Title: Liner assembly for particle-throwing apparatus
Inventor: HARPER WILLARD J
IPC: B24C5/06
Filed: 1983-04-08
Abstract: A wear liner assembly for lining front, rear, end and top walls of the guard housing of a blastant throwing wheel includes a plurality of liner plate members. The liner plate members have full-thickness edge portions which overlie or interfit with edge portions of adjacent ones of the liner plate members to define abrasive-tight labyrinth seals. A wrap-around corner joint connects end wall liner plate members with front and rear wall liner plate members, and facilitates replacement of broken or worn liner plate members. The liner plate members and the joint structures are configured such that selected ones of the liner plate members can be fabricated using either a relatively thin section of relatively brittle cast metal or a relatively thick section of relatively ductile cast metal. One embodiment of the invention includes plates having an edge configuration such that less expensive mounting structure can be used, as well as a more effective abrasive seal for the region of the wheel shaft. Lugs may be provided on the plate members adjacent the discharge opening of the housing to prevent abrasive particles entering the region between the liner members and housing. <IMAGE>

Title: Mounting electrical components on rails
Inventor: SOMERFIELD ERIC ALBERT
IPC: H02B1/052
Filed: 1984-01-10
Abstract: A mounting assembly for the mounting of electrical contactors on a "din rail", comprises a mounting plate secured to a contactor (6), the mounting plate comprising a relatively rigid securing member (30), and a relatively resilient securing member (32) clipped over the mounting rail. The mounting plate has two parts, each secured to one of two body parts of the contactor, and each capable of undergoing relative movement, enabling the interior of the contactor to be accessed without removal of the contactor from the mounting plate. The mounting plate comprises means (50) accessible from the exterior of the mounting plate, to release the resilient securing member (32) from the mounting rail. A resilient support member (36) urges the securing member (32) against movement in a release direction, to hold the securing member in a position in which it retains the mounting plate on the mounting rail, should the resilience of the securing member fail. <IMAGE>

Title: Knitted fabric separating machine
Inventor: CLARKE FREDERICK
IPC: D04B19/00
Filed: 1987-04-02
Abstract: The invention relates to a machine for the separation of knitted fabric into discrete portions by the effective removal of thermo-degradable threads linking the portions, the machine comprising a conveyor 10 and infra-red radiation tubes (78, 80, Fig. 5) in a unit 4. The output of the tubes is controlled in accordance with the rate of progress of the fabric through the machine, and/or the nature of the fabric. Steam may be supplied at 38 to supplement the action of the heating tubes. Roller 32 is driven at a surface speed proportional to, but less than, the speed of the conveyor 10 so that once a band of link threads has disintegrated, the discrete portion of knitted fabric on the conveyor can move away from the fabric held by rollers 32, 34. The lag of the roller 32 relative to the conveyor 10 is adjustable, by means of compensating pulley 116, to vary the spacing between the discrete portions. <IMAGE>
