Title: Improvements in or relating to rotary percussive drills
Inventor: SIMPSON FRANK F
IPC: B25D17/08
Filed: 1983-05-31
Abstract: A rotary percussive drill has means for positively disconnecting the rotary drive (7) and also means for positively disconnecting the drive (6,10) for the percussion mechanism (16). The disconnections may be controlled by separate operating members (38,41) or by a common member (90).

Title: Spread spectrum receiver
Inventor: WELLS JOHN HAROLD CHARLES
IPC: H04B1/69
Filed: 1983-07-22
Abstract: In order to obtain code synchronisation more rapidly than is possible by using a spread spectrum receiver comprising only a Costas loop having a narrow band filter, a code synchronisation detector (20) is provided. The detector (20) operates by analysing the output spectrum derived from a wideband part of the receiver, for example the output of the IF stage. Once code synchronisation has been detected then a clean data signal can be derived from the Costas loop (16). The analysis is done in one embodiment (Figure 3) by comparing the outputs of a high pass filter (24) and a low pass filter (26) which have responses related to the known synchronlsed and unsynchronised conditions. In another embodiment (Figure 5-not shown) the analysis is done by comparing the energy in substantially the entire spectrum with that in a portion of the spectrum. In a further embodiment (Figure 6-not shown) the analysis is done by comparing the energy in the upper and lower sidebands of the RF or IF spectrum with that at the centre of the spectrum. (Figure 3). <IMAGE>

Title: A method of further processing strand type material wound with the help of a flyer
Inventor: HENRICH WERNER
IPC: B65H57/18
Filed: 1984-06-01
Abstract: When a wire (or the like) is wound on to a spool or the like, using a flyer, the wire acquires a twist which is frequently undesirable during further processing, (e.g. stranding rope). It is now proposed that the wire (58) should be drawn in an axial direction from the spool (52) or a wire bundle in such a manner that a twist produced during winding is eliminated. This may be achieved by drawing the wire from the outer turns of the wire bundle in the direction opposite to the incoming direction or by drawing it from the inner turns of the bundle in the same direction as the incoming direction. In the latter case this could be achieved (as shown) by drawing it off in direction (59) i.e. the direction opposite incoming direction (3) and then guiding it through the spool (52) in a direction (171) in line with incoming direction (3). The spool may have a conical flange, with a guiding ring, to facilitate withdrawal. <IMAGE>

IPC: A62B18/04
Filed: 1986-09-15
Abstract: The invention relates to breathing apparatus comprising a two-piece helmet 11 with a see-through panel 19 in its forward regions. Two flexible resilient seals 20,26 extend from the see-through panel 19 into pressure contact with the wearer's face to define two isolated volumes V1 and V2.
