The present invention relates to a lighting device, which comprises a structure of interconnected sleeves and a light emitting arrangement arranged inside the sleeves. The structure forms a polygon mesh and light sources on the light emitting arrangement can be positioned by the structure so that the problem of glare can be reduced. The present invention also provides a sound-absorbing, flexible and collapsible structure which can be used in e.g. large scale architectural panels, horticulture and phototherapy devices. The lighting device can be produced by connecting the sleeves with thermoplastic material or by sewing.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. Centering protrusions of one housing can engage the other housing to initially retain the pin retaining receptacle of the inner housing in a central position within the interior of the outer housing in the Y-direction prior to insertion of the pin into the pin retaining receptacle. The other housing can be movable against the centering protrusion to permit the pin retaining receptacle of the inner housing to move out of the central position in the Y-direction in response to engagement of the pin against the entry ramps during insertion of the pin into the pin retaining receptacle.

A manufacturing process for making different expansion tanks for different cooling systems and/or for different engines, each of the expansion tanks having an inlet mouth and comprising: a plastic shell comprising a) a wall defining a cavity for containing a coolant liquid; and b) at least one collar at the inlet mouth, the collar being outwardly projecting from the wall. Each of the expansion tanks further comprising a tubular insert engaging the collar and defining the inlet mouth; the tubular insert being made of plastic material; and retention means which hold the tubular insert relative to the collar. The process comprising making shells identical in shape and size, for all of the expansion tanks; and making inserts that differ in the value of their inner diameter; each inner diameter value being determined at the design stage depending on the type of cooling system and/or the type of engine.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. The pair of inner housing retaining surfaces can engage the pair of cooperating inner housing retaining surfaces, with the pin retaining receptacle of the inner housing extending into the interior of the outer housing, to slidably couple the inner housing and the outer housing together while permitting movement of the inner housing relative to the outer housing in a Y-direction in response to the inner housing moving in the Y-direction during insertion of the pin into the pin retaining receptacle. Associated methods are also disclosed.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. A plurality of centering blades extend into the interior and between the inner and outer housings to locate the pin retaining receptacle in a central position within the interior in a Y-direction prior to insertion of the pin into the pin retention receptacle. The centering blades are movable in the Y-direction to permit the pin retaining receptacle of the inner housing to move to a non-central position relative to the housing in the Y-direction as a result of the inner housing moving the centering blades in response to the pin engaging the entry ramps during insertion of the pin into the pin receiving receptacle. Associated methods are also disclosed.

An expansion tank for a cooling system of a motor vehicle has an inlet mouth and is provided with a shell in plastic material having a wall which defines a cavity for containing a coolant liquid; the shell has, in addition, a projecting collar, at the inlet mouth, and a first inner tubular wall, which protrudes downwards into the cavity and defines a passage with a lower outlet opening, to make the coolant liquid flow into the cavity; the shell has, in addition, a second tubular wall, projecting upwards into the cavity and defining a compartment which is vertically aligned with the passage and has an upper overflow opening vertically arranged at a height that is equal to or greater than that of the outlet opening.

A method of assembling a tapping sleeve includes positioning an outlet band on a pipe element with an arcuate portion of the outlet band contacting an outer surface of the pipe element, the outlet band including a front end, a back end, a first side end, a second side end, a first bend line defined between the first side end and the second side end and extending from the front end to the back end, a second bend line defined between the first bend line and the second side end and extending from the front end to the back end, wherein the outlet band defines an arcuate portion between the first bend line and the second bend line, a first flange defined between the first side end and the first bend line, and a second flange defined between the second side end and the second bend line.

A tapping sleeve includes a first bend line in a planar outlet band between a first side end and a second side end of the planar outlet band, the first bend line extending from a front end to a back end of the planar outlet band, a first outlet flange defined between the first side and the first bend line; a second bend line in the planar outlet band between the first bend line and the second side end, the second bend line extending from the front end to the back end of the planar outlet band, a second outlet flange defined between the second side and the second bend line; and an arcuate portion formed between the first bend line and the second bend line.

Provided in this disclosure is a method for manufacturing a customizable holster. Steps are provided of molding inner holster components, including molding internal surfaces that conform to shapes of respective portions of a desired firearm design. Other substeps include molding external surfaces that conform to the shape of portions of an external mating surface of an inner holster. The inner holster components are mated to form an inner holster having an internal contact surface that conforms to the firearm design, to securely receive and retain a respective firearm within the inner holster. An outer holster is molded having an interior defined by an internal mating surface that conforms with the external mating surface of the inner holster. The inner holster is then mated to the outer holster such that the external mating surface of the inner holster is received within the internal mating surface of the outer holster.

A plastic container includes a first portion including an outwardly extending peripheral flange and a second portion including an outwardly extending peripheral flange. The first portion and the second portion define a container volume. The plastic container also includes a hinge joining the peripheral flange of the first portion and the peripheral flange of the second portion. The hinge includes a pivot line and two arcuate segments proximate to respective ends of the pivot line. The pivot line is tangent the peripheral flange of the first portion and tangent to at least a portion of each arcuate segment. The flange of the first portion can extend further than the flange of the second portion proximate each end of the pivot line to create a seamless periphery about the hinge relative to a periphery of the first portion when the container is closed.
