Title: Method of and apparatus for making ceramic or vitreous articles
IPC: C03B13/00
Filed: 1965-04-20
Abstract: <PICT:1098833/C1/1> Ceramic or vitreous heat exchangers are made by producing one or two ribbons of ceramic or vitreous working material having a varying transverse thickness, reducing the ribbons to a constant transverse thickness, corrugating at least one ribbon, winding the ribbon helically and adhering adjacent faces of the ribbon or ribbons together to form a unitary structure. A ribbon 13 of material is fed to a pair of inclined rolls 15 to form the transverse taper of about 0.008 to 0.012 inch.  The ribbon is then passed to a pair of conically shaped crimping rollers 17 which are set to reduce the ribbon 20 to a constant transverse thickness of 0.008 inch and thereby cause the ribbon to curve before being wound helically upon a mandrel 11. Reference 26 indicates heaters. With one ribbon the corrugations are so arranged that a hump in one layer contacts and adheres to the hollow of an adjacent layer, thus forming a series of radial passages between layers. Alternatively, a plain ribbon 12 may be interleaved with the corrugated ribbon.  A preferred glass composition is 45.5% SiO2, 38.1% Al2O3, 9.2% Li2O, 3.25% TiO2, 0.15% Na2O, 3.8% SnO2 and 1-8% F.  A preferred ceramic composition is 75 parts by weight petalite and 25 parts by weight of a glass-ceramic of composition 70% SiO2, 18% Al2O3, 5% TiO2, 3% LiO2, 3%MgO, 1% ZnO. Another suitable ceramic material consists of 28% b -spodumene and 72% petalite with polyethylene glycol as a binder.  The non-plastic ceramic material is made extrudable by the addition of a binder-plasticizer-solvent mixture.

Filed: 1956-05-29
Abstract: 850,518. Gear pumps. CARVER, P. W., and KONTAK MANUFACTURING CO. Ltd. May 29, 1957 [May 29, 1956 (2)], Nos. 16650/56 and 16652/56. Class 110 (2). [Also in Group XXVIII] A gear pump 110 having inlet and outlet passages 12, 11 circulates liquid to actuate a diaphragm pump (see - Group XXVIII). The pump is driven by an electric motor 111 and a reservoir chamber 117 is provided above the pump which is partially filled with liquid to a level 118 providing an air space 119 above it vented to the atmosphere. The pump delivers a greater volume of liquid than that required to actuate the diaphragm pump and the excess delivery is by-passed through a valve 120 to the reservoir from which liquid is drawn past a valve 121 to the suction side of the pump. Air bubbles in the circulating circuit flow through the inlet 12 and pass upwardsthrough an orifice 126 to a float chamber 125 containing a float valve 124 which controls an orifice 122 communicating with the reservoir chamber. As the air collects in the float chamber the valve 124 falls until the orifice 122 is opened when the air passes into the reservoir chamber and to the atmosphere and liquid flows from the reservoir into the float chamber until the valve 124 is raised to close the orifice 122.

Title: Improvements in and relating to processes for the production of varnishes
IPC: C09D101/18
Filed: 1929-05-30
Abstract: 312,923. International General Electric. Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). June 1, 1928, [Convention date]. Paints, varnishes, &c.-Solutions of high concentration containing cellulose varnishes and condensation products of polyhydric alcohols and polybasic acids or anhydrides, such as the product obtained from phthalic acid and glycerine, are obtained by the use of homogenising means comprising benzene derivatives which are known to be good solvents for artificial resins known under the Registered Trade Mark " Glyptal," such as nitrobenzene, and pyridine, and benzaldehyde. Mixtures of the above may also be used. The usual solvents for the cellulose derivatives and resins are used, and the flexibility of the resulting films may be increased by the addition of plastifiers. The amount of homogenizing means added depends upon the degree of condensation of the resin, and also upon the use of a suitable solvent for the homogenizing means, if desired, e.g. the amount of nitrobenzene required may be reduced by the addition of ethylene-glycol. Specification 303,915 is referred to.

Title: Improvements in or relating to apparatus for dynamically balancing a rotatable member during rotation of the member
IPC: G01M1/30
Filed: 1960-05-12
Abstract: 898,766. Automatic balancing control systems. LARSH, E. P. May 12, 1960, No. 16815/60. Class 38 (4). In Figs. 1, 2, the shaft 16 of a rotor 14 to be dynamically balanced during rotation is supported at each end in a bearing member 24 which is mounted by means of a resilient ring 26. A detector to respond to lateral movement of the bearing member 24 with respect to a main support 12 comprises a pair of contacts, 38, 40 which control actuation of a piston 64 by a solenoid 56. A rod 74 of easily fusible material is fed into a heated tube 70 and means for rotating feeder wheels 78 may be associated with operation of the solenoid armature 58. A further heated tube 90 connects with the housing 66 carrying the piston 64 and the free end of the tube is in alignment with a groove 96 in the rotor 14. If the rotor is unbalanced, lateral movement of one or both bearing members 24, 30 will take place when the rotor is driven by a motor 142 and the associated contacts will close momentarily to cause a spray of the weight material 74 to be forced into the rotor grooves. To allow for the time lag between the closing of the contacts and the ejection of the weight material from the tube 90, adjustment of the contacts around the periphery of the rotor is provided for. In a modification, a body may be injected into the groove from a " gun." Rotor blades may be balanced by adding weight material, Fig. 6 (not shown). The means for detecting unbalance may comprise a light beam which normally strikes a photo-cell but which is interrupted when the rotor moves laterally. In Fig. 8, a photo-electric receiver 311 is connected through a control unit 312 to an actuator mechanism 314 which includes a ramrod 336. A plunger 334 operates the rod and its head 332 is engageable by an impact member 330 attached to a clutch plate 324. Upon the light beam to the receiver being interrupted the coil 326 of the clutch is energized and the plate 324 rotates with a driven disc 320. A ball and cam device 350, 344 causes disengagement of the plate 324 and disc 320 before the impact member 330 strikes the plunger head 332. In a further embodiment, Figs. 14-19 (not shown), projectiles for weighting purposes comprise portions severed from wire which is drawn into the apparatus, the projectiles being pneumatically ejected from a barrel.
