Patent CA-2472453-A1 (CA)
Title: Vacuum cleaner
Inventor: COBURN ERIC
IPC: A47L9/00
Filed: 2004-06-25
Abstract: A vacuum cleaner 2 has a housing 4 having primary air outlets 20 defined in a bottom surface of the housing 4 to direct air downwardly and rearwardly of the housing. A fan 26 draws dirty air into the inlet 38, through a filter and most of the filtered air passes out of primary outlets 20. As a result, the air is not vented on to the face and hands of the user, and at the same time avoids disturbing dirt on the surface to be cleaned. A small amount of the air passes between the clamshell halves 10, 12 that make up housing 4, and out of the secondary outlets 28 in the side surfaces of the body portion 6. This air is used to cool the motor, but the rate of air flow out of the secondary outlets is insufficient to cause irritation to the user.
Patent CA-2472819-A1 (CA)
Title: Rotator which limits rotor rotation
Inventor: JONSSON ANDERS
IPC: E02F3/36
Filed: 2003-01-17
Abstract: The invention relates to a rotator (10) for jib-carried tools (1), for example tree working units, wherein the rotator (10) includes a stator (20) and a rotor (30), wherein the rotator (10) is connected to a tip (2) of the jib or arm (3) and to the tool (1). The rotator (10) has or includes in its surroundings means (70, 71) for determining the relative position of rotation between rotor (30) and stator (20). The means for determining the relative position of rotation comprises a pulse emitter (70) and a number of pulse generating elements (71), such as grooves or teeth. Limitation of the angle through which the rotator (10) can turn and control of the direction of rotation prevents, for instance, hoses and/or cables (7) from twisting or rotating away from their respective connections, while enhancing the extent to which automation can be achieved at the same time.
