Title: Gas/solid entrainment contacter - comprising fluidizing and pneumatic suspension suitable for drying powders
IPC: F26B3/08
Filed: 1971-05-27
Abstract: Solid introduced at one end of a tunnel is ventilated e.g. by hot gas, split into three independently controllable streams; the first stream aids transfer of solid e.g. to a rotary outlet valve at other end of tunnel; the second, being introduced through a grille at bottom of chamber induces fluidization; the third pref. passing around hollow walls surrounding tunnel, is introduced through slits at sides of base, and serves to entrain fine or dried solid, and maintain it in turbulent circulation. The apparatus is esp. for drying solids and can deal with powders of diverse particle size producing a uniformly dried product, but may also be applied for gas/solid reactions, humidification etc. By using e.g. a cyclone precipitator, in outlet gas stream, powders may be classified into fine and coarse fractions.

Title: Brake control system to assist cornering - has steering wheel actuated valve applying brakes to two wheels one side
IPC: B60T8/24
Filed: 1974-05-15

When the steering wheel is turned, a toothed sector is swung so as to operate a rack and pinion drive which moves a valve slider arm so that a piston moves sideways from its central position. In the central position, hydraulic fluid travels through a delivery line, into a valve chamber round the middle of the piston, and out through a delivery line to operate all the brakes. In the sideways position, the fluid travels from the chamber around another part of the piston, and out through an end discharge part, so that the brakes on that side are applied, actuated by the brake pedal.

Title: Twin masted ships derrick - with single boom and two slings for improved access to load suspended from above
IPC: B63B27/04
Filed: 1974-09-12

Title: Bonded glass fibre mats mfr. - pre-treating uncut fibres with cationic surfactant, avoiding viscosity builder in fibre slurry and allowing continuous operation
IPC: C03C25/10
Filed: 1974-11-13
Abstract: In prodn. of bonded glass-fibre mats (a) the glass fibres are treated with an aq. soln. of 0.02-2.5 (0.1-1.5) wt. % of a cationic surfactant with mol. wt. >150 and with cationic properties provided by an organic or salt unit contg. N, S P or Sb, (b) the treated fibres are cut into lengths, (c) the cut fibres are slurried in a soln. of 0.001-0.05 wt. % of a cationic surfactant, (d) the fibres are formed into a fabric or felt and treated with a binder and (e) the binder is hardened. The use of a viscosity builder in the slurry is avoided, or the amt. is lower. The concn. of the surfactant in the slurry is less. The process can be carried out continuously in a closed system, since insol. residues are not formed in the slurry; the aq. phase from the slurry can therefore be recycled.

Title: Hydrogen fluoride prodn. - by reacting metal fluoride, esp. fluorspar, with sulphuric acid vapour in presence of water vapour
IPC: C01B7/19
Filed: 1975-02-25
Abstract: Prodn. of HF by reaction between a metal fluoride, esp. CaF2, with H2SO4 is improved in that the metal fluoride and a carrier gas are preliminarily heated to a temp. above the boiling point of the sulphuric acid used so that the latter participates in the reaction in the vapour form and there is no liquid phase. The process is pref. carried out in a fluidised bed of fluorspar at 330-370 degrees C; steam added to the carrier gas for the sulphuric acid vapour is a molar ratio of 3:1 to 1:3 w.r.t. H2SO4; the carrier gas is pref. air. Coalescence of the resulting CaSO4 particles or their deposition on the walls of the reactor is prevented, and free-flowing CaSO4 powder is produced. Corrosion of the appts. is suppressed because of the absence of any liquid phase. Prodn. of fluorosulphonic acid is prevented by introduction of steam.
