Title: Flow channel with radiometric density measurement for flowable media
Inventor: KRETSCHMER HORST DIPL ING
IPC: G01N23/12
Filed: 1987-07-16
Abstract: The invention relates to a flow channel for measuring the density of dust-type and fine-grained solids suspended in a carrier-gas flow in pipelines with high solids concentration, in particular of fuels for gasification and combustion in a reactor. The object of the invention is to measure the density of two-phase media, in particular dust/carrier gas mixtures with high sensitivity, precision and time response, measurement being made possible at relatively high pressures. This results in the task of providing a flow channel which is suitable for radiometric density measurement on flowable fluid media using a ss-radiating source and a specific ss-detector for small pipeline diameters (</= 20 mm). According to the invention, the flow channel is formed by a multi-part internal section whose cross-section has an equal-area transition from circular to rectangular and vice versa. Three bores are situated opposite one another along the axis of the ss-ray source and ss-detector in the housing and in the internal section, and the third bore is offset by 90@.

Patent DE-3736984-A1 (DE)
Inventor: ADAMSON ARTHUR PAUL
IPC: F02C7/32
Filed: 1987-10-31
Abstract: In order to produce a power output at a substantially constant speed, a multi-spool turbine engine is provided, with means for generating power related to a rotational speed difference between the spools. In one version (Fig. 3) spools 18,20 of a multi-spool turbofan engine are connected to two inputs of a differential gear 26. The differential gear's output is connected to drive an alternator 50. In another version (Fig. 7), an alternator's coils (64) are carried on one spool (18) and magnets (62) are carried on another spool (20). An electrical output created by a rotational speed difference between the coils and magnets is taken through a slip ring (68) or by a rotating transformer (Fig. 8). In both versions the alternator rotates at at substantially constant speed to yield a relatively constant frequency output, requiring no transmission/clutch devices, or frequency compensating circuits. The alternator can be replaced with a d.c. generator which can be small because of the generator's constant operating speed. A control system (Fig. 9) may be provided which compares a signal representative of alternator frequency with desired valves stored in a memory 92 a signal from comparator 90 being passed to controller 96 to vary the position of stator vanes 98 in the engine. <IMAGE>

Title: Backflow preventer
Inventor: KESSEL BERNHARD
IPC: E03F7/04
Filed: 1987-11-20
Abstract: The backflow preventers used especially for faeces-containing sewage have a disadvantage, in the event of backflow and solid or textile contaminants enclosed between the closure part (13) and the seat (4) of sealing to only an insufficient extent. The novel backflow preventer is intended to be insensitive to enclosed contaminants and to be sealed at all times in the closed position. In order to be able to ensure the sealing action of the backflow preventer (5) in the closed position at all times, either one or a combination of the following measures are provided:   the sealing body (15) is provided with at least two spaced-apart sealing lips (29, 30) which run around parallel to one another, and the border region (19a, 19'a) of the reinforcing plate (19) is bent off; at least part of the cavity (34) of the sealing body (15) is in connection with a pressure source (41) of a gaseous medium via pressure-controlling means (40); the sealing element (8') on the seat (4) is provided with a hollow chamber (31) which runs around it and is in connection with a pressure source (41) for a gaseous medium via a pressure-controlling means (40).   By virtue of the reliable sealing action in the closed position, the backflow preventer is especially suitable for faeces-containing sewage. <IMAGE>

Title: Connection of tie rods to flanges of articulation or pipe-articulation pieces
Inventor: NONNENMACHER WILFRIED
IPC: F16L51/02
Filed: 1988-06-29
Abstract: In the case of connections of tie rods to flanges of pipe or pipe-articulation pieces, as well as compensators, the tie rods have, up until now, been plugged through the flange by means of their articulation-side end or head. There are application cases in which the head, which usually exhibits a through-passage for receiving a transverse bolt in order to form the articulation, has to be wider, for reasons of strength, than the shaft of the tie rod. In order also to be able to cope with these cases, the invention proposes that the tie rods (12) be plugged, by means of their ends (16) remote from the articulation, through the opening (10) of the flange (6) and have incisions (18, 18a, 40) which are perpendicular with respect to the axis and into which there are plugged transverse parts (20, 30, 44) which rest on the flange (6). <IMAGE>

Title: Sewing machine thread tensioner
Inventor: FISCHER JOCHEN
IPC: D05B47/04
Filed: 1988-12-23
Abstract: In the thread tensioner assembly for a sewing machine, the guide also acts as a receiver for the measured value and as the adjustment unit. The guide mounting can be moved along and back on the direction of thread travel, against a spring when moved in the direction of travel. The measured value is received according to the shift in the guide through the draw tension applied to the thread. A lever holds the guide on an eccentric mounting. The receiver unit for the measured value has a light source and a reflective surface on the lever, with a sensor to take the reflected light beam. In another form, an inductive movement indicator works with a metallic zone on the lever. Or the lever is a projecting arm which, when bent, registers the movement through an expansion measurement strip. The adjustment unit is fixed in relation to the lever, to deliver a setting drive force towards the rotary axis of the lever. The regulator has an indicator for the draw force.
