A caster (or castor) is an undriven, single, double, or compound wheel that is designed to be mounted to the bottom of a larger object (the "vehicle") so as to enable that object to be easily moved. They are available in various sizes, and are commonly made of rubber, plastic, nylon, aluminum, or stainless steel.
Roll gap control method for double-roll cast rolling
The invention relates to the technical field of double-roller cast rolling, and provides a roller gap control method. According to the method, in the casting and rolling process, controlled floating of a roll gap is achieved under the condition of constant opening degree by controlling the overall movement of a driving device and a roll system and the relative movement between the driving device and the roll system, and therefore the material updating process in a molten pool is stabilized. Different from a traditional technical scheme, the method can keep the two roller bodies and the side sealing device static relative to the ground in the roller gap floating period, the thickness fluctuation of the green body is effectively avoided, the abrasion rate of the side sealing plate is reduced, and therefore the stability of the cast-rolling process and the quality of the green body are improved.

Car seat transport device
A Car Seat Transportation Device is an apparatus that holds and transports a car seat when it is out of a vehicle. The device takes the form of a cart supported by four (4) casters that rotate three-hundred-sixty degrees (360°) (spinner style), that easily roll over almost any surface. The rear of the device is provided with handle system, that adjusts in height, and is similar to that of a handle found on a stroller. The top of the platform, or base, that holds the removed car seat is adjustable, allowing use with almost any make or model of car seat. These features allow the device to safely hold a car seat with an infant or child inside of a home and also allow the car seat to function as a stroller as well. It also allows a parent or care giver to remove the car seat from a car with the infant or child still in place and place it on the device thus transforming it into a stroller without disturbing the child. It is great for travel, especially when moving between gates in an airport. Finally, when not in use, the device collapses, and folds for easy storage almost anywhere.

Spring Compression Casters and Jackstand Apparatus
A caster having a spring feature configured to compress along the stem of the caster when subject to load. The spring achieves maximum compression when subjected to a maximum specified load value. One or more casters may be used in tandem with a jackstand apparatus. When the jackstand is presented without any additional force, the combined spring force of all casters utilized is sufficient to support the weight of the jackstand without achieving maximum compression. When subject to a sufficiently large additional force, each of the springs will achieve maximum compression, and the jackstand apparatus will interact with the supporting terrain directly, resulting a direct transfer of additional load to the terrain through the jackstand apparatus. Some embodiments may comprise a distinct jackstand and cart configuration. Some embodiments may comprise an integrated configuration.
