The composition may also contain transition metal compounds such as Fe acetate, Fe formate, Fe stearate, Fe oleate, Fe naphthenate, Fe acetylacetonate, Co acetylacetonate, Mn acetate, Mn oxalate, Mn oleate, Mn stearate, Mn acetylacetonate, Cu acetate, Cu oxalate, Cu octanoate, Cu oleate, Cu stearate or Cu acetylacetonate. A brominated aliphatic hydrocarbon may also be present, many examples being given. Exemplified compounds (b) are benzophenones of general formula wherein R 1-6  are as defined above, fluorenones of general formula wherein R 1-6  are as defined, xanthones of formula wherein R 1-6  are as defined, phenylalkyl ketones of formula wherein R 1-3  are as defined, and phenylhaloalkyl ketones of formula wherein X 1-3  are H or halogen. In the examples polystyrene is mixed with the following specific (b) compounds: benzophenone, and its 4-bromo, 4-methyl, 4,4<SP>1</SP>-dimethoxy derivatives, fluorenone, xanthone, 2-chloroxanthone, acetophenone and its 3-bromo, 4-bromo, 2-methyl-4- chloro, 3-methyl-4-chloro, 3-methyl-4-bromo, 2,4-dichloro, 4-hydroxy, 3-methyl-4-hydroxy, 2,5 - dimethyl - 4 - hydroxy, 2 - nitro, 3 - nitro- 4 - methyl, 3,5 - dinitro, alpha - bromo, alphachloro, alpha - bromo - 4 - bromo and alphabromo-4-chloro derivatives, propiophenone and butyrophenone with or without one of the specified metal compounds and/or brominated hydrocarbons; and styrene/butadiene copolymer is mixed with benzophenone, and acetonphenone with or without one of the metal compounds and/or brominated hydrocarbons. In Example 3, styrene is suspension polymerized in the presence of benzophenone, and the resulting beads autoclaved with pentane to produce foamable beads which are moulded and a foamed sheet produced. The compounds (b) render articles made from the polymers photodegradable, i.e. on exposure to sunlight or U.V., they gradually decompose (depolymerize).

Title: A process of telephony and telegraphy by high frequency currents and stationary periodicity transformers
IPC: H03C1/10
Filed: 1920-10-26
Abstract: 154,885. Ges. f³r Drahtlose Telegraphie. Dec. 2, 1919, [Convention date]. Frequency, changing.-In a system for telephony and telegraphy with high-frequency currents and stationary frequency converters, of which the self-induction is varied by a telephone or a key, a capacity is arranged in parallel with the primary side of that portion of the converter which is at a high degree of saturation, the value of the capacity being such that a small variation of the means which serve to vary the self-induction causes a great variation of the self-induction with stable ter@ion relations of the converter. The self-induction may be varied, for signalling, by means of a microphone or key in the circuit of the direct current excitation. Fig. 7 shows the application to a converter for trebling the frequency, in which the capacity C is connected in parallel with the saturated winding D1. A series condenser C, may be connected in front of the converter to prevent substantial variations in the tension of the source 1, and may be used for tuning the primary circuit. Alternatively, the converter may be excited by alternating current, and variations in the saturation mav also be caused by altering the number of windings.

Abstract: 1,170,660. Conveying bobbins. GIDDINGS & LEWIS-FRASER Ltd. 2 May, 1968 [1 July, 1967], No. 30472/67. Headings D1F and D1J. A magazine for supplying bobbins to the winders 24 of a travelling roll winder comprises a plurality of removable bobbin-receiving pegs 19, a guide defining a path 17 for the pegs, the path starting in means 27 for transferring a peg from a winder to the path and terminating at means 23 for transferring a peg from the path to a winder, and means 12 for moving pegs between the two transfer means. As shown, the magazine uses arm 23 to supply pegs carrying full packages to a winder, arm 27 to transfer pegs carrying empty bobbin back to the oval path 17 and a chain (15) to move the pegs around the path. The pegs have flanged bases 20 resting on table 10 with pin 19 protruding through a slot in cover 18. The chain (15) runs below the table 10 and engages the pegs with protrusions 16 which extend through slot 11 in table 10, see also Fig. 2 not shown. In operation the chain (15) is driven intermittently from the winder to progress the pegs around the path in the direction of arrow B. An operator places full packages on the pegs and feeds the yarn end into a suction pipe (35). At outlet 22 the arm 23 transfers the peg and package into the path of winder 24. The motion of the winder in the direction of winder C causes the peg to be engaged by arm 24 and cam 25 forces the peg further into the arm 29 so that the peg is engaged by a spring clip. Doffer cam 28 causes the pegs carrying empty bobbins to be disengaged from the winder arm 24 into the path of transfer arm 27.

A collective pitch control lever 12 is pivotally mounted at 13 and formed with a bifurcated extension 16, the forks of which provide a pivotal mounting 17 for a spring loaded telescopic member 18 connected at its free end to a lever 20 which engages a stop 21. A further member 22 of fixed length is connected to extension 16 and also to a stop mechanism 23. This comprises a cranked arm 24 pivoted at 25 to co-operate with adjustable stops 26, 27 which are set to limit the movement of lever 12 between minimum (B) and maximum (C) positive-pitch control settings. When the helicopter has to be operated from a moving platform stop 26 is screwed back to a negative pitch setting (D) so that with arm 20 engaging stop 21, the pilot can, by exerting pressure on lever 12, overcome the spring loading of member 18 and move lever 12 into the negative collective pitch setting.
