Abstract: 1509742 Curing unsaturated polyesters BERGER JENSON & NICHOLSON Ltd 29 April 1975 [29 April 1974] 17877/75 Heading C3P A process for curing moulding materials based on unsaturated polyester resins and unsaturated monomers copolymerizable therewith, is characterized in that an initiator-catalyst system is employed which consists, relative to 100g. of a 66% by weight solution of an unsaturated polyester resin in copolymerizable monomers, of (a) 0À05-0À5% by weight of "cold-curing" peroxides, (b) 0À025-1À5% by weight of "hot-curing" peroxides, and (c) 0À05-0À5% by weight of one or more compounds of divalent cobalt (calculated as a solution of 1% metal contents) soluble in the polyester resin or in the monomers and in that the polymerization is additionally initiated over at least a part of the gelling time, by exposure to radiation having a wavelength of at least 1Ám. "Cold curing" peroxides initiate polymerization at room temperature and "hot curing" peroxides is defined as those peroxides of which the half-life at 60-130‹ C. is 3-5 hours. The polymerizable polyester material used in the specific examples is formed from phthalic anhydride, maleic anhydride, adipic acid and propylene glycol dissolved in either styrene or a mixture of styrene and methacrylic acid methyl ester. Specific combinations of peroxide catalyst used are methyl ethyl ketone peroxide ("cold") and either cyclohexane peroxide or 3,5,5-trimethylcyclohexanone perketal ("hot"); or methyl isobutyl ketone peroxide ("cold") and cyclohexanone peroxide ("hot").

Abstract: 224,932. Lanchester, F. W. July 19, 1923. Controlling apparatus, arrangements of hand, foot, and transmission gear in conjunction therewith. - Relates to brake mechanism such as described in Specification 133,156, [Class 103 (i). Brakes &c.], and comprising two or more expanding rings or bands each of which engages the adjacent one so as to produce a cumulative effect with either direction of rotation of the brake drum and consists in effecting the expansion of the primary band by a floating wedge member of known kind. As applied to brakes for vehicle steering wheels the wedge member is formed on a link which engages a spherical seating disposed eccentrically in the spherical end of a rock shaft, this spherical head being seated in a fixed spherical socket disposed in line with the steering pivot. Or the wedge member may engage a thrust rod passing through the steering pivot and actuated by screw-and-nut mechanism. Figs. 1 & 2 show one form of vehicle steering wheel brake. The rock shaft f has a spherical head e seated in a spherical socket a formed on the brake cover plate b. A spherical: headed or dumb-bell shaped link h has one end in engagement with the inclined ends m of an expanding brake ring j and the other end seated in a recess formed eccentrically in the head e of the shaft f. When by rocking this shaft, the ring j is expanded into engagement with, and is carried round through a small angle by, the drum n, a projection p on this ring engages one or other of the ends of a second ring q according to the direction of rotation of the drum. The other end of the ring q abuts against a stop r and this ring is thus also expanded. When the brake is released the rings j, q contract into engagement with a drum b<1> on the cover plate b. The brake ring q may, through a floating lug, engage and effect the expansion of a third ring. Fig. 3 shows a front wheel brake in which the wedge-member h has a spherical socket v engaged by a thrustrod u passing through the steering pivot and actuated by a nut w with actuating arm x engaging a fixed screw w<1>.

A closed circuit respiratory apparatus includes a warning device for warning the user when the nutrient gas supply is less than a predetermined value. The warning device comprises a spring bellows 12 in which is displaceably mounted driving member 17 which, under the action of spring 18, tends to extend the bellows 12. The member 17 is articulated to lever 19 which carries flap 20, movable from an open to a closed position, in which it blocks inhalation duct 21. The respiratory apparatus comprises a lung-controlled valve comprising control lever 5 bearing against diaphragm 3, and rockable valve closure member 6 adapted to close oxygen supply pipe 7. On inhalation, the diaphragm causes levers to rock and the valve 6 opens, allowing oxygen to flow to duct 21. Oxygen also flows through throttled screw connection 9 to chamber 11, which holds bellows 12. If the oxygen pressures drops too low, the action of spring 18 overcomes the oxygen pressure and the bellows 12 extend, causing flap 20 to close inhalation duct 21. Flap 20 may be provided with apertures provided with reeds, which result in a warning sound being given when the flap 20 closes duct 21. The gas pressure may act on the inside of the bellows. A throttle may be provided in connection 9.
