Title: Immersed aerated bubble tube for purifying water in tanks and pools - by scum flotation, esp. for fish farming tanks
Inventor: BARNABE GILBERT
IPC: A01K63/04
Filed: 1976-09-08
Abstract: The equipment has a vertical, cylindrical column with its lower end immersed in the water and provided with a discharge outlet. The upper end of the colum leads into a chimney extending above the surface of the water. A branch pipe enters the column below the surface to deliver into the column recirculated water drawn from the tank. The branch pipe now has an in-line venturi with provision to draw in air at the throat section. Inside the column, an emulsion of water and air bubbles forms a rising scum which is evacuated via the chimney, the purified water returning to the tank through the column base discharge outlet. The branch pipe enters the column tangentially below column water level. The discharge outlet pref. leaves the column tangentially oriented for intake fro the swirl created by the branch pipe. Greatly increased vol. of scum compared with existing systems. This has the effect of substantially reducing the concn. in the water or iron, copper, zinc, nitrogen, phosphorus, oreanic carbon and suspended impurities. Aeration of the water is simultaneously enhanced. In a seawater fish farming tank, a 95% recirculation is possible during the winter.

Title: High inherent viscosity polyamide prepn. - from para-phenylenediamine and terephthaloyl chloride using n-methyl-pyrrolidone solvent
Inventor: ROCHINA VINCENT
IPC: C08G69/28
Filed: 1977-04-27
Abstract: Continuous prepn. of a polyamide of formula (I): (in which 50-100% of the R groups are p-phenylene groups and 0-50 wt.% are n-butylene groups), comprises reacting molten terephthaloyl chloride (TPC) and opt. adipoyl chloride with a soln. of p-phenylenediamine and/or 4,4'-diaminoadipanilide and opt. of a prepolymer of the acid chloride and diamine, in a mixt. of N-methylpyrrolidone-2-(NMP) and CaCl2. The polymer having an inherent viscosity >=3, measured on a soln. in 100% sulphuric acid at 25 degrees C at a concn. of 0.5g polymer in 100 ml solvent. The reaction conditions are such that the acid chloride and the diamine are in stoichiometric amts. The soln. of diamine is homogeneous. The mole ratio between the CaCl2 and the no. of units (I) is >=1 pref. >=1.15 and the relative amts. of reactants and solvents is such that at the end of the reaction the compsn. contains >=5 wt.% polyamide wrt NMP. Compared to prior art, the process is non-toxic. NMP is also more stable to hydrolysis and thermolysis than hexamethylphosphotriamide, resulting in reduced losses during recovery. Also only small amts. of CaCl2 are used.

Title: Overhead electric cable tensioner - is manually operated and prevents cable twisting and over-tensioning during adjustment using series of slots for hooks
IPC: H02G7/02
Filed: 1977-05-05
Abstract: A tensioner is for overhead power or communications cables, tension being applied without any tendency to put a twist on the cable. The system also avoids exerting too much tension on the cable. The tensioner (2) is approximately rectangular in elevation and plan and has a laminated construction. Attachment to the supporting pole or mast is via a hole (3) at one end, most of the remaining length having shaped equally spaced slots (5) angled towards the support point. Tension is altered manually and hence minimises the risk of overtensioning and is achieved by dropping the cable terminal hook (18) into the required slot. A guard (10), in the form of a stiff wire loop, is included to provide protection against any tendancy for the cable to jump out.

Title: Central heating system controlled by outside conditions - uses monitoring and comparison system to regulate fuel supply
IPC: F24F11/00
Filed: 1977-07-11
Abstract: A central heating system operated to adapt to the time of day and/or the time of year, alters the predetermined time intervals. After a second set of predetermined time intervals, the heating is cut off and if a predetermined support temperature differs from the normal temperature the ambient temperature is controlled by comparison. During the second time intervals, the heating is reversed so that the normal temperature is reached as quickly as possible. In cold external conditions, the support temperature is raised, and is controlled from two fixed points. For outside temperatures which require the maximum heating up during the first time intervals, the support temperature is adjusted to the estimated normal temperature.

Title: Oxalate conversion coating low alloy steels - with soln. contg. oxalate, tungstate and opt. borate and chloride ions
IPC: C10N50/08
Filed: 1977-07-13
Abstract: A C-steel contg. 10%C or an alloy steel, excepting stainless steel, contg. 10%Cr and 2%Mo is surface treated by immersing in an aq. soln. contg. an oxalate ion and a tungstate ion and opt. a borate ion, the amt. of the latter being 10% of that of the oxalate ion, and opt. 0.5-3.0g/l of Cl-. The surface coating provides a lubricating layer during cold working. It is thought that dissolved Fe reacts with the tungstate to give a hard and thick coating which adheres well to the substrate. Consequently the Fe concn. in the soln. does not increase and the amt. of Fe slime formed is reduced leading to increased life and stability of the soln. Borate ions retard the reaction and in combination with tungstate ions give a coherent, hard coating.
