Abstract: 969,668. Laminates. ALLMANNA SVENSKA ELEKTRISKA A.B. March 9, 1962 [March 11, 1961], No. 9093/62. Drawings to Specification. Heading B5N. [Also in Division D1] In the production of insulating tape for winding round an electric conductor followed by impregnation with a curable resin, said tape comprising mica attached by a binder to a backing, the binder comprises a curing accelerator for the curable resin. The binder may be 1-10% of the curable resin. The backing may be of paper, matted asbestos, or woven cotton, silk or glass. The mica may be attached as a paper-like sheet or as individual flakes. The curable resin may be an epoxy, alkyd, unsaturated polyester, or phenolic resin, and may be applied in vacuo. The epoxy resin may be prepared from epichlorhydrin and 4,4-dioxidiphenyl-dimethylmethane. It may be mixed with a curing agent, e.g. phenyl glycidyl ether, tetrahydrophthalic anhydride, or hexahydrophthalic anhydride. An unsaturated polyester resin may be mixed with cyclohexanone peroxide as curing agent. The accelerator for an epoxy resin may be a polyamide containing free amine groups, diethylene-triamine, triethylenetetramine, diethylaminopropylamine, benzyldimethylamine, or metaphenylenediamine. A polyamide may be applied as a solution in a mixture of butanol and toluene or xylene, the solvent removed at 200‹ C., and moisture removed in vacuo. The accelerator for an unsaturated polyester resin may be cobalt naphthenate or dimethylaniline. The binding agent may contain a non-accelerator, e.g. an alkyd, polyester, or unsaturated polyester resin.

Abstract: 541,376. Dyeing textiles. HOPKINS W. R. E., McQUEEN, S. T., WOOLVIN, C. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 23, 1940, No. 9132. [Classes 2 (iii) and 15 (ii)] V at dyes, dyeing with. Cellulosic materials, e.g. of cotton, linen or re-generated cllullose, are dyed with vat dyes with an addition to the vat of not more than 0.2 per cent., based on the weight of the solution, of a basic water-soluble condensation product obtained as described in Specification 207,499, [Class 2 (iii)], by re-action of hexamethylenetetramine with an alkyl halide containing not more than four carbon atoms, followed by hydrolysis of the product to form a condensation product of formaldehyde with the alkylamine and recovery of this as free base.

Title: Transmission systems for high frequency electro-magnetic waves
IPC: H01J25/52
Filed: 1940-05-24
Abstract: 540,842. Electron-oscillators. STANDARD TELEPHONES & CABLES, Ltd. May 24, 1940, No. 9182. Convention date, May 26, 1939. [Class 39 (i)] Vacuum tube for ultra-high frequencies comprises a tube 33, Fig. 5, with an inner conducting surface whose axial length is comparable with or greater than the operating wave-length, an electron emissive filament 35 stretched diametrically across the tube, and a magnetic field, represented by poles 41, 42, whose lines of force are parallel to the filament. Instead of the filament, a stream of electrons projected from a gun system on one side of the tube and collected by an anode on the other side may be used. The tube is open at one or both ends, and the open ends are coupled to di-electric guides. The setup shown in the Figure is for repetition between guides 29, 30, which are sealed to the envelope 20 by insulating tubes 24, 25, provided with internal conducting layers 26 and transverse dielectric partitions 27. The tube is free to expand and contract axially while being kept in position by its ends which are slotted to avoid transverse stresses. The tube is at a given positive potential relative to the filament and the electrons describe helical paths about the lines of force of the magnetic field, and the frequency of rotation of the electrons is synchronized with the frequency of the incoming signals, and one of the resonances of the tube. Other arrangements are described in which the tube is used for receiving or transmitting oscillations. The filament is carried by resilient arms 36 secured to rigid rods 37 supported in a metal plate 39 in the envelope and connected to the leads 38. In the arrangement shown in Fig. 7, a stream of electrons 63 generated by a spiral filament 71 and anode 73 passes through an opening 62 on one side of the tuned cylinder 61 and is collected on a plug 64 diametrically opposite.

Patent GB-166317-A (GB)
Title: Electromagnetic induction micrometers
IPC: G01B7/24
Filed: 1920-03-31
Abstract: 166,317. Ford, J. M. March 31, 1920. Sounding-apparatus. - Small relative movements or changes of length are measured by causing them to vary the flux density or flux distribution in each of two normally balanced magnetic circuits. The application to a differential pyrometer or thermometer is shown in Fig. 1 in which the rods 2, 1 carry respectively iron cored transformers 4, 5, and armatures 7, 8 through which the magnetic circuits of the transformers are completed. The primary windings 11, 12 of the transformers are connected in series and are supplied with alternating or intermittent current. The secondary windings 14, 15 are connected in opposition to one another and in series with an alternating-current measuring-instrument 16. Normally, the air-gaps in the transformers 4, 5 are equal, consequently the secondary electromotive forces neutralize one another. Any relative motion between the rods 1, 2 causes a decrease of one air-gap and an increase in the other, thereby upsetting the balance of the secondary electromotive forces and causing an indication on the instrument 16, the magnitude of which is a measure of the relative motion. The transformers may be auto-connected. In order to distinguish displacements in one direction from those in the other, the secondary current may be rectified. The secondary windings may be wound on the armatures 7, 8 which two armatures may be replaced by one armature, in the form of a cross, between two inwardly facing E- shaped electromagnets. ln a modification, Fig. 2, the armatures 7, 8 are dispensed with and the secondary winding is a coil 19, normally symmetrically disposed in the fields of two electromagnets 17, 18. Relative motion between the coil 19 and the magnets 17, 18 is thereby indicated. A recording-instrument or oscillograph may replace the instrument 16.

Abstract: 1,170,518. Carpet cleaners. SINGER CO. 1 March, 1967 [4 March, 1966], No. 9620/67. Heading A4F. A machine for scrubbing and shampooing carpets, rugs, etc. comprises a chassis 17, a pair of brushes 33 rotated by an electric motor 18 and a sponge 61 for producing foam for both brushes. The sponge is positioned between a fixed plate 53 and a pivoted plate 59. Shampooing liquid is supplied to the sponge by conduits 72 from a container (not shown). The upper surfaces 37 of the brush blocks 38 are formed with cams having leading and trailing edges 49 and 47 respectively so that as the brushes rotate, each cam in turn pivots the plate 59 about its axis 58. Thus foam is alternately squeezed from each half of the sponge and supplied to the carpet, etc. In a modification, Figs. 5-7 (not shown), only one of the brush blocks 33 has a cam and springs (174) has the pivoted plate (159) to oppose the action of the cam. Thus the cam causes the plate to squeeze one side of the sponge whilst the springs cause the plate to squeeze the other side.
