Title: Cyclic poly(aryl ether) oligomers, a process for preparation thereof, and polymerization of cyclic poly (aryl ether) oligomers
Inventor: MULLINS MICHAEL J
IPC: C08G73/22
Filed: 1990-08-09
Abstract: The present invention is directed to cyclic poly(aryl ether) oligomers and mixtures thereof, and methods for the preparation thereof in a highly dilute reaction medium under reaction conditions favorable for ring closure at low degrees of polymerization. These oligomers are represented by the general formula
       
 where each Y is divalent oxygen or divalent sulfur, each Ar is an aromatic diradical which comprises one or more C₆ to C₂₀ arylene groups and has at least one electron withdrawing group attached to an aromatic ring, and n is an integer from 1 to 20 with the proviso that for integer values of n equal to 1 or 2 all linkages between independent aromatic rings comprise at least one atom. 
     The present invention includes a process for the preparation of poly(aryl ethers) from cyclic poly(aryl ether) oligomers. These low melt viscosity cyclic oligomers undergo ring opening and chain extension upon heating in the presence of a catalyst, forming high molecular weight linear polymers with no coproduct formation. Finished thermoplastic parts and composites may be prepared using this technology with processing techniques normally restricted to thermosetting monomers.

Abstract: In the method for supporting the motorist in making a decision with respect to a change of lane of his motor vehicle, it is provided to measure relevant data with respect to the following traffic. From several successive measurements of the distance to a following motor vehicle, an evaluation index, which is visually or audibly indicated to the motorist, is formed, taking into consideration the differential acceleration of both motor vehicles necessary for maintaining a safe minimum distance. An advantage of the method is that the driver is provided with reliable information on the dynamic traffic behaviour in the more remote rear area. The device comprises a range finder in the rear area of the motor vehicle. An associated sensing head scans a predeterminable angle range. The logic of an evaluating device determines from the signatures of successive scans the differential acceleration and the distance between the two motor vehicles, from which the evaluation index is formed and indicated. <IMAGE>

Abstract: The invention relates to a cable duct, such as a railing duct, a cable routing duct, an apparatus installation duct or the like. Such a cable duct has a lower part, whose opening can be closed by a cover. In this case, the lower part on the one hand and the cover on the other hand have interacting couplings and mating couplings which permit both fixing and removal of the cover to and from the lower part respectively. On each of the opposite boundary walls of its opening, the lower part of the cable duct has an engagement space for one of the two ends of the cover. These engagement spaces are of mutually identical design. In this way, it is intended to be ensured that optionally both the one and the other end of the cover can be inserted into one of the two engagement spaces. The respectively other end of the cover has a latch in order to lock it detachably to the lower part. The attachment end of the cover is in contrast designed in such a manner that, once unlocking has been completed, the cover can be moved optionally into a removal position or into a position where it is open as far as possible and is secured in this position.

Abstract: A computer system bus is described which includes signal lines for controlling a high speed block data transfer mode between a bus master and a bus slave. When both master and slave devices support such a transfer, a high speed bus clock separate from the normal bus clock is used to transfer data. Devices not involved in the high speed block transfer see only an extended normal data transfer. The master and slave use bus control signals to determine the speed and data width of the high speed transfer. If the slave is unable to transfer the complete block of data at the high speed clock rate, it can signal the master to repeat the transfer of individual data items as necessary.

Abstract: This invention relates to the use of zinc as an anti-viral agent in scxual lubricants. A selected zinc compound which has antiviral properties, and which does not irritate the skin or mucous membranes, is provided in a sexual lubricant such as a water-soluble gel. The lubricant is spread on the surface of the penis, or inside the vagina, before sexual inter­course. The zinc can serve as a preventive agent to inhibit the transmission of genital her­pes through sexual contact, and may also help to reduce the spread of other sexually trans­mitted viral diseases such as AIDS. Such lubricants can be used in addition to a condom for maximal protection, or without a condom for a lesser yet still significant level of protection compared to unprotected intercourse. A preferred zinc salt which does not cause irritation during or after sexual intercourse comprises zinc gluconate, the salt of a carboxylic acid derivative of glucose. Other suitable zinc salts can be prepared from carboxylic acid deriva­tives or other oxidation products of other sugars.

Title: Process and apparatus for handling persistent objects in an object oriented programming system
Inventor: SHACKELFORD FLOYD WAYNE
IPC: G06F17/30
Filed: 1990-10-09
Abstract: A persistent data interface for an object oriented pro­gramming system provides a persistent class object. Any object which must survive a run time session is arranged to inherit from the persistent class object. Any object which inherits from the persistent class automatically becomes a persistent object. The persistent class in­cludes a "materialize" method for automatically retrieving a persistent object from nonvolatile memory (14) and placing it in volatile memory (13) if the persistent object cannot be located in volatile memory. A "demateri­alize" method is also included for removing an object from volatile memory and storing it in nonvolatile memory. Data integrity of the system is thereby preserved.

Abstract: 2.1 Automatic selective call diversion or call forwarding is to take place on an incoming call depending on information identifying the caller, with no need in each case for manual inputs for the call diversion concerned. 2.2 A call diversion controller is provided which is allocated to a called station and contains a call memory, in which the addresses or telephone numbers of possible callers are stored. Addresses or telephone numbers of stations which are to be activated on call diversion are assigned to this information, which in each case identifies a caller, and are read into the memory. A register is provided in which the information identifying the origin of a current incoming call is received and temporarily stored. This information is compared with the addresses of possible callers. When a match is found, the associated address or telephone number is made available to the other station which is to be called for a further call set-up.   2.3 The method enables a precisely designated diversion station to be activated during call diversion or call forwarding, specifically dependent on the respective incoming call. <IMAGE>
