Patent GB-2023268-A (GB)
Title: Fluidized bed furnaces
IPC: B01J8/44
Filed: 1979-07-05
Abstract: A fluid-bed furnace has at least one combustion chamber housing a bed of incombustible particulate material to be fluidised when burning fuel fed thereto. Bed fluidisation is by forced release in the incombustible material of combustion promoting gas, normally air, from a plenum chamber (38) arrangement externally of the bed proper at a side or end thereof to save overall height. Furnace exhaust gas is returned to the bed for additional fluidising and heating purposes and release (53) within the bed of such returned exhaust gas is at a position higher than normal combustion promoting gas. Other features include an auxiliary burner within the combustion chamber to consume fine fuel material lifted from the bed in operation; insulation of at least the normal combustion promoting gas plenum chamber externally by incombustible bed material and/or internally by refractory lining; end tapering of bed traversing gas feed pipes to reduce expansion resistance; and a removable end plug in the latter pipes to ease cleaning thereof. <IMAGE>

Title: An automatic needle selection mechanism for a knitting machine
IPC: D04B15/78
Filed: 1979-10-09
Abstract: An automatic needle selection mechanism for a knitting machine comprises one electromagnet (14a-d) for each of a plurality of needle selectors (4a-d), and a movable mounting plate (13) for the electromagnets, arranged to face a selector bed (1) which is reciprocable in the direction of the selectors. The mounting plate with the electromagnets is moved in timed relation towards and away from the selector bed. Each electromagnet is brought adjacent to its corresponding selector when the selector is in a first position and the mounting plate is appro. The electromagnets are selectively energized when adjacent the selector bed and the mounting plate is then moved away from the bed. The selectors which correspond to the energized electromagnets are thus moved to a position where they are disengaged from the selector bed, and subsequent movement of the bed, and subsequent movement of the selector bed in the longitudinal direction of the selectors thereby actuates the needles of the remaining selectors in order to form a desired knitting pattern. <IMAGE>

Title: Indexing Mechanism
IPC: F16H19/00
Filed: 1980-09-12
Abstract: An indexing mechanism comprises a linearly reciprocated driving rack member (10) having localised teeth which mesh with a rotatable toothed wheel (13) coupled to the apparatus to be indexed. The teeth of the driving member (10) are localised in one, or in two opposed quadrants considered about the axis of elongation of the member. The driving member (10) is moved linearly and then rotated to bring the teeth out of mesh at the end of the driving stroke, this rotational movement being coupled via a yoke and slide (19, 20), carrying cam surfaces (22), to a locking member which is forced between the teeth of the toothed wheel at the instant that the driving member (10) disengages. The locking member (17) ensures precise stopping of the toothed wheel (13). It is withdrawn simultaneously with further rotation of the driving member (10) to bring the rack teeth back into mesh with the wheel (13) for a further indexing stroke. <IMAGE>
