Title: Appts. for mfg. reinforced components in laser-cured polymer - has laser-curable polymer in bath, laser directed at polymer surface where fibres pass through polymer and are guided relative to laser beam angle
Inventor: KRANZ CURT DR ING
IPC: B29C70/28
Filed: 1991-01-23
Abstract: Appts. is for mfg. plastic components based on polymers cured by a high energy source, e.g. laser. The polymer is held in a container through which a component supporting tray passes vertically downwards as the swivelling laser is directed at the polymer surface. Localised curing of the polymer occurs close to the laser beam and the component is built up in layers as the supporting tray descends vertically through the polymer. Reinforcement is added to the component during the layer building stage by guiding load-bearing fibres through the polymer and at right angles to the fluid surface and holding them at the container base. Guiding elements above the fluid surface move horizontally, pref. in a straight line to enable the fibres within the fluid to always lie in a predetermd. cured zone. USE/ADVANTAGE - The appts. mfrs. components of desired profile using laser-cured polymers and enables reinforced, complex, single-piece shapes to be mfd., thus broadening the area of use of such component

Patent DE-4104573-A1 (DE)
Inventor: WEINMANN KLAUS
IPC: C08G85/00
Filed: 1991-02-14
Abstract: In a process for industrial fractionation of polymers using an extraction column and a homogeneous extraction agent a homogeneous feed is supplied to a region of the extraction column which is nearer the upper end thereof when the feed has a greater density than the extraction agent and which is nearer the lower end thereof when the feed has a lower density than the extraction agent. An apparatus for carrying out this process consists advantageously, instead of a pulsed sieve plate column as hitherto, of an unpulsed filling body column which leads to a better separation because a back mixing is avoided in favourable manner.

Filed: 1991-05-14
Abstract: The application relates to a device for the compounding and extrusion of viscous, elastic, plastic and similar materials having a plurality of screw shafts (2, 3) rotating in a common housing (1). This device is to be designed in such a manner that the resistance to which the material to be processed in the device is subjected can be sensitively controlled without the material being subjected to impermissibly severe stressing. The screw-shaft extruder therefore has an enlarged radial play (8, 9) in the region of the saddle over a relatively large length of the housing, which play is disposed upstream or downstream of the deflection in the region of the saddle acting as a natural throttle. <IMAGE>

IPC: E04G23/02
Filed: 1991-06-19
Abstract: 2.1. In order to repair cracked construction parts, it is known to grout the cracks with synthetic resin injections. Because of the different composition and flow properties of synthetic resins and mineral binders, the injection plugs used for synthetic resins are not suitable for grouting with mineral binders. 2.2. In order to provide an injection plug suitable for grouting with mineral binders, the connection is integrally moulded onto the rear end of the shaft. Furthermore, in order to form a non-return valve, a cap is mounted on the front side of the shaft, the base of which cap has openings disposed concentrically to the centre axis and outside the longitudinal bore of the shaft. <IMAGE>
Patent DE-4120821-A1 (DE)
Inventor: PFEIFFER WOLFGANG PROF DR ING
IPC: G01R23/16
Filed: 1991-06-24
Abstract: A method for measuring partial discharges in a multiplicity of similar devices under test by applying a variable test voltage of a defined wave shape to the respective device under test which is connected in series with a measuring resistor, is to be developed in such a manner that the measurement and evaluation of the partial discharge pulses can be carried out rapidly and with high accuracy. This is achieved by the fact that, for the purpose of automatic comparative measurement, the partial discharge pulse of a device under test is coupled out with a wide band width and is then amplified by a wide band amplifier (22) with input voltage protection (23 a). The amplified signal is supplied, via an antialiasing filter (24), to an analog/digital converter followed by a digital memory, particularly a digital storage oscilloscope (26), and digitally stored after the analog/digital conversion. The stored data corresponding to the partial discharge pulse are then input to a computer (28) and transformed by this computer from the time domain to the frequency domain by Fourier transformation and the calculated digital values are stored. Before the automatic measuring process, the said method steps are carried out on several sample components of the same type as the devices under test to be measured and from these stored transformed data, a partial discharge pulse spectrum typical of the component series is averaged and stored and made available as reference partial discharge pulse spectrum. The test voltage is then applied to a device under test and one or a number of partial discharge pulses are individually coupled out in accordance with the method steps above and are finally transformed. Each measured partial discharge pulse is matched with the amplitude values of the reference partial discharge pulse and compared with it. <IMAGE>
