Patent DE-3300562-A1 (DE)
Title: Obtaining heat by means of spent reactor fuel elements
Inventor: SCHLUDI HARIBERT N DR PHIL
IPC: G21D9/00
Filed: 1983-01-10
Abstract: The spent fuel elements discharged from a nuclear reactor develop so-called afterheat because of the radioactive decay of their fission products. This afterheat is presently dissipated unused to the environment of the power station. The afterheat is not inconsiderable in this case: thus, e.g., the annual amount of fuel discharged in a nuclear power station of approx. 35 tonnes in 2 years produces a quantity of heat of 14.67 million kWh, which corresponds to the thermal energy of approximately 1,800 tonnes of coal. It is proposed according to the invention to use this afterheat. The following possibilities are quoted for the use of afterheat   - hot water production in the power station itself or externally near the consumer   - steam generation in a pressure vessel - provision of process heat in the case of chemical transformations   - provision of heat for heating purposes in dwellings.

Patent DE-3304193-A1 (DE)
Title: Equipment for treating slurry, in particular active cement slurry
Inventor: RIKER RUDOLF ING GRAD
IPC: B03B13/00
Filed: 1983-02-08
Abstract: The invention relates to equipment which enables by simple means a reliable storage, transport and metering of the liquid phase during processing of sludge-containing cleaning waters, for example, active cement paste mixed with dust and very fine substances. The slurry water which contains the cement constituents capable of setting is stored in a buffer vessel having a conical base, the stirrers being vibrated so that the non-clumping concentrated slurry can be withdrawn to the outside from the region of the largest movement. To balance the transported amount of solids (by volume or weight), the set-point scale of a single measuring instrument (volume measuring instrument) receives a second scale on which the solids volume determined by evaporation or the solids weight can be read off. In a development of the inventive conception, a weight and volume measuring instrument is combined and both sensors are coupled via a computer with the aim of automatic weight balancing of water and solids. Various designs of the volume and weight/volume measuring instrument are presented. The change of the program (formula for new mixtures), into which the water and solids values enter, can thus be carried out manually or completely automatically.
Patent DE-3306174-A1 (DE)
Title: Video cassette with copy protection
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: H04N5/913
Filed: 1983-02-23
Abstract: In a video cassette, the recorded colour synchronisation signal (1) is modified by shortening or timed displacement as protection against copying in such a manner that the number of colour subcarrier oscillations is approximately halved during the time (A) it is keyed open. The reference subcarrier oscillator is then still synchronised during replay of the original cassette but is no longer synchronised when a cassette obtained by copying is replayed because of the narrow bandwidth of the colour channel. Colour reproduction is then impossible or disturbed. <IMAGE>
Patent DE-3307875-A1 (DE)
Title: Combination lock
Inventor: GONZALES ESTEBAN
IPC: E05B37/16
Filed: 1983-03-05
Abstract: A programmable combination lock contains keys, as a result of the actuation of which the lock bolting can be released. A bolt is moved transversely relative to the keys and, depending on the position of the keys, can engage in their eccentrically arranged recesses. The keys are now mounted in a return-free manner and can be brought into their initial position by means of a centrally actuable return mechanism. The advantage of this is that the keys can be depressed in succession and remain in their pressed position, thus making operation notably easier.

Patent DE-3328805-A1 (DE)
Title: Corner connection for a frame, in particular a U-shaped door frame
Inventor: SCHMIDT HELMUT
IPC: E06B3/988
Filed: 1983-08-10
Abstract: The invention relates to a corner connection for U-shaped door frames, each connection point exhibiting two connection tongues arranged in the mitre region of the U-legs of the U-shaped frame profiles, which tongues engage in corresponding tongue recesses. With the frame profiles aligned at right angles to one another, the connection tongues can be pushed into the tongue recesses or vice versa by an advancing movement of the relevant tongue profile in the longitudinal direction of said profile, thus forming a snap-fit connection and avoiding a pivoting-in movement, as a result of which in practice a mitre clamping hinge is produced. <IMAGE>

Title: Child's sport vehicle
IPC: B62B9/12
Filed: 1983-09-16
Abstract: The invention relates to a child's sport vehicle with a chassis and a supporting part consisting of a frame and coverings made of flexible textile material, the supporting part being adjustable into a sitting position in which a back part is directed upwards and a base part is directed downwards, and into a lying position in which the base part, seat part and back part are essentially flush with one another. In the lying position, a child's sport vehicle of this kind is also open to the sides in the leg area of the child and at the head area of the narrow wall. With the invention it is intended to design a child's sport vehicle of this kind in such a way that it can be transformed in a simple manner from a sport vehicle into a child's pushchair. This is achieved in that the supporting part is constructed as an essentially enclosed body of the child's pushchair and in that a U-shaped end wall bracket is assigned to the frame of the back part and is connected to the back part and to the seat part in an articulated fashion such that in the lying position of the supporting part it is directed virtually perpendicular with respect to the back part and in the seat position it is directed approximately in the same way as said back part and has a textile cover which is connected to the covering of the back part. As a result, the body of the pushchair is closed in the head region. In addition, in each case longitudinally adjustable suspension elements for textile wall surfaces are arranged on both sides of the supporting part frame between the foot rest and the side members of the seat parts and said wall surfaces are connected to a cover for the foot rest ...

Patent DE-3338402-A1 (DE)
Title: Self-closing shut-off valve
Inventor: PREUSS GUENTER
IPC: F16K21/12
Filed: 1983-10-19
Abstract: The invention relates to a self-closing shut-off valve, the main valve of which is pilot-controlled by a manually actuated auxiliary valve, the object being to make the timing mechanism for the delay closure of the auxiliary valve simpler and less fault-prone and to create the structural preconditions to allow such self-closing valves to be made largely frost-proof. This object is achieved by means of a self-contained two-chamber thrust-piston system which is filled with pressure medium, the pressure medium being, for example, water, which expands when there is a risk of frost and automatically opens the auxiliary valve with the main valve, thereby preventing the flowing water in the pipes from freezing. <IMAGE>

Patent DE-3339824-A1 (DE)
Title: Device for semi-mounting a swan neck on a traction vehicle
Inventor: PREUNINGER MANFRED
IPC: B62D49/00
Filed: 1983-11-03
Abstract: A device serves for semi-mounting a swan neck (13) on a traction vehicle and comprises a saddle plate which is arranged on the traction vehicle and has the function of receiving the swan neck (13) so as to be rotatable about an essentially perpendicular axis (14). In addition, means are provided which exert a force in a resilient fashion counter to the rotation of the swan neck (13) about the axis (14). These means are formed in order to generate a restoring moment of the swan neck (13) over a large rotational range (+/-@) by means of at least two springs, in particular gas pressure springs (52, 53) which engage with their ends on the swan neck (13) and on the traction vehicle. Essentially, only one gas pressure spring (52) is active during a rotational movement (35) out of the longitudinal axis (19) of the traction vehicle in one direction and essentially only the other spring (53) is active in the case of a rotational movement in the other direction (Fig. 10). <IMAGE>
Patent DE-3343587-A1 (DE)
Title: Silencer for flowing gases
Inventor: BEYER MANFRED
IPC: F01N13/18
Filed: 1983-12-02
Abstract: The invention relates to a silencer for flowing gases, in particular for air-operated machines and plant, having a cylindrical housing, at one closed end of which is arranged at least one inflow connection and at the other end of which is provided a large-area gas outlet to atmosphere. In the hollow space of the housing there are one or more chambers with damping filters, which are held by orifice plates which can be inserted removably into the housing by means of retaining rings. The connection plate situated at the end and separate from the housing as well as the orifice plates holding the damping filters are each held on both sides by radially resilient retaining rings which rest in internal grooves in the tubular housing. The silencer is installed in a suspended manner with the connection plate fitted at the top, thereby being particularly well protected from dirt. The advantages are the universal range of applications in air-operated machines and plant, the rapid escape of the exhaust air in order to maintain the cycle times, and the ease with which the damping filters can be removed and replaced in combination with protection from dirt in the pipes but, especially the high degree of noise reduction which can be achieved.

Title: Electronic display panel for selecting types of spare parts or accessories or for setting data or for transport connections
Inventor: SUEHRCKE GUENTHER
IPC: G09B29/10
Filed: 1984-07-11
Abstract: With fundamentally identical principles, the programming of the chips or of the computer is similar. A remedy is provided for the disadvantage of having to select correct spare parts or accessories from lists or books. This selection of data and types can be undertaken, even by those of below-average ability, with a few keystrokes on the electronic display device or panel, for example when selecting spare parts in self-service outlets. Setting data for engines, etc., no longer need to be looked up in soiled books but can be called up by keystrokes as a result of chip control in a display panel. The display panel easily fits any workstation. A constant experience at stations is the difficulty experienced, for example by car drivers wishing to change transport, in obtaining a railway ticket. The same applies to older people. The present invention ensures that, after a clear display of the route and fare prices, a ticket can easily be obtained, especially when the invention is combined with an automatic ticket dispenser. Traffic connections can be read off much more quickly and easily by means of the display device or panel described, with the possibility of selection, than in conventional, unclear time-tables, especially in those which are fed by screen text. The representation of the data and times which have been selected is in liquid crystal ... Original abstract incomplete.

Patent DE-3429727-A1 (DE)
Title: Combustion/steam compound engine with utilisation of process heat
Inventor: BONGERS HERMANN DIPL ING
IPC: F02B3/06
Filed: 1984-08-13
Abstract: In the combustion/steam compound engine comprising the main assemblies: combustion engine, steam engine, steam boiler and heat exchangers, the reduced fuel consumption is achieved in that the combustion air drawn in by the combustion engine and, in the supercharged version, "fed" flows, preheated, into the cylinder of the combustion engine. The air preheating may be performed by the heat exchange with the hot exhaust gases, with the waste steam of the steam engine or with both. As a result the temperature level of the combustion process is raised and the steam produced by the boiling of the cooling liquid and in the gas-liquid heat exchanger thereby experiences a greater heat content. The steam engine connected to the output side of the combustion engine thereby has a greater utilisable temperature gradient available to it.
Patent DE-3429943-A1 (DE)
Title: Method for measuring the distance between target and projectile and proximity fuse for carrying out the method
Inventor: MUENZEL KLAUS
IPC: G01S7/4912
Filed: 1984-08-14
Abstract: A proximity fuse is intended to detonate a projectile before it impacts on the target (21). A transmitter (14) sends out a beam (22) which, reflected by the target, impinges on a receiver (15). According to the invention, interfering influences, for example sunlight which reaches the receiver (15), are eliminated by a distance measurement carried out in four phases. A completely discharged capacitor is first charged up by current (IS + ID) caused by the reflected beam (23) and by the scattered light and then discharged by current (IS) caused by the scattered light. The remaining charge is then compared with a threshold value. If the remaining charge reaches the threshold value, firing occurs. <IMAGE>
