Title: Testing material for irregularities of thickness
Inventor: HALL BRIAN REGINALD
IPC: G01B7/06
Filed: 1965-04-27
Abstract: 1,097,760. Measuring thickness electrically. ILFORD Ltd. April 26, 1966 [April 27, 1965], No. 17689/65. Heading G1N. Irregularities of thickness of sheet material such as an aqueous layer of photographic emulsion 11, Fig.3, on a cellulose base 10 are measured by mounting at least one pair of spaced apart drive electrodes 20 to be capacitively coupled to one surface of the material, applying equal alternating voltages of opposite phase to the respective electrodes, and using a probe electrode 21 situated between the two drive electrodes of a pair to measure the alternating potential at the adjacent point in the material surface. The probe electrode is placed half-way between the drive electrodes and detects zero potential in the absence of irregularities of material thickness. Each drive electrode may be connected to an identical electrode 20' arranged on the opposite side of the sheet material to reduce spurious errors in the probe output due to movement of the sheet perpendicular to the electrodes; and further correction for such errors is achieved by phase detecting the probe electrode output with reference to the drive potential, to separate the potential drop due to resistivity of the sheet from that due to capacitance of the electrodes, these drops being 90 apart. An array of drive electrodes 20, 20' may be arranged (also Fig. 2 not shown) transverse to the direction of movement of the sheet, and be arranged for reciprocatory movement over a distance equal to half the separation of the drive electrodes, alternate drive electrodes being connected to one terminal of the A. C. supply and the remainder to the other. The output of the probe electrode is fed to an amplifier 25 and a cathode ray tube 26, the beam of which is deflected, or its intensity modulated, thereby, and a plurality of traces corresponding to the plurality of probe electrodes in an array may be produced. The trace for any one probe may be photographically recorded, or may be monitored by a photo-electric cell 27, this being arranged with suitable marking means to indicate when the trace deflection is over, or alternatively under, a certain limit. Edge effects affecting the outermost electrodes 20 of an array are reduced by auxiliary electrodes (28), Fig. 2 (not shown), which effectively earth the outer edge of the sheet, either by being connected to earth via respective inductances which resonate with the capacity between the electrode (28) and the sheet at the measuring frequency (e.g. 100 kc/s to 1 Mc/s); or by measuring the edge potentials by means of further electrode pairs (29) connected to amplifiers (30, 31) which energize the respective electrodes (28) to cancel the measured potential.

Title: Multi-core high-tension electric cable, consisting of a plurality of single-core cables, each being encased in a lead sheath
IPC: H01B9/00
Filed: 1930-06-07
Abstract: 344,739. Cables. CREMER, C., 17, K÷rnerstrasse, Wendenschloss, C÷penick, Germany. June 7, 1930, No. 17699. [Class 36.] In order to assist the dissipation of heat from a multi-core cable comprising a plurality of singlecore lead-sheathed cables, lead tubes preferably filled with jute or paper are provided in the filling spaces between the cores. Fig. 2 shows a threecore cable having lead tubes 4 packed with jute strands 5, disposed between the cores. The lead tubes 4, which may be adapted to carry pilot wires or a cooling fluid, preferably possess a circular crosssection prior to the twisting of the cores, the tubes being deformed into a segmental shape during the twisting operation. The sheaths 3 of the individual cables may be formed by two or more extruded lead coverings coated with a packing compound. The cores are held together by a jute covering 6, about which is applied an iron armouring 7. A layer of jute 8 completes the cable. In order to avoid pressure between the armouring and the lead sheaths of the cores, the tubes 4 may project above the circle described about the cores. In a cable having a triangular cross section, the tubes 4 are formed with a flat outer surface 12 as shown in Fig. 4.

Abstract: 699,286. High-frequency discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. July 14, 1952 [July 17, 1951], No. 17730/52. Class 39(i) A discharge tube, comprising a metal envelope 1 with cooling fins 9 and for use at very short wavelengths, in which an ovalshaped glass protective hood 2 . surrounds one or more cathode lead-in wires 3 led through the envelope of the tube with the use of glass insulators 4 and connected by flexible conductors 5 to supply contacts 6, is characterized in that a conductor in the form of a small spring 8 is arranged between each lead-in wire 3 and the internal surface of the side of the hood 2 so as to be in mechanical contact therewith. By this means the incidence of sparking and arcing to the protective hood is at least reduced, even in the case of steep-fronted voltage differences between the leadin wire and the metal tube envelope.

Title: Improvements in or relating to the manufacture of new dyestuffs of the triarylmethane series
IPC: C09B11/12
Filed: 1933-06-23
Abstract: Triarylmethane dyes are prepared by introducing the group Alk--SO3H, wherein "Alk" stands for an alkyl group of at least three carbon atoms, into the primary or secondary amino group of a triarylmethane compound by condensing a halogen-alkylsulphonic acid containing an alkyl group of at least 3 carbon atoms with a dyestuff of the triarylmethane series containing at least one primary or secondary amino group.  Or an aromatic aminosulphonic acid of the formula <FORM:0421592/IV/1> wherein R stands for hydrogen, alkyl, aralkyl or aryl, and "Alk" stands for an alkyl group of at least three carbon atoms, is condensed with components customary for the manufacture of triarylmethane dyes, and the resulting compounds oxidized.  In an example, butylphenylaminopropane-sulphonic acid (prepared by introducing b -hydroxypropylbutylaniline-(propyleneoxide on butylaniline)- into concentrated sulphuric acid, neutralizing the resulting ester and boiling this with sodium sulphite) is condensed with o-chlorbenzaldehyde and the product oxidized to a green dye for animal fibres.  Also ethylphenylaminobutane sulphonic acid (prepared by condensing ethylaniline with butyleneoxide under pressure, converting the resulting oxybutylethylaniline into the sulphuric ester by means of mono-hydrate, neutralizing and boiling with aqueous sodium sulphite) is condensed with o-chlorbenzaldehyde in presence of hydrochloric acid, and the leuco compound oxidized to the dye.  The Specification as open to inspection under Sect. 91 relates to the production of triarylmethane dyes by the introduction of the specified group alk--SO3H into triarylmethane compounds by methods known per se, but this subject-matter does not appear in the Specification as accepted.
