Abstract: 1301281 Finishing edges of and seaming non-metallic sheet material SHOE & ALLIED TRADES RESEARCH ASSOCIATION 24 Feb 1970 [25 Feb 1969 2 Aug 1969] 38820/69 and 10080/69 Heading B5K An edge of heat-deformable synthetic leather sheet material is treated by bringing the edge into contact with a heated forming member 3 having a surface 4 corresponding in profile to that required of the edge and effecting relative movement between the sheet material and the member 3 to deform successive parts of the edge to the required profile. Preferably, the sheet material comprises a poromeric material having an inner coriacious zone and an outer grain or finish zone and is cut to form a component of a shoe upper. In one embodiment, Fig. 2, the member 3 is made of iron and has integral prongs 5 clamped in a holder 6 and connected to an A.O. source 7 and a regulating rheostat 8. The current passes through the member 3 to heat the surface 4 to a temperature of 250-600‹ C., preferably 300‹ C. The holder 6 is adjustable in position both horizontally and vertically relative to a work surface on which the sheet material is positioned. Relative movement between the material and the member 3 is effected by continuous movement of the material by a feeding mechanism. In another embodiment, Fig. 3, the holder 6<SP>1</SP> has slots in which the prongs 5<SP>1</SP> are vertically adjustable, an aperture 21 in the work surface 2 permitting this adjustment. Horizontal adjustment of the holder 6<SP>1</SP> may be effected by shifting a support 20 therefor which is slidably mounted on a main support 15. Feeding of the material is effected by the engagement of a freely rotatable milled wheel 12 with a driven milled wheel 11 protruding slightly through an aperture 10. The wheel 12 is journalled on a curved lever 19 fixed to a shaft 16 slidable in a tube 13. A spring 18 urges the lever 19 to bring the wheel 12 down against the wheel 11 at a point slightly forward of the top dead centre position of the wheel 11. The invention is applicable to the finishing of a closed seam at the heel of a shoe upper. Two superposed sheets (30), (31), Fig. 4 (not shown), are welded and trimmed by an electrode (32) or stitched and then passed through the machine of Fig. 3 to round-off the edge. Subsequently, the sheets are opened out. If the material only has a thin coloured topcoat and an uncoloured or lightly coloured substrate, the edge may be treated, prior to heating, with a dye or pigment, from an ink-fed roller, so as to colour the edge so that, after heating, it resembles the appearance of the free topcoat surface.

Abstract: 1304833 Radar HUGHES AIRCRAFT CO 11 Sept 1968 43294/68 Heading H4D In a track-while-scan radar system, pulse radar surveillance is effected in both elevation and azimuth. The target signals are stored and "updated" on the assumption that a meaning- ful target would move out of a scanned volume in a given time. False target reports are reduced by the automatic control of the detection sensitivity. The surveyed space is divided into incremental volumes each containing 64 range bins and the updating occurs during three successive revolutions of antenna 16. The video return signals are digitized at the quantizer 24 into 3-bit codes, the numerical value of which represents the excess of the amplitude from each range bin over a threshold value. The correlator 26 produces target reports from an acceptable hit pattern. The memory, 40, stores a multibit code, e.g. 5 bits, for each incremental volume of the radar surveillance volume. The code represents the prior history of detected targets or target reports from each of the range bins in the particular incremental volume and is used to control the detection sensitivity of targets from each of the range bins in the incremental volume. The incremental volume cell generator 44, which receives range, azimuth, and elevation signals provides instructions to the memory 40. The output from 40 causes the logic stage 42 to control the subtractor 28 which modifies the coded signals from 24, i.e. all coded video signals from the incremental volume are reduced by 1, providing stricter detection criteria. All target reports are blanked from an incremental volume if, despite a predetermined reduction of sensitivity, target reports are still received from any of the range bins. In a second embodiment (Fig. 14) the control is effected in addition as a function of the rate at which target reports are provided by correlator 26 and as a function of the rate at which coded video returns above a certain level are provided by quantizer 24.
