The method involves defining a target geometry of a helical spring by a numerically controlled (NC) control program, and measuring an actual position of a structural element of the spring relative to a reference element at a measuring time point. The actual position is compared with a target position of the structural element at the time point for determining actual position difference that represents difference between the actual position and the target position at the time point. A position of a pitch tool (130) of a shaping device (120) is controlled based on the position difference. Independent claims are also included for the following: (1) a computer numerical controlled spring winding machine comprising a feeding device for supplying a wire to a shaping device (2) a computer program product for executing a method for manufacturing a helical spring.

The invention specifically discloses a medical insole with an effect of preventing and treating chilblain and a preparation method of the medical insole. The medical insole is characterized by comprising a surface layer, a middle layer and a bottom layer, wherein a medical mixture is coated on one or two faces of the middle and bottom layers, and the medical mixture is a liquid prepared by mixing the following components in percentage by weight: 3-5% of camphor, 5-7% of boric acid, 6-8% of menthol, 1-2% of tannic acid, 0.25-0.75% of thymol crystals, 0.5-1.5% of vitamin E, 0.25-0.5% of niacin, 4-6% of a salvia extract, 6-12% of tween 80 and 68-74% of purified water. The preparation method comprises the following steps: taking 70-90% of the liquid; adding 10-30% of an adhesive to mix and heat to paste; then, uniformly brushing the liquid any one or two faces between the middle layer and the surface layer; then, adhering the surface layer, the middle layer and the bottom layer; and drying and sewing to obtain the insole. The preparation method disclosed by the invention is simple and suitable for popularization and application, and has a very remarkable effect for chilblain and rahagades of feet.

The present invention relates to a gas generating agent composition for reducing combustion temperature and maintaining morphology, a preparation method therefor, an application thereof and a gas generator, the gas generating agent composition comprising the following components in mass percentage: guanidine nitrate 10%-40%; basic copper nitrate 30%-50%; amidinoureacopper nitrate 10%-50%; ammonium perchlorate 1%-10%; aluminum hydroxide 1%-10%; and talc powder 0.1%-10%; the gas generating agent composition uses the amidinoureacopper nitrate as a cooling agent and auxiliary fuel of a formulation to reduce the combustion temperature of the formulation without lowering the combustion rate of the formulation, and provides a sufficient oxygen source for the formulation; in addition, the agent improves the slagging capabilities of the gas generating agent after combustion by means of using large particles of aluminum hydroxide as a slag forming agent; in addition, by means of using ammonium perchlorate as an ignition performance modifier, the low-temperature ignition performance of the composition is significantly improved while the combustion rate is increased. The gas generating agent composition is mainly used in a gas generator of a car airbag.
