Title: Flexible waveguide of oval corrugated tube
IPC: H01P3/14
Filed: 1964-09-11
Abstract: 1,072,327. Waveguides. TELEFUNKEN PATENTVERWERTIWGS G.m.b.H., and HACKETHAL - DRAHT - UND KABELWERKE A.G. Sept. 11, 1964 [Sept. 18, 1963], No. 37254/64. Heading H1W. Optimum dimensions, as regards attenuation and flexibility are chosen for a flexible, corrugated waveguide of oval cross-section intended for transmission of a plane polarized wavemode. A dimension A w , the " effective major axis," is defined by the expression: where a 1  is the major axis of the guide measured between the inwardly extending ridges of the corrugations, a 2  is the major axis measured between the grooves of the corrugations, t 1  is the depth of the grooves measured in the direction of the major axis (t 1 = (a 2  - a 1 )/2), and K 1  is a corrective factor lying between - 0.65 and +0À65 dependent upon the shape of the grooves. A dimension b w , the " effective minor axis", is similarly defined. According to the invention, the dimensions of the waveguide are chosen so that the ratio b w /a w  lies between o.5 and 0.8. In the graph of Fig. 7 (not shown) the abscissae represent the ratio b w la w  and the ordinates represent the working frequency relative to the cut-off frequency of the guide. A line (G) represents the upper limit of the pass-band, defined by the lowest frequency at which unwanted modes appear, and a line (E) represents the lower limit chosen to be 20% above cut-off. The lines (A) and (C) represent signals having a 10% band-width respectively transmitted in guides for which b w /a w  is chosen for minimum attenuation and for maximum flexibility. An optimum waveguide affording both good attenuation and good flexibility may have a ratio b w /a w  equal to 0.6 and transmits a signal represented by line (B). The corrugations may be helical and preferably have a pitch angle of between 0 and 60 degrees. The pitch angle may vary along the axis of the guide (e.g. between - 10 and +10 degrees). The depth of the corrugation may be different in the directions of the major and minor axes but both values are preferably less than 0À2a 1 . The profile of the corrugations may be sinusoidal, in which case K 1 =0. If the ridges of the corrugations are broadened, the corrective factor K 1  is positive and if the grooves are broadened the factor is negative (Figs. 4, 5 and 6, not shown).

Title: Improvements relating to fittings for tubular electric lamps
IPC: F21V11/06
Filed: 1946-12-18
Abstract: 633,090. Tubular-lamp fittings. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and GRIFFITHS, W. F. Dec. 18, 1946, No. 37272. [Class 75(iv)] A louvre for a tubular electric lamp fitting consists of an assembly of corrugated strips set vertically on edge and parallel to one another with the crests of adjacent strips abutting. The louvre is supported in the lamp fitting below the lamp with the strips parallel or transverse to the longitudinal axis of the fitting. The strips may be made of metal, glass, wood or plastic material and are formed into a rigid structure by means of bolts or rivets passed through abutting crests but when made of metal the strips may be spot welded at some of the abutting crests. In another method suitable for strips which have straight parallel abutting crests tongues in one strip engage holes in a contiguous strip. Alternatively the strips may be slotted on to cross members supported by the lamp housing or they may merely rest on such cross members and be maintained in position by fitting tightly in a light framework. Apertured lugs may be provided on the outside strips for attaching the louvre to the lamp housing. Two louvres one with strips transverse to the lamp, the other with strips parallel to the lamp, may be fitted one beneath the other. When the corrugations are made angular to provide a honeycomb structure the alternate crests and troughs may be of different lengths. In the Provisional Specification it is stated that cross members supporting the strips in a retaining frame pass through the crests of the corrugations and can be tensioned so to eliminate vibration noise. It is also stated that where strips are made of translucent or diffusing plastic material the edges of the strips are preferably left unobscured and polished.

Title: Improvements in or relating to subaqueous signalling systems
IPC: G01S1/72
Filed: 1946-12-20
Abstract: 631,601. Subaqueous signalling systems. GENERAL ELECTRIC CO., Ltd., FARREN, L. I., and GRIFFITH, G. W. S. Dec. 20, 1946, No. 37503. [Class 118 (ii)] A subaqueous signalling system comprises means for transmitting pressure wave signals at one or more frequencies, means for receiving the signals adapted to operate one or more relays on receipt of said signals and adapted to discriminate against extraneous noise of the type which contains approximately equal energy throughout the frequency band to which said receiving means is responsive. It is stated that random noise such as is produced by a ship's propeller has a continuous frequency spectrum. The transducer 1 at the receiving end may comprise resonant quartz-steel elements energized through a rubber sheet and feeding an amplifier 2 and limiter 3. The output from the limiter, which is substantially constant for all wanted signals, is fed to a discriminator circuit comprising two resonant circuits 5, 7, and 6, 8, in parallel, tuned to different frequencies f, and f 2 . Rectifier networks comprising elements 9, 10, 11, and 12, 13, 14 are connected respectively across units 5 and 8 and the voltages developed across the resistors and capacitors in response to applied signals are applied to opposite ends of resistor 15, and also to the control grids of valves 20 and 21, whose cathodes are connected together and to the centre tap of resistor 15. In the absence of signals, relays 24 and 25 in the anode circuits of the two valves are unoperated as the permanent bias applied to the valve grids cut off each valve. For noise having equal energy levels at the frequencies of the two tuned circuits f 1  and f 2 , equal voltages are generated across the rectifier circuits and there is no voltage drop across resistor 15. Thus the circuit is not operated by such noise but may however be operated by signals of frequency f 1  or f 2  which cause positive bias to be applied to one or the other of the valves which then passes current causing the corresponding relay to operate. In " mark " and " space " signalling, signals may be sent at frequencies f 1  and f 2 , or the system may be used to control lights fitted to moored floats or buoys. To indicate that the light is actually on, a small transmitter utilizing the receiver transducer may be switched on by relay means in the lamp circuit.
