Title: Heat extraction circuit for waste process water - uses heat pump with cooling stages between steam compressors to reduce corrosion
Inventor: JASTER HEINZ
IPC: F25B1/10
Filed: 1980-04-24
Abstract: The heat pump which extracts heat from water used in an industrial process, passes the wate through a heat extracted steam passed through two compressor stages (20, 21) with a flash cooler (23) between them. This cooler contains water (24) pumped into it from the coil inside the heat exchanger tank. The temperature of the waste water can be 77 deg.C the cold water through the coil being raised from 21 deg.C to 71 deg.C. The extracted steam at 71 deg.C and .035 bar. pressure (absolute) leaves the first compressor at 304 deg.C and 1.75 bar pressure and leaves the flash cooler at 115 deg. C at the same pressure. This cooling action avoids corrosion problems in the circuit. Further cooling stages can be included where further compressor stages are used.

Title: Butt welding mitred thermoplastic frames - in which pressed out weld polymer fills lateral slots to keep outer surfaces clean
Inventor: NARUHUN DIETMAR
IPC: B29C65/78
Filed: 1980-10-21
Abstract: Hollow thermoplastic sections are butt welded together, partic. in making frames for windows, doors, etc. by heating their mitred ends and pressing them together, but so as to prevent the formation of a seam at least in some specific parts. Beneath the top and bottom surfaces which are to be kept clean of any seam, slots are cut across each end, so that, when the ends are welded together at the remainder of the edges, pressed out polymer can flow into the slots; the residual top and bottom of the edges are not heated up to welding temp., and during welding, those parts are only allowed to nearly meet. Method keeps visible working surfaces clean without needing any further processing.

Patent DE-3041788-A1 (DE)
Inventor: TINNES BERNHARD DIPL KFM DIPL
IPC: B22D37/00
Filed: 1980-11-05
Abstract: The hydraulic drive, which has a pump unit, a volume controlling valve and a cylinder-piston unit (11), also comprises a control device with a directional control valve (28) which is arranged downstream of the volume controlling valve (29) and the control piston (30) of which is centred in its centre position by springs (33). Each of the two sides of the control piston (30) is connected via a respective control line (38, 39) to a pilot control valve (21). In order in a simple manner to limit the accelerations of the driven parts and set correspondingly different mass flows in opposite directions of movement, each of the two control lines (38, 39) has two parallel branches, each of which contains a throttle valve (24, 26, 23, 25) and, in series therewith, a non-return valve (27). In each of the two control lines (38, 39), the direction of flow through the non-return valve (27) of one branch is opposite to that through the non-return valve (27) of the other branch. The two pump-side control edges of the main control piston are formed by chamfers (31, 32) which correspond to a predetermined change in the mass flow via each of the two selectable paths. The drive is suitable, for example, for the slide gate nozzle of a Siemens-Martin (open hearth) furnace. <IMAGE>

Title: Sealing tape for pipe screw connections and process for the production thereof
Inventor: KARSTEN WERNER
IPC: C09K3/12
Filed: 1981-04-16
Abstract: Screw-thread sealing tapes of unsintered polytetrafluoroethylene (PTFE) have long been known in the prior art. A sealing tape for pipe screw connections is also already known from Patent Application P 3020157.1 and possesses a non-woven or woven fabric insert which is covered by an unsintered fluoro polymer film on one or both sides. The invention relates to a further improvement of the production process for sealing tapes. In this case the non-woven or woven fabric insert is coated on one or both sides with a paste of unsintered PTFE. The PTFE paste is present in an amount such that, after forcing into the fibre interstices, it also forms a projecting covering of the fibre insert. The coating paste is produced from a mixture of PTFE powder and an aqueous PTFE dispersion, the coating produced from this mixture forming surprisingly water-insensitive coatings of the fibres after processing. To achieve an improved adaptability of the sealing tape according to the invention to the screw thread, the non-woven or woven fabric insert has no fibres or filaments which are fixed with respect to one another. Alternatively, in the case of one-sided coating, the sealing tape may be coated on the side not covered with PTFE paste with a plastic adhesive to improve the adhesion.

Title: Process and apparatus for the filling of containers made of deformable material
Inventor: HAGEN NORBERT
IPC: B65B61/00
Filed: 1981-04-25
Abstract: During the vaccum filling of containers made of deformable material, especially of thermoplastic, those regions of the container which would be inadmissibly deformed as a result of the pressure difference without special precautions are stabilised by retaining devices (28) engaging on the container (10) on the outside. In many instances, it will suffice to use circular retaining devices which resemble suction cups and which, in the projection onto the surface to be stabilised, have a substantially smaller extension than the latter, so that a vaccum filling of containers of this type, also without inadmissible deformation of these, is possible under normal atmospheric pressure in the environment by simple means and at relatively low operating costs.
Patent DE-3116960-A1 (DE)
Title: Tool-changing device
Inventor: REYMANN GOTTFRIED
IPC: B23Q3/155
Filed: 1981-04-29
Abstract: The invention relates to a tool-changing device for cutting machines with heavy tools, which is like a movable carriage with a base frame. Tool-changing devices of the said type are required in particular when the tool to be changed has to be inserted from the side into the cutting machine. In this case, there is gap between tool-changing device and cutting machine. The gap is bridged by track-extension pieces. According to the invention, it is proposed that the base frame (1) of the tool-changing device have a telescopic part (14) which is arranged so as to be movable horizontally in the direction of the cutting machine (28) and back again. Consequently, insertion of the track-extension pieces between the supporting surface of the carriage and the slideways of the cutting machine is unnecessary, and the tool-changing operation can thus be carried out more simply and more quickly. <IMAGE>

Title: Fastening device for a C-shaped clamp
Inventor: WICHERT HANS-RAINER
IPC: E04B9/18
Filed: 1981-06-04
Abstract: The invention relates to a device for fastening a C-shaped clamp, at the ends of which there are provided in each case at least one bearing surface and one receiving channel for a retaining rail which opens in the form of a U towards the clamp and is designed with inwardly angled-off longitudinal edges. C-shaped clamps for the suspension of retaining rails are fastened with so-called quick-clamping suspension means. These quick-clamping suspension means can not be used in every case where retaining rails are used. The object of the invention is to provide a universally usable fastening device for a C-shaped clamp. This is achieved by a spring (2) which is bent in the form of a U and has a longer fastening leg (21) and a shorter receiving leg (22) on which the C-shaped clamp (1) is fastened in a positively locking manner such that, when loaded, the receiving leg has a force component in the direction of the fastening leg. <IMAGE>

Title: Process for the preparation of N-alkylaminomethanediphosphonic acids
Inventor: SOMMER KLAUS PROF DR
IPC: C07F9/6533
Filed: 1981-08-22
Abstract: The preparation of N-alkylaminomethanediphosphonic acids and their N-acyl derivatives takes place in good yields when the products from the reaction, at temperatures of between 40 and 60 DEG C, of acetic anhydride or acetyl chloride with phosphorous acid are reacted, in stoichiometric amounts and at temperatures of between 60 and 90 DEG C, with alkylformamides. Instead of the products of the reaction of acetyl chloride and phosphorous acid, those from phosphorus trichloride and acetic acid can also be reacted. Both monoalkylformamides and dialkylformamides, with the alkyl group being able to carry further substituents such as -NR2, -SH, -OH and -COOH, will participate in this reaction. In addition, the corresponding amines, in particular amino carboxylic acids, together with formic acid and acetic anhydride, can be reacted with the products of the reaction between acetic anhydride and phosphorous acid.
