Title: Colloidal compositions
Inventor: GRANT DAVID
IPC: B01J13/00
Filed: 1966-05-11
Abstract: 1,134,118. Acidic oxide sols. MONSANTO CHEMICALS Ltd. 12 April, 1967 [11 May, 1966], No. 20833/66. Heading C1A. An aqueous, colloidal acidic oxide concentrate, containing more than 50% by weight of the acidic oxide is prepared by subjecting an initial aquasol to increased gravitational force in a centrifuge. The product may take the form of a " solid-sol " which is easily dispersible in water or a water miscible organic liquid, such as acetone. For example, a silica aquasol containing 20 to 50% by weight of silica having a weight average particle diameter of 1000 to 2000 Š may be centrifuged under a force of 40,000 to 45,000 g. for periods of up to 1 hr. to give a " solid sol " containing 55 to 75% silica by weight. Increasing the initial particle size or the period of centrifugation increases the proportion of the silica originally present which is recovered in the solid sol. Other acidic oxides whose sols may be similarly treated include those of Al, Cr, Ti, V, W and Ge.

Title: Photosensitive compositions and their use in photomechanical printing
IPC: C08L71/02
Filed: 1961-06-12
Abstract: A photosensitive composition comprising 0.3 to 3.0 parts by weight of a polyethylene oxide, 1 part by weight of an A-stage resole phenolic resin, and 0.08 to 2 parts by weight of a photo-sensitive substance which yields free radicals on light exposure which react with the resole resin may be coated on a support and used to prepare a planographic printing plate.  The composition may contain an oxidizing agent.  The plate is exposed and developed with water to produce a continuous tone image which is ink receptive. Specified photo-sensitive compounds are iodoform, bromoform, halogenated paraffins, hydrogen halides, alkyl and alkylene iodides, fuchsin and rhodamine.  The resins are prepared by condensing phenolic compounds (e.g. phenol, cresol, resorcinol, xylenol, ethylphenol, butylphenol, isopropylmethoxyphenol, chlorophenol, hydroquinone and naphthol) with an aldehyde (e.g. formaldehyde, acetaldehyde, crotonaldehyde, furfural, acrolein, 1,3,5-trioxane and hexamethylene tetramine) or with a ketone (e.g. acetone). Oxidizing agents specified are ammonium, potassium or sodium persulphate, ammonium, potassium or sodium dichromate, ferric or stannic chloride, chromic oxide, cupric sulphate and mercuric chromate, acetate or oxalate.  Preparation of resoles.-A-stage phenolicaldehyde-resole resins are prepared by refluxing a mixture of phenol, (meta-cresol and resorcinol are also used) formalin or paraformaldehyde, water and sodium acetate trihydrate until the resin precipitates and the mixture is poured into water to complete the precipitation.  In one example sodium sulphate replaces the sodium acetate trihydrate as catalyst.

Title: Improvements in or relating to discharging apparatus of bins for powders and other flowable solid materials
IPC: B65G65/42
Filed: 1948-08-13
Abstract: 645,982. Endless-chain conveyers. REDLER, A. Aug. 13, 1948, Nos. 21437/48 and 6936/49. [Class 78 (i)] In apparatus for discharging the contents of bins of the kind described in Specification 159,236, [Class 78 (i)], the cross-bars of the conveyer are connected loosely at their ends to the chains so that they can move angularly backwards and forwards relatively to them. The end of each cross-bar 58, Fig. 1, is secured to an eye 60, Fig. 4, which surrounds loosely an inwardlydirected projection 59 on a pivot-pin of the chain. The chains 44a, 44b are advanced by ratchet pawls 34a, 34b, Fig. 2, which are pivoted on crank-pins 33a, 33b arranged at diametrically opposite positions at the ends of a shaft 30 driven through reduction gearing by a motor 26. Each pawl slidably engages the shaft 30 driven through reduction gearing by a motor 26. Each pawl slidably engages the lower edge 37 of a vertically adjustable member 38a. The false bottom 17 of the bin is made up of a number of sheet metal members 50 of inverted channel section which fit over tubes 52 mounted in the side walls 13 of the bin. The top member 50a is of greater width than the others and its front curved edge 54 guides the chains as they pass from the sprockets 49a, 49b on to the false bottom. These sprockets are fast on a freely rotatable shaft 47. At the beginning of the operative stroke of any pawl, only the upper run of the chain acted on moves. During the stroke, the slack between the sprockets 49a, 49b and the false bottom is taken up, so that later on both bottom runs of the chains are driven. During the stroke the upper run of the other chain is stationary. A depending member 56 of rubber or like flexible material prevents discharge of material at this point. In a modification alternate advancement of the upper runs of the chains is obtained by driving them from a pair of sprockets, each mounted eccentrically on a common driving shaft and disposed 180 degrees out of phase. In a further modification two series of cross-bars are connected to three chains which are advanced intermittently by three ratchet pawls oscillated by a common crank-shaft having three crank-pins with a mutual phase difference of 120 degrees. In still further modifications the chains may be moved throughout in unison. Specification 565,987 also is referred to.

Abstract: 1,055,657. Activation analysis. TOKYO SHIBAURA ELECTRIC CO. Ltd. May 25, 1964 [May 25, 1963], No.21583/64. Heading G1A. Apparatus for activation analysis comprises means for moving a sample to an irradiation station, and means receiving an electrical signal from a detector subjected said irradiation and producing an electrical signal which is the analogue of the radio-activity of a chemical monitor in similar circumstances to control movement of the sample to an activity measuring station and the initiation of activity measurement. A sample is loaded into a chamber 10 and transferred by air pressure from a blower 40 to an irradiation station 13 where its arrival is detected photoelectrically. A shutter 43 is opened to allow deuterons to fall on the target 45 where they produce neutrons with which the sample is irradiated. A neutron detector 49 generates signal indicative of the instantaneous neutron intensity and this is integrated at 50 to give a signal proportional at any instant to the radio-activity of a hypothetical reference body located in the irradiation beam. When the integrated signal reaches a predetermined level, contacts 53 are closed to close shutter 43 and actuate blower 40 to transfer the sample to an activity measuring station 15 where its arrival is detected photoelectrically and noted in a control pulse generator 48. When the output from unit 50 has fallen to a predetermined level, contacts 54 are closed to cause the control pulse generator 48 to start a scintillation counter 16 measuring the intensity on the activation of the sample. The counting continues for a preset time to produce an indication of the activity of the sample which is automatically compensated for variations in the irradiation intensity. Further samples may be tested at the same time by introducing them into chambers 20, 30 in parallel analysers. The integrator 50 may include a condenser/resistor circuit or a resistor/inductor circuit. X-rays, gamma rays or charged particles may be used in place of the neutrons for activation.

Simultaneously, the other service line connection is uncovered by the respective end 76, 77 of the slide to be connected to chamber 17 and reservoir. A second similar slide 18<SP>1</SP> is similarly actuated and operable.

Abstract: 685,628. Stuffing-box substitutes. HAPMAN, H. W. Aug. 23, 1949, No. 21859/49. Class 122(v) [Also in Group XXX] A device for engaging the edges of the flights of an endless flight conveyer in a sealing manner so as to enable solid material to be conveyed into or out of a chamber containing fluid comprises an inflatable tubular element having spaced outer and inner walls forming a chamber, said inner wall having a bore therethrough for the conveyer and being formed of elastic deformable material such that on the introduction of fluid pressure into said chamber, the inner wall is contracted inwardly into sealing engagement with the conveyer flights, and a reinforcing structure of round rods of resilient material embedded lengthwise in said inner wall outwardly of the inner surface thereof. In the embodiment shown in Figs. 1, 2, the sealing device 10 is inserted in a gap between portions 19, 20 of the conduit of a flight conveyer 11 comprising links 24, 25 and rubber or like flights 29 secured between pairs of plates 28. The links 24, 25 are spaced apart by resilient washers 30. The device 10 consists of a tubular member of rubber housed in a casing 12 and having inner and outer walls 36, 37 separated by an annular air space 38, the walls being joined at their ends by connecting walls 39, 42.
