It is forbidden to clean, lubricate the drum, chains, rollers, cleaning knives while the conveyor, auger is moving, eliminate belt slip by throwing rosin, sawdust, sand, etc. on the move.

27. When working on a centrifuge, you must:

when starting the centrifuge, first turn it on at low speed, while checking the operation of the device indicating the number of revolutions of the form, and adjust the correct installation of the form using jacks;
laying concrete in the mold at the command of the worker involved in the control of the centrifuge with the help of a concrete paver;
when installing the form on the belts of the centrifuge, be in a safe area, while approaching and correcting the form is allowed only from the end of the form, provided that the form is lowered at a distance from the base of the belts by 200 mm;
The centrifuge must only be operated with the end and top guards closed. Work with open end and top fences is prohibited;
at the end of the mold loading, the centrifuge speed should be increased smoothly. A table of form revolutions in the centrifuge should be posted at the workplace;

Otherwise, it is necessary to reduce the speed and adjust with the help of jacks.

28. When working on the tilter it is necessary:

slinging and uncoupling of slings from the mold on the tilter at the time of its being in a horizontal position should be carried out only with fixed stops;
make sure that the form with the product, installed on the tilter, is located with the socket towards the support platform, and the bandages of the form rest on the prism;

in case of a hose break or disconnection, it is necessary to turn off the pneumatic tool and close the valve on the air pipeline.

31. Slinging of products must be carried out for all available hook loops in products or forms, i.e. in accordance with the scheme of slinging of goods, posted on the working bridge of the moulder.

32. When moving the load, observe the distance that should be between protruding objects and the load being moved at least 0,5 m. Make sure that there are no people in the area of moving the load and on its way.

33. Laying molds at the formwork post and finished products in places designated for their storage should be carried out only on specially designed linings and gaskets in compliance with the clearance between the molds and products: at the demoulding post between the hinged sides of the molds - 1,5 m, in places storage of products - 1 m.

34. When laying products and shapes of circular cross section, linings and gaskets must be equipped with side reliable stops or shoes at the edges to prevent them from rolling out during storage and storage.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

1/4" 8 MP OmniVision OV8856 and OV88565 image sensors 14.09.2015

The resolution of mobile device cameras continues to increase. The main cameras confidently took the 10-megapixel mark, and the flagship smartphone models have twice the resolution. The front cameras, due to their supporting role, are somewhat behind, but their resolution is also increasing.

OmniVision analysts predict more than a billion units of 2017MP image sensors will be sold in 8 as the industry shifts to using front-facing sensors instead of the most common 5MP sensors today. In this case, the optical format 1/4 inch will remain unchanged.

Yesterday, OmniVision introduced two models of 1/4-inch 8MP image sensors for front cameras: OV8856 and OV88565. A distinctive feature of the OV88565 model is the support for phase focusing.

The new sensors use the proprietary PureCel architecture. The pixel size is 1,12 µm. The sensors allow you to shoot full resolution video at 30 fps and shoot Full HD video at 60 fps. In addition, support for high dynamic range (iHDR) should be noted. The sensors are equipped with four lines of the MIPI interface (two lines of MIPI are enough to display frames with a resolution of 8 megapixels without compression at a frequency of 30 fps). According to the manufacturer, OV8856 is one of the smallest 8MP sensors. It is 15% smaller than the similar OmniVision OV8858 of the previous generation. Using OV8856, it is possible to produce camera modules with dimensions of 6,5 x 6,5 x 4mm.

The OmniVision OV8856 and OV88565 image sensors are now available as evaluation samples. Serial production will begin in the fourth quarter of 2015.
