Abstract: 728,868. Drying coal &c. DORR CO. April 23, 1953, No. 11262/53. Class 34 (2). In the drying of coal &c. the drying takes place in a fluidized bed and the finer particles which are separated from the mass are burned under pressure to furnish 'the heat for the drying operation. The apparatus 20, having an outer shell 34, bottom coned plate 50 and top plate 25 is divided into a heating zone A and a drying zone B. An apertured plate 52 supports the bed of material 43 in zone A and another plate 71 supports the bed of material 36 in zone B. Wet coal or other material is fed to hopper 21 and thence via conveyer 24 to bed 36 where it becomes fluidized by hot gases rising from zone A, the bed 36 being composed principally of inert material such as ceramics, metals, sand &c., or a coarse fraction of the material being dried. The majority of the coal particles are entrained in the hot gases and pass via pipe 26 to separator C where all but the finest particles are removed and pass through pipe 32 via valve 74 to storage hopper 65. The fine particles are carried through pipe 28 to separator D where they are collected and pass via pipe 33 and fitting 61 to hopper 63 or to hopper 58 if valve 62 is closed when too much material is received in hopper 63. Fine particles pass from the hopper 63 to feeder 54 and into a gas stream passing through conduit 81 controlled by valve 80 by which stream they are conveyed to zone A in which the bed 43 is of fluidized coarse inert material. The temperature of the heated uprising gases is controlled by means of an air bleed-in pipe 75 controlled by valve 76. Ash may be removed from zone A via pipe 42 and the gas for fluidizing the beds is supplied via pipe 47 and windbox 51. Particles in zone B too large to be fluidized may be withdrawn through pipe 37 into hopper 65.

Title: Improvements in or relating to lenses
Inventor: STIRLING JOHN FOSTER
IPC: G02B3/08
Filed: 1959-04-06
Abstract: 902,535. Fresnel lenses. JOBLING & CO. Ltd., JAMES A. April 6, 1960 [April 6, 1959], No. 11597/59. Class 97 (1). A Fresnel lens has a plurality of concentric prisms which each lie in the position of minimum deviation with respect to rays incident on a prism from a source located at the principal focus of the lens and the corresponding refracted rays. In this lens the hypothetical surface containing the points of intersection of said incident and refracted rays is defined by the relationship r=Kq, where r (not shown) is the distance of any given point on the surface from the principal focus, K (not shown) is the distance from the principal focus to a point where said surface is cut by the optical axis and q is a function of the angle of deviation D (not shown) at said point and the refractive index of the lens material, such function being given in the Specification. One example is given in the Specification of a method of designing such a lens from a table of data giving the values of q (not shown) for corresponding values of the angle D taking the refractive index of the lens material to be 1.51. From these values, the value of K is found and any number of corresponding values of r and D could then be calculated so that the sectional shape of the hypothetical surface could be drawn in. The smooth surface on the side of the lens away from the principal focus is then drawn parallel to the hypothetical surface and displaced therefrom by a distance equal to half the desired mean thickness of the lens. The inner surface of each prism P1 to P4 is then drawn in at an inclination to the vertical plane through the optical axis which is necessary to give minimum deviation for rays incident thereon from the principal focus F. The lens as so designed may be made by pressing hot fluid glass in suitable moulding equipment. One example of a finished lens is given in the Specification.

Title: Improvements in or relating to receiving devices for image transmission
IPC: H04N1/00
Filed: 1948-04-29
Abstract: 654,439. Copying-telegraphy. PHILIPS ELECTRICAL, Ltd. April 29, 1948, No. 11770. Convention date, May 2, 1947. [Class 40 (iii)] In an arrangement for recording received picture signals on a moving film a device is provided for indicating, by means of a mark on the film, the beginning or end of each complete picture, the device being controlled by a signal which is transmitted during the interval between two successive picture transmissions. The film 21 which is drawn from a supply roll 22 by means of rollers 24, 25 driven by motor M via the transmission system including the elements 33, 36, 41 and an electromagnetic clutch 30 has the images recorded thereon as it passes the point A, at which it is exposed to a light beam modulated by the received image signal and arranged to scan the film in parallel paths at right-angles to the direction of the film, after which the film passes, successively, a first and second marking device 26 and 27, contact devices 14 and 19 and a cutting device 28. The marking device 26, which is operated electromagnetically, is arranged to mark the film (e.g. to punch a hole therein) when the signal which is transmitted between images ceases and thereby indicates the commencement of a picture transmission. The mark thus produced serves to operate a contact-device 14 when the film passes thereunder and thereby operates the second marking device 27 which is arranged to mark the film, on the edge opposite to that marked by device 26, so that the second mark does not operate contact device 14, but does operate contact device 19, the latter device preparing the operating circuit of the cutting device 28 which becomes operative to cut the film after an interval which is determined by the closing of contacts d in the circuit of the cutting device. These contacts are operated by means of a cam 38 which is driven from the main transmission system through an electrical coupling 37 and arranged so as to rotate through a definite angle (determined by a stop, not shown) and then to return, on being released, under the action of a spring 40. To ensure that the film is cut in definite lengths (e.g. about 50 cms.) and, when no image signals are received, that the marking devices and the film moving and cutting mechanisms are rendered inoperative, a further series of contacts b1, b2, b3, operated by a cam 35, and a contact e, operated by a cam 38, are arranged to control the above devices and mechanisms through a system of electromagnetic relays (Fig. 2, not shown).
