Title: Switch chamber for high tension pressure gas switches and process for its production
Inventor: MAKELBURG HEINZ
IPC: H01H33/70
Filed: 1966-10-07
Abstract: 1,119,473. Insulators. TRANSFORMATORENWERK KARL LIEBKNECHT VEB. 7 Oct., 1966, No. 44931/66. Heading H2C. [Also in Division H1] A switch chamber of a high tension pressure gas switch of the kind comprising a ceramic insulator 1 with a strengthening insulating cylinder 2 therein has the annular gap therebetween almost completely filled with an insulating compound 4 leaving a very small residual volume 3 to which the pressure gas has access via a small passage and circumferential groove 7 in the cylinder 2, thus preventing dielectric breakdown due to voids between the compound 4 and insulator 1 yet restricting the volume of gas available to accelerate fragments of the insulator 1 should it become fractured. The compound 4 is a thermo-setting synthetic resin which sets at a temperature not greater than the maximum switch-operating temperature, and a parting agent, such as silicone grease, is coated on the inside wall of the insulator 1 to prevent adhesion thereto and possible flaking thereof. A longitudinal slit 5 in the compound 4 prevents extra strain on the insulator 1 due to thermal expansion of the compound.

Abstract: 1,023,271. Transistor limiting circuits for radio receivers. COMMUNICATIONS PATENTS. Ltd. Nov. 18, 1963, No. 45364/63. Heading H3T. In a circuit for protecting the input stage of a transistor radio receiver from received largeamplitude signals, a transistor 18 supplies constant current to a diode 13 in the input signal path, whereby for normal-amplitude received signals applied from aerial-input terminal 15 via capacitor 14 the diode is forwardly biased at all times, so that the received signal passes substantially unattenuated to a transformer 10 coupling the signal to the input transistor, but for large-amplitude signals the diode limits over a portion of each alternating-current cycle so reducing the signal amplitude applied to the transformer 10. When the input-signal amplitude becomes so large that during the negative-going half-cycle more current seeks to flow into capacitor 14 than can be supplied by transistor 18, diode 13 is cut off for a portion of each cycle and owing to the rectifying action the junction of diode 13 and capacitor 14 becomes negatively biased, so that the mean current flowing through the diode stabilizes itself at the value of constant current supplied by diode 18. Diodes 25, 26 also limit the signal applied to transformer 10, especially during a rapid change before capacitors 14 and 23 have had time to become charged.

Title: Xerographic charge transfer process
Inventor: WEIGL JOHN WOLFGANG
IPC: G03G15/18
Filed: 1963-11-19
Abstract: 1,066,249. Transferring electrostatic images. GENERAL ANILINE & FILM CORPORATION. Nov. 19, 1963 [Dec. 28, 1962], No.45627/63. Heading G2H. In order to provide a temporarily conducting interlayer in a charge receiving sheet for use in effecting a latent electrostatic image transfer, under conditions of very low relative humidity, a photo-conductive insulating layer or laminar zone underlies the charge receiving surface and is uniformly exposed to actinic radiation immediately prior to transfer. As shown in Fig. 1, a photo-conductive insulating layer 32 contains zinc oxide produced by the French process and underlies an insulating resin layer 33 which may contain a pigment such as mica, silican or titania. Both layers are supported on a paper or plastic film base 31. The layer 32 is made conductive by passing the strip beneath a fluorescent lamp 25. The conductivity is retained while the layer is earthed at 69 and an electrostatic latent image is transferred from photo-conducting insulating layer 37, under the influence of an electric field from high voltage generator 39a.. The charge image 42 on layer 33 is subsequently developed and fixed. In Fig. 4 (not shown) the insulating resin layer is omitted and the photo-conductive insulating zinc oxide layer 32" is so absorptive at the wavelengths used for exposure, that only the part of the layer nearer the lamp 25b is made conductive. The transfer of charge is effected by bringing the photo-conductive layers 37' and 32" into contact. In another form, Fig. 7 (not shown) the receiving strip is charged prior to transfer and the transferred image is developed with a liquid toner and fixed by drying with a current of warm air. In a further form Fig. 6 (not shown), in which the primary image is formed electrically on a rotary cylindrical surface, the residual charge is removed from this surface by wiping it with a sponge roller dipping into a container of earthed conductive liquid. A method of exposing the strip prior to image transfer, to a dot pattern on a transparent cylinder is described. The resultant image is stated to be of use in the preparation of half-tone plates. Several constructions of sheet material are described and in one of these the base layer 36 is used as the image receiving layer. In another construction the photo-conductive zone is formed in a paper base layer by impregnating one face of the paper with photo-conductive material. This face is then coated with a charge receiving insulating layer.

Abstract: 1,274,252. Electron microscopes. SIEMENS A.G. 22 Sept., 1969 [23 Sept., 1968], No. 46673/69. Heading H1D. In an electron beam microscope, especially of the scanning type, wherein a beam along the Z axis (Fig. 1) bombards a sample at P, the sample preferably being a crystalline object having a surface the normal to which intersects the sphere O at C, stereoscopic images are produced by first rotating the object about the Z axis until the point C moves to C<SP>11</SP> where the perpendicular to the Y axis makes an angle ##/2 with the YZ plane, and subsequently rotating the object about the Y axis through the stereoscopic angle ## so that C<SP>11</SP> moves to Cl; since the electron beam is equally inclined to the surface at C<SP>11</SP> and Cl respectively when producing each image, the image intensity remains unchanged. In an alternative procedure the object is rotated through the sterepscopic angle about an axis parallel to the normal to the surface being observed. Fig. 2 shows a suitable support for the object P which is mounted on a U-shaped holder H2 which is rotatable about the X axis in a frame R which is rotatable about the Y axis in a U-shaped holder H1; this is mounted on a shaft A rotatable about the Z axis and translatable along three axes by slides S1-S3.
