IPC: C08G8/36
Filed: 1944-12-27
Abstract: Phenol-formaldehyde resin solutions giving good adherence to plain degreased metal surfaces are obtained by reacting phenol and formaldehyde to form an A stage phenolformaldehyde resin in the presence of an alkaline catalyst and from 5-30 per cent by weight of the resin of a volatile plasticizer comprising glycols, glycerine, camphor, camphor oil, organic phosphates or glyceryl triacetate and dissolving the resin in a volatile solvent, e.g. alcohol.  The volatile plasticizer should have a b.p. of 250 DEG  C. so that during the drying of the coating while the solvent is being removed and the resin converted to the B stage the plasticizer remains in the film, but during the final conversion to the C stage is removed.  100 parts phenol, 100 parts 40 per cent formaldehyde, 2 parts ammonia (26 Be) are reacted in presence of (a) 20 parts light camphor oil, (b) 20 parts synthetic camphor, (c) 25 parts glycerine, (d) 25 parts glyceryl triacetate.

Abstract: 725,529. Joint-making packing. ZAGORSKI, sen., J., and ZAGORSKI, jun., J. Sept. 19, 1953, No. 25916/53. Class 122 (3). In a method of making gaskets from cord made of asbestos, cotton or other fibrine the cord is impregnated with an inorganic binding agent, for instance water glass or silicone liquid, or with an organic binding agent, for instance varnish or rubber, and then wound spirally to the desired dimension on a disc round a mandrel, the ends of the cord being wired, and, in the case of wire core cords also soldered or welded, to the neighbouring windings, to form a closed ring. The closed rings are then impregnated with a mixture of an inorganic binding agent, for instance, water glass, and graphite or talcum powder, or with a mixture of an organic binding agent, for instance, varnish or rubber, and graphite or talcum powder or treated with talc, and finally moulded under pressure to the desired dimension.

Title: Fluid operated piston and cylinder assemblies

Filed: 1972-06-02
Abstract: 1381982 Controling fluid actuators MESSERSCHMITT-BOLKOW-BLOHM GmbH 2 June 1972 [30 July 1971] 25924/72 Heading F1P In Fig.2, with a reversing valve 19 as shown, the right side of a piston 12 is pressurized through a line 15 and the piston displaces fluid through a line 14 to a reservoir 21. Because of the pressure difference between lines 14, 15 a foil 33 moves to the position shown and closes a port 36, thus preventing back-pressure on the piston 12 which would normally be caused by the flow of fluid through the throttle valve 17 and conduit 14 to the reservoir 21. Throttles 38, 39 with a lower rate of flow than throttles 17, 18, may be provided to give a more rapid change-over of the foil 33. In Fig.3, when the valve 51 is as shown, a foil or diaphragm in a device 42 closes conduit 48 so that line 15 is connected to the reservoir 21. The foil of device 41, due to excess pressure in pipe 14 as compared with the reservoir, is pressed against outlet 45, so that pressure fluid enters the left hand end of the cylinder. Fig.4 (not shown), illustrates an embodiment in which the changeover valve 51 of Fig.3 is replaced by two independently operable valves so that the piston may be arrested in any desired position. Non-return valves are also provided between the throttles 17, 18 respectively and the device 31.

Class 68(1) A mechanism in an endless chain cutter jib for automatically tensioning a cutter chain of a mineral-mining machine to compensate for the wear and stretch of the chain due to use. The mechanism is positioned within the jib 15 and between it and a supporting jib post 14. Extending from the jib 15 is a rack 28 and a stop 25. A helical spring fits about the stop 25 and a stop 24 on the piston rod 27 of an hydraulic jack 23 mounted in the jib 14. Associated with the rack 28 is a ratchet 31 on a lever 30 pivotally mounted on the jib post 14 and arranged to operate under certain conditions a pump 29 that controls the advance of the piston rod 27 of the jack. When the cutter chain is under tension the jib slides inwards on the jib post until the stop 25 engages the stop 24, the ratchet 31 sliding over the rack 28. On the tension in the chain due to cutting being relaxed the jib is moved outwards by the spring. The chain is always maintained at a constant tension when idle since on the jib moving outwards the rack is engaged by the ratchet with resultant movement of the lever 30, operation of the pump 29 and advance of the piston rod to an extent equal to that of the jib to compensate for wear of the chain during the previous usage.

Abstract: 973,723. Cams. CONCAST A.G. July 9, 1962 [July 13, 1961], No. 26208/62. Heading F2K. [Also in Division B3] A continuous casting mould is reciprocated by a cam disc provided on at least one face with a cam path comprising recurrent equal cam path sections and operating follower rollers arranged symmetrically in a number corresponding to the number of the path sections in such manner that upon rotation of the cam disc the followers transmit simultaneously equal movements to the die table. The cam disc 13, Fig. 1, is driven through gearing 5, 7 and the followers 15, 16 are attached to the underside of the mould table 1. The weight of the table &c. is supplemented by a spring 21 to maintain the followers in contact with the cam path 14, which has two equal sections each extending over 180 degrees so that both followers perform identical movements. In a modification the cam disc faces the top surface of the mould table which is supported on springs. In a further modification, Fig. 3, the cam disc has paths on both faces so that the mould table is cam actuated in both directions. The lower cam followers 37, 38 may be adjusted by set screws 66 to compensate for wear. In a further embodiment, Fig. 4, the cam followers 43, 44 reciprocate the mould table 1 through levers 47, 48, whose pivot 50 may be adjusted by hand wheel 63 during operation of the machine to vary the amplitude of reciprocation. The cam path may have more than two equal sections, and a corresponding number of followers. Reference has been directed by the Comptroller to Specification 951,334.
