Title: Improvements relating to the preparation of gel-like monohydric phenol-formaldehyde condensation products
IPC: B01J39/18
Filed: 1942-10-31
Abstract: Gel-like monohydric phenol-formaldehyde resins having ion-exchange properties are obtained by heating an alkali salt of a monohydric phenol with a molar excess of formaldehyde in the presence of an alkali catalyst until a gel-like mass is obtained and then drying the gel.  Molar proportions of at least 1.5 and preferably 2 or 3 of formaldehyde to one of the phenol are used. The phenol salt is prepared by adding sufficient alkali to the phenol to form the salt and leave excess of alkali to act as catalyst.  40 parts sodium hydroxide dissolved in 200 parts water are mixed with 96 parts of phenol and 600 parts of a 37 per cent solution of formaldehyde are added; the mixture was heated to 100-110 DEG  C. for about 3 hours when gelation occurred, the gel being then dried for 3 hours at 100 DEG  C.

Title: Electron probe analysis of electrical and magnetic fields
Inventor: NIXON WILLIAM CHARLES
IPC: H01J37/29
Filed: 1968-04-03
Abstract: 1,249,305. Electron microscopes. W. C. NIXON, and R. S. PADEN. 28 March, 1969 [3 April, 1968], No. 15934/68. Heading H1D. [Also in Division G1] In a method of analysing the electrical and/or magnetic field distribution around a structure S, such as an electrode structure for use in an electron optical system, the structure is repeatedly scanned with a finely focused electron beam, e.g. in a scanning electron microscope G, A, L 1 , L 2 , and a two-dimensional image representing equipotential lines in the field distribution is formed from electrons transmitted through or reflected by the structure for each scan; the structure being held at a mean potential which subjects the electron beam to a strong retarding field to slow down and turn back some of the electrons, this potential being altered between scans. The transmitted or secondary electrons after detection at D are used to provide a signal which is amplified and then applied to an oscilloscope C which is scanned in synchronism with the beam. The various plots obtained at different retarding potentials build up a map of the field distribution around the structure. High energy electrons at, e.g., 20 KeV. are used to form the probe so as not to be upset by stray fields, while a similar retarding potential is applied at the target structure so that the electrons will have a relative energy of only a few volts and will be strongly influenced by the target field distribution. For more complex structures, such as the anode grid structure of a valve, the whole procedure is repeated varying the relative potentials within the structure at given mean potentials, to build up a map of the field distribution around the structure in depth. The arrangement may be applied to the analysis of magnetic fields, to the analysis of electric fields at the surfaces of e.g. solid integrated circuit elements, and also to the electron emission analysis of Auger electrons, in which case the energy at impact may be in a range up to 1500 volts instead of only a few volts.

In the arrangement shown, the two ducts are separated from one another by a fireproof partition 3, the bus-bars of each set being arranged in separate oil-filled conduits 5, from which spout-like members 6 pass through the floor 4. Conductors connected to the busbars pass through the members 6 to sockets adapted to be engaged by contact-plugs on the withdrawable part of the switchgear, the arrangement being such that the three sockets associated with the bus-bars of each set are disposed in a straight line. The feeder 7 is connected through a current transformer chamber 9 to three phase conductors arranged in oil-filled chambers 10, each chamber being provided with a pair of downwardly extending members 11 provided at their lower ends with sockets arranged in line with the sockets associated with the two sets of bus-bars.
