Title: Process for preparing trialkyl phosphites
Inventor: SCHERER OTTO
IPC: C07F9/142
Filed: 1964-03-24
Abstract: Trialkyl phosphites are obtained by reacting a saturated aliphatic monohydric alcohol containing 1 to 9 carbon atoms with a phosphorus trihalide in an amount of more than 2 moles per mol. of phosphorus trihalide in the presence of a diluent and an ammoniated water-soluble salt of an element of Group II of the Periodic Table in an amount sufficient to maintain a pH of at least 7 in the reaction mixture during and after the reaction at a temperature in the range from about -5 DEG  C. to +10 DEG  C.  The process may be carried out by adding the ammoniated water-soluble salt to a mixture of the saturated aliphatic monohydric alcohol and a diluent in such an amount, that the proportion of ammonia contained in the said salt is at least 110% of the stoichiometric amount required for binding the hydrogen halide formed.  The mixture obtained is then reacted with phosphorus trihalide. Alternatively, a smaller amount of the ammoniated water-soluble salt can be added to the mixture of the saturated aliphatic monohydric alcohol and the diluent, and during the reaction ammonia is introduced to reform the ammoniated salt.  A further variant consists in adding a water-soluble salt, capable of being ammoniated, of an element of Group II of the Periodic Table to the mixture of the saturated aliphatic monohydric alcohol and the diluent, then introducing ammonia so that the salt is wholly or partially converted into the ammoniated compound, and then reacting with the phosphorus trihalide.  When working in this manner ammonia is added until the pH of the reaction mixture is above 7.  Suitable saturated aliphatic monohydric alcohols include primary and secondary alcohols such as methanol, ethanol, propanol-(1), propanol-(2), n-butanol-(1), n-butanol-(2), n-pentanol-(1), n-pentanol-(2), n-octanol-(1), 2-ethyl-hexanol-(1) either alone or in admixture with one another.  Suitable phosphorus halides are phosphorus trichloride and tribromide. Larger quantities of alcohol may be used as a diluent.  Suitable ammoniated compounds are the ammonia-addition compounds of water-soluble, dry or water-containing salts of Mg, Ca, Sr, Ba, Zn and/or Cd, capable of adding 1 to 8 mols. of ammonia. Suitable diluents include ethers, halogenated alkanes, aliphatic or cycloaliphatic hydrocarbons including phenyl cyclohexane. Examples are given for the preparation of trimethyl phosphite, triethyl phosphite and tributyl phosphite using phosphorus trichloride or phosphorus tribromide as the phosphorus halide in the presence of ammoniated calcium chloride; and of trimethyl phosphite using phosphorus trichloride in the presence of zinc tetramine chloride.

Title: Nuclear reactor
IPC: G21C3/322
Filed: 1974-03-20
Abstract: 1463532 Nuclear reactors SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES ALSTHOM 20 March 1974 [22 March 1973] 12474/74 Heading G6C In a nuclear reactor cooled by a liquid, fuel elements are carried by a support plate which has recesses each accommodating the foot of a respective fuel element, the foot defining an internal flow passage for the liquid and having a region of reduced cross-sectional flow area, this region being in communication with the space between the foot and the wall of the associated recess at a position downstream of a labyrinth seal acting between the foot and the wall. Thus, any leakage coolant in the space can enter the foot by virtue of the reduced static pressure in the region of reduced flow area. In one embodiment (Fig. 1) the foot 3 is centred in the recess 2 of support plate 1 by partspherical protuberances 5; intermediate its length, the foot 3 affords seals 8, 13 for reducing leakage flow in the space 12. Downstream of the seal 8, orifices 11 connect the space 12 with the flow channel within the foot 3 in the region of a narrowed portion 10 of the channel. By conducting leakage flow from space 12 into the flow channel in the foot, leakage flow past the protuberances 5 is minimized. Pressure in space 12 is maintained higher than in space 15 above support plate 1 so as to preclude reverse leakage past protuberances 5. The effects of this pressure differential are minimized by the further seal 13. In a second embodiment (Fig. 2) the foot is centred by means of an annular rib 16 which also acts as a seal; the further labyrinth seal is dispensed with. In a third embodiment (not shown), similar to that of Fig. 2, the further labyrinth seal, such as is provided in the embodiment of Fig. 1, is included. In a fourth embodiment (Fig. 4) the crosssectional flow area of the channel within the foot is reduced by means of an internal structure comprising diaphragms 18. The orifices 11 are provided in the vicinity of one such diaphragm. Levitation of the fuel element by the coolant pressure is minimized by providing for lateral entry of coolant to the foot via apertures 14, 19.

Abstract: 466,683. Projectile fuzes. GIRARD, P. May 2, 1936, No. 12506. Convention date, May 3, 1935. [Class 9 (i)] Relates to clockwork fuzes in which the release of a firing-pin is controlled by a timing disc set in one direction before firing and rotated back during flight. According to the invention, two timing discs d, k are provided rotating in opposite directions at different relative speeds. As shown, one disc k is keyed to the shaft e of the clockwork, and the other disc d is formed with an internal toothed crown m and driven through a planet pinion c by a pinion h keyed to the shaft e. Notches i, j in the discs are normally in line with each other opposite a finger p on one arm of a lever f pivoted at o; and the other arm of the lever engages a notch q in the firing-pin r and below a flange u on a safety bolt g. When the clockwork is wound and set, the notches i, move in opposite directions at different speeds, the finger p is wedged away from these notches, and this causes the other arm of the lever f to release the flange u. On discharge, the bolt g sets back, leaving. the lever f free. At the appointed time, the notches i, j are returned by the clockwork into coincidence opposite the finger p, and the lever is swung round by a spring t to release the firing-pin.

Filed: 1973-03-16
Abstract: 1412678 Magnetic levitation E BREITBACH 16 March 1973 [20 March 1972] 12735/73 Heading H2A [Also in Division H4] A device for the detection of solid-borne vibrations comprises a pot-shaped stator 1 (Fig. 2) for receiving the vibrations. An upright 2 supports a magnet 3. A cylindrical oscillatory member 3 coaxial within the stator 1 is vibratable in the direction of the stator axis and encircles magnet 3 and support 2 without touching them. Oscillatory member 7 carries two annular magnets 9, 10. Magnet 3 is disposed coaxially with a magnet 8 and these two magnets are magnetized in opposite senses so that magnet 3 supports magnet 8 together with the oscillatory member 7. Annular magnets 9, 10 cooperate with concentric annular magnets 6, 5 mounted on the stator 1. The magnets 5, 6, 9, 10 are magnetized radially and, since like poles confront, they act to centre and axially guide the oscillatory member 7. At least one magnet or one of the magnet pairs 3 and 8, 5 and 10, 6 and 9 may be an electromagnet, preferably that or those connected to the stator 1. This enables the characteristics, such as the natural frequency of the device, to be varied. The magnets of the stator and/or the oscillatory member 7 may be interconnected by magnetically soft material for optimum utilization of stored magnetic energy. By making the diameter of one of the two magnets 3, 8 (preferably 8) greater than the other, or by convexity of the polar surfaces, in the event of horizontal displacement the horizontal forces between magnets 3 and 8 can be made negligible.

[Class 106 (ii).] In brake-testing apparatus in which the braked wheel of a vehicle rests on rollers driven by a motor, and a force proportional to the torque of the motor displaces a pivoted arm a against a spring in casing c, thus operating a pointer moving over a scale, a piston j working in a cylinder e filled with oil or other liquid is attached to the arm a to damp out rapid oscilla. tions of the system. The piston is a loose fit in the cylinder to allow oil to pass it at a fixed rate and thus permit general movement of the arm. Holes k may be provided in addition in the piston to aid this effect. The piston consists of a disc having a peripheral flange in the form of a central band of a hollow sphere or having its rim turned to a spherical radius to permit the piston to rock within the cylinder. The piston-rod f is furnished with a slot l surrounding a pin n connected to the arm a and provided with opposed flats so that in one position the pin is locked in the enlarged lower end of slot l, and on rotation through a right-angle it slides freely in the slot rendering the damping mechanism inoperative.

Abstract: 1371921 Dispensing measured quantities of liquid BARBER ELECTRICAL SERVICES Ltd 24 April 1972 [4 May 1971] 12860/71 Heading B8N [Also in Division G4] A machine for dispensing measured quantities of liquid comprises a vented sight glass 9 connected to an optic measure 10, a liquid container 2 connected via pipe 7 with the sight,glass, a displaceable support 26 for a glass, and means, for actuating the optic measure, driven by an electric motor 23 that is brought into operation by a circuit closed both by displacement of the support and the operation of a coin-receiving mechanism, or solely by displacement of the support, the conditioning of the machine to operate in either of these ways being effected by the setting of a control switch 49. As illustrated the machine includes two liquid containers 2 each communicating with a respective sight glass 9 and optic measure 10 via a tap 5, and two electric motors 23 each effecting via a cam 21a and pivoted lever arrangement 19-21, operation of the respective measure 10. With the switch 49 switched to "coin operation", replacing a removable door and turning key operated switch 39 will actuate a solenoid 43 to unblock slot 35 so that coins can be inserted into mechanism 41 which incorporates devices for checking the diameter, thickness and weight of a coin and for detecting washers or discs of ferous metals. A glass is positioned on one of the pads 26 prior to coin insertion, and tilting of the platform 24 causes lever 28 to operate the appropriate microswitch 31. A certain number of coins, e.g. three are then inserted and the final coin operates micro-switch 45 to energize a first relay (not shown) which energization together with the operated switch 31 starts the motor associated with the selected container. Actuation of a micro-switch 50 by lever 19 closes a holding circuit for the energized motor and deenergizes the first relay. The motor continues to operate until switch 50 is opened i.e. by cam follower 21 being received in recess 21b of the cam 21a. In a "non-coin operation", energization of the motors is effected solely by operating one of the switches 31 by placing a glass on one of the pads 26. When one of the containers is empty a float 11 in sight glass 9 interrupts a light beam to photo-electric cells 12 so as to condition a circuit to illuminate a "sold-out" legend 14 and to prevent unblocking of the coin slot 35. Lamps 32 illuminate the optic measures 10 and depression of a button 37 will effect return to a hopper behind flap 38 of rejected coins.
