A connector assembly for use with a unitary daughter board having different contact pitch arrangements on the lower edge portion, includes two different contact pitch arrangement connectors lengthwise aligned and juxtaposed with each other for commonly receiving the lower edge portion of the daughter board. The connector of the high density contact arrangement includes an outer end wall having a recess at the top for functioning as a pivoting point of the rotative movement of the daughter board ...

Oligosaccharides are structurally characterized utilizing enzymatic digestion with an array of highly specific exoglycosidases followed by electrochemical detection and measurement of the molar quantity of cleaved monosaccharides in each enzymatic digest.

A digital system for indicating the quantity of fuel in a vehicle comprises a signal detecting device and a digital displaying device. Fuel which remains in a fuel tank of the vehicle or fuel which is consumed in the running of the vehicle is measured by the detecting device, and a signal of the detecting device is introduced into the displaying device for indication in a digital manner.

A cigarette lighter built with a flip-out windshield having one corner edge hinged to the lighter body. The windshield is normally folded in and concealed in the lighter body when not in use, and is then flipped out to protect the flame from wind when in use.

Methanol is separated from formaldehyde aqueous mixtures by contacting the aqueous mixture feed with a first surface of a polymeric membrane selectively permeable to the methanol over the formaldehyde or formaldehyde and water; while maintaining a second and opposite membrane surface at a lower chemical potential than the first membrane surface for the methanol permeating a portion of the methanol into and through the membrane, and withdrawing from the second membrane surface a mixture having a ...

A differential pore-collapsed separation membrane particularly useful as a gas-separation membrane and a method of preparing such differential pore-collapsed membrane, which method comprises treating an asymmetric membrane, while under one-sided constraint, with a treating solution comprising a volatile nonsolvent and a swelling agent and/or a solvent, and drying the treated membrane, to provide for the controlled, differential pore collapse of the small pores of the top skin of the membrane to ...

The present invention relates to an improved wind-bell of the seated type comprising of at least two or more blades, a central rotating axle, a striking bar, sound-producing bars, dragging means, a frame and a base plate. The blades are connected to the central rotating axle which is inserted through a bore at the center of the frame into a hollow stationary post secured to the base plate. A plurality of sound-producing bars are provided with hooks on both ends thereof, with hooks on the upper e...

A toy having an upright toy body standing on a pair of skis to resemble a skier. Each ski is provided with a driving wheel operable by an electric motor in cooperation with a driving mechanism built within the toy body to rotate so as to enable the toy to roll on a ground surface. The toy has two hands each holding a ski pole, the two hands being operable by the same electric motor in cooperation with an alternating pivot lever to move alternatingly up-and-down while the driving wheels are cause...

An improved opening lock for use in a sunshade or a parasol which is housed in a cavity defined on the shaft of the sunshade. The present opening lock has a stop block having a smoothly curved guide bottom at the front end and a bias spring disposed behind the stop block and a fixing element for mounting the spring, and a cover plate which confines the stop block and the spring and the fixing element inside the cavity so that the runner of the sunshade slidably disposed on the shaft is able to m...

A test lead socket indicating device is used for a volt-ohm-milliammeter (VOM) having a select input which is operable to set the VOM in a voltage, current or resistance measuring mode, a common input socket, a voltage socket, a resistance socket and a current socket. The test lead socket indicating device includes an indicator unit provided on the VOM and having a voltage indicator lamp disposed adjacent to the voltage socket, a current indicator lamp disposed adjacent to the current socket and...
