Title: Security fastening
IPC: E05C5/02
Filed: 1981-08-14
Abstract: A security fastening for locking windows comprises a shaft 19 carrying a cross-pin 20 which engages a keep-plate 2. The shaft 19 is borne for limited rotation between a dividing wall 16 of the body 6 and a button 14 which latter is borne slidably but non- rotatably in the body 6. A spring 27 biases the shaft and button axially towards the illustrated inoperative position and is also stressed torsionally so as to bias the shaft in one sense of rotation. Normally, rotation of the shaft is prevented by the fit of the cross-pin 20 in a recess 15 of the body 6. However, when the button 14 and shaft 19 are pressed in, the pin 20 passes out of the recess 15 and through an aperture 32 into a recess 33 of the keep plate 2 where it rotates behind an abutment surface 34 under the torsional bias of the spring 27. To unlock the device a hollow key is engaged with a driving dog 22 at the opposite end of the shaft 19 to rotate the pin 20 back into alignment with the aperture 32 and recess 15, and the shaft and button can then spring back to the inoperative position. <IMAGE>

Title: Indicator instruments
Inventor: WRIGHT GRAHAM BOOTH
IPC: G01D13/14
Filed: 1983-03-07
Abstract: A depth meter or other indicator instrument has a pointer (10) or a series of sequentially energisable light emitting elements that is rotatable around a circular scale (2) calibrated in metres, upon change in depth. At five metres intervals there are small display regions (11 to 20) that are energised to produce numbers '0' to '45' representative of the depths associated with respective points of the scale. The number in each display region (11 to 20) remains constant until the pointer (10) moves past the region (16) showing the number '25', when the opposite display region (11) changes the number displayed from '0' to '50'. As depth increases further, the instrument changes successive display regions (12, 13 and so on) opposite the pointer (10) to read '55', '60' and so on. At depths greater than 50 metres the point (10) is rotated through more than 360 DEG  until it passes the region (16) representing 75 metres when the opposite region (11) changes from '50' to '00' (representing 100 metres). Further increase in depth rotates the pointer (10) but does not change the numbers displayed by the regions (11 to 20). <IMAGE>
