Patent GB-2112650-A (GB)
Title: Stand, e.g. for golf bags
Inventor: HUSSEY DOUGLAS
IPC: A63B55/57
Filed: 1982-08-26
Abstract: A folding stand is provided, primarily a support stand for a golf bag. The stand includes a facility 56 for de-actuating the automatic operation of the actuating rods 44, 45 which cause the stand support legs 38, 39 to move to the open position to support the golf bag. This means that after use the stand can be put in a position where the support legs will not automatically fly out when the stand is set down on the ground. This makes it easier to stow the stand with the bag upright in a locker or against the wall of a room. <IMAGE>

Title: Percussive tool
Inventor: TUPITSYN KONSTANTIN KONSTANTIN
IPC: B25D9/06
Filed: 1982-09-04
Abstract: A percussive tool comprises a percussion mechanism (1) and a pressure pulser (2). The percussion mechanism (1) has a hollow housing (3) with a piston hammer (5) arranged thereinside to form two chambers (6, 7) of variable volume. The pressure pulser (2) has a hollow housing (9) and a fluid displacer (10) defining inside the housing (9) a working chamber (11) adapted to alternately communicate with a source of gaseous fluid and the interior of the percussion mechanism (1).

Patent GB-2111705-A (GB)
Title: Printing plates
Inventor: DICKINSON PETER
IPC: G03F7/09
Filed: 1982-11-02
Abstract: A presensitised lithographic printing plate has a base, especially a grained metallic base, bearing a light sensitive layer of diazo resin. Over this is applied an abrasion- resistant oleophilic layer based on non-light sensitive polymer. This upper layer incorporates a substance that will absorb light in the wavenumber range of the photochemical absorption band of the diazo resin. This absorbtion avoids a tendency for dark areas to become solid black when exposed under a high intensity source. By using a diazonium salt as the light absorber, it becomes possible through the further addition of an indicator dye to obtain an immediate visible image on exposure.

Filed: 1983-03-18
Abstract: A smoker's pipe comprises a bowl portion (16) having a tobacco- receiving cavity (18) below which is formed a transverse, tapering socket (20). A passageway (22) interconnects the cavity (18) with the socket (20). A tapering end extent (8) of a stem portion (2) is a friction push- fit into said socket (20) whereby the bowl portion (16) can be rotated about said end extent (8). The stem portion (2) includes a bore (4) communicating directly with, and forming an extension of, the passageway (22), a primary reservoir (12) in the lower regions of the bowl portion (16) communicating with the bore (12) and the passageway (22) but not being in the direct path between said bore (2) and passageway (22), thereby keeping to a minimum the internal surface area of the pipe between the cavity (18) and the bore (4), said reservoir (12) storing unwanted liquid in the pipe. Rotation of the bowl portion (16) relative to the stem portion (2) seals off the cavity (18) from the reservoir (12) and bore (4). <IMAGE>
