Patent CA-2000818-C (CA)
Inventor: TSUCHIHASHI AKIRA
IPC: B25J3/04
Filed: 1989-10-16
Granted: 1994-02-01
Abstract: ABSTRACT OF THE DISCLOSURE          A master slave manipulator system includes a master arm having six or more axes of motion and a jointed slave arm having six or more axes of motion. The master arm has an arm body and a wrist assembly connected to the arm body.  The wrist assembly of the master arm is constructed such that a space having predetermined dimensions in X, Y and Z directions is formed around a gripper by disposing a pitch- axis, a yaw-axis and a roll-axis thereof outside of the space and by directing output axes of the pitch-axis, the yaw-axis, and the roll-axis toward the gripper.  The slave arm has a wrist assembly which is constructed such that a pitch-axis, a yaw-axis and a roll-axis are accom-modated within a space having predetermined dimensions in X, Y and Z directions which are different from those of the wrist assembly of the master slave by shortening connecting members between the pitch-axis, the yaw-axis and the roll- axis and by directing output axes of the three axes away from corresponding mounting portions.

Title: Electromagnetic clutch
Inventor: KAKINUMA KATSUHIKO
IPC: F16D27/14
Filed: 1990-10-12
Granted: 1995-05-09
Abstract: A clutch is disclosed which includes an electromagnetic drive mechanism. A hub is frictionally secured on a drive shaft and has a flange portion radially extending from its outer peripheral surface. An annular armature plate is coupled to the flange and spaced from an axial end surface of the rotor. A plurality of threaded holes are formed in the flange portion of the hub to permit the use of a tool which detaches the hub from the drive shaft. An annular plate is disposed at an inner surface of the flange portion of the hub to cover the plurality of holes so that water from the outside of the electromagnetic clutch is prevented from entering through the holes. Thus, corrosion of internal parts is prevented and clutch life and performance are enhanced.

Patent CA-2063869-C (CA)
Title: Electrical actuator with means for preventing dither at a limit switch
Inventor: NELSON MARVIN D
IPC: H02P7/00
Filed: 1992-03-24
Granted: 1999-12-07
Abstract: The tendency of a motor-driven actuator driving against a dynamic (non-frictional) load to return upon reaching the limit switch sufficiently to again close the limit switch and create a persistent oscillation at the limit position can be prevented by planing a positive temperature coefficient thermistor across the limit switch involved. Such loads typically arise in actuators having spring-driven return capability, and can also arise when positioning air dampers and other loads where the actuator force is opposed by a spring or gravity.

Title: Marine steering apparatus
Inventor: KOBELT JACOB
IPC: B63H25/22
Filed: 1992-12-22
Granted: 1994-09-20
Abstract: A  fluid  power  apparatus  is  connected  to  a pressurized fluid supply and a conventional helm pump controlled by the helm of a vessel to shift the rudder. The apparatus comprises an actuator cylinder connectable to the rudder, and a servo cylinder and a main valve connected to the helm pump to pass fluid therebetween and between the actuator  cylinder.    The  actuator  cylinder  and  servo cylinder  have  respective  bodies  and  piston  rods,  and portions of the servo cylinder and actuator cylinder are connected together for concurrent simultaneous movement along  respective  longitudinal  axes.    Valve  shifting structure is responsive to a change in fluid signal from the helm pump applied to the servo apparatus.   Fluid diverting structure is responsive to a threshold supply pressure so as to actuate the valve to stop flow of supply fluid when  supply  pressure  drops  below  the  threshold pressure.  When pressurized fluid is available, the valve is actuated in response to a fluid signal from the helm pump and the actuator cylinder receives pressurized fluid from the valve and directs fluid back to the valve.  When pressurized fluid is not available, the valve is actuated in response to a fluid signal from the helm pump and the valve is effectively by-passed and the actuator cylinder receives  fluid from the helm pump and is actuated by manually applied pressures.

Title: Washing process
Inventor: PELTON ROBERT H
IPC: C11D7/22
Filed: 1991-09-27
Granted: 1999-01-12
Abstract: Brown stock washing of wood pulp is improved by adding  a water-soluble  cationic  polymer to the wash water.  The cationic polymer reacts with lignin solution present in the larger channels in the pulp mat to give a precipitate which lowers the flow rate of wash water through the  larger channels.   A more efficient wash water usage is obtained.
Patent CA-2092747-C (CA)
Inventor: CAREY JAY F II
IPC: C23F1/44
Filed: 1993-03-26
Granted: 2002-07-23
Abstract: Various metal coatings have been used for many years to inhibit oxidation of metals exposed to the natural elements of the atmosphere over a period of time. Terne alloy coatings which normally contain about 20% tin and about 80% lead are some of the most popular metal coating treatments to resist corrosion.      The special formulation of the present invention reformulates the terne coating to constitute a tin and lead based coating where tin constitutes at least 90% of the terne and lead amounts to less than 0.1% and preferably less than 0.05% of the terne. The low lead terne coating may also include antimony arid bismuth to provide strength and hardness to the low lead terne formulation having corrosion resistive qualities similar to that of standard terne coating formulations.      A weather-resistant strip roofing material is also disclosed and which has improved corrosion-resistant properties includes a strip of stainless steel which is pre-treated by an aggressive pickling process and/or a chemical activating process prior to applying a hot-dip tin coating. The pre-treatment of the stainless steel strip produces superior alloying between the stainless steel and the tin coating which reduces flaking of the tin coating.

Title: Slow sand filter for use with intermittently flowing water supply and method of use thereof
Inventor: MANZ DAVID H
IPC: B01D24/12
Filed: 1993-09-07
Granted: 2005-08-02
Abstract: An intermittently operating slow sand filter uses the damming of water in a raised pipe to provide a constant level of water in a slow sand filter container. The container includes a water inlet and outlet, and is partially filled with sand or other filter material. A pipe from the water outlet in the slow sand filter is raised upward to the desired level of water over the sand before descending to a water reservoir. Water backs up in the pipe and the container to the desired level above the top of the sand, even when the flow of water is intermittent. The schmutzdeuke forms at the top of the filter medium.      The water level in such a manually operated slow sand filter, using fine quartz sand as the filter medium, and at ambient temperatures (about 21°C) is maintained above about 1 cm above the top of the filter medium and below about 8 cm above the top of the slow sand filter. In another intermittently operating slow sand filter, the water level is controlled automatically when not being used at a desired maintenance level, and otherwise is kept in a desired range of levels above the top of the sand (or other filter material) in a partially filled container. Automatic control is provided by a control system that senses the water level in the slow sand filter. The supply of water may be from a pump or from a gravity flow controlled by a valve. The water from the automatic intermittently operating slow sand filter is supplied to a reservoir.      Water level in the reservoir may also be controlled within a desired range using upper and lower level limit detectors and a valve on an outlet line from the container to the reservoir.
