Title: Improvements in or relating to apparatus for receiving and evaluating combinations of signal impulses
IPC: H04L27/08
Filed: 1956-11-08
Abstract: 830,386. Code telegraphy. SIEMENS & HALSKE A.G. Nov. 8, 1956 [Nov. 9, 1955], No. 34226/56. Class 40 (3). In an arrangement for eliminating or reducing the effect of distortion on the duration of the received elements of a code signal, the operation of the receiving arrangement is made responsive to the variation of the received waveform combined with an oppositely applied waveform constituted by a predetermined phase-shift of the incoming signal or by such a phase-shift plus the subtraction of an amplitude of fixed numerical value from the received signal. The predetermined amplitude may be deducted from the peak portions of the waveform or relative to a fixed zero axis determining the positive and negative portions, and the phase shift should be less than the period of transition of the amplitude of the waveform from the maximum to minimum, and vice versa. In the arrangement shown in Fig. 1, having a receiving relay with oppositely wound windings M1 and M2, the incoming waveform is applied to the winding M1 and also via the delay network LC to the second winding M2 with which is associated a limiting arrangement comprising two rectifiers Rf, resistors R3, R4, R5 and a source P of E.M.F., so that solely the amplitudes of the delayed waveform above and below prescribed numerical values are applied to the second winding M2. In a modification, Fig. 6, the receiving relay M is connected across the output terminals Tu which are connected to opposite arms of a bridge arrangement comprising resistors R6, R7, resistor R1 to which the received waveform is applied and the arm comprising resistor R2, delay circuit LC and biasing arrangement Rf, P for deriving the phase-delayed residual waveform from the input terminals Ti. In a modified bridge arrangement, Fig. 7 (not shown), the delay circuit LC is connected in one arm of the bridge in series with the resistor R1, whilst the amplitude-limiting rectifier network is included in the parallel arm in series with the resistor R2. In this arrangement the numerically varied waveform is in phase with the signal as received and is applied oppositely to the received signal which is subjected solely to the phase displacement operation.

Title: Corpuscular beam microscopes

Abstract: 1525261 Automatic control MAX-PLANCKGES ZUR FÍRDERUNG DER WISSENSCHAFTEN EV GÍTTINGEN 20 Aug 1975 [27 Aug 1974] 34553/75 Heading G3R [Also in Division H1] In a corpuscular beam microscope, the actual image is superimposed on a stored image, and the result is used to adjust the relative positions of the object and/or the image in order to stabilize the image position or focus. In the embodiment shown in Fig. 2a, an image of an object 6 is produced in a plane 10 by an electron microscope 2 including an electron source 3, condenser lenses 4, 5, an objective lens 7, and projection lenses 8, 9. A part 11 of the image is recorded on a photographic plate 12, while another part 15 is detected by a television camera 16 through fibre optics 14, and displayed as an actual image signal 23 on a tube 17. Before the exposure of the plate 12, a reflector 18 is used to direct an image on to a plate 20 which is developed and moved into a plane A' to form a desired or theoretical image 22" on to which the actual image 23 is superimposed during exposure of the plate 12. Correlation between the two images produces a bright spot 24 which is displaced from a central position if the actual image drifts. Any such drift is detected by an array 25 of photo-diodes connected to servo devices 26 which control the excitation of coils 29, 30 to deflect the beam slightly and return the image to its desired position. The correction may also be effected by moving the object 6 using tappets 32-35. A device 36 may be used to increase the contrast of the image portion 15. In another embodiment, the photo-diodes 25 may be replaced by a vidicon tube, Fig. 2e (not shown). Various lens and reflector systems are described for the optical stage 1, Figs. 2b, 2d, 3a (not shown), and the theoretical image may alternatively be stored in terms of phase information rather than amplitude, for example using a photo-thermoplastic layer or electronic light relay tube Figs. 4a, 4b (not shown). The stored image may also take the form of a Fourier-transformed hologram produced by a laser beam, Figs. 5a-5d (not shown). Another laser system is described with reference to Figs. 6a-6b (not shown), and an arrangement for compensating for tilting of the object is mentioned, Fig. 7 (not shown). Defocusing of the image can be detected using circular light-sensitive elements in place of the array 25, and corrections may be made by adjusting the excitation current of the objective lens (7), Fig. 8 (not shown).

Abstract: 845,780. Impregnating for electrical insulation. GENERAL ELECTRIC CO. Ltd. Nov. 7, 1958 [Nov. 7, 1957], No. 34804/57. Drawings to Specification. Class 140. [Also in Group XXXV] A method of encapsulating at least part of an electrical device, e.g. a transformer or a choke, includes the steps of surrounding the said part of the device with a granular absorbent mass of material, allowing the material to absorb a thermosetting (including cold-setting) synthetic resin, which is then liquid, and causing or allow-' ing the resin to set. The device may be mounted within a container which partially encloses it and the absorbent mass of material may fill the voids between the device and the container. The container may comprise a metallic, e.g. brass, framework upon which is wound a tape, e.g. a glass cloth tape, to form the walls of the container. If the device includes a ferro-magnetic core, this core may be spaced from the framework by a shim or shims of resilient material, e.g. rubber. The pressure acting on the absorbent mass of material may be reduced below atmospheric before and during the introduction of the resin, and increased to at least atmospheric and may be higher during at least part of the period when absorption of the resin by the absorbent mass is taking place. The material of the absorbent mass may be an inorganic material, e.g. quartz or silica, in finely-divided form. The resin may be an epoxy resin.

Ammonia, catalytic production of from nitrogen and hydrogen; catalytic apparatus.-The reaction tube for the synthesis of ammonia under conditions of hyperpressure is constructed of an alloy, such as the alloys called ATG and described in Specification 140,508, [Class 82 (i), Metals, Extracting &c.], which is not affected by the gases and can withstand high temperatures and pressures. To remove the heat generated by the reaction, the tube is immersed in a liquid, such as sulphur containing if necessary small quantities of phosphorus pentasulphide or polysulphide, which boils at or near the temperature of the reaction. The liquid S, Fig. 1, in which the tube T is immersed, is contained in the vessel R, the lower part of which is insulated at M. The excess heat of the reaction in the tube T is removed by volatilization of the liquid, which condenses on the upper non-insulated part P of the vessel. The excess heat mav also be removed bv the circulation on the thermo-siphon principle of a liquid which does not boil, e.g. molten lead or tin. The tube T may then be inserted in one leg of the thermo-siphon R, Fig. 3, the other leg being cooled by the pipes S; or the bath R containing the molten metal may be divided into two compartments by the tube of heat-insulating material I, Fig. 4, the outer compartment being cooled by the tubes S. In either case, the bath is provided with electric heating means E, enclosed in heatinsulating material M, for initially raising the temperature of the metal.
