Patent GB-210674-A (GB)
Title: Improved apparatus for the drying of wound yarns after liquid treatment thereof
IPC: F26B21/00
Filed: 1923-04-30
Abstract: 210,674. Brandwood, J., Brandwood, T., and Brandwood, J. April 30, 1923. Cops, balls, and naasses of material in compact form. - Yarns are dried by forcing or drawing hot air through them while they are supported in compact form upon perforated spindles 17, Figs. 1 and 2, the spindles being secured to hollow carriers 15 supported, without securing means, upon dishes 11 which are secured to flanges on the hot air pipes 8, 8<a> arranged within the drying-chamber The direction of the flow of air through the yarns may be reversed. A compressor 20 forces air through a heater 22 and a valve 27 into the drying-chamber from which it is exhausted through the yarns on the perforated spindles and the pipes 8, 8<a> by a vacuum pump 25 communicating with the pipes through valves 30 - - 36. To reverse the direction of the air, the valves 30 - - 36 are closed and the valves 28 - - 33 opened so that air passes into the pipes 8, 8<a> and thence through the perforated spindles and the yam to the atmosphere. In a modification, the vacuum pump is dispensed with. In another arrangement, an air blower is substituted for the compressor. The drying may be conducted at a temperature of 200‹ F. and a pressure of from 8 to 9 pounds per square inch. Specifications 190,760 and 210,661, [both in Class 15 (i), Dyeing &c., Apparatus for], are referred to.

Title: Improvements in Apparatus for Determining the Rate of Flow of Liquids Through Jet and Similar Orifices.
Inventor: PARNACOTT ALFRED EDMUND
IPC: G01F9/00
Filed: 1918-07-30
Abstract: 129,480. Parnacott, A. E. July 30, 1918. Automatic - feed weighers.-In apparatus for testing or determining the rate of flow of liquids through jet and similar orifices such as the orifices of petrol jet nipples of carburettors, the e liquid passing from a supply tank a is maintained at a constant head in a float chamber c and passes down tubes g, g<1> in the bottoms of which the nipples are secured. Beneath the nipples are pivoted funnels p either of which may be turned to direct the flow on to a weighing-plate n supported by a float r immersed in the testing liquid in a chamber s. An overflow s' leading from the bottom of the chamber s maintains the specific gravity of the liquid therein, the same as that flowing through the nipple. The surface of the weighing-plate is made with a long spiral path along which the liquid flows from the centre to the periphery, and the consequent depression of the weighing-plate is indicated on a dial plate v<1> in terms of the volume flowing in given time by means of an indicating hand operated by a chain connexion v<3> passing over a spiral cam. A chain x carries balance weights x<1> by varying which the range of the apparatus may be varied. The flow down the tubes g, g<1> is started or stopped by needle valves operated by cam levers k, and the liquid is returned from a collecting tank b to the supply tank a by means of a pump q.

Title: Control system
IPC: G21C7/12

Abstract: 793,771. Automatic control systems for nuclear reactors. WILSON, V. C., OVERBECK, W. P., SLOTIN, L., and FROMAN, D. K. April 25, 1946 [April 14, 1945], No. 12576/46. Drawings to Specification. Class 38 (4). [Also in Group XL (a)] In a nuclear reactor, the neutron density is automatically controlled by positioning rods of neutron-absorbing material within either a reactor consisting of uranium interspersed geometrically in a lattice structure in a graphite moderating body or a reactor in which deuterium oxide surrounds uranium rods. In both cases a safety rod of neutron-absorbing material is drawn into the reactor, by gravity, upon energization of electromagnetic retaining means. The neutron density measuring device comprises an ionization chamber containing BF 3,  Argon, Freon. In the automatic control system, a regulating rod of cadmium or boron is moved horizontally into or out of the pile on rollers by electric motors energized through grid-controlled thyratrons the bias voltage of which varies in correspondence with the pile neutron density as determined by the ionization chamber. A further control signal corresponding to the rate of change of neutron density is developed in a resistance, condenser network in the thyratron grid circuit and the datum level of operation of the control system is manually adjustable. The safety-rod, of cadmium or cadmium steel, is mounted horizontally, on rollers, and is moved into the pile on a track by a weight. Near the limit of the movement of the safety rod into the pile a braking force is applied to the sides of the rod by fixed brake shoes. The rod is moved out of the pile by an electrically-driven chain to which the rod may be engaged. In the event of an electric power failure, both the safety control rods are automatically drawn into the pile. Visual indication is given of the position of the control and safety-rods.

Title: Improvements in or relating to hydraulic drives
IPC: F04C14/22
Filed: 1951-05-29
Abstract: 690,528. Rotary pumps and engines. KLATTE, T. (trading as KLATTE, T. [Firm of]). May 29, 1951 [Oct. 15, 1948], No. 12594/51. Class 110(ii) [Also in Group XXIX] A pump of the n and n+ 1 lobe type has an outer ring 8, driven by the toothed rotor 5 which is mounted in a bush 10 in which the ring runs with a large clearance to allow free rotation. To vary the pump capacity, the bush 10, which is eccentric to the rotor, is rotated by means of an external handle to vary the amount of liquid flowing back from a delivery port 14 to a suction port 13 between the toothed rotors. When the bush 10 is rotated the centre of the ring 8 moves along an arc of a circle. With 90 degrees rotation of the bush, no liquid is pumped; for 180 degrees rotation the liquid flow through the pump is reversed. Fig. 5 shows another method of regulating the pump capacity by means of axial displacement of the toothed rotor 17 relatively to the outer toothed ring 28. This is effected through a coupling 18 under control of a lever 19. The two ends of the rotor 17 are sealed by rings 20, 21. Sealing is provided by means of rubber packing 27 and an end ring 21. Inlet and outlet ports connect with grooves 22, 23 through the sealing ring 20 by way of bores 24, 25. The ring 20 rotates in a housing 26. Chambers 29, 30, are connected to the suction side of the pump and a space 31 to the delivery side to balance axial loads on the rotor. In a hydraulic system the pump supplies an engine of a similar type, the pump delivery having a bypass valve which opens under excessive delivery pressure.

[Also in Group XL (a)] Coolant flow restrictors in a nuclear reactor are adjusted by means responsive to coolant temperature, to stabilize the coolant temperature. Fig. 2 shows a sleeve 22 which can slide but not rotate in a channel 10. The sleeve is supported by a tube 32 sliding on a rotatable stem 27, and the tube 32 is suspended from a stack of interconnected ceramic discs 25 and dished Nb washers 26 in a guide tube 34. A change in coolant temperature causes the stack to change in length so that the sleeve opens or closes ports 57, thus changing the rate of flow of the coolant and hence the temperature to which it is heated. Overriding control is provided by rotating stem 27 to move a threaded collar 46 along the stem. In another embodiment the stack of discs and washers is replaced by a bellows filled with liquid metal such as Pb or Na.

Abstract: 794,682. Portable containers; making cartons. JAGENBERG-WERKE AKT.-GES. April 26, 1956 [May 21, 1955], No. 12827/56. Classes 18 and 66. A conical paper or cardboard container 1, Fig. 2, is formed with a reduced portion 5 near its smaller end to define an internal shoulder 6 and the bottom is closed by an end closure 4 having a flanged edge 3 extending for substantially the whole length of said reduced portion 5 whereby on nesting such containers the bottom closure 4 of one will engage the shoulder 6 of another. The container 1 may also have a U-shaped fold at its base as shown in Fig. 1a. The container may be made by shaping a flat blank 1, Fig. 3, about a conical shaped mandrel 7 having at its upper end a reduced cylindrical extension 8. An annular member 9, Fig. 5, descends to shape the blank around the extension 8. An end blank 2 that is flat as shown in Fig. 6. or with turned down edges, is then placed on the end of the container 1 and a die 10 descends to press the blank 2 into the shape of a dished closure member, an annular member 11 moving downwardly at the same time to turn down the edges of the end closure as in Fig. 7. In a modified method, the use of the annular member 9 is avoided by using the annular member 11 not only to turn down the edges of the end closure as before but also to simultaneously shape the blank for the body 1 around the reduced, extension 8 of the mandrel.
