Title: Process for producing by separate elements structures to be driven into the ground, and particularly piles, and structures thus obtained
IPC: A43B13/12
Filed: 1945-06-06
Abstract: 602,105. Piles. FREYSSINET, E. June 6, 1945, No. 14278. Convention date, July 19, 1944. Class 68(ii) Comprises several arrangements for building up piles and like structures from separate elements secured together under permanent stress. Each element is joined to those already assembled and is then stressed, the stress being maintained on all the parts then assembled whilst the next element is added and stressed and the pile driven farther and so on. The stress if derived from reinforcement members which may remain permanently in position but which are preferably removed on completion of the pile &c. The reinforcements are tensioned along the length of the separate elements as they are being assembled and are locked in the tensioned condition to the elements as the assembling proceeds. In the form shown, in Fig. 3, reinforcing wires 5 having spiral ends c are embedded in the bottom element 2 which may have a reinforced tip or may end in a ring 6. The wires may be tensioned by clamping to a ring 25, Fig. 12 supported by jacks 26 resting on the top of the element just assembled. The tensioned wires are locked to this element by a sleeve 18, 19 and staves 21, 23, the top of which may serve to receive the pile driving blows. The next element is then positioned and the tensioning and locking operations repeated. After the pile has been completed the reinforcements may be withdrawn by subjecting them to increased tension. In other forms, wedge means for temporarily securing the reinforcements in the bottom element, such as are described in Specifications 591,218, 592,430, 592,839, [all in Group X], and 2715/45 (as open to inspection under Sect. 91) may be used. The invention may be applied to screw piles made up of elements and also to piles wherein each element comprises several component parts with vertical joints between them. Specification 600,211, [Group X], also is referred to.

Title: Regulating the concentration of hydrochloric acid obtained by the process of adiabatic hydrogen chloride absorption
Inventor: KUNZER WERNER
IPC: C01B7/01
Filed: 1963-04-11
Abstract: In the manufacture of hydrochloric acid by the adiabatic absorption in water of a fluctuating supply of impure hydrogen chloride, the concentration of the effluent acid is maintained constant by controlling the water supply in response to said concentration whereby the temperature of the adsorption zone is sufficiently high to entrain impurities in the steam produced. Should the hydrogen chloride concentration decrease, the water supply is increased to form a dilute acid which is withdrawn, stored and fed instead of water in an ensuing period of high hydrogen chloride concentration in the feed gas.  The working temperature is preferably 80-100 DEG  C. As shown in Fig. 1, hydrogen chloride containing gas passes through pipe 1 into absorption packing 3.  When the amount of hydrogen chloride gas is insufficient for the working temperature to be reached, absorption water is supplied through pipe 4, controlled by valve 26, from tank 14.  The water level in tank 14 is kept constant. The hydrochloric acid formed passes through into <PICT:1032806/C1/1> pipe 7, where its electrical conductivity is measured by 8, overflows at 9, passes through gas seal 10, cooler 11, by-passing closed valve 23 and is stored in container 13.  When the rate of supply of hydrogen chloride gas is high enough for sufficient heat to be generated by absorption for enough water to evaporate to create a temperature of 80-100 DEG  C. at temperature sensing device 16, temperature regulator 27 firstly switches on concentration regulator 29 which now controls the amount of absorption liquid supplied to the absorption tower, secondly opens valve 23 so that pure acid flows into a reservoir (not shown), and thirdly causes contaminated hydrochloric acid to be pumped from tank 13 into tank 14 after a selected lapse of time, which closes valve 25 to stop the flow of water.  The level in the tank is controlled by overflow 20.  The contaminated hydrochloric acid is now supplied to the absorption tower, and when tank 14 is empty, valve 25 opens and water is again fed in.  If the supply rate of hydrogen chloride falls below a certain minimum determined by the flow of water and the size of the column, flow regulator 32 restores the control of the flow of water to remote control 21 and closes valve 23, whereby contaminated acid is again collected in container 13.

Title: A method and means for applying protective coverings to metal pipes
Inventor: ROWAN HAROLD CHARLES
IPC: B29C63/10
Filed: 1955-05-20
Abstract: 784,756. Covering pipes. WELLINGTON TUBE WORKS, Ltd. April 6, 1956 [May 20, - 1955], No. 14636/55. Classes 99(1) and 99(2). In a method of applying a protective covering to pipes c a succession of pipes interconnected by rupturable couplings are fed as a continuous pipe through an apparatus for applying the covering, and after emerging from the apparatus a lateral force is exerted on the leading pipe for rupturing the coupling between that pipe and the succeeding pipe and for severing that part of the covering which encloses the coupling. As shown in Fig. 1, a band a of hessian, felted or woven glass fibres, or slag wool is fed through a bath b of bitumen and then coiled helically on to the pipes, rotational and longitudinal movement being imparted to the pipes by power-driven rolls h having mutually inclined axes ; rolls i feed the pipes forward at a faster rate than the rolls h. Excess covering material is removed or smoothed by a scraper k and a coating of whitewash, sand, or paper m is applied to prevent adhesion of the coated pipes when bundled together ; when paper is used the pipes are sluiced with water by a sprayer o to cool and harden the coating. Upon emerging from the apparatus, the pipes are supported on rollers p, and a roller q exerts lateral pressure on successive pipes to deflect the forward pipe relatively to the following pipe to separate the successive couplings and simultaneously break the parts of the covering enclosing the couplings. The coupling members comprise sleeves d screwed on to the pipes and having interengaging spigots f and sockets e of polygonal or other non-circular shape and are such that rotary motion is transmitted from one pipe to another, but are disconnected by lateral deflection of one of the pipes relatively to the other of a pair of pipes. The sleeves d are covered with paper sleeves g coated with oil-bound distemper.

Filed: 1944-08-03
Abstract: 589,808. Roofs and floors. POLLAK, E., and HOFFMANN, A. J. Aug. 3, 1944, No. 14816. [Class 20 (iv)] Roofs and floors are formed by "trussless shells" consisting of transversely-arched units of small thickness and of a length which is a multiple of the width, the shells acting as beams and being without gables frames or trusses but being provided with means which prevent undue transverse deformation under load at one or at a number of spaced transverse sections. The shells may be moulded or made by bending sheet material, and may be, for example, of concrete, metal, resinous plastics, plywood, or asbestos. Fig. 6 shows a roof formed of trussless shells 1 supported on beams 3, ties 2 preventing deformation in transverse planes. In a modification, the shells are suspended from the beams 3, and in another they are inverted. The ties 2 may be replaced by struts 2a, Fig. 7b, between the shells, or may pass through a number of shells to form both ties and struts, Fig. 7d (not shown), in which case they may form also carrying beams. Fig. 8 shows a cantilever construction in which the shells are threaded through curved slots 7 in a wall, their curvature varying from a maximum at this section to zero at their outer edges. Circular roofs are similarly formed, Figs. 9 and 10 (not shown). The shells form gutters, leading the water towards the support. When the shell are moulded the ties or other means preventing transverse deformation may be adjusted to provide a degree of transverse prestressing. In the case of bent-sheet shells the shape is maintained by the ties &c.

Abstract: 151,063. Wilkinson, C. T. June 12, 1919. Suspending.-In order to minimize sagging of wires and strain on the masts due to temperature variations, snow, &c. in large aerial structures and to enable lighter wires to be used therein, the phosphor bronze or like wires c and supporting (" triatic '') steel cables 13 are passed over pulleys and counterbalanced by weights c', b<1>. The pulleys may be arranged in various ways - and the wires may be attached to a cable B at one end, as shown in Fig. 1, or otherwise. To reduce the bending moment on the mast, the pulley d' may be spaced back on an arm d' mounted pivotally or otherwise on the mast A, as shown in Fig. 2. A group of several wires c may be attached to a single wire carrying a weight, either before or after passing over the pulleys c<2>, springs being inserted in the individual wires; or a group of wires c may be formed by passing a single length of wire backwards and forwards between two lines of pulleys. Stops may be furnished to prevent creeping of the wires towards one end. To prevent the wires c from vibrating mechanically, independently of the vibrations of the masts, cross ties or frictional devices are provided; thus the wires c or pulleys e<2> may be tied together by transverse connexions, the pulley hangers being made specially long for this purpose, and, as shown in Fig. 11, the pulleys may be replaced by frames E<2> each containing two spring-controlled sliding pulleys e<4>, e<5>, or a third gravity- or spring-controlled pulley e<8>, Fig. 12, may be fitted in the frame E'. In order that the aerial may be lowered for inspection, the balance weights may be made hollow and filled with removable mercury or shot. Insulation is provided and the wires c may contain lengths of silk, rubber, or the like.. According to the Provisional Specification, the cables are designed to give way if the pulleys become jammed by frost, before the strain on the masts becomes excessive.
