The presented invention relates to a method for writitng a pattern in a substrate and in particular to an improved method of forming a magnetic encoder scale by writing a pattern comprimising lines of different magnetic permeability in a stainless steel substrate.
F.32 International patent
COBISS.SI-ID: 12577819Provided is an apparatus for simulating the function of a human stomach and/or intestine. The apparatus comprises a flexible vessel, and a plurality of constriction mechanisms, wherein each of the constriction mechanisms is disposed annularly around the outer circumference of the vessel, and an inner diameter of each of the constriction mechanisms is variable such that the vessel can be locally and annularly constricted. The device is intended for the development of new pharmaceutical forms.
F.08 Development and manufacture of a prototype
COBISS.SI-ID: 1584732A parametric study of friction stir spot welding (FSSW) of lap joints in aluminium alloy 5754 using a pinless tool with scrolled shoulder is presented. Experimental plan was done according to the response surface methodology (RSM), where tool rotation speed varied between 988 and 3511 rev/min, plunge rate between 24.4 and 150 mm/min and dwell time between 1 and 3.5 s. The plunge depth was held constant at 0.4 mm. During welding, the axial force and torque were monitored using a dynamometer. The welds were tensile shear tested, and the broken samples were visually examined. The weld bond line and microstructure were analysed using light optic microscope under polarised light, and SEM was used for examination of fractured surface. Mathematical models describing the relationship between welding parameters and joint strength, axial force and torque were developed. FSSW parameters, at which maximal joint strength was obtained, were considered as optimal. At these welding parameters, the axial force and torque were in the lower range among tested parameters. Material flow and joint formation are experimentally presented and schematically illustrated.
F.04 Increase of the technological level
COBISS.SI-ID: 13806875The recent developments in Information and Communication Technologies enable remote monitoring and control of distributed work systems and, in turn, development of new products and services related to their operations and maintenance (O&M). The paper focuses on O&M of small hydropower plants (SHP) and assesses the feasibility of different levels of O&M automation. A model for O&M of SHPs is developed and used as a basis for an event-based simulation. A case analysis of 85 Slovenian SHPs is presented. The parameters of the model are determined based on publicly available data and data gathered through a survey amongst the SHP operators. The feasibility calculations are performed for three scenarios describing different levels of automation. The results show how the presented approach can assist in decision-making of individual SHP operators, O&M services providers, and policy makers.
F.24 Improvements to existing system-wide, normative and programme solutions, and methods
COBISS.SI-ID: 14265371Customers require short delivery times and lower price of products (lean production). These requirements of customers can only be met if a company switches from a classically organized to a lean production. This paper presents a value stream analysis that shows a size of the lead time (LTpp). Overall equipment effectiveness (OEE) and efficiency index (PE) allow us to determine a leanness index of a production process (LI). The value LI in fact show the leanness of a production process. Portfolio analyses of leanness of production process is shown on an example of production of cooling covers.
