Filed: 1920-02-03
Abstract: 141,023. Tyner, R. H. April 3, 1919, [Convention date]. Laundry sorting-booths.-In an open-fronted sorting-booth for laundries, of the kind described in Specification 143,858, a permanent sorting and enumerating bar 18 for each customer is fixed between bars 11, 12 forming the framework of the booth, a blackboard 19 being provided above each bar 18 upon which is written the customer's name or mark. Each bar 18 carries a series of pivoted hooks numbered successively from the bottom upwards. Each hook consists of two loops 21, 22, Figs. 2 and 3, which may be swung up into vertical position when not in use. When required, the loops are pulled down into horizontal position, the article being held between the then contacting fronts 23, 24 of the loops. The number of articles on the hooks is readily ascertained by glancing at the number of the first unoccupied hook above the articles, the hooks being used successively from the bottom upwards. If the number of articles for any particular customer exceeds the number of hooks on the bar 18, an additional bar 35, normally hanging on a bar 40 outside the booth, is hung on bars 30 in front of the blackboard bearing that customer's name or mark. The hooks on this additional bar are numbered consecutively from the bottom upwards, the lowest number being that next above the highest on the bar 18. A folding shelf 16, supported on lugs 17, enables the lowermost articles on the hooks to be kept clear of the floor.

Abstract: 563,953. Milling-machines ; cutters. SHAKESBY, L., ROCK, K. S., McGLYNN, F. L., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 1, 1943, No. 3303. [Class 83 (iii)] In a process and apparatus for removing burrs from the edges of sheet, strip or shaped articles, the edge to be treated is subjected to the simultaneous action of two rotary cutters whilst supported adjacent the cutters and pressed into contact therewith. As applied to a sheet metal article 2, the article is passed between adjustable supports 7, 8 whose edges 9, 10 define a narrow channel to guide the article past toothed cutters 13, 14 rotated in opposite directions to act on both sides of the edge 1. Smooth portions 5 on the cutters rotate in contact with each other. The supports 7, 8 are recessed at 12 to accommodate the cutters and the shape of the channel between them is designed more or less to the shape of the article being treated, depending on the flexibility of the latter. The edge 1 is pressed against the cutters by a spring or weight-actuated roller 16 and may be traversed by hand or by driving the roller 16. The article rests on a plate 15 standing proud of the work-table 3 to allow for slight irregularities on its edge. The cutters are adjustable angularly and axially to suit the shape of edge required on the article 2. The rough edge of the article may be treated before it reaches the cutters 13, 14 by means of a rotary cutter let into the surface of the table 3 and a final burnishing tool may impart a polished edge to the article.

Abstract: 809,982. Plate rectifier assemblies. GENERAL ELECTRIC CO. Feb. 4, 1957 [Feb. 7, 1956], No. 3758/57. Class 37. In an assembly of rectifier cells, the separating contact members consist of cup-shaped metallic members 5<SP>1</SP> open at one end and closed but with an annular ridge at the other end. The arrangement facilitates cooling. The members 51 are in the form of truncated cones open at the top to form a rim 6<SP>1</SP> and recessed towards the centre at the base to form a ridge 71 at the edge. There is also a small central hole in the base. The radius of the rim is equal to the medial radius of the ridge. In use the ridge is placed in contact with the counter electrode of a selenium rectifier and a small hollow insulating collar 13 is pushed through a hole in the rectifier and member 5<SP>1</SP> the external diameter of the collar being such that the spacing element 51 is held in place. These cells may be assembled in a stack by threading them on to a bolt 16. Contacts 19 and 23 may be made by threading a suitable flat plate on to the bolt between the rim of element 5<SP>1</SP> and the baseplate of the adjacent rectifier. If it is desired to reverse one of the cells and to make a connection at the intersection of counter electrodes, a plate such as 21 with one annular depression is threaded on to the bolt so that the rim of an adjacent member 5<SP>1</SP> fits into the recession formed and the ridge on the plate contacts the counter electrode of the adjacent rectifier. An arrangement forming a full-wave rectifier is mentioned. The assembled stack may be encapsuled in a potting resin.
