Abstract: The casing for a filter comprises at least two body portions defining a chamber for the filter means. The body portions are relatively movable between a closed position in which fluid cannot escape between them, and an open position in which fluid can escape between them. An increase in pressure in the chamber tends to urge the body portions to their open position, but there is resilient means which resists that and only permits the portions to part when the pressure in the chamber reaches a predetermined value.

Abstract: A brake comprises a rotor which is permitted to float axially and a friction pad which is carried by a support. The support is movable towards and away from a braking surface of the rotor and is urged to a datum position under the action of a return force. A spring or other resilient device is provided which is yieldable when the return force exceeds a predetermined amount to permit movement of the friction member beyond its datum position to compensate for float of the rotor surface, the spring urging the friction pad towards the datum position when the return force is reduced below the predetermined amount.

Abstract: In a fluent fuel burner using a flame anchor plate, secondary air from a plenum leaves the plenum through a restricted passage so that the secondary air is at high velocity and correspondingly low pressure and this low pressure is used to suck the flame to the rim of the anchor plate. Two dual fuel burners are described in which a gaseous fuel introduction means has an enlarged end portion which extends from within the air plenum into a combustion space, the said portion having slots in it to allow primary air to enter the said portion to serve as primary air for combustion, and which has associated with it a flame anchor plate. The plenum has a wall on the combustion side with a hole in it. In one embodiment, the anchor plate overlies the rim of the hole so that a narrow annular passage defined between the plate and the wall directs the secondary air in a radial blast.

Abstract: In an opening roof assembly for an opening in the roof of a vehicle the roof covering is tightened or released by a handle mechanism which is coupled to a flap through a pair of rods. The rods are moved towards and away from each other in response to rotation of the handle mechanism. The free ends of the rods work in inclined slots in downwardly depending flanges on the flap so that relative movement between the rods causes the flap to move angularly with respect to a front cross-member of the roof assembly on which it is pivotally mounted. Rotation of the handle mechanism in a direction to tighten the covering is accompanied by the flap being drawn down into close sealing engagement with the roof around the front of the opening.

Abstract: A filter suitable for filtering gases comprising a resilient foamed synthetic plastics filter element having a perforate support extending thereacross, and a peripheral resilient foamed synthetic plastics sealing frame, the edges of the element being located in a channel of the frame and secured therein by marginal portions of the perforate support extending into the frame.

Abstract: The invention is a multi-purpose exercise bench that can be readily converted to any one of eight different uses quickly and without the use of tools.

Abstract: A rear view mirror for a motor vehicle in which a mirror head is mounted for angular movement about two axes at right angles to each other and is adjustable about these axes by rotation of a single control shaft. Adjustment of the head about one axis is effected by rotation of an eccentric element by the shaft, and adjustment about the other axis is effected by linear movement produced by rotation of a second element such as a scroll cam or screw thread. A lost motion device is arranged between the shaft and at least one of the elements so that a degree of adjustment of the mirror head about one axis can be effected without alteration to the angular setting of the head with respect to the other axis. The lost motion device may be arranged between the two elements or between an additional fine-adjust device and both the elements.

Abstract: A disc brake caliper consists of a body member including a cylinder portion, and a bridge member attached to the body member by two bolts. The body and bridge members of the caliper abut one another at two pairs of parting faces lying in a common plane, aligned bolt holes for the two bolts being formed in the parting faces. The cylinder portion of the body member extends axially beyond the parting plane so that a recessed portion of the bridge member overlies but is spaced from the cylinder portion to form an air pocket which is adequately vented. The two parting faces on the body member can be machined simultaneously by means of two broaching tools which clear the cylinder portion.

Abstract: A rotary mechanical seal assembly for a shaft comprises a freely floating ring of flexible material which has inner and outer axially directed lips to bear against the surfaces of the shaft and housing, at least one of these lips being normally out of contact with its associated surface so that no wear takes place. The seal is brought into action by the application of pressure either applied from an outside source or created by leakage past an adjacent upstream face-type seal for which the seal of the invention forms an emergency back-up. There may be a detector to sense the leakage. There could be two such lip seals facing one another.

Abstract: A sliding caliper disc brake comprises a caliper member adapted to straddle a minor portion of the periphery of a rotatable disc, a carrier member for fixing to a vehicle, guide means guiding the caliper member for sliding relative to the carrier member, and an actuator for directly urging a friction pad onto one side of the disc to cause the caliper member to slide relative to the carrier member to apply by reaction an opposite friction pad to the other side of the disc. The guide means includes a pair of pins connected to one of the members and slidable within respective openings in receiving means connected to the other of the two members. In order to locate the caliper member against undue movement about either of the two pins, each pin is a snug sliding fit within the respective opening. Furthermore, at least one of the pins or receiving means is connected to the associated member by a resilient element adapted to flex so as to limit forces transmitted between the pins and receiving means.
