Title: Improvements in or relating to devices comprising aerials for ultra-short waves
IPC: H01Q15/10
Filed: 1953-10-19
Abstract: 741,460. Radiolocation. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Oct. 19, 1953 [Oct. 18, 1952], No. 28859/53. Class 40 (7). A frequency-modulated radar system comprises a transmitter E generating energy frequency-modulated in a saw-tooth law, and having a directional aerial AE fitted with a prism PE of the kind described in Specification 689,408, the receiver R of the system having a similar directional aerial AR and prism PR. The oscillating change of frequency in the generated beam causes the prism to oscillate the direction of the beam through an angle. The receiving aerial AR will only be able to receive a beam of a particular frequency if it returns at approximately the same angle as that at which it was transmitted. Thus in the arrangement shown, with the two aerials aimed in parallel directions, reflections from near objects cannot be received, and the observation of distant objects is thus undisturbed. A motor drive may be provided to oscillate the two aerials through equal and opposite angles, the point of intersection of the directions of the aerials giving the distance of the region that is being searched at a given moment. Signals from the transmitter E and the reflected signals are mixed in receiver R, the beat frequency thus produced indicating the distance of the reflecting body.

Title: Varnish resins based on chlorinated polypropylene or chlorinated copolymers of ethylene and propylene and process for their manufacture
IPC: C08F8/20
Filed: 1959-08-24
Abstract: Chlorinated homopolymers of propylene, and/or copolymers of propylene and ethylene, are made by introducing chlorine into a suspension of the polymers, in a low boiling halogenated hydrocarbon, at a temperature within the range of 40 DEG  to 115 DEG C., and continuing the chlorination until the product contains at least 25% by weight of chlorine.  The halogenated hydrocarbon is generally selected from bromotrichloromethane, tetrachlorethane, fluorochlorethanes, methylene chloride, chloroform, trichlorethane, tetrachloroethylene, and trichlorethylene.  The polymers chlorinated may be subjected to a chlorination treatment, in the absence of an organic dispersing agent, to give a chlorinated product containing at least 20% by weight of chlorine. The chlorination may be accelerated by ultra-violet irradiation, working under superatmospheric pressure, or by using a free-radical substance such as a peroxide.  The chlorinated polymers may be used in the lacquer and varnish industry admixed with conventional stabilizers and fillers.  Specification 799,952 is referred to.

Abstract: 261,802. Klenow, E. W. R. Nov. 23, 1925, [Convention date]. Brakes, electric and magnetic. -, In encased refrigerating machines, particularly such based upon the Audriffen-Singrun principle and comprising a freely mounted part which is subject to a turning moment due to a rotating part but the rotation of which it is desired to prevent such rotation is prevented or restrained by fitting the part with an armature subject to a magnetic field which is stationary or rotates only at a slow speed. The machine shown comprises an evaporator 1 and a casing 2 driven by the shaft 3. The casing 2 encloses a compressor 4 freely mounted on the shaft 3 and in order to prevent or restrain the rotation of the compressor so that the pumping action may he effected, it is provided with an annular iron core 7 secured to a sleeve 5 and arranged coaxially with a second core 8 carried by a support 9 secured to the casing 2. The core 8 is provided with a polyhpase alternating current winding 12 such as to produce a field that rotates at a speed substantially equal and opposite to that of the core and the core 7 may be fitted with a squirrel cage or other short circuit winding 13. The general construction of the braking device is thus similar to that of an asynchronous alternating current induction motor, the stator 8 of which rotates in a direction opposite to that of the rotary field and the rotor 7 of which is stationary or rotates at a slow speed. The field may instead be produced by disposing a magneto outside the rotary casing. According to the Specification as open to inspection under Sect. 91 (3) (a) the braking device may be used in connection with any encased machine having a freely suspended part which is subject to a turning movement. This subjactmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to an electrical butt seam welding process and an apparatus for carrying out said process
IPC: B23K11/087
Filed: 1948-11-16
Abstract: 695,102. Welding by pressure; making tubes &c. WOGERBAUER, A. Nov. 16, 1948 [Dec. 8, 1947], No. 29760/48. Classes 83 (ii) and 83 (iv). In a process for electrically welding the seams of tubes and other articles, the sheet metal parts to be welded are conveyed towards one another at an angle and bent by means of supports until their edges contact, whereby the edges are pressed together, welding current being supplied by means of electrode rollers or inductively and conducted along the separated edges of said parts to their point of contact for the purpose of effecting flash welding. In butt-welding a tube by the process, two semi-circular sections 1, 2, Fig. 2, are led in at an acute angle over guide rollers 3, 4, to electrodes 5, 6. The latter are adjustable on compound slides to enable a position to be obtained where the current flow is directed to give a high concentration at the point 7 where flashing and welding takes place, the electrode rollers pressing the two parts of the tube together. In another embodiment for producing two runs of rectangular-sectioned tubing semi-sections 23, 24 and 25, 26, Fig. 4, are partly formed and guided between rollers 27, 28, and 29, 30, Fig. 5, and then passed at an acute angle to roller electrodes 19, 20 and 21, 22. The spindles 17, 18 of the electrodes form part of the secondary of a transformer, the circuit being completed through the rollers and the work. The primary coils 15, 16 are wound around a core 14 and the bearings 171, 18<SP>1</SP> are insulated from the spindles to prevent current flowing therethrough. The heating may be by means of an induction coil instead of direct contact electrode rollers and the process is described as applied to helically formed tubes and curved tubing. I-section girders may be fabricated by the same process and flat sheets are also butt-welded similarly. Specifications 233,159, [Class 83 (iv)], 377,655 and 510,648 are referred to. As open to inspection under Sect. 91 of the Acts, the Specification describes the use of a die to close up a tube in butt-welding the seam and refers to cutting a plate by reversing the above process. The plate to be cut may have a notch cut in it to obtain the preliminary concentration of current or, pilot pieces may be used for this purpose, the plate being pulled apart as the severing proceeds. Specification 316,964, [Class 83 (ii)], also is referred to.

Abstract: 1305152 Measuring dimension photoelectrically CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 25 June 1971 [26 June 1970] 29967/71 Heading G1A A dimension of an object is measured by forming an image thereof on the sensitive surface(s) of one or more television cameras, and electronically scanning the or each surface, the scanning operation involving line scans substantially parallel to the dimension, and the performance of a left to right scan at speed V 1 , when the time t 1  to scan the line segment between the left-hand end of the scanning line and the left-hand edge of the image, is measured, and the performance of a right to left scan at speed v 2  (which may equal v 1 ) when the time t 2  to scan the line segment between the right-hand end of the scanning line and the right hand edge of the image, is measured. From t 1  and t 2 , the lengths d 1  and d 2  of the respective line segments are calculated and their sum subtracted from the length of a line scan, to give a value proportional to the dimension required.  The scanning operation may be performed by supplying the deflection coils with a sawtooth voltage, when the forward scans are at constant precise speed v 1  and the flyback periods zone v 2 . Alternatively, the coils are supplied so that the return scans are at the same speed as the forward ones. In another arrangement, alternate raster scans are in opposite directions and the scans of the same line from consecutive raster scans are used. Two cameras, whose scans are synchronised but which run oppositely to one another, view the object and corresponding line scans from the cameras are utilised.
