Patent CA-2038499-A1 (CA)
IPC: B60R22/18
Filed: 1991-03-18
Abstract: A seat belt anchor for detachably mounting a seat belt on a bolt has a shank extending axially from a vehicle body panel and a bolt head projecting in a radial direction from the shank.  The seat belt anchor has an anchor plate connected to a seat belt.  The anchor plate has a keyhole shaped slot including an access portion for receiving the bolt head when the access portion is registered with the bolt head and a retaining portion which is narrower than the bolt head and further from the seat belt than the access portion for receiving the shank of the belt.  The anchor plate is mounted on the bolt when the retaining portion of the keyhole shaped slot is registered with the bolt head.  An axially yieldable spring carried by the anchor plate axially engages the bolt head to urge the anchor plate into engagement with the bolt head.  A spring and a pair of detent bosses carried by the anchor plate engage with the bolt head to retain the anchor plate radially holding the bolt in the retaining portion of the key hole slot.  The anchor plate is detachable from the bolt by depressing the anchor plate axially towards the vehicle body panel as permitted by yielding of the axially yieldable spring to disengage the detent bosses from the bolt head and allow sliding movement of the anchor plate in the radial direction to register the bolt head with the access portion.  This allows the detaching of the bolt head through the access portion.

Abstract: UNSUPPORTED SINTERED CBN/DIAMOND CONJOINT           COMPACTS AND THEIR FABRICATION                 ABSTRACT OF THE DISCLOSURE The present invention is directed to sintered polycrystalline CBN/diamond conjoint compacts which are unsupported, fabricated in the substantial absence of catalyst/sintering aid material, and exhibit CBN crystal-to-crystal bonding.  The absence of catalyst/sintering aid material should make these conjoint masses fully dense and thermally-stable. The unsupported, sintered CBN/diamond conjoint compacts disclosed herein can be fabricated by subjecting a mixture of CBN or a CBN-forming material, and diamond particles in the substantial absence of catalyst/sintering aid material, and diamond forming an unsupported sintered polycrystalline CBN compact characterized by CBN intercrystal bonding and containing diamond particles throughout the conjoint compact.  Feed for forming the novel conjoint compact includes PBN, monocrystallline and polycrystalline CBN, and boron-rich polycrystalline CBN.

Title: Remote control impact protection bumper
Inventor: HODGE MICHAEL A
IPC: H05K7/00
Filed: 1991-11-04
Abstract: Abstract - Remote Control Impact Protection Bumper I would imagine that you have a hand held remote control device for your television, or your VCR, or your stereo system, or your garage door. I ask you, "How many times have you dropped the remote control device on the floor; or accidently knocked the remote control device off the coffee table?"      As you are probably well aware, the hand held remote control devices manufactured today, for televisions, VCR's, stereo systems, garage door openers, etc., are not made durable enough to withstand rough treatment.      Based upon the growing demand for televisions, VCR's, stereo equipment, garage door openers, etc., equipped with hand held remote control devices, and the fragile nature of the contruction of the hand held remote control devices, I saw a need for a product that will help protect the hand held remote control devices from accidental breakage; and help ex-tend the user life of the hand held remote control device.      The present invention provides a rubberized impact absorbant bumper that is installed around the outer edges of the hand held remote control device.      The present invention is a rubberized rectangular shaped impact absorbant bumper designed in such a way the user simply stretches the present invention around the outer edges of the hand held remote control device.      The present invention, once installed on a hand held remote control device, will help protect the hand held re-mote control device from accidental breakage, or damage, if the hand held remote control device is dropped, or handled in a rough manner.

Title: Low pressure inlet ring subassembly with integral staybars
Inventor: GROENENDAAL JOHN C JR
IPC: F01D25/24
Filed: 1991-10-17
Abstract: 56,203 ABSTRACT OF THE DISCLOSURE         Integral cast inlet ring sections for low pressure steam turbines are disclosed.  Preferably, semicircular inlet ring sections from opposing sides of the steam inlet are joined together by integral staybars to form an inlet ring subassembly.  After fabrication into a turbine inner cylinder, the two inlet ring subassemblies are preferably joined by a horizontal joint, such as a bolted connection, to form a circular inlet ring.  The present invention eliminates welds and other connections typically associated with staybars and thereby eliminates a source of stress concentration and fatigue failures in steam turbines.  The present invention also permits the inlet ring to be welded to a flange in a manner which eliminates potential delamination of the flange by fusing the sites of potential delamination.
Patent CA-2055205-A1 (CA)
Inventor: SPARKS THOMAS C
IPC: H04M11/06
Filed: 1991-11-08
Abstract: Network terminating terminal apparatus,  for use in an Integrated Services Digital Network, comprises a U-interface and a S/T interface.  The U-interface allows the integrated terminal apparatus to communicate with a central office directly, without a separate network terminator.  Remote terminals may be connected to  the  network  terminating  terminal  apparatus,  via  its  S/T interface.  The network terminating terminal apparatus serves then as a conventional network terminator.  The network terminating terminal apparatus includes circuitry for controlling D-channel access by the integrated terminal apparatus.  The circuitry detects the framing of the signal received at the U interface and the D-channel information from the remote terminals and ensures that the D-channel data from the integrated terminal apparatus is supplied to the S/T interface at the appropriate time for insertion into the D-echo channel of the signal returned to the remote terminals. In addition, the D-channel data from the integrated terminal apparatus is supplied to the U interface, with the D-channel from remote terminals,  for transmission in D-channel of the signal to the central office.

Title: Television receiver
Inventor: SHELLARD CHRISTOPHER J
IPC: H04N7/08
Filed: 1991-12-20
Abstract: An arrangement for enhancing an image corresponding to a television signal including a digital component includes a variable bandwidth filter and a control unit for controlling the bandwidth of the filter in response to the bit error rate (BER) of the digital component of the television signal. The control unit increases the bandwidth as the BER and therefore the signal quality increases and decreases the bandwidth as the BER and therefore the signal quality decreases. In one embodiment, the control unit is responsive to both the BER and the "darkness" of the image represented by the television signal so as to restrict the bandwidth more for relatively dark areas than for relatively light areas.
