Patent DE-3231561-A1 (DE)
Title: Gas turbine with low heat losses
Inventor: HAGEN HERMANN DIPL ING DR TECH
IPC: F02C6/00
Filed: 1982-08-25
Abstract: In gas turbines with shaft power output known hitherto endeavours were made to optimise the thermal efficiency and thereby the specific fuel consumption by means of an advantageous operating process. To this end either a high compressor pressure ratio is accomplished together with the highest possible turbine inlet temperature or a heat exchanger, which partially uses the exhaust gas heat to heat up the compressor air, is used to reduce the waste heat loss. According to the invention the waste heat, as in steam turbines, which have condensers, is further utilised in the gas turbine in that the exhaust gases are expanded below the level of the inlet pressure (atmospheric pressure), and then passed through a cooler and are recompressed to the inlet pressure in an exhaust gas compressor. Since in expansion to the low pressure more energy is given off than is required for recompressing, excess energy remains which is additionally available to the gas turbine and improves the thermal efficiency. Gas turbines of this type can be built as single or double shaft machines and are probably suitable for vehicle, ship or aircraft engines and also for power station plants. <IMAGE>

Patent DE-3311267-A1 (DE)
Title: Fuel injection device, especially for a multiple cylinder, spark ignition internal combustion engine
Inventor: PFEFFER VIKTOR DIPL ING
IPC: F02M69/08
Filed: 1983-03-28
Abstract: The invention relates to a fuel injection device, comprising liquid nozzle and mixing nozzle, especially for multiple cylinder, spark ignition internal combustion engines, in which fuel under pressure is fed centrally to a chamber into which gas, especially air, also flows by way of a feed line connected to the nozzle body of the mixing nozzle and with the fuel forms a fuel-gas mixture which emerges from the end of the nozzle bore of the mixing nozzle at the speed of sound. In order to obtain an improved atomisation efficiency at the outlet of the nozzle bore of the mixing nozzle, the gas is fed tangentially into the chamber designed as a swirl nozzle, the gas being mixed with the fuel in the nozzle bore. As a result a film of liquid which would lead to large liquid droplets on leaving the nozzle bore does not form on the mixing nozzle.

Patent DE-3320265-A1 (DE)
Title: Tube-in-tube heat exchanger
Inventor: HAMPEL HEINRICH DR ING
IPC: F28F1/02
Filed: 1983-06-04
Abstract: The tube-in-tube heat exchangers known to date, which are built from round tubes placed centrally, or else non-centrally, in one another, and form straight or spiral tube bundles, give rise in production to a number of design as well as construction problems. It is the object of the invention to develop a compact tube-in-tube heat exchanger which is very effective in terms of heating engineering and can be used for a plurality of functions (cooler, condenser, evaporator, preheater). This is achieved when a smooth tube or a tube with an annular, spiral corrugation is mounted in the interior of the enclosing tube, this enclosing tube having an oval or elliptical cross-section. Owing to this shape of the outer tube, the inner tube is seated firmly by means of punctiform, linear, or else areal contact of the two tubes. Vibrations are reduced to a high degree. The performance of tube-in-tube heat exchangers designed in this way is also enormously increased, owing to the turbulence of the medium, which is particularly promoted by the design.

Title: Machine for the automatic tumbling of skins
Inventor: PRETTO PAOLO
IPC: C14C15/00
Filed: 1983-10-04
Abstract: A machine for the automatic tumbling of skins has an outer cylindrical drum and an inner cylindrical cage, into which the skins to be treated and additives necessary for this are introduced and in which the processing of the skins takes place as a result of the rotation of the apparatus as a whole in a predetermined direction of rotation, the skins and additives being combined by virtue of a special design of the apparatus inside the cage. When the direction of rotation is reversed, the additives move to the rear part of the apparatus, whilst the skins move in the direction of the front part of the apparatus, with the result that a separation of the skins and additives from one another and finally the discharge of the skins from the drum can be brought about.

Title: Method of producing thin-film field-effect cathodes
Inventor: REICHLE MICHAEL DIPL PHYS DR
IPC: H01J9/02
Filed: 1983-11-11
Abstract: To simplify the production of precisely defined hole structures for the emission points in a method of producing thin-film field-effect cathodes, all the functional layers, namely the electrode (11), insulating layer (12) and extraction electrode (14), and also auxiliary layers (13, 16, 15) are consecutively deposited one on top of the other in two-dimensionally continuous form and coated with a resist layer (17). The resist layer (17) is used as a mask for etching holes (18) in the functional layers for the emission points (19). The hole-patterned (20) mask is produced by suitably exposing the resist layer (17). The holes (21 to 23) are then produced consecutively in the auxiliary or functional layers by using an etching method and various etchants. Finally, the emission points (19) are produced by vapour deposition of a suitable metal. <IMAGE>

Patent DE-3410872-A1 (DE)
Title: Positively-locking nut securing device
Inventor: LE THANH-SON DIPL ING
IPC: F16B39/10
Filed: 1984-03-21
Abstract: In order to secure a screw connection against loosening on its own, against loss and, in particular, against subsiding, the positive lock between the nut and the screw is formed via a securing part which is integrated on the nut. In this case, the securing part can be connected in a positively-locking manner to the screw directly or via a coupling piece. The securing part is connected elastically or rotationally-elastically via a spring element (for example a spiral rotary spring or a hollow-rod rotary spring) which is constructed on the connecting part between the nut and the securing part, so that said spring element can be rotated through a rotation angle in order to form a positive lock with the screw with respect to the nut. In this case, the spring element is braced in the rotation direction, possibly also in the axial and radial direction, so that, in the secured state, the screw connection continuously experiences a tightening torque which is equal to the restoring moment of the braced spring element, so that the nut or the screw is tightened by this tightening torque, which is stored in this manner, in the event of loosening. The screw connection is also prestressed, possibly by an axial prestressing force which is equal to the axial restoring force of the braced spring element. The positive-locking securing process can be reproduced in any position.

Title: Apparatus for knocking out articles from a mould, in particular for knocking out chocolate articles
Inventor: BENDER HANS-JUERGEN DIPL ING
IPC: A23G1/28
Filed: 1984-03-30
Abstract: In order to knock out articles still adhering to the mould after this has been turned over, vibrators have been used hitherto which set the mould vibrating. However, under certain conditions, not all articles can be reliably and in a sufficiently short time knocked out of the mould in this manner. To remove the difficulties, the invention proposes that the apparatus serving for knocking out is a hammer mechanism which allows a predetermined number of individual blows to act on the mould. In this manner, the mechanical power necessary for knocking out is essentially determined by the size of the impulse. A single blow or at most a small number of blows is sufficient for reliable removal of the articles.
