Abstract: 1,022,306. Electrical filter networks; multiplex radio signalling. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 30, 1963 [Jan. 2, 1963], No. 51137/63. Headings H3U and H4L. A band-pass filter for passing a comparatively wide frequency range and also for suppressing a comparatively narrow frequency band adjacent to said wide range, comprises series branches I, II, each constituted by a seriesresonant circuit tuned to the mid-point of the wide range and a shunt branch comprising individual branches III, IV each comprising series-resonant circuits tuned to the narrow band, the branch IV being coupled across capacitor 35 forming part of branch III. The input signal which may bea television intermediate-frequency signal is applied to input terminals on the left and the output signal from which signals, e.g. sound carrier, within the comparatively narrow band have been suppressed appears across capacitor 21 which may be the input capacitance of a vision intermediate frequency amplifier valve, Fig. 3 (not shown). The corresponding sound carrier signal, i.e. the comparatively narrow frequency band, is developed across capacitor 41 which may be the input capacitance of the sound I.F. amplifier. To obtain the band-pass characteristics inductors 13, 23 and 33, 43 may be inductively coupled though this is not essential and in the preferred embodiment inductive coupling is not used. Resistor 40 serves as a neutralizing component to reduce the sharpness of the narrow frequency band.

Title: Improvements in or relating to micrometers
IPC: G01B3/18
Filed: 1946-01-15
Abstract: 600,847. Micrometer gauges. GILMORE, G. E. H. Jan. 15, 1946, No. 1329. [Class 106 (ii)] A micrometer gauge, having means whereby the setting of the gauge to a definite position according to an " inches " scale will permit the corresponding metric measurement to be read off, is characterised by having its thimble geared to an adjoining thimble rotatably mounted on a second sleeve secured to the frame. The two sleeves H and M<1> are secured to a frame A and co-operate with rotatable thimbles G and M which are connected by means of gearing G of suitable ratio. The primary sleeve and thimble Hand G control the micrometer spindle F and are calibrated in English measure, while the auxiliary sleeve and thimble are calibrated in metric units. The micrometer anvil B may be secured with a set - screw E to the frame A, in any of four positions determined by lugs B', one of which is held against the inner face of the frame A by a spring D. The lugs B<1> are spaced one inch apart and for this reason, the metric sleeve has four longitudinal scales-from 0-25 mm., 25-50 mm., 50-75 mm. and 75- 100 mm.-each scale being spaced 0.4 of the circumference of the sleeve from the consecutive scale and being longitudinally displaced by 0.4 mm., since 25.4 mm. equal one inch. Each longitudinal scale line on this sleeve is doubled to act as a simple vernier. Means for taking up wear (not described) may be employed and a locking-nut for the spindle F is provided which acts on the frame A, the latter being split to form two eccentric semi-circular flanges which are relatively moved by rotation of the locking-nut to clamp the spindle.

Title: Improvements in or relating to variable speed gearing
IPC: F16H33/02
Filed: 1929-01-14
Abstract: 304,151. Schieferstein, G. H. Jan. 14, 1928, [Convention date]. Change - speed gearing comprises an unbalanced weight 4, Fig. 1, rotated from a flexible driving- shaft 1 inside a friction drum 2. The drum 2 is caused by centrifugal action to wobble round inside a resilient track 5 secured to a fixed wheel 6. The drum 2 transmits a reduced speed through an Oldham-type coupling 8 to a shaft 10, which speed varies automatically with the load. The weight 4 is adjustable, and the amplitude of the movement of drum 2 into the resilient track 5 varies automatically. The track 5 may alternatively be secured to the drum 2 and run with deformation inside wheel 6. Alternatively, the shaft 10 may be held and the wheel 6 driven. In such an application in which the wheel 6 is the road wheel of a tractor, the impulses of the weight 4 towards the ground are stated to increase the grip of the wheel, and therefore the tractor force. A suitable form of Oldham-type coupling connecting the drum 2 to a disc 9 on the shaft 10 is shown in Fig. 2. A floating torque.-transmitting square 8 slides in one direction between two pairs of guide rollers 14 on the drum 2, and in a perpendicular direction between two like pairs of rollers 15 on the disc 9.

Title: Improvements in or relating to methods of producing photographic records
IPC: B64D17/52
Filed: 1947-01-17
Abstract: 678,912. Photographic diazotype processes. NAAMLOOZE VENNOOTSCHAP PHILIPS GLOEILAMPENFABRIEKEN. Jan. 17, 1947 [Jan. 21, 1946], No. 1599/47. Drawings to Specification. Class 98 (ii). A method of producing a photographic physically developed metal record on a hydrophilic material which has been treated with a light-sensitive diazonium compound and a metal compound which is reducible in an aqueous medium so that the sensitive material has a moisture dependent gamma value, i.e. a variation in the moisture content of the material between the limits of 30 per cent to 100 per cent relative humidity is capable of effecting a variation in the ratio 1 : 1.2 in the gradient of the characteristic density curve for the density values 0.4 to 1.5, is characterised in that the sensitized material is exposed to light and the gamma is controlled by adjusting the light intensity and duration of the exposure, preferably with the moisture content of the material in excess of its equilibrium value of an atmosphere of relative humidity 65 per cent at 20 C. The gamma may also be simultaneously controlled by adjusting the moisture content of the material at the moment of exposure as claimed in Specification 678,911. Records of different gradations, e.g. in copies of picture and variable width sound records, background and subject in portraits, sky and ground in landscapes, may be produced on a single material by exposing each of the different record areas with a different light intensity and duration of exposure, and the differently exposed parts may be developed together in a single operation. Successive scenes on a film, e.g. a newsreel, may be copied with different gradations as by providing the film to be copied with a control track which regulates by photo-electric means the intensity and duration of each exposure, as by controlling the distance over which the film is advanced at the same speed while effecting each exposure. The support for the light-sensitive compound may be transparent and preferably is wholly or partly regenerated cellulose, superficially saponified cellulose acetate, a water-absorbing layer such as albumin or a derivative thereof on a support which may or may not be moisture sensitive, or a hydrophilic polyamide. Typically a regenerated cellulose support is sensitized by soaking it in an aqueous solution of 1-hydroxy 2-diazonium 6-methyl benzene 4-sulphonic acid, mercurous nitrate, and nitric acid and after exposure to a high pressure mercury vapour lamp is washed and developed in an aqueous solution of metol, tartaric acid and silver nitrate. Specifications 481,826, 511,816 and 523,568 also are referred to.

A lockable coaxial tube or rod arrangement for supporting a hairdryer, a microphone, a lamp, a mirror, or camera for example, comprises an inner tube or rod 12 interfitting within an outer tube 11 so as to define an annular gap 20 of varying width therebetween, and wedging means which are formed by projections 22 on the periphery of an inner sleeve 16 integral with an outer sleeve 15 surrounding the outer tube and which are rotatable within said gap about the inner rod or tube to lock the inner tube or rod and outer tube in the desired position. The varying gap is produced by forming the upper outer tube end with two eccentric semi-cylindrical portions 19. A peripheral groove 24 is swaged in the outer tube to guide the inner tube therein. The outer sleeve 15 is serrated on its outer surface and four projections 26 are formed on its inner surface which engage in a peripheral groove 27 in the outer tube to axially position the inner and outer sleeves relative thereto. The integral inner and outer sleeves 15 and 16 define a unitary hand grip 10 which may be synthetic plastics. In a modification, Figs 4 and 5 (not shown), the peripheral groove 27 is omitted and webs 128 provided to prevent the outer tube resting directly on the annular bridging part 17 integrally connecting the outer and inner sleeves.

Abstract: 283,963. Compagnie Industrielle des Moteurs Ó Explosion (C.I.M.E.), and Perrier, D. Jan. 22, 1927, [Convention date]. Density separators.-A separator for the treatment of liquids or gases has a number of baffles which divide it into a series of communicating annular chambers, and the fluid during its passage through the apparatus is subjected to the same centrifugal force a number of times. A series of conical frusta 1 - - 5, Fig. 1, are engaged at their larger diameter with similar frusta 6 - - 10 and the two sets are locked together by any known means. Annular chambers 11 - - 14 are thus formed and adjoining chambers communicate at the upper or lower end of the apparatus as shown. The liquid or gas to be treated enters through a duct 19 in the shaft and the densest elements are separated out in the chamber 20. The fluid passes through the apertures 16 into the outermost chamber 11 and the remaining heavy elements are deposited upon the outer wall until they discharge through the apertures 17. The fluid passes on through the remaining chambers where it is subject to further separation and is finally discharged through orifices 18 in the upper wall. In the modification shown in Fig. 3, the central part of each chamber is cylindrical in form, and the apertures 17 are made in the conical wall of the chamber; the discharge orifices 18 are made in the shaft. The dotted lines indicate positions of equal centrifugal force in different chambers.
