Title: New metal complexes of monoazo dyestuffs and their production and use
IPC: C09B45/48
Filed: 1959-12-14
Abstract: The invention comprises cobalt and chromium complex dyestuffs wherein the metal atom is attached to one or two azo dye radicals of formula <FORM:0900354/IV (b)/1> in which R1 and R2 are a hydrogen or halogen atom or an alkyl or alkoxy group, or to an azo dye radical of the above formula and either to a radical of another ortho: ortho1-dihydroxyazo dye free from sulphonic acid groups or to a radical of a colourless complex-forming compound.  They are prepared by coupling in known manner a diazotised 2-alkoxyaniline with 1-(4-hydroxyphenyl)-pyrrolidone-(2) and metallising the azo dye so obtained, alone or in admixture with another such azo dye, or with another ortho:ortho1-dihydroxy azo dye free from sulphonic acid groups, with a cobalt- or chromium-yeilding agent.  If the complex so obtained contains less than 2 dye radicals per metal atom it may be reacted further with a colourless complex-forming agent or with an ortho-ortho1-dihydroxyazo dye free from sulphonic acid groups.  The dyes give red and violet dyeings or natural and synthetic polyamides. In an example the dye 1-amino-2 : 4-dimethoxy-5-chlorobenzene --> 1-(4-hydroxyphenyl)-pyrrolidone-(2) is prepared and converted into cobalt and chromium complexes in known manner.  Further examples are given, including the preparation of mixed complexes. Specification 692,073 is referred to.

Abstract: 1367368 Radiometer NORTH AMERICAN AVIATION Inc 6 Oct 1965 42468/65 Heading G1A A radiometer in which the detector is alternately exposed to a black body reference source and the source to be measured, and which is particularly intended for measurement of infrared radiation, comprises a stationary housing 20 mounted on posts 51, 52 the housing supporting a frusto-conical member 24 having a roughened black body reference surface 21, a radiation detector 12 producing a signal in a circuit 15, a hyperhemispherical aplanat lens 11 and a collimator lens 31. A thermal control Fig.4 (not shown) having a temperature-sensitive winding  41 and a heater winding 42 wound on the member 24 maintains the surface 21 at a constant temperature. A pair of shutters 71, 72 having a spherical surface and rotatable about a vertical axis Ac is supported between base members 61, 64 mounted by ball bearings 55, 56 on the posts 51, 52, the rotation being derived from a motor Fig.1 (not shown) operating on a gear 67. The sides of each shutter are vertical and each shutter subtends at the axis Ac an angle of 90 degrees Fig. 2 (not shown) in the horizontal plane including axis Al Fig.2 (not shown). The shutters 71, 72 are diametrically opposite to each other so that for each revolution of the shutter assembly the field of view in front of the lens 31 is obstructed for two periods of 90 degrees when the lens may receive radiation from the source to be measured. When the field of view is obstructed, the internal surfaces of the shutters act as reflectors for radiation from the reference surface 21 and reflect their radiation back on to the detector 12. Thus, the output from the circuit 15 is a repetitive wave having peaks corresponding to the radiation from the surface 21 and troughs corresponding to the source to be measured Fig. 5 (not shown).

Abstract: 1,116,844. Capacitive read-only memories. TELEMETRICS Inc. 11 Oct., 1965 [19 Oct., 1964], No. 43099/65. Heading G4A. In a capacitive read-only memory matrix having individual capacitor memory elements disposed at memory positions defined by the intersection of orthogonally disposed address and sense lines each of the capacitor memory elements is connected between a sense line and either an address line or a ground line in accordance with the stored information pattern. As shown, an array of capacitor elements 12 is formed by conductive plates on opposite sides of an insulating sheet 10, the lower plates being connected to sense lines 19 and the upper plates initially being connected to both address lines 15 and to ground lines 16. Binary information is stored by selectively drilling holes 21 to break the connection between the upper plates and either the lines 15 or 16. The lines ]5 and 19 are connected to transistorized select drive and translator circuits (Figs. 4 and 5, not shown) arranged so that lines other than those selected are maintained at ground potential. The output impedance of all sense lines 19 is thus uniform regardless of the information pattern stored and the signal-to-noise ratio is improved. A plurality of the plates 10 may be combined to provide a 3-dimensional matrix store (Figs. 3-5, not shown).

Title: Vibration compaction
IPC: C22B1/02
Filed: 1960-12-21
Abstract: 925,186. Nuclear fuel elements. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 21, 1960 [March 7, 1960], No. 43895/60. Class 39 (4). A nuclear fuel element is prepared by compacting a powdered ceramic nuclear fuel within a metal container by vibrating the container at its resonant frequency and varying the frequency of vibration to follow the resonant frequency change caused by compaction of the powder. As an example of the preferred mode of carrying out the invention, a weighed amount of crushed and screened uranium dioxide is poured into a Zircalloy-2 tube to which a lower end cap has been welded and the tube vibrated at 1000 c/s. on a moving coil vibrator at low power. The frequency is rapidly reduced until the resonant frequency of the tube at about 180 c/s. is reached whereupon rapid densification occurs and full power is turned on, the frequency being swept slowly back and forth across the resonant frequency several times (Œ100 c/s.), the resonant frequency changing to about 240 c/s. as the particles densify. The frequency is then lowered to about 100 c/s. and then again raised to the resonant frequency and swept across it several times. This is followed by a raising of the frequency until a harmonic of the fundamental resonant frequency is reached which is also swept across several times, the frequency finally being raised to 4000 c/s. The entire procedure takes about three minutes. Either automatic or manual frequency changing may be used. Specification 841,608 is referred to.

Title: Device for painting and drawing
IPC: A46B11/00
Filed: 1976-10-27
Abstract: The device consists of an elastic container (1) containing liquid paint and having an outlet duct (2) and a supply compartment (3). The supply compartment (3) is closed off by a perforated disc (4) which is covered on one side with a layer (6) of porous, permeable material. This device requires no closure to protect the liquid paint from drying out. This is prevented by the porous layer (6) which always remains soaked with liquid paint and forms a virtually hermetic seal. By exerting pressure on the container (1), the liquid paint can be removed either dropwise or evenly at the outlet duct (2) depending on the strength of the pressure. <IMAGE>
