Patent DE-3740443-A1 (DE)
Title: Service pipe, in particular for gas supply
Inventor: ALMERT ADAM
IPC: F16L27/12
Filed: 1987-11-28
Abstract: A service pipe, in particular for gas supply, is composed of a feedline which branches off from the supply network, and of a house line which is connected thereto and is fitted on outside the house. In order to ensure that excessive drawing-out forces, e.g. as a result of earthmoving gear or the like, are transmitted from the feedline to the house line and thus to the house-side fittings and to trigger said safety function in the event of a defined drawing-out force, the feedline is guided such that it can be displaced axially to a restricted extent with respect to the house line and provision is made for a stop which acts at the end of the displacement path, is designed for the drawing-out force, releases the feedline when said drawing-out force is exceeded and, in the event of said drawing-out force being exceeded, ruptures or is deformed such that the connection between feedline and the house line is released.

Title: Method for operating a slipring-rotor machine of a shaft hoist system
Inventor: HEIER KARL-WILHELM DIPL ING
IPC: H02P3/18
Filed: 1987-12-19
Abstract: A slipring-rotor machine (1) of a shaft hoist system can be operated over a wide rotation speed range by means of a three-phase converter (3), whose voltage and frequency can be controlled, in order to move a conveyed load (13) upwards and downwards between various positions. A method is proposed with whose aid the conveyed load can also be held at rest in a desired position, without using a mechanical brake. To this end, at a stator voltage/stator frequency ratio (U/f) which is constant in comparison with rated operation, the three-phase converter is regulated down to low stator voltage and stator frequency values, in such a manner that the rotation speed (n) of the slipring-rotor machine (1) becomes zero, while still producing the required torque. The rotor winding (5) of the slipring-rotor machine (1) can be connected to rotor resistors (6) as a function of the torque (M) which needs to be applied at rest. <IMAGE>

Patent DE-3814134-A1 (DE)
Title: Device for closing an access opening
IPC: E04F11/04
Filed: 1988-04-27
Abstract: The access opening for intermediate floors or flat roofs has, up until now, been closed by a fire-retardant cover which is fixed pivotably on the floor and can be moved only by special manipulation. The danger of the access opening remaining unclosed, for example as a result of forgetfulness, is, in the nature of things, relatively great, with the result that a fire-retardant closure of the access opening cannot be ensured in an absolutely reliable manner. With the aid of the device according to the invention, the intention is to achieve an optimum degree of fire retardation. In order to achieve this, provision is made to arrange the cover (1) on the upper side of the floor (6) such that it closes automatically. In this arrangement, means such as pneumatic springs (5) or the like, which damp the closure movement of the cover (1), are fitted on the floor (6) and on the cover (1). The pivot angle of the cover (1) is < 90@. This ensures that, without closing the access opening from beneath, fire-retardant protection is ensured at all times. <IMAGE>

Title: Alarm devices by means of ultrasonic distance measurement
Inventor: FORSTER ALFRED DIPL ING
IPC: G01S17/931
Filed: 1988-05-16
Abstract: Previous alarm devices detected objects which were in the detection range by means of ultrasonic distance measurement. However, to avoid approaching or departing objects causing danger it is advantageous if the distance or the approach of objects is detected by means of an alarm device. The relative movement between the alarm device and the object is detected by evaluating cyclically successive distance measurements, that is to say the sensor signals. Two subsequent sensor signals of the sensor (1) are in each case stored in two signal stores (3 and 4) and routed to a comparator (5) for comparison. An evaluation unit (7) controls, as a function of the output signal of the comparator (5), a signalling unit (6) for displaying the relative movement. The alarm device is particularly suitable in vehicles for avoiding a reliable approach to objects during reversing. <IMAGE>

Patent DE-3830244-A1 (DE)
Title: Container closure
Inventor: BUERKLIN GUENTER
IPC: B65D41/14
Filed: 1988-09-06
Abstract: A container closure (1) (Figure 3) has a lid (3) which is fitted over a bead-like opening edge (4) of a container (2) in the closed position. The lid (3) can consist of an aluminium strip on which a layer (5) of sealing material, which is more elastic than the lid material, is applied on the inside over the entire surface. In this case, the sealing material can consist of foamed plastic or of rubber-elastic material. By means of this design of the lid (3), a tight closure of the container (2) is achieved with simultaneously simple removability of the lid (3) by hand. Since there is no bonded connection between the lid (3) and the container (2), the lid (3) can be removed from the container (2) in one piece and thus without residue. The container closure according to the invention is therefore particularly suitable for reusable containers because, as a result, complex preparation work is not required in this case as is otherwise required when removing closure residues from the container.
Patent DE-3837986-A1 (DE)
Title: Supporting structure for conveyor bands
Inventor: POHLE HELMUT
IPC: B65G21/14
Filed: 1988-11-09
Abstract: A supporting structure provided for conveyor bands is suitable especially for use with storage-band loops and similar belt-type storage devices, because the supporting spars and therefore the individual portions of the supporting structure are designed to be capable of being pushed telescopically in one another. The individual roller holders for the carrying-run and return-run rollers are designed as roller mounts connected releasably to the supporting spars, so that they can be assigned respectively to a telescope of this type which can be extended individually or in succession in order to lengthen the supporting structure. Conversely, it is possible, in turn, to displace a respective individual telescope or else all the telescopes in succession, in order thereby to shorten the supporting structure correspondingly. The individual telescopes or the supporting spars capable of being pushed in one another are assigned rollers which roll respectively in the larger telescope, so that an advantageous ease of movement of the telescopic supporting structure during extension and retraction is guaranteed. <IMAGE>

Title: Connection structure for cantilevered extensions on buildings, in particular balconies
Inventor: SATTLBERGER HANS
IPC: E04B1/00
Filed: 1988-12-21
Abstract: Such cantilevered extensions, for example, for balconies are usually retained by a horizontal tie rod which is supported on an adjacent floor of the building and is secured on the load-bearing member by means of screw-bolts which pass vertically through the entire load-bearing member and are to be secured via nuts. In order to provide a simpler and, in addition, externally more attractive possible construction, the invention provides that the tie rod (9) runs preferably in a sloping manner in a cutout or bore (13) in the load-bearing member (5) and leads to an anchor plate (17) which is introduced in said load-bearing member (5) and on which it is fixedly anchored and supported. The connection structure is suitable, in particular, for timber balconies. <IMAGE>

Patent DE-3903788-A1 (DE)
Title: Acoustic sensor
Inventor: NESTEL SIEGFRIED DR ING
IPC: G01V1/00
Filed: 1989-02-09
Abstract: It is common, for example in object protection and in remotely-steered flying objects, to use specially purpose-designed microphones for sound measurement location, by means of which conclusions can be drawn about the direction of a sound pressure and, from its intensity, about the distance of the sound source. In the case of an increased velocity relative to the ambient air, even microphones arranged optimally with respect to flow technology have an inherent noise spectrum which lies in the audible range and therefore overlays the useful signals to be detected. The invention provides as a sensor an optical fibre (4, 5), reacting to sound pressure and clamped transversely, longitudinally or obliquely to the relative movement direction. Mechanical pressure changes acting from outside are indicated by means of changes in the phase and amplitude of the radiation in the fibre. Because of the very low diameter of the optical fibre (4, 5), the inherent noise spectrum lies in the ultrasonic range and thus distinctly remote from the audio-frequency useful signal spectrum. To improve the signal to noise ratio, large area sensors are conceivable in which the optical fibres (4, 5) are interlinked to make flat structures. <IMAGE>

Title: Method for the digital and/or analog coding of information of one, two or more channels and/or frequency or bandwidth reduction and/or increase in transmission reliability
Inventor: DIRR JOSEF DIPL ING
IPC: H04N7/12
Filed: 1989-02-17
Abstract: In this domain, a frequency or time division multiplexing of channels is currently known. However, substantial expenditure and wide bandwidth are required for this purpose. In the invention, the serially arranged code elements are disposed individually in parallel and are all combined to form a code word. Transmission reliability is achieved by converting the information into PDM pulses and by re-coding these pulses into the cycle durations of half cycles or cycle durations which are then transmitted in an uninterrupted sequence of positive and negative half-cycles.
