Draft block for dough processing
Novotný, Jan ; Vlašic, František (referee) ; Dvořáček, Jiří (advisor)
The Bachelor´s thesis deals with a structural design of a draft block of the placement of dough processing rollers, which are used for stiffening wheat dough in bakery lines intended for the production of common bakery products. The introduction gives a description of a bread and common bakery making production line. Next the thesis briefly deals with other possible dough-stiffening methods and with sanitary, structural and material requirements for food processing machinery. The structural part is devoted to a roller propulsion draft and a solution of a shift of one of the rollers. It contains a calculation of a worm gear, a load shaft calculation and a complete design documentary materials.

Desk for splitting semiautomatic
Jurák, Pavel ; Vlašic, František (referee) ; Dvořáček, Jiří (advisor)
The subject of the bachelor thesis is the design of the working table, which will ensure the stem lifting and its transport to the splitting semi-automat. Lifting of stem with weight up to 500 kg is ensured by lifting arms. Then, the stem is moved to the splitting semi-automatic by means of a belt conveyor. The design of the frame is designed to withstand a load of 5000 N. The lowest security has k = 1.2 according to the strength analysis. The table frame can be easily folded using a hydraulic cylinder. Thanks to this we can easily mount the frame behind a splitter semi-automatic and transport both devices at the same time.

Scanning of acoustic emission signal by using waveguides
Bančák, Matej ; Vlašic, František (referee) ; Mazal, Pavel (advisor)
Bachelor thesis is focused on the issue of scanning acoustic emissions from the surface of solid body and scanning with the help of acoustic waveguide placed on the solid body. The work includes the review of the present ways of scanning acoustic emissions, options of installation waveguide and propagation of waves. The practical part is focused on the experiment, which compares measured values from the surface of the test body and from the waveguide. The measurement was realized on steel of the standard quality for using a measuring instrument Dakel Xedo. The next object of this work was try to attenuate the reflected signal, which is produced by the action of force on the test body.

Problem Solution of the Control Mechanism of the High Voltage Disconnector
Metelka, Jiří ; Dvořáček, Jiří (referee) ; Vlašic, František (advisor)
This Bachelor‘s thesis deals mainly with the design of a safety ball clutch for the control mechanism of a high voltage disconnector made by IVEP company. This work includes a short summary about disconnectors and safety couplings in general, with concrete examples of disconnectors by IVEP and construction examples of commercially used safety clutches from number of randomly selected producers. The thesis also contains component drawings, assembly drawing and a 3D model of the complete coupling. Attached are the control measurement results of the torque moment of the completed prototype.
