Title: Tyre conveyor for transport means
Inventor: MORITZHUBER JOHANNES
IPC: B61B12/06
Filed: 2018-10-09
Abstract: The invention relates to a tyre conveyor (1) for transport means, in particular cabins (5), of a cable car installation, comprising tyres (9), which are arranged along a track (8), and a drive train (14) for the tyres (9), of the at least one drive pulley (12), in particular a belt pulley, and at least one drive means (13), in particular a belt. A guide (16) is arranged along the track (8), at least in some sections, and at least one measurement device (17) for measuring at least one property of the drive train (14) or a component of the drive train (14) is displaceable on the guide (16). The disadvantage with conventional cableway systems, which are operated with a high demand for constant availability and at the same time with short downtimes for maintenance work, this also requires trained personnel to measure components on the drivetrain which in turn means that the cableway system needs to be shutdown. The sensors placed on the guides solves this issue and allows the constant monitoring of the drivetrain without having trained personnel carry out manual measurements and shutting down the cableway system.

Abstract: FIELD: equipment for loading of blasting means; cane be used for production of non-electric blasting systems for drilling and blasting operations. SUBSTANCE: the invention offers procedure and installation for application of explosive material onto the internal surface of shock-wave tube. The method consists in the fact that at manufacturing polymeric tube powdery explosive material is applied onto the internal surface of melted tube in its wide part at the outlet from the extruder; to this ends, a batcher is placed in this zone providing for forced mechanical introduction of explosive material particles in the tube melt. A centrifuge, pulsed atomizing source or a charging device furnished with an atomizer cone on whose surface explosive material is delivered to the melt and caught by the latter can be used as a batcher. The amount of substance delivered by batchers to the zone of application of coating is determined from condition of equality of surface density of explosive material of the tube wide and narrow parts. EFFECT: reduced consumption of explosive material as compared with manufacture of detonating cords, enhanced safety of drilling and blasting operations, prevented burn-out of initiated explosive material at bottom blasting (side effect).

Abstract: FIELD: space engineering. SUBSTANCE: both in space and on moon, components Hand Oare obtained through electric decomposition of HO from hydrate minerals. But taking into account mass of power source which is considerable even for small sources of 300 kW, components Hand Oare obtained thermally. Powder of helium oxides is fed in thin layer to asbestos tape moving in furnace and is heated by focused sun rays at 2000 C at low pressure for complete reduction of ferrum. Then finely crushed water steam is passed through ferrum at 500 to 700 C obtaining Hin water steam in amount of 40 to 50 percent. Then Hand Oare liquefied in space cold and tanks of rocket stages are filled with these components. Ferrum, cobalt, chromium as well as Hand Oare obtained similarly by thermal method at 0.1 atm under ground conditions. In case of difficulty to obtain hydrates in space or on moon, as well as in case of small amount of hydrates, use may be made of silicon and aluminium. SiOmixed with carbon is fed to tungsten tape and sun rays are focused on tape from below. Provision is made for additional re-reflecting mirrors to reduce losses due to reflection of rays from tape owing to which reduced silicon may be heated to 2500 C, after which it is poured into rocket tank, thus reducing demand of Hto 15 percent at outlet velocity of rocket nozzle increased to 5.5 km/s. Carbon is reduced from CO by electric decomposition at 200 C is space cold; recovery of carbon may effected chemically with hydrogen or ferrum at obtaining O. EFFECT: enhanced efficiency.
