All car owners, without exception, sooner or later have to repair their vehicles. Well, of course, if you have to do it "planned", but nevertheless you need to be prepared for all sorts of surprises and be fully armed. Therefore, it is necessary to have at your disposal the maximum number of required tools. In most cases, the basis of such a set is a set of socket wrenches manufactured by various domestic and foreign manufacturers. The proposed device will be able to complement this kit, as well as speed up the repair procedure.

The device is a flat handle with a rotating shaft. On the one hand, an eyelet is made on the shaft for connection with a folding handle, and on the other hand, a square section ending corresponding to the mating dimensions on the interchangeable head of the socket wrench. In principle, this place should completely repeat the same on the standard handle from the set, and therefore, depending on the keys you have, you need to clarify its dimensions. If desired, a spring and a ball can be inserted into the side face of the square, which protects the head from falling out while working in a hard-to-reach place.

Additional handle for a set of socket wrenches (click to enlarge): 1 - shaft (steel, bar d22, L38); 2 - folding handle (steel, bar d16, L100); 3 - handle (steel, strip 30x10, L220); 4 - retainer (M5 screw); 5 - spring (steel, d3,5, L15); 6 - ball, d3,5); 7 - handle axis (steel, bar d4, L22)

Using the key is very simple, and in many ways more convenient than a standard handle. The difference lies in the fact that, when unscrewing or tightening a bolt or nut, it is not necessary to throw the handle: you can work by constantly rotating the folding handle. When tightening or loosening difficult fasteners, force can be applied through the handle lever by lowering the folding handle to the bottom position until it stops.

In the manufacture of an additional handle, a wide range of materials can be used: for example, steel St3 or steel 45.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Huawei Ascend D quad Quad-core Smartphone 01.03.2012

Huawei unveiled its flagship smartphone Ascend D quad at Mobile World Congress 2012. Both new products have two things in common: both are built on the proprietary K3V2 single-chip system and are controlled by the Android 4.0 Ice Cream Sandwich operating system.

Huawei K3V2, as you know, can operate at a frequency of 1,2 or 1,5 GHz, in the case of Ascend D quad, the second, most productive option is chosen. The smartphone is equipped with a 4,5-inch touchscreen display with a resolution of 1280 x 720 pixels (pixel density is approximately the same as that of the iPhone 4S), made using IPS technology, an 8-megapixel main camera with a back-illuminated image sensor, and a rechargeable battery with a capacity of 1800 mAh According to the creators, depending on the operating mode, the smartphone is able to work from one to two days on a single charge. Extend the "life" of the battery allows proprietary power management technology, providing 30% energy savings.

The amount of RAM device - 1 GB, integrated flash memory - 8 GB. Given that the latter is not as much as we would like, the developers endowed the smartphone with a microSD slot, which accepts media up to 32 GB. In terms of communications Ascend D quad is not deprived: the device supports wireless data transmission technologies HSDPA (up to 21 Mbps), Wi-Fi 802.11b/g/n, LTE and Bluetooth 3.0. In addition, Huawei Ascend D quad has a gyroscope, an accelerometer, a proximity sensor and a digital compass, a 1,3 MP front camera, a GPS receiver, a microUSB port, and support for Dolby Mobile 3.0 Plus technology.

Dimensions smartphone - 129 x 64 x 8,9 mm, weight - 130 grams.
