Abstract: 1,251,883. Valves. DANFOSS A./S. 16 April, 1969 [19 April, 1968], No. 19477/69. Heading F2V. [Also in Divisions G1 and H1] An actuator for a valve comprises a piston 4 which is displaceable by an electrically heated expansible material 2 and which acts upon a displaceable spindle 5, the piston and spindle being displaceable relatively to each other and a switch in the circuit supplying heating current to the expansible material being actuated in dependence on the relative displacement. The material 2 is heated by a coil 3 connected to supply terminals 24, 26 via switches 18, 21. A control switch 25 is connected in parallel with the switch 18 and an intermediate member 12 is spaced from the piston 4 and the spindle 5 by springs 11 and 13 respectively. A spring 9, which is stronger than spring 11 but weaker than the spring 13, biases a closure member 6 away from the valve seat 7, a flange 8 on the spindle abutting the valve housing 10. With the switch 25 open, the material 2 heats up thus displacing the piston 4 until the switch 18 is open. The heater current is therefore cut off and the valve remains in its open position. With the switch 25 closed, the spindle 5 is displaced against the force of the spring 9 to close the valve. Heating of the material 2 continues until the movement of the member 12 towards the spindle 5 against the force of the spring 13 opens the switch 21. In a modification, Fig. 2 (not shown), an additional switch actuated by the piston and a further control switch enable the valve to occupy open, closed or intermediate positions.

Abstract: 1,256,500. Automatic temperature control  systems. DIAMOND H CONTROLS Ltd. June 6, 1969 [June 28, 1968], No.31050/68. Heading G3R. A three-term retroactive control system comprises a device producing a digital output at a rate proportional to the instantaneous magnitude of the function error; a computer deriving from the digital output a set of three counts significant of a proportional term, a derivative term and an integral term, respectively, of the function; a register into which is periodically transferred the sum of the three counts derived during a time interval preceding the transfer; and means providing, after the transfer, a restoring value determined from the sum transferred to the register at the end of the preceding time interval. Applied to a temperature control system, an analogue to digital coverter 4 produces signals at a rate directly proportional to the output from a sensor 2, e.g. a thermojunction device, which singals are fed to a computer 5, which, during a time interval determined by a sequence unit 20 calculates in stages 9-11 the proportional, differential, and integral terms of the signal and inserts a count equal to the sum into counter 31. The proportional and derivative terms are both reset at the end of each time interval whereas the integral term is not. Manual controls, not shown, enable the relative proportions of the three counts to be adjusted to settings found from experience. At the end of each interval the count in 31 is transferred into a store 51 and during the following interval counter 31 is replenished and a heater 3 is controlled by the value stored in store 51 which sets a six element binary register 52 storing 64 bits of information; 63 bits are used for heater control, the 64th being a checking interval in which a circuit 17 monitors the absence of current in the heater 3, and if current is present an alarm 18 is activated. The store and register 51, 52 receive pulses from a timing generator 15 at the rate of 100 c. p. s. synchronized with zero points of an A. C. supply and a switching element 16 e.g. a triac is arranged to pass only complete cycles determined in number by register 52 so that the number of cycles corresponds to 1, 2, 4, ... 32 cycles or any combination of these numbers. The temperature limits may be fixed or may be varied by a programme arrangement and the reset time of the arrangement may vary with the sum transferred to the register. Further the binary elements may be replaced by a decimal or other code. Conveniently the integral term count is held in a register which is "non-destructive" so that its recorded value is not lost if for example the main supply becomes disconnected. Such a register may comprise a ferrite core memory store or a counter having permanent magnets. Detailed circuits are given in Figs.2 and 3 (not shown) for gating the various components of the system.

Abstract: 1,256,704. Cyclic siloxazanes. MIDLAND SILICONES Ltd. 25 March, 1969 [29 March, 1968], No. 15282/68. Headings C3S and C3T. Novel cyclic siloxazanes containing one or two groups of the formula wherein one of the free valency bonds of each silicon atom is attached to another member of the cyclic structure and the remaining free valency bonds are attached to phenyl or C 1-4  alkyl or alkenyl radicals, are prepared by reacting cyclic siloxazines containing one or two groups of the corresponding formula with an alkyl, alkenyl or aryl compound of lithium in the presence of an organic solvent. The above lithium-containing cyclic siloxazanes may be further reacted with organosilicon compounds containing at least one siliconbonded halogen atom to provide monomers or polymers in which the lithium atom of the starting material is replaced by a silicon atom. Lithium-containing products are preferably typified by those of the formulµ wherein R represents alkyl, alkenyl or phenyl and Z represents hydrogen, lithium, alkyl, aryl, silyl, siloxy or a polysiloxane residue. Subsequent reaction of dilithium compounds with halosilanes of the formula ZR<SP>11</SP> 2 SiCl (wherein Z represents a vinyl radical "Vi" or a dialkylamino radical) yields products typified by those of the formulae wherein "Me" represents a methyl radical. Similarly, reaction with a dihalosiloxane yields polymeric products containing repeating units of the formula wherein R<SP>1</SP> is a monovalent hydrocarbon radical. Uses.-As intermediates and as polymerization catalysts for siloxanes.
