  • Patent number: 4870566
    Abstract: A communications concentrator and message multiplexer featuring direct access from the communications adapters to main memory via direct memory access means which eliminates the usual scanner or polling facility in a concentrator or multiplexer is described. A control microprocessor manages the allocation of memory, the conversion of message protocols and the servicing of interrupts to a plurality of port interface adapter microprocessors. The interface adapter microprocessors directly set up and control the DMA operation instead of having the DMA operation controlled by the control processor. One of the port adapters serves as a service adapter over a dedicated interface allowing a remote disgnostician access to internal registers in the control processor system, access to a dedicated read only storage for servicing, and logical interface to the main control processor for the purpose of entering instructions and directing functional operations to test each component of the system.

  • Patent number: 4841674
    Abstract: A portable impact-resistant athletic numerical indicator display produces highly visible numerals for observation by athletic participants and spectators. The display is provided with a series of shiftable component numeral panels which are connected to a selector lever by a coupling device including a stationary, slotted bar and yoke. The desired numeral to be displayed is presented behind a transparent face in the body by shifting the corresponding selector lever from a first position to a second position to compose the numeral to be displayed from the component panels. The display is conventionally used in contact sports such as football and is constructed to withstand impact with a player or the ground. The display is preferably mounted on a pole and is provided with a layer of padding to protect the playes from injury.

  • Patent number: 4745600
    Abstract: A technique for regulating the transmission of messages initiated simultaneously by a plurality of nodes of a network, in which clock intervals are established for the network, a sequence of digital values is included in each message and is transmitted to the medium at the rate of one digital value per clock interval, the sequences included in messages that are initiated at the same time by more than one node are transmitted in the same sequence of clock intervals, the presence on the medium of a selected digital value during any clock interval in which a node is transmitting a different digital value within the sequence of a message is detected, and the transmission of the message is interrupted by the node upon such detection, without corrupting another node's transmission.

  • Patent number: 4637191
    Abstract: A roofing shingle having its lower edge portion vertically slotted to divide it into a series of tabs, the shingle being configurated to permit easy breaking of the tabs from the upper part of the shingle, and having a horizontal strip of heat-sensitive adhesive applied to its upper surface on a line above the upper ends of its slots, the upper portions then being usable to form a course of starter shingles along the eave edge of a roof deck to provide an uninterrupted shingle beneath the slots of a course of standard shingles applied over the starter course, with its adhesive strip positioned to seal down the tabs of the first course of standard shingles, and the separated tabs being usable to simulate a course of topping-out shingles adjacent the ridge of the roof. The top surface of the shingle is also configurated to drain water away from the nails used to secure it in place, to inhibit leakage of water through the nail holes in the shingle.
