Title: Transformer assembly of push pull saturating inverter - has core construction with cross section of centre limb which is locally reduced
Inventor: SCHIERJOTT RUDOLF
IPC: H01F3/14
Filed: 1980-03-07
Abstract: The transformer core design is used to reduce the magnetising losses and increase the efficiency of the inverter particularly at partial load. Inverters of this type are used to provide galvanically isolated dc supplies from a common dc source. The ac intermediate stage typically operates at several kHz. The required efficiency can be obtained by locally reducing the cross-sectional area of the centre limb (MS) of the transformer core (K). The reduction is made by cutting away the core material on one side (SA), typically by grinding. A particularly effective design results when the transformer is made from two E-cores whose limbs butt together. Only one centre limb need be ground away. In addition to reducing the losses, the change in cross section also assists in determining the oscillation frequency.

Patent DE-3030305-A1 (DE)
IPC: F23B30/06
Filed: 1980-08-11
Abstract: Solid fuel such as coal is fed into an inlet shaft of the furnace through a rotary feeder constructed to prevent the admission of air. Primary air channels supply the major part of the air required for combustion of the fuel in a region in which the fuel bed is sufficiently thick to avoid disturbance and the formation of "holes" by this air. Further, narrower air channels supply sufficient, diffused and low velocity air to complete the combustion of the fuel without substantial entrainment of grit and ash. Air is prevented from flowing in contact with the fuel up stream of the primary channels and the metering edge.

Patent DE-3102277-A1 (DE)
Title: Filter having sprayed-in sorbent
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/34
Filed: 1981-01-24
Abstract: The invention relates to a filter having sprayed-in sorbent. The object is to achieve as high a chemisorption as possible and to re-split already formed agglomerated particles and to achieve a sorbent coating on the filter cloth having as large a surface area as possible per gram of active component injected. According to the invention this is achieved by arranging in the region of the contact section inlet(s) chemisorption injection nozzles which inject chemisorption agents against and/or with the gas stream, which chemisorption agents work with the gas stream. In the inlet region of the contact section in the filter housing itself or in an expanded region of the contact section a nozzle arrangement is mounted which produces an impact effect of the already agglomerated chemisorption compositions and with the effluent gas stream the finest particles extensively occupy the filter surface coat with the lowest possible weight and surround the already agglomerated particles with another active layer.

Patent DE-3108802-A1 (DE)
Title: Device for anchoring a tensioning bar and for transferring the anchor force to the concrete
IPC: E04C5/12
Filed: 1981-03-07
Abstract: The invention relates to a single-part anchor body for tensioning-force transfer between threaded tensioning bars and concrete. The anchor body represented in the drawing comprises a threaded steel sleeve (1) in the centre of a cone shell (2) which opens towards the supporting surface (1). In the standing region (3), the cone shell (2) is reinforced annularly. Known single-part anchor bodies comprise thick steel plates with central threaded bore. They are sensitive with respect to thread tolerances, and, in particular on the first load-bearing thread turns, overloading and carrying-force losses occur. In order to achieve a uniform concrete-surface compressor stress, a large, uneconomical thickness is required. These disadvantages are avoided according to the invention in that a threaded sleeve is supported by a cone shell only in the upper third of its height. In the sleeve region subjected to tensile loading, there is a balanced force transfer between sleeve thread and bar thread, and, in the upper sleeve region subjected to compressive loading, the bar is clamped and this reduces sensitivity to tolerances. In the same way as high permissible part-surface compressor stresses on the standing ring, pure tensile and compressive loadings in the anchor-body elements result in savings in materials. <IMAGE>

Title: Method and device for converting fuel heat into mechanical energy
Inventor: POCRNJA ANTON DIPL ING
IPC: F02B37/00
Filed: 1981-08-03
Abstract: A method for converting fuel heat into mechanical energy in an internal combustion engine is specified. In this a compressed, gaseous working medium is admitted into a combustion chamber in a periodic sequence and burnt together with fluid which is fed in and serves for combustion of the working medium. The reaction gases formed in the combustion expand as they are released and expelled from the combustion chamber. In order to be able to convert the energy contained in the fluid, the fuel energy, into mechanical energy with greater efficiency than in known internal combustion engines, the gaseous working medium is fully compressed or compressed almost to compression pressure outside the engine, heated and admitted into the combustion chamber.
