Abstract: Milk containing animal feed compositions, and aqueous feeds containing them, are stabilised by the presence of a complex salt consisting of ammonium, alkali metal or alkaline earth metal ions and formic acid in which the ratio of acid to ions is from 2:1 1 to 4:1. Preferred complex salts are those commonly known as ammonium tetraformate and potassium diformate. 
     The milk containing compositions can contain 0.10 to 5, preferably 0.5 to 2% wt. of complex salts, corresponding figures for the aqueous feeds being 0.01 to 0.5, preferably 0.05 to 0.2% wt. 
     The complex salts can be added as solids, when appropriate, or as an aqueous solution or distributed on a comminuted solid carrier (e.g. finely divided silica).

Abstract: The machine may function as a rotary compressor, vacuum pump, expansion engine, or blower. Two rotors (1,2) interengage inside a housing (5). The first rotor (1) opens and closes higher pressure ports (15) in the end walls of the housing (5). The first rotor (1) has a larger diameter hub (6) than that (8) of the co-acting second rotor (2) so as to permit the ports (15) to be larger in area. The optimum number of teeth or lobes (7,9) for each rotor (1,2) is two. 
     So as to reduce an internal throttling loss between the large diameter first rotor hub (6) and the casing (3), (a) the hub (6) has two .grooves (10) instead of one and (b) the grooves (10) are large in angle. 
     The lobes (7) on the first rotor (1) are smaller in angle whereas the lobes (9) on the second rotor (2) are larger in angle. 
     The rotary shaft power transmitted through the two timing gears is less than one half of the total.

Abstract: A small amount of Si0 2  is added to a sodium borate solder glass for making tubesheets in hollow fiber, high temperature battery cells. The glass is more easily ground and has a lower softening temperature. When the powdered glass is fused, to form the tubesheet and sealingly engage the fibers (3), the fiber-weakening fluxing action of the glass is considerably reduced. The invention also resides in a method of making the tubesheet whereby the internal structure is modified sothat it has a closed upper surface (2) whilethe underlying structure of the tubesheet is more open or porous (1).

Abstract: An expansible tube valve has a flexible tube (30) stretched around a circular barrier (28) between inlet and outlet slots (22, 24) and is conditioned to enable flow in an annular path around the barrier when upstream pressure overcomes pressure in a control jacket (41) around the tube. A second flow path directly through the barrier is normally closed off by a poppet valve (48) engageable with a seat (44) around the passage. A spring (64) augmented by a control pressure biases the valve toward closed position and is preferably set so that, only after capacity of the flexible tube valve is reached or approached, does the poppet valve open to answer the need for high pressure demand downstream or for relief of a high pressure surge upstream.

Abstract: A method and apparatus for intensifying contrast during the recording of masters in electronic image processing wherein a master is scanned opto-electronically and an image signal is produced as well as two unsharp masking signals by scanning a first unsharp masking area and an enlarged second unsharp masking area around the current image point. Differential signals are generated from the image signal and each of the two unsharp masking signals and the two differential signals thus formed are mixed together in a selected ratio. The mixed signal is divided into positive and negative correction components which can be differently amplified and after comparison to threshold signals are combined to form a correction signal which has an effective width which depends on the mixing ratio. The mixing ratio may for example, be dependent on the gradient and/or the contrast of a master contour. The correction signal thus formed is then superimposed on the image signal so as to provide contrasted intensification and the contrast enhancement can be matched to the properties of the master by controlling the effective width of the correction signal.
