Title: Improvements in or relating to manifolding books
IPC: B41L1/32
Filed: 1933-07-15
Abstract: 401,623. Manifolding books. BALLANTYNE, W. H., 111, Hatton Garden, London.-(Appleford Paper Products, Ltd.; 78, Stirton Street, Hamilton, Ontario, Canada.) July 15, 1933, No. 20068. [Class 16.] In a manifolding arrangement comprising interleaved record leaves and transfer leaves forming a series of manifolding units, a series of detachable record leaves is provided, and a continuous runner or web extending through all the units and folded in a zig-zag manner to form a series of permanently connected record and transfer leaves, one of each of the latter leaves being positioned in each manifolding unit. A paper web or runner A, Fig. 1, folded zig-zag to form record leaves 1, 2, and a paper web or runner B, Fig. 2, folded zig-zag to form leaves 3, 4 which are carbonized on their undersurfaces only, are interleaved and closed together, as shown in Fig. 5, so that a record made on the top record leaf 1 is transferred to the back of the leaf 4 by the overlying transfer leaf 3, while the leaf 4 in turn transfers the record to the underlying record leaf 2. In a modification the runner B has translucent leaves 3, and the leaves 4 are carbonized on both sides, so that the leaves 3 bear the record instead of the leaves 4. Clean margins 9 arc preferably provided at the ends of the carbonized leaves of either form of runner B. Lines of weakness 10 are provided in the runner A and, if desired, in the runner B to facilitate separation of the leaves. In a further modification the continuous record web or runner A is dispensed with, and the record leaves 1, 2 are formed in separate sets each gummed by one end to the runner B so as to fold in therewith to bring the record and transfer surfaces into the same relationship as described above. Each set of leaves 1, 2 may be detached from the runner B along a line of weakness. If desired, each attached set may include more than two leaves. A cover for the manifolding arrangement comprises a base or back 5, Fig. 5, on which the arrangement rests, two side flaps 6 adapted to fold over some of the lower leaves, a front cover 7, and a stop sheet 8. In use, the stop sheet 8 is placed beneath the first set of leaves 1-4, and when a record is made the leaves 1, 2 are detached from the runner A, or from the runner B as the case may be, and the folded leaves 3, 4 of the runner B are then turned back over the front cover 7, one of them bearing a record. The next set of four leaves is then brought over the stop sheet 8 ready for the next entry. When all the record leaves 1, 2 have been used and removed, there remains a web formed of transfer leaves alternated with record leaves carrying copies of all the records made on the leaves 1, 2.

Title: Improvements in or relating to apparatus for measuring and recording the progressive separation of the constituents of a liquid mixture
IPC: G01N15/05
Filed: 1954-07-09
Abstract: 756,625. Photo-electric control systems. WYSS, F. July 9, 1954 [July 9, 1953], No. 20177/54. Calss 40 (3). In apparatus for determining how far the separation of a liquid mixture (in a transparent container) has progressed a photo-electric scanner progresses axially along each container in sequence detects the surface of separation and at the same time marks a recorder associated with each container. As shown each container 1 has associated with it a recording drum driven at constant speed. The scanning arrangement comprises a light source producing a horizontal beam through a slot 7, lens 8 and photo-electric cell 9. The scanning elements together with a marking device 14 are all mounted on a common frame which moves axially along each container. The marking device comprises a pencil 10 which is recovered from contact with recording drum 20 when an electromagnet 15 is energized. This occurs only when the cell receives light passing through the surface of separation of the constituents. In an alternative arrangement the pencil may mark when the electromagnet is energized. The scanning assembly including the marking device may be operated by an electric timing device which scans one container marking the appropriate recording drum accordingly and then moves to the next container and the associated recording drum finally returning to the initial position. Instead of the arrangement described each container may have its own light source which is energized when a movable photo-sensitive device scans the container. Alternatively, each container may also have its own photo-sensitive device.

Abstract: 378,618. Washing-machines. JENNER, C. E., Aldwick, Beresford Road, Cheam, Surrey, and CORTEEN, J., The Homestead, Oakhill Road, Putney, London. July 14, 1931, No. 20230. [Class 138 (ii).] A washing-machine comprises a curved table 20, Fig. 1, carried by a support 21 which is pivoted by a universal joint 23 to an adjustable support 36 in the bottom of a tank 2. A brush 8 which may be made of bristles or transverse rubber strips is oscillated over the work on the table 20 about the vertical axis 8a, Fig. 7, of the arm 7, which carries the brush, by means of a link 9, Fig. 3, and eccentric 10 on a shaft 11 driven from a motor 13, Fig. 1. The motor also drives a pump 14 which draws liquid from the tank 2 through a strainer 15 and passes it through a pipe 17 and flexible coupling 18, Fig. 7, into the hollow back of the brush. The surface of the work-table is covered with resilient material and the motion of the table and support 21 is limited by a frame 24, Fig. 3. A guard 26, Fig. 7, is secured over the arm 7 and is provided with a lid 28 to give access to the head 29 of the bolt by which the brush is secured to the arm 7. Rotation of the brush on the bolt is prevented by the engagement of a flat 34 on the brush with a lug 35 on the arm. To compensate for the arcuate motion of the arm 7 the outer end of the link 9 is located in a bifurcated lug 47 which carries a pin 50 passed through a rubber ring 48 in a collar 49 formed at the outer end of the link.

Title: Prevention of corrosion during the distillation of hydrocarbons
Inventor: MILNER DAVID WILLIAM
IPC: C10G7/10
Filed: 1953-07-21
Abstract: Benzoic acid is obtained by subjecting naphthas which contain benzonitrile to steam distillation in the presence of a small proportion of sodium hydroxide, added as a fine dispersion of normally-solid, hydrated sodium hydroxide (52 to 84 per cent NaOH) in a liquid, such as xylene, which is a non-solvent for the alkali but which is miscible with the naphtha.  Benzoic acid is isolated from the still-residue by aqueous extraction and acidification. In an example, a hydrocarbon fraction (100 parts) containing 3.4 per cent benzonitrile was mixed with sodium hydroxide (2.9 parts on a dry basis) dispersed in xylene.  The mixture was heated at 155 DEG  C. for 3 hours, and steam was passed through at a rate of 60 parts per hour.  The naphtha portion of the distillate was returned continuously to the still until the evolution of ammonia had almost ceased, and then the naphtha was allowed to distil until 80 per cent of the charge had been removed.  The residue was then washed with water; the aqueous extract was separated, decolorized with animal charcoal, and finally acidified to precipitate the benzoic acid.  The prevention of corrosion during the distillation of acid-washed naphthas is also described (see Group III).ALSO:In order to prevent corrosion of the still and the condenser during the distillation of acid-washed naphthas, the distillation is conducted in the presence of a small proportion of sodium hydroxide, added as a fine dispersion of normally-solid, hydrated sodium hydroxide (52 to 84 per cent. NaOH) in a liquid, such as xylene, which is a non-solvent for the alkali but which is miscible with the acid-washed naphtha.  The dispersion is made by heating the alkali with the dispersing liquid until the alkali is molten, and then subjecting the mixture to high-speed agitation or to ultrasonic treatment.  A wetting agent may be added.  In an example, 267 parts of sodium hydroxide (75 per cent. NaOH; M.P. 75 DEG  C.) were heated to 85 DEG  C. in a steel vessel with 126 parts of xylene.  Oleic acid (3 parts) and a synthetic wetting agent (1.5 parts) were added; and the mixture was subjected to high-speed agitation for 10 minutes.  The mixture was then cooled; and additional xylene was stirred in to make a dispersion having 50 grm. of sodium hydroxide per 100 mls. of dispersion.  The dispersion was then used in the distillation of acid-washed solvent naphtha, in such an amount that there were 0.1 grm. of sodium hydroxide per 100 mls. of charge.  The distillate was collected in four fractions, each of which was found to be either neutral, or alkaline (due to ammonia).  The preparation of benzoic acid from naphthas which contain benzonitrile is also described (see Group IV (b)).

Title: Improvements in or relating to the manufacture of vegetable oil emulsions
IPC: C09K23/00
Filed: 1947-07-28
Abstract: A vegetable oil having an acid value between 1.0 and 2.5 is dispersed in an aqueous liquid containing sufficient of an alkaline reacting substance to neutralize the free acid.  The said alkaline reacting substances are sodium and potassium hydroxides and carbonates, sodium borate and sodium phosphate.  As preservative sodium benzoate is added.  In an example: castor oil has ricinoleic acid added thereto to increase acid value to 1.8 and is heated to 100 DEG  C.  An aqueous solution of sodium borate and benzoate also at 100 DEG  C. is poured into the oil.  Mixture heated for 2 minutes to 100 DEG  C and water added to replace that lost by evaporation.  Mixture poured into heated flask (above 60 DEG  C.) and agitated till temperature falls to 15 DEG  C., and then re-emulsified after 24 hours to give an emulsion of increased stability.  Oleic acid may replace ricinoleic, and the mixture may be agitated in a rotary emulsifier, colloid mill or piston emulsifier.  Saccharine, rum extract, colouring matters or neutral substances or other anionic emulsifying agents and protective colloids (methyl cellulose, bentonite) can be added.

Title: A process for the oxidative conversion of organic compounds
IPC: C07C45/34
Filed: 1962-05-28
Abstract: a ,b -Unsaturated aldehydes are prepared by passing an a -olefin in admixture with a molecular oxygen-containing gas at a temperature between 250 DEG  and 650 DEG  C. through a fixed catalyst bed comprising an oxygen-containing compound of molybdenum and, at least initially, a copper-containing catalyst, the latter constituting the initial part of said catalyst bed. Specified olefins are propylene and isobutylene. The molybdenum-containing catalyst may be an oxide, a salt, a heteropoly acid or a metallate and may also contain one or more other metals, e.g. Pb, Fe, As, Te, Bi, V, Cr, Mn, Co, Ni and In, which may be present in the form of oxides, phosphates or heteropoly acids.  The copper catalyst consists essentially of copper and/or one or more oxides of copper and may contain other metals, e.g. Fe, Co, Ni, Cd, Pb, Ag, Te, Mn and Zn, present in metallic or oxidized form or in combination with phosphorus.  In one embodiment of the invention the oxidation is initiated by passing the reactants over the copper-containing and the molybdenum-containing catalyst and the feed to the reactor is then modified to alter the behaviour of the copper-containing catalyst.  This variation may constitute promotion, deactivation or complete poisoning of the copper-containing catalyst by means of a change in the relative proportions of the components of the feed and/or the addition of new components.  Examples are given. Specification 798,564 is referred to.
