Title: Method of determining the location of a deep-well casing by magnetic field sensing
Inventor: KUCKES ARTHUR F
IPC: G01V3/26
Filed: 1982-02-05
Abstract: In a method of locating a deep well casing (12) at substantial distances below the earth's surface, and for directing the drilling of a second, relief, well (22) to intersect the first well (10) at substantial distances below the earth's surface a low frequency alternating electric current flow is produced in the casing (12) of the well to be detected by means of current injected into the earth surrounding the first well e.g. by electrodes (36, 38). The current flow in the casing produces a magnetic field which is detectable by a sensitive magnetic field sensor (26) suspended in the relief hole (22) and spaced a substantial distance from the current source. The magnetic field sensor detects the magnitude and apparent direction of the alternating field, and this measurement is combined with a concurrent measurement of the earth's magnetic field to determine the direction and distance of the casing (12) from the relief well (22). This information is then used to direct the continued drilling of the relief well, with periodic measurements being made to provide directional control of the drilling so that the first well (10) is intersected at the desired depth below the earth's surface. <IMAGE>

Title: Electrostatic copying apparatus
IPC: B65H1/04
Filed: 1979-12-12
Abstract: An electrostatic copying apparatus in which an original to be copied is scanned and exposed to light by relative movement of an optical system and an original-support means having a transparent plate on which the original is placed. Paper feed rollers (54) are rotated in response to the movement of the original support means or the optical system to thereby supply a copying paper sheet. A drive mechanism, which is adapted to reciprocate the original support means (4) or the optical system, has a driven wheel (470) and an idle wheel (486) rotatably disposed in spaced- apart relation to each other and a winding power transmission system (494) wound about these wheels and drivingly connected to one of the original-support means and said optical system. A synchronizing wheel (484) is rotatably disposed adjacent to, and coaxially with, the driven wheel (470) or the said idle wheel (486) of the drive mechanism. A protusion, such as a pin (402) is fixed to the winding power transmission system (494). A plurality of engaging portions, such as teeth (405) capable of cooperating with the engaging protrusion (402) are formed on a peripheral edge portion of the synchronizing wheel (484). The paper feed rollers (54) are fixed to a support shaft (436) mounted rotatably and drivingly connected to the synchronizing wheel (484), whereby when the drive mechanism is operated to move the winding power transmission system, the protrusion (402) engages one of said plurality of engaging portions (405) to rotate the synchronizing wheel (484) and thus rotate the paper feed rollers (54). <IMAGE>

Title: Device for the introduction of bulk material into a pneumatic conveyor line
Inventor: ESSMANN WOLFGANG
IPC: B65G53/12
Filed: 1983-08-09
Abstract: A pressure tank 3 and conveyor line 1 or-in the case of two pressure tanks-the two pressure tanks are connected to a differential pressure gauge and the shut-off device 14 is controllable in dependence upon the differential pressure gauge 27. In this way a particular differential pressure can be preset which, as long as the setting is unchanged, remains constant and which is solely determinative for the opening of the shut-off device of the pressure tank, so that independently of the extent of the conveying pressure in the conveyor line a constant pressure difference between the initial pressure and the conveying pressure can be maintained. <IMAGE>

Title: Pulsed regulation of current flow in coil circuit
Inventor: BRAUNGER JOACHIM
IPC: H02M3/156
Filed: 1983-09-07
Abstract: A switch (12) and a measuring resistor (13) are disposed in the current circuit of a coil (10), which is bridged by a freewheel element (11). A signal indicative of the voltage drop across the resistor (13) is compared in a comparator (14) with a freely selectable target value and the switch (12) is opened on attainment of the target value. The switch (12) is closed again after passing through a hysteresis of the coil current. A delay element (15) and a hysteresis switching stage (16) are arranged between the comparator (14) and the switch (12). The circuit is particularly suitable for current regulation in an electro- magnetic valve or coil ignition system. A timing circuit (17) prevents transient disturbance feedback when the switch (12) is closed. <IMAGE>

Patent GB-2201508-A (GB)
Title: Optical encoder
Inventor: ADAMS GRAHAM LEONARD
IPC: G01D5/347
Filed: 1984-02-29
Abstract: Rotation of an actuating ring 33 having a multi-lobed internal cam surface 34, such as by movement of a member whose movement is to be sensed, causes movement of a plunger 8 having a central web with an aperture 12 therein. In dependence on the position of the aperture 12 light can be transmitted from an optical fibre (13) via a lens (14) to a reflector element (11) and back down the optical fibre, or prevented from being so transmitted, thus encoding movement of the member as an optical signal. More than one aperture in the plunger web may be employed, for example, to increase the count resolution. The reflector element may be replaced by a return optical fibre which bypasses the plunger through a bore in the body member (1). Instead of using optical fibres, electrical conductors may be used and light generated adjacent the plunger on one side thereof by means of a light emitting diode, and transmission through the plunger aperture determined by a photodetector on the opposite side thereof. The optics in the shutter area are completely sealed from the environment by diaphragms (24) and the resulting cavity filled with silicone oil, thus enabling the encoder to operate in dirty or pressurised environments. <IMAGE>

Title: Severing sheets from a web
Inventor: GILMORE THOMAS GEORGE
IPC: B65H35/10
Filed: 1984-03-03
Abstract: When a set of paper sheets, arranged so that their ends over- or under-lap, are laminated to a continuous film it is not possible subsequently to sever individual laminated sheets from the resulting web with a conventional blade. Accordingly, one or more cuts are made in the film lamination only, these cuts being parallel to the longitudinal axis of web 10 and in the area if overlap, e.g. using rotary discs 28 near one edge of the web; the weakened web is then severed by pairs of rollers, 30,36 applying tension. This arrangement is particularly appropriate in the production of laminated book jackets. <IMAGE>

[Also in Group XVI] An apparatus for continuously winding a web on reels supported by rotatable arms is characterized by a stationary knife arranged at that side of a reel in winding position which is remote from a shaft carrying the arms, by a movable knife mounted in a tiltable frame for movement past the other side of the reel in winding position into cutting position, both knives extending laterally of the web, and by at least one guide roller for deflecting a cut web around an empty reel. As shown, a pair of winding spindles such as 13 are carried in arms 6 rotatable about a shaft 14, such that a completed roll may be moved to discharging position while an empty spindle is brought into winding position. In the position shown, winding is about to commence on the spindle 13; web is drawn on to the completed roll 12 between the spindle 13 and a presser roller 4, between knives 3 and 8, around guide rollers 10, and around a guide roller 15. A slide 2 is movable manually, electrically or hydraulically on a frame 1 towards and away from the shaft 14 to permit unobstructed rotation of the arms 6. The slide carries the roller 4 and a stationary knife 3, while a tiltable frame 7 carrying the rollers 10 and knife 8 is pivotally mounted on the frame 1 for rocking towards and away from the shaft 14. The knife 8, pivotally mounted on the frame 7, is rocked manually, electrically or hydraulically towards the knife 3 to cut the web transversely and to initiate winding on the spindle 13, the cut end of the web being guided around the spindle 13 by an air blast from a pipe 9.
