Patent CA-2113719-A1 (CA)
Inventor: DESJARDINS RENE A
IPC: B64C27/45
Filed: 1992-07-31
Abstract: A tail rotor (8) for a rotary wing aircraft is located in a laterally directed duct (9) located at the end of a tail cone (7) extending rearward from the aircraft cabin and at the base of an empennage (5) extending upward from the duct. The rotor includes a rotor shaft (50) driveably connected to a power source; a rotor hub (10) connected to the rotor shaft (50), a rotating control shaft (64), a stationary control shaft (124), and an actuator (132) connected to the stationary control shaft (124) for moving the rotating control shaft (64) axially.      The rotor hub (10) includes rotor arms (12) each supporting a pitch shaft-blade spar (18, 16) assembly for pivotable movement about a pitch axis. A pitch beam (96) supports flexures (94), each connected to a pitch arm (80) offset laterally from the associated pitch axis. The flexures (94) driveably connect the pitch arms (80) to the pitch beam (96) and transmit pitch control motion to the blades (14) as the pitch beam (96) moves along the rotor axis. Pitch bearings (20, 22), on which the pitch shafts (18) turn about the pitch axes, are supported on a rotor hub shell (46) fixed to the rotor hub (10).

Title: Modular dispenser
Inventor: SHAW TERESA M
IPC: B67C11/04
Filed: 1994-02-14
Abstract: A modular household dispenser for fluent solids or liquids includes a rectangular casing for mounting on a wall or beneath a cupboard, and a hopper slidably mounted in the open front end of the casing. The hopper includes an inverted frusto-pyramidal bottom, the dispensing lower end of which is closed by a valve. Springs bias the valve to a closed position, whereby the valve automatically closes following a dispensing operation. During use, the hopper is slid outwardly to a dispensing position. A small container is located beneath the valve in the dispensing position for receiving any overflow. Upon completion of a dispensing operation, the hopper is slid inwardly to the storage or non- use position. The entire structure is relatively simple, compact and easy to install and use.

Title: Method and apparatus for controlled spray etching
Inventor: KETELHOHN KARL F G
IPC: H05K3/06
Filed: 1992-10-30
Abstract: A method and apparatus (10) is provided for controlled spray etching, in which panels, such as printed circuit boards (P) are delivered through an etching chamber (10), to have a spray etchant sprayed generally on upper and lower surfaces of the panel (P). The spray is controlled such that a reduced amount of etchant is provided on the perimeter surface (51, 52) portions of the panel, relative to the central surface (71) portions of the panel (P), transversely of the path of travel of the panels (P) through the etching chamber (10). The spray may be varied in amount, preferably by varying the pressure at different locations transversely of the chamber; the spray longitudinally through the chamber, may vary, to spray leading (51) and trailing surface (52) portions of the panels (P) a lesser amount than central portions (71) of the panels (P), measured longitudinally. The control of the spray of leading (51) and trailing surface (52) portions of the panel (P) may be facilitated by one or more sensors (50, 50') that control an intermittent discharge of spray etchant near the inlet (15) to the etch chamber (10).

Title: Cooling unit and drain case for air conditioners
Inventor: HASEGAWA ETSUO
IPC: F24F13/22
Filed: 1994-05-11
Abstract: A drain case is disposed between the bottom wall of a unit case and the lower end of refrigerant passage pipes of a stacked type refrigerant evaporator. The drain case is W-shape in cross section, and comprising two pieces of outside inclined walls contacting the side ends of two pieces of tank parts formed at the lower end side of the refrigerant passage pipes, a chevron type protruded wall contacting a recessed part formed at the bottom end of the part between the adjacent two pieces of tank parts and inside inclined walls having a drain hole. In this arrangement, the condensed water flows from the side ends of the two pieces of tank parts and the part between the two pieces of tank part into the lower ends thereof reaches the two pieces of outside inclined walls and protruded wall of the drain case before reaching the bottom end of the two pieces of tank parts, and then is efficiently drained therefrom.      Localized corrosion that may occur at the lower end part of refrigerant passage pipes is prevented by not allowing the condensed water to stay at the lower end side of the refrigerant passage pipes.

Title: Portable computer system for resolving conflicts between the portable computer system and an expansion base unit
Inventor: BELMONT BRIAN V
IPC: G06F1/16
Filed: 1995-04-28
Abstract: A notebook computer system for docking to a motorized expansion base unit.  Before the actual docking event occurs, the notebook computer system communicates with the expansion base unit via a sense signal, which is provided by the notebook computer to indicate the power state of the notebook computer.  If the expansion base unit determines that the notebook computer is in a proper state for docking, it activates its motor to load the notebook computer.  Once docked, the notebook computer runs a resource conflict check routine to determine if resource conflicts occur.  A fatal conflict occurs when the resource requirements of bus devices connected to the expansion base unit conflict with the resource requirements of a video controller or hard disk drive connected to the notebook computer.  When such a fatal conflict occurs, the notebook computer issues a software eject request to expansion base unit.  In response, the expansion base unit undocks the notebook computer.  A non-fatal conflict occurs when the resource requirements of the expansion base unit devices conflict with the resource requirements of PCMCIA cards inserted into the PCMCIA slots of the notebook computer. Unlike the case of a fatal conflict, the notebook computer responds to a non-fatal conflict by disabling the offending devices in the expansion base unit.
