Title: Electrical thermometers
Inventor: THOMAS DENNIS MAURICE
IPC: G01K7/02
Filed: 1959-02-13
Abstract: 934,669. Temperature measurement. SPERRY GYROSCOPE CO. Ltd. April 8, 1960 [Feb. 13, 1959], No. 5187/59. Class 40 (1). An electrical thermometer comprises an amplifier to whose input terminal are applied three currents: (1) representing the output of a thermocouple or thermopile applied through a resistor; (2) representing the temperature of one junction or group of junctions so that the algebraic sum of (1) and (2) represents the temperature of the other junction or group of junctions; and (3) constant but adjustable. In the Figure one set of junctions 1 is at the temperature it is desired to measure and the difference in temperature compared with junctions 2 generates an e.m.f. which causes current to flow through resistor 3 to provide input (1) to amplifier 5. Feedback through resistor 7 ensures that the amplifier input impedance is low. A temperature-variable resistor 9 in thermal contact with the junctions 2 is fed with D.C. via an adjustable temperature-stable resistor 10, and the voltage across resistor 9 drives current through a further adjustable resistor 12 as input (2) to the amplifier. Re sistors 10 and 12 are set so that the rate of change of input (2) with temperature is the same as that of input (1), and thus the algebraic sum of these inputs always represents the temperature of junctions 1 referred to an arbitrary zero point determined by the settings of resistors 10 and 12. To enable this zero point to be shifted without upsetting the equality of rates of change mentioned above, the amplifier has a third current input from a D.C. source via a potentiometer 14 and resistor 17. The amplifier can include a modulator to convert the D.C. input into A.C., and a rectifying and smoothing circuit to give a D.C. output to an indicator, recorder or controller 6. According to the Provisional Specification, when the amplifier output is applied to a plurality of receiving instruments, each of these can have an individual setting means (e.g. shunt diode resistance network) to provide different values of reference zero. If the temperature-sensing unit is a thermopile with both groups of junctions mounted in a measuring head, the compensating resistor 9 can be replaced by a thermocouple having one junction in heat-exchange relation with one set of the thermopile junctions and the other junction at a standard temperature. Equality of rate of change of the signals could then be achieved by arranging for the compensating signal to move the reference index of an indicating instrument while the thermopile signal moves a scale against which the index is read.

Title: Improvements in and relating to systems for magnetic field investigation
IPC: G01R33/02
Filed: 1944-03-20
Abstract: 580,445. Gyroscopic apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. March 20, 1944, No. 5199. Convention date, March 19, 1943. [Class 97 (iii)] [Also in Groups XXXV and XXXVI] A magnetometer for detecting anomalies in the earth's magnetic field such as those produced by mineral deposits comprises a detecting coil, the position of which relatively to the field is controlled by a pair of coils perpendicular to each other and perpendicular to the field. The axis of the coil is maintained parallel to the field by controlling its position in accordance with variations in the components of the field in a plane perpendicular to the coil axis and the magnetic flux cutting the coil is measured to ascertain the magnitude of the field anomaly. The detecting coil 1 of the magnetometer is maintained in predetermined position relative to the earth's field by a gyroscope. A gimbal ring 7 is rotatable about pivot pins 8 carried by brackets 4, 3 and carries pins 10 defining the perpendicular axis about which the housing 14 containing the rotor is rotatable. A magnetic core 24 is supported'by the housing 14 in fixed relation to the coil 1. On this core are wound mutually perpendicular positioning magnetometer coils 25, 26, 27, 28 which measure the components of the magnetic field parallel to their axes and hence perpendicular to the gyroscope spin axis. These components will be zero when the axis of the coil 1 is in the desired direction of the total field. The detecting element comprises a pair of parallel coils 1, 30 supported by a frame 29 which is carried by the gyroscope housing 14. These coils comprise high permeability cores or strips 31, 32 upon which the coils are wound. The rotor housing 14 is provided with a manifold through which the impelling fluid flows after driving the rotor and escapes through two pairs of diametrically opposite valves 34, 37, the pairs being at right angles to one another. These pairs of valves are controlled by the expansion of wires carrying heating currents derived from the positioning magnetometer coils 25 ... 28. The reactions of the fluid escaping through the valves apply torques which control the precession of the spin axis until this is perpendicular to the magnetic field. The coils 1, 30 then measure or detect abnormal flux distributions due to the presence of mineral or oil deposits, obstacles or metal objects.

Abstract: 657,236. Endless-belt conveyers. HUWOOD MINING MACHINERY, Ltd., and BAINBRIDGE, F. Feb. 25, 1949, No. 5256. [Class 78 (i)] In a belt conveyer of the kind having a framework built-up of sections of sheet-like form which cover the lower run of the belt and carry rollers for supporting the upper run and which at their ends are associated with supports which bear rollers for supporting the lower run, the framework is built-up of a plurality of substantially rectangular sheets of less width than the conveyer and of cradle devices disposed transversely of the belt, the sheets being mounted side-byside on the cradles to cover the width of the lower belt rim and being fitted with stiffening means along each longitudinal edge, the cradle devices being provided with removable cross-members to support the sheets at the ends, and the sheets and cradles being adapted for the mounting fixedly in position thereon respectively of idler rollers for supporting the upper run of the conveyer and of idler rollers for supporting the lower run. As shown, the return run of the belt is covered by pairs of sheets 1, 2 stiffened at their sides by lengths of tubing 4, 5 and welded at their ends to bars 7 projecting at each side at 8, 9. Intermediate the ends of the sheets 1, 2 are bars 22 welded in recesses in the tubing and having portions 23 projecting beyond the sides of the sheets. The cradles 13 are connected in pairs by tubes 14 and are each slotted at 15 to receive the ends of a cross-bar 16 stiffened by a piece of tubing 17. The depth of the slots 15 is such that a bar 16 may be applied to a pair of cradles by inserting it at one end through the slot 15 of one cradle, moving it back a little to enter its other end into the slot 15 of the other cradle and then lowering the bar in the slots 15 to allow projections 18 on its underside to enter sockets 19 welded to the inner side of the cradles. Rollers 21 for supporting the lower belt run are supported by cross-members 20 which span the tubes 14. To assemble the structure, the cradles are laid along the conveyer site and the lower run of the belt laid on the rollers 21. The cross-bars 16 are now mounted on the cradles and these latter then adjusted so as to be at slightly less distance apart than the length of the sheets 1, 2 so that the latter may be rested on their ends on the cross-bars. A sheet 2 on the far side of the conveyer is first laid on the cross-bars of two adjacent cradles and back a little from the far end thereof and then slid along until the projections 8 on the sheet slip into the upper part of the slot 15 of adjacent cradles. The near side of the sheet is then laid on the bars 16 a little way back from the near ends of the cradles and then slid towards those ends to bring the projections 8 into the adjacent slots 15. After the pairs of sheets have been assembled, frames 25 carrying idlers 26 are secured by bolts 24 to the projections 23 on the bars 22.

Patent GB-385783-A (GB)
Title: An improved apparatus for making artificial films or skins of cellulose and cellulose derivatives
IPC: D06F47/00
Filed: 1932-02-22
Abstract: In the manufacture and treatment of artificial bands, skins, or films of cellulose or cellulose derivatives the speed of the film through the apparatus is automatically adjusted to the changing shrinkage which arises, by automatic control of the rotational velocity of one or more of the forwarding rollers.  The film passes between at least two positively driven rollers, <PICT:0385783/IV/1> and round a guiding member arranged between the two rollers.  The guiding member can be displaced in a vertical direction by means of the film to operate a control member which acts positively on the drive of one of the pair of forwarding rollers.  The shortening or lengthening of the film between the pair of forwarding rollers leads to a raising or lowering of the guiding member which operates the control member and results in a lowering or raising of the rotational speed of one of the forwarding rollers corresponding to the changes in shrinkage of the film. The device results in films of uniform mechanical properties and good results are obtained even when nonhomogeneous solutions containing cellulose of varying states of degradation are used. As shown, a film 1 obtained by extrusion of viscose, or a solution of cellulose in cuprammonium, or a solution of nitrocellulose, or other cellulosic solution, is led over a system of rollers 3, 7, 8 through the tank 4 containing precipitating or other liquid 2.  It passes over a roller 9 suspended on endless chains 11 provided with counterweights 14.  It then passes over roller 12 to a withdrawal roller 15.  The varying shrinkage of the film is shown by a shortening of the loop between rollers 7, 12, and consequent rise of roller 9, and movement of the chains 11.  This movement is transmitted to a switch wheel 16 of a resistance 17 controlling the speed of a motor 18 which drives the roller 15.  An increase in shrinkage of the film is compensated by a reduction in the speed of rotation of roller 15 and a slackening is compensated by an increase in speed.  The film then passes into a further bath 6 where a similar compensating device may be used.  Such a device may also be used in the drying operation.  Instead of controlling the speed of the driving motor, the automatic regulation of the speed of the forwarding roller may be effected by providing a conoidal drive or other transmission drive under the control of the film guiding member.
