Patent DE-3700315-A1 (DE)
Title: Large-surface-area heat exchanger
IPC: E04D13/18
Filed: 1987-01-05
Abstract: The application relates to a heat-exchanger system which, by means of a heat pump, obtains ambient heat from the outside air in an extremely simple manner. The application is, at the same time, a structural part which renders a roof structure comprising wooden beams unnecessary. The application is, furthermore, a system which, in addition to the two abovementioned properties, cuts down on extensive roofing work. Moreover, the system contains full heat insulation and sound insulation with the further property that heat losses from the roof inner surface are immediately re-absorbed by the heat exchanger. A vast reduction in construction time for new and old buildings - in conjunction with considerable savings in costs and materials - guarantees commercial success.
Patent DE-3701130-A1 (DE)
Title: Arrangement for locating leaks in flat and sloping roofs
IPC: G01M3/16
Filed: 1987-01-16
Abstract: The invention relates to an arrangement for locating leaks in flat or sloping roofs with a test circuit which can be connected by one pole to the moist point detected under the flat or sloping roof and by the other pole to the top of the flat or sloping roof. A simple arrangement with unambiguous indication of the located leak, independently of the state and structure of the flat or sloping roof, is obtained in that the one pole is securely connected in an electrically conductive fashion to the moist point as a plate-shaped electrode, in that the other pole is constructed as a moisture-storing, porous search electrode with which the upper side of the flat or sloping roof can be sensed, and in that an evaluation circuit is included in the test circuit, which evaluation circuit optically and/or acoustically displays the maximum current within the test circuit and/or the transition from a current rise to a current drop as a signal for the location of a leak.

Title: Method for photothermal materials testing on samples having rough or uneven surfaces, by means of the Mirage effect
Inventor: PETRY HARALD DR
IPC: G01N21/17
Filed: 1987-03-28
Abstract: In order to carry out photothermal materials testing on rough or uneven surfaces with the aid of the Mirage effect, it is necessary to compensate for changes in distance which are caused during the scanning between the scanning beam and the sample surface as a result of the condition (nature) of the surface and which influence the signal. This is achieved by optically determining the change in distance and by refocusing the light beam to minimal spot size with the aid of a motorised lens. The length of travel of the refocusing is assigned by computer to a signal change known from laboratory tests and can thus be separated from the signal changes due to the condition of the material.

Patent DE-3714001-A1 (DE)
Title: Ski binding
Inventor: PAVLOVEC RADKO
IPC: A63C9/00
Filed: 1987-04-27
Abstract: Ski binding component, especially front jaw. The locking devices which are provided in ski binding components and each of which permit the adjustment of the ski binding component on the guide rail are unsuitable for single-handed operation. In adjusting the binding component on the slope, the skier has to undertake tedious manipulations and often have an unreasonable degree of skill. The novel ski binding component is to be conveniently adjustable with one hand. With regard to simple one-handed operation, a control surface (9) extends transversely to the lifting direction of the locking part (5), which has an ascent corresponding at least to the depth of engagement of the locking part (5), and furthermore there rests on the control surface (9) a counter-surface (11) which, when the actuating member (6) is moved, is slidingly guided on the control surface (9), the lifting-out movement of the locking part (5) being controlled in the course of the relative movement between the control surface (9) and the counter-surface (11). The user needs only to move the actuating member in order for the locking part to be lifted out, so that the ski binding component can be displaced with one hand. The actuating part can also be moved with a thick glove. The user need pay no attention to the movement of the locking part. The ski binding component is suitable, because of the simple one-handed operation during adjustment, especially for comfort-conscious skiers and also for skiers who have relatively little manual dexterity. <IMAGE>

Patent DE-3728318-A1 (DE)
Title: DC/DC converter output stage
Inventor: KNAPPE EDUARD
IPC: H02M1/40
Filed: 1987-08-25
Abstract: The DC/DC converter output stage is used in electrical power supply technology. It operates at high efficiency with a low input voltage and offers improved functional reliability at a high output current. This is achieved by the collector of the transistor switch (1), which is operated in saturation, being connected to the base of the depletion resistor (7) via the single-phase differentiating element (3) which improves the switching response. The base current is taken from the primary winding (23), via the driver (6), in order to reduce the drive losses. The clamping diode (4) between the base of the driver (6) and the demagnetising diode (5) prevents magnetic saturation of the transformer (2) as a result of the flyback phase being extended in an optimized manner. The demagnetising winding (21) is connected between the output Ua and the demagnetising diode (5), which is arranged on the earth side. The demagnetising energy is transmitted to the output. <IMAGE>

Title: Fusion vessel with field arrangement for the enclosure of charged particles
Inventor: HOERL NORBERT
IPC: H05H1/03
Filed: 1988-02-22
Abstract: This arrangement for the enclosure of charged particles and plasma consists essentially of the arrangement of 6 sources and 6 sinks in space. The emergent field lines form approximately cubic parabolas. A "field line free hollow space" is formed. If charged particles are now in this "hollow space" or are introduced, then they are compressed by means of the repulsion forces of the sources and sinks. If now these repulsion forces of the sources/sinks are stronger than the repulsion forces of the charged particles and they act simultaneously and uniformly, the charged particles are compressed on all sides and compelled to fusion. The sources are mechanically interconnected and braced.

Title: Keyboards for electronic systems - use series of parallel fibre optical conductors with single light conductors with single light transmitter, etc.
Inventor: RODRIGUEZ PEDRO
IPC: H03K17/969
Filed: 1988-02-25
Abstract: In visual electronic switches and keyboards the logical operations use optical fibres of e.g. glass, acrylic, ''Plexiglas'' (RTN), etc., and interrupt or divert the light beams through them; the optical conductors are arranged parallel in bundles for signalling with a number of bits so that the switches are in rows (e.g. for a keyboard) and only require one single light transmitter; more may be needed in exceptional cases but only one for one row of switches or keys. The optical conductors are preferably made partly or completely by injection moulding (sic). ADVANTAGE - The system is an improved and technologically simplified type of keyboard, etc.
Patent DE-3806390-A1 (DE)
Title: Telescopic cylinder system
Inventor: HUNGER WALTER
IPC: B66C23/70
Filed: 1988-02-29
Abstract: The invention relates to a telescopic cylinder system with several single-stage or multi-stage hydraulic cylinders connected to one another, in which the oil supply for the piston-base side is effected through the hollow piston rod and a central pipe through the piston base via external pipelines to the other cylinders. In order to ensure that, although common admission of oil to all cylinders is simultaneously possible, the effective piston areas can also be acted upon here independently of one another, it is proposed by the invention that the lines through all cylinders be continuously connected and that the pressure spaces be acted upon via separately and hydraulically power-actuated valves which are connected in parallel with the central pipelines. All individual cylinders can thereby be entirely of the same design so that a modular system with any number of cylinders can be set up without changing the individual cylinders. Electronic remote control can also be used, which enables the trailing lines to be completely dispensed with. The system is preferably used in mobile cranes.
