Title: Earth fault circuit breaker
Inventor: LAM SHEIR C
IPC: H02H1/00
Filed: 1994-06-14
Abstract: ABSTRACT          An earth fault circuit breaker (10) for use in a circuit including an AC power supply and a load (11), which circuit breaker comprises a current-to-voltage converter (12) having two transformers for monitoring the current before and after flowing through the load J a leakage current/ voltage detector (13A) for processing the outputs (E1 & E2) of the transformers to produce a resultant voltage, a voltage comparator (16) for comparing the said resultant voltage with a predetermined reference voltage  to determine  if there  is a difference between the two transformer outputs, which is caused by an earth fault appearing at the load, and a switching driver (14) for disconnecting the load from the power supply in response to such a difference between the two transformer outputs exceeding the predetermined reference voltage, wherein each transformer has first and second primary windings (P1 & P2) arranged to be connected to opposite sides of the load and the two transformers are arranged to provide outputs at their respective secondary windings (S), corresponding to the normal load current (I2), in a substantially anti-phase relationship.     The circuit breaker  (10)  may optionally  include  another voltage  comparator  (21)  to  detect  overload  current  by monitoring the output of either one of the transformers.

IPC: B65H29/36
Filed: 1994-08-11
Abstract: For removing stacks of paper from a transport track via an exit (9), a carriage (21) is provided, with which the exit (9), which directly adjoins a packaging device (41), can be opened and closed in an essentially gap-free manner. For this purpose, the carriage (21) has a closure plate for closing the exit (9), which serves simultaneously as a supporting element (20) for the essentially rigid support of the stack of paper in the region of the extended carriage (21). As a result, the associated transporter (2) can have a relatively low number of transport belts (15). <IMAGE>
Patent CA-2130647-A1 (CA)
Title: Fluid dispenser
Inventor: MACKINNON TIM
IPC: B67D1/08
Filed: 1994-08-22
Abstract: ABSTRACT    A dispensing system for dispensing measured amounts of different fluids alone or in combination. The system has a manifold, a dispensing head, and a plurality of fluid lines extending between the manifold and the head. A pump is connected to the manifold. A fluid supply is connected to each line between the manifold and the dispensing head. The fluid supplies are spaced from the manifold. A valve is provided in each line near the manifold for opening or closing the line. Operating means selectively open one or more of the valves and operate the pump to provide a below-atmospheric pressure in the manifold. As the pump is being operated fluid is drawn from the supply means into the selected lines toward the manifold. After the desired amount of fluid has been drawn into each line each selected valve is closed. The pump is then operated to provide an above atmospheric pressure in the manifold and the selected valves are again opened to move the fluid through the dispensing head. One way valves prevent the drawn out fluid from returning to the fluid supplies.

Filed: 1995-03-20
Abstract: A video on demand computer system includes a plurality of storage media each storing a plurality of videos. The storage media are disks attached to a computer system. The computer system plays the videos on demand by reading out the videos from the disks as data steams to play selected ones of the videos for users responsive to received user performance requests. The computer system is programmed to monitor the numbers of videos being performed for each of the disks. Based on the monitoring function performed by the computer system, the computer system performs a load balancing function by transferring the performance of a video in progress from one of the disks to another disk having a copy of the video in progress. The computer system periodically performs a reassignment function to transfer videos between the disks to optimize load balancing based on the user performance requests for each of the videos. There are two phases to the load balancing performed by the computer system; a static phase and a dynamic phase. In the static phase, videos are assigned to memory and disks, and in the dynamic phase there is provided a scheme for playing videos with minimal and balanced loads on the disks. The static phase supports the dynamic phase which insures optimal real-time operation of the system. Dynamic phase load balancing is accomplished by a process of baton passing.

Title: Water purification system for dental instrument
Inventor: WOLF LEO H
IPC: A61C1/00
Filed: 1993-10-29
Abstract: A system for purifying water supplied to a dynamic dental instrument (10) has a  disposable element (20) having an iodinated resin (23). Disease causing microorganisms in water flowing through the element are neutralized with neutralizing agents released directly into the microorganisms when the microorganisms come into contact with the resin (23). Residual iodine is released as water passes through the resin (23) and remains between the element (20) and the dynamic instrument (10) to maintain dental unit water purity. A modified system for purifying water supplied to a dental unit and dynamic dental instrument (100) has two disposable elements (120, 122), each having an iodinated anionic exchange resin (23, 126) containing a continuous fix-rate released iodinated resin I(n). Iodine is released from the resin at a specified and consistent rate as water passes through the resin (23, 126) to maintain dental water purity.
Patent CA-2146230-A1 (CA)
Inventor: SHOURESHI RAHMAT A
IPC: D06F34/16
Filed: 1995-04-03
Abstract: A passive-adaptive vibration control system is provided wherein various elements of the system may be adapted on-line in response to sensed vibrations. A spring/weight vibration absorber (160, 165) is attached to a vibrating body, such as the drum (115) of a laundry machine (100), to absorb energy generated by the drum, to minimize the transmission of vibrations to a structure, such as the body of the machine (100) in mechanical communication with the drum. The mass of the weight (160) of the vibration absorber may be adjusted, on-line, to compensate for sensed vibrations. A vibration sensor (170) is connected to the vibrating body so as to sense the level of vibration above a desired level and to send a signal representative of that vibration to an electronic controller (180). The electronic controller (180) is designed to instruct an actuator arrangement (182, 184) to adapt the mass of the weight to compensate for the sensed vibration. For example, the weight (160) may be a chamber, the mass of which may be adjusted by adding or releasing a fluid to or from the chamber via the actuator arrangement (182,184) under the control of the controller (180). <IMAGE>

Title: Lumber defect scanning including multi-dimensional pattern recognition
Inventor: SOEST JON F
IPC: G01N21/898
Filed: 1995-04-12
Abstract: Grain defect scanning takes into account a broad set of data representing both wood grain structure and wood grain image to provide a multi-dimensional scan vector for an inspection point with wide variation therein relative to defect types. A library of similarly structured multi-dimensional training set vectors developed during a preliminary training session with known defect types is referenced by multivariate pattern recognition analysis to classify a collection of scan vectors associated with an article under inspection. By statistically matching scan vectors with training set vectors under pattern recognition analysis, physical locations on a wood article are identified according to known defect types.
