Abstract: 1524633 Radar systems RAYTHEON CO 28 July 1976 [14 Aug 1975] 31506/76 Heading H4D The Doppler frequency of stored timed compressed echo signals in a digital radar receiver is detected by mixing the stored signals with an internally generated frequency swept "chirp" pulse signal and measuring the time of occurrence of an output from a pulse compressor circuit fed with this mixed signal. Received echo signal trains from a conventional coherent radar trans/ceiver 10 are fed separately in phase quarature at the radar p.r.f. f. to their respective stores 26 in time compressor section 24 which stores 64 returns from previous p.r.p.'s in each of 8 analogue (or C.C.D.) delay lines corresponding to 8 range bins. Under control of unit 15, a "chirp" pulse is produced in generator 28 including dispersive surface wave acoustic device 35 and is fed in quadrature to mixers 98 and where it is mixed with the complete contents of one quadrature pair of stores 26 which are read out by respective multiplexer 27 and 29. The readout video signals appear as single sidebands on the chirp pulse. Summer 104 combines the quadrature signals and is connected to pulse compressor 32 which also includes a surface wave acoustic device having appropriate time delay and compressive bandwidth, with respect to the dispersive bandwidth of the chirp pulse. The time delay between the occurrence of chirp pulse trigger P from unit 15 and the occurrence of the compressed pulse at the output of compressor 32 is a measure of the Doppler frequency and may be measured in utilization device 31.

Abstract: 412,836. Cathode-ray tubes. FRIESS AKT.-GES. FUR FILM-UND TONGERATE, 77, Markgrafenstrasse, Berlin. Nov. 13, 1933, No. 31642. Convention date, Nov. 12, 1932. Class 39 (i).] In cathode-ray tube apparatus for recording sound, the emission of electrons from the cathode is controlled by the alternating-current to be recorded, and the cathode stream is influenced by means of a constant magnetic field in such a way that a narrow band of light is created upon the fluorescent screen of the tube. An auxiliary field, which may be a high frequency electrostatic or electromagnetic field or another constant magnetic field, may influence the rays before they reach the main field. As shown, a cathode ray tube 1 has the usual arrangement of the cathode 2 in a Wehnelt cylinder 3, and the anode 4 arranged as usual with an opening 5 for the passage of the rays to the fluorescent screen 6 on the end of the tube. Electromagnets (not shown) are adjustably mounted, near the screen, on a ring 8 which may be rotated around the tube. The permanent field of the magnets constricts the cathode stream so as to produce a narrow ribbon of light on the screen 6. The connections of the cylinder 3 and of the cathode 2 to the output transformer 10 of an amplifier which amplifies the microphone currents are shown. In a modification, an auxiliary controlling electrode, within the Wehnelt cylinder and also connected in the transformer circuit, is provided. There may be a pair of plates, arranged between the anode and the group of magnets, which create an electrostatic field by the application thereto of alternating potentials having a frequency above the audible limit. In place of these plates, electromagnets supplied with high-frequency A.C., or a second group of magnets giving an auxiliary constant field, may be provided.

A frame time base circuit for television apparatus has an output stage connected as an "ultralinear" amplifier. The Figure shows a frame time base comprising an output valve V2 and a second valve V1 cross coupled to form a relaxation oscillator and in which a tap on the output transformer is connected through a resistor to the screen grid so that the valve V2 operates as an "ultralinear" amplifier. The valve V1 generates a sawtooth wave at the grid of V2, the level of the minimum of the wave being maintained constant by discharging the condenser V2 to a point at which V1 "bottoms" and the sawtooth wave is D.C. restored by the grid cathode circuit of valve V2. Resistor VR1 controls the amplitude of the scan, resistor VR2 controls the linearity, resistor VR4 controls the frequency and network N prevents the line scanning frequency from reaching the grid circuit of V1.

Abstract: 1,102,729. Digital electric computer; digital storage device. SPERRY RAND CORPORATION. 28 July, 1965 [10 Aug., 1964], No. 32307/65. Headings G4A and G4C. The invention relates to apparatus to perform a series/parallel conversion, using a memory with the nth bit of N successive word storage locations being successively read out to, or read in from a single bit storage register. A computer operating in parallel mode writes words into and reads words from a store N bits at a time from one storage location at a time. A known programme can be used to cause a x bit word written in memory location N to be written in the 0 bit position of memory locations M + 1 to M + x. Using a  adder to operate on the memory address portion of a read or write instruction the words stored in the locations M + 1 to M+x can be successively read out, each word in parallel, with only the 0 bit position being coupled to the single bit register to produce a serial output to be fed to peripheral equipment. The other bits in the each parallel word are lost. For a SEND mode a REPEAT instruction is required followed by an ENTER CHANNEL 1. The contents of the U register, i.e. the 14-bit instruction being executed, are transferred to the R k  register which thus has the portions of the repeat instructions indicating how many repeats are to be performed. Flip-flops indicate whether the address is to be incremented or decremented. The address in the S register causes transfer of a word from a memory to the Z register. The address in the S register is then transferred to the R register if the address is to be incremented, or the complement of the address is transferred if the address is to be decremented. The number in Rk is decremented. The 0-bit of the Z register is transmitted and synchronous or non-synchronous clock signals are started. The data bit is transferred and a Buffer Request signal is generated which interrupts the processing of the current instruction and the second word is placed in the Z register. This repeats until the number in R k  is zero when the operation is terminated. A similar procedure occurs during the RECEIVE operation.

Thus axial movement of the ring 20 causes simultaneous circumferential movement of the ring. The construction ensures that the axis of the ring 20 remains coincident with that of the turbine should seizure of a vane 13 occur.
