Title: Rotary mechanism of a space vehicle having an integrated stacking system
Inventor: SCHOEFFTER JEAN-PIERRE
IPC: F16C25/08
Filed: 1991-10-09
Abstract: DESCRIPTIVE ABSTRACT            On space vehicles, the rotary mechanisms, such as those comprising one or more ball bearings (14; 14') are equipped with stacking systems (32, 32'), which join the parts (10, 12) which have to rotate with respect to one another during the launch phase.  These stacking systems (32, 32') are then released by heating shape memory material members (46, 46').  The use of these members makes it possible to place stac-king systems as close as possible to the bearings, so that the forces produced by the launch pass directly from one part to the other without loading the balls of the bearings.  Therefore the dimensions and weight of the latter can be minimized.            (Fig. 1)
Patent CA-2054361-A1 (CA)
Title: Cellular telephone service using spread spectrum transmission
IPC: H04W88/08
Filed: 1991-10-28
Abstract: A spread spectrum processing system (10) that employs wide bandwidth spread spectrum radio transmissions overlaid over the existing cellular voice signals to simul-taneously provide additional cellular services without causing objectionable interference to current users of the cellular voice channels. The spread spectrum radio transmis-sions also support a large number of low rate digital messages. Both vehicle location and massaging functions are obtained without sacrificing any of the existing voice channel capacity. The cell site processor (40) is designed to share the existing cellular frequencies, real estate, antenna towers, antennas (31), and low noise amplifiers (32) used in the cell site radio frequency receiver chain. The only additional cell site equip-ment is the spread spectrum signal processor (3240 The processing system provides a means for achieving vehicle location accuracies that are improved by greater than two orders of magnitude over that which is possible by the current transmissions in that band. It provides a means of achieving transmit power control of the vehicle transmit-ter (11, 12) to combat the extremely large variation (dynamic range) of radio signal path loss to the receiving sites. It also provides a means of excising at the receiver the ex-cessively strong conventional voice cellular signals that are not under power control which ordinarily might interfere with the successful reception of the new broadband signals.
Patent CA-2055525-A1 (CA)
Title: Tufting apparatus
Inventor: INGRAM GARY L
IPC: D05C15/24
Filed: 1991-11-14
Abstract: TUFTING APPARATUS     ABSTRACT OF THE DISCLOSURE    Apparatus for producing tufted textile goods employs a plurality of hollow needles which serve as backing openers, the backing openers being carried on a widthwise extending member which is reciprocated in a vertical direction to cause the backing openers to penetrate a backing.   Yarn is transported pneumatically through the backing openers and implanted into the backings as yarn tufts, the backing being shifted in the transverse direction by an amount corresponding to the spacing between adjacent backing openers in order to implant a transverse row of tufts.  Each yarn is trained about a feed roller which is selectively moved into peripheral engagement with a drive roller when the yarn is to be fed to the needle.  The yarn transverses a path from the feed roller to the needle which includes a yarn clamp and a yarn pullback mechanism.  When yarn is being fed the clamp is released and the pullback mechanism provides a first path for the yarn to travel to the needle, but when that yarn is no longer to be fed to that needle, the clamp is actuated to clamp the yarn and the pullback mechanism thereafter draws the yarn back from the needle into a second and longer path, and the feed roller is disengaged from the drive roller.  A knife blade is associated with each backing opener and positioned on the opposite side of the backing so as to engage the flat angled surface of the backing opener which forms its pointed tip.

Title: Personal mobile communication system with call bridging
Inventor: MISKA RICHARD A
IPC: H04W76/02
Filed: 1992-02-12
Abstract: PERSONAL MOBILE COMMUNICATION SYSTEM WITH CALL BRIDGING    Abstract A communications system permits a personal mobile telecommunications device user, such as a cellular telephone subscriber, to complete a connection to a calling party that has attempted to reach the subscriber using the subscriber's assigned telephone number, even when the subscriber is roaming outside of his or her home area. The system includes a messaging and bridging complex having an associated database, which receives a call placed to the subscriber. If the subscriber is out of his or her home area so that the call cannot be completed, information stored in the database is used to initiate transmission of a paging signal to the subscriber. The connection to the calling party is held in the complex for a predetermined period after the paging signal is transmitted. The mobile telephone user, upon receiving the paging signal, may initiate a call from their personal mobile telecommunications device to the messaging and bridging complex, which bridges the subscriber and the calling party together. The system can also include interactive voice response equipment for advising the calling party that the call cannot be completed and that a paging signal is being transmitted. The calling party may also be offered other options, including an opportunity to use a voice mailbox or other facility to leave a message in the event that the call cannot be completed.
