Patent DE-3000418-A1 (DE)
Inventor: DAHINDEN VINZENZ DIPL CHEM
IPC: H01F41/12
Filed: 1980-01-08
Abstract: For an insulating-material insert between windings of transformers which are not subjected to any pressing in order to form square or rectangular winding cross-sections, a cellulose-fibre paper, for example press board, is subjected to a stamping process in order to produce a rippled or pitted effect or the like in the form of points. Only the peaks of the bulges thus obtained are coated with dissolved epoxy resin, and the material is then dried out until the adhesive is dry to the touch. When used between windings of an electrical apparatus, heating to above at least 110 DEG C is sufficient to cure the epoxy resin and thus to connect the wires of the windings and the insulating material.

Title: Reactor for coal hydrogenation - has countercurrent flow of gas and liq. and baffle plates to give turbulence
Inventor: PEUKERT ERNST DR ING
IPC: C10G47/00
Filed: 1980-04-05
Abstract: In a process for the degradative hydrogenation of coal and heavy oils at temps. of 400-500 deg.C and pressures of 80-700 bar, the arrangement of the reactor is new. A mixt. of e.g. fine-ground coal and hydrogenation catalyst in heavy oil enters the top of a vertical reactor at 80-350 deg.C. The H2-rich gas, initially at 20-250 deg.C travels upwards, counter-current to the liq., entering the reactor a) at its base, and b) through its sides and into the hydrogenation zone. The reactor is provided with perforated horizontal plates in the zones of heat exchange at top and bottom and opt. in the hydrogenation zone between them, so as to cause turbulent mixing of gas and liq. Greater feedstock throughputs are possible for a given reactor vol. Improved mixing permits building of reactors of greater dia. than at present, i.e. up to 3m or more, instead of 1.5m max. This saves capital costs, as does the non-requirement for separate heat exchangers for reactor inlet and exit streams. There are energy savings because complete preheating of feed stream is unnecessary and the heat in the product stream is used optimally.

Title: Indian ink pen
Inventor: RODOUSAKIS ELEFTERIOS ING GRAD
IPC: B43K5/18
Filed: 1981-04-07
Abstract: Indian ink pen for all line widths determined according to DIN 15 and for lettering according to DIN 16 and 17. The problem with all indian ink pens is in particular one of removing the dried indian ink from the writing tube and regulating the pressure in the ink reservoir to ensure continuous drawing. In the case of the novel indian ink pen, dried ink in the tube (7) is removed by force of pressure which is produced by virtue of the fact that the knurled screw (3) is screwed tight and as a result the plunger (4) closes the nozzle of the ink reservoir (1). By unscrewing the knurled screw, as a result of the spring force of the spring (6) the plunger returns into its original position. The pressure in the ink reservoir (1) is controlled by pressing the plunger (4) for a short period (with the ink pen held vertically), as a result of which air flows in and out. <IMAGE>

Title: Control valve
Inventor: GEORGI WOLFGANG
IPC: F16K11/07
Filed: 1981-06-29
Abstract: In the case of a control valve, having a valve piston which can be locked into the individual switching positions and can be automatically returned to the neutral position, provision is to be made to ensure that the permissible pressures are not exceeded and that the control valve is nonetheless reliably returned to the neutral position under a very wide range of operating conditions. This is achieved according to the invention in that a transmitter (7) is arranged in the pump feed pipe (6) leading to the working cylinder (2) and determines whether or not the hydraulic medium is flowing in this feed pipe (6) and triggers the return of the valve piston (1a) to the neutral position if no flow is detected. <IMAGE>
