A dipstick comprises a blade (1) having a handle (4) connected to one end of the blade by means of an intermediate resilient tubular collar (3), said one end of the blade and said collar being provided with first formations (10,11) that cooperate as a snap-fit when said one end of the blade is inserted into the collar thereby to retain the two axially together, and said handle having a central aperture (5) to receive the collar as a close fit and said handle and said collar being provided with s...

A measurement instrument has a plurality of operation levels with different respective sets of operational functions associated therewith. Each operational function has at least two independently selectable characteristics related thereto. When an operation level of the instrument is selected, the instrument displays the characteristics related to each operational function associated with the selected operation level, and the operator is able to select one characteristic related to the or each o...

An apparatus to indicate a low level of liquid in a vessel, such as an automobile crankcase. A light-emitting diode and a phototransistor are coupled at the crankcase so that the light received by the phototransistor varies with rising or falling oil levels. The diode has a given maximum current rating. A unique pulse generating circuit applies a short duration, high-current pulse to the light-emitting diode to produce a correspondingly short but intense burst of radiant energy that is received ...

A liquid level sensor system well suited for sensing the level of fuel in aircraft fuel tanks includes a plurality of capacitive sensors which provide an output capacitance that is a function of the fraction of the sensor wetted by the fuel. A plurality of sensors are positioned in the liquid-containing tank with each sensor having a first and at least a second probe-specific liquid-quantity profile corresponding to a first and at least a second attitude of the tank. The capacitance of the senso...

A board game is disclosed which includes an octagonal-shaped playing board having a plurality of marked spaces along the periphery of the board and a plurality of casino games disposed in the central portion of the board. The plurality of marked spaces define a path of progression during play and include written or graphic indicia corresponding to selective options and directives for the players. The marked spaces having indicia corresponding to selective options either permit a player to purcha...

The present invention is a method for lowering serum levels of Lp(a), thereby reducing the risk of atherosclerotic disease. Specifically, the present invention comprises administering an effective amount of a N,S-diacyl-L-cysteine to a human or animal with elevated serum levels of Lp(a). The N,S-diacyl-L-cysteines comprise a compound selected from the group having the formula: ##STR1## wherein R is selected from the group consisting of hydrogen and an alkyl group containing 1 to 8 carbon atoms a...

Certain derivatives of oxophthalazinyl acetic acids of the formula ##STR1## wherein R.sub.1 is hydroxy or a prodrug group, and R.sub.2 and R.sub.3 are independently hydrogen, fluoro, chloro or trifluoromethyl, except that R.sub.2 and R.sub.3 are not both hydrogen, or a pharmaceutically acceptable base addition salt of a compound of formula I wherein R.sub.1 is hydroxy, are capable of lowering blood uric acid levels in mammals. These oxophthalazinyl acetic acid derivatives are for instance useful...

A method for achieving long term relief from the symptoms of atopic allergy, comprising parenteral administration of Vitamin B.sub.12 to selected patients, is produced. Vitamin B.sub.12 acts to reduce the levels of reaginic antibody (immunoglobulin) in these patients, and this effect persists beyond the period of treatment. The regimen may include oral administration of Vitamin B.sub.12 as well as other vitamins.

A system for analyzing the ion level of a fluid sample including an analyzer instrument, containing electrical circuitry for analyzing the ion level of the fluid sample, in electrical communication with a sensor unit having an ion selective electrode in communication with the fluid sample and electrical contacts for communication with the analyzer instrument. A recharger unit for the analyzer instrument is also disclosed.

Masterbatch including at least about 65 wt % of resin having a R&B softening point as measured in accordance with ASTM 28-67. The masterbatch also includes a carrier polymer having a peak melting temperature, as measured by DSC, up to about 20.degree. C. greater than the R&B softening point of the resin. A masterbatch pellet made by a method, including mixing a resin having a R&B softening point as measured in accordance with ASTM 28-67, and a carrier polymer having a peak melting temperature, a...
