Abstract: In a device for controlling access in a passage lane, particularly for controlling people, comprising a housing for receiving electronic components, particularly comprising a reader for tickets, the housing forming a lateral delimitation of the passage lane, it is suggested, for simple and rapid maintenance and putting into operation, that the housing have housing openings (3) directed toward the passage lane (2), the housing opening (3) be closable by covers (4), and at least two of the covers (4) be implemented as supports for electrical and/or mechanical modular components, particularly an identification module for tickets, a controller component for controlling an access control, a data transfer module for data exchange with further electrical and/or mechanical components, and/or a display module for displaying information, the particular modular components being positioned on an interior of the cover (4) implemented as a support, and being replaceable together with the cover (4).

Abstract: An access control gate with a mechanical guidance forms one or more access lanes for patrons. First electronic means include a contactless access reader which is connected to a software controlled verification system to identify the access right of patrons, second means comprise two motor driven flaps which protrude from left and right of the lateral lane boundaries into the access lane thereby forming the closed gate threshold 4. The contactless access reader is arranged to capture the access right of the approaching patron short before he approaches the gate threshold 4. The verification system 13 activates the flaps 7 and 7? when an access right has been approved to swing out of the lane A to indicate to the approaching patron the granted access right.

Abstract: An impact mill including a base portion on which is disposed a rotor rotatably mounted in a bearing housing, the rotor having an upwardly aligned cylindrical surface portion coaxial with the rotational axis. The impact mill is provided with a mill casing within which is located a conical track assembly which surrounds the rotor to form a conical grinding path. The mill casing is provided with a downwardly aligned cylindrical collar which may be axially adjusted to set a grinding gap between the rotor and the mill casing. The rotor is provided with a plurality of impact knives complementary with a plurality of impact knives disposed on the inside top surface of the mill casing. In addition, the impact mill can be formed of separated conical sections. Finally, power is transmitted to the rotor of the impact mill by a synchronous sprocketed belt, accommodated by a sprocketed drive sheave, wherein the belt is in communication with a power source.

Abstract: In a device for access control, the authorizations are stored on tickets in the form of a barcode. A reader unit is connected to an evaluating unit and controls devices that signal and/or block access. The reader unit has an insertion zone for a ticket wherein the insertion zone is larger than a ticket dimension. A multidirectional laser scanner scans the entire insertion zone in several lines oriented at an oblique angle relative to one another. The device can be used with different ticket formats such as air-travel tickets and check cards.

Abstract: An access control system includes at least two access routes (2, 2′) which can be blocked with controllable barriers. The access control system further includes an antenna (A1, A2) associated with each of the access routes, and a control device (1) for evaluating access authorization cards, e.g. RFID transponders, which operate without making galvanic contact. Each antenna (A1, A2) is connected to a corresponding transmit/receive unit (13, 14), and the terminals of the antennae (A1, A2) associated with the access routes (2, 2′) are connected to a deactivation device.

Abstract: A fire-retardant plastic mixture contains 55%-75% by weight of boehmite which has an orthorhombic crystal structure and has the general formula AlO.sub.x (OH).sub.3-2x with x-values ranging between 0.8 and 0.99, and has a mean grain diameter d.sub.50 ranging between 0.4 and 0.7 .mu.m, a d.sub.10 value ranging between 0.7 and 1.2 .mu.m and a d.sub.90 value ranging between 0.2 and 0.4 .mu.m. The filler material is used in the form of a finely-crystallized hydrargillite which is obtained during a precipitation process according to Bayer with a grain diameter of 0.5 to 3 .mu.m, which is suspended and which, without any mechanical working, is transformed directly in a hydro-thermal process at temperatures ranging between 220.degree. C. and 240.degree. C. under turbulent conditions into a boehmite of the general formula AlO.sub.x (OH).sub.3-2x with x-values ranging between 0.8 and 0.99.

Abstract: A component for cladding apertures in the fuselage of an aircraft is to be of lighter weight and more corrosion resistant as compared with known claddings. The component is manufactured of carbon fibre reinforced curable synthetic resin and comprises a base layer (2) onto which U-profiles (4, 4') and L-profiles (5, 5') are placed in spaced apart interrelationship, which during the manufacture are held in place by a grid (14) comprising angular bridge members. A vacuum foil 7 is applied over this assembly and is adhesively bonded along the edges of the base layer (2') to the supporting surface (1). The space between the vacuum foil (7) and the supporting surface (1) is evacuated and curing proceeds at an elevated temperature and pressure. After complete curing the vacuum foils (7) and the grid (14) are removed.

The ski body component is a prefabricated component which is formed from a core (3), steel edges (6 and 6', respectively), a running surface coating (7) and possible intermediate layers. To produce the ski, the prefabricated ski body component (1) is introduced into a trough-shaped mould (9), a space being left free for the production of the trough, whereupon the free space is filled with plastics material, preferably by a RTM method.

Abstract: In a pipe line for an engine, in particular a cooling line in aircraft construction, the walls of the pipe line are composed of a load-bearing inner layer (2) of fibre reinforced, curable synthetic resin and of a heat insulating outer layer (3) of fibre reinforced curable synthetic resin, bonded to the inner layer (2). For the production of the two layers (2, 3) a removable core (1) is used, for example composed of a low melting metal alloy.

Abstract: In a frame (1') for ball game racquets made of plastic the abrasion and cutting of the guts against the edges of passages in the frame is avoided. For that purpose the frame (1') comprises a center strip (3) of thermoplastic resin, the hardness of which is less than or equal to the hardness of the guts. Hollow profiles (4, 5) of duroplastic, fibre-reinforced synthetic resin are moulded onto both sides of the center strip. The passages are drilled into the center strip (3) after the frame has been produced and then the frame is strung.

Abstract: A roller for paper or foil sheet handling machines such as printing presses comprises a cylinder consisting of fiber reinforced plastic material including alternate layers of circumferentially wound fibers and helically wound fibers. The helically wound fibers are arranged in groups of strings which are spaced from one another so as to form rhombus-shaped depressions in the surface of the cylinder, thereby providing rollers of relatively low masses but high strengths which have surfaces capable of firmly engaging the paper or foil sheets.
