Title: Encoding and transmission system for mud pulse telemetry of tool face angle data
Inventor: ROESLER RICHARD FREDERICK
IPC: E21B47/18
Filed: 1985-08-06
Abstract: Orthogonal indicia of orientation of a drilling tool 22 at the end of a drill string 18 within a borehole 12 are measured by a pair of sensors at intervals of a first frequency. Pressure pulses indicative of the tool face angle are generated in the mud flow passing along the drill string 18 by means of a mud flow valve in response to each measurement, and the pressure pulses are sensed at the surface in the vicinity of the well head 28 so that the tool face angle data can be obtained and used by the drilling operator. When the drilling tool 22 requires rapid reorientation following the addition of a section of drill pipe to the drill string 18, the reduction in the pressure of the mud flow due to the interruption of the mud flow necessitated by such addition is sensed by a mud pressure sensor. The sensor in turn provides a transmission rate selector signal which changes the interval of tool face angle measurement from the first frequency to a second, higher frequency, with the result that a more rapid updating of tool face angle is possible for reorientating the drilling tool 22 following addition of a drill pipe section. <IMAGE>

Title: Machine for making paper booklets
Inventor: JONES STANLEY GERNARD
IPC: B26D1/60
Filed: 1987-12-09
Abstract: In a machine for making paper booklets from a multiplicity of paper strips on bobbins that are converged into a continuously advancing strand a reciprocating cutting station (25) defined by leading and trailing plates (27, 28) performs the operations of firstly clamping the strand while the station (25) moves with the strand and secondly of cutting off booklet lengths of paper by means of a knife (156). Cut booklets are ejected into a discharge chute (32) by ejection means (200) including an ejector bar (211) terminating a thrust plate (214). According to the invention the ejection means (200) is separated from the cutting station (25) and is fixedly located opposite to the chute (32). Connection between the cutting station (25) and the ejection means (200) is established by a common rotating hexagonal shaft (76) which is operably connected to clamping and cutting mechanisms of the station (25) and which carries a pair of cams (207, 208) that actuate the ejector (211) through a parallelogram linkage. By this means the motion of the ejector (211) can be gradual rather than abrupt, the machine is easier to set up, and the ejector thrust plate (214) can span substantially the full width of chute (32) so that the likelihood of cut booklets becoming misplaced is reduced.

Title: Grinding machine control system
Inventor: PRATT JEFFREY
IPC: B24B49/00
Filed: 1989-09-27
Abstract: A system for controlling the vertical movement of a grinding wheel of a surface grinding machine stores a vertical datum position set at a pre-selectable distance above a workpiece. The system automatically selects a desired stop position for the wheel which is a pre-set distance (typically .2 inch) above the datum position. The grinding wheel is then lowered rapidly towards the datum position and a stop signal generated at the desired stop position. Because of inertia of the wheel, the latter continues moving until it reaches its actual stop position. Overshoot of the desired stop position is monitored by the control system which then makes a compensatory adjustment of the desired stop position. Typically, the inertial movement is added to the datum position with a further clearance safety factor of typically .003 inch. In subsequent grinding operations the wheel is lowered rapidly to the new desired stop position and is subsequently lowered at a slower grinding feed rate. The control system monitors the inertial movement of the wheel at each grinding operation and readjusts the desired stop position accordingly. <IMAGE>
