Title: Improvements in and relating to resinous compositions and methods of making the same
IPC: C08G8/28
Filed: 1939-04-25
Abstract: 527,993. Resinous condensation products. BRITISH THOMSON-HOUSTON CO., Ltd. April 25, 1939, No. 12414. Convention date. April 27, 1938. [Class 2 (iii)] Resinous compositions, suitable for casting, are prepared by blending a condensate of phenol, cresol or mixtures thereof with an aldehyde, prepared by reaction in the presence of an alkaline catalyst for a period sufficient to form the phenol-alcohol but insufficient for the product to separate into layers, with an acidic soluble alkyd resin, and de-hydrating the mixture under reduced pressure and at a temperature not exceeding 100‹ C. Suitable alkaline catalysts for the condensation of the phenol and aldehyde are hydroxides of the alkaline earth metals (calcium, strontium and barium) and hydroxides, carbonates, cyanides and borates of the alkali metals (lithium, sodium, potassium, rubidium, and calcium) especially potassium cyanide, lithium carbonate, potassium hydroxide and sodium hydroxide ; when strong bases are used neutralization may be effected be means of weak organic acids such as oxalic, malonic, aconitic, tricarballylic citric, tartaric or lactic acids. In examples the alkyd resin is prepared by condensing glycerine, phthalic anhydride, adipic acid and ethylene glycol. The resinous compositions are prepared by condensing phenol and aqueous formaldehyde in the presence of (1) sodium hydroxide, (2) potassium cyanide, (5) lithium carbonate, (7) lithium hydroxide, (8) sodium metaborate or (9) barium hydroxide, blending the condensate with the alkyd resin and dehydrating the mix. Specifications 365,140 and 421,866 are referred to.

Vapour apparatus, arrangements of.-In means for transferring energy from a direct-current system to an alternating-current system in which grid-controlled mercury vapour devices are employed, provision is made for causing the voltage applied to the grids to lead the current in the anode circuits. The desired lead for the grid potentials is obtained by connecting the primary winding of the grid supply transformer between one line of the three-phase system and a point intermediate the terminals of another phase of the three-phase transformer employed as the main transformer in the conversion system. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which the lead for the grid potentials is obtained by connecting a condenser in the primary circuit of the grid-supply transformer. This subject-matter does not appear in the Specification as accepted.

Abstract: 607,866. Iris-diaphragm valves. ANGLOIRANIAN OIL CO., Ltd., and ANDREWS, E. May 18, 1945, No. 12628. [Class 135] In an iris-diaphragm valve, e.g. for controlling the flow of liquids, the valve leaves are caused to overlap in the closing of the valve and means are provided for applying pressure upon the leaves normal to their surface when the leaves are in the closed position. The valve leaves 24 ... 29, Fig. 1, which may be arcuate or rectilinear, are accommodated in guideways 18, 19 ... 23, respectively in a circular plate 15, Fig. 2, rotatably mounted in the body 1 by means of the annular rib 16 on the plate fitting the annular recess 17 in the body, and are of reduced thickness at their inner edges so as to overlap in the closed position. A worm-driven circular control plate 39 is mounted by means of the boss 9 on the body entering the recess 40 in the plate and has slots 41 engaging studs 42 on each leaf. The recess 40 is formed with cam or wedge surfaces 53, Fig. 6, co-operating with the raised portions 55 on the boss 9 such that rotation of the control plate produces axial movement of the plate to press the leaves together.

May 1, 1931, No. 12923. Convention date, May 28, 1930. Addition to 359,967. [Class 88 (ii).] In a polyphonic musical instrument with thermionic valves as in the parent Specification, in order to reduce the number of valves employed, one valve is provided for each note of a group (a group comprising a range of notes, any of which can be sounded simultaneously by one hand, say an octave), corresponding notes in other groups being sounded by the same valves. In Fig. 1, valves L1 .. each with its plate battery P1 .. and loud-speaker or the like D1.. are provided respectively for the notes of the main group, the keys T1.. of which set circuits O1 .. in oscillation. The keys T<1>1 .. of the next and succeeding groups put the same valves and loud-speakers into action by means of circuits O<1>1.. The return R is common to all the groups. If desired also a single valve may be utilized for a note and its sharp. In a modification, Fig. 3 (not shown), a single high-tension battery is used for all the plate circuits, choke coils and condensers being inserted to prevent intermingling of the currents ; and instead of a single battery C for heating the filaments, a transformer with a secondary for each valve may be used. A separate keyboard is used for each hand.

Title: Improvements in or relating to electric motor controllers
IPC: H01H61/00
Filed: 1937-05-06
Abstract: 474,149. Control of A.C. motors ; thermal switches; snap-action switches. IGRANIC ELECTRIC CO., Ltd. May 6, 1937, No. 12943. Convention date, May 11, 1936. [Classes 38 (iii) and 38 (v)] A motor controller comprises a starting switch 1 for controlling starting connections of a motor M, a running switch 2 for controlling power connections of the motor, and thermal means heated in accordance with the current taken by the motor for controlling both switches. In the construction shown, each switch comprises a pair of U-shaped levers 7, 8 arranged in opposed relation on opposite sides of a supporting bracket 9 in a casing 3. The side arms of the levers are formed with knife edges engaging V-shaped recesses in the associated brackets 9, the free ends of the levers being connected together by a spring 13. The free ends of the levers 7 carry contacts 7b co-operating with stationary contacts 11, 12, the switches being normally in the closed position. The switches are provided with thermally-responsive operating elements 4, 5 under the control of an electric heater 6 connected between terminals 14, 15. Each of the elements 4, 5 comprises an elongated bimetallic strip fixed at one end to a terminal 16 or 17 and carrying at its free end an insulating plate 18, the insulating plates being recessed to receive the free ends of the levers 8. The operating element 4 carries an auxiliary heater 21 in the form of an insulated resistance wire connected at its lower end to the element 4 and at its upper end to the terminal 14. The device is connected as shown in Fig. 4 to control a splitphase A.C. motor M having a main winding 27 and a starting winding 28 connected 'in series with a condenser 29. On closing a line switch 25, both windings are energized, and current passes through the heating-coils 21, 6. The coil 21 provides for rapid heating of the element 4, and after a predetermined interval, the said element moves the lever 8 to the left until the spring 13 passes over the dead-centre, when the switch 1 opens with a snap action, and the starting winding is disconnected. The auxiliary heater 21 is then de-energized, but the heater 6 maintains the element 4 sufficiently heated to keep the switch 1 in the open position. The switch 2 remains closed under normal current conditions in the motor circuit, but opens on predetermined overload conditions. When this happens, the heater 6 is de-energized and both operating elements 4, 5 cool and return to normal position to reclose the switches 1 2 with a snap action, the switches being so adjusted that the switch 1 closes first. The switches may be adjusted by eccentric cams 30 engaging the elements 4, 5 and by adjustable stops 32 which cooperate with the levers 7. The casing 3 is provided with a terminal compartment 33 having wiring openings 34. In a modification, the auxiliary heating coil 21 is dispensed with.
