Patent DE-3602419-A1 (DE)
Title: Generating milling cutter for composite materials
Inventor: FLEMMING JOERG
IPC: B23Q11/00
Filed: 1986-01-28
Abstract: The generating milling cutter has a cutting-edge geometry specially adapted to the working of composite materials. Two main cutting edges, which run towards one another in the form of a wedge in the direction of increasing length of cut, are arranged axially one above the other on the periphery of the milling cutter. In a preferred embodiment, the two main cutting edges are convexly curved, so that in side view the entire cutting face is parabolic. As soon as the two main cutting edges touch the upper and lower edge of the workpiece, as well as the forward-feed forces and the forces normal to forward feed high passive forces FP act on the outer layers of the material. The outer layers are separated off - as it were cut - and with the advance of the milling cutter cutting edge the inner regions of the workpiece are also sheared off. By virtue of the fact that first the outer layers and then the inner region is cut, the course of the cutting force is very uniform. A cut edge of high accuracy and surface quality results. Advantageously, the powdery or fibrous chips produced are directed via recesses under the cutting edges into the hollowed-out milling cutter interior and removed from there by suction.

Title: Method and arrangement for recognition of falsified messages in logging devices
Inventor: LIEPELT REINHARD DIPL ING
IPC: G06K1/12
Filed: 1986-02-12
Abstract: To make it possible to recognise falsified messages in logging devices without intense concentration and comparison with other messages, the invention proposes a method, in which:   &cirf&  The message to be logged, which is produced in a secure computer, consists of characters which are each made up of at least two partial characters (1a, 1b in Fig. 1), which only become a valid character (e.g. "P" in Fig. 2) when they are combined. &cirf&  The computer transmits the partial characters (1a, 1b) as coded signals, one after the other or simultaneously. &cirf&  The logging device combines the partial characters (1a, 1b) into human-readable characters ("P"), which it then combines into the log message.   <IMAGE>

Patent DE-3605497-A1 (DE)
Title: Removable supporting roller
Inventor: SIMANAINEN JYRKI
IPC: B65G39/12
Filed: 1986-02-20
Abstract: Removable supporting roller (2) for moving objects subject to heavy loads, e.g. for the dewatering drum (1) of a drum press. Known supporting systems have the disadvantage that rapidly wearing supporting rollers cannot be replaced without first lifting the object or apparatus supported by them. However, this is often difficult because of a shortage of space or a lack of lifting equipment. In the case of the supporting rollers according to the invention, this problem is solved by the formation of notches (5) at the ends of the axle (3) of the supporting roller (2), by mounting the axle (3) at the ends in slots in the supporting structure (8), and by locking the axle (3) non-rotatably by means of fastening members (4) mounted on the supporting structure (8) at the ends of the axle (3). <IMAGE>

Patent DE-3627878-A1 (DE)
Title: Circular polarisation device
Inventor: DANZ RAINER DIPL PHYS
IPC: G02B27/28
Filed: 1986-08-16
Abstract: The invention relates to a circular polarisation device in which the conditions of contrast and resolution for the application of finitely opened light bundles are improved in a wide spectral range of visible light. The aim is to guarantee the generated path difference of a quarter wavelength (phase difference  pi /2) simultaneously over a large spectral range and as large as possible an aperture angle of the bundle inside a prescribed minimum tolerance. The object is therefore to configure an arrangement of totally reflecting quarter-lambda retarders each having two totally reflecting surfaces. This is achieved according to the invention when the angles of incidence are selected such that they are larger than the angle of incidence, which upon reflection causes the maximum in the phase difference between the p- and s-components of a lightwave polarised linearly at an oblique angle relatively to the plane of incidence. The retarders are arranged in the telecentric beam path downstream of a linear polariser or upstream of a linear analyser. <IMAGE>

Title: Water-inflow device for domestic appliances
Inventor: KAEFFERLEIN HEINZ
IPC: A47L15/42
Filed: 1986-12-22
Abstract: In a water-inflow device for domestic appliances, there is provided a riser pipe (3), through which most of the inflowing water passes into a tub of the appliance. An overflow edge (6) leads from the riser pipe (3) into an overflow channel (7) which opens into a lower air-trap chamber (8). Connected to the air-trap chamber (8) is a siphon line (12) opening into an expansion vessel (13), into which a part-water stream is also guided through to the tub during the inflow of water for the purpose of flushing free of dirt particles. In order, at the same time, to prevent liquid flowing in via the expansion vessel (13) and via the siphon line (12) from passing into the air-trap chamber (8) before the liquid level in the tub of the appliance reaches the level of the overflow edge (6), at least one cross-sectional widening (22) is provided in that portion of the siphon line (12) rising from the chamber (8), and, while the siphon line is being used during the emptying of the expansion vessel, there remains in the cross-sectional widening (22) a quantity of liquid which, at all events, flows back to the air-trap chamber (8) and at the same time closes the lower inlet orifice (11) of the siphon line (12). An overflow of liquid via the mouth orifice (17) of the siphon line to the air-trap chamber (8) is therefore avoided. <IMAGE>

Abstract: Molded, one piece articles having selected surfaces suitable for adherent metallization, molded metallized one-piece articles, and processes for making the said articles are disclosed. The molded one-piece articles may be formed by molding into a first mold cavity a first portion of the article using a first electrically insulating material which is an amorphous polymer resin capable of being adhesion promoted by an adhesion pro miting process and is catalytic for adherent metallization, or is capable of being rendered catalytic for adherent metallization by an activating process; inserting the first portion into a second mold cavity and molding into the second mold cavity a second portion of the article using a second electrically insulating material, leaving selected surface areas of the first portion exposed. The second material is a crystalline polymer resin resistant to the adhesion promotion process employed for the first material, non-catalytic for and incapable of being rendered catalytic for adherent metallization by the activating process employed for the first material. The exposed surface areas of the first portion of the article may then be metallized, e. g., by electroless metal deposition to form the metallized, one piece article.
