Abstract: 631,942. Fluid-pressure gauging-apparatus. HUGGENBERGER, A. U. March 7, 1946, No. 7186. Convention date, April 2, 1945. [Class 106 (ii)] In gauging-apparatus there are at least two chambers with outflow nozzles to which a gas is fed in parallel under pressure, the nozzles are directed one towards the other to act on a control body movable between them, this control body being an element to be measured or connected thereto, and the change in pressure in the two chambers is utilized for measurement. As shown in Fig. 3, a gas, such as air, is supplied to chambers 8, 7 through pressure regulators 1, 2 and inflow nozzles f<SP>1</SP>, f<SP>2</SP>, respectively, and passes to outflow nozzles F<SP>1</SP>, F2 arranged on opposite sides of a member P which may be a work-piece to be measured or a member movable between the nozzles in accordance with some value to be measured. Pressure gauges 5, 6 measure the pressures pc<SP>1</SP>, pc<SP>2</SP> of the air behind the inflow nozzles, and a differential gauge 13 gives the pressure difference between the pressures p<SP>1</SP>, p<SP>2</SP> in the chambers 8, 7. If the pressures pc<SP>1</SP>, pc<SP>2</SP> are equal and all the nozzles of equal diameter, then the gauge 13 will indicate the position of the member P relatively to the nozzles F<SP>1</SP>, F2. The pressures pc<SP>1</SP>, pc<SP>2</SP> can be varied, and the nozzles may be of different diameters to suit the particular gauging operation. One practical form of gauge for gauging the thickness of a work-piece 22 is shown in Fig. 5, wherein a member 16, connected by rods 18 to a feeler 20 engaging the work-piece, is arranged between opposed nozzles 25. The casing 17 is rigidly secured to a work-table 23. Air from the nozzles escapes through passages 29 and is directed towards the gauging feeler. A spring 27, adjustable by a screw 28, bears on the member 16. The member P, Fig. 3, may be secured to a specimen being subjected to a stress test whereby during tension or bending the change in length between two points on the specimen can be measured. A clamp holding the two nozzles Fl, F<SP>2</SP> may be secured to the specimen at one of these points, and the member P secured to the specimen at the other point. In a modification shown in Fig. 7, a bracket 41 connecting the two outflow nozzles 42, 43 is adjustably mounted in a holder 39 at point A on a specimen 45, and a member 38 pivotally mounted by knife-edges 40 or other means to the holder and a point B on the specimen. The member 38 in this case magnifies the movement of the point B relatively to the point A. In cases where comparatively large extensions of a test specimen are to be measured, the two outflow nozzles are joined together, slotted at opposite sides of a separating plate to allow each nozzle to discharge, and secured to one point on the specimen. A sleeve, surrounding but not long enough to cover the combined exit slots, is carried by an arm secured to the second point on the specimen.

The paraffin wax may be macro- or micro-crystalline, and may contain mineral oils; the residue after cracking heavy paraffin hydrocarbons in the preparation of alkenes may be used.  The calcium soap may be prepared from oleic acid, palmitic acid, stearic acid, hydrogenated castor oil, train oil fatty acids and acid products obtained during the oxidation of heavy mineral oils and paraffin wax or mixtures of said materials. Lubricating oils which may be used for the grease include all the natural and synthetic oils known to be suitable for calcium soap lubricating greases, especially mineral lubricating oil distillates and residual mineral lubricating oils.  The calcium soap is preferably formed in situ in the lubricating oil by saponifying the fatty acid or a glyceride thereof, dissolved or dispersed in the oil, with lime, at an elevated temperature.  The primary calcium soap grease should contain between 0.3 per cent. and 3 per cent. by weight of water based on the final composition containing paraffin wax, to provide a suitable grease structure. The final grease may also contain anti-oxidants, extreme pressure dopes and oiliness agents; also gelling agents such as metal oxides, hydroxides and silicates, examples being silica, magnesia, calcium hydroxide and magnesium silicate.  The wax is preferably added while the primary grease is between 20 DEG C. and 30C DEG ., but may be added when the primary grease has cooled, while being stirred, to below its dropping point, the final mixture being stirred until the temperature has fallen to 60 DEG C. or lower.
