least one region—adjacent to the electrode (20)—of the wall (10).

Abstract: The invention relates to a method for suppressing the formation of oxygen gas bubbles at the contact interface between a glass melt and a component of a glass melting arrangement with this component being made of a precious metal. This component is especially the precious metal lining of a feed channel. The characterization “precious metal” includes in this context: platinum, gold, rhenium, all other metals of the platinum group, the alloys of the above-mentioned metals and the above-mentioned metals and alloys in dispersion oxide enhanced form. The occurrence of gas bubbles at the phase boundary between precious metal and the glass melt has been known for some time without effective measures having been suggested up until now to improve significantly the quality and yield of the generated glass products, particularly because precious metal parts have to be arranged in the glass manufacture downstream of the usual purification devices with which gas bubbles can be removed from the melt.

Abstract: A saw chain formed in part from planar cutting link blanks including a cutter portion having a top edge surface and a side surface that intersect to form a line edge. A leading portion of the cutting link blank is twisted out of the plane of the blank so that the line edge becomes the cutting edge of the cutter and extends from the plane of the body to encompass the width of one side of the saw chain. Alternating cutting link are formed to have oppositely extended cutting edges to encompass the width of the saw chain. The cutting links preferably form certain of the center links of an assembled saw chain.

Abstract: A high speed harvester cutting chain has increased cutter height to provide an increased space for removal of the cut material from the saw kerf. The increased height of the cutter links eliminates the compacting of the material cut away by the cutter links between the saw chain and the base of the saw kerf. The foot of the cutter links are flared outward to contact the guide bar rails at a different position than the tie straps to increase the wear life of the guide bar and saw chain.

Abstract: A chain tensioner for a chain saw has a cam member in positive engagement with a flange of a plate attached to the guide bar. Rotation of the cam member forces the guide bar away from a drive sprocket of the chain saw to tension the chain. The cam member is clamped in position to maintain the guide bar in the adjusted position. Flats on the cam member in abutment with the flange resist rotation of the cam member when in the adjusted and clamped position. A slot is provided in the cam member to facilitate rotating the cam to force the guide bar away from the drive sprocket.

Abstract: A holding element serves for the vertical fixation of a pane of glass to be glued in the frame of a motor vehicle. It consists of a holding part made of a hard elastic plastic inserted in a lower cross frame and a number of elastically insertable supporting steps connected to it with supporting faces arranged at equal distances one above the other to support the lower edge of the pane. In order to achieve the finest possible gradation of the individual supporting steps and simultaneously a no-play mounting, the supporting steps are designed to engage one another in a lamellar manner and are connected in each case to the holding part on both sides of the support area via elastically flexible cross members on their lamellar ends.

Abstract: Method and apparatus for manually applying a selected fit of a saw chain loop to a chain saw. A tensioning procedure is performed simply by loosening a guide bar hold-down screw. The loosened guide bar is slightly spaced away from the mounting plate of the chain saw as a spring extends the guide bar relative to a drive sprocket which tightens the saw chain. The hold-down screw, which has an inclined axis, is then tightened to force the saw bar obliquely toward the mounting plate, simultaneously forcing the guide bar in a longitudinal direction that backs off the saw chain tension by a predetermined amount.

Abstract: A cutting saw chain for aggregate materials including a loop of articulated chain links adapted to fit the guide bar of a chain saw. The guide bar is provided with a flushing system whereby pressurized water is directed through the bar and into the path of the guided saw chain to cool the chain and flush away debris formed in the cutting operation. The cutting link structure is a folded plate-like member formed into spaced side plate portions and an overhead connecting web. The side plate portions function like side links in a conventional saw chain and ride on the rails of the guide bar. Rivet holes are formed in the side plate portions. Rivets projected through the rivet holes connect the side plate portions to front and rear center links. The side plate portions are fixed in spaced relation by the connecting web an permits the use of rivets with straight shank. The connecting web supports front and rear sections of a cutting block.

Abstract: A lightweight disposable cutting chain for use with small, compact power supplies comprises in one embodiment a series of links formed of wire. On certain links an end of the wire loop forming the link is cut to form a sharp edge capable of shaving material, such as wood, being cut. The links are arranged so that a narrow kerf is first cut by the links, other links being formed with cutting edges to shave material and widen the kerf. In other embodiments some or all of the links comprise metal plates formed by stamping from sheet metal.

Abstract: A piecing process is provided for an open-end friction spinning apparatus of the type including movable friction surface members forming a yarn-forming zone therebetween. A friction surface driving device for moving the friction surface members during operation and for interrupting the movement of the friction surface members is also included in the apparatus. The spinning apparatus further includes a yarn end orientation member for orienting a yarn end during the piecing process. The process includes placing a yarn end into the yarn-forming zone when the rollers are stopped. The friction surface members are started such that the yarn end is prevented from being pulled too deeply into the yarn-forming zone by the yarn end orientation device. An apparatus for carrying out this process is also provided.
