IPC: B44C1/22
Filed: 1956-11-19
Abstract: 851,857. Ornamenting. COMPAGNIE DE SAINT-GOBAIN, [formerly MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE SAINT-GOBAIN, CHAUNEY & CIREY S.A., DES]. Nov. 19, 1956 [Nov. 18, 1955], No. 35358/56. Class 93. [Also in Group XXIII] A process for decorating articles, e.g. glass dishes 1, by applied materials, e.g. enamel or paint, comprises applying the material to the whole surface to be decorated and removing the material from selected zones by means of one or more rotatable rubbing tools 37, 51, e.g. brushes with radially extending wire, or discs of felt. The rubbing tools may be suitably profiled. The dish 1 is mounted on a rotatable shaft 3 driven through a toothed wheel 6 on the shaft 3 engaging a toothed wheel 7 driven by a motor, the wheel 6 performing two revolutions per revolution of the wheel 7. On the shaft of the wheel 7 are two superposed cams 13, 14 cooperating reprectively with plungers 20, 19 which are urged towards the cams by springs 24, 23. The plungers 19, 20 have each a toothed surface 25, 26 engaging respectively toothed wheels 31, 38. The cams are positioned so that for one half of a revolution of the wheel 7, i.e. each alternate revolution of the shaft 3, the plunger 19 is actuated to rotate the wheel 31 to rotate a column 32 about a vertical axis and swing the brush 37 clear of the dish 1, and the plunger 20 is actuated to rotate the wheel 38 and thus, through a toothed wheel 39 and racks 42, 59 on a rod 43, to rotate a toothed wheel 60 about a shaft 48 which rotates an arm 49 carrying the brush 51 to lift the brush 51 out of contact with the plate 1 and raises a dome 56, which bears resiliently on the dish 1, through a linkage 52...54. On the succeeding half revolution of the wheel 7, the cams 13, 14 operate conversely to bring the dome 56 down onto a new plate 1 and put the brushes 37, 51 into engagement therewith. In a modification not specifically described, it is stated that the dish 1 may be stationary, and the brushes are then displaced about the dish.

Abstract: 855,040. Stuffing-box substitutes. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Nov. 11, 1958 [Nov. 15, 1957], No. 35635/57. Class 122 (5). A sealing arrangement comprises a rotor 1 and stator 2 separated by a clearance gap 3 and an annular nozzle 9 for discharging a circumferentially-continuous sheet of sealing fluid across the gap so as to prevent the escape therealong of the fluid being sealed. The stator 2 is in the form of a casing 4 having inserts 5, 6 which together define a sealing fluid chamber 7 and the annular nozzle 9. In operation, pressurized sealing fluid, such as air, is fed into the chamber through a passage 8 and is discharged through the nozzle such that it impinges on the surface of the rotor; a gauze 10 is provided in the chamber to improve the fluid distribution before entering the nozzle. The nozzle may be arranged to direct the sealing fluid towards the direction of leakage flow as shown, or perpendicularly thereto. In a modification, an arcuate groove may be formed in the surface of the rotor opposite the nozzle so that the sealing fluid impinging on the rotor follows a scroll-shaped path, thereby increasing the sealing effect. In the modification shown in Fig. 2, the clearance gap between the rotor 1 and the insert 6 is greater than that between the insert 5 and an arcuate shoulder 11 is formed on the rotor so as to prevent turbulance of the sealing fluid impinging thereon. The arrangement may also., be applied to the case wherein the outer member 4 is the rotor and the inner member 1 the stator, and wherein the surfaces to be sealed lie normal or at an angle to the axis of rotation. The nozzle may be provided on the rotor instead of, or in addition to, the one on the stator and more than one nozzle on either member may be provided. Specification 774,503 is referred to.

Title: Manufacture of dicarboxylic acid chlorides
IPC: C07C51/60
Filed: 1933-12-19
Abstract: Succinyl chloride and o-dicarboxylic acid chlorides of the benzene series are made by treating the corresponding acid anhydrides with thionyl chloride at a temperature above the melting point of the anhydride.  The reaction may be effected by adding thionyl chloride slowly to the fused anhydride at atmospheric pressure or, less advantageously, by heating a mixture of the anhydride and thionyl chloride under pressure.  A metal salt of acid reaction, e.g. zinc chloride or aluminium chloride, may be present as a catalyst.  An example is given in which phthalyl chloride is prepared by adding thionyl chloride slowly to fused phthalic anhydride maintained at 200--240 DEG  C. and containing a little zinc chloride.  Reference is made also to the production of chlorophthalyl chloride.

Title: A thermostatic electric control instrument
IPC: G05D23/275
Filed: 1960-10-20
Abstract: 904,644. Thermal switches. SCHLAICH, R., [trading as MOTO METER H. SCHLAICH]. Oct. 20, 1960 [Oct. 24, 1959], No. 35956/60. Class 38 [5). [Also in Group XXXV] A control instrument for maintaining the temperature of a medium constant comprises an indicating pointer 16, an adjustable setting pointer 18, a first contact arm 50 elastically coupled by way of a spiral spring 52 to the pointer 16, and a second bimetallic contact arm 30 which carries a heating coil 31 and which is rigidly coupled to the pointer 18 although thermally deflectable in relation thereto. In operation, the pointer 18 is set by knob 17 to the required temperature, whereby contact 30a on arm 30 engages contact 50a on arm 50 which thus moves with arm 30. The electrical circuit (Fig. 3, not shown) completed by the contacts 30a, 50a causes the heating means for the medium to operate and causes current to flow through the coil 31 so that the bimetallic arm 30 deflects away from the pointer 18 by a certain angle of lag. When the indicating pointer 16, under the influence of temperature-sensing means 40 and Bourdon tube 37 reaches the temperature indication corresponding to the angle of lag, further deflection of the pointer 16 lifts contact arm 50 clear of contact arm 30 to break the electrical circuit, and to de-energize the heating means for the medium. The bimetallic arm 30 also cools, and tends to resume its normal alignment with indicating arm 18; in doing so, contacts 30a and 50a again come into contact and the heating cycle is reestablished. The set temperature is thus approached in a series of steps. A potentiometer 58 is included in the circuit for the heating coil 31 so that the angle of lag may be adjusted. In a modification (Fig. 4, not shown) a maximum temperature cut-out is provided.

Abstract: 1361467 Restoring deformed rolls BRAMMALL Inc 2 Aug 1971 [4 Sept 1970] 36137/71 Headings B3Q and B3J A deformed roll of sheet material is restored to cylindrical shape by inserting in the deformed core at least four shoes which are pivotally joined together in end to end relationship, each shoe having an outward arcuate curvature which defines a segment of a circle having a diameter substantially equal to the inside diameter of the undeformed core, and expanding the members using a power means. In the embodiment shown in Fig. 1 five shoes 22, 24, 26, 28, and 30 are pivotally connected by pins 44 and the ends 38 of shoes 28, 30 engage a member 66 having ears 68 for removably retaining the member on a cap 54 of a piston-rod associated with a ram 48. Extension of the piston-rod causes the shoes to expand to the circle 42 of the undeformed core. The piston-rod is further extended by a small amount to completely eliminate the deformed area. A "keystone" engagement of the member 66 and roll bars 70 with roll bars 74 of shoes 28 and 30 is formed on retraction of the piston-rod so that the ram 48 can be removed. In the embodiment shown in Fig. 6 the ram 48 is replaced by a toggle linkage 118, 120, 132, 134, the latter being actuated by a piston-rod 98. In the embodiment shown in Fig. 8 a plug 88-1 is inserted at one end of the core after the end shape has been restored. The shoes 22-30 are then moved to the other end, expanded, and a plug 88-2 inserted. A hooked tool 154 is used to engage rings 152 on the pins 44 so that the shoes can be removed from the core after insertion of the plugs. In the embodiment shown in Fig. 12 a member 220 is raised by a toggle linkage 90 to expand shoes 206, 208, 210 and 212, the member 220 having ears 224 and 226 for engagement with bars 230, 236 mounted on the shoes 210, 212. At full extension of the toggle linkage an arcuate surface 222 of the member 220 completes the circle formed by the shoes.

Abstract: 1360692 Decopperizing lead AMERICAN SMELTING & REFINING CO 4 Aug 1972 36536/72 Heading C7D A process for de-copperizing Pb containing a small amount, e.g. < 0À1%, of Cu, comprises adding NaOH or KOH and pyrite (FeS 2 ) to a melt of the Cu-containing Pb, and agitating the melt. The Cu forms sulphur compounds with the pyrite, e.g. CuFeS 2 , Cu 2 S, CuS, which separate into a dross. To assist in the formation and separation of the dross, any of NaCl, KCl, Na 2 CO 3 , K 2 CO 3  and borax may be added. The pyrite, which may be present as a concentrate, and the alkali are present in the range 0À1-0À25% and 0À13-0À3% respectively. The melt can undergo two decopperizing stages, in which it is reacted with e.g. NaOH and pyrite in the second stage, and with the dross from the second stage in the first stage. The Cu content can be reduced to 0À0025%, and the de-copperized Pb can be subsequently de-silvered.
