Filed: 1993-09-29
Abstract: A one-piece attachment device for mounting an end of a fluid actuated member on a support component. The attachment device has a plurality of first flexible fingers which terminate at a tip provided with an outwardly extending shoulder and a tapered caroming surface. The fingers are moved inwardly by engagement of the caroming surfaces with the support component as the fingers pass through an aperture formed therein, and thereafter attempt to return toward their original.position. The finger shoulders engage the support component to secure the attachment device to the support component. A second plurality of inwardly and upwardly extending flexible fingers are also provided on the attachment device and define an interior opening. A mounting stud of a fluid actuated member is inserted through the interior opening and the second fingers will move outwardly initially upon passage of the stud therethrough, afterwhich the finger attempt to return toward their original position securely gripping and retaining the stud therebetween to secure the fluid actuated member to the attachment device. In another embodiment the second fingers have inwardly extending tangs, the tips of which form the interior opening for securing and gripping the mounting stud therein.

Title: Method and apparatus for discontinuity detection in magnetisable material
Inventor: DRURY JOHN C
IPC: G01N27/82
Filed: 1993-02-05
Abstract: Method and apparatus are disclosed for detecting discontinuities (such as pits or cracks) at or below the surface of magnetisable material. An array of sensors is provided at or near the surface of a material arranged to detect magnetic flux leakage occurring when a magnetic field is induced in the material. The sensors in the array are coupled in respective pairs (differential pairs) such that when one member of a respective pair overlies a discontinuity, a differential output signal is produced dependent on the difference between the output signals from the sensors comprising the respective differential pair. Warning means is actuated in response to the differential output signal on indication that a discontinuity has been located. Typically the warning means is actuated only in response to differential output signals greater than a predetermined threshold value.

Title: Roller skate brake assembly
Inventor: HARKNESS SCOTT
IPC: A63C17/14
Filed: 1994-04-29
Abstract: A brake assembly is provided for attaching to the frame of a roller skate. The brake assembly includes a brake head that supports a brake pad and a sensor. The sensor is adapted to identify when the skate has been tipped to one side a predetermined amount. The brake head is movably connected to the frame of the skate by an attachment tab or guide housing. When the skate is tipped to one side, the sensor contacts the ground and moves the brake head with the brake pad towards the wheels. Once the skate has been tipped the predetermined amount, the brake pad is brought into frictional engagement with the wheels. In one embodiment,  the brake head moves  transversely relative to a longitudinal axis of the skate. In another embodiment, the brake head moves normally relative to the longitudinal axis.  In a further embodiment, the sensor does  not  require  physical  contact  with  the  skating surface, but instead uses a mercury switch to sense when the skate has been tipped to one side.

Patent CA-2141733-A1 (CA)
Inventor: HAYASHI MASAKI
IPC: H04J13/00
Filed: 1995-02-02
Abstract: In a base station which has a plurality of antennas, each of a plurality of comparison circuits operates to compare correlation levels, which are obtained by despreading received signals for a plurality of channels, with each other with respect to the antennas. Each of a plurality of transmission antenna selecting circuits operates to determine from which antenna a transmission signal is to be transmitted for every channel. Each of a plurality of multiplexing circuits operates to multiplex the transmission signals of the individual channels, which are spread, for every antenna. As a result, on the basis of the result of the comparison of the correlation levels with respect to the antennas, a transmission antenna is selected for every channel, and the signals of the channels that are to be transmitted by a given antenna are multiplexed, whereby the base station achieves transmission diversity.
