Title: Making cellular polymeric articles having surface relief  patterns
IPC: B44C1/20
Filed: 1974-10-23
Abstract: 1472078 Relief patterned cellular articles EIWA CHEMICAL INDUSTRIAL CO Ltd 23 Oct 1974 45920/74 Heading C3C [Also in Division G2] Relief patterns on cellular polymeric articles are produced by exposing a thermoplastic polymer containing azodicarbonamide to the pattern using light of wavelengths of 100 to 500 n.m. to inactivate the azodicarbonamide and then heating the article to above the decomposition temperature of the azodicarbonamide to release gases therefrom and produce the relief pattern. Heating is preferably between 180‹ and 220‹ C. In the examples polyethylene, polyvinyl chloride, acrylonitrile-butadiene-styrene resin or ethylene/vinyl acetate copolymer with optionally plasticizers, e.g. dioctyl phthalate, stabilizers, e.g. Cd-Ba complex salts or dicumyl peroxide were mixed with azodicarbonamide, formed into sheets which were printed or covered with a pattern, irradiated with ultra-violet light and then heated in ovens or a salt bath to form embossed expanded sheets.

Stacked articles 1 (Fig. 3) are drawn from a conveyer or conveyers 2, 2a by a reciprocating stripper device 4 on to a stacker 6 (Fig. 2) which raises them to a collection chamber 10 from which they are inserted into boxes. In the form shown, a box 17 (Fig. 1) is pulled by a suction head from a box magazine 18 and opened over the collection chamber 10. As one stack of articles 1 is stripped from a conveyer, the articles are retained on the other conveyer by the flange of the stripper device (see Fig. 3). After the stacker has stacked four lots of articles into the collection chamber 10, it then carries out its full stroke controlled by a counter 26 to move the stack 19 (Fig. 2) into the box 17. The height of the stacks of articles fed to the stacker 6 is controlled by feelers 21b, 25b (Fig. 3). The movements of the stripping device 4, the stacker 6 and the boxes 17 are controlled by switches.

Abstract: 1285176 Photo-electric position finding BRITISH AIRCRAFT CORP Ltd 9 Oct 1969 [10 Oct 1968] 48085/68 Heading H4D Apparatus for measuring the movement of a vehicle over the ground comprises a reference photo-cell receiving light directly from a light source a second photo-cell receiving light from said source after reflection from the ground, means for modulating the light reaching the photo-cells by a continuously moving pattern, whereby ratio of the frequency of the fluctuations in the signal from the second photo-cell with respect to that of the first is constant if the vehicle is stationary and is different if the vehicle has a component of movement in the direction of the moving pattern. The moving pattern is produced by a rotating "cage" 14 around the source 10. Due to variations in the reflectivity of the ground the frequency of the light intensity variations received by photo-cell B increases if the vehicle moves in a direction opposite to the direction of the moving pattern and vice versa. The change in frequency is detected and used to calculate the distance moved . Two orthogonal systems may be mounted on a stabilized platform to provide an absolute measurement of the vehicle position relative to a known starting point. The positions of the source and photocells may be reversed (Fig. 3, not shown) and the light fed to the photo-cells via optical fibres instead of the lens systems shown.
