Inventor: AOSHIMA YASUSHI
IPC: B62M27/02
Filed: 1991-01-14
Abstract: An air intake system for a snowmobile which comprises an internal combustion engine having an induction system.  A body is provided which cooperates in defining an engine compartment wherein the engine and induction system are contained.  This body has an opening for inducting air from the atmosphere and is in communication with a passageway which defines an air flow path from the opening to the induction system so that air flows from the opening to the induction system without accumulating in the engine compartment.  A filter element is positioned between the opening and the induction system across the air flow path such that the air flows in a generally upward direction through the filter element.  The filter element not only prevents snow and ice from being sucked into the induction system but also prevents these elements from clogging the filter, while still allowing for adequate air flow to the induction system.

Title: Viscous fluid pressure-feed apparatus
Inventor: HOYA TAKESHI
IPC: F04B43/06
Filed: 1991-01-21
Abstract: Abstract of the Disclosure:    This invention relates to a viscous fluid pressure-feed apparatus which feeds and drains a slurry of a highly viscous fluid in a casing to a filter press, or the like inside, or outside, a flexible film by pressurizing the swellable flexible film through the feed/drain operation by an oil pressure generation apparatus outside, or inside, the flexible film which is supported by the casing.          Particularly, a mechanical press-in apparatus such as a screw feeder is disposed at a suction port of the viscous fluid into the flexible film disposed in the casing so as to operate in synchronism with expansion and contraction of the flexible film and to supply compulsively the slurry having a high viscosity from a slurry tank.  Furthermore, a gas reservoir chamber is added to the casing and a gas exhaust valve is disposed in the gas reservoir chamber.  The interior of the casing is sealed through a valve disposed at an outflow port of the press-in apparatus and separation and exhaust of the gas existing in mixture in the slurry of the viscous fluid can be made freely through the opening or closing operation of the exhaust valve. This, the pressure-feed apparatus of a viscous fluid of the invention can make high pressure pressure-feed of the viscous fluid.

Title: Lift arm lock down apparatus and method
Inventor: DUBE CLAUDE
IPC: E02F3/38
Filed: 1991-01-29
Abstract: ABSTRACT        A lift arm lock down apparatus for a load lifting vehicle is described.  The vehicle has a vehicle body and a lift arm or boom rotatable between a raised and a lowered position about a horizontal pivot on the vehicle body.  The lift arm lock down apparatus includes a lock having first and second cooperating lock members for selectively locking the lift arm to the vehicle body in the lowered position.  The lock members are respectively mounted on the lift arm and the vehicle body.  At least one lock member is movable by an appropriate manually or automatically operated mechanism between an unlocked position permitting tilting of the lift arm and a locked position where the lock members are releasably interconnected when the lift arm is at the lowered position.  The lift arm lock down apparatus prevents accidental lifting of the lift arm when the operator is entering or exiting the operator's compartment and may be used as a theft deterrent when the lift arm is locked in a lowered, ground engaging position.

Patent CA-2037847-A1 (CA)
Title: Capacitive fluid level sensor
Inventor: HART JOHN R
IPC: G01F23/26
Filed: 1991-03-08
Abstract: ABSTRACT OF THE DISCLOSURE      A device that determines liquid level or volume by means of charging a plurality of capacitors in sequence.  Each capacitor is charged for a fixed time interval.  The voltage level obtained is a function of the liquid level and is compared with a known voltage to obtain an output signal that can be used to represent liquid depth.  The capacitors are formed by two concentric tubes, one inside the other in a spaced relationship.  The tubes reduce the effect of sloshing in the tank, resulting in a more stable reading.  To measure volume or level in an irregular shaped tank, the capacitors can be arranged in a non-linear manner.  The device has no moving parts to wear out and thus results in higher reliability and longer life.     7633o

Patent CA-2047262-A1 (CA)
Title: Message network monitoring
Inventor: DOLAN FRANCIS
IPC: H04L12/26
Filed: 1991-07-18
Abstract: Abstract Message Network Monitoring Fig. 4 A switching network consists of end units between which messages flow.   The end units are connected together directly (via LANs) or via common switching nodes through level O (LO) links; the nodes are connected together via level 1 (L1) links; and the nodes are grouped into areas which are connected together via level 3 (L3) links.    A message entering a node has its destination area code (23, AREA) compared with the node's area (in 26), and an area/port table 28 or an end unit/port table 29 is used to look up the output port to the end unit, next node in the area, or next area.   Logic circuitry 35-48 determines the incoming and outgoing levels (LO->LO, LO->L1, ... L2->L2), and the combination is logged (at 30) together with certain details of the message.    Messages are thus monitored - i.e., their passage is recorded - when they cross levels in the hierarchy. Thus  provided  the  network  is  "well-behaved",  messages  are accurately counted and categorized according to the distances which they travel through the network.

Title: Feedback system for load bearing surface
Inventor: GROSS CLIFFORD M
IPC: B60N2/90
Filed: 1991-11-26
Abstract: An electronic system for adjusting a load bearing surface such as a chair or bed to provide a desired level of comfort comprises an array of pressure sensors located within the load bearing surface. The pressure sensors generate data indicating the actual distribution of pressure exerted by a user on the load bearing surface. An electronic processor processes the data generated by the array of pressure senors. The processor compares the fraction of total load exerted on each of a plurality of regions of the load bearing surface with a desired range for each region. If the fraction of total load for any region is not within the desired range, a servo-mechanism is activated to change the shape of the load bearing surface so that the fraction of total load on each region is within the desired range, so as to provide a desired level of comfort to the user.
