Title: Electric overload tripping relay
IPC: H01H71/20
Filed: 1961-08-30
Abstract: 998,276. Electrically - tripped switches. SQUARE D CO. Aug. 30, 1961 [Dec. 22, 1960], No. 31177/61. Heading H2B. A circuit-breaker has a tripping mechanism, including two levers pivoted on a common movable member and biased so that when one of the levers is released by the overload responsive assembly the common member is moved by the biasing means to allow the circuitbreaker contacts to open. As shown, the common member is a pin 65 movable in slots in casing parts and carrying a lever 61 having a boss 61a on which the lever 60 is mounted. A leaf spring 67 engages a limb 62 of the lever 61 so that a projection 64 on the other limb 63 of the lever 61 is urged against and retained by a toothed wheel 25 of a " solder pot " overload assembly (not shown). A spring 68 urges lever 60 clockwise (Fig. 3) about the pin 65 so that its leg 58 engages a contact spring 45 to urge it into engagement with a fixed contact 51. When the solder melts to allow rotation of the wheel 25 and upward movement of the lever 61 the movement of the pin 65 causes the lever 60 to rotate about a casing projection 76 to allow the moving contact spring to disengage contact 51 and engage a contact 50. After such tripping action (Fig. 6, not shown), the circuitbreaker can be reclosed by depression and release of an actuator 33 which when moved downwards engages the end 74 of the line 59 of the lever 60 to move the levers 60, 61 downward. When the actuator 33 is released for return movement due to its biasing spring 71 the projection 64 engages the wheel 25 to stop the upward movement of the levers 60, 61 and the spring 68 turns the lever 60 to the position shown to close contacts 45, 51.

Title: Improvements relating to electric wave attenuators
IPC: H03H7/01
Filed: 1947-11-27
Abstract: 645,886. Electric attenuators. POLYTECHNIC INSTITUTE OF BROOKLYN. Nov. 27, 1947, No. 31472. Convention date, Dec. 4, 1946. [Class 40 (viii)] In an attenuator comprising a loss-producing plate arranged for insertion through a longitudinal slot in one side of a wave-guide by means of an adjusting member, the mechanical link between the adjusting member and the plate is designed to produce a linear relationship between the movement of the adjusting member and the attenuation produced by the plate. The plate 9 is made of thin metal-coated glass carried by a block 8 which is constrained to move parallel to wave-guide 1 by links 10a, 10b, and is biassed by a spring 11 against an adjusting screw 12. The lower part of plate 9 enters a slot 17 in the upper side of wave-guide 1, the lower edge of the plate being curved at 9a to effect matching. A magnetic choke, comprising bars 16 of dust iron placed on each side of slot 17, prevents loss of energy through the slot. The longitudinal movement of plate 9 under the action of screw 12 is measured by a micrometer 14, having an operating plunger 14b engaging one end of block 8. This movement is, due to the action of links 10a, 10b, proportional to the attenuation in decibels produced by the plate 9. Specification 643,494, [Group XI], is referred to. Reference has been directed by the Comptroller to Specification 617,919.

Title: Manufacture of n:n-dialkyl-dipyrazolanthronyls
IPC: C09B5/08
Filed: 1937-07-30
Abstract: N : N1-dialkyl-2 : 21-dipyrazolanthronyls are manufactured by treating a 2 : 21-dipyrazolanthronyl simultaneously or successively with two alkylating agents, one providing an alkyl residue containing an alkoxy group and the other a branched alkyl residue containing no alkoxy group, or by treating an N-monoisoalkyl-2 : 21-dipyrazolanthronyl, containing no alkoxy group in the isoalkyl residue, with an alkoxyalkylating agent, or by treating an N-monoalkoxyalkyl-2 : 21-dipyrazolanthronyl, e.g. N-mono-methoxymethyl-, methoxyethyl-, ethoxyethyl- or butoxyethyl-2 : 21-dipyrazolanthronyl, with an alkylating agent providing a branched alkyl residue containing no alkoxy group.  The products may be treated with a halogenating agent.  Suitable isoalkylating agents are isoalcohols, e.g. isopropyl, isobutyl or isoamyl alcohol, esters thereof, e.g. the hydrogen halide esters, such as isopropyl chloride or the isobutyl or isoamyl halides, the sulphuric esters and especially the arylsulphonic acid esters, also esters of polyhydric isoalcohols containing halogen, e.g. the p-toluenesulphonic acid ester of a  : a 1-dichlorhydrin. The reaction may be effected at high temperature, e.g. 120-200 DEG  C., in an open vessel or under pressure, if desired in the presence of a solvent or diluent, e.g. nitrobenzene, chlorobenzene, 1 : 2 : 4-trichlorobenzene, amyl alcohol, naphthalene or anisole.  When using an isoalcohol still containing a free hydroxyl group it is preferable to alkylate in the presence of an acid, e.g. sulphuric acid, whilst with an ester it is preferable to use an alkali salt of the 2 : 21-dipyrazolanthronyl. The products may be purified by crystallization, by conversion into their salts with strong acids or by treatment with oxidizing agents, e.g. alkali hypochlorite solution, and may be converted into their leuco-derivatives, e.g. leuco-sulphuric acid esters.  They are dye stuffs or intermediates therefor, and may be used, if desired in admixture with N : N1-dimethyl-, diethyl-, dimethoxyethyl or diethoxyethyl-2 : 21-dipyrazolanthronyls, for dyeing or printing vegetable fibres, e.g. cotton, for dyeing artificial silk, e.g. acetate artificial silk, or for colouring lacquers and plastic masses.  In an example, the dipotassium salt of 2 : 21-dipyrazolanthronyl is heated in chlorobenzene in the presence of potassium carbonate with p-toluenesulphonic acid methoxyethyl and isopropyl esters, in either order or simultaneously.  The methoxyethyl ester may be replaced by b -bromethyl methyl ether.  The product dyes cotton red shades. Similar dyestuffs are obtained if the methoxyethyl ester is replaced by the ethoxyethyl ester and/or the isopropyl ester by the sec. butyl ester.

Abstract: 1314655 Air classifier FIVES LILLE-CAIL 6 July 1971 [7 July 1970] 31739/71 Headings B2H and B2P An air classifier for separating granular material into two fractions of different grain size comprises a vertical, cylindrical classifying chamber 12 provided with an outlet 35 at its upper portion, a rotary plate 24 for dispersing material to be classified situated in the chamber, a deflector 38 in the form of a cap-shaped member arranged coaxially in the chamber below the dispersion plate 24 so as to intercept a falling stream 52 of mainly large particles of the material, the peripheral surface of the deflector 38 flaring downwardly to a lower edge of a diameter smaller than that of the chamber 12 and situated above a wall element, e.g. the conical bottom 16 of the chamber, which narrows downwardly, and an air admission conduit 36 which opens out below the deflector 38 axially of the chamber. A second deflector in the form of an inverted truncated cone 42 is fixed to the classifying chamber casing 10 and has a frusto-conical plate 44 welded to its lower edge and to the casing so that the air current issuing from under the deflector 38 passes twice through the stream 52 and entrains with it any fine particles present therein. The material to be classified is fed through a supply conduit 32, falls on to the plate 24 and is projected by centrifugal force beyond the edge of the plate where it is met by the upward air current which carries the fine particles upwards towards outlets 35. Any large particles entrained by the air is removed as the air current passes through a bladed wheel 28 fixed on the plate 24. The outlets 35 are connected to cyclones 48 which are in turn connected to a fan 50 which recirculates particle-free air to the classifying chamber 12. Cold air or hot gases may be introduced into the chamber 12 with the recycled air to cool or dry the material. The deflectors 38 and 48 may alternatively be vertically adjustable.
