Patent GB-1362343-A (GB)
Title: Vehicle-position-determining systems
IPC: G01S5/06
Filed: 1972-07-14
Abstract: 1362343 Radio position-finding SIEMENS AG 14 July 1972 [28 July 1971] 32976/72 Heading H4D A surface vehicle to be located transmits a radio signal which is received by at least three receiver stations which transmit the signals over fixed links to a central station whereat the phase difference between signals received at two stations is determined and by using two or more independent difference determinations the vehicle position is located and errors occurring in the system are compensated by independently determined corrective values derived from signals from a reference transmitter at a known location. Fig. 3 shows the basic principle of the system wherein a central control station Z radiates a UHF signal coded by coding device COD to call either individual vehicles or a group of vehicles each of which then replies in a specified order. The vehicle mounted receivers FZ1, 2 ... n, reply with a 3 KHz modulation of the UHF carrier. Fixed receiving stations El, E2, E3 receive these signals and demodulate using afc to provide measuring signals which are relayed over low frequency cables l1, l2, l3 to the control station Z. Here, comparators K1-K3 detect zero crossings and the received signal actuates pulse shaper ST which enables counters Z1, Z2, Z3 which commence counting pulses from generator ZTG. The counters are disabled by the first zero-crossing occurring on each input and subsequently difference units S12, S13, S23 form measures of the phase differences between the signals received at the three stations. The differences form intersecting isachrones which are combined in display AG to show the position of the vehicle along with an identifying number N on a television map or by light projection on a screen. The complete system at the control station is shown in Fig. 5, which includes error correcting circuitry. Further each delay to the different receiving stations is measured several times in counters Z11, Z12, Z10 and then averaged in device MW or the lowest value selected by selector KW the choice being by switch U operated arbitrarily. In order to correct for errors in the receivers and relay links, from time-to-time transmitter ZS calls a reference transmitter MSZ identical to the vehicle transmitters but in a known position, i.e. the control station. When this is done switch SV2 is changed over such that the delay times are applied to subtractor SUB which compares them with the known correct values. These are stored in memory KOR and added to subsequent measurements of delays from vehicle transmitters in adders ADD 1 &c. The outputs from counters Z10-Z12 are compared in comparator VE such that if the results are substantially equal, that transmitter must be at rest and therefore switch A is operated and the transmitter is ignored until it begins to move once more.

Title: Improved process for making powdered metals
IPC: B22F9/00
Filed: 1948-12-23
Abstract: Metal powder used in the production of metal articles by compression and sintering is produced by successively grinding the metal chips resulting from the machining of metal parts to dust of fineness less than 0.2 mm., reducing the dust at temperatures not exceeding 1920 DEG F. by means of hydrogen, producer or town gas or solid reducing agents, and grinding and sifting the reduced product.  The metal chips are cleaned and sorted prior to grinding and may be rendered hard and brittle if necessary by heat-treatment such as heating in cyanide containing salt baths and quenching.  Prior to or after reduction the powder may be subjected to a purification treatment such as magnetic separation, cyclone sifting or chemical treatment. Ball, vibratory and air-jet mills are suitable for the grinding operations the ratio between chips and grinding bodies being given for ball mills as 1:2.  In an example an alloy powder containing 0.82 per cent C.; 3.56 per cent Cr; 9.22 per cent Mo; 1.85 per cent W; 1.2 per cent V; remainder Fe is produced.  The treatment of a steel containing 0.15 per cent C; 4.5 per cent Ni and 1.2 per cent Cr is also mentioned.  Specification 527,430 is referred to.

Title: Aircraft jet propulsion power plant

Abstract: 1,047,990. Jet propulsion engines. DORNIERWERKE G.m.b.H. Aug. 9, 1965 [Aug. 8, 1964], No. 34027/65. Heading F1J. [Also in Division B7] An aircraft power plant comprises at least two jet engines and a ducted fan disposed at the rear of the aircraft fuselage, and fan having tip turbine blades disposed at its periphery, the jet engines being disposed substantially outside the casing of the fan, and the inlet nozzle segments of the tip turbine communicate with the jet engines through gas ducts. The power plant shown in Fig. 1 comprises a pair of jet engines 2 mounted one at each side of the aircraft fuselage 1, also a ducted fan comprising fan blades 3 and tip turbine blades 4 which is disposed within a duct 5. A pair of gas ducts 8 extend between the jet engines 2 and the tip turbine inlet nozzle segments, the walls of the gas ducts having flaps 9 which may be moved from the position shown in full lines to that shown in chain-dotted lines. The gas ducts 8 also contain flap members 10 which are pivotally mounted at 11 for movement between the position shown in full lines and that in chain-dotted lines. When the ducted fan is to be utilized for propulsion the flaps 9 and the flaps 10 are moved to the positions shown in full lines so that the gases from the jet engines 2 pass through the ducts 8 to drive the tip turbine 4 and so the fan 3. When the jet engines alone are to be utilized for propulsion, the flaps 9 also the flaps 10 are moved to the position shown in chaindotted lines so that the gases issuing from the jet engine nozzles 7 pass direct to atmosphere, the ducted fan being inoperative. A thrust reversing device comprising a plurality of pivotally mounted flaps 15 is disposed downstream of the ducted fan outlet. In a second embodiment Fig. 2 not shown, the flap member 16 associated with the opening in the wall downstream of the jet engine nozzle has two ranges of movement, the first being pivotal movement about the point 17 to the position shown in chain-dotted lines in which the jet engine gases pass direct to atmosphere (the flap member 28 being in the position indicated in chain-dotted lines closing duct 8), the second range of movement of the flap member 16 being about the pivot point 18 to the position shown in broken lines in which the jet engine efflux is diverted laterally or forwardly for braking purposes. In Fig. 3, not shown, the flap 25 is pivotally mounted on the wall at its downstream end, the flap in the full line position closing off the opening in the wall so that the jet engine gases pass to the tip turbine 4, the flap in the broken line position allowing the jet engine gases to pass direct to atmosphere for jet thrust, while the flap in the chain-dotted line position deflects the jet engine gases forwardly for braking purposes. A pivotally mounted flap member 23 is disposed in the engine jet pipe.
