Abstract: ABSTRACT OF THE DISCLOSURE      A method is disclosed for preparing fatty acid isethionate soaps through direct esterification wherein the catalyst is quenched by an alkaline compound at the end of the esterification.  Quenching inhibits transesterification between isethionate and later added stearic acids.  Transesterification is undesirable impairing lather and bar soap firmness.  The traditional stripping of lower molecular weight fatty acids is no longer necessary where low ratios of fatty acids to isethionates are utilised.  Alternatively, stripping can be avoided with traditional molar ratios provided water co-distilate fatty acid is not recycled.  Finally, it has been shown that zinc catalysed reactions provide optimum yield and low corrosion at pH about 2.0 to 2.5.

Abstract: Abstract Production of Ion Exchange Membrane A method of increasing the surface area per unit weight of an ion-exchange membrane in which the membrane in the form of a sheet is expanded by dry stretching in order to effect the increase in surface area per unit weight and in which the membrane comprises an organic polymeric material having a plurality of fixed anionic groups associated with cations at least some of which comprise an organic group or a plurality of organic groups.  A membrane having the defined cations is particularly susceptible of expansion by stretching to produce a membrane which remains taut and unwrinkled when used in an electrolytic cell.  Use of the expanded membrane results in a decreased cell voltage.

Abstract: Abstract of the Disclosure Known radiation pyrometers have a lens mounted at the forward end of a tube that is located within an outer tube which is supplied with purge gas.  In the present invention, the lens is mounted in a rear portion of an inner tube that is stepped to a forward portion of reduced diameter that is open at its forward end.  The outer tube extends coaxially around the inner tube and is separated from it by an annular gas passage. The outer tube has an aperture at its forward end that is smaller than the external diameter of the forward end of the inner tube and larger than its internal diameter.          Gas inlets in the outer tube open into the passage, the inlets being located rearwardly of the forward end of the inner tube, and the area of the gas inlets being greater than the gap between the forward end of the inner tube and the outer tube.  Gas flows through the inlets, along the passage, across the forward end of the inner tube and out the apertures thereby setting up a substantially constant pressure in the rear portion of the inner tube and reducing the entry of contaminants.

Abstract: ABSTRACT       The present invention provides a method which is of the guided near field type so as to exploit fibre propagation characteristics, and requires no complex processing of a measured value.  In this method, an image of the fibre output end is radially scanned, and for each value of a distance r from the image axis, two image-intensity measurements are effected, the first after optically filtering the beam emerging from the fibre so as to modulate the beam according to a factor p4 (with p = a ? sin  .THETA., .THETA. being the angular beam coordinate, and a the dis-tance of the generic filter point from the fibre output end), the second meansurement being effected by directly collecting the beam leaving the fibre end, the refractive index value at that point being derived from the ratio  between the first and the second measurement.

Abstract: Abstract of the Disclosure Air-Fuel Ratio Control System Having A   Fluid-Powered Broken-Link Mechanism The subject air-fuel ratio control system for an engine includes a fluid-powered broken-link mechanism which is operatively linked between an air-fuel ratio control device and a fuel quantity control member, such as a fuel injection pump rack. During startup of the engine, the mechanism disables the device to permit excess fuel delivery.  The device is automatically activated after engine startup by the mechanism solely in combined response to the existence of engine oil pressure and a governor moving the fuel quantity control member from an excess fuel delivery position to a predetermined position referred to as an air-fuel ratio control setting.  This construction minimizes the duration and quantity of any smoke produced during engine startup, simplifies the cost and construction of the air-fuel ratio control device, and permits relatively easy adjustment of the air-fuel ratio control setting.
