Abstract: 1,153,762. Measuring temperature. C.A. PARSONS & CO. Ltd. April 26, 1968 [May 4, 1967], No.20800/67. Heading G1D. A device for measuring the temperature of insulated electrical conductors e.g. transformer windings 1, comprises a fluid circuit including a tube 2 in contact with the windings 1 and forming a restriction in the fluid circuit, a pump 5 for circulating fluid through the circuit, changes in the viscosity of the fluid in the tube being measured to determine its temperature and thus that of the windings 1. The pump is connected to the two ends of the tube 2 by connections 3, 4 between which a pressure transducer 6 is interposed. The pump maintains a constant flow-rate through the restriction formed by the tube 2 so that the pressure difference detected by the transducer 6 is a direct function of the temperature of the tube 2 and may be indicated on a meter 7. In an alternative embodiment detected changes in pressure across the tube 2 are used to alter the speed of the pump to provide a constant pressure difference, the flow-rate in this case being measured to indicate temperature as a function of the speed of the pump. In a further alternative a piston and cylinder are included to oscillate the fluid in the tube, the frequency of oscillation being controlled to maintain constant amplitude pressure changes across the tube, the viscosity of the fluid in the tube being measured as a function of the frequency of the oscillations in the fluid. The fluid circuit is described as containing transformer oil but gaseous hydrogen, nitrogen and carbon dioxide are also referred to as suitable for use. The tube 2 itself may not form the restriction in the circuit if desired a separate restriction being provided in the tube.

Abstract: 327,079. Sharples Specialty Co., and Jones, L. D. July 11, 1929. Strainer separators, discharging.-The wall of a bowl used for separating liquids from solids has elongated slots with their longer dimension in the direction of rotation; the bowl is constructed to oppose the flow of liquid in the direction in which the solids move and it has cleaning members extending into the slots. In the form shown in Fig. 1 the bowl 10 is made up of a number of rings 6 screwed to longitudinal arms 7 attached at their upper ends to a ring 8 and at their lower ends to a ring 9 secured to a rim 21 attached to the hub 23 on the hollow shaft 1 by arms 22. The cover 65 of the drum is secured to the ring 8 and has a central aperture for the passage of the supply pipe 34. The inner surface of the bowl is frusto-conical and a helical blade 70 carried on a shaft 2 is rotated at a different rate from the bowl so that the solids are fed for. ward to be discharged between the arms 22. The liquid passes through the endless slots 30 formed between the rings 6. Slot clearing members 52 are pivoted to the blade 70 and swing outwards under centrifugal force to prevent any solids from accumulating on the slots. A plate 146 distributes the mixture as it emerges from the pipe 34. In the modification shown in Figs. 2, 3, 8, the bowl is carried by the hollow shaft 11 and consists of rings secured to longitudinal arms 17. The bowl as a whole is divergent in the direction in which the solids move, but the inner surface of each ring slopes oppositely to the slope of the bowl. The height of each step thus formed is inversely proportional to its mean diameter. The material from the tube 34 is distributed, by the plate 46 and the solids are moved from each ring by plough-like members 38 on the cone-shaped member 12 on the shaft 13. The liquid discharge outlets are kept free from solids by members 52 which enter the slots 30 and the edge 55 of the projecting part 54 on each member 52 traverses the sloping face of the bowl ring. In another modification the bowl, which is divergent in the direction in which the solids move, consists of rings which are divergent in the same direction. The greatest diameter of any one ring however is greater than the least diameter of the next so that a number of steps is formed.

Abstract: 386,260. Wire resistances ; couplings. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Abbott, C. C. ; 240, 2nd Street, Pittsfield, Massachusetts, U.S.A.) July 29, 1932, No. 21480. Convention date, July 30, 1931. [Classes 37 and 38 (i).] A terminal member is secured to a resistance element by forming a longitudinal hole through the terminal, enlarging the hole at one end to form a recess, inserting the end of the resistance element into the hole so that it extends through the terminal into the recess, and then filling the recess with conducting material such as solder. In the construction of heating resistance shown in Fig. 2 the resistance wire 10 is embedded in compacted powdered refractory insulating material 13, such as magnesium oxide, within a metallic sheath 11. Secured to each end of the resistance wire 10 is a terminal 14 passing through an insulator 16 which may be made of green lava. A terminal insulating block 22 of porcelain &c., may be provided at each end of the heater and may have a reduced portion 22a which enters a corresponding recess in the insulator 16. The terminals 14 have threaded ends which project through the insulators 22 and to which are screwed connectors 26 secured to supply leads 28. Protective casing members 30 for the terminals are secured to the end of the sheath, for example, by a screwed connection and a set-screw 31. These members may also be threaded at 30a for mounting in a framework. Each terminal 14 is of tubular form with an enlarged portion 14b and is counterbored at each end to form recesses communicating with the longitudinal hole. A slot 35 extending throughout a considerable part of the length of the terminal also communicates with the axial hole. The straight end portion of the resistance wire 10 is inserted in the axial hole of the terminal 14 and brazed thereto through the end recesses and the slot 35. Silver solder may be employed as the brazing material. The end of the terminal is then threaded and the resistance wire 10 with its terminals is assembled within the sheath 11 which is then filled with powdered magnesium oxide and swaged down. The connectors 26 are secured to the bared ends of the leads 28 by swaging and after the connectors are screwed on to the terminals 14 holes 56 are formed through which silver solder or other brazing material is applied and the connector 26 and terminal 14 are brazed together. In a modification, Fig. 10, both leads 73 are brought out at the same end of the unit. The resistance wire 60 is wound in a double helix on an insulating core 61 and is'supported in cup-shaped insulators 63, 64 at opposite ends of the sheath 65. The terminals 67, 68 project through the insulator 64, and are further insulated from each other by mica sleeves 70, extending into the insulators 64, 72, and by a triangular piece of mica 75, of which the base is held in a slot in the insulator 72 and the apex secured by asbestos thread 77.
