Abstract: THERMOOXIDATIVE STABILIZATION OF POLYOLEFINS WITH A  TRI-SUBSTITUTED-TRIAZINE UV LIGHT STABILIZER         AND A PHOSPHOROUS ACID ESTER               ABSTRACT OF THE DISCLOSURE      Only two symmetrical stabilizers in a polyolefin or copolymer thereof provide thermooxidative or antioxidative stability. One is a phosphite, namely a triaryl phosphite or a pentaerythritol phosphite, symmetrical about the P and C atoms respectively, present in a trace amount, less than 0.1 phr; the other is a tri-substituted triazine derivative ("PIP-T") in which the 2-, 4- and 6-positions of the triazine ring are substituted with a polysubstitut-ed piperazin2-one, piperazine, or piperidine. No other stabilizer such as a hindered phenol antioxidant, is re-quired. Articles thermoformed from the stabilized poly-(alpha-olefin) or copolymer thereof may be used under the hood or the dash of a vehicle, and, in containers for packaging goods, all of which articles are subject to thermooxidative degradation even if they are not subject to ultraviolet light degradation.

Inventor: SPIEGEL SI
IPC: A47G33/06
Filed: 1990-07-16
Abstract: An improved apparatus for mounting artificial tree branches to an artificial tree trunk.  A series of bracket guideways, each bridged by a horizontal pin, are adapted for pivotal engagement each with a branch member for movement between stowed and operative positions.  Each branch mounts a hinge piece adjacent to one end adapted for pivotal engagement with the horizontal pin as the branch moves between stowed and operative positions, the hinge piece suspending the branch radially from the tree trunk when in an operative position.  Snaps secure the branch in a groove on the hinge piece to restrict movement of the branch about the bracket when in either a stowed or an operative position.  Extended bracket guideways and a hinge piece back stop also assist in securing the branch to the hinge piece and restricting radial movement of the branch about the bracket.

The adhesive films containing the precompacted core mixture are adhesively bonded to the continuously fed cover strips.  The apparatus comprises a stretching roller for each of the adhesive films, a device for the uniform application of the core mixture, first means for forming a settable running-in angle and the V gap, second means for supporting the lower adhesive film and third means for the concluding pressing and heating, as well as a device for cutting to length.

Title: In-circuit contact monitor with impedance bridge
Inventor: FRIESEN WALTER
IPC: H03K17/18
Filed: 1990-11-28
Abstract: An in-circuit contact monitor for providing reliable and safe detection of the position of fail safe, or vital, circuit contacts in railroad signaling and inter-locking control circuits comprises an impedance network arranged in a bridge configuration, a low-power, high-frequency signal source, an isolation transformer, and a pair of DC blocking capacitors.  The low-power, high-frequency AC source provides energy for an isolated circuit which is used in detecting the toggling of an individual circuit contact.  The circuit is configured such that the vital circuitry, which is connected to the circuit contact, is completely isolated from the DC components generated by the low-power, high-voltage AC source.  The isolation transformer acts to isolate the monitor system from the in-circuit contact monitor circuitry and thus the vital circuitry.

IPC: G06F12/10
Filed: 1990-12-19
Abstract: A predetermined number of logical page addresses are effectively translated into corresponding real ones. The number of the logical page addresses is determined by (M+N) bits and, each of the logical page addresses includes upper M-bit and lower N-bit.  Logical page address registers, whose number is equal to 2N, are provided to respectively store the predetermined number of logical page addresses applied.  Address translation buffers (whose number is also equal to 2N) each stores 2M real page addresses which are grouped according to each of the lower N bits.  The address translation buffers receive the upper M-bit of one of the logical page addresses, and output real addresses.   An address translation controller receives the outputs of the address translation buffers and also receives the lower N-bit, and selects the real page addresses using the lower N-bit.  The selected real page addresses are applied to a plurality of real address registers.  A page number comparator determines whether or not the upper M-bit of one of the logical page address coincides with the upper M-bit of each of the remaining logical page addresses.  The page number comparator outputs the comparison results which allow the real address(es) stored in the real address registers to be applied to a main memory.

Abstract: A  proximity  detection  system  which  combines  the advantages of an electrostatic  (electric)  field coupling mechanism with those of an electromagnetic coupling mechanism in order to overcome the disadvantages of the respective individual coupling mechanisms.  The system includes a coded tag which is excited with an induction field, i.e., by using an electromagnetic coupling mechanism as has been done in the past in such proximity identification systems,  but which transmits stored data back to the receiver using both an electric field coupling mechanism and an electromagnetic field coupling mechanism.  The receiver, in turn, is provided with a novel preamplifier circuit arrangement,  so that it can simultaneously receive signals via either or both of these coupling mechanisms.

Title: Emergency lever handle for narrow stile deadbolt locks
Inventor: COWLEY J
IPC: E05C3/12
Filed: 1991-07-15
Abstract: Abstract The majority of locks used on commercial buildings are of the Bradstock type manufactured by Adams Rite Incorporated. These locks are generally locked from the outside with a key and from the inside with a thumbturn. Because the thumbturn may be difficult to operate in panic conditions where there may be pressure against the door by people trying to get out, a thumbturn is a very undesirable lock and many jurisdtictions in North America have legislated against them and have suggested ninety degree door handles in their place. This invention therefore relates to the provision of a kit of parts that will permit the conversion of such locks from the thumbturn to a ninety degree turn handle for the locking or unlocking of the door from the inside. These conversions do not require the removal of the lock from the door for installing the kit or any modifications of the lock.
