Title: Drilling tool provided with internal cooling passages and having at least two flutes
Inventor: REINAUER JOSEF
IPC: B23B51/06
Filed: 1987-03-24
Abstract: A drilling tool provided with internal cooling passages and having at least two flutes is described in which a cutting part is put onto a support part. On the end face facing the support part, the cutting part has V-notches running through the drill webs and converging in the drill centre in the direction of the support part. Toothing surfaces, of corresponding or complementary design, of the shank part engage in the V-notches in a positive-locking manner for planar support. This self-centring connecting principle is suitable for a drilling tool with any number of flutes and, due to the multiplicity of toothed contact surfaces, it provides for the absorption of increased forces so that the drilling tool is suitable for maximum cutting capacities.

Patent DE-3723833-A1 (DE)
Inventor: EEUWIJK WILLY VAN DIPL ING
IPC: B61F5/32
Filed: 1987-07-18
Abstract: A resilient axle box guide rod bearing has resilient annular discs 47 retained within an eye at the end of the guide rod by dished bearing members 45, 46 sliding concentrically one within the other and serving as a two-piece horizontal axis having the ends 55, 56 secured to the bogie frame in brackets 57, 57' which a necked-down bolt 48 preloads in compression in the transverse horizontal direction. The shape and the material properties of the discs are such that at any preloading the spring rate for compression is greater than the spring rate for shear, the latter spring rate facilitating radial adjustment of the wheel sets. Guidance of the wheel sets supported in such resilient bearings is provided by connection of the axle boxes on each side of the bogie by guide rod & lever systems (Fig. 7, not shown) actuated by relative movement between vehicle body and bogie and also by means of transverse horizontal C-shaped frames extending one each around each wheel set, the frames being rigidly connected to the axle boxes and each having a connecting bracket extending towards the bogie centre, the apexes of which are interconnected- articulated for pivotting about a vertical axis. <IMAGE>

Title: Notchiness measuring instrument
Inventor: SELBACH GERD PROF
IPC: G01B11/24
Filed: 1987-09-17
Abstract: The measurement method based on this instrument can be used to determine the parameters which are bound up with the service life of a tool and are a function of the tool cutting edge and the surfaces of the tool. The notchiness measuring instrument is designed for use in workshops. A cutting tool introduced into a line-focused laser beam generates in the new condition sharply delimited reflections on reflection screens introduced into the beam path and having a geometrical arrangement with respect to one another which corresponds to the configurations of the tool cutting edges. Erosions and chips on the tool cutting edge appear as scattered beams on the reflection surfaces and are accessible there for analysis in terms of extent and positional angle. All the reflection screens rotate about a common axis on which the cutting edge to be measured is also located. The line focus is a reference for assessing the state of the cutting edge introduced.

Title: Arrangement for testing a printed circuit board
Inventor: BEHRINGER ROLAND
IPC: H05K1/18
Filed: 1987-09-24
Abstract: A printed circuit board, which consists of a board and integrated modules arranged thereupon, is tested according to the error-path method. In order to reduce a multiplicity of contacts between a measuring probe of an automatic test set and the individual connections of the modules arranged on the board, a test module (PC) is arranged between the module (BS) and the board (PL), the connections (PI) of the module being pushed through the test module (PC) to make contact with the board (PL). By this means, contact is likewise made between the connections (PI) and contact elements on the test module (PC). The connection elements of the test module can be connected to a measurement connector (MA) of the test module, e.g. with the aid of a multiplexer, and the level sampled there with the aid of the measuring probe. <IMAGE>

Title: Process and apparatus for the production of double loop-pile fabrics
Inventor: GOESSL RAINER DR
IPC: D03D39/16
Filed: 1987-11-09
Abstract: Process and apparatus for the production of double loop-pile fabrics, especially of double loop-pile carpets. The aim of the invention is the possibility of the simultaneous production of two loop-piled fabrics in an economically advantageous way and with high quality, at the same time with an increase in work productivity. The object of the invention is achieved in that there are arranged rigidly between the upper and lower fabric pile sinkers, on which are held upper-loop and lower-loop weft threads holding the loop tips of the pile loops which are suspended on them and which are formed in such a way that an upper-loop weft is inserted in the bottom shed over the upper pile threads and a lower-loop weft is inserted in the top shed under the lower pile threads. As a result of the transport of the fabric, the loop weft threads slide from the pile sinkers, the fabrics being separated into an upper and a lower fabric either without a cutting operation or with the cutting of the loop weft threads. Combinations of loop pile with cut pile and different heights thereof can also be produced. <IMAGE>

Title: Device for the uniform cooling of heat-treated particle-shaped material
Inventor: NIEMS LEE HOUSTON
IPC: F27D15/02
Filed: 1987-12-21
Abstract: Device for cooling a bed of heat-treated particle material such as for example lime from a furnace. The cooler has a shaft with, arranged below this, one or more funnels, through which the particle material flows, while cooling air is pressed upwards through them. Each funnel is circular with two inclines, an internal guide arrangement, an octagonal shaft and a matched octagonal mouth with shell-shaped transition segments. Alternative embodiments are made with transition pieces on the funnel itself instead of an octagonal configuration. The funnels contain stacked air inlet rings which are concentric with the funnel mouth and which are supplied with cooling air by air lines provided with control slides. An oblique flow guide ring is envisaged for compensating the intake rate. A distributor cone with an adapted frustoconical section guides the funnel material outwards from the top to the bottom and then inwards to the outlet on an annular path. A regulator body at the lower end of the frustoconical section allows a fine adjustment of the flow in order to make the temperature of the flowing material uniform and thus to increase the cooling efficiency. <IMAGE>

Title: Heating boiler
IPC: F23M9/06
Filed: 1988-05-11
Abstract: The invention relates to an angular connection piece for meeting hollow-profile sections, in particular plastic hollow-profile sections for window frames or the like, having a holding angle, forming angle legs, for bearing externally and in a securing manner on the meeting flanks of the profile sections at a frame corner. In order to design an angular connection piece in a manner simple in terms of manufacture in such a way that through it the profile sections to be connected to one another are held in a fixed, non-displaceable arrangement relative to one another and do not need to be used in order to connect the hollow chambers of the profiles, the invention proposes that a connecting web (13) extending into the open angle of the holding angle (12), and a second, inner holding angle (14) for bearing externally on the opposite inner flanks of the profile sections (1, 2) are provided. <IMAGE>

Patent DE-3819952-A1 (DE)
Title: Method for the flexible (soft-elastic) gluing of flexible components
Inventor: FRANCK ADOLF DR RER NAT
IPC: C09J4/00
Filed: 1988-06-11
Abstract: Technical problem of the invention. Rubber components are predominantly glued using rubber solutions. The disadvantage of this is that the solvent has to be evaporated before the contact faces make contact with one another. The contact faces can then no longer slide against one another, and, in particular, it is no longer possible for hoses to slide in one another. Solution of the problem. The precursor to the adhesive consists of the liquid monomer of an elastomer whose viscosity can be regulated by the addition of fillers or soluble, non-rigid polymers. When hoses slide in one another the precursor acts as a lubricant. After joining has been carried out the precursor is polymerised to form a flexible adhesive. Area of application: Glueing of flexible components, especially when they have to be telescoped into one another.

Title: Method for decoding digital signals
Inventor: SCHREITMUELLER WERNER DIPL ING
IPC: H04L1/00
Filed: 1988-06-28
Abstract: On the transmission path, RF noise pulses are often superimposed on individual symbols of coded digital signals. In order nevertheless to decode digital signals affected by interference of this type with a minimal error rate, the digital signals are subjected to multiple threshold discrimination (SE) in order to ascertain which data signal symbols are given a very low evaluation for the subsequent decoding with the aid, for example, of Viterbi decoders (DC1, DC2, DC3) because their levels lie above the respective discrimination threshold. The discrimination thresholds are shifted until one is found in which the decoded digital signals have an optimum error rate. This method is advantageous in the transmission of data from earth stations to satellites in the S frequency band, in which RF noise pulses occur due to terrestrial radar. <IMAGE>

Title: Radial flow turbine with spiral housing of variable flow cross-section
Inventor: SUDMANNS HANS
IPC: F01D9/02
Filed: 1988-09-17
Abstract: The invention relates to the radial flow turbine of an exhaust turbocharger with spiral housing of variable flow cross-section. A fixed outer spiral housing and an inner, axially displaceable spiral housing, extending in the outer spiral housing, serve as flow housing. The flow cross-section is reduced when the inner displaceable spiral housing rests on its free edge in the outer spiral housing. The fact that no restriction exists with regard to the shape of the spiral housing due to the provision of only two displacement positions is of particular advantage. With regard to its efficiency, therefore, the turbine can be optimally designed for two power ranges. In addition this also results in an easy control facility and smooth-running guiding of the adjustable spiral housing.   <IMAGE>

Title: Injection device for internal combustion engines with adjustment of the injection quantity
Inventor: LEMME WERNER
IPC: F02D1/10
Filed: 1988-10-01
Abstract: In addition to the positive adjustment required in most injection cases a negative or mixed adjustment of the fuel injection quantity is also often required. In the case of a mechanical governor a negative or mixed adjustment is very expensive and prone to faults owing to the complex construction hitherto known. By means of the injection device according to the invention, both a positive and a negative adjustment are accomplished with only one spring by an additional reverse lever. At the same time the facility also exists for combining both adjustments in the course of an injection pump. <IMAGE>

Title: Semiconductor switch
Inventor: SCHULZE HANS-JOACHIM DR
IPC: H01L31/111
Filed: 1988-11-07
Abstract: Semiconductor switch having a main thyristor and a separate auxiliary thyristor (1 and 2) which can be fired by light pulses and in which, on the one hand, the n-type base layer (11) of the auxiliary thyristor (2) is considerably less strongly doped and has a substantially greater layer thickness than the n-type base layer (5) of the main thyristor (1), and in which, on the other hand, a photosensitive gate pattern (21a, 22a) is implemented, which is integrated into the auxiliary thyristor (2) and has substantially greater lateral dimensions than in a conventional auxiliary thyristor. By these two measures, the firing sensitivity is increased, without the dU/dt behaviour of the auxiliary thyristor deteriorating. Instead of enlarging the layer thickness of the n-type base layer (11) it is also worth considering incorporating an n<+>-type stop zone (47). <IMAGE>
