Title: Apparatus for the contactless guidance of material webs
Inventor: VITS HILMAR
IPC: D21F5/18
Filed: 1988-07-05
Abstract: The invention relates to an apparatus for the contactless guidance of material webs 1. The apparatus has at least two blowing nozzles 2, 3 which are arranged one behind the other in the direction of run of the material web 1 and which extend transversely to the latter and are designed as slots or rows of holes. The blowing jets of these blowing nozzles 2, 3 are directed in the same direction and obliquely towards the material web 1. Provided on the side facing the material web 1 are flow-guide bodies 12, 12a, 12b, 13, of which the flow-guide body 12 adjacent to the blowing nozzle 2 located at the rear in the direction of run of the material web 1 is curved convexly towards the material web 1. The flow-guide body 12a, 12b located between the convexly curved flow-guide body 12 and the front blowing nozzle 3 is designed as an impact diffusor. By means of such an apparatus, a material web 1 is guided in a flutter-free manner even under difficult conditions. This effect is further improved if the flow-guide body 13 adjacent to the front nozzle lip 8 of the front blowing nozzle 3 is also curved convexly towards the material web 1. <IMAGE>

Inventor: ABENDROTH EBERHARD
IPC: D04B23/22
Filed: 1988-08-03
Abstract: In a method of producing a sew-knitted, net-like sheet structure weft and warp elements 4, 5, such as especially sheet strips, which initially do not possess the structure of textile filaments, are converted into filaments, which conversion can be carried out on the machine which produces the sheet structure. For this purpose, the weft and warp elements are sheathed by chain stitching, the sheathing of the weft elements in an advantageous case taking place in time before the connection with the warp elements and the warp elements being sheathed either before the connection or simultaneously therewith by the filaments which form the connection. As shown, strips, rovings or the like 4'', 4', 4'', 5, 5' are narrowed by means 6, 15, 21 prior to sheathing. Elements 5 are given an initial sheathing and then a second sheathing at the connection stage: elements 5' are sheathed only on connection; element 4 is used as a weft directly after sheathing while elements 4', 4'' are stored for future use. <IMAGE>

Patent DE-3836455-A1 (DE)
Title: Gaming machine
Inventor: DRESSELHAUS NORBERT
IPC: G07F17/34
Filed: 1988-10-26
Abstract: The invention relates to a gaming machine according to the main patent ... (Patent Application P 3717593.9). In this gaming machine, the scanning of the markings of the play bodies still necessitates a relatively high technical outlay which leads to high costs. This gaming machine is to be developed further to the effect that reliable scanning at a lower technical outlay also becomes possible. The present invention proposes three alternative solutions:   a) The marking of the play bodies is a light/dark bar code and scanning takes place by means of a bar-code reading unit; b) the marking takes place by means of a magnetic strip with data stored on this and a magnetic-strip reading head serves for scanning;   c) the marking consists of a code pattern consisting of strips or surfaces of differing heat capacity on the outer face of the play bodies and a thermal detector, in conjunction with a heat-radiation source, serves for scanning.   All the solutions afford the advantage that components known from other technical sectors can be used in the gaming machine for scanning the marking. This reduces the costs of development, production and repairs. The gaming machine is suitable for use in hotels or amusement arcades as a coin-operated gaming machine with a win pay-out. <IMAGE>

Title: Device for fastening a built-in apparatus (flush-mounted apparatus)
Inventor: FEUERLEIN FRIEDRICH
IPC: H02G3/18
Filed: 1988-11-12
Abstract: It is intended to create a fastening device, which is constructed as simply as possible, for built-in equipment, which device makes it possible to remove the equipment chassis from the front in the case of an equipment housing which remains in the switchboard, without any operation on the rear of the switchboard being required for this purpose. One recess (11) is provided in each of two side parts (10) which are arranged at right angles to the front and are connected to the front frame (1), which recesses are open to the exterior and are short in comparison with the installation depth of the equipment, and in which a tensile element (3) is located which slides over an inclined plane (12) which is constructed in the recess (11). The tensile element (3) can thus be sunk in the recess (11) for insertion of the built-in equipment, and can be withdrawn from the recess (11) with the aid of a threaded rod (7), for fastening of the equipment. The fastening device can be used for all built-in equipment. <IMAGE>

Title: Process and apparatus for cleaning the raw-material charging vessel of a processing machine
Inventor: ROTH UDO
IPC: B65G53/00
Filed: 1989-01-11
Abstract: A process for cleaning the raw-material charging vessel of a processing machine, in particular a plastics processing machine (M) provides that, once the charging vessel (2) has been emptied, a substantial quantity of air is passed through the said vessel in a surge in order to take with it particles adhering to the wall of the vessel. Preferably, a suction force is applied to the charging vessel (2) in order to develop a certain subatmospheric pressure once the outlet opening (10) has been closed, so that the amount of air exerting the said effect flows in the manner of a cyclone through the charging vessel (2) when the outlet opening (10) is opened. The process permits automatic cleaning of the charging vessels (2) of a multiplicity of processing machines which are supplied with raw material from a storage silo via a pneumatic suction conveying system. <IMAGE>

Patent DE-4000948-A1 (DE)
Title: Safety system for e.g. automatic machines - have one member moved from position set by second member by force exceeding set level and moved within distance limited by third member
Inventor: HATAMURA YOTARO
IPC: B24B55/00
Filed: 1990-01-15
Abstract: A safety system for machinery etc, has at least one member which is moved by another member when a force exceeds an adjustable given value; it has at least one static member to set the starting position of the moving member and at least one force-transmitting member to act on the two other members; the system also has means of limiting movement to a set amt. In an example a cylinder (1) has a partition (2) dividing it into two parts, each with a rod (5,6) fitted with flange (7,8) and pressure spring (9.10). One spring (9) is fixed to the partition (2); the other (10) is fixed to the other end (4) of the cylinder. The springs thus set the initial positions of the rods (5,6). If a force above a set level acts on the LHS end of the rod (5) this (5) moves and compresses the spring (9). A tension applied to the rod (6) moves the cylinder (1) to the left. The effect is that a force above a particular level moves the left hand or right hand half of the system and hence changes the distance between the ends of the two rods (5) and (6). ADVANTAGE - the system detects overloads in a reliable manner and releases them until the system is not endangered and then stops the whole layout.
Patent DE-4007508-A1 (DE)
Title: Spark-free coupling for two steel shafts - has bolted flanges on shafts enclosing laminar ring which faces all surfaces, prevented from sparking by e.g. polyurethane elastomer coating
Inventor: FUESER BERND
IPC: F16D3/79
Filed: 1990-03-09
Abstract: A flexible coupling for steel shafts has a flange on each shaft, and they are connected together to rigidly prevent turning, but to allow axial and angular movement by means of a laminar ring. Ring is fixed to alternate flanges by elements arranged round the circumference and is surrounded by a screen to prevent sparks from being produced if the laminate is fractured. This screen consists of an elastomer covering on the space round the ring, the elastomer pref. being a polyurethane. The laminated ring (2) covers the whole circumference of the coupling between the two flanges (1a,1b). It (2) is penetrated by bolts (3) plus their nuts (4) arranged round the circumference and fastened to alternate flanges (1a,1b). The outer female part (6) of another member (6) surrounds the ring (2) and is attached to the one flange (1b). The internal faces of the coupling towards the laminar ring (20 are covered (5a,5b) with elastomer, including the faces (5c,5d) of the additional members (6,7), so that the bores for the bolts (3) are similar. This construction prevents any fractured parts from striking steel surfaces and hence eliminates sparks. ADVANTAGE - The coupling is flexible and simple to  manufacture.
