Title: Cable railway thermic overloading safety device - with heat sensitive plastic battens and pressure sensitive spring store
IPC: B61B12/12
Filed: 1975-03-24
Abstract: The safety traction cable clamping mechanism provides thermic overloading protection on cable railways, and incorporates a top cable clamp shoe and a bottom one.

Title: Chromate passivation of metal coatings on steel - in dil. chromic acid bath fed continuously through ion exchange resin
IPC: C23C22/86
Filed: 1975-09-30
Abstract: Ferrous metals (1) coated with metals (2) such as Zn, Cd, Sn etc., are passivated by immersion in a bath contg. chromic acid. The novelty is the use of a low concn. of chromic acid, so that metals (2) dissolved in the bath during treatment can be continuously removed by feeding the bath through an ion exchange resin, becaue the accumulation of metals (2) in the bath interfers with the passivation treatment. The concn. of chromic acid in the bath is pref. 4 to 5 times lower than that of conventional baths. The pref. bath contains 2-4, esp. 2.5 g/l CrO3, 4-6, esp. 5 ml/l conc. HCO3, and 0.15-0.5 esp. 0.25 ml/l H2SO4 (66 degrees Be); used at 20-60 degrees C., pref. 55 degress C. The pref. resin is a strongly cationic resin, e.g. Duolite C.20 (RTM), and the resin is pref. regenerated by a strong acid. Two ion exchange units are pref. used alternately, one being used while the other is regenerated. Uses for example, on zinc coated steel parts. Continuous operation with continuous removal of the Zn from the passivating soln.

Title: Polluted air purification equipment - has outermost concentric cylinder with removable end and manifold flanged to inner one
IPC: F23G7/06
Filed: 1975-11-18
Abstract: The equipment purifies polluted air by combustion of the polluting agents, and has three or four concentric cylinders forming annular spaces in which the polluted air flows, exchanging heat by contra-flow before entering the furnace proper formed by the innermost one, into which fuel is fed to give by combustion the oxidation temperature of the polluting agents. The outermost cylinder is sealed at one end by an arched plate or bottom, and has at the other a larger-diameter manifold, giving an even flow along the cylinder. Plate or bottom are removable to allow direct discharge of burnt gases. It is shorter than the next one inwards, over which it fits detachably by a flange on the manifold, so that the inner one can be supplied direct. There is a tapping in the manifold by which gases are discharged. The next cylinder is supplied with polluted air by a tapping in its portion left free, and is coupled to the furnace by a semi-toroidal section. The furnace is closed at the other end by an arched base with a central hole having a spigot on the inside, and through which air and fuel are introduced. The fuel nozzle is telescopic, varying the length of the furnace exposed to heat and flame.

Title: Direct drive transmission between inclined shafts - has sliding rods projecting from barrels on shaft ends and connected by fork ends
IPC: F04B1/24
Filed: 1976-01-20
Abstract: The transmission described permits direct drive between two shafts aligned relative to each other at angles up to and including a right angle. In addition, the angle may be changed easily whilst under load. The end of each shaft (3a, 3b) consists of a barrel in which are mounted a number of sliding rods or pistons (7, 8, 9) all on the same pitch circle diameter. The ends of the rods projecting from one barrel are connected to those projecting from the other by fork ends (11) or ball joints. As the ensemble rotates, the pistons slide in and out of their housings and also rotate, the amplitude of these movements depending on the angle between the two shafts and reaching a maximum when the shafts are at right angles. The pistons in one half can be used as pumping elements, the output duty of the pump then being easily varied by changing the relative angle between the shafts.
