Title: Improvements in or relating to resinous compositions and varnishes made therefrom
IPC: C08G8/28
Filed: 1928-07-09
Abstract: 324,025. Bakelite Corporation, (Assignees of Turkington, V. H.). July 7, 1927, [Convention date]. Divided on 293,453. Synthetic resins.-In the process of making a resinous composition, reaction is effected between a phenol such as phenol or cresol, and a fatty oil in the presence of a non-phenolic acid resin, other than a resin of the polybasic acid-polyhydric alcohol type, with or without the addition of alkaline, neutral or acid condensing agents. Most acid neutral resins such as resin, manila and other copals or elemi may be used. Tung oil is preferably used, but may be substituted wholly or in part by other fatty oils such as linseed or rape oil. The product so obtained is heated with an active methylene-containing substance such as formaldehyde, whereby a product is obtained which may be dissolved in solvents such as turpentine, toluene &c. to form varnishes. In an example a mixture of phenol, rosin and tung oil are refluxed from one to 10 hours. Formaldehyde and aqueous ammonia are added and boiling under reflux continued for four to eight hours. The water is then removed by boiling, and heating continued at 150‹ C. until a clear, non-tacky solid is produced on cooling. Specification 267,736 is referred to.

Abstract: 603,270. Gauging-apparatus. GENERAL ELECTRIC CO., Ltd., SCRUTON, A. H., and DIXON, H. Nov. 28, 1945, No. 32137. [Class 106 (ii)] An external gauging machine for short tubes or rods comprises a row of gauges of increasing gauge size, means for transferring the tubes or rods to successive gauges while supporting them at or adjacent their ends, locating members extending along and to either side of the row of gauges, and means for displacing the locating members to permit the transferring operation. As shown, Figs. 1 and 2, a supply of tubes (or rods) in a hopper 6 are fed, one by one, by a rotatable grooved drum 26 to the first carriers 12 of a set of carriers secured to a pair of longitudinal frame members 11 constituting a tube-lifting and transferring mechanism arranged to operate in timed relation with the drum 26 to advance the tubes to V- notches 29 in fixed racks 28 and thence by other carriers 12 to a row of gauges. The gauges comprise pairs of rollers 8 freely rotatable in bearing brackets 7, the spacing between the rollers of each pair being progressively increased towards the right, Fig. 1. Each tube is rested in succession between the gauge rollers until located between the rollers spaced at the appropriate size whereupon, on the lowering of the carriers 12, the tube passes down a corresponding guide 9 to one of a series of parallel tracks of a conveyer 67 and to be carried thereby to a chute 54 for delivery to a corresponding receptacle 55, the receptacles being grouped in V-formation and arranged in echelon for accessibility. Outsize tubes are transferred to a receiving tray 61. The reciprocatory and longitudinal movement of the frame members 11 is effected by a pair of cross-shafts 19 coupled to a main driving shaft and each having a crank arm 17 with trunnions 15 supporting vertical bearers 13 for the members 11. During the transference of the tubes between the gauges they are held in substantially horizontal balance by a locating means comprising longitudinal wires (or rods) 30 disposed on each side and parallel to the row of gauges and arranged lightly to, or just not to, contact the tubes when the carriers are in their lowest position. The locating wires may be secured to the carrier frame but preferably are adjustably mounted on lifting bars 32 that are operated to lift them immediately before the rising carriers engage the tubes. To this end the bars 32 are mounted on supports 31 fixed to cross-head 33 on vertical rods 34 slidable in guide brackets 35 and carrying rollers 37 which rest on angle bars 38 secured to the bearers 13, engagement being maintained by tension springs 39.

Filed: 1964-08-12
Abstract: 1,013,335. Automatic liquid level control. M. INOUE. Aug. 12, 1964, No. 32825/64. Heading G3R. [Also in Division F1] A submersible contrifugal pump P driven by an electric motor M comprises an upper electrode U and a lower electrode L which are adapted to be electrically connected to an earth by conduction through water in which the pump is immersed. The electrodes are attached to the motor casing, and the casing may form the earth E, the electrodes being insulated from it. If, however, the casing is of a poor conductor, such as synthetic resin, the earth E is formed by additional electrodes adjacent the electrodes U and L. When the water level reaches the upper electrode U, it forms a conductive path between this electrode and the earth E, whereby a relay RG, is energized from the power supply lead 11 through a transformer T and a rectifier R. A contact S 1  on this relay then closes to energize a further relay RC 2 . Contact S 2  on the latter relay closes to energize the motor M and another contact S 2 <SP>1</SP> connects the electrode L in parallel with the electrode U. The motor M consequently continues running until the water level has fallen below the lower electrode L, whereupon the relays and the motor are de-energized, and operation is not resumed until the water level again reaches the upper electrode U.
