Title: Flame effect with fan blown flexible material
Inventor: WILLIAMS DARRELL LEE
IPC: F24C7/00
Filed: 2008-08-04
Abstract: A flame effect has a light source (e.g. single lamp or bulb 2) at the bottom of the fire body, positioned below a horizontally orientated electric fan or blower 4 on an inclined panel 5 which is at an angle to a vertical orientated back panel 6, in front of which is a single piece or sheet of flexible reflective material 7 suspended like a sail that ripples or billows in the blown air. The material can be reflective on one side - the front. The flexible material 7 is loosely suspended at the top from three spaced locations (X,Y,Z fig 3) so that it sags. The illuminated material is viewed through a semi-transparent, diffracting or translucent screen (8, fig 2). A coloured filter; varying light intensities and blower speed; weighting of the flexible material or securing points along its lower edge; a simulated fire bed; a movement generator other than a fan; a low wattage bulb; a second piece of flexible material; or a wire or rib focal point may enhance the effect. The effect may be part of an electric fire or hot water radiator.

Title: Handle-free metal detector with visual indication of detection
Inventor: PEARSON ROBERT ANDREW
IPC: G01V3/15
Filed: 2009-07-01
Abstract: A metal detector for underwater use by divers who are more often horizontal when at the seabed and not vertical, which holds itself in place by means of straps 2 and 4 which go over the back of the hand and wrist and indicates the presence of metal objects by means of LED light strips 8. A wire ribbon 5 connects the scanning disc 1, which houses both the transmitting and receiving coil and control unit 3. The detector uses the most popular VLF (very low frequency) technology. The detector can be switched on or off underwater by the power control button 6 on the control unit 3.

Title: Improvements in and relating to hydraulic piston valves
IPC: F15B13/02
Filed: 1943-06-30
Abstract: 568,927. Valves. TOWLER, J. M., and TOWLER, F. H. June 30, 1943, No. 10577. [Class 135] A control valve of the piston type can be connected in series with a number of similar valves, the last in series being of the type such as in Specification 557,340, which unloads a pump when pressure liquid is not directed to an associated cylinder, the arrangement being such that the valves can be operated independently to control supply of liquid from the pump to one of a number of cylinders. As shown in the Figure, the valve member reciprocates in a cylinder bore surrounded by six annular chambers of which chamber 1 communicates with the next valve in the series, chamber 2 with the pump delivery via a passage 18, chamber 3 with exhaust, chambers 4 and. 6 with the hydraulic cylinder under control, chamber 5 through a passage fitted with a non-return valve 14 with the pump delivery, while the chambers at the two ends of the bore communicate with exhaust. The valve member has three lands A, B, C, with bevelled control edges. The land A has two series of radial ports 16 communicating with an axial passage 15. The valve member has five positions and when in either of the two end positions communication between the chambers 1, 2 is interrupted and pressure is supplied to one end of the hydraulic cylinder, while the other end is connected to exhaust. In the mid - position, communication is established between the chambers 1, 2 and the chambers, 4 and 6 are isolated from both pressure and exhaust. In two intermediate positions, communication is maintained between the chambers 1, 2 and one of the chambers 4 or 6 is connected to exhaust while pressure is maintained in the other chamber via the non- return valve. A spring-loading may be fitted, urging the valve to return to one of the intermediate positions when the operating handle is released after the valve has been moved to one of its extreme positions. A spring detent may be fitted to hold the valve in the intermediate positions. In a modification, four lands cooperate with ports in a cylindrical liner, exhaust from one end of the hydraulic liner being effected through an axial passage extending to one end of the valve member. Both forms may be modified to control a single-acting cylinder by omitting one of the lands and one of the annular chambers. In a modification permitting more than one valve being effective at the same time, the check valves 14 are isolated from the passage 18 leading to the chamber 2 and are connected to a manifold supplied to the pump.
