Filed: 1952-12-03
Abstract: In the machine for the liquid after-treatment of artificial threads described in the parent Specification, means is provided for heating or cooling the surface or surfaces used to supply processing liquid. Means may also be provided for heating or cooling the surface or surfaces used to remove the processing liquid, particularly where the treating liquid is being continuously circulated.  For heating the surface an electric heating element may be provided within a tube forming the surface, or a pipe may be fitted so that it projects into the tube so that a heating or cooling fluid may be passed continuously through the pipe and then withdrawn through the annular space between the inner pipe and the tube.  Alternatively the tube forming the surface may be part of a closed circuit through which a heating or cooling fluid is continuously pumped.  In this embodiment the liquid-removing surface may be part of the same closed circuit, e.g. by using a U-tube construction, the two arms of which function respectively as the liquid-applying and liquid-removing surfaces. The use of the heated liquid-applying surfaces of the invention, in addition to expediting the processing treatment, helps to maintain a humid atmosphere in the vicinity of the thread pack.

Title: Improvements in or relating to reinforced concrete piles, piers or the like
IPC: E02D5/46
Filed: 1932-11-02
Abstract: 407,769. Piles. BRITISH STEEL PILING CO., Ltd., 54A, Parliament Street, and HOOD, A., 181A, Adelaide Road, Hampstead, both in London. Nov. 2, 1932, No. 30928. [Class 68 (ii).] A concrete pile is made by threading precast hollow units on a central supporting pipe, positioning this in a bore, and supplying grout under pressure. As shown in Fig. 1, the bore a is lined with a removable sectional casing b. Precast' units c each with a central longitudinal hole d, are threaded on a tube e, which also is made in sections, each as long as two units c. The bottom section of the tube e has apertures m, and its lower end is closed by a plate f, with a flange g, which sets into a cup-like recess h in the base of the lowest unit c ; the walls of this recess have lateral passages k. During the assembly of the pile the lowest section e is supported by clamps p, which engage with the coupling.n while the next higher section e is joined thereto, and one or more units c are placed in position on hinged arms q attached to the head of the casing b. The weight of the assembled parts is then taken by the newly added length e, the clamps p are removed, and the parts raised until the upper end of the units c inside the tube engages with the underside of the newly added units. The arms q are then turned away, the parts lowered, and the process repeated. When it is desired to recover the tube sections e, all except the lowest are joined by right-hand threads ; the lowest is connected to the adjacent one by a left-hand thread, and, with the plate f, is abandoned. Units with their walls may be used for making the top end of the pile. In a modification, the units, Fig. 6, are made with a central hole d and additional holes t, and with helical reinforcements u. These units are assembled on sectional reinforcing rods placed in the holes t; these are recovered and replaced by continuous rods if there is sufficient head room. When the column has been assembled, the water within the casing is expelled by supplying air through the pipe e, Fig. 1, and cement grout is then supplied under pressure through the same pipe so as to fill all the spaces in and around the pile units while the casing a is extracted. For making a foot, a burstable container of, e.g. waterproof material, containing a cement mixture is placed in the bottom of the bore, and may be burst by using the assembled column as a ram. Specification 370,795 is referred to in the Provisional Specification.

[Class 78 (i)] In conveyer plant in which an endless belt conveyer is changed in direction by forming the belt into a scroll or helix by passing it round a guide, the latter is formed by a series of idler rollers of small diameter arranged to define the helical guide surface. Fig. 3 shows one example in which the belt A passes round the guide B, over a pulley C and then continues at right angles to its original direction. The material is dumped at the guide and received again on this second run of the belt. The guide shown in elevation in Fig. 6, comprises a number of barrel-shaped rollers 3 arranged in a helical path and each mounted on a swivel to adapt itself to the surface of the twisted belt. Fig. 9 illustrates the application to a mining conveyer wherein a single belt is used to collect material from the rear of the cutting-machine and also to convey it along the gate road E. In this case the top carrying run of the stretch A' delivers to the top run of the stretch A<SP>3</SP> at the scroll guide J and the return run after passing the end pulley 9 passes round a second scroll on the guide J and then continues as the return run of the stretch A<SP>1</SP> back to the cutting- machine. Fig. 10 shows the scroll guide employed in this latter arrangement. The run A<SP>1</SP> of the belt passes round the guide B, and the pulley 11 and then continues as the top run of the stretch A<SP>3</SP>. The return run A<SP>4</SP> passes round pulleys 12, 13 and thence round a second guide B<SP>1</SP> to emerge as the lower run of the stretch A<SP>1</SP>.
