A modular luminaire assembly including a top mounting assembly, an optical assembly removably affixable to the top mounting assembly and an electrical assembly removable affixable to the optical assembly where the optical assembly is mechanically coupled to the top mounting assembly by a quick disconnect.

2142589 9407054 PCTABS00030 A torque proportioning differential (10) is modified to vary bias ratio in three distinct stages in response to predetermined levels of drive torque. A pair of side gears (26 and 28) carried within a differential housing (12) generate respective thrust forces (44 and 46) that can be opposed by both high-friction gear mounting surfaces (68 and 70) and low-friction gear m...

Disclosed is a method and apparatus for the rapid identification of a solute of interest in an effluent stream. The method involves separation of the solutes in the effluent and identification of a particular solute of interest by its selective subtraction from the effluent stream.

A method of screen printing a hard non-absorbent substrate, such as glass, using a screen with a patterned coating on its surface facing the substrate comprises providing local support between the screen surface and the substrate in one or more areas in which a patterned ink layer of increased thickness is required, thereby enhancing ink retention in the said areas. The method is especially useful...

A vehicle window heating apparatus includes a heating element provided for heating a vehicle window when connected to a generator. The generator has a field winding fed from a voltage regulator connected to a vehicle battery. The apparatus also includes a circuit for connecting the generator selectively to one of the voltage regulator and the heating element. The circuit is responsive to a signal ...

Apparatus for center notching an insulated electrical conductor includes two pairs of cutting blades that circumferentially slice the insulation at predetermined locations along the insulated electrical conductor to thereby define a slug of insulation. A jaw with a knife edge is located in each of the four quadrants about the insulated electrical conductor axis. The jaws travel in respective recta...

The present invention provides a process for preparing halogenated sulfones by reacting a halogenating agent with a salt of a hydroxysulfone. The halogenated sulfones are useful as an intermediate for vitamin A or its carboxylic acid esters employed as medicines or feed additives.

The subject wideband switching network provides inexpensive point-to-point wideband communication connections. Wideband source (S1-Sm) and destination (TV1-TVn) terminal equipment are either connected to modems (SM1-SMm, DM1-DMn) which encode the analog signals used by the wideband source terminal equipment (S1-Sm) into digital signals for transmission through the wideband switching network and de...

A swept frequency theft detection system for detecting different resonant circuit targets (14) which are resonant at different frequencies. The system comprises arrangements to generate swept frequency transmitter signals centered at different frequencies but which are swept in synchronism. Also provided are antennas (16, 18, 20, 22) formed by offset loops, with the loops of different frequency an...

Adhesive containing (meth)acryloyloxyethyl dihydrogen phosphate and/or di(meth)acryloyloxyethyl hydrogen phosphate and acidic (meth)acryloyloxyethyl esters of carboxylic acids can be used to improve the adhesion of photopolymerisable dental filling materials to the enamel and dentine.
