Title: Improvements relating to spraying apparatus
IPC: B05B12/00
Filed: 1960-03-19
Abstract: 981,551. Valves. W. E. STANTON. June 13, 1961 [March 19, 1960], No. 9804/60. Heading F2V. A number of primary valves 10, Fig. 2, in a spraying apparatus are actuated in a predetermined sequence by air conveyed through pipes 13 under the control of a master valve 16 comprising a block with as many through bores 15 as there are pipes 13 and hence valves 10. Above the upper face of the master valve block is a pressure-applying roller 20 with grooves 25 that register with the outer ends of the bores 15, which ends are fitted with resilient sealing rings. Between the roller and valve 16 is a membrane 27, preferably endless, of metal, e.g. aluminium, with ratchet teeth 28, Fig. 1, along one or both margins, which teeth are engaged by a pawl 29 operated by a pivoted piston and cylinder feed device 28 whereby the membrane 27 is moved across the valve 16. The membrane, which is supported on rollers 31, incorporates perforations 32, each valve 10 being actuated from a first to a second position whenever a perforation 32 is aligned with the corresponding bore 15. The ratchet and pawl may be replaced by a friction roller drive so providing a continuous instead of an intermittent traverse of the membrane; the rollers may be driven by a ratchet-and-pawl device. A pad may be substituted for the pressure roller and the membrane may be made of a synthetic resin, e.g. nylon or P.V.C. The feed movement of the membrane may be related to the function or stage reached in the programme of the devices to be controlled; in one instance the spraying apparatus includes limit valves which control operation of the feed device. Specification 672,969 is referred to.

Patent GB-614309-A (GB)
Title: Improvements relating to fractionation applied to petroleum and other hydrocarbon feedstocks
IPC: B01D3/08
Filed: 1945-04-19
Abstract: Hydrocarbons boiling within a range of 30 DEG  F. are economically separated by subjecting the mixture to fractional distillation in a centrifugal fractionator which is heated by vapours withdrawn from the fractionator and compressed.  The pressure of the vapours withdrawn is preferably raised to a value at which the temperature of the compressed vapour is not less than 5 DEG  F. above the temperature of the liquid leaving the stripping section of the fractionator.  The process is particularly applicable to the separation of pure paraffin or aromatic hydrocarbons from close-boiling fractions, or of pure olefinic hydrocarbons from fractions of cracked spirit.  The vapours of hexane, heptane and octane are particularly suitable for compression.  The compression required may be obtained by injection, along with the reflux, of an immiscible liquid of low vapour pressure at the centre of the centrifugal fractionator.  In an example, a mixture of normal and iso-butane together with small quantities of propane and pentane was fractionated in a centrifugal fractionator having substantially no pressure drop and operating at 73.7 lbs. per square inch (absolute). Isobutane at 100 DEG  F. was taken off overhead, compressed to 109 lbs. per square inch (128 DEG  F.) in an electrical compressor, and passed to the reboiler where normal butane was boiling at 123 DEG  F. Specifications 590,554 and 600,551 are referred to.

Title: Improvements in or relating to rigid, light-weight board material
IPC: D21H15/06
Filed: 1963-03-13
Abstract: 1,010,384. Paper. B. SAMWAYS. March 13, 1964 [March 13,1963], No. 9932/63. Heading D2B. [Also in Division B5] A method of manufacturing a rigid lightweight board material comprises advancing a series of separate strips 4 of flexible sheet material, the strips being of equal and uniform width, set on edge and having an undulating zig-zag or wavy configuration in edge view, and securing the strips by their edges between a pair of spaced sheets 13, 15 of flexible material. In a particular embodiment, a sheet 1 of kraft paper is slit into a number of strips 4 by a bank of knives 5. The strips are fed forward positively by rollers 3 to a pair of spaced combs 6, 7 having vertically disposed slots 8,9 thus turning the strips through 90 degrees. The comb 6 is stationary,but the comb 7 reciprocates transversely to the path of travel of the strips to vary the point of feed of the strips between spaced rolls 11, 12 where sheets 13,15, of kraft paper previously coated with adhesive from applicator rolls 14,16 respectively are applied to the upper and lower edges respectively of the strips 4. The sheets 13, 15 may be held against the edges of the strips by further rollers or other means not shown until the adhesive is set, which may be accelerated by the application of hot air or radiant heat. A multi layer board may be made by applying a further set of strips and a further sheet of material in a similar manner (Fig. 7, not shown). Alternatively the edges of strips may be coated with adhesive. The sheets may be applied one at a time, instead of simultaneously, and the rollers 11,12 may be replaced by belts (see Fig. 9, not shown). To aid feeding of the strips, the combs 7 may be reciprocated in a direction parallel to that of travel of the strips, and the slots of the combs may be designed so they grip the strips while the comb is moved towards the sheets but release them as the comb moves away. The strips may be secured to the sheets so the peak of one strip reaches into the hollow of neighbouring strips, or the peaks of each strip may make contact with neighbouring strips to form closed pockets. Suitable flexible sheet material include paper and cardboard. A suitable adhesive is a polyvinyl acetate emulsion.

Title: Process for preparing dried fruit with intensive flavour, low water content, porous structure and crisp consistence, particularly from apple fruits
Inventor: BERKI FERENC
IPC: A23L19/00
Filed: 1985-11-26
Abstract: Crunchy dried fruit of low moisture content, of porous texture and intensive flavour is prepared by the following method. Apples or similar fruits are cleaned, cut into suitable pieces and are treated for the preservation of their colour with an alkali sulphite or citric acid and/or ascorbic acid soln. followed by immersion, at atmospheric or reduced 10-100 mbar pressure, into a soln. of starch and/or of a plant hydrocolloid, and/or of culinary gelatine. The fruit is pre-dried at 50-120 deg.C by convective heat using an air current of 1-5 m/sec. to achieve a 50-70% weight loss while drying a thin flexible surface film develops. This impedes the diffusion of moisture. The moisture content of the fruit is reduced further to 2-5% by a current (0.1-1 m/s) of warm air or by contact drying or by infrared radiation. The process is carried out so that the fruit should get puffed with the development of a porous structure. The prod. is stored in sealed airtight packages.
