Title: Improvements in or relating to ammonia stills
IPC: C01C1/10
Filed: 1952-02-29
Abstract: <PICT:0722336/III/1> In the steam distillation of ammonia liquor in a bubble tray fractionating column, some of the vapours rising from the uppermost tray are withdrawn from the column and introduced into a lower section thereof by means of a steam injector or a fan blower. The upper trays of the column may be cooled by supplying cold water or cold liquor to the uppermost tray, or by means of a cooling coil immersed in the liquid in the uppermost tray. Preheated ammonia liquor is supplied to column C, which has ten trays, through pipe L. The liquor descends the column against an ascending current of steam which is introduced through pipe S. The effluent liquor, stripped of ammonia, is discharged through pipe E.  The ascending mixture of steam and ammonia gas is gradually enriched with respect to ammonia as it bubbles through the upper trays of the column.  Some of the vapours from the top compartment 11 are withdrawn, and introduced by means of a steam injector or fan blower F into compartment 2 of the column via pipe P.  The remaining vapours rising from the uppermost tray are withdrawn from the top of the column through the central outlet. Cold water may be circulated through coil W, and/or cold water or cold liquor may be introduced onto the upper tray through pipe D, so as to maintain the head temperature at about 85 DEG C.

Title: Improvements in pleating devices
IPC: D06J1/00
Filed: 1929-02-18
Abstract: 326,635. Stewart, W. H. Oct. 31, 1928, [Convention date]. Pleating.-An apparatus for forming various types of pleats in cloth in the piece and also in endless pieces such as skirts, comprises a frame with removable frame members and with removable pleat-forming blades, the frame having a well portion beneath for housing steam pipes. The pipes are for heating and admitting steam to the fabric as a moistening agent. As shown a series of pleating blades 56, Figs. 1, 3 and 5, are inserted above and below the fabric A, the remainder of the fabric not being operated upon hanging down and in the case of a skirt enveloping the frame as shown in Fig. 3. The pleating blades are maintained in position on removable and interchangeable end plates 36, 38 by bars 58, 60 which enter eyelets 52 on bars 50 dovetailed in an end plate 44. The plates 36, 38 and 44 are detachably secured to a frame 20 provided with a rectangular open top well 22 in which is situated looped heating coils 28. A perforated steam pipe in the centre of the well admits steam to the fabric. In operation, and commencing at one end, one of the pleating bars is placed over the fabric and is followed bv a second bar placed underneath and alongside the first bar. The second bar is placed over the first bar, thereby looping the fabric. This process is repeated with the pairs of bars until they are all in position, whereupon steam may be admitted. A supporting plate 63 may be used for supporting the fabric as a pressing iron is passed over the cloth. If more fabric is required to be pleated, the pleating bars in operation are removed except those above one of the end plates 36, say. The plate 36 with its bars in position are all moved bodily to take the place of the plate 38 and its bars and the pleating is then continued from this position onwards. A presser foot 65 holds the cloth and bars in position and is itself held in position by a U-spring 66. In a modification, for accordion or like pleating the fabric B, Fig. 9, is pleated by bars 56, 56<a> pressed in position by a presser bar 92 closed on the bars by a screw-threaded rod 94. The fabric is supported by a screen 90. In another modification, the cloth is supported by a conveyer or belt to obviate the necessity of the removal of one of the side plates to the other side of the frame. In a further modification, the pleating bars are carried bv a flexible frame so as to conform to the curved top of a pressing table.

Title: Transmission gearing including means for measuring torque
Inventor: CHAMBERLIN REGINALD HENRY DOUG
IPC: F16H1/28
Filed: 1953-02-27
Abstract: 743,418. Dynamometers. NAPIER & SON, Ltd., D. Feb. 26, 1954 [Feb. 27, 1953], No. 5628/53. Class 106 (2). A dynamometer, Fig. 1, for indicating the magnitude of the torque being transmitted by a driving shaft 11 to a driven shaft 16, comprises a sun wheel 10 on the shaft 11, planet pinions 12 meshing with the sun wheel 10, the planet pinions 12 being carried by a spider rigidly connected to the driven shaft 16, a smaller planet pinion 17 coaxial and rotatable with each planet pinion 12, and an internally toothed annular reaction ring 18 meshing with each planet pinion 17. The annular reaction ring 18, Fig. 3, has projections 23 extending radially outwards therefrom, these projections being disposed in between co-operating projections 24 extending radially inwards from a fixed annular ring 22. The projections 23 and 24 co-operate to form a substantially watertight pocket therebetween, every alternate pocket being connected to a common group of' fluid inlet ports 29, and the remaining series of pockets to a common group of inlet ports 30. Fluid under pressure is supplied to these pockets through additional ports arranged such that when the torque reaction ring 18 tends to move in either direction, it opens ports permitting the pressure fluid to enter whichever of the series of pockets pressure is required to resist such torque reaction, while communication between the other fluid inlet control ports and fluid pressure ports tends to be cut off, and exhaust ports associated with this other series of pockets tend to open. Thus a difference in the fluid pressure in the two series of pockets is automatically maintained as roquired to resist the torque reaction at any moment, this pressure difference being indicated by a differential pressure gauge as a measure of the torque at any instant.

Abstract: 564,858. Sound transmitting apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 2, 1941, No. 5724. Convention date, June 5, 1940. [Class 40 (iv)] [Also in Group XL] An electron discharge device for producing high frequency oscillations and communicating them to a waveguide 16, Fig. 1, comprises a source of a density-modulated electron stream including a first closed resonant chamber 12 in which the stream is velocity-modulated, a second closed resonant - chamber 20 forming part of the wave-guide and directly coupled, as by aperture 19, to the remainder thereof and having a gap 22 arranged in the path of the stream for extracting energy therefrom, and means such as the movable diaphragm or piston 23 for varying the volume of the second chamber to vary the resonant characteristics thereof in accordance with a modulating signal. A third chamber 14 may obstruct a portion of the energy of the stream and feed it back to the first chamber through the line 15 for self-excitation. The second chamber may be tuned to the same frequency as the first and third chambers or to a harmonic ; the piston 23 produces amplitude modulation when working on the side of the resonance curve. In a modification, resonators 12, 14 and 20 are coaxial cylinders in contact, the gaps being formed between tubes passing through the separating partitions. Coupling between resonators 12 and 14 is by a small hole in the partition between them. In a further modification, the beam passes transversely across two concentric cylinders, the inner one forming the second chamber 54, Fig. 4, and the outer being separated diametrically by system 63 into the first and third chambers 51, 53 respectively, coupled by gaps 62 near the inner wall. The functions of the second and third chambers are combined in the form shown in Fig. 5 into the resonator 65 which is coupled to the wave-guide 67 by aperture 68 and tapered portion 70. The volume of chambers 64, 65 is simultaneously varied by piston 66, so that frequency modulation is produced ; all three chambers of Fig. 2 may be simultaneously varied with a similar result. In a modification chambers 64, 65 are separate and their tuning pistons are coupled mechanically. If the electron beam is in the form of a ribbon, the gaps and all the dimensions of the resonators may be elongated in the direction of its width. The couplings apertures 19, 68 are sealed by glass or mica and may be followed by an iris diaphragm to enable the coupling to be adjusted.
