Abstract: 696.516. Mixing appliances. COURTAULDS, Ltd. April 16, 1952 [April 17, 1951] No. 8910/51. Class 86  A churn for use in viscose production comprises a rotatable drum having a discharge opening and a ventilating shaft comprising a hollow structure having four or more-smooth planar faces so arranged that only one face is hidden from direct view when the shaft is inspected through the discharge opening. In Fig. 1, a drum 1 mounted on trunnions 2, 3 so as to rotate in the direction of the arrows and having a door 4, is provided with a hollow ventilating shaft 6 which is in communication with a conduit 5 passing through the trunnion 3 and connected with an evacuating line 10. The shaft 6 has five smooth faces 6a-e, is triangular in cross-section and the face 6a is closely spaced from the drum end wall 1a and makes a small angle' with it whereby cellulose crumbs will not readily enter the space so defined, or adhere to the face 6a. The four faces 6b-e are at such an angle that they can be seen and scraped clean by an operative wielding a paddle or rake through the door 4. The shaft 6 is displaced from the vertical by about 40 degrees in the direction of rotation of the drum. An opening 8 in the face 6b is covered by a removable perforated metal plate 9. A carbon disulphide supply line 11 runs along within the conduit 5 and shaft 6 and ends with a nozzle 12, Fig. 5, flush with the face 6c. It is possible to have a shaft having four or more than five faces. The shaft may have the form of a pyramid and have a triangular cross-section.

Title: Radar systems
IPC: H01Q3/30
Filed: 1971-04-07
Abstract: 1361681 Pulse radar; aerials MARCONI CO Ltd 30 March 1972 [7 April 1971] 8945/71 Headings H4D and H4A A known "within-pulse" scanning radar, Fig. 1, employs an arrangement of receiving aerials (e.g. horns) A 1  ... A n , frequency changers F 1  ... F n , respective local oscillator frequencies LO 1  ... LO n  differing successively by (<SP>1</SP>/t) where t is the radar pulse duration, filters S 1  ... S n  each of bandwidth (1/t), and the filter outputs being connected together to form utilization signal U. This is stated to lead to spurious signals from grating lobes, particularly where elevation or height finding is taking place. According to the invention spurious signals are reduced by combining the filter S outputs into K groups (where K is an integer greater than unity), employing switched phase shifters in the outputs of at least some groups and arranging that the aerial spacing d is given by: where 0 is the scanned angle, and # is the wavelength. Fig. 5 shows the system when K=3, phase shifters PS 1, PS2 each introducing a phase shift of 0 degrees, 120 degrees, 240 degrees as directed by switches SW1, SW2 actuated as described in the Specification. The invention is applied to a system in which a conventional azimuth scanning pulse radar, including an electronic circular displayed marker positioned by a joystick, is supplemented by a withinpulse scanning array (A, Fig. 6, not shown) which is tilted and rotated in azimuth synchronously with the conventional azimuthscanning aerial (2), the output U (see Fig. 5) being gated (9) under joystick (6) control such that signals pass only corresponding to the marked targets on the usual P.P.I. display (4); the signals passing through the gate are integrated, and elevation or height information is extracted and displayed in known manner.

The peripheral support member of a shadow mask electrode in a colour television tube has an axially extending sidewall portion 51 of varying height, such as to conform to the curvature of the shadow mask periphery,which sidewall portion has at its end furthest from the screen an inwardly directed flange 55, which prevents the impingement of the beam upon the inner surface of the sidewall, and the width of which varies linearly with the height of the sidewall, whereby to prevent undue interception by the flange of the electron beam when the latter is directed at the corners of the screen. The inner rim 59, 61 of the flange constitutes a plane directed at such an angle, #, to the tube axis that electrons which impact and are reflected from the rim do not impinge upon the screen. As shown in Fig. 8, the leading edge 59 of the flange rim determines the maximum deflection angle # for impingement of the beam upon the screen; to prevent electrons which are deflected through an angle which exceeds # by γ from being reflected at such an angle as to impinge upon the screen, the angle B is chosen not less than

Title: Improvements in centrifugal type dust separators
IPC: B01D45/14
Filed: 1928-03-26
Abstract: 304,952. Crago, C. H., and Hamilton, A. E. March 26, 1928. Pneumatic separating.-Centrifugal apparatus for extracting dust, soot, flour, or other solid particles from gas, has one or more extraction fans in peripherally slotted casings arranged in a closed dust casing, and a centrifugal fan maintains the flow of gas through the apparatus. In the form shown, the apparatus is applied for grain cleaning and two extraction fans 12, 13 are employed. These fans, with the centrifugal air fan 10 are mounted on the shaft 11; the fans 12, 13 operate in casings 21, with dust passages 26 through which separated dust can pass into the chamber 27. The extractor fan blades are shrouded, the fan 12 having a ring 64, Fig. 4, on the suction side, and a disc 66 on the discharge side; the diameter of the disc is slightly larger than the internal diameter of the ring. The chambers 15, 16 on the suction side of the extractor fans are in communication with the discharge side of the fan 10 through passage 19 and ports 17, 18. The exit from the casing 14 of the fan 10 is controlled by an adjustable flap 20, Fig. 2. The grain to be cleaned enters the shoot 40 and falls on to a tray 41 from which it is showered through the chamber 43. It passes through the chamber 44 and grain cleaner 39 to the hopper' 45 from which it is showered to the box 49 for discharge. Clean air from the fan 10 is blown across the showers of grain in the chambers 43, 49 and takes up the dust; the dust-laden air then passes to the suction chambers 16, 15 where the air from the fan 10 is also admitted through the ports 18, 17. The mixture enters the fans 13, 12 and the dust is thrown into the casings while the cleaned air passes through the fan 10 for circulation again. The dust passes through the passages 26 in the casings into the dust chamber 27 from which it is moved by the conveyer 60 to the outlets 28, 31. The two extractor fans may be arranged in series instead of in parallel, and may have sleeves to adjust the sectional area of the dust passages.

Class 97(1) In an interferometer of the Nicholson type in which a light beam is divided into two beams which are reflected back along their paths by two reflectors to produce interference effects the two reflectors are fixed together back to back and the two beams are so directed to the reflectors by suitable mirrors or prisms that corresponding rays of the two beams are incident on the reflectors on opposite sides of the centre line thereof to make to optical paths difference between the two beams independent of any tilt of the two joined reflectors. As shown light from a collimating lens 10 is divided by a semi-transparent reflector 11 into a reflected beam which passes to a compensator plate 13 and mirrors 12 and 14, and a transmitted beam which passes to inclined reflectors 16 or 17. By this arrangement the two beams are incident along the same axis but in opposite directions on the double reflector 15 and are each reflected by it back along their respective paths to be recombined by the reflectors 11 to pass to a lens 18 to produce interference effects. The mirrors are so arranged that light from a point A in the original beam is incident on the reflector 15 at points A in the divided beams spaced on opposite sides of the common axis of those beams to make the path difference independent of the tilt of the reflector 15. The mirrors may be replaced by prisms, a rotary compensating plate being provided adjacent the reflector 15.
