Title: Measurement of high frequency electro-magnetic radiation
Inventor: HOOVER JOHN CLARKE
IPC: G01R29/08
Filed: 1962-11-30
Abstract: 998,779. Measuring high frequency electromagnetic radiation. SPERRY RAND CORPORATION. Nov. 29, 1963 [Nov. 30, 1962], No. 45338/62 Heading G1U. A device for use in the measurement of high frequency electromagnetic radiation includes a pair of parallel conducting surfaces 42, 29, separated by insulating plastic 41 and mounted on an insulating sheet 28, formed with at least one pair of similar slot aerials at right angles to one another (e.g. 26, 27), each slot aerial having a square law voltage detector, e.g. a thermistor, connected between conducting surfaces on each side of the slot. The conducting surfaces are divided by gaps so arranged that the detectors of each slot are connected in series. It is advantageous to have a further pair of slots (24, 25) cut in the surfaces, the dimensions of the slots being such that the two pairs respond tofrequencies just beyond opposite ends of the frequency spectrum which the device is required to accommodate. The longer, low frequency slots 26, 27 have conducting foils 43 attached behind them to shut out high frequencies from these slots, and the whole assembly is backed by a layer 45 of plastic loaded with conducting particles, this arrangement appearing reactive at low frequencies and therefore shunting the high frequency slots at these frequencies. The series arrangement of thermistors within the device is connected across a pair of terminals 39, 40 (Fig. 9) to act as one arm of a Wheatstone bridge, and the bridge is balanced in the absence of radiation. Any radiation falling on the device will produce changes in the thermistor resistances, and because of the right angle arrangement of the slots. and the fact that the thermistors are square low voltage responsive devices, the sum of these changes will be independent of the plane of polarisation of the incident radiation. The indicator 49 may therefore be calibrated to indicate the intensity of the radiation. The device and circuit arrangement may conveniently be assembled in a single casing and used as a portable instrument (Figs. 7 and 8, not shown). It is suggested that the thermistors may alternatively be connected in parallel.

Title: Process for preparing a fertilizer product
IPC: C05B7/00
Filed: 1965-10-27
Abstract: KNO3 is made by cooling a first aqueous solution consisting of H2O, (NH4)2HPO4 and KNO3 from an elevated temp. below 150 DEG C. to a temp. low enough to yield solid pure KNO3, e.g. 30-40 DEG  C.  The KNO3 is then separated from the remaining aqueous solution. The first aqueous solution can be formed by reacting KH2PO4, NH4NO3 and NH3 at 80-100 DEG  C. and controlling the proportions of the reactants so as to yield solid (NH4)2HPO4 which is then separated from the remaining first aqueous solution.  Alternatively the first aqueous solution can be formed by reacting a solution containing (NH4)2HPO4, KNO3, (NH4)2PO4, KH2PO4, NH4NO3, NH3 and H3PO4.  The remaining aqueous solution phase can be converted to a fertilizer by adjustment of the N-K-P ratio and by dilution.

Abstract: 1283868 Disc brakes; automatic adjusters BENDIX CORP 25 Sept 1970 [3 Oot 1969] 45743/70 Heading F2E A spot-type disc brake assembly 10 wherein a brake shoe 26 is applied by a piston 36 slidable in a chamber 34 of a housing 32 and a brake shoe 24 is applied by reaction via a caliper 12, incorporates an automatic adjuster mechanism 46 within the housing 32 which mechanism 46 comprises a nut 48 threaded on to a post portion 50 of an elongated member 52, the nut 48 being threadably movable along the post portion 50 to adjust for brake pad wear but the elongated member 52 having a surface 78 acted on by hydraulic pressure such that at pressures above a predetermined value the mechanism 46 is slidable in the chamber 34 to prevent adjusting action of the mechanism 46 at pressures above this value. This ensures that over adjustment of the mechanism 46 does not occur during a " panic stop." As shown, the piston 36 has a washer 58 which via an anti-friction bearing 62 acts to turn the nut 48 on the post portion 50 when the piston 36 has moved in actuation through a distance indicative of brake pad wear. During return movement of the piston 36 the threads of the nut 48 and the post portion 50, which threads have a helix angle of substantially 18-21 degrees, look to prevent backward movement of the nut 46 and a shoulder 64 on the piston 36 comes into abutment with the nut 46 to halt the piston 36. Hydraulic pressure is communicated to the surface 78 by a channel 80, but during normal application a spring 84 prevents movement of the elongated member 52. A mechanical actuator 92 is incorporated in the disc brake which actuator 92 comprises a handle 94 and a toggle 96 movable to cause movement of the member 52 and the piston 36.

Abstract: 1,016,561. Photo-electric control of photographic printing. GEVAERT PHOTO-PRODUCTEN N. V. Dec. 22, 1961 [Dec. 22, 1960], No. 46104/61. Heading G1A. [Also in Division G2] In a method of making photographic prints from transparent or opaque subjects at least one of the quantities of blue, green and red light incident upon the subject depends on the integrated transmittance or reflectance of the subject both for the corresponding colour and at least one other colour. Part of the light from a source 1 passing through a transparency 2 is deflected to photo-cells 5 sensitive to blue, green and red light respectively. The outputs of cells 5 is fed through logarithmic amplifiers 6 to a computer 7 which derives the quantity of light for each colour Ei according to the equation: - where Di,j,k are the integrated transmittances of the transparency to blue, green and red light, a i  is a constant, b i  the correction co-efficient and c i  d i  are cross-correction co-efficients. The outputs of computer 7 are fed through antilogarithmic amplifiers 8 to colour control means. In a particular embodiment, c i  = di = (1-b i )/2, the result of which is the application of full correction to average (grey) transparencies and reduced correction to transparencies exhibiting colour subject failure. The invention is applicable to additive or subtractive printing systems using simultaneous or sequential exposures.

Spool 18 is mounted on a shaft 17 which entrains a flange 30. Inertia member 32 is pivoted on the flange and is influenced by colibration spring 33. Relative movement of flange and member 32 forces a tooth on the latter into engagement with internal teeth 40 on a surrounding cup 38. A clutch spring 41 rotated by the cup moves a lever to bring the lock bar into path of the teeth 52 of the spool flange 22.  The blocking arrangement 56 comprises a yoke 57 pivoted on an extension 64 of the flange and biased by a spring 68. During initial pay-out of the belt, frictional drag of extensions 69 against the hub 39 pivots the yoke anticlockwise, maintaining it under the inertia member 32. Meanwhile, extension 65 winds nut 75 outwards along threaded boss 74. Upon slight retraction of the belt the yoke is swung over-centre to the position shown clear of the member 32. During any subsequent protraction of the belt in an emergency the member is free to initiate locking.

Abstract: 1412781 Data processing systems SCHLUMBERGER INLAND SERVICES Inc 12 Oct 1972 [13 Oct 1971] 47031/72 Heading G4A Well logging measurements are processed by machine to combine the measurements to produce an output parameter, e.g. hydrocarbon density, to adjust the value of at least one of the measurements to a new value and compute a new output parameter, and to compare the original and new values of the output parameter to indicate its reliability. In the process described, logging measurements are used to calculate "derived" measurements of shale content V sh , effective porosity # e , water saturation S xo  of mud-invaded zone surrounding the bore and the measured values of γ-ray bulk density # D  and neutron porosity # N  are corrected for the calculated shale content (48), Fig. 3 (not shown). The corrected values # D  and # N  are tested (49) to determine whether or not they indicate a hydrocarbon bearing zone. If a hydrocarbon bearing zone is indicated and the resistivity data is consistent with S xo  (90), a routine RODET is entered, Fig. 5 (not shown), to compute the hydrocarbon density RHOH, this being followed by a routine ROVAR (Fig. 4, not shown) which modifies the values of # D , # N , V sh , S xo  by predetermined amounts, derives corresponding new corrected values for # D , # N  and computes a new value RHOH<SP>1</SP> for RHOH. Fianally a reliability factor VAR is calculated proportional to the modulus of RHOHKHOH<SP>1</SP>. If the VAR indicates reliability (53) RHOH is printed out together with the depth level, V sh , # #  and VAR, and when three or more consecutive depth levels with reliable values of RHOH have been found, a running average ROM is maintained over the last three levels for use as a minimum value ROMIN in other parts of the program. If step (49) indicates a non- hydrocarbon bearing level RHOH is set to the density for oil and ROVAR is run to test the reliability of the assumption. If the resistivity measurements (90) are inconsistent with the calculations of step (48), V sh  is modified by increments until # D ## N  (49) or V sh  becomes substantially zero in which case the data is considered unreliable, RHOH is set to ROM and a move is made to the next level. An initial pass through the logging data may be made, Fig. 6 (not shown), to identify sand and shale formations and compute reliable values of RHOH from reliable data derived as deep as possible in each formation, a boundary between adjacent intervals having potentially different values of RHOH being declared when a shale formation thick enough to act as a barrier against hydrocarbons is detected. A plurality of reliable values are averaged to from a preselected value of RHOH for use in the process described above.
