Title: Improvements relating to the treatment of liquids which contain solid matter
Filed: 1949-08-26
Abstract: 661,443. Wet grinding. NORDELL, C. H. Aug. 26, 1949. [Sept. 24, 1948] No. 22240/49. Class 59. [Also in Group I] Lumps of solid matter flowing in sewage in a channel are comminuted by apparatus comprising a screen placed across the channel, a transfer and comminuting unit on the upstream side of the screen for removing solid matter therefrom and comminuting it away from the screen and means for causing the screen to be periodically swept by the unit. The screen is formed from channel bars 23 arranged with the flange portions directed upstream and placed horizontally with their ends clamped between upright channel irons 9, 10 within recesses on each side of the channel 2, 3 through which sewage flows. The lower part of the screen is formed by a plate 21 secured at the bottom of the sewage channel 2, 3 between horizontal channel irons attached to the upright channel irons 9, 10 and embedded in concrete so that slopes 19, 20 are formed on each side of the screen. Brackets 33 secured to the upright channel irons 9, 10 and the sides of the sewage channel 2, 3 are each provided with a bearing 34 for a cross-bar 35 which is positioned above the screen and on which is slidably mounted a housing 38. An arm 43 extending from the housing 38 over the cross-bar 35 is provided with a pinion 45 which is driven by a motor 44 carried by the arm 43 and which engages a rack 37 secured to the cross-bar 35 so that the housing 38 may be moved across the screen. Trip switches at the ends of the cross-bar 35 reverse the motor 44 automatically. The housing 38 contains a vertical shaft 51 rotated by a motor 53 the lower portion of the shaft 51 projecting beyond the casing 38 carrying toothed annular discs 75 separated by spacers 77. Each disc 75 is arranged so that it projects within a channel of a bar 23 forming the screen. Each spacer 77 is covered by a collar with a roughened surface for scraping the screen. Combs 89 of hardened steel having serrated teeth are attached to a second vertical shaft 52 projecting from the housing 38 and converge towards the first vertical shaft 51. The lower end of the shaft 52 is rigidly connected with a friction shoe 69 which engages a guide strip 72 mounted on the plate 21 forming the lower part of the screen. The drag produced between the friction shoe 69 and the guide strip 72 causes the shaft 52 to turn so that only one comb 89 co-operates with the discs 75 and spacers 77, the combs being used alternately each time the screen is traversed by the housing 38 and shoe 69. Engagement between adjustable studs 64, 65 (Fig. 7), which are carried by a flange 66 on the shaft 52, with stops 62, 63 mounted on the underside of the housing 38 controls the amount by which the shaft 52 can oscillate. For inspection or replacement purposes the shafts 51, 52 and the members attached to them may be lifted out of the sewage by rotating the cross-bar 35 in the bearings 34. Counterweights 47 are provided.

Abstract: 1,059,300. Gyroscopic apparatus; photo-electric systems. CSF - COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 25, 1965 [May 27, 1964], No.22260/65. Headings G1A and G1C. A gyroscope comprises a casing 2 rotated about an axis 11 in bearings 21, 22, the casing enclosing a cavity 24 containing a liquid e. g. mercury or gallium, which forms a cylindrical surface 31 on rotation of the casing, combined optical and photo-electric system being provided for detecting angular deviations between the axis 11 and the axis of rotation of the liquid due to changes in orientation of the casing 2. The detection system comprises a source of light 50 and a collimator 52 to direct a beam of light on to a semi-reflecting mirror 54, the light passing parallel to the axis 11 to conical reflector 4. This reflects the light on to the surface 31 of the liquid, back to the reflector 4, thence through the mirror 54 to two crossed pairs of prisms 55, 56 and 57, 58, (Fig. 2) the light frame each prism being reflected from an associated mirror 65 to 68 on to a photo-cell 75 to 78. The prisms are symmetrically disposed with respect to the axis 11. Any deviation between the axis 11 and the axis of rotation of the liquid will be detected as two component angles in the planes 11.x and 11. y (Fig. 2) defined by the dispositions of the pairs of prisms 55, 56 and 57, 58. Changes in orientation of the casing 2 then produce a corresponding difference in the outputs from the photocells in each pair due to changes in total internal reflection in the prisms. The photo-cell outputs may be used in a follow-up control system arranged to cancel any detected angular shift.
