IPC: B29C49/46
Filed: 1979-07-21
Abstract: A method of and apparatus for making an article from a thermoplastics material.

Patent GB-2072463-A (GB)
Title: Speech and data communication network
IPC: H04Q11/04
Filed: 1981-03-11
Abstract: The network comprises a two-wire bus (coaxial cable 10) and a source of synchronizing pulses connected to the bus for marking off TDM cycles of about 125 mu s duration comprising a control slot and 8 links, i.e. pairs of time slots. The bus links devices, each comprising a microprocessor 30, TDM interface 32, bus interface 33 and audio circuits 34. To set up a call the calling microprocessor finds a non-busy link and addresses in the control slot the called device which acknowledges. The TDM interface of the called device transmits pulses in one slot of the selected link while the TDM interface of the calling device transmits pulses in the other slot of the selected link. The bus interface effects pulse width modulation and demodulation of the pulses for full duplex speech transmission. The microprocessor also sends and receives digital data by the omission of pulses representing 0 bits. The data is formatted in 8-bit bytes framed by single 0 start and stop bits separated by guard bits, so that the longest possible interruption to speech transmission is 10 TDM cycles, i.e. about 1 ms. This is short enough to allow simultaneous transmission of speech of reasonable quality and low rate digital data (e.g. from a keypad). High rate data, e.g. 4800 baud can be transmitted in full duplex with worse degradation of speech which is not however likely to be required simultaneously with high rate data transmission. <IMAGE>
