Title: Production of terpolymers
IPC: C08F220/42
Filed: 1954-12-07
Abstract: Clear terpolymers of (a) styrene, vinyl toluene or vinyl xylene, (b) an alkyl methacrylate, and (c) acrylic acid, methacrylic acid, a monoalkyl or dialkyl fumarate, or a monoalkyl maleate are prepared by a free-radical initiated batch polymerization, to at least a 20 per cent conversion, of a monomer mixture selected from the area that gives clear terpolymers lying on or about (i.e. within 5 per cent of) the line joining the polymerization azeotrope composition of (a) and (b) to the polymerization azeotrope composition of (a) and (c) as plotted on an equilateral triangular co-ordinate graph.  The polymerization azeotrope compositions are those which give interpolymers containing the same relative proportions as the initial monomer mixtures.  The alkyl groups referred to may be methyl, ethyl, n-propyl, iso-propyl, n-, sec.- and tert.-butyl. In examples, mixtures of vinyl toluene, methyl methacrylate and acrylic acid, and vinyl xylene, methyl methacrylate and diethyl fumarate are polymerized by heating in three stages.  Graphs are given.  The polymerization may be carried out in mass, in suspension in water using suspending agents, such as tricalcium phosphate and carboxymethylcellulose (which may yield pearls), or in emulsion using a redox-catalyst and an emulsifying agent such as a salt of a sulphonated long-chain alkyl aromatic compound or a condensation product of ethylene oxide and a long chain aliphatic alcohol or mercaptan.  The term batch polymerization includes the addition of the monomers in fixed proportion to a continuous system, e.g. a series of vessels.  Catalysts mentioned are hydrogen, benzoyl, di-t.-butyl, and diacetyl peroxides; t.-butyl and cumene hydroperoxides; diethyl peroxycarbonate, potassium persulphate and perborate; a ,a 1 - azodiisobutyronitrile, p - bromobenzenediazonium fluorborate, N-nitroso-p-bromoacetanilide, azomethane, phenyldiazonium halides, diazoaminobenzene, p-bromobenzenediazonium hydroxide and p-tolyldiazoaminobenzene.  Heat alone or ultraviolet light, if desired in the presence of a photosensitizer such as an organic disulphide, may also be used.

Title: Improvements in or relating to heating and cooling systems
IPC: G05D23/13
Filed: 1961-10-04
Abstract: 1,004,698. Temperature responsive elements. M. CLAUSEN [trading as firm of DANFOSS VED ING. M. CLAUSEN]. Oct. 4,1961 [Oct. 5,1960], No. 35810/61. Heading G1D. [Also in Divisions F2 and F4] In a heating and cooling system, a heat exchanger (not shown) is supplied through one flow pipe, with heating fluid or through another flow pipe with cooling fluid as necessary, under the control of a thermostatic valve unit 1. The heat exchanger may for example be located in a room the temperature of which is to be controlled. The valve unit shown comprises two valves 5, 7 separately actuated by bellows 23, 24 respectively located in interconnected chambers 21, 22 containing the operating fluid and connected to a feeler probe 25 located in the room. The valve chambers 2, 3 connect with a common port (shown diagrammatically at 10) leading to the heat exchanger. Chamber 2 is connected with a flow pipe 8 for cooling medium and chamber 3 with a flow pipe 9 for heating medium. Simultaneous adjustment of the valves is by a screw 14, or other device which moves a cross-bar 15 to alter the tension of springs 16, 17. When the room is at the desired temperature both valves are closed. Should this temperature rise, the consequent increase in vapour pressure in the chambers 21, 22 tends to compress both bellows 23,24 but the construction is such that only the valve 5 can open thus permitting flow of coolant from the pipe 8 to the port 10 and to the heat exchanger (as in the position shown), until the room temperature falls sufficiently to allow valve 5 to close. When the room temperature falls below the desired value, the vapour pressure in the chambers 21, 22 is reduced but the arrangement then allows only the bellows 24 to expand with consequent opening of valve 7 to allow heating fluid to flow from pipe 8 to the port 10.

Class 98(1) In a camera for use with a paper-backed film having a paper leading strip 1a, there is provided film metering mechanism comprising a roller 9 in driven contact with the film 1, a peripherally notched disc 14 with a member 18 bearing against its periphery to lock the film feed by engaging in a notch in the disc, an exposure counter wheel (not shown) mounted to rotate with the disc, disengageable gearing 10, 11, 12 operable to drive the notched disc from the metering roller, latch means including a stationary abutment 27 on the camera housing and a lever 23 having one arm 25 urged to engage the abutment to hold the gearing disengaged and another arm 24 extending into the path of the film to allow free passage of the leader strip but to be actuated by the thickened portion 1b formed by the junction of the light-sensitive and backing strips, to release the latching lever from the stationary abutment and means operative upon the release of sa:d latch to move the disengageable gearing into driving relation with the notched disc. As shown, when the junction of the backing paper and light-sensitive film rocks the lever 23 clockwise, releasing the notch 26 from the abutment 27, a spring 20 rotates clockwise a plate 15 pivoted on the axis of gear 11 and carrying the lever 23 and gear 12 to move this gear into mesh with a gear 13 fast with the disc 14. Further movement of the film thus rotates the notched disc 14 until a projection 39 on the end of the lever 18 falls into the first notch when the pawl end 8 of the lever engages a ratchet wheel 7 on the driven shaft of the take-up spool 6 to arrest the film ready for the first exposure. On actuation of the shutter the disc 14 and ratchet wheel 7 are released by known means (not shown) from the lever 18 to allow further feeding of the film. On finishing a roll of film, the camera is opened and a slide 31 on pin-and-slot guides is urged outwardly by a spring 34 whereupon a projection 36 on the slide engages a projection 37 on the lever 23 and rotates it and the plate 15 to disengage the gear 12 from the gear 13 and to reengage the latch 26, 27 to hold the gear 12 disengaged. Simultaneously the inner end of a slot 38 in the slide moves the projection 39 on the lever 18 clear of the disc 14 so that a spring (not shown) returns the gear 13 and disc 14 to the zero position and frees the take-up spool ratchet wheel 7. On closing the camera the slide 31 is returned to the position shown without affecting the lever 23 and plate 15. For initial setting adjustments, the fixed abutment 27 is formed on a pivoted lever 28 provided with a locking screw 30.

Title: Process for Positioning a Wire along a Helical Path on a Cylindrical Fuel Element.
Inventor: BRARD JEAN-CLAUDE
IPC: G21C3/338
Filed: 1968-07-29
Abstract: 1,186,321. Coiling helices. COMMISSARIAT A L'ENERGIE ATOMIQUE. 29 July, 1968 [28 July, 1967], No. 36048/68. Heading B3E. [Also in Division G6] A fuel element consisting of a cylindrical can filled with fuel material and closed by two plugs is provided with a helically wound wire for the purpose of providing precise spacing of the element from adjacent elements in a bundle, by forming at least one of the plugs 12 as a can obturator 20 with an end member 22 rotatable by means of a cylindrical stud 24 engaging with an easy fit in a blind hole 26 formed in the obturator 20 coaxially with the can 10. The ends of a suitable length of wire 16 are secured as by brazing to the end member 22 and to the other plug 14, and the end member 22 and can 10 are rotated relative to each other while guiding the wire 16 round the can. When the wire 16 has been positioned in a helix and tensioned, the end member 22 is secured to the obturator 20 by welds. In the fuel element illustrated, the upper plug 14 is in one piece and the upper end of the wire 16 is brazed on to a ring 18 welded into a recess in the plug 14. The lower end of the wire 16 is engaged in an orifice in the end member 22 of the lower plug 12 and is fixed to this plug by brazing. The wire 16 may be guided round the can 10 by means of a tubular chaser (Fig. 2, not shown), with an internal guide groove having a pitch corresponding to that desired for the wire 16. The chaser is threaded on to the end of the can 10 near the upper plug 14 and the end member 22 then rotated while the can 10 is held stationary. The chaser which is moved axially by a mechanism synchronized with the rotation of the end member 22 is allowed to rotate freely and thus follow a helical path. Another form of guide (Fig. 4, not shown), comprises a spigot having a guide groove which is urged by a spring against the wire 16, the guide being moved axially in synchronism with the rotation of the can 10 the end member 22 being held stationary in this case. The guide is prevented from rotating around the can axis. If the element is very long with a large number of turns of wire, a constant tension of the wire over the entire length of the element may be obtained by forming both plugs in two parts as is the plug 12 described above, the two end members 22 being rotated in opposite directions while the can 10 is held stationary, and by using two half-chasers moved synchronously in opposite direction, starting from the centre of the can.
