Title: Improvements in and relating to the production of artificial threads from viscose
IPC: D01D10/04
Filed: 1948-04-30
Abstract: <PICT:0640750/IV (a)/1> <PICT:0640750/IV (a)/2> In an apparatus for the production of rayon from viscose the threads 21 (Figs. 1 and 2), from a number of spinning jets are led from a spinning bath (not shown) to a series of individual godets 2 carried by parallel shafts 20 and arranged in echelon in a horizontal plane.  They are then led to a second series of individual godets 3 carried by parallel shafts 20 and also arranged in echelon in a horizontal plane, each thread travelling the same distance between the godets through a common trough or troughs 1 containing treatment liquids and so shaped and of such a length that each thread receives a treatment uniform with that of the other threads, and of such width that each thread is accessible to the operator throughout the treatment.  Each common trough in plan view may present the appearance of a parallelogram either having two of the parallel sides longer than the other two and the obtuse angles several times the size of the acute angles, Fig. 1, or having all the sides equal and one diagonal several times the length of the other.  As shown, the threads 21 pass round one of the godets 2 through slots 18 in one end wall 4 of tank 1 and along the channel 11 of the platform 10 in the treatment zone 6.  A 1 per cent sulphuric acid solution flows from the reservoir 12 along the channels 11 and completes the regeneration of the threads.  The latter then pass through slots 18 in the partition 8 and into the channels 15 of platform 14 in treatment zone 7.  A washing liquid flows in counter-current to the travel of the threads from reservoir 16 and the used liquid runs into the waste compartment 17.  The washed threads leave the treatment zone 7 through slots 18 of partition 9 and pass through slots 18 of the other end wall 4 of tank 1 on to the godets 3. The threads then pass to individual drying reels (not shown) and are finally collected as packages on holders by cap spinning devices (not shown).  Specification 489,781 is referred to.

Title: Improvements in or relating to oscillator synchronizing circuit arrangements
Inventor: BALDWIN JOHN LEWIS EDWIN
IPC: H04N5/12
Filed: 1959-04-09
Abstract: 944,161. Automatic phase control systems. RANK-BUSH MUBPHY Ltd. April 11, 1960 [April 9, 1959], No. 11977/59. Heading H3A. An oscillator is synchronised by sync pulses applied to open a diode gate circuit and sample the instantaneous (positive or negative) value of a balanced sawtooth wave derived from the oscillator, the integrated output of the gate circuit phase locking the oscillator so that the sync pulses and midpoint of the long flank of the sawtooth waves coincide. Further, the gate circuit has resistive or time constant means 40 connected across its diagonal, or in one or both of the sync inputs to the gate circuit to limit, during out of synchronism, the change in voltage across output capacitor 26 occurring at sawtooth flyback instants so that instead of the output across capacitor 26 being a sawtooth balanced about zero voltage with sharp flyback, the output flyback is partially suppressed and a .D.C. component arises of polaity indicating the relative sense of the frequency slip (difference frequency) between the sawtooth and sync inputs and speedily restoring frequency equality. The charge limiting resistors may be replaced by constant current devices, e.g. pentode valves, or non-linear resistors. The system may be applied to synchronizing television receiver scanning.

In a ventilator used as a directional control device for an air distribution outlet, a rectangular, e.g. square, frusto-pyramidal casing 1 having sloping side walls 2, is connected by a neck extension 4 to a branch duct 5 of a primary supply air system and is positioned within the square opening 9 in the ceiling 10 of an enclosure to be ventilated. Disposed within the confines of the casing 1 are four deflector plates d1, d2, d3, d4 of right isosceles triangular shape. These deflectors are suspended from a pair of crossedsupport straps 11 and 12 detachably mounted to the casing 1 by screws 16. Four pivotal connections or hangers 17 are connected to the support straps, such as by welding, and each deflector is pivotally attached to the horizontally fixed bar 19 of its respective hanger 17 by a bearing clip 23 in a tight frictional engagement. Each deflector can be individually adjusted from the fully open position as shown in Figs. 1 and 2 to the fully closed position when the bottom edge 25 of the deflector abuts against a side wall 2. As shown in Fig. 1, in the open position the air flows through the neck 4 to the passageway 27 formed between a deflector and its respective side wall, and then through a diffuser plate 28 into the enclosure. Flanges 35 are attached to the side walls of each deflector so that when in a closed position no air will be discharged straight downwardly through the diffuser 28. In another embodiment (not shown) the opening is rectangular and the casing 1 is a truncated rectangular pyramid. In this case two opposite deflectors are triangular in shape and the other two have a trapezium shape.
