[Also in Divisions H3-H5 A photo-electric measuring apparatus for determining the optical transmittivity of an extended optical medium e.g. cloud 6, Fig.1 comprises a pulsed laser 1 transmitting coherent light pulses to the medium, a receiver 2, receiving, coaxially with the transmitted pulses, the reflections from the extended medium and comprising a photo-multiplier 12, and a circuit, Fig.5, for processing the echo signal PE Fig.4, from one pulse, signal PE showing discontinuities at times t 1  and t 2  indicating reflections at the boundaries of area of the medium having different optical characteristics. The received echo signal amplitude PE is given by:- where:- P s  = transmitted pulse amplitude #v= volume element of medium reflecting echo signal (dependent on transmitted pulse width and beam width) X =ct = distance to volume element #v. # (x) = remitting co-efficient of medium # (x) = extinction co-efficient For an area having constant values of #(x) and #(x) PE.t<SP>2</SP> is exponential e.g. Fig.3 and:- In the processing circuit, a differentiator/computer amplifier 21 determines dPE/dt and detects any discontinuities in the echo signal from amplifier 20. A logarithmic amplifier 22 determines Log |PE/P s  t<SP>2</SP>| if means 21 detects no discontinuities. A differentiator 25 then produces the value of #(x). A computer 26 determines the visibility of the medium from the equation: and passes it to the recorder or display 28. If means 21 detects discontinuities a counter 23 is activated to determine times t 1 , t 2  &c. A logarithmic amplifier 24, similar to 22 processes the echo signal PE but is gated off during the discontinuities by the counter output. Successive values of [C-D#(x).t] are thus produced by amplifier 24 and the value of (X) for each area is detected by differentiator 27 and displayed or recorded at 28. Where the discontinuities are due to a cloud, a cloud thickness indicator 29 is provided fed by counter 23.

Title: Antenna system
IPC: H01Q9/32
Filed: 1946-11-22
Abstract: 640,152. Radio aerials. BENDIX AVIATION CORPORATION. Nov. 22, 1946, No. 34746. Convention date, Jan. 2. [Class 40 (vii)] An antenna system comprises means forming a ground plane, a horizontally extending, circular, plane member spaced less than a quarter wavelength from said ground plane at the mean frequency of the system, and a co-axial uniform cylindrical member between the plane and the circular member which is electrically interrupted at a point spaced from the circular member and fed at the interruption, which is so positioned that the input impedance of the antenna matches the characteristic impedance of the line. The antenna is of particular value where the height is limited to less than a quarter of the operating wavelength by space considerations as, for example, in vehicle mounted equipment and it may also be used over a broad frequency band without undue difficulties in matching. In one embodiment, Fig. 3, the ground plane 10 may be a large conductive sheet or a plate of quarter wavelength radius at the mean operating frequency. A composite hollow cylinder composed of conducting segments 11 and 28 separated by a short insulating section 12 is mounted over an aperture in the ground plane and is energized by a co-axial feeder passing therethrough. The length of the composite cylinder is considerably less than a quarter wavelength. Disc 14 is mounted on top of element 28, its radius being such that together with the length of the composite cylinder a quarter wavelength antenna is formed. The position of the segment 12 at which point the antenna is energized depends on the matching impedance required. If the height of the antenna is still further reduced so that the load presented to the feed line 15 is capacitive a shorted stub may be connected across the feed points to provide an inductive reactance to counterbalance the capacitive reactance of the system. The Specification as open to inspection under Sect. 91 comprises also an embodiment (Fig. 4, (Cancelled), not shown), in which segment 28 is omitted and insulating segment 12 is in contact with disc 14. Fig. 5, (Cancelled) (not shown), shows the arrangement of a compensating shorting stub under such circumstances. This subject-matter does not appear in the Specification as accepted.

Abstract: 971,803. Laying railway tracks. F. PLASSER, [trading as FRANZ PLASSER BAHNBAUMASCHINEN]. Sept. 28, 1961 [Dec. 15, 1960; May 18, 1961], No. 34918/61. Heading E1G. Apparatus for laying and/or taking up tracks of permanent way comprises grippers 6, spaced from the end 1 of a wagon, which is used for transporting rails 2 and sleepers 3, the grippers being operable to hold the rails 2 at a specific height, and means arranged between the grippers 6 and the end 1 of the wagon for rotating the sleepers 3 individually in a horizontal plane to position them under the rails 2. Two grippers 6, one for each rail 2, are each held at the end of a cantilever arm 5, both arms 5 being rotatable on a common mounting 5<SP>1</SP>. In laying a track the wagon runs on the rails which have already been laid, and further rails 2 are carried on mountings at the sides of the wagon, from which they are unloaded on to the track bed e.g. by means of a winch (not shown) and a rope 12. The rails are then engaged by the grippers 6 and held above the rail bed. Sleepers 3 are conveyed by a lifting means 4, running on a guideway 4<SP>1</SP>, to a roller conveyer 11 which conveys the sleepers on to the track bed into a position in which the sleepers lie longitudinally of the track. The conveyer 11 is situated between one rail and the central axis of the track, and it deposits the sleepers in the middle of the track. The sleepers 3 are engaged individually by grippers 10 which rotate each sleeper through 90 degrees and which deposit the sleepers at their correct spacing under the rails, which spacing may be set by means of an abutment (not shown). The grippers 10 are mounted on an articulated joint 9 on a mobile carriage 8, which runs on a guideway 7. The mounting 5<SP>1</SP> may be locked in any desired position, e.g. by means of a toothed rim on the periphery of the mounting 5<SP>1</SP> and an associated pinion, so that the grippers 6 may hold the rails 2 in any desired curvature, and screw-driving machines may be provided to directly fix the rails 2 to the sleepers 3. Each gripper 6 is provided with rollers or cylinders to permit longitudinal movement of the gripper relative to the engaged rail 2 without releasing the rail, and the grippers 6 may be vertically adjustable.

Title: Means for bending the rolls of rolling machines
Inventor: SHAPIRO URIEL GEORGE
IPC: B29B7/68
Filed: 1956-11-15
Abstract: 820,225. Roller sheeting-machines. COMMERCIAL PLASTICS Ltd. Oct. 22, 1957 [Nov. 15, 1956], No. 34920/56. Class 87(2). [Also in Groups VIII, XXII and XXXIV] A turning couple is applied to each end of one of the rollers of a rolling machine acting in a plane containing the axis of the roller and the axis of a co-operating adjacent roller so as to tend to bend the first roller about its middle and thereby to compensate for or correct for de- '  flection caused during the rolling operation, the turning means being independent of the main bearings of the roller. The shaft of the roller 4, carried in bearings 7, is extended at 5, 6 and the extensions are enclosed by bearings 13 in housings 14 from each of which depends a lever arm 15. A turning couple, acting in the plane of the roller 4 and the adjacent roller 3, is applied to the shaft end by moving the end of the lever arm 15 under hydraulic pressure. Clamped by a semicircular plate 37 on the end of each lever arm is a hydraulic cylinder 16 in which is a double-acting piston 17 from which extend, in both directions, stems 18, 19 the rounded ends 41, 42 of which are in contact with facing plates 43, 44 on walls 45, 46 of a fixed bracket 47. The lever arm 15 is restrained from sideways movement by the engagement of projections 49 therefrom with slots formed in plates 51 fixed to the walls 45, 46. The lever arm 15 is free to float up and down between the walls 45, 46 to allow adjustment of the positions of the rollers by means of screws 10. Hydraulic fluid forced into the cylinder on one side of the piston or the other thus results in the application of force in either direction, as determined by a change over valve in the fluid pressure system. Each bearing 13 comprises two races of tapered rollers and a couple is applied by the top rollers of one race pressing downwards, and the bottom rollers of the other race pressing upwards on the shaft extension. To permit the roller 4 to bend it passes through plain bushes in the main bearings 7 with slight clearance ; or the bearings 7 may be selfaligning. By applying the same hydraulic pressure to both the cylinders 16 unbalanced axial forces on the bearings 7 are avoided. In a modification, instead of each lever arm 15 carrying a hydraulic cylinder fitted with a stationary piston, a single stationary cylinder may be provided midway between the two lever arms 15 and fitted with two spaced movable pistons respectively coupled to the arms. The turning couple may be applied to any one or more of the rollers of the machine.
