Title: Method of and apparatus for additive layer manufacture
Inventor: WILLIAM THOMAS RICHARDSON
IPC: G01N21/956
Filed: 2017-02-08
Abstract: A method and apparatus for additive layer manufacture, e.g. with an electron beam, wherein to monitor layer quality, structured light defining a fringe pattern is projected onto each deposited layer before S2 and/or after S10 melting of material in that layer. The fringe pattern on each layer is imaged S3, S11 from a perspective different from that of the projection so as to reveal disturbance of the pattern by topographical features of the layer (Fig 1b) and recognize defects in the layer before melting S4, S5, S7 or in a cross-sectional layer of the article formed after melting S12, S13, S15. If defects are detected layer deposition is correctively influenced, e.g. by vibrating or otherwise smoothing the layer S6, S8 or by introducing energy, e.g. by separate optics, e.g. to partially melt the cross-sectional layer. Further material may be added, removed, or replaced. A fringe pattern algorithm, e.g. phase stepping procedures, FFA, DPD, or wavelet transform fringe analysis may be used to demodulate fringe patterns with subsequent unwrapping algorithms used.

Title: Mitigated dynamic underbalance
Inventor: KEVIN SCOTT HARIVE
IPC: E21B43/119
Filed: 2015-02-13
Abstract: A perforating gun assembly for use in a wellbore includes a carrier body and a charge holder disposed within the carrier body. One or more shaped charges are supported by the carrier body and are operably coupled to a detonator for igniting a highly explosive material within the each of the shaped charges. At least one solid propellant tablet is also disposed within the carrier body and is operably coupled to the detonator to ignite and burn immediately after detonation of the shaped charges. The solid propellant tablet burns or is consumed in such a manner to effectively mitigate or control the dynamic underbalance created by the free volume within the carrier body. Burning of the solid propellant tablet may increase the pressure within the carrier body to a level lower than a hydrostatic pressure around the carrier body in the wellbore such that a dynamic underbalance is maintained.

Title: A threshold detector circuit for lossless switching
Inventor: RAYMOND JOHN PETO
IPC: H03K17/13
Filed: 2017-07-25
Abstract: A threshold detector circuit is suitable for lossless switching of a transistor. The circuit senses a voltage across the transistor and is operative such that when the voltage across the transistor exceeds a user defined HIGH threshold, the threshold detector circuit remains in a quiescent state with a low input impedance to a signal to the detector circuit. When the voltage across the transistor (collector-emitter or drain-source) is less than a user defined LOW threshold, the threshold detector circuit switches to an active state, so that the transistor is switched on thereby creating a low input impedance to a signal to the detector circuit. The continual isolation of the detector circuit from the transistor ensures that there is minimal noise passing to/from the transistor. The threshold detector circuit may include a switch control circuit connected across input terminals of a motor. The threshold detector circuit may include a soft start circuit.
