Abstract: 1516422 Measuring moisture content electrically MOLINS MACHINE CO Inc 19 Feb 1976 [30 May 1975] 06507/76 Heading G1N The moisture content of glue lines 27 in a freshly made web 26 of corrugated paperboard is monitored by an R.F. absorbtion detector. Web 26 is drawn by endless belt 32 across transmitting elements 22, 24 connected to an R.F. Hartley oscillator 12", Fig. 3 and spaced apart from one another and from the web by a distance equal to the width of a glue line 27. The R.F. field set up by the elements 22, 24 is amplitude modulated by the web 26 in accordance with the amount of energy absorbed thereby and the amplitude modulated signal A" is applied to envelope detector 16" including non linear element 44" and low pass filter 46". If the web 26 is moving slowly or is static the low frequency signal B" from the detector 16" may be applied to an ammeter to indicate the moisture content of the glue lines or used as a control signal. If the web 26 is moving quickly signal B" is applied via differentiator R4C3 to A.C. amplifier 58 and thence to peak to peak detector 54 including rectifier circuit 62 and R.C. circuit 64 the time constant of which is long with respect to signal B". Thus the signal at E is a D.C. signal the magnitude of which is proportional to the moisture variation between glue lines 27 and dry liner 30. After further amplification at 56 the signal is applied to an indicator or used as a control signal to heating elements 72, 74.

Abstract: 1462523 Pick-up arm assembly SONY CORP 13 Feb 1974 [17 Feb 1973] 6604/74 Heading G5R In an arrangement for preventing the occurrence of tracking distortion during playback of a gramophone record, the longitudinal centre line of the pick-up cartridge holder extends at an angle # to a line joining the cartridge stylus S to the point of support P of the pick-up arm; the arm is rotatably mounted on a spindle 6 at the position P at a distance CP from the centre C of a rotary member 7 which rotates in a cylindrical member 19 secured to the gramophone chassis and a detector system which provides an output to rotate member 7 is provided for ensuring that the prolongation of the line joining the stylus S to position P always passes through a point X in which condition the geometry of the arrangement ensures that the cartridge centre line is substantially always tangential to the groove at the position being scanned. A light-photocell detector arrangement 43, 44 disposed directly below the point X co-operates with a shutter member 29 which rotates with the pick-up arm spindle 6 and the output from the detector operates a motor which can drive the rotary member 7 via a belt 135 and frictionally coupled pulley 23 in either direction to maintain the required position. To prevent the arrangement responding to record eccentricity the detector is made insensible for positions of the shutter to each side of its mid-position in the detector. A pick-up arm lifter 11 is mounted on a shaft 12 which extends via an oil damper 82 to a tube 86 to which it is connected by a spring 85. The tube is connected to the plunger of a solenoid 83 mounted on the gramophone chassis which when energized moves the lifter downwards to allow the pick-up arm stylus to engage the record. At the end of record play the fast movement of the shutter illuminates the detector for a relatively long period detected by a time sense circuit to thereby generate an end of play signal which releases solenoid 83 to cause the pick-up arm to be raised. This movement of the arm is detected by a switch 84 which initiates return of the pick-up arm to its initial position. Means are also provided for automatically setting down the pick-up at the start of records of preselected diameter and for setting down and raising the pick-up from selected positions on the record so that a desired part only of the record is played.

Title: Control of nuclear power plants
IPC: G21D3/12
Filed: 1960-02-25
Abstract: 878,436. Nuclear power plant. SULZER FRERES S.A. Feb. 25, 1960 [March 31, 1959], No. 6685/60. Class 39(4). In a gas-cooled reactor of a power plant changes in the reactor load are effected without excessive changes in the gas temperature. As shown, the reactor 1 is supplied with carbon dioxide gas from compressors 2-5 through the heat exchangers 31-34, which produce steam for turbo-generators. If, with compressors 2-4 in operation, it is required to raise the load on 1, the compressor 5 is brought into circuit. The small, secondary valve 24 is opened and the compressor started. Initially, gas flows from the supply pipe 19 through 24 and the compressor. As the compressor speed rises the back flow is reduced and the main valve 14 is opened. Thus, as 24 is not closed during the first stages of the operation, the temperature of carbon dioxide is not raised by the compressor and the reactor is not subjected to a flow of high temperature gas when 14 is opened. In addition, the hot gas would be followed by very cool gas from the heat exchanger 34 and this is also prevented. Instead of changing the compressor speed, the flow may be controlled by adjustment of the compressor vanes.

A first major face (the lower face as shown) of a wafer 1 of monocrystalline silicon of a first conductivity-type is covered with an oxide layer having holes at the places where fieldeffect devices are to be produced, and through each of these holes an impurity is diffused into the wafer to form a region 4 of a second conductivity-type (Figs. 1 and 2, not shown); grooves 5 surrounding the regions where components are to be formed are etched on the first major face of the wafer which is then oxidized, forming an oxide layer 2 (Figs. 3 and 4, not shown) which is then covered with a thick deposit 6 of polycrystalline silicon. Material is removed from the second major face of the wafer so that the grooves 5 filled with polycrystalline silicon 6 appear on the surface (Figs. 5 and 6, not shown), and masking and diffusion are effected on this second face to produce regions 9 of the second conductivitytype which penetrate deeply enough to make contact with the ends of the previously-diffused regions 4 (Figs. 7 and 8, not shown). Further masking and diffusion on the second face produce regions 11 of the second conductivity type, each located directly above a region 4 and linking the associated pair of regions 9 (Figs. 9, 10 and 11, not shown), and each transistor is completed by the deposition of source, drain, and gate electrodes 12, 13, and 14 respectively.

Abstract: 374,130. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London. -(Assignees of Nyquist, H. ; Marion Avenue, Millburn, New Jersey, U.S.A.) March 5, 1931, No. 6846. Convention date, May 1, 1930. [Class 40 (v).] A regenerative amplifier for high or low frequencies comprises at least three, or a higher odd number of stages, and at least one interstage network coupling with series and shunt reactances, the former having resistances in shunt and the latter resistances in series therewith, the feedback path also including a reactance shunted by a resistance. The object is to secure stable operation where the feed-back ratio for a given range of frequencies is real and greater than unity, and the current fed back at one or more frequencies is in phase with the input current. The input coupling to the first amplifier 3 comprises resistances 4, 5, 6, the last being shunted by a condenser 7. The output of the last stage 24 is shunted by two resistances 26, 27 and the feed-back connection 28 is taken from the mid-point of these to a point between the input resistances 5, 6. The intervalve coupling comprises a low-pass filter 11 .. 16, a condenser 8, and resistances 17 .. 22, which, together with the condenser-shunts 10, 25, 31 prevent undesirable phase-shifts at the higher and lower frequencies. The output resistances 26, 27 and input resistances 5, 6, 7 form a balanced-bridge arrangement with the internal valve capacities to prevent variations in feedback due to changes in the load impedance. Owing to the presence of a certain amount of reaction in the circuits, the feed-back will vary with frequency both as regards magnitude and phase-angle. For regulation and supervision the feed-back ratio is measured by opening the circuit between the grid and the resistance 32 of the valve 24, and applying a voltage VI, Figs. 3 and 4, from an oscillator 35, Fig. 3, as measured by a meter 39 plugged in across a jack 38. Voltages V3, V2 are then measured from the jacks 36, 37, and the phase-angle # is determined from the vector diagram, Fig. 4. The feed-back ratio can then be calculated in terms of the angle # and the ratio of V2 to VI.
