IPC: B65G39/16
Filed: 1953-06-19
Abstract: 736,633. Hollow rollers. UNITED STATES STEEL CORPORATION. June 19, 1953 [July 28, 1952], No. 17102/53. Class 34 (1). [Also in Groups VIII and XXIII] An elongated object, such as a metal sheet or an abrasive belt B<SP>1</SP>, Fig. 6, is automatically centred by roll assemblies 63 ... 67, each comprising a pair of rolls 4, Fig. 2, rotated in the same direction and at the same velocity about axes 8, 10 and 10, 12, which intersect at a point between the rolls when under load, each roll having a flange 30 and a surface which increases in diameter towards its inner end, the diameter of the inner end beng greater than that of the flange. The rolls are mounted for rotation on a bent shaft 6 and connected by pins 28. When using a belt, such as leather, having a low modulus, a hollowness amounting to several thousandths of an inch at the line of minimum distance between the flanges 30 is provided to increase the pressure at the belt edges and thus the centring effect while with a belt, such as metal, having a high modulus a raised ring (not shown) is provided on the inner end of each roll to prevent excessive bending of the belt. The flanges 30 oppose movement of the belt due to external forces such as lateral pressure. In Fig. 4, the rolls are provided with a rubber covering 58 having peripheral grooves 60 and are connected by pins 48, collars 46 and locked nuts 52 with a rotating shaft 36 which is of smaller diameter than the inner bearings 54, to permit deflection of the rolls under load. The abrasive belt is pressed against the work by a pivoted former 68 and preferably emerges at a small angle A. Specifications 709,908 and 717,671, [both in Group XVI], and 735,561 are referred to.

Title: Improvements in or relating to period meters for nuclear reactors
Inventor: HARRISON DONALD
IPC: G01T1/30
Filed: 1961-05-12
Abstract: 950,947. Monitoring nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 7 1962 [May 12, 1961], No. 17458/61. Heading G1A. [Also in Divisions G4, G6 and H3] The period of a nuclear reactor is measured by apparatus comprising a logarithmic amplifier feeding a differentiating amplifier, in which a variable time constant circuit includes a component whose impedance is varied in accordance with the output of the logarithmic amplifier. The reactor flux is measured by an ionisation chamber the output of which is fed through the logarithmic amplifier to a differential amplifier comprising a long tailed pair V 1 , V 2 , Fig. 3 and transistors VT1- VT4, which is responsive to the rate of change of its input by virtue of the feedback connection R9, C5, TH2. The time constant of this connection varies with the thermistor TH2 which is controlled by the logarithmic amplifier output through transistors VT5 and VT6. A thermistor TH1 adjusts this control current to compensate for ambient temperature variations. A monitoring 200 mV square wave is applied through condenser C7 and if it fails to pass through the system an alarm is given. In a modification, Fig. 4, thermistor TH2 is replaced by a transistor VT11 which is switched between states in which it constitutes high and low impedence respectively between the point P and ground, by pulses applied to its base. The mark/ space ratio of the pulses is controlled in accordance with the output of the logarithmic amplifier by a blocking oscillator comprising a transistor VT12 so that the mean impedence presented by the transistor VT11 varies with the logarithmic amplifier output. The thermistor TH3 compensates for thermal drift in transistor VT10. Preferably the time constant change ¢ decade for every decade of ionisation chamber current. Specification 950,946 is referred to.

Patent GB-358512-A (GB)
Title: Improved process for the production of fine threads from cellulose compounds
IPC: D01F2/28
Filed: 1930-06-05
Abstract: Artificial threads composed of cellulose derivatives, particularly cellulose acetate silk, are fixed by stretching in the presence of a swelling medium or a mixture of swelling media which have only a slight dissolving capacity for the cellulose derivative, and also of an organic substance which is capable of precipitating the cellulose derivative from its solution in organic solvents and is adapted to repress the slight solvent power of the swelling medium.  Suitable swelling agents are methylene chloride, chloroform, tetrachlorethane, and mixtures thereof; and the following may be used as precipitants,-carbon tetrachloride, trichlorethylene, perchlorethylene, benzene and its homologues, benzine and other hydrocarbons.  The composition of the bath and its temperature depend on the conditions of treatment.  The process may follow on directly from the production of the threads either by dry or wet spinning processes, or it may be applied to the finished products; and stretching may take place either in the treatment bath, or after the threads have left the bath and while still saturated with liquid. Stretching which may be performed in one or a series of stages, may be effected by drawing the threads over guides arranged in zig-zag formation or by the aid of other mechanical arrangements offering frictional resistance to the passage of the threads, or by passing the threads over a series of rollers &c. rotating at increasing peripheral speeds, or by giving the threads an extended air run, or by drawing the threads through the bath at relatively high speeds. The stretching may be from 300-800 per cent or more, normally producing threads with filaments of 2, 1, 0,5 deniers or even finer filaments; and there may be used as starting material threads having filaments of unusually high litre of 10, 20 deniers or even higher. The residue of the treating bath are usually removed by evaporation; and the drying is carried out under conditions such that shrinkage of the threads is prevented. The stretched threads have an increased dry and wet strength, a reduced elongation, and a lustre approaching that of natural silk; and the cross section of the filaments is rounded and more uniform.  For examples, baths consisting of mixtures of methylene chloride and carbon tetrachloride or benzene are used in the fixing of cellulose acetate silk.  Specification 336,217, [Class 2 (ii), Cellulose &c.], and 352,445 are referred to.  Reference has been directed by the Comptroller to Specification 323,790, [Class 2 (ii), Cellulose &c.].
