Abstract: A lighting apparatus comprises a housing having an opening, a light source received in the housing and a light transmitting-cover (12) fixed at the opening of the housing and through which light rays are projected from the light source. The light transmitting-cover (12) includes a plate made of light transmitting-material and having a first surface and a second surface. Segment lens elements of the same size are arranged on the first and second surface of the plate and formed integrally with the plate. The segment lens elements on the first surface (33A) are positioned in face-to-face relation with the segment lens elements arranged on the second surface (33B), thus forming a segment lens (31). The segment lens elements have a common optical axis (32) and convex surfaces (33A, 33B), respectively. The focal lengths defined by these convex surfaces (33A, 33B) are equal. The focal point of one of the segment lens elements lies on the convex surface of the other segment lens element, and that of the other segment lens element lies on the convex surface of the other segment lens element.

Abstract: A document processing system including a digital image capture system, character recognition circuitry, document encoding systems, endorsers, audit trail printers and an in-line microfilm record system enable documents to be read, endorsed, encoded, digitally imaged, filmed and sorted in a single continuous pass through the document processor by way of a modular transport system. The encoding of the continuously moving documents is accomplished by a plurality of fixed dies, electronically controlled hammers, and an ink bearing ribbon interposed between the documents and the fixed dies. Scanning and digitizing of the documents is effected by continuously transporting the documents across the focal plane of stationary scanner where the documents are repetitively scanned in a single axis, two scanners being employed to permit scanning and digitization of both sides of a particular document in a single pass through the transport mechanism. The system includes apparatus for visually displaying an image which corresponds to a plurality of stored digital values, the apparatus including an image memory and circuitry enabling the display to be partitioned into discrete portions of variable sizes. Additionally, circuitry is provided which allows image rotation, mirror imaging and discrete video attribute selection within each portion of the display. Video data compression apparatus and method are employed for use in minimizing the amount of data necessary to store and recall a black and white video image.

Abstract: The quaternary ammonium monomers of this invention have the formula
     wherein
     R is an ethylenically unsaturated organic group   R is a linear C 1  to C 4  alkyl group, optionally hydroxy substituted   X is chlorine, bromine or iodine, and   Y⊖ is a surfactant anion.   
     The epoxides derivable from the halohydrin of Formula (I) are other monomers of this invention. 
     The monomers are soluble in common organic solvents and comonomers. The invention is also directed to addition polymers of these monomers and to methods of producing both the monomers and the polymers. The halohydrin monomers and the polymers are stable at acid pH values although capable of reacting with materials reactive with the hydroxyl and/or halide groups. Upon heating, they are self-reactive and can become cross-linked. At alkaline pH values they become self-reactive; the polymers crosslink slowly even at room temperature, with a crosslinking rate increasing rapidly with temperature. The monomers are particularly efficiently incorporated into copolymers. Polymers containing the novel monomers are useful as coating, binding or impregnating compositions.

Abstract: © A process and associated apparatus for the cooling of hot fluidized solid particles. The particles flow through conduit (4) from a dense phase fluidized bed into the shell side of a vertically oriented shell and tube heat exchanger (3) where cooling occurs via indirect heat exchange with a cooling media circulating in the tubes. The extent of cooling is controlled by operating the cooling zone dense phase with sufficient backmixing to control the heat exchange coefficient between the heat exchange means inserted in the cooling zone and the dense phase fluidized bed. The coefficient is varied by varying a combination of the variables comprising the quantity of fluidizing gas to the fluidized bed in the heat exchanger and the quantity of particle flow through that bed. The process has particular applicability to a combustive regeneration process and most particular applicability to the FCC process.

Abstract: The flexible cable supplies power to movable equipment with rated voltages up to 1,000V., esp. hand-held tools, and has three wires twisted together and sheathed in a plastics or rubber sleeve. The two wires (1,2) that carry current have an outer layer (3) composed of electrically-conducting plastic or rubber. The third wire (the ground wire) is either a plain wire or a wire (4) covered in an electrically-conducting plastic or rubber layer (5). The outer sheaths of all three wires are electrically connected since they touch one another. A break in one of the current-carrying wires - a break causing a failure in the insulation - results in the current-carrying wire being electrically connected to the ground wire. A fuse between the ground wire and the current wires (and located in a plug) therefore burns out.

Abstract: It is known to form an integral plastics material mesh structure by punching a square or rectangular pattern of holes in a starting material sheet, and then stretching. Particularly when the material is stretched biaxially, irregularities occur across the structure. In order to avoid such irregularities, the strand-forming zones 3,7 are formed with depressions 13,14 with the sheet at ambient temperature, prior to stretching. This is found to greatly improve the regularity, as well as increasing through-put speeds and decreasing power requirements, particularly with polypropylene.

Abstract: An electric arc welder has a current-conducting means which can supply welding power to an arc along a first volt- ampere curve, has a second current-conducting means which can be paralleled with the first current-conducting means to supply welding power to that arc along a second and distinctly-different volt-ampere curve, has a voltage-sensing circuit which senses the arc voltage, and has a control circuit which automatically and virtually-instantaneously shifts the supplying of welding power from a point on the first volt- ampere curve to a point of essentially-equal potential on the second and distinctly-different volt-ampere curve when the voltage-sensing circuit senses that the arc voltage has fallen below a predtermined value. That control circuit will subsequently shift the supplying of welding power from a point on the second and distinctly-different volt-ampere curve to a point of essentially-equal potential on the first volt-ampere curve when the voltage-sensing circuit senses that the arc voltage has risen above that predetermined value. In this way, a welding wire or welding rod can be continually advanced toward a weld puddle in a work piece, and the welding power which is supplied along the second and distinctly-different volt-ampere curve will transfer the tip of that welding wire or welding rod to that weld puddle without "shorting" and thereby extinguishing the arc.
