Title: Dispersion devices for centimetric and millimetric electromagnetic wave energy
IPC: H01Q15/02
Filed: 1954-12-06
Abstract: 771,621. Waveguides. MARIE, G. R. P. Dec. 6, 1954 [Dec. 14, 1953], No. 35234/54. Class 40 (8). [Also in Group XL (c)] A channel separator for resolving the various frequencies within a given bandwidth in the centrimetric or millimetric region comprises a waveguiding dielectric lamina of non-uniform thickness arranged to behave like an optical spectrograph by virtue of the fact that the phase velocity and, consequently, the index of refraction of the guided waves are functions of the thickness of the lamina. A theoretical relation, illustrated graphically in Fig. 2, connecting the free-space wavelength #, the guided wavelength #g and the thickness a of the curved dielectric plate 15, Fig. 6, is derived in the Specification. The curve C applies to waves whose electric field is parallel to the surface of the plate and the curve C<SP>1</SP> to waves whose electric field is perpendicular to the plate. Upon the plate are mounted a series of dielectric prisms 18, 19, 20 of total thickness a+a<SP>1</SP> and of angle # within which the guided waves have a wavelength #<SP>1</SP>g. The angle of deflection of the waves # is given by #=(#<SP>1</SP>g/#g - 1)#, from which, by differentiation, the following expression for the dispersion is obtained: By manipulation of the equations it is shown in the Specification that the derivatives d#g/#g, d#<SP>1</SP>g/#<SP>1</SP>g and d #/ # may be expressed in terms of the thicknesses a, a+a<SP>1</SP> and the slopes d(#<SP>1</SP>g/#)/d(a+a<SP>1</SP>/#), d(#g/#)/d(a/#) of the linear portions of the curves C or C<SP>1</SP>. Radiation to be analysed is fed to the prisms 18, 19, 20 from a plano-convex dielectric lens 16 of thickness a+al whose convex side is in the form of a hyperbola having asymptotes which coincide at the apex G of a radiating horn 14. If the asymptotes make with the axis of the horn an angle # where cos #=#<SP>1</SP>g/#g the lens converts the spherical wave front coming from G into a plane wave front leaving the flat face of the lens. After dispersion by the prisms the various frequency bands are focused into separate receiving horns 21, 22, 23 by a second planoconvex lens 17. The plano-convex lenses may be replaced by bi-convex lenses (Fig. 4, not shown) having a focal length F given by where R 1  and R 2  are the radii of the faces. In the modification shown in Fig. 8 the curved dielectric plate 38 has a constant wedge-shaped cross-section. It is required that the components of a plane wave applied to the end face 39 should follow circular paths and that the guided wavelength #g should be proportional to the radius of these circles and hence to the thickness a of the plate which is proportional to this radius. This can be achieved by utilizing the linear portions of the curves C and Cl. The Specification gives a theoretical analysis of this construction and an expression for the resolving power is derived. The spherical wave radiated by the horn 14 is converted to a plane wave either by a bi-convex lens or by inclining the face 39 of the plate.

Abstract: 847,964. Gyroscopic apparatus. VYZKUMNY A ZKUSEBNI LETECKY USTAV. Nov. 13, 1957, No. 35382/57. Class 97(3) An erecting system for a gyro-vertical consists of outer and inner gimbals; a first spherical segment suspended to pivot about and to slide along the major gimbal axis; a second spherical segment similarly suspended with respect to the minor gimbal axis; slots in the segments inclined to the planes through the rotor spin axis and the respective gimbal axes; a pin, mounted on the bottom of the rotor casing, which engages the slots to shift the segments when the spin axis departs from the vertical, and means returning the segments under gravity to their initial positions. As shown in Fig. 1, the rotor casing 1 is suspended by trunnion pins 3, 4 in the inner gimbal 2 to rotate about the minor axis x. The gimbal 2 is suspended in an outer gimbal 5 for rotation about an axis y (not shown) at rightangles to axis x. A spherical segment 14 connects weights 12, 13 pivoted about and slidable along the axis x, and has a slot 15 into which a pin 16, mounted on the underside of the rotor casing 1, extends. Segment 14 carries a pin 17 extending into a slot 18 in a pendulum 19 which is suspended on separate bearings about axis x, and keeps the segment 14 vertical. Slot 15 is inclined to the plane containing the rotor axis and the axis y, so that when the rotor casing tilts about the axis x, the pin 16 causes the segment 14 and the weights 12, 13 to move along the axis x, thus setting up a couple due to gravity about the axis y which causes a precession about the axis x to restore the rotor axis to the vertical, in which position the weights 12, 13 and segment 14 are balanced about the axis y. A similar pair of weights and slotted spherical segment 22 (not shown) are similarly mounted on the axis y, and engage pin 16, to restore the rotor axis to the vertical after rotation about the axis y. These weights are also connected by a segment extending over the casing, and having a pin entering a slot in an inverted segment connected to pendulum weights 27 mounted on separate bearings about the axis y, so as to keep the segment 22 vertical.

Abstract: 1,099,395. Rotary retorts. HOLCROFT & CO. Aug. 23, 1965 [Sept. 28, 1964], No. 36046/65. Heading F4B. An automatic rotary retort furnace 10, for the batch heat treatment of small metal articles in a controlled gas atmosphere, comprises an outer gas tight refractory lined metal casing 20, and an inner metal retort 104 provided with longitudinal ribs 110, and freely mounted on parallel rollers 42, 44 which serve as a friction drive means to rotate the retort. The drive mechanism for the rollers is mounted on a stand 80 attached to the front of the casing 20 and comprises motor 134, speed reducer 122 and combinations of sprockets, shafts and chains (Figs. 8, 9) to transmit the rotary motion to the rollers 42, 44. A secondary drive mechanism, including an over-running clutch (152, Fig. 8), is also provided to transmit motion from the motor 134 to the retort 104 in the event of slipping occurring between the retort 104 and the rollers 42, 44. In this event the motion from roller 42 is transmitted through the clutch (152), which is only activated when the slipping occurs, and a sprocket and chain system (Figs. 8, 9) to a shaft 150 extending parallel to the rollers 42, 44 and having a gear wheel 156 on its end which engages with a rack 157 on the retort 104 to rotate it. The rear end of the retort 104 is driven by similar rack and gear wheel mechanism 182, 190 from roller 44 through a transmission system (Figs. 2, 12) mounted on the rear end 32 of the furnace casing, but including friction clutch 194, operative to drive the retort 104 whether or not slipping is occurring between the retort 104, and the rollers 42, 44. In normal non slipping operation gear wheel 156 is kept in meshed engagement with rack 157 by having motion transmitted to it from roller 44 through a friction clutch (178, Figs. 8 and 9) but this adds only a small driving force to the retort 104 compared with the friction drive from rollers 42, 44, whilst clutch (178) is de-activated to break the transmission, whenever over-running clutch (152) is activated to transmit driving motion from the roller 42. The retort 104 is heated by gas or oil fired U tube radiant heaters 112, or else electrically. Methane, supplied by piping (not shown) is circulated within heating chamber 22 and retort 104 by a fan (not shown). Parts to be heat treated, are charged intermittently into the retort 104 through shoot 228 which may be sealed by a pivotable door 232. The door 232 carries an auxiliary shoot 250 which is inserted into the mouth of shoot 228 whenever door 232 is automatically opened by fluid motor 258. Discharge is effected by tilting of the whole structure 10 so that the parts fall through shoots 260, 262 into quench tank 264. Tilting is effected by drive motor 202 which through a sprocket and chain drive causes rotation of the furnace trunnions 34, 36 in bearings 38, 40 respectively on base pedestals 12, 14. Refractory bumper elements 268 within the inside ends of casing 20, prevent excessive longitudinal movement of the retort 104 during tilting.
