Patent GB-2140986-A (GB)
Title: Switching of cyclic and general d.c. devices by a self-commutating- avalanche-device or interval-timer circuit
Inventor: HOWARD MICHAEL SHMUEL
IPC: H03K17/292
Filed: 1984-03-27
Abstract: The circuits allow the switching on of a d.c. load for a certain period, which said period is determined either by a time-control means controlling a series-pass means, or by the changing load characteristics of a cyclic load itself which controls a gate-controlled avalanche means; the automatic turning off of said load at end of timing period; the reset of said control means or said avalanche means. Said avalanche means controls cyclic loads, i.e., loads whose current is reduced at or near end of cycle period to below holding current of said avalanche means. Said interval time-control means controls all types of d.c. loads, and may comprise either an RC means, or a monostable means. Both avalanche and time-control means may be used to control a touch-enabled audio-visual canary toy or novelty device. Said avalanche means may be used to turn off a load, such as an indicator lamp, upon change in resistance of sensor, e.g., a thermistor, LDR, etc. <IMAGE>

Title: Measuring current
Inventor: STEWART JOHN STANLEY
IPC: G01R15/22
Filed: 1988-06-03
Abstract: To measure the current flowing through power line (26), a signal induced in a toroid (24) is voltage to frequency converted (30) to form a signal which is applied to a light emitting diode (32). A light signal is transmitted along a fibre optic cable (34) to a detector (36) which drives a frequency to voltage converter (38). The output of the converter is then amplified (40) and applied to an indicator (24). A second toroid (46) is used to provide power for the voltage to frequency converter (30). The system may be incorporated in a gas-blast interrupter (Fig. 1 not shown). <IMAGE>

Patent GB-2219080-A (GB)
Title: Identifying gemstones
Inventor: SMITH MARTIN PHILLIP
IPC: G01N21/62
Filed: 1989-05-05
Abstract: In order to determine whether a particle is a diamond, 514.5 nm laser radiation, moulded at a frequency of 10 MHz to 1 GHz, is projected onto the particle 2, and the radiation emitted by the particle 2 is collected by a wide aperture viewing system 23 with narrow band pass filtering of the diamond Stokes or anit-Stokes Raman frequency appropriate to the laser wavelength. The emitted radiation is detected by a detector 6, and an associated electronic circuit 13, 14, 15 detects signals modulated at the same frequency as the laser modulation frequency. In this way, only Raman radiation is detected as this has a very short rise/decay time; other luminescence forms a background which is not modulated and can be removed by for instance thresholding, or heterodyne techniques. The method can be used to sort diamond from gangue on a wide belt, without very complicated optics. <IMAGE>

Abstract: A liner 30 of polyethylene having a Standard Dimension Ratio (SDR) of 33 or less is pulled through a die 36 and through a pipe 10 and allowed to revert to the internal diameter of the pipe 10. The force of pulling is half the yield strength of the liner 30 or less. The die 36 has an entry 54; a throat 58 and an exit 59, the entry 54 decreasing in diameter towards the throat 58 and the exit 59 increasing in diameter away from the throat 58. The liner 30 has a maximum diameter before the die 36, a minimum diameter at the die throat 58 and an intermediate diameter, due to die swell, after the die 36 (see Fig 5). The throat 58 is defined by the merger in a continuous curve of a radius 56 joining the entry 54 and a radius 60 joining the exit 59. The liner 30 may be pushed (see Figs 6, 7) as well as pulled into the pipe 10. <IMAGE>
