Patent DE-3623161-A1 (DE)
Title: Device for producing flanges on pipe pieces coated internally with plastic
Inventor: MATTHIAE SIEGFRIED
IPC: B29C63/34
Filed: 1986-07-10
Abstract: The invention relates to the processing or working of pipes coated internally with thermoplastic for installation purposes. The aim of the invention is principally a reduction in the relative working time expenditure and the production of flanges, meeting requirements, on pipe pieces, even in length ranges hitherto not workable. The object of the invention is to produce the required flanges on both pipe-piece ends simultaneously in one operation and to make the pipe-piece lengths processable independently of the effect of the device. The device includes two mould heads 1 and a flexible contraction element 6 with a larger diameter than the clear diameter of the pipe piece 3 coated internally with plastic. The contraction element 6 has a tapered end to which a continuation 7 is connected so that the latter can be drawn into the pipe piece 3 provided with the mould heads 1. The contraction element 6 and continuation 7 are each longer than the pipe piece 3. The entire interior coating is made flowable by heating. The contraction element 6 expands radially by virtue of its recovery capacity and displaces coating material into the moulds 4 of the mould heads 1. <IMAGE>
Patent DE-3623280-A1 (DE)
Title: Connecting device
Inventor: MARKER HANNES
IPC: B63B35/79
Filed: 1986-07-10
Abstract: The present invention relates to a connecting device having a coupling part for connecting the mast of a sailboard to the boom. The previously known devices of such type can be applied to the outside of the mast. This is attended by various disadvantages. However, these devices are particularly inexpedient when sails having narrow mast pockets (sleeves) are used. The connecting device according to the invention meets the demands imposed by the boardsailor, due to the fact that the coupling part (4) has at the end connected to the mast at least one retaining element which forms part of a connection resembling a bayonet joint, and that the guiding and securing part of this connection is provided in the mast (1) (Fig. 4). <IMAGE>

Title: Hollow probe for irrigation of the digestive tract of the human or animal body, especially for irrigation of the stomach
Inventor: FRIMBERGER ECKHART DR
IPC: A61M3/02
Filed: 1986-07-18
Abstract: In a hollow probe (1) for irrigation of the digestive tract of the human or animal body, especially for irrigation of the stomach, through the inner duct (10) delimited by the pipe of the hollow probe (1) continuous irrigation is to be facilitated while avoiding any significant increase in the outer cross-section and any reduction of the inner cross-section of the hollow probe. This is achieved in that an outer duct (20) of a thin material is arranged so as to rest tightly against the outside of the pipe (2) and has an opening (9, 16; 40) in the region of the insertion end (4) and in the extracorporeal region (5) and widens to a flow cross-section when the irrigation liquid flows through it. <IMAGE>
Patent DE-3629434-A1 (DE)
Inventor: BRANDENBURG KARLHEINZ DIPL ING
IPC: H03M7/00
Filed: 1986-08-29
Abstract: A digital coding process for transmitting and/or storing acoustic signals, in particular musical signals, in which N pick-up values of the acoustic signal are transformed into M spectral coefficients. The process is characterised by the fact that in a first stage the M spectral coefficients are quantified. After coding, an optimal coder checks the number of bits necessary for reproduction. If the number of bits is above a predetermined number, the quantification and coding are repeated in further stages until the number of bits necessary for reproduction no longer exceeds the predetermined number of bits. The required quantification stage is transmitted or stored in addition to the data bits. The advantage of the process is that acoustic signals in particular musical signals, can be transmitted and/or recorded without any subjective quality reduction of the musical signals with a reduction of data rate by factors of 4 to 6.

Title: Interior corner for shutterings
Inventor: SCHLIEPHACKE HEINRICH DIPL ING
IPC: E04G17/00
Filed: 1986-11-18
Abstract: The invention discloses an interior corner for shutterings, which exhibits two shuttering panels which are arranged at an angle with respect to one another on a split frame, the frame containing, in the vertex or corner region, a spring element which permits the angle between the two shuttering panels to change. In order to eliminate the movability and adjustability of the two shuttering panels relative to one another when providing shuttering and during the duration of concreting, but, on the other hand, to be able to utilise said movability and adjustability when removing the shuttering, the two parts of the frame are held together by means of a butt strap which can set and hold the two frame parts at a fixed distance.

Title: Method of fabricating high-speed semiconductors
Inventor: PROTOP CORNELIU DIPL PHYS
IPC: H01L21/263
Filed: 1986-11-21
Abstract: To reduce the reverse regeneration time (Tq) without substantially increasing the breakdown voltage drop (UD), the semiconductors are irradiated with fast neutrons and gamma quanta and then thermally treated. The semiconductors are irradiated in large quantities as doped and metallised chips or as components incorporated in packages. The optimum neutron fluence for the irradiation of a planned semiconductor type is determined on the basis of determining the dependence of  DELTA Tq/ DELTA F, Tq and UD on the fluence F in the interval 5 . 10<10> - 5 . 10<12> of fast neutrons/cm<2>. The irradiation is carried out in air at room temperature or higher temperatures. The radioactivity induced in the semiconductor by neutron and gamma irradiation is very low. To produce as low as possible an activity level, measures for reducing the thermal neutron fluence are proposed. A few days of simple storage (radioactive cooling) of the irradiated semiconductors brings the induced radioactivity level far below the natural level.

Title: Process for producing a seal from microporous polytetrafluoroethylene
Inventor: TISCH WERNER L
IPC: B29C48/03
Filed: 1987-02-02
Abstract: A seal of polytetrafluoroethylene is produced by extruding the starting material to form a profile of preferably rectangular cross-section, stretching the profile thus obtained and prepressing it (transversely to the longitudinal axis). To increase the dimensional stability and to improve further properties of the seal, the prepressed profile is sintered, that is to say subjected to a heat treatment. In the sintering there is a longitudinal shrinkage of the profile strand by approximately 50%. At the same time, the density increases by more than a factor of 2, whereas, with approximately uniform width, the height of the sealing profile increases slightly with respect to the prepressed state. The final sealing profile can be used for a wide variety of purposes. The seal has a better dimensional stability than the non-sintered seal, it remains flexible and can easily be rolled onto reels.
Patent DE-3703537-A1 (DE)
Title: Combined junction box and double-hook installation device for luminaires
Inventor: FISCHER HEINZ
IPC: F21V21/03
Filed: 1987-02-06
Abstract: The invention concerns the safety-related perfection of heretofore "loose" grid outlets for ceiling luminaires by means of "FESTE" (fixed) socket installations, and thereby easier handling and prevention of accidents to lay persons/consumer protection when installing and removing luminaires, including the loss of equilibrium/toppling of ladders which can be avoided by single-handed actuating of plugs. It consists of two suspension hooks, a junction box for receiving an electrical connection unit (for plug coupling or rotatory coupling) which can be fixedly inserted into the junction box, and, for the hooks, sockets which are spatially assigned to the junction box in an unambiguous manner or materially connected to it. The junction box is designed in such a manner that it envelops, by means of sealing areas and gap-less sealing rings, the space which receives the cable ends of the electrical lines, and does so in a water-tight and gas-tight manner. The hooks are fixed in the sockets with their shank base in an articulated manner such that they are suspended mutually opposite each other in a mirror-inverted manner and that their pivoting region is limited by stops. The shank of the hooks is straight or bent, both hooks are hooked into the suspension eye of the luminaire one after the other, and subsequently the luminaire suspension is centrally held at a moderate distance above the junction box. <IMAGE>

Title: Process for removing pollutants from flue gases and apparatus for carrying out the process
Inventor: NOETH GEBHARD
IPC: B01D53/50
Filed: 1987-05-18
Abstract: In a process for removing pollutants from the flue gases of furnaces, cooled flue gases and condensates can be reacted with neutralising substances, in which case they are previously conducted in the inflow over neutralising substances, such as magnesite- and dolomite-containing granular fixed bed filters. To improve this process, it is proposed that further heat is allowed to be given off from the flue gases in the inflow to the fixed bed filters and housing walls and that an additional process water circulation, with the aid of pump and spray elements, flushes and wets the surfaces of the granules of the fixed bed filter, so that, in addition to solids, the pollutants crossing into the neutralisation process at the wet surfaces also pass in part into the water circulation and are oxidised therein, in which case they pass through at least one further filter system within the circulation, in which pollutants and neutralisation products are removed from the circulation both by reactions and by flocculating out. <IMAGE>
Patent DE-3722627-A1 (DE)
Inventor: FASTERDING GUENTER DIPL ING
IPC: E01B3/16
Filed: 1987-07-09
Abstract: It is proposed to arrange crossbars (24) consisting of right-angled profiles in the ballast bed under steel sleepers (3) for railway tracks, the first flange of which profiles is welded with the base of the sleeper and the second flange of which projects perpendicular away from the base deep into the ballast bed. As a result, the lateral forces which occur on the passage of a train are absorbed by the rails and sleepers and a transverse displacement of the sleepers and of the entire track is prevented. For an optimum design of the crossbars, they can be used as a stacking aid during the transport of the steel sleepers which have been preassembled ready for laying at the manufacturer's, so that shipping timbers can be discarded. <IMAGE>

Title: Device for heat treatment of material webs, in particular textile webs
Inventor: GLAESER DIETER DIPL ING
IPC: F26B13/02
Filed: 1987-08-19
Abstract: The invention relates to a device for heat treatment of material webs, in particular textile webs, with a gaseous treatment medium, e.g. a tentering, drying and fixing machine. The object of the invention is to improve the ratio of the width of the device to the width of the material web treated. The aim of the invention is to design flaps, which serve to close bypass openings which make possible the surrounding of the nozzle boxes by the treatment medium, in such a manner that the depth of the pressure boxes arranged between blowers and nozzle boxes can be significantly reduced without a reduction in the treatment quality. According to the invention, this aim is achieved by the pivot axis of the at least one flap being further away from the blower than the outlet opening closest thereto of the nozzle surface of the respective nozzle box. <IMAGE>
Patent DE-3727931-A1 (DE)
Title: Seal
Inventor: GIESEN FRANZ-JOSEF
IPC: C09K3/10
Filed: 1987-08-21
Abstract: A full-area or part-area coating applied to the sealing surfaces of seals able to withstand static loading, for internal-combustion engines in particular, is produced from a polymer mixture which cures rapidly at room temperature and comprises a plastic which is used in commercially available, quick-drying adhesives, and a micronised aluminium powder as filler. The coating is not tacky, it has good sealing properties by virtue of pressing plastically against the sealing surfaces to be sealed and has universally good adhesion on the widest variety of sealing materials. Due to the quick drying at room temperature, the polymer mixture is easy to handle and can be used cost-effectively both in mass production and directly before installation without sizable installations or considerable energy costs.

Title: Abutment which can be positioned in masonrywork
Inventor: QUANTE HEINRICH
IPC: E04B1/00
Filed: 1988-01-23
Abstract: In order to channel in loads on facades or other regions of structures, use is made of an abutment which is provided, in particular, for masonry walls. Said abutment is effectively braced in the bore which has been introduced into the masonrywork beforehand, the expansion element influenced by the ring bracing segments and the clamping bolts being configured as a neoprene casing which is closed all the way around and between which and the basic body the ring bracing segments are arranged with clamping bolts running between them. Specific introduction of pressure takes place, in this arrangement, by corresponding thickening of the neoprene casing or by assigning a further outer casing and/or changing the ring bracing segments and/or the clamping bolts, the widening taking place in each case towards the load-bearing region of the masonrywork. This makes it possible to allow the introduction of pressure to take place in precisely that location where the masonrywork, by virtue of the corresponding design, is also best suited for this purpose. <IMAGE>
