Title: Ejector-type engine thrust augmentor
IPC: F02K1/36
Filed: 1976-10-05
Abstract: 1527936 Thrust augmentors G P SVISCHEV J G ZHULEV J F POTAPOV V I ILIN R A IZMAILOV A S MEREGA V F SPIVAK V M CHUIKO J V DERGACHEV and A G DVORNIKOV 5 Oct 1976 41342/76 Heading F1J A jet engine thrust augmentor includes a shroud 1 and a nozzle 9 disposed between the engine jet pipe 2 and the shroud, the nozzle having equiangularly spaced, longitudinally-extending slots 12 and serving to transform the cross-section of the jet stream from a circular to a complex shape to increase the surface area of the stream so that it induces a relatively large amount of air to enter the shroud. In Fig. 1 the nozzle is secured to the jet pipe and has stiffening ribs 15, but in Fig. 3 the nozzle is spaced from the jet pipe and secured to the shroud by extensions of the stiffening ribs 17. In each case, the semi-angle # of the nozzle is 8 degrees - 11 degrees, e.g. 9 degrees 20 minutes, and the slots occupy 50% of the surface area of the nozzle. There are typically four slots, and test results show that there are optimum values for the ratios 1/d and h/d.

Title: Poly(hexamethylene terephthalates)
IPC: C09D167/02
Filed: 1965-09-29
Abstract: The invention comprises poly-(hexamethylene terephthalate) having a melt index of 2-15.  The polymer may optionally contain (a) up to 2% by weight (of the total weight of the glycol residues) of an additional glycol (e.g. ethylene-, trimethylene-, tetramethylene-or octamethylene glycol), (b) up to 2% by weight (of the total weight of the acid radicals of an additional dicarboxylic acid (e.g. adipic, sebacic, azelaic or isophthalic acid) or (c) up to 2% by weight (of the total weight of the acid residues) of a tricarboxylic acid (e.g. trimellitic anhydride). Preferably the polyester is made by reacting terephthalic acid and hexamethylene glycol until essentially all of the water of reaction has been removed, then adding an organic liquid, preferably a hydrocarbon, of h.p. 175 DEG  to 265 DEG  C. (which may be solvent or non-solvent for the polyester) and continuing the heating.  When the desired melt index is reached, the polyester may be recovered by first distilling off most of the organic liquid, then adding an aromatic hydrocarbon and allowing the polyester to crystallize out.  If a tricarboxylic acid is used, this is preferably added towards the end of the reaction.ALSO:Paper, cloth, aluminium and steel foil, or nylon, polyethylene terephthalate or regenerated cellulose film may be extrusion coated with poly (hexamethylene terephthalate) having a melt index of 2 to 15.  In an example poly (hexamethylene terephthalate) was extrusion coated on kraft bag paper to form a film of thickness 0.5 to 2 mils.

Title: Improvements in or relating to colour television
IPC: H04N9/87
Filed: 1958-12-22
Abstract: 845,631. Television. TELEFUNKEN G.m.b.H. Dec. 22, 1958 [Jan. 4, 1958], No. 41388/58. Class 40(3). In an arrangement for reproducing colour television signals of the NTSC type from a magnetic record carrier (e.g. a tape) on which such signals are recorded in lines extending transversely of the direction of motion of the tape the signals being "read-off" by means of successive ones of a number of transducer heads mounted on a rotating shaft, the effect of phase shifts in the "read-off" chrominance sub-carrier due to lack of precise alignment of the heads is compensated by deriving the Y, I and Q signals from the composite signals recorded on the tape in an arrangement employing a chrominance sub-carrier oscillator which is synchronized in conventional manner with the recorded colour "burst" signals and phase collected by the first "burst" signal occurring in each line on the tape, the derived Y, I and Q signals then being converted into a composite NTSC colour signal employing a crystal controlled sub-carrier frequency oscillator to which, preferably, the motor driving the transducer head shaft is also synchronized. The invention is described as applied to a system in which a carrier wave frequency modulated by the signals is recorded on the tape. When reproducing such signals the (four) reproducing heads 21 - 24 are successively and cyclically connected to the frequency demodulator 3 under the control of signals derived in circuit 2 from a 480 c.p.s. signal supplied from the motor which drives the reproducing bead shaft and line synchronizing pulses derived in a separator stage 4 supplied from the demodulator 3. The synchronizing pulse output of separator 4 together with the separated video signals are fed to a second separator stage 5 in which the colour "burst" signals are derived and supplied to a phase discriminator 3 which controls the frequency of a chrominance sub-carrier oscillator 8 the phase of which is corrected by means of the first colour "burst" which occurs in each line scanned by the heads 21 - 24 such "bursts" being separated out in circuit 6. The sub-carrier thus stabilized is fed together with the video signal output of stage 4 to a stage 9 from which the Y, I and Q components of the NTSC type colour signal are derived. These components are then fed together with the output of a crystal controlled chrominance sub-carrier frequency oscillator 11 to a stage 12 in which the composite NTSC type signal is produced. The motor driving the reproducing head shaft is preferably controlled by oscillator 11.

Title: Pulse transmission system

Filed: 1964-10-21
Abstract: 1,078,333. Data transmission. WESTERN ELECTRIC CO. Inc. Oct. 21, 1964 [Oct. 24, 1963], No. 42850/64. Heading H4P. In a data transmission system in which each of a plurality of receivers receives data which is asynchronously related to the data for the other receivers, the receivers are enabled in succession and a common delay means is used to develop timing pulses which are related to the data. The embodiment described has 256 data channels in bus 10 which feed receivers 21 and a sampling and storage arrangement (not shown). Clock pulses are fed to each receiver by line 27, and these pulses also feed a counter to deliver a 8-bit count on line 26. The clock speed is sufficiently high that the counter cycles about seven times during each received data bit. Each receiver comprises a gate 90 which responds to one particular count received on line 26 so that the receivers' gates 90 pulse in succession. When a start bit is received from bus 10 on line 91, as soon as gate 90 pulses a pulse passes via gates 97, 96 to line 23 which feeds a tapped delay line common to all the receivers. The pulse also feeds toggle 98 which now inhibits gate 96 and so prevents further pulses from this receiver being fed to the delay line. The taps on the delay provide pulses at times which are multiples of the counter cycle time and which correspond approximately to the centre of each bit. Interleaved with these pulses are pulses resulting from other receivers. The delay's outputs are fed to all the receivers over line 14, the pulses relevant to a particular receiver being selected by gating at 100 with the output of gate 90. The output of gate 100 is used for sampling the received data.

Title: Microprocessor control complex
IPC: H04M3/42
Filed: 1977-10-19
Abstract: A microprocessor control complex for a telecommunications switching system disclosed in the context of a digital time division multiplex switching system. The control complex is arranged as a cluster of hardware identical microprocessors in a distributed processing configuration wherein each microprocessor is provided with its own memory and clock and is programmed to perform a portion of the total function of the switching system. Each microprocessor performs the functions assigned to it independently and asynchronously of the others. Data is transferred between microprocessors in a manner which minimizes the amount of time spent in interprocessor communication. This communication is accomplished via interprocessor buffers which provide dedicated communication channels between partner processors while allowing those processors to continue to operate asynchronously. The distributed control complex allows the software to be modularized with resulting economies in program generation and debugging.
