Title: Improvements in the manufacture of twist-lace net
IPC: D04C5/02
Filed: 1921-07-19
Abstract: 186,466. Farmer, J. July 19, 1921. Lace.-Filet or square-mesh net is made on plain-net machines with two half sets of warps the threads A, B of which twist together and envelop pairs of bobbin threads C to form the vertical bars of the net. The horizontal bars C<1>, C<2> are formed from two bobbin threads which are traversed by the movement of the front comb bar. The warps B may be reversely twisted or the twisting of all the warps may be reversed at intervals. When both tiers of carriages are at the front, the back guide-bar carrying the threads B traverses one gait to the left while the front guide-bar carrying the threads A traverses one gait to the right. When both tiers are at the back both bars return to their initial positions. When one tier is at the front and the other is at the back both guide-bars stand. The work is taken up at each motion, instead of at longer intervals as is more usual, in order that the twist in the vertical bars may be evenly formed. The traverse of the carriages may be effected by moving the front comb bar one gait to the left every four, six, &c. motions, while both tiers are at the front, and by moving it two gaits to the right when the back tier has moved into the back combs. An alternative manner of traversing the front comb bar is described.

IPC: G01F15/075
Filed: 1966-05-05
Abstract: 1,124,525. Measuring flow. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. 5 May, 1966 [10 May, 1965], No. 19859/66. Heading G4H. The variable-frequency output of a flow meter is corrected by the periodical addition of extra pulses or the suppression of pulses. If the anticipated error is negative, a counter supplied with the meter output opens a gate, e.g. every 100 meter pulses, to inject pulses from an oscillator until a further counter registers a predetermined count. If the anticipated error is positive, the meter pulse counter is arranged to block the meter output, e.g. every 100 meter pulses, and to supply the meter pulses to a further counter until this counter reaches a predetermined count, thus suppressing the predetermined number of meter pulses. A selector switch may enable either positive or negative error correction to be chosen. A further embodiment enables the number of pulses added or subtracted from the meter output to be varied in accordance with the momentary frequency of the meter output, the sign of the correction also being determined by this frequency.
