Title: Improvements in or relating to textile doubling machines
Inventor: WARRINGTON CLIFFORD
IPC: D01H13/18
Filed: 1956-03-07
Abstract: 805,434. Stop-motion for textile doubling machines. TWEEDALES & SMALLEY (1920) Ltd. March 7, 1957 [March 7, 1956], No. 7119/56. Class 120(2) In a textile-doubling machine, to allow auxiliary mechanism for rendering the stop-means inoperative to be moved into position when one or more of the stopmeans are in the operative position, the mechanism comprises a series of yieldable resilient members, such as leaf springs or spring-mounted fingers. In each section of the machine are provided a group of rollers such as 16 associated with a series of threads above a common driven roller 10. Each roller 16 is supported by a cradle comprising two plates 27 pivoted at 26. A thread guide 36 is carried by a pivoted lever 37, and while the tension is maintained in the thread, the parts are held in the position shown where a tail 32 on a plate 27 engages a notch 39 on the lever 37. When the thread snaps, the lever 37 which is weighted at 34 swings downwardly so that the notch moves away from the tail which then engages a slot 41 and the roller 16 is moved away from the roller 10 on to a bar 20. To render this arrangement inoperative, e.g. when it is desired to stop the machine, a bar 42 may be rotated by a handle so that a series of springs &c. 44 engage the corresponding levers 37 to stop them falling and to retain the parts in position. The springs &c. are such that if the bar is rotated when one or more levers have fallen, the corresponding spring or springs will flex without affecting the position of the lever(s), while the other springs will perform their normal retaining function. The bar is rotated by a handle mounted in a forked end of the bar: the handle is held behind a stop in the operative position by the pressure exerted on the springs by the weighted levers 37.

Title: Improvements in and relating to the vacuum distillation of materials yielding a solid distillate or residue
IPC: B01D3/10
Filed: 1934-03-07
Abstract: <PICT:0435032/III/1> In the high vacuum distillation of materials yielding a solid distillate or residue in apparatus wherein the distilling surface 4 and condensing surface 5 are in close proximity, the solid is removed, for example, from the condensing surface by a scraper 7 in the form of a piston ring traversing the surface by means of a screw 8 and is delivered to a receiver 2.  The apparatus or the surfaces in question are tiltable to prevent fouling of the distillate and residue.  In a modification, the material to be distilled, falls down a fixed vertical surface 3, Fig. 2, and the solid is removed, for example, from the condensing surface 4, by a knife blade 9 carried by geared rings 7 and 8 rotated about the vertical axis of the still by pinions 10, the solid being delivered to a receiver 12.  The residue may be removed from the distilling surface in a similar manner.  Suitable distillations comprise the extraction of caffeine from ground coffee beans, quinine from quachia bark and the purification of crude b -amino-anthraquinone.

In one form, the package has a dividing seam 14 made by dealing the sides to an inner strip The strip may be of differing material such as chlorinated rubber, laminea such as of polyethylene 36, 37 with porous tearable material 35 between. It may be simply a polyethylene strip produced by a method different from that by which are produced the package envelope films, the seam between these being weaker than between identical materials. Dissimilar polyethylene laminea may be so used. A three compartment container may be formed by sealing between the films, a tube 75 the material of its wall being readily rupturable. The invention may be used as a containing and mixing means for electrical insulating compositions.
Patent GB-597216-A (GB)
Title: Improvements in or relating to ultra high frequency apparatus employing wave guides
IPC: H01P1/213
Filed: 1944-04-20
Abstract: 597,216. Wave-guides electric resonators. ALLEN, W. D. April 20, 1944, No. 7368. [Classes 40 (iii) and 40 (v)] The flow of energy along a wave-guide is controlled by a resonant conducting ring arranged inside the guide. The ring may act as a filter, an adjustable matching device or as a switching device. Fig. 5 shows a resonant ring arranged in a circular wave-guide, At the resonant frequency, this acts as a series resonant circuit shunted across the guide and gives complete reflection of H 1 waves. For rectangular guides, a rectangular ring with rounded corners is used. The circumference of the ring is somewhat greater than the wavelength in air, and depends on the thickness of the ring and the diameter of the guide. A diaphragm having an annular gap in place of the metal ring acts as a parallel resonant circuit shunted across the guide. The rings may be used as filters and are described as used for this purpose in the E0 to H1 transformers shown in Specifications 597,217 and 597,240 (Figs. 7 and 8, not shown). A ring which is somewhat smaller than the resonant size can be made to resonate when turned about an axis which is normal to the E vector and the axis of the guide. If either a full-sized ring or a smaller ring is rotatably mounted in a guide it can be used as a variable reactance. When parallel to the axis of the guide it presents negligible susceptance. Rotatable rings can thus replace adjustable pistons. Fig. 10 shows a pair of rotatable rings 4, 5 mounted in matching stubs 8, 9 to replace pistons. The rings are rotated until matching is effected. Fig. 13 shows a coaxial feeder 1, 1<1> supplying energy to waveguide 2 or 3 according as ring 4 or 5 is parallel to or normal to the axis of the guide. The rings are simultaneously rotated through 90 degrees by turning the common spindle. A similar arrangement is described for deflecting energy through one or other arm of a Y-shaped guide by means of a single rotatable ring arranged at the junction of the arms (Fig. 14, not shown). The rings may be embedded in polythene to reduce the likelihood of sparking. This slightly modifies its properties. Specification 597,212 also is referred to.

Abstract: 552,107. Heating and filtering liquid fuel. SEDDON, R. H. June 2, 1942, No. 7440. [Class 7 (iii)] For use as fuel in an internal combustion engine, palm oil, ground nut oil, cotton seed oil and the like and waste lubricating oil are heated and filtered before admission to an injection pump. Fig. 1 shows a combined heater and filter in which a container 1 for the oil is traversed by pipes 5 through which exhaust gases are conveyed to an outlet 23 after having entered through a pipe 26 containing a throttle valve 28 under the control of a heat-sensitive device, not shown, in the container 1. Pressure is maintained in the container by air supplied through a passage 2. A filter 15 communicates with the interior of the container through a pipe 19 and discharges through a pipe and passage 16, 27. When forced from the container by compressed air the hot oil traverses the filter and is conveyed to an engine injection pump, not shown. Diesel oil is used in the engine for starting purposes. If it is passed through the tank the exhaust gases are bypassed through a valve 29.

Abstract: 1,175,089. Cathode-ray tubes. FUNKWERT ERFURT, VEB. 17 Feb., 1967, No. 7598/67. Heading H1D. An indirectly heated cathode includes a cathode tube, of substantially rectangular cross-section, disposed perpendicular to the beam axis and having an emissive area formed on one of its longitudinal faces, the cathode tube being supported by a hollow tube, of a length substantially equal to that of the cathode tube, which is secured to the centre of the face of the cathode tube opposite to that bearing the emissive area; the arrangement minimizes heat loss, and is suitable for a transistorized cathode-ray tube arrangement. The emissive material 2 is applied to the central section of one face of the cathode tube 1, which extends in a direction perpendicular to the electron beam, and is supported at the centre of its opposite face by being spot-welded to the flanged end of a hollow tube 3, of comparable length to the cathode tube, which extends coaxially within the hollow tube 12, to which it is connected by spot-welding at the crease 14 and punch marks 13. The tube 12 carries at its top a channelshaped reflector 11 which surrounds the non- emissive faces of the cathode tube, and houses a cathode lead. The assembly is mounted within an annular ceramic member (Figs. 1 and 2, not shown) through which pass leads to the cathode heating resistor via the ends of the cathode tube, and the top of which serves as a stop, when inserting the cathode assembly into an electron gun, whereby precisely to predetermine the position and spacing of the emissive surface with respect to the electron-optical system.
