Title: Pompe volumetrique a palettes a debit variable a flux constant
Inventor: JERONYMO CARLOS
IPC: F04C14/22
Filed: 2001-06-29
Abstract: Une pompe à capacité variable comprend un corps et un rotor rotatif situé dans le corps. Le rotor comporte des fentes radiales dans laquelle se logent des palettes coulissantes ou des ailettes de rotor, lesdites palettes étant poussées vers l'extérieur par la force centrifuge pour se trouver en contact avec la surface interne d'une couronne à cames située autour. La couronne à cames est entourée à une extrémité par une chambre de pression comprenant un piston soumis à une pression hydraulique et à l'autre extrémité par un ressort supporté par un siège. Le fait de réguler la pression distribuée à la chambre de pression permet de changer la position de la couronne à cames par rapport au rotor afin de varier automatiquement la cylindrée de la pompe en réponse à une différence de pression au niveau d'un limiteur, ceci ayant pour effet de réguler le débit de sortie de manière constante sur une plage de régimes définie.

Patent CA-2010339-A1 (CA)
Inventor: MUNDUS FRIEDHELM
IPC: B31B50/86
Filed: 1990-02-19
Abstract: An apparatus is disclosed which serves to apply reinforcing slips provided with a glue coating to a web which has transverse perforation lines, preferably to a web that consists of bags, which are joined at the trans-verse perforation lines, comprising means for tearing from the web the sections or bags which are joined at the transverse perforation lines. A belt conveyor is provided, which consists of spaced apart endless conveyor belts, which are trained around receiving-end belt pulleys. A conveyor roller is disposed above said receiving-end reversing pulleys and urges the incoming web against the reversing pulleys. The conveying belts of the upper course are supported by a supporting roller, which is spaced behind the receiving-end reversing pulleys by a distance which is smaller than the spacing of the transverse perforation lines of the web. The supporting roller constitutes a backing roller for cooperating with a rotating segment, which has a cylindrical peripheral surface and serves to hold and transport the reinforcing slips. The radius and the surface speed of the peripheral surface of said segment are so selected in dependence on the length of the sections of the web that said segment urges each section of the web against the backing roller and causes a portion of each section of the web to be in rolling contact with the backing roller between two conveying belts. The surface speed of the segment and of the backing roller exceeds the conveying speed of the belt conveyor so that a slip is stuck on each section and each section is torn from the web.

Patent CA-2011563-A1 (CA)
IPC: H02J7/14
Filed: 1990-03-06
Abstract: ABSTRACT OF THE DISCLOSURE         A power conversion system is disclosed in which a direct current is taken out of an AC power supply of variable frequency and variable voltage through a PWM converter in such a manner that in a region of low source voltage, the converter input current is limited to a predetermined value to maximize the DC power taking the voltage drop of the power supply into consideration with the power factor of "1" of the power supply, and when the current reaches an allowable maximum, it is limited to that value.  In a region of high source voltage, on the other hand, the quadrature component of the input voltage applied to the source voltage is controlled preferentially in a manner to control the converter input voltage below a predetermined value, thus making it possible to secure the maximum power available from the converter over the entire range of operation.  If a battery is connected to the DC side, a cooperative operation is made possible while the battery is charged properly.

Title: Bundling and stacking machine
Inventor: TSCHESCHE MARTIN
IPC: B65B27/10
Filed: 1990-11-23
Abstract: BUNDLING AND STACKING MACHINE             ABSTRACT OF THE DISCLOSURE        A  machine  forms pairs of elongated articles, bundles  the  pairs,  and then stacks the bundles.  A receiver  and  inverter function together to hold one of  the  articles  in  place and then invert a second article  onto  the  first  article to form an article pair.    A  number  of  the  article pairs, typically about  five  pairs,  are  stacked  on a vertical lift that  controllably  moves  downwardly  as  additional pairs  are  added.    An  optical  sensor  senses the position   of  the  top  of  the  topmost  pair,  and controls  the  position  of  the  lift  so  that  the measured  top  is  at  a  preselected  position  that permits  yet  another pair to be added to the bundle. After  the bundle  is  formed,  it  is pushed onto a conveyor  where  a  cradle  turns the bundle sideways through  90 degrees.  At an intermediate point of the conveyor,   a  retractable  holding  stop  halts  the movement  of  the  bundle to permit a banding machine to   band  the  bundle  together  with  one  or  more straps.    A stacking unit picks up the banded bundle from   the  conveyor  and  moves it  to  a  stacking location,  where it is stacked together with a number of  other  bundles.    The stacking unit makes use of proximity  switches  to  control  the  horizontal and vertical  movement  so  that engagement of the bundle and  its placement onto the proper location are fully automated.
