Inventor: TRENKLER HARRO DR ING
IPC: F23N1/04
Filed: 1979-04-23
Abstract: The system for part-load control of fluidised-bed combustion equipment involves simultaneous variation of combustion air and fuel input and of the quantity of bed material. There is also controlled admixture of flue gas to the combustion air. To permit the admixture a bed material-collector is fitted below this and there is a fuel dispenser above. There is a transfer device linking the two. The heat absorption surfaces within the bed are located between its highest and lowest operating levels. For steam generators, they comprise both evaporating- and superheating-elements respectively, approximately equalling in area the succeeding contact surfaces.

Title: Special extension plate held in extension strips beneath table top - is drawn out without raising table top through upwardly inclined guides
Inventor: HOELSCHER HEINRICH
IPC: A47B1/05
Filed: 1979-09-13
Abstract: The extension plate which can be drawn out without raising the main table top is movably fastened to the extension strips (3) which are attached in two pairs of grooved strips (1) fixed longitudinally to the underside (2) of the table. The bearing points (4) ensure that the extension strips (3) run inclined upwards to the end position of the guide pivots (5) pref. designed as roller pins for easier handling of the extension plate (6). The extension plate lies raised on one side wherein the one-side weight stress causes the support joint (9) to swivel round so that the support point (10) no longer falls back through the weight of the plate. Since the support joints (9) can be provided with connecting strips (11) they can be returned to the original position by suitable pressure on a control button (12).

This edge strip may carry two holding straps, diametrically arranged to the protrusion and of resiliently ductibility design, for retention in holes (15) on the plug housing external latching cams (16).
Patent DE-3001176-A1 (DE)
Title: Concrete covering corrosive salt content monitoring - measuring resistance between bridge reinforcement and bridge road surface
Inventor: LUBER WILLIBALD
IPC: E01D19/08
Filed: 1980-01-15
Abstract: A salt detection method, for salts in concrete coverings of bridge superstructure reinforcement without removing the bridge covering, is applicable to reinforced concrete bridges or similar structures subjected to salt damage. The presence of salts is determined before corrosion of the steel occurs. This is achieved by detecting the presence of salts which have entered from above via a damaged coating into the concrete. The method involves making an electrical resistive measurement through the bituminous bridge coating. One pole of the measurement equipment is connected electrically to the upper reinforcement of the bridge. The other is connected to a surface contact on the bridge road surface. Measurement of the electrical resistance between the two points gives a reliable indication of whether or not excessive quantities of salts are present.

These lugs through holes (4) in the top of the main cap and slide in chimney-type recesses (5) in its wall, and also in notches in the thread on the bottle neck. This sliding movement can be generated by cams (8) on the shoulder of the bottle neck, and protruding into the notches in the thread of the latter. The outer walls of the recesses in the main cap can be slotted from the bottom to halfway up so as to form spring ribs, each with two holes one above the other, engaged by bosses on the lower ends of the lugs.

Title: Seal for pressure cylinder liner - has insert ring with double seal to relieve axial pressure on liner
Inventor: DREXLER PETER
IPC: F16J15/48
Filed: 1980-02-06
Abstract: The seal for a liner for a pressure cylinder has a ring (12) which is inserted into the liner to position against the bottom corner of the liner, where it sits in the base ( 11) of the cylinder bore. The cylinder pressure operates axially and radially on the ring to complete the seal between the liner and the bore without any axial thrust on the liner. The sealing ring (12) has a rectangular profile and with one sealing ring (16) against the liner (10) and another ring (17) against the bottom of the bore. The sealing rings extend over only part of the relevant surface of the ring so that the pressure effect on the seals is enhanced.

Title: Connector for miniature PCB - has conventional connector half along board edge accepting plug-on control modules forming continuous control surface
Inventor: PILLET LOUIS
IPC: H05K7/14
Filed: 1980-04-29
Abstract: The connector consists of several modules (7-12) that fit onto the connector half (5, 6) attached to the end edge of the circuit board (3). The connector half attached to the board is a conventional type of connector.

Title: Lightweight foam esp. polystyrene components esp. for models - re:compacted after foaming to produce denser surface
Inventor: NEUHIERL HERMANN DIPL CHEM DR
IPC: A63H27/18
Filed: 1980-04-30
Abstract: A lightweight foam plastics component, esp. for model aircraft and boats, is produced as follows. The component, after the foaming operation has been completed, is re-compacted with heat thus hardening the structure at the surface to a greater degree than in the interior. In addn., during this recompaction process a shear zone is produced between the upper and lower parts of the mould thus cutting out the component from the surrounding material. Pref., grooves or beadings are formed during the moulding to become subsequent ribs or spars. The method in particular may be used for making, e.g. a wing from an upper and lower part which are subsequently bonded together in the form of two half-shells to produce one complete shell.
Patent DE-3020627-A1 (DE)
Inventor: FLAIG WILLI
IPC: E04B9/14
Filed: 1980-05-30
Abstract: The jointed strip grid ceiling contains joint elements (11) and casing elements (12). The latter are arranged in the form of a grid or lattice and are connected, at their points of intersection, to the joint elements (11). In order that buckling is avoided at the points of connection, in each case a plurality of spaced-apart connecting pieces (17, 19, 20, 21, 22, 23) are provided. The latter are composed of receiving openings with suspension edges (19, 20 or 21, 22) in one element and of projections (17 or 23, respectively), which engage in said openings, on the other element. By bending off a projection (17) and thereby bracing the two elements (11, 12) with respect to each other, a rigid connection which cannot be released unintentionally is formed. <IMAGE>

Title: Circuit for providing audio-frequency energy
Inventor: BOCK DETLEV VON DIPL PHYS DR
IPC: A63H19/24
Filed: 1981-01-21
Abstract: The invention relates to a circuit for providing audio-frequency energy. In the case of model railways, it is normal to supply the lights of the carriages and other loads together with the operating voltage for the locomotive motors via the rails as live and return lines. This results in all the loads being supplied with a variable operating voltage, depending on the desired speed of the locomotives. In order to overcome this disadvantage, the invention proposes a circuit having a square-wave generator and amplifiers which are connected to the power supply, a series-resonant tuned circuit (6), comprising a capacitance (8) and an inductance (7), being arranged in series, according to the invention, with the amplifier output (A1) of the generator circuit for the square wave, which tuned circuit (6) converts the rectangular waveform of the audio-frequency energy into sinusoidal form, essentially without any losses. <IMAGE>
