Abstract: 637,487. Bridge circuits. WIGAN,'E. R. Jan. 6, 1948, No. 382. [Class 37] A meter for indicating the mean level of a fluctuating voltage comprises a bridge circuit to which the fluctuating voltage is applied and comprising in one arm a rectifier so that the bridge is balanced at a predetermined datum level of the applied voltage and .fluctuations from this level cause departures of the bridge circuit from its state of balance. A bridge comprises three resistances A, B, C, e.g. of 1000 ohms each, and a dry contact metallic rectifier D having a resistance of 1000 ohms at an applied voltage of 1 volt and connected so that its resistance decreases with increasing applied voltage. The fluctuating voltage, the mean level of which is to be indicated, or a D.C. voltage derived therefrom is applied to input terminals 1 and a centrezero galvanometer G is connected to indicate the extent of unbalance. The apparatus is particularly suitable for indicating the mean levels of speech signals, which are in the form of short bursts having an average level of, say, 2 volts. A small percentage fluctuation in the signal voltage may be made to cause a large deflection of the galvanometer, which may be given a long time constant so that a true integration of the signals is obtained without correspondingly increasing the effective time constant governing the response of the instrument. The time constant of the galvanometer is controlled by shunt resistances. The galvanometer may be calibrated to read directly in decibels above and below the reference level. A relay may be substituted for the galvanometer and may control a motor adapted to operate on the amplifier &c. giving rise to the fluctuating voltage so as to reduce the fluctuations and restore the balance of the bridge. The movements of the attenuator, gain control, &c. controlled by the motor may then be made visible or recorded, so that a constant level signal output is maintained and an accurate record of the fluctuations of the input level of the signal is obtained.

Title: An improved apparatus for measuring the internal friction and the modulus of elasticity of solids and for the measurement of the coefficient of surface friction between two solids
IPC: G01N3/34
Filed: 1950-01-10
Abstract: 671,536. Testing physical qualities. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, ET CIREY. Jan. 10, 1950 [Jan. 10, 1949], No. 652/50. Class 106 (ii). Apparatus for determining internal friction and modulus of elasticity of solids by the rotational flexion method comprises a testpiece 1, Fig. 3, surrounded by an extension-piece 2 of thin steel tube within a tubular shaft 3 carrying at its upper end a collar 4 which is ground to fit a bearing 5 mounted in a fixed sleeve 6. At its lower end the shaft 3 extended by a collar 8 is mounted in a ball-race 9. The test-piece is fitted in the bottom of the shaft 3 by a slotted collet 10 which has a shoulder 11 and on which is screwed an intermediate sleeve 12 which rests at its upper end through flange 13, on the collar 4. The sleeve 12 and test-piece 1 may be centred by adjustment of the micrometer screw 16 bearing on the flange 13. Rotation of the test-piece is effected by a belt 18 running in a groove 19 of the collar 8. The load is applied to the test-piece via the needle end 21 of the extension 2 by means of a cable 22, Fig. 2, attached to a ball-race 21a. The cable passes over a pulley 23 and is attached at the far end to a weight 24. Measurement of deflection of the needle point 21 is made by means of a small mirror 35, Fig. 4, mounted on a spring 32 fixed at the base to a supporting pillar 28 and responsive at its other end to movement of a fork 36 resting on the needle 21. When the extension-piece 2 is submitted to the pull of the cable 22 with the test-piece at rest the latter flexes and the extension-piece tends to displace the fork 36 from a vertical position. When in addition, the assembly of the test-piece 1 and extension 2 is given a rotational movement the extension-piece tends to cause the frame 29 to pivot about the vertical axis 30. These two displacements are transmitted to the mirror 35 which deflects a beam of light across a screen from its original position A, Fig. 6, towards B. The abscissa of B gives the lateral deflection from which the coefficient of internal friction can be calculated while the ordinate of B gives the deflection in the direction of pull from which the modulus of elasticity is measured.

Title: Improvements in and relating to the dimerisation of olefines
Inventor: GODDARD REGINALD EDWIN
IPC: C07C2/30
Filed: 1957-01-09
Abstract: In the dimerisation of one or more olefines, at least one of which does not contain a terminal double bond, at elevated temperature and pressure, the catalyst used is an organo-compound of aluminium and a metal, or a reducible compound of such metal, selected from copper and transition metals of Groups 3 to 8 of the Periodic System excluding metal; the organoaluminium compound is an aluminium hydride in which one or more hydrogen atoms are replaced by alkyl groups. Suitable olefines not containing a terminal double bond are butene-2, pentane-2 and heptane-3. Alpha-olefines may be codimerized with such olefines, e.g. mixtures of butene-2 with butene-1 or propylene may be dimerised. The aluminium compound is preferably a trialkyl, e.g. the triethyl, tripropyl or tributyl, and is used in amounts of 1-30% based on olefine.  Metals specified are titanium, chromium, iron and cobalt and preferred compounds are chlorides; the metal or salt may be supported on kieselguhr.  Amounts of 0.01-5% of the metal based on olefine are used.  Temperatures of 100-250 DEG  C. and pressures of 50-400 atmospheres are used.  An inert solvent for the olefine may be present such as paraffinic, saturated alicyclic and aromatic hydrocarbons.  Water and oxygen should not be present and an inert atmosphere such as nitrogen may be used. The dimers formed are useful as feed materials for a carbonylation process to give alcohols and aldehydes.  If the metal used in the dimerisation catalyst is a carbonylation catalyst, e.g. iron or cobalt, no further catalyst need be added nor the dimers separated.  Carbonylation may thus be effected without pressure reduction.

Title: Production of alkoxyalkenes
Inventor: HALL REGINALD HAROLD
Filed: 1954-01-13
Abstract: A 1 : 1 : 3-trialkoxyprop-2-ene is produced by reacting a 1 : 1 : 3-trialkoxy-2-halopropane at elevated temperature with an alkali metal alkoxide of 4-8 carbon atoms in solution in an alkanol of 4-8 carbon atoms, the alkoxide and the alkanol each having a straight chain of at least 3 carbon atoms.  Preferably the alkali metal alkoxide is used as a solution in the corresponding alkanol which in turn corresponds to the alkoxy groups in the starting material. Suitable alkoxides are potassium or sodium butoxide. The reaction may be effected at a temperature in the range 100 DEG  to 160 DEG  C., preferably 120-140 DEG  C., and an excess of alkoxide is used.  The product is treated with sufficient water to hydrolyse excess alkali metal alkoxide and dissolve the metal halide, and the trialkoxypropene is receovered from the alcohol phase, for example by distilling off the alkanol under reduced pressure.  The 1 : 1 : 3-trialkoxy-2-halopropane starting material may be prepared by reacting acrolein with an aqueous hypo-halogenous acid, distilling the resultant a  - halo - b  - hydroxypropionaldehyde in the presence of steam and thereafter reacting the formed a -haloacrolein with an alkanol of 4-8 carbon atoms in the presence of an acid, e.g. sulphuric acid, while azeotropically removing the water of reaction. The trialkoxyprop-2-enes may be reacted with amidines, e.g. guanidine, to give 2-substituted pyrimidines such as 2-aminopyrimidine. They may also be condensed with a pyrrole base to give photographic sensitizers as in Specification 696,646.  In examples: (1) 2 - chloro - 1 : 1 : 3 - tri - n - butoxypropane is refluxed with potassium-n-butoxide in n-butanol to give, after water washing and fractional distillation, 1 : 1 : 3-tri-n-butoxyprop-2-ene; (2) 2 - chloro - 1 : 1 : 3 - tri - isobutoxypropane was similarly treated with potassium isobutoxide in isobutanol to give 1 : 1 : 3-triisobutoxyprop - 2 - ene; (3) the process of Example (2) is repeated using sodium isobutoxide; (4) acrolein in water is treated countercurrently with chlorine and the product is distilled to give a -chloracrolein which is reacted with isobutanol and concentrated sulphuric acid while azeotropically removing water, and the crude product is fed to a fractionating column with potassium isobutoxide in isobutanol from which is obtained a fraction comprising 1 : 1 : 3-tri - isobutoxyprop - 2 - ene; (5) 2 - chloro - 1 : 1 : 3 - tri - isobutoxyprop - 2 - ene is refluxed with a solution of potassium in excess 2-ethylhexanol and the product is distilled to give a b -alkoxyacrolein acetal which is condensed with guanidine hydrochloride to give 2-aminopyrimidine. Specification 763,467 also is referred to.
