Abstract: A gas burner for a cooking device. The gas burner includes a burner head connected to a mixing pipe. An impeller disk is disposed above the burner head and below a cover. The impeller disk is operable to swirl a gas stream and defines a generally circular inner opening. The impeller disk includes a body and a plurality of paddle-shaped flame guidance members formed by a plurality of evenly-spaced and radially-directed cuts in the body. The flame guidance members are bent such that edges of the flame guidance members form oblique angles with the body. The edges each have an end disposed above the body and another end disposed below the body.

Abstract: A cooking assembly has a main burner, a pilot burner mounted in it and having a vent, a gas valve having separate main and pilot gas outlets, and a main-burner controller including a temperature sensor on the main burner, a control unit on the valve capable of varying gas output from the main gas outlet, and a capillary tube connected between the sensor and the control unit. This controller can vary gas flow from the main outlet in accordance with the temperature of the main burner as sensed by the sensor. An electrical igniter on the main burner can be energized by a switch on the valve. A pilot-burner controller connected to the switch includes a thermoelectric sensor in the pilot vent and blocks gas output from the gas outlets when insufficient heat is detected by its sensor and the switch is not closed.

Abstract: A cooking range in which a burner below a glass-ceramic plate is ignited with a glow igniter switched off in response to an ionization detector when combustion products are effected so as to prevent excessive heating of the glow igniter.

Abstract: An accessory unit (2) for a sewing machine (1) for automatically sewing pieces of ribbon material (20) onto a sewing material (5), has a hollow guide shaft (23) with a longitudinal slot (24) to guide the ribbon material (20). A needle (25) is used as an advance feed mechanism and can be inserted through the slot (24) into the ribbon material (20) which passes through the guide shaft (23), by means of which the ribbon material (20) can be advanced in the longitudinal direction of the guide shaft (23). The accessory unit (2) can be swivelled around a vertical axis (x) by at least 90.degree. relative to the sewing machine (1).

Abstract: A cooking unit has a ceramic cooking surface, a gas burner underneath the surface, a gas supply including a solenoid valve for feeding a combustible gas to the burner, and an electric igniter juxtaposed with the burner and electrically energizable to ignite the combustible gas issuing from the burner. An electricity supply is connected to the igniter and to the gas supply for electrically energizing the igniter whenever the valve is open and supplying gas to the burner. In addition an electronic controller connected to the valve and to the electric supply monitors current consumption of the igniter and closes the valve when the current consumption of the igniter indicates same is malfunctioning. The controller includes a digital circuit that is also typically operated by the user of the cooker to turn the burners on and off and control their temperatures and an analog circuit connected parallel to each other. At least one of these circuits controls opening and closing of the valve.

Abstract: A cooking unit has a housing having a front and a rear and formed at the rear with an upwardly open upright vent passage, a ceramic panel on the housing defining a plurality of cooking spots, a burner plate in the housing spaced underneath the panel and defining therewith an upper compartment opening upward into the passage, and respective gas burners supported on the plate underneath the spots. Thus the burners can heat the respective spots of the panel. An equipment plate in the housing spaced underneath the burner plate defines therewith an intermediate compartment also opening upward into the passage and defines beneath itself in the housing a lower compartment that is open to the outside at the front of the housing. Control equipment is mounted in the lower compartment of the housing along with a blower having an intake in this lower compartment and an outlet in the vent passage.

Abstract: The invention is concerned with a cooking range, especially suitable for mobile homes, which utilizes gas burners, where the exhaust gas draft is held substantially constant and the exhaust duct temperature is kept below a critical temperature by providing temperature-regulated cool air openings on the exhaust gas duct. Reliable regulation is accomplished by closures controlled by bimetallic springs positioned in a swivelable manner in the cool air openings so as to act on the closure flaps, and the closure action further improved by restoring springs exerting pressure on the outside of the closures.

Abstract: Gas range with at least one burner covered by a glass ceramic plate, wherein the burner has a gas cock and a timed-ignition and monitoring device, such that the output of the burners is adjustable. A gas cock is used with plugs rotatable between a high and a low position with the aid of a knob and a knob shaft, with a spindle connected to the knob shaft, with a valve plate under the gas inlet opening in the plug housing, with a microswitch for the ignition device and with the use of an electromagnet under the valve plate, in the area of the gas supply connection of the further housing. The knob with the knob handle and the spindle is pressable against the action of a return spring in the high position of the plug. This way, the microswitch for the timed ignition device becomes actuatable and the valve plate becomes pressable on the electromagnet against the action of a return spring, thereby opening the combustion gas inlet opening.

Abstract: A method of automatically producing seams in fabric webs, especially sackings or ticks of (wadded) bed quilts, by producing the seams during, and with the aid of, a freely programmably relative movement between the fabric web and at least one sewing machine head. The fabric web is drawn continuously or successively (in steps) and against a constant take-up force along a linear path, and the sewing head performs program-controlled motions in a processed web portion extending transversely of said path. A system for carrying out this method, utilizes a machine table and an associated quilting-sewing machine having an arm and a machine head mounted to the latter. The arm (20) is guided by a pair of supports (6, 7) positioned perpendicular with each other and adapted to be moved in the longitudinal direction (X) and transverse direction (Y) by freely programmably controlled drive apparatus.

Abstract: In a grill basket, two mutually adjustable wire basket halves are provided. These wire basket halves comprise two longitudinal rods, the ends of which are bent-over in a hook-like manner. The two longitudinal rods are connected by transverse wires which are spaced at intervals from one another. End plates are provided for the adjustable connection of the two wire basket halves, and parallel, spaced-apart rows of holes are formed in each plate. The wire basket halves are hookable into said plates by their bent-over ends on the longitudinal rods, in the same way as perforate hooks are hooked into perforate walls. The spindles are disposed on their respective plates so that the grill basket is rotatably mounted on the appropriate means of a grill.

Abstract: For the marking of gas-permeable fabric or cloth webs and other material webs, especially for the automatic marking in a marking station, the invention proposes to contact the fabric web within the marking station with a film including the pattern to be marked off in the form of perforations and acting as a stencil, and to suck atomized paint (paint mist) through the perforations and the contacting fabric web, wherein this atomized paint is an aerosol produced by atomization of a liquid containing a dye or pigment dissolved therein. Advantageously, a fluorescent dye is used to this end.
