Abstract: The present invention relates to a wave-power aggregate and a method of extracting energy from wave motion in a liquid by means of a wave-power aggregate. The wave-power aggregate comprises a container which is situated at least partially in the liquid and also comprises an inflow and an outflow. The container is arranged to, under the influence of said wave motion, to let a first part of the container arrange itself in a first position and a second part of the container in a second position, where the first and second position corresponds to different potential energy states. The method comprises the steps of: alternately supplying the container with at least a first and a second fluid respectively via the inflow, where the density of the fluids differs. at least during an initial stage of the method controlling a flow resistance in at least one of the first and second fluids through the container.

Abstract: In one aspect, the present invention provides methods of producing conifer cotyledonary somatic embryos from pre-cotyledonary embryos. The methods of this aspect of the invention include the step of (a) dispensing a plurality of pre-cotyledonary embryos onto a porous material horizontally disposed over a non-porous surface in a volume of sterile dilution medium sufficient to submerge at least the surface of the porous material, thereby uniformly dispersing the pre-cotyledonary embryos; (b) removing the sterile dilution medium from the non-absorbent porous material, thereby trapping the uniformly dispersed pre-cotyledonary embryos on the porous material; and (c) contacting the pre-cotyledonary embryos trapped on the porous material with development medium for a period of time sufficient to produce conifer cotyledonary somatic embryos.

Abstract: At least two photoelectric sensors, sensitive to different spectral ranges of incident light, provide two sensed output signals; the relationship of the a-c components of the sensed output signals is evaluated, and it is determined if these a-c components fall within predetermined low frequency ranges, for example, 2 to 50 Hz, preferably 5 to 25 Hz; if so, a "flame present" signal is provided, for example to give a fire alarm, or to indicate that a burner is operating. Preferably, the relationship of the signals is such that a different signal is provided between one of the sensed signals and a fraction of the other, and conversely, and the sensitivity of the sensors is adjusted to have the same output signals at a predetermined color temperature, for example about 1,400 DEG  K. Illumination signals incident on the sensors due to other sources than flames then are reliably eliminated while still providing the "flame present" signal upon coincidence of the appropriate difference signals, which coincidence preferably is determined by analyzing the phase relationships of the resulting difference signals in a phase comparator.

Abstract: This invention relates to fluidized bed furnaces. There is an increasing interest in furnaces in which the fuel is burned in a bed that is maintained in a fluent condition by combustion air supplied to the bed, and a fluid to be heated is passed through heat exchange tubes disposed within the bed. Interest has so far centered on the use of water as the fluid but this presents problems, especially at start-up and shut-down when it can be particularly difficult to ensure that the heat exchange tubes do not become dry and overheated.

Abstract: A flexible self-sealing wall member for fuel tanks has a plurality of thin layers of natural or synthetic rubber which are held together at spaced points by lines of drop thread stitching or by spots of adhesive so that the sheets are free to move across each other between the points of connection. The wall may also include a reinforcing fabric web, an outside barrier layer, and an inside barrier layer, both impermeable to fuel held in the tank of which the wall member forms a part. The wall member is self-sealing when penetrated by a projectile because the rubber layers undergo large dynamic elongations and rapidly recover to close up the holes formed, these holes generally being out of alignment.

Abstract: A process for use in repairing a roadway having an asphalt surfacing 14 in which there is fitted a manhole cover 12, 20, which normally rests on at least one releasably installed fitting element 15 with the manhole cover substantially level with the roadway. Before an outer layer of the surfacing is cut away, the fitting element is removed such that the manhole cover can be lowered to below the level at which the mill-cutting will take place. After this, the manhole cover is raised to the level of the new surface layer by the installation of fitting elements beneath the manhole cover. The new surface layer is subsequently laid on the roadway. A manhole cover for use in the implementation of the process has a cover rim 20, which is placed with a smooth surface 21 at right angles to the end plane of the cover rim. At its lower edge, the cover rim has an inward- facing flange 22 for support against the manhole pipe 18 or against fitting elements 15, 19 lying thereon. <IMAGE>

Abstract: A system for automatically reading meters for commodities such as gas, water or electricity on the consumer's premises and, preferably, producing the bill for payment due at the same time. An external sensor is triggered by indexing movement of part of a conventional meter. A processor, connected to the sensor, has a memory in which the signals are accumulated. The processor includes a card reader and printer which on presentation of a card by the consumer causes the information memorised to be released and transferred to the record card. The record card may have control or command information by which the processor is caused to calculate the total payment due for the quantity of commodity consumed so that the bill is printed and presented when the record card is released from the processor following reading and printing. The processor may be connected to more than one meter, and respective channels with associated memories can be provided for each meter. It is proposed that the record card be prepared by the relevant Authority, posted or delivered to the consumer for postal or like return, and cost savings on labour intensive meter readings can be made. <IMAGE>
