Title: Elastic wave coordinate meter - detects delay from surface point to detectors on coordinate axes
IPC: G06F3/043
Filed: 1974-03-19
Abstract: The meter supplies the coordinates of a point on a surface with respect to two axes. A movable transmitter (3) placed in the neighbourhood of the point (4) emits elastic waves in the air from an initial instant in time. Detectors are placed on the first of the two coordinate axes and detectors are placed on the second of the two coordinate axes. These detectors receive the elastic waves which are delayed with respect to the initial instant as a function of the position of the emitter. A processing system connected to the transmitter and detectors supplies, from the delay times, the coordinalis of the point.

Title: Resistance welding steel grids for concrete reinforcement - using short second heating cycle to ensure ductile welds
IPC: B21F27/10
Filed: 1974-11-12
Abstract: Metal grids are mfd. from longitudinal and transverse bars, esp. in naturally hard steels. Immediately after resistance welding and while the bars are still under press., a further heating cycle is applied which is sufficient to retard the cooling speed below the critical quenching speed. The extra heat is pref. applied by passing a low current across the weld for a pre-determined time using the welding electrodes, or auxiliary electrodes on the bar with the larger cross-section. The welding and heating phases can be partly superimposed on each other and can be electronically controlled to a pre-arranged programme. The process avoids brittleness or cracks in the region of the weld, due to the presence of a high carbon content of the alloying elements, combined with rapid cooling after welding.

Title: Purification and settlement plant for effluents - from individual and collective sewage systems
IPC: C02F3/12
Filed: 1975-05-28
Abstract: The plant is combined with a tank for coarse screening and grit removal and comprises a reservoir sepd. into two compartments (A, B). In the larger (A) the suspended matter and sludge is oxidised and digested while compartment (B) acts as a settlement tank. The two compartments are isolated from each other and communication is only possible by a passage between the base and the folded end of the sepg. wall. Diffusers admit compressed air, from a pipe to create turbulence in the water to be treated to facilitate oxidn. of the suspended matter and accelerate its degeneration and degradation. The tank has a pipe at its base provided with radial orifices. Air is injected to keep the organic matter in suspension before transfer to compartment (A) while a grid over the outlet retains any suspended mineral matter. The plant is highly efficient both for small and large scale installations. The size of the tank can be adjusted to the vol. to be treated and the number of air diffusers increased in proportion.

Title: Isomerising alpha, beta unsaturated aldehydes - as to trans or vice versa by heating with acid of pKa 1-7
IPC: C07C45/67
Filed: 1975-11-18
Abstract: Cis or trans isomers of alpha, beta-unsaturated aldehydes of formula (IA) or (IB) are converted into the other geometric isomer by heating at 30-400 degrees C in the presence of an acid having a pKa of 1-7 as catalyst. where R1 is hydrocarbyl which may be unsaturated R2 and R3 are independently H, hydrocarbyl or a heterocyclic radical and R2 is different from R1. Each of R1-3 can form a heterocyclic group via an O, S or N atom and the groups R1-3 can be substd. by 1-3 alkoxy groups with up to 5C atoms, 1-3 alkoxycarbonyl groups not contg. more than 6C atoms or 1-3 halogen atoms. Previous processes have used iodine catalyst and light or a strong acid and a complex forming cpd. such as pyrocatechol. The former process gives rise to decomposition products difficult to remove formed by hydriodic acid; the latter both gives rise to by-products and is a corrosive process. The new process gives a high selectivity and as a result one or both isomers may be recovered with a high selectivity.

Title: Hydrocarbon prods mfr - by carbonisation of coal, scrap rubber or plastic or domestic sewage under reduced pressure
IPC: C01B31/08
Filed: 1976-01-29
Abstract: Prodn. of useful hydrocarbon products from an organic raw matl. composed particularly of coal or other analogous carboniferous matl. such as cut up motor tyres, industrial plastic waste or household sewage consists of circulating the raw matl. through an elongated tubular element, maintained at a temp. of ca. 425 degrees -98/degrees C in the virtually complete absence of oxygen and by extracting the gases and vapours from this tubular element at a reduced pressure of 50-150 mm Hg, Advantageously, the raw matl. is agitated or turned over as it passes through the tubular element, to increase the surface area of contact between it and the inner surface of the element. The use of reduced pressure in the tubular treatment element ensures that liq. and gaseous hydrocarbons are drawn away before secondary reactions e.g. cracking, re-polymerisation can occur in contact with the carbonised residue.

A portion of the beam separates from the remainder so that it can be lowered with a grating suspended from it. It is then raised and the grating conveyed onwards to pass between doors to enter a chamber between shot blasting turbines (2). In their refrigerated condition, the excess paint is more easily removed by the shot blasting turbines (2). In their refrigerated condition, the excess paint is more easily removed by the shot blasting treatment.
