Title: Apparatus for making superheater tube elements
IPC: B21C37/28
Filed: 1928-03-14
Abstract: 313,552. English, W. E., and Hannan, J. R. March 14,1928. Tubes.-In apparatus for presenting the ends of two or more tube lengths to suitably disposed tube bend forming means the tubes are held more or less parallel in a longitudinal open ended tubular pipe holder carried by a dependent eye pivoting about a vertical axis from an overhead longitudinally moving carrier. The tubes x<1>, x<3> are clamped by jaws n to a tubular holder m mounted in extensions l of a bearing j suspended from a slide f movable along ways a supported by end frames b<1>, b<2>. The bearing j is pivoted for movement about a vertical axis to a member g<1> which is movable laterally by a spindle h and cam g<2> to one of two positions to bring the tube ends opposite either of two pairs of roughing and finishing dies of a hammer c driven by a motor y. Extensions o<1>, o<2> at the ends of the tubular holder m are provided with a second tubular member m<1> to accommodate another tube x<2> already joined to one of the tubes in the holder m, the weight of the member m<1> being counterbalanced by weights p<1>, p<2>. The slide f is traversed back and forth to present the tube ends to the various operating devices, such as the furnace u, apparatus u<1> for welding the adjacent ends to form the junction, and shearing trimmer u<2>, by means of a screw q operated by a wheel q<1> with handle q<2>. The wheel q<1> also engages frictionally a wheel r which has mounted on its shaft a friction disc r' adapted to be engaged by either of two coned friction wheels s<1>, s<2> driven by a pulley s<3> and belt from the shaft e. The wheels s<1>, s<2> are movable by levers t, t<1> adapted to engage spring catches t<2>, t<3> mounted on a member t<4> connected by nuts t<5> to the feed screw nut q' movable with slide f, such that the backward or forward movement of the slide f is started by hand rotation of the wheel q' in either direction and continued by the automatic engagement of either friction wheel s<1> or s<2> with the disc r<1>.

Title: Improvements in or relating to the production of metal phosphorodiamidates and their conversion to foamed products
Inventor: GREY JOHN
IPC: C08G79/10
Filed: 1963-03-01
Abstract: Anhydrous alkali metal phosphorodiamidates <FORM:1070013/C1/1> where M is an alkali metal are produced by reacting an alkali metal, or alkali metal compound, with an organo phosphorodiamidate in a dry, non-aqueous, polar solvent.  The organo phosphorodiamidate may be phenyl phosphorodiamidate, and the solvent may be an organic solvent which boils at 60-85 DEG  C., e.g. ethyl or methyl alcohol.  The mixture is stirred at 20-90 DEG  C. from 1 to 48 hours.  Anhydrous phosphorodiamidates of metals other than the alkali metals may be prepared by reacting an anhydrous metal (other than an alkali metal) salt, e.g. a water-soluble, zinc or alkaline earth metal salt, with an anhydrous alkali metal, e.g. sodium, phosphorodiamidate in a dry, non-aqueous, polar solvent.  The precipitated product is filtered off, washed with the solvent and dried over phosphorus pentoxide or in vacuo at 30-40 DEG  C.  The metal phosphorodiamidates may be heated to 125-900 DEG  C. in an atmosphere of nitrogen or ammonia to yield foamed, condensation polymers of low density, say 0.4-1.0 lb. per cubic foot, with the sodium salt, by the elimination of ammonia. A homogeneous mass of foamed polymer may alternatively be obtained by heating tablets of the anhydrous, metal phosphorodiamidate separately to form partially foamed, polymer bodies and a mass of the partially foamed polymer bodies is subsequently heated, e.g. in a graphitized metal tray, to complete foaming and to form a homogeneous mass.  Thus the phosphorodiamidates of zinc, calcium or strontium admixed with say 1% of magnesium stearate lubricant are compressed into cylindrical tablets at 2 tons per square inch after granulation and sieving.  The metal phosphorodiamidates or the foamed polymers may be heated at a temperature higher than that required for foaming, but not higher than 1050 DEG  C., to form a glassy material from which fibres may be drawn.

Title: Improvements in or relating to slatted floors, decks or the like

Filed: 1920-03-19
Abstract: 165,189. Gage, S., and London General Omnibus Co., Ltd. March 19, 1920. Treats.-Relates to slatted floors or decks of omnibuses and the like of the type in which the slats are attached to the undersurface or floor leading intervening gaps and without any obstruction projecting above the upper surface of the slats. According to the invention, the slats 18 are not secured directly to the floor, but are attached, for example by screws 19, to two or more rigid runners 16 which are secured only at a few points 17 of their length to the floor, thus avoiding the drilling of a large number of holes in the floor. The runners 16 preferably consist of thin metal strips adapted to enter recesses on the under faces of the slats, which are preferably of wood.

Title: Piezo-electric transducer and process for making the same
IPC: G01N29/24
Filed: 1957-03-13
Abstract: 843,827. Piezo-electric instruments. REALISATIONS ULTRASONIQUES. March 13, 1957 [March 14, 1956], No. 8271/57. Class 40 (4). [Also in Group XL (b)] Composite piezo-electric transducers comprising both transmitting and receiving elements are made by embedding a block of electroded piezo-electric material in an acoustic damping substance and then cutting through the block to obtain a number of elements which are maintained in a single assembly but are acoustically isolated by the damping substance. As shown, an electroded ceramic disc 1 is embedded in a mass 9 of " Araldite " (Registered Trade Mark) by a casting process and is subsequently subdivided by incisions 10. Leads 4, 5, 6, 7 are attached to the inner electroded surface 3 before the casting process. They may be attached by coating the surface 3 with a soft conductive substance in which the ends of the leads are embedded. This layer is subsequently hardened. A suitable substance for this purpose is a mixture of " Araldite " and powdered silver. The isolating block 9 may be provided with internal tubing for positioning the leads 4, 5, 6, 7. The tubes may subsequently be withdrawn or, if they are made of metal, may be left in position to act as screens. The incisions 10 may be filled with an acoustic damping medium e.g. a mixture of " Araldite " and sawdust. Damping may be further improved by giving a coarse grain to the faces of the piezoelectric block. In a modification (Fig. 3, not shown), the disc is divided into two adjacent spiral elements by a spiral incision. In a further modification (Fig. 4, not shown), the block is rectangular in plan and is cut by a zig-zag incision to form two interdigitated comb-like elements. Adjacent elements may be used respectively as transmitters and receivers in a transducer for testing solid materials. By polarizing the pairs of elements in opposite directions, direct coupling produced by electrical induction is brought into phase opposition to direct mechanical coupling whereby the two modes of coupling compensate each other. To reduce spurious echoes due to residual electrical coupling, the transmitting element may be rendered ineffective, e.g. by applying a saturating polarizing field, during periods when it is not transmitting. A further method consists in using a ceramic material which has no remanent polarization and applying a polarizing field alternately to the transmitting and receiving elements.

Projecting into the casings 9 so as to be edge-illuminated by lamps 14 contained therein is a transparent sheet 3 having a scored design 4 on its rear surface and a backing sheet 7 with an opal or matt surface. Sandwiched between them and rear illuminated by the sheet 7 is a map or inscription 5 on thin paper or other translucent material, Spacers 8 between the backing sheet 7 and the backboard 1 are provided and the backboard 1 has stiffening strips 2 fixed to each vertical edge. Ventilation holes are provided in the strip 13 above each lamp. The scored markings may be filled with fluorescent material and illuminated by ultraviolet light and, if desired, the edges of the scored sheet 3 and the backing sheet 7 may be sealed together and the space between evacuated. The scored design may have parts differently coloured or have the walls colour varnished, the separate colours being illuminated by appropriately coloured lamps mounted at different parts of the edge in the lamp housings.
