Abstract: Un silencieux (12) pour un moteur (10) entraîné par de l'air comprimé possède des première et seconde parois (28, 34) extrêmes mutuellement opposées reliées par quatre parois latérales (30). Un tampon d'un matériau (52) d'absorption du son constitué en feutre de polyester SAE No. F-7 est contenu dans le logement (26) du silencieux. Un orifice (42) d'entrée au centre de la première paroi extrême permet l'entrée des gaz d'échappement dans le volume intérieur (32) du logement (26) du silencieux. Une série de dépressions (44, 46) dans la première paroi extrême (28) permet de disperser les gaz d'échappement sur une première surface plane (54) du tampon en matériau d'absorption (52) du bruit. La porosité de ce matériau (52) d'absorption sonore permet aux gaz d'échappement ainsi qu'à la graisse, l'huile ou l'eau transportés par les gaz d'échappement de passer au travers du tampon. Les gaz d'échappement sortent par une seconde surface plane (56) du tampon au niveau de la seconde paroi extrême (34) du logement (26) du silencieux et sont refoulés du volume intérieur (32) du logement (26) du silencieux au travers d'une pluralité d'ouïes ménagées dans la seconde paroi (34) du logement (26) du silencieux. Le silencieux est compact, de taille réduite et atténue de manière appropriée le bruit de l'échappement d'un moteur à air comprimé sans pour autant contraindre ou freiner l'écoulement des gaz d'échappement au travers du silencieux.

Abstract: A method and a device for monitoring direction indicators flasher lamps of a vehicle trailer (202) is proposed, in which 
 
  - a flasher unit (214) is provided for generating fixed clock frequencies, which can be switched over as a function of deviations of the load connected to it from its nominal load, when a direction indicator signal switch (215) is switched on and 
  - the aforesaid monitoring is performed without switching over of the flasher unit (214) to "trailer mode" - with an increased nominal load,
 in that one of the flasher lamps (208, 209) of the towing vehicle is disconnected from the electrical load of the flasher unit (214) when the trailer (202) is connected electrically and one of the flasher lamps (208, 209) of the trailer (202) which lamps are to be switched on and are operated with the clock of the flasher unit via a separate voltage supply fails. 
 
<??>By virtue of the lamp failure which is simulated in this way, the frequency generated by the flasher unit (214) is switched over for the immanent generation of a control signal to the vehicle driver. 
<??>Because the disconnected flasher lamp is however actually intact, it can continue to be operated via an auxiliary switching device, specifically preferably at the automatically switched-on frequency of the flasher unit which is provided when a flasher lamp (208, 209) of the towing vehicle (201) fails. The vehicle driver therefore clearly recognises from the visual indication that a trailer flasher lamp has failed.

Abstract: A self-adaptive stacker (30) comprised of infeed and stacking sections (100;200) whose movement is coordinated to provide interception of the signature stream (34). The infeed conveyor section (100) "Vees" the incoming signature stream (34) through the use of rollers (40,42) of different diameters mounted upon straight, spaced, parallel shafts. A microprocessor (400) utilizes a signal, representative of the infeed conveyor speed, together with a signal from a signature counter (164), to track the movement of each signature and thereby its arrival at the intercept position. Low armature inertia motors (172) drive the three axes, (stacking section (200), the turntable (302) and the ejectors (303,304) to provide rapid starting, acceleration, deceleration, and stopping at selected positions. These motors are controlled to interact in real-time in order to adapt the three axes to the rate of the incoming signatures (34). The movement of the signature carriers (220) is altered, when necessary, due to speed changes of the signature stream. A sensor located at the intercept ready position detects the passage of a signature carrier (220) to initiate acceleration of the signature carrier (220) by an amount which is a function principally of signature thickness, velocity and separation distance to control the amount of acceleration required to move the carrier (220) beneath the first signature of the next stack to be formed. The load current of the stacker motor (208) is monitored to detect the occurrence of a jam which condition is prevented from damaging the stacker section conveying assembly by halting and then reversing the stacker section motor (208) during a predetermined short time interval. Chain tension springs (212) allow the chain to yield for a period sufficiently long to permit the motor (208) to be halted and reversed before the stacking section (200) (i.e., drive chains, sprockets, etc.) can be damaged. A turntable section (300) forms compensated bundles by rotating a platform (302). A pusher assembly is mounted beneath the rotatable turntable platform (302) and includes pusher bars arranged by linkage members (346-349) to move precisely along the path of the drive chain to enhance monitoring, control and movement of the push rods (303,304). A sensor senses the passage of a push rod (303) to detect the initial movement and subsequent thereto the arrival of a push rod (303) to the home position.

Title: Axial thrust compensation for centrifugal pumps.
Inventor: HEUMANN ANTON
IPC: F04D29/22
Filed: 1991-07-19
Abstract: The invention concerns a device for fully compensating the axial thrust in centrifugal pumps with a first device which brings about a hydraulic compensation of the axial thrust with the aid of a pressure difference generated by the impeller of the centrifugal pump and a second device which takes up the remaining axial thrust when the pressure head is inadequate for the operation of the first device. In order also to overcome the overload region which can be a problem in axial thrust compensation without using an additional back-up bearing, the invention provides for a second compensating device, also hydraulic, which brings about an increase in pressure in the pressure side of the lateral impeller space when the pressure head falls below a predetermined value, by which this device assumes the compensation of the axial thrust at a time when axial thrust compensation dependent on the pressure differences between the impeller intake and discharge can no longer act satisfactory.

Abstract: A conveyor belt for endless conveyor belt systems is laid in tight curve radii because the belt and the guide bar, which is attached to the underside of the belt, consist of highly elastic rubber. The belt is reinforced by preferably diagonally placed fabric inserts and can be pre-stretched in the longitudinal direction by means of a traction beam attached only at individual points so that it can do an optimum job in performing its transport function. The reversing rollers and the roller blocks are divided or are made up of individual units in order not to influence the guide bar, which runs in the middle, during the overrun. In this way, the necessary drive forces can attack at many corresponding places depending on the curve radius, without the conveyor as a whole, with a length of 100 meters and more, being subject to the so-called flip-arc effect. Instead, the curvilinear, decentrally powered conveyor belt is driven uniformly and is fed simultaneously, while one can achieve a high conveyor output also in the transfer area by means of corresponding troughing.
