Title: Film development device
Inventor: OTANI MASAMI
IPC: G03D3/13
Filed: 1981-05-20
Abstract: In a film development device, two processing paths for exposed films are provided, the first processing path being used for the transport of conventional films requiring development, stopping, fixing and washing, while the other processing path is used for the transport of "wash films" which only require washing. In their processing path, the conventional films are fed to the various processing stations, while the "wash films" are fed directly to the washing station, missing out unnecessary process steps. The film branch line provided for this purpose for "wash films" is pivotable about a rotation shaft, which simplifies handling of the device. In this way, it is possible to process films of different types in a manner appropriate in each case to the film type by means of a single film development device.

Title: Femoral hip endoprosthesis
Inventor: LINK HELMUT D
IPC: A61F2/36
Filed: 1981-06-30
Abstract: The invention relates to a femoral hip endoprosthesis comprising a stem to be inserted in the medullary cavity of the femur, a support plate terminating the stem proximally and a neck portion starting from the support plate. The lower surface of the support plate intended to rest upon the resection surface on the femur has means for the positive interaction with the bone, the upper surface of which means partially extends at an angle relative to the principal direction of the lower surface. In order to enhance the security of the prosthesis against lateral movements relative to the bone it is provided, according to the invention, that the lower side of the support plates has extensive surface parts which include an acute angle with the direction of the neck part towards proximal/medial and whose negative shape is determined by approximately straight, ventrally-dorsally freely extending generators or whose negative shape is a proximally exposed surface of revolution. These features permit easy and accurate adaptation of the bone resection surface to the shape of the lower side of the support plate.

Patent DE-3136243-A1 (DE)
Title: Inner filter for aquariums
Inventor: EHEIM GUNTHER
IPC: A01K63/04
Filed: 1981-09-12
Abstract: An inner filter for aquariums is proposed, containing an elongated filter cartridge and, mounted thereon in a detachable manner, a head which contains an electric motor with a pump. The filter cartridge consists of individual plug-together module elements of which, depending on the desired length, two or more can be plugged together or can be pulled off, apart from one remaining module element. The head is designed, in terms of its length, its transverse dimension and its external shape, exactly like each module element, the head and the module elements plugged together with it forming an approximately rod-shaped compact element which is continuous in the longitudinal direction. The head and the plug-together module elements may have a cylindrical shape or preferably a polygonal external shape, especially octagonal shape. At the same time, the head and the module elements, and/or the module elements amongst themselves, can be plugged together in such a way that they are offset relative to one another in the circumferential direction about the longitudinal axis, as the user chooses. The lowermost module element is sealed in the bottom zone by a slip-on sealing cover.
Patent DE-3139453-A1 (DE)
Title: Four-place digital revolutions counter for use in motor vehicles
Inventor: STEPANSKI HELMUT ING GRAD
IPC: G01P3/48
Filed: 1981-10-03
Abstract: The invention permits four-place digital rotational speed measurement in passenger cars and trucks both with petrol engines and with diesel engines. The digital revolutions counters available to date mostly permit only a two-place display. This is unsatisfactory, above all in the low rotational speed range. The problem resides in generating a high pulse sequence proportional to rotational speed. The frequency mostly obtained at the contact-breaker point is too low for this purpose. There is a plurality of possibilities for generating a high frequency proportional to rotational speed, but most methods are accompanied by technical and/or economic disadvantages. The solution is, then, to obtain pulses from the generator by transmitting the three-phase alternating current, which is present before the bridge rectifier (Figure 1), into the display electronics optoelectronically. It is now possible in this way to obtain, e.g. by using only one phase, 2400 instead of 200 pulse/sec. The technical outlay for this is very low, and owing to the optoelectronic coupling this method is largely interference-free. Apart from rotational speed measurement, the invention can also be used as a digital speed limiting device. <IMAGE>

Title: Bistable hinged-armature relay
Inventor: MEINHARDT JUERGEN
IPC: H01H51/22
Filed: 1981-10-10
Abstract: In a bistable hinged-armature relay, a main magnetic circuit and an auxiliary magnetic circuit are made functionally effective separately, by means of a permanent magnet. The retention force for the armature in the main circuit is determined by the change in the reluctance in the auxiliary circuit. The switching processes are initiated by superimposing an electromagnetic field on the permanent-magnetic field. <IMAGE>
Patent DE-3209345-A1 (DE)
Title: Active frame antenna with transformer coupling
Inventor: LINDENMEIER HEINZ PROF DR ING
IPC: H01Q7/00
Filed: 1982-03-15
Abstract: An amplifying, electronic three-pole network is coupled to a single-winding frame antenna with the aid of a transformer. In this case, it is intended to exceed a required signal-to-noise ratio over a broad band within a specified frequency range, with frame dimensions which are as small as possible. Furthermore, it is intended that the effective height of the active frame antenna be largely frequency-independent and that the antenna amplifier have linearity properties which are as good as possible. The invention is based on the use of a low-capacity transformer to whose secondary winding an active, electronic three-pole network is connected in a base or in a gate circuit, and the primary side of the transformer is supplied from the single-winding frame. An optimum signal-to-noise ratio is achieved by selecting an optimum transformation ratio for the transformer. Such active frame antennas are preferably suitable for reception in the HF and VHF bands.

Patent DE-3212294-A1 (DE)
Title: Sorption heat pump
Inventor: SCHMID JOSEF
IPC: F25B30/04
Filed: 1982-04-02
Abstract: Sorption heat pump with an evaporator (30) acted on by air and a fuel-heated expeller (10). The evaporator (30) is assigned an air shaft (26), from which the combustion air of the expeller (10) is extracted and in which the waste gas of the expeller (10) is introduced. The extraction of the combustion air takes place at a point of the air shaft (26), at which, in all operating states of the heat pump, the same static pressure as at the mouth of the waste gas line into the air shaft (26) or the same static pressure difference to this mouth prevails. It is thus brought about that the burner operation is independent of external and appliance-dependent influences, e.g. of the icing state of the evaporator which influences the air throughput through the air shaft (26). It is especially advantageous if the waste gas is arranged downstream of the evaporator (30) or of a fan (28) built into the air shaft, because icing of the evaporator (30) and possibly also of the fan (28) by condensate from the waste gas is thus avoided. <IMAGE>

Patent DE-3215577-A1 (DE)
Title: Process and apparatus for solidifying vapours, melts or pastes
Inventor: LIST HEINZ
IPC: B01F15/02
Filed: 1982-04-27
Abstract: Vapours, melts or pastes are introduced, to be solidified, into a stirred and cooled bed of already solidified, flowable product (4). The heat of solidification is removed at the large surface of the product bed, which in turn gives up this heat to the cooled walls of the container (30); the stirrer (32) increases the heat transfer and prevents the formation of lumps during solidification. The container (30) is constructed as a lock-type container, into which the starting product is transferred from an apparatus (20) by means of an endless screw (21) when a valve (23) is opened. When the container is full of solidified product (14), the valve (23) is closed and the container is brought to atmospheric pressure by means of valve (13), so that the product can be brought down to the minimum level (4) after opening the discharge valve (8). After this, in the reverse sequence of operations, the lock-type container (30) is again equalised with the pressure in the apparatus (20), and the process begins again. <IMAGE>

Title: Apparatus for reducing the content of undesired substances in the exhaust gases of an internal-combustion engine
IPC: H01T13/40
Filed: 1982-05-29
Abstract: The invention is concerned with the arrangement of a catalytic converter in the combustion chamber of an internal-combustion engine. The known arrangements of catalytic converters in the combustion chamber of internal-combustion engines have the disadvantage that fastening or adaptation requires the design of the combustion space to be modified. Retrofitting of the catalytic converter in the hitherto known form in the combustion space of the engine is scarcely possible, or only with a considerable amount of work. If it is wished to remove the catalytic converter again, for example for converting to a different type of fuel, this can only be achieved by relatively laborious and time-consuming disassembly. The invention proposes a spark plug in connection with a catalytic converter, it being possible for the body of the catalytic converter to be formed from a gauze, sheet, wire in the form of a cylinder, a hemisphere or the like. <IMAGE>

Title: Substance for the chemiluminescent production of light and processes for this purpose
IPC: F21K2/06
Filed: 1982-06-21
Abstract: Substance for the chemiluminescent production of light, which substance is covered by a film-forming polymer, i.e. is microencapsulated, and processes for the chemiluminescent production of light using such a substance. To initiate the chemiluminescent reaction, the cover is destroyed by mechanical, thermal, chemical or enzymatic action, releasing the substance, which then reacts with other substances by chemiluminescence. Microencapsulated substances exhibiting different luminescent spectra can be mixed in order to produce combined spectra. The course of the chemiluminescent reaction can be controlled by different thicknesses of the cover (capsule wall) and different film-forming polymers. Encapsulation avoids oxidation of the substance, which can also be metered and packaged more advantageously in solid and pourable form.
Patent DE-3227406-A1 (DE)
Title: Colour contrast producer
Inventor: PIAZOLO PIUS DIPL ING
IPC: B44D3/00
Filed: 1982-07-22
Abstract: Even Goethe, some two centuries ago, referred in his scientific works on the study of colour, to the psychological/physiological value of colour contrasts. Even then, therefore, Goethe must have been familiar with this important relationship in considerable detail. Whereas sound, as we know, has its field of reference in the sense of hearing, colour has its field of reference in the sense of sight. The impact of COLOUR is more tangibly structured. Thus, the significance of a time indicator in the sound structure is then, correspondingly, a colour contrast indicator in the colour structure. Dealing with colour contrasts is entirely remarkable. Creative efforts to produce colour contrasts, with the guarantee that spontaneity is retained, can be of assistance to many scientific disciplines. The results achieved in this manner are personalised value forms. Value forms, in other words, which give a clear insight into the psychological/physiological areas of man. This type of creative mechanism, however, requires a corresponding set of instruments. By way of a conceptual principle of form, for example, it is possible to work towards bringing about a visual planned order, in other words this principle can be used to produce a colour contrast relationship which is capable of evaluation. This is precisely what the colour contrast producer achieves. The mode of action may equally well be manual, mechanical and/or electronic.
