Patent GB-2170928-A (GB)
Title: Optical fibre splicing
Inventor: ANDREWS PATRICK VASSAR
IPC: B23Q15/24
Filed: 1986-01-29
Abstract: In effecting axial alignment of the cores of two optical fibres by injecting light from a source of predetermined intensity into the core of one of the optical fibres at a position adjacent the proposed optical fibre splice, the intensity of light transferred into the core of the other fibre is monitored by detecting a signal produced by light extracted from the core of the other fibre at a position in the other fibre adjacent the proposed splice and the signal is amplified to lie within a predetermined range of strengths by means of a variable gain amplifier, one or each of the fibres being automatically transversely moved with respect to the other in accordance with the detected amplified signal until the signal is a maximum. The variable gain amplifier may be manually adjusted but, preferably, amplification of the signal by the variable gain amplifier is automatically effected. The method is applicable to single and multi-mode optical fibres, single mode optical fibres with a "depressed" cladding, and all such optical fibres when carrying a buffer coating which is not removed at the positions at which light is injected into and extracted from the optical fibres. <IMAGE>

Patent GB-2188208-A (GB)
Title: Hearing aid amplifier
Inventor: KILLION MEAD C
IPC: H03F3/217
Filed: 1986-04-14
Abstract: A sub-miniature power amplifier for hearing aids configured to be completely self-contained and to fit within the user's ear wherein, in response to the absence of signals from the hearing aid microphone, a power amplifier provides a train of alternating positive and negative electrical pulses having substantially zero average value at an ultrasonic frequency. A class D amplifier stage may provide a peak-to-peak output voltage greater than the power supply voltage. By configuring all signal elements as digital units, circuit balance is readily maintained. A substantial economy of battery drain is achieved while preserving a low value of distortion at low signal levels. Oscillator frequency is governed by a single resistance element. An optical efficiency-improving inductor can also be accommodated entirely within the residual volume of known earphone housings. <IMAGE>

Title: A mud saver valve sub
Inventor: REDDOCH JEFFERY A
IPC: E21B21/10
Filed: 1986-04-15
Abstract: A kelly mud saver valve sub 10 is provided having a tubular valve body 12 with an annular seat 18 fixed in the interior of the valve body. A tubular closure member 22 is reciprocally mounted within the valve body, and is biassed with a helical spring 38 into a closing relationship with the annular seat. Unidirectional seals 40, 44 are provided around the closure member to form a chamber 34 in which the spring is retained, the unidirectional seals permitting fluid only to leave the chamber but not enter it. Spacer rings 32, 33 are provided at the downhole end of the chamber to prevent downhole pressure from being communicated past the spacer rings. The closure member in the valve accordingly opens solidly under the force of hydraulic pressure since the pressure acts against a larger area of the uphole end of the closure member than of the downhole end. <IMAGE>

IPC: C23C14/28
Filed: 1990-04-24
Abstract: There is provided a reaction gas supplying means for locally supplying a reaction gas to the light eg laser beam focussing point on a target. Thus, the reaction gas can be effectively supplied to the target, and only a small quantity of the gas need be used thereby improving the quality of a thin film eg. of a ceramic to be formed. A nozzle 21 covers light transmitting member 11 and a gas introducing means 23 is connected to the nozzle. Thus, also, tho vapor generated by the target is prevented from adhering to the light transmitting window, and the light transmitting window can be kept clean. Alternatively the reaction gas may be ejected directly to the target (Fig. 7 not shown).
