Title: Locking device for a dosing arrangement of an anaesthetic vaporizer
Inventor: FALB WOLFGANG
IPC: A61M16/18
Filed: 1992-02-19
Abstract: A locking device (10, 11) for a hand wheel (2) of a dosing arrangement (3, fig 1, not shown) of an anaesthetic vaporizer (1), having an unlocking device (6) that releases the locking device for allowing actuation of the dosing arrangement (3), is improved in that the unlocking device (6) is blocked in operating states which are not suitable for the operation of the anaesthetic vaporizer (1). The improvement is attained in that the locking device has a final control element (20), (24, 29, Figs 4, 5, not shown) which covers a regulating distance which is dependent upon a parameter which affects the operating state of the anaesthetic vaporizer (1) and the regulating distance of which is transmitted to a blocking arrangement (13) which, in the case of values of the parameter which are not suitable for the operation of the anaesthetic vaporizer (1), blocks the unlocking device (6). The unlocking device (6) is blocked by a pin (16) movable by a bellows (20) engaging a cut-out (15) in a block (14) on the unlocking device (6). The bellows (20) is subject to the internal temperature of the vaporiser. The bellows may be replaced by a bimetal (24, fig 4, not shown). The parameter may be the internal pressure of the vaporiser, the pin (16) then being movable by a pressure box (29, fig 5, not shown). Other vaporiser parameters include its angle of inclination, its level of anaesthetic liquid, and its inlet gas composition. <IMAGE>

Title: Dispensing device
Inventor: SMITH TREVOR
IPC: B65D83/16
Filed: 1992-06-29
Abstract: The device dispenses a dose of material, such as a perfume or deodorant, automatically on closing a door. The device comprises a holder 1 adapted to be fixed to a surface, such as a door, and an arm 4, 5 extending therefrom, the arm being hinged at a point 6 along its length. The holder is able to accommodate a storage container and a dosage chamber with associated valving. This combination may take the form of either an aerosol or a container with a small pump (Fig. 5). In operation the hinged portion is folded back A onto the holder such that this portion is pressed towards the valves or container during door closure (as a result of relative movement between, for example, a door and its jamb) to push the aerosol or pump to activate delivery of the dose. Ribs 7 on the arm act to bias the two parts of the arm apart. <IMAGE>

Title: Vehicle propelling member and assembly
Inventor: NICHOLS BRUCE MACKENZIE
IPC: B60F3/00
Filed: 1992-08-25
Abstract: A vehicle propelling assembly to propel a vehicle in a given direction comprises a pair of propelling members (19a, 19b) each having a body portion (20a, 20b) which rotates about a rotation axis extending substantially at right angles to the direction of travel of the vehicle. Body portions (20a, 20b) extend along a plane which is substantially in alignment with the rotation axis and include a curved ground or fluid engageable portion (22a, 22b). The vehicle propelling members (19a, 19b) can be mounted to ends of an axle assembly (15) which can be secured to a vehicle through a coupling assembly comprising a ball and socket assembly (25) and connecting struts (30, 31), which are pivotally connected at one end to axle assembly (15) and at the other end to a connecting member (32) which itself is pivotally mounted for movement about a vertical axis. The coupling arrangement accommodates the various forces acting on the axle assembly upon rotation of the propelling members. The assembly can be used as a substitute for vehicle land wheels and provides increased adhesion to a ground surface. The assembly can also be used in marine applications and will also allow a vehicle to move over soft ground surfaces such as snow, mud or soft sand.

Title: Tilt device
Inventor: MCCANN JOHN JOSEPH
IPC: B65G65/23
Filed: 1993-12-21
Abstract: A tilting device or stooper for beer barrels comprises a vertical support (36), a base (38), an actuating member (40) pivotally connected to the upper end of the support (36), and a coil tension spring (48) connected at its upper end (50) to the actuating member (40) and at its lower end by means of a hook (46) to a rear end of the barrel. The other end of the barrel is supported upon a scotch (24). As the weight of the barrel decreases during discharge of beer, the rear end of the barrel will be lifted under the influence of the spring (48) to tilt the barrel on the scotch. The device thus provides automatic stooping of 8 beer barrel in a controlled progressive manner avoiding undue disturbance of the finings. Preferably the scotch or chock has a cradle, a pivot point and a hook for connecting to the barrel. <IMAGE>

Title: Temperature-responsive slot ventilator
Inventor: STONEY ARTHUR
IPC: F24F11/76
Filed: 1994-08-18
Abstract: A ventilator, secured to the exterior side of a ventilator slot extending between the interior and exterior of a building, has a housing with an inlet and an outlet and a bowed wall (21) therebetween. A normally straight baffle strip 26' is attached to the centre of the wall (21) and there are non-aligned apertures (25), (28) in the wall and baffle respectively. When the pressure differential between the inlet and outlet is low and the air temperature is warm, the baffle 26' is well-spaced from the wall, but when the air temperature becomes very cold, bimetallic strips 40' cause the baffle 26' to bow towards the wall to close the flow path through the apertures. The bimetallic strips may be progressively acting or snap type. The baffle 26' is also pressure responsive, as in the prior art Fig. 4 (not shown), responding to increased pressure differential to bow towards the wall and progressively restrict the apertures. <IMAGE>

Title: Vehicle anti-theft system
Inventor: SMITH JOHN BARRIE
IPC: B60R25/08
Filed: 1994-10-13
Abstract: An actuator comprises a cutoff valve 45 inserted in the hydraulic supply line to two diagonally opposite wheels 1 and 4. After master cylinder 36 operation those wheels can be isolated with the brakes applied to prevent theft whilst the vehicle is unattended. A pressure-relief valve 49 reduces the pressure at the wheels so as to prevent the wheel cylinder seals being damaged. Microswitch 48 operated together with valve 45 cuts off the fuel supply and disables the ignition circuit. In the embodiment of figure 1, parking brake pressure is applied by an actuator having a plunger moving in a cylinder 7. Operation of the plunger may simultaneously actuate a fuel cut-off valve 22. The actuator is operated by a key 47, 13 or by entry of a predetermined number via a keypad or a card, and may be mounted in the vehicle transmission tunnel by fastenings arranged to release the actuator into the tunnel in the event of tampering. <IMAGE>

Title: Production of heat from solid carbonaceous fuels having relatively high ash     contents
Inventor: SHARPE JOHN ERNEST ELSOM
Filed: 1995-06-01
Abstract: A process for producing heat energy from solid carbonaceous fuels having relatively high ash contents comprises subjecting the fuel to pyrolysis and gasification in a bed 2 of the fuel in a combustion chamber 1. The fuel is reacted with primary air together with steam and/or water vapour and/or recycled exhaust gas. The gas produced from the bed is subjected to secondary combustion. The fuel bed is unsupported by a grate, and the primary air is introduced into the fuel bed by means of one or more apertured tubes 4 projecting into and/or through the bed. The ash resulting from the pyrolysis and gasification is continually removed from the bottom of the combustion chamber in a particulate and unclinkered state.
