IPC: H02P3/24
Filed: 1981-10-17
Abstract: The invention relates to a method for the production of tows from melt-spun polyester filaments, which are drawn off their spinning points (3) at a predetermined drawing-off speed as filament bundles (4), are temporarily laid down, are heated in the course of further processing, are drawn/stretched to a predetermined residual extensibility, are heat-set, are subjected to a stretch-braking process in a tow-to-top converter and are finally crimped. The laid-down filament bundles (4) are heated in the tow-to-top converter to a predetermined temperature, without any intermediate treatment, are drawn/stretched to a predetermined residual extensibility, are heat-set and are subjected to the stretch-braking process. For this purpose, the tow-to-top converter has at least two tensioning devices (11a, 11b) in the filament bundle inlet region (10), and, thereafter, a stretch-braking zone (12, 15) and a crimping zone (13). A heating device (14) for the tensioned filament bundle (4) is arranged between the two tensioning devices (11a, 11b). The final tensioning device (11b) in the bundle movement direction is followed by at least one stretching device (16), forming a stretching zone (15). The stretching zone (15) has allocated to it a heating device (17) for heat-setting of the drawn/stretched filament bundle (4), at the same time forming a heat-setting zone. <IMAGE>

Title: Lifting appliance for producing masonry
Inventor: KROON JACOBUS CORNELIS ANTHONI
IPC: B66C23/20
Filed: 1982-06-15
Abstract: The lifting appliance is equipped with a jib (2) and a grab (3). A lifting rope (4) runs over an arranged pulley (5) to a driven rope drum (6). The drive of the rope drum (6) is provided with an adjustable magnetic slip clutch (9) which, by being loaded to a greater or lesser extent, sets the torque acting on the rope drum and can be changed over between a first state, in which at least part of the weight of the loaded grab is balanced, and a second state in which at most the weight of the empty grab is balanced. This ensures that the bricklayer can manipulate even a relatively heavy block and fix it in a wall to be produced as if it were only a brick of relatively low weight. He is merely relieved of the heavy physical work of lifting and displacing a heavy block. <IMAGE>

Title: Process for injection casting under vacuum of heat-curing epoxy resins and system for carrying out the process
Inventor: SUTER ALOIS ING GRAD
IPC: B29C45/34
Filed: 1982-07-15
Abstract: In a process for injection casting under vacuum of heat-curing epoxy resins, a vacuum chamber with adjustable working volume is used as the system. This vacuum chamber consists of three parts, a fixed frame part (1) and two mould mounting plates (2 and 3), which are inserted with piston rods (6 and 7) axially parallel into the frame part (1) and externally heated with heating plates (22 and 22a); two piston rods (6 and 7) are simultaneously used in order to press the casting mould halves (13 and 14) together and in order to centre an auxiliary frame (15) inserted in the parting plane of the casting mould halves (13 and 14). The casting mould halves (13 and 14) and the auxiliary frame (15) have a feed line (23), which is connected pressure-tight during the injection casting by the pressure-applying device (24) to the injection nozzle (11). For rapid venting of the cavity (25), the casting mould half (14) has a venting gap (18), a gas pocket (17) and a film vent (16). A flange (19) insulated with thermal insulating sheet (20) is mounted with bolts (26) in the fixed frame part (1). The injection of the epoxy resin into the cavity (25) is carried out by means of the injection nozzle (11), which is adjustable to the axis of the feed line (23) in the frame part (1) in a slit opening (21) by means of an actuating device (24). For sealing the vacuum chamber, the grooves (4a and 5a) are provided on the front side in the mould mounting plates (2 and 3). Two endless tubular seals (4 and 5) are inserted in these grooves in order to provide a seal against external atmospheric pressure. On account of the expansion and the subsequent pressure buildup of 4 bar of a gas flowing into the two filling line inclusions (8 and 9) installed in the mould mounting plates, a pressure-tight sealed vacuum chamber (27) is formed by the elastic deformation of the tubular seals (4 and 5) between the grooves (4a and 5a) and the inner surfaces of the fixed frame part (1), so that gas-bubble-free cast parts made of heat-curing epoxy resin can be manufactured in this system with a vacuum chamber that is protected against damaging gas inclusions in the cavity (25) of the casting mould halves (13 and 14).

Title: Method and feeding container to increase the sliding ability of pourable bulk material in the feeding container of a pneumatic conveying system
Inventor: TUTTNASS EDMOND ING
IPC: B65D88/72
Filed: 1982-09-07
Abstract: The sliding ability is increased by blowing a gaseous medium, preferably air, into the feeding container from outside. This is carried out to prevent caking and an ultimate danger of blockages in such a way that the air is blown into the feeding container, evenly distributed in areas at least, to form continuous layer zones and so a friction-reducing sliding layer is formed between the material being conveyed and the side of the container, which facilitates the trouble-free delivery of the material being conveyed from the metering chamber to the blast chamber and from there into the pipe under the pressure exerted by compressed air. <IMAGE>

Abstract: The mine support for underground use as well as for use in tunnelling consists of formed steel sections, preferably steel wire. The sectioning is provided in such a way that the coating thickness of the early-bearing mortar to be sprayed on is thus predetermined at the same time. The steel sections are connected via squeeze layers, the squeeze layers at the same time serving as spacers for the sectional wires. Serving as early-bearing compounds are, for example, thermal collite with filter ash, flue-gas desulphurised gypsum and cement. The steel wire is supplied in rollers to the face and is shaped and formed there and then directly attached and encased in mortar. A hydraulic device with a hydraulic arm serves to attach and simultaneously shape the steel wire. The arm carries a cylinder which produces the desired shaping and at the same time permits tight juxtaposition of the shaped steel wire and the rock. <IMAGE>
