Patent GB-2193862-A (GB)
Title: Digital data transmission systems
Inventor: DINGLE CHARLES EDWARD
IPC: H04L5/00
Filed: 1986-08-16
Abstract: A data transmission system uses a control means (10) to allow a secondary data stream from a secondary DTE (14) to be transmitted over a data link (2A, 2B) when the data stream from a primary DTE (6) contains repeated characters. The control means (10) imposes its own protocol on the primary data stream by inserting an additional "0" bit to prevent a sequence of more than five consecutive "1" bits. The primary data stream is passed to a buffer (18) in which sequences of at least a predetermined length of repeated characters are recognised and replaced by control characters including the repeated character, a flag character containing six consecutive "1" bits, and a status and count character which indicates the number of secondary data characters being transmitted. When the data stream is received, flag characters are recognised by a device (38) and this causes the identified repeated character to be sent to the input channel of the associated primary DTE and the secondary data characters to be redirected to a secondary DTE (14). In this way additional secondary data has been transmitted over the data link without affecting the overall length of transmission or the transmission rate used. Monitor 52 ensures that the secondary data mode is not triggered by power failure. <IMAGE>

Title: Zener diode detector circuit
Inventor: TAYLOR JAMES LAURIE
IPC: G01R19/22
Filed: 1987-03-09
Abstract: A rectifier circuit comprises two Zener diodes (3,4) having substantially the same characteristic Zener voltage which are connected to receive a sinusoidal input signal via a low impedance buffer (8). A half-wave rectified signal appearing on line (17) has a DC bias equal to the Zener voltage which is removed by the operational amplifier (15). A low pass filter (20) provides a smoothed DC voltage output on line (21). The circuit may be used as an AC to DC converter or for the detection of signals ranging from several volts down to a few millivolts. Its linear response over a wide dynamic range and at small signal levels is an advantage over conventional silicon diode rectifier circuits which suffer distortion at low signal levels.

Title: Determining average sensor output ratios over both short and long periods
Inventor: ANGELE GEORG
IPC: G01D1/16
Filed: 1987-09-28
Abstract: After integration at 14, the signals 12 from two sensors 13 for different variables are periodically added to the contents of respective stores 21, and integrators 14 are reset. The outputs 27 of the stores are divided at 25 to provide directly a quotient 26 of the integrated outputs of the sensors at least over the short term. For longer periods, every time either signal 27 reaches a threshold 28 at which errors occur, e.g. commencement of non-linear storage (or overflow of a digital store, Fig. 2), circuit elements 29, 30, 34, 38, 43 are operated to divide both stored signals by the same factor and element 35 reduces the inputs to stores 21 correspondingly. Any part of signal 19 not transferred via circuit 35 to store 21 is returned to the reset integrator 14 for the next cycle. Cycle times of integrators 14 may be fixed or (as shown) be terminated whenever a signal 19 reaches a threshold value 23. Applications given are average speed from distance and time, and average fuel consumption over the whole useful life of a motor vehicle. <IMAGE>

Patent GB-2225109-A (GB)
Title: Sorting particles eg diamonds
Inventor: HANSEN JOHN OLAF
IPC: G01N21/87
Filed: 1989-10-19
Abstract: Particles are sorted from one another on the basis of their rotational effect on polarised light. Light from a lamp 12 passes through optical fibre 17 and is plane polarised by polariser 18. A second polariser 32 at right angles to the first prevents light reaching a detector 38 directly. Particles of diamond and gangue 24 fall between the crossed polarisers and only the diamonds cause light to reach the detector 38 by rotating its plane of polarisation. The detector signal is compared with a threshold in comparator 46 and its differential is compared with another threshold in comparator 50. The comparator outputs 47 and 52 are fed via an AND gate 54 to means 62 for ejecting particles 60 which are identified as diamonds. <IMAGE>
