Title: Improvements in or relating to nuclear reactors
Inventor: R PHILIP CLOUDSLEY WARNE
IPC: G21C19/04
Filed: 1959-07-31
Abstract: 931,552. Nuclear reactors. ATOMIC POWER CONSTRUCTIONS L t d. July 11, 1960 [July 31, 1959], No. 26444/59. Class 39 (4). A restrictor for a coolant channel 1 of a gas-cooled nuclear reactor comprises aremovable gag 11 which is forced against a fixed location member 5 by the combination of resultant forces acting downwards on the gag, viz. those due to the static pressure round the gag, the static pressure resulting from the downward component of the momentum force of the gas stream, and the weight of the gag. The gag is provided with a lower seat 12 which engages the main seat 8 of the member 5 and an annular seat 13 which engages the ledge seat 9 of said member with a small clearance. Cylindrical surfaces 10, 14 on gag 11 and member 5, respectively, engage each other. A cavity 15 is thereby formed between the gag 11 and member 5 and is connected with the upper surface 17 of the former by a passage 16. The gag 11 restricts the opening 18 at the end of the channel 7, the deflecting surface 19 turning the coolant flow through this channel back into an axial flow along channel 1. There is thus a pressure drop between channel 7 and upper surface 17 and because of the passage 16, the pressure in cavity 15 equals that in channel 1 adjacent surface 17, thus producing a . resultant force acting downwards on the gag.

Title: Improvements in or relating to electrical signalling systems
IPC: H04Q1/453
Filed: 1931-09-28
Abstract: 390,161. Electric signalling systems. FLOWERS, T. H., 60, Windsor Road, Palmers Green, London. Sept. 28, 1931, Nos. 27007/31 and 8109/32. [Class 40 (i).] Signalling is effected by trains of damped oscillations which are produced by shunting a charged condenser across an inductance. The condenser may be charged over the signalling circuit and the oscillations may be fed to the line via a thermionic valve. To produce oscillations of considerably greater voltage than the charging voltage, a subsidiary condenser may be provided for storing the energy, the condenser being discharged into an oscillatory circuit comprising a condenser of smaller capacity to produce the signalling oscillations. Frequencies of 500, 600, 750, and 900 cycles per second are suggested as suitable. As shown in Fig. 1, the signalling line L1, L2 is connected to four parallel tuned circuits separated by resistances R1 .. R4. The condensers C1 .. C4 are normally charged and when one of the keys, such as K1, is closed the relative condenser, C1, discharges by way of the oscillatory circuit and produces a train of damped oscillations which is transmitted to the line by way of the relative transformer T1. The resistance R5 improves the operation. In an alternative arrangement a single transformer is provided common to the four tuned circuits. In the arrangement shown in Fig. 3, a thermionic valve is used. The resistances R1 .. R4 and condensers C1 .. C4 are provided as in Fig. 1 and inductances I1 .. I4, which are of the metal dust core type, are fitted as shown. When a key K1 .. K4 is depressed the relative normally charged condenser, which is charged from the high tension supply, discharges through its associated inductance and a train of damped oscillations of the appropriate frequency are fed through the valve V and transformer T to the line L3, L4.

Title: Improvements in or relating to sequential switching apparatus
Inventor: CARROLL JOHN LOUIS
IPC: H03K17/62
Filed: 1958-08-26
Abstract: 861,727. Transistor switching circuits. MICROCELL Ltd. Aug. 26, 1959 [Aug. 26, 1958], No. 27371/58. Class 40(6) Apparatus for rendering a number of circuits conducting for a short time interval in succession comprises a number of transistors to which a sloping waveform is applied so as to render the transistors conducting successively, means being provided in the emitter collector path of each transistor which interrupts the path when the transistors conduct. In the figure transistors 10, 11, 12 are biased by resistors 20 to 24 in increasing amounts so that a sawtooth wave applied from a circuit (such as a "boot strap" circuit 26) renders the transistors conducting in succession. The conduction of each transistor operates one of relays 13, 14 and 15, the corresponding contacts of which 17, 18 and 19 open circuit the emitter circuit so that the relays are de-energized after a short time interval. The relays however may be maintained operated by a holding circuit or latching arrangement. The relays may be replaced by fuses which blow when the circuits conduct. In addition, the biasing circuits may be omitted and the sawtooth wave applied to successive transistors through an increasing number of diodes so that due to the forward contact potential of the diodes or their reverse zener potential the transistors conduct in succession (Fig. 2, not shown).

Title: Mixed polyesters
Inventor: AITKEN ROXBURGH RICHMOND
IPC: C08L67/02
Filed: 1956-09-07
Abstract: A liquid polyester plasticizer is the polycondensation product of glutaric acid and a mixture of 20-65 molecular proportions of 1 : 6-hexanediol and 80-35 molecular proportions of 1 : 5-pentanediol.  A minor proportion of the glutaric acid may be replaced by another dicarboxylic acid and a minor proportion of the diols may be replaced by another glycol.  Polycondensation may be effected by heating together the glycols with the free acids (e.g. in presence of zinc chloride), the alkyl esters of the acids (e.g. in presence of stannous chloride, litharge, zinc acetate, calcium acetate, tetrabutyl titanate or antimony trioxide), the acid anhydrides or the acid chlorides.  The polyesters are particularly useful for plasticizing polyvinyl chloride or copolymers of vinyl chloride and vinyl acetate, unsymmetrical dichloroethylene, styrene or the esters, nitriles and amides of acrylic, methacrylic, fumaric or maleic acids. They may also be used to plasticize chlorinated vinyl chloride polymers, chlorobutadiene-acrylonitrile polymers, chlorinated rubber, nitrocellulose, ethyl cellulose and cellulose acetate. When mixing the polyester with the vinyl chloride resins, the components may be mixed or milled together at a moderately elevated temperature, if desired in presence of an organic solvent or swelling agent for one or both components. Alternatively solutions of the components may be mixed.  Fillers, pigments, other plasticizers, stabilizers and antioxidants may be added.  In examples polyesters are made from (1), (2) and (3) glutaric acid or dimethyl glutarate, 1 : 6-hexanediol and 1 : 5-pentanediol with the addition of (4) succinic acid, (5) 1 : 4 butanediol, (6) diethylene glycol and 2 : 2-dimethyl-1 : 3-propane diol, and (7) phthalic anhydride and diethylene glycol. In Example (8), 50 parts of each of the above polyesters are mixed with 100 parts of polyvinyl chloride and 4 parts of calcium stearate and then bonded on an open mill to effect gelation, and a sheet obtained from the gel by pressing followed by cooling under pressure.
