Abstract: 810,962. Discharge tube relay circuits. BLEACHERS' ASSOCIATION Ltd., and POTTER, H. May 21, 1957 [May 22, 1956], No. 15719/56. Addition to 749,325. Class 40 (6). [Also in Group XIX] A device for detecting irregularities on the surface of a roller (see Group XIX) produces an electrical output from a microphone M when an irregularity is encountered. This output. is amplified by a system employing resistancecapacity coupling between pentode valves P1, P2, and is applied. to a thyratron T. On becoming conductive the thyratron T energizes a relay having two normally open pairs of contacts K1, K2, and one normally closed pair of contacts K3. On energization K1, K2 close and K3 open. This action connects. the thyratron anode and one terminal of the relay to the thyratron cathode, which is disconnected from the negative supply by the opening of contacts K3. The relay is then maintained energized by current drawn from one or the other of two condensers C1, C2 which are of different capacity. The condenser having been charged prior to firing of the thyratron, the capacity will determine the length of tune the relay is energized. The contacts K2 on closing, energize warning indicating or control means (not shown).

Title: Improvements in or relating to liquid blast electric circuit breakers
IPC: H01H33/84
Filed: 1954-05-31
Abstract: 776,668. Liquid-blast switches. GENERAL ELECTRIC CO., Ltd., and TAYLOR, S. Aug. 31, 1955 [May 31, 1954], No. 16088/54. Class 38(5)  In an impulse type liquid-blast switch, liquid, e.g. oil, under relatively high pressure is applied above a piston 20 to open the contacts 15, 19 and to cause a flow of oil through the arc space. As the moving contact rod is moved down by the piston, an aperture 28 in the rod 19 is first moved below the top of the cylinder 12 so that oil can flow into and through the hollow contact 19 to the arcing space. When the contacts have. separated by a further amount, one or more larger apertures 28 move below the top of the cylinder so that a more powerful flow of oil is obtained. When the contacts are fully open, the end of a guide rod 21 plugs a hole 29 in the hollow contact rod 19 and stops the flow of oil. A spring 24 closes the contacts when the oil pressure is cut off. A number of the units shown may each be supported on pillar insulation 3 and be grouped around a central hollow insulator 2 through which pressure oil may be supplied to a chamber 32 from which oil pipes radiate to the respective switch units. A piston 8 biased by a spring 31 in the chamber permits the impulse to be imparted to arccontaminated oil 7 without fouling clean oil 6 from the pressure source which may be of the pneumatic-hydraulic type. According to the Provisional Specification a rubber bag may be used in place of the piston 8.

An incubator, adapted to be constructed as a separate unit or as one of a series is formed with an incubating section consisting of one or more lower chambers each designed to receive a number of egg trays 25, access to the pair of chambers shown being obtained through doors 23, 24. These doors are double-walled, vertical passages extending between the walls, and are hinged together to the partition between the chambers, their free ends being latched by catches 36 to the side walls. The rear of the incubator is also double-walled with air passages extending between the walls. Heating pipes 47, 48, extend in pairs close to the front and the rear walls between the top egg tray and the top wall of the incubating section. A vertical shaft 50, preferably driven by an electric motor, carries an air fan composed of an horizontal rib 53 and vertical arcuate wing 54, which is situated approximately midway between the pairs of heating pipes in a chamber having a thin metal strip top 57 and a bottom 59. Both top and bottom are provided with central inlet openings for air which reaches the upper opening through a passage 65 formed in the top walls 56, 58 of the incubator section and which reaches the lower opening after passing over the egg trays. The air is forced outwards by the fan and passes over moisture fans 103 to the air passages at the front and rear of the incubator into the lower part of the incubator. Horizontal pulleys provided with mixing arms 71 are arranged in the space below the egg trays and are driven by a belt from the shaft 50 to mix all the air passing from the front and rear air passages. An opening 76, which may be left constantly open, admits fresh air to the fan-chamber and the admission of more air through another opening 77 is controlled by a thermostat, of which the lever is fitted with contacts to cause electric actuation of an audible signal if the temperature in the incubator should rise or fall beyond set limits. Another opening 78 acts as a vent to withdraw air and two other doors 79 may be opened to permit the insertion of a rod to adjust the position of covers upon the moisture trays. Electric heaters 110 are fitted in the fan-chamber and are controlled by a thermostat, a hand switch also being provided. A lamp 114 is included in the heating circuit to indicate if the heaters 110 are in use. Hatching chambers are arranged above the incubating chambers, each hatching chamber being provided with a door 115 large enough for the insertion of one egg tray- Air is admitted through a slot 117 and passes across a humidifying fan 118 under a baffle 119; it escapes finally through a thermostatically controlled damper 116.

Title: Improvements in sheet feeding mechanism
IPC: B65H3/08
Filed: 1936-06-09
Abstract: 476,503. Feeding sheets. CROWN CORK & SEAL CO., Inc. June 9, 1936, No. 16143. Convention date, May 8. [Class 100 (i)] In a sheet-feeding mechanism, the sheets are fed from a stack 51 by means of sheetengaging devices 172 operated from a reciprocating carriage 157 sliding on a trackway 152, the operating means for the carriage comprising an adjustable link 158 attached to a lever 652 operable by a cam 601 arranged between the lever 652 and a second lever 656 which can operate the lever 652 through a flexible connection. The invention is described in connection with a machine in which the rear edges of the sheets are separated from the stack 51 by means of mechanism as set forth in Specification 476,502, and a sheet stripper 62 prevents double feed as described in Specification 476,522. The sheet-engaging device 172 are in the form of suction nozzles, one carried by a rod 173 at each side of the pile. Each nozzle 172 is carried by a pair of parallel links 175, and the height of the nozzle is controlled by means of a roller 177 on one of the links which moves over a fixed cam 154 as the carriage 157 reciprocates. When the roller 177 rests on the low part of the cam 154, the nozzle 172 occupies the position shown in dotted lines. It is moved to the full line position in Fig. 1 by the action of the high part 601a of the cam 601 on a roller 653 carried by the lever 652, and the sheet is thus carried into contact with forwarding rollers 64, 66 which advance the sheet over a feed table 65. The nozzle 172 is returned to its dotted line position by the action of the high part 601a of the cam on the lever 656 which transmits its motion to the lever 652 by means of a yoke 659 fitted with a spring 665 serving to press the lever 652 backwards until the nozzle engages the pile. When this happens, owing to the resilient operation of the lever no breakage is likely to occur. A pin-and-slot connection between the lever 654 and the yoke 659 allows relative movement between these parts.

Title: Improved printing process
IPC: B41M1/26
Filed: 1928-06-05
Abstract: 318,567. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 5, 1928. Printing processes.-Non-resilient bases, such as metal, wood, artificial resins, vulcanized fibre, or stone, are printed with coloured or colourless coatings or designs in practically anhydrous lacquers containing cellulose esters or ethers by means of intaglio, offset, lithographic or other printing-machines. The products obtained are strongly resistant against mechanical or chemical action, and successive printings, for example, in different colours, can be applied to each other without intermediate drying. In the case of wood, stone, or artificial compositions, the surface is first rendered smooth and even by priming with lacquer, oil paint, filling-compositions, &c., which also serves to prevent the printed lacquer from being pulled off by the printing-surface. In order to avoid difficulties due to the rapid drying of the printing-lacquer, printing plates or rollers, which are etched or engraved very deeply, are employed. A protecting layer of transparent lacquer or varnish may be applied to the prints. A lacquer for printing on tin plate is obtained by stirring aluminium-bronze colour into a lacquer consisting of dry nitrocellulose, alcohol, phthalic dibutyl ester, and ethylene glycol monoethyl ether. The aluminium-bronze may be replaced by Prussian blue, or other inorganic or organic pigments on dyestuffs. A mixture of the dyestuff known as " Hansa yellow GT paste " and ethylene glycol monomethyl ether acetate may be stirred into a lacquer consisting of acetyl cellulose, phthalic dimethyl ester, and the glycol ester. Solutions of the coloured masses described in Specification 247,288, [Class 95, Paints &c.], may be employed, and gums resins, oils, varnishes, &c., may be incorporated in the lacquers. Iron plate may be coated with a spraying-lacquer consisting of dry nitrocellulose, mastic resin, zinc white, phthalic dibutyl ester, alcohol, toluene, butyl acetate, and butanol, after which the surface is printed with a lacquer consisting of dry nitrocellulose, phthalic dibutyl ester, phthalic diethyl ester, lampblack, and the ethyl ester of glycollic acid. The printed impression may be sprayed with a lacquer consisting of dry nitrocellulose, dibutyl phthalate, butyl acetate, butanol, alcohol, and toluene. A lacquer for printing on tinfoil by means of an intaglio printing-machine is prepared by stirring gold-bronze into a lacquer composed of ethyl cellulose, dibutyl phthalate, esterified colophony, xylene, butanol, and ethylene glycol monoethyl ether.
