Title: Process for cleaning the fire tube of a boiler provided with at least one fire tube, and device for carrying out the process
Inventor: ADRIAN FRITZ DIPL ING
IPC: F28G3/16
Filed: 1981-02-20
Abstract: The fire tubes of flue boilers or combined flue and smoke-tube boilers have to be cleaned more often, when using high-ash fuels, in order to prevent the heat transfer being reduced too greatly by ash deposits and to overcome the danger of sinter-fusing or the formation of lumps. In order to be able to clean the wall of the fire tube (3) in a simple manner, the invention proposes that parts of the wall of the fire tube be blasted successively with a blasting medium, the blasting direction and the flue-gas flow enclosing an angle < 90 DEG . In the case of a preferred cleaning device for carrying out the cleaning, the invention provides a long-tube blasting means (12) with a blasting tube which can be retracted into and extended out of one end of the fire tube (3) and on the front end of which there is arranged a blasting nozzle head (13), whose blasting-jet direction, preferably defined by blasting nozzles (14), and the flue-gas flow (8) enclose an angle < 90 DEG . The long-tube blasting means is preferably a long-tube helical blasting means, the blasting-nozzle head of which is provided with at least two blasting nozzles which are offset with respect to one another in the circumferential direction. At that end of the fire tube which is not occupied by the long-tube blasting means, at least one fuel burner (4) can be arranged, or a pre-firing means can be connected upstream thereof. <IMAGE>

Title: Nozzle of a fuel injection valve for a diesel engine
Inventor: FUCHS PETER
IPC: F02M61/18
Filed: 1981-04-09
Abstract: Downstream of a valve seat (20) the nozzle body (6) has, in at least one plane lying transversely to the valve axis (2), a plurality of nozzle ducts (1) opening into the combustion chamber of a cylinder. Each nozzle duct (1) has an inlet section (5) and an outlet section (4) through which the fuel flows in succession. The outlet section (4) has a shallow rectangular cross section increasing continuously towards its outlet. The boundary surfaces (13) of the inlet section (5), which run from the inlet towards the two longer sides of the rectangle of the outlet section (4), are curved so that the flow components, directed parallel to the short sides of the rectangle of the outlet section, of the fuel flowing in the inlet section essentially cancel one another out before entering the outlet section. This permits improved utilisation of the combustion space and thereby more efficient combustion of the fuel than in nozzles with ducts in the form of Laval nozzles. <IMAGE>

Title: Device for providing potted plants with liquid
Inventor: KIRCH ERWIN
IPC: A01G27/04
Filed: 1982-01-14
Abstract: The invention relates to a device which allows potted plants in culture pots of any shape and size to be provided with water and/or liquid nourishment. This takes place in conjunction with any type of container, for example with ornamental pots whose size and shape are irrelevant. The water supply for the plants is generally displayed by means of a water level indicator so that lacking water can be topped up. The water level is indicated visually. The invention sets out from the object of providing a device for providing potted plants with liquid in conjunction with a container, a wick and a water level indicator. This device is to allow any culture pots to be combined with any containers, specifically for the normal case with controllable water level and for long-term provision of liquid to the plants. The device has one or more attachment elements (100) with a polygonal contour which is preferably octagonal or hexagonal. Due to the overlappings (108) and overlapping surfaces (109), these attachment elements can optionally be fitted one above the other or in a flat arrangement adjacent to one another due to the projections (107) and grooves (106). Additionally, these attachment elements have a flat attachment surface (110), as well as an outer ring (105) and an inner ring (104), which rings are connected to one another by webs. The overlappings, which are mounted on the outsides of the outer ring, are situated below the overlapping surfaces, the outer dimensions of the projections corresponding to the inner dimensions of the grooves. The water level indicator (800) is a hollow guide element (801) with a laid-out insertion part (802) at the lower end. The insertion part corresponds in its dimensions to the grooves of the attachment element. The float (803) is attached to the indicator flap (804). At its upper end, the guide element has markings whose vertical intervals correspond to the height of an attachment element.   <IMAGE>

Title: Circuit arrangement for analog-digital and digital-analog conversion of speech signals in telephone stations
Inventor: LEISTNER RUDOLF
IPC: H04M1/65
Filed: 1982-01-15
Abstract: The invention relates to a circuit arrangement for analog-digital conversion or digital-analog conversion of speech signals in telephone stations where, for example, for a built-in digital answering machine, incoming analog signals must be converted into digital signals and outgoing digital signals must be converted into analog signals. For this purpose, a conversion device (US (RL, a1, a2)) is required, which converts incoming analog signals (E2) into digital signals and feeds them via a bandpass filter (BPF) to the answering machine (via A1, Aa), or converts digital signals (E1) output by the answering machine (Ae) via a bandpass filter (BPF) into analog signals (and outputs them via A2). The object of the invention is to economise on band groups - in this case a bandpass filter - through appropriate controlled circuitry. This is achieved by disposing three electronic switches (ES1, ES2, ES3) according to the figure and controlling them by means of a transmission direction identifier (ÜE) in such a way that only one bandpass filter is required overall for both transmission directions, which filter is always looped into the correct direction by appropriate setting of the switches. <IMAGE>

Title: Electric steam iron
IPC: D06F75/18
Filed: 1982-02-15
Abstract: In an electric steam iron with a stand having a handle, with a water storage tank supported by the stand and with an iron foot held on the stand, this iron foot consists essentially of a sole plate and of a cover plate. At the same time, the sole plate has a heating device, encased with a U-shaped heating channel and controlled by a thermostat, and an evaporator chamber arranged between them at their vertex point, as well as steam-guide channels guiding the steam to a plurality of outlet ports located on the underside. The cover plate engaging over the sole plate also has parts of the evaporator chamber and steam-guide channels which guide the steam and which are formed by ribs which, on the one hand, extend rearwards coincidentally with the walls of the evaporator chamber and which, on the other hand, lengthen the inner and outer casing walls of the heating channel in regions flush at the top, and slide the steam along the heating channels. To prevent the heating device from being cut off via the thermostat precisely when even larger quantities of steam are to be formed as a result of the inlet of larger quantities of water into the evaporator chamber, the evaporator chamber is formed in the water drip-in region by a rib wall, arranged at a distance from the inner casing wall of the heating channel, both in the sole plate and in the cover plate, the rib wall maintaining its distance from the heating channel as far as the connection point of the thermostat, and this connection point being surrounded in regions by the rear part of the evaporator chamber.

Title: Device for producing printing plates
Inventor: KOCHSIEK ADOLF
IPC: G03F9/00
Filed: 1982-02-19
Abstract: The intention is to improve the positioning of the film and printing plate to improve the register accuracy, in particular for multicolour printing, on a device for producing printing plates, in particular negative offset newspaper printing plates, which device has two exposure stations, a system for the positioning and fixing of the film and printing plates by positioning pins and negative pressure and an apparatus for transporting the printing plates between the exposure stations. In this case, printing plates of different formats are to be produced continuously in a simple manner from a printing plate roll and it is to be possible for the printing plates to be exposed on a device having at least two exposure stations, i.e. with multiple exposure, so that a considerable increase in the number of printing plates produced per hour can be achieved by the improved film positioning and thus quality. For this purpose, there are arranged successively in the direction of transport an apparatus for the fastening and unwinding of a printing plate roll, an aligning station, a printing plate coating apparatus, a cutting station operating by suspension, and exposure stations. Each exposure station has a pivoting frame, provided with at least two positioning pins arranged spaced apart, for fastening the film. The pivoting frame is arranged in the loading position obliquely at an angle of inclination to the vertical plane. It has an apparatus for suction fixing and is pivotable from the oblique position into a horizontal position with the film arranged downwards. It can be lowered onto the printing plate which is arranged below it and can be moved in cycles on a linear transfer apparatus, a lamp arranged above the pivoting frame being provided for the exposure.

Patent DE-3213401-A1 (DE)
Title: Novel supporting table with split-material bearing strip as complete accident protection in firewood splitters
Inventor: OTT HERMANN
IPC: B27L7/04
Filed: 1982-04-10
Abstract: The invention relates to a device which through redesign of the supporting table brings about a complete transformation of the firewood splitter. This is achieved through the allocation of the split-material bearing strip, which makes it impossible for the split material to turn over. At the same time, any length can thereby be split by raising and lowering the supporting table. Since it can be pressed down, jammed split material is easy to remove, and, since there are hinges at the rear side, the hand and twist-wedge guard (P 3105260.6) can be attached. The supporting table must be attached horizontally. Through allocation of the side stabilising support, which immediately splits any type of wood due to its hard resistance and is adjustable, firewood can be split from kindling to thick wood. The belt guard is not present on account of the accident risk. For this, a double iron belt guide is attached to the frame of the circular saw. Due to the above-mentioned innovations, the splitter is very simple to operate and is completely accident-free. It is especially advantageous in the firewood splitter to place the switch lever of the motor or the power take-off shaft near the operator by means of an extension bar or cable.
