Title: Improvements in or relating to check valves for inflatable or expansible enclosures
IPC: F16K15/20
Filed: 1957-06-05
Abstract: 860,269. Valves. REGIE NATIONALE DES USINES RENAULT. June 5, 1957 [June 28, 1956; Jan. 31, 1957], No. 28067/60. Divided out of 860,268. Class 135.  An elastomeric inflation valve for expansible enclosure, e.g. a tyre, comprises a first tubular body part 35 with a flange 36 and a second body part 40 with a flange 41 and a conical boss 42, the two flanges having the enclosure wall interposed therebetween and the boss 42 accommodating a projection 43 of the body part 40. The boss incorporates a ring of orifices 44, the inner ends of which are normally sealed from the boss in body part 35 by a bead urged against the adjacent end of the projection 43 due to prestressing of the boss 42. Upon removing a ribbed plug 39 from the part 35 and supplying pressure air to the latter, the boss 42 is distended and uncovers the ends of the orifices 44, enabling the air to pass into the enclosure. When the supply of air ceases the boss returns to the position shown due to its elasticity and the pressure in the enclosure. A tube 47, Fig. 4, may be provided for insertion into the part 35 to unseat the boss, the outer end of the tube being connected either to a source of pressure, e.g. a pump or a pressure gauge; the tube may also be used to deflate the enclosure. In another embodiment a two-part valve body 59, 60, Fig. 5, of metal or plastic holds closure member 55 in position through a bead 61; the closure member may be of rubber or plastic and is prestressed. A depression at the inner end of the supply passage 64 provides a seat for a central semi-spherical protrusion 56 of the closure member between which and the bead 61 are two smaller sealing protrusions 57, 58 and orifices 67 ; the member 55 may incorporate grooves 70 in the surface which cooperate with the body part 60. Upon supplying pressure air to the passage 64, the protrusions 56, 57, 58 lift in sequence to admit air to the enclosure through the orifices 67. The enclosure cannot be deflated since a tube introduced into the passage 64 will only lift the central protrusion.

Title: Production of multi-component fibres
IPC: D01D5/32
Filed: 1965-07-02
Abstract: 1,106,849. Conjugate filaments. JAPAN EXLAN CO. Ltd. 2 July, 1965 [2 July, 1964], No. 28243/65. Heading B5B. In a method of spinning multicomponent fibres from two different materials by extruding them through a common orifice, the two materials are partly intermingled at the interfacial area between them by causing the two streams of the materials to meet or collide with each other at an obtuse angle or at 180 degrees to produce a turbulent flow prior to extrusion through the orifice. Apparatus comprises means for supplying the two materials to first channels, which merge by second channels into a common passage communicating with an orifice, the second channels being narrower than the first channels, and meeting at an obtuse angle or at 180 degrees at the common passage. In one embodiment (Figs. 1 and 3), a spinneret plate 2, provided with rows of orifices 1 is mounted on guide plate 4 having passages 3 in the same number of rows as the orifices. Spinning solutions are supplied to separate chambers on the inlet section of sleeve 5, which is provided, at its outlet, with narrow first channels 12, 12<SP>1</SP> defined by partitions 11, the arrangement being such that the two spinning solutions are supplied to alternate channels. In operation, the spinning solutions flowing down alternate channels 12, 12<SP>1</SP> pass into second channels 13, 13<SP>1</SP>, where turbulence is created, and thence, in laminar flow, with a partly intermingled or blended interface, through common passage 3 to the orifices 1. In Fig. 3, between the second channels 13, 13<SP>1</SP> is 180 degrees. In a further embodiment (not shown), an enlarged space (14) is provided at the junction of channels 13, 13<SP>1</SP> to promote intermingling. The conjugate fibres so produced have a reduced tendency to datamination. In an Example, 10% solutions of two acrylonitrile/methyl acrylate copolymers in 45% aqueous sodium thiocyanate are spun, using the apparatus of Fig. 3, into 10% aqueous sodium thiocyanate at - 3‹ C.

Filed: 1931-10-12
Abstract: 380,961. Checking receipts. MONHEIM, L. [Firm of], 131, Gustav-Adolfstrasse, Weissensee, Berlin. Oct. 12, 1931, No. 28314. Convention date, Aug. 7. [Class 106 (i).] Differently shaped or coloured tokens indicative of values are released by chance by the salesman or customer and become visible in a trap preliminary to their delivery to the outside of the apparatus or back to the interior of the apparatus, the delivery of a token being dependent upon the cooperation of a further token which remains in a trap after the delivery. In the form shown the tokens such as balls are contained in holes in a plate 2 above and below which are sheets of paper 31, 3<11> for the purpose of covering and retaining the balls respectively. The salesman using a punch pierces the upper sheet to force a token through the lower sheet on to an inclined plate whence the ball rolls to a glasscovered pocket 12, where it is retained by a lip 10. If the customer is prepared to purchase an article at the price indicated by the colour of the token the transaction is performed and the customer may then release a further token. By rocking a shaft 17 the salesman may slide a plate 13 and through an arm 21 displace the tokens to the left, Fig. 4, the first token being thus pushed beyond the lip to escape through a hole 14 in the plate to a pocket 22 in the head 20 of the shaft and thence to an open cup 23. If desired the token after exposure at 12 may be transferred by the pocket 22 to a shoot 25 leading to a further position of exposure. At each rocking of the shaft, a pin 26 raises a shutter 30 to let the exposed ball escape back to the inside of the casing and so make way for the succeeding token being transferred by the pocket 22.

Title: Improvements in water tube boilers
IPC: F22B17/10
Filed: 1924-11-26
Abstract: 245,562. Burkhardt, G. Nov. 26, 1924. Water-tube boilers.-In a water-tube boiler, an upper drum is connected to a lower drum by a number of curved tubes some of which lie in planes inclined to the others, so that the hot gases flow lengthwise along the tubes and the streams are caused to intersect. The banks of tubes 3, 4, Fig. 1, connecting the drums 1, 2 are bent in circular arcs which intersect at points 5, 6, 7. 8, so that the tubes can be inserted through holes at these points. The tubes in each bank are in two series, a, b, Fig. 2, the planes of which are inclined on opposite sides of a plane at right angles to the two drums. The hot gases flowing longitudinally through each bank of tubes are thus divided into streams which are caused to intersect twice. The main deflection of the gases is produced by plates 17<1>. The tubes may alternatively be of S or zig-zag shape, so that a number of crossings of the streams of gases are obtained. In a modification. Fig. 5, the lower drum may be replaced by a header 24, preferably of circular cross-section. The diameter of the descending tubes may be less than that of the ascending tubes, or the number of tubes may be less. In another modification. there may be two upper drums and two pairs of intersecting banks of tubes, so that the weakening of each drum by the tube holes is decreased. In another modification, Fig. 7, upper and lower headers 23, 24, may be employed instead of drums, and an upper drum 28 outside the setting mav be connected by tubes 25, 26, 27 to the upper header, for the upward passage of steam, while smaller tubes 29 are provided for the passage of water. The upper headers may be provided with semi-circular troughs 39, Fig. 13, to convey the water across from the tubes 38 without interference from the rising steam bubbles. The headers 23, 24, Fig. 7, are protected from the hot gases by shields 32, 33.

Abstract: 871,226. Facsimile recording surfaces. TIMES FACSIMILE CORPORATION. Sept. 5, 1958, No. 28596/58. Class 40(3) A recording blank for use in a spark discharge type of facsimile recorder comprises a base member 10 (Figs. 1 and 3) carrying two electrically conductive layers 11a, 11b, the first comprising a dried solution containing powdered carbon, a transferable colouring ingredient and a waxlike ingredient which flows freely when heated and the second comprising a dried binder solution containing powdered carbon covered by a thin masking coat 12. The surface resistance of layer 11a is lower than that of the combined surfaces so that when a recording is made the spark discharge produces punctures 18 in layer 11b (and layer 12) only. To transfer such a record to a transfer surface the latter is placed in contact with surface 11b of the recorded blank and the 'sandwich' passed through heated rollers (Fig. 4, not shown) the resulting flow of the waxlike ingredient carrying the colouring ingredient through the punctures 18 to the transfer surface. The transfer copy, which appears as a mirror image of the first, may thus be used as duplicating masters by means of a spirit or water copying process. The Specification includes details of the chemical composition and preparation of the layers 11a, 11b.
