Title: A storage sytem for fissile bars, etc.
IPC: G21C19/40
Filed: 1965-04-28
Abstract: 1,031,559. Storing radio-active material. REACTOR CENTRUM NEDERLAND. April 28, 1965 [May 1, 1964], No. 17918/65. Heading G6R. A storage rack for fissile material is formed of metal or concrete and provides a series of shelves or trays which carry the material and which are separated by either spaces or plates of a neutron-absorber to prevent the formation of a critical mass of fissile material. To prevent criticality being attained by the accumulation of a liquid moderator, e.g. water, in the trays carrying the fissile material, the latter are inclined to its horizontal to permit free drainage of liquid moderator. The separating spaces are designed to accept liquid moderator from the shelves, so as to decouple the separate fissile masses, in the event of immersion of the rack. Each separating space has a transparent front wall to enable the interior to be clearly viewed. A reduction in the size of the arrangement is effected if the separating spaces are replaced by absorbing slabs. The arrangement is intended for nuclear fuel U-235 of not more than 3% enrichment.

Title: A process for preventing the bleeding of dyed textiles on wool
IPC: D06P3/16
Filed: 1931-06-22
Abstract: In processes in which dyed wool and undyed wool are treated simultaneously in a bath having a pH value not greater than 7, particularly in acid fulling, water fulling or acid boiling processes, bleeding of the dyed wool on to the undyed wool is prevented by the addition to the bath of a textile auxiliary which has the property of retarding the absorption of acid dyestuffs on wool.  Phenol-sulphur condensation products, condensation products of aromatic sulphonic acids, e.g. naphthalene-sulphonic acids, with aliphatic, cyclic and aromaticaliphatic alcohols, or with benzoin, sulphoricinoleates and natural or artificial tanning materials, e.g. condensation products of formaldehyde with naphthalene sulphonic acids, are specified as suitable auxiliaries.  Examples are given of the treatment in various acid and neutral baths of undyed wool and wool dyed with the following dyestuffs: Acid blue RBF, Kiton fast orange G, Kiton red G,6B, or S, Neolan orange GRE, Neolan green B, Kiton blue A, Orange II, Fullacine red G, Acid Rhodamine 3R, Acid violet 6BN, Kiton pure blue FF, V, Benzyl green B, Brilliant Kiton red B, and Benzyl violet 5BN.  The substances added to the baths to prevent the bleeding of the dyed wool include the product described in example 1 of Specification 319,249, tannin and other tanning materials, elg. sumach or catechu extract, Katanol W and WL, Albatex WS, Nekal BX, Leonil S, Prästabite oil V, and condensation products of naphthalenesulphonic acids and formaldehyde.  Specifications 15456/15, 248,007, 269,970, 304,742, and 305,269, [all in Class 15 (ii), Dyeing, Processes &c. for], also are referred to.

Patent GB-640021-A (GB)
Title: Improvements in transmitting and receiving equipment
IPC: G01S7/03
Filed: 1947-07-08
Abstract: 640,021. Radio ,receiving systems. BRITISH THOMSON-HOUSTON CO., Ltd. July 8, 1947, No. 18055. Convention date, Aug. 17, 1942. [Class 40 (viii)] [Also in Groups XL (a) and XL (c)] In a radar system wherein the transmitter 1 and the receiver 2 are connected to a line 5 leading to a common antenna, the receiver is protected from transmitted pulses by a stub line 8 which is short-circuited at 12 and provided with a spark-gap or other non-linear impedance at 13. The point of connection of the receiver to line 5 is connected to a point in line 8 a short distance away from 12, via a condenser 14 which is resonant at the operating frequency with the inductance presented by line 8 when 13 is short-circuited. The line 8 is also arranged by the provision of condensers 15, 16 to compensate for the effect of reflections from the transmitter 1 on the incoming signals received from the antenna. The junctions of the transmitter and receiver with the line 5 are spaced apart by an odd multiple of a quarter of a wave-length of the transmitter and the stub line 8 is also one quarter of a wave-length between the shortcircuit point 12 and the impedance 13. During reception, the tuned line 8 presents relatively high impedance to the line 5 and therefore has little effect on received signals. During transmission, however, the impedance 13 breaks down and the line 8 presents low impedance across the line 5 so as to protect the receiver 2. The stub circuit has little effect on the transmitter in view of the high impedance produced at the junction 6 due to the short-circuit at 7. During reception when the impedance 13 has a high value, reflection at the junction 6 may be compensated by variable condensers 15, 16 which respectively produce inductive and capacity effects at the junction 6, so as to match the conductance of the receiver with that of the line 5. A constructional arrangement of the junctions 6. 7, lines 5, 8, condensers 14, 15, 16 and spark-gap 13 is described with reference to Fig. 2 (not shown). In this arrangement the spark-gap 13 is placed in an enclosure containing for example, hydrogen or helium, and is provided with spring contacts which engage the line 11 so as to allow for expansion and contraction of the line. The condenser 16 is of the cylindrical type having an inner plug electrode manually adjustable through a rack-and-pinion mechanism. The condenser 15 comprises two plates, one of which is adjustable towards and away from the other longitudinally of a channel 4 by a screw-threaded spindle.

Title: Improvements in electrical systems for controlling a physical quantity
IPC: H01H47/04
Filed: 1960-05-24
Abstract: 929,292. Automatic control systems. A. SILIANI, [trading as COSTRUZIONI ELETTRO-MECCANICHE]. May 24, 1960 [May 26, 1959], No. 18209/60. Class 38 (4). An electrical system for controlling a physical quantity, e.g. temperature, comprises a bridge circuit RV, R2, R3, R4 in which RV is variable with the quantity to be controlled and an amplifier, e.g. a transistor T, connected in a diagonal AB of the bridge to allow a control current to be supplied to a relay Re when the bridge is unbalanced, the characteristics of the bridge being modified upon pick-up of the relay in such a manner as to reduce the control current to a value close to the value at which the relay drops off. As shown, this modification is effected by arranging two resistances R5, R6 in such a manner that they may be inserted in parallel with the resistances RV and R2 respectively through a change-over switch X controlled by the relay Re, the values of R5 and/or R6 being such as to vary the biasing of transistor T so as to bring the collector current back to a value close to that at which the relay drops off. A minimum variation of RV is then sufficient to cause operation of the relay. A resistance-capacitance coupling may be connected to the resistances R5, R6 (Fig. 5, not shown) to influence the control current under unstable equilibrium conditions. Zener diodes (Figs. 7 and 8, not shown) may be provided to stabilize the bridge.

Abstract: 646,794. Earth inductor compasses. SPERRY GYROSCOPE CO., Inc. July 15, 1947, No. 18830. Convention date, Aug. 2, 1946. Addition to 600,051, [Group XXXVIII]. [Clase 37] [Also in Groups XX and XXXVIII] In stable reference apparatus of the type in which a stretched wire 13 is maintained in vibration at right angles to the direction of a magnetic field, e.g. the horizontal component of the earth's field, the drive provided by the reaction of the steady field and that due to an alternating current flowing in the wire is supplemented by using a wire of magnetic material and varying the tension of the wire magnetostrictively at a suitable frequency. As shown, the directional drive is given by supplying the wire from the output of an amplifier 27 whose input is supplied from a capacitive pick-up 19 co-operating with the wire, and whose output may be limited by an automatic gain control. The amplifier also supplies coils 31, 33 surrounding the wire through a phase adjuster 45 to provide the magnetostrictive drive. The proportion of the two drives is set by potentiometers 37, 47, and preferably the bulk of the energy is supplied by the magnetostrictive drive. The apparatus is initially set up with the casing in such a position that the wire vibrates parallel to the plane of a second capacity pick-up 51. When the casing is moved, however, the wire continues to vibrate in the E-W plane and the output from 51 controls a servomotor 67 to restore the casing to its original orientation in space, at the same time driving an indicator disc 75. Specification 600,165 is referred to.
