Title: Improvements in the manufacture of cellular polyurethanes
Inventor: IBBOTSON ARTHUR
IPC: C08G18/66
Filed: 1962-10-31
Abstract: Foamed polyurethanes may be prepared by reacting an organic polyisocyanate and a polyether containing at least two ether groups and two hydroxy groups per molecule, under such conditions that a foam forming gas is generated, and having in the reaction mixture an N-substituted dialkanolamine in an amount of at least 15% by weight of the polyether.  The preferred polyethers are polymers and copolymers of ethylene oxide or propylene oxide, optionally prepared by polymerization in the presence of a substance having two or more active hydrogen atoms per molecule, such as ammonia and polydroxy compounds such as glycerol, triethanolamine and polyamines such as ethylene diamine and tolylene diamine. Other alkylene oxides may be used such as 1:2 butylene oxide and 2:3 butylene oxide. Many aliphatic and aromatic diisocyanates are listed as suitable polyisocyanates such as hexamethylene diisocyanate and tolylene 2:4-diisocyanate. Triisocyanate may also be used such as 2:4:6-triisocyanateotoluene.  The foam forming gas may be generated by adding water to the reaction mixture to react with a proportion of the diisocyanate to produce carbon dioxide, or by incorporating a low boiling liquid having a boiling point not exceeding 75 DEG  C. which will volatilize on heating.  A combination of these two methods may be employed.  Preferred low boiling liquids are halogenated alkanes containing fluorine, such as monofluorotrichloromethane, dibromodifluoromethane, 1:1:1 - trichloro - 2:2:2 - trifluoroethane, dichlorodifluoromethane, dichloromonofluoromethane, dichlorotetrafluoroethane, monochlorodifluoromethane, trifluoroethylbromide and mixtures thereof.  Examples of suitable N-substituted dialkanolamines include N - methyl diethanolamine, N - ethyldiethanolamine, N-butyl diethanolamine, N-phenyldiethanolamine and N-methyl diisopropanolamine. Other additives which may be included are catalysts such as tertiary amines and soluble organic compounds of heavy metals such as iron and manganese acetyl acetonate, lead actoate, dibutyl tin dilaurate and stannous octoate, surface active agents, e.g. oxethylated phenols, oleyl alcohol, sulphated methyl oleate, polyalkyl or polaryl siloxanes and siloxane-oxyalkylene copolymers, flame retardants such as b -trichloroethylphosphate and dioctylphthalate, colouring matters and fillers such as carbon black and silica and colour stabilizers, whitening agents, and anti-oxidants such as tert-butylalcohol and sterically hindered phenols.

Title: Apparatus for producing fibrous material
IPC: C01G23/07
Filed: 1966-09-21
Abstract: 1,136,228. Glass fibres. JOHNS-MANVILLE CORP. 21 Sept., 1966 [7 Oct., 1965], No. 42058/66. Heading C1M. In a process for controlling glass fibre diameter in a centrifugal attenuation system, the rotor and attenuating means are adjustable relative to each other. A rotor 12, main driveshaft 13, and an interior column 14, through which molten glass from a supply 15 is delivered to the said rotor all surrounded by combustion housing 11, with apertures 28 for attenuating gases. The shaft 13 is mounted in a tube 35, and extending from the lowermost end of shaft 13 is an inner shaft 40 which is concentric with the main shaft and which has keys which allow the inner shaft to be moved relative to the main shaft whilst the two shafts are rotating together. The apparatus includes a mechanism to enable the inner shaft 40 to move in a direction generally parallel to the axis of rotation of the shafts. In operation molten glass is deposited on to the rotor and urged outwardly by centrifugal force through openings 80 in the peripheral wall 81 to form filaments of molten glass which are contacted by a hot gaseous blast from the aperture 28, said blast moving in a direction transverse to the movement of the filaments. If the fibres being produced are too coarse the inner shaft 40 can be moved so as to decrease the distance between the filaments and the attenuating means, the filaments then entering the hot gaseous blast at an area of higher temperature and higher velocity. Conversely if the fibres are too fine the rotor can be moved away from the attenuating means.

Apparatus for making shell moulds comprises a container 1 for moulding material having two or more openings to which heated patterns 17, 28 can be attached, the container being rotatable about an axis 2 so that material falls on to one plate while falling off another. Material is blown periodically into the container from a hopper-filled container 21 through a pipe 23 and an opening 3 which may be coaxial with the axis 2. In operation, two pattern plates 17, 28 are heated under hoods 25, 26. The heated plate 17 is conveyed to a lifting device 13, having fluid-pressure operating means 9, 10, and is pulled against the container 1. A shutter 4 is then opened by fluid-pressure means 15 and material falls on to the heated plate through a sieve 6. The container is rotated, the shutter 4 is closed, the plate 17 is lifted clear of the container, and a lifting device 12 picks up the plate 28 which, being smaller, is held against a reduced opening 14. The plate 17 is then heated under a hood 27 while material is deposited on the plate 28. When next the container is rotated, the plate 17 is moved under the hood 26 for curing. A third plate may be introduced into the cycle from a station at 90 degrees. The plates may have built-in heating means and may be brought into position on a rotating table.

Abstract: 1467748 Metal vapour lamps; luminescent screens PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Oct 1975 [27 Nov 1974] 43797/75 Heading H1D A liquid cooled high pressure metal vapour discharge lamp comprises discharge tube 3 (e.g. of quartz) surrounded by a cooling jacket formed by a tubular envelope with inlet and outlet apertures 5, 6 and containing a cylindrical apertured mirror on the inside of the envelope. The lamp may be used for photographic production of colour T.V. c.r.t. display screens such as for c.r.t.'s with three in-line guns, phosphor strip screens with light absorbing strips, and a colour selection electrode with elongated apertures. Reflected light rays are filtered several times, so the lamp radiates little thermal energy and will not deform a c.r.t. shadow mask by heating. Also reflections at the end faces of aperture(s) in the mirror are avoided. The desired light distribution is obtained as a result of the shape of the aperture(s), which may be rectangular, or other geometries as in Figs. 3a- 3d (not shown). An exposure apparatus is described w.r.t., Fig. 4 and elongate aperture 9 is sufficiently long that shadows on bridges 14 in the mask are not formed on the phosphor screen. Reflective metal layer 8 may be #5 Ám., and quartz envelope 4 may be formed by 0-rings to tube 3.

Abstract: 1,048,682. Automatic control of inductive loads. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 24, 1964 [Nov. 23, 1962], No. 44353/62. Heading G3R. [Also in Division H2] The current in or voltage across an inductive load is maintained in direct proportion to an input signal voltage by connecting the load in series with silicon controlled rectifiers across a D.C. source, the rectifiers being controlled sequentially by a pulse generator whose output is adjustable in mark-space ratio or frequency in accordance with the difference between the input signal and feedback signal from the load circuit. The inductive load may be consitututed by each phase winding of an induction motor regulated by signals whose frequency and phase relation are determined by the difference between an error signal and the slip frequency of the motor so that the motor torque is proportional to the error signal. In the case of a synchronous motor having two phase windings, the pulse generator is controlled, in addition to the feedback, by signals from a resolver driven by the motor through differential gearing which also receives a mechanical rotational error signal. The resolver outputs are thereby phase displaced relative to the motor flux and the energization of the motor windings is varied to produce a torque proportional to the error. When the inductive load is constituted by the field or armature of a D.C. motor or generator, the winding is split, the parts being inductively coupled together. Each part is in series with a separate rectifier, the two rectifiers being operated alternately.
