Summarize the following:
when you can. Of course, no one can avoid every fall. However, you can try to be more careful, since falls are a common cause of shoulder dislocations. Pay attention when you're walking, so you notice anything in your path. Also, make sure to wear stable shoes, so you don't lose your balance as easily. If you do fall, don't try to break your fall with your hand or elbow, which can dislocate your shoulder. Keep your wrists and elbows bent, and try to twist so you land on your side or buttocks, avoiding your back. One of the main causes of shoulder dislocations is traumatic injury. These types of injuries often happen in sports, so wearing protective gear, particularly on and near your shoulders, can help protect you against a shoulder dislocation. When putting on your gear, make sure that it fits you correctly, and that you are putting it on properly. If you don't know how, ask someone, or do a quick internet search to find out more. When you're playing a sport where you use your shoulder often, stay off the field when your shoulder is out of commission. If you can't use your shoulder properly, you risk injuring other parts of your body, whether you're tackling in rugby or football, checking in hockey, or throwing in basketball or baseball. For instance, the new method of tackling in football requires you to keep your head up to reduce the possibility of concussions. That means your shoulder takes the brunt of the hit. Keeping your head safe is more important, so don't play when you can't use your shoulders.

summary: Avoid falls Wear protective shoulder pads and other protective gear for sports. Stay out of the game until you can use your shoulder properly.

The best way to use an ice cream machine is to follow the instructions that came with the model of machine you purchased. If you do not have the instructions, you can likely find time on the manufacturer's website. However, the description below should fit most ice cream makers. Many ice cream makers come with a bowl that should be frozen completely (usually for 24-hours) prior to making ice cream. Sometimes the bowl has liquid between the inner and outer walls of the bowl that freezes to help keep the product cold. Old-fashioned ice cream makers that do not have a frozen bowl may have a stainless steel (or other metal) bowl that sits inside a bucket of ice and rock salt. The salt helps melt the ice, which makes for a colder environment around the outside of the bowl. Most ice cream machines have a detachable paddle that stirs the mixture inside. Put the paddle in place per the manufacturer's instructions. Remove the sorbet mixture from your refrigerator (where it has been cooling) and carefully pour it into the ice cream maker bowl. The ice cream maker should do most (if not all) of the work for you. Turn it on and it will spin for a set amount of time or until the mixture is frozen. Some models have a timer on them for a pre-determined length of mixing time, while others will automatically shut off once they meet a certain amount of resistance (caused by the frozen mixture). Depending on your machine, your sorbet may be very soft when it finishes mixing. If this is the case, you may want to place the sorbet in an air-tight container and put it in your freezer to harden.

summary: Consult your machine's manual. Freeze the bowl. Place the bowl into the machine and add the paddle or stirrer. Pour the sorbet mixture in the bowl. Turn the machine on. Re-freeze the mixture for a firmer texture.

The hoses from your torch should attach to the nozzles on the oxygen and acetylene tanks. Typically, oxygen tanks and hoses are green, and acetylene hoses are red. The hoses are usually paired together, and the ends are separated so they can attach to their respective tanks. The acetylene hose will have reversed threads and a male fitting to make it easier to tell them apart. Since the fittings are made of brass and can easily be damaged, tighten them with an appropriately-sized wrench. To check that the regulator is completely off, back the tee handle out a few turns. This handle will be on top of the tank right next to the regulator valve. This will help ensure that you have complete control over the acetylene gas pressure. At higher than 15psi (100kPa), acetylene becomes unstable and may spontaneously ignite or explode. Again, it's extremely important to maintain control over the flow of the acetylene, so you want to open the gas valve just enough to allow a constant, steady flow of the gas. Opening the tank more than a single turn could lead the gas to become unstable, and it will be harder to turn off in the case of an emergency. This is the same handle that you closed before opening the gas valve. You should open this very slowly, and you should constantly monitor the low-pressure gauge while you're opening the valve. Open it only until the pressure indicated is between 58psi (3455kPa). To vent the atmosphere from the acetylene hose, open the gas valve on the cutting torch handle until you hear gas escaping, then observe the low-pressure gauge to see if the pressure remains steady during flow and ensure that you have this regulator set correctly. Close the acetylene valve on the torch once you are sure the pressure is regulated.. In the same way that you closed the acetylene regulator, back the oxygen regulator gauge out a few turns. Once you've done that, turn the handle on the main oxygen tank so it's all the way open. The setup on top of the oxygen tank will be similar to that on the acetylene tank. The oxygen valve is a double-seated valve. When you open it, be sure to turn the handle so the valve is all the way open. Otherwise, the oxygen will leak out around the valve-stem O-ring. Just like with the acetylene regulator, you'll turn the tee handle very slowly, watching the low-pressure gauge as you do so until the pressure reads between 2540psi (170280kPa). There are 2 valves on the oxygen side of the cutting torch assembly. To begin with, open the valve closest to the hose several turns to ensure sufficient oxygen is available for both functions. Next, open the forward valve slightly until the hose is purged (about 3-5 seconds for a 25 feet (7.6m) hose), then close the forward valve. The valve near the hose connections will control the flow of oxygen to the mixing chamber for the combustion, so no oxygen should vent from the torch tip until either the cutting lever is depressed or the valve further up the torch is opened.
summary: Hook up the gauges to the appropriate tanks. Make sure the acetylene regulator is turned off. Open the gas valve on top of the acetylene tank with one turn of the wrist. Open the regulator valve by turning the tee handle clockwise. Open the gas valve on the torch handle to vent it. Turn the oxygen regulator off, then open the main oxygen tank all the way. Open the oxygen regulator valve slowly. Open and close the oxygen valve on the torch to vent the atmosphere.
