Title: Fatty acids prepn
IPC: C11B13/02
Filed: 1969-10-06
Abstract: Fatty acids, synthetic fatty acids, resinous naphthenic acids, or their mixtures are prepd. by treatment of aqs. solns. of the Na salts of these organic acids with a a mineral acid while heating. Before the treatment, an aqs. soln. (I) contnt. 0.1-2% mineral acid and 2-3% of its Na salt is prepd. in the reaction volume. The aqs. soln. of the Na salt of the organic acid is then introduced from below, while simultaneously introducing the mineral acid in counter-current to the salt solns. The introductions are effected at such a rate that the amount of mineral acid in the reaction medium is maintained at 0.1-2% and the treatment temp. is 85-95 degrees C. The process gives improved yield and purity of acids, with reduced consumption of mineral acid.

Title: Measurement of clear area on photo negatives - blinds used to give equal light drop to that of negative
IPC: H05K3/10
Filed: 1973-03-19
Abstract: An instrument to measure the transparent area of a photographic negative, particularly those to be used for laying out printed circuits, uses a null method. The negative is placed on a uniformly lit screen and the edges masked. The light passing through the clear area is picked up by a photo-cell and a meter indication noted. The negative is removed, leaving the masks in place and a blind, which may be two, symmetrically placed is drawn across to partially obscure the light until the same reading is obtained. Suitable scales on the blind controls determine the equivalent area of the negative.

Title: Measuring reactivity eg polymerisation speed of resin - using viscometer to detect phase changes
IPC: G01N33/44
Filed: 1974-10-08
Abstract: To measure the reactivity (i.e. polymerisation or polycondensation speed) of a resin a sample of the rsin is maintained in a container at a temp. above its melting point and the changes in viscosity of the resin or changes of another property dependent on viscosity are continually measured by a viscometer and plotted. The inflexions in the resulting plot of e.g. viscosity against time show the points at which there is a change in the phase (i.e. physical state) of the resin occur. The reactivity of a resin at a given temp. can be accurately determined without relying on subjective observations of testing personnel.

Title: Floc or fibre deposition apparatus - for coating articles using a composite AC/DC field
IPC: B05C19/02
Filed: 1975-03-11
Abstract: In an appts. for coating articles with powdered or granular particles, e.g. fibres or flocs, comprising in known manner an insulating support for the particles, at least one counter electrode between the insulating support and the article to be coated and a second electrode situated on the side of the support furthest from the article while a third electrode is placed in the zone of the article either in front of or behind this or formed by the article itself, the various electrodes creating (a) an a.c. field across the insulating support, for raising the particles from this and imparting to them an eddying motion and (b) a d.c. field for accelerating the particles so detached from the support in the direction of the article to be covered, the novel feature whereby (c) the electrode situated in the zone of the article is connected to earth by an electrical conductor (d) the counter electrode and the electrode facing it on the other side of the insulating support are each connected by conductors to a source of supply of an a.c. potential superimposed on a d.c. potential different from earth potential, while a protective resistance is mounted on the conductor connecting each electrode to the potential source. The coating equipment has fewer components than apparatus normally used and enables a wide range of articles to be floc-, fibre- or powder-coated. Since no stram of fluidising air is necessary the risk of fire from distruptive discharges is much less and is reduced still further by the provision of the protective resistance.

Title: System for transferring hot air to floor from CEILING AREA - using venturis to draw in air from heaters
IPC: F24D5/02
Filed: 1975-04-01

Title: Reinforced concrete floor construction - with counter braces, and trimmers passed along duct faces without breaking them
IPC: E04B5/48
Filed: 1975-08-12
Abstract: The reinforced concrete floor has gaps in between the joists, and concrete is poured over the joists, gaps, and shuttering. Ducts are also formed in the floor, the transverse ones being able to pass through the joists without affecting the areas of compressed concrete and the stressed steel, while the longitudinal ducts are parallel to the joists. The counter-braces and trimmer beams which carry over the loading on one joist to adjacent joists pass along one face of the longitudinal ducts without breaking into them. The loads carried over by a trimmer beam are reduced and distributed among adjacent joists by means of at least one counter-brace. The transverse ducts which run close to the joist supports pass under the braced steel bars focused in a reinforced concrete tie located in the axis of each joist.

Title: Power transmitting ball joint - has overlapping sleeve sections formed into spigots which mesh with each other transmitting high power through angled shafts
IPC: F16D3/18
Filed: 1975-09-05
Abstract: Each shaft of the ball joint has a sleeve fixed to its end. The portions of the sleeves which overlap the ends of the shafts are formed into four spigots or dogs, which mesh with each other. One set of dogs is shaped internally into a part sphere.
