Abstract: A former is used to fold webs longitudinally. During the web drawing-in process; the individually incoming paper webs in a group of paper webs are conveyed smoothly to a folding mechanism at the end of the former. This is accomplished by using a number of upper and lower transport elements which are located above and next to each other at least inside the boundaries of the upper surface of the former. These upper and lower transport elements can be brought together and can be separated. They can be driven as desired.

Abstract: A turning bar arrangement for paper webs in a web-fed printing machine provides a compact and space-saving construction. A pair of turning bars are connected to each other while forming an acute angle and are mounted so that they can be displaced in a first plane of the turning device. A second similar arrangement of turning bars is provided in a second plane of the turning device.

Abstract: A paper web is drawn into a printing and can be guided along a selected one of several paths. The paper web is weakened along a line of separation and is then held by a retaining system that can move the web in a conveying direction along a first path. The web is fed to a different conveying path and is separated ot torn along the line of separation. This line of separation or weakening is formed at an angle to the production direction.

Abstract: Coded retrievable signal information is applied to a paper web leading end prior to the paper web being directed to a print unit in a rotary, web-fed printing press. This signal information is scanned by signal reading devices and is forwarded to adjusting elements along the path of travel of the web through the press. These adjusting elements set the path of web travel to its final destination and also synchronize the printing units and the cutting units for the paper web.

Abstract: Dihydronaphthalene compounds have excellent 17&agr;-hydroxylase/C17-20-lyase inhibiting activity, thromboxan A2 synthesis inhibiting activity, and aromatase inhibiting activity and are thereby are useful as preventive and/or therapeutic agents for various male sex hormone- and female sex hormone-dependent diseases such as prostate cancer, prostatomegaly, masculinization, breast cancer, mastopathy, uterine cancer, endometriosis, and ovarian cancer, as well as myocardial infarction, angina pectoris, and bronchial asthma.

Abstract: Guide rollers in a web-fed rotary printing press are cleaned by a web of material that is provided with signal information, such as a bar code or a punch code. The retrievable signal information is used by one or more signal reading devices that are used to apply cleaning agent to the web and to create a speed differential between the guide roller and the material web.

Abstract: An endless web of material, such as a web of paper, is drawn into a device by using moving traction devices along the path of web travel. Web guide rollers that support the web in the device are accelerated before the arrival of the leading end or the beginning of the material web.

Abstract: A moving paper strip or web is cross-perforated by a perforation roller in cooperation with a counter roller. The perforation roller has a plurality of axially spaced retractable perforation plungers. These perforation plungers form a helical line of plungers on the circumference of the perforation roller to perforate left rising or right rising tear line extending in a direction oblique to a paper web movement direction to form a draw-in tip after separating the paper web along the tear line.

Abstract: A paddle wheel is used to deliver folded products to a conveyor belt in a shingled fashion. The paddle wheel has a plurality of pockets which are formed by circumferentially spaced curved paddles. The thickness or width of each product receiving product is adjustable by providing a guide strip in each pocket. The end of the guide strip adjacent the bottom of each pocket can be shifted radially with respect to the axis of rotation of each paddle wheel by actuation of a drive assembly.

Abstract: An insulating feedthrough for an electrostatic precipitator has a cylindrical insulator passing through a hole in the wall of the precipitator and having an annular flange which is sealingly pressed against the inner surface of that wall by a clamping arrangement including a spring. A tubular bushing extends through the insulator and has a flange bearing upon the inner end of the latter which is connected by a clamping arrangement to a flange on the support for the electrodes via another spring. A rod for transmitting rapping blows passes through the bushing to impact against the electrode support.

Abstract: Disclosed is an electrofilter for the removal of dust from gases under a pressure of up to 30 bar and a temperature up to 500.degree. C. The electrofilter has a vertical cylindrical pressure casing having a lower chamber for the accommodation of the precipitating electrodes and spray electrodes, an upper chamber for the connection of the gas ducts and the disposition of the insulators, as well as a funnel-shaped dust collector. The upper chamber is divided horizontally and vertically by walls to permit a double-filter effect, and to thermally insulate the insulators from the flowing-gas chamber.

Abstract: This invention relates to the part of a tubular electrostatic precipitator for a vertical gas flow, comprising a bank of circular cylindrical collecting electrodes of plastic material, at least one upper tube sheet, at least one lower tube sheet, and a cylindrical housing. The housing consists of a steel shell, which is provided with an acid-resisting coating at least on its inside surface, the tube sheets consist of plastic meterial, the circular cylindrical collecting electrodes are fixed by welding in the upper tube sheet, and the entire free space which is available between the tube sheets outside the collecting electrodes is filled with foamed plastic material as far as to the inside surface of the housing.

Abstract: A process for producing a honeycomb of synthetic-resin material for use as the collector electrode of an electrostatic precipitator comprises assembling the honeycomb from plate strips having the cross section of sheet piling and made by hot molding from unsaturated polyester resins, glass fibers and nonwoven external covering fabrics of synthetic fiber. The honeycomb structure, which has a hexagonal ducts, is then provided with a shell of glass fiber and polyester resin by a winding operation. Conductive pigments, such as carbon and metal oxides, and flame-inhibiting additives can be incorporated in the unsaturated polyester resin.
