Title: Braces for reinforcing mesh structures
Inventor: BOGAR BELA
IPC: E04C5/06
Filed: 1990-05-21
Abstract: Accurate and rigid spacing of mesh and rods for reinforcing concrete can be achieved using a brace which is adapted to support, at each of its ends, the orthogonal rods of a reinforcing mesh structure. The brace comprises two parallel steel rods 50, spaced apart by spacing bars 59, 60 welded to the rods. Outwardly of the spacing bars, the rods are formed into pairs of hook legs which include a retention region 56 within which a reinforcing rod may be located. An orthogonal reinforcing rod fits between the hook legs, bearing against the adjacent spacing bar 59. In a preferred embodiment, support legs 65 are attached to, or formed integrally from, an extension of the lower hook legs of the brace. The support legs enable the reinforcing mesh structure to be spaced away from the ground on which the support legs are placed. In a further embodiment (fig. 16-18) pairs of hooks are provided at the ends of a single single rod (70, 90). <IMAGE>

Abstract: The invention finds particular application in radio testing equipment. There is known radio testing equipment wherein the updating by a display system thereof of the displays of a series of sequentially occurring displays provided in testing by the equipment, is undesirably slow. The present invention provides a display system which overcomes this problem. The invention has four aspects. in the first aspect the present invention provides a display system having a dual processor architecture wherein one processor (49, 51) modifies a drawing sequence executed by the other processor (53, 55). In the second aspect the present invention provides a display system which, to display each next display of the series, modifies the contents of memory locations for a previous display by addressing and changing the contents of substantially only those memory locations the contents of which is required to be different for the next display to the previous display. In the third aspect the present invention provides a display system wherein the characterisation of each pixel (65) of a display screen (61) is determined by a number stored in a corresponding memory location of a memory (55), and each number comprises a number of parts each of which corresponds to a respective one of a plurality of distinct features comprising each display. In the fourth aspect the present invention provides a test equipment which, with a view to providing a series of frequency spectrum displays, includes a frequency synthesiser (203, 205 or 301, 303) which steps the frequency generated thereby. The synthesiser (203, 205 or 301, 303) indicates when each frequency is achieved by providing a synchronisation signal to a display system (21, 23, 25) which in response to receipt thereof receives a further signal in the provision of which the frequency was utilised. <IMAGE>

Title: An inking assembly for a printer
Inventor: LIU HSING-JEN
IPC: B26F1/06
Filed: 1992-06-05
Abstract: The assembly serves to supply ink from two inking rollers (8', 9') to a reciprocating plate cylinder (12') (which is reciprocated between positions C and D), by way of two transfer rollers (602', 702'). The transfer rollers are movable along respective arcs A-A', B-B' so that when one roller is in contact with the plate cylinder the other contacts an inking roller, and vice versa. This allows two applications of ink to the cylinder for each reciprocation of the cylinder. The transfer rollers are driven by rods (404', 504') coupled to the ends of two lever arms (402', 502') which rotate about a common axis (400', 500'). Control of the arms is via followers (403', 503') which run on a horizontally reciprocated cam track (301'). <IMAGE>
