When the Mg content is 2.0 per cent and over Sn will be present in the range 0.01-0.10 per cent, and when the Mg content is 2.0 per cent and below either the Fe content or the Si content or both are below 0.4 per cent, up to 2.5 per cent of Cu may be present, so that when the Cu content exceeds 1.1 per cent and the Mg content exceeds 2.0 per cent, Sn may be present up to 1.25 per cent.  Ni may be present up to 1.49 per cent, so that the sum of the Ni and Mn contents is less than 2.0 per cent when the Zn content is 6.5 per cent and below.  The alloy may contain up to 1.5 per cent of Co.  Grain refining elements Ti and/or B may be present which together with the Nb do not exceed a total of 0.75 per cent.

Abstract: 667,464. Ships' hatchways. MACGREGOR. R., and MACGREGOR, J. Oct. 24, 19.50 [Feb. 23, 1950], No. 4625/50. Class 113 (i). A metal hatch cover particularly for ships' 'tween decks comprises a, plurality of sections of which the section A at one, or at each, end of the hatchway is hinged to the deck at 8 so as to be capable of swinging about the hinge into a. substantially vertical position and, abutting the section, a separate rolling section or sections B capable of pivoting up in known manner when rolled to one end after the hinged section A has been upturned. There may be a hinged section A at each end of the hatchway with a rolling section B between them. As shown, the hinged section A is a double member having two sections or leaves 6, 7 hinged together on their underface on an axis parallel to that of the deck hinges 8. The width of each leaf is less than the distance between the 'tween deck 1 and the weather deck 2 making the leaves stowable between the decks. Two lifting cables pass through sheaves 21 on the weather deck coaming, one being attached to an eye 20 on the hinged section A and the other to an eye 25 on the rolling section B which is thus stowed vertically after it has been pulled to one end of the hatchway.

Title: Filter with screen-changing arrangement
IPC: B29C48/694
Filed: 1968-01-30
Abstract: 1,215,381. Extruder changeover filters. C. J. BERINGER CO. Inc. 30 Jan., 1968 [3 Feb., 1967], No. 4790/68. Heading B5A. [Also in Divisions B1 and F2] A filter apparatus (intended for treating hot plastic, and for maintaining constant temperature, pressure and flow conditions during changeover from one filter screen to another) comprises a plurality of filter screens 92 (of which two are shown in Fig. 3), each one having an inlet port 106 and an outlet port 108, Fig. 1, and carried by a movable member 34 whereby to bring the ports of any one screen 92 into register with ports 56, 58 in a fixed body member 32; screen carrier 34 and body member 32 are in sliding interfacial contact, their ports registering at the interface; and when one screen is on stream, another one can be vented by means of co-operating by-pass vent passages 120, 134 (Fig. 8). Operation.-As described, inlet 44 and outlet 54 are connected in line between a plastic extruder and its die (not shown). Hot plastic flows into a first screen chamber via passages 46, 48, and matching ports 56, 106, and out via 107, matching ports 108, 58, and passages 50, 52. Thus filtration occurs and screen 92 becomes clogged. Rotation of screen carrier 34 (out of the plane of the diagram as viewed in Fig. 1) is then caused by a ram (110) (triggered by an increase in pressure drop across the clogged screen). As shown in Fig. 3, but especially in Fig. 7, this results in some hot plastic being bled off into a second screen inlet port 116, filling the next screen chamber which is thus pre-warmed; air in the chamber can escape via a recess 120 (in body member 32) and a vent passage 134. As the screen carrier rotates further (either in response to the conditions inside the screen, or to a time-switch), recess 120 gets closed so that pressure builds up in the second screen chamber (Fig. 10, not shown). Next, (Fig. 12, not shown), outlet port 58 comes into communication with port 118; the second screen chamber is thus partly on-line, and a flow condition is thus established. In succeeding stages (Figs. 13-18, not shown) the second chamber is brought completely online while the first chamber is brought off-line and vented via recess 122 and passage 134. Alternative embodiment.-Instead of rotary movement, the screen carrier may move rectilinearly (Figs. 19-27, not shown), transversely with respect to the flow-line in the fixed body member.

Classes 34(2) and 64(2) Pulverulant material is heated or cooled by entrainment in a current of gas which flows through a tube in a helical path induced by vanes attached to a member extending through the tube. Fig. 1 shows a drying apparatus in which the material from a hopper 11 is entrained by a stream of gas issuing from a pipe 13 having a heater 14 and flowing up through a steamjacketed tube having an inner rotary tube 22 carrying vanes 23 and also heated if desired. The material is separated from the gas in a cyclone 20. In a modification, the stream of gas with entrained material flows down through a tube 4, Fig. 2, having an inner tube 5 carrying vanes 6. The material is separated from the gas in a tube 8 and falls into a receiver 10, while the gas flows up through the tube 5. Separation of the finer particles is facilitated by a guide member 9 which increases the rotation of the gas stream.

Abstract: 1415392 Determining rotational plane of a wobbling wheel HUNTER ENG CO 31 Jan 1973 [17 March 1972] 4972/73 Heading G1N Apparatus for determining the true plane of rotation of a wobbling wheel comprises means for measuring the angle between the plane of the wheel and the vertical at two positions of the wheel which are 180 degrees apart, from which the true plane of rotation can be obtained. As shown, Figs. 1, 2 and 3, a frame 13, mounted on the wheel rim 14 by clamping between pins 15, 17, carries a plate 23 which is fixed to the wheel axle 22 and has two apertures 24, 25 on one side and a third aperture 26 diametrically opposite. An extension of the axle 22 carries a housing 27 which is hanging vertically on the axle, and carries a first switch 34 at the same radius as aperture 25 and a second switch 33 at the same radius as apertures 24, 26. The wheel 12 carries a sensor 35 which measures the angle between the plane of the wheel and the vertical. The wheel is rotated so that a signal from sensor 35 is fed to a first memory unit, when both switches 33, 34 are operated when they are opposite apertures 24, 25, and to a second memory unit after a further 180 degrees rotation of the wheel, when switch 33 is opposite aperture 26. The two signals are added and halved to give a value representing the angle between the true plane of rotation of the wheel and the vertical, i.e. the angle between the wheel axle and the horizontal, i.e. the wheel camber. By measuring the angle between the plane of the wheel and the horizontal the toe-in or toe-out of the wheel can be determined by the same apparatus.

Abstract: 158,912. Robinson & Son, Ltd., T., Robinson, C. J., and Stevenson, T. J. April 10, 1917. Conditioning and damping grain.-Moistened grain is treated with warm air having a regulated moisture content, and subsequently with a current of cold air to condition it. The grain from the hopper k falls down a conduit having perforated side walls b<1> and solid end walls into the boot of an elevator l which delivers it to a hopper k<1> and a second similarly constructed conduit from the bottom of which it is discharged in a cooled and conditioned state. The current of hot air is induced by a fan e placed above an ordinary cyclone separator f. The current from the fan passes through a pipe i to an ordinary airheater d and thence into a passage b<2> arranged between the grain conduits and having passed through the grain in the conduit enters the separator f and the fan e. The current of cold air is induced by a second fan e<1> placed over a second cyclone separator f<1>. Cold air is drawn into a passage c formed at one side of the lower half of the second grain conduit, through the grain into a passage c<1> and then into the entrance f<2> of the separator f<1>. If the warm air current is not sufficiently moist, water or steam may be sprayed into the passage b<2> at the point g. The water used may be that collected in the separator f after having passed through a filter in the tank h.
