Filed: 1960-04-29
Abstract: 895,810. Forming glass fibres. WALLSTEN, H. April 29, 1960, No. 15084/60. Class 56. Fibres of thermoplastic material are produced by supplying molten material 14 continuously to the inside of a frusto-conical funnel 15 rotating about an axis which is horizontal or inclined towards its wide end, at a speed to project the material from the edge 16 of the cone as fibres which are carried away in an approximately horizontal direction by an annular gas flow, as from holes in a tubular ring 17. In the form shown molten material 11 is poured into a channel 12 from the end 13 of which it pours into the funnel. The channel is axially adjustable in a support 22. The funnel 15 is joined to a cylindrical portion 25 which is connected to an outer concentric member 23 supported in a bearing 18 and driven through a belt 19. The spokes connecting the members 23, 25 may be in the form of fan blades to produce a cooling air flow. In operation, the funnel 15 may be cooled until it is coated with a solidified layer of thermoplastic material, the adhesion of which may be increased by grooves or depressions formed on the inner surface. This surface may have a ceramic insulating coating. In another embodiment two concentric frusto-conical members 15 are used. The molten material is centrifuged from the inner one into the outer, larger, one which runs at higher speed.

Patent GB-710602-A (GB)
Title: Gas alarm
IPC: G01N25/46
Filed: 1952-06-18
Abstract: In gas alarms of the type in which the presence of a gas or gas mixtures likely to explode produces heat by catalysed oxidation near an expansion agent in the form of a volatile liquid in a sealed limb of a U-tube containing mercury which is thereby caused to move past electrical contacts connected with an <PICT:0710602/III/1> oral or other alarm system, the U-tube is provided with absorbing material in the upper part of one leg above a constriction, while the enlarged other leg of said U-tube is surrounded by insulating material kept in position by an outer glass cover.  In the preferred embodiment illustrated, a volatile liquid is absorbed in an absorbent 1b enclosed in the left-hand limb of a U-tube above a constriction 1a, and surrounded by a catalyst 3a.  When an explosive gas is present, heat is generated, the liquid volatizes and the mercury is forced past contacts B and A whereby circuits connected respectively with "ahead" and "full alarm" signals are completed.  The insulation 1c and the surrounding glass sheath protect the right-hand limb from heat radiation.  If the concentration of the gas is high so that the mercury column reaches the contact 4c a magnet coil 6 is energized and the core 9 attached to a double-armed lever is drawn into it.  A screening cap 10, from which heat can only escape by means of openings in the top, is also attached to said lever and is thereby lowered over the catalyst on to a sealing support 2 and prevents further heating which might lead to bursting of the U-tube or have other harmful effects.  On cooling, the mercury in tube 1 recedes, the coil is deenergized and the counter weight 8 raises the screening cap.  Alternatively the use of a lever may be obviated by attachment of the screening cap to the core of a magnet coil arranged directly above it.

Filed: 1931-05-28
Abstract: 379,689. Ironing-presses. BAKER, F. E., 531, North Geddes Street, Syracuse, New York, U.S.A, May 28, 1931, No. 15646. [Class 138 (ii).] The press head 4 and buck 5 are carried by separate frames both of which rest loosely on a table A or other flat surface. One of the frames remains stationary and the other is drawn forwardly from the rearmost position shown in dotted lines to a position shown in full lines wherein the head and buck are in registration, the head being subsequently lowered by a cam to the second position shown in dotted lines wherein it is in pressing engagement with the buck. The goods are placed on the buck when the head is in the rear position. The frame on which the head is supported comprises two spaced U-shaped transverse members 3 of which the upper limbs 15<11> are connected by long.tudinal cranked handle-bar 18 and the lower limbs 15<1> are connected by longitudinal shafts 16 on which wheels 17 are mounted. When the head frame is drawn forwardly the lower limbs of the U-members and the shafts and wheels 16, 17 pass beneath the longitudinal angle section bars 11 forming part of the buck frame which is provided with feet 10. The head is carried by the front ends of springs 19 of which the rear ends are anchored to the U-shaped members of the frame 3. The cam for forcing the head on to the buck comprises a longitudinal bar 24 provided with enlarged ends and a central operating handle 25. The ends of the cam bar 24 rest between discs 27 which are provided with a number of recesses of different depths in their upper faces and which are rotatably mounted on the upper face of the press head, and guide-plates 26 having upturned transverse flanges between which the upper limb of each U-shaped member of the frame 3 is freely slidable, the lower edges of the upper limbs travelling over balls held between upturned longitudinal flanges of the plates 26 and stops depending from the lower edges of the upper limbs. When the handle 25 is rotated counterclockwise the cam bar also rotates and the longitudinal edges of the enlarged ends engage the guide-plates 26 and the bottoms of predetermined recesses in the discs 27 resulting in the head being forced downwardly from its support into contact with the buck with a pressure dependent on the adjustment of the rotatable discs 27 which adjustment effects the positioning of a recess of appropriate depth in the path of the rear longitudinal edge of the enlarged end of the cam bar 24. The ends of the cam bar are guided by posts 30 secured to the press head. Excessive rearward movement of the frame 3 is prevented by a chain 36.

Title: Heterogenous nuclear reactor
IPC: G21C7/02
Filed: 1961-05-02
Abstract: 942,411. Nuclear reactors. ATOMENERGI A. B. May 2, 1961 [May 11, 1960], No. 15866/61. Heading G6C. A heterogeneous nuclear reactor using as fuel a natural or slightly enriched fissile material and with heavy water as coolant and moderator, arranged to be operated at a water temperature higher than 100‹C., preferably higher than 200‹C., has the fuel in the form of rods of substantially circular cross-section and a diameter of less than 20 mm, and which are arranged parallel or at an angle to the flow of water through the reactor, evenly distributed in direct contact with the water which serves both as coolant and moderator at the same time, and so spaced apart from each other that the ratio of the volume of water present in the reactor core to the volume of the fuel exceeds 5:1. The reactor shown in Fig. 1 has a pressure vessel 1 with a horizontal partition wall 5 defining a lower space in which the fuel columns 8 are situated and an upper space, the pressure in which can be increased by steam being blown in through a pipe 7 or decreased either by discharging steam through the pipe 7 or by spraying cold water in through a pipe system 6. The fuel columns 8, of square cross-section, secured to the partition wall 5 by pyramid-shaped holders 9, are arranged in contact with each other in a square pattern. Between certain sets of four adjacent fuel columns 8, spaces are left for the insertion of neutron-absorbing control rods 10. As seen in Fig. 3, the fuel columns 8 comprise lengthwise girders 12 and, at suitable intervals, plate-shaped holders 14 for securing the fuel rods 15 at both ends and at one or more points along their length. These holders 14 are perforated so that they do not noticeably impede the flow of water. Such a reactor is "self-regulating" since an increase in the temperature of the water reduces its moderating capacity, there being no delay in the selfregulation as with reactors in which the water first runs through conduits surrounding dusters of fuel rods as a coolant before flowing through a moderator chamber.
