Articles to be weighed are supplied to the dispensing feeder 4. From...

A combinational weighing device comprises a plurality of weighing cells and corresponding associated weighing hoppers (W.sub.1 . . . W.sub.10) and an outlet-side transfer device (5) for supplying weighed products into a package to be arranged therebelow. In conventional manner a controller (6) has an input connected with the output of the load cells and an output connected to respective drives for the closable outlets of the weighing hoppers. The drives of the outlets of the weighing hoppers are...

A compact combinational weighing apparatus comprises a compact housing structure for weighing devices and a remote control unit which are connected only by an elongate signal-transmitting cable. Inside the housing are a number of article batch handling units disposed in a linear array. Each article batch handling unit includes a pool hopper of a double-gate structure for receiving an article batch from an article feeder and two weigh hoppers for weighing received article batches. The article bat...

A combinational fireplace arrangement has a plurality of log-shaped members having a hollow center portion with passageways through the bottom thereof for permitting air to pass upwardly through the log-shaped members into the hollowed center portion thereof. The log-shaped members also have a plurality of holes extending through the upper portion thereof from the hollowed center. A spiral shaped tube passes serially through each of the logs which tube conveys a fluid, such as water, through the...

A combinational air blower and exhauster includes a case including a blowing chamber and an exhausting chamber engaged with the blowing chamber, the blowing and exhausting chambers being each provided with a spring-loaded pin at the central portion of an outer end thereof, and an impeller disposed within the case, whereby the combinational air blower and exhauster can be conveniently used as an air blower or exhauster as required.

The present invention relates to a combinational logic circuit including at least a pair of inputs and an output line; at least a first module and a symmetrical module; the first module including a parallel cell and a series cell; the parallel cell including two switches controlled by the pair of inputs and in parallel between a supply terminal and an output terminal coupled with the output line; the series cell including two switches controlled by the pair of inputs and in series between the su...

A method for the synthesis of multi-level combinational circuits with cyclic topologies. The techniques, applicable in logic synthesis, and in particular in the structuring phase of logic synthesis, optimize a multi-level description, introducing feedback and potentially optimizing the network.

A programmable logic circuit for deriving any selected combinational logic function of a plurality of input logic signals, a particular logic function being established by programming signals supplied to the logic circuit. The circuit is a branching tree structure of successive gating levels, each gating level receiving a respective input logic signal and including one or more pairs of logic switches, each such gating switch being a bipolar transistor or a CMOS pair. Each pair of gating switches...

A unipolar, RZ, constant width pulse telemetry is achieved in the combinatorial set, or any desired subset of pulse sequences thereof. Each input datum W is in one-to-one correspondence with a particular pulse sequence and the correspondence of datum with pulse sequence and vice versa is implemented by any selected ordering of the pulse sequences of the combinatorial set together with a successive comparison of the magnitude of the datum with the cumulative combinatorial capacity of the set.

A scheduling aid is provided that permits extremely rapid selection of a required number of combinations from a given field of choice, as a logic process enhancement. The scheduling aid can be operated in regards to numbers, such as making lottery selections or for making up work schedule and similar organizational activities. In the matter of lottery number combinations the system makes possible the generation of a total or a partial series of combinations of a predetermined number of choices f...
