Title: Improvements in/or relating to transmission of electromagnetic wave beams
IPC: H01P3/20
Filed: 1959-11-04
Abstract: 923,202. Waveguides. G. J. E. GOUBAU. Nov. 4, 1959 [Nov. 21, 1958], No. 37418/59. Class 40 (8). [Also in Group XL (c)] Electromagnetic energy is confined to a substantially cylindrical beam by means of phase-correcting plates spaced along the beam. Reflector 21, Fig. 4B, converges slightly radiation from feed 21<SP>1</SP>. Due to diffraction the beam is diverging when it reaches the first of a series of phase-correcting plates 19 which cause it to converge again, the process being repeated at subsequent plates. The feed may be reversed and the reflector replaced by a lens. Reflection at the phase plates is minimized by forming them as a pair of plano-convex lenses back-to-back, or making them of multiple dielectric in annular or shell-like sections or of a plurality of conducting tubes of the order of a wavelength in diameter. Alternatively, they have #/4 dielectric coatings or suitable conductors embedded in them. The beam may be bent through a small angle by a dielectric prism or a large angle by a metal reflector. Waves along path 22, Fig. 5, polarized in the plane of the paper may be transmitted with and independently of perpendicularly polarized waves 23 reflected in direction 22 by grid 24. Beams of different diameters may be coupled by optically imaging the last phase plate of one system into the first of the next. The system may be enclosed in a concrete pipe 31<SP>1</SP> and run underground.

Title: Improvements relating to the preparation or renovation of friction surfaces of synchronising rings
IPC: F16D13/66
Filed: 1959-11-05
Abstract: 886,844. Coating with metals. DAIMLERBENZ A. G. Nov. 5, 1959 [Nov. 13, 1958], No. 37600/59. Class 82(2). [Also in Groups XXIII and XXIV] A method of preparing a friction surface on a non-ferrous synchronizing ring, which may if desired later be sprayed with molybdenum or carborundum and which in use coacts with a synchronizing element of steel in a change-speed gear, comprises compacting and roughening the surface of the ring by blasting with a hard agent having a coarse grain. In the form shown, a friction synchronising cone 12 for use in change-speed gearing is made of a non-ferrous alloy, such as bronze, the surface being either blasted with fine carborundum of grain size 0À5-0À8 mm., or first blasted with a coarse grain agent such as cast-iron balls or pieces of steel and then further blasted with a fine-grain agent. As shown in Fig. 1, the friction surface is provided with a helical thread 13 and cross grooves 15 to remove any oil film when the synchronising clutch is engaged. After blasting with a finegrain carborundum, a compacted surface layer 16, Fig. 2, formed by the impacts of the grains, covers the surface area of the friction cone. Some of the grains of carborundum are embedded within the friction surface, and remain during operation of the friction clutch. As shown in Fig. 3, the helical threads 13, &c. are omitted, and a layer 17 of molybdenum is sprayed on to the compacted surface 16 formed by a previous blasting operation. Reference has been directed by the Comptroller to Specification 816,169.

Filed: 1957-12-03
Abstract: 831,764. Moulding air springs. FIRESTONE TIRE & RUBBER CO. Dec. 3, 1957 [Dec. 6, 1956], No. 37617/57. Class 87(2). [Also in Group XXXII] Bellows 21, Fig. 4, for an air spring, ( B ee Group XXXII), and a member 35 are placed in a mould, Fig. 4. Parts 46, 47, 48 are moved together, Figs. 4-7, to collapse the bellows. At a point in this operation when both small and large beads are forming airtight joints with the appropriate parts of the mould, air or steam under pressure is introduced inside the bellows through passage 74 to prevent folds being formed in the bellows wall. When the mould is fully closed the bellows are vulcanized by steam under pressure. The portion of the bellows near small bead 24 is positively moulded by parts 65, 55 to prevent the formation of wrinkles. When the mould is opened after vulcanization a plunger 50 is held in its lowered position and the bellows adheres to and moves up with the top and intermediate sections of the mould from which it can readily be detached.

Title: Doppler frequency generating oscillatormixer apparatus
IPC: H03B7/08
Filed: 1972-08-14
Abstract: 1400069 Doppler radar JOHNSON SERVICE CO 14 Aug 1972 [16 Aug 1971] 37892/72 Heading H4D An oscillator-mixer apparatus includes a bulk-effect or avalanche diode element mounted in the base of an open-ended transmission cavity which itself is mounted in a microwave cavity housing and forms therwith a coaxial conductor of less than one quarter wavelength; an opening coupled to an antenna for transmitting and receiving microwave energy with respect to the cavity; means for biasing the diode into a portion of its characteristic in which D.C. power is converted to microwave power and an output circuit responsive to Doppler signals generated by the diode mixing transmitted and received signals. Cavity block 7 includes a cavity 8 having an impatt or bulk effect diode 10 mounted adjacent base 9 of the cavity. Conductor 11 forms a coaxial transmission line with the cylindrical cavity walls. Bias to the diode is provided by assembly 17 which screws into the cavity block 7. Dielectric member 17b interposed between the block 7 and bias pin 17a forms an RF by-pass capacitor. Member 16 provides a second by-pass. When the diode is biased to its negative resistance characteristic, microwave oscillations are set up which are coupled to an antenna via impedance transformer 19 havthe a coupling iris 20. The transformer impedance is varied by tuning screw 21. The antenna radiates energy into a protected volume of space and reflected energy is coupled back into cavity 8 where it is mixed with the transmitted signals in diode 10. The Doppler signals are transferred to a bandpass amplifier, Schmitt trigger threshold and an alarm system. Since the maximizing of sensitivity, output power and efficiency are achieved at different bias levels (Fig. 4, not shown), the diode is biased such that the Doppler signal amplitue is sufficeint with low output power. The oscillator may be modulated by coupling a general purpose diode to the open end of the transmission cavity via a coupling loop 33. The diode is connected to a modulating source via a feedthrough capacitor (36, Fig. 6, not shown).

Title: Process for improving the dyeability of stretched fibres and filaments of linear polyalkylene terephthalates
IPC: D06P7/00
Filed: 1965-09-06
Abstract: 1,105,944. Polyester filaments. FARBWERKE HOECHST A..G. 6 Sept., 1965 [17 Sept., 1964], No.37948/65. Heading B5B. In a process for improving the dyeability of previously stretched filaments or cables of filaments of linear polyalkylene terephthalates by heat treatment, the previously stretched filament or cable of filaments is heated by means of a jet of gas having a temperature within the range of 180‹ C. to 280‹ C. and which meets the filament or cable of filaments at a speed within the range of 2  to 40 metres per second, and the filament or cable of filaments is then cooled to a temperature below the second order transition temperature. Polyalkylene terephthalates are defined as polyesters of terephthalic acid and a glycol containing 2 to 18 carbon atoms, especially ethylene glycol. Cooling is preferably brought about in a cooling bath or a violently agitated gaseous medium, for example, air. Preferably the filament or/cable of filaments consists of polyethylene terephthalate, and the jet of heated gas consists of air or nitrogen. The time of residence of the filament or cable of filaments is desirably less than one second, and the filament or cable of filaments may shrink to a degree of 10% to 30% during the heat treatment. The process may be improved by preheating the filament or cable of filaments to 100‹ to 170‹ C., and by effecting the preceding stretching treatment at 50-100‹ C., using a low stretching ratio.

In the illustrated embodiment the wheel washing brushes 19 are mounted on arms 21 pivoted to the sides of the structure 1 downstream of the pivots 10, each arm 21 being biased to swing in a direction opposite to that in which the adjacent arm 9 is biased to swing. The biasing force on the arms 9 is greater than that on the arms 21 and hence the arms 21 are held in the rest position illustrated in Fig. 1 by contact of abutments 23 on the arms 9 with the arms 21. In use, the arms 9 will be moved from their rest positions by advance of a vehicle V through the tunnel structure 1 such that the brushes 7 clean the central area A of front of the vehicle V, first from outside to inside of the area and then from inside to outside, Fig. 3, and then the remainder of the front and sides of the vehicle. The arms 21 cannot swing to allow the brushes 19 to clean the vehicle wheels until the arms 9 have been moved from their rest position releasing the abutments 23 from the arms 21. The brushes 7 are mounted on the arms 9 so as to be capable of tilting about a horizontal axis if necessary, and rollers (17) (Fig. 4) are provided on the shafts of the brushes 7 which, when the brushes are tilted, engage guides 18 on the tunnel structure to guide the movement of the arms 9 as a vehicle passes through the tunnel structure.

Abstract: 830,667. Interrupters. SQUARE D CO. Dec. 13, 1956 [Feb. 27, 1956], No. 38078/56. Class 38 (5). A control device for the sequential operation of switches comprises actuating means operating the switches and driven by a rotary drive, the actuating means being interlocked. Two discs 21, 22 are frictionally carried by a sleeve 19 on a shaft 15 driven by a synchronous motor 2. The disc 21 has projections 72, 73, 74 on one face and a projection 71 on the other, whilst disc 22 has projections 82, 83, 84 on one face, and 81 on the other. The disc 21 has arcuate slots 75, 76, 77 through which the projections on disc 22 may extend and the discs may be arranged with their three projections pointing to the left, as in Fig. 2, or to the right (not shown). The projections co-operate with rubber-covered pins 43, 63 on arms 42, 62 pivoted at 28, 48 and having members 33, 53 engaging the operating pins 39, 59 of snapaction switches 13, 14. As the discs 21, 22 rotate, the switches are therefore alternately moved on and off, the pins 43, 63 being interconnected by an apertured plate 46 which prevents both switches from being in the same condition at the same time. Due to their frictional drive, the discs 21, 22 can be adjusted relatively to each other.
