Patent DE-3907637-A1 (DE)
Title: Rodless drilling, pressure or cleaning implement
Inventor: TUTTASS EDMOND ING GRAD
IPC: E21B4/14
Filed: 1989-03-09
Abstract: If alternately inflowing and outflowing pressure water or a pressure fluid rushes into a hole or pipe, a rodless drilling, pressure or cleaning implement is used there which has a gas accumulator which, during alternating hydraulic pressure by pressurising and expanding the gas pressure cushion and the volumetric change associated with this, sets the working fluid in the hole or pipe in an oscillating alternating flow. A portion of the hydraulic pressure energy of this flow drives the tool and/or other devices via a hydraulic drive. A pump produces the necessary hydraulic work and the working pressure outside the hole or the pipe. A reversing device takes care of the alternating pressure delivery. Additional pressure blows on the tool are obtained by in each case sudden braking of the fluid column at the hydraulic drive. With the implement, holes up to several kilometres in length can be driven as pipelines or as pressure holes into coal seams for underground coal gasification, pipelines can be cleaned and water and other materials, e.g. for disposal or for terrestial-heat extraction, can be injected to great depths. Bores, even deep or superdeep bores, can be produced exceptionally quickly and cost-effectively with this implement for little outlay. During the discharge of the cuttings, the flow in each case leading downwards or upwards is ... through a thin-walled tube, through a thin-walled dividing wall, e.g. a sheet, or through ...

Title: Underfloor railway wheel turning system - involves integration of NC turning, wheel inspection and measurement, vehicle handling and computerised optimisation
Inventor: SCHOENHUBER MAX-JOSEF DR ING
IPC: B23B5/32
Filed: 1989-06-19
Abstract: The integrated system is for reconditioning railway wheel sets.  It consists of an underfloor CNC lathe, inspection and measuring equipment, vehicle lifting and positioning equipment and optimising computers for tool path and work sequence computations. Increased demands of train speed, passenger comfort and safety have meant that an axle by axle approach to wheel turning and reprofiling is no longer adequate.  Smaller tolerances specified on a per vehicle basis require a three-stage process of inspection and measurement survey, computerised optimisation of the cutting process over all axles, and profile machining according to an optimum sequence of vehicle movements. USE/ADVANTAGE - Railway wheel reprofiling to closer per-vehicle tolerances.  Material and time savings are achieved and wheel profiles are optimised for high-speed trains.

Title: Device for recovering energy in reverse osmosis systems - uses throttle valve in retentate line replace by pump coupled to feed pump with smaller delivery rate
Inventor: POLASCHEGG HANS-DIETRICH DR
IPC: B01D61/06
Filed: 1989-12-13
Abstract: Device for recovering energy in reverse-osmosis installations comprises first pump (1a) in the raw water inlet pipe, which is mechanically connected to a second pump (1b), which is in the retentate pipeline (i.e. the return pipe for water which has not passed through the osmosis membrane), and has a delivery rate which is less than that of the first pump (1a). The delivery rate of the second pump is 60-90 percent of that of the first pump.  The two pumps (1a,1b) may be in the same housing and may be multiple gear pumps whose driven wheels engage with driving wheels on a single drive shaft. USE/ADVANTAGE - Used in reverse osmosis systems in e.g.  desalination of sea-water. The customary throttle valve used in the retentate line is replaced by the second pump, so energy normally dissipated in the throttle valve is in part recovered and the overall energy consumption of the installation is therefore reduced.

Title: Treating eutrophic stagnant surface water - by covering the sediment with a semipermeable film to encapsulate pptd. phosphate
Inventor: PETERSEN FRED DIPL ING
IPC: C02F3/12
Filed: 1990-01-25
Abstract: Process for restoring stagnant eutrophic surface water by covering the sediment with a gas-permeable film or membrane which is water-impermeable in the direction from the sediment to the body of water, e.g. where the covering layer is of GORE-TEX (RTM). The semi-permeable film layer may be covered with a gas- and liq.-permeable felt followed by a stabilising layer of sand, gravel, heavy slag or other material with a low nutrient content and esp. an Fe-contg. material. USE/ADVANTAGE - The layer of semi-permeable film prevents the phosphate present in the sediment from re-dissolving in the body of water and gives a progressive mineralisation of the phosphate in the sediment, esp. in the presence of Fe which promotes formation of Fe(III) phosphate. Pref. the eutrophic water is treated in spring or autumn by addn. of a precipitating agent for the phosphate, if possible with supplementary aeration, and the phosphate is encapsulated in the resulting sediment by covering the sediment with the semipermeable film layer.
Patent DE-4006264-A1 (DE)
Inventor: KRAEMER WENDELIN DR
IPC: G21C3/322
Filed: 1990-02-28
Abstract: In a boiling water reactor, a secondary flow channel is formed inside the jacket of a fuel element by four fuel rods parallel to the jacket walls. At least two, preferably four blades, tapered in the direction of flow of the coolant and bent in such a way that they generate a swirl in the vertical coolant flow, are arranged in the secondary flow channels. It is thus possible to obtain a relatively high output from the fuel element.

Title: Controlling functions in complex serial data transmission networks - buffering input data for checking against diagnostic information and correction by program-controlled transfer
Inventor: HELLING THOMAS DIPL ING
IPC: H04L12/26
Filed: 1990-11-28
Abstract: Data from an incoming line (DAI) are stored in a first shift register (SR16) and compared (VG16) with information from a program register (REG16). If euqality is found, an interrupt command (INT) is generated and the variable part of the information is transmitted to a first part register (REG8/1). A microprocessor forwards modified information to a second part register (REG8/2) for transmission from a second shift register (SR8) to an outgoing line (DAO). If a time limit is exceeded, the input is transmitted without modification. ADVANTAGE - Protocol tests for fault simulation in extensive networks can be performed at less cost.

Patent DE-4120352-A1 (DE)
Inventor: RUTHARDT SIEGFRIED DIPL ING
IPC: F02D1/02
Filed: 1991-06-19
Abstract: In centrifugally-controlled total rotation speed regulators which control the full-load charge of the appropriate fuel injection pump in accordance with the charge pressure, the hot-starting charge is to be reduced at higher engine operating temperatures to prevent sudden smoke emission. To this end, besides a basic support (26), the rotation speed regulator has a supplementary support (28) which is fitted to rotate on the basic support (26) and to pivot between two setting stops (31, 32). In addition to a full-load stop (27) on the basic support (26), the supplementary support (28) has an additional stop (33) which can be moved transversely to the direction of rotation of the basic support (26) by a matching unit (41) in accordance with the charge pressure. The setting stop (31) takes the form of a temperature-controlled adjuster (31). It positions the additional stop (33) in such a way that a sensor (39), the position of which determines the richness of the fuel mixture, moves the additional stop (33) out of the detection range of the sensor (39) when the internal combustion engine is running at low temperature and thus provides for the necessary rich fuel mixture, whereas with the engine hot, when it is started the additional stop (33) pivots into the detection range of the sensor (39), thus limiting the richness of the fuel mixture and preventing the sudden emission of smoke on hot-starting.
