Abstract: A structural form of expanded graphite which possesses a relatively high bulk density is obtained by treating a natural graphite with a mixture of nitric acid and sulfuric acid, washing the treated graphite by an aqueous solution containing magnesium ions, followed by a thermal treatment at a temperature of above 1200°C. A preferred aqueous solution to be used in said washing will contain magnesium sulfate, the resulted product having a pH in the range of 6.5 to 6.9. A preferred thermal treatment is in a flame resulted from a mixture of butane and oxygen. In this manner, the expanded graphite will be produced in-situ near the envisaged area for its use, being spread thereon by the combustion gases. The structural form of expanded graphite has the property to absorb relatively large amounts of liquid materials, such as petroleum products and strong mineral acids.

Abstract: A battery-driven electronic appliance comprises means for generating the threshold voltage value for selectively setting two (high and low) threshold voltage V H  or V L  depending on whether a specific load, for example, a motor (20) of a group of loads of a battery (15) is operating or not and a battery voltage monitor (21) for determining the advent of the replacing or recharging time of the battery depending on whether the output voltage V₀ of the battery is greater or smaller than the threshold value. Thus, it becomes possible to prevent mistaken determination resulting from the operation of the specific load which is great in power consumption to prevent the memory effect from occurring in, in particular, the secondary battery to enable its effective use until the lifetime of the battery is reached.

Abstract: An ink jet printing apparatus has a casing (1) which is divided into upper and lower regions by a dividing wall (60). In the lower region, between the dividing wall and the base of the casing is an ink circulation unit (19 to 25). A pump (25) of the of the ink circulation unit (19 to 25) passes ink from a main ink container (19) to a tube (39) and hence to a printing head (38) of the apparatus. The ink circulation unit (19 to 25) may have a filter (22) for filtering the ink before it passes to the printing head (38), and also have a secondary ink container (20) and a solvent container (21) for containing ink and solvent which are passed to the main container (19) as they are used up during printing. Access to the containers (19 to 25) and the filter (22), which need periodic replacement, is via an access cover (8) in the casing. The access cover (8) is at the front of the casing (1) so that it can be used by an operator when the printing apparatus is in its normal position. Above the dividing wall (60) is a circuit board unit (40,42,43) which controls the ink circulation unit (19 to 25), and also the printing head (38). The circuit board unit (40,42,43) is also close to a display panel (3) of the printing apparatus, and is separated from a power unit (48,54,57) by a vertical wall (41). Thus, since the circuit board unit (40,42,43) and the power unit (48, 54,57) are above the ink circulation unit (19 to 25), spillage of ink will not affect them.

Abstract: An apparatus for releasably clamping a substrate to a support platform, or other support means, at a face of the substrate is described. In one embodiment, a retractable clamp (30) holds a substrate (2) near its edges on a support platform (22) when the clamp is in its fully extended position. Oneor more leaf springs are mounted to the clamp and apply force to the substrate at respective points in the event the substrate adheres to the clamp, thereby releasing the substrate from the clamp. In a preferred embodiment of the present invention, one or more activators are positioned in cooperative relationship to the leaf springs to cause the leaf springs to retract into recesses in the clamp when the clamp is extended against the substrate. In their retracted position, the leaf springs do not contact the substrate so as to minimize the generation of particle contamination and the chance of the release leaf springs themselves adhering to the substrate.
