Title: Magnetic field well logger
IPC: G01V3/26
Filed: 1940-10-15
Abstract: 544,676. Magnetic tests and measurements. STANDARD OIL DEVELOPMENT CO. Oct. 15, 1940, No. 15286. Convention date, Oct. 28, 1939. [Class 37] Bore holes and wells are logged by determining the vanation of the magnetic field in the different formations penetrated. At the surface of the earth 5 is placed a frequency meter 6 and a detector 7. Conductors 8 are contained within a cable 9 and connected to a D.C. motor 10 suspended within the bore hole 1, which passes through strata 2, 3, 4. A battery 11 is connected to the conductors 8 at the earth's surface and provides power to operate the motor 10, to the shaft of which is attached a coil 12 connected by slip-rings 13 and conductors 14 contained in a cable 15 to the detector 7, which may be an A.C. voltmeter. The frequency meter 6 enables the speed of the motor 10 to be kept constant. A commutator may be substituted for the slip-rings 13 and a D.C. voltmeter employed as detector. The motor 10, which rotates the coil 12 at a constant speed about a diameter is lowered down the bore-hole 1 and the magnetic field at different levels is measured by observing the voltage generated by the coil 12. In a modification the motor rotates a disc about a diameter within a fixed coil so that an alternating current is induced in the coil when the coil and disc are in a magnetic field. The motor and coil may be enclosed in a fluid-tight container of non- magnetic material. The D.C. motor may be replaced by an A.C. synchronous motor. Instead of a motor producing a rotary movement a device producing a uniformly recurring movement may be attached to the coil 12 or the disc.

Title: Improvements in hinges
IPC: E05D3/02
Filed: 1932-05-31
Abstract: 398,963. Hinges. TIMINGS, S., 55, Great Hampton Street, Birmingham. May 31, 1932, No. 15379. [Class 65 (ii).] In a hinge, particularly for mirror sections, comprising two plates connected together, one plate is adapted for attachment to one of the members to be hinged and the other has associated with it a detachable plate adapted to be secured to the other of the members to be hinged, one of the associated plates having portions pressed up or bent over to form opposed channels adapted to receive portions of the other plate and to be disengaged therefrom by relative movement parallel to the hinge axis. The portions of the second associated plate which engage with the channels of the first may also be formed by pressing up or bending over portions of the plate. The channels and the portions engaging therewith may be of diverging or converging form along the length thereof, so as to avoid looseness and to limit the engaging movement. The plates are adapted to be formed by pressing or stamping from sheet metal. In the form shown in Fig. 3, one plate 6 of the hinge is arranged for screwing to one of the members to be hinged, while the other plate 7 has parts 24 of its opposite edges bent as shown to engage channels 23 formed by the bent-over edges of a plate 22 fixed to the other member to be hinged ; the lower ends of the channels 23 are closed in to form stops for the engagement of the parts 24 on plate 7. In a modification, the plate 7 may have a single downwardly-extending tongue pressed up out of it to engage the channels 23 on member 22. Alternatively, the edges of the plate 7 may be bent inwardly to form channels similar to 23, the top of plate 22 being bent to stand forward from its lower part and form a tongue to engage the channels on plate 7 ; in a modification of this arrangement, the channels on plate 7 are formed by striking up parts similar to the parts 24 in Fig. 3 but reversed to face one another.

Aliphatic carboxylic acids specified are acetic, propionic, butyric and valeric acids, and mineral acids mentioned are sulphuric and hydrochloric.  The aromatic hydroxy compounds may be phenols and naphthols and may contain substituents such as methyl and carboxylic groups or halogen atoms.  The reaction may be conducted at 90-120 DEG  C. by mixing the aromatic hydroxy compound with hexamethylene tetramine and paraformaldehyde in glacial acetic acid with addition of concentrated mineral acid or by addition of acetic acid to a melt of the reactants.  Examples describe (1) the preparation of 3 : 5-dichloro-, 3 : 5-dimethyl-, 5-methyl-, 3-methyl-5-chloro-, and 3-chloro - 5 - methyl - 2 - hydroxy - benzaldehydes, 2 - hydroxy - 1 - naphthaldehyde, 2 : 6-dihydroxynaphthalene - 1 : 5 - dialdehyde, 2 : 3-dihydroxynaphthalene - 1 : 4 - dialdehyde, and 2 - hydroxy - 3 - carboxy - 1 - naphthaldehyde; (2) the use of aqueous or gaseous ammonia and paraformaldehyde, and of ammonium carbonate or acetate and paraformaldehyde in place of hexamethylene tetramine is illustrated.
