Abstract: The present disclosure relates to the use of an aeroponic propagator for supplying fog within an aeroponic propagator for the cultivation of plants. An aeroponic propagator according to the disclosure comprises a fogging system for supplying fog within the aeroponic propagator, wherein the fogging system comprises a droplet generator, the droplet generator comprising at least one outlet, and the droplet generator being configures such that in use each at least one outlet ejects one droplet of liquid at a time.

Abstract: The present disclosure relates to the use of an aeroponic propagator for the cultivation of plants. The aeroponic propagator of the present disclosure may be a human intervention free system. The aeroponic propagator of the present disclosure may allow the total spectrum of all stages of plant growth from seedling to harvest and multi-cropping per system with minimum human intervention. The aeroponic propagator comprises a self-harvesting system for collecting produce from cultivated plants, wherein the self-harvesting system is configures to collect produce that has detached from the cultivated plants.

Abstract: The present invention relates a control system and method for supplying droplets within a space for controlling humidity. The control system comprises a droplet generator and a control unit. The droplet generator comprises at least one outlet and is configured to supply droplets to the space. The control unit is configured to control ejection of the droplets from the droplet generator to control the humidity in the space.

Abstract: Deposits, such as coal, tar sand, heavy crude oil and/or minerals are excavated from an underground formation layer (4) by:—inserting a chain cutter string (11) into a 1st section (8, 9) and a control cable (12) into a 2nd section (10) of a T-, V-, U-, or L-shaped channel assembly (8, 9, 10) traversing the layer (4);—connecting the control cable (12) to the chain cutter string (11) at a branchpoint (13) of said 1st & 2nd sections (8, 9 & 10); and—pulling the chain cutter string (11) in a continuous or oscillating manner through the first section (8,9) while continuously pulling the control cable (12), such that the chain cutter string (11) carves deposits from the layer (4) and the control cable (12) optimizes the performance and reduces the risk of breakage of the chain cutter string (11).

Abstract: A drilling system comprising a pipe comprising a first end and a second end; a drill bit near a first end of the pipe, adapted to drill a hole in a formation; a pipe rotator near a second end of the pipe adapted to rotate the pipe; and a pump connected to the pipe between the first end and the second end, the pump adapted to transport a fluid from the first end of the pipe to the second end of the pipe, the pump comprising a first portion adapted to rotate with the pipe and a second portion adapted to remain stationary relative to the pipe.

Abstract: A rotating and indexing mechanism (10) having two spaced apart, rows of toothed profiles (48, 52) which form camming surfaces for two spaced apart rows (62, 64) of cam followers (32). The toothed profiles (48, 54) and cam followers (32) are such that when there is relative movement between the toothed profiles (48, 54) and the rows (62, 64) of cam followers (32) in one direction, the camming action of the cam followers and toothed profiles pause incremental rotation of a shaft (16). A groove (66) is also provided for locking the two profiles and cam followers together when the desired incremental (index) position is reached.Two embodiments are shown, one where the toothed profiles are moved axially to give rotation to the cam followers and shaft, and the other where the cam followers move axially to give rotation to the toothed profiles and the shaft.
