This invention relates to a value controlled lead acid battery positive lead paste prolonging the working life of batteries and devices since it can avoid corrosion to the devices, harm to human bodies or non-uniform mixing which is composed of the components in following weigh percentage taking its weight as the primary standard: short fiber: 0.08-0.5%, water: 5-20% and lead powder for rest.

The invention relates to a drilling appliance (2), in particular a hand-held percussion drilling machine or a hand-held drilling hammer with electric drive motor. It is provided that the drilling appliance (2) has a sensor (24) for detecting the orientation of a drilling axis (B) and a sensor system (26, 28 fig 5) for detecting at least one drilling parameter, and also a device (52, fig 5) for evaluating output signals of the sensor (24) and the sensor system (26, 28) and for altering a movement of a drilling tool (10) of the drilling appliance (2) in response to the evaluation of the output signals. The drilling parameter may be rotational speed, torque, current supplied or power consumed.

An auto-injector comprising: - a body (1) receiving a reservoir (S), said reservoir (S) containing fluid product and comprising a piston (P), in the same way as a pre-filled syringe, - a piston rod (5) suitable for cooperating with the piston (P) of said reservoir (S), said piston rod (5) being movable by an injection spring (8) between a loaded position and an injection position in which said piston rod (5) has moved the piston (P) of the reservoir (S) in order to inject the fluid product into an injection site, - a visual, audio and / or tactile indicator device, for indicating to the user that he can remove said auto-injector from said injection site, said auto-injector comprising a delay system for delaying the actuation of said visual, audio and / or tactile indicator device relative to the end of the injection, said delay system comprising a reservoir (16) containing a fluid, a piston (19) being disposed in said reservoir (16), one of said reservoir (16) and said piston (19) being movable in translation in said body (1) when said delay system is actuated, and the other of said reservoir (16) and said piston (19) being fixed relative to said body (1) when said delay system is actuated, the translational movement of one relative to the other moving said fluid out of said reservoir (16), through at least one flow passage (161; 195), such that said translational movement is braked, said delay system comprising said reservoir (16) containing said fluid, said piston (19), a delay spring (18) attached to said piston (19) and to said body (1), a locking key (20) and said piston rod (5). Figure to be published: figure 1b

The invention provides a bridge-type mechanical arm for steel ladle lining refractory disassembly and an operating method thereof. A mechanical arm working body is hoisted onto an operating platform when operation is required and is fixed to the ladle opening center point of a vertical steel ladle, and multi-directional refractory disassembly of a steel ladle lining is achieved through working arm rotation and hydraulic hammer swinging. The bridge-type mechanical arm is simple in structure, convenient to maintain, and capable of achieving wired control operation, resisting high temperatures, greatly reducing occupational health hazards of employees and relieving the labor intensity of the employees. Moreover, the limitation that the temperature of the inside of the steel ladle is high and thus people cannot enter the steel ladle for manual disassembly is avoided, operating efficiency is improved, the tense turnover pressure of the steel ladle at the site can be lowered, and production requirements are guaranteed.
