Patent GB-676126-A (GB)
Title: Improvements relating to the measurement and control of the moisture content of textile and other fibrous materials
Inventor: MILNE JOHN CHARLES
IPC: G01N27/04
Filed: 1950-01-30
Abstract: 676,126. Moisture meters ; resistance measurements. ELECTRIC CONSTRUCTION CO., Ltd. Feb. 16, 1951 [Jan. 30, 1950], No. 2396/50. Class 37. [Also in Group XXXV] The amount of moisture in a length of textile or other fibrous material is measured by connecting it in the input circuit of a magnetic amplifier, the output current of which operates a measuring instrument. Textile material 1 is drawn from a storage beam 2 and passed through a sizing chamber 3 and a drying chamber 4 and thence over conducting rollers 6, 7 and through a pair of feed rollers 8, 9. The feed roller 8 is driven from a motor 10 by a belt 11, the speed of the motor being regulated by a controller 12 operated in accordance with the moisture content of the length of material between the rollers 6, 7. These rollers are connected in the control circuit of a magnetic amplifier 15 comprising a pair of choke coils, the A.C. windings 16, 17 of which are oppositely wound and connected in series with the primary winding 18 of a transformer 19 across an A.C. source 20. The magnetisation of the cores 21, 22 is pre-set by means of a pair of windings 23, 24 supplied through a rectifier 28 and adjustable resistance 29 from a secondary winding 25 of a transformer 26. The magnetisation of the cores is pre-set to a value such that when the A.C. in the windings 16, 17 assists the D.C. in the windings 23, 24 the cores become saturated and the impedance of the windings 16, 17 is decreased. The input circuit is supplied from a secondary winding 33 through a rectifier 34 and high resistance 37. The cores 21, 22 are also provided with short-circuited windings 39, 40 to eliminate harmonics in the A.C. windings. Increase of moisture content causes increase of current in the control windings 35, 36. Resulting increase of saturation of the cores 21, 22 reduces the impedance of the windings 16, 17 and increases the current in these windings and in the primary winding 18. The voltage across the secondary winding 42 correspondingly increases and is applied through a rectifier 43 to the coil 44 of a moving coil voltmeter 45. The pointer 46 rotates clockwise and closes a pair of contacts 47, thereby causing the controller 12 to reduce the speed of the motor 10. The rate of feed of the material through the drying chamber 4 is thereby decreased, so that the material emerging is dryer. Similarly if the material becomes too dry, contacts 50 are closed and the speed of the motor is increased. The voltmeter 45 is provided with a scale calibrated in terms of moisture. The voltmeter may be a recording instrument or may be replaced by a polarised relay for operating the controller 12. Specification 664,435 is referred to.

Patent GB-451033-A (GB)
Title: Improvements in or relating to hydraulically operated machines for surface broaching
IPC: B23Q5/06
Filed: 1935-01-28
Abstract: 451,033. Broaching-machines. KING, T. ST. P. C., c/o Lapointe Machine Tool Co., Ltd., Edgware, Middlesex. Jan. 28, 1935, No. 2811. [Class 83 (iii)] In a hydraulic surface-broaching machine, the tool slide moves in a plane at one side of the ram cylinder 1 and the ram is operated under valve control by means of a variable-delivery reversing- flow pump. The ram cylinder has its piston rod connected to a bracket 4 from which depends the surface broaching slide 5. The cylinder is supplied from a variable delivery reversing flow pump 6 under the control of a valve 7 having a central sliding portion with piston elements 9, 10, 11. The broaching slide carries a projection 32 coacting with collars 35 on a rod connected through linkage as shown with the pump control rod 37 and a pedal 39. The valve is connected through back pressure valve 27 line 26, and filter 28 to the pump casing and thence through line 14 to the reservoir, this low pressure fluid serving for cooling and lubricating the pump. Another connection 30 from the valve to the reservoir includes a check valve 31. In operation the ram is brought to the top of its cylinder by setting the pump to deliver through pipe 16 with the valve in the Fig. 1 position. Both ends of the cylinder are exposed to pressure oil and a quick return stroke of the ram is thus obtained. For the working stroke the pump is reversed and the flow of pressure fluid in the line 15 automatically changes over the valve by lowering the piston portion thereof so that pressure fluid flows to the upper part of the cylinder 1. During the working stroke the excess of exhaust fluid builds up pressure in the line 26 by valve 27 thus minimizing vibrations of the working position. This back pressure may also serve to hold up the ram at any part of the stroke. At the lower end of the stroke the tappet gear 32, 35 acts to reverse the pump and return the ram. The cycle may be repeated continuously or the operator may at any time reverse or stop the machine by the handle 38. In a machine embodiment Fig. 3, the control gear includes bell - crank levers 40, 42, 43, the latter operating a rack 44 to reverse the pump delivery.
Patent GB-558145-A (GB)
Title: Means for the fine regulation of an alternating current voltage
IPC: H01F29/04
Filed: 1942-03-04
Abstract: 558,145. Regulating transformer and other A.C. voltages. ALLMANNA SVENSKA ELEKTRISKA AKTTEBOLAGET. March 4, 1942. No. 2834. Convention date, March 17, 1941. [Classes 38 (ii) and 38 (iv)] An A.C. voltage is progressively regulated between two values by simultaneous regulation in dependence on each other of two saturable inductances connected in series, and at the same time the load current taken from their interconnection is determined. Fig. 2 shows a motor circuit supplied at variable voltage from a tap regulated transformer between the tap bus bars 14, 15, of which are connected the inductances 18, 19. The voltage drop in these inductances is maintained at a fixed phase difference, such as 90 degrees with a view to obtaining minimum dimensions for the inductances, by e.g. a quadrature relationship between the rectified currents in the paralleled saturating windings obtained by inductance 21 and resistance 20. The requisite progressive change may be obtained by means of a winding or windings saturating the inductance 21. The load current is determined by the total current supplied to the saturating windings of inductances 18, 19 which, as shown, is determined by a current transformer 17 in the load circuit. Fig. 3 shows an arrangement in which an automatic progressive change of voltage follows a tap change. Windings 29, 30 acting respectively in aid of and in opposition to a self saturating winding 28 are supplied respectively from half the tap bus bar voltage and by the difference between this voltage and that across one inductance. A modification using the full tap voltage on winding 29 is also referred to. The load current is determined by the saturating current applied to an inductance 25. The invention is not restricted to the quadrature relation referred to but by suitable selection of the impedances in the saturating circuits the phase relation of the inductance voltages may lie anywhere between 60 degrees and 135 degrees the appropriate phase relation between their saturating currents before rectification being respectively 120 degrees and 45 degrees. Resistances adiusted indirectly may be used instead of impedance elements to regulate the saturating currents of the inductances 18, 19 and their phase relation may be controlled by a phase angle meter responsive to the phase relation of the currents in the inductances. Specification 434,456 is referred to.

Abstract: 554,704. Transfers. BURGESS, F. W., and TRAPINEX, Ltd. March 4,1942, No. 2849. Addition to 547,312. [Class 100 (ii)] A transfer comprises a sheet of gummed paper, a reversed design applied thereto, an opaque paint layer covering the reversed design, and a non-reversed design on the paint layer. If the transfer is applied to a transparent surface, one design is visible from one side and the other from the opposite side, but if the transfer is applied to an opaque surface one design only is visible and the paint layer conceals any other matter which the opaque surface may already bear. The transfer may be applied in the ordinary way or as a slip-off transfer. The non- reversed design on the transfer may be covered with a second sheet of gummed paper which may be the backing sheet of a transfer by which the non-reversed design is applied to the paint layer.
