The alkali metal compound used is preferably a hydride or amide or an organolithium compound and preferred solvents are benzene, toluene xylene, monochlorobenzene, dimethylacetamide, diethylacetamide, dimethylformamide, dioxane, dimethylsulphoxide and mixtures thereof. Quinazoline derivatives for Formula (I) wherein R, R<SP>1</SP>, R<SP>2</SP> and R<SP>3</SP> are as defined for Formula (V), are prepared from the 2-(N-monosubstituted amino)-phenyl ketones of Formula (V) by reacting the latter with a C 1-4  alkyl haloformate or a benzyl haloformate to give a carbamate derivative of Formula (VI) wherein R 6  is a C 1-4  alkyl group or a benzyl group, and then heating the compound of Formula (VI) with ammonia. The quinazoline derivatives of Formula (I), which are said to include novel compounds, possess pharmacological properties, particularly anti-inflammatory and analgesic effects with lower toxicity than phenylbutazone. Many examples of compounds of both Formulµ (I) and (V) are listed together with melting point data. The specific example describes in detail the preparation of 2-ethylamino - 5 - chlorobenzophenone and 1 - ethyl- 4-phenyl-6-chloro-2(1H)-quinazolinone.

Title: Improvements in or relating to colour picture tubes of the shadow mask type
IPC: H01J9/14
Filed: 1969-11-26
Abstract: 1,224,850. Making screens. ZENITH RADIO CORP. 26 Nov., 1969 [28 March, 1969], No. 57895/69. Heading B3A. [Also in Division H1] A shadow mask for a colour television tube comprises a metal plate 10, Fig. 3, containing an array of apertures 11 opposite each of which is provided a recess 11a of similar shape. The shadow mask is used to produce a fluorescent screen by a photo-resist process, and after processing the screen the mask is etched to enlarge the apertures 11. In one example a sheet of cold rolled steel is coated on each side with a photo-resist and illuminated through a mask to provide a dot pattern on each side, and after etching in ferric chloride apertures are formed as shown in Fig. 3. The mask is used in photoresist processes to form on the screen firstly a dark area between phosphor dot areas, and then the three sets of phosphor dots, after which the screen is aluminized. The mask is then subjected to a second etch which enlarges the apertures and reduces the thickness of the mask. The initial thicknesses E1 and E2 may be 7 mils and 2¢ mils, the diameters D1 and D2 9 mils and 22 mils, the final thicknesses 5 mils and 1¢ mils, and the final aperture diameter 16 mils. The apertures need not be of uniform size, but may increase in diameter with radial distance from the centre; they may also be of elongate form (Fig. 5, not shown) so that the mask becomes a grid and the screen is of the multi-line type.

Abstract: 1322190 Dyeing apparatus F RIGACCI 8 Dec 1970 [23 Dec 1969] 58138/70 Heading D1L A yarn dyeing plant comprises a conveyor for receiving the yarn, means for applying a coloured dye to the yarn, means for applying a second coloured dye to the yarn, means for fixing the dyes by raising the temperature means for washing the yarn whilst in motion on the conveyor, and means for drying the yarn. As shown a conveyor 1 is loaded with yarn by means of endless web 11 and carried to dyeing zone A where dye is applied through tubes 17 which are raised and lowered in cyclic fashion, the structure being such that eccentrics 25 and connecting reels 21 cause the tubes 17 to press down on the material and accompany it forwards on the downstroke but do not contact the material on the return stroke. This produces a flammÚ dyed effect. After dyeing, the dye is fixed by heating in steam chamber 7 and the fixed dye washed in region C by liquor supplied from nozzles 35, the liquor being worked in and out of the yarn by squeezers 27, operating in a fashion similar to that of dyeing tubes 17, in conjunction with support surface 33; both squeezers 27 and support 33 being perforated. After washing the yarn is dried in oven D.

Abstract: 1,247,897. Reactors. SIEMENS A.G. 23 Dec., 1968 [29 Dec., 1967], No. 61164/68. Heading G6C. In a pressurized water reactor, the reactor and heat exchangers are supported, inside a prestressed concrete vessel, from the steel cover-plate. The core 5, thermal shield 24, heat exchanger steam generator 6, and the pressurizing tank 4, are supported by the steel cover 2 inside the reinforced concrete container 1. The reactor coolant water circulates upwards through the core and downwards through the exchangers 6, and convection circulation may be supplemented by a pump 62. The coolant system is pressurized, to prevent boiling, by the pressure generator 42, where the vapour pressure is controlled by electric heating elements. The reactor assembly is enclosed in the steel cylinder 21, pressure equalization being effected by the flow of cooling water in the space 3, which prevents an excessive temperature rise in the concrete. The oblique control rod tubes 7 extend through the cover 2 which is sealed to the steel lining 16
Patent GB-724527-A (GB)
IPC: B65B1/46
Abstract: 724,527. Automatic control systems. EXACT WEIGHT SCALE CO. March 26, 1952 [March 29, 1951], No. 7760/52. Drawings to Specification. Class 38 (4). In a control system electronic means produce voltages dependent on a controllable physical characteristic of each one of a series of successive articles, the voltages being applied to condensers by the articles being tested and the condensers being connected together to obtain an average control factor. The invention is applied to a beam-type weight-checking machine of the type in which the weighing beam moves the plates of an electric condenser to vary the frequency of an oscillator combined with a discriminator circuit to produce a voltage dependent on the deviation of the weight of each of a series of filled packages passing through the machine. The deviation voltages are utilised in the manner described below to control the filler spout of a dispenser from which the packages are filled before being transported on a conveyer to the weighing section of the machine. As each package leaves the weighing section of the machine a beam of light associated with a photocell is interrupted. Electrical impulses are thus produced and a stepping switch is operated at each impulse to charge a condenser to the weight deviation voltage corresponding to the package producing the impulse. Five condensers so charged are then automatically connected in parallel to produce an average weight-deviation voltage which serves to control the filler spout of the dispenser. The arrangement operates continuously to produce an average weight deviation voltage for each successive group of five packages. In a modification, according to the position of a manually operated switch, four or nine condensers may be charged in succession so that the weight deviation of a corresponding number of packages may be averaged. In this arrangement the weight deviation of one package is missed between the groups averaged. In another modification further condensers are charged to the average deviation voltages of successive groups and a group average obtained by paralleling these condensers. In this manner an average of two, five or ten groups of five may be obtained.

Title: Correlation of representations of a reference and a scene
Inventor: THORSKOV JAN CHRISTIAN
IPC: G01S3/786
Filed: 1978-10-11
Abstract: The arrangement comprises stores 2, 4 for storing a current representation of a scene, and a reference representation, a correlator 5 for correlating the representations, a variance evaluator 6 and control devices 3, 7 for controlling the selection of the current representation and the updating of the reference representation.

If the variance is less than a first threshold and the reference representation is to be updated, then a new reference representation of increased size is selected. Updating takes place if (i) a predetermined update criterion independent of variance is met, (ii) the variance is less than a second threshold less than the first, (iii) the variance is less than the first threshold for a preset time. <IMAGE>
