Title: Improvements in coal and wood burning stoves
Inventor: BABBAGE THOMAS ARTHUR
IPC: F23L1/00
Filed: 1984-01-10
Abstract: The invention provides a stove for burning a charge of fuel by primary air directed either above or underneath through the fire bed so that wood or coal may both be burned efficiently a grate is defined by fixed bars 18, 19 attached to a frame 13 and to an array of movable fire-bars 12, 20 the movable bars 12 having a length greater than their width when viewed endwise and being rotatable between a vertical attitude in which they permit upward passage of air and downward passage of ash through said support and a horizontal attitude in which they permit build up of a layer of ash at the base of the fire bed. The movable fire-bar 20 at one extremity of the array has a surface semi-circular profile that maintains a constant spacing from the adjoining fixed bar 19. The fire bed is unlikely to jam with particles of clinker of fuel. Means including an air diversion flap causes the primary air to flow above or below the grate depending upon the attitude of the fire-bars 12. <IMAGE>

Title: Optical viewing apparatus
Inventor: SILLITTO HILLARY GIL
IPC: G02B23/10
Filed: 1989-08-15
Abstract: The apparatus permits an external target to be viewed along a sight-line 11 by a sensing device and for the projection of a beam of laser radiation 12 towards the target. The apparatus includes a first partially- reflecting member 10 partially transparent to radiation at a wavelength to which the sensing device is sensitive and inclined at an angle to the sight-line 11. The member 10 has a viewing area through which the target may be viewed and a laser output area through which the laser beam passes. A second partially- reflecting member 13 receives radiation from the first partially-reflecting member (10). A retro-reflector 14 is provided for receiving laser radiation reflected from the second partially-reflecting member 13 and for deflecting such radiation by way of the second partially-reflecting member 13 onto the viewing area of the first partially- reflecting member 10 for reflection into the field of view of the sensing device on the sight-line 11. This radiation accurately represents the direction in which the transmitted laser radiation is being projected regardless of alignment errors of the laser source or of the optics. Fixed polariser 17 and adjustable polariser 18 act as intensity control means. <IMAGE>

IPC: H02J9/08
Filed: 1989-11-09
Abstract: A load L is normally supplied from a main source P via a rectifier Rec 1, overcurrent breaker NFB2 and inverter IV. Failure of the main source P is sensed by an undervoltage relay RY1 causing start-up of an engine-generator E-G providing an emergency supply via a rectifier Rec2, diode D1 and overcurrent breaker NFB1. A battery B is charged via a current limiter LC from whichever of the main source P and generator E-G is in operation. If during normal supply from source P, a malfunction in overcurrent breaker NFB2 or rectifier Rec1 occurs, the inverter IV is energised from the battery B. An undervoltage relay RY2 starts the generator E-G if the battery voltage falls below a predetermined level. <IMAGE>
