Title: Method and system for electromagnetic detection with correlation
IPC: G01S13/32
Filed: 1972-07-14
Abstract: 1380451 Radar THOMSON-CSF 14 July 1972 [16 July 1971] 33201/72 Heading H4D In order to avoid distortion of the correlation function of a binary code modulated radar due to short range effects, the duration of the binary digits of the correlation reference signal are made shorter than the transmitted code and the reference signal is bipolar. In a C.W. phase modulated radar, the transmitter carrier is modulated in phase according to a pseudorandom code, Figs. 3A-3B. Clock 1, Fig. 5, drives a code generator 2 which feeds the radar transmitter 4. The code passes through a delay 5 of length T 2 , the desired range gating, to AND gate 6 and through inverter 7 to AND gate 8. The clock pulses are also fed through a delay 3 of length T 4  to the AND gates 6, 8. The outputs L, M of the two gates represent the positive and negative pulses in the reference signal. These trains are passed to gates 10, 11 where they are compared to the received signals supplied from radar receiver 9. The correlation is completed by differential amplifier 12 and processor 13 which includes Doppler filtering, detection and integration stages. This method of correlation reduces the variation in the autocorrelation function to a trapezium of amplitude T 3 /T 1  where T 3  is the clock pulse width and T 1  the clock pulse period. Over short ranges for example when used in a proximity fuse, the distortion of the autocorrelation function due to the <SP>1</SP>/d<SP>4</SP> term in the radar equation is greatly reduced (Fig. 1, not shown). Similar results obtain when using a phase modulated pulse radar (Fig. 4, not shown).

Title: Improvements in or relating to mobile models or toys
IPC: A63F9/14
Filed: 1947-12-19
Abstract: 631,155. Mechanical toys. ROSE, G. E., and MECHANEX, Ltd. Dec. 19, 1947, No. 33660. [Classes 132 (ii) and 132 (iii)] A mobile model adapted to 'be set in motion and to have its direction of motion controlled by inclination of a supporting surface comprises a vehicular or animal figure mounted on two or more separately rotatable supporting wheels having a common transverse axis, and, forward of the said axis, one or more freely mounted balls or castoring members running on the supporting surface, the arrangement being such that the model as a whole has a predominance of weight forward of the wheel axis tending to deflect the forward end of the model in the direction of downward tilt of the supporting surface. One or more freely rotatable balls placed forward of the transverse axis may provide the predominance of weight forward ; the figure itself being substantially balanced in a fore-and-aft direction. In one form the model comprises a sheet metal chassis 10 and a body 11 moulded from a synthetic resin. The chassis has a flange 12 along each longitudinal edge and a trough 13 at either end in which the ends of the body are placed and held by tabs 14. There are three openings in the chassis, one 15 near the front and two 16 side by side in the centre. Aligned holes 18 in the flanges 12, 17 receive an axle 21 on which are freely mounted two wheels 22. Four sets of holes are provided to vary the position of the axle. The opening 15 is substantially square and has upwardly and downwardly turned resilient tabs 23, 24 at the sides so as to hold a steel ball 25 freely in position. A brake is provided which is formed by a hairpin-like piece of spring steel wire 26 which slides between the flanges 17 and is retained by the axle 21. The ends 27 of the wire are bent downwardly and outwardly so that, when the wire is pulled back, these engage the wheels. The flange 12 has downward extensions 29 and 30 concealing the wheels and representing wheels in the positions where they would normally be. Thus, when placed on an inclined surface, the model tends to swing so that its long axis is parallel with the direction of greatest slope of the surface and, as the direction of inclination of the surface changes, so the direction of the vehicle changes. In another form shown in Fig. 3, the figure is carved from wood or moulded from plastic and has no separate chassis. It runs on a pair of wheels 32 and two steel balls 35. The figure is substantially balanced about the axle 33 by means of a weight 41, which represents a spare wheel, and is adjusted by a screw. In another form castoring wheels are used instead of balls. The supporting surface may be a tray, held in the hands, or a track or other surface mounted on a stand tiltable in all directions by an electric motor or the like. Otherwise a suitably banked spiral track may be used and this may be suitable for two cars so that they may race According to the Provisional Specification the toy may have more than two balls and a sound producing device.

[Also in Divisions B6, D1 and E1] Ribbed gypsum building board is formed by depositing a slurry 74 between a flat base paper sheet 78 and a pleated paper sheet 18, and expanding the pleats (see Fig. 15, not shown) with gypsum to form the ribs. In the embodiment shown in the Figure, the sheet 18 is pleated by a series of converging, spaced apart, cooperating belts 34 and 36 (see Figs. 2, 6-8, not shown), and applied to the slurry around a grooved roller 62, vacuum manifolds 72 being applied to the grooves as in Fig. 10 (not shown) to suck the pleats into conformity therewith and to fill them with the slurry. Subsequent vacuum manifolds 82, 84, 86 prevent collapse of the just formed ribs. The ribbed sheet then passes along conveyer 118 and the ribs are finally shaped by fixed plates (126) carried by a cross bar (120) (see Fig. 16, not shown), and monitored to a uniform height by rollers 116. The board then passes further along conveyer 118 until the gypsum has set and is cut into lengths by co-operating saw toothed blades (see Figs. 20 and 21, not shown). A reinforcing sheet may be applied adjacent to the pleated sheet in which case penetration of the slurry to the pleats is facilitated by a vibrator 115. The reinforcing sheet may be a fabric or may have apertures to enhance the slurry flow therethrough (see Fig. 28, not shown). In alternative embodiments the grooved roller is replaced by: (a) a curved forming plate having recesses for the vacuum manifolds (Fig. 11, not shown): (b) a smooth roller followed by a grooved roller, the vacuum manifolds being located therebetween (see Fig. 14, not shown): and (c) a series of spaced endless belts passing over two rollers, vacuum nozzles being applied to the rib forming spaces between the belts at the first roller (see Figs. 12 and 13, not shown).
