Patent GB-1055417-A (GB)
Title: Synchronous time interval detector
IPC: G01S13/78
Filed: 1964-10-30
Abstract: 1,055,417. Secondary pulse radar. STANDARD TELEPHONES & CABLES Ltd. Oct. 30, 1964 [Oct. 30, 1963], No. 44313/64. Heading H4D. The invention is concerned with TACAN type D.M.E. transmitter/receivers, wherein only pulses repeatedly synchronous with the interrogation pulses will be accepted as replies for distance measuring purposes. Fig. 1 (not shown) shows on lines A, C, E, and G, synchronous replies 20, to four successive interrogation pulses 10, together with random pulses 30/37 arising from interrogations by other aircraft. Interpretation of the first received pulses 30, as a synchronous reply pulse will produce an incorrect distance measurement. A clock 51 generates pulses at a rate of 1 Mc/s. These are divided down at 52 to produce pulses at a rate of 4000/s. The interrogation pulses 10, occurring at time t 0 , are produced by AND gate 53, on coincidence of the 4000/s pulses with broader pulses produced by generator 50 at 150/s. The interrogation pulse, as well as being transmitted, triggers a bi-stable circuit 56, which is restored to its original state by the first of the received random pulses 30. The output of the circuit 56 is used as a gating signal, feeding the output of clock 51 to a counter 55, which is initially set to zero by the interrogation pulse. The counter 55 thus contains a count representing the time occurring between t 0  and the reception of the first random pulse. The interrogation pulse also starts a counter 70, fed with the output of clock 51, which produces a pulse at time t 300  when a count is reached representing the maximum range 300 miles. The t 300  pulse transfers the count in counter 55 to a blanking gate generator 59, which, at the next transmitted interrogation pulse starts to generate a blanking pulse of duration slightly less than that of the output of circuit 56. The blanking pulse 40 (line B, Fig. 2) is applied to inhibit gate 57, such that the first pulse to pass to the circuit 56 is random pulse 33 (line C). This in turn produces for the next pulse repetition period, a blanking pulse 41 (line D). In the next pulse repetition period however the first pulse to pass to the circuit 56 is the required synchronous pulse 20 (line E). This produces blanking pulse 42 (line F) which again lets through the next synchronous pulse 20 (line G). The count in counter 55 thus represents the required range. The positive blanking pulse P is inverted by 63, such that if the range should exceed 300 miles, the output of invertor 63, applied to gate 58 will be negative when the t 300  pulse is applied to the other control input of the gate. The gate will not operate, such that operation of the system beyond 300 miles is not possible.

Title: Improvements relating to textile materials
IPC: D04H1/42
Filed: 1963-07-06
Abstract: In a sheet material composed of textile filaments, individual filaments are entangled with other filaments in all dimensions of the sheet material to provide a material free from opening and having a tensile strength in all directtions of 0.5 to 15.5 lb./in./oz./yd2 in the absence of adhesives and fusion of the filaments.  The sheet material may be in the form of a non-woven fabric in which the entangled filaments are substantially uniformly distributed throughout or in which the entangled filaments produce linear seams either parallel or extending in two directions.  Such seams may be continuous or dis-continuous, and may be cut out and used to form chenille-type yarn.  Further such seams can be used to unite one or more batts of loose staple fibres or continuous filaments to a crossed-warp of yarns which may be elastic yarns.  The sheet material can be formed of a woven fabric united to a non-woven fibrous sheet by the interentangled filaments or alternatively it may be a woven or knitted structure having individual filaments of its component yarns interentangled with filaments of other yarns throughout the material to provide a fulled or napped appearance and increased covering power.  Such materials are produced by the process disclosed in Specification 1,063,252.

Abstract: 1,134,129. Spray carburetters; regulating. SOC. ANON. ANDRE CITROEN. Oct. 6, 1966 [Oct. 18, 1965], No.44767/66. Heading F1B. In a fuel injection system the pressure drop across an orifice 30 is applied to a piston 7 controlling an orifice 38 in a return flow passage 2, 16, the pressure in which is controlled by a valve 45 actuated by a diaphragm 59 responsive to the suction in a Venturi V in the intake pipe. The pressure in the pipe 16 is transmitted to a piston 7c connected to piston 7 to balance the force due to the pressure drop P 1 -P 2  acting on piston 7. At slow running a valve connected to the throttle linkage closes orifice 30 and diverts the flow through an idling orifice in parallel therewith; a second connection to the throttle linkage also contacts diaphragm 59 to move valve 45 positively to an idling position in which the flow through passage 16 passes through an idling orifice in the valve 45. During over-running the high fuel pressure developed by the pump 1a is transmitted to a shoulder on piston 7 to cause it to open orifice 38 and by-pass most of the fuel back to the pump inlet.
