Patent CA-2071155-A1 (CA)
Inventor: ENGDAHL GOERAN
IPC: H01H33/34
Filed: 1992-06-12
Abstract: An electric switching device according to the invention comprises two fixed contacts (1, 2) and one movable contact (3), referred to jointly as the main contact system. The main contact system is located in an oil-insulated cavity (13) enclosed in a housing (10), In its direction of movement, the movable contact has an extension in the form of a shaft (14). The shaft is formed with a hydraulic piston by which the movable contact is operated. The hydraulic piston is surrounded by a cavity in which a piston cavity (15, 16) is formed on each side of the hydraulic piston. The piston cavities are oil-filled. The movement of the shaft is determined by an electrically controlled directional valve (21).      The directional valve receives signals as to whether the electric switching device is to be opened or closed. At a given signal, the directional valve distributes a high pressure to the piston cavity that is to be enlarged. The electric switching device can be provided with an auxiliary contact mechanism which can be placed either in the fixed contacts and/or in the movable contact. The electric switching device is provided with a bistability mechanism comprising wedge pistons (45, 46) biased by means of springs (47, 48), said wedge pistons, in case of drop-out of pressure, locking the movable contact in the existing position via the shaft.

Title: Device for adjusting seat frame and back rest of chair of swivel type
Inventor: NEUMUELLER KONRAD
IPC: A47C1/032
Filed: 1992-10-16
Abstract: ABSTRACT OF THE DISCLOSURE    A pedestal supported chair such as a swivel type chair in which a seat plate carrier pivoted to a base member fixed to the pedestal  and  having  a  back rest  carrier  is  provided with adjustment  means  operable  over  range  of  user  weights  for adjusting a torsion spring mounted with its windings on the pivot by which the seat plate carrier is mounted to the base member.          First legs of the spring member engage the seat plate carrier and second spring legs are connected to a holder supported from the base member.   Rotation of a shaft passing through the holder moves the holder towards or away from the base member and results in greater or lesser tightening of the windings of the torsion spring to compensate in corresponding manner for the greater or lesser weight loadings which can be imposed on the seat plate carrier and on a chair back rest carrier when a user whose weight will be any one of such in a range of weights, sets a positioning relationship between the seat element and back rest and back rest intended to be that most comfortable to the user.

Filed: 1991-04-05
Abstract: A solution process, and a catalyst therefor, for the preparation of high molecular weight polymers of alpha-olefins viz. homopolymers of ethylene and copolymers of ethylene and C3-C12 alpha-olefins, is disclosed. The process is operated under solution polymerization conditions at 105-320°C. The catalyst is obtained from titanium tetrahalides, vanadium oxytriha-lides and organoaluminum compounds, in which an admixture of catalyst components is heat-treated at 180-250°C and subsequently cooled to a temperature of less than 150°C. Additional vanadium oxytrihalide is then added. The resultant ca-talyst solution is activated with an aluminum compound. The catalyst has good activity, showing superior activity to catal-ysts in which additional vanadium oxytrihalide is not added or added at temperatures above 150°C.

Title: Automatic chlorinating apparatus
Inventor: SENEFF WILLIAM L
IPC: C02F1/00
Filed: 1993-03-12
Abstract: ABSTRACT     A pressurized gas chlorinator is constructed in the form of a two-compartment pressurized container.   The lower container  is filled with a media liquid, such as hydrochloric acid (HC1). A pair of electrodes are located in the lower container beneath the surface of the media liquid, with one of the electrodes located at or near the bottom of the container and the other electrode located at or just below the top surface of the media liquid.  Electric current is applied to the electrodes to cause a breakdown of the HC1 into Hydrogen and Chlorine gas.  A floor member is spaced a short distance above the surface of the media liquid in the lower compartment, and has an opening in it.  This floor member comprises the bottom of the upper compartment; and gas is passed upwardly through the opening in the floor member into the upper compartment.          Side walls surround the opening, and transport liquid (typically, water) flows into and out of the upper compartment around the side walls to absorb the gases, which are under pressure in the upper portion of the upper container.  When the gas pressure drops, some of the transport liquid is permitted to pass over the top of the side walls to drop through the opening in the floor member to replenish the media liquid, which is constantly being depleted by means of the electrolysis action.  This prevents excess gases from being present in either the lower chamber or the upper chamber.

IPC: H04B10/291
Filed: 1991-11-20
Abstract: Réseau optique comprenant une fibre optique à base de silice dopée à l'erbium (30), dont la section est en forme de D. Le guide d'onde achemine des signaux d'information à 1,53 µm provenant d'une source de signaux (38) et les amplifie par pompage au moyen d'une source de pompage optique fonctionnant à 0,994 µm (36). Les signaux optiques sont prélevés du guide d'onde au moyen de coupleurs évanescents (32 et 34). Le guide d'onde (30) assure une amplification suffisante pour compenser au moins la perte de prélèvement du signal d'information due aux prises optiques. Le coeur du guide d'onde optique (30) est choisi de façon à réduire sensiblement le diamètre des points constitués par les signaux à la longueur d'onde de la source de pompage (36). On assure ainsi l'extraction préférentielle du signal d'information afin de laisser la source de pompage essentiellement libre d'obstacles pour le pompage des régions du guide d'onde amplificateur (30) qui sont au-delà de la prise optique.

Title: Two-stage helical oil separator
Inventor: WESTERMEYER GARY W
IPC: F25B43/02
Filed: 1993-08-18
Abstract: The present invention provides an improved oil separator in which the oil/refrigerant mixture is caused to flow through two different filter elements. Each of the filter elements is contained in a separate chamber within the separator. A valve assembly is also provided that selectively permits only oil to flow from the first chamber to an oil collection area in the second chamber. The valve assembly regulates the flow of collected oil to the collection area such that the oil/refrigerant mixture cannot escape from the first chamber except by flowing through the filter element of the second chamber. In one embodiment, the valve assembly can include an elongated oil drain extending from a first end adjacent to an oil drain aperture in a dividing wall separating the first and second chambers to a second, open end. A valve seat is formed on the second end of the oil drain. A ball valve element is provided for selective sealing engagement with the valve seat, and the ball valve element is biased toward engagement with the valve seat by a resilient member. In a preferred embodiment, the invention provides a multi-stage device for separating oil from a gas. The device includes a first chamber having an access opening and containing a first filter element. A second chamber is provided adjacent to the first chamber, and contains a second, replaceable filter element. A passage is formed in the first chamber that leads from the second chamber through the access opening in the first chamber, whereby the second, removable filter element can be removed from the second chamber through the access opening via the passage. The second, replaceable filter element may be removed from the separator by means of an elongate handle member having a first end secured to the replaceable filter element; and a second end disposed adjacent to the access opening in the first chamber.
