Title: Improvements in or relating to methods of measuring temperatures
IPC: G01J5/06
Filed: 1961-04-21
Abstract: 918,564. Temperature measurement.  PHILIPS ELECTRICAL INDUSTRIES Ltd. April 21, 1961 [April 25, 1960], No. 14545/61. Class 40 (3). The invention relates to apparatus for the measurement of temperature and is particularly useful in the low-temperature range below 20‹ K. The apparatus comprises a source 10 of uncharged particles, such as neutrons, directing particles into the medium 11 whose temperature is to be measured, a detector 15 for measuring the energy of particles which have reached thermal equilibrium with the medium and emerge therefrom through apertures in absorbent collimators 14. Preferably the medium is provided with a central bore 12 from which the particles reach the detector and it requires to act as an effective moderator of particle energy to reduce this to thermal equilibrium in a reasonable distance. The generator may be a reactor or pile, a Van de Graaff generator, a cyclotron or radio-active material such as radium chloride mixed with beryllium in powder form. Preferably the neutrons are passed through a moderator, such as ice, to reduce their energy to equilibrium with ambient conditions before they are applied to the medium. The detector may either comprise indium foils and a device for measuring their radioactivity when bombarded by neutrons or a boron trifluoride proportional counter, the electrical pulse output in either case being fed to operate a counter or chart recorder. In testing thin bodies it is necessary to ensure an adequate neutron path within the medium (Fig. 2, not shown). Instead of determining the energy of particles leaving the medium the velocity distribution may be determined. One method of doing this involves the use of two discs rotating in unison on a common shaft and having angularly displaced slots. The slot path is arranged to intersect the particle path between the medium and the detector and by varying the speed of shaft rotation a curve of velocity distribution can be obtained. In a simpler method absorbers (as indicated at 19) of varying thickness are inserted in the particle path. A plot of absorber thickness against the logarithm of the detector counting rate has a straight line portion whose slope is inversely proportional to the square root of the absolute temperature. The layout of a practical apparatus is indicated in Fig. 3 where a Van de Graaff generator directs neutrons through liquid nitrogen chambers 30, 32, one within the other, to an ice block 34 having a bore 35 viewed by proportional counter 40 through pin-holes in boron plates 44. Specification 817,752 is referred to.

Title: Improvements in folding hoods for vehicles
IPC: B60J7/12
Filed: 1939-05-16
Abstract: 528,831. Vehicle hoods. MOTOR STATE PRODUCTS CO. May 16, 1939, Nos. 14560 and 14561. Convention dates, May 19, 1938, and Jan. 27, 1939. [Class 108 (i)] A foldable vehicle hood comprises a header 15 connected by a hinged cantrail 23, 24 pivoted at 33 to a rear pillar 34 of a main bow 17 hinged to a bracket 14 on the vehicle at 13, an extension beyond the pivot 13 being connected to a spring 37 or power operated device. An extension of the rear cantrail 24 is pivoted at 40 to a lever 39, 41 hinged at 12 to the bracket 14, the arm 41 being pivoted to a rear bow 18. A hinged prop strut 43, 46 is hinged together at 11 to bracket 12 and at 33 to pillar 34 an extension of the part 43 being pivoted at 44 to a link 26 pivoted at 27 to cantrail 23. Toggles 28, 29 pivoted at 30 to cantrail 23 and at 31 to link 26 support an auxiliary bow 19. A rear auxiliary bow 20 is pivoted at 47 to bow 18. When hood is to be collapsed the movement of header 15 breaks the cantrail joint and link 26 moves the end of prop 43 to break prop joint 45. In a modification, Fig. 7 (not shown), the link 26 is pivoted to cantrail 23 and the link 39 is pivoted on link 46 of the prop joint, another link pivoted at 40 is connected by a pivot joint to bow 18, the bow having a common pivot with bow support 34. In a further modification Fig. 10 (not shown) a similar linkage system is used but the link connecting the bow 18 and 40 is dispensed with.

Abstract: 1,015,532. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. April 11, 1963 [April 16, 1962], No. 14602/62 Heading H1K. A semi-conductor device with one electrode at one plain face and another electrode at a further face of the semi-conductor is mounted on a thin insulating plate by joining the plain face to an area of metallic film deposited on the plate, the other electrode being connected by a wire to another separate area of metallic film, and the whole assembly is then encapsulated in a hardenable plastics material. In one embodiment (Fig. 1) an NPN silicon transistor 10 formed by epitaxial planar growth has a P- type base 10 and N-type emitter 14 formed by double diffusion into an N-type region 12 through holes, etched by photo-lithographic techniques, in a silicon dioxide layer 15, with aluminium film 18 providing base and emitter electrodes. The transistor is mounted on one end of a thin glass plate 31 (Fig. 3) on which has been vapour deposited gold-chromium stripes 32, 33, 34. Collector connection is effected through the N+ region and emitter and base connections are made by thin gold wires 35, 36 which may be thermo-compression bonded to the stripes or jointed thereto by a silver loaded epoxy resin. The whole assembly is then encapsulated in a mass of resin or glaze. In a further modification (Fig. 7, not shown) a further lead is provided extending out from each stripe through the mass of encapsulating resin which in this case covers the whole of the glass substrate. The invention is applicable to diodes, matched transistors (including integral resistors and capacitors in the semi-conductor material). The substrate may be glass, mica, ceramic or silicon.

Title: Improvements in or relating to carbon black
IPC: C09C1/56
Filed: 1935-05-20
Abstract: A readily dispersible carbon black is obtained by precipitating an alkaline earth napthenate from an aqueous solution of a soluble napthenate in the presence of the carbon black, preferably in an amount between 1 and 10 per cent of the carbon calculated on the naphthenic acid used.  The black may be suspended in an aqueous solution of a alkali metal or ammonium naphthenate and precipitated by the addition of an alkaline earth metal salt, e.g. barium chloride, preferably at a raised temperature; or the black may be suspended in the alkaline earth metal salt solution, the soluble naphenate being added.  The product is readily dispersed in non-aqueous vehicles, e.g. mineral solvents, resins or nitrocellulose solvents, and their apparent density is increased. They are particularly suitable for printing inks, lithographic varnishes, or lacquers made from natural resins or containing cellulose derivatives or synthetic resins, particularly of the polybasic acid-polyhydric alcohol type, or for compounding rubber and other plastic compositions.
