Title: Liquid sepn. by distillation with auxiliary agent - specif. useful in stripping impurities from oils
IPC: C11B3/14
Filed: 1975-06-23
Abstract: Impurities from oils are stripped by distn. with an auxiliary agent by mixing the auxiliary agent, at a high temp. and under a press. higher than that at which it would boil, with the prod. to be purified, which is substantially at the same temp. and press. and then submitting the mixt. to a very much lower press. so that spontaneous sepn. occurs. The press. to achieve mutual molecular soln. is typically about 50 atmospheres and the temp. about 220 degrees C. The press. is reduced to about 1 to 30 torr to achieve sepn. The auxiliary agent is typically water or superheated steam. The appts. for carrying out the process incorporates a mixer an expansion chamber and a separator together with pipes, pumps and heat exchangers. Method is specif. used for purifying oils which may be mineral oils or oils to be used in food prods. The sepn. is better than that achieved by existing methods in which the auxiliary agent is injected in the gaseous phase because of the achievement of complete mutual molecular soln. between the auxiliary agent and the prod. to be treated, ensuring intimate contact. The prod. is exposed to high temp. for only a short time. The appts. can be smaller than existing appts. and contains only a small quantity of prod. allowing rapid changing of product if necessary.

Title: Automatic chemical analysis by titration - with rate of reagent generation or addn. controlled according to defined law
IPC: G01N31/16
Filed: 1976-03-12
Abstract: Chemical analysis is effected by automatic titration of a soln., in which an electrical potential Em, coming from e.g. indicator and reference electrodes in the soln., is compared to a defined potential Ec. The improvement is that the potential Ec is modified during the titration according to a programme of specified duration until it has reached a final value Ec(fin). The modification is carried out either by successive steps or continuously. The number, the duration and the amplitude of the steps, or the law governing the continuous change, are fixed in advance or chosen by the operator according to the analysis being carried out. The difference Em-Ec is used to control the rate U of generation or addn. of the titrating species. The rate is further dependent on the value of the derivative dEm/dt, where t-time, and the difference between Em(or Ec) and a comparison potential E(comp). The relation is of the form U = k(Em-Ec)x(Em-E comp)y(dEm/dt)z + m. The values k, Ec, x, Ecomp, y,z,m can be fixed in advance or controllable by the operator, it being specified that x,y are not negative, z is not positive, x,y, z are not O simultaneously, m is not negative, k is not zero. Method is suitable for large and small quantities of liq and ensures that the quantity of titrating species cannot exceed that defined by the stoichiometry of the reaction. The analytical programme, e.g. over 24 hours, can be chosen in advance, and the precision is constant.

Title: Glass panes travelling on horizontal conveyors - and swivelled by clamping one side of pane on an air cushion table
IPC: B65G51/03
Filed: 1976-04-23
Abstract: Device is for swivelling a glass pane which is moving horizontally and in a straight path on an air cushion table. The pane is clamped near one edge by a pair of pads which are free to rotate; and the kinetic energy in the pane causes it to swing in a horizontal plane by e.g. 90 degrees. One edge of the pane then arrives between a conveyor belt and a row of spring loaded rollers so the movement of the pane continues either along the same path or along another path, e.g. at 90 degrees to the initial path. The movement of the pane pref. triggers limit switches to actuate the clamping pads and the conveyor belt so they come into contact with the pane. A damped aligning rail can be used when a pane is being transferred to a conveyor located at 90 degrees to the initial path of the pane. Used for a row of panes travelling rapidly along a conveyor belt. The panes can be turned through e.g. 90 degrees and then (a) travel along the same path; or (b) travel along a new path.
