Title: Window closure device
Inventor: WHITWORTH DAVID GEORGE
IPC: E05B65/00
Filed: 1985-11-22
Abstract: A self locking closure device (10) for an opening light (15) of a window comprises a cylindrical base part (11) attached to the sub-frame (14) of the opening light (15) and having a bore (16) in which is rotatingly received the cylindrical body (15) of a handle part (12). A handle (20) and a latch (21) angularly displaced therefrom, extend laterally of the head (19) of the handle part (12) and a plunger (26) extends along an axial bore (22) in the handle part (12). A locking pin (36) slides in laterally extending axially aligned bores (34, 35) in the base part (11) and the body (15) and is biassed by a spring (37) into contact with the plunger 26. With the opening light (15) closed the plunger (26) must be depressed against a spring (31) to cause the locking pin (36) to move inwardly out of lateral bore (35) in the base part (11) and allow rotation of the handle part (12), thereby releasing the latch (21) from a latch plate (32) attached to the window main frame (33). When the opening light (15) is closed and the handle part (12) returned to the securing position the spring (31) pushes the plunger (26) so that an enlarge part (27) thereof pushes the locking pin (36) into the lateral bore (35) of the base part (11) to secure the closure device (10) in the securing position. <IMAGE>

Title: Compacting a moulding mixture by a pressurised gas wave
Inventor: BECKETT COLIN PHILIP
IPC: B22C15/00
Filed: 1987-11-25
Abstract: The pressure of the impaction gas is reduced from its maximum delivery pressure at or immediately prior to the point of impaction of the gas on the mixture. The apparatus includes a moulding box (24) containing the moulding material around a pattern (20) on a pattern plate (18), and a pressurised gas impaction unit (14) provided with a gas reservoir (30), quick release valves (34) for releasing the gas wave, and a discharge frame (32) through which the gas is released into the box (24), the frame (32) having exhaust vents (36) which effect the reduction of the gas pressure from its maximum. The gas compacted mixture, is then additionally squeezed from its rear face, against a squeeze head (16). The mood produced by this method and apparatus is evenly compacted and has no holes therethrough. The moulding box may be laterally transported between a box filling location (A) and a position (B) at which it is raised by a piston (26b), firstly against the frame (32) for the gas compaction, and then against the squeeze plate (16). Alternatively, each of the filling (12), impacting (14), and squeeze means (16) may be transversely displaced into alignment with the mould box, or vice versa. <IMAGE>

Title: Panel for resiliently gripping bricks for use in forming a brick facade
Inventor: BAUER ROBERT WILLIAM
IPC: E04F13/08
Filed: 1987-12-23
Abstract: A structure and method is disclosed for facilitating the construction of a brick facade. A panel (12) is provide made of bonded vacuum formed polystyrene and extruded polystyrene foam. The outer portion (22) is specially configured to secure bricks in place by a friction fit until mortar is laid. The rear surface of the bricks (14) are secured by adhesive to the surface of the outer portion (22) of the panel. Channel bars (18) separate the bricks (14) in a vertical direction while other spacing means are used to locate the bricks (14) in the horizontal direction the proper distance from one another. The mortar is then laid in place by hand to create the effect of bricks laid by a mason. Because of the materials used and the configuration, the panel can be cut at the work site to accommodate variations in the structure being erected. The cutting operation can be accomplished by a commerical cutting knife, the panel nailed in place, and bricks (14) laid within the panel by an unskilled construction worker.
