  • Patent number: 4958817
    Abstract: An operating table comprises a patient rest or support structure which is mounted at a rolling bearing, i.e. a bearing associated with the rolling motion of the patient rest or support structure. The axis of this rolling bearing corresponds with a rolling or roll axis and defines a predetermined angle with the patient rest or support structure, so that the extension of the axis of the rolling bearing, subsequent to intersection thereof with the plane of the patient rest or support structure at a predetermined punctiform location, extends substantially through the center of an operating site defined in or at the head of a patient stretched out on the patient rest or support structure. In this manner, it is rendered possible that, when rolling movements or motions with the patient rest or support structure are accomplished by means of a suitable drive for such rolling motion, the center of the operating site remains essentially unchanged at the same location.

  • Patent number: 4421476
    Abstract: In a gasification burner comprising an antechamber for mixing fuel and primary air; a catalytic device for generating a fuel gas from the fuel/primary air mixture; a mixing chamber for mixing the fuel gas with secondary air; an annular space which surrounds the antechamber, the catalytic device and the mixing chamber being separated from the antechamber by a ring wall provided with radial canals; a combustion chamber and a burner plate terminating the combustion chamber; and an ignition chamber arranged between the combustion chamber and the mixing chamber the operating safety is increased by having the annular space also enclose the ignition chamber and the combustion chamber in ring-fashion and extend up to the vicinity of the burner plate; a primary air feed stub opening into the annular space; and baffles in the annular space which baffles conduct the primary air stream from the primary air feed stub to the radial canals of the ring wall in spiral or meander fashion about the combustion chamber and the ig

  • Patent number: 4406611
    Abstract: The invention relates to a method for operating a gasification (or vaporizing) burner/heating boiler installation and has the objective to develop such an installation in such a manner that it can be operated controllably. According to the invention, the required burner output is determined for this purpose from the outside air temperature, and then the mass flows of the heating oil and the air are controlled as a function of the demanded burner output, deviations from the stoichiometric ratio between the heating oil and the air being leveled-out by means of a lambda-probe arranged in the exhaust gas stream.

  • Patent number: 4230443
    Abstract: A vaporizing burner which includes a multi-portioned burner housing. The housing encompasses an inlet chamber, ahead of which there is located an antechamber which transitions into an annular passageway wherein heating oil is vaporized. The heating oil is admixed with preheated primary air and converted into a fuel gas in a catalyzer arrangement. Thereafter, the fuel gas is admixed with secondary air in a mixing chamber, ignited in an ignition chamber and conveyed into a further chamber. The last-mentioned chamber is closed off by a burner plate which is heated by the fuel gas and which transmits the usable heat to a suitable heat exchanger.

  • Patent number: 4131569
    Abstract: An oxidic catalyst for the conversion of water gas which consists of oxides of the metals aluminum, lanthanum, cobalt, nickel and uranium, with the aluminum oxide being present predominantly as .alpha.-Al.sub.2 O.sub.3. The lanthanum and cobalt content is 5 to 30% by weight, that of nickel, 0.1 to 4% by weight and of uranium, 0.1 to 2% by weight, related to the total weight of the catalyst.
