Abstract: (12223A) (28.1.80) ABSTRACT    A wooden board for use for example as a table top has a moisture-proof coating on its upper surface and an edging of synthetic material which is sprayed under pressure on to the cut edge surface of the board.          The edging overlaps the adjacent edge of the upper surface of the board and penetrates a profiled cut-out in the edge surface.  In order to give a good moisture seal, the cut-out profile has an inwards directed back cut immediately under the upper board surface and a lower outwardly directed projection.

Title: System for controlling the change of read side  for an optical reader for an information carrier  and an optical reader including such system
Inventor: OPRANDI PIERRE

Filed: 1980-05-29
Granted: 1983-03-15
Abstract: ABSTRACT OF THE DISCLOSURE System for changing the read side on a transparent carrier carrying information recorded on both sides. Reading is carried out by means of an optical device focusing a light beam onto one preselected side, incorporating a feedback loop servomechanism which maintains constant the distance between the optical device and the recorded surface of the disk. The servomechanism is attached or connected by the detection of the high frequency electrical signal representing the recorded information. The system opens the feedback loop when, after the read side change control, the high frequency signal drops below a predetermined threshold. A side jump control pulse imparting an accelerated movement towards the other side to the focusing device is generated synchronously with said loop opening. The high frequency signal again rises above the predeter-mined threshold when the light beam focusing point reaches the opposite side. At this time, the loop is closed again and a decelerating pulse is generated.

Fire tubes carrying water or steam are positioned to receive heat from the burning gases.  At the outlet of the reducing section precooled stack gases are injected into the flame so as to cool the hot products of combustion.  The direction of flow of hot gases is turned 90° in a second section.  At the end of the second section the direction of flow is turned 90° so as to be counter to the first direction in a third or oxidizing section to which secondary air is added and a fourth or boiler section accepts the hot gases from the oxidizing section to recover the waste heat.

Abstract: ABSTRACT OF THE DISCLOSURE:            During the continuous casting process, metal melt flows from a reservoir covered with a slag layer into a tundish covered with a slag layer, and from there into a mould. In order to prevent a damage to the strand or the continuous casting plant on account of the slag entry into the mould and the jeopardization of the operating personnel, the height of the metal-melt-bath level on the one hand and the height of the slag-bath level on the other hand are continuously determined.          From the relation of these values the slag amount present in the tundish is determined.

Abstract: ABSTRACT OF THE DISCLOSURE Normally solid dissolved coal product and a distil-late liquid product are produced by continuously passing a feed slurry comprising raw feed coal and a recycle solvent oil and/ or slurry together with hydrogen to a preheating-reaction zone, the hydrogen pressure therein being at least 1500 psig (105 kg/cm2), reacting the slurry therein at a temperature between about 455° and about 500°C to dissolve the coal to form normally liquid coal and normally solid dissolved coal. A total slurry residence time is maintained in the reaction zone ranging from a finite value from about 0 to about 0.2 hour, and reaction effluent is continuously and directly contacted with a quenching fluid to substantially immediately reduce the temperature of the reaction effluent to below 425°C and inhibit polymerization so that the yield of insoluble organic matter comprises less than 9 weight percent of said feed coal on a moisture-free basis.  The reaction is performed under conditions of temperature, hydrogen pressure and residence time such that the quantity of distillate liquid boiling within the range C5 - 455°C is an amount at least equal to that obtainable by performing the process under the same conditions except for a longer total slurry residence time, e.g., 0.3 hour.  Solvent boiling range liquid is separated from the reaction effluent and recycled as process solvent.  The amount of solvent boiling range liquid is sufficient to provide at least 80 weight percent of that required to maintain  the process in overall solvent balance. The present process involves the remarkable discovery that a greater liquid yield can be produced at a short residence time under controlled conditions, than at a longer residence time under otherwise similar conditions, even while the primary product fraction is normally solid dissolved coal and the production of net liquid product is not encouraged.
