A greasing mechanism for a main electric motor of a vehicle includes a greasing tube that is filled with a semi-solid lubricant and has an indicator member within the greasing tube. The indicator member has a specific gravity that is smaller than that of the semi-solid lubricant and moves in a greasing direction from a first position due to pressure of the semi-solid lubricant during greasing. The greasing mechanism includes a retaining part that has a shape that stops at a second position the indicator member moving during greasing. An indicator window arranged in a portion of the greasing tube including the second position is formed from a component that is at least partially transparent to visible light.

An oil tank includes an outer wall with a side limitation and an interior enclosed by the outer wall. A view passage extending from the side limitation into the interior of the tank allows external visual reading of the oil fill level of the tank at or close to the tank center, where changes in the oil fill level caused by inclined positions of the tank are minimal. The view passage includes a beginning of the passage formed in the area of the side limitation that includes a first optically transparent window. An end of the passage includes a second optically transparent window. A passage wall extending between the beginning and end of the passage delimits the view passage against the interior of the tank.

The invention relates to a fire extinguisher with a checking function comprises a fire extinguisher body; a through hole is formed in an upper part of a side surface of the fire extinguisher body; a fixing seat is mounted at the through hole; a checking component is arranged inside the fixing seat; a cavity is machined inside the fixing seat; a groove is formed at a front end of the cavity; a rubber ring for fixing the checking component is mounted inside the groove; a cambered surface mated with the checking component is machined inside the fixing seat; and the checking component is a transparent glass bead. The fire extinguisher has the benefits that the fixing seat is mounted on the fire extinguisher body, a fixing sleeve is mounted on the fixing seat, the glass bead is mounted at the internal cavity of the fixing seat and the fixing sleeve, the through hole is formed in the fire extinguisher body and the fixing seat is fixedly welded on the through hole; thus the fire extinguisher has many advantages that the structure is simple, fire extinguishing agents inside the fire extinguisher can be checked or liquid level and liquid weight can be inspected remotely (transmission of photos and of the latest identification code over a network), an warning about insufficient liquid amount is sent out using a travel controller, and it is convenient and efficient to use the fire extinguisher.

A container to hold contents therein is described with a gauge to indicate the level of contents in the container. The container can be a prescription container to store capsules, tablets, pills and the like. A label is affixed outside the container and is substantially opaque such that the interior is not visible through the label. The label including a vertical, transparent viewing window to see past the label, through the container wall to view the contents therein. The label includes indicia and indicators adjacent the window to indicate a time remaining for the supply of contents in the container or other characteristics of the contents. The time remaining can be calculated by the container volume and characteristics of the contents.

A liquid sensor includes a light receiver configured to receive light. The light receiver is attachable to an outside of an accommodation unit into which a liquid is introduced and which has translucency. The light receiver receives light that has passed through the liquid in the accommodation unit or light reflected by the liquid, and outputs a signal related to a physical quantity of the liquid.

The present invention disclosed a system for generating and supplying hydrogen gas to an internal combustion engine. The system comprises at least one hydrogen generator unit configured to generate hydrogen gas from water received from a primary water tank connected to the hydrogen generating unit. The hydrogen generating unit is also connected to an electrical control unit of the hydrogen generator unit which controls supply of power from a power supply unit for the electrolysis of water at the hydrogen generating unit. The hydrogen generating unit also connected to a car electrical control unit whereby through the operation of the electrical control unit of the hydrogen generating unit connected to the car electrical control Unit it enables the system to control activation/deactivation of the hydrogen generating unit, the output rate of the hydrogen to be generated, the quantity of the hydrogen to be supplied to the engine system through a back fire prevention unit disposed between the primary water tank and the engine system.

The claimed invention relates to bottles used by exercise enthusiasts for carrying liquids, solids and/or powdered nutritional supplements with liquids for mixing said supplements. Exercise aficionados consume a variety of hydrating liquids, nutritional supplements mixed with liquids or solid food items before, during and after their exercise periods. People who exercise use a variety of bottles including shakers, squeeze and water bottles to hold and consume their liquids, foods and supplements during their workouts. The present invention is an improved dual compartment shaker bottle for various nutritional supplements, liquids and combinations thereof. The dual compartments allow the user to carry two different liquids, nutritional supplements, combinations of liquids and supplements or solids for use before, during and after their workout. They no longer need two or more shaker bottles to accomplish this. Further, the claimed invention includes two compartment tops that securely attach to the bottle with a screw on and off mechanism and provide openings to consume the contents of each chamber. Each chamber is designed with curved closed end without corners/angles that cause clumping and reduced dissolving of supplements. The disclosed invention has attachment clips at each end to assist the user in carrying the bottle in a number of places. Further, the side of the bottle is ribbed for easy gripping. To assist the user in assessing the volume of material in each compartment, a measuring scale is included along the length of each compartment. A double wall exterior is disclosed to provide insulation to maintain the temperature of the materials in each compartment.
