Title: Improvements in or relating to pipe-bending machines
IPC: B21D7/022
Filed: 1953-08-31
Abstract: 759,036. Angular bending. BRINDLEY, F., and COCKS, G. Nov. 30, 1954 [Aug. 31, 1953], No. 23962/53. Class 83 (4). A pipe-bending machine, comprising a head on which is mounted a rotatable former to which the pipe is adapted to be clamped and around which it is bent, is characterized in that the head is mounted in a support for rotation about the axis of the pipe so that successive bends can be formed in the pipe in different planes and that means are provided for preventing angular movement of the unworked portion of the pipe about its axis during rotation of the head. A head 13, adjustable about its axis in bearings 12 in a pedestal 11 and counterbalanced by a weight 114, carries on a block 18 secured thereto, a peripherallygrooved backing roller 20 and an adjustable block 28 in which is pivoted a shaft 32 carrying a forming roller 33 having a peripheral groove 34 of twice the depth of the groove in the backing roller 20. In operation, a pipe P to be bent is arranged between a clamp jaw 45 on the forming roller 33 and an adjustable clamp jaw 40, on an arm 31 swingable about the shaft 32, and between the rollers 33 and 20 to pass through the head 13 and over a ballnosed mandrel 74 to be held by a collet 98, Fig. 6 (not shown), against rotation about the axis of the unformed part of the pipe. The collet 98 is adjusted along guides 81 to engage a first stop on a bar 85 parallel to the guides 81, to set the axial position of the pipe P for the first bend thereon. The head 13 is then adjusted about its axis and held in this position by brake shoes 110. To effect the actual bending the shaft 32 is rotated, by a handle 65. This causes eccentrics 50, Fig. 4, on the shaft 32, to move the arm 31 and thus the clamp jaw 40 toward the jaw 45 to clamp the tube to the forming roller 33 and then, when a dog 53 on the shaft end engages pins 54 upstanding from the arm 31, rotates the arm 31 and forming roller 33 about the axis of the shaft to bend the pipe around the roller 33. The pipe is then released from the clamp jaws 40, 45 and the mandrel 74 is moved back slightly in the pipe to unstick it by cam means, Fig. 5 (not shown). For further bending, the collet 98 is adjusted axially to abut the next stop on the bar 85 and the head 13 is suitably adjusted. A nest of superimposed forming rollers and a vertically adjustable vice jaw 40 may be used. The backing roller 20 may be replaced by a grooved slipper. The shaft 32 may be driven by fluid-pressure automatic return means.

Abstract: 771,098. Control of A.C. motors. SANDOZ, Ltd. Aug. 24, 1955 [Sept. 6, 1954], No. 24380/55. Class 38(3) A centrifuge is driven by an A.C. commutator motor having armature M and series field windings W1, W2, the motor being controlled by means of a manually - operated auto transformer R the adjusting arm of which is mechanically gauged with changeover switches U1, U2. The motor is started by setting the arm of the transformer in the range F, the motor continuing to operate until a time switch T opens at the end of a predetermined period so that the motor may be allowed to coast to a standstill. If, however, the transformer arm is moved beyond the zero position into the braking range B, the armature of the motor is reversed in relation to its field windings, the braking current being smoothly increased by further adjustment of the transformer in the same sense. The braking circuit is opened at a low predetermined speed by means of a centrifugal switch Z. In another arrangement, Fig. 2 (not shown), braking operation is provided by reversing the field winding W2 with respect to the armature M and field winding W1.

Title: Pressure control valve mechanisms
Inventor: BOCK RUDOLF
IPC: F15B11/20
Filed: 1969-05-14
Abstract: 1,272,278. Valves. R. BOCK. 14 May, 1969 [25 May, 1968], No. 24497/69. Heading F2V. A valve for sequentially connecting a plurality of devices to a common pressure pipe 38 and simultaneously connecting the unpressurized devices to a common exhaust chamber 28 has a plurality of slide valves in chambers 14-19, each of which valves is movable rapidly from a first control position in which it connects its associated device to the pressure pipe and the following device to exhaust to a second position in which the following valve is connected to the pressure pipe and its associated device is connected to exhaust. The sequence is initiated by a slide valve 13 that is movable from the Fig. 3 position in which the pressure pipe 38 is connected to a passage 30 leading to the common exhaust chamber 28 to a position in which the portion 131 cuts off this communication and portion 133 allows the passage of pressure fluid into the first slide valve chamber 14 via passage 37. The associated slide valve is in the upper control position (shown in Fig. 7) so that the pressure fluid flows via slide valve passages 50, 53, 51 into the passage 39 connected to the first device V1. Pressure builds up in the system to act on the differential piston portion 26 of the slide valve to move it downwards against a spring-loading (27). As soon as the pressure acts on the top concave area 58 of the slide valve it moves rapidly to its lower control position in which knife edge 61 engages seat 62. This movement opens a top passage 31 previously closed by a throttle portion 63 and knife edge closure 59 so that pressure fluid may flow into the next slide valve chamber 15. Simultaneously the communication of passage 45, which previously led to the following device via passage 51 in the following slide valve and passage 40, with exhaust via slide valve passage 56 is cut off. The associated device V1 is exhausted in the lower control position via passages 54, 55, The slide valves move from their upper to their lower positions in sequence to pressurize the devices until the last slide valve moves to its lower position when the pressure fluid acts underneath the slide valve 13 to move it to its initial upper position. Devices may be cut out of the sequence by moving the corresponding slide valve from the upper to the lower control position at the required time by a manually, electromagnetically or fluid-pressure operated rotatable eccentric acting on the portion 63 of the slide valve.

Title: Improvements in the manufacture and production of halogenamine alkylsulphuric estersor alkylsulphonic acids
Filed: 1934-08-27
Abstract: Compounds readily capable of splitting off halogen, and which are specially suitable as bleaching agents in the textile industry are prepared by the action of halogens on amines which contain directly attached to nitrogen at least one hydrogen atom and one alkylene group which bears a sulphur containing radical selected from the class of the sulphuric ester and sulphonic acid groups. The reaction is preferably carried out in the presence of a solvent not attacked by halogen such as glacial acetic acid, chloroform, carbon tetrachloride, or water, and with the addition of a basic substance such as calcium carbonate, zinc oxide or sodium acetate to absorb the liberated hydrogen halide.  If the reaction is carried out in the absence of solvents free from oxygen, acid-binding agents containing oxygen are to be employed. Excess of halogen is removed by the passage of an inert gas such as air or nitrogen.  The reaction is preferably carried out between 0--50 DEG  C.  Initial materials mentioned are the sulphuric esters of monoethanolamine, diethanolamine, propanolamine, butanolamine, butylethanolamine, propylbutanolamine cetylethanolamine, octodecylpropanolamine, cyclohexylpropanolamine, phenylethanolamine, tolylbutanolamine and naphthylpropanolamine; also the following true sulphonic acids:--aminoethanol sulphonic acid, N-methyl-, N-propyl-, N-butyl N-octyl-, and N-cetylaminoethane sulphonic acids, N-phenylaminopropane sulphonic acid, and N-naphthylaminobutane sulphonic acid.  In an example monoethanolamine sulphuric ester is treated with chlorine in glacial acetic acid in the presence of anhydrous sodium acetate at 40 DEG  C., excess of halogen removed by a stream of air and the precipitated product filtered.  The Specification as open to inspection under Sect. 91 comprises also, the treatment of aminoisopropanol sulphuric ester with chlorine in aqueous solution in the presence of calcium carbonate at 40--50 DEG C.  The excess of chalk is filtered, and the filtrate concentrated when the chlorinated aminoisopropanol sulphuric ester precipitates. This subject-matter does not appear in the Specification as accepted.
