Abstract: White metal bearing alloy is applied to a bearing surface of a structure by loading the surface with a covering of flux, then rendering the flux molten by heat application, then progressively displacing the molten flux layer on the bearing surface with a moving body of liquid white metal. The resultant product is thereafter cooled. With this method atmospheric influences on the bearing surface are excluded and accordingly a tin interface layer is not required.

Abstract: A plurality of phase insulators are inserted in the cavities of the stator of a dynamo-electric machi­ne by means of an insertion device which includes a plurality of guide blades (8) displaced circumferen­tially around a central axis (9) and an insertion member (10) slidable between the series of guide blades (8) and having a circumferential series of axial grooves in its outer surface in which the various blades (8) are engated. The insertion member (10) is disposed initially in a rest position in which it allows a phase insulator to be positioned above the guide blades (8), after which it is moved to an oper­ative position so as to cause the phase insulators to slide along the guide blades (8) and to be inserted in the cavities of the stator. Before the phase insula­tors are disposed above the guide blades (8) at least some of them are moved from their normal operative positions to positions spaced radially towards the outside in which the arrangement of the phase insula­tors above the guide blades (8) is particularly simple so as to enable this to be carried out by automatic assembly equipment as well.

Abstract: Pour la commande d'un système de freinage avec régulation du dispositif antiblocage et/ou du glissement, on mesure et on analyse les grandeurs (DELTAtEV, DELTAtAV) qui déterminent la pression au niveau des freins (10, 11) agissant sur les roues. Les grandeurs ainsi mesurées permettent d'obtenir par intégration un modèle de pression au niveau des roues (p(t)) qui reproduit par approximation la variation de pression au niveau des freins (10, 11). Le signal de sortie de l'intégrateur (20) est renvoyé dans la logique de régulation (16) et analysé pour la régulation du glissement ou la commande de la pression de freinage. Dans l'intégration, il est tenu compte des courbes caractéristiques de hausse et de baisse de pression (pA, pE) et des conditions initiales (21) qui reproduisent la pression initiale lors de la mise en service de la régulation.

Title: An improved set point control circuit for an infrared gas analyzer.
Inventor: ROGERS RAYMOND EARL
IPC: G01N21/31
Filed: 1989-04-14
Abstract: An arrangement for ensuring the stability of the set point for a gas analyzer is disclosed. The set point control circuit utilizes an amplifier which is alternately switched between a reference voltage and a sensor signal to provide a signal to a processor representing the reference signal and the sensor signal. The processor compares the two signals and adjusts the heater associated with the sensor to provide a stable set point for the gas analyzer. The arrangement eliminates the need for precision resistors within the set point control circuit and therefore significantly reduces the cost of the circuitry.

Abstract: Le procédé décrit sert à surveiller l'état de fonctionnement d'une machine, tel que notamment une machine comprenant deux pièces mécaniques rotatives fonctionnant à des vitesses de révolution différentes et travaillant en coopération mutuelle. Des spectres de vibrations détectées sont comparés avec des spectres calculés théoriquement et les crêtes des spectres respectifs sont appariées entre elles. On attribue à chaque appariage ou assignation un poids de réglage, qui est spécifique pour une pièce mécanique donnée et qui augmente avec l'amplitude de la crête et décroît avec la distance des fréquences entre les crêtes. Les poids de réglage sont additionnés pour former des poids pouvant être attribués à la pièce mécanique respective. Les poids des pièces mécaniques forment des vecteurs de poids et une classe de référence est constituée sur la base de plusieurs vecteurs de poids obtenus pendant un fonctionnement normal. Chaque nouveau vecteur de poids est comparé à la classe de référence et on détermine ensuite si la différence dépasse une valeur de dispersion statistique prédéterminée.

Abstract: In a busbar, a carrier (10) has a U-shaped slot (11) into which there is inserted in a positively locking manner a U-shaped insulating part (5), whose U-limbs in the inserted state fix a flat, metallic bar part (1) which in this case rests against the centre limb of the insulating part (5). In order to ensure secure retention of the insulating part (5) in the slot (11), the U-limbs of the insulating part (5) are connected in a hinged manner to its centre part. In the non-inserted state, the insulating part (5) is flat. For insertion into the slot (11), the U-limbs are pivoted towards one another so that, in the inserted state, they latch in the slot (11) sprung away from one another. <IMAGE>

Abstract: An apparatus for thermostating the mobile phase in a liquid chromatograph comprises an ingoing capillary (1) connected with its one end to the injector of the chromatograph and with its other end to the inlet of the chromatographic column (3), and an outgoing capillary (2) connected with its one end to a detector and with its other end to the outlet of the column (3). The column (3) is arranged in thermal contact with a receiving piece (7) which can be brought to a desired temperature by a temperature control unit (13). The ingoing and outgoing capillaries (1,2) are arranged in thermal contact with each other along a contact region (4) such that the liquid leaving the column (3) at an elevated temperature gives off a large part of the heat which it transports, thus avoiding the disturbing heat transport to the chromatographic detector which would impair the measuring accuracy. At the same time, the liquid flowing to the column (3) is pre-heated by the liquid leaving the column, leading to a reduction of the required heating power.

Abstract: The object of the invention is to miniaturise a cutting tool of the type as defined in the preamble and in addition to design it in such a way that the cutting tip can be adjusted both radially and axially with respect to the tool axis so that the tool is also suitable for the machining of blind bores and stepped bores. To achieve this object, the arrangement of pressure members (50), in particular balls, is proposed which can be displaceably mounted in bores (52) of the cutting tip (18, 20) and can be pressed by one allocated adjusting screw (64) each to the outside against supporting walls (58, 60) of the basic tool body (10). The cutting tip (18, 20) is conveniently pressed against the bearing surface (12) on the basic tool body (10) by a clamping screw (30) which passes through it and is provided with a head (34). The preferred field of application is complete tools for the high-speed machining of internal and external bores with rotating tool. <IMAGE>

Abstract: The invention relates to a longitudinally adjustable upper guide 5 for a three-point coupling device. The upper guide has a connecting eye 13 with threaded shaft 15 and a coupling hook 7 with threaded shaft 14. Both are accommodated in threaded holes of a sleeve 8. The threads run in opposite directions. An actuating lever 24 and a retaining pawl 29, which can be swivelled partially independently of this, are provided in order to achieve a locking position or a disengaged position of the coupling hook 7 in relation to the sleeve 8. Due to the fact that the spring-loaded retaining pawl 29 can be swivelled from the disengaged into the engaged position independently of the actuating lever 24, no clamping forces can be exerted on the thread.

In addition, carrying members (12) of the slabs (3) can rest on the supporting members (29). By pivoting the slab (3) about the longitudinal axis of the supporting member (29), the slab can be lifted out in an inclined position. Located between mutually opposite slab edges of slabs (3) are interspaces (5, 6) which, together with slots (4) in the slab corners, permit reception of a securing element (8). By displacing the latter, the slabs (3) can be individually released and thus lifted out. A mounting system for building facades is thus provided, which enables optional individual facade slabs to be removed from the building facade. <IMAGE>
