Granted: 1998-02-10
Abstract: Vesiculated polymer beads are prepared in which a water-in-oil-in-water emulsion containing a cross-linkable polymer and a copolymerisable monomer in the oil phase is heated in the presence of an initiator to cure the polymer beads, wherein curing is commenced in a first stage in the presence of a substantially water-insoluble initiator and, when the beads are sufficiently stable, curing is completed in a second stage in the presence of an at least partially water-soluble initiator.  Preferably, the completion of curing is carried out at a temperature higher than that of the first stage.  The beads can be used in low odour paint formulations.

Abstract: A transmission line switching apparatus comprises an optical fiber connecting board for holding a plurality of first optical fibers, an optical fiber arranging board, arranged apart from the connecting board with a predetermined spacing between them in the horizontal direction, for holding a plurality of second optical fibers, and a robot for handling the second fibers. Each second optical fiber extends to the connecting board through the arranging board, and the distal end of the second optical fiber is detachably attached to the connecting board so as to be selectively connected to one of the first optical fibers. When the distal end of the second optical fiber is attached to the connecting board, the second optical fiber is laterally extended in a loosened state between the two boards. In this state, the entangled states of the second optical fibers near the two boards are sparser than that in the intermediate position between the two boards. Therefore, the robot can easily handle the second optical fiber.

Title: Signal generator
Inventor: PADULA SANTO ANTHONY
IPC: H03K17/97
Filed: 1993-10-28
Granted: 2004-09-07
Abstract: A signal generator (10} for generating an electrical signal which varies in accordance with movement of an actuating member includes a plunger (44) slidable mounted within a housing (12) which carries a pair of permanent magnets (58, 60) for generating a magnetic field to be applied to a hall effect generator (36). As the plunger (44) is moved relative to the hall effect generator (36), the magnets (58, 60) are also moved relative to the hail effect generator (36), thereby varying the magnetic field applied thereto. Accordingly, a variable output signal is generated as a function of the position of the input member.

Abstract: A container unloading device which includes a two-tiered rail system that has been adapted to include an upper set of feed rails that cycle carts carrying containers from the back of the system to the front of the system for unloading.  At the system's front end, the feed rails have sections of increased angularity which support the cart and container at an angle which increases accessibility to the container's contents.   The system also includes a set of transfer ramps which allow the cart to move from rolling engagement with the feed rails to rolling engagement with the lower set of return rails where the cart and unloaded container then move to the back of the system into a position for reloading.  The device may further  include  a  speed  reducer  which  retards  the  cart's acceleration down the sections of increased angularity.

Abstract: A rotary roller reamer (10) for a borehole has several rollers (11). Each roller (11) rotates about a fixed spindle (13) held at its ends in wedge blocks (14). The spindle (13) has two central passages (19), one at each end . At one end, passage (19) contains a freely slidable piston (21), which is subject to external pressure via a breather aperture (22). The other end passage (19) is blocked by a pressure plug (27) which, when removed, permits injection of grease through passages which include the bearing surfaces of t he roller (11) and spindle (13). External pressure is applied to the grease through piston (21), so that there is little or no pressure differential to otherwise force mud into the bearing.

In addition, the intermediate section further has a length of torque coil wrapped thereabout.  The torque coil preferably is wound in a coiled diameter which is the same as the first diameter of the proximal and distal sections of the stylet wire.  Through such  a  configuration  the  stylet has  an  overall  nearly uniformed diameter through its length.

Title: Swimming pool cleaner discs and assemblies
Inventor: RICE CHRIS A
IPC: E04H4/16
Filed: 1995-10-24
Granted: 1999-07-13
Abstract: Discs and a footpad for devices such as automatic swimming pool cleaners are disclosed. The discs incorporate upwardly-extending, non-truncated fins protruding radially from their peripheries. The peripheries themselves, moreover, define a plurality of tongues for increased flexibility, and both the discs and footpad may include ramped segments facilitating movement over obstacles extending from swimming pool surfaces.      Also disclosed are discs having series of slits spaced along portions of their peripheries. Each such disc may be part of an assembly including a "bib," or cap, that too may be slitted if desired. The slits of each component, when present, permit its effective surface area to increase as the associated cleaner climbs the side of a swimming pool, enhancing the maneuverability of the cleaner. By contrast, unslitted portions of the cap seal, or cover, the slits present in the disc to provide adequate suction for the disc against the pool surface.

Patent CA-2176405-C (CA)
Inventor: GARLAND STUART MANDEL
IPC: H04M11/00
Filed: 1996-05-13
Granted: 2000-01-04
Abstract: The test system of the invention uses suppressed ringing connections from a test unit to the customer premise equipment via the central office to establish connections for performing the loop-back test. The suppressed ringing connections are established over standard voice trunks between a switch in the central office and the test unit by a central office service unit (COSU) such that the number of lines that can be tested simultaneously is limited only by the number of trunks linking the COSU to a switch. Because these trunks are relatively inexpensive and simple to install and maintain, the test system of the invention can be readily installed and expanded in the existing network to provide virtually any level of monitoring capability.

Title: Packet transferring device
Inventor: MURATA MAKOTO
IPC: H04L69/40
Filed: 1996-12-17
Granted: 2001-09-11
Abstract: When a data transferring operation ends in failure because a call was released in the midst of data transfer or the like, the data should be transferred again.  In this data re-transfer, it is desirable to reduce the time spent for data transfer regardless of the functions provided by a terminal side.  For this purpose, an order number is assigned to a packet containing data before it is sent.  This number is stored in a storage section.  Further, when a packet is confirmed as to its receipt by a transmission receiver, the order number of the packet is also stored.  For a resending operation of the same data, a transmitted packet and an untransmitted packet can be discriminated from each other through comparison between order numbers of a sent packet and a transmitted packet.  Based on the discrimination result, only untransmitted packets are subjected to a resending operation.
