Abstract: 1,093,474. Cathode-ray tubes. I. K. GIRSHOVICHUS, and S. K. GIRSHOVICHUS. Feb. 4, 1965, No. 4838/65. Heading HID. [Also in Division G5] Information is recorded on a magnetic carrier 15 disposed adjacent the end wall of a cathode-ray tube by means of an electron beam impinging on a conductive layer 10 on the inner wall of the tube. It is stated that the beam builds up a momentary charge on the layer 10, and changes in the charge produce a magnetic field which influences the record 15. Deflection of the beam is such that it does not move appreciably across the target for the duration of a pulse being recorded. A high density of recording may be achieved, and signals of complex waveform may be recorded.

Abstract: 564,753. Photo-mechanical printing- surfaces. AHLEN & AKERLUNDS FORLAG, PETREN, T., and STERNBERG, E. K. W. April 2, 1943, No. 5340. [Class 98 (ii)] In the production of a planographic printing- surface on a metal plate having the property of repelling greasy ink by applying a photographic sensitive layer to the plate, forming a latent image therein, developing the image so as to lay bare portions of the plate, applying to such portions a solution containing a compound of a metal which has a lower electrolytic solution pressure and also a greater receptivity for greasy printing ink than the metal of the plate so as to deposit a thin layer of the firstmentioned metal on the areas laid bare, and thereafter removing the remainder of the' photographic layer, the plate consists of or is coated with a non-oxidisable metal or metal alloy such as rust-resisting steel or steel alloy, or chromium or an alloy thereof. The solution applied to the plate after development may contain a compound of a metal which will form an alloy with the base metal; the compound may be cuprous chloride when the base metal is steel. The base-plate is first mechanically roughened or grained in known manner, and cleaned as with a solution containing formic acid, alum and nitric acid. It is coated with a light-sensitive layer which may be compounded of ammonium bichromate, manganese sulphate, albumin, gum arabic, ammonia and water, exposed, developed as with a solution containing calcium chloride, lactic acid, and alcohol, which removes the unexposed parts of the sensitive layer, laying bare areas of the base metal which are then rendered ink-receptive as by treatment with a solution containing calcium chloride, ferric chloride, nitric acid, hydrochloric acid and cuprous chloride, which deposits a very thin layer of copper on the bared areas of the base metal. After making any desired corrections, the plate is made ready for printing in the usual way by greasing the surface and washing away the remaining hardened parts of the photographic layer covering the areas of the base which are to be waterreceptive and ink-repellant in the printing operation.

Filed: 1929-02-19
Abstract: 306,901. Michelin et Cie. Feb. 27, 1928, [Convention date]. Deflation, indicating. - An automatic device for indicating deflation of pneumatic tyres by the completion of an electric circuit of a lamp on the dashboard of the vehicle comprises a contact member on the wheel adapted, on a fall in pressure in the tyre, to make contact with a ring on the axle. The contact member consists of a spring pressed plunger 1, which is mounted in a cylinder 2 on the hub 11 and is normally retained in the out of contact position by a catch 13 engaging the groove 12. The catch is adjustably carried in a plunger member 14 slidably mounted in a chamber 15 which communicates by a pipe 17 with the air chamber of the tyre. The plunger member 14 bears on a spring 20 which is adjusted by means of the threaded plate 21 to balance the minimum airpressure required in the tyre which is exerted on the flexible membrane 18. When the airpressure falls below the minimum, the spring 20 moves the plunger 14 carrying the detent 13 out of the groove 12 and thus releases the plunger 1 which makes contact with the disc 5 through the ball-contact 26. Another form of the inven. tion is shown in Fig. 3 in which the release mechanism for the contact plunger is mounted in the wheel rim. The bead 27 of the catch 13 is in direct contact with the inner tube of the tyre. The nose of the catch 13 normally engages a groove 31 formed in the periphery of the drum 32 on which is wound one end of a Bowden wire 33 whose other end is connected to the contactplunger 1. To set the apparatus, the drum 32 is turned by means of the squared head 34 until the end of the groove 31 engages with the nose of the catch 13.
