Patent GB-821138-A (GB)
Abstract: 821,138. Automatic ship stabilization systems. MUIRHEAD & CO. Ltd. Dec. 11, 1956 [Dec. 22, 1955], No. 36815/55. Class 38 (4). [Also in Group XXXIII] A ship is stabilized to its mean angle of list by stabilizers which are automatically controlled in accordance with a signal dependent on instantaneous angle of list modified by a signal dependent on mean angle of list, both signals being derived from a vertical-keeping reference. In Fig. 1, movement of an arm 4 of a gyro vertical 1 upon rolling of a ship positions a contact 18 relative to contacts 12 and 13 of a follow-up switch so that a two-phase motor 17 is operated to move a follow-up member 11, carrying contacts 12 and 13, towards the off position. Slow operation of member 11 ensures that it takes up a position corresponding to list of the ship and an A.C. signal dependent on list is developed by winding 23 of an inductive device 20 driven by member 11. This signal is applied to a second rotor winding of a transmitter selsyn 7, the rotor of which is displaced by arm 4 so that the A.C. output signal from windings 19 of inductive device 7 is representative of roll angle about the list position. This signal is applied to a differential receiver selsyn 39 to which signals representative of derivatives of roll are also applied from a transmitter 36. Arm 37 of selsyn 39 controls stabilizers so that roll is damped out but list remains. In a modification (not shown), instead of employing a follow-up switch, motor 17 is controlled by the output signal from selsyn 7.

Title: Method of inhibiting differential wall sticking in the rotary drilling of hydrocarbon wells
Inventor: MOSES EDWARD L
IPC: C09K8/03
Filed: 1983-06-29
Abstract: A method of inhibiting the occurrence of differential wall sticking in the rotary drilling of hydrocarbon wells is provided. The yield point of the drilling fluid is measured and if necessary increased in a known manner to a minimum value computed from the weight of the drilling fluid so that solid, substantially spherical glass beads having a specific gravity between 2.4 and 2.65, a diameter between 9.84 and 187 mils, and a hardness of 5.5 Mohs placed therein will not settle, and 10 to 50 ppg of the glass beads are added to a quantity of the drilling fluid. A slug of the glass beads/drilling fluid mixture is then spotted in the well bore adjacent a previously identified zone of possible sticking, so that a substantial number of the glass beads may be deposited in the filter cake lining the wall bore adjacent the zone of possible sticking. The presence of the glass beads inhibits the formation of a seal between a drill string, down hole tool or casing and the filter cake, which seal is necessary for the occurrence of differential wall sticking. In an alternative method, the glass beads/drilling fluid mixture is pumped into the well bore without identifying zones of possible sticking.
Patent GB-832834-A (GB)
Abstract: 832,834. Fare-collecting and registering apparatus. UNIVERSAL CONTROLS Inc. Aug. 20, 1957, No. 26258/57. Class 106 (3). [Also in Group XXXVII] A multiple coin fare-collecting and registering apparatus for handling coins of different diameters comprises an inclined shoot down which the coins slide, an aperture in said shoot, a rearwardly yieldable detector button within said aperture, the button being contacted and moved backwards by a coin as the latter crosses the aperture, and means responsive to such backward motion of the button to close a switch in the circuit of a unidirectional electric motor and thereby start the motor. Coins are fed into a space 12 on the shoot 10 from a coin-receiving hopper not shown, the space 12 being enclosed by a transparent plate 11. A coin entering the space 12 strikes a guide rail 13 and from there rolls down a curved and inclined rail 14, 15 under a bar B and into contact with a guide surface 17 which directs it into one of a number of peripheral cut-outs 21 in a rotor 18. The rotor 18 is carried by a shaft 19 and overlies the shoot 10. The shoot 10 comprises a movable part or door 23 fastened to the main part of the shoot by strips 24 pivoted at 24a; the door 23 is normally held flush with the surface of the shoot but can be swung backwards to release a coin lodged under the bar B. The detector button 25 is mounted on an arm 26 pivoted at 26a to a bracket on the rear side of the door 23. An extension fixed to the upper end of the arm 26 carries a weight 29 at its upper end which tends to keep the button 25 in a position where it projects through an aperture in the door 23 (see Fig. 2), which registers with one of the cut-outs 21 in the rotor 18 and which is of a diameter smaller than that of the smallest coin to be received by the apparatus. When a coin is directed into the cut-out by the guide surface 17 it depresses the button 25 which causes a permanent magnet 30 fastened to the lower end of the arm 26 to actuate a switch S (see Group XXXVII), which, through a relay, starts an electric motor connected through gearing to the shaft 19, thus causing the rotor 18 to turn in an anti-clockwise direction, Fig. 1, and carry the coin C to a position where it is contacted by a gauging finger 22 which determines, by means not shown, the denomination of the coin and relays this information to the registering apparatus. When the coin C and the adjacent radial arm 21a of the rotor 18 have moved from over the button 25, the button is again free to move outwards under the influence of the weight 29, thus switching off the motor and stopping further rotation of the rotor 18.
