Title: Improvements in or relating to systems for determining the positions of aircraft
IPC: G01S1/02
Filed: 1957-06-27
Abstract: 890,498. Radio navigation. GENERAL ELECTRIC CO. Ltd., and KIRKNESS, R. H. June 18, 1958 [June 27, 1957], No. 20399/57. Drawings to Specification. Class 40(7). In an aircraft position finding system pulse signals emitted from the aircraft in response to a signal from a ground station are detected by at least three spaced ground receiving stations and the times at which the aircraft signal arrives at the receiving stations define three hyperbolae whose common point of intersection indicates the position of the aircraft. A digital computer correlates the arrival times and radio or other links transfer information from the receiving stations to the computer. Many aircraft may be detected using this system, thus a first aircraft may respond to the transmitted or master pulse after a delay t1, a second aircraft after a delay t1 + t2, a third after t1 +2t2, &c. Alternatively the ground transmitter may emit a series of pulses between the master pulses and the aircraft transponders are then arranged to count a certain number of pulses after each master pulse before transmitting. The transponder pulse may contain information of use to the airport controller. The compueter may be arranged to switch to elliptic position finding, when the range of an aircraft exceeds a certain value (see Specification 890,497). Aircraft coming within the useful range of the apparatus may lock on to the system by being allocated a position in time between the master pulses at which to respond, this lock on may be made manually on direction by the controller or may occur automatically by the transmission of an allocating pulse.
Patent GB-984100-A (GB)
Title: A new method of manufacturing acrylamide
IPC: C07C233/09
Filed: 1963-05-22
Abstract: Acylamide is made by sulphuric acid hydrolysis of acrylonitrile, in the presence of at least one part by weight and preferably between 6 and 12 parts for one part by weight of acrylonitrile, of a solvent which is non-miscible with water, which does not dissolve acrylamide at ordinary temperatures but does dissolve it when hot, particularly benzene and methyl substituted homologues i.e. toluene, neutralizing with a base particularly calcium carbonate, separating the sulphuric acid in the form of a sparingly soluble sulphate (CaSO4), heating during or after the neutralization to a temperature sufficient for effecting an extraction of acrylamide by means of said solvent, cooling the solvent and separating out the acrylamide crystals.  The solvent may be added to one or several reactants during the various stages and may be recovered and recycled.  In a modified process, addition of the solvent may take place after hydrolysis but before neutralization.  It is preferred to include a polymerization inhibitor e.g. a copper salt in the reaction medium. The chemical reactions can be performed in the presence of one solvent and the extractions by means of another. In the examples benzene and toluene are utilized.

Title: Improvements in and apparatus for the operation of direct current electric arcs
IPC: H02M7/15
Filed: 1932-07-20
Abstract: 418,971. Converting. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.-(I. G. Farbenindustrie Akt.-Ges. ; Frankfort-on-Main, Germany.) July 20, 1932, No. 20510. [Class 38 (ii).] A D.C. electric arc burning in an atmosphere of hydrocarbons is stabilized by means of a grid controlled rectifier which supplies the arc from an A.C. circuit, the grids potential being influenced in dependence on the arc current, the arrangement being such as to give a falling potential characteristic. In one form the grid potential consists of a variable D.C. bias superimposed on an alternating potential, the D.C. bias being controlled by means of a valve, the grid of which is controlled in dependence on the arc voltage. In another form shown in Fig. 3, the grids are controlled by a momentarily applied positive impulse, the moment of application being determined by a valve 8 under the control of a photo-electric cell 15. Fig. 4 shows the photo-electric cell arrangement. A source of light 2 is rotated synchronously with the supply by a motor 1 and the beam is reflected by a conical mirror 3 onto the photoelectric cells 5 which are screened by a slotted disc 4. The slots in the disc are arranged so that the cells are energized in succession. The position of the disc will determine the moment of illumination of a cell and therefore the moment of energization of the corresponding grid. The position of the disc is determined by the arc current. In a further modification the grids are controlled by a momentarily applied high frequency potential, the moment of application being determined by a valve under the control of a photo-electric cell. In a further modification for supplying two arcs the supply transformer has two separate secondaries which are connected to groups of anodes in the rectifier, these groups being provided with separate grid control.

Abstract: 1386699 Non-woven fabric HOECHST A G 3 May 1972 [5 May 1971] 20612/72 Headings D1R and D2B A non-woven fabric is impregnated with a liquid containing an elastomeric binder and substance(s) which lower(s) the temperature at which the binder coagulates, and is contacted on one side with a liquid at a temperature sufficiently high to effect coagulation of the binder whilst the other side of the fabric is maintained at a temperature below that at which the binder coagulates from the liquid. Test fabrics split in half contained 65% to 80% of the binder in the half having the hot liquid treated side. The fabric may be a needled web of carded, air laid or wet laid polyester and/or polyamide fibres or filaments. The binder comprises an aqueous dispersion of natural or synethetic rubber (e.g. butodiene-acrylonitrile), polyurethane or poly (meth-) acrylic ester. A polysiloxane is added to reduce the coagulation temperature to 20 to 90C, preferably 30 to 50C. The binder dispersion is applied by immersing the web in a bath and calandering to remove excess liquid. The hot liquid is polyglycol 400, a higher alcohol or a polyalcohol, and is at 35 to 140C, preferably 70 to 100C. The other surface is maintained at 5 to 40C. Preferably the web is passed around the surface of a cooled roller, one quarter of the surface of which is immersed over its whole length in a tank of the hot liquid. After leaving the coagulating apparatus the web is washed with water and then dried. The binder comprises 40 to 50% of the total weight of the fabric.

Filed: 1937-07-26
Abstract: 499,664. Liquid-blast switches. UPTON, A., PAILIN, G., and FERGUSON PAILIN, Ltd. July 26, 1937, No. 20636. [Class 38 (v)] A circuit-breaker having arc control by means of cross-jet type explosion pots has a tubular moving contact rod which is provided remote from its contacting end and outside the main passage, with one or more valved ports arranged to open, such as against the bias of a spring, when and only when, due to interrupting unduly large powers, the arcpressure generated in the pot is greater than arises when interrupting powers for which the arc control means is otherwise ordinarily designed. The valve may be arranged to open quickly initially and then against, for example, a dashpot. The fixed contact 1 is slidable in a metal tube 6 screwed into a metal drum 5 closing the end of the explosion pot 4. The explosion chamber 3 communicates through passage 12 with a transverse passage 13, which provides the cross-jet of oil or other liquid and is fitted with arc splitters 14. The hollow movable contact 2 screws into a tubular member 16 having one or more radial ports 17, and a piston 19 having a stop (not shown) at its left-hand end, is normally urged by a spring 21 into a position in which the ports are closed, the piston being operable by excessive pressure when large powers are being opened. Alternatively a hinged-plate or clappertype valve may be employed on the cylindrical exterior or extreme end of the movable contact, or on its supporting bar, and closure of the valve may be controlled by a dash-pot.

Title: Cue Signal Communication System
IPC: G08C19/18
Filed: 1967-05-04
Abstract: 1,152,397. Selective signalling. KOKUSAI DENKI K.K. 4 May, 1967 [24 Aug., 1966], No. 20786/67. Heading G4H. [Also in Division H4] In a method of signalling, e.g. for the transmission of core signals to control the operation of a reproducer, a single tone is transmitted whose frequency is varied cyclically in a sawtooth manner over a predetermined frequency range and at the receiver a band-pass filter is provided, whose frequency pass band is smaller than the range of frequencies over which the transmitted tone is swept so that the output of the filter comprises a pulse each time the transmitted frequency sweeps across the pass band. The number of sweeps of the transmitted frequency is controlled to represent the information transmitted and a number of tone signals may be transmitted selectively to convey information. Fig. 6 shows a system for transmitting cue signals to control the reproduction of programme material in the receiver of Fig. 7. In Fig. 6, a wobbling device 1 generates a saw-tooth wave of period about 1 c.p.s. which frequency modulates an oscillator of centre frequency 1900 c.p.s. and produces a deviation of 5 c.p.s. The oscillator output is fed to a mixing circuit 11 where it is combined with a programme signal applied to terminal 8, a band elimination filter 9 being switchable into the channel from terminal 8 when the signalling from oscillator 2 is actuated so as to remove programme signals from the region of the frequency modulated signal. The output from the mixer 11 is fed to the transmission medium via, for example, a radio frequency modulator, for either FM or AM. At the receiver, Fig. 7, the received signal is demodulated and the programme signals fed to the audio amplifier either continuously via switch 15, or only on detection of a cue signal by the narrow pass band filter 5 and appropriate actuation of the counter 6a and consequent operation of switch 16. In the automatic operation the counter 6b may be arranged to operate on the subsequent reception of a cue signal to disconnect the programme from amplifier 19. A system is also described with respect to Figs. 8 and 9 (not shown) for generating a number of wobbled signalling tones and connecting the detectors of those tones at the receiver to a logic circuit to detect various signalling conditions.

Abstract: 1506632 Protecting sectionalized distribution networks SPRECHER & SCHUH AG 19 May 1975 [22 May 1974] 21235/75 Heading H2K In a sectionalized intermeshed distribution network fed from several points A, B, C through main circuit breakers 1, 8, 12, time-delay circuit breakers 2-7, 9-11 are provided at the beginning and end of each section a-f. On occurrence of a fault first all the main circuit breakers are tripped. They are then reclosed in succession, and as each one is reclosed, only those section circuit breakers at the beginning of a section, as viewed from the main breaker being closed, are rendered operable (i.e. capable of tripping), and the time delays of the operable breakers are staggered so that those nearest the relevant main breaker have the longest delay. In this way the breaker at one end of the faulty section will be tripped when one of the main breakers is reclosed and the breaker at the other end will be tripped when another of the main breakers is reclosed, whilst the remaining sections will have their supply restored. A section circuit breaker may need to be rendered operable for the reclosure of more than one main circuit breaker, but it is shown that for the network of Fig. 1 any given section breaker requires the same time delay whenever it is operable and that each has to be rendered inoperable (or alternatively, operable) for only a single period following the original occurrence of the fault. This can be achieved by a timing circuit associated with each section breaker.
