Title: Well logging tool scale selection circuit
IPC: G06F7/62
Filed: 1972-09-04
Abstract: 1362898 Scale selection TEXACO DEVELOPMENT CORP 4 Sept 1972 41005/72 Heading G4H The division factor of a divider comprising a chain of bi-stables is set remotely by changing the count in a counter, the output of which enables one of a set of gates connected one to each bi-stable. The system may be used for altering the output count of an oil well radioactivity logging tool. As shown, pulses proportional to radiation are generated in " logging tool electronics " 10 and fed via line 11 to bistables 12-17 which act as divide by two circuits. The output of each bi-stable is also connected to the input of an AND gate 44-49 and the outputs of these gates are connected via OR gate 52 to " logging tool electronics ". One gate at a time can be enabled and the output pulses are either logged in 10 or passed to the surface via cable 30. The gate that is enabled is determined by the state of the binary counter comprising bi-stables 55, 56, 57 which are connected to the gates 44-49 so that six of the eight possible slots of the counter enable gates, the other two being used for reference, A.C. pulses are transmitted from the surface to step the counter. These pulses pass low-pass filter 36 and resonant circuit 36 and are converted to D.C. pulses in differential amplifier 40 and trigger 41.

Filed: 1966-09-21
Abstract: 1,155,375. Particle detectors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 21 Sept., 1966 [24 Sept., 1965], No. 42145/66. Heading H1K. A detector for discriminating between particles of different masses comprises superposed junctions, the upper one having a thin space charge region when reverse biased so that it produces an output proportional to dE/dx and the lower one a thick space charge region in which the remaining energy of the particles is absorbed so that its output is proportional to E. The upper junction is formed in a layer epitaxially deposited on a wafer containing the other junction or at the interface of the layer and wafer. In one embodiment phosphorus or. antimony is diffused into the face of a high resistivity P-type silicon wafer 500 Á thick to form the lower junction. High resistivity N- type silicon is then epitaxially deposited from the vapour phase over the diffused face to a thickness of 2-3 Á and a PN junction formed in it. Part of the diffused N layer is masked during deposition or subsequently re-exposed by etching and contacts attached to layers of silver paste or vapour deposited gold applied to it and to the P regions of the two junction elements. In an alternative embodiment the epitaxially deposited material is P-type and forms the upper junction with the diffused N- type layer. The product of the outputs of the two junctions is proportional to E.dE/dx and hence to mz<SP>2</SP>. If the charge z on the particles is known, particles of different masses can therefore be identified.

IPC: H03G3/02
Filed: 1970-09-07
Abstract: 1,262,848. Automatic gain control in pulse radar. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 7 Sept., 1970 [10 Sept., 1969], No. 42770/70. Headings H3T and H4D. A circuit for time-dependent amplification control in radar receivers is characterized in that the control-voltage is derived from a cascade of monostable trigger circuits adjustable in pulse duration and output amplitude, whose separate output voltages are applied in common to a stepwise adjustable amplification stage. The initiating pulse is applied to the base of a transistor amplifier T1, from the collector circuit of which is triggered the first, e1 of a cascaded train of monostable trigger circuits e1-e6, each triggered from the output of the preceding one. The time-constants of the individual trigger circuits are determined by capacitors C1-C6, in conjuction either with adjustable resistors R1-R6 or alternatively adjustable resistors R7-R12, the changeover being effected by switches UK1-UK6 under control of magnetic relay RE1. The outputs from the monostable trigger circuits e1-e6 are combined in a resistive network comprising adjustable resistors R19-R24 and diodes Gr1, Gr3, Gr5, Gr7, Gr9, Gr11 which allows of the individual output levels being pre-set. Alternatively, the resistive network comprising adjustable resistors R25- R30 and diodes Gr2, Gr4, Gr6, Gr8, Gr10, Gr12 may be brought into operation by means of switches operated by magnetic relay RE2. The combined outputs are applied to an emitterfollower T2, the output level from which may be set by means of alternative adjustable potentiometers P1-P3, brought into circuit by means of switching relays RE3, RE4. The time-constant of the emitter-follower is increased by means of capacitor C so as to smooth the variations in gain control potential. The gain control voltage may be arranged to operate only in one sector of the panoramic image by switching on and off or controlling its amplitude in accordance with the north or alternatively the ship's direction.

Title: Fuel/air mixing and carburettors therefor
IPC: F02M7/28
Filed: 1972-09-15
Abstract: 1396524 Sensing air-fuel ratio ENERGY TRANSMISSION CORP 15 Sept 1972 42961/72 Heading G1B [Also in Division F1] In a carburetter having improved fuel atomization (see Division F1) a continuous sample of exhaust gas from a manifold is taken to a valve mechanism which modulates bleed air flow in response to air-fuel ratio deviations as measured by the combustible ingredients remaining in the exhaust gas. The exhaust gas is divided into equal amounts and admitted into chambers 150, 152, Fig.8, to pass through catalyst beds 126, 128 and thence via chambers 156 and passages 162, 164 to exhaust vent tube 110. The bleed air enters via passage 166 and upwardly through tubes 168 thereafter passing downwardly via annuli 170 in which it may be heated from the catalyst chambers 126, 128. The perforated cap 140 allows some bleed air to pass with the exhaust gas through the right hand chamber 128. The thermal sensing air from both tubes 168 passes downwardly through passages 172, 174 into respective left and right hand temperature sensing chambers 176, 178 and thereafter is vented via passages 182, 184 into a vent air passage 180. Part of the bleed air entering via tube 100 passes via a divider passage 194 and orifices 196, 212 into sub-chambers 200, 216 and thence flows downwardly through passages 202, 218 to a bleed air accumulation passage 206 communicating with passages 106 leading to the mixing chamber of the carburetter. Each sub chamber 200, 215 has a valve 210, 224 controlled by a thermally responsive element 208, 224 whereby some bleed air can be vented to passage 108. Valve 210 opens with temperature increase and valve 224 closes with temperature increase. Operation. If the mixture becomes lower the temperature in the left hand sensing chamber 176 becomes higher and the temperature in the right hand sensing chamber 178 lowers causing valves 210, 224 to open to vent bleed air from the chambers 200, 216 thereby reducing the bleed air flow to the mixing chamber 42, Fig.1, to richen the mixture. If the mixture richens the converse sequence takes place to weaken the mixture. The opposite opening and closing operation of valves 210, 224 tends to cancel the affect of ambient temperature changes.
