Patent GB-942970-A (GB)
Abstract: 942,970. Radio receiving circuits. LABORATORY FOR ELECTRONICS Inc. May 1, 1962 [May 1, 1961], No. 16702/62. Heading H4L. [Also in Division G4] In an apparatus for counting the number of axis crossings in a signal, the effects of noise are compensated so that a false count is not obtained. In the embodiment described the incoming signal is mixed in units 14, 18 with reference signals which are in phase quadrature. The resultant signals are fed to filters 15, 19 which give outputs as Fig. 7B, and Fig. 7A, respectively. The signals feed limiters 16, 20 which drive Schmitt triggers 17, 21. Fig. 7D, illustrates the output of trigger 17-the positive parts of this waveform enable gates 24, 25. Differentiating circuits 22, 23 receive the outputs of trigger 21, circuit 22 pulsing at each positive-going crossing of the axis by the input waveform, and circuit 23 pulsing at each negative-going crossing-their combined outputs are as Fig. 7C. The combined output of gates 24, 25 is therefore as Fig. 7E. Unit 26 is a known circuit which gives one pulse for each group of pulses in Fig. 7E, i.e. for each positive-going crossing of the input signal in the absence of noise. These pulses may be counted over a period of time to derive the frequency of the input signal. Unit 26 gives pulses on one or other of two output leads dependent upon whether the input signal has a higher or lower frequency than does the reference signal.

Title: Grommet for an inline fishing lead
Inventor: HODGKISS TERENCE RUSSELL
IPC: A01K95/02
Filed: 1997-05-14
Abstract: A releasable grommet 30 for interposition between two members, preferably an inline lead 12 and a swivel 13, comprises a resiliently compressible tube 32 for receiving therein at least part of the swivel 13 and for fitting into a seat 11a of the lead 12. When the lead, grommet and swivel are assembled, the compression of the grommet is such that it frictionally resist their separation. Thus, glue is not required to hold the members together, and a damaged grommet can easily be removed from the lead when required. The grommet 30 may have a shoulder, 33/34, which abuts a shoulder, 12a/end of seat 11a, of the lead to prevent over-compression. A stem portion 31 of the grommet may fit over and hold in place a protective sheath 16 for the line, thus also negating the need for glueing the sheath 16 to the lead 12.
