Inventor: MOELLENKAMP SIEGFRIED
IPC: E05B27/00

Abstract: The invention relates to a lock cylinder with tumbler pins, in which a baffle pin (109) or a plurality of baffle pins are provided at a particular angular spacing from a core pin or a plurality of core pins (107) in the lock case. Each core pin (107) can thus be assigned a particular baffle pin (109). The baffle pin or baffle pins (109) fall into the respective core bore (106) after a particular angular rotation of the core, if the rotation of the core is carried out by means of an unsuitable key or without a key. The cylinder core (99) is thereby blocked. Security is thus increased considerably. <IMAGE>

Abstract: The invention relates to a method and an apparatus for the continuous production of a metal strip (1) with dimensions close to its final dimensions. In this method, molten metal (6) is poured onto an endless revolving cooling belt (2) and solidified. To achieve substantially laminar deposition of the molten metal (6) on the cooling belt (2), the following steps are proposed:   - the molten metal (6) flows out of a distributor (5) through a narrow channel (7) of rectangular cross-section connected to the distributor (5), - the channel (7) is inclined relative to the horizontal (angle of inclination  alpha ), - the channel (7) emerges in a discharge opening (7) above the cooling belt (2), - the speed of the molten metal (6) flowing out is controlled by retarding the molten metal (6) flowing in the channel (7) by an electromotive force which counteracts that of gravity.   <IMAGE>

Abstract: The invention concerns a forming-gap arrangement in a twin-wire former of a paper machine. The twin-wire former comprises forming wires (10,20) operating one against the other, which forming wires (10,20) define a wedge-shaped narrowing forming gap (G) between them. The forming-gap arrangement comprises two opposite support members (40, 41), whose inner sides have been arranged as direct extensions of the inner sides of the lip walls (31,32) of the headbox that define the discharge duct. The support members (40,41) have been arranged to extend into the forming gap (G) as parallel to one another, so that the free ends (42) of the support members (40,41) are placed at direct proximity of, or in contact with, the forming wires (10,20). The support members (40,41) have a plate-like, isotropic or anisotropic, at least to some extent resilient construction.

Abstract: In packet-based networks (10), it is often desired to test communications between two specific stations (11, 12). This can generally be effected from a first one of the stations (11) by requesting the other station (12) to 'loop-back' a test packet sent from the first station. The first station (11), on receiving back the test packet, can thereby ascertain that not only is communication with the other station (12) possible, but it can also measure the round trip time. However, more complex characteristics of the transmission path between the stations (11, 12) are not ascertainable in this manner. The transmission of a predetermined sequence of packets permits such characteristics to be determined by observing the effect of the network (10) on the sequence considered as a whole. Thus by varying packet size in a sequence, characteristics such as bandwidth, propagation delay, queuing delay and the network's internal packet size can be derived. The use of bursts of packets enables buffer size and re-sequencing characteristics to be determined.

Abstract: The invention is a technique for the growth of single crystals of rare earth doped rare-earth orthosilicate crystals which may be used as the laser medium in solid-state non-semiconductor lasers. This type of laser has applications in electronics, communications, aerospace systems, and manufacturing technology where high optical output lasers are utilized. Of particular interest is the Y 2-x Nd x SiO₅ crystal, with x being up to 0.3, which may be efficiently pumped by a semiconductor laser, solid state non-semiconductor laser, a flashlamp or some other source of light radiation, and has been found to be operable at very high optical output. The rare-earth orthosilicate crystals are grown in accordance with this invention by a Czochralski technique from a molten mixture of constituent oxides in an inert atmosphere containing oxygen. Inclusion of oxygen in the inert atmosphere in concentration of from about 300 to about 9,000 PPM of oxygen resulted in substantial reduction in the density of light scattering defect sites and, thus, in substantial increase in the optical energy which may be applied to the crystal without causing substantial damage to the crystal in comparison to the crystals grown in an inert atmosphere containing less than 300 PPM, such as 200 PPM and less, of oxygen. Absorption of energy from the high optical flux present during the laser operation at these defect sites results in farther degradation of the laser crystal. Through selection of the O₂ concentration in the atmosphere in which the crystal growth is performed, the density of defects which produce light scattering has been significantly reduced. By application of the growth atmosphere composition control, optical damage thresholds have been increased by more than an order of magnitude.

Abstract: Poche (10) servant à collecter, à geler, à stocker, et à dégeler rapidement des fluides, et plus particulièrement du sang et des composants sanguins. Les couches avant et arrière (11, 12) de matière étanche aux fluides sont liées l'une à l'autre en périphérie (14) et constituent ainsi une poche (10) formant un réservoir. Les couches avant et arrière (11, 12) sont en outre liées entre elles en une pluralité d'endroits (60) situés entre les parties périphériques (14) pour restreindre la distance de séparation entre les couches avant et arrière. Les emplacements d'assemblages intermédiaires (60) sont disposés de façon à permettre un remplissage uniforme du réservoir. Un orifice (30) est prévu pour introduire un liquide dans le réservoir et pour le retirer. Quand un fluide est introduit dans le réservoir, les couches arrière et avant (11, 12) ne peuvent se séparer en raison de la pression exercée par le fluide et par les assemblages intermédiaires (60) entre les couches avant et arrière (11, 12); l'épaisseur de la poche (10) est ainsi restreinte. La distance entre les points les plus centraux à l'intérieur de la poche et les points correspondants situés le plus près de la partie extérieure de la poche est réduite au minimum, ce qui accroît le rythme auquel la chaleur est transférée dans ou en dehors du contenu de la poche. Le transfert de chaleur est ainsi considérablement amélioré, et le temps nécessaire pour geler ou dégeler le contenu de la poche est sensiblement réduit.
