Title: Compounds containing epoxide groups, their production and their uses
Inventor: HUMPHREYS KEITH WOOD
IPC: C08G59/24
Filed: 1960-05-04
Abstract: The invention comprises a mixture of isomeric epoxy compounds of the general formula <FORM:0976705/C1/1> where R represents a halogen atom or an ester group of formula -O.CO.R1 where R1 represents a hydrogen atom or cycloaliphatic or aromatic hydrocarbon residue.  The said mixture may be produced by epoxidizing a mixture of isomeric compounds of the general formula <FORM:0976705/C1/2> e.g. by treatment with organic peracids, such as peracetic acid, perbenzoic acid, peradipic acid and monoperphthalic acid.  The epoxidation is preferably effected with peracetic acid at 0 DEG  to 40 DEG C.  The unsaturated esters and halides are conveniently obtained by reaction of a carboxylic acid R1COOH or a hydrogen halide with dicyclopentadiene, if necessary in the presence of a strong acid or Lewis acid.  Examples of suitable acids are formic, acetic, propionic, benzoic, stearic and hexachloroendomethylenetetrahydrobenzoic acid.  The esters may also be obtained by esterification of hydroxydihydrodicyclopentadiene obtained by hydration of dicyclopentadiene. Detailed examples describe the preparation and epoxidation of dihydrodicyclopentadienyl acetates, stearates and chlorides.ALSO:A hardenable composition comprises a mixture of isomeric monoepoxy compounds of the formula <FORM:0976705/C3/1> where R represents a halogen atom or an ester group of formula -O.CO.R1 where R1 represents a hydrogen atom or an aliphatic, cycloaliphatic or aromatic hydrocarbon residue together with a di- or poly-epoxide and a hardening agent, such as amines or amides, polyamides, isocyanates, isothiocyanates, polyhydric phenols, phenol-aldehyde resins, reaction products of aluminium alkoxides or phenolates with tauntomeric reacting compounds of aceto-acetic ester type, Friedel Crafts catalysts and their organic complexes, and phosphonic acid. The preferred hardeners are polybasic carboxylic acids and their anhydrides. Accelerators such as t-amines and polyhydroxy compounds may be present.  The compositions may also comprise compounds of the above formula in which the epoxide groups are hydrolysed to hydroxyl and/or acyloxy groups.  Other epoxides present may be, for instance, polyepoxides of alicyclic compounds, polyglycidyl ethers of polyalcohols, such as butane-1:4-diol, or of polyphenols, such as resorcinol, bis(4-hydroxy phenyl)-dimethylmethane or condensation products of aldehydes and phenols, polyglycidyl esters of polycarboxylic acids, such as phthalic acid, or aminopolyepoxides. The compositions may also contain fillers, plasticisers or colouring agents, e.g. asphalt, bitumen, glass, fibres, mica, quartz powder, cellulose, kaolin, kieselguhr or metal powder.  A detailed example comprises the curing of an epoxide resin made from bis (4-hydroxyphenyl) dimethylmethane and epichlorohydrin with mixtures of this resin with epoxidised dihydrodicyclopentadienyl acetates and stearates, the curing agents being 4,41-diaminodiphenyl methane and phthalic anhydride.

Title: Improvements in and relating to piezo-electric substances
IPC: H01L41/41
Filed: 1930-04-07
Abstract: <PICT:0352419/III/1> A process for manufacturing artificial piezo-electric crystals consists in depositing a multiplicity of hemihedral crystals of dielectric substance from a liquid or orienting a multiplicity of minute piezo-electric crystals contained in a solidifying liquid medium, under the combined influence of an electric field and alternating mechanical stresses of high frequency. In one method the liquid 4 in a bath 5 has supersonic vibrations imparted to it from a piezo-crystal 2 connected between the plate and grid of an oscillating valve 6 and actuating a membrane 3 in contact with the liquid, and the plates 8 produce in the liquid a direct electric field perpendicular to the direction of the mechanical vibrations from the source 9 upon which is superimposed an alternating component of the same frequency as the mechanical vibrations by completing the circuit through an inductive coupling 7 to the tuned plate circuit of the valve 6.  The phase relationship between the mechanical and electrical oscillators may be varied by varying the coupling 7, and said oscillations are preferably co-phasal or 180 DEG  out of phase.  The walls of the bath are preferably constructed of or covered with sound-absorbing material in order to restrict the supersonic vibrations to the bath and prevent undesirable acoustic reflections in the bath. Specification 311,055, [Class 32, Distilling &c.], is referred to.

Title: Electric communication transmission system employing filters
IPC: H04M11/06
Filed: 1930-04-09
Abstract: 352,097. Two-way terminal equipment. STANDARD TELEPHONES & CABLES, Ltd. and SANDEMAN, E. K., Columbia House, Aldwych, London. April 9, 1930, No. 11303. [Class 40 (iv).] In a cable system in which the transmitting and receiving circuits are connected to the cable over filters, a common filter is provided in addition to filters individual to the receiving and transmitting branches. The impedance of the transmitting and common filters is matched to that of the cable whilst the receiving filter presents a high impedance to currents received over the cable or alternatively all the filters can be matched to the cable, the receiving amplifier being adjusted to introduce large reflection. In the former case air-cored inductance coils are used in the transmitting and common filters whilst cores of magnetic material are used in the receiving filter. A telegraph channel may be connected to the cable. In the Figure the transmitted signals are connected through amplifier T1, transmission filter F3 and common filter F1 to the cable C whilst received signals pass to the receiving circuit through common filter F1, receiving filter F4 and receiving amplifier R1. The telegraph apparatus TG is connected via filter F5. The filter F4, which may comprise inductance coils having cores of compressed magnetic dust, offers a high impedance to the cable and thus steps up the received voltage. The impedance of amplifier R1 is matched to F4 thus reducing the noise caused by thermal agitation in the cable.

Patent GB-114853-A (GB)
IPC: H05B6/20
Abstract: 114,853. Foley, C. B. April 13, 1916. Induction furnaces.-A core limb 31, Fig. 9, is placed in a passage 20, situated relatively to the bottom of a crucible so that the intervening channel 22 for molten material widens from the bottom upwards, the narrowest part of the channel being in the plane of the core. The walls of the passage and the crucible bottom may have different axes of curvature. Convection is thus assisted, and the pressure due to the head of liquid at the lowest point may be equal to the maximurn " pinch effect " pressure at that point, while, at other depths, the former pressure is the greater. Two or more parallel core passages may be arranged so that the horizontal distance between them is greater than that between a passage and the wall of the crucible. Each core winding may then be connected to a reversing switch so that the currents around the passages may be in the same or opposite directions; in the former case there is little or no heating between the cores. The switches may be arranged so that one or more cores may be put out of action. The single core shown is built up from U-shaped plates forming two horizontal limbs and one vertical one, the remaining limb 29, Fig. 4, being removably supported between the horizontal limbs 32 by insulating tubes 33 surrounding bolts 30 which secure together the plates forming the removable limb. The crucible may have a wide mouth, as shown by the outer dotted lines in Fig. 9, or, for melting volatile or oxidizable metals, such as steel, zinc, or alloys of copper, zinc, antimony, or lead, may have a contracted mouth as shown in full lines. The metal casing shown is split at the bottom; it may be omitted.
