Title: Paint applicator using electrostatic field - has spraying disc rotating at high speed and provided with annular spray dispersion rim
IPC: B05B5/04
Filed: 1975-12-26
Abstract: The applicator applies water based paint by means of an electrostatic field. The paint is fed (4) into the hub (1) of a disc (2) rotating between 8000 to 70,000 revolutions per minute, and projected forwards by the centrifugal force generated. The electrostatic field is used only to direct the spray. The disc has a dished cross section, the annular rim (3) being turned parallel to the drive sprindle axis (6) and having a knife edge (7). A baffle disc fits over the drive spindle, inside the dished portion, paint being fed into the chamber (5) formed behind it and distributed through an annular slit.

Title: Evaporation process for concentrating sodium hydroxide solns. - from electrolytic diaphragm cells
IPC: B01D1/26
Filed: 1976-01-09
Abstract: An evapn. process for concentrating sodium hydroxide soln from electrolytic diaphragm cells which decreased by 15-20% the amt. of steam needed by comparison with conventional triple effect evaporators. A prim. concn. step is done on the dil. liquor from the electrolytic cell in a simple evaporator (not working under vacuum) in which there is no formation of salts because of the operating conditions. The second stage of the process uses three evapn. effects operating under vacuum conditions. This effectively makes the plant into a quadruple effect evaporator although only three effects are working under vacuum. Calling the simple evaporator the first effect and the subsequent triple effect evaporator bodies numbers 2, 3 and 4 the feed soln. from the cells enters the first effect. The order of circulation of the NaOH soln. as it concentrates is 1, 3, 4, 2. Effects 2, 3, 4 operate at decreasing pressures in the order given. Steam fed to effect 1 produces vapour used to heat effect 2 and then similarly on to effects 3 and 4 in order to decreasing press. Solids are removed by a centrifuge in the concd. NaOH line between effects 4 and 2. The main advantage of the process is the attainment of the economies of a normal quadruple over a triple effect evaporator. If four effects were used operating all under vacuum the concn. could not be achieved without using mechanical vapour recompression between two evaporator bodies, thereby losing some of the operational cavings gained in a 4-effect system. The claimed process has no fouling of the heating section in the first effect.

Title: Retaining tube for removable partition panel - has lockable slide extended by spring from five to ten times length of slide path
Inventor: LACOUR ANDRE
IPC: E04B2/82
Filed: 1976-01-09
Abstract: A method of securing a partition or panel between a floor and a ceiling employs a tube which can be embedded inside the panel, with a spring inside which forces outwards a block (6) so that the tube holds the panel in position. Instead of directly contacting the roof and floor, packers may be inserted between the roof and floor and the blocks (6) concealed inside the panel. The bottom block may be secured by a bolt (10) passing through the block and tube. The spring is a good fit inside the tube to prevent the sping bending. The length of the spring is between five and ten times the travel of the block, and is at all times compressed. The bottom of the fixed block is shouldered.

Title: Self-locking nut with connected end segment - using shear neck which breaks when predetermined torque is reached
IPC: F16B31/02
Filed: 1977-09-20
Abstract: The self-locking unit is of the usual hexagonal form but has a deep and narrow circumferential groove (4) at approximately half-way along its thickness. This divides the nut into two segments (1, 2) connected by neck (3) of a predetermined torsional strength. The nut is tightened by applying a spanner to the outer end (2) which is sheared at the required torque. The outer end is still further tightened so that an additional tension is imposed on the bolt and at the same time the irregularities of the sheared surfaces lock the two parts together.

Title: Sorting of documents into mailbags - uses bag held open by elastic blade having slotted ends which engage edges of bag mouth
IPC: B65B67/04
Filed: 1977-09-21
Abstract: Sorting of documents into mail bags for despatch to different destinations is facilitated by insertion of an elastic member in the form of a blade into the opening of each bag. At each of its ends and on one of its edges the blade has a slot extending over a fraction of the width of the blade.
