Filed: 1966-06-10
Abstract: 1,153,286. Continuous discharge mixing apparatus. INSTITUT FUR LACKE UND FARBEN. 10 June, 1966, No. 25974/66. Heading B1C. [Also in Division G3] In a process for the continuous mixing of pigments and' extenders with liquid for the production of coating materials and printing colours, the input of one of the components of the mixture is automatically controlled in dependence on a radio-active measurement of the composition of the mixture after it leaves a flow-through type mixer. As shown, a gear pump 4 and a vibrator 6 respectively supply binder solution and pigment to a vessel 1 in which they are mixed by a stirrer 2. The composition of the mixture, which is withdrawn by a pump 9, is maintained at a desired value by a radiation gauge 8 the output of which is applied' through a magnetic amplifier 13 to control the speed of pump 4. The level in mixing vessel 1 is maintained between limits by a detector 14 adjusting the speed of pump 9 through a relay 15. The level in a buffer vessel 10 supplied from pump 9 is also maintained between predetermined limits by a detector 16 controlling vibrator 6.

Title: Improvements relating to electronic circuit arrangements
Inventor: CHENOWETH CHARLES PHILIP ERNES
IPC: H03M1/00
Filed: 1960-07-26
Abstract: 922,885. Non-contact-making relays. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 30, 1961 [July 26, 1960], No. 26010/60. Class 40 (9). [Also in Groups XXXVIII, XL (b)'and XL (c)] In a circuit, Fig. 1, for sampling the current in a line a switch W is closed to cause current to flow in the secondary winding of a transformer T in such a direction as to tend to increase the flux caused by the line current. The back E.M.F. induced by this current in the primary winding blocks a diode D1, thereby causing the line current to surge through a by-pass capacitor and as a result the secondary current rises sharply to such a level as to maintain the total flux in the transformer constant even though the primary current has been blocked. The level to which the secondary current rises is thus a measure of the line current that was flowing when the switch W was closed. In the main embodiment, Figs. 3 and 4, sixteen lines 1, 2 . . . 16 are sampled selectively under the control of eight transistors T1 . . . T8, the sampled current passing via a transistor TM to charge a capacitor C2 to a corresponding potential which is then digitized by counting clock pulses (see Group XXXVIII) until the capacitor is discharged to a reference level.

Title: Method of heating a coke-oven
IPC: C10B21/22
Filed: 1974-06-12
Abstract: 1468090 Coke ovens CARL STILL 12 June 1974 [13 June 1973] 26055/74 Heading F4B The heating flues of a coke oven are provided with air or gas nozzles 1, 2, Fig. 1, at different levels so that the heat can be applied at an upper or a lower level, each coking period being divided into a number of heating intervals, the heat being provided at an upper level during the first interval and at a lower level during the second interval. In the form of Fig. 1 gas can be supplied through nozzle 1 or nozzle 2 at different heights while air is supplied through openings 3. In the first interval, amounting to 60% of the coking time, gas is supplied only through the higher nozzle 2. In the second interval, 5%-20%, of the coking time, gas is supplied through the lower nozzle 1. In subsequent intervals nozzles 2 and 1 are used alternately, the supply of air being constant. In another form (Fig. 2, not shown) gas is supplied at a constant rate through a single low-level nozzle and air is supplied alternately through two nozzles at different levels. In a modification of the form of Fig. 1 having two gas nozzles at different levels, the air is supplied through a series of openings vertically spaced up the wall of the heating flue. A similar arrangement, Fig. 4, has a single gas inlet 10 and two series of air openings 11-14 and 15, 16. One series or the other is supplied with air, the heat being applied at a low or high level respectively. The coke chambers have a slight taper, being widest at the discharge end. The amount of heat applied at this end is increased to take account of the greater thickness of coal. Similarly where the gas take-off is asymmetrically placed more heat is applied to those parts of the oven distant from the take off.

Title: Improvements in and relating to means adapted to enable aircraft to pick up while inflight articles or persons
IPC: B64D1/22
Filed: 1934-09-13
Abstract: 444,245. Pneumatic guns. JOHNSON, D. C. CROOM-, Brenden, Ridley Road, Upper . Waringham, Surrey. Sept. 13, 1934, No. 26350. [Class 92 (ii)] [See also Group XXXII] In apparatus for enabling an aircraft while in motion to pick up an article such as a package or person, the article is propelled into engagefrom which the article 6 is adapted to be expelled into an aircraft receptacle 37 having an inturned lip 38. The gun, which may be of ment with receiving means associated with the aircraft at an overtaking speed suitably related to the speed of the aircraft by means such as a compressed-air gun or catapult set into operation by the passage of the aircraft. As shown in the Figure, a turntable 4 is mounted on a roller-track 3 in a circular pit 2 formed, for example, in the ground or on the roof of a building, and supports a compressed-air gun the breech or muzzle-loading type, comprises a chamber 8 into which compressed air is adapted to be injected through a pipe 13 and valve 14, and from which air initially is prevented from escaping by three double-seated differential valves 9, 18, 29. Flexible air pockets 23, 24 each in duplicate are provided in the table 4 and connected by pipes 22, 25 respectively with chambers closed by the larger valve faces of the valves 18, 29. In operation, the article 6 is placed in the barrel 5 as shown and the chamber 8 filled with compressed air. The landing-wheels of the aircraft first pass over the pockets 24 causing air to be ejected therefrom and to act on the valve 29 which opens and allows the air in the chamber 8 to commence escaping through a calibrated orifice 30. The wheels then pass over the pockets 23 and cause the air therein to act on the valve 17 which opens and permits the air to flow behind the larger valve surface of the valve 29 which also opens so that the main charge of air in the chamber 8 escapes into the space below the package 6 and ejects it. The force of ejection thus varies with the speed of the aircraft. The air pockets 23, 24 may be replaced by rubber tubing, electrical mechanism or mechanism operated by photo-electric cells. In a construction (not shown) embodying this last mechanism, three tubes are arranged in line on a turntable in the direction of flight of the aircraft, two of the tubes being vertical and one inclined. A photo-electric cell is arranged at the base of each tube, each cell being adapted to be illuminated in turn by a light fixed to the aircraft, the first two being adapted to measure the speed of the aircraft and the last one to fire the gun if the aircraft is at the correct height. The Provisional Specification refers also to a spring gun and to a gun using an explosive charge for propelling the article.

A mobile slewing jib crane 2 (Fig. 1), which can be coupled so that its front end is supported by the rear of a tractor vehicle, has retractable outriggers 18. In the form shown arms 16 (Fig. 3) carrying the outriggers are swung about hinges 14 on the vehicle by linkages 31, 28 operated by a ram 27 common to the two outriggers. Each outrigger has a flat or dished foot 22 adjustable vertically by a handle 25 and secured by pins 18A taking into sockets on the outrigger. The crane is supported trom the draught links of a tractor by a rear tongue 8 (Fig. 1) bolted to its chassis. A front axle 3 carrying wheels 5 can be removed. The controls 41 for the crane 1 and for the outriggers are carried on a stalk 42. The ram 27, and hydraulic drives for the crane, are operated either from the hydraulic system of the tractor, or from a pump 35 driven from the power take-off of the tractor, or from an air-cooled diesel engine mounted on the chassis of the crane. Three vertically-adjustable screwthreaded legs with ground-engaging feet may serve to support the crane chassis in the absence of the tractor. In an alternative construction the outriggers may be adjustably mounted on fixed projecting arms in place of the hinged arms 16. The feet 22 may be replaced by castors. The wheel axle 3 may be mounted further forward, and the crane chassis may be arranged to be towed by a lorry or by a small traction unit suitable for use on a building site. The motions of the crane may be driven mechanically instead of hydraulically. The Provisional Specification refers to Specification 896,411.

Title: Process for preparing urea-formaldehyde resin solid foams
IPC: C08J9/00
Filed: 1953-09-25
Abstract: A urea-formaldehyde resin foam is made by (1) emulsifying a low boiling organic water-insoluble liquid with an aqueous solution of a urea-formaldehyde resin having a viscosity of 200-10,000 centipoises in presence of an emulsifying agent; (2) vaporizing the liquid by raising the temperature or reducing the pressure, and (3) curing the resultant mixture made up of cells containing the said vapours by maintaining the mixture at a temperature above the boiling point of the organic liquid but below 115 DEG  C. in presence of an acidic cure catalyst and 10-35 per cent based on the weight of the resin of a polyethylene glycol having 3-50 oxyethylene groups per molecule. The mol. ratio of formaldehyde : urea in the resin is preferably 1.4 : 1 to 2.5 : 1.  Specified are: organic liquids-propane, ethyl chloride, a butene, butane, dichlorotetrafluoroethane and trichloromonofluoromethane; hardening catalysts-phosphoric acid, formic acid and sulphur dioxide; emulsifying agents-dioctyl esters of sodium sulfo-succinic acids, sulphates of fatty acid monoglycerides, fatty alcohol sulphates, sodium alky aryl sulphonates, sorbitan monolaurates and polyoxyethylene ethers of palmitic acid.  In an example, a mixture of an unpolymerized condensate of 5 mols of formaldehyde and 1 mol. of urea and polyethylene glycol was acidified to pH 2.2 with hydrochloric acid and allowed to stand overnight.  The solution was then adjusted to pH 8.0 with sodium hydroxide, urea was added to give a molar F/U ratio of 2.3 and the mixture heated to 50 DEG  C.  The pH was then adjusted to 5.2 with hydrochloric acid, the mixture heated to 85 DEG  C., then cooled and adjusted to pH 8.0 with sodium hydroxide.  Urea was then added to give a F/U ratio of 1.8, dibutyl phenyl phenol sodium sulphonate added and the mixture stored overnight.  The resultant resin solution was then cooled to - 5 DEG C., liquid butane added, and the mixture allowed to warm until expansion started.  Phosphoric acid was then added and the mixture poured into a tray and allowed to rise and set at room temperature.
