Title: Improvements in or relating to optical prisms
IPC: G02B27/14
Filed: 1937-08-26
Abstract: 501,409. Optical systems. BAUER, K., and DAESCHNER, A. Aug. 26,1937, No. 23436. Convention date, Aug. 26, 1936. [Class 97 (i)] A prism is provided with a number of internal reflecting-surfaces arranged in one or more pairs of rows, the reflecting surfaces of one row of a pair being symmetrically arranged and oppositely inclined at 90‹ with respect to those of the other row of the same pair, and the inner edge of each reflecting surface of each pair lying in the plane normal to the plane ofsymmetry containing the outer edge of the next reflecting surface in the same row, the arrangement being such that the reflecting surfaces deflect incident rays out of their original direction into a direction parallel thereto at least once and finally back into their original direction in order to increase the length of the path of the rays in the prism. Fig. 1 shows a form in which the whole of the width of a rectangular prism 1 is taken up by two rows of reflecting surfaces 2, 3. An incident ray such as 4 is reflected by one of the surfaces 2 to the next surface in the row, then to a surface 3 which reflects it to the next surface 3 by which it is deviated into its original incident direction. The length of the ray path in the prism is thus twice the width of the prism. - Fig. 2 shows a form in which only half the width of the prism is occupied by reflecting surfaces, the length of the ray path being 1À5 times the width of the prism. In Fig. 5 the prism comprises plain portions 10, 14 and two rows of reflectors 11, 13 separated by another plain portion 12. The prism may have additional reflecting surfaces to deviate the rays before or after they traverse the rows of reflectors ; in Fig. 8 the prism has a totally reflecting surface 15 at 45‹ to the incident rays so that the rays leave the prism at right-angles to their incident direction. The prism may be made by providing a number of plane-parallel plates 20 . . 23, Fig. 11, with reflecting surfaces 25, 26, 27 and cementing them together to form a block 37, Fig. 12. Sections 33, 34, 35, Fig. 12, are cut from the block with their faces at 45‹ to the reflecting surfaces and by placing two such sections together as shown in Fig. 13 and uniting them, a prism as in Fig. 1 is obtained. A prism according to the invention may be used as part of a beam-splitting system for producing a number of colour records in colour photography, in order to equalize the paths of the several beams. Fig. 17 shows a system for dividing an incident beam into three parts. The incident rays are received by a prism f having two internal partly-reflecting surfaces 42, 43 at rightangles to each other. The rays reflected by these surfaces enter prisms a, b respectively, having internal reflecting-surfaces 40, 41 which direct the rays through plain prisms c, d. The rays traversing the prism f pass through a prism e provided with rows 44, 45 of reflecting surfaces, Fig. 18, which increase the length of the path of these rays to equality with those reflected by the surfaces 42, 43.

Title: Improvements in grinding or like operations on thermoplastic materials consisting ofor containing cellulose derivatives
IPC: B02C19/00
Filed: 1931-08-21
Abstract: <PICT:0388384/IV/1> A moulding-powder containing cellulose acetate or other organic derivative of cellulose is obtained in finely divided form by grinding the material while passing a stream of cool air or other gas through the mill in order to cool the material.  Examples of the other organic derivatives of cellulose are cellulose formate, cellulose propionate, cellulose butyrate, ethyl cellulose, methyl cellulose and benzyl cellulose.  These derivatives are preferably mixed with plasticizers, such as camphor, dimethyl phthalate, diethyl phthalate, triphenyl phosphate, para ethyl toluene sulphonamide, dibutyl tartrate, triacetin, monomethyl xylene sulphonamide, &c. Cellulose acetate, a plasticizer and a volatile solvent are kneaded and rolled in heated malaxating rolls until gelatinization is completed and most of the volatile solvent evaporated from the sheet or slab.  As shown, the sheets or slabs of cellulose acetate are crushed before grinding into chips and fed to a hopper 17 from which it is discharged by a screw 18 into a duct 19 and is carried into the mill 1 by the air drawn in through the pipe 20 by the suction fan 16. The mill is provided with water jackets 4, 8 and the material ground by the pivoted hammers 25 is discharged through a grating or sieve 11 into a bag 13 housed in a chamber 14 evacuated by the pump 16.  The interior angles of the mill are curved to facilitate the cleaning of the mill.  The Specification as open to inspection under Sect. 91 refers also to the use in the process of cellulose nitrate.  This subject-matter does not appear in the Specification as accepted.

The plate B<1>, Fig. 3, may form one element of the thermocouple, the other element being a copper plate 7. Alternatively, the thermocouple may be formed entirely of the metals of the safe. Small changes of temperature may be compensated for by providing a second thermopile in differential relation to the first one.

[Also in Groups V and XX] A roller for embossing thermoplastic material such as polyvinyl chloride sheet material is prepared by photographing a surface, such as natural leather, having a pattern or grain, preparing a plurality of positive prints of the surface and arranging them as a mosaic on a backing member, retouching the joints between the prints to make them substantially indiscernible so that the mosaic simulates the appearance of a typical integral area of the original surface, photographing the mosaic to produce a negative having one dimension equal to the circumference of a roller, applying the negative to the roller and etching the roller from the negative. A piece of light-coloured leather is rubbed with a little black ink and photographed using photographic material having a high resolving power. A plurality of positive prints are made from the negative on an enlarged scale and pressed together on a backing to form a'rectangular mosaic, the joins between adjacent prints being concealed by retouching, giving continuity to the mosaic. A longitudinal cut is made along any arbitrary line and the two original edges are joined and the join retouched. The upper and lower edges now accurately match in pattern detail. The mosaic is photographed and a negative produced, and' an etched roller produced therefrom. Colouring matter may be applied from the raised portions of the roller during embossing.
