Abstract: Curved reflecting surfaces on a rotary scan component produce an aiming spot of enhanced visibility during a single scan line mode of operation for an electro-optical reader capable of reading bar code symbols in a multiple scan line mode of operation.

Abstract: A nozzle assembly includes a readily replaceable nozzle tip which is replaced within a firnace adjacent an installed furnace-side end of a supply nozzle. The nozzle tip is provided with a pair of opposed, spring-loaded pivot pins which snap into apertures in the wall of a stationary nozzle conduit to removably secure the tip to the conduit. The pivot pin connection permits tilting of the tip relative to the stationary conduit in a vertical plane about a horizontal axis extending through both pivot pins. A link arm used for tilting the nozzle tip has a hook-shaped end which connects to a pin extending from the nozzle tip. The hook-shaped end of the link arm permits removal of the nozzle tip without having to remove the link arm from a lever assembly.

Abstract: A push broom handle brace for supporting the connection between the handle of a push broom and the broom head of the push broom. The push broom handle brace includes an elongate member having opposite first and second ends. The elongate member has spaced apart first and second middle bends defining a pair of elongate side portions and an elongate middle portion. The first and second side portions each have an end bend positioned towards the adjacent end of the elongate member. The end bend of the first side portion and the first end of the elongate member defines a first end region therebetween. The end bend of the second side portion and the second end of the elongate member defines a second end region therebetween. Each of the end regions has an aperture therethrough for extending a threaded fastener therethrough into the base block of the broom head of the push broom to couple the end regions to the base block of the broom head of the push broom.
