Title: Hydraulically-driven pump
Inventor: HOYA TAKESHI
IPC: F04B43/107
Filed: 1986-12-19
Abstract: Fluid such as an industrial waste slurry is pumped in a pumping chamber 2 by alternate expansion and contraction of membrane 1. This is produced by the reciprocators of piston 23 transmitted by oil column 5 to telescopic member 15. Piston 23 is linked by rod 24 with another piston 28 in another hydraulic cylinder 26. This second piston is reciprocated by alternately feeding pressurised oil to and draining oil from each of ports 31, 31' in turn, under the control of changeover valve 34. <IMAGE>

Title: Method of tempering edible compositions
Inventor: GROEN JOHN WILLIAM
IPC: A23G1/18
Filed: 1987-02-02
Abstract: A method of tempering edible fatty compositions such as chocolate involves controlling the temperature of the composition to a predetermined temperature, passing the temperature-controlled composition continuously through a heat exchanger (102) monitoring the consistency of the composition being discharged from the heat exchanger (102) and using this to control the cooling of the composition in the heat exchanger (102). Monitoring of the consistency may be affected by monitoring the pressure difference across the heat exchanger (102) using pressure transducers (114) and (116), or it may be effected by other means such as monitoring the motor used to effect mixing of the composition in the heat exchanger or by use of an in-line viscometer.

Title: Optical communications systems
Inventor: BYRON KEVIN CHRISTOPHER
IPC: H04B10/2507
Filed: 1989-11-15
Abstract: Soliton-type interaction is eliminated in optical fibre communications system by making the fibre appear to be a passive optical pipe to a signal to be transmitted along it. In particular, the signal to be transmitted is intensity modulated and at a first wavelength  lambda s which is greater than the minimum dispersion wavelength  lambda o of the fibre by a predetermined amount. This signal is launched simultaneously into the fibre with a signal of dark pulses of the same format at a wavelength  lambda c less than the minimum dispersion wavelength by the predetermined amount. As a result the light transmitted in the fibre is of constant intensity and soliton-type effects, which rely on intensity variation for their formation, do not occur. The wavelengths  lambda s and  lambda c may be reversed. <IMAGE>

Title: Instrument for displaying relative positions of astrological or astronomical features
Inventor: BURNETT-STUART GEORGE CLEMENT
IPC: G09B27/00
Filed: 1990-02-02
Abstract: The instrument comprises a plurality of rotatable annular indicator wheels (2A-2H) each carrying a representation of a given astrological or astronomical feature, e.g. the sun, moon, planet or stars, and driven independently by stepper motors (6) under the control of a computer. The complicated movements of the astrological features relative to the earth can thus be calculated electronically and a simple drive mechanism used to move the indicator wheels (2A-2H). By updating the position of the indicator wheels (2A-2H) at regular intervals, e.g. each minute, the instrument functions as an astrological clock. <IMAGE>

Title: Device for measuring intensity of plant organ gas exchange in an air flow
Inventor: DAVYDOVICH TON JURY
IPC: G01N33/497
Filed: 1988-09-01
Abstract: A device for measuring the intensity of plant organ gas exchange in an air flow comprising a chamber constituted by two hingedly interconnected flaps (1), the internal volume of which is connected by means of a flexible tube (12) and through an air pump (16) to a gas analyzer (17). The device is provided with a drive for moving the flaps (1), consisting of a bellows (7) mechanically connected to the flaps (1). The bellows chamber is connected to the tube (12) on its section between the chamber and the air pump (12), whereas a throttle (15) is mounted in the tube between the connection points of the chamber and the bellows (7). When the tube (12) is connected to the air pump (16) a vacuum inside it actuates the bellows (7) whose contraction leads to closing of the flaps (1) of the chamber when sampling the air for the analysis. When the pump (16) is disconnected the flaps (1) of the chamber adopt the closed position, thus causing minimum disturbance to the thermal regime of the analyzed object. The device may be transformed into a multichannel one by means of a switch (20).

Title: A method and arrangement for installation of a well template on the sea floor
Inventor: EVJE HANS ARNE
IPC: E21B43/017
Filed: 1991-04-29
Abstract: In a method for assembling a well template (3) on the sea floor (8) a protective structure (1) is first placed on the sea floor. The well template (3), which fits into a central opening in the protective structure (1), may either be lowered down together with the protective structure or in a subsequent separate operation. By means of for example jacks (2) the well template (3) is levelled and secured relative to the protective structure (1) while casings (13) are brought down and into the sea floor through well slots (14) on the well template (3). The upper end of the casings (13) is connected to the well template (3) to form well heads (6). The well template is now held by the casings (13), whereupon the connection (2) between the well template (3) and the protective structure (1) is released thus allowing the last-mentioned to undergo settings or other kinds of smaller movements without this leading to forces acting on the well template. Also shown are several examples of submarine installations utilized in the method.
