IPC: E05F15/56
Filed: 1930-03-01
Abstract: 345,457. Centrifugal separators. COMPAGNIE GENERALE DE CONSTRUCTION DE FOURS, 8, Place des Etats Unis, Montrouge, Seine, France. March 1, 1930, No. 6849. Convention date, March 2, 1929. [Class 23.] Density separotors ; treating substances with liquids. - In an apparatus for the treatment of gases to obtain physical or chemical changes the gas is distributed by a ring of nozzles through which it emerges at right-angles to a rotating impact surface; suspended particles are thrown outwards and the gas is drawn inwards to a central discharge pipe. The casing 11 encloses a chamber 1 provided with a series of nozzles 4 and an entry pipe 2. The impact surface 5 is formed by a metallic cup which can be rotated by any suitable means. The gas stream passes through the entry 2 and nozzles 4 and impinges on the surface 5. Any precipitation products or liquid particles are thrown by centrifugal force to the casing 11, and are discharged through the outlet 12, while the purified gas passes out through the central outlet 8. A film is formed on the surface 5 by liquid supplied through the pipe 10; this film assists in carrying the suspended particles outward, or it may effect some chemical action with the gas passing through the apparatus. Injectors or sprayers 14 are placed at the top of the casing for the supply of steam or any suitable liquid to clean the casing, or to heat or cool the gas supplied, or for the supply of a solvent in an atomized condition when desirable. In some cases the gas itself may contain sufficient moisture to form a film on the surface 5 and no liquid need then be supplied through the pipe 10. The surface 5 near the nozzles 4 may have radial or concentric grooves, and the nozzles may have a lip extending inwards towards the axis of the machine. A quantity of gas, after treatment, may be returned through an automatic, regulator to the entry pipe 2 so that the speed of the gas from the nozzles 4 is constant. The nozzles 4 may be replaced by a continuous circular slit.

IPC: B61K7/00
Filed: 1958-03-05
Abstract: 849,356. Wheel stops. STRACHAN & HENSHAW Ltd. Feb. 23, 1959 [March 5, 1958], No. 7130/58. Addition to 784,543. Class 104 (2). [Also in Groups XXXII and XXXIV] The device of the parent Specification, for retarding railway vehicles is modified in that the rocker 24 is secured to an inclined (or horizontal) axle 23 instead of to a part-spherical bearing. The axle 23 is mounted in a housing 11, 22 having two projections 14 with a cross-piece 15 shaped to fittingly engage a rail 16-19 so that the housing can be adjusted to firmly seat its lower face on a sleeper 13, the piece 15 and rail being bolted together. A collar 30 on the axle, has an arcuate tooth 40 engaging hardened inserts 42, 43, Fig. 4, in connected pistons 37, 38 projecting into chambers 33, 34, supplied with hydraulic fluid via one-way valves 52, 54 from a chamber 29 filled to level 45 (Fig. 3) from port 44. Rotation of axle 23 by engagement of a wheel 27, 28 with fingers 26 of the rocker 24, moves pistons 37, 38 to force fluid from one chamber 33 or 34 into the other via a passage 55 restricted by insert 56, 57, to retard the vehicle. One-way valves 60, 61 permit flow to chambers 33, 34 respectively, only when a predetermined high pressure is created in chamber 34, 33, e.g. when a fast moving truck hits the device, the additional flow through passages 58 or 59 preventing derailment of the vehicle. A further passage 62 connecting chambers 33, 34, has normally closed valves 63, 64 and grooved rods, 65, 66, which are forced apart to open the valves by a cam 67 on a rod 68, Fig. 3, to permit free flow between the chambers, the rod 68 being controlled by a spring 70 and diaphragm 71 to which is applied fluid pressure from passage 73 or a mechanical force. The valves 63, 64 are closed to hold a vehicle stationary and open to release it. When the device is used purely as a stop and release device passage 55 is omitted or blocked off. Access to adjust valves 52, 54, 60, 61, 63, 64 to a suitable loading pressure, is obtained by removing the plugs 35 from chambers 33, 34.

Title: An Automatic Lathe
Inventor: WORRELL GUY CRAWFORD
IPC: B23B11/00
Filed: 1968-02-14
Abstract: 1,177,203. Automatic lathes. G. C. WORRELL. 14 Feb., 1968, No. 7168/68. Headings B3B and B3T. In an automatic turret lathe having an indexable and reciprocatable turret 36 with a plurality of tool and/or work holding stations which correspond to a plurality of stations in a fixed headstock 26 means is provided for indexing and locking the turret in successive selected positions whereby workpieces machined from bar stock have subsequent machining operations performed thereon at the headstock stations in accordance with the indexing of the turret. The turret is reciprocated by cam and lever means 250, 240 and carries a plurality of non-rotary tool holders 50 and at least one rotary work-holding spindle 56 gear-driven from a drive spindle 63 and includes collet-type work-holding means 68. The headstock includes one work-holding rotary spindle 22 through which bar stock is fed by a reciprocating type gripper. The axis of rotation of the turret and the axis of the main spindle 22 are parallel and the turret and headstock stations are in coaxial alignment whereby indexing of the turret brings successive turret stations into co-operation with successive headstock stations. The indexing of the turret is effected by a Geneva mechanism 212, 210, 146 driven from a shaft portion 158 by a chain- and-sprocket drive 156, 154, 152. The shaft 158 is connected to a drive shaft 172 by a clutch 162 controlled by a cam and leveroperated mechanism 206, 190, 194 which sequetially operates the clutch 162 to drive the shaft 158 which effects actuation of the Geneva mechanism and indexing of the turret. Operating in co-operation with the indexing movement, a turret-locking mechanism is provided in the form of two diametrically-opposed slidable members 120 which engage in notches 110 in a notched plate 100 secured to and indexable with the turret. The slidable members 120 are actuated by levers 130, 140 from a rotary cam 146 driven by the chain-and-sprocket drive and hence the engaging and releasing of the notched plate 100 by the members 120 is in sequence with the desired indexing movements of the turret. The main drive from the motor M effects the rotation of the main spindle through belt and gear means as well as the sequential indexing and reciprocation of the turret, the turret reciprocation being effected when the members 120 are in engagement with the notched plate. In operation, workpieces machined from the bar stock in the main spindle 22 are partedoff from the bar held in the turret spindle 56 by the collet 68 and indexed therewith for machining as required by presentation thereof by the turret to the successive machining stations on the headstock, the finished workpiece being ejected from the turret spindle 56, after a completed sequence of operations and cycle of the turret, by a fresh length of bar stock fed from the machine spindle 22. Such operations as turning, boring, drilling and screwing may be effected on a workpiece during a complete machining cycle.

Title: Improvements in or relating to a process for making intaglio printing inks
IPC: C09D11/08
Filed: 1933-03-09
Abstract: 396,654. Ink. KURZ, H., 4, Elterleinplatz, and ALBERT, K., 4, Thugutstrasse, both in Vienna. March 9, 1933, No. 7238. Convention date, March 19, 1932. Addition to 371,527. [Class 146 (iii).] The process described in the parent Specification for the preparation of a body for intaglio printing-inks is modified by first saponifying the resin with aqueous solutions of alkalines or ammonia or mixtures thereof, and then adding alcohol or other volatile watersoluble organic solvent, or a solution of a resin in such a solvent. The saponification is effected with heat if necessary, and by means of aqueousalcoholic alkali lyes. The addition of a resin solution to the saponified resin produces a mixed resin varnish which is stable and does not require the addition of the high-boiling point solvents to control the brittleness of the resin film. The resin may be suspended in water by means of a wetting-agent such as soft soap, and the alkali or ammonia added. The pigments, e.g. baryta lakes of acid dyestuffs or artificial pigment dyes, are ground up with the body in the usual way. According to examples, the body is prepared by (a) introducing powdered colophony into an aqueous solution of soft soap to which spirit has been added, adding a solution of ammonia, and finally a small amount of turpentine oil; (b) adding a solution of colophony in isopropyl alcohol to a mixture of solutions of colophony in ammonia and soft soap in water ; (c) dissolving colophony in aqueous caustic potash, and adding a solution of acaroid in alcohol ; (d) adding an alcoholic solution of sandarac to a solution of colophony in a mixture of potash and ammonia ; (e) dissolving acaroid in aqueous potash, and adding spirit, ammonia, and colophony while stirring ; (f) dissolving colophony in a mixture of potash and ammonia, adding a filtered solution of shellac in spirit, and turpentine oil; (g) dissolving shellac in aqueous potash, filtering, adding colophony while stirring, and finally adding a mixture of spirit and ammonia.
