Title: Fluid flow valves
IPC: F16K1/12
Filed: 1973-12-21
Abstract: 1494734 Valves NORMALAIR-GARRETT (HOLDINGS) Ltd 11 Dec 1974 [21 Dec 1973] 59619/73 Heading F2V A valve has a valve-head 13 movable axially in a straight part 11 of a flow passage to control flow therein, the valve-head having an elongate member 14 extending therefrom and forming the closure of a valve in a conduit 27 connected to the flow passage. The conduit 27 may be connected to the flow passage downstream of the valve-head as shown in Fig. 1 so that the downstream space is vented when valve-head 13 is in sealing contact with seat 19. Alternatively the conduit (66), Fig. 2 (not shown), may be open to the upstream region and opened when spindle (52) is spaced from seating (68), to a pressure sensitive device (65) to give indication of valve-head position. The valvehead 13 is moved to close by a spring 24 when pressure balance across it is established through valve 26 and vice versa. A modulating valvehead 29 and actuating piston 30 are operable to operate and control the flow rate when the valvehead 13 is open.

Abstract: 1413840 Copying by scanning NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and NIPPON ELECTRIC CO Ltd 27 Dec 1972 [24 Dec 1971 (2)] 59660/72 Heading H4F A combined facsimile transmitter and receiver is operated to transmit a signal derived from an original 28 and/or reproduce on medium 29 a copy of original 28 or a copy corresponding to a received signal, the original 28 and medium 29 being fed by respective motors 23 and 24 and co-operating rollers 21, 26 and 22, 27. The apparatus includes a disc 12 rotated by a motor 15 via a worm wheel 13 and shaft 11, the disc carrying three styli 46 to record on medium 29, original 28 being held spaced from disc 12 a sufficient distance so as not to be contacted by styli 46. The signal received at 49 is fed to the stylus 46 which is in contact with medium 29 via an electrical contact 48 and one of three contacts 47 on the disc, each contact 47 being connected to a respective stylus 46. To derive the signal from original 28 for transmission there may be included a light source 31 and photodetector 32 with associated optical fibre bundles 41, 42, light source 31 and photodetector 32 either being on the same side of disc 12, as shown, or on opposite sides of disc 12. A blackout member 45 may be provided to prevent pick-up of reflections from recording medium 29. The end of each optical fibre bundle 41 transmitting light to the original 28 may be bevelled to direct light on to the point on original 28 viewed by the end of the respective bundle 42, which may be provided with a condensing lens (51, Fig. 2, not shown). Alternatively optical fibre bundles 41 may be omitted, light from the light source being transmitted via lenses supported in a tube surrounding each optical fibre bundle 42 (Fig. 5, not shown), the end of each bundle 42 also being provided with a condensing lens, the light being passed to the tubes from the light source either directly or via a mirror. The apparatus may include a microswitch to detect the presence of an original 28, detection of an original 28 causing operation of an electromagnet (75, Fig. 3, not shown) to move a guide (54) holding recording medium 29, to move medium 29 out of contact with the recording styli 46 and to separate feeding rollers 22 and 27 so as to stop feeding of medium 29. Reference has been directed by the Comptroller to Specification 1,088,288.

Title: Servo aided injection phase-locked laser oscillator
IPC: H01S3/098
Filed: 1970-12-21
Abstract: 1,272,726. Lasers. UNITED AIRCRAFT CORP. 21 Dec., 1970 [20 March, 1970], No. 60510/70. Heading H1C. A high power laser generator, shown as a ring laser in Fig. 1, is phase locked to a spectrally pure reference laser 10. The resonant frequency of the ring cavity is automatically adjusted by moving mirror 14 until it is substantially the same as the reference laser frequency, so that a high power beam is obtained at the reference frequency. The reference beam is injected into the ring through mirror 12, an arrangement which prevents feedback into the laser 10. The main laser 18 is a gas tube supplied with a constant pumping current by source 40. Mirror 14 is mounted on a transducer 22 fed with a dither signal from an oscillator 30, and the resonant frequency of the ring is thus varied. This causes a variation in the gain of the ring laser at the reference frequency, and consequently a small variation in the output power. A variation is thereby produced in the impedance of the pumping discharge plasma, so that an alternating voltage appears across the discharge. This is fed via capacitor 42 to a synchronous detector 26 which drives amplifier 24 to adjust mirror 14 until the output power is maximized. The reflectivities of the mirrors of the ring are such that the main laser cannot produce a fully saturated output on its own; this permits the main laser to phase lock to the reference input beam, Fig. 2 (not shown). When phase locking occurs, the dithering of mirror 14 does not vary the frequency of the output 20. The ring may contain more than one laser active medium, e.g. others may be placed at 16, 17, Fig. 1. Refracting or diffracting devices such as prisms or gratings may replace one or more of the ring mirrors. The ring laser may be used as the reference source, and a Fabry- Perot oscillator used as the main laser.

A radial-ply pneumatic tyre 10, having at least one radial ply 11, includes a substantially inextensible tread-reinforcing belt disposed over the crown region of the carcass and composed of a plurality of generally sidusoidal windings of a tape of rubberized inextensible parallelcords, the peaks of the sinusoidal waves being tangential to the edges of the completed belt 14, and the half wavelength of the waves being not greater than a third of the circumference of the completed belt. The latter comprises, at least, two layers of windings of tape 14a, the windings as shown in Fig. 2, being successively staggered and having overlapping edges to give a belt which is thicker at its edges than in the middle, the preferred half wavelength being 1/12 to “ of the circumference. Preferably, the tape is # inch wide and comprises 10-20 cords per inch of width. The tyre may be made by providing the carcass in a substantially torroidal configuration and forming the belt by winding the tape while simultaneously rotating the carcass about its axis and oscillating it about an axis perpendicular to the axis of rotation. The belt may be pre-formed in a cylindrical former and then applied to the carcass.

Abstract: The amount of vitamin B12 in solution in a liquid is determined by mixing a sample of the solution with vitamin B12-binding proteins from chicken serum in a pH of about 12.8 to 13.2, and then analysing a component of the mixture. In preferred procedures, especially useful in assaying human sera, a competitive binding technique is employed utilizing labelled vitamin B12 and a buffer containing cyanide ion.
