Title: Receiver for Frequency-Modulated Signals
IPC: H04B1/28
Filed: 1966-12-30
Abstract: 1,163,330. Frequency modulation receivers. INTERNATIONAL STANDARD ELECTRIC CORP. 30 Dec., 1966 [31 Dec., 1965], No. 58357/66. Heading H3R. In a superheterodyne receiver for frequencymodulated signals having a predetermined maximum frequency shift, the I.F. amplifier is tuned exclusively by RC filters and operates at a frequency less than five times the maximum frequency shift, suppression of image frequencies being obtained by limitation in the I.F. amplifier. The demodulator is preferably a monostable circuit feeding an integrating capacitor, and the demodulated signal may be fed back to control the local oscillator frequency thereby providing negative feedback and automatic frequency control. Switch means may be provided for altering the sign of the feedback so that the local oscillator can be stabilized at will on either side of the input frequency. The receiver may be constructed as an integrated circuit.

Title: Document copying apparatus
IPC: G03G15/043
Filed: 1973-12-21
Abstract: 1452490 Document copying apparatus XEROX CORP 21 Dec 1973 59539/73 Heading G2A In a photo-copying apparatus which operates on the scanning principle, the intensity of the light source is adjusted according to the reflectance of the original, as determined by a preliminary scan. Fig. 1 shows an electro-photographic copying apparatus of the type disclosed in Specification 1436899, in which the light source 15 and mirror 12 scan across the document 11 which is being copied, the light eventually being reflected on to a rotating photo-receptor 18. A slit 19 in a coverplate 20 limits the image field and compensates for the uneven light distribution from the lamp 15. In order to adjust the intensity of the lamp to a suitable value, a preliminary scan is carried out. A light intensity detector 21 (of which there may be more than one) is mounted on the plate 20. The output from detector 21 is compared with a predetermined reference voltage, and the resultant led to a memory capacitor and a lamp drive circuit (35, 37), Fig. 3 (not shown). If the detector voltage is higher than the reference voltage, the current to lamp 15 is automatically reduced until these two voltages are equal, after which the capacitor ceases discharging. Instead of controlling the illumination intensity, the same effect may be obtained by controlling the width of a slot in the optical system.

Title: Apparatus for positioning an off-shore gravity structure on a previously positioned sea bed unit
IPC: E02B17/02
Filed: 1978-11-02
Abstract: Apparatus is described for positioning an off-shore gravity structure on a previously positioned sea bed unit during lowering of the gravity structure onto the sea bed. A sea bed unit 4 comprises a unit template surrounded by a guide structure in the form of a perimeter frame. The gravity structure comprises a base caisson (1) of reinforced concrete and at least one hollow reinforced concrete tower (2) projecting upwardly therefrom for supporting a work deck (3) out of the water. The apparatus comprises: -co-operating contact means provided on the sea bed unit and in a sea bed unit receiving recess (8) in the lower surface of the base caisson (1), and -a plurality of anchors (5) for location on the sea bed around the sea bed unit and for fixing to the sea bed independently of the sea bed unit, and co-operating winch means (7) connected to the anchors by cable 5. During lowering, progressively more accurate guide systems are used. The winch means enable the recess (8) to come into contact with the guide structure surrounding the template. Camming action between the guide structure and the rim of the recess brings the gravity structure very near the required alignment, and finally camming between elements on the template and co-operating elements in the recess completes the procedure, without at any time having to apply undue stress to the sea bed unit. Guideline (9) lead from the sea bed unit to tension- limiting winches (10) on the work platform (3) for guide purposes, but the limiting tensions are set so that little force is transmitted from the structure to the sea bed unit via the guidelines. <IMAGE>

Title: Methanol from Synthesis Gas
IPC: C01B3/14
Filed: 1979-05-10
Abstract: Methanol is produced from a carbon monoxide stream by reacting carbon monoxide with steam in a catalytic shift reaction, removing any excess steam and at least part of the carbon dioxide from the shifted gas, reacting the resulting gas over a copper-containing methanol synthesis catalyst at under 300 DEG C, heat exchanging reacted synthesis gas with water under pressure and bringing the resulting hot water into direct heat exchange with the carbon monoxide stream to provide steam for the shift reaction. In a preferred process the carbon monoxide stream is freed of non-refractory sulphur compounds before the shift stage and the refractory sulphur compounds are converted in the shift stage to H2S, which is removed with the carbon dioxide.

Title: Fire Resistant Valve Seat
IPC: F16K1/226
Filed: 1979-07-31
Abstract: The valve includes an annular shoulder 42 that is disposed adjacent an annular seat; and an annular collar 44 of substantially incombustible corrosion resistant, nongalling material is mounted on the shoulder, the collar including a first portion 46 hermetically connected to the shoulder and a second lip-like portion 48 free to move with respect to the shoulder and normally spaced from the selectively positionable valve element 26. This collar and specifically the lip portion thereof is provided with prestressed regions normally situating the lip portion proximate the body shoulder and in position wherein said lip portion will not interface with the movable valve element. Upon thermal relief of the stresses stored in such regions, the collar reacts to dispose the lip portion into sealing engagement with the valve element when in the flow aperture closing position. This stress relief is permanent, such that upon subsequent cooling of the valve the collar lip portion will remain in sealing engagement with the valve element, thereby preventing leakage, even though the primary seal 32 may have been destroyed by the thermal event. <IMAGE>
