Title: Boiler combustion chamber shaft walls - have cooled pipes extending down to distributor pipes adjacent combustion chamber perforated base
Inventor: KOLLERUP VAGN DIPL ING
IPC: F23C10/00
Filed: 1980-10-21
Abstract: The boiler combustion chamber (1) contains one or more vertical shafts (9) which are closed gas-tight at the top and issue at the bottom over the topside (8) of the eddy layer. The shaft walls (10) contain fluid-cooled pipes (12,13) which continue down through the eddy layer to distributor pipes (17) near the chamber's perforated bottom wall (3). The shaft's total cross-sectional surface is so much smaller than the eddy layer's top side that exhaust gases from the layer can flow upwards without hindrance through the combustion chamber between the shaft walls and the boiler's side walls (2'). Cooling of the shaft walls prevents ignition of fine fuel particles over the eddy layer, and permits usage of mechanical fuel feed extending across the whole combustion chamber's length.

Title: Warp-beam carriage
Inventor: DITSCHERLEIN FRIEDHOLD
IPC: D03J1/00
Filed: 1981-07-31
Abstract: The invention relates to a warp-beam carriage, with lifting arms (13) which are mounted on a chassis and are designed for carrying a warp beam (16) and which can be pivoted up and down relative to the chassis by means of a hydraulic cylinder (17). The chassis has a longitudinal spar (1) and transverse spars (11) arranged at its ends and equipped with running wheels (12), a lifting arm being assigned to each of the two transverse spars. The lifting arms are mounted on the chassis so as to be pivotable relative to the transverse spars about an axis (10) parallel to the longitudinal axis of the longitudinal spar and can be pivoted up and down relative to the transverse spars by means of the hydraulic cylinders. So that the warp-beam carriage, whilst having as good travelling properties as possible, takes up relatively little space and can easily be stowed, according to the invention at least one of the two transverse spars (11) is fastened to the longitudinal spar (11) so as to be adjustable, preferably continuously, in its longitudinal direction. At the same time, there can be seated above the adjustable transverse spar the lifting arm which is assigned to the latter and which is likewise adjustable together with the transverse spar on the longitudinal spar and is supported on the transverse spar so as to be pivotable up and down via its own hydraulic cylinder. <IMAGE>

Title: Universal-joint support for spades and forks
Inventor: TATZEL FRANZ
IPC: A01D11/00
Filed: 1981-10-19
Abstract: By means of the universal-joint support, digging work with spades or forks is, as in the devices and supports known hitherto, made easier by a lever-like lifting of the clod. However, the working range is extended and the amount of force exerted reduced by the type and arrangement of the universal joint and rotary foot. The universal-joint support is firmly screwed in a clip-like manner to the handle with a lever ratio of 1:2-3. The universal joint is advantageously arranged with its centres of rotation below the handle mid-axis; thus, the tipping over of the lifted-out clod is assisted by the clod weight. The lower square pivot of the rotary mounting of the universal joint projects with its upper corner into the fork piece and with its end face determines the basic position of the support. The corner serves as a catch for the basic position and forms a lateral tilt safeguard when the clod is being lifted out. The rotary foot having a soil scraper removes adhering soil as a result of a rotation of the foot. The support can be detached by pulling out the cotter or can be swung up along the longitudinal side of the handle and fixed. <IMAGE>

Title: Navigation method for vehicles
Inventor: OLBRICH BERND DIPL ING
IPC: G01C21/22
Filed: 1981-11-25
Abstract: The invention relates to a navigation method for vehicles which have a course reference device, for example a course gyroscope for generating a course signal and a distance sensor. Using compound navigation, the position of the vehicle during the trip is indicated on a map and the direction of the course is indicated on a course compass. According to the invention, the north direction reference is established at the beginning of the trip by establishing on the map the location A of the vehicle and a further terrain point B which can be seen from the vehicle and determining a first angle  alpha between the north-referred grid lines of the map and an imaginary line between the points A' and B' on the map. Furthermore, the north direction of the course compass is set parallel to the longitudinal axis of the vehicle and the course pointer on the course compass is aligned with the terrain point B. The angle  beta  between the course pointer and north direction, indicated on the course compass, and the first angle  alpha , additively combined, form the vehicle direction referred to the north direction.

Patent DE-3149838-A1 (DE)
Inventor: LUCHT FRIEDRICH
IPC: B63H9/06
Filed: 1981-12-16
Abstract: A sail with a tubular portion is pulled over a mast and/or a stay of a sailing vessel. The tubular portion is inflatable through a sail mouth opening at the fore leech thus forming an air envelope of the sail due to the relative wind effects. A plurality of telescoping contour sleeves formed of a lightweight, floating, elastic material are arranged in the tubular portion and sheath the mast and/or stay as well as selected portions of the rigging. The formation of an air envelope from a part of the sail and the use of rotatable streamlined contour sleeves inhibit complete heeling over of the sailing vessel and simplify the erecting of surfboards and sailboats. The telescoping arrangement of the contour sleeves permits an alteration of the sail surface and the sheathing of the rigging further decreases the wind resistance leading to an increased speed capability without need for greater inclination of the vessel. Thus the sails are better able to utilize the wind energy.

Patent DE-3203409-A1 (DE)
Title: Spring assembly
Inventor: WANKE KLAUS DIPL ING
IPC: F16F3/04
Filed: 1982-02-02
Abstract: The invention relates to a spring assembly subjected to compressive loading, in which it is unnecessary to make the inner spring, in particular, buckle-resistant. The aim of the invention is to create preconditions to ensure maximum loading of the springs of a spring assembly with the minimum installation space, without increasing the outlay. This aim is realised by virtue of the fact that, in such a spring assembly and with a different direction of winding of the outer and the inner spring, one or more coil groups with closed and/or slightly open coils are arranged on the inner spring in such a way that they divide the buckling spring into two or more buckle-resistant elements.
