Title: Roof bolt grouting
IPC: B28C5/06
Filed: 1982-05-04
Abstract: A mine roof bolt grouting system (Fig. 1, not shown) includes a mass-flow bin (24) for storing a dry cement powder with a screw feed (27) for accurate metering of a uniform flow therefrom that is transported pneumatically for mixing with water in the throat of a venturi mixer (42). From the venturi mixer, the system provides for a transfer of the wet grout entrained in an air flow onto an internal fin arrangement 60 of a grout delivery tube 21, Fig. 2, to spin the wet grout in a helical flow pattern, that flow travelling into a connected inverted inertial separator 22 wherein the wet grout is separated from the transporting air flow, which air flow is vented to atmosphere through a vortex tube 57 arranged in the grout delivery tube, the wet grout discharged from the internal separator into a hole 23a drilled in a mine roof (23). The grout delivery tube mounting the inverted inertial separator is arranged to be withdrawn from the hole as it fills. <IMAGE>

Abstract: A screening arrangement for preventing radio frequency interference from and between a number of individual sub-circuits is in the form of a unitary walled structure 8 made up of integral electrically conductive walls 11 which define a plurality of compartments 12 each open at both ends. A printed circuit board 10 has a pattern of conductors formed on its upper surface matching the pattern of the walls 11, and a similar pattern of conductors on its under surface, the upper and lower conductors being electrically connected by means of plated-through holes. The printed circuit board 10 is fixed to the underside of the wall unit 8 so that the pattern of conductors on its upper surface are in contact with the walls 11 and the corresponding conductors on its upper surface are in contact with lands or ridges 14 on a base 5 which is screwed through the board 10 to the wall unit 8. The sub-circuits are formed on the board 10 so as each to lie inside a respective one of the compartments 12.

Title: An irrigation system for plants
Inventor: HARRIS PHILIP STEPHEN
IPC: A01G27/04
Filed: 1983-01-28
Abstract: In an irrigation system for plants, the wetness of a sub-irrigation layer 10 is controlled by sensing the level of water in a relatively small sump 13 set a few centimetres below the sub- irrigation layer and connected thereto by means of a wick 15. When the sub- irrigation layer is wet, water flows from the layer into the sump and vice- versa. One form of sensing means is a float 16 in the sump and attached to the control arm of a water supply valve 19 feeding a water distribution arrangement. A preferred distribution arrangement consists of a plurality of mutually spaced wells 23 upstanding from the sub-irrigation layer. These wells are supplied from a low-head reservoir in turn supplied by the above mentioned supply valve. Water in each well is transferred to the sub- irrigation layer by means of a wick 28. <IMAGE>

IPC: H02K1/12
Filed: 1983-06-14
Abstract: A multi-pole stator for an electric motor comprises a number of pole- pieces 1 with pole shoes 2 and a number of wedge pieces 5 between the pole pieces. Each of the pole pieces and wedge pieces is formed from a stack of ferro-magnetic laminations and the stator is assembled by inserting each of the pole pieces 1 through a coil, one of which is shown at 11, and then holding the pole pieces accurately in position by means of an electro-magnetic mandrel 13 having ridges 14 by which the pole shoes 2 are held at the required spacing. The wedge pieces 5 are then inserted. Owing to the tapering of the side faces of the pole pieces 1 and the end faces of the wedge pieces 5 there is satisfactory metal-to-metal contact between the wedge pieces 5 and the pole pieces 1 so that the magnetic flux path is not interrupted. The assembly of pole pieces and wedge pieces 5 is surrounded by an extruded aluminium tube 7 and the clearance space 9 is then filled with epoxy resin filler. <IMAGE>

Title: Doppler radar systems
Inventor: KNIGHT RODERIC LESLIE
IPC: G01S13/56
Filed: 1983-10-18
Abstract: A radar system, for instance for controlling traffic lights, comprises a transmitting diode 21, mixing diodes 22, 23 for mixing the transmitted and Doppler shifted echo signals to produce first and second beat signals whose frequency is indicative of the speed of the target and whose relative phase (detected by phase detector 8) depends on the direction of movement. A timing circuit 10 inhibits normal operation of the phase detector 8 when the frequency of the beat signals is indicative of a target speed outside a certain range, and thus enables false triggering of the system to be minimised (for instance by pedestrians). <IMAGE>

Title: Suspended ceiling system components and assemblies
Inventor: DANIEL CECIL DILWYN
IPC: E04B9/06
Filed: 1984-06-14
Abstract: This invention relates to trims for suspended ceiling components and to assemblies including such trims. As can be seen in Fig. 1 a trim 11 is suspended from a grid component 10 to provide an acceptable cheap visual surface. The trim has an upwardly extending recess 15 which is dimensioned so that it contacts the bottom of the grid component 10 along at least part of its length. This contact provides rigidity and hence enables the trim to be made from very thin material.

Title: Variable pitch marine propeller
Inventor: BERNT JORGEN O
IPC: B63H3/02
Filed: 1985-11-25
Abstract: The pitch of a blade of a marine propeller can be varied by relative rotation between a propeller shaft 14 and an inner shaft 30 co-axial therewith. Under normal driving conditions, drive from a motor shaft 19 is transmitted via gears 15, 17 to the shaft 14 which transmits drive via a gear 42, gears 44, idler gear (or spinner) 46, and gears 55 to a gear (54) mounted on the shaft 30. To vary blade pitch a housing 50 can be rotated by a chain drive engaging a sprocket 60 thus rotating the axis of rotation of the gears 55 relative to that of the gears 44 and causing relative rotation of the shafts 14, 13 superimposed upon their driven rotation. Such relative rotation is transformed into pitch change by means of a worm 36, worm wheels 38 and helical gears 25A, 25B secured to the blades 22. <IMAGE>
