Title: Sack formed from double ply woven fabric - having filament inserted in warp direction to form a tie around sack mouth
IPC: B65D30/06
Filed: 1973-12-21
Abstract: A double ply fabric is woven with pref. the plies joined together along one edge and with a tying filament inserted in both plies in the warp direction along the other edge. At spaced transverse zones the two plies are joined together by the weft yarns and the fabric is cut along the median line of the zones to form separate socks. The cut ends of the filaments inserted in each sack are fused together to form a tie around the mouth of the sack. The sacks are used for vegetables partic. potatoes. The insertion of a tying filament (which is thicker than the other yarns used for weaving) is simpler by inserting it in the warp direction than by inserting it in the weft direction which is conventional. The tying filament is also inserted more uniformly.

Patent FR-2298111-A1 (FR)
Title: Measuring effective value of electrical signal - is achieved by comparing rectified signal with areas under sawtooth waveform
IPC: G06G7/20
Filed: 1975-01-16
Abstract: The effective value of an alternating, periodic or random voltage is measured by generating a proportional continuous voltage and comparing it with the areas under sawtooth waveforms of opposing polarity. A signal voltage (x) is rectified (r) and one output is applied to a comparator (2) whose second input is obtained fro a sawtooth generator (3) which also provides an input for a second comparator (4). The second input of this comparator receives a continuous voltage from an integrator (7) which is also the output voltage (5). Both comparator outputs are applied via an Or-gate to a switching circuit (5) which operates when the sawtooth reaches the rectified signal voltage causing integration to occur. Successive integration of the waveform occur at sawtooth frequency until equilibrium is achieved when the output is proportional to the effective value.

Title: Synchronising system for two motors - has phase detectors determining dependent motor braking to return synchronisation
IPC: H02P5/52
Filed: 1975-02-21
Abstract: The synchronising system, for two synchronous motors, has two phase detectors to detect the respective angular positions of the shafts of the two motors. The phase signals are passed to a control circuit which alters the running of one motor if these phase signals show that the motors are asynchronous. When the signals are once again synchronised the motor is returned to normal running. The dependent motor is slowed by a friction brake when it gets out of synchronisation with the master motor. The synchronising system was developed for controlling the motors which drive rotating mirrors in spectral photometric equipment.

Filed: 1976-01-23
Abstract: Fibres and filaments comprise a terephthalic acid copolyester, the acid component of which contains 1-10wt.% of 1,10-decanedicarboxylic acid. The copolyesters are prepd. from terephthalic acid in admixt. with 1-10wt.% 1,10-decanedicarboxylic acid and pref. also 1-10wt.% 5-sulphoisophthalic acid by reaction with ethyleneglycol, 1,4-bis OHMe-cyclohexane or 1,4-butanediol.
