Title: Bent tubular metal articles
IPC: B21D26/02
Filed: 1956-06-06
Abstract: 835,259. Making tube bends; expanding in dies; angular bending. FLEXONICS CORPORATION. June 6, 1956 [June 17, 1955], No. 17526/56. Classes 83 (2) and 83 (4). [Also in Group XXVIII] A method of producing fittings for tubing comprises bending a section of tubing, placing the bent tubing in a confining die and thereafter applying internal pressure to the bent section of tubing to stretch said tubing to a predetermined size and shape. A section of thin-walled stainless-steel tubing 22 bent to an included angle of 129 degrees is placed within a recess 34 in a lower half 24 of a forming die 26 and an upper half 28 of the die with a complementary recess 34 is placed and held on the lower half The die may be of steel or of plastic reinforced with glass fibres. A plug 46 is held in one end of the tube by a compressed rubber ring 60 and has a rectangular flange 50 anchored in recesses 36 in the die. A plug 68 similarly held in the other end of the tube and anchored in the die has a bore 82 therethrough communicating with a high-pressure hydraulic hose. Water under pressure introduced into the tube causes it to expand from the position 92, through a position 94, 96, at which it may be removed and annealed, to engage the walls of bulges 40, 42, 44 of the die recess 34, the cross-section of the tube at the bulges remaining circular, Fig. 3. The so-formed tube after annealing if desired may then be cut off along the planes 112, 114, Fig. 5, to form 90 degree elbow 116 to the ends of which flanges may be welded or brazed. In a modification, Fig. 8, a tube 128 bent to an included angle of 110 degrees is expanded in a die 130 through an intermediate position 150, 152, at which it may be removed and annealed, to engage bulges 154, 156 in the die recess. The so-formed tube, after annealing, if desired, is cut off along the planes 158, 160 to form the elbow 162, Fig. 9, having one arm of larger diameter than the other. A flange 164 may be attached to the large end. In another modification, Fig. 11, a bent tube 286, preferably after annealing, is expanded in a split die 274 to the form 296 and may be annealed after part expansion. The expanded form 296 is severed along planes 306, 308 to form a tapering bend of circular section.

Abstract: 380,803. Control of D.C. motors; drum controllers. BACQUEYRISSE, L., 53, Quai des Grands Augustines, Paris. June 18, 1931, No. 17730. Convention date, June 26, 1930. [Class 38 (iii).] Regenerative braking.-The series fields of compound-wound motors arranged for regenerative braking, are shunted from a point beyond the beginning of shunt field regulation during increase of speed, and down to a point past the end of shunt field regulation during reduction of speed. The controller for two traction motors shown in Fig. 2, has a loosely mounted contact segment 17 which is moved by the controller through a lost motion drive consisting of a pin 22 and stops 23<1>, 23<2>, and is effective to connect and disconnect a resistance 15 across the series fields 16<1>, 16<2> of the motors. The resistance 15 is connected at position V during increase of speed and remains connected up to full speed, and down to position III during decrease of speed, positions III to V forming the shunt field regulation range. In another arrangement described with reference to Fig. 1 (not shown), the resistance for shunting the series field of a single motor is cut in and out in two steps.

The leaf 31 may be planar or, as shown, predeflected before the elastomer 32 is bonded to it. The latter may taper in thickness (possibly from the centre), towards its ends and with a parabolic contour as shown. For attachment, the spring has bushings 44 in end lugs of an elastomer and a bushing 42 in the body 32, possibly at the centre as shown. As indicated in Fig. 5, a spring may be supported on a structure S at one end and between its ends to support a load P at its other end. Instead it may support a load at both ends being itself supported between its ends or, conversely, it may be supported at its ends to support the load between its ends.

Title: Process of producing poly-n-vinyl pyrrole compounds
IPC: C08F26/06
Filed: 1947-07-08
Abstract: N-Vinyl pyrrole compounds such as N-vinyl-pyrrole, -carbazole, -indole, -tetrahydrocarbazole, -propyl carbazole, -naphthocarbazole and N-vinyl-isopropyl carbazole are polymerised in the presence of liquid sulphur dioxide which acts as both solvent and catalyst. Other acidic catalysts such as sulphuric acid, boron trifluoride, tin tetrachloride, sulphurous acid and p-toluene sulphonic acid may be added.  Cooling may be effected by external use of liquid ethane, propane or ethylene or solid carbon dioxide.  Heat may also be dissipated by refluxing the sulphur dioxide.  A small amount of water may be added to initiate the reaction.  Polyvinyl carbazole so prepared may be dissolved in toluene and precipitated by methanol or acetone.

Abstract: 315,553. Hooks, W. J., and Long, A. S. June 22, 1928. No Patent granted (Sealing fee not paid). Ground anchors.-In a ground anchor in which the flukes c, c<1> are pivoted at e in the bottom of a tube a and are provided with extensions x, x<1> carrying pins k, k<1> which work in horizontal slots in a plate f movable in a vertical direction as described in Specification 298,426, means for locking the flukes either in the driving (vertical) or anchoring (horizontal) position comprise a thrust tube d rigidly secured to the striking head b and rotatably mounted in the tube a. A cushion s is interposed between the lower end of the thrust tube and the flukes and the meeting surfaces of the thrust tube and cushion comprise, teeth cr serrations j. A pin r on an extension g of the slotted plate f works in a cam slot h in the thrust tube. When the teeth of the thrust tube are bearing on those of its cushion the flukes are locked. A partial rotation of the striking head and thrust tube, limited by the shape of the cam slot h, causes the teeth of the thrust tube to register with the depressions in the cushion, thereby allowing vertical movement of the latter with consequent unlocking of the flukes. Relocking is effected by a further partial rotation of the head and thrust tube.

Abstract: 333,679. Stott, F. June 15, 1929, Selvedges, forming and protecting; warps, tensioning and guiding.-Selvedge distortion by the pull of the weft thread in weaving is prevented by passing the selvedge warps S between the coils of springs D on a rod A introduced into the warps. The selvedge warps are thus spread out and supported, and are given a varying tension bv the movement of the reed. The rod is made in two parts A, A', which are adjustably connected by a sleeve B and clamping nuts b, and at their outer ends are adjustably mounted additional sleeves C carrying springs D which are held in position by nuts C, C<1>. The selvedge threads, which are drawn through separate coils of the springs, are passed alternately above and below the sleeves C and thence through the healds K and the reed L. The additional tension, which is put on the selvedge threads while the shutter is passing through the shed, is removed at the beat up. Guides G, consisting of metal loops clamped to the back bearer H of the loom, prevent the warp threads controlled by the device from fouling the flanges J of the warp beam.

Annular ribs as at 67, 69 separate the body into separate switch compartments having one or more downwardly projecting conductors and other conductors as at 91, 92, 93 permanently immersed in the mercury and which may bridge between the separate compartments. An inert fluid such as oil or glycerine may be arranged to cover the mercury to prevent oxidation and cavitation. A current limiting circuit breaker arrangement comprises a ceramic bush 79 arranged in a dividing wall 74 between two compartments and having a narrow bore 79 below the level of the mercury and arranged so that excessive current vaporizes the mercury to break the connection. The switch is used for controlling the windscreen wiper motor of a motor vehicle and has three positions as determined by a spring-loaded ball 111 engaged in notches 107- 109 of the actuating member 62. The multiple contact circuit, Fig. 12 (not shown), is arranged so that the motor armature (114) and field coils (115) and (116) are selectively connected for low- or high-speed operation or for the parked position in which the rotation is reversed and the current directed via a limit switch (123) opened when the wiper element reaches the correct position.
