IPC: F16T1/08
Abstract: 1,050,395. Steam traps. H. R. GERDTS, and W. F. GERDTS, [trading as GUSTAV F. GERDTS K.G.]. Feb. 9, 1965 [Feb. 12, 1964], No. 5499/65. Heading F4U. In steam traps of the kind having a thermostatically operated main valve 9 and an auxiliary valve 14 opened by abnormally large quantities of condensate passing the valve 9 and acting on a baffle member 17, the baffle member and auxiliary valve are disposed coaxially. Normal quantities of cool condensate entering the trap at 4 pass through channel 19 over the thermostatic elements 10 and past valve 9 to the outlet 5. Rise of temperature closes the valve 9 to prevent loss of steam. Abnormally large flow of condensate past the valve 9 impinges on the baffle member 17 and opens valve 14 against spring 15. Condensate then passes through channel 22 and bore 13 direct to the outlet 5, as well as through the valve 9.

Abstract: 1,228,866. Electric motors; inverting. TOKYO SHIBAURA ELECTRIC CO. Ltd. 9 May, 1968 [15 May, 1967], No. 22060/68. Headings H2A and H2F. A brushless D.C. motor has bridge-connected main thyristors 11-16 connected in pairs to motor windings U, V, W so that thyristors 11- 13 control the supply to the winding from the positive supply 41 and thyristors 14-16 the supply from negative supply 42. Main thyristors 11-16 are made to conduct in accordance with rotor position, sensed by sensor 33, under the control of gate control 34 to provide a synchronous torque on rotor 32. Each main thyristor conducts for 120 degrees and is switched off by providing an opposite polarity voltage pulse by connecting voltage source 36 into the circuit and short-circuiting the commutated winding through diode bridge 21-26. In operation, to forcibly quench positive side main thyristors 11-13, switching circuit 37, which includes a transistor or thyristor, is switched on to apply voltage V A  to point 43 to turn off the respective main thyristor and thyristor 18 is made conductive to allow the stored energy in the windings to be dissipated through diodes 24-26 and help to turn the thyristor off. In the case of a negative side main thyristor, the thyristor 17 is made to conduct at the same time as circuit 37 by means of pulses from gate control 34. Reactor 35 is included in the supply circuit so that an effective constant current source is obtained.

Abstract: 1,229,215. Thermographic material. GEVAERT-AGFA N.V. May 14, 1968 [May 23, 1967], No. 23983/67. Addition to 1, 184, 054. Heading G2C. A thermographic process according to claim 2 of Specification 1,184,054 wherein either the aqueous developer or the water permeable, hydrophilic interlayer contains a ferricyanide of Zn, Cd, Hg, Cu, Ag, Au or Pb and the other one (i.e. developer or layer) contains a dye, the dye and ferricyanide being brought together in the water permeable areas of the thermographic material to produce mordanted dye image. Alternative combinations of reactants in the interlayer and developer to produce a mordanted dye image, are: (i) either a compound of one of the specified metals or a water-soluble ferricyanide in the interlayer and the other component in the developer with either a leuco dye base or an aromatic primary or secondary amine in either developer or interlayer, (ii) both the water-soluble ferricyanide and the specified metal compound in the interlayer and the leuco dye base in the developer (iii) a ferrocyanide of a specified metal or a specified metal compound and a ferrocyanide in the interlayer and a cationic dye in the developer and (iv) a specified metal compound in the interlayer and a compound capable of chelating with the specified metal (e.g. an o-hydroxy azo compound, an o, o<SP>1</SP>-dihydroxy azo compound or a compound of formula: - where R is hydrogen, alkyl or aralkyl and 2 and 2<SP>1</SP> complete 5- or 6- membered heterocyclic rings) in the developer. The heat-sensitive material is imagewise exposed so that the hydrophobic layer melts into the hydrophilic layer at the exposed areas and is then developed in these areas to produce a fixed mordanted or chelated coloured image. In the examples, the heat sensitive material contains zinc oxide and optionally potassium ferricyanide in the interlayer and after imagewise exposure is developed with an acidic solution of a leuco dye base or phenetidine and potassium ferricyanide (if not in interlayer) to produce a colour-part dye image. Alternatively the ferricyanide may be replaced by potassium ferrocyanide in the interlayer and a dye used as developer. A further alternative is to replace zinc oxide with mercuric stearate. The top layer in all examples is petroleum wax.

[Also in Division C1] The suitability of polymeric synthetic filaments of non-cellulosic origin which are capable of undergoing cross-linking when heating in the presence of a dehydrogenating agent, for carbonization is improved by thus heating the filaments within a temperature range of 175- 300‹ C., while tensioning the filaments; the temperature of the filaments being increased within the said range at a rate of 3-35‹ C. per hour. The filaments may be heated in a stream of air, or of modified air, which contains either up to 40% or up to 10% of oxygen by volume; chlorine or liquid sulphur may also be used as dehydrogenating agents. The dehydrogenating agent used may be supplemented with other dehydrogenating agents, for example boric acid, ammonium sulphate, and ammonium phosphate; and a radical producer for example α- nitrophenol or parathiocresol or a radical attracter e.g. hydroxylamine or urea. In a preferred embodiment, polyacrylonitrile filaments were pulled through a furnace with a temperature profile such that a rate of increase of 35‹ C. per hour was obtained within the range 175-300‹ C. The filament obtained was black and flexible, having an elasticity modulus of 7À9 x 10<SP>4</SP> Kp/cm.<SP>2</SP> and a tear resistance of 0À9 x 10<SP>3</SP> Kp/cm.<SP>2</SP>.

Abstract: 1,265,964. Fuel elements. BRITISH NUCLEAR DESIGN & CONSTRUCTION Ltd. 9 April, 1969 [9 April, 1968], No. 17062/68. Heading G6C. A sleeved fuel element assembly support arrangement comprises a triple armed support member 21 which carries the fuel assembly 10, and three Zr-alloy wires 22 extending vertically outside the assembly, being attached at their lower ends to the arms of the support member 21 and at their upper ends to lifting means such that the assembly may be lifted out of a fuel channel 11 extending through a reactor core 12. The lifting means comprises a steel carrier tube 13 which is carried by a plug 14 within a standpipe 15 passing through the top cap 16 of the concrete pressure vessel housing the reactor. The fuel assembly 10 includes a graphite sleeve 17 which contains for example, a stack of sleeved layers of fuel pins (generally referenced 18), a reflector 19 and a spiral neutron plug 20. The wires 22 extend through grooves formed in the outer wall of the sleeve 17 to an anchorage point in the carrier tube 13. The grooves are shaped so that their radially outermost width is less than the diameter of the wires 22, which are thus trapped in position within the grooves. The length of the wires 22 is such that they are slack when the fuel assembly 10 is in position within the fuel channel 11. Coolant gas is fed to the underside of the core 12 and some of this passes around the core 12 and into the fuel channel 11 through an opening 25. This gas passes down the outside of the sleeve 17, thereby cooling the moderator of the core 12, to rejoin the remainder of the coolant gas flow and pass up the fuel assembly 10 within the sleeve 17. In order to refuel the reactor, the plug 14 is withdrawn through the standpipe 15 and once the slack in the wires 22 has been taken up, the fuel assembly 10 is lifted out of the channel 11. The provision of a spherical rocker on the support member 21 allows the fuel assembly 10 to take up the position in which the three wires 22 are equally loaded.
