Selected program code and time data entered into a subscriber command terminal automatically establishes a two-way telephone link with a library computer from which instruction data is transferred to the command terminal for subsequent programmed reception and reproduction of broadcast signals by a standard receiver coupled to the command terminal. The broadcast signal originates at a library of program records linked by a one-way broadcast transmitter to a plurality of the subscriber command te...

This disclosure illustrates and describes an electronic program control for controlling the filling operation for cartons supplied by one turret mechanism having a plurality of equally spaced mandrels to a compartmented conveyor which carries the cartons in pairs beneath a pair of filler nozzles. The electronic program control includes the switches, AND gates, shift registers and flip flops required to assure that, in the event a carton is missing for any reason from a conveyor compartment, the ...

The following specification sets forth a magnetic media and program storage case that is formed substantially from a single injection molded container. The injection molded container is formed with two major faces or covers and a binding or spine therebetween having a living hinge holding said major covers. An end closure or flap is hinged to one of the major covers by a living hinge. The flap incorporates tabs having tangs or barbs thereon for insertion within openings within the edge region of...

An arrangement for the support of a program plate, preferably for a timer, including a bottom plate with a support sleeve fastened thereto and which is preferably integrally formed with the bottom plate; in which the outer surface of the support sleeve forms a rotary bearing for a hub of the program plate. The bottom plate includes a hole breakthrough which forms a guide for a drive take-off pinion of a driving mechanism for the program plate which is located below the bottom plate, and wherein ...

Telephone selection signals are conducted through a separate signal path to a program selector at a remote program storing station from which program readout signals are conducted, after the telephone link is broken, to a signal carrier transmitter. A message signal is inserted during a timed message period, after which program transmission begins and is registered by a billing computer.

An apparatus for making available to a calculator remote programs provided on memory chips and transferring the data stored in the chips into the calculator using only the power supply of the calculator. A connector extends between the calculator and the apparatus for supplying a chain of clock pulses from the calculator for controlling the transfer of data between the apparatus and the calculator. The EPROM chips are temporarily turned on with power generated by the power supply carried in the ...

A mechanized system distributing the access, test and communication functions to the point of testing, typically the centralized switching facility serving the telephone loops and equipment to be tested. Computer (200) stores information about each subscriber loop in the geographical area served by a system. Front-end computers (220,221) interact with computer (200) to retrieve pertinent data regarding loops to be tested. Each switching facility in an area includes a loop testing system (e.g., 1...

A single-chip microcomputer device contains on-chip program storage in a read-only memory (ROM), and this program may be corrected or updated by patching. The ROM addresses are applied to an off-chip memory device containing one bit for each potential ROM address, and each bit is set to mark the beginning address of code to be patched; an interrupt is signalled when one of these set bits is accessed by an address occurring during operation of the microcomputer. The interrupt causes the processor...

The program circuit according to the present invention can apply a program voltage to the only memory cells which are not programmed during a re-programming operation, thus, the present invention can be prevent a lowering of reliability of the memory cell due to a continued supply of a program bias voltage.

An arrangement and method of inactivating dynamically an exit in a computer system. An exit is a program module associated with a first program and which is invoked while active by a second program in response to the occurrence of a prescribed system event. When a request to inactivate exit is received, it is determined if one or more invocations of the exit are in progress or scheduled. If an invocation of the exit is not in progress or scheduled, the exit is marked as inactive. However, if one...
