Title: Improvements in and relating to devices for guiding energy-conveying leads
IPC: B66C13/12
Filed: 1963-08-01
Abstract: 991,227. Taking up slack in flexible connectors. KABELSCHLEPP G.m.b.H. Aug. 1, 1963 [Sept. 4, 1962], No. 30510/63. Heading B8B. In apparatus for guiding looped flexible cables, conduits &c. between a fixed point and a movable device, a supporting carriage has a self-contained drive controlled by the movements of the movable device. In one example, the cables 2, Fig. 1, are looped over and supported by rollers 5 of an elongated carriage 7 which is driven by a variable speed electric motor 16 through a rack-and-pinion device 18, 19. The motor 16 is controlled by a servoswitch 12 mounted on a small intermediate carriage 8 and having an operating arm 13 actuated through a fork 15 on the movable device 11. The cables 2 are connected to the movable device 11 through cable chains 9, 10, permitting the limited lost-motion required to actuate the switch 12. In modifications the cables 61, Fig. 5, are supported by a looped cable chain 62 having runners 64 engaged with guide rails 65 of a movable frame 66. The guide chain and frame assembly carries a rack 79 which may be engaged by a stationary driving pinion as in the example of Fig. 1, or as shown in Fig. 5 by a pinion 78 on a carriage 69 forming one of the links of the chain and carrying a motor 77 controlled from a servo-switch 70 on the carriage 69. In further modifications the rack-and-pinion devices may be replaced by drum-driven cables and the carriage may be driven by a motor electrically synchronized with the main drive motor. A method of controlling movements by a series of spaced electrical contacts along the tracks of the movable devices is also referred to.

IPC: D06M13/256
Filed: 1964-08-04
Abstract: Textile materials containing keratin fibres, e.g. woven and knitted fabrics comprising wool alone or in admixture with nylon fibres, are rendered crease-resistant and/or permanentaly folded or pleated by impregnating them with a solution of a salt of methylolsulphonic acid HO.CH2.SO3 Me where Me is a metallic ion, and then maintaining them in the desired shape for 3-20 minutes under pressure at 60 DEG -110 DEG C.  The treating solution may also contain an anionic or non-ionic dispersing agent.  After impregnation the material may be dried at a temperature below 100 DEG C. and the thus presensitized material subsequently set in the desired shape after moistening with steam or pressing.

Relates to a pulse radar with a conical scan aerial the axis of which is automatically directed at a target by means of azimuth and elevation servos controlled by misalignment error signals, and utilized in an arrangement for measuring the miss distances of missiles aimed at a moving target. According to the present invention the radar receiver is provided with two auxiliary channels each having a range gate and wherein these range gates are at predetermined ranges relative to the target-tracking range gate. In the embodiment the range gates F 1 , F 2  corresponding to planes F1, F2 produces missile error azimuth and elevation signals #α 1 , ## 1  and #α 2 , ## 2 , respectively to produce successive marks E1, E2 on an azimuth-error/elevation-error cathode-ray (CR) tube display of the long-persistence kind via switches Cα, C#; the missile error in target plane FO is then estimated by interpolation. Detectors Q 1 , Q 2  furnish output voltage values of 1 or 0 in the presence or absence respectively of an echo signal at the outputs of the corresponding channels F 1 , F 2 ; these voltages are fed to a comparator circuit T having output terminals a 1 , a 2 , a 3  to furnish output voltages U 1 , U 2 , U 0  for controlling switches Cα, C#, and the CR beam in the following manner: Detector Q 1  output 0 1 0 " Q 2  " 0 0 1 " U 1  " 0 non- 0 zero U 2  0 0 non- zero Uo Non-zero, to 0 0 reduce C.R. beam intensity to zero The cathode-ray tube display may be photographed. The auxiliary receiver channels may both correspond to ranges on the same side of the target plane and the miss distance is then derived by extrapolation.

Abstract: 776,129. Optional signalling systems. TOUVET, G. Nov. 2, 1955, No. 31292/55. Class 40(3). In a secret signalling system using optical radiation the intensity of the optical radiation is modulated in accordance with the intelligence to be transmitted, the overall amplitude of the intensity being kept constant. As shown (Fig. 4), radiation from a source 8 of constant intensity such as a filament lamp or an arc is focused by a lens 9 on an electro-optical modulating device 10 such as a Kerr cell in which the intensity of the light source is modulated. The modulating device is controlled by the output of an oscillator 14 modulated at 13 with the intelligence to be transmitted. The modulation may comprise (a) two components of different frequencies whose amplitudes are complementarily modulated so that the amplitude of one increases as the other decreases; (b) a single frequency modulated component the amplitude of the frequency modulated carrier being maintained constant; (c) a single-phase modulated component; or (d) a frequency shift telegraph system in which an oscillator is keyed between two alternative frequencies one of which represents marks and the other spaces. The effective strength of the source is kept constant while the frequency changes. In the arrangement of Fig. 5 (not shown), two different light sources are used the modulation being of the kind referred to at (a) and (c) above. In the arrangement of Figs. 1 and 2 (not shown), the intensity of the source itself is modulated. Specification 774,471 is referred to.

Abstract: 659,820. Velocity-modulated tubes. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 28, 1947, No. 31558. Convention date, June 22, 1945. [Class 39 (i)] In a reflex velocity-modulated tube the cavity resonator 32 is supported within a cylindrical aperture of the anode block 29, and is coupled through a narrow slot 57 with a transverse slot 56 forming a rectangular waveguide. Opposite the mouth of the wave-guide is a vitreous window 62 supported through a thimble 61 in an opening of the envelope. A groove 66 surrounding the mouth of the waveguide 56 forms a half-wave choke, and a corresponding half-wave choke 67 is provided outside the window 62. The anode block 29 rests on a dielectric disc 24 supported by a metallic ring 25 secured to a corrugated heatconductive member 28. The corrugated member 28 is provided with a longitudinal slot so as to lock with the thimble 61. The cavity resonator 32 comprises a cylindrical member 33, a conical member 34, and a flexible diaphragm 35. The diaphragm 35 and a flange 41 on the member 33 form a radial half-wavelength short-circuited transmission line. Tuning is effected by moving the flexible diaphragm 35 by micrometer head 81 acting through rod 78, cross-piece 48 and cylinder 46. A fine tuning adjustment is obtained by varying the voltages of the various electrodes. The reflector electrode 44 is supported by a dielectric cylinder 45 secured within the cylinder 46. The indirectlyheated cathode 12 is mounted on an insulating disc 19 which abuts the shoulder 18 of a focusing cylinder 16 so that both cathode and focusing cylinder are retained within a metallic thimble 17.
