Title: Improvements in clutch mechanism
IPC: F16D11/06
Filed: 1945-12-21
Abstract: 615,637. Positive clutches. FITZPATRICK, H. J. (Clearing Machine Corporation). Dec. 21, 1945, No. 34666. [Class 80 (ii)] A positive clutch for a press has concentric driving 31, 27 and driven 21, 23 members locked for combined rotation by two locking members 42, one, 43, actuated by the other 49, which is itself actuated by a spring-loaded member 56 which may be catched 67 into an inoperative position, and automatic means 71, 65 for rendering the catch 67 inactive so that the spring-loaded member 56 may function normally. Depression of a pedal (not shown) moves a bell-crank lever 70 to move the catch 67 transversely to move the spring-loaded member 56 out of the path of the lever 49, which is loaded by a spring 52, to rotate the pawl shaft 40 and thus rock the pawl 42 to cooperate with a recess 28 in the driving member. The lever 43 rigid with the other pawl shaft 40 is operated through the engaging portions 59a, 60 of the two levers and rotates the other pawl 42 into engagement with the opposite end of the adjacent recess 28, thus positive drive is given by one pawl and over-run due to the tool meeting the work is prevented by the other pawl. The cam 71 driven from the driven member contacts a cam surface 65 of a lever 63 to swing the lever about its pivot and cause it to move the catch 67 against a spring-loaded member 69 whereupon the spring 61 returns the member 56 to its operative position where it contacts the lever 49 and rotates the pawls 42 to their inoperative position, thus providing a one-revolution clutch. The lever 63 may be swung out of the way for continuous running, in which case control is manual only from the bell-crank lever 70.

Title: New monoazo-dyestuffs and their manufacture and use
IPC: C09B62/026
Filed: 1959-10-13
Abstract: The invention comprises water-soluble monoazo dyes of formula <FORM:0907815/IV (b)/1> wherein D is the residue of a diazo component and X is a pyrimidine or triazine residue containing a halogen atom which is bound to a carbon atom next to a nitrogen atom of the heterocyclic nucleus and metal complexes thereof.  They are prepared by condensing an appropriate metallised or metal-free aminoazo dye with an at least dihalogenated triazine or pyrimidine.  When a trihalo-s-triazine is used it may be reacted, before or after reaction with the aminoazo dye, with ammonia, an alcohol, phenol or mercaptan or a primary amine under conditions so that the final product contains a halogen atom.  The non-metallised dyes may also be obtained by coupling a diazo compound with a 1-naphthol-3-sulphonic acid having in the 5-position a halotriazinyl- or halopyrimidinyl-amino group.  Copper, nickel, cobalt and chromium metal complexes are specified.  The dyes may be used to dye silk, leather, wool, superpolyamide, superpolyurethane and especially cellulose fibres, in red shades. The dyeings on cellulose may be fixed by treatment with alkali. In Examples: (1) the dye 2-aminophenol-4-sulphonic acid --> 1-amino-5-naphthol-7-sulphonic acid is prepared, coppered, and the copper complex condensed first with cyanuric chloride and then with aniline-3-sulphonic acid; (2) the condensation product of equimolar amounts of 1-amino-5-naphthol-7-sulphonic acid;and 6-(41-sulphophenyl)- amino- 2:4-dichlorotriazine is coupled with diazotised 1-aminobenzene-3-sulphonic acid.  Many further examples are specified.  Specifications 797,946, 822,047, and 838.337 are referred to.

Title: Synchronisation device for change-speed gears
IPC: F16D23/06
Filed: 1962-09-13
Abstract: 943,960. Positive clutches. F. A. E. PORSCHE. Sept. 13, 1962 [Sept. 16, 1961], No. 34949/62. Heading F2C. A change-speed gear synchronizing device, in which a toothed shifting sleeve held by a sleeve carrier member rigid with a driving shaft may be engaged with a gear, has a primary friction member co-operating directly with the teeth of the shifting sleeve and a secondary friction member frictionally engaging the sleeve carrier member. Axial movement of a shifting sleeve 6 to engage internal teeth 7 with teeth 8 rigid with a gear 2 freely rotatable on a shaft 1 to which a sleeve carrier 4 is secured, first produces frictional contact between the crests of the teeth 7 and the periphery of a split synchronizing ring 9. The ring 9 moves in the direction of rotation to contact an abutment member 16 which contacts one end of a supporting ring 15, the other end of which moves an outturned end 21 of a clamping band 10 to engage the band frictionally about the hub 19 of the sleeve carrier 4, the other outturned end of band 10 being held against the edge of an aperture 22 in an axial flange 11 of the gear 2. With lack of synchronizm between the clutch elements the band 10 is held against the hub 19 and the supporting ring 15 bows outwards under compression to urge the split ring 9 into contact with the teeth 7, thus preventing positive engagement of the teeth 7 and 8. When synchronizm is attained the ring 15 relaxes and the sleeve 6 may continue to move axially to engagement. In other embodiments, the secondary friction member may expand or contract into contact with an axial flange on the sleeve carrier between the hub and the sleeve carrying teeth or the supporting ring may have an additional conical friction surface engaging a complementary surface on the sleeve carrying member.
