Title: Improvements in methods of and apparatus for regulating the operation of steam and like vapour generators of small liquid content
IPC: F22B35/10
Filed: 1931-02-25
Abstract: 372,003. Feedwater and fuel regulators for steam boilers. SULZER FRERES SOC. ANON., Winterthur, Switzerland. Feb. 25, 1931, No. 5892. Convention date, March. 3, 1930. [Class 123 (ii).] The feed supply and the fuel supply of an instantaneous generator are regulated by a pressure-operated device 12 in the steam pipe 4, and the fuel supply alone is simultaneously regulated by a temperature-operated device 16 in the steam pipe. In addition, the air supply to the furnace may be controlled by one of the devices 12, 16. The furnace may be fired with liquid, gaseous, or solid fuel. A large part of the fuel supply may be controlled by the pressure-operated device and a small part by the temperature-operated device. The levers 18, 19 of the supply and fuel-supply valves 8, 10 are connected to the pressure-operated device by rods 13, 15, and the lever 19 is connected also to the temperature-operated device by a riveted link 14 and a rod 17.
Patent GB-1043356-A (GB)
Title: Purification of bipyridyls
Inventor: BRADBURY FRANK RAYMOND
IPC: C07D213/22
Filed: 1963-02-13
Abstract: Terpyridyl impurity is removed from a bipyridyl by contacting the impure bipyridyl with a substantially water-immiscible organic solvent and an aqueous acid medium containing at least one compound of nickel, cobalt, zinc or iron and thereafter separating the organic solvent phase which contains the pipyridyl. The starting impure bipyridyls may be obtained from a magnesium-pyridine interaction product, e.g. by oxidation.  The substantially water-immiscible organic solvent may be, for example, toluene, benzene, trichloroethylene or perchloroethylene. The aqueous acid medium preferably has a pH value of 5-6 and suitable acids are, for example, hydrochlori and sulphuric acids. In order to maintain the mixture at the required pH it may be necessary to add buffers or alkali. Preferably, the purification is carried out at a temperature of not less than 60 DEG  C. and surface-active agents may be added to the mixture to promote initimate contact of the two liquid phases.

Title: Can filling machine
Inventor: MILLER JACK MEREDITH
IPC: B65B3/12
Filed: 1964-02-12
Abstract: 1,032,558. Can filling machine; delivering measured quantities of pasty material. MARLEN EQUIPMENT CO. Feb. 12, 1964, No. 5925/64. Headings B8C, B8N and B8T. Feeding material.-A machine (Fig. 4) for filling cans with pasty material comprises means for feeding a measured quantity of material F laterally into the nozzle 51 and a reciprocating ram 111 which ejects the material F into the can A. As the material F is pushed into the can A the can slides off the nozzle 51 and at the end of the ejection stroke the end of the ram projects beyond the end of the nozzle so that any material thereon can be wiped into the can. On the configuration described, the retracted ram 111 is stationary whilst the pin 120 moves in the slot 140, during which time the measure of material F is fed into the nozzle 51. Measuring material.-The means for feeding and measuring the material comprises a rotor 57 (also Fig. 9, not shown), which rotates in the housing 26 (Fig. 4) and an adjustable piston 89 in the bore 62 of the rotor 57. The piston 89 consists of two separable halves 90, 91 (Fig. 8, not shown) which are screwed to a rod 96, and the volume of material issued each time from the rotor may be varied by adjusting the length of the piston. The piston 89 is forced along the bore from bottom to top by the pressure of the material in the tube 108, and this forces the quantity F out of the bore and into the nozzle. As the ram ejects the quantity F, the rotor is turned so that the piston is again at the bottom of the bore, and the quantity 9 is ready to be fed into the nozzle. The machine described comprises two halves as above, synchronized so that cans are filled alternately at the two nozzles.

Abstract: 737,460. Electric accelerometers. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 18, 1953 [March 11, 1952], No. 6306/52. Class 40 (1).  A rotational accelerometer comprises a plurality of piezo-electric devices compressed between a base member, adapted to be secured for coaxial rotation with a body whose angular acceleration is to be investigated, and a free mass rotating with the base member, the pressure on the piezo-electric devices varying in dependence on the angular acceleration; the piezo-electric devices are so arranged that the changes in their individual electrical outputs consequent upon angular acceleration are additive, whereas the changes in their individual outputs consequent upon transverse acceleration tend to cancel out in the total combined output. As shown, the base member may comprise a semicircular yoke 2, Fig. 1, fixed to a shaft 1, two piezo-electric devices 3 being disposed on opposite sides of the shaft 1 between the yoke 2 and the free mass 4 which consists of a second yoke pressed towards the first by two flat springs 5 having a stiffness which is small compared with that of the piezo-electric devices 3. In an alternative construction, Fig. 5, the free mass comprises a bar 24 rotatably mounted in a slot in a generally cylindrical base member 22 and engaging piezo-electric devices 23 and resilient blocks 25. The outputs of the piezo-electric devices are picked up by means of a slip-ring assembly, Fig. 3, comprising two steel rings 9 and 10, which rotate with the body under investigation and are connected to the piezo-electric devices, and two rings 15 and 16 separated by an insulating ring 17 which are free to rotate relatively to the rings 9 and 10. Alternatively, a slip-ring assembly of the type described in Specification 737,489, [Group XXXVI], may be used.

Abstract: In the depolymerization of polycaprolactam using orthophosphoric acid, steam and e -caprolactam (see Division C2) a residual product consisting of a complex mixture of high-melting cross-linked polymer and phosphorus-organic compounds is obtained.  This may be converted to flame-proof shaped solid or foamed objects.ALSO:e -Caprolactam is recovered from nylon 6 by continuously feeding the nylon, orthophosphoric acid in an amount of 0.1 to 5% by weight based on the nylon, and steam into a depolymerization zone, at 220 DEG  to 375 DEG C. and 0.5 to 6 atmospheres, and withdrawing a mixture of steam and e -caprolactam, the rate of feed being such that the mixture contains not more than 80% by weight of e -caprolactam and the volume of reactants in the zone remains constant.  The nylon and acid may be added separately but are preferably added together in a solution in water and e -caprolactam. The reactants may contain up to 5% of copper, manganese or tin as corrosion inhibitors.  The polymer may comprise some units derived from monomers other than caprolactam, e.g. other lactams, diamines or diacids.
