Title: Papermaking method and apparatus
IPC: D21F1/00
Filed: 1964-01-20
Abstract: 1,025,777. Papermaking apparatus. HYUCK CORPORATION. Jan. 20, 1964 [Jan. 22, 1963], No. 2358/64. Heading D2A. The stretch characteristics of paper are improved by forming the paper on a stretchable Fourdrinier wire and continuously contracting the wire by a substantial amount while the paper web is in a non-fluid state in which the web sticks to the wire, thereby compacting successive portions of the web. The web may be compacted transversely and for longitudinally. In one example (Fig. 1.) wire 12 of nylon, polyester, acrylic, or copolymer fibres has relatively straight yarns in the crossdirection and relatively tortuous yarns in the machine direction so that as the wire is pulled over suction boxes 20, or other retarding members, the wire lengthens longitudinally, causing transverse contraction of the wire 12 and web 16 thereon. Wheels or rolls 34 acting outwards on each edge of the wire keep the wire at or above its normal width before suction boxes 20 are reached. The web may then pass to fabrics 38, 40, Fig. 3, which are stretched longitudinally before they clamp the web between roll 42 and roll 46. The tension in the fabrics decrease as they pass between clamping shoes 49 and 51, so that the fabrics and the web contract longitudinally. In this case-by for example making fabrics 38, 40 of elastic or stretch yarns-there is little lateral contraction of the fabrics when they are stretched longitudinally. The apparatus of Fig. 3 may constitute, or be placed before or after, the press-section of the machine. In another embodiment (Fig. 4 not shown) fabric 40 may be placed above wire 12 so that the web may be contracted in both directions while still on the wire. In this case wire 12 may be made of elastic or stretch yarns with the lateral contraction of the web obtained by first stretching the wire laterally by means of wheels or rolls 20, or wire 12 may be constructed as in Fig. 1, with rolls 44, 48 being placed close to rolls 42, 46 so that there is too short a distance during which the wire 12 and fabric 40 might expand laterally when they contract longitudinally. Alternatively fabric 40 may be omitted and wire 12 and web 16 passed to press rolls 42, 46, Fig. 5, and to roll 22/44 and drier 66 rotating at a slower peripheral speed than rolls 42 and 46.

Title: Improvements in furnace construction
IPC: F27D1/02
Filed: 1928-01-25
Abstract: 285,849. Detrick Co., M. H., (Assignees of Ellman, L.). Feb. 23, 1927, [Convention date]. Roofs; reverberatory furnaces.-A furnace roof is made up of a number of freely suspended sections which can swing both longitudinally and transversely of the roof without appreciable change of inclination, each section comprising a number of individually suspended refractories having end and side abutments with the refractories of adjacent sections. In the construction shown, which provides a flat roof for a reverberatory furnace, the refractories 17 are threaded on to supporting-bars 19 suspended by hangers from overhead beams 18, the arrangement being such that the roof structure is supported independently of the furnace walls. Each supporting-bar is formed with a deep web 19a having at its lower edge a wider ledge portion 19b for supporting the tiles 17, and at its upper edge suspension flanges 19<c> with depending stops 19<d>. Each of the marginal bars for the roof structure is formed at one end with a stop ledge 19<e> on each face and other portions 19f, with which engage a complementarily toothed end attachment 20, Fig. 6, having a tile-supporting ledge 20d and a depending stop 20<e>. At the other ends of the marginal bars, and at both ends of the intermediate bars, are lugs 19<g> for supporting end tile holders 21, which can be withdrawn vertically to allow the tiles supported by the bars to be removed. The suspension flanges 19<c> are engaged by hook members 25 with inwardly-turned jaws, and these are suspended from upper hook members 22, which are slotted to receive the ends of the bolts 24. The beams 18 are so positioned that the supporting-bolts 24 for the marginal sections are displaced from the vertical, and the weight of these sections will consequently tend to maintain the tiles in close contact. A tight joint between the roof and the furnace wall is made by loose refractory material 26, such as ground chrome ore, which may be retained in position by plates 27. The slots in the tiles, which accommodate the supporting-bars, are of dovetail form as shown in Fig. 13, and the reentrant portions 17<b> have a smaller radius than the convex portions 17<c>. The roof may be sloped downwards from the port ends of the furnace by adjusting the length of the bolts 24.

[Class 97 (ii).] In apparatus for indicating the inclination of boreholes adapted to be supported in the drill stem and comprising .a pendulum the upper end of which is adapted to contact with vertically movable recording means, a medium passed down the drill pipe operates the recording means which at the end of its movement releases locking devices. In the form shown, the inclinometer is contained in a fluid-tight capsule 1 8 supported b y spaced ribs 20 in a barrel 11 which is threaded to the drill pipe at the top and to the drill bit at the bottom. The capsule 18 is provided with a universal mounting for a pendulum 32 and with a packing gland plug 21 carrying a spring- urged plunger 46 to which is attached a head 50 and a cylindrical block 53 supporting a spherical cap 55 of soft metal serving as the recording element. In operation the drill is inserted in the borehole and the circulating fluid forced down the drill pipe. The pressure of the fluid acting on a leather washer 52 fixed to the head 50 depresses the plunger 46, thus pressing the recording element 55 into engagement with the pointed end 44 of an extension of the pendulum 32. Spring catches 69 engaging in notched grooves in the block 53 retain the plunger in the lowered position, keeping the pendulum clamped until the instrument is drawn to the surface. In a modification a mass dropped down the drill pipe may be used to depress the plunger. The capsule 18 is preferably filled before use with light oil which may escape through the check valve 70.
