Abstract: A device for checking the printing circuit of a thermal printer wherein pulse currents are passed through only those of the heaters which correspond to printing data stored in a shift register via a power supply resistor and driver transistors to energize the corresponding heaters so as to effect color printing for one operation on heat-sensitive pater. The device comprises a self-examination control section for effecting at least one of the three types of checking, i.e., a check on the driver transistors for malfunction, a check on the heaters for malfunction, and a check on the shift register for malfunction, the arrangement being such that the printing circuit is automatically checked without actual printing operation by making use of the waiting time in which the thermal printer is not printing. 
     Checking the printing circuit by the present device avoids delay in printing and dispenses with manual operation for checking. Thus, it increases the reliability of the thermal printer and avoids wasting heat-sensitive paper and heat-sensitive labels for checking.

Abstract: An improved process for etching the inner surface of a glass capillary column in which ammonium bifluoride in liquid methanol is passed slowly through the capillary bore for a period of time followed by rinsing with methanol, followed by a gradually diluiting rinse mixture of methanol and water, and finally by a pure water rinse. A very fine structured etch of uniform depth is produced with no apparent air entrainment making the column suitable for all standard stationary phase coating procedures. Improved deactivation of the inner surface of the capillary column prior to coating with stationary phase is obtained by a multi-step process whereby siloxane polymer molecu les are chemically bonded to the capillary inner surface. The deactivated surface is adapted to coating with an apolar liquid stationary phase.

Abstract: The sealed feed-through (1) interconnects two cells of an alkaline storage battery (eg. for an electrically propelled car) by passing through a wall (2) of the battery. The battery includes a monobloc casing of plastic material defining at least two battery cell compartments which are separated by said wall, and said wall has an orifice for receiving the feed-through. The feed-through comprises a first portion (10) for electrical connection to electrodes (7) of a first polarity in a first one of the cells and a second portion (20) for electrical connection to electrodes (7') of opposite polarity in the other cell. In an alkaline battery, conventional welding techniques for making such feed-throughs in lead-acid batteries are not applicable because metals such as nickel steel must be used instead of lead. The resulting welding temperature would destroy the plastic wall. Instead, the first and second portions include interfitting male and female portions (11 and 21) suitable for passing through said orifice from opposite sides thereof and for engaging each other in a force fit. Respective skirts surround said interfitting portions and serve to compress at least one deformable sealing member (30) around the orifice. Stops are provided to prevent the wall being crushed when the feed-through portions are forced together.
