Title: Sonar array mounting for sonobuoy
Inventor: BUCKINGHAM DAVID EDWIN JAMES
IPC: G10K11/00
Filed: 1991-03-15
Granted: 2001-05-08
Abstract: A sonobuoy comprises a sonar array mounted on arms (2) that are pivotally connected to a central support (3) and housed by an outer housing (1). Upon entry of the sonobuoy into water a float (8) is deployed which since it is connected to the central support (3) by a line arrests the downward motion of the central support (3). The outer housing (1), by virtue of its inertia, travels on uncovering the arms (2) and positively locating the arms (2) by pulling on lines (17) connected to the arms (2). Th e use of the motion of the housing (1) to deploy the arms (2) eliminates the requirement for spring powered motors reducing the cost of the sonobuoy.</SD OAB>

Title: In-service activator for a broadband exchanger
Inventor: YOSHIMURA SHUJI
IPC: H04Q3/545
Filed: 1992-03-18
Granted: 1997-01-14
Abstract: An in-service activator for a broadband exchanger has a duplex system structure, in which a first system and a second system form a duplex pair.   The first system and the second system in the duplex pair each has at least one [1] channel converter and a switcher.          A channel converter stores channel setting information for use in routing a cell inputted from a line, and outputs the cell inputted from the line by attaching the channel setting information to the cell.    The switcher switches a cell outputted from a channel converter.     The interfacer stores, in a channel converter of a to-be-activated standby system in the duplex pair, the channel setting information read from the corresponding channel converter of an act system in the duplex pair.

An Electromagnetic drive is used to drive the shutter between ON and OFF positions.      The fibre is centrally located relative to the fibre mount. A plurality of shutters, each with its own drive may be arranged in line, in a single strip module.
Patent CA-2100653-C (CA)
Inventor: SCHWEITZER EDMUND O JR
IPC: G01R15/24
Filed: 1993-07-15
Granted: 2000-04-11
Abstract: A voltage monitoring device for a three-phase ungrounded delta-connected power system utilizes liquid crystal optical shutter devices capacitively coupled between phases of the system such that the combined light transparency of the optical shutter devices varies with system phase-to-phase voltage. A light source projects a light beam through the optical shutter devices to a light detector such that the output of the light detector is dependent on the system voltage. A control circuit responsive to the output of the light detector provides a control signal when the system voltage falls outside of a predetermined operating range.

Filed: 1994-01-10
Granted: 1999-02-16
Abstract: An  apparatus  for  cutting  baled  crop  materials particularly  of  the  cylindrical  bale  type  comprises  an apparatus in the form of a conventional chain saw in which the chain is modified so that either the slide links or the guide links  include  an  outwardly  projecting  cutting  plate.

Title: Device for orientating the bases and caps of hard gelatin capsules
Inventor: RIBANI ANGIOLINO
IPC: A61J3/07
Filed: 1994-02-03
Granted: 2004-04-27
Abstract: The bases and caps are aligned in two stages, with displacement by first pointed pushers (13-31) into corresponding calibrated horizontal channels (12-29) followed by displacement by second pushers (21-44) into corresponding calibrated vertical and descending channels (312-329). The second., pusher (21) pushes the bases horizontally into the wider terminal part (20) of the said descending channel, where the base is sucked by its sealed end and inserted into the corresponding supporting socket (1), with a vertical disposition and with the opening upwards, The second pusher (44), operating with the caps, acts on the intermediate parts of these with a point (144) which causes the caps to rotate with the opening downwards and transfers them with a vertical disposition into the wider terminal part (42) of the descending channel where the cap is held by a suction tube (46) which inserts it into the corresponding supporting socket (2). The seats (28) to which the caps are fed for orientation are provided at their bases with supports (37-137 or 39-139) which ensure that the caps are stopped at different levels and that they have the best disposition with respect to the first orientating pushes.

Title: Absorbent articles
Inventor: COLE ROBERT
IPC: A61F13/472
Filed: 1994-02-21
Granted: 2006-04-04
Abstract: The present invention provides improvements in absorbent products, but is particularly useful with urinary incontinence pads. An embossed pattern on the bottom layer of the double layer absorbent core construction improves the removal of urine or other fluids from the discharge zone to be ready for next void. One or more V-shaped notches cut at both ends of the pad provides the ergonomic fit of the pad to reduce the inevitable stiffness. The sides are designed as a flap which curves during the sealing process and provide natural curved flaps which form a soft gasket cushion and yields extra leak protection in the crotch area.

Title: Method and apparatus for inserting a communication wire through a pipeline by air flow
Inventor: TAGUCHI KINJI
IPC: G02B6/44
Filed: 1994-04-08
Granted: 1997-11-25
Abstract: A method and an apparatus are provided for inserting and removing a communication wire, in and out of a pipeline by air flow, in which static electricity can be prevented from being generated, and a long communication wire can be inserted and removed.  The communication wire is fed from a reel, and inserted into a pipeline through a blowing head.   Compressed air is also sent from a compressor to the pipeline through the blowing head.  A drop cylinder is attached to a T-branch on the way of the pipeline, conductive material stored therein is supplied into the pipeline at a controlled rate.  A recovery bottle is attached to the outlet side of the pipeline so that the air flow blowing out of the outlet side is passed through a filter 11, and at the same time the conductive material is recovered.  By making the conductive material pass through the pipeline  together  with  the  air  flow,  generated  static electricity can be eliminated, and the communication wire can be prevented from contacting tightly with the pipeline because of the static electricity.

Abstract: Ball cap storage rack comprising a wire or rod stock frame including a plurality of rods configured to form an elongated, generally rectangular-shaped back with side capture bars and a pair of hooks at one end.   The back has a width slightly narrower than the width of a typical baseball cap visor and is adapted to have its length running vertically when in normal use.  Two additional sets of rods are arrayed along opposite sides of the back to form side capture rails, and define visor edge receiving openings.   The upper ends of the rails are deformed to provide a closet pole hanger at the upper end of the rack,  and the lower ends are deformed to form the capture fingers at a lower portion of the device.  To store a plurality of baseball caps in the rack, the caps are placed with their visors flat against the back with the soft cap portion collapsed forwardly and the bill of each successive cap slipped behind the preceding one and the folded cap nested against the same part of the preceding cap.  The visor edges protrude through openings in the rack sides.  The caps are restrained in the rack by capture fingers at the lower ends of the side rails.
