Title: Apparatus for the winding of fabric webs
Inventor: SCHMIDT SIEGFRIED
IPC: B65H19/28
Filed: 1989-01-11
Abstract: The apparatus possesses a guide head (1) which, for applying the fabric web to the winding shaft (2, 2'), has a guide gap (4), through which the fabric web runs vertically, and which is adjustable transversely relative to the winding shaft on a machine frame. Mounted on the guide head (1) are pivoting arms (7) which carry rotating pressure bands (8) and which are adjustable relative to the winding shaft about pivot axes (7'), in the position (Y) swung to against the winding shaft the pressure bands being pressed against the winding shaft (2, 2'), and in their position (X) swung away from the winding shaft the pivoting arms, together with the pressure bands, being located outside the region of the roll forming on the winding shaft. The pressure bands (8) rotate endlessly via deflecting rollers (10, 10.1, 10.2) mounted on the pivoting arms (7) and, in the position of the pivoting arms (7) swung to against the winding shaft (2, 2'), loop round the circumferential surface of the winding shaft (2, 2') with the same direction of rotation. In the winding position of the guide head (1), in which it is located above the winding shaft (2, 2') and the vertical guide plane (5) passing through its guide gap (4) approximately touches the winding shaft on the shaft side having a downwardly directed circumferential speed, one of the deflecting rollers (10.1) is located on the side of the guide plane (5) opposite the winding shaft and the pressure bands (8) run from this deflecting roller (10.1) to the underside of the winding shaft (2, 2'), so that these parts (8') of the...

Title: Plug-in socket seal which is concreted into a pipe socket
Inventor: MUECHER HORST ADOLF
IPC: E03F3/04
Filed: 1989-01-13
Abstract: In order to produce a plug-in socket seal which is concreted into a pipe socket (13), use is made of a sealing element (11) which comprises an elastic sealing ring (1) and a shuttering collar (4) which reaches as far as the outer face of the socket. Said shuttering collar (4) serves as radially outer delimitation of the deformation and assembly clearance (14) located between sealing ring (1) and outer face of the socket. According to the invention, the shuttering collar (4) of the sealing element (11) consists of a material which is less elastic than the material of the sealing ring (1), preferably of a largely flexurally rigid or stiff material. Consequently, the arrangement of additional radial supporting elements in the clearance (14) can be dispensed with, as a result of which material is saved. An undesired deformation of the shuttering collar (4) during the manufacturing procedure of the concrete pipe, and a resulting disadvantageous reduction in the clearance (14), are ruled out, in the case of the shuttering collar (4) according to the invention, due to material hardness. <IMAGE>

Patent DE-3910596-A1 (DE)
Title: Process for preparing dyes of the dibenzopyrenequinone series
Inventor: STEUERNAGEL HANS DR
IPC: C09B3/52
Filed: 1989-04-01
Abstract: In the production of dibenzopyrenequinone vat dyes on the basis of 1,5-dibenzoylnaphthalene, it is sometimes found in practice that the oxidative ring closure step is for no discernible reason much too slow or even incomplete, which leads to lower yield and quality (hue, strength) in the end product. It has now been found, according to the invention, that the addition of catalytic amounts of iron(III) chloride can markedly shorten the time required for the oxidative ring closure of 1,5-dibenzoylnaphthalene, giving the final dye in almost quantitative yield and good quality.

Patent DE-3938786-A1 (DE)
Inventor: KUENDIG KARL DIPL ING
IPC: F23D11/40
Filed: 1989-11-23
Abstract: In a burner (1) for the combustion of liquid or gaseous fuels, its atomising nozzle (12) extends through a screen (21) and is arranged behind the screen (21) in the direction of flow of the combustion air. Furthermore, the atomising nozzle (12) is surrounded by a mixing member (31) which, with the nozzle and/or its casing (25), forms a mixing chamber (32) which is connected to the boiler space (4) via one or more ducts (33). By means of this design, it is possible to add a great quantity of waste gas in a defined controlled manner to the combustion air before the latter flows into the combustion chamber (20), so that a blue-burning soot-free flame with a low content of nitrogen oxides can be achieved. The waste gas is in this connection drawn into the mixing chamber (32) by the combustion air, which flows at high speed, and intimately mixed there, and a virtually stoichiometric combustion at a low temperature level is consequently guaranteed. <IMAGE>

Title: Oxygen@ removal from alkaline cyanide soln. contg. noble metal - using oxygen binder and opt. heavy metal catalyst, reducing zinc@ consumption in cementation
Inventor: DIEHL MANFRED DR
IPC: C22B11/08
Filed: 1990-09-06
Abstract: Removal of O2 from cyanide lixiviation soln. contg. noble metal before noble metal cementation with Zn involves reducing dissolved O2 at pH 9-14 by adding 1-5 times the stoichiometric amt. of O2 binder (I) for quantitative redn. of O2 and, if necessary, an effective amt. of heavy metal catalyst (II) to an O2 content of under 1 ppm. Pref. (I) is a soluble sulphite, whilst (II) is Mn, Fe, Co, Ni or Cu ions, pref. in a concn. of at least 20, esp. 25-100 ppm, partic. Cu ions from a Cu(II) salt in a concn. of at least 25, pref. 25-100, esp. 50-100 ppm. In this case, removal of O2 is carried out at pH 10-12.

Title: Conveyor motion control for casting moulds on pallets - has electromagnetic couplings to control conveyor wheels in relation to sensed position of pallets
Inventor: MORTENSEN ANDERS
IPC: B22D33/00
Filed: 1990-10-29
Abstract: Conveyor for intermittent advancement of moulds (4) on pallets (15) which are shorter than the moulds has the novelty that there is continuous and automatic adjustment of the advancement in the longitudinal direction of the conveyor.  This is effected by having the difference between the drive force and braking force adjustable such that the length of the time interval and/or the resulting force is adjusted depending on the determined position of the pallets in relation to a fixed point. The conveyor has pairs of wheels (18,16,19) of which individual pairs (18,19) have friction layers (20,21) at the inlet and outlet of the conveyor so as to brake the pallets rolling on the wheels. These wheel pairs (18,19) are coupled with a continuously running motor (9) via a drive and an infinitely adjustable electromagnetic coupling or brake (8). The control current for the coupling is generated by a control unit in reaction to a measurement signal whose value corresponds to the sensed position of the pallet relative to a fixed point. The signal is produced by two position sensors (6) sepd. from one another by a certain distance in the direction of advancement of the moulds. USE/ADVANTAGE - The transport system is used in continuous casting installations where the moulds when cast may be  heavy, e.g. around 40 tonnes, and precise, controlled positioning is required.
