Title: Apparatus for controlling the tension of a magnetic video tape
IPC: G11B20/02
Filed: 1969-05-05
Abstract: 1,216,624. Automatic control of tape tension. AMPEX CORP. May 5, 1969 [May 6,1968], No.636/70. Divided out of 1,216,623. Heading G3R. [Also in Division H4] In a system for controlling the tension of a magnetic tape during playback of a recorded television signal subject to periodic signal dropout intervals, e.g. due to the mode of tape scan employed, means are provided for controlling the tape tension in response to signals indicative of any phase change which may have received in the horizontal synchronizing pulses just before and just after each drop-out interval. In the embodiment a phase comparater 204 produces as error signal for application to a brake 294 as the tape supply reel, the inputs for the comparator 204 being provided by a circuit 199 supplying a signal indicative of the horizontal synchronizing pulses, which are absent during the drop-out interval, and a horizontal-pulse-frequency controlled oscillator 202. The oscillator 202 provides an output throughout the drop-out interval essentially in phase with the horizontal pulses immediately prior to drop-out. A feedback loop 206 couples the error signal from the comparatar 204 to the oscillator 202 to reduce it to a predetermined level. An inhibit gate 222 in the circuit 199, controlled by the oscillator 202, ensures that only the horizontal synchronizing pulses are supplied to a monostable multi-vibrator 224. A further inhibit gate 230 is controlled by four-line duration pulses from a generator 262 timed so that the output from circuit 199 is blocked for a period commencing shortly before and extending into the drop-out interval, thereby to prevent noise immediately preceeding the dropout interval from degrading the error signal. A gated integrator 208 receives the output from circuit 199 and supplies a signal indicative of the presence and termination of the drop-out interval due to the absence for a predetermined time of horizontal pulses from the output of circuit 199. This indicative signal, differentiated and modified by a multi-vibrator 254, controls and pulse generator 262 and also controls a sample-andhold circuit 210 which ensures that the sampled signal is a reliable indication of the variation in tape tension even if the drop-out interval terminates during a horizontal synchronizing pulse.

Abstract: 191,726. Fischer, E. Jan. 10, 1922, [Convention date]. Paper bags, making.-Relates to machines for printing and making paper bags of the type with broken-off corners. Paper is fed from a roll 2, Fig. 1, which is positively rotated, to form a loop 5 and passes between stretching-rollers 3, 4 and over a smooth cylinder 6 co-operating with a printing roller 7. The cylinder 6 is intermittently rotated from the main driving roller 36 by bevel gearing, and the roller 7 is lifted at intervals by a lever 17 and cam 18 but not sufficiently far to disengage it from an adjustable toothed sector driving it intermittently. Feeding rollers 19, 20 supply ink from a container 21. The paper passes between rollers 24, 25 the latter of which applies glue, and over a roller 26, at which point it may be reinforced by a second strip of paper &c. from a roll 28. The paper is formed into a tube over a plate 27, Fig. 2, and is fed forward by the roller 36 and rubber rollers 85 acting in recesses 34 in the plate. A knife 47 severs the tube a little in advance of the plate 27, and a blade 57 and a corresponding lower blade apply glue to the upper and lower sides of the end of the tube at the moment of severance. The blade is actuated by a rod 63 and a system of links 59, 61, 65. A flexible blade 74 on the plate 27 causes the end of the paper tube to gape and a folder having a hose 66 and a heel 67 enters the end of the tube and folds it back into the position shown in Fig. 8, the end a<1>, b<1>, c<1>, d' of the plate defining the folds a, b, c, d.

Filed: 1975-01-08
Abstract: 1494671 Transmission systems SIEMENS AG 8 Jan 1975 [18 Jan 1974] 708/75 Heading H4R Data exchanged between a first station Ul and a second station not shown is accompanied by a pilot whose frequency depends on the state of the transmission path in the opposite direction and which is detected to automatically raise the upper limit of a pilot band-stop filter when the pilot frequency exceeds a predetermined value. Pilots of 300, 315 or 330 Hz indicate that none or either of duplicate send and receive lines such as B1, B2 and Cl, C2 is faulty. The pilots are transmitted below the data band which starts at 360 Hz and are detected to change over a switch at the remote station to connect to the non-faulty line and return an appropriate pilot to U I to change over a similar switch 10. The filters such as 22 attenuate the pilots by 40 dB to prevent interference in monitoring the band below the data band. If both lines are faulty a pilot of 345 Hz is transmitted and this is detected to switch impedances in the filters to raise the cut-off to 360 Hz.

Title: Improvements in or relating to a method for insolubilising artificial filaments, threads, fibres and the like of regenerated protein
Inventor: MCGILLIVRAY ROY
IPC: D01F4/00
Filed: 1955-01-12
Abstract: Insolubilized artificial filaments are produced from a bundle of regenerated protein filaments (obtained by spinning an aqueous solution of natural protein into an aqueous acidified saline coagulating bath followed by an aqueous saline relaxing bath), by treating the bundle with an acidified aqueous solution having a pH up to 4 (preferably 1.5 to 3) of at least one salt, said salt being such that, if the bundle is immersed in an aqueous solution thereof and then washed and dried, it contains discrete filaments, then treating the bundle with an acidified aqueous solution of formaldehyde in the presence of at least one of the salts at a pH not over 3.0 (preferably not over 1.5), washing the bundle free from salts, impregnating the filaments of the bundle with an acidified aqueous solution of formaldehyde which is free from salts, stretching the filaments, holding the filaments in the stretched condition while undergoing drying at least for such a period of time that they no longer tend to shrink, and heating the bundle while the filments are free to relax to a temperature and for a time to effect insolubilization.  The salts may be alkali metal salts of hydrochloric, sulphuric or phosphoric acid, or ammonium, magnesium or aluminium, sulphate or sodium zirconyl sulphate.  The salt solution should preferably have a concentration of over 5 per cent and may contain, for example, 24 per cent of sodium sulphate, 20 per cent of magnesium sulphate and 6 per cent of aluminium sulphate or 10 per cent of sodium zirconyl sulphate.  The formaldehyde solution may contain 10-20 grams of formaldehyde per 100 cc. of solution.  The drying of the filaments may be effected at 15-160 DEG  C. and insolubilization at 140-220 DEG  C.  In an example a bundle of filaments formed by spinning a solution of groundnut protein is stretched 400 per cent in a coagulating bath, relaxed in a bath containing 24 per cent of sodium sulphate and 2.5 per cent of sodium chloride at pH 8 to 9 for 5 minutes at 25 DEG  C., treated in a bath containing 24 per cent of sodium sulphate adjusted to pH 4 with sulphuric acid for 10 minutes at 70 DEG  C., then treated in a bath containing 24 per cent of sodium sulphate and 1.5 per cent of formaldehyde adjusted to pH 2 with sulphuric acid for 5 minutes at 50 DEG  C., washed with water and dried at 80 DEG  C.  The filaments are then impregnated with a 10 per cent formaldehyde solution brought to pH 1.0 with hydrochloric acid, mangled, stretched 300 per cent in air, dried while stretched at 80 DEG  C. until they no longer tend to shrink, and heat-treated for 30 minutes at 160 DEG  C., while free to relax. Specifications 513,910, 533,952, 597,497, 605,830, 623,460, 642,359, 741,497, 742,261, 742,890, 758,560, 770,662 and 785,881 are referred to.
