Title: A radiation measuring and comparing device
IPC: G01J1/16
Filed: 1960-12-22
Abstract: 930,649. Photo-electric measurement of radiation. NORTH AMERICAN AVIATION Inc. Dec. 22, 1960 [Jan. 29, 1960], No. 44044/60. Class 40 (3). Apparatus in which radiation from two sources is compared comprises optical means for forming an image of one source in a plane containing the other, means for forming an image of each in a second plane in which these two images are spaced either side of radiation absorbing means which alternately interrupt at least a portion of each, and means for detecting the variation of intensity resulting from the interruption and for changing the intensity of one of the sources. As shown the radiation intensity modulator comprises a plate 20 containing an aperture 28 having two parallel sides across a portion of which aperture is moved in the direction of the parallel sides a vane 26, driven with sinusoidal motion by a moving coil vibrator 36. The vane and its motion, together with the aperture 28, define an upper and a lower aperture whose areas vary sinusoidally with time in opposite phase. In a pyrometer light from a source 10 whose temperature is to be determined is imaged by a lens 12 in a plane containing the filament 14 of a standard source 16, the filament and image being projected by a second lens 18 such that the upper aperture is filled by an image of the filament 14 and the lower by an image of the source 10. The radiation emergent from the apertures is incident upon a detector 34 whose alternating voltage output is dependent in phase and magnitude on the relative intensities of the images at the apertures. This voltage and a reference phase (being the signal energizing the vibrator 36) are supplied to a phase-sensitive rectifier 39 whose direct voltage output controls a transistor or thermionic impedance device 40 in the current supply line to the standard source 16 so as to match its temperature to that of the source 10, the temperature of the source 10 being indicated by an ammeter 42. For manual operation, the control device 40 is by-passed by a switch 44 and a rheostat 45 is adjusted to give a zero centre null on an indicator 46 coupled to the phase-sensitive rectifier 39. An alternative modulator in which graded density filters are moved over two apertures is described, Fig. 6 (not shown), and in either modulator cam drive may be employed instead of a moving-coil vibrator. A two-phase motor, Fig. 4 (not shown), actuating a variable resistor in the supply to the standard source 16 may be used instead of the phase-sensitive rectifier.

Abstract: 1321299 Steam distillation; deodorization of edible oils CHEMETRON CORP 21 Sept 1970 [17 July 1970] 44917/70 Heading BIB [Also in Division C5] An edible oil, e.g. soyabean oil, is submitted to steam distillation in tray 10 by directing steam, supplied through pipe 40, substantially horizontally into the oil through holes 34 in distributor 30 wherein the holes extend over a substantial vertical section of the distributor. The oil rises within cylinder 20, sputters against plate 50 and is directed downwards by lip 54. The oil circulates back into cylinder 20 through opening 25. The space between the holes should be equal to at least five times the diameter of the holes. The steam discharge velocity is approximately sonic. The tray 10, which has a sloping bottom 14, is mounted inside a vacuum shell 16, and ordinarily there it at least one heating tray above it, and at least one cooling tray beneath it. After the oil is deflected by lip 54, much of the steam carrying the volatilized fractions (including tocopherols and sterols) disengages from the oil, and is deflected by deflector 60 against the upper surface of plate 50. The vapour passes beneath the lower edge of baffle 74 and then over rim 11 between spacers 66 to shell 16, and thence to a condenser. Mist and droplets which collect on deflector 60 and baffle 74 return by gravity to the main body of oil within tray 10. Treated oil is discharged through valve 80. Animal fats, whale and fish oils may similarly be deodorized.

Title: D.c. to d.c. voltage regulator
IPC: H02M3/156
Filed: 1969-09-11
Abstract: 1285601 Automatic voltage control PHILIPS ELECTROLOGICA GmbH 11 Sept 1969 [9 Oct 1968] 44923/69 Heading G3R [Also in Division H3] A D.C. to D.C. voltage regulator comprises a series switching transistor T1 controlled by an impulse generating circuit formed from two NAND gates G1, G2 which operate as inverters interconnected by timing circuit capacitors C8, C9, the arrangement being such that impulses are generated to switch the transistor T1 on and off when the output voltage Ua is below a predetermined value, which switching continues until the output voltage exceeds another predetermined value whereat the gates G1, G2 operate to hold the transistor T1 switched off. The lengths of the on and off periods of the transistor T1 are respectively determined by the timing circuits C9, R19 and C8, R20, whilst the predetermined values of output voltage correspond to the off and on conditions of a transistor T3 which is responsive to the output voltage via a circuit comprising members R13, R14, R15 and which is switched on for a period following the connection of the regulator to the power supply when a capacitor C11 charges through a circuit comprising members D14, R15, T3 and R18. During this period the "on" condition of transistor T3 causes the gates G1, G2 to switch off a transistor T2 and hence the transistor T1 controlled thereby. When the capacitor C11 is charged, transistor T3 switches off to allow repeated switching of transistors T1, T2 until the output voltage reaches a value at which the transistor T3 is again switched on and transistors T1, T2 are switched off. With a steady input voltage Ue and load, the transistor T1 settles down to regular on and off switching corresponding to the predetermined values previously mentioned. The "on" periods of transistor T1 are of equal duration since transistor T3 cannot be switched on whilst transistor T1 is on. After each switching-on impulse generated by gates G1, G2 both the transistor T1 and the impulse generating circuit are switched off until the output voltage falls below the predetermined value to permit the generation of another switching-on impulse. Decrease of the input voltage or increase of the load reduces the output voltage sufficiently to permit the generation of a series of switching impulses to restore operation to the regular on and off condition. The value of regulated voltage may be raised by altering the switching limits of the transistor T3, which operation is effected by applying an earth to the input of a gate G3 connected via another gate G4 and members D9, R11, R12, to the base of transistor T3. Members R10, C5 smooth the changeover from one regulated value to the other. The gates G1...G4 comprise arrangements of transistors, diodes and resistors. Figures 2 and 6 (not shown). If the output voltage exceeds a predetermined value a Zener diode ZD1 conducts to fire a thyristor TR1 which short circuits the input voltage to blow a fuse. Transistor T3 is provided with a resistor-diode circuit R17, D10 which effects temperature stabilization, Fig. 5 (not shown).

Abstract: 1,078,509. Sliding clasp fasteners. SCOVILL MANUFACTURING CO. Oct. 22, 1965, No. 44954/65. Heading E2S. A method of producing a gap in interengaged coil type sliding clasp fastener stringers includes pulling the stringer tapes 12, 14 apart at the desired location of the gap without separating the interengaged coils 16, 18 in order to expose the interengaged parts of the coils, and cutting the coils between the spread-apart adjacent edges of the tapes without cutting the tapes for a distance corresponding to the desired length of gap. As shown, apparatus for carrying out the method, comprises a bladeshaped punch 28 carried by a top pad 26 which is slidable over a fastener tape support 24 and the downward movement of which pulls apart the tapes. A vertically movable cutting anvil 30, loaded by a relatively strong spring (50) Figs. 7 and 8 (not shown) supports the coils 16, 18 to be cut, and a scrap pad 32 is loaded by relatively light springs (36) for limited vertical movement within the anvil 30. In operation downward movement of the punch 28 against the springs 36 from the position shown depresses and severs the lower sides of the coils 16, 18; continued movement of the punch moves the anvil 30 and pad 32 downwardly in unison so that they grip and push the severed coils away from stitches 20, 22 on the tapes 12, 14. Subsequent return movement of the punch 28 and pad 32 raises the severed coils to the initial position of the anvil where they are displaced by longitudinal movement of the stringers as the latter are moved to the next gap location.

[Also in Division F2] A rotary hydrostatic bearing has at least one of the bearing members provided with a series of spaced shallow recesses therein connected by throttling restrictors to a source of high-pressure hydraulic fluid; and has internal and external circumferential weirs disposed adjacent the inner and outer edges respectively of the bearing surfaces, the weirs retaining sufficient fluid to seal the edges of the co-operating bearing members. In an embodiment, a nuclear reactor of the steam-generating heavy-water-moderated type, has a containment enclosure with a shielding roof 10 formed with a circular aperture 11 which is closed by a rotatable disc-shaped cover section 14 and is rotatably supported by a fluid bearing 13. The cover section 14 has an eccentric circular aperture 16 closed by a rotatable cover 17 on which a re-fuelling machine 15 is mounted. The machine 15 extends through a sealed eccentric aperture in the cover 17, to a reactor standpipe deck (not shown) within the shielded enclosure below the cover 10, for co-operation with selected standpipes. The cover section 14 can thus be rotated about the bearing 13 so as to locate the re-fuelling machine over a particular section of the standpipe deck, fine adjustments being made by rotating the cover 17. The bearing 13 comprises a number of bronze pads 26, Figs. 4 and 5, resting on resilient blocks 27 which are on a bed-plate 25 and are restricted in a radially-outward direction by link-plates 33. Each pad 26 has four recesses 40 therein which are supplied with pressurized fluid via restrictors 45. Outer and inner weirs 84, 88 are provided and serve as seals to prevent the escape of gas from the containment and through the bearing 13. The cover 14 also has an aperture 60 closed by a non-rotatable circular cover 61. When the machine 15 is located, the pressurized fluid is cut-off so as to lock the covers 14, 17 and a lowpressure pump comes into operation to maintain sufficient pressure in the weirs 84, 88 to seal the containment.
