Title: Current regulator supplying remote load - uses bridging diodes to protect sense resistors from full load voltage in event of load line failure
Inventor: FREYE KLAUS DIETER
IPC: G05F1/571
Filed: 1990-03-21
Abstract: A voltage source (Q) is connected via a controllable rectifier section (SG) and load lines (LL & LL') to the remote load (RL). If a load line fails, bridging diodes (D1 & D2) prevent the full load voltage being developed across either of 2 sensing resistors (R1 & R2) through the sense lines (FL & FL'). Current through the resistors is limited by a positive-temp.-coefft. resistor (PT) or other similar thermal or electronic safety device. USE/ADVANTAGE - Stabilised high-current I.v. source supplying loads requiring close voltage tolerance.

Title: Thermoplastic elastomers mfr. - by mixing classified scrap thermoplastic with natural or synthetic rubber and vulcanising to produce an inter-penetrating network
Inventor: JENTZSCH JOACHIM PROF DR
IPC: C08J11/06
Filed: 1991-01-23
Abstract: A process is claimed for the prodn. of thermoplastic elastomer (TPE) from classified thermoplastic (`TPA III - flotation or polyolefin fraction') (I) consisting of HDPE, LDPE and PP; the process involves mixing (I) in a kneader with natural and/or nitrile rubber in the wt. ratio (50-80):(20-50), the required increase in temp. being produced by the optimum kneader blade speed (n) = 80 r.p.m., and also by addn. of 20-40 pts.wt. reinforcing filler, e.g. carbon black, after which 5 wt.% vulcanising agent or system, e.g., sulphur, is added and the mixt. is vulcanised at 180-200 deg.C. Also claimed is TPE produced by the above process, with a structure formed by an interpenetrating network (IPN). To improve the flow properties and to meet the requirements of specific applications, the TPE is processed by blending with other prim. and sec. thermoplastic polyolefins and by addn. of mineral oil, e.g. in the wt. ratio 80/15/5, in a solid mixer or by appropriate metering, then homogenised under high shear forces in a twin-screw extruder and granulated. USE/ADVANTAGE - The process enables the prodn. of TPE from waste thermoplastics more economically and more rapidly than by direct synthesis; it thus makes it possible to improve the physical-mechanical properties of the scrap material and convert it into prods. with a wide range of applications (e.g. moulded prods. for agricultural or constructional applications subject to high mechanical and thermal load

Title: Increasing measuring precision for FMCW radar - uses auxiliary signal to mix again with differential mixing signal from transmit and reception signals
Inventor: FRANKE MICHAEL
IPC: G01S13/34
Filed: 1991-05-03
Abstract: The measuring precision of an FMCW radar for location of reflection in optical fibres (LWL) is increased by forming differential frequency of a mixing signal (fM) from transmit and reception signal. The mixed signal is mixed again with a triggered auxiliary signal (fH) with tunable frequency. One of the side bands, generated by the mixing, is spectrally analysed. In addition the instantaneous value of the auxiliary signal frequency is used also for signal evaluation. The evaluation interval in the spectral analysis is linked with a rigid phase to the ramp signal (fR), used for the control of the transmit signal frequency. ADVANTAGE - Facility for forming integral ratio of mixing signal frequency to ramp frequency for each reflection.

Title: Improved silicon yield from redn. of quartz by carbon@ - uses preforms of fine grained quartz with carbon@ medium and small quantity of carbide forming elements present silicate(s)
Inventor: LASK GERT-WILHELM DR
IPC: F27B1/09
Filed: 1991-08-08
Abstract: The process of Si formation by redn. of quartz by carbon in an electro-oven uses preforms of the raw materials fine grained quartz sand and fine grained carbon medium as well as pieces of quartz. The process, which occurs in two parts, forms SiC from quartz in reaction with open pored coke and a second part in which SiC reduces quartz in the lower part of the furnace. Gaseous Si-monoxide, which rises in the furnace, is reduced to Si by the action of the carbides of additives present in the preforms. This occurs pref. at a temp. below the m.pt. of the silicates, under the formation of CO, resulting in increased process yield by at least 5 wt.%, pref. 10-20 wt.%. The carbide forming agents are pref. silicates of at least one of the elements Mg, Ca, Al. The preforms used pref. consist of a mixt. of fine grained quartz sand, pref. fine grained non-caking carbon medium, pref. oil-derived pitch or a mixt. of pitch with coal. The mixt. is formed into briquettes containing a higher C-content than the stoichiometric quantit
