Title: Solid-fuel burner for industrial furnaces having a flame-space muffle
Inventor: HARTMANN HEINZ-LEOPOLD DIPL IN
IPC: F23M9/06
Filed: 1981-02-05
Abstract: The invention relates to a solid-fuel burner for industrial furnaces having a flame-space muffle. It is intended to improve the muffle overheating which, in the combustion of solid fuels, is necessary in order to improve the burn-out (flame formation, flame colour), whilst lost times for muffle preheating and the dependence of the latter on the ignition flame or on a separate preheating flame are to be avoided. It achieves this in that the flame-space muffle is equipped with an electrical resistance heater cast around the muffle body on the outside.
Patent DE-3105679-A1 (DE)
Title: Double-acting electric motors
Inventor: POISEL OTTO KARL DIPL ING
IPC: H02K7/116
Filed: 1981-02-17
Abstract: The invention of double-acting electric motors (electric motors which act on two sides) is based on the principle of a linear drive having a rotating annular rotor (1) which may comprise one or two parts and, in consequence, an identical or opposite rotation direction of the output drive shafts (4) is ensured. Depending on how large the output drive rotation speed range is intended to be, suitable gears (2) can be integrated. The annular rotors (1) guarantee that the two output drive shafts (4) are driven at absolutely synchronous output drive rotation speeds without the slightest mutual angular displacement within a revolution. The rated power depends on the number of inductor double-comb segments (3) installed. The rotation speeds can be continuously regulated using a thyristor controller. Because of these properties, double-acting electric motors are intended for the following areas of use: in machine constructon, they are used as drive units for two synchronously running machines, in conveyor technology they ensure synchronous running of two conveyor belts, and in aviation and space technology as well as defence, they are the building block of all "novel drive systems". <IMAGE>
Patent DE-3109215-A1 (DE)
Title: Notepad or similar paper product serving as an information medium, and method for its production
IPC: B42D15/00
Filed: 1981-03-06
Abstract: A novel notepad or similar paper product serving as an information medium is described. It is notable for a large number of possible applications and, at the same time, the possibility of multiple use. The notepad is characterised by various imprints on both sides of each individual sheet. As a result of their special combination between an activatable pressure layer of adhesive and contact pressure adhesive, they render superfluous the conventional stitching together of the individual sheets to form a pad or spinal gluing along an end surface. The detachable adhesive effect between the individual sheets of the pad is achieved in connection with the production thereof, preferably during the cutting of the edges. The activatable adhesives in the various imprints are activated by the cutting process and the associated pressure, and the adhesive join is thus produced. When the individual sheets are detached from the pad, this adhesive join ensures that the surfaces of the individual sheets are not damaged and the free writability of each individual sheet is not impaired.
Patent DE-3109288-A1 (DE)
Title: Bar-code readable with an optical reader and optical reader therefor
Inventor: APITZ SIEGFRIED
IPC: G06K7/10
Filed: 1981-03-11
Abstract: The novel bar-code contains counting lines (5, 6), or counting bars (7) in the intermediate spaces (4) between adjacent code bars (1) which are wider than one module width, the module width always being wider than the diameter of the scanning spot (55) of a reader. The line thickness of the counting lines is much less than the diameter of the scanning spot, for example 1/3 of the width of the code bars. The counting bars exhibit a reflectivity which is between that of the intermediate spaces and that of the code bars. Due to these measures, pulses (31) of smaller amplitude than the pulses (30) formed by the code bars are produced at the location of the counting lines or counting bars at the output of a light receiver (9) of a reader. This forms a counting clock which makes the decoding independent of the scanning rate. <IMAGE>
