IPC: E21D11/22
Filed: 1933-01-26
Abstract: 400,468. Mine-roof supports. RICHARDS, F., 14, Brynheulog Street, Port Talbot, Glamorgan. Jan. 26, 1933, No. 2490. Addition to 390,959. [Class 20 (ii).] The fish-plate joint described in the parent Specification is provided with an additional support in the transverse plane centrally between the abutting ends of the mine arches, props, cambered bars, or the like, and between the end supports of the fish-plates. According to one construction, the fish-plate is provided with end notches 1, Fig. 1, and central notches 2 which are adapted to receive U-shaped clamping bolts in the manner described in the parent Specification. In a modification, the fish-plates have holed lugs 8, Fig. 5, for receiving upper and lower cross bolts. In place of the central lugs and cross bolts, each fish-plate may be provided with a central elongated hole 9 for the reception of a securing bolt. In order to allow for movement of the bolt when the prop or the like is subjected to excessive pressure, the webs of the prop adjacent the joint are notched in elliptical fomation.

Abstract: 1302132 Finishing fabrics C EKELUND 19 Jan 1971 [2 Feb 1970] 2509/71 Heading DIS Apparatus for slitting a tubular knitted or woven fabric longitudinally along a predetermined marking and converting it to open width form comprises a platform 1, rotatable about a vertical axis, for supporting a container from which the tubular fabric to be slit is drawn; platform control means 3, 16, 4, 5 enabling the orientation of the platform to be varied by rotation about the axis as necessary to enable the fabric to be drawn from the container with its marking in a constant disposition; an internal spreader 6, of conical configuration, disposed above the platform 1 with its apex directed downwards for the fabric to be drawn thereon from the container, the spreader 6 being mounted for rotation about a vertical axis; a severing device 7 disposed adjacent the spreader 6 for severing the fabric as it is drawn up the spreader; control means 17, 18, 19, 20 enabling the orientation of the spreader 6 to be varied by rotation about its vertical axis as necessary to enable the fabric thereon to be maintained with its marking in accurate register with the device 7; and means for drawing the slit-open fabric away from the spreader 6. As shown, a ramp 2 facilitates the positioning of a container on the circular platform 1 which is coupled by a chain 5 to a reversible drive motor 4. Depression of one of pedals 3, 16 by the operator causes slow rotation of the platform in one direction and depression of the other pedal causes slow rotation in the other direction. The spreader 6 is of skeletal configuration and has a generally spherical skeletal lead-on head. The spreader 6 is rotatable about a vertical direction by a handwheel 17 or filler through chains 18, 20 and a spindle 19. The device 7 is adjustable in position by an arrangement 8. After slitting, the fabric is opened by a spreader 9 comprising a bowed bar and passes over driven rollers 10, 11, an idler roller 12, a spreader roller 13 having oppositely directed spiral arrays of projections thereon, a driven roller 14 and a folding arm 15 to lay the fabric in zig-zag folds on a table or trolley (not shown). Alternatively, the arm 15 is omitted and fabric is wound on a take-up beam (not shown). In initially threading- through the fabric, a lead-in paper web, secured to the leading end of the fabric, may be used. The severance marking of the fabric may be knitted-in or woven-in or subsequently applied. In a modification (not shown), a photoelectric sensor is provided adjacent the spreader 6 to sense the severance marking and provide signals to a motor to adjust the position of the spreader 6.

Abstract: 1,181,363. Wet separating. NATIONAL RESEARCH DEVELOPMENT CORP. 3 Feb., 1967 [21 Jan., 1966], No. 2828/66. Headings B1D and B2H. [Also in Division D1] Fibres, for example asbestos fibres or silicon nitride whiskers, are classified for length by passing a liquid dispersion of the fibres onto a circulating endless screen having a mesh size such that the longer fibres are retained thereon and the shorter fibres pass therethrough with the liquid, and removing the fibres retained on the screen by flushing a liquid therethrough. The screen may be formed by a horizontal rotating cylinder, the fibres dispersion being fed tangentially onto the inside of the cylinder at the bottom with the retained fibres being flushed from the cylinder at the top. A second cylinder of larger diameter than the first but of similar mesh size may be arranged coaxially around the first cylinder to re-classify the fibres passing through the first cylinder. The liquid may contain a wetting agent. The fibres passing through the screen or retained thereon may be classified again using a screen of different mesh. The length classification may be preceded by a diameter classification using a hydrocyclone or an elutriation column.

Abstract: 632,086. Treating sugar massecuite. FLETCHER & CO., Ltd., G., and MURRAY, C. W. Jan. 30, 1947, No. 2868. [Class 127] In a process for the treatment of sugar massecuite, substantially separate or isolated charges of massecuite are individually reheated immediately prior to the charging of said reheated charges to individual centrifugal separators for the separation of sugar crystals therefrom. The process may be carried out in an apparatus as shown in which a container 1 is divided into compartments 2 each having a valved outlet 4, by baffles 3 which may be fixed to the casing 1 or annular baffle plates may be disposed around and carried on the drum 9 to rotate therewith. The drum 9 extending throughout the length of the container 1 has external paddles 10 constituting two interrupted helices of opposite hands and has inside a smaller drum 11 subdivided by a partition 12 while the annular space between 9 and 11 is subdivided into longitudinal spaces. Steam or other heating medium is supplied by pipe 17 and discharged from pipe 23, the pipe 21 being for the discharge of condensate. The massecuite is maintained above the level of the baffles 3 and as it is drawn off through the outlets 4 after being heated by the passage of steam through the drum more cold massecuite falls into the appropriate compartment.

Abstract: 253,826. Claus, B. Feb. 2, 1926. Arc lamps.-In arc lamps wherein an auxiliary incandescing body is heated by the light source, substantially all the heat radiated by the arc is concentrated on to the body by means of a reflector or lens or both. In the lamp shown in Fig. 1, the reflector a<1> is formed on the surface of an ellipsoidal bulb and is adapted to reflect all the heat from the filament or arc b to a refractory body c placed at opposite foci. Both a heat source and a body c may be placed at each focus. In the lamp shown in Fig. 5, the heat from two sources b<1>, b<2> is concentrated upon one body c by two rejectors a<1>, a<11>. The shape of the reflector may be such that the heat source b and the body c are nearly coincident, as shown in Fig. 8. The upper part of the bulb may be shaped as the heat reflector, and the lower part to suit the light source, as shown in Figs. 12 and 15, the part a<4> of the bulb being formed as a light reflector. The upper part of the bulb may be sealed off from the lower by a heat-transmitting partition or lens f, the lower part a<3> being removably secured to the upper by a screw or other union g and left filled with air.
