Title: Process of making styrol
IPC: C07C5/54
Filed: 1930-04-01
Abstract: Ethyl benzene mixed with benzene is subjected to cracking temperatures, and styrol is separated from the mixture of styrol, benzene, and byeproducts which is produced.  One or more substances which favour the dehydrogenation either chemically, by forming stable compounds with the hydrogen which is produced, or physically by reducing the partial pressure of the ethyl benzene, may be present during the reaction.  Examples of dehydrogenating substances which act chemically are carbon disulphide, carbon tetrachloride, ethylene, and sulphur; nitrogen, ammonia, carbon dioxide, and volatile organic compounds such as ethyl alcohol or acetone act physically; while ethylene chloride, sulphur monochloride, sulphur dichloride, and sulphur dioxide act both chemically and physically.  Suitable mixtures of such substances are sulphur and ethylene chloride or sulphur and acetone.  The reaction may be carried out in an iron or chemical tube furnace, which may be heated electrically, and the temperature in the reaction zone may be in the range 600-750 DEG  C., and preferably in the range 675-720 DEG  C.  The products are purified by steam distillation, and the recovered hydrocarbon other than styrol may be returned to the reaction.  An example is given.

[Also in Division H1] A semi-conductor rectifier 16 is secured to a conductive mounting- plate 22 by bonding a cup shaped member 21 of thermally - conducting electrically insulating material such as beryllium oxide to both the rectifier and the plate. The cup is fitted over a mass 20 of metal which is secured to one of the rectifier terminals 19, and its base is secured directly to the mounting plate. In the example quoted, beryllium oxide, the cup is secured to both rectifier and plate by solder, its surface first being coated with tungsten iron or molybdenum manganese. The plate 22 is intended to be secured, e.g. by bolts 23, to a heat sink 13 which may be part of the casing of a transformer (Fig. 1, not shown) or electric machine with which the rectifier is associated. In particular the machine or transformer may be in an oil-filled casing and fins on the inside of the easing wall to which the rectifier is attached may be cooled by circulation of the oil over the fins. Fig. 1 (not shown) depicts six such rectifiers attached to the outside of such a casing wall and covered by a box-like attachment (15) which may be sealed to the casing. Such an arrangement may be employed in a so-called brushless dynamo-electric machine in which the rectifiers derive from an A.C. current in one winding a D.C. current for energizing another winding.

Title: Method and an apparatus for the information transmitting capabili ties of image forming systems
IPC: G02B27/58
Filed: 1970-03-05
Abstract: 1307894 Diffraction processes BAYER A G 5 March 1970 [8 March 1969] 10586/70 Heading G2J [Also in Divisions H3-5] In an imaging process the transmitted information is increased by transforming the spatial frequencies of the structure to be imaged into a smaller range of spatial frequencies by the diffraction of subwaves (defined), the diffraction being effected either by illuminating the object with sub-waves or by illuminating the object with homogeneous waves and thereafter diffracting the sub-waves produced at the object on an analyser grating. In one embodiment sub-waves of spatial frequency kg are produced by illuminating a grating 2 with laser light 1, the grating constant being small compared to the wavelength of the light. (Alternatively they may be formed by total reflection). The sub-waves are diffracted by an object 3, of spatial frequency k a , within their range to produce homogeneous waves of spatial frequency K b  = k a  - k s . A lens 4 produces a Fourier transform of spectrum k b  at 5, but in its image plane 6 it forms a distorted magnified image of object 3. A Fourier transform 8 of this distorted image is formed and its zero and negative order frequencies masked out. A final magnified image 14 is formed by lens 10 which is not distorted because the zero order is restored direct from laser 1. This zero order has an effective point source 13 in the same plane as transform 8. If desired the final image may be formed as a hologram 15 Fig.3 by interference between the first order from transform 8 plus displaced zero order from point 13 and a reference beam 16. Reconstruction from this hologram via a lens gives the final image 14. Using holography a plurality of images of different spatial frequency can be formed. In a further embodiment the object is illuminated by homogeneous waves, and sub-waves of spatial frequency k a  are formed by diffraction at the object. The subwaves are directed to an analyser grating of period k s  to form homogeneous waves of spatial frequency k b  = k a  - k s . In a modification of this embodiment the sub-waves generated by the object are recorded holographically, the hologram being reconstructed by sub-waves to give the homogeneous waves of spatial frequency k b . In the first embodiment the grating 2 may have either a phase or an amplitude structure. In other applications the laser is replaced by other sources fo radiation such as electrons, sonic or ultrasonic radiation or X-rays.
