Patent DE-3242032-A1 (DE)
Title: Method for dyeing textile goods made from modified polyester fibres by the pad-batch technique
Inventor: MUELLER SIEGFRIED DR
IPC: D06P3/52
Filed: 1982-11-13
Abstract: Poor wet-fastness properties and unsatisfactory thermofixing fastness in dyeings on carrier-free dyeable polyester fibres using conventional disperse dyes exclude the use of textile goods of this type in the contract sector, such as consumer textile goods, sportswear etc. The decreased boil wash resistance of such disperse dyes on the modified fibres can lead to problems because of the risk of bleeding-out during the wash. By the use of disperse dyes containing reactive groups for the dyeing of carrier-free dyeable polyester fibres by the pad-batch technique, the dyeing results in relation to the fastnesses sought are considerably improved and thus further areas of use for the fibre types mentioned are opened up.

Title: Bookmark and line indicator
Inventor: SCHMIDT ALFRED
IPC: B42D9/00
Filed: 1982-12-07
Abstract: In order to enable pages and lines to be recorded and found again in books, periodicals, files, catalogues, lists, telephone directories, etc, a strip of material (preferably of transparent plastic) bent into the form of a clamp or clip with legs of unequal lengths, may be printed with any desired symbols, for example a line, which can be set exactly to the desired line when the bookmark is clipped onto the appropriate page of the book, by displacement of the said bookmark, as a result of which it is made possible subsequently to find the page and line again immediately, the legs of the bookmark each being able to be cut to length as required. If use is made of thin or flexible material to produce the bookmark, the bending point may be provided with a reinforcement, it being possible for these or the former to be differently coloured when a plurality of bookmarks are used. <IMAGE>
Patent DE-3305270-A1 (DE)
Inventor: SCHREINER HORST PROF DR
IPC: H01H1/02
Filed: 1983-02-16
Abstract: AgCdO based contact elements are replaced in contactors and small circuit breakers with CdO-less type elements which exhibit little burn-off in the arc, a low welding force and minimal heating when carrying continuous current. However, known AgSnO2 contact materials do not have optimum values in all operationally important properties. In these contact materials a more firmly adhering oxide layer occurs as compared with AgCdO. The invention relates to a sintered compound material for electrical contacts, consisting of AgSnO2Bi2O3CuO and containing at least one other metal oxide additive which sublimes below the melting temperature of silver. The SnO2, Bi2O3 and CuO are globularly precipitated in silver material structure zones having a maximum diameter of 200  mu m, and the metal oxide additive is distributed on the surfaces of the boundary regions of these microscopic silver zones.

Patent DE-3308028-A1 (DE)
Title: Industrial steam power installation
Inventor: WIESER RUDOLF DR
IPC: F23L15/04
Filed: 1983-03-07
Abstract: The proposal according to the invention relates to industrial steam power installations, the steam boilers of which were originally operated without preheating of the combustion air. By means of retrofitted devices (bleed-steam-heated combustion air preheater), it is possible, by two- or multi-stage preheating of the combustion air by bleed-steam flows from the steam turbines, to create the precondition for the generation of additional electric energy with an efficiency of "one". It is thereby possible to produce especially cheap electric current while at the same time providing optimum protection of the environment from waste heat and pollutants.   If required, back-pressure steam turbines must be installed and modifications to the steam boilers have to be made. In addition, proposals are made for the arrangement and design of particularly space-saving, light and cheap bleed-steam-heated combustion air preheaters. <IMAGE>

Title: Reference value transducer for a temperature regulator
Inventor: REINHARD SIEG
IPC: G05D23/24
Filed: 1983-03-11
Abstract: The present invention relates to a reference value carrier for a temperature regulator of a heat source for a central heating system, with a bridge circuit, one branch of which has a reference resistor for the desired room temperature and the other branch of which has a resistor dependent on the external temperature and a fixed resistor in series, and in which the bridge diagonal is formed by a slider of the reference value resistor and the junction of the external temperature- dependent resistor with the fixed resistor and is passed to an amplifier, which has in its output the regulator for the heat source. To solve the problem of providing the operator of a heating installation, or the installer, with the possibility of adjusting the reference value, in which the heating curve can be set exactly based on normed values, according to the prior heat requirement calculation, and experimentation to find the correct position of the heating curve can be avoided, the invention consists in that the junction point (21) between the resistor (13) dependent on the external temperature and the fixed resistor (14) is connected to the amplifier (18) with the insertion of a resistor (28-32) equivalent to a normed external temperature, and in that a trimming resistor (35) is in parallel with the amplifier (18) and has a set value which is an image of the design temperature of the heating installation. <IMAGE>

Title: Method for providing DC voltage sections in power supplies having semiconductor AC power controllers
Inventor: KUNTZ EDUARD ING GRAD
IPC: H02M5/257
Filed: 1983-05-13
Abstract: In an AC load (1) to which a supply voltage which is present at the output of a mains-supplied semiconductor AC power controller (2) which is controlled by control pulses from a controller (8, 9, 10, 11) is applied, it is intended to ensure that there is either no DC voltage component, or only a defined, small DC voltage component, in the supply voltage. This is done by driving the semiconductor switches of the AC power controller (2) asymmetrically in the two mains half-cycles. For this purpose, the DC component is detected via a DC voltage filter (3) and is compared in a regulator (4) with a reference variable which corresponds to a predetermined, desired DC voltage component in the supply voltage. The control deviation of the regulator (4) influences, as an additional control variable, a synchronising voltage in the mains filter (8) of the controller of the AC power controller (2), as a result of which asymmetric control pulses are formed. <IMAGE>

Abstract: A protective device (1) (Fig. 1) has a protective shield (2) which is mounted adjustably on a holder (3). The protective device serves to shield against X-radiation (Pf 2) on one side of the shield (2) by comparison with the operating zone (26) on the other side of the shield (2). The protective shield (2) has two mutually spaced, parallel guide plates (4, 5) between which juxtaposed blade elements (6) which are guided displaceably relative to one another are supported. Said blade elements can emerge at the lower end of the shield (2), and they rest with their lower ends (15) on a patient, in accordance with the body contour (16). In so doing, the lower blade regions form a ray-proofing fence automatically matched to the body contour (16). Both the blade elements (6) and at least one of the guide plates (4 or 5) consist of ray-shielding, in particular lead-containing material. The protective shield (2) can be mounted both in the longitudinal direction and in the transverse direction on a X-ray table, in particular by use of an adjustable holder (3) on standard longitudinal rails (17) of the X-ray table or the like. <IMAGE>

IPC: C10B21/12
Filed: 1984-02-10
Abstract: The invention relates to a heating device for coke ovens with heating walls subdivided by binders into vertical heating flues and with horizontal ducts located below the heating walls for feeding rich gas with vertical connecting lines to the individual heating flues, the control of the rich gas stream to the particular heating flue being effected by means of a calibrating nozzle which is located in the region of the heating flue bottom.
