Patent GB-880446-A (GB)
Title: Improvements in and relating to glycidyl derivatives
Filed: 1959-01-30
Abstract: A heat-curable resinous mixture comprises the polyglycidyl derivative of a primary amino phenol wherein the number of glycidyl radicals is equal to at least 80% of the sum of the number of hydroxyl groups and twice the number of amino groups in the parent amino phenol, and a hardener or catalyst for hardening epoxy resins.  Suitable hardeners are polyhydric phenols, such as bisphenol A, 2, 2-bis (parahydroxyphenyl) propane, primary and secondary polyamines, e.g., m-phenylene diamine, 4, 41 methylene dianiline, polyamides, polymercaptans, polycarboxylic acids or anhydrides, e.g. maleic anhydride, endomethylene tetrahydrophthalic anhydride or its alkyl ester.  Suitable catalysts are alkalis, amines, quaternary ammonium compounds, boron trifluoride complexes, e.g. boron trifluoride piperidine complex and boron trifluoride monoethyl amine complex. The polyglycidyl derivatives may be used in combination with other epoxy resins.  The mixing of the glycidyl derivatives and hardeners takes place at temperatures between 25 DEG  C. and 100 DEG  C. and the curing at temperatures from 25 DEG  C. to 200 DEG  C.  In examples, the triglycidyl derivative of p-amino phenol is mixed with (2) the eutectic mixture of m-phenylene diamine and 4, 41-methylene dianiline; (3) the methyl ester of endo-methylenetetrahydrophthalic anhydride; or (4) boron trifluoride-piperidine complex, and the various mixtures are cured.  The epoxy resins may be used for a variety of high temperature applications and may be mixed with glass fibres.ALSO:The invention comprises polyglycidyl derivatives of aromatic primary amino phenols wherein the number of glycidyl radicals is equal to at least 80% of the sum of the number of hydroxyl groups and twice the number of amino groups in the parent amino phenol. Preferred compounds have each hydrogen atom of each phenol group and of each primary amino group replaced by a glycidyl radical, e.g. triglycidyl p-amino phenol.  The novel compounds are made by reacting an amino phenol with an a -haloepoxy compound at a temperature which does not exceed 70 DEG C., e.g. from 25 DEG C. to 45 DEG C., and in the presence of a catalytic amount of lithium compound and dehydrohalogenating the halohydrin thus formed with an alkali, e.g. sodium hydroxide, preferably within the range from 25 DEG C. to 80 DEG C.  Suitable aminophenols are p-aminophenol, 5-amino-1-naphthol, 4-amino resorcinol, 2-methyl-4-amino phenol and 2-chloro-4-aminophenol.  Suitable lithium compounds include the hydroxide, oxide, chloride, bromide, iodide, acetate, propionate, butyrate and naphthenate.  Epichlorohydrin is the preferred halo-epoxy compound.  The polyglycidyl products can be used in the preparation of thermosetting compositions (see Group IV (a)).

Title: Improvements in an automatic clutch
IPC: F16D43/12
Filed: 1934-02-02
Abstract: 434,528. Friction clutches. DEHN, F. B., 103, Kingsway, London.-(Borg & Beck Co. ; 6558, South Menard Avenue, Chicago, U.S.A.) Feb. 2, 1934, No. 3528. [Class 80 (ii)] In a centrifugal friction clutch comprising a driven plate 13 interposed between a driving flywheel 11 and a presser plate 12 rotating with the flywheel, plates 34 and 36 disposed between the plate 12 and a cover 17 secured to the flywheel are urged towards each other and the plate 12 towards the plate 36 by springs 40 encircling shouldered studs 37 and 41 secured to the plates 36 and 12 respectively, the studs being guided in apertures in the cover 17. Springs 35, encircling the springs 40, act between the cover 17 and the plate 34. Two sets of weights 42, 42<1>, which may be formed of laminae secured by rivets 43, have feet 44 which extend through apertures in the plate 34, the toes 45 engaging the plate 34 while the heels 46 of the weights 42 engage the edges of slots in the plate 36 and the heels of the weights 42<1> engage the edges of inserts 47 in the plate 12. Radial levers 26 pivoted on studs 28 adjustably mounted in the cover 17 coact at their inner ends with a control collar 22, while their outer ends engage apertures in a flange 33 formed on the plate 34. There are three weights 42<1>, six weights 42, three studs 41, and twelve studs 37. With the collar 22 held in intermediate position, the clutch functions automatically in two stages. At a predetermined speed, the weights 42<1> move centrifugally outwards and, due to the tilting of the feet 44, move the plate 12 to the left against the action of the three associated springs 40, as shown in Fig. 2, thus producing partial clutch engagement. As the speed increases, the weights 42 come into action to move the plate 36, and with it the plate 12, to the left against the action of the twelve associated springs 40, as shown in Fig. 3, thus producing final clutch engagement, the reaction causing the plate 34 to move slightly to the right against the action of the springs 35 so as to relieve the levers 26 from load. At greater speeds, the weights contact with the flange 33. By moving the collar 22 to the left, however, clutch disengagement at all speeds is effected, while, by moving the collar to the right, the springs 35 effect clutch engagement at all speeds.

The pitch of the corrugations is slightly different from that of the thread of the lamp cap so that a tight connection between the lamp and holder is produced. Further grooves 3 are provided which communicate with apertures in the diaphragm 5 to form ventilating passages. Leads 15 to terminals 11, 18 are gripped between a block 6 projecting from diaphragm 5 and the interior surface of the cover 2.

Title: Appliance for the purification and sterilization of gases in particular room air
IPC: B60H3/00
Filed: 1963-01-24
Abstract: 1,029,621. Air-conditioning units. K. E. MERCKLE. Jan. 24, 1963, No. 37616/63. Heading F4V. [Also in Divisions B1 and B2] An air conditioner comprises a portable casing 14 within which is mounted a cathode element 18 in the form of a cylindrical filter structure constituted by metal filings or threads and connected by a lead 17 to the negative pole of a rectifier 16 fed from a transformer 15. Air to be purified is sucked by a fan 19 and passes through slots 26 in the front of the casing and through a metal filter element 21 which may be connected to the positive pole of the rectifier 16 to serve as an anode filter. The air is directed by a conical deflector 22 through the cathode filter element 18 where the foreign bodies still present in the air are deposited on the element while the purified air becomes sterilized by anions radiated from the cathode element and escapes to atmosphere through a grating 23. Sterilization of the air may be further increased by the addition of ozone which may be produced either separately and fed into the air flow or by setting up an electrostatic field between the fitter elements 18 and 21, the ozone being produced by the passage of the air through the field. Further sterilization may be obtained by locating an ultraviolet light generator and/or radio-active elements outside the casing 14 or inside the casing between or outside the filter elements 18 and 21. The latter may be adapted to serve as a protection against radiation.

[Also in Group XXII] An extrusion apparatus for extruding light metal sections, comprises a container 10 having a liner 12 and disposed between a head plate 28 and a back plate 34, a die 42 secured in the head plate and a screw conveyer 50 extending slidably into the bore of the liner, the working volume of the screw increasing from its inlet end 68, which is fed with particulated metal through a bore 62, to its output end 54. The increase in working volume of the screw is preferably achieved by varying the pitch but alternatively the root diameter or land width of the screw may be changed. The liner bore has a helical groove or rifling 14 of opposite hand to the screw. Grooves 18 in the liner communicate with passages 23 for the circulation of a heating fluid such as hot air or a coolant such as air or an air-water vapour mixture. The extrusion metal 64 may be in powdered or chip form. The screw is supported by a journal 60 with an adjacent packing gland 66 and the thrust is taken by a bearing 58 which may alternatively be a Kingsbury thrust bearing. Cooling water is circulated through the screw by means of a tube 72 extending through a bore 70 in the screw, the water returning along the outside of the tube. The screw is driven by gearing 61. The ratio of the diameter of the screw to the length of the liner should not exceed 1 : 4 but this ratio may be increased if the screw and liner are refrigerated.
