Patent DE-3041625-A1 (DE)
Inventor: PELZ DIETER ING GRAD
IPC: H01P1/208
Filed: 1980-11-05
Abstract: In the case of a folded microwave filter, additional coupling is intended to be achieved between resonators, which cannot electrically follow one another directly, in order to produce damping (attenuating) poles. This additional coupling is produced by a narrow slot (10) in the common separating wall (9) between two resonators (2, 5) by means of a conductive pin (11) which is arranged in front of and parallel to said separating wall (9) and transversely with respect to the slot (10), is somewhat more than one quarter of a wavelength long and is connected at one end to a wall (12) which is at right angles to the separating wall (9), the pin length still being adjustable even after the filter has been assembled. <IMAGE>

Title: Yield of diesel fuel from Fischer-Tropsch reaction increased - and ageing rate reduced by increasing pressure and reducing temp.
Inventor: EISENLOHR KARL-HEINZ DR ING
IPC: C10G2/00
Filed: 1980-11-12
Abstract: In the Fischer-Tropsch process with synthesis gas on a fixed-bed pptd. catalysts contg. Cu and Fe, the yield of diesel oil is raised and the rate of loss of catalyst activity reduced by raising the operating pressure from about 25 bar to a max. of 100 bar (pref. about 50 bar), and simultaneously reducing the temp. to preserve about the same conversion. The rate of loss of activity can be reduced to less than 0.2% conversion/day by reducing the temp. by 10-30 deg.C. With increasing operating time at the normal operating pressure of about 25 bar, not only is conversion lost, but the proportion of prod. boiling below 200 deg.C, i.e. of non-diesel oil prod., rises. This change of prod. compsn. is considerably reduced by the claimed increase of reaction pressure.

Title: Process for operating heating systems and heating system serving for carrying out this process
Inventor: SCHWANEWEDE FRITZ
IPC: F23K5/20
Filed: 1981-03-19
Abstract: The invention relates to a process for operating heating systems, in which heat is generated in at least one burner by the combustion of fuel oil and is used to heat water or another comparable heat-transport medium, for example in a heating boiler. This process provides for preheating the fuel oil before it enters the burner in order to reduce its viscosity. The invention also relates, moreover, to a heating system for carrying out the new process. In this heating system, there is provision for it to contain a treatment unit which is inserted into the path of the fuel oil from the supply tank to the atomiser and acts in the manner of a heat exchanger and through which the fuel oil to be treated flows, on the one hand, and to which heating energy serving for preheating is fed, on the other hand, whilst, within the treatment unit, the fuel oil can come into heat-exchanging contact with the transport or transfer medium containing the heating energy. <IMAGE>

Title: DC motor without a commutator
Inventor: MUELLER ROLF DIPL ING DR ING
IPC: H02K29/08
Filed: 1981-03-28
Abstract: A two-pulse DC motor without a commutator and having auxiliary reluctance torque is constructed such that it can start forwards or backwards from its stable quiescent position (81) and emits approximately the same torque form on its shaft in both rotation directions. For this purpose, the airgap is constructed symmetrically in the manner shown in the projection in Fig. 4A. Since, in the event of severe friction, the rotor can stick even in an unstable quiescent position (82 or 87), care is taken that, during switching on in this position, the rotor (12) receives an additional torque pulse through an auxiliary winding which is offset with respect to the other stator windings, and that this auxiliary winding is subsequently no longer live. An additional circuit is used for this purpose. <IMAGE>

Patent DE-3123060-A1 (DE)
Title: Pipe for high temperatures
Inventor: FALKE ERICH
IPC: F16L57/00
Filed: 1981-06-11
Abstract: On pipes which are subject to high stress resulting from heat, pressure and/or radiation, the occurrence of cracks is often assisted by the wall thickness being overdimensioned because of safety requirements. This is because the expansion stress is increasingly exacerbated with its thickness. More suitable materials are being looked for in order to avoid cracks. As a supplement to this, and in order to reduce the said stress, the present invention recommends a pipe whose wall consists of at least two layers (pipes) which lie one above the other and can be displaced axially with respect to one another when heat expansion occurs. In consequence, the said stress is reduced and thus the risk of fracture. The figure shows on the left the case in which the overpressure p in the pipe prevails. The pipe (1) can slide in the flange (2) and is sealed at (3). Short pipes (4) are pushed onto (1) in an unsealed manner. Elastic intermediate elements (for example spring washers) are located at (5). The pipes (4) support the pipe (1). On the right-hand side, the overpressure p is intended to be outside the pipe. The closed pipe (4) can slide on the pipe (1) and in the flange (2) and is sealed at (6). <IMAGE>

Title: Method of operating a district-heating network and district-heating network designed for the method
Inventor: BRUNS PAUL-HEINZ
IPC: F22D11/00
Filed: 1981-07-14
Abstract: In a method of operating a district-heating network and a district-heating network designed for the method, with at least one heating-heat works generating heating heat, at least one industrial installation generating waste heat, and a large number of heat consumers which are interconnected by a pipe network filled with a heat-transfer medium, it can be possible, depending upon the season, that the waste heat generated by the industrial installation represents an oversupply of heat. In order to supply this oversupply of waste heat to a profitable use by means of the district-heating network, the excess heat is according to the invention, in the case of such an oversupply of waste heat from the industrial installation in relation to the heat demand of the consumers connected to the district-heating network, fed into at least one steam-generating system. Preferably, the excess heat is fed into the feed-water preheating system of a power station or into an industrial network having a steam generator. <IMAGE>
Patent DE-3137521-A1 (DE)
Title: Water tube boiler
Inventor: WIESER RUDOLF DR
IPC: F23C6/00
Filed: 1981-09-22
Abstract: The invention relates to a water tube boiler, the firing of which is changed over from oil or gas to coal-dust. The main aim of the invention is that the nominal steam-generating capacity of the boiler and the steam conditions (pressure, superheating temperature) at the boiler outlet are the same after conversion as before firing change-over. In order to take into account the requirements for lower combustion-chamber loading and reduced smoke-gas speed in the contact-heating surfaces, and in order to take into consideration the greater smoke-gas quantity in the case of coal-dust firing, the original oil-fired or gas-fired water tube boiler is equipped with one or more precombustion chambers and one or more downstream heating surface blocks. Additionally, to reduce the incidence of fly ash in the combustion chamber, a deflection plate for the flames is arranged in the combustion chamber and tertiary air nozzles are arranged on the combustion-chamber end wall. The firing change-over proposed here can, with careful planning and preparation, be carried out on medium-sized boilers during a summer period. <IMAGE>

Title: Optical fibre control system for missiles
Inventor: TEINZER HARALD
IPC: G02B6/44
Filed: 1981-11-12
Abstract: The optical fibre control system for missiles consists of a television camera which is located in the missile, an optical fibre via which the target image is transmitted in digitised form to the control point on the ground, and control spectacles which are worn by the controller. The control spectacles are designed such that on one side of the eyes is a miniaturised television tube (cathode ray tube) on which the target image is generated, and an optical system having variable optical transparency and an adjustable dioptric strength is mounted on the other side of the eyes of the control spectacles. A controller with control spectacles thus has the possibility of observing the surroundings normally through one eye and to have with the other eye the impression of being in the missile. This combination puts the controller optimally in the position of detecting a rapidly moving target with the normally seeing eye, of launching the missile, and of bringing the missile to the target with the other eye, which sees the target image. Advantages of the invention:   - relatively simple, handy and accurate control system even for rapidly moving targets,   - target can be detected rapidly and the defence can be initiated, - operation and, moreover, transport of the missile can be carried out by one person. r

Abstract: The brake unit for friction brakes, in particular block brakes of rail vehicles, has a double-walled brake lever (8a, 8b) in a housing (1). The brake lever can be moved by a brake motor and is mounted pivotably on the housing (1) close to its bottom end by means of its pin support (9). At a position slightly offset from this, the brake lever is connected in articulated fashion by means of a further pin support (10) to an output member, which preferably has a slack adjuster (12). The pin support (10) has pins (16) integrally formed on the slack adjuster (12), their length corresponding to approximately half the depth of the bearing bores (17) in the brake lever cheeks (8a, 8b). Machined into the cheeks (8a, 8b) to the side of the slack adjuster (12) are grooves (21) which open into that half shell of the bearing bores (17) which is not subject to braking forces, extend forwards away from the bearing bores (17) and are open at the end. The width and depth of the grooves (21) corresponds to the dimensions of the pins (16). Extension pieces (18) which extend the length of the pins (16) at least approximately to the depth of the bearing bores (17) or thickness of the cheeks (8a, 8b) can be attached to the pins (16). The extension pieces (18) can be cup-shaped, allowing them to be slipped into the bearing bores (17) and over the pins (16). The extension pieces (18) permit simple mounting or dismounting of the output member or slack adjuster (12) on/from the brake unit. <IMAGE>
