Patent DE-3316010-A1 (DE)
Title: Method for monitoring an essentially closed space
Inventor: KOLB HANS DR
IPC: G08B13/183
Filed: 1983-05-03
Abstract: The method is used for protecting spaces, including the internal spaces of motor vehicles, against theft. When persons penetrate into the space, an alarm is triggered. For this purpose, a strong infrared radiation is radiated into the space by means of a transmitter and the radiation arriving at a receiver in the rest state is measured. From this radiation, a reference value is formed. If the incoming radiation deviates from the reference value, for example when a thief penetrates, the alarm is triggered. Continuous deviations of the incoming radiation from the reference value, for example due to irradiation from the sun, lead to a new reference value being formed. This eliminates false alarms.

Patent DE-3326103-A1 (DE)
Inventor: WILDEN OTTO
IPC: E01B25/24
Filed: 1983-07-20
Abstract: Articulated butt joint for suspended rails of a monorail suspended railway, wherein the connection between the lower flanges is deformable as to be horizontal and vertical transverse forces and wherein the connection between the upper flanges absorbs the horizontal and vertical transverse forces. The aim of the present invention is to provide a butt joint which is more appropriate to withstand the transverse forces generated by the vehicle weight and to further reduce to the minimum the inevitable impact forces upon overrunning the expansion gap, as well as their negative consequences. To this effect, the present invention proposes that the linking elements (5) between the upper flanges be comprised of suspension metal plates (10) secured to the upper flanges, overlapping each other in the longitudinal direction of the rails and provided in the overlapping area with longitudinal holes (11) covering each other and tapered as an arc of a circle and intended to receive a suspension bolt (12), the medial point (13) being located in the middle of the expansion gap and at the height of the rolling surfaces on the upper side of the lower flange.
Patent DE-3330276-A1 (DE)
Title: Beer liqueur and its formulation and production
Inventor: SCHIMMEL RONALD
IPC: C12G3/04
Filed: 1983-08-22
Abstract: As statistics show, the consumption of strong spirits is decreasing, whereas the turnover of liqueurs and similar drinks is increasing. A liqueur, such as we intend to produced, can be justified as beneficial from the health aspect, since after all it contains as ingredients beer made according to the purity law, pure sugar and the flavouring vanilla. The beer liqueur can be highly recommended after a meal, since the sugar ingredient also has a positive effect on the blood sugar level after eating. A further reason for the production of the beer liqueur is that the beer liqueur is highly acceptable as an accompanying drink to beer, is readily digestible and is to be preferred to stronger accompanying drinks.

Title: Device for applying an adhesive tape in a U-shaped manner around the edge of a sheet metal moulding
Inventor: SEDLMAYER HELMUT DIPL ING
IPC: B29C63/00
Filed: 1984-04-06
Abstract: The invention describes a device for applying an adhesive tape in a U-shaped manner around the edge of a sheet metal moulding in which it is essential that pressing rollers (22, 23), a pre-folding roller (26) and a guide part (16) are arranged in a single head (1) which is arranged as a whole so as to be pivotable about a supporting axle (4). The axle (4) intersects the axis of rotation of the pre-folding roller vertically and at the same time is aligned so as to be parallel to the axles of the pressing roller (22, 23). Pre-folding roller (26) and pressing roller (22, 23) are arranged directly succeeding one another, the pre-folding part (16) being mounted upstream of the pre-folding roller (26). In addition, the guide part (16), viewed in the axial direction of the pre-folding roller (26), is in each case fitted with a limiting (guiding) collar (39). The device according to the invention has the advantage that the pre-folding roller and the pressing rollers have the least possible distance from one another and that, when a curved sheet metal moulding is passing through the pressing rollers, are deflected about a pivot axis which intersects the axis of the pre-folding roller so that the operating point of the device falls on the pre-folding roller. By this means an especially precise mode of application and an advantageous use of the device in automatic systems are possible. <IMAGE>

Title: Method for producing a flexible tube with the lateral addition of a branch flexible tube
Inventor: GIELER JOACHIM
IPC: B29C65/00
Filed: 1984-04-17
Abstract: The known methods for producing flexible pipes with lateral branches are based without exception, insofar as they do not necessitate metal fittings, on incorporation of a hole into the wall of the main flexible tube and insertion of the lateral flexible tube into the said hole and connection of the lateral flexible tube to the main flexible tube in various ways. Despite additional textile coverings, the mechanical strength of the connections formed in such a way is questionable when the flexible pipes are used. According to the invention, the main flexible tube is completely severed at the point of connection, in order to accommodate a prefabricated connecting piece which permits the reliable mounting of the lateral flexible tube in a kind of socket. This innovative connection can be produced quickly and easily and it satisfies the most demanding requirements.
Patent DE-3417302-A1 (DE)
Title: Circuit arrangement for implementing electrically controllable two-pole or four-pole networks
Inventor: RALL BERNHARD DIPL ING
IPC: H03H11/46
Filed: 1984-05-10
Abstract: A circuit arrangement is proposed for implementing electrically controllable two-pole or four-pole networks using current-controlled power sources (so-called amplifier cells) having a first input stage for current/voltage conversion, a second input stage for voltage/current conversion and gain control, and having a power source output stage, in which only one power source output stage is provided per network node of the two-pole or four-pole networks, and in which as many second input stages are connected to the input of each power source output stage as there are different control currents. In consequence, a considerable space saving is achieved in the integration of the circuit on a semiconductor chip.
Patent DE-3418815-A1 (DE)
Title: Tool, having a wear-resistant layer, for machining metallic and non-metallic materials
Inventor: DIETRICH RAINER DIPL ING
IPC: B23D61/02
Filed: 1984-05-21
Abstract: Tools which are used for machining non-metallic materials, in particular stone, are subject not only to wear on their active machining edges and faces which is caused by the actual machining process of the stone, but also to wear on the passive tool flanks and sides which are not in contact with the stone, but only with cooling lubricants. This wear of passive subjected to the flow of tool flanks which is based on the effects of erosion, cavitation and corrosion and which substantially reduces the service life of costly machining tools is to be eliminated. It is therefore proposed to form the wear-resistant layer, which at least partly surrounds the basic body of such a tool, from a soft material, with the result that the disadvantageous effect of the processes causing the material removal or wear is eliminated by way of energy absorption or particle reflection. <IMAGE>

Title: Arrangement for recording papillary formations of the finger
Inventor: RUELL HARTWIG DR
IPC: A61B5/1172
Filed: 1984-06-28
Abstract: For recording papillary formations of the finger it is known to place the finger on a transparent plate, which may consist of an elastomer, or a similar support which is illuminated from below and to record it from below using a flying-spot scanner or a camera. The known arrangements have the disadvantage that only the part of the papillary formations in contact with the support is recorded. It is intended with the novel recording arrangement to be able to record the papillary formations completely from nail bed to nail bed. For this purpose, a row of contact sensors (BD1, BD2 ...) is fitted on the edge of the support (AP1) on which the finger (FG) rests when rolling about its longitudinal axis. Each sensor on which the finger rests emits a write signal for the cells of a memory (SP1), in which cells the image signals from points assigned to the contact sensor are stored. The field of application of the invention is the sensing and storing of fingerprints. <IMAGE>
