A retractable battery tray includes a supporting structure, a tray assembly, and a heating device. The support structure of the battery tray generally spans and attaches to two spaced apart supporting base structures of a telecommunications equipment cabinet and supports the tray assembly therebetween. one or more batteries are supported and carried on a tray member of the tray assembly and vertic...

A device for applying transverse welds and transverse severing cuts or transverse severing seams to an intermittently advanced tubular or semi-tubular web made of a thermoplastic material and for stacking the cut-off sections, comprises a transverse welding and transverse cutting station (2) for cutting sections from the web which are provided with floor welds and, if appropriate, additionally wit...

An apparatus for the provision of transverse weld seams and transverse detaching cuts, or of transverse detaching weld seams, on an intermittently pushed and/or intermittently carried tubular or semi-tubular web of thermoplastic synthetic resin and for stacking the detached sections, consists of a transverse welding and transverse detaching station for detachment of sections provided with bottom w...

A process for pad-steam dyeing of cellulosic fibres with reactive dyes comprising i) impregnating the cellulosic material first with alkali carbonate or bicarbonate (hereinafter "step i)") followed by ii) applying, wet-on-wet, a reactive dye solution (hereinafter "step ii)").

One end portion of a pipe, which has a circumferentially extending external bead at the one end portion, is insertable into the internal sockets of an array of arms which are axially movably received in one end portion of a sleeve. The arms have external surfaces which cooperate with an internal surface of the sleeve to permit limited axial movements of the arms between first and second positions....

This invention is for holding components made of a ferromagnetic material parallel to a component axis for electroplating the component. The component substrate according to the invention has at least two magnet poles, oriented toward the components and having opposite polarity. The magnet field lines extend from one magnet pole to the other magnet pole through the components only in the vicinity ...

Spacer supports are connected to a matrix of heat exchange tubes of a heat exchanger to maintain the heat exchange tubes in spaced relation and resist overheating by hot fluid flowing around the tubes and the spacer supports. The spacer supports are in the form of hollow tubular bodies in which the heat exchange tubes are supported in spaced relation. The heat exchange tubes communicate with the i...

This invention relates to an arrangement method of signal lines o1, o2, o3, o4 of a peripheral circuit of a memory array block within a chip in a semiconductor memory device wherein shield wirings S1, S2, S3 are inserted between signal lines, so that a noise transmission path caused by coupling capacitance between adjacent signal lines is cut off, and therefore, the noise generated at each signal ...

The purpose of this invention is, by using pedal cranks of variable dimensions, to achieve for the bicycle the advantages which can be provided by a changing of speed with infinite ratios, but which is impossible to achieve because of the difficulty of employing multiples and free wheels with enormous dimensions.
