Title: Process for the production of corrosion-resistant coatings
IPC: C09D5/46
Filed: 1963-08-22
Abstract: Particulate polyvinyl acetals for coating applications are prepared from aliphatic aldehydes of 6 to 8 carbon atoms. Examples are given of polyvinyl capronal and polyvinyl-[2-ethyl butyral], which may be pigmented with titanium dioxide or carbon black.  There may be up to 23% unreacted vinyl alcohol units and 5% unhydrolysed vinyl ester units.ALSO:A process for the production of a plastic coating on an article comprises heating the article, to a temperature above the softening temperature of the polyvinyl acetal but below the deterioration temperature of the article, flowing discrete solid particles of a polyvinyl acetal prepared from an aliphatic aldehyde containing 6 to 8 carbon atoms ones the surface of the heated article and then cooling the coated article.  The particles may be applied by flame-spraying or by the fluidized bed process. Iron and steel rods, plates and wire are coated in examples: the process may also be applied to articles of copper, aluminium and magnesium.  Optional additives include stabilizers, pigments and plasticizers, and other polymers e.g. polyethylene, polystyrene, polyamides, epoxy resins, vinyl or acrylic resins, cellulose derivatives, chlorinated polyethers and polyacetals such as polyformaldehyde.

Abstract: 300,614. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). Nov. 16, 1927, [Convention date]. Vacuum tubes. -The supply of current to the heater of an indirectlyheated cathode is inter. rupted by heat-responsive means when the cathode has reached a predetermined temperature, the heater being then maintained at that temperature by electron bombardment from the cathode. As shown, one end of the heating wire 5 is connected with a thermostatic strip 6 mounted in the envelope, and the other end with a contact 7 separated from the strip by insulation 8. The cathode 4 consists of a cylinder coated on the outside with electron-emitting oxide. When the device is cold a circuit is completed from a battery 10 through a resistance 11, the strip 6, heater 5 and cathode 4. When the cathode is heated sufficiently the strip breaks the circuit between the heater and the cathode, and the heater, being at a positive potential, is heated by electron bombardment from the cathode, and is thus maintained at the required temperature. The battery also supplies the anode circuit. The device may be used for producing high-frequency oscillations for the excitation of a vapour lamp. For this purpose the primary 12 of a transformer is connected between the grid 3 and anode 2 and its mid-point is connected with the cathode. The secondary 13 is connected with a winding 14 surrounding the lamp. In a modification for use as a rectifier, the grid is omitted and the heater is supplied through a transformer.

Title: An improved excess electricity consumption meter
IPC: G01R11/56
Filed: 1935-12-06
Abstract: 445,762. Supply meters. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. Dec. 6, 1935, No. 33866. Convention date, Dec. 20, 1934. [Class 37] In an excess-consumption meter in which an opposing torque is produced by a spring, a rotary releasing member which is acted upon by the spring 20 is connected through a gear wheel 15 with the meter shaft 1, the shaft of the releasing member being capable of movement about the shaft 14 of gear wheel, so that on the momentary releasing of the member, which results from the overcoming of the spring by the driving force on the meter shaft, the releasing member rolls on the gear wheel and effects an uncoupling and partial unstressing of the spring, until the member is stopped by its backward movement and the spring is again coupled to the gear wheel. In the form shown the releasing member comprises a star 24 secured to a gear wheel 23 in mesh with the wheel 15, the releasing member being carried by the arm 17 of a two-armed lever loosely mounted on the shaft 14. The inner end of the spring 20 is secured to a pin 19 on the lever, while the outer end of the spring is hooked into one of a pluralitv of slots 22 in a scale drum 12 carried by hub 9 mounted in a hole 7 in a plate 5 fixed to the frame 4 of the meter. A pin 8 screwed into the hub holds the latter in position, a spring 11 providing friction between the hub and the plate 5. One arm of the star 24 normally rests against a spring stop 26 and prevents rotation of the gear wheel 15 until the driving force on the meter shaft 1 overcomes the force of the spring 20. When this occurs, the gear wheel is set in rotation in the direction shown by the arrow 27, and the lever 17 is moved with stressing of the spring 20 until the arm of the star slips off the stop 26. The lever is then moved backwards by the spring and the gear wheel 23 rolls on the wheel 15 until the next arm of the star strikes the stop 26. The tension of the spring may be adjusted approximately by connecting it to the appropriate slot 22, in the drum 12, and a fine adjustment can then be obtained by turning the drum by means of a screwdriver engaging a slot 28 on the pin 8.
