Patent DE-3206180-A1 (DE)
Title: Process for the production of a preform from which optical fibres can be drawn
Inventor: JOSTAN JOSEF L DR RER NAT
IPC: C03C13/04
Filed: 1982-02-20
Abstract: For a process for the production of a preform from which a highly accurate optical fibre which has a length of several kilometres can be drawn inexpensively and in which process, for the production of the preform, at least one glass-forming layer is deposited on the outer surface of a cylindrical starting element which is rotating about its longitudinal axis, it is proposed that the cylindrical starting element used is a high-purity quartz glass to which several layers of the later core glass material of the fibre are applied one after the other by a thermal spraying process, in particular by a plasma spraying process. In the spraying process, pulverulent starting materials for the layer to be applied are to be admixed with the carrier gas. The glass fibre is subsequently obtained by invaginating a heated tube end and drawing the glass fibre through the inside of the tube. In the embodiment which proposes that the starting element comprises an easily removable material and that, in addition to the core glass material, also the cladding glass material of the fibre is applied to the starting element, the glass fibre can be drawn directly (without invagination).

Title: Gate valve for gas lines in particular
Inventor: MUELLERS JOSEF
IPC: F16K31/00
Filed: 1982-03-13
Abstract: The invention relates to a gate valve for gas lines in particular, consisting of a valve housing with a gas inlet connecting piece and a gas outlet connecting piece, with a valve seat between the gas inlet connecting piece and the gas outlet connecting piece, as well as of a valve closing body which is guided against the valve seat, is held in the open position by means of a restoring spring, can be moved into the closed position against the action of a spring by means of an operating device, and can move into the closed position independently of the operating device. In order to achieve automatic shutting off of the relevant gas line in the event of the effect of a fire, as a consequence of the temperature rise resulting therefrom, an expanding material cartridge is arranged between the valve closing body and the operating device. This expanding material cartridge has an expanding bolt which moves axially and operates coaxially on the valve closing body, and is operated by the expanding material in the expanding material cartridge expanding at the predetermined temperature. A blockade of the extended expanding bolt, which presses the valve closing body down onto the valve seat, is achieved with the aid of a backstop which is allocated to the expanding bolt and is mounted on the expanding material cartridge. <IMAGE>

Title: Method of joining metallic inner and outer parts of a composite profile
Inventor: ENSINGER WILFRIED DIPL ING
IPC: B29C65/68
Filed: 1982-06-09
Abstract: The invention relates to a method of joining the metallic inner and outer parts of a composite profile by an insulating tongue, which engages with its ends in grooves of the inner and outer parts, in which an additional material in the form of at least one wire, strip or cord is introduced in the region of the ends of the insulating tongue and modified in its material properties by pressure and/or heat, in particular deformed, in such a way that an improved positive, non-positive and/or integral connection is obtained between insulating tongue and the inner and outer parts of the composite profile. In order to simplify the introduction of the additional material and consequently the production of the composite profile altogether, it is envisaged that a body which can expand in the transverse direction of the material and onto which an adhesive sheathing is applied is used as the additional material.

Title: Method for feeding bulk material into the buckets of a feeding bucket elevator, in particular of a high-capacity bucket elevator, and feeding bucket elevator, in particular high-capacity bucket elevator, for implementing the method
Inventor: KOSTER KARL H DR ING
IPC: B65G47/18
Filed: 1982-09-29
Abstract: In a high-capacity bucket elevator, the bulk material is fed by means of a number of sliding surfaces (11, 12, 13), positioned one above the other, to the buckets (3) which run past the sliding surfaces, so that, as a result of the relatively long sweep-over time per bucket of the bucket elevator, the degree of filling for each individual bucket is correspondingly high. The upper sliding surfaces (12 and 13) are provided with screening plates, which makes it possible for the bulk material to be classified such that the buckets are charged firstly with finer-grain bulk material and finally with coarse bulk material. <IMAGE>

Inventor: TEICHMUELLER GERHARD
IPC: C07J1/00
Filed: 1982-11-12
Abstract: The invention relates to a process for separating 4-androstene-3,17-dione/1,4-androstadiene-3,17-dione mixtures as are produced, for example, in microbiological sterol side-chain degradation, by conversion into 17 beta -cyano-17 alpha -hydroxy-4-androsten-3-one/17 beta -cyano-17 alpha -hydroxy-1,4-andr ostadien-3-one mixtures from which the sparingly soluble 17 beta -cyano-17 alpha -hydroxy-4-androsten-3-one is removed in crystalline form by filtration, and the 17 beta -cyano-17 alpha -hydroxy-1,4-androstadiene remaining in the mother liquor is cleaved back, directly or after extraction with organic solvents, by treatment in alkaline media into 1,4-androstadiene-3,17-dione and isolated as such. The products are separated in high yields and sufficient purity for further processing to synthesise androstane and pregnane derivatives, as well as oestratrienes.
Patent DE-3305615-A1 (DE)
Title: Arrangement for securing a tube in a perforated plate by means of explosion pressure waves
Inventor: HAMPEL HEINRICH DR ING
IPC: B21D39/06
Filed: 1983-02-18
Abstract: The invention relates to a new type of arrangement for fixing a tube in a perforated plate by progressive explosive pressure. The arrangements known hitherto are unsuitable for certain technical constructional solutions, e.g. for welding in a tube in the region of the two surfaces of the perforated plate or for welding in a tube in tube plates while maintaining nominal dimensions of the tube after the explosion. The aim of the newly designed arrangement is accordingly, by means of an appropriate technical solution, to guarantee a leak-tight and firm connection of the tube to the perforated plate when fixing the tube in a perforated plate by explosive means, while at the same time eliminating crevice corrosion. This is achieved, according to the invention, by the fact that the parts of the tube end which are situated in the region of the two surfaces of the perforated plate taper and that there is a gap between the wall of the bore and the outer wall of the narrowed parts of the tube end. This arrangement opens up new possibilities for fixing the tubes in the required technical areas of application.

Title: Centring device for upright receptacles, especially in labelling machines
Inventor: EDER ERICH
IPC: B65C9/06
Filed: 1983-03-10
Abstract: A centring device for receptacles has a standing plate (21) and a centring ring (23) which surrounds the standing plate (21) and has a funnel-like centring surface (29), both being mounted so as to be independently vertically movable on the rotary plate (4) of a turntable (1) in a labelling machine. The upper end positions for the standing plate and the centring ring are determined by stops (23, 26) and for the standing plate in addition a lower end position is determined by another stop (4). A vertically movable centring bell (11) with a lifting cam (18) is assigned to the rotary plate, which lifting cam is designed in such a way that the centring bell lowers the receptacles with the standing plate to the latter's lower end position, in which process the centring surface comes to rest against the receptacle, centres it and is then lowered with it. In this way, precise centring together with the maintenance of a constant height for the receptacles is possible regardless of tolerances in the receptacle diameter. <IMAGE>

Patent DE-3319921-A1 (DE)
Title: Process and equipment for preparing finely divided dispersions
Inventor: SCHNOERING HILDEGARD DIPL PHYS
IPC: B01F5/00
Filed: 1983-06-01
Abstract: For preparing very finely divided emulsions (particle size </= 2  mu m), a non-conveying rotor/stator dispersing machine having only one toothed stator ring and one toothed rotor ring arranged concentrically at a distance of 0.05-0.6 mm, which is caused to rotate at a circumferential speed of 30 to 100 m/s. At the same time, the throughput in the machine is adjusted by means of an upstream supply pump in such a way that the residence time of a liquid element in the shear zone is between 0.001 second and 1 second. The residence time here results from the quotient of the shear gap volume and the volumetric flow which is in turn determined by the delivery rate of the pump. The important point here is that the available dispersing power is converted in a single dispersing zone of relatively small volume. In this way, high volume-related dispersing powers in the range from 1 kW/cm<3> to 200 kW/cm<3> can be achieved. The process is suitable especially for emulsifying disperse systems with an aqueous outer phase or other outer phases of comparable viscosity, which are otherwise difficult to emulsify. <IMAGE>

Patent DE-3330478-A1 (DE)
Title: Heating plant with an electrically heatable heat storage tank
Inventor: NIED PETER
IPC: F24D19/10
Filed: 1983-08-24
Abstract: A storage container (1) is heated in case of need, during possible boosting times, with high tariff current. The supply of this expensive energy is started by a switch (6) which is closed and opened in dependence on the position of the mixer (3). When the temperature in the storage container (1) has fallen nearly to the required forward flow temperature, the displacement rod (15) of the mixer is located in or near an end position and closes the switch (6), so that the load contactor (7) is closed and the supply of energy begins. When the temperature in the storage container has again exceeded the required forward flow temperature by a predetermined amount, the displacement rod (15) will have moved so far that the switch (6) is opened again and hence the supply of expensive current is interrupted. The control by means of the mixer (3) has the advantage that all the parameters which are relevant to the extent of the boosting are taken into account with a simple circuit. <IMAGE>
