Filed: 1990-08-09
Abstract: Abstract of the Disclosure The tool includes a housing having two substantially semi-cylindrical members.  An air motor in the housing has motor end members located adjacent each end thereof.  Two O-rings, respectively disposed between the motor and the end members, are squeezable axially so as to be forced radially outwardly to abut the housing.  A manifold includes a chamber of a size that dampens Helmholtz frequencies in the exhaust air.  A bearing block includes an outer surface configured to transfer operating loads from a crank shaft extending through the bearing block to the housing.  Each of the members of the housing has an arm with a cylindrical opening for receiving a rotatable drive body.  The drive body has a knob including a shaft having an ear cooperating with an O-ring in the drive body for preventing the knob from inadvertently rotating between operating positions while the tool is in use.  An O-ring between the knob and the drive body isolates the housing from shock to the knob resulting when the tool is dropped.  A bushing disposed within the opening of one of the arms includes an outer surface having a plurality of serrations to provide a secure fit between the bushing and the arm.  A washer and a retaining ring are located adjacent the bushing.  A spring is located between the bushing and the retaining ring for biasing the drive body against the arm to provide friction between the drive body and the arm.  An elastomeric jacket surrounds the housing.

Title: Automatic Sorting Apparatus
Inventor: SUGIYAMA HIROAKI
IPC: B07C5/06
Filed: 1995-11-17
Abstract: The invention concerns an automatic sorting apparatus for sorting out pieces under process, such as fish and shellfish or industrial products, into different size groups. In the prior art automatic sorting apparatus, pieces under process are readily caught in sorting holes, making it difficult to obtain smooth sorting. The invention permits smooth sorting. An automatic sorting apparatus to this end comprises an endless conveyor having sorting holes and capable of excursion, an inner receiver disposed inside the endless conveyor for receiving pieces under process falling from the sorting holes, and an outer receiver disposed outside and below a U-turn portion of the endless conveyor for receiving pieces under process falling off the U-turn portion. Another automatic sorting apparatus comprises two or more endless conveyors having different excursion diameters and disposed one inside another at an interval. The sorting holes of each endless conveyer are smaller than those of the next outer endless conveyor. An inner receiver is disposed inside the innermost endless conveyor for receiving pieces under process falling through the sorting holes of that endless conveyor. An outer conveyor is disposed outside and below a U-turn portion of each endless conveyor for receiving pieces under process falling through the sorting holes of that endless conveyor.
Patent CA-2170270-A1 (CA)
Inventor: ISHIKAWA YOUHEI
IPC: H01P1/20
Filed: 1994-03-07
Abstract: A plurality of TEM mode transmission lines (L2-L5) are structured by pairs of thin film conductors (21 and 22, 22 and 23, 23 and 24, and 24 and 25) which sandwich thin film dielectrics (31 to 34) by alternately stacking the thin film conductor  (21 to 25)  and the thin film dielectric (31 to 34).  The phase velocities of TEM mode waves  which  are  propagated  at  least  by  two  of  the transmission lines (L2 to L5) are substantially equal to each other.   The thickness of each of  the thin film conductors (21 to 25) is smaller than the skin depth of the frequency used so that the electromagnetic fields of at least two TEM mode transmission lines among the TEM mode transmission lines (L2 to L5) are coupled to each other.          In this way, the skin depth can be increased effectively.          The conductor loss and the  surface resistance can be reduced  significantly  as  compared  to  those  of  the conventional  electrode.   By use of  this electrode,  a transmission line,  a resonator,  a  filter,  and a high frequency device are structured.

Title: Goalie hockey stick with improved stickhandling capabilities
Inventor: MAYHEW KENT WILLIAM
IPC: A63B60/32
Filed: 1996-03-28
Abstract: A goalie hockey stick including a shaft, a paddle and a blade. The paddle and blade are attached such that the angle between the paddle and blade is similar to the said angle on a conventional goalie hockey stick. The shaft's longitudinal axis is rotated and rigidly attached to the paddle so that the angle between the shaft and the blade is greater than the angle between the paddle and the blade, on the above said goalie hockey stick. The larger angle between the shaft and blade allows the goalie to handle the puck better. When the paddle is placed flat on the ice, the above said shaft's longitudinal axis rotation with respect to the paddle, will cause the shaft to be is close enough to the ice that a puck is prevented from sliding thereunder.  The above said shaft's longitudinal axis rotation with respect to the paddle will improve the durability of the above said goalie hockey stick, by spreading any stress across a larger surface area.
Patent CA-2174606-A1 (CA)
Title: Measuring system for partial discharges
Inventor: STEENNIS EVERT FREDERICK
IPC: G01R31/12
Filed: 1996-04-19
Abstract: The present invention relates to a method and a device for detecting partial discharges in cables and accessories, comprising the following steps of: interrupting the metal earth shield of the cable; connecting both sides of the interrupted sheath to a measuring instrument; arranging a connection between both sides of the interrupted sheath which is at least suitable for transferring the signals with the mains frequency; and displaying the signal, wherein only signal components with frequencies greater than 0.5 MHz are displayed.    As a result of these steps, the interference associated with the first mentioned frequency range is avoided. It is noted here that the signal/noise ratio of the frequency range applied according to the invention is more favourable.     In order to properly be able to examine  the quality of a partial discharge, it is important to relate it to the voltage of the cable in which the partial discharge takes place.  The present invention provides a method wherein prior to display the signal is combined with a signal representing the mains voltage.       It is especially attractive when the signal representing the mains voltage is generated in contact-free manner, for example in capacitive manner.
