Title: Flat knitting machines
IPC: D04B15/78
Filed: 1978-05-30
Abstract: There is provided a multiplex circuit (6), which according to the movement of the carriage, transmits signals to the needle-selection systems, in order to bring about the knitting of a knitted article with a pattern when control signals from a memory arrive at the multiplex circuit. In such a device, a variation in the working width from one row to the next should be simple and take place over the entire width of the bed of the flat knitting machine, without limit switches having to be mechanically adjusted. The change in the setting should also be as simple as possible. For this purpose, the memory is designed as a working memory (12) having storage locations which are assigned to the needles of the flat knitting machine over the entire width of the bed and in which the entire working width is stored. <IMAGE>

Abstract: 191,434. Rushen, P. C., (Rub-Tex Products Inc.). Sept. 15, 1921. Moulds; moulding hollow-ware.-A battery cell or other liquid-tight jar or container is built up of separate sheets of rubber, or a composition of rubber and fibre, which are vulcanized together in a mould, internal pressure being obtained during vulcanization by a three-part core 25, 26, 27, the central member 27 of which is wedge-shaped to permit easy removal. The mould, as shown in plan in Fig. 1, is made of four separable walls 11 which are held together by bolts and nuts 13 and' engage at their lower ends in grooves in a base 10 as shown in Fig. 2. The sheets 16, 20 to form the cell are arranged in the mould and overlap one another as shown in Fig. 1, partitions 19 being provided if the cell is to consist of a number of compartments. Each wall of the cell may consist of a number of superposed sheets, and each sheet may itself consist of a number of plies pressed together. The exposed sheet of each wall may consist of pure rubber or rubber of higher quality than the remaining sheets, or the walls may be of wood or other material covered with a veneer of rubber. The bottom surface of each member 25, 26, 27, of the core is provided with grooves into which the rubber flows during vulcanization to form electrode supports 31. The end walls 11 of the mould may have recesses to receive the ends of headed studs 34 which become embedded in the end walls of the cell and form means of attachment for handles.

Abstract: 1276361 Conveyers; orientating articles SORTEX BRETTEN Ltd 14 May 1969 [16 Feb 1968] 24578/69 Divided out of 1273972 Headings B8A and B8S Carrots and like tapered vegetables to be orientated for delivery to a topping machine, not shown, are delivered singly from a rotary table 33 on to an endless conveyer 36 with a plurality of transverse rollers 37 arranged between a pair of endless chains 38 whereby on rotation of the rollers, on their movement over a stationary plate 40, the carrots are caused to be orientated in a direction transverse of the direction of conveyance and in the gaps between the rollers 37. The conveyer 36 discharges the carrots on to a horizontal or inclined plate 41 across which the carrots roll to be received on a pair of endless wires 31 in the crown, that is heavy end, leading disposition. Disposed on opposite sides of the wires 31 are a pair of endless belts 44, 44a and a pair of wires or the like 43, 43a arranged to form a trough with increasing inclination of the sides in the direction of conveyance. The carrots are fed to the table 33 from a hopper (46), Fig. 3 (not shown), by an elevator (47) comprising a scraper conveyer extending inside the hopper and feeding the carrots to an endless belt which in turn feeds them to an endless conveyer (52) of similar construction to the conveyer (36) which arranges the carrots singly for feeding to the table (33). Alternatively the conveyer may directly feed the conveyer (36), as may the elevator (47). The elevator may feed a plurality of conveyers and may have openings (55) in the support base (50) to allow discharge at different levels. In a further embodiment, Fig. 5 (not shown), a vibratory conveyer (18) is disposed between the elevator (47) and a rotary table (19) to arrange the carrots in longitudinal alignment, the table (19) acting to turn the carrots through 90 degrees for feeding to the conveyer 36. In a further embodiment, Fig. 7 (not shown) carrots are fed to the upper end of a pair of parallel inclined rollers (57) rotating in opposite directions and on passage along the rollers become longitudinally arranged in the gap between said rollers. In a still further embodiment, Fig. 10 (not shown) a series of fixed guides (66) with angled faces 72 are arranged alternately with movable guides (68) connected to a swinging beam (69) such that the carrots are step-wise advanced with successive movements of the guides (68) to become transversely arranged for feeding to the conveyer 36.
