Abstract: A card-edge connector comprising a housing having a circuit-board insertion groove having both ends and formed in the wall face. A contact is fixedly inserted in the contact holes of the housing, so that an end of a circuit board is inserted in the contact. The circuit board is electrically connected to the contact when it is rotated to a position substantially perpendicular to the wall face and is held by the circuit-board holding members of the housing after the circuit board has been inserted slantwise in the circuit-board insertion groove. First lift preventing means and second lift preventing means are provided at the respective ends of the circuit-board insertion groove so as to prevent the circuit board from lifting from the housing.

Abstract: A novel apparatus for catching leaves, trash, yard trimmings or other debris is provided, the apparatus being particularly adapted to catch debris without having to hold the plastic bag or apparatus open by any person. The novel apparatus includes a housing fabricated from plastic, metal or the like, frontal opening for receiving the debris and rear opening of which the edges define a lip and channel where a strap or bag retainer is used to hold a plastic trash or lawn bag to the apparatus so that it will not slip off when in use. The apparatus can also be used as a portable trash can by hooking onto a wall or other forms. In addition the apparatus can be used as a trash receptacle for holding a small amount of debris until a bag can be attached. Finally, the apparatus is provided with attachment for handles of various sizes and shapes for different uses or for the comfort of the person using the apparatus.

Abstract: A chain saw cutting device and method for flush and square cutting walls and other flat concrete surfaces is disclosed. The chain saw cutting device is typically used in conjunction with a track-mounted circular saw cutting assembly, each being removably mounted either on a trolley which rides on, or directly to a track structure, which track structure is attached to the surface to be cut. The chain saw cutting device has an elongated bar and cutting chain which when mounted are positioned in the same cutting line made by the circular saw assembly. The carriage structure of the chain saw cutting device includes a reversible cutting drive and extends on only one side of a cutting plane containing the chain bar and cutting chain. Hence, the chain saw cutting device permits square cutting along the cutting line as well as flush cutting with respect to a perpendicular side wall, ceiling or floor.

Abstract: To interface a primary telephone terminal with a vast number of remote terminals through a telephone network, parties at the remote terminals are individually screened to attain a select group. Bridged together, the select group is preliminarily informed of the status of the interface by a voice generator and, accordingly, the multitude of connections are synchronized for the interface. On cue, the select group is coupled to the primary telephone terminal for unilateral communications. Deviations from the unilateral communication include select bilateral communication for a few of the remote terminals and digital communication from the remote terminals by push button as for polling applications. Subjects for interfaces are programmed for selection from a memory.

Abstract: A task status word (TSW) is created for each task indicating, the instant location of the task, its priority and a record of synchronizing signals. Task status words are accessible from an addressable memory section for delivery to a TSW register. From the TSW register, a selected TSW effects control functions to synchronize tasks in different processors or computational units as well as input-output processors. A physical memory manager locates TSWs in response to signals, then checks the location of the task and the nature of the signal to determine signal routing to a processor. If a task is not in a processor, an interrupt manager resolves priority and signal significance indicated by the TSW to determine an interrupt.

Abstract: A display system is disclosed utilizing a cathode ray display device utilizing three electron beams which are directed through a shadow mask to excite three-color phosphor dots, and which is incorporated in a system to alternately provide raster scan display signals and calligraphic display signals to obtain the benefits of both raster scan and calligraphic displays (dot or line drawings). A deflection unit is disclosed with the X and Y deflection coils each driven by two pairs of transistor circuits. The transistor circuits are controlled so that alternatively one transistor in each set passes current to provide bi-directional currents at desired levels to obtain specific beam displacement. A resistive element between individual deflection coils provides an indication of deflection current, which indication is processed by a differential amplifier to indicate displacement. In accordance with the instant position of the beam, a convergence unit is controlled to reflect spherical considerations.

Abstract: A novel class of compounds, methods for the preparation thereof and the use thereof in chromatographic methods for binding various biologically active materials non-covalently are disclosed. The class of compounds comprises the reaction product of a polymeric gel with a pyridine base, such as 4-dimethylaminopyridine (DMAP), and a halogen-substituted pyridine, such as 3,5-dichloro-2,4,6-trifluoropyridine (DCTFP), which reaction product may in turn be optionally reacted with hydroxyl ions or specified low-molecular-weight compounds. These compounds are capable of selectively and efficiently binding proteins and other organic materials of interest non-covalently to a degree comparable or superior to the heretofore preferred natural affinity ligands, such as Protein A gels. The novel compounds find particular utility in purification and recovery of proteins such as serum albumin and immunoglobulins of various classes from crude sources, such as diluted serum samples from various species.

Abstract: An incandescent electric lamp and a socket for receipt of the lamp. The socket contains an insulator to prevent completion of the electrical circuit for illuminating the filament contained within the lamp except when the lamp has a wattage rating which is equal to or less than the wattage rating for which the socket is designed. When the wattage rating is proper, the central contact assembly of the base of the electric lamp bypasses the insulator to establish a completed electrical circuit. In one embodiment, the insulator defines an opening of a predetermined diameter through which a protrusion on the base of the lamp extends when its diameter is equal to or less than the opening in the insulator. In an alternative embodiment, the insulator has a diameter of a predetermined value while the central contact assembly defines a depression having a diameter which is equal to or greater than the diameter of the insulator.

Abstract: In cooperation with a public telephone network, an automated call processing system incorporates an audio response unit and a computer for effectively relaying calls to a manually attended terminal. Individual calls are assigned unique call reference numbers which are stored along with pertinent information of the call. If a call relay is commanded, the computer actuates a PBX to establish a secondary connection through the telephone network to an attended CRT terminal. Using the secondary connection, the operator at the terminal is given the reference number which addresses the call data fetching it to the terminal for use by the operator. As a final operation, the secondary communication path is bridged placing the operator at the attended terminal in communication with a caller through the original connection established through the audio response unit.

Abstract: In a pipeline computer, current instructions executed in sequence are monitored for conditional and unconditional branch commands, as well as the readiness of condition codes, the meeting of branch conditions and split commands. A branch command initiates an interval of delay which affords prefetching target instructions while using pipeline contents to prevent a pipeline break and avoid lost time. Detection of a branch command actuates a register to store a sequence of target instructions. Unless a branch command is conditional, subsequent detection (delayed) of a split command shifts the stored target instructions into operation as the current instructions. For a conditional branch command, a jump or split to the target instructions is performed only if the condition is met. Otherwise the current instruction sequence is restored pending another branch command.
