Abstract: 1,120,615. Sinks. D. S. COX. 27 Sept., 1965, No. 41070/65. Heading A4N. [Also in Division E2] A fastener device adapted to be mounted on a panel or on an appliance provided with a flange for releasably mounting the panel or the appliance on a mounting surface 24 of a mounting member, comprises a spring retaining member 16 having an opening 42 and adapted to be secured to the underside of the panel or the apppliance flange generally adjacent to the marginal edges of the mounting member, a spring 32 supported on said spring retaining member, said spring having one or more inwardly mounted portions 44 releasably held in fixed position in the opening in said spring retainer member, said spring having one or more outer portions, the or each of which is angularly formed and wedge in use against an underside of the mounting member or extension thereof to fasten said panel or said appliance flange to said mounting member, the or each outer portion of said spring being self adjusting in that it is movably supported by said spring retaining member, whereupon releasing the or each inwardly mounting portion of said spring from said fixed position will, in use, release the wedging contact of said outer portion or portions of said spring from the underside of the mounting member or extension thereof. As shown the appliance is a sink having a flange 18 and a plurality of the fastener devices, one of which is shown, are mounted on the flange, the spring 32, as shown, is made of wire and has two of the portions 44 each of which is joined to a respective outer portion 34; the outer portions in turn are connected to an intermediate portion 36 which is received in a slidable manner in a groove 38 of the retaining member so that the portions 34 can move when the springs are pushed into the aperture. The end portions of each spring are formed as hooks 40 and these normally engage the ends of the opening 42 in the retaining member 16; the end portions 40 however can be moved inwardly by manual pressure so that they are released from the ends of the opening and this enables the spring to tilt relative to the retaining member so that the portions 34 are disengaged from the edge 28 to enable the appliance to be detached from the mounting surface. To hold the spring in the releasing position the portions 44 are formed with a bend which becomes engaged with the ends of the opening 42. In a modification the spring is made of strip material and has a single outer portion and a single inwardly mounted portion; the end portion of the spring adjacent the outer portion is formed with notches in which edge portions of the opening in the retaining member engage so that the outer portion of the spring is slidable. The other end portion of the spring is formed with a slot which normally engages a portion of the retaining member which projects into the opening so that the spring is held in the gripping position to enable the slotted end portion to be disengaged from the projecting portion to enable the spring to be moved to releasing position.

Title: Improvements in or relating to Mechanical Latching Coordinate Switches
IPC: H01H67/26
Filed: 1966-09-15
Abstract: 1,161,506. Electric selectors; electromagnetic devices. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 15 Sept., 1966 [25 March, 1966], No. 41293/66. Headings H1L and H1P. In a switching matrix the moving contacts 10 at a cross-point are held off the fixed common vertical contacts 11 by a card 16 engaging a stop finger 12; the operation of a row bar 18 (only one of two being shown in Fig. 2A) moves the cards of a row by engagement with lugs 17 away from the stop fingers permitting the stop finger of a chosen cross-point to be attracted out of the path of the card upon subsequent energization of the relevant column magnet 13, enabling closure of the cross-point contacts upon release of the row bar and return of the card; the magnet then being de-energized. Re-operation of the row bar will release the cross-point and also any other operated cross-points of that row, but not of the column of the particular cross-point. Such a feature enables an inlet to one column of the matrix to be extended to a second outlet via another cross-point in the same column, as when making an offering connection. By introducing a delay into the operation of the column magnet a row and column can be pulsed simultaneously. The fixed and moving contacts 10, 11 and the column magnet 13 and associated yoke 22 are mounted upon a vertical plastics member 14, several of which are bolted together to form the matrix. There is described a matrix (Fig. 5, not shown) in which the fixed contacts of two columns are individual to each cross-point and the moving contacts of these columns are horizontally multipled to other moving contacts in the same row to give a preselective character to the matrix. The electromagnets 19 which operate row bars 18 have cores 19 and a common yoke 25 (Fig. 6) upon which are hinged the armatures 21.
