Filed: 1939-03-21
Abstract: 526,767. Heat insulation. MAINELLI, A. March 21, 1939, No. 8925. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 27, 1939] [Class 64 (ii)] Thermal insulation comprises one or more corrugated or undulating layers and one or more layers of tubes. A pipe 1 is surrounded by an inner corrugated layer 2, an intermediate layer of tubes 3, and an outer corrugated layer 4. Plain cylindrical sheets 5 are arranged between the layers and may enclose the whole packing. Paper sheets, fireproofed and waterproofed, are used, and aluminium sheets may be glued to the paper. The Specification as open to inspection under Sect. 91 described the use of tubes alone and corrugated sheets alone to form a cover with numerous air or beehive-like spaces. This subject-matter does not appear in the Specification as accepted.

Abstract: 539,601. Sliding clasp fasteners. AERO ZIPP FASTENERS, Ltd., and MEITNER, B. May 20, 1940, No. 8929. [Class 44] The fastener members of a sliding clasp fastener are formed with longitudinal channels merging into laterally off-set channels, and are mounted in spaced relationship on a carrier of string, wire, ribbon or the like threaded through the channels, the carrier portions between the spaced members being secured to the stringer tape. As shown, the members are of generally cylindical shape, rounded or conical at one end 11 and with a correspondingly shaped recess 12 at the other so that adjacent members can rest together in interlocking relationship. Each member has an axial bore 10 merging into lateral branches 13, 14 so that the members can be threaded on to a string or like carrier 15 or 16 which is then secured to the edge of a stringer tape 1; 2 with the fastener members in the requisite spaced relationship. Fig. 8 shows the carriers 15, 16 secured to the tapes 1, 2 respectively by stitches. Fig. 7 shows an alternative in which the carrier is received in the bight of a folded perforated tape 20, with the members projecting from the perforations. In an alternative the carrier is woven into the tape. The members may be of any suitable material, metal, glass, wood and ceramic material being mentioned.

Title: Plant for the centrifugal casting of hollow bodies or of covering, protecting or similar layers in hollow bodies
IPC: B22D13/02
Filed: 1955-03-28
Abstract: 776,091. Centrifugal casting of concrete &c. BUDERUS'SCHE EISENWERKE, and STANTON IRONWORKS CO., Ltd. March 28, 1955 [Dec. 27, 1954], No. 9006/55. Class 87(2). [Also in Group XXII] A centrifugal casting plant for concrete &c. has separate stations for the three operations of firstly beginning acceleration of the moulds or hollow bodies to casting speed, secondly introducing the concrete into the moulds or hollow bodies, and thirdly continuing rotation of the moulds or hollow bodies until the concrete has solidified, and the moulds or hollow bodies are transferred from station to station between the three operations by transfer rollers on movable axes which rise and fall during transfer. At each working station 4, 5, 6 there are several pairs of rollers distributed over the length of the mould 1, those at station 5 being driven while those at stations 4 and 6 are idle. The transfer device comprises pairs of rollers 8, 9 rotatably mounted on bars 15 pivoted to arms 10 journalled in housings 11 and continuously rotated by a drive 12. As the arms 10 rotate the rollers 8, 9, engage the mould at station 4 which is stationary and the mould at station 5 which is rotating at casting speed and supplied with concrete. The mould at station 6 which is continuing to rotate after casting is engaged by fixed supporting surfaces 14. As the arms continue to rotate the moulds are lifted and transferred to the left. The mould at station 5 transfers its rotary motion through rollers 8, 9 and chain drive 13 to the mould at station 4 which is thus accelerated from rest, and as soon as it is lowered on to the rollers at the station 5 it is accelerated to casting speed. The arms 10 may have an oscillatory motion. Specification 632,104 [Group XXII], is referred to.

Abstract: 139,339. Sieber Products Manufacturing Co., (Assignees of Rubin, A.). Feb. 26, 1919, [Convention date]. Covers; clamping-bars. -The back of a loose-leaf binder of the flexibleband type is composed of two or more rigid sections E, E<1> hinged ' together, so that the back has sufficient flexibility to allow the clamping-bars A, A<1> to approach each other, when the binder is opened, and thus slacken the tapes or bands C enough to permit the leaves to spread out flat. The sections E, E<1> and the covers F, F<1> are hinged on pins 4, on which also the clamping-bars A, A<1> are mounted so that they can rock relatively to the back and thus do not obstruct the leaves from opening out flat. The clamping-bars A, A' are angular in cross-section, providing a portion to bear against the rear edges of some of the leaves.

Abstract: 711,703. Turbine and compressor blades. ROLLS-ROYCE, Ltd. July 16, 1952 [April 18, 1951; Sept. 6, 1951], Nos. 9112/51 and 21111/51. Class 110(3) [Also in Group XXII] A blading element for compressors or turbines of gas turbine engines comprises as a unit a pair of complete profile portions constituting the working portions of a pair of adjacent blades and an interconnecting U-shaped portion affording, the means by which the blading element is secured in position in associated structure. The interconnecting portion is shaped so that when the element is secured in position, the edges of the interconnecting portion are contained in planes normal to the rotor axis of the compressor or turbine and the junctions between the blade profile and interconnecting portions lie substantially in the surface of the supporting structure and extend across the surface in directions skewed with respect to the rotor axis. The element may comprise a pair of aerofoil-section profile portions 12 and an interconnecting U-shaped portion 13 of uniform crosssection. The blading elements are mounted in a circumferential channel 11 in the periphery of a rotor disc 10. the sides of the channel having grooves 11a to engage corresponding projections 14a on the sides of locking pieces 14 which are mounted both within the limbs of the U-shaped portions of each element and between adjacent blading elements. The locking pieces are inserted in a widened portion of the circumferential channel 11, the widened portion being subsequently closed by a locking piece retained in position for example by means of a set screw. In the embodiment shown in Fig. 13, the locking pieces 14 are of parallelogram shape, and are inserted together with an associated blading element into the circumferential channel 11, the locking pieces then being turned as indicated by the arrows 21 so that the projections 14a engage the corresponding grooves in the channel, no widened entry opening being necessary in this embodiment. In a further embodiment, locking pieces are not provided and the blading elements are retained in position by bolts or pins passing through the U-shaped interconnector portions, ring-shaped filler pieces being disposed within the U-shaped portions and between the U-shaped portions of adjacent blade elements. The blading elements may be constructed from strips of flat sheet metal, the end portions being formed into aerofoil section and the strips then being bent to form the U-shaped interconnectors. Alternatively, they may be formed from a tube, the end portions of which are first formed into aerofoil section before being bent to form the U- shaped interconnector portions, or hollow blade portions may be mounted on the ends of U-shaped interconnector portions.

IPC: D01C1/02
Filed: 1923-04-03
Abstract: 211,739. Postiglione, M. April 3, 1923. Retting.-In a method of treating textile plants for extracting the fibres, the plants are dipped for 20 minutes in a boiling bath containing a weak solution of sodium bicarbonate and neutral calcium carbonate, the bark and the ligneous part are then separated from the alburnum or fibrous part, after which the stalks are passed between pairs of cylinders whereby the ligneous part breaks up and falls out. The stalks are then immersed in a second stronger solution of the same substances and de-gumming is effected, the gum being transformed into a mucilage, which is expelled by a squeezing machine, leaving the strands or fibres quite free and having maximum length, strength and brilliance. Flax, hemp, and the like, and the branches of the mulberry tree may be treated as above: agave and like pulpy material is first dried, or the pulp removed mechanically.
