Abstract: In der Spannut (15) eines hier als Spiralbohrer augebildeten Schneidwerkzeuges sind quer zu einer Arbeitsschneide, dort der Umfangsschneide (6), etwa als Quernuten (62) ausgebildete Vertiefungen und als Segmentrücken (63) ausgebildete Erhebungen eingeformt. Die dadurch gebildete Wellenform setzt sich bis in die Arbeitsschneide (Umfangsschneide) (6) fort, so dass die Quernuten (62) als Spanbrechernuten wirken. Zudem ist am Grund der Spannut längs der spiralenförmigen Nutmittellinie (61) eine Grundwellenlinie gebildet, so dass das Spangut auf begrenzter Fläche anliegt und beim Transport quer zur Auflage- und zur Transportbahn pulsierend angehoben wird. Dem wird auch das an den Hauptschneiden (4,5) abgelöste Spangut unterworfen, wobei allerdings die Spanbrechernuten durch längs der Spannut verlaufende Leitrillen (23) gebildet sein können, die durch Leitrippen getrennt sind, was wiederum eine Minderung der Auflagefläche ergibt. Auf diese Weise werden die Haftkräfte des Spangutes in der Spannut (15) herabgesetzt, haftende Späne wieder abgelöst und der Spangutfluss verbessert. Die Erfindung bezieht sich schliesslich auf ein Verfahren zum Herstellen eines Schneidwerkzeuges, insbesondere Bohrer und/oder Fräser der erfindungsgemässen Ausbildung. Abstract In the flute (15) of a cutting tool shaped as a twist drill, recesses shaped as transverse grooves (62) and projections formed as segmentary ribs (63) extend transversely to the cutting edge, represented in this case by the circumferential cutting edge (6). The waves thus formed extend up to the cutting edge (circumferential cutting edge) (6), so that the transverse grooves (62) act as chip-breaking flutes. A wavy bottom line is also formed at the bottom of the flute along the spiral groove center line (61), so that the chips bear against a limited surface and are pulsatingly lifted during their transport transversely to the bearing and to the transporting path. The chips cut by the main cutting edges (4,5) follow the same path; the chip-breaking flutes may also be formed by guiding grooves(23) that extend along the the flute and are separated by guiding ribs, again with the result of reducing the bearing surface. The adherence of the chips within the flute (15) is thus reduced, clinging chips are removed and the flow of chips is improved. Finally, a process is disclosed for producing a cutting tool, in particular a drill and/or a milling tool, having the design of the present invention.

Abstract: Verrou complet (21) composé d'une pièce de verrouillage (34) actionnable et d'un ensemble de pièces assurant son déplacement. Ces pièces comprennent une poignée (37), un ensemble de transfert de couple (38) et un électro-aimant (39). La poignée (37) est actionnée librement sans qu'il faille la relier à l'électro-aimant pour déplacer la pièce de verrouillage (34). L'ensemble de transfert de couple (38), qui se présente sous la forme d'un bras basculant (63), est monté de manière à être actionné lorsque la poignée (37) est elle-même actionnée et prend ou abandonne la position de transmission de couple. En outre, l'électro-aimant (39) est disposé de manière à maintenir l'ensemble de transfert de couple (38) en position de transmission de couple quand le courant passe dans l'électro-aimant (39) pendant que l'ensemble de transmission de couple (38) est amené en position de transmission de couple par la poignée (37). La poignée (37) est en outre actionnable pour faire passer la pièce de verrouillage (34) de la position de verrouillage à celle de déverrouillage et vice versa. De plus, une liaison optique (29, 32) entre l'ensemble du pêne dormant (21) et un ensemble de verrouillage électronique de porte (23) est prévu.

Abstract: Driver's cabs of various widths have been equipped hitherto with different special built-in components, including a cupboard unit. Usually, a cupboard unit (behind the driver's seat) is used which has different depths depending on the width of the cabin. When used by two people, only one cupboard part is therefore available. Likewise, the heights of the built-in units are determined by the heights of the roofs. A multiplicity of individual components which are additionally necessary for the right-/left-hand drive version make production of cabins of different widths more expensive. According to the invention, a driver's cabin (1) with at least one cupboard unit (2) of modular-like or single component construction on the driver's side (5) is proposed, the cupboard unit (2) being equipped with a high front wall (4) which can be mounted both on the driver's side and also with inverted sides on the front seat passenger's side in the presence of a cupboard unit (2) which may be there. The cupboard unit (2) also comprises a side wall (8) with an upper recess component (11) and a lower recess component (10) which can be additionally provided or covered with modular-like built-in components. <IMAGE>

Abstract: A full access nonblocking one-sided multistage switching network, the first stage of which contains partial access switching blocks, comprises a reasonable number of used elements. Their terminals which can be connected to any other terminal of the block constitute the terminals of the switching network. The remaining terminals of the block are used for connections with the switching blocks of the next stage. The switching blocks (1 to 16) of the first stage are constructed of two triangular switches (1′, 1˝ to 16′, 16˝). The half of the terminals of the first triangular switch of the pair is connected with the half of the terminals of the second triangular switch of the pair, and these terminals constitute the terminals of the switching network. The remaining terminals of both switches in the first-stage blocks (1 to 16) are used for connections with the switches (18 to 32) of the next stage (17). 
     Such a structure of one-sided switching network, in which one of the stages is constructed of partial access switching blocks, enables to obtain considerable savings of the number of used elements.

Abstract: Apparatus for sorting metal bars by length, has a conveyor on which the bars are arranged longitudinally and conveys the bars both longitudinally and laterally. The conveyor has driven rollers (5) contacted by the bars. Pick-up means (31) pick up and convey laterally, with respect to said conveyor, ends of bars having a predetermined length, thus preventing the longitudinal movement of such bars while bars not of said predetermined length are conveyed longitudinally at least partly past said pick-up means (31) by said conveyor. To avoid increase capacity of the apparatus, and avoid wear, the rollers are oblique rollers (5) whose axis of rotation is at a non-zero angle to the lateral direction of the conveyor, these rollers being, over at least part of their axial lengths, circular cylindrical in shape.

Abstract: In an ophthalmic measuring apparatus a laser beam ( 1 ) is projected onto a selected spot ( P ) in the eye ( 30 ) and light scattered therefrom is received by a photoelectric converter and processed for ophthalmic measurement. The photoelectric converter is realised by an array of avalanche photodiodes ( APD1 to APD6 ) or by a photomultiplier ( 16 ) provided with a shutter module which comprises an array of liquid crystal elements ( 15′ ). Signals from the avalanche photodiodes ( APD1, APD2, APD5, APD6 ) or from the liquid crystal elements disposed at lateral positions are subtracted from signals from those at the central position ( APD3, APD4 ) to remove a noise component based on the light ( BG1, BG2, BG3 ) scattered from the portions surrounding the selected spot (P) in the eye (30).
