Title: Thermoplastic polymer composition
Inventor: KAWAHARA SHIGERU
IPC: C08L23/02
Filed: 1998-02-24
Abstract: The invention relates to a thermoplastic polymer composition comprising 100 parts by weight of a block copolymer and/or its hydrogenate having polymer blocks of an aromatic vinyl compound and polymer blocks of a conjugated diene compound, and from 5 to 95 parts by weight of a block copolymer having polymer blocks of an aromatic vinyl compound and/or an olefinic compound and polymer blocks having a constitutional unit derived from a (meth)acrylic compound; to a laminate comprising a layer of the composition and a layer of some other material; and to a hot-melt adhesive comprising the composition. As having good melt adhesiveness, the composition of the invention can firmly adhere in melt to various polar or non-polar materials. Using the composition, it is easy to produce laminates comprising a layer of the composition and a layer of some other material, through melt shaping or any other melt adhesion techniques. Since the composition of the invention is satisfactorily elastic and flexible, the laminates having a layer of the composition on their surface are flexible and elastic and have a good feel, and, in addition, they are highly safe because of their shock absorbability and cushionability.

Title: Multichannel radio frequency transmission system to deliver wideband digital data into independent sectorized service areas
Inventor: SHOENDUVE JAMES H
IPC: H04N7/16
Filed: 1996-11-12
Abstract: A one-way and two-way multichannel radio frequency transmission system and method employing sectorized broadcasting and reduces the effective bandwidth of the broadcast signal by multiplexing (16) available channels of signals (14) into a set of formatted independent digital bitstreams, each bitstream including all or a portion of available channels provided by the system program provider (10). The independant bitstreams are transmitted to transmitter towers using point-to-point transmission (19) methods. The transmitting towers phase modulate (20) and amplify the bitstreams to generate a set of independent modulated signals. Each transmitter tower includes a sectorized antenna for broadcasting (41) the modulated signals to a sectorized service area at a different frequency and opposite polarity then adjacent areas, so that each service area receives a different set of independent modulated signals. Each subscriber site (49) demodulates, demulpilexes and selects one channel from the received modulated signal.

Patent CA-2241868-A1 (CA)
Inventor: TJELTA SVEN O
IPC: B01F3/04
Filed: 1997-01-03
Abstract: A system of carbonizing water as part of making a carbonized beverage. There is a housing to contain the pressurized bottle of carbon dioxide, and also to define a chamber to receive a container of water. A pressure regulating valve maintains the carbon dioxide discharged from the carbon dioxide container at a predetermined lower pressure and directs the carbon dioxide to a selectively operable pressurizing valve that directs the carbon dioxide through a discharged nozzle into the water in the water container. The water container is closed by a mounting plug that interconnects with a receptacle block that is operably connected to the pressurizing valve, and also operably connected to a venting valve which is selectively operated to vent the remaining pressurized carbon dioxide after the carbonizing has been completed. In several embodiments, there is also provided a vent orifice to continuously vent carbon dioxide from the water container as the carbon dioxide is injected into the water, to obtain more complete carbonization.
Patent CA-2247583-A1 (CA)
Inventor: MOOIJEKIND JERRY G
IPC: E05B65/08
Filed: 1998-09-29
Abstract: 8.01  The present invention relates to the field of sliding doors and windows locking devices. Slidable doors and windows are increasingly popular in houses and all other types of buildings, and their own locking devices provides a very low protection, and are very easy to circumvent.   Intruders don't slide the patio doors or windows, no they lift them off their tracks and break in.   Our security locking device, when installed as recommended, in the middle of the door or window provides 50% of pressure on the upper half and 50% on the lower half, and makes it almost impossible for bunglers to lift the door or window.   Also incorporated in our locking device is a secured ventilation position which offer a complete protection for young children toward the family pool or other restricted areas, since in ventilation position the device is located at approximately 55 inches from the floor so cannot be reached by small children.   The main reason for this invention is to protect people. This device fits on almost all sizes of patio doors and sliding windows since it is telescopic. It is adjustable from 24 to 42 inches wide.

Title: Removable plug lock
Inventor: ETCHELLS GARRY MICHAEL
IPC: E05B27/06
Filed: 1997-03-20
Abstract: A lock with a plug (2) removable from a housing (16) is disclosed. The plug (2) includes a restraining member (46) and a protrusion (40) which engages a concentric groove (52) formed into a plug housing.  Intersecting the concentric groove is a longitudinal groove (50). Upon inserting an operation key the restraining member is forced into engagement with the concentric groove thereby preventing plug removal even upon alignment of the protrusion with the longitudinal groove (50). Upon inserting a removal key (42) the restraining member (46) is disengaged from the concentric groove so that the plug may be withdrawn upon rotationally aligning the protrusion (40) with the longitudinal groove (50). In this manner a simple and compact removable plug is provided to aid rapid lock re-keying.
