Abstract: A suction for the combustion air of a heater, in particular a motor vehicle heater, has a variable cross-section of flow. The object of the invention is to improve the operation of the device that modifies the cross-section of flow and to allow it to be more rationally produced. In addition, it should allow the suction air to be filtered in association with said means without extending the axial length of the heater. For that purpose, the suction pipe is designed as an axially closed tube with radial openings whose cross-sections may be changed by a coaxial, rotary ring set on the outside of the pipe and provided with radial openings. A hood may be axially drawn over the ring on the housing of the heater. Suction air may be filtered in said hood, either by centrifugaton in spiral channels arranged in the hood or by using a ring-shaped filter through which the suction air flows in the radial direction.
Abstract: Buckle folding machine including folding pockets, which have a paper stop each. One folding pocket being for collection and subsequent joint folding of a plurality of sheets. From the folding pocket the collected sheets of paper pass together through a folding mechanism, having a draw-in point formed by upper and lower draw-in rollers and having at least one pair of folding rollers forming a folding point. A sheet feeder with a conveyor track directed toward the draw-in point, in which a stacking ramp is located, is arranged in front of the draw-in point.
Abstract: The buckle (1) comprises a compartment (11) that cannot be seen from the outside, for holding small objects, the compartment being easily accessible to the user who is wearing the buckle.

Abstract: A device for the protection of cables laid in switch cabinets, other equipment or the like, in order to prevent bends below a minimum bending radius at the exits of cable ducts or similar equipment and that prevents corresponding damages. At the exit openings of cable ducts guiding devices are provided and configured such that they prevent falling below the critical bending radius and that they widen in the direction of exit and are rounded.
Abstract: A collar flexibly movable between a first shape defining an opening for receiving one end of a cup and a second shape where the collar is substantially flat. A handle is flexibly connected to the collar. Tension members attach to the handle and collar on opposite sides of the handle to provide two opposing forces which prevent the handle from moving with respect to the collar.
Abstract: An attic opening cover and a process for forming the cover are provided. The cover includes a first composite end element including a protective layer bonded to a thermally insulating layer. A second composite end element is provided including a protective layer and a thermal insulating layer. A first composite side element is provided including a protective layer bonded to a thermal insulating layer. A second composite side element is provided including a protective layer bonded to a thermal insulating layer. A composite top element is provided including a protective layer bonded to a thermal insulating layer. A fastening arrangement is provided including fasteners extending through the first composite end element, fasteners extending through the second composite end element, fasteners extending through the first composite side element, fasteners extending through the second composite side element and fasteners extending through the composite top element.
Abstract: A releasing device for rocket fuel lines, arranged between a tank outlet and a shutoff valve, which releases the flow path at a defined, tank-side overpressure, with a piston-like bursting element. A disk is provided with a predetermined breaking point and with a clamping flange, as well as a guide rod that is rigidly attached to the disk, and a catching basket that is permeable to flow and fixes the disk in a positive-locking manner after rupture and axial movement.
Abstract: The part (1) to be machined, which exhibits an axis of revolution (aa') is secured in a rotatable spindle (11) forming part of a headstock (10) movable in translation on the framework of the grinding machine according to a longitudinal axis (X) parallel to the axis of revolution (aa'). A support (16) fixed to the framework and in the immediate proximity of which is arranged a grindstone (18), serves as lateral support to a portion of the part (1) to be machined. Grinding of the part (1) by the grindstone (18) over an arbitrary length capable of exceeding 1000 times its diameter, is effected by displacing the headstock (10) by such length in the sense of the longitudinal axis (X).
Abstract: A device for calibrating a gas meter, in which gas to be analyzed is introduced into a measuring chamber by a delivery device via a delivery line. A storage tank is provided containing a calibrating substance, which tank is connected to the measuring chamber via a feed line. The storage tank is designed as a tank through which the gas to be analyzed can flow and has a gas inlet. A flow divider is provided in the course of the delivery line. A partial flow of the gas to be analyzed is sent by the flow divider to the gas inlet via a section of the feed line. The gas meter is an electrochemical measuring cell determining a measured concentration value of the calibrating substance in the gas to be analyzed in the measuring chamber. An infrared meter is provided, which evaluates the gas to be analyzed in the measuring chamber and generates a reference measured concentration value for the measured concentration value determined with the electrochemical measuring cell.
Abstract: A triaxially stabilized earth oriented satellite is provided with an attitude control system. The attitude control system contains a controller, final control elements for generating control torques around each of three axes of a system of coordinates (principle axes x, y, z) fixed relative to the satellite. Additionally, the attitude control system comprises, as measuring transducers, exclusively a direction vector measurement device, like a magnetometer or star sensor, a sun sensor array and an earth sensor. The process of the invention makes use of the apparatus as noted above and includes the steps of:A. determining an estimate for the rotating velocity of the satellite from a direction vector measurement;B. searching for the sun, depending on the size of the field of view of the sensor, by one or two search rotations at right angles to the optical axis;C. adjusting the direction of the sun relative to the optical axis; andD. adjusting the direction vector measurement to a reference direction S.sub.

Abstract: To embroider combination patterns composed of partial patterns on sewing or embroidering machines with a driven embroidery frame, a common sewing stitch each, which is used as a hooking point, is located outside the contour of the pattern, and whose connection threads to the pattern proper are removed after finishing the second partial pattern, is formed at the end of the first partial pattern and at the beginning of the second partial pattern for the exact positioning of the partial patterns.
Abstract: A process and system for the computer-aided geometry modeling which makes possible a declarative, sequence-independent description of geometric shapes and geometric features and leads to an integrated modeling, which unites in itself geometric relationships and connects them with non-geometric information. To achieve this, the geometry-related information is represented in the form of a representation element, to which a density (.rho.) is assigned in the form of a real number. The linking of individual representation elements is performed by a single commutative and associative linking operation. A volume level, a topology level, and a generic area and edge level located between these levels are provided as the description levels for the actually relevant information. A feature level, at which features are defined and at which a knowledge-based system can be used, is located above these description levels.
Abstract: A vehicle heater with a burner, a fan for the combustion air to be fed to the burner, a heat exchanger for heating the engines's cooling water, which is circulated in a closed circuit, and with a control device. A basic housing is provided substantially in the form of one of a parallelepiped and a semicylinder with an essentially flat, continuous upper housing surface. The basic housing is axially divided into a first housing end section, which is located at a first end and accommodates the burner and the heat exchanger, a middle housing part containing the fan, as well as a second housing end section comprising the control device. The inlet and outlet connections of the heat exchanger as well as a connecting branch for fuel to be fed to the burner are located within the upper surface of the basic housing.
