Patent CA-2124872-A1 (CA)
Inventor: OTTO JOHN G III
IPC: E05B47/00
Filed: 1994-06-01
Abstract: A lock assembly for locking a door to a frame element, comprising a rotatable locking element and a lock-ing  rod  connected  to  the  rotatable  locking  element. Rotation of the locking element in one sense results in the locking rod moving toward a first side of the frame element and rotation in the other sense results in the locking rod moving away from the first side of the frame element.  The lock assembly also comprises a pin having a first end and a second end, wherein the first end selectively engages the rotatable locking element at an engagement position so that the locking element is prevented from rotating.  The lock assembly comprises a pin actuating mechanism for moving the pin from the engaged position to a disengaged position wherein the pin does not engage the locking element.  The lock assembly further comprises a rotatable cam having a striking surface to strike the second end of the pin when the pin is at the disengaged position causing the first end of the pin to contact and ride along the surface of the rotatable locking element as it rotates.

Abstract: Abstract of the Disclosure A connector assembly for connecting two cylindrical members in which two connector members are respectively connected to the cylindrical  members.    The  respective  end  portions  of  the connector members are adapted to interlock to prevent relative movement of the connector members, and therefore the cylindrical members, in a first plane.  A sleeve extends over at least a portion of the connector members to prevent relative movement of the latter members, as well as the cylindrical members,  in a second plane perpendicular to the first plane.  The sleeve is lockable in its preventing position and can be easily released by a simple rotation of the sleeve.

Abstract: A method for recovering fluids such as crude oil, associated solution gas, formation water, injected water, natural gas and other gases, and natural gas liquids, from a hydrocarbon producing reservoir or formation in which fluids collected in one or more substantially horizontal wells are routed to the surface through a substantially vertical wellbore.  The method may be employed in connection with entirely new well systems, by drilling a vertical wellbore to intersect or penetrate the producing formation in close proximity to one or more existing horizontal wells, or by drilling one or more horizontal wells to intersect or terminate in close proximity of an existing vertical wellbore.  Preferably, the vertical wellbore extends to a depth greater than the depth of intersection with the horizontal well or wells, forming a sump for the collection of fluids.

IPC: C23C16/44
Filed: 1993-06-11
Abstract: 2136863 9326038 PCTABScor01 A semiconductor wafer processing apparatus (10) is provided with a susceptor (40) for supporting a wafer (44) for CVD of films such as blanket or selective deposition of tungsten or titanium nitride, and degassing and annealing processes. Preferably, a downwardly facing showerhead (35) directs a gas mixture from a cooled mixing chamber (30) onto an upwardly facing wafer (44) on the susceptor (40). Smooth interior reactor surfaces include baffles (90, 101, 102) and a susceptor lip (162) and wall (130) shaped to minimize turbulence. Inert gases flow to minimize turbulence by filling gaps in susceptor structure, prevent contamination of moving parts, conduct heat between the susceptor and the wafer, and vacuum clamp the wafer to the susceptor. A susceptor lip (162) surrounds the wafer (44) and is removable for cleaning, to accommodate different size wafers, and allows change of lip materials for different processes, such as, one which will resist deposits during selective CVD, or one which scavenges unspent gases in blanket CVD. The lip (162) smooths gas flow, reduces thermal gradients at the wafer edge. The susceptor design reduces heat flow from the susceptor to other reactor parts by conduction or radiation.

Title: Method of rinsing in a vertical axis washer
Inventor: MUELLER DALE E
IPC: D06F35/00
Filed: 1995-02-16
Abstract: A method of rinsing in an automatic washer having an imperforate wash tub, a perforate wash basket disposed within the tub and rotatable about a vertical axis and a bottom plate disposed within the lower portion of the wash basket and mounted for wobbling motion.  A motor is selectively interconnected with the basket and bottom plate for rotating the basket and the bottom plate together and for wobbling the bottom plate relative to the wash basket while the basket is held stationary such that the clothes items are agitated within the wash basket.  A controlled rotation device is provided for driving the bottom plate in a wobbling motion while rotating the bottom plate, at a reduced rate, within the bottom of the wash basket.  A liquid level control system is also provided for supplying an optimum quantity of wash liquid into the tub wherein the clothes items within the wash basket are washed in an out-of-water wash process rather than being submerged.  A recirculation system operates to pump wash liquid from a sump, disposed in the bottom of the tub, through a recirculation line and onto and through the clothes disposed within basket.  The method of rinsing includes adding rinse liquid into the wash basket and recirculating the rinse liquid over the clothes items while driving the bottom plate in a nutating movement.   Nutating movement describes the movement of the bottom plate wherein the bottom plate is slowly rotated within the wash basket while being driven in a rapid wobbling motion.  In this fashion, the clothes are repeatedly moved under a spray pattern of rinse liquid while being jostled and flexed for achieving the desired excellent detergent and soil removal during rinse.          In a second embodiment, the step of slowly rotating the wash basket for moving the clothes under a spray pattern of rinse liquid is combined with a step of wobbling the bottom plate for agitating the clothes while spraying rinse liquid onto the clothes items.
