Abstract: RADIATOR CORE HAVING SOLDERED CONNECTIONS          ABSTRACT OF THE DISCLOSURE:    A  radiator  core is provided that has  upper  and lower  header  plates,  a plurality of tubes  extending between  the  header plates,  and a plurality  of  fins fitted  to and extending from the tubes.   Each of  the upper  and  lower  header plates  has  a  plurality  of apertures formed in it,  one for each of the tubes, and each aperture is surrounded by a collar.  The plurality of tubes extends through the respective collars in each of   the  upper  and  lower  header  plates,   and  the connection   between  each  of  the  collars  and   the respective tubes is soldered.   The soldered connection is made by first force fitting the header plates  which are  preformed  having  the collars in  them  over  the tubes,  then  dipping the assembly of the header  plate and tubes first into a flux bath and then into a solder bath.   The use of the collars significantly  increases the  contact  area  between the tubes  and  the  header plates, thereby rendering a stronger joint.

Title: Light stabilizer comprised of aryl nitrogen compound and uses thereof
Inventor: OOTAGURO KUNIHIKO
IPC: G11B7/244
Filed: 1990-05-07
Abstract: Certain types of aryl nitrogen compound are found to be useful not only for effectively rendering dyes lightfast but also for using as an additive that has high solubility in solvents and sufficiently good miscibility with dyes to insure that their solubility will not be impaired.  They can be used for preventing various reactions that cause deterioration by light in organic dyes, in particular cyanine dyes.  They can also be used for improving the keeping quality and recording and reproduction characteristics of optical recording media that use organic dyes in the form of thin films.  Representative examples include N, N-lower alkyl substituted nitroso-anilines, phenol or naphthol derivatives having at least one nitroso group, nitrosodiphenylamine and its derivatives and 1-pycryl-2, 2-diarylhydrazyl free radicals.

Patent CA-2021795-A1 (CA)
IPC: H04W48/16
Filed: 1990-07-23
Abstract: A channel selection system for radio communication equipment which uses a control channel for interchanging control signals for connection and a plurality of data channels for interchanging data and emits an electromagnetic wave by using any one of the data channels after determining that it is idle by carrier sensing. The system rarely selects a data channel adjoining the control channel since the probability that such a data channel is registered as an idle channel is extremely low. The system, therefore, reduces the possibility of the equipment being unable to use the control channel due to the influence of power leaking from the data channel adjoining the control channel.

Patent CA-2026104-A1 (CA)
Title: Telecommunications system
Inventor: BARNES NIGEL E
IPC: H04W72/08
Filed: 1990-01-26
Abstract: A communication procedure suitable for a cordless telephone system involves time division duplex radio communication between a handset (11) and a base station (3) using alternating bursts of transmission over a single radio channel. Once a radio link has been set up, initial transmissions carry a synchronisation logical channel (S) and a signalling logical channel (D) multiplexed together, but the link may switch to bursts carrying a communications logical channel (B) for the speech data and the signalling logical channel (D). Burst synchronisation is achieved by the asynchronous detection of words in a synchronisation channel (S). These words have bit patterns reducing the probability of incorrect asynchronous detection of them. If one part ceases to receive handset signals from the other, it transmits a special signal, informing the other part. This enables both parts to detect the failure of a link at substantially the same time, so that their actions to re-establish the link are synchronised.

Title: Method and apparatus for making roofing shingles

IPC: B05C19/06
Filed: 1991-04-25
Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for making asphalt shingles and particularly for applying varying overlay patterns of granular material to a web of roofing material to produce shingles of randomly varied appearance when the web is cut into shingles.  Pattern variation is achieved by several techniques, including the use of irregular overlay imprint shapes and spacings, the staggered omission of one or more overlay imprints from the web shingle lanes, and the random omission of one or more granule drops during coverage of each pattern to change a randomly selected imprint from a predetermined granule color to the backfall mixture shade. The apparatus includes provisions for automatically changing the granule flow rate to accommodate speed changes.  Pro-vision is further made for resiliently supporting the web to prevent web damage during the cyclical granule drop.

Abstract: Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed.  In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes.  Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism.  Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used.  Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved.  Furthermore, since the private branch system interface uses a frame which consists of a control window area for controlling its transmission and a cell multiplexing area for multiplexingly transmitting cells, bidirectional transmission between the broad band switching node and a plurality of terminal equipments can be achieved with a single extension transmission line.  In addition, since a frame construction which satisfies the ATM method is used, different information transmission speeds can be flexibly selected.  Thus, high through-put characteristic and statistic multiplexing effect intrinsic to the ATM method can be accomplished even in the extension line interface.
