Title: A new and improved method of and means for curling and waving hair and similar fibres
IPC: A45D2/34
Filed: 1944-10-03
Abstract: 634,074 Hair-curling appliances SARTORY, P. Oct. 3, 1944,No. 18879. [Class 131] In a method of permanently waving hair a tress is wound under tension on a mandrel, placed in an envelope or holder and the mandrel rotated to partly uncoil the hair before subsequent treatment. As shown, the hair 1 is wound in croquinole fashion on a mandrel 5 adjustably supported in spring clips 4 mounted on the end brackets 3, 3a of a clamp 2. A perforated, tubular and longitudinally hinged envelope 6 is secured round the tress by the spring clip 10 and the mandrel, which may be subsequently removed, rotated to relax the tension before the hair is treated by an autogenous heating pad or electric heaters in lateral extensions of the envelope. In modifications the envelope 6 may be dispensed with the spring clip 10 and the end brackets of the clamp forming a holder to confine the hair when the tension is relaxed. The envelope may incorporate, on its inner surface, chemical treating elements and the mandrel may be perforated for the introduction of treating materials. In a further modification the envelope may be an open-ended tube into which the coiled tress is inserted endwise. The Provisional Specification describes the application of the method to spiral winding processes.

Title: Improvements in corrugating apparatus
IPC: B21D15/06
Filed: 1954-06-29
Abstract: 759,099. Corrugating. ZALLEA, J. P. June 29, 1954, No. 19048/54. Class 83 (4). A method of corrugating a pipe section includes applying axial pressure to the pipe while applying axially spaced radial pressures on opposite sides of the pipe wall around the pipe circumference, the pipe being supported with its central longitudinal axis vertical and being rotated therearound. A cylindrical shell 157, to be corrugated, having external flanges 159 at each end is supported and rotated with its axis vertical, between outer roll elements 54 and inner roll elements 72, by freely rotatable wheels 161 engaging the inner surface of the shell and wheels 163, which may be rotated through shafts 168 from a main drive shaft 177 driven by a motor 191, engaging the lower flange 159. The outer roll elements 54 are keyed on a vertical shaft 46 rotated on a fixed axis by a worm 184 on the drive shaft 177. The inner roll elements 72 are keyed on a vertical shaft 64 journalled in an upper slide 63 and a lower slide 69 and rotated by a worm 183 keyed on the drive shaft 177. Cam elements 88, slidable on two vertical shafts 87 rigidly carried by a lower slide 84 and an upper slide 82, engage in staggered relationship the outer roll elements 54. Cam elements 99, slidable on two vertical shafts 98 rigidly carried by a lower slide 96 and an upper slide 93, similarly engage the inner roll elements 72. The outer cam slides 82, 84 are connected by tie rods 102, 103 to the inner roll slides 63, 69, while the inner cam slides 93, 96 are normally fixed, but are unlatched by toggle means actuated by the slides 63, 69 towards the end of their movement outwards so that towards the end of the inward or return movement of the slides 63, 69 they may push the slides 93, 96 to an innermost position suitable for preparing the machine to receive the next shell to be corrugated. In operation the inner roll slides 63, 69 are moved outwards, by screws 132 driven from a motor 153, in predetermined steps so that the inner roll elements 72 engage the shell 157 and in co-operation with the outer roll elements 54 corrugate it, the steps being so timed that they commence at a different point on the shell circumference each time. As the slides 63, 69 continue to move outwards the outer cam elements 88 are moved from the outer roll elements 54 and the inner roll elements 72 move from the inner cam elements 99, the roll elements thus closing up on axially their shafts. At the same time a fluid pressure cylinder means 129 lightly presses a sleeve 56 axially on the shaft 46 and then, as the roll elements disengage the cam elements, presses the sleeve 56 more heavily to push on the upper flange 159 of the shell 157 to compress the shell axially, another fluid pressure means 129 holding a collar 74 on the other roll shaft 64. The inner roll slides 63, 69 are then quickly withdrawn inwardly and the machine re-set. The shell supporting wheels 161, 163 may be adjustable for differing size of shell. The wheels 163 need not be driven, the shell being rotated by the roll elements.

Convention date, July 9, 1931. [Class 38 (v).] A gas-discharge relay with cold electrodes for over-potential or contact protection comprises a main discharge path and an auxiliary discharge path of lower ignition potential which is controlled by auxiliary controlling potentials, the two paths being coupled together by means of controlling electrodes conductively connected together and arranged in the discharge gaps or by means of a common control electrode disposed in both discharge gaps, so that when the auxiliary discharge occurs the controlling electrode of the main discharge path assumes substantially the potential of one ofthe electrodes of the main discharge path. In one embodiment, the main discharge path is between the electrodes 2, 3 with an ignition voltage of, say, 300 volts, and the auxiliary path is between electrodes 5, 6 arranged closer together in the same envelope 1 and having an ignition voltage of, say, 80 volts. Electrodes 3, 6 are connected together and a control electrode 4 extends into both discharge paths. As shown, the main discharge path is bridged across an " outer " conductor 12 and a neutral conductor 13 and includes a relay 14, the auxiliary discharge path being connected between the neutral wire 13 and earth 11 or some body that should not exceed a certain potential relative to the neutral wire. If the difference of potential between electrodes 5, 6 exceeds the ignition voltage, the auxiliary discharge occurs, electrode 4 assumes substantially the same potential as electrodes 6, 3, and the main discharge is initiated. This may switch off the network either by operating the ordinary overload cut-out or by operating relay 14 to control a no-volt release. The main discharge path in addition acts as an over-potential protecting device. The device may comprise two discharge tubes, Fig. 3 (not shown), a limiting resistance being connected between the control electrodes of the tubes.
