Abstract: 1,198,223. Suspensions for the granulation of phosphate ore. KNAPSACK A.G. 10 May, 1968 [12 May, 1967], No. 22317/68. Heading C1A. Sprayable suspensions which are used for the granulation of fine particulate phosphate ore and consist of 8-30% clay, 15-30% electrofilter dust, 45-65% total solid matter, phosphate fine dust and one or more condensed phosphates are produced by preparing a clay sludge containing 0À2 to 1À0% of one or more alkali metal phosphates and adding this sludge to a suspension made from the other components above. A clay sludge which has a solid matter content of 35 to 60% is formed by introducing 35-60 kg. of clay with agitation and pumping into water and/or scrubbing water from wet dust collectors of a phosphate ore-dressing installation, the water being at 40 to 90‹ C., mixing the resulting sludge with one or more condensed sodium phosphates and agitating for 0À5 to 2 hours.

Filed: 1966-05-19
Abstract: 1,127,032. Colour analysis. CHESLEY F. CARLSON CO. May 19, 1966, No. 22371/66. Headings G2J and G2M. A method of analysing the dot sizes of a multicolour half-tone object comprises the steps of analysing the colours of the object in turn by superimposing an image of the object on a uniform half-tone screen of the same periodicity as the image, the screen being disorientated from the image of the colour to be analysed by a few degrees. Apparatus for carrying out this method comprises a light proof casing with an open end for application to the object 22, a light source 30 arranged to illuminate the object through said open end, a viewing screen 90, a half-tone screen 86 adjustably positioned adjacent the viewing screen 90, and a lens 46 for projecting an image of the object on to the screen 86. The lens 46 and screen 86 are located at opposite ends of a light-proof bellows 50. The screens 90, 86 are supported on deck 48 which is carried by support rods 52, 54. Focussing of the lens on the screen 86 is effected by rack and pinion mechanism mounted on the support rods 52, 54. The screen 86 is seated in an annular plate 69 which is adapted for angular adjustment about the projection axis by means of annular raceways provided on the deck 48. A motor-driven fan 32 cools the apparatus.

Title: Apparatus for recognition of instruction codes
IPC: G06K7/10
Filed: 1972-05-12
Abstract: 1425024 Discharging articles from a conveyer at predetermined points HIRD-BROWN Ltd 27 March 1973 [12 May 1972] 22415/72 Heading B8A [Also in Division G4] Discharge of coded articles 3 from a conveyer 2 at appropriate destinations is effected by the reading of the code by a television camera 1. The signal generated thereby is compared with a standard signal, and if the signals agree a servomotor is energized to cause the discharge. As described, the signal from the camera 1 is fed to a monitor screen 4, to a video gate 5, and to a line counter 7. The latter opens the gate 5 at the time an output is obtained, so that the signal then passes to a comparator 12 via a shift register 10, connected to a clock pulse generator 11. The destination code is set up on switches 17, and is also fed into the comparator. The latter generates an output pulse to operate the conveyer mechanism. In an alternative arrangement, the video gate is held open for at least ten lines so as to ensure that blemishes on the article are not confused with the code. The code setting switches 17 may be manually set, or may be set by means of magnetic or punched tape, magnetic disc, punched cards, computer, jacquard-type patterns, or a rotatable set of cams.

Title: Liquid fuel regulating means for prime movers
Inventor: LAWRENCE OWEN NAPIER
IPC: F02D3/02
Filed: 1953-08-14
Abstract: 749,783. Gas turbine plant. LUCAS .(INDUSTRIES). Ltd., J. Aug. 12, 1954 [Aug. 14, 1953], No. 22440/53. Class 110(3) [Also in Group XXIX] The liquid fuel regulating means for jet propulsion engines and gas turbines described in Specification 677,138 is modified by replacing the restricted orifice in the main fuel conduit by a variable throttle c actuated by a fluid operated servo mechanism in dependence on the blower inlet pressure and by replacing the third restricted orifice referred to in claim 1 of Specification 677,138 by a manually or automatically actuated throttle z the pressure difference across which is utilized to control a liquid-operated servo-mechanism adapted to operate means for varying the rate of supply of fuel to the burner. The throttle c controls the passage of fuel through a throat b from a supply pipe g to a discharge pipe h leading to the burners. The throttle is actuated by a servo piston e controlled by a leak-off valve k carried by a lever m which is loaded by a spring d connected to the throttle and passes through a seal n into a chamber o containing an elastic evacuated capsule p responsive to blower inlet pressure. The inflow and outflow sides of the throttle c are connected by passages u, w to the opposite sides of a diaphragm t. The diaphragm t carries a valve y controlling the inlet to a passage x leading to a discharge flow exit and controlled by a manually operated throttle z. A flexible diaphragm 7 subject to the pressures on opposite sides of the throttle z operates a spring-loaded lever 8 carrying a leak-off valve 12. The valve 12 controls a ,spring-loaded servopiston 19 supplied with motive fluid through an inlet 15. The piston 19 operates fuel control means through a rod 21. In a modication, the leak-off valves k, 12 are replaced by baffles adapted to interrupt the flow of fluid across a gap in the supply passage to the servo-cylinder. In a further modification the fixed restriction v in the passage u is replaced by an adjustable throttle which may be operated manually or automatically. Thus it may be operated by an electromagnet the current in which is variable in response to temperature or some other variable factor associated with the fuel control system. The throttle z may also be operated automatically by the same means.
