Title: Tubing caliper
IPC: E21B47/09
Filed: 1961-06-07
Abstract: 917,208. Magnetic testing apparatus. CAMCO Inc. June 7, 1961 [June 23, 1960], No. 20516/61. Class 37. In an arrangement for gauging, or detecting flaws in, an elongated annular body of magnetic material, at least one flux sensing device, e.g. a Hall plate, is included in at least one of the air gaps between a magnet and the wall of the body to determine gap reluctance, and provide an indication of gap size. A magnet 611, Fig. 2, is mounted to be rotated by a battery-driven motor within the sonde, across the faces of Hall plates 8 arrayed on the inner face of a non- magnetic sonde 2c, and the pulses from the Hall plates when the sonde, which is provided with a pair of spaced nylon centralizing rings around its periphery, is lowered into a ferromagnetic tube are applied to a plurality of magnetic recording heads to provide a permanent record of the pulse amplitudes on a moving tape driven by a further motor housed within the sonde. An odd or even number of evenly spaced Hall plates may be used, and the two poles may be arranged to rotate in the same transverse plane or different planes, the magnet in the latter case having either staggered polepieces or being mounted at an angle to the spindle. The reluctance of one gap in the case of rotation in two planes may be to a considerable extent eliminated by the addition of a ferrous screen to the outside of the sonde around one of the planes of rotation and extending for some distance down the sonde away from the other plane. Details of the sectional assembly of the sonde are given, and reference is made to the inclusion of a screw-adjustable mechanical time-delay whereby to permit of lowering the sonde to a predetermined level before testing is commenced. The apparatus may comprise a rotating ring magnet to surround and caliper an outside tube diameter.

Title: Improvements relating to fuel-supply regulating means for internal combustion engines
IPC: F02D1/00
Filed: 1954-07-15
Abstract: 763,027. Regulating. DAIMLER-BENZ AKT.-GES. July 15, 1954 [July 25, 1953], No. 20700/54. Class 7 (6). [Also in Group XXVI] The regulating rod 1, Fig. 1, of a fuel injection pump is operated through a linkage 3, 8, extending substantially in a straight line and comprising a joint 21 movable about a fixed axis 4 located outside said line, by a device 11 responsive to engine output, such as a diaphragm responsive to intake pipe suction, and the fuel supply is corrected for variations in atmospheric pressure and/or temperature by movement of a further joint 7 in the linkage transversely of the direction of movement of the links 3, 8, the joint 7 being guided approximately on an arc of a circle about the axis 4 when the device 11 moves while the connecting means stays at rest. In Fig. 1 the link 3 is attached to a member 5 pivoted at 4 and provided with a slot 6 in which slides a pin 7 attached to the link 8, the pin 7 being carried by a lever 13 attached at one end by links 14, 15, 16 to a device responsive to atmospheric temperature and at the other end by links 17, 18 to a capsule 19 responsive to atmospheric pressure. In the full load position of the rod 1, the slot is in the position 6, Fig. 2, and increase of temperature causes movement of the rod 14 upwards which raises the pin 7 and, due to the inclination of the slot 6, causes movement of the rod 1 to the left to reduce the fuel supply. Similarly a decrease in atmospheric pressure causes expansion of capsule 19 and raising of the pin 7 to decrease the fuel supply. As the engine load decreases the device 11 moves the links 8, 3, to the right to decrease the fuel supply, the slot 6 moving to a less inclined position 6' so that movements of the pin 7 produce smaller corrective movements of the rod 1. In the zero supply position of the link 3, 8, the slot 6 is vertical as shown at 6" and the corrective devices have no effect. In a modification, Fig. 4, the capsule 19 is inserted in the link 20 connecting the thermometric device to the pin 7 so that the corrective devices act in series. In a further modification the pin 7 is carried by link 3 and the slot 6 is omitted, the pin 7 being connected by a link to the lever 5 which is also pivoted to the link 8.

Title: Improvements in or relating to self - orientating radio direction finders
Inventor: BYATT DENNIS
IPC: G01S3/42
Filed: 1954-07-19
Abstract: 758,983. Photo-electric pulse generators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 26, 1955 [July 19, 1954], No. 20932/54. Class 40 (3). [Also in Group XL (c)] A radio direction finder having a member which is automatically positioned in dependence on the incoming signal direction includes means for repeatedly producing a series of pulses, the number of pulses in each series being dependent on the position of said member relative to a fixed member, and means for determining the total number of pulses over so many repetitions together with means determining the total number of repetitions. If the pulse count is divided by the number of repetitions an average value of direction indication is provided comparatively free from errors caused by fluctuations and modulation of the signals. In the preferred embodiment an Adcock aerial system A is coupled to a goniometer GT the output of whose search coil is fed to the control grids of cathode-coupled valve s S1 and S2. A 300 c/s reference signal is fed in at P3 and applied to phase splitter valve P1 which has outputs feeding equal signals in antiphase to the suppressor grids of S1 and S2. The combined modulated outputs from these valves are further combined with a signal from omnidirectional aerial MO in transformer MC before application to receiver MF. The receiver output is fed to energize one winding of induction motor JT through amplifier MN; the other winding of the motor is fed from source P3. The motor is so coupled as to rotate shaft KT to bring the search coil of goniometer GT mounted on it into a null position and automatically maintain null conditions. Pointer RP on the shaft thus moves over its scale to give an indication of the bearing of the incoming signal. This indication may fluctuate considerably. According to the invention an arm LT is mounted on the lower end of shaft KT and is positioned by it. Mirror LM on the arm reflects light from a source NL to photo-cell NP when the latter is directly under it. The photo-cell is mounted on a disc QP driven at a constant speed by motor JB. The disc also carries a pole piece VP co-operating with an inductor VL to produce an electric impulse when it is in a reference position. The shaft KB driving the disc carries a phonic wheel WT co-operating with a pick-up coil WL to provide a train of pulses, each pulse being equivalent in the example given to 1 degree rotation of the shaft KB. The pulses are fed to gate circuit BE which passes each series of pulses received between the arrival of the reference impulse and the pulse from the photocell. Counter BF fed from the gate circuit determines and indicates the total number of pulses in these sets from a given starting time. A further counter CE counts the number of times the gate is open, i.e. the number of sets of pulses. Division of the number indicated by counter BF by that indicated by CE gives the average indication. A known form of computing device may be used to perform the division and directly display the answer.
