Title: Device for testing constructional material by means of oscillations of flexure of test-pieces
IPC: G01N3/34
Filed: 1929-04-24
Abstract: 332,299. F÷ppl, O. April 24, 1929. Testing physical qualifies of material.-In testing material by oscillations of flexure of test pieces secured at one end and carrying a mass at the free-end, this mass is designed to apply a torsional moment at least equal to the ordinary moment. Fig. 1 shows the ordinary form with a diagram of the variation or bending moment M along the specimen. Fig. 2 shows a similar view of a dumbbell form of mass secured at the end of the specimen and shows the usual moment M<1> together with the constant torsional moment M<2>. Fig. 3 shows a dumbell iorm where the C.G of the mass is at the end c of the specimen which is caused to oscillate about a point d half-way along its length thereby equalizing the total moment along its length. In the practical form Figs. 4, 5, 6 the apparatus is supported by a structure formed by uprights 1, 2 and cross stays. Secured to bridge-pieces 7, 8 are angle-irons, 9, 10 to which the lower ends of the specimens f<1>, f<2> and also of spring strips h<1>, h<2> are fastened by a clamping plate 12 and bolts. The upper ends of the specimens carry the oscillating mass 15 in the form of a cross with transverse arms 16, 17 the ends of which receive the tops of the specimen and are secured thereto. The imaginary axis about which the masses oscillate is arranged at half the height of the specimen. Special auxiliary springs h<1>, h<2> absorb the moment M<1> due to lateral displacement of the mass. These springs are held by narrow ledges 19 in the arms 16, 17 without being secured thereto. The device is actuated by two pairs of electromagnets 20, 20<1>, and 21, 21<1> opposite the enlarged ends of the mass. They are selectively excited by coils 25 so that the two diametrically opposite magnets are excited together. An arc 32 carried by the mass contacts with the end of a change-over switch lever 30 and carries it against a stop 33 or 34 thereby closing a circuit for two opposite magnets. With reversal of the motion of the mass, the other pair of magnets are excited. A diagram of connections is given in the Specification. An electric counter is provided for counting the oscillations, and means for cutting off the exciting current on fracture of the specimen or upon an excessive amplitude, of vibration.

Title: Improvements in or relating to process for regenerating carboxylic acids from their salts
IPC: C07C51/02
Filed: 1952-05-26
Abstract: Carboxylic acids are recovered from an aqueous solution of their alkali metal salts by extracting the solution with liquid carbon dioxide at a temperature from slightly above the freezing-point of the solution to about 88 DEG  F. and at about 555 to about 1055 p.s.i.g., the carbon dioxide being used in a weight ratio of at least about 0.5 parts of carbon dioxide to about 1 part of salt solution, e.g. about 0.8 : 1, a stream being withdrawn which contains liquid carbon dioxide and the liberated acids.  The salt solution may be obtained by stripping a mixture of acids and hydrocarbon with an aqueous alkali metal bicarbonate or carbonate to neutralize the acids.  The raw oil obtained by reducing carbon monoxide with hydrogen in the presence of an iron catalyst may be treated.  Salts not regenerated by the carbon dioxide are preferably recycled to the neutralizing step.  Weight ratios of 0.6 to about 1.1 parts of light acid, i.e. acids of up to 5 carbon atoms, recycle salts to 1 part of fresh feed acid salts is generally sufficient for complete recovery of acids. Temperatures of about 40-85 DEG  F. and pressures of about 850-1000 p.s.i.g. are preferred.  Carbon dioxide liberated from the bicarbonates may be compressed and used in the process.  The carbon dioxide is removed from the acids by flash distillation. With sodium salts an aqueous concentration of about 20-25 weight per cent is preferred and with potassium salts concentrations of about 40 per cent may be treated.  Sodium and potassium hydroxide are also specified for neutralization.  Examples are given of the treatment of hydrocarbon synthesis oil and diagrams show suitable arrangements of apparatus.
