Title: Cooling systems for conductor-cooled dynamoelectric machines
IPC: H02K9/19
Filed: 1959-10-09
Abstract: 922,695. Cooling systems for dynamo-electric machines. GENERAL ELECTRIC CO. Oct. 9, 1959 [Oct. 21, 1958], No. 34285/59. Class 64 (3). In a cooling system for a dynamo-electric machine such as a generator, a coolant liquid which may be water or a suitable ethylene glycol, fluor-carbon or silicone is circulated through cooling passages 1a, 2a formed in the stator and/or rotor windings at a pressure such that the coolant is maintained above a minimum pressure corresponding to a liquid coolant boiling point which is higher than the temperature of the coolant, so that the coolant does not tend to vaporize and always remains in a liquid state at least throughout the windings. The coolant is preferably circulated by a pump 4 and the coolant circuit may include a heatexchanger 5 and a closed reservoir 3 in which a pressurizing gas such as nitrogen or hydrogen is maintained in a space 3b above the liquid level therein, the pressure being variable by means of a valve 3d. Alternatively, a variable displacement member such as a gas, water or oil-filled bellows 10 may be used to maintain the pressure in the system, a regulating valve 10b being incorporated in the fluid supply line to the bellows. A booster pump 9 may be employed to provide a greatly increased fluid pressure in the portion of the coolant supplied to the rotor 1 to counteract centrifugal effects. Valves 8c, 8e, 1#, 2e are incorporated in the circuit at the coolant inlet to and outlet from the windings to enable the pressure differential between the rotor and stator to be maintained. Pressures of from 60 to 100 pounds per square inch in the stator passages and from 150 to 300 pounds per square inch in the rotor passages are mentioned. In the system shown, the whole of the circuit is pressurized but in a further system described (Fig. 2, not shown), in which pressure is maintained by pumps, only the generator passages are subjected to elevated pressure whilst the remainder of the circuit including the reservoir 3 is at or only slightly above atmospheric pressure. A vapour extractor is then provided to remove non- condensible gases from the reservoir. The liquid cooling system of the invention may be applied to one only of the generator components (stator or rotor), the other component being gas-cooled using a conventional hydrogen ventilating system.

Abstract: 984,465. Surgical bandages. BAKA MANUFACTURING CO. Inc. Sept. 7, 1962 [Sept. 8, 1961], No. 34423/62. Heading A5R. A binder or elastic bandage adapted to encircle part of the body of a wearer is made of at least two panels of material stretchable in the encircling direction and joined by non- stretchable means which permits the panels to move relatively to each other perpendicular to the direction of stretch. In a wrist band constructed in this way two panels 60, 62 of material capable of stretching in a direction around the wrist, are each joined at their ends by a seam 68 to form closed bands and are joined to each other, with a slight spacing, by diagonal stitching 64. When the wrist is flexed the panels are permitted to move slightly towards or away from each other without changing their original positions on the wrist so that the bandage does not tend to move as a whole one way or the other. The same principle may be applied to a trunk binder made, in effect, from three vertically spaced, parallel panels, joined by stitching in the same way. Such a binder may have rows of hook and eye fasteners to facilitate putting on and taking off.

Abstract: 654,394. Inductance, capacitance and Q-value measuring. MERCIER, M. A. Dec. 30, 1947, No. 34780. Convention date, Jan. 9, 1942. [Class 37] A variable oscillator feeds a tuned circuit which includes the element to be measured, the output being applied to a detector adapted to indicate the maximum value of output, the tuned circuit comprising a fixed component, an adjusting component and a vernier adjusting component. A. variable oscillator 0 modulated by a tone frequency from H supplies a circuit formed by an unknown inductance Lx in parallel with a condenser C, a variable condenser C1 and a vernier condenser C2, and the oscillator is varied until it supplies oscillations of the frequency to which the circuit Lx, C, C1 and C2 is resonant, as shown by maximum response at T or E; the value of the inductance is then read from the dial of the oscillator M. To measure variations of further inductances, they are each inserted in place of Lx and the oscillator M maintained constant while C2 is varied to produce maximum response, C2 being calibrated to indicate percentage variation. The inductance may be replaced by an unknown condenser, and the condensers by suitable inductances, Fig. 2, not shown. The circuits for measuring inductance or capacity may be connected at will to the oscillators and detector circuits, Fig. 3, not shown. If the power of the oscillator is maintained constant, inductances and capacities of similar value may be tested for their quality, i.e. their resistance, by comparison of the value of the maxima indicated at T or E. The oscillator M preferably has a series of adjacent ranges, Fig. 4, not shown.

Abstract: 1,174,437. Plastics bottle sealing apparatus. H. TATIBANA. 1 Aug., 1967 [25 Aug., 1966; 18 March, 1967], No. 35347/67. Headings B8C and B8D. Liquid filled plastics bottles having an upstanding neck are sealed by preheating the neck while raising the liquid level by pressing the bottle sides, and then shaping and sealing the neck by moulding means. Raising the level prevents neck heating below a desired level. Intermittent and continuously operating machines are described. In both embodiments, bottles are located between two rotating discs on a turret, one, 103, (213), Fig. 3 (not shown), supporting their bases and the other 105, (215<SP>1</SP>), having notches which receive a groove in the neck. The necks travel within a heated inverted arcuate channel 113, (251) extending over about 180 degrees of travel during which time a rod 115, (260) presses the body to raise the level. In the intermittent embodiment, each bottle halts beneath a vertically reciprocatable and rotating spindle 119, Fig. 213, having a concave mould end which shapes and seals in one operation. In the continuous machine, Figs. 5A, 5B, 5C, a rotating spindle 301 is mounted above each bottle and carries slidable on it a sleeve 315 bearing two mould halves 325 at the ends of leaf springs 323. The spindle end is concave and carries a ring 335. As the spindle descends, the sleeve 315 is arrested and the ring 335 causes the halves 325 to engage and preliminarily shape the neck. Further descent of the ring with the spindle releases the moulds and permits the spindle end to perform the final sealing and shaping.

Title: Process for the manufacture of structures of high tensile strength of low-pressure polyethylene
IPC: D01F6/04
Filed: 1958-11-06
Abstract: Structures of high tensile strength, e.g. filaments, ribbons or sheets, of polyethylene obtained by a low-pressure process are made by subjecting the structures to a preliminary stretching at a temperature within the range of 65 DEG -120 DEG C. and to a subsequent after-stretching at a temperature within the range of 80 DEG -135 DEG C. The second stretching step may be carried out at the same or a higher temperature than the first stretching stage.  The overall stretching ratio may be about 1 : 12 and the stretching may be performed in known manner, e.g. using air, steam or liquids as heat-transfer media.  Snubbing rollers may be used to localize the stretching.  In the examples a water-bath and heated metal surfaces are used to heat the yarn.  Specifications 799,392, 799,823 and 801,031 are referred to.

Title: Improvements relating to liquid level gauges of the transparent channel type
IPC: G01F23/02
Filed: 1935-12-27
Abstract: 466,669. Indicating liquid levels. ANGLO-IRANIAN OIL CO., Ltd., and HUBBARD, M. E. Dec. 27, 1935, No. 35837. [Class 123 (i)] In a liquid level gauge of the transparent column type for use with low-boiling liquids such as propane or butane, inaccuracy 'due to higher temperature in the gauge is avoided by admitting a cooling fluid to a chamber adjacent to the liquid column. The space a<2> is connected at each end to a storage tank, and is closed on one side by a glass strip b and on the other side by a partition a<1> separating it from a space a<3>. A small quantity of the volatile liquid in the tank-may be admitted through opening c<3> to space a<3> and its vaporization lowers the temperature of the indicating column a<2> so that a true level reading can be obtained. Alternatively, a continuous supply of cooling fluid, such as cold water, may be passed through the space a<3>. The Provisional Specification refers also to the provision of means for supplying heat to the gauge e.g. by electric heating, and to modifications in which the desired heat transfer is obtained by means of heatconducting material to which heat is supplied or from which it is abstracted.
