Title: Improvements in or relating to lever escapements
IPC: G04B15/08
Filed: 1951-01-25
Abstract: 682,566. Clocks and watches. KAADA, 0. Jan. 25, 1951, No. 1949/51. Class 139 A lever escapement is characterized in that the lever is provided' with impact pallets which co-act with the teeth of the escape wheel to limit the arc of oscillation of the lever. The lever 5 is provided with two additional pallets 3, each set on the same side of the adjacent impulse and locking pallet 1. There is therefore no draw to banking and the pallets 3 by engaging the surface 4a of the teeth 4 of the escape wheel 6 limit the extent of oscillation of the lever 5. Banking or stop pins 7 and 8 are provided in case shock produces excess movement of the lever 5.

Title: Improvements in electric machine cooling systems
IPC: H02K49/04
Filed: 1961-01-18
Abstract: 900,726. Cooling-systems for eddy-current couplings. EATON MANUFACTURING CO. Jan. 18, 1961 [March 28, 1960 (3)], No. 2009/61. Class 64 (3). [Also in Groups XXI and XXXV] Air-turbulence in an oil-cooled, eddy-current coupling produces oil-mist which is used to lubricate the bearings. Oil, supplied to the vapour-tight casing 1 of the coupling from an inlet pipe 61 is directed through ports 63, 65 to the gap between the rotating members 19, 57 where the oil mist is formed, and thence to outlet pipe 73. The oil mist circulates in the casing to pass through and lubricate the bearings 39, 13 and escape via ports 41, 43 to rejoin the oil at outlet 73. Some mist also passes down tube 49 to lubricate bearings 15, 29 and rejoin the oil circuit via pipe 51 and port 45. Oil is pumped from a sump 101 through a heat exchanger 115 to the inlet pipe 61. A direct return line 131, 129 by-passes some of the oil directly to the sump, and a temperaturesensitive bulb 135 controls this flow to either increase or decrease the flow of oil to the coupling depending on whether the temperature of the outcoming oil is too high or too low. A pressure relief valve 111 connected directly to the sump by pipe 127 opens if the pressure in the coil circuit rises unduly. - Since the oil-mist may be explosive, a flame-suppressing ventilator (not shown, see Group XXI) is provided. An interlock 125 prevents excitation of the coupling in the absence of adequate oil-flow.

Title: Reclining seat
IPC: B60N2/23
Filed: 1973-01-16
Abstract: 1417243 Releasable fluid stays STABILUS INDUSTRIE-UND HANDLES GmbH 16 Jan 1973 [18 Jan 1972] 2145/73 Heading F2S A pneumatic piston-cylinder unit 2 for supporting a seat back 6 and adjusting its position is unlocked by actuation of a lever 11/15 which acts on a plunger 24 to open a flow path (not shown) in the unit, the lever having an abutment 13 which can engage an abutment 12 on the unit to hold the lever in the "unlocking" position, so as to avoid the necessity of manual retention of the lever. Fig. 1 and the solid lines in Fig. 6 show the unit locked and supporting the seat back in a reclined position. A sustained upward movement of the arm 11 of the lever causes the arm 15 to depress the plunger 24 and open the flow path to release the fluid lock on the unit. The unit begins to extend, and the seat back 6, if free of forces acting on it, begins to pivot into a more upright position. As the cylinder 28 moves away from the piston-rod end connection 9 the abutment 12 comes under the abutment 13 and so the lever 11/15 is retained in the "unlocking" position (dotted lines Fig. 6). The position at which this occurs may be adjusted, but as shown it begins when the seat back is in the upright position, thus allowing the seat back to be pivoted forward on to the seat and then back into the normal position without manual retention of the lever. The seat back may then be relocked in any position between upright and inclined by releasing the the lever which moves down to relieve the force on the plunger 24 and close the flow path in the unit.

Title: Improvements in or relating to the dispersion of pigments in nitro cellulose compositions
IPC: C08J3/215
Filed: 1936-01-24
Abstract: For dispersing pigments particularly carbon black and similar dusty pigments, in nitrocellulose compositions, the pigment is first mixed with a non-volatile solvent plasticizer, which may be suitably diluted, and thereafter kneaded with uncolloided alcohol - wet nitrocellulose until the latter is colloided and the pigment uniformly distributed in the plastic mass which is maintained in this condition through all the stages by suitable adjustment of the liquid contents.  The amount of plasticizer &c. used in the first stage should preferably be 1--2 times that of the pigment.  In examples, carbon black alone and in association with nigrosine are used, and dibutyl phthalate is employed as the plasticizer.  To obtain the final coating composition the plastic mass is mixed with the usual lacquer constituents and diluents.  The Specification as open to inspection under Sect. 91 refers to cellulose derivative compositions generally, and also to the use of pre-colloided nitrocellulose such as smokeless powder.  This subject-matter does not appear in the Specification as accepted.

Title: An improved automatic coupling for railway vehicles or trams
IPC: B61G1/08
Filed: 1921-01-20
Abstract: 171,059. Evans, W. J. Jan. 20, 1921. Couplings, automatic.-In an automatic coupling for railway and tramway vehicles in which, on collision of the vehicles, a link slides up an opposing hook and engages it, the link is arranged to be held approximately horizontal by means of a sliding bar on the link, or by means of a web on the link resting on a projecting ledge of the hook. The hook a has an inclined face a and a vertical post d on which a rod f is pivoted, the other end resting in a groove in the point of the hook. A link is suspended from the hole i and has two stops p, p<1> on each side of the link between which the bar q slides. Stops k, e on the hook a and post d limit the movement of the link l and rod f respectively. A hole h in the face of the hook is provided for auxiliary haulage. When the sliding bar q is against the rear stops p the link l is held in the coupling position, and when against the forward stops p<1> the link can fall to its depending position below the hook. In uncoupling, the link l is raised manually clear of the opposing hook and rod f, and allowed to fall back again on the latter, the vehicles are then free to disengage. In an alternative form of link a web is formed on the link near the hole i, which engages an horizontal ledge projecting from the side of the hook when in the coupling position. The hole i is provided with a featherway through which a feather on the end of the link passes on sideways movement of the link, permitting the web and link to clear the ledge of the hook and drop to a depending position.
