In the moulding of insulating bodies, a fibrous glass web 17 impregnated with melaamine, epoxy or phenolic resin is wound on a perforated mandrel 10 coated with wax, and the whole placed in a two-part 36, 38 hinged, perforated mould. A latch 42 holds the mould in a closed position. The latch may be operated automatically by electrically or mechanicallycontrolled cams. The lower mould half is mounted on a plate 29 secured to links 45 of the conveyer chain 46, which carries the moulds into a hot air oven 20. Flaps 52, 53 allow the moulds to enter, whilst sealing the entrance 55 against outward flow of air. Parts of the mould may be left imperforate to promote transverse flow of hot air. In a modification (Figs. 5, not shown), the moulds may travel vertically through the oven and the hot air is arranged to flow in two directions. In a further modification (Figs. 6 to 9, not shown), the moulds are mounted on a drum which rotates within a cylindrical oven.

Title: Gas pressure generators and power plants including such generators
IPC: F02D19/02
Filed: 1935-10-14
Abstract: 467,561. Fluid-pressure servomotorcontrol systems. PESCARA, R. P. Oct. 14, 1935, No. 28334. Convention date, Oct. 15, 1934. [Class 135] [Also in Group XXVI] In a power plant made up of a constant pressure gas generator and a consuming machine e.g. a turbine, regulation is carried out by a device for controlling the pressure in the compresser together with means dependent upon a working factor of the consuming machine for regulating the supply of a working fluid. In an arrangement for carrying this out, Fig. 3, the oil pressure in line 34 is controlled through a relay 33 by the governor 10. As the turbine speeds up the pressure in line 34 rises and causes a spring loaded piston to open valve 43 which lowers the quantity of air delivered to the turbine. The reverse happens when the machine slows down. The supply 34 to the loaded pistons 4<2> and 4<1> is controlled by a valve attached to a rod 28 which is only open when the pressure above the spring loaded valve 26 is down to a predetermined value. This pressure is controlled by the pressure in the discharge line of the preceding generator. This device is not fitted to the last generator brought into action, so that valve 4<3> is controlled by the governor only. When the speed rises and valve 4<3> is fully opened, the pressure in line 3<3> falls and line 34 is connected to the operating piston of valve 4<2> which is then under direct control of the governor. The starting and stopping of the generators 1<2> and 1<3> is carried out automatically by the pressure in pipes 25<2> and 25<3> controlled from the discharge line of the preceding generator. The Specification as open to inspection under Sect. 91 comprises also a modification in which a variable feed generator is used. If the load varies the speed of the machine 2, Fig. 3 (Cancelled) varies, the governor 10 acting through slide valve 20 and relay 19 alters the position of throttle valve 17 and generator fuel injection pumps 16 to suit. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,078,304. Waveguides. LIGNES TELEGRAPHIQUES & TELEPHONIQUES. July 10, 1964 [Aug. 6, 1963], No. 28472/64. Heading  H1W. In a waveguide for the propagation of the fundamental circular TE or TM mode a number of fine conductive wires are positioned in a dielectric tube along lines following zero components of the electric field of the desired mode TE or TM, whereby the other mode TM or TE is suppressed. The invention may be applied to a waveguide solely comprising a dielectric tube 8, Fig. 6, or rod, with or without a surrounding metallic shield 7. The guide shown is intended for the circular TM mode and includes fine circular wires 10, of e.g. copper, embedded in the high-permittivity tube 8 and in the low-permittivity spacers 9, the wires being effective to suppress the TE circular mode. In the case of a guide intended for the TE mode, radial or longitudinal wires are embedded in the dielectric tube for suppression of the TM mode. A similar guide (Fig. 7, not shown), propagates the so-called circular TM "dielectric mode " and, in addition to the circular TE mode, it is necessary to suppress the circular TM mode guided by the shield 7. This so-called " metallically-guided " mode has a longitudinal component which is non-zero at a radial position where the corresponding component of the desired dielectric mode is zero. Thus, a series of short, fine, longitudinal wires lying in a cylindrical surface of the required radius may be used to suppress the metallically-guided mode. These longitudinal wires (16, Fig. 7), may lie inside the wall of the dielectric tube 8. They may coincide with the circular wires 10, in which ease both sets of wires are replaced by a mesh. The wires may be located in the dielectric tube or rod by a process in which the tube or rod is extruded in layers, the wires being sandwiched between the extrusions. Radial wires may also be used for suppressing modes having a radial electric field component.
