Patent DE-4102408-A1 (DE)
Inventor: SAALFRANK WERNER DR ING
IPC: H04H20/67
Filed: 1991-01-28
Abstract: The invention concerns a procedure for use in common-wave radio broadcasting. For common-wave broadcasting, it is necessary for the modulation content of the transmission frequencies (B1, B2, B3, B4) of the individual broadcasting stations to be identical. In order to make transmitter or regional identification possible, however, one or more additional carrier frequencies (B2, B3, B4) which differ from each other from region to region are emitted, reception of these additional carrier frequencies making it possible to select at the receiver specialized regional news. The number of additional carrier frequencies required can be reduced to four individual frequencies or groups of frequencies if the additional carrier signals are modulated with identification signals.

IPC: G01N33/36
Filed: 1991-09-23
Abstract: The invention concerns a method for detecting and counting defects in a length of yarn, using a camera (5), a computer (8) and an image-processing programme. The yarn (30) is illuminated at an intensity dependent on the diameter of the yarn (30) and an image recorded by the camera (5). The image thus recorded is digitized in the computer (8) by means of the image-processing programme and low-contrast points filtered out. The remaining points are collected to form cohesive zones which are classified according to predetermined sizes and stored in a memory. The device used to carry out the method is designed to accommodate two yarn spools and has a camera (5) as well as two guide rollers (15, 16), disposed a certain radial distance apart, over which the yarn (30) is deflected, at least one (16) of the guide rollers being driven.

Title: Release system for hump shunted rakes of railway trucks - uses detected characteristics of standard rakes varied to suit others by taking into account weight concentrated at front and rear of rake
Inventor: SOREMBA VOLKER DIPL ING
IPC: B61J3/02
Filed: 1991-11-29
Abstract: The release characteristics of standard rakes are detected, and the actual positions where their release takes place are determined. These points are correlated with the brake length, distance between outermost axles, truck type, number of axles, etc. and used as release point factors (LFB). The sum- and residual-sum-frequencies (SH,RH) for the factors of the individual classes are calculated. From them maximum and minimum values are derived giving the earliest and latest release points to be expected for 95% of all the types of rake. When determining the speed at which rakes are pushed over the hump, the weight concentrated at the rear end of the leading rake and that at the forward end of the trailing one are taken into account. USE/ADVANTAGE - High output rate even where the positions of the centres of gravity of the individual rakes are unknown before shunting starts.

Title: High temp. resistant sintering support base - made of viscous mass with inorganic particles protruding from the surface to produce support for sinter prods.
Inventor: NORMANN ALFRED
IPC: F27D5/00
Filed: 1992-02-27
Abstract: A sintering support surface is made by pouring a highly viscous mass made up of high purity, chemically inactive inorganic powder, 20-70 wt.% H2O and 5-50 wt.% organic binder onto a steel strip to produce a layer 0.3-2 mm thick. Immediately as the viscous layer is cast, an inorganic powder is uniformly sieved or sprinkled on top such that the grains partially sink into the mass. During latter sintering reaction the grains are effectively anchored into the substrate with part of their surface protruding from the substrate to produce a space "a" between the substrate surface and the bottom of articles to be sintered. ADVANTAGE - Reusable support surface which is chemically inert towards the sinter products, has good resistance to thermal changes and permits no capillary action as the pores of the substrate are spaced apart from the sinter prods.

Filed: 1992-03-20
Abstract: The invention concerns a set of products to be packed (1, 2), in particular oil-impregnated cloths (6, 7), enclosed in an outer package. On the top side of the set (1,2) is fixed a synthetic piece (12) with an upper covering panel, cap or simple frame unit, and with a closable aperture (8) from which the material is taken and which is provided with a closing lid (15) or cap. An outer cladding layer (5) is fixed and sealed off from the underlying layer by means of a seam (20), with a section which extends outwards around the aperture (8), and the enclosed region of the set of products (1, 2) is simultaneously sealed off. The cladding layer (5) is in the form of a tubular bag (21), a seamed bag or a bag with a fixed base. Opening aids provided around the aperture facilitate tearing and the removal of the cladding section in that area. A groove can be made in the cladding between two longitudinal ridges or in a notched line in the synthetic piece (12); alternatively, the latter can be opened up along an embossed line by means of a projecting lug and removed via a low-adhesion secondary inner seal. The large covering lid (15) can then be opened and closed.

IPC: B23B31/20
Filed: 1992-03-24
Abstract: The tool shank (2) is gripped by the collet (1), which fits into the taper bore (4) of a machine tool chuck (5) and is closed by tightening the ring nut (6). Between the ring nut and collet is interposed a pressure ring (7) having a taper bore (9) fitting the front taper (8) of the collet, and a parallel guide bore fitting the nose (12) of the chuck with a small clearance. When the ring nut is tightened, the axial closing force on the collet is exerted through the pressure ring, which is held concentric by the fit of the guide bore on the chuck nose (12). Equally spaced around the end face of the ring nut are set screws (18) which bear against the end of the pressure ring in a shallow track (20). Any remaining run-out of the tool can be reduced to less than 5 micron by appropriate adjustment of the set screws. ADVANTAGE - Run-out of tool can be minimised. Commercially available collets can be used.
