Abstract: Epoxy resins containing both terminal hydroxyl groups and epoxy-derived groups are prepared by advancing a polyepoxide with a polyol and terminating the reaction at a point such that the epoxy resin reaction product contains both epoxy and terminal hydroxyl groups. The epoxy groups are then further reacted to form epoxy-derived groups and the rate of curing is further improved. The resulting epoxy resins exhibit lower melt and solution viscosities than those exhibited by conventional epoxy resins having the same epoxy equivalent weight, as well as curing quickly when used. The resins are usefully employed at high solids levels in can coating formulations and other epoxy formulations wherein the resin is applied from an organic liquid solution or aqueous dispersion.

Abstract: The invention relates to polyolefin foams consisting of polyolefins of ultrahigh molecular weight, i.e. weight-average molecular weight from about 4 x 10<5> to 6 x 10<6> g/mol and higher, and to a novel process for producing these foams by foaming a solution of a polyolefin of ultrahigh molecular weight in a solvent with the use of a physical or chemical blowing agent or of an inert gas blown into the solution, and cooling of the resulting foam to a temperature below the gelling tempereature of the polyolefin. If appropriate, these foams can be provided wholly or partially with a smooth skin on their surface by superficial cooling, if appropriate under the action of pressure. These foams are distinguished by high tensile strength and impact strength values, shock-absorbing properties, low glass transition temperatures, low embrittlement at low temperatures and high chemical resistance, and they are used especially as mechanical and acoustic insulating materials, materials of construction, filter agents and implantation materials.

Abstract: This invention is concerned with packet switching techniques, protocols, networks, and equipment for use on a local area or wide area scale. Packets which include a fixed-length data field and memory offset field are employed so that packeting, block data transfer to contiguous memory and depacketing can be effected at the destination by hardware-mediated processes with minimal processor involvement. Multiple sessions can be readily handled by assigning addresses to multiple memory buffers at the destination. Thus, each packet carrying computer data provides three levels of addressing for its data segment corresponding to the destination node or device, the memory buffer for the data block being transfered and the memory location within that buffer into which the segment of data carried by the packet is to be placed. The equipment includes loop-based, collision-free packet switches in which packets are modified and re-circulated when a destination is busy. This allows a high-speed loop to transfer packets to and from devices running at various (lower) speeds. Loop latency is minimized and data transfer rates maximized by the use of fully-buffering parallel forms of the switch. A method for handling broadcasts is also disclosed, together with a technique for preempting low priority packets and exploiting short-cuts on a loop. These improvements allow application of the technique to a high-speed voice/data packet-switching in large wide area networks as well as in small local area networks. By using the methods and equipment disclosed, an extensive, powerful and extremely fast integrated communications subnet can be largely built in hardware with little need for processor intervention.

Abstract: The switching P1 regulator has a forward branch and a reverse branch whose feedback output signal is subtracted from the control error in a differencer in the forward branch. A signal corresp. to the desired motion of a control element is formed from the difference result in the forward branch. In the feedback branch a signal corresp. to actual motion is formed from the desired motion signal. A computing element in the feedback branch periodically adds the actual motion signal to the feedback signal and subtracts the product of the feedback signal and the ratio of the controller sampling period to the setting time to form a new feedback signal. This is fed into the differencer.

Abstract: A baggage bin has a floor and side walls, and is lowerable from a housing. Guide bolts secured to one side wall are movably engaged in front and rear arcuate grooves with a common arc center point in the other side wall. A guide roller or slide block secured to one side wall is movably engaged in a linear guide track or groove on the other side wall. To lower the bin, it first moves linearly downward, until the rear guide bolt reaches an end of the rear groove, and then pivots about the rear guide bolt as the front guide bolt moves farther in the longer arc of the front groove, so that the front loading edge of the bin tilts downward. The components are simple, and the lateral space required between the side walls of the bin and the housing is small.
