US4276653A — Device for receiving radio call messages

Claim 1

Independent Claim 195 words

Device for receiving radio call messages on a ship from different transmitters at different stations, which device comprises a number of receivers (1) for different frequencies from said different transmitters and means for storing and processing the messages received, said device comprising: (A) a shift register means (4) connected to the output of each receiver, (B) an identifier (11) means connected to the output signal, having the value 1 or 0, from said shift register to provide an output control signal with respect to the pertinence of the messages to said ship, (C) a plurality of storing means (13), (D) a switching unit (14) connected to the outputs of said identifier means, (E) said switching unit (14) in response to said output control signal connects the appropriate shift register means to an available storing means (13), (F) a commonly controlled clock generator means for controlling said shift register means, said identifier means, and said storing means, which said clock generator means integrates asynchronously received signals into synchronous signals, and (G) a cyclic scanner (18) for reading out said storing means to one or more terminal stations for further storing and processing the pertinent stored message.

Claim 2

Dependent Claim 195 words

Device for receiving radio call messages on a ship from different transmitters at different stations, which device comprises a number of receivers (1) for different frequencies from said different transmitters and means for storing and processing the messages received, said device comprising: (A) a shift register means (4) connected to the output of each receiver, (B) an identifier (11) means connected to the output signal, having the value 1 or 0, from said shift register to provide an output control signal with respect to the pertinence of the messages to said ship, (C) a plurality of storing means (13), (D) a switching unit (14) connected to the outputs of said identifier means, (E) said switching unit (14) in response to said output control signal connects the appropriate shift register means to an available storing means (13), (F) a commonly controlled clock generator means for controlling said shift register means, said identifier means, and said storing means, which said clock generator means integrates asynchronously received signals into synchronous signals, and (G) a cyclic scanner (18) for reading out said storing means to one or more terminal stations for further storing and processing the pertinent stored message.

Claim 3

Independent Claim 186 words

A device for receiving a plurality of binary radio call messages, said messages being transmitted on different frequencies and at random times, said device comprising: (A) a number of receivers for said different frequencies, (B) an address shift register connected to each receiver having a capacity for a plurality of bits corresponding to the address of the station having said receivers, (C) an identifier means connected to said shift registers to provide an output control signal with respect to the pertinence of the messages to said address-receiving station, (D) a plurality of storage devices for the pertinent received messages, (E) a switching unit in response to said output control signal connects pertinent messages from the appropriate address shift register to an available storage device, (F) a cyclic scanner for reading out the pertinent message stored in said storage devices, (G) a clock pulse generator means for controlling said address shift registers, said identifier means and said storage devices which integrates asynchronously received signals into synchronous signals, and (H) at least one terminal station for further storing and processing the pertinent stored messages from said storage devices.

Claim 4

Independent Claim 186 words

A device for receiving a plurality of binary radio call messages, said messages being transmitted on different frequencies and at random times, said device comprising: (A) a number of receivers for said different frequencies, (B) an address shift register connected to each receiver having a capacity for a plurality of bits corresponding to the address of the station having said receivers, (C) an identifier means connected to said shift registers to provide an output control signal with respect to the pertinence of the messages to said address-receiving station, (D) a plurality of storage devices for the pertinent received messages, (E) a switching unit in response to said output control signal connects pertinent messages from the appropriate address shift register to an available storage device, (F) a cyclic scanner for reading out the pertinent message stored in said storage devices, (G) a clock pulse generator means for controlling said address shift registers, said identifier means and said storage devices which integrates asynchronously received signals into synchronous signals, and (H) at least one terminal station for further storing and processing the pertinent stored messages from said storage devices.

Claim 5

Dependent Claim 14 words

A receiving device according to claim 2 wherein said receivers are on a ship.

Claim 6

Dependent Claim 21 words

A receiving device according to claim 2 including a plurality of identifier means, one for each said receiver's address shift register.

Claim 7

Dependent Claim 24 words

A receiving device according to claim 2 wherein said clock pulse generators for controlling said identifiers and said storage means have the same frequency.

Claim 8

Dependent Claim 45 words

A receiving device according to claim 2 wherein said clock pulse generator for controlling said address shift registers operates at a higher frequency of more than twice that of the frequencies of said clock pulse generators for controlling said identifier means and said storage devices.

Claim 9

Dependent Claim 44 words

A receiving device according to claim 2 comprising a single identifier means, and said clock generators for controlling said identifier means and said storage devices having a frequency several times greater than that of said clock pulse generator for controlling said address shift register.

Claim 10

Dependent Claim 26 words

A receiving device according to claim 2 wherein said clock pulse generator for controlling said address shift registers also controls the other two clock pulse generators.
