Title: Suction cleaning device
IPC: A47L9/16
Filed: 1979-11-08
Abstract: A hand-held suction cleaning device has a suction pipe (7) leading to a cyclone separator (2) with an annular separator chamber (3) into which pipe (7) feeds tangentially. The chamber (3) exhausts to atmosphere through a central exhaust pipe (15) and an upper exhaust chamber (19). Pistol-grip handle (1) has trigger control member (14) which operates air valve (13) controlling the air flow from inlet connection (12), which can be coupled to a compressed air supply, to nozzle (9) through pipe (10). Nozzle (9) is formed in the upper wall of pipe (7) adjacent the inlet end of the latter, and it produces an air jet which discharges into pipe (7) to produce an air flow therealong to separator chamber (3) and a resultant suction at the inlet end of pipe (7). Solids picked up by this suction are transported in the air stream along pipe (7) and separate out in chamber (3) from which they fall by gravity through funnel (4) into detachable container (5). <IMAGE>

Title: Apparatus for drawing perspective views
IPC: B43L13/14
Filed: 1981-02-23
Abstract: An apparatus for drawing one, two or three-point perspective views of objects on a picture plane (P) from a plan and/or two elevations comprises a representation mechanism for defining a representation of the object from the plan (A) and/or elevations, and a perspective view (A%). The representation is defined by defining for each point of the object its location in a plane parallel to the plan (A) using the perpendicular distances (d,r) from each point to the picture plane and a reference plane (R) perpendicular to the picture plane and its location on a line perpendicular to the plan (A) using the perpendicular distance (h) from each point to a horizon plane perpendicular to the picture plane and the reference plane (R). The perspective mechanism finds the horizontal location of the point using the distances d and r, and the vertical location by using the distances d and h and a fixed vanishing point. For drawing three-point perspectives the representation mechanism includes a rotation mechanism to rotate each point of the object before defining the representation. <IMAGE>

Title: Mounting arrangement for a stator vane of a gas turbine engine
IPC: F01D9/04
Filed: 1981-05-30
Abstract: A shallow mounting arrangement for a vane of a gas turbine engine in which the vane (18) has a foot (21) which is pulled against the inner surface of a casing (22) by set screws (27, 28).
