Title: Equipment for single side band multiplexing through digital processing
IPC: H04J4/00
Filed: 1981-07-24
Abstract: Equipment for SSB multiplexing and demultiplexing base-band signals uses the techniques of digital signal processing.

Patent GB-2116464-A (GB)
Title: Drill-grinding machine
Inventor: SCHMID HANS
IPC: B24B3/30
Filed: 1983-03-08
Abstract: A drill (18) to be resharpened is chucked in a clamping chuck (16) of a clamping head (14) so as to undergo either conical grinding or four-surface grinding on the plane surface (48) of the grinding wheel (26). A crank handle (70) serves as a drive element for executing the various movements which are necessary especially for conical grinding. To produce conical grinding, the grinding wheel (26), together with its plane grinding surface (48), remains in one position. If, instead of conical grinding, four- surface grinding is to be carried out on the tip of the drill (18), then two different angular positions between the drill (18) and the grinding wheel (26) are necessary to produce the relief-ground surfaces and the free surfaces for this purpose, the grinding wheel (26), together with its plane grinding surface (48), is pivotable about a pivot axis (B) as a result of actuation of a hand wheel (56). The pivot axis (B) extends over the plane of the grinding surface (48). As a result of such an arrangement, it is possible to carry out four-surface grinding with exact geometry, without changing the setting of the drill. <IMAGE>

Patent GB-2144283-A (GB)
Title: Demodulator
Inventor: BOYD THOMAS
IPC: H04L27/152
Filed: 1983-07-27
Abstract: A demodulator which is capable of demodulating a variety of frequency shifted signals including MSK and FFSK. The demodulator converts an analogue received signal to a digital signal and splits the signal into two quadrature baseband signal streams. The camer frequency of the received signal is derived from the signal streams and clock signals are produced from the derived frequency. The phase of the signal streams is corrected, the phase corrected signals are multiplied by waveforms derived from the clock signals, and the phase corrected and multiplied signals are integrated to provide a data output signal. The phase correction is effected by adding and subtracting the phase corrected and multiplied signal streams and integrating the resultant signals to provide two output signals each indicating the presence or absence of one of the positive and negative frequency shifts in the received signal, and correlating the frequency derived by the non-coherent frequency detector with the two outputs to derive a carrier phase error signal, the error signal controlling correction of the phase. <IMAGE>
