Title: Monopulse radar system
Inventor: CONNER DR FRANK ROBERT
IPC: G01S13/44
Filed: 1982-11-12
Abstract: This invention is a description of a tracking radar system which uses a frequency-comparison monopulse technique by means of sum and difference frequencies. A Cassegrain antenna is employed and it consists of a parabolic reflector with a five-horn feed A, B, C, D and E. Two different carrier frequencies (fc + f1) and (fc - f2) are transmitted from transmitter Tx via a duplexer 6 and after reflection from a distant target, the signals received are separated by sideband filters 4, 5, 7 and 8. Each FM receiver 12 or 15 extracts a difference frequency signal (f1 - f2) which yields target information in azimuth and elevation respectively, and an AM receiver 14 extracts a sum frequency signal (f1 + f2) for providing AGC bias and an output for range measurement. Tracking errors due to thermal noise and target glint are reduced by employing a wideband FM technique and a ratio detector (Fig. 3, not shown) in each FM receiver. Target tracking in azimuth, elevation and range is achieved by using closed- loop control systems in two orthogonal planes. <IMAGE>

Title: Method and apparatus for grouting between pipes
Inventor: YARNELL IAN ROLAND
IPC: F16L55/165
Filed: 1983-01-12
Abstract: A method of grouting between pipes, for example between an existing sewer pipe and a coaxial inner lining pipe, comprises providing a number of grouting holes in the wall of the inner pipe, fitting valves into the holes, and injecting liquid grouting material through each hole in turn by means of a remotely controlled machine situated inside the inner pipe. Each valve is a two-way valve in that it is shaped to be housed in its respective hole in at least two alternative positions. Initially each valve is fitted in a first venting position so that when grouting material is injected through a neighbouring valve the operator can determine when the intervening annular space between the pipes has been filled by observing the venting of grouting material through the former valve using for example a remotely controlled TV camera. In a second position of the valve, to which it can be pushed by the grouting machine, the valve acts as a non-return valve to prevent the reverse flow of grouting material while it is still liquid. Also disclosed is a device for plugging the annular space at lateral branching locations.

Title: Multi-channel point recorder
Inventor: GAMBIER CHRISTINE
IPC: G01D9/16
Filed: 1984-11-08
Abstract: A multi-channel point recorder has the channels scanned cyclically by a multiplexer 14 and the sensed values are used to control a print head which is displaceable transversely to the direction of movement of a chart. To achieve clear printing, with the printed points being neither too close together when the sensed value is steady nor too widely spaced when the sensed value is changing rapidly, the scan rate is higher than is conventional but not all points are printed. For each channel, the sensed value is compared with the last printed value (subtractor 54, discriminator 62), and the current scan position with the last printed scan position, the last printed value and position being held in a scratch pad memory 56. If the new value or position is further than a distance k from the last printed value or position, it is passed to a buffer 64 for printing, and the new value and scan position are stored in the scratch-pad memory 56. Thus the distance between successive printed points is substantially uniform, with points being printed on only selected scans, at a rate which is directly dependent on the rate at which the sensed value is changing. …<IMAGE>…

Title: A method of depositing an epitaxial silicon layer
Inventor: BURNS GORDON PETER
IPC: C30B25/10
Filed: 1985-09-06
Abstract: An epitaxial silicon layer may be deposited on a monocrystalline silicon substrate by Chemical Vapour Deposition at reduced pressure and low deposition temperature by a method which includes cleaning the substrate within the CVD reactor. The cleaning within the reactor is achieved by applying a heat pulse by heating the substrate to a cleaning temperature of 1000-1250 DEG C for not more than 90 seconds. Deposition of the layer is started by introducing silicon carrier gas not more than 15 seconds before the end of the heat pulse. At the end of the heat pulse the substrate temperature is allowed to fall to a desired deposition temperature between 650 DEG C and 800 DEG C for silane and 800 DEG C and 875 DEG C for trichlorsilane. Preferably radiant heating is used to heat the substrate to the cleaning temperature, and the method may be carried out in an existing radiantly heated CVD reactor. The method allows the deposition of layers of low transition depth (D) shown by SIMS profile (3) of the layer (S-I) and doped substrate. <IMAGE>
